[0008] A workbench is rotatably connected with the telescopic arm, a fourth hydraulic cylinder is rotatably connected between the workbench and the telescopic arm, the fourth hydraulic cylinder adjusts the workbench to be in a horizontal state, the electric rotary table and the telescopic arm change the position of the workbench, the staff can move in the air in a larger range, and the steel structure building is constructed conveniently.

[0009] Furthermore, an anti-tilt arm is rotatably connected to the side of the base via a U-shaped seat. A support foot is screwed onto the anti-tilt arm, and a handle is inserted into the upper end of the support foot. Rotating the support foot to contact the ground ensures that the base will not tilt and is safe to use. A limit frame is installed on the side of the base, and the size of the limit frame matches the anti-tilt arm. A stop post is inserted into the limit frame to prevent the anti-tilt arm from automatically unfolding after it is retracted.

[0010] Furthermore, a lifting ring is fixedly connected to the right end of the support arm, which can lift some items, thus enriching the functions of the lifting platform.

[0011] Furthermore, the electric turntable includes a worm gear reducer and a disc connected to the worm gear reducer. The support is connected to the disc, and the base is equipped with several universal balls that contact the disc, thereby improving the stability of the disc's rotation and reducing the load on the worm gear reducer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The support arm and telescopic arm can be extended to lift the workbench to a high position. The fourth hydraulic cylinder controls the workbench to rotate to a horizontal position to ensure that the staff can stand on the workbench smoothly. The third hydraulic cylinder controls the translation of the workbench, and the universal ball controls the turning of the workbench, so that the workbench can be flexibly adjusted in the air and its position can be changed in time according to the needs of the staff, making it more convenient to use.

[0014] (2) Rotate the anti-tilt arm vertical base, and then twist the support foot to contact the ground. This can improve the anti-tilt ability of the base. Retract the anti-tilt arm into the limit frame. The stop post blocks the anti-tilt arm from rotating, preventing the anti-tilt arm from automatically unfolding. This ensures strong stability.

[0015] (3) The first placement seat supports the support arm, and the second placement seat supports the telescopic arm. When the lifting platform is not in use, the pressure of the hydraulic cylinder is reduced, and the lifting ring can lift the heavy object and smoothly lift the heavy object into the air.
