Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a lining formwork trolley for open-cut rectangular tunnels, which solves the problem that the lining formwork trolleys for open-cut rectangular tunnels used in modern times do not have the function of collecting welding slag and have poor stabilization effects, etc. , so that when we use this device, because it does not have the function of collecting welding slag, when the staff performs welding work on the trolley, it is easy to cause the welding slag to fall to the bottom of the trolley, which has a great safety hazard and is easy to cause The occurrence of fire accidents has seriously affected the personal safety of the staff, and it is also easy to cause burns to the construction personnel under the trolley.

Abstract

The invention belongs to the related technical field of tunnel engineering, and particularly relates to a lining formwork trolley for an open-cut rectangular tunnel. The lining formwork trolley comprises a bottom frame, mounting frames are arranged above the outer side of the bottom frame, the outer side wall of each mounting frame is connected with a supporting frame, a lifting mechanism is arranged above the outer side of each supporting frame, a rotating mechanism is arranged on the outer side of each supporting frame, a reinforcing mechanism is connected to one end of the outer side of the rotating mechanism, a placing frame is arranged at the top end of the outer side of the lifting mechanism, and a workbench is arranged in front of the outer side of the placing frame. By means of the reinforcing mechanism, when the device is moved to a proper position through a guide rail, a second hydraulic cylinder on the outer side of the reinforcing mechanism drives a second hydraulic rod, a fixing frame and a fixing block to reinforce the device, adjacent devices need to be welded and fixed through a common reinforcing mechanism, mounting and dismounting are not easy, the mounting and reinforcing time of the device is shortened, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field related to tunnel engineering, in particular to a lining formwork trolley for open-cut rectangular tunnels. Background technique [0002] Tunnels are buildings built underground or underwater or in mountains, laying railways or building roads for the passage of motor vehicles. According to their location, they can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. A tunnel that passes under a mountain or hill to avoid a large ramp is called a mountain tunnel; a tunnel that passes under a river or under the sea in order to cross a river or strait is called an underwater tunnel; a tunnel that passes underground in a city to meet the needs of a railway passing through a large city is called a tunnel. For urban tunnels, the most built of these three types of tunnels are mountain tunnels. Since Britain began to build the 770-meter-long Taylor Mountain single-track tunnel and...
