Problems solved by technology
[0002] The traditional subway track-laying vehicle is a rail-wheel type, driven by a motor-driven reducer chain, with a transport weight of about 10 tons and a driving speed of 2km / h. Before operation, it is necessary to install and fix temporary auxiliary rails on the circular segment with anchor bolts. Subway track laying The car walks on the track and has no steering function. The laying of temporary auxiliary track not only causes damage to the subway tunnel segment, but also requires a lot of manpower to install and disassemble the auxiliary track, which directly affects the efficiency, safety and cost of subway construction.
[0003] When the wheel-rail subway track-laying car is running, the hoist is driven by electricity. The cylinder of the subway track-laying car's appearance size adjustment (increase in height and width) is powered by a hydraulic station. The whole car has no less than five motors, and the power line There are many cables, the control is more complicated, and there are greater safety hazards

The invention relates to the disadvantages of the subway rail laying vehicle in terms of safety and production efficiency in terms of safety and production efficiency, and relates to the field of subway track laying equipment. The invention adopts hydraulic power, does not need to lay a temporary track in the subway tunnel segment, and has a steering function. The technical scheme of the invention comprises a gantry mechanism, a hoisting mechanism, a driving mechanism assembly and a hydraulic control system. The gantry mechanism comprises four upright columns and a lifting mechanism is arranged on a gantry mechanism. The driving mechanism assembly is arranged at one side of the door frame mechanism, and the walking mechanism has two groups. Each set of walking mechanism comprises a frame, a wheel, an inclined bracket, a walking motor, a rotary support and a steering cylinder.
