Abstract

Provided is hoisting tool, comprising a support bar supported on the upper portion of an electric pole and a pulley arranged at the other end of the support bar, wherein one end of the support bar arranged with the pulley is towed to a cross-arm via at least one steel wire rope. The hoisting tool, with a simple structure, has the support bar thereof towed to the cross-arm via two steel wire ropes, thereby making the cross-arm evenly receive the stress, which is therefore unlikely damage the cross-arm. In addition, the overall structure of the hoisting tool is simple and feasible.

Description

a lifting tool

technical field

The utility model relates to a hoisting device in electric power work, in particular to a hoisting tool for equipment on a pole.

Background technique

In the electric power industry, in accordance with the requirements of the relevant regulations, the distribution line should be equipped with a switch at the outlet of the substation. If the line is longer, a switch and a metering device for marketing management must be installed in the middle, as well as the networking of the hand-in-hand line. Switches, etc., must be installed on utility poles. In places with open terrain, these devices can be hoisted to the utility poles by cranes, but when installed in mountainous areas, limited by the geographical location of the mountainous areas, the cranes cannot be driven in. Usually, a pulley is hung on the crossarm of the utility pole and pulled by manpower. The traction rope is used to hoist the equipment to the utility pole. The disadvantage of this method is: when the equipment is hoisted to the cross arm, ground personnel need to apply a force to the hoisted equipment to avoid the cross arm, which not only takes time and effort, but also increases the cross arm. Bearing capacity, when the force is too large, it is easy to cause damage to the cross arm, which poses a safety hazard.

The patent number is 200920203929.9, and the utility model patent of the invention name is "Equipment Hoisting Tool on Column". The structure of the hoisting tool is not only complicated, but also subjected to uneven force and easily damaged.

Contents of the invention

The purpose of the utility model is to provide a lifting tool with simple structure and uniform stress.

In order to achieve the above object, the utility model adopts the following technical solutions:

The utility model comprises a support rod supported on the upper part of the utility pole, a pulley is installed on the other end of the support rod;

The end of the support rod where the pulley is installed is pulled on the cross arm by two wire ropes.

The utility model adopting the above-mentioned technical solution has a simple structure, and the support rod is pulled on the cross arm by two steel wire ropes, so that the cross arm bears an average force, the cross arm is not easy to be damaged, and the overall structure is simple and feasible.

Description of drawings

Figure 1 is a schematic diagram of the overall structure of the utility model.

Detailed ways

As shown in Figure 1, the utility model includes a support rod 4 supported on the top of the utility pole 1, and the other end of the support rod 4 is equipped with a pulley 3; On crossarm 2. In this way, the cross-arm 2 is stressed at both ends, so that the force on the cross-arm is even and the cross-arm is not easy to be damaged.

Claims (2)

1. A hoisting tool, characterized in that: it includes a support rod (4) supported on the upper part of the utility pole (1), the other end of the support rod (4) is equipped with a pulley (3); and the support rod (4) on which the pulley is installed ) end is pulled on the cross arm (2) by at least one wire rope. 2. The hoisting tool according to claim 1, characterized in that: the end of the support rod (4) where the pulley is installed is pulled on the cross arm (2) by two wire ropes (5, 6).
