A handle is fixed on the front of the hinged door. A top plate 2 is fixed on the top of the substation 1. The top of the top plate 2 has an inherent mounting component. The mounting component includes two fixed plates 3, two sliding plates 4 and four fixing pins 5. The sliding plate 4 is slidably connected to the fixed plate 3. The fixed plate 3 can slide on the outer surface of the sliding plate 4 to adjust the position of the fixed plate 3.

[0023] In addition, the fixed plate 3 is fixed to the top plate 2, and the fixed plate 3 is slidably connected with the fixing pin 5 inserted into the sliding plate 4. The set fixing pin 5 is inserted into the inside of the sliding plate 4 to fix the fixed plate 3. The hook 6, the fixing buckle 7 and the fixing block 801 are all fixed to the fixed plate 3. The front and rear sides of the fixed plate 3 are provided with a plurality of through holes that are compatible with the fixing pin 5. The multiple through holes are set so that after the fixed plate 3 moves, the fixing pin 5 can still be plugged into the sliding plate 4. Four hooks 6 are fixed to the top of the installation component, and four fixing buckles 7 are fixed to the bottom of the installation component. The setting of the fixing buckle 7 allows the installation component to be fixed to the top plate 2.

[0024] Furthermore, four tightening components 8 are fixed on the top of the installation component, connecting hooks 9 are fixed on the bottom of the tightening components 8, and steel wire ropes 10 are fixed inside the two front connecting hooks 9 and inside the two back connecting hooks 9. The installed steel wire ropes 10 can lift the bottom of the substation 1, thereby making the lifting more stable, and the tightening components 8 are used to put the steel wire ropes 10 into a taut state.

[0025] In general, the fixing plate 3 can slide on the outer surface of the sliding plate 4, so that substations 1 of different sizes can be fixed, which effectively improves the overall practicality.

[0026] See also Figure 3 The tightening assembly 8 in this embodiment includes a winding rod 802, a connecting rope 803, a control block 804, a positioning assembly and two fixed blocks 801. The fixed block 801 is fixed to the mounting assembly. The interior of the fixed block 801 is threadedly connected to the winding rod 802. The winding rod 802 is a threaded rod. The interior of the fixed block 801 is provided with a threaded hole that is compatible with the threaded rod. Through the threaded connection, when the winding rod 802 rotates, it will move at the same time. One end of the connecting rope 803 is fixed to the winding rod 802, so that the connecting rope 803 can be wound around the outer surface of the winding rod 802.

[0027] In addition, one end of the connecting rope 803 away from the winding rod 802 is fixed to the connecting hook 9, the control block 804 is fixed to the winding rod 802, and the outer surface of the control block 804 is fixed to the positioning assembly.

A plurality of positioning holes are provided inside the positioning block 805. The positioning holes are arranged so that after the positioning block 805 rotates, the positioning rod 806 can still be slidably connected to the positioning block 805 and then plugged into the fixed plate 3. The wire rope 10 is a high-strength lifting rope.

[0028] In general, by rotating the winding rod 802, the connecting rope 803 can be wound around the outer surface of the winding rod 802, and then the connecting hook 9 is pulled to move, so that the wire rope 10 is tightened, so that substations 1 of different sizes can be lifted, effectively improving the overall practicality.

[0029] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0030] The working principle of the above embodiment is:

[0031] By pulling out the fixing pin 5, the fixing plate 3 can be made to slide on the outer surface of the sliding plate 4, so that the fixing plate 3 can be adjusted according to the size of the substation 1, so that the fixing buckle 7 can be buckled on the bottom of the top plate 2. At this time, the fixing plate 3 can be fixed by reinserting the fixing pin 5. After the wire rope 10 is fixed to the connecting hook 9, the winding rod 802 can be rotated by rotating the control block 804, and the winding rod 802 will move due to the extrusion of the thread, so that the connecting rope 803 is wound around the outer surface of the winding rod 802, and then the connecting hook 9 is pulled to complete the adjustment of the position of the connecting hook 9, so that the wire rope 10 is in a taut state, and the positioning rod 806 is inserted into the interior of the fixing plate 3 to complete the fixation of the positioning block 805 and the control block 804, thereby effectively ensuring the stability of the fixation, and finally the lifting hook of the crane is fixed to the hook 6. The overall structure is simple, and substations 1 of different sizes can be fixed, making the overall structure more practical.
