[0032] SUMMARY

[0033] In the field of electric power, the installation, maintenance and other operations of electric power equipment usually need to be disassembled, and the disassembly process of some large electrical equipment usually needs to be assisted by auxiliary equipment, such as large vertical column voltage transformers, current transformers and the like of 35KV, 110KV voltage levels. Due to the heavy weight and large volume of the components, large cranes and the like are usually used for hoisting and transporting to assist disassembly. However, there are many live equipment (such as busbars, circuit breakers and the like) around the installation area of the above-mentioned electrical equipment, and the use of large cranes for disassembly has low efficiency and high cost. Moreover, due to the large operating range of the crane, other equipment may be accidentally touched during operation, causing unnecessary losses and requiring higher operating experience of the operator. In the area where electrical equipment is concentrated (such as the busbar equipment area), in order to ensure safe operation, a large range of power supply needs to be stopped, but power outage will affect the normal power consumption of users, causing certain economic losses to users. However, the longer the power outage operation time, the greater the loss, and it is required to quickly complete the disassembly and assembly of electrical equipment and restore power supply as soon as possible, and the traditional disassembly and assembly method cannot meet the above requirements.

[0034] Some embodiments of an electrical equipment auxiliary disassembly and assembly device in the technical solutions of the present application are provided below.

[0039] In a further embodiment of the application, as shown in Figures 1 to 3 The driving assembly 3 includes a first oil cylinder 31, a hydraulic driving mechanism 32 and a horizontal driving mechanism 33. The first oil cylinder 31 is arranged on one side of the lifting frame 21 and extends along the lifting frame 21 in the height direction, and the piston end of the first oil cylinder 31 is connected with the vertical sliding piece 212 to drive the vertical sliding piece 212 to move up and down in the height direction through the extension and retraction of the piston end of the first oil cylinder 31. The hydraulic driving mechanism 32 is arranged in the vehicle body assembly 1 and is in hydraulic connection with the first oil cylinder 31 to supply hydraulic oil to the first oil cylinder 31 and drive the first oil cylinder 31 to extend and retract. The horizontal driving mechanism 33 is also arranged in the vehicle body assembly 1, and the horizontal driving mechanism 33 is in transmission connection with the lifting frame 21 to provide power to the lifting frame 21 and drive the lifting frame 21 to move horizontally relative to the vehicle body assembly 1.

[0042] In further embodiments of the application, as shown in Figure 1 and Figure 3 , the electrical equipment auxiliary disassembly and assembly device 100 further comprises a first limiter 41, a second limiter 42, and a drive controller 43. The drive controller 43 is arranged on the hydraulic driving mechanism 32 and is in communication connection with the hydraulic driving mechanism 32, and the drive controller 43 can acquire state information of the hydraulic driving mechanism 32.

According to the use requirement, a first position limiter 41 can also be arranged at the bottom of the lifting frame body 21 to limit the position of the vertical sliding part 212 during the descending process. Specifically, the first position limiter 41 can be a limit switch, a proximity switch or other form of position limiting device.

[0044] Similarly, the second position limiter 42 is arranged in the vehicle body assembly 1 and located at the limit position of the horizontal movement stroke of the lifting frame body 21, for sensing the horizontal position of the lifting frame body 21 and generating corresponding second sensing information. The drive controller 43 is in communication connection with the second position limiter 42 and can determine the horizontal position of the lifting frame body 21 through the second sensing information; when the lifting frame body 21 moves to the limit position of the horizontal movement stroke, the drive controller 43 controls the hydraulic drive mechanism 32 to perform corresponding control operation, so that the lifting frame body 21 stops horizontal movement, thereby preventing the lifting frame body 21 from exceeding the limit position and achieving horizontal position limiting. Specifically, the second position limiter 42 can be a limit switch, a proximity switch or other form of position limiting device. The number of the second position limiter 42 can be arranged according to the horizontal movement range of the lifting frame body 21; for example, when the lifting frame body 21 can only move linearly, one first position limiter 41 can be arranged at each end of the horizontal movement stroke; when the lifting frame body 21 can move in other directions on the horizontal plane, multiple first position limiters 41 can be arranged in different directions.
