[0009] Furthermore, a second guardrail is provided around the upper platform, a climbing opening is provided on the upper platform, and a staircase extending to the lower platform is provided on the climbing opening.

[0010] A winch is also installed at the bottom of the upper platform, directly opposite the feeding port.

[0011] Further, a driving motor is arranged on the frame to drive the traveling wheels.

[0012] Further, the width of the upper platform is less than the width of the lower platform.

[0013] Compared with the prior art, the tunnel operation platform has the beneficial technical effects that:

DETAILED DESCRIPTION

[0020] Disclosed in the embodiment is a tunnel operation platform, which comprises a frame 200, a plurality of traveling wheels 201 arranged at the lower end of the frame 200, a lower platform 300 and an upper platform 400 arranged on the frame 200, a rotary adjusting mechanism 500 arranged at the top of the upper platform 400, a scissor lifting mechanism 600 arranged on the rotary adjusting mechanism 500, and a working guardrail 700 arranged at the telescopic upper end of the scissor lifting mechanism 600.

[0021] When in use, because the top of the tunnel is an arch structure, the conventional tunnel operation platform is inconvenient to be directly designed as an arch shape because the space for the operator to operate needs to be reserved.

[0022] Therefore, in the embodiment, the shearing lifting mechanism 600 is installed on the upper platform 400 through the rotary adjusting mechanism 500; on one hand, the shearing lifting mechanism 600 is adjusted by the rotary adjusting mechanism 500 to correspond to each position of the top of the tunnel 100, and on the other hand, personnel or materials can be lifted to the top of the tunnel 100 according to the requirement, so as to facilitate the operator to operate.

[0023] In the embodiment, as shown in the figure, Figure 3 The rotary adjusting mechanism 500 includes a rotary supporting outer shell 502 installed at the center of the upper platform 400, a rotary supporting inner shell 501 fitted and installed in the rotary supporting outer shell 502, and a rotary driving motor 503 driving the rotary supporting inner shell 501 to rotate relative to the rotary supporting outer shell 502; a supporting table is installed at the top of the rotary supporting inner shell 501; the shearing lifting mechanism 600 includes a lifting articulated arm 601 fixed on the supporting table through a mounting table 603, and a lifting adjusting cylinder 602 adjusting the lifting of the lifting articulated arm 601; the shearing lifting mechanism 600 is specifically a scissor lifting machine.

[0024] In use, the rotary supporting inner shell 501 is driven by the rotary driving motor 503 to rotate relative to the rotary supporting outer shell 502, so that the working guardrail 700 at the upper end of the shearing lifting mechanism 600 is located at the position required to be used. Then, the lifting articulated arm 601 is lifted by the lifting adjusting cylinder 602 to lift the working guardrail 700 to the required height.

[0025] In the embodiment, the stairway for personnel to climb to the lower platform 300 is installed on the frame 200, the first guardrail 301 is installed on the periphery of the lower platform 300 to prevent personnel from falling, and the upper loading port 302 is opened at the center of the lower platform 300, and the hoist is used for lifting according to the requirement.

[0026] The second guardrail 401 is installed on the periphery of the upper platform 400, the climbing port 402 is opened on the upper platform 400, and the stairway extending to the lower platform 300 is installed on the climbing port 402; the hoist opposite to the upper loading port 302 is also installed at the bottom of the upper platform 400, which is used for loading or downward transferring tools.

[0027] In the embodiment, the driving motor 202 is installed on the frame 200 to drive the traveling wheels 201, and a traction mechanism can also be used to transfer the position.

[0028] As shown in Figure 1 The width of the upper platform 400 is less than that of the lower platform 300, and the extension of the lower platform 300 and the upper platform 400 facilitates manual operation.
