Description

A belt pressing and correcting device for belt conveyor

Technical Field

The utility model belongs to the technical field of belt conveyors, and in particular relates to a belt pressing and deviation correcting device for belt conveyors.

Background Art

Belt conveyors are widely used in chemical, coal, metallurgy, mining, building materials, electricity, food machinery and transportation sectors. They are suitable for both bulk materials and finished goods. They are particularly common in large-angle and variable-slope transportation conditions. However, the conveyor belt in the concave arc area often has a streamer phenomenon under the pull of the driving force, which creates an unsafe factor. In engineering, a belt pressing device is usually installed to solve the streamer problem. However, the traditional belt pressing device structure generally squeezes and blocks the material when fully loaded, causing the bulk material to be scattered or the finished material to pass smoothly, increasing the working resistance, and highlighting safety and environmental protection issues.

As shown in FIG. 1 , a common belt pressing and correcting device for a belt conveyor is shown, which is installed through a mounting shaft installed above the belt conveyor, on which two opposing pressure rollers 101 are installed, and the pressure rollers 101 are used to press down the concave arc segment conveyor belt 100 of the belt conveyor directly below, thereby constraining the concave arc segment conveyor belt 100, thereby realizing the function of correcting the deviation; however, since the concave arc segment conveyor belt 100 is directly pressed down from above, the pressure roller 101 and the front side of the concave arc segment conveyor belt 100 are directly pressed down, that is, the back support of the concave arc segment conveyor belt 100 and the pressure roller 101 are used as a whole to constrain the concave arc segment conveyor belt 100, at this time, the friction force of the back support on the concave arc segment conveyor belt 100 is relatively large, making the concave arc segment conveyor belt 100 easy to be damaged; on the other hand, pressing down directly from above is easy to press on the material conveyed by the concave arc segment conveyor belt 100, resulting in interference with the normal transportation of the material, such as obstruction of the passage of the material and the occurrence of material spillage.

Utility Model Content

In view of the deficiencies in the prior art, the purpose of the utility model is to provide a belt pressing and correcting device for a belt conveyor, which solves the problem in the prior art that the friction force of the back support on the concave arc section conveyor belt is relatively large, making the concave arc section conveyor belt easy to be damaged; and there is interference with the normal transportation of materials.

The purpose of the utility model can be achieved through the following technical solutions:

A belt-pressing and deflection-correcting device for a belt conveyor, wherein the belt conveyor has a concave arc segment conveyor belt, and the belt-pressing and deflection-correcting device comprises a belt-pressing and deflection-correcting assembly, wherein at least one belt-pressing and deflection-correcting assembly is installed on both sides of the width direction of the concave arc segment conveyor belt, and the belt-pressing and deflection-correcting assembly comprises:

A belt holding roller, wherein at least two belt holding rollers are provided, one belt holding roller is in contact with the front side of the concave arc segment conveyor belt in the width direction, and the other belt holding roller is in contact with the back side of the concave arc segment conveyor belt in the width direction, and the two belt holding rollers are in an opposing state relative to the concave arc segment conveyor belt;

The deviation-correcting roller is fitted with the width direction side of the concave arc segment conveyor belt and is used to constrain the concave arc segment conveyor belt from deviating in the width direction away from the center direction.

Furthermore, a plurality of belt-pressing and deviation-correcting components on the same side of the concave arc conveyor belt in the width direction are linearly and evenly distributed.

Furthermore, the belt pressing and deviation correcting components on two sides of the concave arc section conveyor belt in the width direction are arranged opposite to each other.

Furthermore, the belt hold roller rotates around its own axis. When the concave arc segment conveyor belt is running, the front or back side of the concave arc segment conveyor belt contacts the belt hold roller, and the belt hold roller is driven to rotate around its own axis through rolling friction.

Furthermore, the deflection correction roller rotates around its own axis. When the concave arc conveyor belt is running, the width side of the concave arc conveyor belt contacts the belt holding roller, and the deflection correction roller is driven to rotate around its own axis through rolling friction.

Furthermore, the belt pressing roller and the deviation correcting roller are both made of steel.

Furthermore, the belt pressing and deflection correcting assembly comprises a mounting seat, and the belt pressing roller and the deflection correcting roller on the same belt pressing and deflection correcting assembly are respectively rotatably mounted on the mounting seat via a rotating shaft.

Furthermore, it comprises a gantry, and the belt pressing and correcting assembly is fixedly mounted on the gantry through a mounting seat.

Furthermore, the gantry is provided with a plurality of mounting holes along the width direction of the concave arc section conveyor belt, and the mounting seats are fixed on the mounting holes.

Beneficial effects of the utility model:

The concave arc segment conveyor belt is constrained by two belt pressing rollers, that is, the back side of the concave arc segment conveyor belt is constrained by the belt pressing roller. At this time, there is linear contact between the back side of the concave arc segment conveyor belt and the belt pressing roller. Compared with using the back side support of the concave arc segment conveyor belt and the pressure roller as a whole to constrain the concave arc segment conveyor belt, the problem of relatively large friction force on the concave arc segment conveyor belt relative to the back side support is reduced. At the same time, the belt pressing and correcting assembly is at the edge of the concave arc segment conveyor belt, and there is no motion interference with the material transported by the concave arc segment conveyor belt, thereby reducing the possibility of interfering with the normal transportation of the material.

Embodiment 1:

According to the concept of the present application, an embodiment of a belt conveyor belt pressing and deviation correction device is described here in combination with Figures 2 and 3. Specifically, the belt conveyor belt pressing and deviation correction device is constructed as a split structure, which has a belt pressing roller 21 and a deviation correction roller 22; the belt conveyor belt pressing and deviation correction device solves the problem that the friction force of the back support on the concave arc segment conveyor belt 100 is relatively large compared to the existing back support, making the concave arc segment conveyor belt 100 easy to be damaged; and there is interference with the normal transportation of materials.

A belt-pressing and deflection-correcting device for a belt conveyor, wherein the belt conveyor has a concave arc segment conveyor belt 100, and the belt-pressing and deflection-correcting device comprises a belt-pressing and deflection-correcting assembly 2, wherein at least one belt-pressing and deflection-correcting assembly 2 is installed on both sides of the width direction of the concave arc segment conveyor belt 100, and the belt-pressing and deflection-correcting assembly 2 comprises:

A belt holding roller 21, wherein at least two belt holding rollers 21 are provided, wherein one belt holding roller 21 is in contact with the front side of the concave arc segment conveyor belt 100 in the width direction, and the other belt holding roller 21 is in contact with the back side of the concave arc segment conveyor belt 100 in the width direction, and the two belt holding rollers 21 are in an opposing state relative to the concave arc segment conveyor belt 100;

The deviation-correcting roller 22 is in contact with the side edge of the concave arc segment conveyor belt 100 in the width direction, and is used to constrain the concave arc segment conveyor belt 100 from deviating in the width direction away from the center direction.

In the illustration of the present application, it is shown that the belt holding roller 21 is located on both sides of the width direction side edges of the concave arc segment conveyor belt 100 and fits therewith, and there is linear contact between the belt holding roller 21 and the concave arc segment conveyor belt 100, and the front and back sides of the concave arc segment conveyor belt 100 are constrained respectively by the two belt holding rollers 21 on the width direction sides of the concave arc segment conveyor belt 100, thereby constraining the concave arc segment conveyor belt 100, so that the concave arc segment conveyor belt 100 always maintains a predetermined curvature state when running; at this stage, the deviation correction roller 22 blocks the side of the concave arc segment conveyor belt 100, which can effectively correct the side deviation of the concave arc segment conveyor belt 100; at this stage, the concave arc segment conveyor belt The belt 100 is constrained by two belt pressing rollers 21, that is, the back side of the concave arc segment conveyor belt 100 is constrained by the belt pressing roller 21. At this time, there is linear contact between the back side of the concave arc segment conveyor belt 100 and the belt pressing roller 21. Compared with utilizing the back side support of the concave arc segment conveyor belt 100 and the pressure roller 101 to constrain the concave arc segment conveyor belt 100 as a whole, the problem of relatively large friction force on the concave arc segment conveyor belt 100 relative to the back side support is reduced. At the same time, the belt pressing and correcting assembly 2 is at the edge of the concave arc segment conveyor belt 100, and there is no motion interference with the material transported by the concave arc segment conveyor belt 100, thereby reducing the possibility of interfering with the normal transportation of the material.

In the illustration of the present application, an overall cross-sectional schematic diagram of the belt conveyor is shown, which only shows a group of belt pressure correction components 2. Of course, in practice, multiple belt pressure correction components 2 can be provided, such as multiple belt pressure correction components 2 on the same side of the width direction of the concave arc section conveyor belt 100 are linearly and evenly distributed; of course, in some cases, they may not be linearly and evenly distributed.

In the illustration of the present application, the belt pressing and correcting components 2 on the two sides in the width direction of the concave arc segment conveyor belt 100 are arranged opposite to each other. Of course, the opposite arrangement at this time is only for the integrity and visibility of the layout; of course, in practice, the belt pressing and correcting components 2 on the two sides in the width direction of the concave arc segment conveyor belt 100 are arranged alternately; in the present application, the whole is jointly constrained by the belt pressing and correcting components 2 on both sides of the concave arc segment conveyor belt 100, so that the concave arc segment conveyor belt 100 between the belt pressing and correcting components 2 always maintains a predetermined curvature state and runs in a stable orientation.

Of course, in order to further reduce the friction between the belt holding roller 21 and the concave arc segment conveyor belt 100, if the belt holding roller 21 is set to rotate around its own axis, when the concave arc segment conveyor belt 100 is running, the front or back side of the concave arc segment conveyor belt 100 contacts the belt holding roller 21, and the belt holding roller 21 is driven to rotate around its own axis through rolling friction; that is, the rolling friction at this time is relative to the linear friction of the belt holding roller 21 in a fixed state, which reduces the friction between the concave arc segment conveyor belt 100 and the belt holding roller 21, thereby extending the service life of the belt holding roller 21 and the concave arc segment conveyor belt 100;

Of course, in order to further reduce the friction between the deflection correction roller 22 and the concave arc segment conveyor belt 100, if the deflection correction roller 22 is set to rotate around its own axis, when the concave arc segment conveyor belt 100 is running, the width direction side of the concave arc segment conveyor belt 100 is in contact with the belt holding roller 21, and the deflection correction roller 22 is driven to rotate around its own axis through rolling friction; that is, the rolling friction at this time is relative to the linear friction of the deflection correction roller 22 in a fixed state, which reduces the friction between the concave arc segment conveyor belt 100 and the deflection correction roller 22, thereby extending the service life of the deflection correction roller 22 and the concave arc segment conveyor belt 100;

With respect to the belt holding roller 21 being arranged to rotate around its own axis, and the deflection correcting roller 22 being arranged to rotate around its own axis, the belt holding roller 21 and the deflection correcting roller 22 on the same belt holding and deflection correcting assembly 2 can be respectively mounted on the mounting seat 23 by rotating the rotating shaft through the mounting seat 23.

In actual use, in order to increase the service life of the belt holding roller 21 and the deflection correcting roller 22, the belt holding roller 21 and the deflection correcting roller 22 can be made of steel; under normal circumstances, the concave arc segment conveyor belt 100 is made of rubber, and the belt holding roller 21 and the deflection correcting roller 22 are in contact with the concave arc segment conveyor belt 100, and the concave arc segment conveyor belt 100 can drive the belt holding roller 21 and the deflection correcting roller 22 to roll themselves.

The belt pressing and correcting device as a whole can be fixed in a cross-over manner above the concave arc segment conveyor belt 100 through its own gantry 24. At this time, the belt pressing and correcting assembly 2 is fixedly mounted on the gantry 24 through the mounting seat 23; in some cases, in order to improve the application of this application on different belt conveyors, the gantry 24 can be provided with a plurality of mounting holes 240 along the width direction of the concave arc segment conveyor belt 100, and the mounting seat 23 is fixed on the mounting holes 240; the position of the mounting seat 23 is adjusted according to the actual position of the concave arc segment conveyor belt 100 of the belt conveyor, so that the belt pressing and correcting assembly 2 is located at the edge side of the width direction of the concave arc segment conveyor belt 100.
