Abstract

The invention discloses a double-arch-bridge type installation machine for a railway tunnel formwork trolley. A first track support and a second track support are arranged on the two sides of the interior of a tunnel primary support section. A first travelling beam is arranged on the first track support in a sliding mode, and a second travelling beam is arranged on the second track support in a sliding mode. A pair of arched beams are arranged between the first travelling beam and the second travelling beam, and a plurality of guide pulleys are arranged on the arched beams. Sliding trolleys are arranged on the arched beams, and pulling ropes are arranged at the two ends of each sliding trolley. After the ends of the two pulling ropes of each sliding trolley move in the opposite directions,the pulling ropes are connected with one driving end of a pulling mechanism. The two sliding trolleys are connected through a transverse beam, and a lifting crane is arranged on the side of the transverse beam. The double-arch-bridge type installation machine for the railway tunnel formwork trolley is simple and exquisite in integral structure and small in occupied space, installation of the double-arch-bridge type installation machine can be achieved under the condition that over-excavation of a tunnel is not required, the manpower labor is greatly relieved, and the efficiency of tunnel operation is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, in particular to a double-arch bridge installation machine for a railway tunnel formwork trolley. Background technique [0002] With the rapid development of our economy, the total length of railway tunnels under construction in my country has far exceeded 7000km, and the completed length of railway tunnels is basically maintained at about 500km each year. As we all know, in the construction process of the tunnel, the formwork trolley is an indispensable equipment for the secondary lining, and the assembly of the formwork trolley is usually carried out in the tunnel according to the centerline of the tunnel. It can only be carried out when an inclined shaft is set up in the middle of the tunnel or a trolley needs to be installed. However, the assembly of the tunnel in the tunnel is limited by the space. Generally, it is carried out in a limited assembly section in the tunnel...
