Description

A steel pipe rod overhead ground wire lifting tool

technical field

The utility model relates to the technical field of high-voltage power transmission line construction, in particular to a steel pipe rod overhead ground wire lifting tool.

Background technique

At present, the installation of overhead ground wires on steel pipe poles is carried by human shoulders or by means of lifting wires such as suspension tensioners. Due to the characteristics of the steel pipe pole itself, the above installation has the following problems:

1. Since the cross-arm is far away from the shaft, the method of shoulder-carrying the pole when standing on the ladder is poor in stability for high-altitude workers and inconvenient to install.

Stand on the upper wire cross arm and install it on the shoulder. For the rod type shoulder load with a long distance between the wire cross arm and the ground wire cross arm, the ground wire cannot be lifted to the installation position.

2. Use a hand-held method to lift the ground wire on the ground wire cross-arm. Since the cross-section of the ground wire cross-arm is small, the balance ability of the operator sitting on the cross-arm is poor. It is easy to use tools when lifting the ground wire and installing it by hand. Material falling off will cause damage to the ground assisting installers, and even cause the ground wire to fall and cause construction accidents.

3. Use ordinary tools to lift by hanging. Due to the length of the wire sleeve and the wire lifting tool itself, the ground wire cannot be lifted to the installation position. During the hoisting and lifting process, it is easy to cause extrusion deformation of the wire tensioner and damage to the cross arm of the ground wire, which is not conducive to safe operation after commissioning.

Contents of the invention

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a steel pipe pole overhead ground wire lifting tool, which has a simple structure, reasonable design, safety and reliability, and is suitable for the use and installation of steel pipe poles.

For the above-mentioned purpose of the invention realized, the utility model adopts following technical scheme:

A tool for lifting a steel pipe pole overhead ground wire, comprising: a steel pipe pole cross-arm clamp, a pulley bracket, and an overhead tackle, the steel pipe pole cross-arm clamp is connected to the clamp lower hoop 2 and upper clamp through the clamp connection screw 4 The hoop 3 is fixed on the cross arm 1, the tackle bracket 5 is welded on the hoop 3 on the fixture, the upward tackle is fixed on the tackle bracket 5 through the base connecting screw 6, and the upper part of the upward tackle is provided with a movable sealing plate 14, a movable sealing plate 14 The sealing screw 10 is fixedly connected with the spring pin 11, and the spring pin 11 is connected with the pin rope hanging ring through the cotter pin hanging rope 12.

Due to the above-mentioned technical scheme, the utility model has the following advantages:

1. When installing the ground wire, the operator does not need to carry it on his shoulders. According to the characteristics of various steel pipe pole types, he can choose to install it at the position of the pole ladder, wire cross arm, and ground wire cross arm to avoid loss of balance during the lifting process. Causes a short-distance fall from high altitude.

2. During the installation process, it is avoided to lift the ground wire with the shoulder or hand, and at the same time, it is also necessary to take into account the installation and cause the tool materials to fall from the sky.

3. The sky block adopts a split seal combined with a spring pin to lock, which prevents the lifting rope from falling off the block and realizes the purpose of easy disassembly and assembly.

4. The use of this wire lifting tool overcomes the difficulty that other lifting tools cannot lift the wire in place due to the length of the wire rope hanging sleeve and the wire lifting tool itself, and also avoids the damage caused by the single point force of the steel wire sleeve to the ground wire crossarm. damage.

5. The wire lifting tool is not only suitable for the installation of steel pipe poles for new lines to lift the ground wire, but also for loosening and lifting the ground wire during line maintenance.

6. The tool has the advantages of reasonable and simple structure, safety and reliability, and high work efficiency.

Detailed ways

As shown in Figures 1 a and 1 b, a steel pipe pole overhead ground wire lifting tool includes: a steel pipe pole cross-arm fixture, a pulley bracket, and an overhead tackle, and the steel pipe pole cross-arm fixture is connected to the screw 4 by the fixture The lower hoop 2 and the upper hoop 3 of the jig are fixed to the cross arm 1, the tackle bracket 5 is welded on the upper hoop 3 of the jig, the upward tackle is fixed on the tackle bracket 5 through the base connecting screw 6, and the upper part of the upward tackle is set Movable sealing plate 14 is arranged, and movable sealing plate 14 is fixedly connected by sealing screw 10 and spring pin 11, and spring pin 11 links to each other with pin rope hanging ring by cotter pin hanging rope 12.

How to use the local line lifter: Connect the lower clamp 2 of the clamp with the upper clamp 3 of the clamp through the clamp connection screw 4, fix the clamp to the cross arm 4, pass the rope through the pulley 9, and pass the sealing screw 10 1. The movable sealing plate 14 and the spring pin 11 seal the block to prevent the rope from falling off. One end of the rope will fasten the ground wire to be lifted, and the ground assisting personnel will pull the rope to the position where the ground wire needs to be installed for installation. After the installation is completed, pull out the spring pin 11. Open the movable hanging plate 14, and the rope can be removed. The design of the pin rope hanging ring 13 and the cotter pin hanging rope 12 on the block frame 7 is to prevent the spring pin 11 from falling off during the operation process. When the pole or steel pipe pole climbing ladder is installed, you can directly pull the cotter pin lanyard 13 to remove the spring pin 11, swing the rope to make the movable sealing plate 14 escape from the sealing screw 10, and remove the rope. During installation, the spring pin 11 can be selected to pass through from top to bottom. If the cross-section of the cross-arm is not hexagonal as shown in Figure 1, the wire-lifting tool fixture can change the fixture structure according to the shape of the ground wire cross-arm, and its use method is the same.
