At present, there are some mobile working platforms on the market, but when they are used for construction in tunnels, they are often difficult to move flexibly due to space limitations, and lack effective stable support mechanisms.

[0003] Specifically, when the working platform is raised to a relatively high position, it will affect the stability of the working platform and is prone to tipping. Utility Model Content

[0013] A servo motor is fixedly connected to the outer wall of the top of the auxiliary seat, and the output shaft of the servo motor is fixedly connected to the screw rod.

[0014] With the above structure, the setting of the servo motor facilitates directly driving the rotation of the screw rod, and when the screw rod rotates, it facilitates directly driving the movement of the sliding column.

[0015] The lifting assembly includes a mounting frame fixedly connected to the outer wall of the top of the base, and two symmetrically arranged mounting ears are fixedly connected to the outer wall of the top of the mounting frame. A first mounting rod is slidably connected to the outer wall of the top of the mounting frame.

A first hydraulic cylinder is rotatably connected to the inner wall of the mounting frame, and one end of the piston rod of the first hydraulic cylinder is rotatably connected to the scissor lift.

[0016] With the above structure, the mounting ears on the mounting frame facilitate the installation of the scissor lift, and the setting of the first hydraulic cylinder facilitates directly adjusting the expansion and folding of the scissor lift.

[0017] The platform assembly includes an operation platform, and a guardrail is fixedly connected to the outer wall of the top of the operation platform.

[0018] With the above structure, the setting of the guardrail facilitates protecting the staff on the operation platform.

[0019] A second mounting rod is fixedly connected to the outer wall of the bottom of the operation platform, and two symmetrically arranged fixing frames are fixedly connected to the outer wall of the bottom of the operation platform. A third mounting rod is slidably connected to the inner walls of the two fixing frames.
