[0002] TBM tunnel battery tractors have high requirements on safety when discharging slag or transporting materials. If a rollover accident occurs, it will cause great property losses and even delay the construction period
The treads of the TBM tunnel battery traction wheel pairs in the prior art are mostly conical structures. This structure helps to keep the tractor moving along the centerline of the rails during operation, and reduces the wear of the rails on the wheel rims. Causes of unstable operation of the tractor, or even serpentine movement
[0003] In the prior art, there is a way to make the tractor run smoothly by reducing the taper of the tread, but while running smoothly, it also causes increased wheel rim wear and greatly reduces the service life of the wheel

The invention discloses a TBM tunnel storage battery tractor wheel set which is stable in operation and resistant to abrasion. The invention relates to the technical field of tractor wheel set devices. The TBM tunnel storage battery tractor wheel set comprises a tractor wheel set body, the tractor wheel set body comprises a driving shaft, wheels and bearings. The tractor wheel set body is connected with a tractor suspension through a bearing, each wheel comprises a rim and a tread, a damping rim capable of moving along the axis of the driving shaft is further installed at the end, away from the rim, of the tread, and the tread between the outer end face of the rim and the inner end face of the damping rim on the same side is used in cooperation with a rail. The invention provides a TBM (Tunnel Boring Machine) tunnel tractor wheel set which runs stably and is wear-resistant. By improving the structure of the traction vehicle wheel set, the TBM tunnel traction vehicle can run stably at ahigh speed, rapid abrasion of a rail to a wheel flange can be avoided, so that the safety performance of the TBM tunnel traction vehicle is improved, and the service life of the traction vehicle wheel set is prolonged.
Description
technical field [0001] The invention relates to the technical field of a traction wheel pair device, in particular to a stable and wear-resistant TBM tunnel battery traction wheel pair. Background technique [0002] TBM tunnel battery tractors have high requirements on safety when discharging slag or transporting materials. If a rollover accident occurs, it will cause great property losses and even delay the construction period. The treads of the TBM tunnel battery traction wheel pairs in the prior art are mostly conical structures. This structure helps to keep the tractor moving along the centerline of the rails during operation, and reduces the wear of the rails on the wheel rims. Causes of unstable operation of the tractor or even serpentine movement. [0003] In the prior art, there is a way to make the tractor run stably by reducing the taper of the tread, but while running smoothly, the wear of the wheel rim is aggravated, and the service life of the wheel is greatly ...
