Abstract
Description
Technical Field
[0001] The invention relates to the field of coal mine water prevention and control, and in particular to a roof drilling tool fixing device. Background Art
[0002] In the mine water prevention and control work and surrounding rock stress research, the purpose of draining water or installing equipment is often achieved through construction drilling. Small-angle drilling or bottom plate holes are more convenient to construct, while large-angle drilling or roof vertical holes require the use of specific drilling rigs. Such drilling rigs are often large in size and cannot adapt to narrow construction environments, which has certain limitations. Although the small drilling rig has a small body, the drilling rig structure is simple. When drilling holes in the roof, as the length of the drill rod increases, the weight of the drill rod also increases. When the weight of the drill rod is greater than the friction of the surrounding rock, the drill rod is easy to jump out and injure people, causing personal injury.
[0003] Therefore, a top plate drilling tool fixing device is proposed. Summary of the invention
[0004] The purpose of the present invention is to provide a top plate drilling tool fixing device, which can firmly fix the drilling tool in the hole to prevent the drill rod from jumping out and injuring people, causing personal injury, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a top plate drilling tool fixing device, comprising a device outer sleeve and an orifice tube, the device outer sleeve being welded to the upper end of the orifice tube, and both sides of the outer surface of the device outer sleeve are penetrated and threadedly connected with self-tapping fastening bolts, one end of which is fixedly connected with a fastening handle, and the opposite ends of the two self-tapping fastening bolts are tightly provided with fixing cava, and supporting slide rails are penetrated at both ends of the fixing cava, and a return spring is sleeved on the middle position of the outer surface of the supporting slide rail.
[0006] By using the top plate drilling tool fixing device, the drilling tool in the hole can be firmly fixed to prevent the drill rod from jumping out and injuring people, causing personal injury.
[0007] Preferably, the fixed cava can move left and right on the supporting slide rail, and the supporting slide rail passes through the device jacket. The number of the supporting slide rails is four, which are symmetrically placed in pairs. The return spring is located between the two fixed cava, and the elastic coefficient of the return spring is 8N / MM.
[0008] The fixed slips can fix the drill pipe.
[0009] Preferably, a fixed steel plate is fixedly connected to the outer surface of the orifice tube near the upper end, and a fixed anchor rod is penetrated and threadedly connected to the outer surface corner of the fixed steel plate. The orifice tube and the device jacket are both hollow inside, and the orifice tube is located directly below the device jacket.
[0010] The fixed anchor rods, fixed steel plates and orifice pipes are used to fix the entire device to the tunnel roof.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The top plate drilling tool fixing device can be used to securely fix the drilling tool in the hole to prevent the drill rod from jumping out and injuring people, causing personal injury. When using it, first, insert the orifice pipe into the pre-drilled hole to fix it, then push the drill rod into part of the orifice pipe, rotate the tightening handle clockwise to drive the self-tapping tightening bolt to spiral forward, and the self-tapping tightening bolt acts on the two fixing slips to make them close to each other, clamp the drill rod, loosen the drill rig clamp, connect the second drill rod, use the drill rig clamp to fix the second drill rod, rotate the tightening handle counterclockwise, loosen the fixing slip, and the fixing slip automatically rebounds to the original position due to the action of the return spring, and the drill rig drills the second drill rod, and so on, to drill the top plate drill rod, so that the drill rod can be fixed when the length of the drill rod is increased, to prevent the drill rod from jumping out and injuring people, causing personal injury.
