Tunnel construction trolley

Abstract

The invention discloses a tunnel construction trolley, which structurally comprises a sleeper, rails, walking machine wheels, portals, linkage mechanisms, jacks and an outer film plate. One pair of rails is installed; each rail is of an I-shaped structure; the rails are respectively welded onto the upper surface of the two ends of the sleeper; one pair of walking machine wheels is installed; eachwalking wheel is positioned between the corresponding rail and the corresponding portal; the corresponding walking wheel, rail and portal are engaged; each rail and the corresponding portal are in ascending and descending connection through the walking machine wheel; the portals are at least three and are of arc-shaped structures; and the two side surfaces of the portals are fixedly connected withthe inner side surface of the outer film plate through connecting welding strips. The tunnel construction trolley has the advantages that the manual injection is not needed during the grouting; afterthe grouting is completed, the manual locking on a lock bolt is not needed; the time and the labor are saved; the labor cost is low; and the safety guarantee is improved.

Description

technical field [0001] The invention relates to a tunnel construction trolley, which belongs to the field of construction trolleys. Background technique [0002] With the development of society and the advancement of science and technology, large-scale and efficient construction machinery should be put into use, but for underground tunnels, due to the limitations of economic conditions and technical levels, it is difficult for large-scale machinery to perfectly complete the tunnel. For construction and protection, a large number of tunnels are still constructed manually, but manual construction poses a safety threat. [0003] In the prior art, the tunnel requires 2-3 times of grouting during construction, and each grouting needs to be injected manually. After each grouting is completed, the locking bolts need to be manually locked to strengthen the fastening, which is time-consuming. It is laborious, the labor cost is high, and safety cannot be guaranteed. Contents of the...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a tunnel construction trolley to solve the need for 2-3 times of grouting when the tunnel is being constructed. Each grouting requires manual injection, and each grouting After the completion, it is necessary to manually lock the lock bolt and strengthen the fastening, which is time-consuming, labor-intensive, high labor cost, and cannot guarantee safety.
