Lifting device for electric power maintenance

Abstract

The invention discloses a lifting device for electric power maintenance. The lifting device comprises a hoisting box, a lifting power device and a lifting device body, wherein the lifting device body comprises a fixed pulley set, a movable pulley set and a pull rope, the head end of the pull rope is connected with the fixed pulley set, the tail end of the pull rope sequentially winds around the movable pulley set and the fixed pulley set to be connected with the lifting power device, the fixed pulley set is provided with a top end fixing hoop, the hoisting box is provided with multiple lifting ropes, the top ends of the lifting ropes are collected together to be connected with the movable pulley set, and a detachable support plate is arranged at the bottom of the hoisting box. The lifting device for electric power maintenance is easy and convenient to use, the defects existing in a hoisting device in the prior art are well overcome, and the work efficiency of the hoisting device is greatly improved.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a hoisting device for electric power maintenance. Background technique [0002] At present, when installing transformers in power systems, cranes are usually used for installation, but they are only used when the construction environment is wide. In narrow construction environments or fields with young crops, the crane cannot approach, which brings great difficulties to the transformer installation work. Difficult, for this reason the notification number is that the utility model patent of CN202988631U discloses a kind of power installation hoisting device, although this device has solved the problem that the construction environment is narrow and small, but still has the following deficiencies in actual use: 1. The transformer is installed between two utility poles, but the rising route of the transformer is also between the two utility poles during hoisting, so the bracket used to support t...

Problems solved by technology

[0002] At present, when installing transformers in power systems, cranes are usually used for installation, but they are only used when the construction environment is wide. In narrow construction environments or fields with young crops, the crane cannot approach, which brings great difficulties to the transformer installation work. Difficult, for this reason the notification number is that the utility model patent of CN202988631U discloses a kind of power installation hoisting device, although this device has solved the problem that the construction environment is narrow and small, but still has the following deficiencies in actual use: 1. The transformer is installed between two utility poles, but the rising route of the transformer is also between the two utility poles during hoisting, so the bracket used to support the transformer will hinder the hoisting transformer during hoisting, making the transformer 2. During the lifting process, the lifting rope is directly connected to the transformer. For such a lifting method, it is difficult to find a suitable position on the transformer. To fix the lifting rope, the second is that the length of each lifting rope is difficult to control, which will cause the transformer to be unstable during lifting, and finally cause the transformer to swing during the lifting process. If the swing is too large, it is easy to damage the transformer. 3. When using manual lifting, since there is no braking device on the winch, the worker needs to continue to rotate the rocker. If the worker does not apply external force to the rocker during the hoisting process, the transformer Under the action of gravity, it will drive the winch to rotate in reverse, causing the transformer to fall; 4. Only a single fixed pulley and movable pulley are used for hoisting. If the transformer is too heavy, it is difficult to complete the hoisting manually. Work
