Hard rock tunnel boring machine (TBM) main beam and saddle frame sliding rail device

Abstract

The invention relates to a hard rock tunnel boring machine (TBM) main beam and saddle frame sliding rail device. The device comprises a main beam component and a saddle frame sliding rail component, wherein the main beam component is composed of a main beam and a main beam sliding rail abrasion resistant cutting board, and the saddle frame sliding rail component is composed of saddle frame sliding rail copper plates, a saddle frame upper cover, a saddle frame upper part and a saddle frame lower part. The main beam component serves as a fixed part, the saddle frame sliding rail component serves as a moving part, and the moving part can be moved along the fixed part under the action of a propulsion oil cylinder. According to the hard rock TBM main beam and saddle frame sliding rail device, the technical effects that loading is large, the borne force of the beam is uniform when the beam bears a lateral load, the structure of the lower portion of the device is compact, so other parts are easy to install and arrange, installation and adjustment are easy, and when the main beam bears torque, the torque is distributed uniformly are achieved.

Description

technical field [0001] The invention relates to a tunnel boring machine construction equipment, in particular to a tunnel boring machine hard rock TBM main beam and a saddle frame slide rail. Background technique [0002] In the field of tunnel boring machine TBM construction, the main girder is generally a box-shaped main girder represented by Robbins, and the structure of the saddle guide rail is shown in figure 1 , This structural form has the following disadvantages: the load is heavier on the lower side of the main beam, the lower structure is too large, the installation and adjustment are difficult, and the torque is borne by the lower part of the beam when it is torsion. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the hard rock TBM main beam and saddle frame slide rail device in the prior art, and solve the shortcomings of most main beams such as large space occupation, complicated installation and adjustment operation...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned shortcomings of the hard rock TBM main beam and saddle frame slide rail device in the prior art, and solve the shortcomings of most main beams such as large space occupation, complicated installation and adjustment operations, and heavy load on the lower side, the present invention provides a hard rock TBM Rock TBM main beam and saddle frame slide rail device, which includes main beam parts, which are composed of main beam and main beam slide rail wear-resistant plate. The main beam adopts a square box structure with grooves processed at the four corners. The rail wear-resistant plates are respectively installed on the grooves and can be disassembled to form the fixed part of the main beam; the saddle frame slide rail parts: composed of the saddle frame slide rail copper plate, the saddle frame upper cover, the saddle frame upper part and the saddle frame lower part, constitute A structure nested with the structure after the main beam is installed and can slide along the copper plate of the saddle frame slide rail, and the copper plate of the saddle frame slide rail is respectively installed on the upper cover of the saddle frame and the upper part of the saddle frame, and can be disassembled; the main beam part is a fixed part , the saddle frame slide rail part is the moving part, the moving part can move along the fixed part under the action of the propulsion cylinder, and also includes the support shoe and the tension cylinder
