[0023] Example 1:

[0024] Refer to Figure 1-2 As shown in the figure, a simulation on-site GCB test work platform includes a support platform 106. A plurality of support rods 105 are arranged on the lower side of the support platform 106. A height adjustment device is installed at the bottom of the support rod 105. The height adjustment device includes a base 101, a threaded rod 102, a threaded sleeve 103, a lifting plate 104 and a driving member 109. The threaded rod 102 is rotatably installed in the base 101. The lifting plate 104 is located at the upper end of the base 101. A threaded sleeve 103 is fixedly arranged on the lower side of the lifting plate 104. The threaded rod 102 is threadedly connected with the threaded sleeve 103. The driving member 109 is used to drive the lifting plate 104 to lift. The test equipment is installed on the support platform 106. The support rod 105 is used to support the support platform 106. The height adjustment device is used to adjust the height of the support platform 106, so as to adjust the height of the equipment installed on the support platform 106 and facilitate simulating the actual on-site environment.

[0025] Refer to Figure 2 As shown in the figure, the driving member 109 includes a turbine 110 and a worm 111. The turbine 110 is fixedly installed on the threaded rod 102. The two ends of the worm 111 are rotatably connected to the base 101. The worm 111 meshes with the turbine 110. And one end of the worm 111 extends out of the base 101 for rotating the worm 111. By rotating the end of the worm 111 that extends out of the base 101, the threaded rod 102 is driven to rotate. Since the threaded rod 102 is threadedly connected with the threaded sleeve 103 and the threaded sleeve 103 is fixedly installed on the lower side of the lifting plate 104, the rotation of the threaded rod 102 will drive the lifting plate 104 to lift.

[0026] Specifically, the rotation of the worm 111 can be manually turned by a wrench or driven by a motor.

[0027] Furthermore, the driving member 109 further includes a guide rod 112. The guide rod 112 is fixedly installed on the lower side of the lifting plate 104. The guide rod 112 slides downward and penetrates into the base 101. The lifting of the lifting plate 104 is guided by the guide rod 112, thereby improving the stability of the lifting plate 104 during lifting.

[0028] Specifically, a guide rod 112 is fixedly connected to each side of the threaded sleeve 103 on the lower side of the lifting plate 104 of each height adjustment device.

[0029] Refer to Figure 1, multiple support rods 105 are connected and fixed by diagonal braces 107. By setting the diagonal braces 107 to connect multiple support rods 105, the stability of the support platform 106 is improved.

[0030] Embodiment 2:

[0031] See Figure 3 、 4 , a standing platform 108 is installed on one side of the support platform 106, facilitating personnel to stand during operation.

[0032] Furthermore, a staircase is installed on one side of the support platform 106 where the standing platform 108 is located. An installation seat 205 is fixedly provided at the upper end of the staircase, and the installation seat 205 is connected to the support platform 106 by bolts. It is convenient for the staff to reach the standing platform 108 through the staircase, and the installation seat 205 is connected to the support platform 106 by bolts, facilitating the installation, fixation, and disassembly of the staircase and the support platform 106.

[0033] Even further, guardrails 203 are respectively arranged on both sides of the staircase and the standing platform 108, providing protection for the staff to pass through and preventing the staff from falling.

[0034] Specifically, the staircase includes installation rods 201 and treads 202. Two installation rods 201 are provided and are respectively located on both sides of multiple treads 202. The treads 202 are distributed in a stepped manner between the two installation rods 201. It is convenient for the staff to climb onto the standing platform 108 through the treads 202 to debug the equipment. The upper end of the installation rod 201 is installed with an installation seat 205, and part of the guardrail 203 is installed on the installation rod 201.

[0035] In addition, when adjusting the height of the support platform 106 through the height adjustment device, a support plate 206 is also padded at the lower end of the staircase. By increasing or decreasing the thickness of the support plate 206, the staircase can meet the installation requirements.

[0036] The working process or principle of the present utility model is as follows:

[0037] When using the simulated on-site GCB test working platform of the present utility model, the equipment is hoisted onto the support platform 106 and supported by the support rods 105. When the height of the equipment needs to be adjusted, the worm 111 is rotated to drive the worm wheel 110 to rotate. Then, the worm wheel 110 drives the threaded rod 102 to rotate, and the threaded rod 102 drives the threaded sleeve 103 to lift and lower, thereby driving the lifting plate 104 to lift and lower. Thus, the support platform 106 and the equipment are driven by the support rods 105 to lift and lower, realizing the adjustment of the height of the equipment and facilitating the simulation of the on-site environment.
