In this embodiment, the adjustment mechanism 200 includes a first hydraulic cylinder 210, a second hydraulic cylinder 220 and a guide assembly 230. Among them, the first hydraulic cylinder 210 and the second hydraulic cylinder 220 have the same structure and are hydraulic cylinders of the same model. The first hydraulic cylinder 210 and the second hydraulic cylinder 220 are respectively arranged on both sides of the gantry unit 110, and the hydraulic cylinders and the guide assembly 230 on the same side are alternately arranged between the two adjacent gantry units 110 along the vertical direction. Specifically, in the present embodiment, three first hydraulic cylinders 210 and three second hydraulic cylinders 220 are arranged between two adjacent gantry units 110, and two guide assemblies 230 are arranged on one side of the gantry unit 110. When assembling the frame mechanism 100, the guide assemblies 230 are first fixed, and then the first hydraulic cylinders 210 and the second hydraulic cylinders 220 are installed. Through the design of this structure, the guide assemblies 230 serve as the main bearing mechanism, which can reduce the load of the first hydraulic cylinders 210 and the second hydraulic cylinders 220 and increase the service life of the first hydraulic cylinders 210 and the second hydraulic cylinders 220.

[0039] In some embodiments of the present invention, referring to Figure 1 and Figure 4 As shown, the invention also includes a traveling mechanism 300, which is provided with a track wheel 310 and a lifting base 320, and the lifting base 320 is adjustably arranged at the lower end of the gantry unit 110 in the vertical direction; the track wheel 310 and the lifting base 320 are rotatably connected. In this embodiment, the lifting base 320 is adjustably arranged at the lower end of the gantry unit 110 in the vertical direction. Through the design of this structure, the height of the frame mechanism 100 can be adjusted, which is convenient for use in tunnel construction of various heights, and avoids the collision between the upper end of the frame mechanism 100 and the arch of the tunnel when the frame mechanism 100 is walking on the track, thereby improving the safety performance of the device.

[0040] In some embodiments of the present invention, referring to Figure 4 As shown, the track wheel 310 is a T-shaped wheel. In this embodiment, since the tunnel lining trolley based on BIM technology in this embodiment needs to run on the straight section and the turning section of the track, the track wheel 310 with a T-shaped wheel design can avoid the track wheel 310 from getting stuck in the turning section compared to the V-shaped and U-shaped track wheels 310.

[0041] In some embodiments of the present invention, referring to Figure 4 and Figure 5 As shown, the support mechanism 400 is also included, and the support mechanism 400 includes an adjusting screw 410, an adjusting sleeve 420, a supporting rod 430 and a horizontal plate 440.

Specifically, in this embodiment, when the frame mechanism 100 is in a walking state, the vertical height of the horizontal plate 440 is higher than the track wheel 310, and at this time, the support mechanism 400 does not contact the ground of the tunnel. When the frame mechanism 100 moves to the specified position, the adjusting screw 410 is controlled to rotate, so that the support rod 430 is lowered, and the horizontal plate 440 is in contact with the ground, and the frame mechanism 100 is lifted upward. When erecting the formwork arch, the support mechanism 400 serves as the main support. By setting up the horizontal plate 440, the contact area between the lower end of the frame mechanism 100 and the ground is increased, thereby improving the stability of the frame mechanism 100.

In this embodiment, by providing the guide groove 421, the rotation of the supporting rod 430 can be avoided. Furthermore, by providing the fiber sleeve, the moving height of the supporting rod 430 in the vertical direction can be limited, thereby improving the stability of the supporting mechanism 400.
