Background

The tunneling machine tunnel construction technology is a construction method for underground tunneling under the ground, and is commonly used for excavating tunnels such as urban subway tunnels, hydraulic tunnels, river crossing tunnels, railway tunnels, highway tunnels, municipal pipelines and the like.

At present, two sets of tracks are required to be paved in the construction of a heading machine: the temporary paved track is used for walking of the heading machine, is disassembled along with walking, and is continuously paved before the disassembled steel rail is transferred to the rollers of the heading machine. The other set of long-term paved track is used for locomotive running, and the material supply required by tunnel construction is ensured. The track of the heading machine in the heading machine driving-out area is removed in time and is conveyed to the front part of the heading machine to be continuously used for paving the track of the heading machine. The smooth circulation of the process is an important guarantee for the stable running of the heading machine. The weight of each steel rail for paving the track of the development machine is about 560kg, and 4-8 steel rails are required to be dismantled, dumped and paved in each shift, so that the workload is huge. At present, the disassembly, the transportation and the laying of the rails in the above procedures are realized by a great deal of manpower. Because the track is heavy in weight, small in operation space, and completely depends on manual operation, the labor intensity is high, the operation efficiency is low, and the construction cost is high.

The construction of the existing track transferring and paving device has the following defects:

1. The traditional construction adopts manual disassembly, transportation and laying of the steel rail of the heading machine, and has the advantages of high labor intensity, low operation efficiency and high construction cost. Meanwhile, because the steel rail has large self weight and small operation space, operators have certain safety risks;

2. The existing patent is concentrated in the field of track dismantling after track transportation or development machine construction is finished, and no automatic equipment for track dismantling, transporting and paving during development machine construction exists;

3. The heavy objects (cutters, grease barrels and the like) are transferred to the trolley of the heading machine, and are mainly realized by means of a chain block or manpower fixed on the trolley. Because the installation position of the chain block is fixed, and the labor is limited, the labor intensity for moving the heavy objects on the heading machine trolley is high, the efficiency is low, and the supply of materials is not facilitated.
