Description

Technical Field

[0001] The utility model relates to the technical field of rock drills, in particular to a deep-hole rock drill. Background Technique

[0002] A rock drill is a tool used to directly mine stone materials. It drills blast holes in rock formations so that explosives can be placed to blast the rock, thereby completing the mining of stone materials or other stonework projects. In addition, the rock drill can also be converted into a breaker to break hard layers such as concrete. Rock drills can be divided into four categories according to their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills, and hydraulic rock drills. Rock drills work according to the principle of impact crushing; when working, the piston makes high-frequency reciprocating motions, continuously impacting the shank end. Under the action of the impact force, the bit in the shape of a pointed wedge crushes the rock and drills into a certain depth, forming a dent. After the piston retracts, the drill rod rotates by a certain angle. When the piston moves forward and impacts the shank end again, a new dent is formed. The fan-shaped rock mass between the two dents is sheared by the horizontal component force generated by the bit. The piston continuously impacts the shank end, and compressed air or pressurized water is continuously input from the central hole of the drill rod to discharge the rock slag outside the hole, that is, a circular drill hole with a certain depth is formed;

[0003] Some existing rock drills are held by hand or fixed or supported by simple mechanical structures, which are not only inconvenient to use, but also have low safety. At the same time, the drilling angle cannot be adjusted well, and it is difficult for workers to control the same drilling angle for a long time, which is not convenient for drilling deep holes;

[0004] Therefore, a deep-hole rock drill is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a deep-hole rock drill to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A deep-hole rock drill includes a workbench. A pair of support plates are fixedly connected to the lower surface of the workbench. A U-shaped frame is slidably connected to the inner side wall of the support plate. A bidirectional lead screw is rotatably connected to the inner side wall of the support plate. A pair of sliders are threadedly connected to the outer side wall of the bidirectional lead screw. A first connecting rod is hinged between the outer side wall of the slider and the upper surface of the U-shaped frame. A pair of rollers are installed on the lower surface of the support plate. A support seat is fixedly connected to the upper surface of the workbench. An angle plate is rotatably connected to the inner side wall of the support seat. A rock drilling mechanism is fixedly connected to the outer side wall of the angle plate. An adjusting frame is fixedly connected to the upper surface of the workbench. A threaded rod is rotatably connected to the inner side wall of the adjusting frame. A push-pull block is threadedly connected to the outer side wall of the threaded rod. A pair of second connecting rods are hinged to the right side wall of the angle plate.
