Power system quick combination lifting tool

Abstract

The invention discloses a fast combined lifting tool of an electric system. The fast combined lifting tool comprises four support columns and cross arms, wherein the lower parts of the support columns are provided with rolling wheels; the upper ends of the support columns are articulated with upper arms, and the upper middle parts of the support columns are articulated with lower arms; fixing holes and fixing parts are uniformly distributed on the support columns, the upper arms, the lower arms and the cross arms; the four support columns are encircled into a rectangular shape and pairwise form one group; two upper arms of two support columns of each group are upwards crossed and fixed together; at least one cross arm is supported between two X frames, and the cross arm is provided with a lifting mechanism; the rest two upper arms are downwards crossed into an X shape and fixedly connected with the corresponding support columns together through the fixing holes; one lower arm of one support column of each group is slantingly downwards fixedly connected with the lower parts of adjacent support columns of the corresponding group together, and the other lower arm is slantingly upwards fixedly connected with the same support columns of the corresponding group correspondingly. The fast combined lifting tool disclosed by the invention is reasonable in structure, suitable for site lifting, heavy transferring and height-ascending assistance and especially suitable for electricity maintenance.

Description

technical field [0001] The invention relates to a fast combined hoisting tool for a power system. Background technique [0002] In the daily work of the power system, it is often necessary to conduct electrification experiments on various power equipment and tools or use electric tools for maintenance. At this time, an AC power supply is required. There are two main ways to obtain AC power, one is the power supply on the on-site power supply equipment, and the other is the generator set. Since the maintenance work in the field is usually done with power cut off, very long cables need to be laid, which is neither convenient nor safe. Even if there is occasional live work on site, not only climbing tools, such as ladders, etc. are needed to obtain electricity on site, but it will also have an adverse effect on electricity metering and electricity safety. Therefore, when using an AC power source for operations in the field, it is generally necessary to carry small and medium-...

AI Technical Summary

Problems solved by technology

[0003] Due to the heavy weight of small and medium-sized equipment such as generator sets, a three-phase diesel generator weighs about one ton, and generally requires 5 or 6 people to lift it up. Therefore, it should be stored outdoors or in a warehouse, moved, and unloaded, transported, and loaded in the field. are very inconvenient

The cost of buying a forklift is too high (about 100,000 yuan per set), and the cost of renting a crane is too high. It is impossible to lift it manually, and there are great risk factors, which may easily cause crushing, crushing and smashing injuries to the staff.

When moving small and medium-sized equipment such as generator sets, there are three operation methods: 1. Rent a crane for loading, and then use the crane to unload the truck when it is used up. The crane hoisting takes about 40 minutes to an hour (including dispatching vehicles and arrival time), It is a waste of time and cost, and it is necessary to reserve a crane in advance, which seriously affects the work progress

2. To buy a forklift, a forklift is about 100,000 yuan, which is relatively expensive, and the forklift cannot be dragged to the field operation site by a maintenance vehicle, so we can only arrange another driver to drive the forklift, which is very uneconomical

Because the generator storage location is still some distance away from the maintenance workshop, it is very cumbersome and troublesome to unload the generator in the same way after use.

This method is only suitable for transfer within the company, not for field work

[0004] In addition, when the power system is maintained in the field, generally only ladders can be carried for climbing, so ladders have become a must for power maintenance vehicles

At present, the ladder on the electric maintenance vehicle is an ordinary folding structure, and has no other purpose except electric climbing, so the function is relatively simple
