Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] Such as Figure 1-2 As shown, embodiment 1 is an open type TBM auxiliary shoe device, including a main beam 9 and a main shoe 10 arranged on the main beam 9, the main shoe 10 can adopt the existing shoe mechanism, the main shoe It is a single-groove shoe, which can well use the steel arch frame, and the auxiliary shoe structure does not affect the use of the main shoe. A saddle frame 12 is slidingly arranged on the main beam 9, and the saddle frame can...

Abstract

The invention discloses an open-type TBM auxiliary supporting shoe device which solves the problems of limited supporting shoe areas and single supporting shoe mode of an open-type TBM supporting shoemechanism in the prior art. The open-type TBM auxiliary supporting shoe device comprises a main beam and a main supporting shoe arranged on the main beam; one side of the main supporting shoe is connected with the main beam through a propulsion oil cylinder, an auxiliary supporting shoes are arranged on other side of the main supporting shoe, the auxiliary supporting shoes are connected through connecting pieces, and the connecting pieces are provided with auxiliary supports corresponding to the main beam. According to the open-type TBM auxiliary supporting shoe device, the auxiliary supporting shoes and the main supporting shoe adopted to use cooperatively, and expanding and retracting independently can further be carried out, when a surrounding rock is good, the auxiliary supporting shoes are retracted, and the main supporting shoe is used for supporting the wall of a tunnel tightly to provide propulsion reaction force and driving reaction torque required for TBM propulsion; and inthe cases of a weak surrounding rock and a broken surrounding rock, the surrounding rocks can withstand less pressure, and the main supporting shoe and the auxiliary supporting shoes are used at the same time to support the wall of the tunnel tightly, so that the contact area between the supporting shoes and the surrounding rock is increased, and the contact pressure between the supporting shoes and the surrounding rock is reduced.

Description

technical field [0001] The invention relates to the technical field of open TBM, in particular to an auxiliary shoe device for an open TBM. Background technique [0002] TBM is the abbreviation of full-face hard rock tunnel boring machine. It is a special equipment for tunnel excavation and plays an important role in the construction of mountain tunnels and urban subways. According to the working principle and structural form of TBM, TBM includes shield TBM and open TBM. Open TBM can be divided into Kai TBM and main beam TBM according to different support forms. The main beam TBM is mainly composed of cutter head, shield, drive assembly, propulsion system, rear support, belt conveyor and other auxiliary systems. As the key part of the open TBM, the propulsion system is mainly used to transmit the torque generated by the cutter head rotating to excavate the rock wall and the thrust of the whole machine to move forward. The support form of the main beam type TBM is a horizo...
