By providing the lifting groove 301 and the lifting rod 303, it is convenient to adjust the use position of the pull rod 304.

[0027] Please refer to Figure 4 , the lifting mechanism 2 includes a limit rod 201, a limit plate 202, a support connecting plate 203, a support plate 204 and a lifting electric cylinder 205. The limit rod 201 is fixedly connected to the upper surface of the second cross frame 103, the limit plate 202 is slidably lifted on the limit rod 201, the support connecting plate 203 is fixedly connected to one side of the limit plate 202, the support plate 204 is fixedly connected to the top surface of the support connecting plate 203, the lifting electric cylinder 205 is fixedly connected to the upper surface of the bottom plate 105, the top output end of the lifting electric cylinder 205 is fixedly connected to the bottom surface of the support plate 204, and the limit rod 201 is fixedly connected between the first cross frame 102 and the second cross frame 103.

[0028] By providing the limit rod 201, the limit plate 202 and the support connecting plate 203, it is convenient to provide auxiliary support for the support plate 204 and keep it stable during the lifting process of the support plate 204. By providing the lifting electric cylinder 205, it is convenient to control the lifting of the support plate 204 and the test equipment main body 106.

[0029] Working principle: When a test device for power commissioning is in use, in the initial state, first, the main arm 1 and the auxiliary arm 104 are spliced using the first cross-frame 102 and the second cross-frame 103. A moving wheel 101 is provided at the bottom of the main arm 1, and the test device main body 106 is installed on the top of the lifting mechanism 2 above the bottom plate 105, so as to facilitate the movement of the test device main body 106 and adjust its use height at the same time. At the same time, a lifting rod 303 and a pull rod 304 are lifted in the lifting groove 301 opened at the top of the main arm 1. The U-shaped plate 305 connected to the side wall of the lifting rod 303 penetrates the side groove 302 and bends outward, and the outer end of the U-shaped plate 305 is connected with a bolt 307 and a clamping plate 308, so as to facilitate the adjustment of the use height of the pull rod 304.

[0030] When it is necessary to adjust the use height of the pull rod 304 according to the height of the tester, first reverse the bolt 307 and move it outward under the action of the screw hole 306 to drive the clamping plate 308 to release the contact with the main arm 1. At this time, the lifting rod 303 is in the unlocked state, and the pull rod 304 can be adjusted by holding it and moving it up and down. During the movement of the pull rod 304, the two ends of the lifting rod 303 also rise and fall inside the lifting groove 301 and drive the U-shaped plate 305 to move and adjust inside the side groove 302. After the position of the pull rod 304 is adjusted, rotate the bolt 307 forward so that it moves inward under the action of the screw hole 306 and pushes the clamping plate 308 to contact the surface of the main arm 1 to clamp and fix the lifting rod 303. This device is convenient for adjusting the use height of the pull rod 304 according to the height of the tester.

[0031] When it is necessary to adjust the use height of the test device main body 106, first control the lifting electric cylinder 205 to push out its top end. The lifting electric cylinder 205 with the top end pushed out pushes the support plate 204 and the test device main body 106 above it to move up. During the upward movement of the support plate 204, the support connecting plate 203 and the limit plate 202 will also move up. Since the limit plate 202 is slidably sleeved on the limit rod 201, when the support plate 204 moves up, the limit rod 201 and the limit plate 202 will use the support connecting plate 203 to support the support plate 204 to prevent it from tilting until the support plate 204 is adjusted to a height suitable for the tester for the test device main body 106. This device is convenient for adjusting the use height of the test device main body 106.
