Problems solved by technology
[0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arch frames are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch frames cannot match the mechanized on-site construction of arch frames
[0004] In order to solve the problems existing in the steel arches in the prior art, manipulators have gradually appeared in the arching operation. However, the current manipulators use the steel arch clamping equipment to hold several sections of the steel arch at the same time, and then Fixed connections such as welding are performed on the joints. Such operations also require more labor, and the safety cannot be guaranteed.
Therefore, with the development and progress of technology, foldable steel arches have gradually appeared. After the steel arches are installed and folded, they are transported to the tunnel for unfolding and erection operations, leaving a lot of operations on the steel arches. Outside the tunnel, it solves the time-consuming and labor-consuming problems of erecting steel arches in the existing tunnel construction
[0005] However, there is no good steel arch clamping device in the prior art to solve the problem of stable transportation and clamping of the folded steel arch in the tunnel.

The invention discloses an arch bracket clamping device which comprises a main beam. Arch bracket clamping mechanisms are arranged at the two ends of the main beam, and the two sides of the main beamare provided with arch bracket supporting frames. By means of the clamping device, a folded steel arch bracket can be stably and reliably clamped, and safety of transportation and erection of the folded steel arch bracket in a tunnel is ensured.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel steel arch construction technology. Background technique [0002] In recent years, my country's underground engineering has developed rapidly, and mechanized operations have gradually been widely used in engineering technology, especially in the field of underground tunnel construction. [0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arches are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch constructions cannot cooperate with mechanized on-site construction of arch...
