Description

Cross arm card coder

technical field

The utility model relates to a tool used in the construction of electric power distribution lines, in particular to a cross-arm card coder used for the installation and disassembly work of a door-shaped rod and a triple-link double cross-arm. the

Background technique

In the process of rural distribution network transformation, most of the power supply stations are located in mountainous areas, and there are many large-gauge lines in the process of outside line operation, so gate-type poles (2 poles) or triple poles (3 poles) must be used to meet the requirements. security requirements. Due to the inconvenient transportation in mountainous areas, mechanized operations cannot be realized, so manual operations can only be relied on.

During the installation and disassembly of the double cross-arm of the door-shaped rod (three-link rod), the up and down transportation of the cross-arm is carried out manually by the staff on the pole, which is labor-intensive and requires high physical fitness of the workers, especially when installing the cross-arm. very big. The process is: 6 people are required to install the portal pole cross arm, including 4 people working on the pole (2 people climbing the pole for each base pole), and 2 people assisting under the pole. The operator climbs the pole to the top of the pole, lifts the first cross-arm from the ground to the top of the pole with the rope for conveying items up and down, binds and fixes it with another rope, and then lifts the second cross-arm to the top of the pole through bolts. The two cross-arms are fastened, and after all the cross-arm bolts are tightened, the rope that fixes the first cross-arm is released, and the installation process of the entire portal pole cross-arm is completed. This method for installing the cross arm is inefficient, difficult to install, and poor in safety. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a cross-arm card coder, which can solve the problem of difficult installation and disassembly of the double cross-arm of the door-shaped rod and the triple-link rod, reduces the labor force, reduces the labor intensity of the operators on the rod, and improves Improve construction efficiency and double cross-arm installation and disassembly safety.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a cross-arm card code device, one end of the first arc-shaped hoop and the second arc-shaped hoop pass through the first mounting plate and the second The fixed adjustment bolts of the second mounting plate are connected, the bottom of the second mounting plate is provided with a pulley hanging ring, and the third mounting plate at the other end of the first circular arc hoop is fixedly installed with movable mounting bolts, and the movable bolts and the second circular arc The unclosed bolt installation groove opened on the fourth mounting plate at the other end of the hoop is matched, the bottom of the third mounting plate is provided with a pulley hanging ring, the first mounting plate, the second mounting plate, the third mounting plate and the third mounting plate Cross-arm cards are respectively installed on the four mounting plates.

Washers are installed on the threads of the movable mounting bolts. the

The bolt installation groove is "L" type installation groove.

The pulley hanging ring is a "U" ring.

The utility model provides the cross-arm coder, the first arc-shaped hoop and the second arc-shaped hoop are fixedly installed on the top of the door-shaped rod and the triple-link rod through the fixed adjustment bolt and the movable installation bolt. Hang the pulley on the pulley hanging ring at the bottom of the second mounting plate and the third mounting plate, lift the two cross-arms to the top of the pole through the rope passing through the pulley rollers and place them on the cross-arm card, adjust the two cross-arms to be parallel, Align the bolt installation holes, and tighten the bolts through the installation holes, so that the two cross arms tightly clamp the pole, loosen the movable installation bolts and take off the utility model to complete the installation of the cross arm, which can solve the problem of door-shaped rods and triple rods. The installation and disassembly of the double cross-arm is difficult, and the installation and disassembly are convenient. You only need to place the movable installation bolts into the "L" bolt installation grooves and tighten them. When disassembling, you only need to loosen the movable installation bolts to complete the disassembly. . And after safety inspection, it can effectively bear the weight of lifting and lowering the cross arm and tools and materials. Using this tool can enable the ground operators to assist the workers on the pole to carry the cross arm up and down, and at the same time reduce the number of workers on the pole, which can effectively Reduce the labor intensity of the operators on the pole, improve the safety, reduce the working time, and comprehensively improve the efficiency of the installation and disassembly of the gate pole cross arm.

Using the utility model to test the double cross-arm installation, the labor and installation time-consuming statistics are shown in the following table:

The above statistical results show that it takes 4 people and takes 19 minutes to install the double cross-arm with portal pole on average. Compared with the average installation of double cross-arm with portal pole which requires 6 people and takes 40 minutes in the prior art, the required number of people is greatly reduced. , and save working hours and improve labor efficiency; in addition, after safety inspection, the tool can effectively carry a load of 500 kg without deformation after installation, and the maximum weight of the cross-arm does not exceed 200 kg, so the utility model meets the safety conditions. Meet security requirements.

By fixing the adjusting bolt, the cooperation between the first arc-shaped hoop and the second arc-shaped hoop can be adjusted, so that it can adapt to poles with different tip diameters. For example, the tip diameters commonly used in rural distribution networks are φ150mm and φ190mm cement poles. .
