Description

Lifting device for electrical equipment

Technical field: The utility model relates to a lifting device, in particular to a lifting device used for hoisting electrical equipment during maintenance of a power transformation and distribution system.

Background technology: In the power transformation and distribution system, in order to ensure the reliability of power supply, electrical equipment such as isolating switches and lightning arresters must be regularly overhauled and maintained. During the overhaul and maintenance process, equipment replacement is bound to be involved. In the past, the replacement of isolating switches or arresters has always been carried out by cranes or poles. Due to the narrow working space on site, it is not suitable for large-scale lifting equipment, resulting in difficult lifting work, long power outages, and low work efficiency (it takes 3.5 hours to hoist a set of isolating switches with a crane, and 6 hours to hoist with a pole). Moreover, the traditional hoisting method lacks operational flexibility and has various complicated requirements in the hoisting process, which leads to too complicated work links in actual production and increases unsafe factors in the work.

Summary of the invention: The purpose of this utility model is to provide a lifting device for electrical equipment, mainly to solve the problem that the working space on site is narrow, the existing lifting equipment is not suitable, the lifting work is difficult, the power failure time is long, the work efficiency is low, and there are problems The question of safety factors.

The scheme of the present utility model is as follows; this utility model comprises connecting bolt, electric hoist, fixed base, and it is by arranging rotatable L-shaped bracket, is provided with hook on the beam of L-shaped bracket, connects and fixes an electric hoist through hook, And it is realized by setting a fixed base at the bottom of the L-shaped bracket.

Beneficial effects of the utility model: due to the above-mentioned structure, the utility model can fix the whole device on the basic frame of the electrical equipment to be replaced through the fixed base, and use the relatively narrow working space to smoothly lift within the range of 360°, and at the same time It has the advantages of reasonable structural design, convenient and flexible operation, stable and reliable performance, significantly shortened working time, effectively improved work efficiency, economical and practical, and suitable for promotion in the industry.

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

Specific embodiments: the electrical equipment lifting device shown in Figure 1 is composed of a crossbeam and a longitudinal beam to form an L-shaped support 1, the bottom of the L-shaped support 1, that is, the bottom of the longitudinal beam, is provided with a fixed base 2, and the fixed base 2 is provided with an inner sleeve 3. The inner sleeve 3 is placed in the longitudinal beam of the L-shaped bracket 1, so that the L-shaped bracket 1 can rotate 360° along the inner sleeve 3. In order to increase the mechanical strength, reinforcing ribs are provided on the L-shaped bracket 1 . There is a hook 4 on the crossbeam of the L-shaped bracket 1, and the electric hoist 5 is connected through the hook 4. When the device is working, the device is fixed on the isolation switch or the lightning arrester frame through the connecting bolt 6 on the fixed base 2. Electrical equipment such as isolating switch or lightning arrester is hoisted to the frame height through electric hoist 5, and the L-shaped support 1 is rotated to lightly place electrical equipment such as isolating switch or lightning arrester on the structure. The device can work in a narrow space where a crane cannot enter, is convenient and flexible to use, can save manpower, and is safe and reliable.
