[0027] Specific implementation method of prefabricated substation self-loading and unloading device:

[0028] Install the hydraulic station 6 on the matching hydraulic support 3. This solution adopts a matching installation method of a set of hydraulic stations 6 and a set of hydraulic columns. Install the connected hydraulic supports 3 (the number and installation positions of the hydraulic columns can be arranged according to the specific pre-installed substation size, weight, center of gravity position and other factors) on the support arm 2, combine the support arm 2 with the rotating shaft 102 on the mounting plate 101, and connect the battery pack and the control box 5 by wiring. Connect the control box 5 to the hydraulic station 6 through cables to control the operation of the hydraulic station 6 and realize the telescopic operation of the hydraulic support 3.

[0029] Taking the prefabricated substation cabin composed of 40.5kV high-voltage cabinets as an example, further explanation is given:

[0030] The shell 1 (cabin) of a prefabricated substation in a certain project is 9 meters long and 3.5 meters wide. The on-site construction site is limited. The installation range of this station is only about 15 meters long and 8 meters wide. After the prefabricated substation transport vehicle enters, the lifting equipment cannot enter. After adopting this device, during the loading operation, the hydraulic support 3 in the self-loading and unloading device of the prefabricated substation is unfolded from the folded position to the working position, that is, Figure 3 Transformed into Figure 1 mode, now remove the connecting bolts of the fixing plate 1 404 and the fixing plate 2 405, and rotate the support arm 2 so that the support arm 2 extends out of the housing 1 through rotation, and fix the support arm 2 through the cooperation of the positioning plate 403 with the fixing block 1 401 and the fixing block 2 402, so that the support arm 2 cannot rotate;

[0031] Then, the hydraulic station 6 is controlled by the control box 5 to extend the telescopic end of the hydraulic prop 3 until the bottom of the prefabricated substation shell 1 reaches a height of 1.3 meters to 1.5 meters from the ground (the chassis of the transport vehicle is generally 1.1 meters). When the bottom surface of the cabin is 20-30 centimeters higher than the vehicle undercarriage, the transport vehicle tows the chassis vehicle in reverse and drives under the shell 1. When the shell 1 is flush with the rear of the vehicle and the shell 1 is completely above the chassis of the transport vehicle, the hydraulic prop 3 is controlled to descend and the shell 1 is placed stably on the vehicle chassis. Then the hydraulic prop 3 is retracted and re-fixed by the fixing plate 1 404 and the fixing plate 2 405 to reduce the space occupied.

[0032] After arriving at the site, the vehicle reverses into the placement area of ​​the pre-installed substation shell 1, raises the hydraulic support 3 through the control box 5, and after the bottom surface height of the shell 1 reaches 1.3 meters, the vehicle drives away and controls the hydraulic support 3 to lower the shell 1. At this time, the self-loading and unloading work of the pre-installed substation is completed.

[0033] The utility model has a compact structure and flexible application, and can be applied to the self-loading and self-unloading of various types of cabins in a wide area. In particular, when the space on the substation site is narrow and there are live equipment above and around the working area, and a crane cannot be used, the device can perfectly solve this problem. At the same time, it solves the dependence of the prefabricated substation on lifting and hoisting equipment for loading and unloading. Through the realization of automatic loading and unloading operations, the efficiency of loading and unloading operations is greatly improved, and labor costs are saved. At the same time, the rope operators and hook operators in traditional lifting operations are eliminated, and the operators can stay away from the mechanical operating range, making loading and unloading operations safer.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
