Insulated Wire Rack

technical field

The invention relates to the field of electric power overhead wires, in particular to an insulated wire wire hanger.

Background technique

In recent years, the insulation transformation of overhead lines is gradually becoming popular, and PSL-12/4 lightning protection insulators are mostly used in overhead lines. When performing insulation transformation and setting out operations, in order to fix the insulated wires on the lightning protection insulator, the insulated wires must be stripped.

However, at present, when carrying out new wiring or line insulation transformation, when the operator strips the insulated wire on the pole, it is often necessary to hold the wire with his shoulders, so that the weight of the wire is all pressed on the operator, which not only aggravates the work Due to factors such as the blowing of the wind and the unbalance of the operator on the pole, it is difficult to accurately locate the stripping position, which reduces the construction efficiency and quality; at the same time, the resistance to stripping the wire on the shoulder increases the chance of damaging the wire. probability, reducing the qualified rate of stripping. According to calculations, the existing insulated conductor stripping process takes 5 minutes, the average weight of the conductor on the shoulder is 35KG, and the stripping pass rate is only 95%, so it is time-consuming, laborious and prone to errors.

detailed description

A number of specific embodiments of the present invention will be described below based on the accompanying drawings 1 and 2 .

As shown in Figure 1, the insulated conductor wire hanger provided in the first embodiment of the present invention includes a bow-shaped (or arc-shaped or similar shape) base 10, and two end point support columns respectively provided at both ends of the base 10 20 , two U-shaped end support seats 30 correspondingly arranged on top of the two end support columns 20 , and a fulcrum fixing column 40 passing through the middle of the bottom of the base 10 and arranged toward the outside of the arc. Through the fulcrum fixing column 40, the entire insulated conductor wire hanger is reliably fixed and connected to the cross arm of the overhead line pole.

The materials used to make the various parts of the insulated conductor liner can be commonly used on overhead poles, but they must be durable and have a long service life; the weight should be moderate, and can carry insulated conductors (hereinafter referred to as It is the weight of the wire), and it can be easily carried by the operator on the pole when going up and down the overhead pole.

Wherein, the bow-shaped main body of the base 10 and the horizontal connection surfaces at the two end points of the main body should be formed through one-time molding. When a wire is erected on the two U-shaped end support seats 30, there should still be enough clearance distance between the wire and the arcuate inner side of the main body, so as to ensure that a stripper can be used on the wire to perform rotary stripping.

The end support columns 20 fixedly installed on the horizontal connection surfaces at both ends of the main body can effectively increase the radius of rotation to meet the need for rotation space when the wire stripper strips. Therefore, it is necessary to design the bending degree of the main body of the base 10 (expressed as the radius of the main body) and the lengths of the two end support columns 20 to meet the requirement of the rotation radius when using the wire stripper.

In a preferred implementation structure, an aluminum alloy cable hoop can be used as the above-mentioned base 10, and the two end support columns 20 are formed by screws of a first type of length (first screws, second screws), the The fulcrum fixing column 40 is formed by another length of screw (the third screw).

Examples of further preferred parameters are as follows, that is, considering the accurate positioning of the wire stripping position and ensuring that the stripping length meets the standard, using a hoop with a diameter of 205mm (shown as a radius of 102.5mm in Figure 1), the length of the wire available for stripping is 155mm. Moreover, since the peeling operation is to realize the peeling of the insulated wire by rotating the stripper, this requires that the radius of rotation of the stripper must be greater than the radius of the stripper, that is, greater than 100mm, and the first screw and the second screw that pass through both ends of the hoop The length of the second screw basically determines the rotation radius of the peeler, for example, a screw with a length of 110mm can be used. The third screw used as the fulcrum fixing column 40 can use a screw with a length of 50 mm. In addition, a corresponding number of nuts are provided, which are used in conjunction with these screws to implement fixed connection, and the diameter of the nuts can be 16 mm.

As shown in Figure 2, the insulated conductor threader provided in the second embodiment of the present invention also includes a bow-shaped (or arc-shaped or similar shape) base 10, and two endpoints respectively provided at both ends of the base 10 Support column 20. Different from the above-mentioned embodiments, in this embodiment, a U-shaped end support seat 30 is arranged on the top of one of the end support columns 20 , and a cable clamp 50 is arranged on the top of the other end support column 20 . In addition, in this embodiment, a U-shaped splint 41 and a spring pressing plate 42 are also provided in the middle of the bottom of the base 10 toward the outer side of the arc.

Wherein, the general structure, materials, parameters, etc. of the base 10 and the end support column 20 can refer to the description in the first embodiment. For example, an aluminum alloy clamp is preferably used as the base 10 . Preferably, two hollow aluminum columns can be set as the terminal support columns 20, which are fixedly connected to the horizontal connection surfaces at both ends of the base 10; and, a flange 21 is also provided on the top of each terminal support column 20 for respectively The U-shaped terminal support base 30 and the cable clamp 50 in this embodiment are fixedly connected.

The cable clamp 50 is divided into two parts (for example, upper and lower parts, or left and right parts, etc.), there is a gap between the contact surfaces of these two parts, and one end of the insulated wire can penetrate into the The gap of the cable clamp 50 allows the other end of the wire to be mounted on the U-shaped terminal support 30 . Preferably, the U-shaped notch of the terminal support seat 30 and the gap of the cable clamp 50 are arranged opposite to each other at the same horizontal position. Torx bolts 51 are further arranged on the cable clamp 50. By tightening the torx bolts 51, enough friction can be generated to quickly lock the two parts, so that the wires therein are absolutely stable and tight. solid state, so that the wire will not rotate with the rotation of the stripper during the stripping operation. Of course, the present invention is not limited to other implementation structures (not shown in the figure), where both ends of the wire are fastened with cable clamps.

In addition, the U-shaped splint 41 is specially provided in this embodiment in order to conveniently and quickly fix and install the entire insulated conductor wire hanger on the cross arm to save operation time. The opening of the U-shaped clamping plate 41 is arranged horizontally, and the above-mentioned spring pressing plate 42 is embedded in the middle of the opening. Then, the U-shaped splint 41 can be embedded into the cross arm, and clamped by the spring pressing plate 42, so as to achieve the fixing effect on the insulated wire liner.

Various modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the above disclosure. Therefore, the protection scope of the present invention should be defined by the appended claims.
