However, the purchase cost of the arch frame installation vehicle is extremely high, and the arch frame installation vehicle generally adopts a three-arm design, and the working platform is narrow, making it difficult to synchronously deploy the construction of other processes when performing the arch frame installation work, which is unfavorable to the rapid construction organization of the initial support work of the tunnel. In light of the above situation, it is urgent to develop a tunnel support structure installation device to overcome the current practical application deficiencies.

The object of this invention is to provide a tunnel support structure mounting device that solves the problems proposed in the background art above.

and an adjustment assembly provided between the lift frame and the moving assembly for driving the lift frame to lift and lower the operation platform. In this case, the fixing mechanism includes:
a mounting assembly connected to the operation platform for providing support and fastening to the arch frame;
and a rotating assembly disposed between the mounting assembly and the lifting frame for driving the mounting assembly to realize angle adjustment of the arch frame.

Compared with the prior art, the beneficial effect of the present invention is that during the operation of the device, the arch frame is placed on the mounting assembly, the mounting assembly supports and fixes the arch frame, the rotating assembly drives the mounting assembly to adjust the mounting angle of the arch frame, the moving assembly moves the fixed platform, the adjusting assembly drives the lifting frame to raise and lower the operation platform, and further adjusts the height of the arch frame to ensure the accuracy of the mounting position. This application addresses the problems that the purchase cost of the arch frame mounting vehicle in the prior art is very high, the arch frame mounting vehicle generally adopts a three-arm design, the working platform is narrow, and it is difficult to synchronously deploy the construction of other processes when performing the arch frame mounting work, which is disadvantageous to the rapid construction organization of the initial support work of the tunnel. By installing a fixing mechanism, the stability of the installation of the arch frame can be guaranteed in accordance with the adjusting assembly and the moving assembly, and the position of the arch frame can be flexibly adjusted, ensuring the installation accuracy of the steel arch frame.
