In this way, the embodiment of the utility model installs telescopic platforms 4 on the two side wings of the load-bearing platform 2. The telescopic platforms 4 increase the workable area of ​​the workers, so that the tunnel steel arch frame installation trolley can adapt to the cross-sectional forms of different sizes of tunnels, which can not only improve the operational safety, but also be suitable for the narrow space of the tunnel. In addition, the work efficiency is improved and the manual labor is reduced in the tunnel construction, making the tunnel steel arch frame installation trolley more flexible and practical to use.

Please continue to refer to Figure 4 The side slidable telescopic platform of the embodiment of the utility model includes a platform device 41 and a telescopic device 42. The telescopic device 42 matches the embedded slide rail, and the telescopic device 42 can slide forward and backward along the embedded slide rail. The telescopic device 42 of the embodiment of the utility model has a lateral telescopic function.

The embodiment of the utility model realizes the sliding of the telescopic platform 4 relative to the load-bearing platform 2 through the cooperation of the above-mentioned slide rail 3 and the telescopic platform 4, which solves the defect that the existing tunnel steel arch frame installation trolley is heavy and inconvenient to move and adjust at the construction site.

[0039] Considering that the existing tunnel steel arch installation trolley cannot adapt to all tunnel environments, especially for curved and narrow tunnels, the size and turning radius of the existing tunnel steel arch installation trolley limit its scope of use. Figure 1 , Figure 2 and Figure 3 , Figure 1 Schematic diagram of the structure of the trolley for installing the tunnel steel arch; Figure 2 This is a side view of the trolley for installing the steel arch frame of the tunnel under construction. Figure 3 for Figure 1In the partial enlarged view of part A, the embodiment of the utility model, based on the above-disclosed scheme, further installs multiple hydraulic cylinder lifting devices 8 inside the trolley body 1; the hydraulic cylinder lifting devices 8 are vertically arranged along the height direction of the trolley body 1; the lifting ends of the hydraulic cylinder lifting devices 8 are connected to the load-bearing platform 2.
