[0024] Push the mobile base 1 to drive the operating platform 3 and the support frame 6 to move. Then, drive the support block 17 through the motor 16 to drive the cylinder 18 to rotate perpendicular to the ground. Then, drive the fixing plate 19 downward through the cylinder 18 to be close to the ground, and penetrate the fixing piles 20 through both sides of the fixing plate 19 into the ground to achieve the effect of fixing the mobile base 1, the operating platform 3 and the support frame 6 to prevent sliding;
[0025] The scissor lift 2 drives the operating platform 3 and the maintenance personnel to move upward to the position to be repaired for easy maintenance;
[0026] Since maintenance personnel cannot carry too many maintenance tools themselves, the industrial motor 9 drives the reciprocating lead screw 7 to rotate, causing the sliding sleeve 10 to drive the support plate 11 and the fixture 14 to reciprocate along the slide rail 8. Then, the industrial hydraulic cylinder 13 drives the fixture 14 to move up and down, clamp the maintenance tools on the top of the moving base 1, and deliver them to the maintenance personnel for use. This reduces the weight that the maintenance personnel need to carry, and the tools will not fall and hurt people.
[0027] To improve the safety of maintenance, for example, as Figure 1 shown, the present invention further includes that one side of the operation table 3 is connected to a safety door 4 through a rotating shaft, and a lock catch 5 is provided on one side surface of the safety door 4.
[0028] During use, after the maintenance personnel enter the operation table 3, they rotate the safety door 4 and use the lock catch 5 to lock the operation table 3 and the safety door 4 to each other, so as to achieve a certain effect of protecting the maintenance personnel from falling.
[0029] For example, as Figure 1 shown, the present invention further includes that the operation table 3 is located on the top of the moving base 1 and on the bottom side of the support frame 6.
[0030] For example, as Figure 1 shown, the present invention further includes that an industrial motor 9 is provided on one side of the support frame 6 corresponding to the position of the reciprocating lead screw 7, and the driving end of the industrial motor 9 is connected to the reciprocating lead screw 7 through a rotating shaft. A sliding sleeve 10 is sleeved on the periphery of the reciprocating lead screw 7. One side of the sliding sleeve 10 is fixed to the support plate 11 by bolts, and the other end of the support plate 11 is slidably connected to the slide rail 8 through a slider.
[0031] During use, the industrial motor 9 drives the reciprocating lead screw 7 to rotate, causing the sliding sleeve 10 to drive the support plate 11 and the fixture 14 to reciprocate along the slide rail 8, so as to facilitate transporting the maintenance tools to the operation table 3 for the maintenance personnel to pick up.
[0032] For example, as Figure 1 、 Figure 2 shown, the present invention further includes that a connecting block 12 is provided at the center position of the bottom of the support plate 11, an industrial hydraulic cylinder 13 is provided at the bottom of the connecting block 12, and the bottom driving end of the industrial hydraulic cylinder 13 is connected to the fixture 14 through screws.
[0033] During use, the industrial hydraulic cylinder 13 drives the fixture 14 to move up and down, clamp the maintenance tools on the top of the moving base 1, and deliver them to the maintenance personnel for use. This reduces the weight that the maintenance personnel need to carry, and the tools will not fall and hurt people.
[0034] For example, as Figure 1As shown in the figure, the utility model further includes that a motor 16 is provided on one side of the concave bracket 15. The concave brackets 15 are connected to the support block 17 through a rotating shaft, and the driving end of the motor 16 is connected to one side of the support block 17 through a rotating shaft. A cylinder 18 is provided at the bottom of the support block 17, and the bottom driving end of the cylinder 18 is connected to the fixed plate 19 through a screw.
[0035] During use, the motor 16 drives the support block 17 to drive the cylinder 18 to rotate perpendicular to the ground, and then the cylinder 18 drives the fixed plate 19 to move downward close to the ground, and the fixing pile 20 penetrates through both sides of the fixed plate 19 and is driven into the ground to achieve the effect of fixing the moving base 1, the operating platform 3 and the support frame 6, and prevent sliding.
[0036] When the utility model is in use, after the maintenance personnel enter the operating platform 3, rotate the safety door 4 and use the lock catch 5 to lock the operating platform 3 and the safety door 4 to each other to prevent the maintenance personnel from falling.
[0037] Push the moving base 1 to drive the operating platform 3 and the support frame 6 to move, then the motor 16 drives the support block 17 to drive the cylinder 18 to rotate perpendicular to the ground, and then the cylinder 18 drives the fixed plate 19 to move downward close to the ground, and the fixing pile 20 penetrates through both sides of the fixed plate 19 and is driven into the ground to achieve the effect of fixing the moving base 1, the operating platform 3 and the support frame 6, and prevent sliding.
[0038] The scissor lift 2 drives the operating platform 3 and the maintenance personnel to be lifted upward to the position that needs to be repaired for easy maintenance.
[0039] However, the maintenance personnel themselves cannot carry too many maintenance tools. Then, the industrial motor 9 drives the reciprocating lead screw 7 to rotate, so that the sliding sleeve 10 drives the support plate 11 and the fixture 14 to move reciprocally along the slide rail 8, and then the industrial hydraulic cylinder 13 drives the fixture 14 to move up and down to clamp the maintenance tools on the top of the moving base 1 and transport them to the maintenance personnel for use, which reduces the weight of the tools carried by the maintenance personnel and also prevents the tools from slipping and hurting people.
