Description

A small hoisting machine fixed on the channel steel frame

Technical field:

The invention relates to a small-sized hoisting machine fixed on a channel steel structure, which is widely used in the upper and lower hoisting equipment fixed on the channel steel structure, and belongs to the field technical field of substation maintenance.

Background technique:

With the continuous development of power grid intelligence and automation, the expansion, transformation and maintenance of substations are increasing. In the construction of substation expansion and renovation projects, it is necessary to move and install a large number of heavy equipment, and a large part of these equipment are fixed on high-altitude structures, such as current transformers, voltage transformers and other equipment. Hoisting operation, but because many of the above equipment are installed indoors, the space is limited, lack of support points and other conditions, it is impossible to use large machinery, and the operation is difficult. The traditional operation method is to hang the manual upside-down chain on a firm support point, or build a bracket indoors, and hoist the equipment on the bracket with the upside-down chain. This method is not only time-consuming and a waste of manpower, but also has certain safety risks and is likely to cause safety accidents.

Invention content:

The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a simple structure, convenient manufacture, wide application range, labor saving, time saving, labor intensity reduction, efficiency improvement, high safety factor, and low manufacturing cost. A small hoist on a steel frame.

The purpose of the present invention can be achieved through the following measures: a small hoisting machine fixed on the channel steel frame, characterized in that it includes a lower iron plate at the bottom, an upper iron plate at the bottom, and the lower iron plate at the bottom and the upper iron plate at the bottom respectively There are corresponding bolt connection holes, the upper iron plate at the bottom is connected to the lower column, two iron plates are connected between the two sides of the lower column and the upper iron plate at the bottom, the lower end of the upper column is inserted into the lower column, and the upper end of the upper column is connected There are horizontal rods and oblique rods, the first support rod is connected between the upper column and the horizontal rod, the second support rod is connected between the upper column and the oblique rod, the third support rod is connected between the horizontal rod and the oblique rod, and the upper end of the oblique rod Connect the pulley, connect the small electric hoist under the horizontal rod, connect one end of the wire rope on the small electric hoist, pass the wire rope through the pulley, and connect the hook at the end of the wire rope.

Compared with the prior art, the present invention can produce the following positive effects: the present invention can be fixed on the channel steel structure, and the hoisting of the upper and lower equipment is controlled by the controller of the small electric hoist, which avoids potential safety hazards, saves labor, saves time, and reduces Labor intensity. which has:

1. Simple structure and convenient manufacture. The lower part is fixed on the channel steel structure, and the equipment is hoisted up and down by the controller in the distance.

2. Wide range of application. Applicable to all channel steel structure up and down hoisting equipment.

3. High maintenance efficiency. It can ensure safety, reduce test time, save labor and reduce labor intensity.

4. The production cost is low. The trolley can be used to transport equipment up and down with a channel steel structure, and has promotional value.
