Problems solved by technology

Because the excavation process of each ring of the shield machine is 1200mm on average, and the fixed length of the walkway is 2450mm, as the shield machine advances, there will be a gap of 0-2000mm between the 6# trolley of the shield machine and the fixed walkway of the tunnel. Equal spacing, this spacing is inconvenient to install and fix the aisle slab, resulting in the failure of normal connection between the 6# trolley and the aisle slab
In this case, the construction workers in the tunnel need to go down to the track work area, and then walk to the 6# trolley through the ladder.

Abstract

The invention discloses a movable telescopic platform for tunnel construction, and relates to the technical field of tunnel construction equipment. The movable telescopic platform comprises a first moving platform and a second moving platform, wherein the first moving platform is slidably connected with a trolley platform, two second hydraulic cylinders are hinged to the lower face of the side, away from the trolley platform, of the first moving platform, two third hydraulic cylinders are further hinged to the lower face of the side, away from the trolley platform, of the first moving platform, the second hydraulic cylinders and the third hydraulic cylinders are both hinged to the second moving platform, two rotating shafts are further arranged between the first moving platform and the second moving platform, one second hydraulic cylinder, one third hydraulic cylinder, the first moving platform and the second moving platform form a parallelogram, the rotating shafts are diagonal lines of the parallelograms, one end of the trolley platform is connected with a first hydraulic cylinder, and the first hydraulic cylinder drives the first moving platform to move along rails. The movable telescopic platform is simple in structure and convenient to use, the personnel passing safety of the shield tunnel construction rail-mounted area is improved, and safety accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a mobile telescopic platform for tunnel construction. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The shield method is used for construction, and the tunnel excavation diameter is φ6450mm. Fixed walkway slabs are arranged on the left side of the tunnel. Each walkway slab has a width of 500mm and a length of 2450mm. The bottom support uses 50mm×50mm angle steel as the tripod base and is fixed on the segment bolts. During the construction and excavation process of the shield machine, the supporting fixed walkway slabs are gradually installed to meet the passage of tunnel construction workers. Because the excavation process of each ring of the shield machine is 1200mm on average, and the fixed length of the walkway is 2450mm, as the shield machine advances, there will be a gap of 0-2000mm between the ...
