Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present utility model: an industrial high and low voltage frequency converter maintenance and test platform, including a maintenance table 1. Both the front and rear ends of the inner wall of the maintenance table 1 are fixedly connected with a plurality of rollers 3. Both the front and rear sides of the middle part of the top wall of the maintenance table 1 are fixedly connected with load-bearing vertical plates 4. A plurality of rolling beads 5 are rotatably connected to the top walls of the two load-bearing vertical plates 4 at equal intervals.

The right side of the outer wall of the extended worm 6 is meshed and connected with a turbine 7. The rear end of the turbine 7 is fixedly connected with a threaded rod 8. The right side of the top wall of the maintenance table 1 is fixedly connected with a sliding plate 9. The outer wall of the threaded rod 8 is threadedly connected with two moving support rods 10. The right ends of the two moving support rods 10 are slidably connected to the inner wall of the sliding plate 9. A moving plate 11 is slidably connected between the two adjacent moving support rods 10. The front side of the moving plate 11 is fixedly connected with a telescopic rod 12. A maintenance camera 13 is fixedly installed on the top wall of the moving plate 11. A hoisting mechanism 2 is arranged on the front and rear sides of the top wall of the maintenance table 1;

[0033] Specifically, on the maintenance table 1, the rollers 3 are used to easily adjust the position of the frequency converter to be maintained. The load-bearing vertical plates 4 on the top of the maintenance table 1 provide stable support for the frequency converter through the rolling beads 5, while reducing friction. By rotating the extended worm 6 and the turbine 7, the threaded rod 8 is driven to rotate. The rotation of the threaded rod 8 causes the two moving support rods 10 to move horizontally on the inner wall of the sliding plate 9. According to the size and shape of the frequency converter, the position of the moving plate 11 between the moving support rods 10 is adjusted, and the shooting angle and position are adjusted as the moving plate 11 moves, realizing the full-range monitoring and recording of the frequency converter maintenance process, and improving the maintenance efficiency and accuracy.

[0034] Referring to Figure 1 、 Figure 2 and Figure 4 , the hoisting mechanism 2 includes a plurality of support columns 201. The top ends of the plurality of support columns 201 are fixedly connected with a top plate 202. The middle part of the bottom wall of the top plate 202 is fixedly connected with an I-shaped track 203. Electric wheels 204 are rotatably connected to the left and right sides of the I-shaped track 203. The bottom ends of the electric wheels 204 are fixedly connected with elevators 205. The middle part of the bottom end of the elevator 205 is slidably connected with a lifting hook 206;

[0035] Specifically, the hoisting mechanism 2 is located at the top of the maintenance platform 1. To lift and fix the inverter to be repaired so that maintenance personnel can easily carry out operations, the support column 201 connected to the maintenance platform 1 can stably support the entire hoisting mechanism 2. The top of the support column 201 is equipped with a top plate 202 through a fixed connection method. The top plate 202 serves as the foundation for load-bearing and connection. In the middle of the bottom wall, an I-beam track 203 is installed. Electric wheels 204 are provided on both the left and right sides of the I-beam track 203, and can be controlled to rotate freely along the track by operating the operation button 15. A lift 205 is fixedly connected to the bottom of each electric wheel 204 for lifting and lowering the lifting hook 206. During the maintenance process, the maintenance personnel operate the electric wheel 204 by operating the operation button 15, so that the lift 205 moves along the I-beam track 203 to a suitable position, connects the lifting hook 206 to the lifting point on the inverter, and operates the control system again to make the lifting hook 206 slowly rise, thereby lifting the inverter smoothly and suspending it at a certain height. Then, the inverter can be overhauled and maintained comprehensively under safe conditions. The entire hoisting process is efficient and stable, greatly improving the efficiency and safety of the maintenance work.

[0036] Refer to Figure 1 and Figure 2 , in the middle of the front side of the maintenance platform 1, an operation console 14 is fixedly connected. A plurality of operation buttons 15 are fixedly installed on the top of the operation console 14; anti-slip pads 17 are fixedly connected to the four corners of the bottom wall of the maintenance platform 1; a support frame 18 is fixedly connected to the front side of the top wall of the maintenance platform 1, and a plurality of spirit levels 19 are fixedly installed on the inner wall of the support frame 18;

[0037] Specifically, the operation console 14 provides an intuitive operation interface for maintenance personnel. The operation buttons 15 on its top can control the electric wheels 204, the lifts 205, and the inspection camera 13, and can easily perform the test process. The columns 16 at the bottom of the maintenance platform 1 not only stably support the entire platform, but also ensure the stability of the platform during operation through the anti-slip pads 17 at their bottoms. The support frame 18 is used to install the spirit levels 19 inside it, and the spirit levels 19 are used to detect whether the platform is in a horizontal state.

[0038] Refer to Figure 1 , Figure 2 and Figure 5, a limiting triangular block 20 is fixedly connected to the middle of the top wall of the maintenance table 1, the front end of the turbine 7 is rotatably connected to the inner wall of the limiting triangular block 20, a protective shell 21 is fixedly connected to the bottom end of the left side of the inner wall of the maintenance table 1, and a lengthened worm 6 and a turbine 7 are arranged on the inner wall of the protective shell 21; a chute 22 is opened on the inner wall of the front load-bearing vertical plate 4, a limiting roller piece 23 is rotatably connected to the outer wall of the telescopic rod 12, and the limiting roller piece 23 is rotatably connected to the inner wall of the chute 22; a handle 24 is fixedly connected to the top end of the lengthened worm 6 and the front end of the telescopic rod 12 respectively, and a plurality of anti-slip strips 25 are fixedly connected to the outer walls of the two handles 24;

[0039] Specifically, the limiting triangular block 20 provides stable support and limitation for the turbine 7 to ensure that the turbine 7 will not deviate from the track or shake during rotation. The protective shell 21 outside the lengthened worm 6 and the turbine 7 can prevent damage to body parts during their rotation. The telescopic rod 12 slides in the chute 22 of the load-bearing vertical plate 4 through the limiting roller piece 23, can be adjusted in length according to needs, and ensures the smoothness and accuracy of the sliding process through the limiting roller piece 23. The handles 24 on the lengthened worm 6 and the turbine 7 are convenient for maintenance personnel to operate. At the same time, the anti-slip strips 25 on the outer walls of the handles 24 improve the firmness of grasping and prevent operation errors caused by slippery hands.

[0040] Working principle: On the maintenance table 1, the position of the inverter to be repaired is easily adjusted by using the roller 3. The load-bearing vertical plate 4 on the top of the maintenance table 1 provides stable support for the inverter through the rolling beads 5, and at the same time reduces friction. By rotating the lengthened worm 6 and the turbine 7, the threaded rod 8 is driven to rotate. The rotation of the threaded rod 8 causes the two moving support rods 10 to move horizontally on the inner wall of the sliding plate 9. According to the size and shape of the inverter, the position of the moving plate 11 between the moving support rods 10 is adjusted, and the shooting angle and position are adjusted as the moving plate 11 moves.

[0041] And the lifting mechanism 2 is located on the top of the maintenance table 1. In order to lift and fix the inverter to be repaired so that the maintenance personnel can easily carry out the operation, the support column 201 connected to the maintenance table 1 can stably support the entire lifting mechanism 2. Its top end is equipped with a top plate 202 by means of fixed connection. The top plate 202 serves as the basis for load-bearing and connection. An I-shaped track 203 is installed in the middle of the bottom wall. Electric wheels 204 are arranged on both the left and right sides of the I-shaped track 203 and can be controlled to rotate freely along the track by operating the operation button 15. A lift 205 is fixedly connected to the bottom of each electric wheel 204 for lifting and lowering the lifting hook 206. During the maintenance process, the maintenance personnel operate the electric wheel 204 by operating the operation button 15 to make the lift 205 move along the I-shaped track 203 to a suitable position, connect the lifting hook 206 to the lifting point on the inverter, and operate the control system again to make the lifting hook 206 slowly rise, so as to lift the inverter smoothly and hang it at a certain height.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
