[0028] In the preferred embodiment of the present application, as Figure 2 shown, in order to facilitate flexible transfer at the construction site and then improve the efficiency of reinforcing steel hoisting, the walking part 20 includes driven wheels 21 and driving wheels 22 fixed at the bottom end face of the support frame 10 and arranged at intervals, the driving wheel 22 includes a driving mechanism 221 and a driving wheel 222, the driving mechanism 221 is fixed on the support frame 10 and is arranged to drive the driving wheel 222; then the driving of the driving wheel is realized under the action of the driving mechanism, and the position of the entire support frame is changed under the joint action of the driven wheels, so as to adapt to different construction sections and significantly improve the construction efficiency.

[0031] In the preferred embodiment of the present application, as shown in Figure 2 and Figure 3 In order to timely and quickly transport the waste generated in the construction process, the support part 30 fixed on the support frame 10 and extending along the length direction of the support frame 10 is further included. Preferably, the support part 30 is arranged through the support frame 10, thereby improving the space utilization rate of the steel trolley matched with the TBM synchronous lining and realizing the diversification of functions. Specifically, the support part 30 includes a support frame 31 and at least two groups of rolling wheels 32, the rolling wheels 32 are fixed on the support frame 10 and arranged at intervals along the length direction of the support frame 10, and the support frame 31 is movably arranged with the support frame 10 through the rolling wheels 32. Therefore, the support frame can be flexibly changed in position in different processes by movably arranging the support frame with the support frame through the rolling wheels, for example, the belt conveyor arranged in the support frame and the cable arranged through the support frame. The influence of the offset of the conveying device due to the deflection of the excessively long conveying device on the construction can be reduced, the problem that the construction efficiency is not high due to the need to constantly disassemble the support frame fixed on the wall is solved, and therefore the TBM working platform can timely and quickly transport the waste generated in the construction process or the required materials, thereby improving the construction efficiency.

[0032] Specifically, the rolling wheels 32 are arranged between the support frame 31 and the support frame 10, so as to offset the frictional resistance of the support frame in the moving process.

For example, water pipes, air pipes and cables. Thus, the damage to the related cables caused by the TBM construction and the site switching process is reduced. Preferably, in the vertical direction, the first rollers 314 are arranged in a staggered manner below the first supporting rollers 313, and a cavity for accommodating the passage of the wire pipe is formed between the first supporting rollers 313.

The baffle 33 is located above the first rack 31 in the vertical direction. Thus, by arranging the baffle, the damage of the entire support part caused by the falling of waste is effectively reduced, and the safety and stability of the construction equipment are ensured.

[0042] Optionally, the transfer device 63 includes a cantilever mechanism 631 and a tensioning mechanism 632. The cantilever mechanism 631 is rotatably configured with respect to the placement platform 61. One end of the tensioning mechanism 631 is fixed to the placement platform 61, and the other end, which is opposite to it, is retractably driven connected to the distal end of the cantilever mechanism 631 away from the placement platform 61. Thus, through the tensioning mechanism retractably driven connected to the distal end of the cantilever mechanism, the height of the cantilever mechanism can be flexibly adjusted, thereby achieving precise control over the height and position of the reinforcing bars carried by the cantilever mechanism. Combined with the cantilever mechanism rotatably configured with respect to the placement platform, the lifting operation of the reinforcing bars can be realized.

The ventilation section 70 has a gradually decreasing inlet cross-sectional radius and a gradually increasing outlet cross-sectional radius. Thus, by extending the ventilation section along the length of the support frame and by having a gradually decreasing inlet cross-sectional radius and a gradually increasing outlet cross-sectional radius, the flared openings formed at both ends of the ventilation section effectively prevent damage to the duct from sharp ends, ensuring that the flexible duct can smoothly pass through the trolley after detaching from the tunnel ceiling.
