Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and in particular to a new device that facilitates precise drilling assistance in coal mines, especially a drilling assistance tool for mining. Background Technology

[0002] In coal mines, equipment is frequently suspended to ensure normal operation. Currently, when suspending equipment in coal mines, it is usually necessary to first drill holes in the walls of the mine roadway. To ensure the accuracy of the drilling position, a measuring tape is currently used for positioning. However, the working conditions in underground coal mine roadways differ from those on the surface. The roadways are uneven and rugged, making it difficult to control the dimensions and depth during drilling. This increases the difficulty, time and labor costs, and significantly raises safety hazards during drilling.

[0003] Currently, there are many types of equipment for drilling holes in mines in existing technology. For example, patent document CN214091702U discloses a drilling device for coal mines, whose main structure includes a base, a fixing block fixedly connected to the left side of the top of the base, a top plate fixedly connected to the top of the fixing block, a first motor fixedly connected to the top of the top plate, a screw fixedly connected to the bottom end of the first motor shaft extending through to the outside of the top plate, the bottom end of the screw being movably connected to the top of the base, a movable block threadedly connected to the surface of the screw, the left side of the movable block extending through to the inside of the fixing block, and the inside of the fixing block... A guide rod is fixedly connected to the base, and the surface of the guide rod is movably connected to the movable block. A second motor is fixedly connected to the right side of the movable block, and a rotating rod is fixedly connected to the bottom end of the second motor shaft. A drill bit is fixedly connected to the bottom end of the rotating rod through the outside of the base. Fixed sleeves are movably connected to both sides of the rotating rod surface. A pressure block is fixedly connected to the top of the other side of the fixed sleeve, and an insert rod is fixedly connected to the bottom of the pressure block. A fixed rod is movably connected to the inside of the fixed sleeve, and a spring is movably connected to the surface of the fixed rod. Both sides of the spring are movably connected to the fixed sleeve, and both ends of the fixed rod through the outside of the fixed sleeve are fixedly connected to a stop block.

[0004] As can be seen from the above structure, it is mainly suitable for vertical drilling in coal mines, but it cannot be directly applied to the drilling of horizontal holes on the sidewalls of roadways, nor can it achieve precise control over the drilling accuracy of horizontal hanging holes.

[0005] Therefore, this invention optimizes and improves upon the problems existing in mining hoisting drilling in the prior art, and proposes a mining drilling auxiliary tool with a simple structure and easy use, in order to better solve the problems existing in the prior art. Summary of the Invention

[0006] To solve one of the aforementioned technical problems, the present invention adopts the following technical solution: a mining drilling auxiliary tool, which is used in conjunction with a suspended drilling device. The mining drilling auxiliary tool includes an operating plate base, with an end abutment screwed into the threaded holes at both ends of the operating plate base. The inner ends of each end abutment are used to abut against the sidewall of the roadway. A drilling positioning component is provided in the middle of the left side of the operating plate base. When it is necessary to position the next drilling position, the drilling positioning component is initially positioned at the previous drilling position. A sliding groove is provided on the operating plate base on the right side of the drilling positioning component, extending along its length. Scale lines are provided on the outer surface of the operating plate base on both sides of the sliding groove. An adjustment and locking mechanism is provided through the sliding groove. When it is necessary to position the next drilling position, the adjustment and locking mechanism is used to position the drilling position.

[0007] In any of the above embodiments, it is preferred that the end abutment includes an end threaded post screwed into the end threaded hole at the corresponding position, the inner end of the end threaded post abutting against the roadway sidewall at the corresponding position, and an adjusting handwheel fixedly installed at the outer end of the end threaded post.

[0008] In any of the above embodiments, it is preferred that the drilling positioning component includes a positioning external threaded sleeve screwed into the positioning threaded hole of the operating plate seat at the corresponding position, an internal thread is provided on the inner side wall of the positioning external threaded sleeve, a drilling positioning ring is detachably screwed into the inner cavity of the positioning external threaded sleeve, and an external thread is provided on the outer side wall of the drilling positioning ring that engages with the internal thread at the corresponding position.

[0009] In any of the above embodiments, it is preferred that the adjustment locking mechanism includes an adjustment screw tube fixedly installed in the sliding channel, and an abutment friction nut is screwed into the upper and lower parts of the external thread section of the adjustment screw tube, respectively. The inner ends of the two abutment friction nuts respectively abut against the upper and lower surfaces of the operating plate seat on both sides of the top and bottom of the sliding channel at the current position.

[0010] In any of the above embodiments, it is preferred that a measuring and positioning stud is threaded into the inner cavity of the adjusting screw tube, and a positioning mark pen is installed in the inner end mounting cavity of the measuring and positioning stud. When the positioning mark pen is pressed against the side wall of the tunnel where the next borehole needs to be drilled, it will leave a mark on it.

[0011] In any of the above embodiments, it is preferred that a marking operation handwheel is fixedly connected to the outer end of the measuring positioning stud.

[0012] In any of the above embodiments, it is preferred that an operating handle is installed on the operating panel base.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This tool has a simple overall structure and can be used with existing mine hoisting and drilling equipment. When in use, it can achieve precise control of the distance between adjacent boreholes, ensuring the accuracy of the drilling position.

[0014] 2. The entire tool is simple and quick to operate. By pre-adjusting the distance between the positioning and locking mechanism and the center of the drilling positioning component, the distance between two adjacent drilling holes can be controlled, which can effectively ensure accurate positioning before drilling and ensure the flexibility, speed and accuracy of operation when drilling adjacent holes.

[0015] 3. When using this tool, it can be installed on the drill rod of the mine hoisting drilling equipment. Positioning is achieved manually by holding the operating handle, allowing for rapid drilling of the first hole. After the first hole is drilled, the distance between the positioning locking mechanism and the center of the drilling positioning component can be adjusted to position the next adjacent hole. After positioning, the mine hoisting drilling equipment is moved, and the entire tool is rotated 180° to ensure the measuring positioning stud is inserted into the previously drilled hole. At this point, a positioning outer threaded sleeve is also fitted onto the drill rod. Moving the positioning outer threaded sleeve to the marked position allows for quick drilling again. The overall operation is simple, fast, and provides accurate drilling positioning. Attached Figure Description

[0021] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore merely examples and should not be used to limit the scope of protection of the present invention. The specific structure of the present invention is as follows: Figures 1-3 As shown in the image.

[0022] Example 1: A mining drilling auxiliary tool, which is used in conjunction with a suspended drilling equipment. The mining drilling auxiliary tool includes an operating plate base 1. An end abutment is screwed into the threaded holes 2 at both ends of the operating plate base 1. The inner end of each end abutment is used to abut against the side wall 3 of the roadway. A drilling positioning component is provided in the middle of the left side of the operating plate base 1. When it is necessary to position the next drilling position, the drilling positioning component is initially positioned at the previous drilling position. A sliding groove 4 is provided on the operating plate base 1 on the right side of the drilling positioning component, which is arranged along its length. Scale lines 5 are provided on the outer surface of the operating plate base 1 on both sides of the sliding groove 4. An adjustment and locking mechanism is provided through the sliding groove 4. When it is necessary to position the next drilling position, the adjustment and locking mechanism is used to position the drilling position. The mining drilling auxiliary tool of this invention can be used in conjunction with existing mining hoisting drilling equipment. Before drilling the tunnel sidewall 3, the drilling positioning component can be sleeved onto the outer wall of the drill rod. Simultaneously, the extension length of the end abutment needs to be pre-adjusted so that the inner end of the end abutment can abut against the tunnel sidewall 3 at different locations. At this time, the operator can use the operating handle 16 to position the entire tool. The mining hoisting drilling equipment is then started, and the drill rod is used to drill into the rock wall. The end abutment serves two purposes: first, to ensure the stability of the overall positioning when the tool is held by hand, by abutting the inner end of the end abutment against the corresponding tunnel sidewall 3; second, by controlling the abutment of the inner end of the end abutment, the distance between the inner end of the end abutment and the operating plate seat 1 can be controlled, thereby ensuring the maximum depth of the drill rod when drilling inwards and preventing excessive drilling. After the current drilling is completed, the pre-operated positioning and locking mechanism, in conjunction with the scale line 5 on it, can control the interval distance between the next drilling hole and the current drilling hole, thereby ensuring a suitable center distance between adjacent drilling holes and ensuring the accuracy of positioning when installing equipment later.

[0023] In any of the above embodiments, preferably, the end abutment includes an end threaded post 6 screwed into the end threaded hole 2 at a corresponding position. The inner end of the end threaded post 6 abuts against the roadway sidewall 3 at the corresponding position, and an adjusting handwheel 7 is fixedly installed at the outer end of the end threaded post 6. During operation, the end abutment mainly works by rotating the adjusting handwheel 7 to cause the inner end of the corresponding end threaded post 6 to extend inward, ultimately achieving the abutment of the inner end of the end threaded post 6 against the roadway sidewall 3 at the corresponding position.

[0024] In any of the above embodiments, preferably, the drilling positioning component includes a positioning external threaded sleeve 9 screwed into the positioning threaded hole 8 of the operating plate seat 1 at a corresponding position. An internal thread is provided on the inner side wall of the positioning external threaded sleeve 9. A drilling positioning ring 10 is detachably screwed into the inner cavity of the positioning external threaded sleeve 9. An external thread is provided on the outer side wall of the drilling positioning ring 10 that engages with the internal thread at the corresponding position. When in use, the drilling positioning component is sleeved onto the outer side wall of the drill rod to be drilled, and is engaged by the drilling positioning ring 10. The drilling positioning ring 10 can be pre-replaced according to the thickness of different drill rods.

[0025] In any of the above embodiments, preferably, the positioning and locking mechanism includes a positioning screw tube 11 fixedly installed in the sliding groove 4. An abutment friction nut 12 is screwed onto the upper and lower parts of the external threaded section of the positioning screw tube 11, respectively. The inner ends of the two abutment friction nuts 12 respectively engage with and abut against the upper and lower surfaces of the operating plate seat 1 on both sides of the top and bottom of the sliding groove 4 at the current position. The positioning and locking mechanism is mainly used to adjust the center distance between the two drill holes as needed. When in use, the positioning and locking mechanism is directly sleeved on the outer wall of the current drill rod to achieve coaxial setting with the drill rod and ensure initial positioning.

[0026] In any of the above embodiments, a preferred embodiment is that a measuring and positioning stud 13 is threaded into the inner cavity of the adjusting screw tube 11, and a positioning marker 14 is installed in the inner end mounting cavity of the measuring and positioning stud 13. When the positioning marker 14 is pressed against the tunnel sidewall 3 where the next borehole needs to be drilled, it will leave a mark on it. During adjustment, the adjusting screw tube 11 can be pre-loosened to achieve the adjustment and displacement of the entire adjusting and locking mechanism, ultimately achieving the purpose of adjusting to the correct position according to the scale line 5. After adjustment, the entire adjusting and locking mechanism is locked at the current position of the operating plate seat 1 by screwing on the corresponding abutment friction nut 12. The positioning marker 14 provided here can directly abut against the tunnel sidewall 3 to mark the fixed point.

[0029] During operation, the end abutment is mainly operated by rotating the adjusting handwheel 7 to drive the inner end of the corresponding end threaded post 6 to extend inward, so that the inner end of the end threaded post 6 abuts against the roadway sidewall 3 at the corresponding position.

[0030] In any of the above embodiments, it is preferred that the drilling positioning component includes a positioning external threaded sleeve 9 screwed into the positioning threaded hole 8 of the operating plate seat 1 at the corresponding position, an internal thread is provided on the inner side wall of the positioning external threaded sleeve 9, a drilling positioning ring 10 is detachably screwed into the inner cavity of the positioning external threaded sleeve 9, and an external thread is provided on the outer side wall of the drilling positioning ring 10 that screws into the internal thread at the corresponding position.

[0033] The adjustment and locking mechanism can be adjusted according to the center distance between the two boreholes.

[0035] When adjusting, the adjusting screw tube 11 can be loosened in advance to realize the adjustment and displacement of the entire adjusting and locking mechanism, and finally achieve the purpose of adjusting to the correct position according to the scale line 5. After the adjustment is in place, the entire adjusting and locking mechanism is locked at the current position of the operating plate seat 1 by screwing on the corresponding abutting friction nut 12.

[0039] In any of the above embodiments, it is preferred that an operating handle 16 is installed on the operating panel base 1.

[0040] The stability of the entire tool's positioning can be controlled by operating the handle 16.

[0041] Specific working principle: The mining drilling auxiliary tool of this invention can be used in conjunction with existing mining hoisting drilling equipment. Before drilling the tunnel sidewall 3, the drilling positioning component can be sleeved onto the outer wall of the drill rod. Simultaneously, the extension length of the end abutment needs to be pre-adjusted so that the inner end of the end abutment can abut against the tunnel sidewall 3 at different locations. At this time, the operator can use the operating handle 16 to position the entire tool. The mining hoisting drilling equipment is then started, and the drill rod is used to drill into the rock wall. The end abutment serves two purposes: first, to ensure the stability of the overall positioning when the tool is held by hand, by abutting the inner end of the end abutment against the corresponding tunnel sidewall 3; second, by controlling the abutment of the inner end of the end abutment, the distance between the inner end of the end abutment and the operating plate seat 1 can be controlled, thereby ensuring the maximum depth of the drill rod when drilling inwards and preventing excessive drilling. After the current drilling is completed, the pre-operated positioning and locking mechanism, in conjunction with the scale line 5 on it, can control the interval distance between the next drilling hole and the current drilling hole, thereby ensuring a suitable center distance between adjacent drilling holes and ensuring the accuracy of positioning when installing equipment later.

[0042] This tool has a simple overall structure and can be used with existing mine hoisting drilling equipment. During use, it allows for precise control of the distance between adjacent boreholes, ensuring accurate drilling positioning. The tool is simple and quick to operate. By pre-adjusting the distance between the positioning and locking mechanism and the center of the borehole positioning component, the distance between two adjacent boreholes can be controlled, effectively ensuring precise positioning before drilling and guaranteeing flexibility, speed, and accuracy during adjacent drilling operations. This tool can be installed on the drill rod of mine hoisting drilling equipment, and simultaneously... Positioning is achieved by manually holding the operating handle 16, allowing for rapid drilling of the first hole. After the first hole is drilled, the distance between the positioning locking mechanism and the center of the drilling positioning component can be adjusted to position the next adjacent hole. After positioning, the mine hoisting drilling equipment is moved, and the entire tool is rotated 180° to ensure that the measuring positioning stud 13 is inserted into the previously drilled hole. At this time, the drilling rod is also fitted with a positioning outer threaded sleeve 9. Moving the positioning outer threaded sleeve 9 to the marked position allows for quick completion of the drilling operation. The overall operation is simple, fast, and the drilling positioning is accurate.
