TBM pushing mechanism structure and device

Abstract

The invention discloses a TBM pushing mechanism structure and a device. The pushing mechanism structure comprises a pushing mechanism and an anti-torsion spring plate arranged on the pushing mechanism. The device applying the pushing mechanism structure further comprises a front main beam, a hinge base, a tight support device, a left support shoe, a right support shoe and a pushing sliding beam. The front main beam and the pushing sliding beam are fixedly connected. The tight support device is arranged on the pushing sliding beam and can slide front and back along the pushing sliding beam. Theleft support shoe and the right support shoe are hinged and installed to the tight support device. One end of the pushing mechanism is rotationally connected with the front main beam, and the other end of the pushing mechanism is hinged to the corresponding left support shoe or right support shoe. The pushing mechanism structure and the device using the pushing mechanism are provided, the installing distance between upper-lower pushing mechanisms on each side of the front main beam can be reduced, accordingly, the space utilization rate above and below the pushing mechanism is increased, on one hand, design flexibility is improved, and on the other hand, large space is provided for manual auxiliary work.

Description

technical field [0001] The invention belongs to the technical field of roadheader construction machinery, and in particular relates to a TBM (hard rock roadheader) propulsion mechanism structure and device. Background technique [0002] In recent years, TBM (Tunnel Boring Machine) has been more and more widely used in underground engineering fields such as railway road tunnels, water conservancy and electric power transmission tunnels, and coal mine rock roadways. As a complex large-scale equipment integrating machinery, electricity, and hydraulics, TBM needs to complete various operations such as rock breaking, slag removal, support, and bottom slag removal during the construction process. The roadheader inevitably needs manual auxiliary operations during the continuous excavation process, and the propulsion mechanism of the TBM is located in front of the entire equipment, occupying a large space, especially for a small diameter TBM, the narrow space becomes an important fa...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new structure and device of the TBM propulsion mechanism, optimize the layout of the propulsion mechanism, save the structural space, improve the space utilization rate of the equipment, and provide convenience for manual auxiliary operations to solve the problems in the above-mentioned background technology. The anti-twist spring steel plate device of the proposed existing TBM is arranged between the propulsion mechanisms on each side, so the distance between the two propulsion mechanisms is relatively large, occupying the human work space on the upper and lower sides of the propulsion mechanism, and providing artificial assistance The problem that the homework has caused great inconvenience
