Description

Pull wire binding tool

technical field

The invention relates to the technical field of transmission line construction, in particular to a cable binding tool.

Background technique

In the construction of power supply lines, the load-bearing poles such as expansion resistance, corners, branches, terminals and spans must be tied with pull wires to balance the force on the poles and ensure the stability of the lines. High and low voltage overhead power distribution lines generally use galvanized steel strands as guy wires. The manufacturing process of the guy wires is to bend and fold the ends of the guy wires in half, and then tightly wrap the head of the bent part with steel wires. Generally, the operation process of making the cable nose and connecting the upper, middle and lower handles is called "drawing the cable". Tighten the iron wire with a hammer. This traditional method of binding the wire with pliers needs to be wound slowly. The arrangement of the wires for winding and binding is not uniform. This method of binding the wire is not only time-consuming and laborious, but also damages the galvanized layer of the wire. Moreover, the guy wires made do not meet the requirements of the "Code for Construction and Acceptance of Overhead Power Lines"; during operation, operators are easily pulled out of deep grooves or burrs by wire cutters and easily hurt people.

Contents of the invention

The technical problem to be solved by the present invention is to provide a guy wire binding tool, which has a simple structure, is convenient to use, saves time and effort, and can quickly, accurately and closely bind the iron wire on the guy wire, greatly improving the working efficiency of the guy wire strapping. Reduce labor intensity; at the same time, it will not hurt the galvanized layer of the pull wire and the operators.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a kind of pull wire binding tool, comprising a strip-shaped plate body, the middle part of the strip-shaped plate body is provided with a long hole, and the length direction of the two ends of the strip-shaped plate body is Features a handle; also includes a guide post to redirect the wire when tying the guy wire.

Two ear holes are fixed on one side of the bar body, and the two ear holes are distributed on both sides of the long hole; the guide posts can pass through the two ear holes and are perpendicular to the long hole.

The guide post is a bolt, and one end of the bolt is equipped with a nut.

The handle is provided with a rubber sleeve.

The length of the handle is 80-120mm, and the diameter is 15-25mm; the length of the strip plate is 120-180mm; the length of the guide post is 50-100mm.

The beneficial effect produced by adopting the above-mentioned technical solution is: when binding the pull wire, one end of the iron wire is fixed on the steel strand, and the iron wire is bent through the long hole, and the guide post or 16×100 bolt is passed through the bent part and the bar. Between the shaped boards, the iron wire passes through the guide post to change the direction, and at the same time increase the friction force, so that the iron wire is tightly wound on the pull wire; among them, the guide post and the bar-shaped board are fixed as one, which is more convenient for operation and carrying; Put on the rubber sleeve to increase the friction of the hand, and it is not easy to hurt the hand; the size limit makes the structure more reasonable, lighter and more convenient to use; using this tool can quickly, accurately and tightly tie the iron wire on the pull wire , which greatly improves the work efficiency of cable binding and reduces labor intensity; at the same time, it will not hurt the galvanized layer of the cable and the operators. This tool is a very simple and practical tool for tying wires.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The production of the pull wire involves two steps:

1. Make the binding head. The purpose of making the binding head is to bend the binding iron wire into a semicircle whose diameter is equal to the steel strand, and then clamp the semicircular binding head on the steel strand;

2. Make the pull wire. Making guy wire is the core of the wire pulling operation, the purpose is to wrap the binding wire tightly and precisely on the steel strand.

The present invention will be described in detail below through two embodiments.

Embodiment one

Referring to Fig. 1 and Fig. 2, this tool includes a strip plate body 2, the middle part of the strip plate body 2 is provided with a long hole 3, and the two ends of the strip plate body 2 are provided with handles 1 in the length direction; it also includes a The guide post 4 used to change the direction of the iron wire when binding the pull wire, wherein the guide post 4 and the strip plate body 2 are separately arranged. When in use, the guide post 4 and the long hole 3 are arranged in a cross. It can be an ordinary 10×100 bolt. A rubber sleeve is provided on the handle 1, and the rubber sleeve has a friction pattern, which not only makes it comfortable for the operator to hold, prevents scratching the hand, but also increases the friction force, making the operation more labor-saving.

The length of the handle 1 is 80-120mm, and the diameter is 15-25mm; the length of the strip plate body 2 is 120-180mm; the length of the guide post 4 is 50-100mm. The limited size makes the tool more dexterous, simple in structure, and easy to hold and operate.

When specifically binding the pull wire, one end of the iron wire is fixed on the steel strand, and the iron wire is bent through the long hole 3 on the strip plate body 2, and the guide post 4 is passed between the bent part of the iron wire and the strip plate body 2. , hold the handle 1 with both hands, make the bar-shaped plate body 2 close to the backguy and turn around outside, and the iron wire will be tightly wound on the backguy. The iron wire changes the force direction through the guide post 4, increasing the frictional force.

Embodiment two

Referring to Fig. 4, the difference between this embodiment and the first embodiment is that two ear holes 5 are fixed on one side of the strip plate body 2, and the two ear holes 5 are distributed on both sides of the elongated hole 3; The guide posts 4 can pass through two ear holes 5 and are perpendicular to the elongated holes 3 . When in use, the guide post 4 is inserted into the ear hole 5, the iron wire goes around the guide post 4, and the handle 1 is held with both hands, so that the strip-shaped plate body 2 is close to the backguy and rotates outward, and the iron wire will be tightly wound on the backguy.

Embodiment Three

Referring to Fig. 3 and Fig. 4, the guide post 4 is a bolt, and one end of the bolt is equipped with a nut 6, the bolt penetrates into the ear hole 5, and the nut 6 is screwed on, so that the bolt will not fall off, is easy to carry, and prevents the guide post 4 Lost.

The structure of the tool is more reasonable, lighter, and more convenient to use; the tool can quickly, accurately, and tightly bind the iron wire on the pull wire, which greatly improves the work efficiency of the pull wire binding and reduces labor intensity; at the same time, it will not hurt The galvanized layer of the pull wire and the operator. This tool is a very simple and practical tool for tying wires.
