Description

Technical Field

[0001] This utility model relates to the field of hydraulic fracturing technology for deep holes in hard rock, and in particular to a positioning device for large-diameter ultra-deep boreholes based on hydraulic fracturing for deep holes in hard rock. Background Technology

[0002] In the mining process of high-gas outburst mines, in order to improve the efficiency of rock breaking, it is necessary to use the roadheader tunneling construction method based on hard rock deep hole hydraulic blasting fracturing to break the rock. 3 to 5 hydraulic blasting fracturing holes are used to provide fracture compensation space for the roadheader to cut hard rock. When drilling hydraulic blasting fracturing holes, in order to improve the drilling accuracy and facilitate drilling large-diameter ultra-deep boreholes, it is necessary to use a large-diameter ultra-deep borehole positioning device based on hard rock deep hole hydraulic blasting fracturing to pre-determine the drilling location. A search revealed that Chinese Patent CN117552722A discloses a fixed-point drilling device for blasting operations, belonging to the field of blasting operation technology. It includes a top seat and a base arranged vertically, connected by a connecting rod. The base has a fixing mechanism for fixing the entire device to the rock surface and a waist-shaped hole for the drill bit to pass through. The top seat has a drill bit rotation mechanism for controlling multiple drill bits to rotate circumferentially inside the top seat, a moving mechanism for controlling the vertical and horizontal movement of a moving seat inside the top seat, a drill bit locking mechanism for locking a drill bit rotated to one side of the moving seat, and a driving mechanism for driving the locked drill bit to rotate. The driving mechanism is slidably connected to the top of the moving seat in the vertical direction, and the drill bit locking mechanism is located on the driving mechanism. This invention solves the problem that current blasting operations are difficult to position on inclined rock surfaces, limiting drilling to a single specification.

[0003] The above-mentioned technical solution can only facilitate drilling and positioning on inclined rock surfaces. It cannot fully reveal the specific location of the positioning hole area by marking the hole while positioning it. This can easily lead to the problem that the positioning hole is not obvious enough, making it inconvenient for construction personnel to quickly find the positioning hole. It can also easily cause directional deviation when drilling deep holes, which is not conducive to fully improving the convenience and accuracy of construction. Utility Model Content

[0004] The above-mentioned technical solutions only facilitate drilling and positioning on inclined rock surfaces, but cannot fully reveal the specific location of the positioning hole area by marking the hole while positioning it.

[0016] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0017] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a large-diameter ultra-deep drilling positioning device based on hydraulic fracturing of deep holes in hard rock.

[0018] The specific technical solution includes a support column 1 and a positioning marker assembly 3; like Figure 1-4As shown, a linear cylinder 2 is installed inside the support column 1. The linear cylinder 2 can drive the support column 1 to extend and retract. The fixed end of the linear cylinder 2 is fixedly connected to the fixed end of the support column 1, and the telescopic end of the linear cylinder 2 is fixedly connected to the telescopic end of the support column 1. A positioning mark assembly 3 is installed on the support column 1. The positioning mark assembly 3 is used to improve the clarity of the positioning point. The positioning mark assembly 3 includes a support component and a coloring component. The support component includes a top plate 301, a pull rod 302, a fixing ring 303, and a pressure ring 304. The top plate 301... The top of the pull rod 302 is supported, the pull rod 302 supports the pressure ring 304, the fixing ring 303 supports the rotating drum 306 in the extension and retraction direction of the linear cylinder 2, the pressure ring 304 supports the ball 305 and can drive the ball 305 to move, the top plate 301 is fixedly sleeved on the extension and retraction end of the support column 1, the pull rod 302 is fixedly installed below the top plate 301, the fixing ring 303 is fixedly connected to the fixed end of the support column 1 and sleeved on the outside of the pull rod 302, and the pressure ring... 304 is fixedly installed below the pull rod 302. A ball bearing 305 is fixedly installed inside the pressure ring 304. The ball bearing 305 can press against the side wall of the threaded groove 4. The coloring components include a rotating drum 306, a pigment box 307, and a brush 308. The rotating drum 306 prevents the pigment box 307 from moving along the extension and retraction direction of the linear cylinder 2. The central axis of the rotating drum 306 coincides with the central axis of the drilling rig 5. The brush 308 can color the area around the positioning holes on the rock surface. The rotating drum 306 rotatably passes through the fixed ring 303. Inside the pressure ring 304, the outside of the rotating drum 306 is provided with a threaded groove 4, which can be connected to the ball 305. The ball 305 passes through the threaded groove 4. The paint box 307 is fixedly installed inside the rotating drum 306. The brush 308 is fixedly installed below the paint box 307. The center of the top plate 301 is fixedly installed with a drill 5. When the drill 5 is started, it can drill a positioning hole on the rock surface. The positioning hole can mark the position on the rock surface where a deep hole needs to be drilled. The drill 5 passes through the middle part of the rotating drum 306.

[0019] Place the base 7 on the rock surface where drilling is required. Using the handheld stabilizing positioning device, the bottom of the brush 308 contacts the rock surface. The pigment liquid inside the pigment box 307 wets the bristles of the brush 308. The linear cylinder 2 starts, causing the support column 1 to retract. The telescopic end of the support column 1 moves the top plate 301 and the drill rig 5 closer to the rock surface. The drill rig 5 starts drilling positioning holes on the rock surface. The movement of the top plate 301 moves the pull rod 302, which in turn moves the pressure ring 304. The pressure ring 304 moves the ball bearing 305, which presses against the inner wall of the threaded groove 4. The fixing ring 303, fixed by the fixed end of the support column 1, presses against the rotating drum 306. The support prevents the rotary drum 306 from moving along the direction of extension and retraction of the linear cylinder 2. Therefore, the rotary drum 306 can only drive the threaded groove 4 to rotate around the central axis of the drill rig 5. After being squeezed by the ball bearing 305, the threaded groove 4 can drive the rotary drum 306 to rotate around the central axis of the drill rig 5. The rotary drum 306 can drive the paint box 307 to rotate around the central axis of the drill rig 5. The paint box 307 can drive the brush 308 to brush paint on the rock surface of the positioning hole around the central axis of the drill rig 5. The structure formed by the paint brushed on the rock surface by the brush 308 is a hollow circle. The hollow circle completely surrounds the positioning hole and the distance from the edge to the center point of the positioning hole is the same. At this time, the positioning hole can be drilled and the paint can be brushed at the same time, which can significantly improve the clarity of the positioning hole.

[0020] like Figure 2 and Figure 4 As shown, a sealing plug 6 is inserted above the paint box 307. When the sealing plug 6 is opened, paint can be easily added to the paint box 307.

[0021] like Figure 1 and Figure 3 As shown, a base 7 is fixedly installed below the fixed end of the support column 1, and the base 7 can support and fix the fixed end of the support column 1.

[0022] like Figure 3 As shown, the bottom surface of the base 7 is fixedly equipped with an anti-slip cone 8. When the base 7 is placed on the rock surface, the anti-slip cone 8 is in contact with the rock surface. The anti-slip cone 8 can fully improve the friction between the base 7 and the rock surface.

[0023] like Figure 1 and Figure 3 As shown, a handle 9 is fixedly installed on the side wall of the fixed end of the support column 1. The positioning device is a small instrument. By gripping the handle 9 and pressing it toward the rock surface, the handle 9 can press the base 7 through the fixed end of the support column 1. The base 7 can press the rock surface through the anti-slip cone 8, which makes it convenient to fix the positioning device by hand.
