Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0021] It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", et...

Abstract

The invention discloses a reversible drilling box for a roof bolter. The reversible drilling box comprises a fixed seat arranged on a roof bolter sliding rail, a drilling box body capable of being reversed relative to the fixed seat, and a reversing oil cylinder for pushing the drilling box body to be reversed, wherein the drilling box body is connected with the fixed seat through a first hinge shaft; one end of the reversing oil cylinder is connected with the drilling box body through a second hinge shaft; the other end of the reversing oil cylinder is connected with the fixed seat through athird hinge shaft; and the drilling box body is driven by the reversing oil cylinder to be reversed left and right around the first hinge shaft. According to the roof bolter, the problem of replacinga drill rod and an anchor rod when the anchor rod is constructed in a small roadway is solved, when the anchor rod is constructed through the roof bolter, the roof bolter does not need to be moved when the anchor rod is inserted, the problem that the replacing efficiency of the drill rod and the anchor rod is low is solved, the anchor rod is inserted more conveniently, the anchoring efficiency isimproved, the secondary eye finding time is shortened, and the anchor rod supporting speed is increased.

Description

technical field [0001] The invention relates to the field of coal mine mining equipment, in particular to a reversible drill box for a rock bolt drill. Background technique [0002] At present, bolting technology is mostly used in underground coal mines, and pneumatic or hydraulic bolting rigs are used to construct bolts. Hydraulic bolting rigs have the advantages of large torque, high speed, and fast construction speed, which is the mainstream trend of current coal mine bolting construction equipment. However, due to the limited equipment space in underground coal mines, the stroke of the rock bolter is relatively short, so it is impossible to drill holes in one operation, and brazing operations are required, that is, drilling with a small stroke at one time, and drilling all the holes in the second brazing construction. In the existing technology, the drilling rig needs to be removed for brazing, which increases the secondary positioning process of the drilling rig, prolon...
