Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric power industry, especially to a carrying system of box transformer equipment. BACKGROUND

[0002] In modern power systems, the stability and flexibility of power supply are important foundations for social and economic development. With the acceleration of urbanization and the widespread use of new energy, traditional fixed substations gradually fail to meet the increasingly complex power demand. This has prompted the birth and development of mobile substations, which are driven by innovation.

[0003] With the expansion of city size and population increase, urban construction projects such as high-rise buildings, transportation hubs, and commercial centers are constantly emerging. These projects usually require temporary but stable power supply during the construction phase. Fixed substations have long construction periods and high costs, which are not suitable for frequent temporary needs. Natural disasters such as typhoons, earthquakes, and floods occur every year, causing serious damage to the power grid and leading to widespread power outages. In such cases, mobile substations can be quickly deployed to disaster areas to restore power supply and reduce the impact of disasters on social life. After the 2011 Japan earthquake, mobile substations were quickly deployed to disaster areas to ensure the smooth progress of disaster relief work. Wind and solar energy generation has intermittent and unstable characteristics, and traditional power grids are difficult to effectively integrate these energies. Mobile substations can serve as a buffer and adjustment means to stabilize the output of new energy generation and optimize the power system. In Germany's Energiewende (energy transition) plan, mobile substations have become an important tool for integrating new energy into the grid. Today, the design and development of mobile substations face many technical challenges. For example, modular design, efficient energy conversion, automation and intelligence, and environmental adaptability need special consideration.

[0004] In addition, the box transformer equipment needs to be transported to some areas with low site requirements by a flat car, but still needs to be unloaded by a crane to place it in the designated position. For some remote mountainous areas, the cost of a crane vehicle and manpower is also not small. UTILITY MODEL CONTENT

[0005] To overcome the shortcomings of the prior art, the utility model provides a carrying system of prying equipment substation equipment, which does not need to be equipped with a crane, and does not need to consider the crane hoisting space during carrying and placing.

[0006] The utility model is implemented through the following technical solutions:

[0007] A kind of prying equipment substation equipment carrying system, the system includes flat car, winch, flat car end drum shaft, flat car inner drum shaft, prying equipment and steel wire rope;The front end of the flat car is installed with winch The middle end of the flat car is installed with a flat car inner drum shaft, and the flat car inner drum shaft is embedded in the platform of the flat car;The end of the flat car is installed with a flat car end drum shaft, and the lifting lug of the prying equipment is connected with the winch by steel wire rope.

[0008] Specifically, the flat car end is provided with a drum shaft, which is used for loading or unloading the prying equipment without causing wear of the prying equipment.

[0009] Specifically, the base structure of the prying equipment is arc-shaped front and rear, which does not cause wear of the prying equipment when loading or unloading the prying equipment.

[0010] Specifically, the platform of the flat car is provided with a flat car inner drum shaft, so that the prying equipment is not worn when being dragged on the platform of the flat car.

[0011] The beneficial effects of the present application are as follows:

[0012] The carrying and placing equipment does not need to be equipped with a crane, and when carrying and placing, the problem of crane hoisting space (such as an open space on the top of the hoisting equipment) does not need to be considered, the space requirement of the hoisting equipment is also reduced, and most importantly, the equipment of the crane is reduced, the manpower, vehicle rental fee and the like are reduced, and the efficiency is greatly improved.
