Problems solved by technology

[0004] In the above scheme, workers can use the working platform to carry out construction inside the tunnel, but the position of the working platform on the frame is fixed and the inner wall of the tunnel is arc-shaped. When constructing in different positions, it is necessary to constantly change postures, and long-term work will increase fatigue, so it will be inconvenient to construct on the top of the tunnel

Abstract

The invention relates to a working platform for construction in a tunnel. The working platform comprises a frame body and a walking assembly arranged at the bottom of the frame body, wherein a fixingplate is horizontally arranged at the top of the frame body, the working platform is horizontally arranged above the fixing plate, and a lifting mechanism is arranged between the working platform andthe fixing plate and used for conducting lifting and falling on the working platform. The working platform has the advantage that since the working platform can lift and fall, convenience is brought for constructors to conduct construction on the top of the tunnel.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a construction work platform in a tunnel. Background technique [0002] Tunnel construction has the characteristics of narrow working face, poor working conditions, many processes, and large interference. When grouting or repairing the expansion joints of the tunnel, due to the large diameter of the tunnel, the construction is often carried out with the help of a working platform. [0003] The invention patent with authorized notification number CN102704952B discloses a self-propelled tunnel grouting trolley, which includes a frame, a working platform and a walking assembly. The working platform is horizontally arranged on the top of the frame and the walking assembly is arranged on the bottom of the frame. [0004] In the above scheme, workers can use the working platform to carry out construction inside the tunnel, but the position of the working platform on the fr...
