Supporting shoe device and TBM with same

Abstract

The invention discloses a supporting shoe device and a TBM. The supporting shoe device comprises a tight supporting shield, an upper supporting shoe oil cylinder and a lower supporting shoe oil cylinder and further comprises a support fixedly arranged on the tight supporting shield; the support is provided with a hollow structure reducing the occupied section space of the tight supporting shield; at least one of the upper supporting shoe oil cylinder and the lower supporting shoe oil cylinder comprises a first oil cylinder set and a second oil cylinder set; the two ends of the first oil cylinder set are connected with the left end of the support and a left supporting shoe; and the two ends of the second oil cylinder set are connected with the right end of the support and a right supporting shoe. According to the supporting shoe device and the TBM, the upper supporting shoe oil cylinder or the lower supporting shoe oil cylinder is split into the two-section type oil cylinder sets, the middle portions of the two-section type oil cylinder sets are connected through the support of the hollow structure, the two oil cylinder sets are connected with the corresponding supporting shoes correspondingly, the hollow structure of the middle portion of the support can be used for personnel operation and the like, the situation that the oil cylinders occupy the middle space is avoided, and the section space, occupied by a supporting shoe system, of the tight supporting shield can be effectively reduced while the using stability of the oil cylinders is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel excavation, and more specifically, relates to a gutter device. Furthermore, the present invention also relates to a TBM comprising the above-mentioned gutter device. Background technique [0002] With the development of national science and technology and economy, roadheaders are widely used in tunnel construction of water conservancy and hydropower, rail transit, and municipal engineering. [0003] At present, the form of the traditional double-shield roadheader's support shoes is generally a horizontal arrangement of the upper and lower sets of support shoe oil cylinders, such as figure 1 as shown, figure 1 It is a schematic diagram of the double-shield roadheader stretcher system in the prior art. Two sets of stretcher cylinders 02 are extended simultaneously to make the left and right stretcher 01 of the brace shield 06 tighten the cave wall, providing counterforce for the tunneling of the ro...

AI Technical Summary

Problems solved by technology

Due to the large cross-sectional space occupied by the two sets of shoe cylinders 02, some double-shield roadheaders with small cross-sections are greatly restricted in terms of personnel passage, electrical and hydraulic piping and wiring, and the layout of the main engine belt conveyor.
