Description

Rolling device for the side cover of a truck and method for controlling the rolling process.

The invention relates to a rolling device for the roller cover of the loading trough of a truck, according to the preamble of claim 1 and the method for controlling the rolling process according to the first method claim.

In a loading trough, especially for bulk materials such as sands and minerals, granular industrial goods or agricultural goods, such as cereals, fruits, also crushed or for scrap and other goods that are loaded from above, the cover of the hold is made with a tarpaulin, the side is fastened to the upper edge of the longitudinal side of the loading trough and pulled over the opening above which at least one or two removable crossbars are mounted to prevent loss of charge or moisture penetration.

Because the rolling and rolling a tarpaulin is very time-consuming and exhausting even on a winding tube and the more obstructive, the shorter the travel time, has already tried to install suitable arrangements that reduce this effort. For the operation, moreover, a rise and a platform is necessary.

Thus, from the applicant, a retractor is known in which the winding tube is guided over a horizontal, transversely arranged guide rail on the front end wall of the loading structure and pulled with a rubber band for tightening when rolling the tarpaulin.

With another device of the applicant was trying to apply a höhenverschwenkbares guide tube at the same place, in which the winding tube is slidably mounted on a bearing block with the guide tube or the winding tube is articulated to the bearing block on a telescopic arm.

Both designs have limitations on the unrolling and rolling up of the tarpaulin, so over the top edge of the opposite longitudinal side of the loading trough and especially because of the space requirement in front of the end wall and in relation to the arrangement of the drive and locking.

The object of the invention is in a rolling device for a loading trough to eliminate these limitations, the drive mechanically cheaper and protected to install, to simplify the lock of the winding tube and improve and to allow complete operation with remote control, from the ground. It should be possible to install the rolling device also later in loading troughs.

This object is achieved in a rolling device for a loading trough of a truck with the features of the characterizing part of claim 1.

The subclaims, which as well as claim 1 simultaneously form part of the description of the invention, relate to particularly advantageous embodiments of the invention.

In a side roller roof of a loading trough of a truck, a roller tarpaulin is attached to the upper edge of a longitudinal side of the loading trough, which is mounted on the other side on a winding tube and optionally wound on this, which is coupled at one end with an electric motor.

The winding tube is rotatably mounted on a winding tube carrier, which is fastened to a guide device which is pivotally mounted on the front end wall of the loading trough.

So that the winding roll tarpaulin takes place uniformly, elastic tension cables are wound on the two ends of the winding tube, said tension cables being guided in the region of the opposite longitudinal side via at least one cable deflection and being tensioned on the respective end wall.

Advantageously, the traction cables are made of rubber, so that the elongation extends over the entire traction cable and they lie down when rolling over guides on the end walls of the loading tray and are guyed in one of the voltage corresponding length.

When covering the loading trough, the roller tarpaulin is unrolled from the winding tube and pulled over the upper edge of the opposite longitudinal side of the loading trough and kept tensioned downwards.

The electric motor is a DC motor, which is connected via leads to a control unit and arranged protected in the winding tube.

To create a simple, reliable drive solution, the stator is. The motor mounted in a motor tube with screwed or better rivets, because they can be attached without weakening of the wall material and without protruding.

Furthermore, the rotor with the drive shaft, for the transmission of significant torque coupled via an attached square piece with a transmission part, which is also rigidly connected to the winding tube with rivets.

In the engine several successively connected planetary gear are installed in order to reduce the speed of 3000 U / min to 10 to 25 U / min, in particular about 18 U / min, and to be able to arrange this arrangement protected in the winding tube.

For supportive support of the winding tube this is provided with an extension piece which is also firmly connected to the transmission part with rivets, held in a support ring which is rigidly secured to the plate tube carrier designed as a plate and as well as this a bore for the motor and its leads having.

So that the winding tube with the roll tarpaulin is always guided to the upper edges of the loading trough a guide device is provided which balances the winding tube holding different heights on guideways, which consists of a rotary lever which is pivotally mounted on the front end wall a hinged to this telescopic tube. The latter is spring-loaded against the withdrawal direction and rigidly secured to the winding tube carrier.

By the choice of the storage point of the rotary lever on the end wall on the roll-up and the choice of suitable lengths for rotary lever and telescopic tube and its extension, the course of the winding tube on the track and the pivoting of the two parts of the guide device is achieved to each other when rolling the Rollplane from the winding tube, pivoted from a downward folding position upwards in an extended position and thereby on the installation of the loading trough, in particular the lifting device for tilting, are carried away. For the intended direction of pivoting while a pivot stopper for the telescopic tube on the rotary lever in the designated position is provided.

In this way, the dimensioning of the parts and the attachment of the guide device can be made for any dimension of the loading trough and the desired or required path of the winding tube.

For unambiguous determination of the end position of the winding tube with the rolled-up tarpaulin when rolling are on the upper edge of the longitudinal side of the loading trough several Rollplanenstopper in the form of upwardly open U-profiles that receive the rolled-up tarpaulin attached, as are at the top of the opposite longitudinal side The loading trough several closure stops attached, form the outwardly open U-profiles and take up the winding tube.

Upon reaching the respective end position of the winding tube with the Rollplane the rolling process is stopped at a preset limit of the current consumption of the motor.

For secure mounting in the two end positions of the winding tube with the roller tarp a controllable by a control unit winding barrier between the winding tube carrier and the winding tube is arranged.

For this purpose, a winding lock of the winding tube is provided, which is a gear which is mounted on the winding tube, in particular on an extension piece to this, and a roller tube support mounted on the lever system, which consists of a locking lever articulated, pneumatic, hydraulic or electrical actuating means at a locking pin attached to the locking lever, by actuation of the actuating means in a recess of the gear can be inserted.

For weatherproof coverage of the charge of the loading trough the two end walls of the loading trough are provided with upwardly curved Aufsteckwänden at the upper edges are guideways over which the winding tube rolls, whereby the design of the guide device is affected.

Because of the stable expansion of the tarpaulin on the open top loading trough a support member is at least in the middle of the roll tarpaulin, running in, which inserts when rolling the roller tarpaulin, in a recess in the middle guide track of the respective attachment wall.

When loading troughs, the rear end wall is often designed as a lift flap, the pivoting linkage when folding up enough space above the height of the upper edges also allows for tipping the load.

When folding up the resilient pull rope of the winding tube must be taken from the pivoting rear Aufsteckwand, whereby too high a cable tension would result, so after the cable deflection the pull cable is braced to an electric, pneumatic or hydraulic actuating means with which increases the cable length when folding is, wherein said adjusting means is connected in parallel with the lifting means of the lifting flap and at a hydraulic adjusting means a hydraulically tuned parallel circuit is established.

Thus, the actuation of the rolling device can be done from the ground, an electronic control device is provided which controls the DC motor driven by the winding tube and the actuating means after switching, directly or remotely controlled, automatically running according to a preset program via electrical and pneumatic or hydraulic switching means ,

After switching on the control unit, the rolling device is automatically controlled by a method depending on the command entered.

When "top open" a switching means for the actuation of the actuating means is actuated with the winding lock is opened and set with a set time delay, the motor of the winding tube in the direction of rotation "OPEN" and at "top closing" the switching means for the actuation of the actuating means is actuated the winding lock is opened and the motor of the winding tube is switched on in the direction of rotation "CLOSED" with the time delay set.

Upon reaching an end position of the winding tube, the motor, as soon as a preset on the control unit current or a detected by a measuring voltage drop in the supply voltage is switched off after a preset switch-off, and simultaneously switched a switching means with which actuates the adjusting means for inserting the winding lock is, whereby a rolling up or rolling the tarpaulin is avoided.

For the sensitive adjustment of the control is provided, the time delay for the switching on of the motor of the winding tube, and the current or voltage drop of the supply voltage for its shutdown, and the length of the engine shutdown, the control unit are each separately adjustable.

The control of the actuating means for the resilient traction cable to extend or shorten the length of the arrangement of the traction cable with adjusting means is adjustable on the control unit in dependence on the position of the pivoting movement of the lifting flap and after the Anlenkungsorte the adjusting means of the lifting flap to obtain a defined traction always ,

The invention will be described with reference to the drawing of an embodiment.
