Problems solved by technology

[0002] TBM (Tunnel Boring Machine) needs support equipment to provide support and reaction force for the propulsion system of the roadheader in the soft rock geological construction process, but the roadheader in the prior art has the following problems: 1. The support force provided by the support equipment is insufficient, resulting in 2. The external auxiliary equipment (such as supporting facilities) connected to the roadheader is too heavy, and the roadheader cannot effectively drag the external auxiliary equipment forward, so that it is impossible to change steps;

Abstract

The invention discloses a support system for a roadheader. The support system includes a mounting part, a stretcher shoe assembly, a power part, a first telescopic part and a second telescopic part; , to provide support and reaction force for the roadheader, and the first telescopic part can push the roadheader forward to change steps, and the second telescopic part drags the external auxiliary equipment forward to realize step change. The invention also discloses a roadheader, which includes a roadheader body, a tension shield and a support system for the roadheader; the invention provides an effective supporting reaction force for the roadheader body by setting the tensioner shield and the support system. Next, the support system can provide the support reaction force and can also push the support shield forward to complete the step change. The invention also discloses a tunneling method, which includes using a tunneling machine to tunnel under three working conditions. Through the tunneling methods under three different working conditions, it can adapt to various emergencies in the construction process, and is convenient for construction. sequence.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a support system for roadheaders, a roadheader and a roadheading method. Background technique [0002] TBM (tunnel boring machine) needs supporting equipment to provide support and reaction force for the propulsion system of the TBM in the soft rock geological construction process, but the existing technology has the following problems: 1. The supporting force provided by the supporting equipment is insufficient, resulting in The excavation of the cutter head fails; 2. The external auxiliary equipment (such as the rear supporting facilities) connected to the roadheader is too heavy, and the roadheader cannot effectively drag the external auxiliary equipment forward, so that the step change cannot be realized; [0003] To sum up, there is an urgent need for a support system for a roadheader, a roadheader, and a roadheading method that can provide effective support and reaction...
