Problems solved by technology

The main reason is that the underground geological conditions are complex, the empty head distance is small, and the parallel operation of excavation and support cannot be realized.
Moreover, the bolt support method currently used has simple equipment and is mainly completed by manual labor.
[0004] At present, domestic coal machine manufacturers produce a wide variety of bolters with different structures. In domestic coal mines, there has been no successful use of roadheader airborne anchor protection devices. It is a long-term exploration, continuous innovation and improvement project

Abstract

The invention discloses an onboard anchoring device for a tunnelling machine, and belongs to the technical field of tunnelling machines. A sliding rail base is installed and fixed on a tunnelling machine body; two sides of the sliding rail base are provided with two propulsion oil cylinders; a sliding rail is installed on the sliding rail base and is provided with an anchor rod platform; two sidesof the anchor rod platform are independently provided with a drill arm and an anchor rod machine; the middle of the anchor rod platform is provided with a temporary support; a temporary supporting lifting and lowering oil cylinder is arranged between thee temporary support and the anchor rod platform; an operating platform is a parallel four-connecting-rod mechanism and can carry out horizontal lifting and lowering under the function of an oil cylinder; the front end of the drill arm and the front end of a supporting rod are connected with a gyration seat through two hinging points; a supporting rod oil cylinder is arranged below the supporting rod; and an anchor rod drilling machine and an anchor rod drilling machine fixing frame are connected through two oscillating oil cylinders. Afterthe onboard anchoring device and the tunnelling machine finish being installed, a tunnelling, anchor rod installation and temporary supporting integration operation can be realized for roadway tunnelling work.

Description

Technical field [0001] The invention relates to an on-board anchor protection device for a roadheader, belonging to the technical field of roadheaders. Background technique [0002] With the rapid development of my country's economy, the coal industry continues to develop in the direction of mechanization and automation, and comprehensive mechanized coal mining equipment is more and more widely used in coal production under various geological conditions. [0003] In the roadway excavation link, in addition to the improvement in the quality of the roadheader itself, the overall technological level is still lagging behind. The main reason is that the underground geological conditions are complicated and the empty roof distance is small, which makes it impossible to realize the parallel operation of tunneling and support. In addition, the currently adopted bolt support method has simple equipment and is mainly completed by manual labor. [0004] At present, the domestic coal mining ma...
