[0029] The following will combine Figure 1-4 This application provides a detailed description of a portable GIS equipment maintenance device according to its embodiments. It is important to note that the following embodiments are merely illustrative and do not constitute a limitation thereof.

[0030] Example 1:

[0031] See Figure 1-4As shown, a mobile GIS equipment maintenance device includes: a gantry frame 1, a crane 2, and a mobile support unit. The gantry frame is U-shaped. The crane is located at the top of the gantry frame. Two mobile support units are respectively located at the bottom of both sides of the gantry frame for moving and supporting the gantry frame. Each mobile support unit includes: a base plate 3, a mounting plate damping unit, and a tie rod support unit. The base plate is fixedly connected to the bottom of both sides of the gantry frame. The mounting plate damping unit is rotatably connected to the base plate. The tie rod support unit is rotatably connected to the mounting plate damping unit and is used to pull the mounting plate damping unit and support the base plate.

[0032] In some embodiments, the mounting plate damping unit includes: a mounting plate 7, a rotating shaft 4, a bearing 5, and a damping spring 6. The rotating shaft is inserted through and connected to the base plate. A bearing is sleeved on the surface of the rotating shaft at the insertion point on the base plate. The bottom of the rotating shaft is configured as a telescopic rod. The damping spring is sleeved on the outside of the telescopic rod. The bottom end of the rotating shaft is fixedly connected to the mounting plate. Here, the bottom of the rotating shaft is configured as a telescopic rod to cooperate with the damping spring to mainly play the role of damping.

[0033] The bottom of the mounting plate is provided with a first steering wheel 8; both sides of the mounting plate are provided with mounting holes, and a limit block 17 is inserted into the mounting hole. One end of the limit block is fixedly connected to a return spring 18, and one end of the return spring is fixedly connected to the mounting hole.

[0034] In some embodiments, the tie rod support unit includes: a telescopic tie rod 10, a handle 11, a rotating column 12, a support frame 13, a limiting plate 14, and a bolt 15. The two telescopic tie rods are bent in the middle. The telescopic tie rod includes a horizontal section and an inclined section. The horizontal section is configured as a telescopic rod.

[0035] In some embodiments, extension plates 20 are provided on both sides of the horizontal section of the two telescopic rods, and the extension plates are flush with the lower surface of the telescopic rods. Support rods 9 are provided on both sides of one end of the base plate, and second steering wheels 21 are fixedly connected to the bottom of the two support rods. The bottom surfaces of the first steering wheel and the two second steering wheels are flush.

[0036] Both telescopic rods have rotating columns rotatably inserted into their inclined sections. One end of each rotating column is fixedly connected to a mounting plate, and the other end of each telescopic rod is connected to the same support frame. A limiting plate is movably inserted inside the support frame, and a bolt is rotatably inserted into the bottom of the limiting plate. The bolt is threadedly connected to the support frame. A fixing groove 16 matching the limiting plate is provided at the bottom of the base plate, and a limiting groove 19 that mates with the limiting block is provided on the surface of each telescopic rod's inclined section. When the limiting plate is placed in the fixing groove, the horizontal section of the telescopic rod is in a horizontal state. One end of each horizontal section of the two telescopic rods is connected to the same handle.

[0037] Before moving the maintenance device, the two extended telescopic rods 10 can be rotated to lengthen the horizontal section of the telescopic rod, i.e., the bottom end is stretched and lengthened, achieving a convenient and labor-saving effect. The mounting plate 7 is pulled by the handle and the extended telescopic rods 10, thereby moving the entire maintenance device. After the maintenance device is pulled into position, the handle 11 is pushed to retract the two extended telescopic rods 10. Then, the handle 11 can be pushed down to cause the two telescopic rods 10 to deflect around the rotating column 12 to the desired position. Figure 1 As shown, after the bottom of the retractable parts of the two telescopic rods 10 contact the ground, the bottom surface of the telescopic rods is at the same height as the bottom of the first steering wheel 8, and the support frame 13 then fits against the bottom surface of the mounting plate 7. Subsequently, the bolts 15 are rotated so that the limiting plate 14 is inserted into the fixing groove 16 from the top of the support frame 13 upwards.

[0038] When the crane 2 is working, it presses down as a whole, the support frame 13 supports the base plate 3, and the two bent telescopic rods 10 support the ground. This increases the support strength of the maintenance device for the support frame 13 and the base plate 3. After the telescopic rods 10 come into contact with the ground, the friction increases, preventing the maintenance device from moving. At the same time, the extension plate 20 increases the contact area between the telescopic rods 10 and the ground, making the bottom of the first steering wheel 8 more stable, thereby increasing the support strength of the maintenance device.

[0039] When movement is required, the two telescopic rods 10 on one side can be rotated to the position of the limiting block 17. The limiting block 17 is squeezed and retracted into the mounting hole of the mounting plate 7, compressing the return spring. When the limiting groove 19 and the limiting block 17 are aligned, the return spring 18 pushes the limiting block 17 into the limiting groove 19, which restricts the telescopic rods 10, making it easy to move by pulling the device through the handle 11 on one side, while the two telescopic rods 10 and the handle on the other side rub against the ground.

[0040] The telescopic rod 10 can fix the distance between the mounting plate 7 and the base plate 3, and prevent the shock-absorbing springs 6 on both sides from becoming uneven at the top of the frame 1 due to unstable force during maintenance.

[0041] The above description is merely a preferred embodiment of the present invention and is intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
