Large-swing-angle stepless self-moving type simple hydraulic roof bolter used in cooperation with open-type TBM

Abstract

The invention relates to the technical field of TBMs (tunnel boring machines), in particular to a large-swing-angle stepless self-moving type simple hydraulic roof bolter matched with an open-type TBM. The large-swing-angle stepless self-moving type simple hydraulic roof bolter comprises a machine body, a mounting base and a tunneling device, supporting rods are arranged at the four corners of the upper side of the tunneling device and connected with the tunneling device through screws, and the supporting rods are arranged on the bottom side of the machine body; the supporting rod is connected with the machine body through a screw, one side of the upper end of the machine body is connected with the supporting frame, the supporting frame is connected with the horizontal thrust oil cylinder, the horizontal thrust oil cylinder is connected to one side of the mounting base, and the mounting base is slidably connected to the upper surface of the machine body. A non-fixed mode can be changed into a semi-fixed mode, more sufficient reverse acting force is provided for the anchor rod machine during supporting construction, and a hydraulic push chain mode is changed into a roof bolter sliding way and a horizontal thrust oil cylinder, so that stepless continuous movement is achieved, a movement system is simplified, and repair and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of TBM, in particular to a large-swing-angle stepless self-moving simple hydraulic bolter for an open-type TBM. Background technique [0002] When the open TBM is used for underground roadway excavation, the cutting section is a perfect circle. Its built-in hydraulic bolter for support has a large volume, which leads to a small occupation space for personnel, and can only accommodate one person for support work, which cannot realize the collaborative construction of more than two people, and the support efficiency is low; in addition, it adopts Handle operation, the whole operation process is relatively complicated, and it is impossible to realize the coal mine support requirements that are easy to understand and easy to operate; in addition, in order to ensure that it can be supported vertically to the roadway wall, a ring-shaped gear track is used to ensure the running track of the hydraulic bolter. The r...

Its built-in hydraulic bolter for support has a large volume, which leads to a small occupation space for personnel, and can only accommodate one person for support work, which cannot realize the collaborative construction of more than two people, and the support efficiency is low; in addition, it adopts Handle operation, the whole operation process is relatively complicated, and it is impossible to realize the coal mine support requirements that are easy to understand and easy to operate; in addition, in order to ensure that it can be supported vertically to the roadway wall, a ring-shaped gear track is used to ensure the running track of the hydraulic bolter. The reason shows that it cannot achieve continuous linear operation, and it cannot be supported according to the established row spacing between supports. It is inevitable that there will be errors.
