[0029] Working process: The main structure of the present invention is based on the research and development of the hydraulic anchor bolter of the side of the anchor mining machine, which mainly utilizes its small size and outstanding practical application effect; the fixed part is to connect its mounting base 2 by a lateral rotating shaft, and the bottom of the simple hydraulic drilling rig main body 3 is suspended in the air, which can be used for both fixing and movement. At the same time, the mounting base 2 is changed to a steel structure central axis connection, which greatly increases its ability to provide a reverse force; the driving part is to move and drive the horizontal propulsion cylinder 5 and the anchor bolter slideway 14, which realizes stepless continuous movement and simplifies the mobile system for easy repair and maintenance; and the swing angle of the original simple hydraulic drilling rig main body 3 used by the side anchor bolter of the rotating part is not more than 10°, that is, its support range is relatively limited. In order to achieve a larger range of support coverage, a separate rotary hydraulic motor 4 is added to the side of the bottom of the simple hydraulic drilling rig main body 3, so that the swing angle of the simple hydraulic drilling rig main body 3 is increased to 120°, which greatly improves its support coverage, and finally forms the current flexible performance, fast drilling speed, simple operation, and space occupation. A small open TBM is equipped with a large swing angle stepless self-moving simple hydraulic anchor bolter. When the device is used, the fixed sleeve 8 and the support rod 7 can be connected by the first nut 17, bolt 18 and fixed gasket 15, and then the anti-skid pad 19 can be used to prevent the fixed sleeve 8 from sliding after fixation. Then the mounting plate 9 is fixed to the bottom side of the machine body 1. At this time, the strength of the device can be improved by the connecting rod 11 and the reinforcement rod 12. At the same time, when one of the top cones 20 is damaged, The second nut 25 can be screwed to separate the second nut 25 from the threaded head 24, and then the top cone 20 is pushed to make the limiting slide bar and the limiting slide 26 leave the assembly frame 23, and then the new top cone 20 is taken out, and the limiting slide 26 is inserted into the assembly frame 23. When the limiting slide 26 enters the assembly frame 23, the second nut 25 can contact the threaded head 24 to achieve the effect of fixing the top cone 20. When one of the top cones 20 is damaged, only the damaged top cone 20 needs to be replaced. The structure is simple and practical.
