Description

Technical Field

[0001] The present invention relates to the field of mine detection equipment, and in particular to a mine boring peeping device with uniform speed propulsion. Background Art

[0002] During the coal mining process, in order to effectively prevent the occurrence of gas accidents, gas is usually extracted by drilling to reduce the gas emission from the coal seam. By drilling in the corresponding area of the coal seam, a borehole peephole is used to observe the crack development in the borehole to better guide the implementation of the next gas extraction operation.

[0003] To further understand the separation of the coal seam roof during the excavation of the coal mine roadway or the coal face mining, on-site technicians or scientific researchers tend to use a borehole peeping device for detection. However, when conducting borehole peeping in coal mines, due to some rock debris adhering to the borehole wall, it is easy to cause the rock debris blocks to cover the lens during the advancement of the borehole probe, which is not conducive to continuing the borehole peeping work. The advancement speed has a significant impact on the borehole peeping quality during the advancement process. Therefore, it is an urgent problem to invent a mine borehole peeping device with a uniform speed propulsion that can self-clean the lens, which can not only solve the problem of the borehole rock debris covering the probe but also can uniformly advance the borehole probe to achieve effective peeping of the borehole. Summary of the Invention

[0004] In order to facilitate the automatic cleaning of the lens and at the same time be able to push the probe into the borehole at a uniform speed, the present invention provides a mine boring peeping device with uniform speed propulsion.

[0005] The mine boring peeping device with uniform speed propulsion provided by the present invention adopts the following technical solutions:

[0006] A mine boring peeping device with uniform speed propulsion includes a hydraulic propulsion mechanism, a connection mechanism, and a peeping mechanism connected in sequence. The hydraulic propulsion mechanism includes a hydraulic cylinder, and a threaded hole for cooperating with a drilling rig is opened at the end of the cylinder body of the hydraulic cylinder. The connection mechanism is detachably connected to the end of the piston rod of the hydraulic cylinder; the peeping mechanism includes a probe body, a detection lens is provided at one end of the probe body, and a plurality of cleaning nozzles are provided at a position of the probe body close to the lens. The cleaning nozzles are circumferentially distributed outside the detection lens, and the end of the probe body far from the detection lens is detachably connected to the connection mechanism.

[0007] By adopting the above technical solution, the cleaning nozzle is connected to an external air source for supplying air source to the cleaning nozzle. The cleaning nozzle starts to jet air when the detection lens is blocked by drilling cuttings, effectively cleaning the surface of the detection lens, preventing debris from blocking the detection lens. The probe body and the connecting mechanism are assembled together, and then the connecting mechanism is assembled with the end of the piston rod of the hydraulic cylinder. The piston rod of the hydraulic cylinder extends, which can evenly push the detection lens into the drilling hole, ensuring the clarity of the captured image quality, realizing effective peeping of the drilling hole, and achieving convenient automatic cleaning of the lens and at the same time being able to evenly push the probe into the drilling hole.

[0008] Optionally, the connecting mechanism is formed by connecting the first and last ends of multiple connecting rods. Two connecting blocks are symmetrically arranged at one end of the connecting rod. The connecting blocks are fixedly connected to the outer side wall of the connecting rod. A plugging groove is formed in the middle of the connecting rod. At the end of the connecting rod away from the connecting block, there are connecting plates corresponding to the connecting blocks one by one. One end of the connecting plate close to the connecting block is fixedly connected with a plugging block, and the plugging block is used for plugging into the plugging groove. A positioning component is arranged between the connecting plate and the connecting block.

[0009] By adopting the above technical solution, when assembling the connecting mechanism, inserting the plugging block of one connecting rod into the plugging groove of another connecting rod can make the ends of the two connecting rods abut. Finally, the adjacent two connecting rods can be fixed through the connecting component.

[0010] Optionally, the connecting component includes a connecting ring arranged on the connecting block; the connecting component further includes a slider slidably connected to the connecting plate. One end of the slider is rotatably connected with a plugging rod. The end of the plugging rod away from the hinged end is fixedly connected with a positioning rod. A guiding arc surface is formed on the positioning rod, and an inclined surface is formed at the end of the positioning rod.

[0011] By adopting the above technical solution, when assembling and fixing adjacent connecting rods, rotating the plugging rod to insert the positioning rod at the end of the plugging rod into the connecting ring. The inclined surface facilitates the insertion of the positioning rod into the connecting ring, and the guiding arc surface can facilitate the clamping of the positioning rod in the connecting ring, thereby fixing the connecting plate and the connecting block together.

[0012] Optionally, a sliding groove is formed in the connecting plate, and the slider is slidably connected to the sliding groove. One end of the slider close to the plugging block is fixedly connected with a compression spring, and the end of the compression spring away from the slider is fixedly connected to the inner wall of the sliding groove.

[0013] By adopting the above technical solution, pulling the slider by the plugging rod to compress the compression spring makes the connection between the connecting rod and the connecting ring more stable. When the positioning rod is manually pushed outwards to disengage from the connecting ring, the tension of the compression spring pushes the slider and the plugging rod to move in the reverse direction, facilitating the disassembly between adjacent two connecting rods.

[0014] Optionally, a connecting plate is not provided at the end of the connecting rod for connecting to the probe body, and a threaded column is threadedly connected to the end of the connecting rod, a connecting interface is provided on the probe body, and the threaded column and the probe body are threadedly connected.

[0015] By adopting the above technical solution, the threaded column fixes the probe body and the connecting rod, thereby facilitating the fixation of the probe body and the connecting rod, and the threaded connection facilitates the disassembly and installation between the probe body and the connecting rod.

[0016] Optionally, the end of the piston rod of the hydraulic cylinder is fixedly connected with a placement groove, which is used for the connection rod to be inserted, and the placement grooves are symmetrically opened on both sides of the placement groove, which are used for the connection block on the connecting rod to be inserted, and the side walls of the placement groove are threadedly connected with bolts, which are used to fix the connecting rod and the placement groove.

[0017] By adopting the above technical solution, the connecting rod is inserted into the placement groove, and then the connecting rod and the placement groove are fixed by bolts, and the plug-in block is inserted into the clearance groove, which can ensure the direction of the connecting rod and facilitate the fixation between adjacent connecting rods.

[0018] Optionally, a connecting rod clamp is provided on the hydraulic cylinder; the connecting rod clamp includes a connecting rod one symmetrically hinged on both sides of the hydraulic cylinder, the end of the connecting rod one away from the connecting rod one is hinged with a clamping arm, the end of the clamping arm away from the connecting rod one is fixedly connected with a clamping plate, the two clamping plates are both arranged in an arc shape, a cylinder is hinged on the connecting rod one, the cylinder body of the cylinder is hinged on the connecting rod one, and the piston rod end of the cylinder is hinged on the clamping arm.

[0019] By adopting the above technical solution, when assembling the connecting rod, the connecting rod without a connecting plate at one end is installed on the connecting interface of the probe body. Next, continue to assemble the connecting rod. First, fix the probe body and the connecting rod through the threaded post. The hydraulic cylinder pushes the connecting rod and the probe body into the hole. The piston rod of the air cylinder retracts, so that the clamping plate fixes the connecting rod. Then, the piston rod of the hydraulic cylinder retracts, inserts one end of the new connecting rod into the placement groove, and fixes the other end to the already assembled connecting rod. Insert the insertion block of the connecting plate into the insertion groove of the connecting block, fix the placement groove of the connecting rod through the bolt, rotate the insertion rod, insert the positioning rod into the connecting ring, and at the same time pull the slider to compress the compression spring through the insertion rod, then the adjacent two connecting rods can be fixed. The piston rod of the hydraulic cylinder extends, pushing the connecting rod and the probe body to move into the hole; after that, the piston rod of the air cylinder retracts, and the two clamping plates fix the later assembled connecting rod. Then loosen the bolt, and the piston rod of the hydraulic cylinder retracts, so that the connecting rod is separated from the placement groove, and continue to install the next connecting rod. As the connecting rods are assembled, the detection lens is evenly pushed into the drilling hole through the hydraulic cylinder; when disassembling the connecting rod, the clamping arm clamps the connecting rod spaced from the hydraulic cylinder. At this time, the connecting rod connected to the hydraulic cylinder is inserted into the placement groove and fixed to the placement groove through the bolt. Then, pull the insertion rod to compress the compression spring again, and pull the connecting rod out of the connecting ring until the connecting rod is separated from the connecting ring. The tension of the compressed compression spring moves the slider away from the insertion block, facilitating the release of the fixation between adjacent two connecting rods; then, the piston rod of the hydraulic cylinder retracts, and the connecting rod connected to the hydraulic cylinder is removed; finally, the piston rod of the hydraulic cylinder extends, and at the same time the piston rod of the air cylinder retracts, insert the connecting rod into the placement groove of the hydraulic cylinder, and then fix the connecting rod and the placement groove through the bolt. The piston rod of the hydraulic cylinder retracts, and the connecting rod inserted into the placement groove of the hydraulic cylinder is removed, and so on, the connecting rods are disassembled one by one in an orderly manner.

[0020] Optionally, a plurality of supplementary light lamps are arranged at a position of the probe body close to the detection lens, and the supplementary light lamps are distributed circumferentially along the probe body.

[0021] By adopting the above technical solution, since the drilling hole is pitch-dark without a light source, the supplementary light lamps provide a light source for peeping into the drilling hole, illuminate the hole wall of the drilling hole, and facilitate the detection lens to clearly collect the situation of the inner wall of the drilling hole.

[0022] Optionally, rubber anti-collision sleeves are fixedly connected to the outer side walls of the probe body close to both ends.

[0023] By adopting the above technical solution, the rubber anti-collision sleeves protect the probe body from being damaged by collision and prevent the detection lens from rubbing against the hole wall of the drilling hole when the probe is working. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0033] The following further elaborates on the present invention in conjunction with the attached Figure 1-8 drawings.

[0034] An embodiment of the present invention discloses a mine - use uniformly - advancing borehole peeping device. Referring to Figure 1 , a mine - use uniformly - advancing borehole peeping device includes a hydraulic propulsion mechanism 3, a connection mechanism 2, and a peeping mechanism 1. The hydraulic propulsion mechanism 3 is used to connect with a drill rig. One end of the connection mechanism 2 is connected to the hydraulic propulsion mechanism 3, and the other end is connected to the peeping mechanism 1. The hydraulic propulsion mechanism 3 pushes the connection mechanism 2 and the peeping mechanism 1 to extend into the borehole so that the peeping mechanism 1 can collect pictures inside the borehole wall.

[0035] Referring to Figure 2 and Figure 3, the peeping mechanism 1 includes a probe body 11. One end of the probe body 11 is provided with a detection lens 111, which mainly collects images inside the drilled hole. The end part inside the detection lens 111 is arranged in an arc shape. The arc surface design enables the accumulated rock debris to slide along the arc surface, ensuring the normal operation of the detection lens 111. At a position of the probe body 11 close to the detection lens 111, a plurality of supplementary light lamps 12 are provided. The supplementary light lamps 12 are evenly distributed along the circumferential direction of the probe body 11. Since it is pitch-dark and there is no light source inside the drilled hole, the supplementary light lamps 12 provide light source for peeping into the drilled hole, illuminating the hole wall of the drilled hole and facilitating the clear collection of the inner wall situation of the drilled hole by the detection lens 111. At a position of the probe body 11 close to the lens, a plurality of cleaning nozzles 13 are provided. The cleaning nozzles 13 are evenly distributed circumferentially outside the detection lens 111. The cleaning nozzles 13 are connected to an external air source for providing air source to the cleaning nozzles 13. The cleaning nozzles 13 start to jet air when the detection lens 111 is blocked by the rock debris in the drilled hole, effectively cleaning the surface of the detection lens 111.

[0036] At one end of the probe body 11 far from the detection lens 111, a connection interface 14 and an information transmission line interface 15 are provided. The connection interface 14 is used to connect with the mechanism 2, and the connection mechanism 2 is directly installed on the probe tail by a knob. The information transmission line interface 15 is used to connect a data transmission line. Protective covers 16 are threadedly connected to both ends of the probe body 11. When the probe is not working, the protective covers 16 isolate the detection lens 111, the connection interface 14, and the information transmission line interface 15 from the outside world, thus playing a role in protecting the detection lens 111, the connection interface 14, and the information transmission line interface 15. Rubber anti-collision sleeves 17 are fixedly connected to the outer side walls of the probe body 11 near both ends. The rubber anti-collision sleeves 17 protect the probe body 11 from being damaged by collision and prevent the detection lens 111 from rubbing against the hole wall of the drilled hole when the probe is working.

[0037] Refer to Figure 4 and Figure 5 , the connection mechanism 2 is composed of a plurality of segmented connecting rods 21. The connecting rods 21 are connected end to end, which can extend the detection lens 111 deeper into the drilled hole. The structures of the connecting rods 21 are the same. Here, only one connecting rod 21 is taken as an example. At one end of the connecting rod 21, two connecting blocks 22 are symmetrically arranged. The connecting blocks 22 are fixedly connected to the outer side wall of the connecting rod 21. An insertion slot 221 is provided in the middle of the connecting rod 21. The insertion slot 221 extends inward from the end. A connecting ring 222 is fixedly connected to the end of the connecting block 22 far from the insertion slot 221.

[0038] Refer to Figure 6 and Figure 7Two connecting plates 23 are symmetrically arranged at the other end of the connecting rod 21, and the connecting plates 23 and the connecting blocks 22 correspond one to one. The end of the connecting plate 23 close to the connecting block 22 is fixedly connected with a plug-in block 231, and the plug-in block 231 is used to be plugged into the plug-in groove 221; a sliding groove 232 is opened in the connecting plate 23, and a slider 233 is slidably connected in the sliding groove 232, and a clamping spring 234 is fixedly connected to the end of the slider 233 close to the plug-in block 231, and the end of the clamping spring 234 away from the slider 233 is fixedly connected to the inner wall of the sliding groove 232.

[0039] Reference Figure 5 and Figure 7 The top of the slider 233 is rotatably connected to a plug rod 235, and the end of the plug rod 235 away from the hinged end is fixedly connected to a positioning rod 236, and a guide arc surface 238 is provided on the positioning rod 236, and an inclined surface 237 is provided at the end of the positioning rod 236. The inclined surface 237 facilitates the positioning rod 236 to be inserted into the connecting ring 222, and the guide arc surface 238 can facilitate the positioning rod 236 to slide in the connecting ring 222 until the connecting ring 222 abuts against the plug rod 235. At the same time, the slider 233 is pulled by the plug rod 235 to compress the clamping spring 234, so that the connection between the connecting rod 21 and the connecting ring 222 is more stable. When the positioning rod 236 is manually pushed outward to disengage from the connecting ring 222, the tension of the clamping spring 234 pushes the slider 233 and the plug rod 235 to move in the opposite direction, which is convenient for the disassembly between the two adjacent connecting rods 21.

[0040] Reference Figure 4 and Figure 6 The end of one of the connecting rods 21 is not provided with a connecting plate 23, and the end of the connecting rod 21 is threadedly connected with a threaded column 24, which is used to be threadedly connected to the connecting interface 14 on the probe body 11, thereby fixing the probe body 11 and the connecting rod 21.

[0041] Reference Figure 1 and Figure 8 The hydraulic propulsion mechanism 3 includes a hydraulic cylinder 31. A threaded hole 311 is provided at the cylinder end of the hydraulic cylinder 31. The threaded hole 311 is used to connect the hydraulic cylinder 31 to the drilling rig. After the drilling rig is completed, the drilling bit is removed and the knob of the hydraulic cylinder 31 is turned on the propulsion rod of the drilling rig, which can effectively ensure that the propulsion direction of the drilling peep device is consistent with the drilling direction. The piston rod end of the hydraulic cylinder 31 is fixedly connected with a placement groove 32. The placement groove 32 is used for the connection rod 21 to be inserted. The placement groove 32 is symmetrically provided with a clearance groove 321 on both sides. The clearance groove 321 is used for the connection block 22 on the connection rod 21 to facilitate the connection rod 21 to be stably inserted into the placement groove 32. The side wall of the placement groove 32 is threadedly connected with a bolt, and the bolt is used to fix the connection rod 21 and the placement groove 32.

[0042] A connecting rod holder 33 is provided on the hydraulic cylinder 31. The connecting rod holder 33 includes a first connecting rod 331 symmetrically hinged on both sides of the hydraulic cylinder 31. One end of the first connecting rod 331 away from the first connecting rod 331 is hinged with a clamping arm 332. A clamping plate 333 is fixedly connected to the end of the clamping arm 332 away from the first connecting rod 331. Both clamping plates 333 are arc-shaped. The two clamping plates 333 can abut against the outer wall of the connecting rod 21 to fix the connecting rod 21. A cylinder 334 is hinged on the first connecting rod 331. The cylinder body of the cylinder 334 is hinged on the first connecting rod 331, and the end of the piston rod of the cylinder 334 is hinged on the clamping arm 332.

[0043] When assembling the connecting rod 21, first fix the probe body 11 and the connecting rod 21 through the threaded column 24. The hydraulic cylinder 31 pushes the connecting rod 21 and the probe body 11 into the hole. The piston rod of the cylinder 334 retracts, so that the clamping plates 333 fix the connecting rod 21. Then, the piston rod of the hydraulic cylinder 31 retracts, inserts one end of the new connecting rod 21 into the placement groove 32, and fixes the other end to the already assembled connecting rod 21, so that the insertion block 231 of the connecting plate 23 is inserted into the insertion groove 221 of the connecting block 22. Fix the placement groove 32 of the connecting rod 21 with bolts. Rotate the insertion rod 235 so that the positioning rod 236 is inserted into the connecting ring 222. At the same time, pull the slider 233 through the insertion rod 235 to compress the compression spring 234, and the adjacent two connecting rods 21 can be fixed. The piston rod of the hydraulic cylinder 31 extends to push the connecting rod 21 and the probe body 11 to move into the hole. After that, the piston rod of the cylinder 334 retracts, and the two clamping plates 333 fix the later assembled connecting rod 21. Then loosen the bolts, and the piston rod of the hydraulic cylinder 31 retracts to separate the connecting rod 21 from the placement groove 32, and continue to install the next connecting rod 21. As the connecting rod 21 is assembled, the detection lens 111 is evenly pushed into the drilling hole through the hydraulic cylinder 31.

[0044] The implementation principle of a mine - used uniformly - advancing borehole peeping device in an embodiment of the present invention is as follows: Remove the protective covers 16 at both ends of the probe body 11. Install the connecting rod 21 without a connecting plate 23 at one end on the connecting interface 14 of the probe body 11. Next, continue to assemble the connecting rod 21. First, fix the probe body 11 and the connecting rod 21 through the threaded column 24. The hydraulic cylinder 31 pushes the connecting rod 21 and the probe body 11 into the hole. The piston rod of the air cylinder 334 retracts, so that the clamping plate 333 fixes the connecting rod 21. Then, the piston rod of the hydraulic cylinder 31 retracts, insert one end of a new connecting rod 21 into the placement groove 32, and fix the other end to the already - assembled connecting rod 21. Insert the insertion block 231 of the connecting plate 23 into the insertion groove 221 of the connecting block 22, and fix the connecting rod 21 to the placement groove 32 with bolts. Rotate the insertion rod 235 so that the positioning rod 236 is inserted into the connecting ring 222. At the same time, pull the slider 233 by the insertion rod 235 to compress the compression spring 234, then the adjacent two connecting rods 21 can be fixed. The piston rod of the hydraulic cylinder 31 extends to push the connecting rod 21 and the probe body 11 to move into the hole. After that, the piston rod of the air cylinder 334 retracts, and the two clamping plates 333 fix the later - assembled connecting rod 21. Then loosen the bolts, and the piston rod of the hydraulic cylinder 31 retracts to separate the connecting rod 21 from the placement groove 32. Continue to install the next connecting rod 21. As the connecting rods 21 are assembled, the detection lens 111 is evenly pushed into the borehole through the hydraulic cylinder 31.

[0045] When the probe body 11 exits the hole, the clamping arm 332 clamps the connecting rod 21 spaced from the hydraulic cylinder 31. At this time, the connecting rod 21 connected to the hydraulic cylinder 31 is inserted into the placement groove 32 and fixed to the placement groove 32 with bolts. After that, pull the insertion rod 235 to compress the compression spring 234 again, and pull the connecting rod 21 outwards from the connecting ring 222 until the connecting rod 21 is separated from the connecting ring 222. The tension of the compressed compression spring 234 moves the slider 233 in a direction away from the insertion block 231, facilitating the release of the fixation between adjacent two connecting rods 21. Then, the piston rod of the hydraulic cylinder 31 retracts to remove the connecting rod 21 connected to the hydraulic cylinder 31. Finally, the piston rod of the hydraulic cylinder 31 extends, and at the same time, the piston rod of the air cylinder 334 retracts. Insert the connecting rod 21 into the placement groove 32 of the hydraulic cylinder 31, and then fix the connecting rod 21 and the placement groove 32 with bolts. The piston rod of the hydraulic cylinder 31 retracts to remove the connecting rod 21 inserted into the placement groove 32 of the hydraulic cylinder 31. And so on, the connecting rods 21 are disassembled one by one in an orderly manner.

[0046] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
