Description

Technical Field

[0001] This invention belongs to the field of mining equipment technology, and specifically provides a multi-drill bit switching mining device. Background Technology

[0002] In mining and tunneling, drilling rigs are the primary tools for rock breaking, and rock boreholes are formed by the drilling rig's drill bit breaking the rock. The size and quality of the drill bit vary in their adaptability to different rock types, significantly impacting drilling quality, speed, and cost. Current technologies cannot achieve efficient drill bit switching or seamless connection between the drill bit and the tunneling pipe, and the speed of changing drill bits in deep boreholes is slow, severely affecting construction progress. Therefore, it is necessary to develop a drilling rig that integrates efficient drill bit changing and rapid drill rod connection.

[0003] Chinese invention patent CN115075731A discloses a vertical drilling device for ore mining, comprising a drilling equipment body, a drilling sinking device, a wrap-around drilling device, an azimuth adjustment device, and a moving shock absorption component.

However, the prior art cannot realize the replacement of drill bits and is not suitable for deep drilling operations. Therefore, this invention provides a multi-drill bit switching mining device.

[0021] 1. This invention designs a docking mechanism and a replacement mechanism.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Reference Figures 1 to 9 A multi-drill bit switching mining device includes a docking mechanism 1, a changing mechanism 2, a continuing mechanism 3, drill bits 4 and tunneling pipes 5. Multiple drill bits 4 are mounted on the changing mechanism 2, and multiple tunneling pipes 5 are mounted on the continuing mechanism 3.

[0037] The docking mechanism 1 is used to install the tunneling pipe 5 and the drill bit 4, as well as to connect the two tunneling pipes 5.

[0038] The replacement mechanism 2 is used to place the drill bit 4, and by rotating it, the position of the drill bit 4 is adjusted, which, together with the docking mechanism 1, completes the connection and replacement of the drill bit 4 and the tunneling pipe 5.

[0039] The splicing mechanism 3 is used to place the tunneling pipe 5 and adjusts the position of the tunneling pipe 5 by rotation, and works with the docking mechanism 1 and the replacement mechanism 2 to complete the splicing of the tunneling pipe 5.

[0040] The docking mechanism 1 includes a bracket 101, a docking component, and a mating rod 104. The docking component is assembled on the bracket 101, and the mating rod 104 is fixedly installed in the middle of the front surface of the bracket 101. The left and right rear ends of the bracket 101 are symmetrically integrally formed with vertical plates.

[0041] Support 101 is the overall support structure for this multi-drill bit switching mining device.

[0042] The docking assembly enables the docking, connection, and replacement of the tunneling pipe 5 with the drill bit 4 or other tunneling pipes 5.

[0043] The replacement mechanism 2 includes a replacement component, a self-locking component one, a self-locking component two, a positioning component, and a replacement disc 204. The replacement component is mounted on the vertical plate, and the replacement disc 204 is fixedly installed at the output end of the replacement component. The surface of the replacement disc 204 is evenly provided with drill bit placement slots, and the drill bit 4 is placed in the drill bit placement slots. The self-locking component one is mounted on the side of the drill bit placement slots on the surface of the replacement disc 204. The front surface side end of the bracket 101 is fixedly installed with a replacement vertical plate 205. The self-locking component two is mounted on the replacement vertical plate 205, and the self-locking component two works in conjunction with the self-locking component one. The positioning component is mounted on the outer surface of the replacement vertical plate 205.

[0044] Replace the component to adjust the position of drill bit 4, placing drill bit 4 in the position to mate with the tunneling pipe 5.

[0045] Self-locking component one is used to limit the position of drill bit 4. Self-locking component two works in conjunction with self-locking component one. Together, they are used to release the restriction on drill bit 4, after which drill bit 4 can be connected to tunneling pipe 5.

[0046] The number of drill bit placement slots on the replacement disc 204 is unlimited, and different numbers of drill bit placement slots on the replacement disc 204 can be selected according to the actual application.

[0047] The drill bit 4 placed on the replacement disc 204 can be of different sizes.

[0048] After the drill bit 4 is released from its restraints, the positioning component clamps and fixes it to facilitate the docking of the drill bit 4 and the tunneling pipe 5. In addition, the positioning component is also used to clamp and fix the tunneling pipe 5 during the continuation of the tunneling pipe 5.

[0049] The continuing mechanism 3 includes a moving component, a power component, a clamping component, and a continuing drum 305. The moving component is mounted on the rear surface of the support 101, the power component is mounted on the side wall of the moving component, the continuing drum 305 is rotatably mounted inside the moving component, and the continuing drum 305 is fixedly installed at the output end of the power component. The outer surface of the continuing drum 305 is uniformly fixedly mounted with a clamping seat 306 and a clamping component, and the clamping component is used in conjunction with the mating rod 104. The tunneling pipe 5 is placed inside the clamping seat 306.

[0050] The moving component is used to move the continuing mechanism 3 toward the docking mechanism 1, thereby making the tunneling pipe 5 on the continuing drum 305 coaxial with the drill bit 4 that needs to be docked or the tunneling pipe 5 that needs to be continued, so as to carry out subsequent connection work.

[0051] The power unit is used to drive the continuous rotating drum 305 to rotate, thereby adjusting the position of the tunneling pipe 5.

[0052] Normally, the clamping assembly keeps the tunneling pipe 5 clamped in the clamping seat 306 to prevent it from falling off when the connecting drum 305 rotates. When performing docking or connecting work, it works with the mating rod 104 to fix the tunneling pipe 5 in place. Then, the tunneling pipe 5 can be connected to the docking turntable 106, and then docking or connecting work can be carried out.

[0053] The mounting bracket 306 has a U-shaped structure and is made of a material with low rigidity, which allows its sidewalls to bend under force. When pressure is applied to its outer wall, it will bend inward, thereby limiting or fixing the tunneling pipe 5.

[0054] Specifically, such as Figure 3 As shown, the docking assembly includes a docking slide 102, a lead screw 103, a docking belt 105, a docking turntable 106, a docking motor 107, a docking slide plate 108, and a docking pulley 109. The front ends of the left and right surfaces of the bracket 101 are integrally formed with docking slide support plates and protruding plates. The two docking slides 102 are fixedly installed between the upper ends of the docking slide support plates. The docking slide plate 108 is movably mounted on the docking slide 102. The docking turntable 106 and the docking pulley 109 are rotatably mounted on the upper and lower ends of the inner surface of the docking slide plate 108, respectively. The docking turntable 106 is placed on the docking slide 102. The lead screw 103 is fixedly installed between the protruding plates. The docking pulley 109 is rotatably mounted on the lead screw 103 through a thread. The docking belt 105 is wound between the docking turntable 106 and the docking pulley 109. The docking motor 107 is fixedly installed on the outer surface of the docking slide plate 108. The docking turntable 106 is fixedly installed at the output end of the docking motor 107.

[0055] An arc-shaped plate is provided at the upper end of the docking slide support plate. Two docking slides 102 are respectively installed at both ends of the arc-shaped plate. The outer surface of the docking turntable 106 is attached to the two docking slides 102, and the angle formed by the two docking slides 102 and the axis of the docking turntable 106 is 45°, which realizes auxiliary support for the docking turntable 106. The docking slides 102 also play the role of supporting and guiding the docking slide plate 108.

[0056] Since the lead screw 103 is fixed on the convex plate, when the docking pulley 109 rotates under the action of the docking motor 107, it will move on the lead screw 103, thereby driving the docking slide plate 108, the docking motor 107 and the docking turntable 106 to move. Therefore, the docking turntable 106 can rotate and move at the same time, so that it can be threadedly connected to the tunneling pipe 5. And after the docking motor 107 rotates in the opposite direction, the docking turntable 106 can be separated from the docking motor 107.

[0057] Specifically, the drill bit 4 is provided with internal threads, the two ends of the tunneling pipe 5 are provided with internal threads and external threads respectively, and the docking turntable 106 is provided with external threads.

[0058] The drill bit 4 is connected to the tunneling pipe 5, the tunneling pipe 5 is connected to each other, and the tunneling pipe 5 is connected to the docking turntable 106 by threads.

[0059] Specifically, such as Figure 4 As shown, the replacement assembly includes a replacement motor 201, a replacement belt assembly 202, and a replacement connecting rod 203. The replacement motor 201 is fixedly installed on the inner surface of the vertical plate. The replacement belt assembly 202 is assembled on the outer surface of the vertical plate. The replacement belt assembly 202 consists of a replacement pulley and a replacement belt. The replacement pulley is assembled at the output end of the replacement motor 201. The replacement connecting rod 203 is rotatably assembled between the two vertical plates. The replacement connecting rod 203 is connected to the replacement pulley through the replacement belt. The replacement disc 204 is fixedly installed on the replacement connecting rod 203.

[0060] After the replacement motor 201 is started, it drives the replacement connecting rod 203 to rotate through the replacement belt assembly 202, which in turn drives the replacement disc 204 to rotate, so that the drill bit 4 on the replacement disc 204 can be rotated to a horizontal position above the positioning slide rail 208 for docking.

[0061] Specifically, such as Figure 4 , Figure 6 and Figure 7 As shown, the self-locking assembly includes a self-locking spring 214, a self-locking base 215, a self-locking slide 216, a self-locking clamping plate 217, and a self-locking spring 218. The self-locking base 215 is fixedly installed on the inner surface of the changing plate 204. The self-locking slide 216 is an L-shaped plate composed of a short plate and a long plate. The two ends of the self-locking spring 214 are fixedly installed on the inner wall of the cavity of the self-locking base 215 and the outer wall of the short plate, respectively. The short plate is movably assembled inside the self-locking base 215. The outer surface of the long plate has a semi-circular protrusion integrally formed. The outer surface of the self-locking base 215 has a limiting protrusion corresponding to the semi-circular protrusion integrally formed. The self-locking spring 218 is fixedly installed on the inner surface of the long plate, and the self-locking clamping plate 217 is fixedly installed on the outer end of the self-locking spring 218.

[0062] In the initial state, under the action of the self-locking spring 214, the self-locking slide 216 is located inside and outside the self-locking base 215, and the self-locking clamping plate 217 is in contact with the drill bit 4. At this time, the self-locking spring 218 is in a compressed state, and the drill bit 4 is fixed by the elastic force.

[0063] The inner surface of the self-locking clamping plate 217 has two curved ends, which makes it easier to move the self-locking clamping plate 217 onto the drill bit 4 or into the self-locking base 215.

[0064] The second self-locking component includes a replacement spring 212 and a replacement crossbar 213. The replacement spring 212 is fixedly installed on the upper outer surface of the replacement vertical plate 205. The outer end of the replacement crossbar 213 is integrally formed with a rectangular plate, and the rectangular plate is fixedly installed on the outer end of the replacement spring 212. The inner end of the crossbar 213 passes through the replacement spring 212 and the replacement vertical plate 205. The replacement crossbar 213, the semi-circular protrusion, and the limiting protrusion are located on the same vertical plane.

[0065] In the initial state, the inner end of the replacement crossbar 213 is within the rotation trajectory of the semi-circular protrusion.

[0066] The inner end of the replacement crossbar 213 is arc-shaped. When the replacement disc 204 rotates, the semi-circular protrusion of the self-locking slide 216 will contact the inner end of the replacement crossbar 213. Under the restriction of the replacement crossbar 213, the self-locking slide 216 will move into the self-locking base 215. When all the structures on the self-locking slide 216 no longer restrict the drill bit 4, the replacement motor 201 will be controlled to stop working. At this time, the drill bit placement slot corresponding to the drill bit 4 is in a horizontal state, and then docking work can be carried out.

[0067] As the replacement disc 204 continues to rotate, the semi-circular protrusion will exert pressure on the replacement crossbar 213, causing it to stretch the replacement spring 212, which will allow the self-locking component one to pass through the self-locking component two, allowing the replacement disc 204 to continue rotating.

[0068] The inner end of the replacement crossbar 213 is in contact with the semi-circular convex arc surface to ensure that the lateral movement of the replacement crossbar 213 is carried out smoothly.

[0069] Specifically, such as Figure 5As shown, the positioning assembly includes a rack 206, a clamping cylinder 207, a positioning slide rail 208, a positioning gear 209, a rack 210, a clamping cylinder 211, and a positioning motor 219. The positioning slide rail 208 is fixedly installed on the outer surface of the replacement plate 205 and is located outside the replacement disc 204. The positioning motor 219 is fixedly installed on the lower surface of the positioning slide rail 208. The positioning gear 209 is fixedly installed at the output end of the positioning motor 219 and is located on the upper side of the positioning slide rail 208. The positioning slide rail 208... The internal part of the 8 is equipped with a guide rail. The clamping cylinder 1 207 and the clamping cylinder 211 are symmetrically mounted on the guide rail. The lower side walls of the clamping cylinder 1 207 and the clamping cylinder 211 are respectively fixedly installed with rack 1 206 and rack 210 that mesh with the positioning gear 209. The rack 1 206 and rack 210 are located on both sides of the positioning gear 209. The upper end of the clamping cylinder 1 207 and the clamping cylinder 211 is a symmetrical semi-cylindrical structure. The outer end of the semi-cylindrical structure is integrally formed with a baffle. The inner side of the baffle is provided with an arc groove.

[0070] Starting the positioning motor 219 will drive the positioning gear 209 to rotate, which in turn will drive rack 1 206 and rack 210 to move in opposite directions at the same time, causing clamping cylinder 1 207 and clamping cylinder 211 to move in opposite directions at the same time.

[0071] After the self-locking assembly restricts the pair of drill bits 4, the positioning motor 219 is activated to move the clamping cylinder 207 and the clamping cylinder 211 inward to clamp and fix the drill bits 4. Then the docking work between the drill bits 4 and the tunneling pipe 5 can be carried out.

[0072] Clamping cylinder 1 207 and clamping cylinder 2 211 can clamp and fix the drill bit 4 through the semi-cylindrical structure. At this time, the baffle plays the role of restricting the position of the drill bit 4. In addition, the drill bit 4 can also be clamped and fixed through the arc groove on the baffle.

[0073] When performing the splicing of tunneling pipe 5, the tunneling pipe 5 on the front side can be clamped and fixed through the arc groove on the baffle.

[0074] Rubber pads can be installed in the arc-shaped grooves on the baffle to prevent damage to the drill bit 4 and the tunneling pipe 5, and to increase the clamping effect.

[0075] Specifically, such as Figure 8 As shown, the movable assembly includes a connecting base 301, a connecting hydraulic cylinder 302, and a connecting slide 303. The connecting base 301 is fixedly installed on the rear surface of the bracket 101. The connecting base 301 has a box structure. The connecting hydraulic cylinder 302 is fixedly installed on the front surface of the inner cavity of the connecting base 301. The connecting slide 303 consists of a lower movable plate and an upper support frame. The movable plate is fixedly installed on the output end of the connecting hydraulic cylinder 302, and the movable plate is movably assembled inside the connecting base 301.

[0076] The position of the continuing slide 303 within the continuing base 301 is moved by the operation of the continuing hydraulic cylinder 302. The position of the tunneling pipe 5 on the continuing drum 305 is adjusted by the movement, so that the tunneling pipe 5 can be coaxial with the docking turntable 106.

[0077] Specifically, such as Figure 1 and Figure 8 As shown, the power assembly includes a connecting belt assembly 304 and a connecting motor 311. The connecting motor 311 is fixedly installed on the inner surface of the support frame, and the connecting belt assembly 304 is assembled on the outer surface of the support frame. The connecting belt assembly 304 consists of a connecting pulley and a connecting belt. The connecting pulley is fixedly installed at the output end of the connecting motor 311. Circular holes are provided on both the left and right surfaces of the support frame, and a connecting drum 305 is rotatably assembled in the circular hole. The outer end of the connecting drum 305 is connected to the connecting pulley through the connecting belt.

[0078] After the connecting motor 311 is started, the connecting drum 305 will be driven to rotate through the connecting belt group 304, which can then rotate the tunneling pipe 5 to the corresponding position, and then it can be moved by the moving component.

[0079] The middle part of the connecting drum 305 is a through hole, and the replacement connecting rod 203 passes through the connecting drum 305. The replacement disc 204 is located on the outside of one end of the connecting drum 305, so that the rotation of the replacement connecting rod 203 and the replacement disc 204 does not affect the rotation of the connecting drum 305.

[0080] The through-hole diameter of the connecting drum 305 is relatively large, so that the connecting drum 305 will not come into contact with the replacement connecting rod 203 during the movement.

[0081] Specifically, such as Figure 9 As shown, the clamping assembly includes a clamping mounting block 307, a clamping spring 308, a clamping pressure rod 309, and a clamping upright plate 310. The clamping pressure rod 309 consists of a cylindrical block and a pressure rod. Two cylindrical blocks are fixedly installed at both ends of the pressure rod, and the cylindrical blocks are fixedly installed on the side wall of the clamping seat 306. The clamping upright plate 310 is fixedly installed on the outer surface of the connecting drum 305. A connecting post that penetrates the clamping upright plate 310 is fixedly installed in the middle of the outer surface of the pressure rod. The clamping mounting block 307 is fixedly installed at the outer end of the connecting post. The clamping spring 308 is fixedly installed between the clamping mounting block 307 and the clamping upright plate 310. A first inclined surface is formed on the upper surface of the clamping mounting block 307.

[0082] The upper end of the mating rod 104 is bent vertically inward, and the inner end of the mating rod 104 is provided with a second inclined surface that matches the first inclined surface.

[0083] When the moving component moves the connecting slide 303 forward, the second inclined surface on the mating rod 104 contacts the first inclined surface on the clamping mounting block 307, and applies a downward force to the clamping mounting block 307, causing it to drive the clamping pressure rod 309 to press against the mounting base 306, thereby achieving the clamping and fixing of the tunneling pipe 5, which facilitates its connection with the docking turntable 106.

[0084] When the connecting slide 303 moves back to its original position, the clamping spring 308 will cause the clamping mounting block 307 to reset.

[0085] Specifically, a cylindrical cavity is provided inside the cylindrical block, and a clamping spring is fixedly installed inside the cylindrical cavity. The outer end of the clamping spring is fixedly installed on the side wall of the card seat 306, and the clamping spring is always in a compressed state.

[0086] Under the action of the clamping spring, the clamping rod 309 will always exert pressure on the clamping seat 306, which will cause the side wall of the clamping seat 306 to bend inward, thereby limiting the tunneling pipe 5 and preventing the tunneling pipe 5 from falling out of the clamping seat 306 during the rotation of the connecting drum 305.

[0087] Example 2

[0088] Connection between drill bit 4 and tunneling pipe 5:

[0089] a. Start the continuing motor 311 to drive the continuing drum 305 to rotate, rotate the tunneling pipe 5 to be installed to the set position, and then start the continuing hydraulic cylinder 302 to drive the continuing drum 305 to move until the mating rod 104 contacts the clamping installation block 307 and presses the tunneling pipe 5 into place.

[0090] b. Start the docking motor 107 to drive the docking turntable 106 to rotate. At the same time, under the action of the lead screw 103, the docking turntable 106 moves forward to complete the screw connection between the docking drum 106 and the tunneling pipe 5. Then, run the extension hydraulic cylinder 302 to drive the extension drum 305 to reset.

[0091] c. Start the replacement motor 201 to drive the replacement disc 204 to rotate, and rotate the drill bit 4 that needs to be installed or replaced to the position slide rail 208.

[0092] During this process, the replacement of the crossbar 213 and the self-locking slide 216 will cause the self-locking component to no longer limit and fix the position of the drill bit 4;

[0093] d. Start the positioning motor 219 to drive the positioning gear 209 to rotate, which will cause the clamping cylinder 1 207 and the clamping cylinder 211 to move inward and clamp the drill bit 4 in place;

[0094] e. Start the docking motor 107 to make the docking turntable 106 and the tunneling pipe 5 rotate and move simultaneously, so as to complete the threaded connection between the tunneling pipe 5 and the drill bit 4, that is, to complete the docking work between the tunneling pipe 5 and the drill bit 4.

[0095] Example 3

[0096] Replacement of drill bit 4:

[0097] a. Move the drill bit 4 above the positioning slide rail 208, start the positioning motor 219, and cause the clamping cylinder 1 207 and clamping cylinder 211 to move inward and clamp the drill bit 4 in place.

[0098] b. Start the docking motor 107 to rotate in the opposite direction, which will drive the docking turntable 106 and the tunneling pipe 5 to rotate and move in the opposite direction, so that the docking turntable 106, the tunneling pipe 5 and the drill bit 4 are separated, and the drill bit 4 is retrieved.

[0099] After drill bit 4 is retracted, it is retrieved manually.

[0100] c. Repeat steps c, d, and e in Example 2 to complete the docking of the tunneling pipe 5 with the new drill bit 4, that is, to complete the replacement of the drill bit 4.

[0101] Example 4

[0102] Continuation of tunneling pipe 5:

[0103] a. Move the tunneling pipe 5 in use above the positioning slide rail 208, start the positioning motor 219, and make the clamping cylinder 1 207 and clamping cylinder 211 move inward and clamp the tunneling pipe 5 in place;

[0104] b. Start the docking motor 107 to rotate in the opposite direction, which will drive the docking turntable 106 to rotate in the opposite direction and move in the opposite direction, so that the docking turntable 106 is in contact with the tunneling pipe 5, and move the docking turntable 106 to the initial position.

[0105] c. Start the continuing motor 311 to drive the continuing drum 305 to rotate, rotate the next tunneling pipe 5 to the preset position, and drive the continuing drum 305 to move through the continuing hydraulic cylinder 302, so that the next tunneling pipe 5 moves to the position corresponding to the docking turntable 106 and is pressed and fixed by the clamping component.

[0106] d. Start the docking motor 107 to drive the docking turntable 106 to rotate and move, so that the docking turntable 106 is connected to the next tunneling pipe 5, and then the connecting drum 305 is reset.

[0107] e. Continue to start the docking motor 107, drive the docking turntable 106 and the next tunneling pipe 5 to rotate and move, so that the next tunneling pipe 5 is connected to the tunneling pipe 5, thus completing the continuation of the tunneling pipe 5.

As long as these changes do not depart from the concept of the present invention, they all fall within the protection scope of the present invention.
