Abstract
Description
Technical Field
[0001] The utility model belongs to the field of water exploration and drainage construction, in particular to a device for preventing a casing of a water exploration and drainage drilling hole from falling off in a mine. Background Art
[0002] Water exploration and release is a general term that includes water exploration and water release. Water exploration refers to the use of advanced exploration methods in the mining process to determine the specific spatial location and conditions of water bodies in the top and bottom plates, side walls and front of the mining face. Its purpose is to make necessary preparations for effectively preventing and controlling mine water hazards; water release refers to the use of safe methods such as drilling to release water after the situation is ascertained in order to prevent water hazards.
[0003] During the exploration and drainage operation in mines, it is necessary to install a borehole casing (also called a water-stop casing) at the drill hole. Since underground stress is relatively concentrated and has a strong destructive force, the damage to the borehole is relatively serious. The borehole casing breaks frequently, causing the borehole casing to easily fall off or be ejected from the borehole under high water pressure, causing injuries to construction workers on site underground. In addition, the leaked exploration and drainage water is uncontrolled, causing damage to the equipment and environment of the underground working surface, which is prone to safety accidents. Utility Model Content
[0004] The utility model aims to provide a device for preventing the casing of a borehole from falling off during mining and water exploration and drainage, and overcomes the shortcomings of the above-mentioned prior art, thereby effectively solving the safety problems caused by the use of the borehole casing.
[0005] The content of the utility model: A device for preventing the casing of a borehole from falling off during exploration and drainage of water in a mine, comprising a pad, a through hole being opened on the pad, a borehole casing being inserted in the through hole, a limit strip being vertically installed on the outer circumferential surface of the borehole casing, a clamping plate being installed on the top wall of the pad, a semi-closed clamping groove being formed between the pads, and fixing nails being arranged on the pad.
[0006] Furthermore, two of the limit strips are symmetrically installed on the outer circumferential surface of the drilling casing, and two of the clamping plates are symmetrically installed on the top wall of the pad.
[0007] Furthermore, the clamping plate is in a semi-arc shape.
[0008] Furthermore, a plurality of screw holes are evenly arranged on the clamping plate, and insertion holes matching the screw holes are arranged on the limiting strip, and bolts are screwed into the screw holes.
[0009] Furthermore, the outer circumferential surface of the drilling casing is slidably fitted with the inner circumferential surface of the through hole.
[0010] Furthermore, the pad is square, and mounting holes are provided at four top corners of the pad, and the fixing nails are inserted into the mounting holes.
[0011] The beneficial effects of the utility model are as follows: by installing the limit strip in the semi-enclosed slot formed between the pad and the clamping plate, the drilling casing can be quickly fixed to the pad, and then the pad is fixed to the bedrock of the tunnel. When the drilling casing breaks, the drilling casing can be effectively protected from falling off to avoid injuries to operators, ensure that the equipment and environment of the underground working surface are not damaged, and reduce the risk of safety accidents.

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:
[0017] like Figures 1 to 3 As shown, a device for preventing a borehole casing from falling off in a mine for water exploration and drainage comprises a backing plate 1, a through hole is formed on the backing plate 1, a borehole casing 2 is inserted into the through hole, a limit strip 3 is vertically installed on the outer circumference of the borehole casing 2, a clamping plate 4 is installed on the top wall of the backing plate 1, a semi-enclosed clamping groove is formed between the backing plate 1 and the clamping plate 4, a fixing nail 8 is arranged on the backing plate 1, two limit strips 3 are symmetrically installed on the outer circumference of the borehole casing 2, and the limit strips 3 are symmetrically installed on the outer circumference of the borehole casing 2. The top wall of the pad 1 is symmetrically equipped with two clamping plates 4, which are in a semi-arc shape. A number of screw holes 5 are evenly arranged on the clamping plates 4, and a socket 6 matching the screw holes 5 is arranged on the limiting strip 3. Bolts 7 are screwed in the screw holes 5. The outer circumferential surface of the drilling sleeve 2 is slidably fitted with the inner circumferential surface of the through hole. The pad 1 is square, and mounting holes are arranged at the four top corners of the pad 1, and the fixing nails 8 are inserted in the mounting holes.
[0018] Specifically, the limiting strip 3 is clamped in a semi-enclosed clamping groove formed between the backing plate 1 and the clamping plate 4, so that the drilling sleeve 2 can be quickly fixed to the backing plate 1 to prevent the drilling sleeve 2 from falling off.
[0019] During actual use, first insert the drilling sleeve 2 into the through hole opened in the pad 1, and align the two symmetrical limit strips 3 with the notches formed by the two clamping plates 4. At this time, rotate the drilling sleeve 2 so that the two symmetrical limit strips 3 are respectively screwed into the semi-closed clamping grooves formed between the pad 1 and the clamping plates 4. At this time, the drilling sleeve 2 is connected and fixed to the pad 1. At this time, install the drilling sleeve 2 into the drill hole, and fix the fixing nail 8 to the mine wall; when the screw hole 5 and the socket 6 are coaxial, the bolt 7 can be screwed in, thereby strengthening the connection and fixation between the drilling sleeve 2 and the pad 1.
[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
