Description
Technical Field
The utility model relates to a TBM props boots technical field of system, especially indicates a swift current car device is prevented to inclined shaft TBM.
Background
When the open TBM is propelled, main push oil cylinders positioned on two sides of the main beam form a propulsion system, one end of the propulsion system is connected with the main beam, the other end of the propulsion system is connected with the supporting shoe, propulsion force is provided for the cutter head, reaction force of the cutter head is born and transmitted, and force is transmitted to the supporting shoe supported on the wall of the hole. And when the TBM changes steps, the supporting shoe is retracted, and the main thrust cylinder is retracted to prepare for the next tunneling stroke.
TBM is usually horizontal tunneling, and the phenomenon of vehicle sliding does not exist in the step changing process. The tunnel formed by the inclined shaft TBM forms a certain inclination angle with the horizontal plane, and the larger the inclination angle is, the larger the danger of the TBM sliding under the action of gravity is. Particularly, in the TBM step changing process, the supporting shoes in the TBM main machine area are completely retracted, the external force applied to the TBM equipment is only the friction force generated between the TBM equipment and the inclined shaft hole wall, and the TBM equipment is very easy to slip down under the influence of self gravity in this state.
The invention discloses an anti-slip self-locking propelling structure of a large-gradient inclined shaft tunnel boring machine, which is retrieved by the prior patent with application date of 20170713 and application number of CN201710568615.8, and comprises a cutter head, a shield, a main beam, a main push oil cylinder, a front support shoe, an auxiliary push oil cylinder, a rear support frame, a rear support shoe, a front support oil cylinder, a saddle frame, a connecting rod and a rear support oil cylinder, wherein the anti-slip self-locking propelling structure of the large-gradient inclined shaft tunnel boring machine is divided into three areas, namely a rigid propelling main body, a front support system and a rear support system, the cutter head is connected with the shield, and the shield is connected with the main beam; a main beam is installed in the saddle, two front supporting oil cylinders are respectively installed on two sides of the saddle and connected with the front supporting shoes, one end of a main push oil cylinder is connected with the front supporting shoes, and the other end of the main push oil cylinder is connected with the main beam; one end of the auxiliary push oil cylinder is connected with the rear support frame, and the other end of the auxiliary push oil cylinder is connected with the main beam.
Although the invention has the self-locking function, the rear supporting shoe oil cylinder and the rear supporting shoe are in a hinged structure, and when the rear supporting shoe oil cylinder drives the rear supporting shoe to extend and retract, the rear supporting shoe tends to rotate relative to the inner wall surface of the inclined shaft. When the rear supporting shoes after rotating are extruded to the inner wall of the inclined shaft, the rear supporting shoes cannot be directly and reliably attached to the inner wall of the inclined shaft due to the fact that the supporting surfaces of the rear supporting shoes are not parallel to the inner wall of the inclined shaft, and if the extending amount of the rear supporting shoe oil cylinder is improperly controlled, the risk of sliding exists.
In addition, the self-locking function of the invention depends on the normal work of the rear supporting oil cylinder, when the equipment is powered off or the pump station is damaged to cause that the oil cylinder cannot maintain pressure, the rear supporting shoe oil cylinder supporting the rear supporting shoe loses the function of supporting and jacking the rear supporting shoe, and the rear supporting shoe cannot continuously support the inner wall of the inclined shaft to cause the sliding. Therefore, the supporting function of the rear supporting shoe oil cylinder is completely depended on, and great potential safety hazard exists.
