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.

The invention discloses a mobile telescopic platform for tunnel construction and relates to the technical field of tunnel construction equipment. It includes a first mobile platform and a second mobile platform. The first mobile platform is slidably connected to the trolley platform and two second hydraulic cylinders are hinged under the side away from the trolley platform. The first mobile platform is on a side far away from the trolley platform. There are also two third hydraulic cylinders hinged below the side, the second hydraulic cylinder and the third hydraulic cylinder are both hinged with the second mobile platform, and there are two rotating shafts between the first mobile platform and the second mobile platform, one The second hydraulic cylinder, a third hydraulic cylinder, the first mobile platform, and the second mobile platform form a parallelogram, and the rotating shaft is the diagonal line of the parallelogram; one end of the trolley platform is connected with the first hydraulic cylinder, and the first hydraulic cylinder Drive the first mobile platform to move along the track. The invention has the advantages of simple structure and convenient use, improves the safety of personnel passing in the shield tunnel construction in the track area, and reduces the occurrence of safety accidents.
Description
Technical field [0001] The present invention relates to the technical field of tunnel construction equipment, specifically refers to a mobile telescopic platform for tunnel construction. Background [0002] A shield boring machine is a tunnel boring machine that uses the shield method. The tunnel excavation diameter is φ6450mm. The left side of the tunnel is laid with fixed walkway boards, each piece of the walkway board is 500mm wide and 2450mm long, and the bottom support is made of 50mm × 50mm angle steel as a tripod base, fixed to the segment bolt. During the construction and excavation process, the shield machine is gradually installed with a fixed walkway board to meet the passage of tunnel construction workers. Because the average distance of each ring excavation of the shield machine is 1200mm, and the fixed length of the walkway plate is 2450mm, as the shield machine pushes forward, a spacing of 0-2000mm will be formed between the 6# trolley of the shield machine and the...
