Problems solved by technology

[0003] The following defects exist in the prior art. The first structure occupies a large space in the vertical direction of the tunnel, and the space in the vertical direction of the tunnel is just the working space of the workers. Therefore, this structure is not conducive to the work of the workers and the transportation of materials. The work efficiency is greatly affected; although the second structure increases the working space, since the main beam and the support shoe system are connected as a whole through guide rails, the main beam has no freedom of movement in the horizontal and vertical directions, and the whole machine equipment cannot be used in excavation. The direction adjustment function is completed in the process, and the structure of this form is complex, and the vibration of the whole machine is relatively large after the guide rail is worn.

Abstract

The invention provides an open-type full-face rock ripper, comprising a cutterhead (14), a shield (15), a driving component (16), a girder (17), a thrust cylinder (18), a support boot and a saddle rack system (19), wherein the girder (17) comprises a first girder (2), a second girder (6), a rear support (9) and a lead rail (7); the first girder (2), the second girder (6) and the rear support (9) are connected through a bolt. By adopting the open-type full-face rock ripper, the height of the upper plane of the girder is reduced; an upper work space of the girder is expanded; the stress of the section of the girder is reduced by the open-type full-face rock ripper under the same load; the capacity of the girder for resisting bending moment and torque is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an open full-face rock boring machine. Background technique [0002] Full-face rock tunnel boring machine (TBM) is a large-scale tunnel boring equipment integrating mechanical, electronic, hydraulic, laser and other technologies. It 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, and open TBM is also called main beam TBM. The open TBM is mainly composed of cutter head, shield, drive assembly, main beam, propulsion and support shoe system and other auxiliary systems. The main beam is the key component of the open TBM, its main function is to transmit the torque generated by the rotating cutter head to excavate the rock wall and the forward thrust of the whole machine, and also to provide guidance for the forward and backward movement of the su...
