Description

Technical Field

[0001] The utility model belongs to the technical field of mine support, and more specifically, particularly relates to a drilling and expanding device. Background Art

[0002] In mine tunnel support operations, it is necessary to use a drill to drill holes. After the drilling is completed, in order to improve the support efficiency, it is necessary to expand the upper side of the borehole, and then inject anchor grouting into the borehole. When expanding the borehole, it is necessary to use an expansion device, which is placed inside the borehole and rotates to grind and expand the hole.

[0003] According to CN201922191238.8, the utility model discloses a drilling and reaming device for mine support, including a fixed seat, the fixed seat is a cylindrical tube structure, the outside of the fixed seat is fixedly connected with a seat sleeve which is also a cylindrical tube structure, a motor is slidably connected between the circumferential inner wall of the seat sleeve and the circumferential outer wall of the fixed seat, a connecting shaft is fixedly connected to the output shaft of the motor, a reaming head is fixedly connected to the end of the connecting shaft, and a guide mechanism is arranged at the left end of the seat sleeve. The utility model is a drilling and reaming device for mine support with simple structure, good stability, high reaming efficiency and good effect.

[0004] Based on the above, the existing reaming device generally reams the borehole through a group of drill bit structures. Since the drill bit continuously grinds the borehole, the drill bit will become blunt after rotating the hole for a period of time. After the drill bit becomes blunt, the staff needs to take out the reaming device from the borehole, disassemble and install the drill bit from the device, and then put the reaming device into the borehole. The operation is cumbersome when the drill bit is frequently replaced. Utility Model Content
