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 kind of lifting device
Technical field
The utility model relates to the hanging device in a kind of electric operating, equipment hoisting instrument on particularly a kind of post.
Background technology
In power industry, according to relevant rules requirement, distribution line will install switch additional in electric substation's outlet; Circuit is grown; Also need install the metering device that switch and marketing management are used additional, also have the networking switch of the circuit of handing in hand etc., all will be installed on the electric pole in the centre.In the open place of landform, these equipment can be with crane lifting to electric pole, when still installing in the mountain area; Receive the restriction in geographical position, mountain area, can't drive crane into, be employed in usually and hang a pulley on the electric pole cross-arm; Lean on the manpower pulling traction rope with equipment hoisting to electric pole, the shortcoming of doing like this is: equipment hoisting needs the ground staff to apply an active force of avoiding cross-arm for the equipment of lifting to the cross-arm place; Not only waste time and energy; Also increased the bearing capacity of cross-arm, there is potential safety hazard in the damage of the cross-arm of exerting oneself to cause easily when excessive.
The patent No. is 200920203929.9, and denomination of invention is the utility model patent of " equipment hoisting instrument on the post ", and the lifting device structure is not only complicated, and unbalance stress, damages easily.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure and stressed uniform lifting device.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises the support bar that is supported on electric pole top, and the other end of support bar is installed pulley; And the support rod end that pulley is installed by at least one rope traction on cross-arm.
The support rod end that pulley is installed by two rope tractions on cross-arm.
Adopt the utility model of technique scheme, simple in structure, and support bar by two rope tractions on cross-arm, make the cross-arm average force, not fragile cross-arm, and overall structure simple possible.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises the support bar 4 that is supported on electric pole 1 top, and the other end of support bar 4 is installed pulley 3; And support bar 4 ends that pulley is installed are pulled on the cross-arm 2 by one, two steel wire ropes 5,6.Like this, cross-arm 2 is all stressed at two ends, thereby makes the cross-arm mean forced, not fragile cross-arm.

Claims (2)
