Problems solved by technology
[0002] At present, in the tunnel excavation process, in order to prevent the rocks on the upper wall of the tunnel from falling or even collapsing, it is necessary to erect an arc-shaped stand on the tunnel while digging to support the tunnel. Since there are multiple steps in the stand installation process, it usually takes It can only be completed by the cooperation of multiple machines, and the handover of the stand between multiple machines requires precise cooperation between multiple machines. However, due to the complex terrain of the tunnel excavation site, there are certain difficulties in the precise cooperative work between the machines. It is quite troublesome to install the erection, and usually when erecting, multiple manuals are required to assist in the installation, the installation efficiency is low, and too many manual operations also lead to hidden dangers in construction safety

Embodiment Construction
[0026] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0027] refer to Figure 1 to Figure 10 , an excavation stand lifting mechanism of the present invention includes a base frame 1, a guide rail 2, a stand carrying trolley 3, a telescopic platform 4, a jacking mechanism 5 and a lifting device.
[0028] The guide rail 2 is laterally and fixedly installed on the base frame 1 . In this embodiment, two guide rails 2 are provided for more stable carrying and transportation of the stand, and the laying direction of the guide rails 2 is along the direction of tunnel extension and excavation. The base frame 1 is provided with a workbench 11 between two guide rails.
[0029] The stand-carrying trolley 3 is installed on the guide rail 2 and can be transported in translation along the guide rail 2. Each guide rail 2 is provided with a stand-carrying trolley 3, and the stand-carrying trolley 3 is connected with a t...
