Problems solved by technology

Reduce the service life of equipment and affect the progress of project engineering
Aiming at this phenomenon, the manufacturer adopts the method of setting anti-rotation block on the support shoe device. Although this device prevents the large-angle deflection of the single-cylinder support shoe, it causes the direct contact between the anti-rotation block and the shield tail, and serious damage occurs during the movement. wear and tear

Embodiment Construction

[0021] see Figure 1-6 A new anti-twist device for the propulsion system of the shield machine is shown, which includes a hydraulic power unit, a jack, and a shoe device 4, and the hydraulic power unit is located in the hydraulic station of the second trailer. The oil inlet pipe and the oil return pipe are connected with the propulsion cylinder, and the action of the propulsion cylinder is controlled by the control valve group. The cylinder block at the front end of the propulsion cylinder is pushed against the middle shield partition, and the piston rod end of the propulsion cylinder is in contact with the spherical surface of the shoe. The shoe device 4 is then supported on the segment. When the propulsion cylinder advances, the reaction force generated by the piston rod acting on the assembled segment is transmitted to the cutter head, so that the cutter head is pushed forward while rotating. However, due to the influence of the reaction force of the cutting face of the c...

Abstract

The invention discloses a novel anti-twist device for a stretcher shoe of a shield machine propulsion system, which is characterized in that it comprises a hydraulic power unit, a jack, and a stretcher device. Single cylinder anti-twist device. The structure of the device is simple and flexible, which completely solves the phenomenon that the boots scrape the tail of the shield, reduces the wear of the boots on the tail of the shield, improves the service life and working efficiency of the shield body, and saves construction costs.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering, and relates to a novel anti-rotation device for a spreader shoe of a shield machine propulsion system. Background technique [0002] The shield machine is a special construction machine for tunneling, and the thrust required for the tunneling of the shield machine is provided by the propulsion system. The propulsion system of the shield machine is composed of hydraulic power unit, jack, shoe support device, etc., and is one of the important power systems of the shield machine. The jack transmits the force to the tunnel segment through the support shoe, and the shield machine moves forward under this reaction force, and the shield body is rotated due to the reaction force of the cutting face of the cutter head, and the good positional relationship between the support shoe and the shield tail changes. The boot scrapes and grinds the inner wall of the tail of the shield. Thereby acceler...
