Description

Technical Field

[0001] The invention relates to the technical field of tunnel engineering, in particular to a translation track changing system for large-volume heavy-duty equipment in a narrow space. Background Art

[0002] As we all know, in engineering practice, equipment needs to be installed in the tunnel equipment room. However, in some tunnel projects, large-volume and heavy-duty equipment is large in size and tonnage and does not have the ability to move itself. It is often necessary to place the equipment on a rail flatbed car and transport the equipment to the vicinity of the predetermined point in the tunnel equipment room through the use of common turnouts, hoisting and other technologies.

[0003] However, in tunnel engineering, due to geological conditions, excavation and backfilling costs and other factors, the space between tunnel equipment is often small. 1) The use of turnout mobile track change technology is limited by the width and length of the tunnel equipment, and the turning radius of laying curved tracks is small, while the turning radius required for large-volume equipment to turn is large. Therefore, large-volume equipment cannot change tracks through turns in a narrow cave chamber. 2) When using lifting technologies such as overhead cranes or vehicle-mounted cranes, heavy lifting equipment has a large structure and a large operating space, which is not suitable for the mobile track change of heavy equipment in a small space. Customized overhead cranes are expensive, have a low frequency of use, and are not economical. Summary of the invention

[0004] The purpose of the present invention is to provide a translational track change system for large-volume heavy-duty equipment in a narrow space, so as to solve the problem of movement and track change of large-volume heavy-duty equipment in a narrow space proposed in the above background technology.

[0006] As a further solution of the present invention: the main body of the bottom plate is a thick steel plate, and reinforcement angle steels in both vertical and horizontal directions are welded on the bottom plate.

[0007] As a further solution of the present invention: the laser rangefinder and the walking track are perpendicular to each other in space.

[0008] As a further solution of the present invention: the travel track is a set of parallel steel rails, a supporting connecting rod is arranged between two steel rails, and the two steel rails are connected by the supporting connecting rod.

[0009] As a further solution of the present invention: the hoist is fixedly connected to the side wall anchor rod installed in the tunnel equipment room.

[0010] As a further solution of the present invention: rail clamps are arranged at equal distances on both sides of the running track, and the running track is fixed to the bottom plate through the rail clamps.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1.
