Hydraulic tunnel pipeline installation trolley, installation system and installation method

Abstract

The invention relates to a hydraulic tunnel pipeline installation trolley, installation system and installation method, comprising a main girder, a traveling mechanism and a trolley carrying pipes, and a track is arranged above the main beam; The first walking support, the first supporting, the second walking supporting, the second supporting, the third walking supporting, the third supporting, the fourth walking supporting and the fourth supporting under the main girder, the first walking supporting, the first supporting, The second walking support, the second supporting, the third walking supporting, the third supporting, the fourth walking supporting and the fourth supporting are all equipped with jacking mechanism; the said carrying pipe trolley is installed on the track for supporting and translating the pipeline , The top of the piggyback trolley is equipped with a rotating unit for adjusting the angle of the pipeline. When using the equipment involved in the present invention to install pipelines in the tunnel, after the pipeline joints are transported into the tunnel, the position and angle of the pipe joints can be adjusted conveniently, which is beneficial to the butt joint of adjacent pipeline joints and improves the quality of welding between pipe joints .

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a hydraulic tunnel pipeline installation trolley, an installation system and an installation method. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels and mine tunnels; the structure of the tunnel includes two parts, the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door. The auxiliary equipment includes car avoidance tunnels, fire protection facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. Among them, in the processing and application of hydraulic tunnels, it is usually necessary to place large-scale steel pipes to realize water pa...

Problems solved by technology

[0004] However, the space in the tunnel body is limited. When the above-mentioned device is used for butt welding of large-scale penstock steel pipes, once the steel pipes are transported into the tunnel, it is difficult to adjust the height, angle and position of the steel pipes. The accuracy of transporting steel pipes is very high, and construction is easy. The problem of docking failure between pipe joints occurs

In addition, because the pipe is formed by curling steel plates, for large pipes such as tunnel water pipes, the front and rear ends cannot be completely aligned during the steel plate curling process, and the parts that cannot be aligned need to be cut later, so the front and rear ends of the pipe A slope will be formed. In order to make the adjacent pipes fully docked, it is necessary to mark the marking points at the nozzles on both sides of the pipes or set corresponding interface grooves at the interface. When connecting adjacent pipes, it is necessary to rotate the pipes axially to make the adjacent pipes Align the marking points or interface grooves, and then complete the welding, so that the pipes at both ends can be completely aligned. However, when the traditional large-scale pressure steel pipes are butt welded, the pipes are large in size and the operating space in the tunnel is limited, so the rotation is difficult.
