Problems solved by technology
The tunnel construction environment is complex, requiring a variety of mechanical vehicles to pass through the interior, while ensuring that the upper working platform compresses the lower space, causing great safety hazards
The narrow internal space also makes ventilation difficult, and the air quality in the tunnel is poor, which affects human health; the large size of various components also increases the difficulty of assembly and welding, and inconvenient movement

The invention discloses a gantry supporting structure for a tunnel lining trolley. The gantry supporting structure is characterized in that an arched gantry is arranged, a left vertical pillar and a right vertical pillar are connected through top cross beams, and the backs, facing the tunnel side wall of one side where the vertical pillars are arranged, of C-shaped parts of the left and right vertical pillars are arch-shaped; top longitudinal beams are fixedly connected between the top cross beams of a front gantry and a rear gantry; trusses are arranged between the top longitudinal beams at intervals in the longitudinal direction, wing poles extending out of two ends of each truss are supported on the top longitudinal beams, adjustable connecting rods are arranged at the end parts of the wing poles, and lining formwork back ribs are connected through the adjustable connecting rods. The whole structure can advance along horizontal tracks in a tunnel by means of walking wheels. Dead weight of the trusses and support force of the truss support formworks are transmitted to the arched gantries to form large headroom, accordingly, tunnel ventilation is facilitated, and bottom work of the lining trolley is facilitated.
Description
technical field [0001] The invention belongs to the field of lining trolleys, and more specifically relates to a gantry support structure of a lining trolley used in the secondary lining construction of a tunnel, in order to ensure good ventilation of the tunnel and provide a large clearance section and a large clearance for the lining trolley. Upper working platform. Background technique [0002] The lining trolley is an important equipment in the secondary lining construction process of the tunnel, and it is used for the secondary lining concrete construction of the inner wall of the tunnel. At present, the commonly used lining trolley is a portal trolley, and the portal frame is located in the lining formwork, occupying a large amount of internal space. The tunnel construction environment is complex, and various mechanical vehicles are required to pass through the interior. In order to ensure that the upper working platform compresses the lower space, there are great saf...
