[0033] like Figure 3 and Figure 4As shown, the adjusting device 5 includes a fixing column 51, which is fixedly connected to the support frame 1. The inner wall of the fixing column 51 is threadedly connected with an adjusting screw 54, one end of the adjusting screw 54 is fixedly connected with a turning handle 55, and the other end of the adjusting screw 54 is rotatably connected with a first fixing plate 53. When the well control pressure test is carried out, the protective equipment is installed in the foundation pit. When the protective equipment needs to be repaired, the support frame 1 is moved above the foundation pit, and then the hydraulic rod 2 pushes the U-shaped frame 3 to move downward, and the electric screwdriver rod 8 is moved to a suitable position along the sliding frame 7. The electric screwdriver rod 8 removes the bolts on the protective equipment, and then the staff operates the clamping screw 9 to drive the clamping plate 10 to clamp the protective equipment in the foundation pit, and the hydraulic rod 2 retracts the U-shaped frame 3, and the protective equipment will be taken out of the foundation pit. Then the staff turns the turning handle 55 to drive the adjusting screw 54 to rotate. While the adjusting screw 54 rotates in the fixing column 51, the support frame 1 will rise accordingly, and the support frame 1 is adjusted to a suitable position. The staff pushes the support frame 1 to move and removes the support loaded with the protective equipment. The support frame 1 is moved to the maintenance center, and a damper 58 is fixedly connected to the surface of the first fixed plate 53, and a spring 57 is sleeved on the arc surface of the damper 58. The spring 57 is fixedly connected to the first fixed plate 53, and the other end of the spring 57 is fixedly connected to the second fixed plate 59, and the second fixed plate 59 is fixedly connected to the damper 58, and the second fixed plate 59 is fixedly connected to the universal wheel 4. When passing through a bumpy road, the spring 57 on the second fixed plate 59 will buffer the impact of the bumpy road, and the damper 58 will control the expansion and contraction of the spring 57, so that The support frame 1 is more stable when moving, and a round rod 52 is fixedly connected to the surface of the first fixed plate 53, and the round rod 52 is slidably connected to the support frame 1. The round rod 52 prevents the first fixed plate 53 from rotating with the adjusting screw 54 when the adjusting screw 54 rotates, and also prevents the first fixed plate 53 from being displaced due to the rotation of the universal wheel 4, and a rubber sleeve 56 is fixedly connected to the surface of the turning handle 55, and the rubber sleeve 56 on the turning handle 55 prevents the staff from slipping when turning the turning handle 55.

[0034] like Figure 5As shown, the support device 6 includes a limit block 61, which is fixedly connected to the support frame 1. The inner wall of the limit block 61 is rotatably connected to a support rod 63. When pushing the support frame 1 to move on the slope, the staff rotates the support rod 63 in the limit block 61 to spread the support rod 63 around the support frame 1, so that the support frame 1 moves on the slope. When it tilts, the support rod 63 will support the support frame 1 to prevent the support frame 1 from tipping over. A fixing hole 64 is opened on the surface of the limit block. The surface of 61 is slidably connected with a fixing pin 62, the size of which matches the size of the fixing hole 64, and then the fixing pin 62 is inserted through the limiting block 61 into the fixing hole 64 to limit the support rod 63.

The electric screwdriver rod 8 removes the bolts on the protective equipment, and then the staff manipulates the clamping screw 9 to drive the clamping plate 10 to clamp the protective equipment in the foundation pit. The hydraulic rod 2 retracts the U-shaped frame 3, and the protective equipment is taken out of the foundation pit. Then the staff turns the handle 55. The rubber sleeve 56 on the handle 55 prevents the staff from slipping when turning the handle 55, and drives the adjusting screw 54 to rotate. When the adjusting screw 54 rotates in the fixed column 51, the support frame 1 will rise accordingly, and the round rod 52 prevents the first fixed plate 53 from rotating when the adjusting screw 54 rotates. The adjusting screw 54 rotates, and at the same time, it also prevents the first fixed plate 53 from being displaced as the universal wheel 4 rotates. The support frame 1 is adjusted to a suitable position, and the staff pushes the support frame 1 to move, and moves the support frame 1 loaded with protective equipment to the maintenance center. When passing through a bumpy road, the spring 57 on the second fixed plate 59 will buffer the impact of the bumpy road, and the damper 58 will control the expansion and contraction of the spring 57, so that the support frame 1 is more stable when moving. By setting the adjusting device 5, when the disassembled protective device is sent to the maintenance center, the staff drives the adjusting screw 54 to rotate by turning the handle 55, and adjusts the height of the support frame 1, so that when the support frame 1 is loaded with protective equipment for transportation, the bottom of the protective equipment is not easy to collide with obstacles, which effectively ensures the safety of the protective equipment when being transported to the maintenance center.

[0036] When pushing the support frame 1 to move on the slope, the staff rotates the support rod 63 in the limit block 61 to stretch the support rod 63 around the support frame 1, and then inserts the fixing pin 62 through the limit block 61 and into the fixing hole 64 to limit the support rod 63, so that the support frame 1 moves on the slope. When it tilts, the support rod 63 will support the support frame 1 to prevent the support frame 1 from tipping over. When the support frame 1 is not needed, the support rod 63 is rotated to fold in the direction of the support frame 1, and the magnet 65 on the support frame 1 will be adsorbed on the magnetic sheet 66, which is convenient for collecting the support frame 1. By setting the supporting device 6, when the support frame 1 moves on the slope road surface, the support rod 63 will support the inclined support frame 1 to prevent the support frame 1 from tipping over due to unstable center of gravity, thereby effectively improving the stability of the movement of the support frame 1.
