Description

Technical Field

[0001] The invention relates to the technical field of metal casing processing and grinding, in particular to a casing processing and grinding device for mineral resource exploration. Background Art

[0002] Mineral resource exploration casing (hereinafter referred to as casing) is a key equipment used in geological drilling, mainly used to protect the borehole structure, isolate complex formations and maintain wellbore stability. Since there will be burrs, cracks and other defects on the surface of the pipe during the casing production process, these defects will increase the friction resistance during the drilling process and increase the risk of wear of the casing and drilling tools. Therefore, grinding the casing is a basic technical link to improve the efficiency of mineral resource exploration and the level of safe production.

[0003] In the actual production and processing process, the sleeve is usually ground by a friction roller to drive the sleeve to rotate, and a guide wheel is used to allow the sleeve to be continuously fed during the rotation process, so that the sleeve is spirally ground progressively with the cooperation of the grinding wheel, thereby ensuring the grinding effect of the sleeve.

[0004] Although the above-mentioned grinding equipment and grinding method can quickly complete the grinding of the casing, the side of the casing is very likely to be uneven during the above-mentioned grinding process. This unevenness is likely to cause the drill tool installed with the casing to cause equipment instability during the drilling process during the subsequent use of the casing; in addition, since the above-mentioned grinding equipment uses a single grinding wheel to grind the casing, it is easy to have incomplete grinding, which affects the subsequent use of the polished casing.

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0034] See also Figure 1-Figure 2 A mineral resource exploration casing processing and grinding device includes a grinding workbench 1, a conveying platform 11 is installed on the rear side of the grinding workbench 1, a right-angle mounting frame 12 is installed on the left side of the grinding workbench 1, an inclined baffle 13 is fixed on the top of the grinding workbench 1, a horizontal conveying unit 2 is installed between the top of the conveying platform 11 and the grinding workbench 1, a vertical grinding unit 3 is installed between the right-angle mounting frame 12 and the grinding workbench 1, and a follow-up grinding unit 4 is connected to the vertical grinding unit 3.

[0035] The present invention first grinds the sleeve transmitted by the horizontal transmission unit 2 through the vertical grinding unit 3. After the vertical grinding unit 3 completes the grinding of the sleeve, the follow-up grinding unit 4 completes the auxiliary grinding of the sleeve as the vertical grinding unit 3 continues to grind, thereby improving the comprehensiveness of the grinding of the sleeve and ensuring the effect and uniformity of the grinding of the sleeve.

[0036] Specifically, the operator first places the sleeve to be polished on the horizontal conveying unit 2, and then controls the horizontal conveying unit 2 to drive the sleeve to move from back to front. In the process of the sleeve moving from back to front, the vertical polishing unit 3 will first polish the sleeve in the conveying process. After the vertical polishing unit 3 completes the polishing of the sleeve, the sleeve will move to the position of the follow-up polishing unit 4, and then the follow-up polishing unit 4 will polish the sleeve, thereby ensuring that the sleeve is fully and effectively polished. As the follow-up polishing unit 4 completes the polishing of the sleeve, the horizontal conveying unit 2 will convey the sleeve to the subsequent processing position.

[0037] See also Figure 1-Figure 3 The horizontal transmission unit 2 includes a driving shaft 21 rotatably mounted on the top of the grinding workbench 1, and a plurality of friction transmission rollers 211 are evenly fixed on the driving shaft 21. A front extension plate 212 is fixed at the front end of the grinding workbench 1, and a transmission power motor 213 is installed on the top of the front extension plate 212 through a motor box. The output end of the transmission power motor 213 is fixedly connected to the driving shaft 21, and a driven shaft 22 is rotatably mounted on the top of the transmission platform 11 at a position corresponding to the driving shaft 21. The driven shaft 22 is connected to the driving shaft 21 through a coupling, and a plurality of friction transmission rollers 211 are also evenly fixed on the driven shaft 22, and the intervals between the friction transmission rollers 211 on the driven shaft 22 are greater than the intervals between the friction transmission rollers 211 on the driving shaft 21.

[0038] A horizontal adjustment element 23 is commonly provided on the grinding workbench 1 and the conveying platform 11, and a plurality of tapered guide rollers 24 are evenly installed on the horizontal adjustment element 23; the horizontal adjustment element 23 includes a plurality of mounting plates 231 fixed on the top of the conveying platform 11 and the grinding workbench 1, and an adjusting stud 232 is threadedly connected to the mounting plate 231 in the middle position, an adjusting turntable 233 is fixed to the left end of the adjusting stud 232, and a horizontal plate 234 is fixed to the right end of the adjusting stud 232, the horizontal plate 234 is slidably connected to the front and rear mounting plates 231 through a round rod, and the two horizontal plates 234 are rotationally connected to the corresponding tapered guide rollers 24 through a connecting plate 235.

[0039] The horizontal conveying unit 2 is used to convey the sleeve, so as to ensure that the sleeve moves steadily from the position where the operator places it to the position of the vertical grinding unit 3 and the follow-up grinding unit 4, thereby ensuring that the vertical grinding unit 3 and the follow-up grinding unit 4 quickly grind the sleeve. At the same time, the horizontal adjustment element 23 and the tapered guide roller 24 cooperate to guide the sleeve, which can provide continuous and stable guidance for the movement of the sleeve.

[0040] First, the operator adjusts the position of the tapered guide roller 24 according to the grinding accuracy and size of the sleeve to be ground. Specifically, the operator first rotates the adjustment dial 233 and drives the adjustment stud 232 to rotate, so that the adjustment stud 232 drives the horizontal plate 234 to move left and right as a whole, thereby ensuring that the position of all tapered guide rollers 24 is changed. After the position adjustment of the tapered guide roller 24 is completed, the operator places the sleeve to be ground between the tapered guide roller 24 and the friction transmission roller 211, and the friction transmission roller 212 is driven by the friction transmission roller 213 to rotate. 11 and the tapered guide roller 24 support the sleeve, and then control the transmission power motor 213 to drive the driving shaft 21 and the driven shaft 22 to rotate synchronously. When the driving shaft 21 and the driven shaft 22 rotate, the friction transmission roller 211 will rotate counterclockwise, and the sleeve that is continuously rubbed with the friction transmission roller 211 will be subjected to the friction force of the friction transmission roller 211 and rotate clockwise. As the sleeve rotates, the tapered guide roller 24 will rotate counterclockwise due to the friction force generated by the sleeve and the tapered guide roller 24 itself and drive the sleeve to move forward.

[0041] See also Figure 1 , Figure 3 , Figure 4 and Figure 5The vertical grinding unit 3 includes a pad 31 fixed on the top of the grinding workbench 1 and the right-angle mounting frame 12, and an active grinding element 32 for grinding the sleeve transmitted by the horizontal transmission unit 2 is arranged on the top of the pad 31; the active grinding element 32 includes an oblique mounting sleeve 321 fixed on the top of the pad 31, and a grinding wheel 322 is rotatably installed on one end of the oblique mounting sleeve 321 close to the friction transmission roller 211, and a grinding power motor 323 is installed on the top of the pad 31 through a motor seat, and a transmission belt 324 is connected between the output end of the grinding power motor 323 and the transmission shaft of the grinding wheel 322, and the transmission belt 324 is accommodated in the oblique mounting sleeve 321.

[0042] An elastic telescopic rod is fixedly installed on the side of the inclined baffle 13 close to the active grinding element 32 through a square connecting column, and an arc-shaped limit plate 131 is fixed to the telescopic end of the elastic telescopic rod. A plurality of balls are evenly arranged on the inner arc surface of the arc-shaped limit plate 131, and an arc-shaped guide plate 132 is fixed to the rear side of the arc-shaped limit plate 131.

[0043] The vertical grinding unit 3 is used to continuously grind the side surface of the sleeve transmitted to the position of the vertical grinding unit 3, and through the limiting effect of the arc guide plate 132 and the ball and arc limit plate 131, it is ensured that the sleeve is stably and continuously polished by the grinding wheel 322 while being transmitted by the horizontal transmission unit 2, thereby avoiding displacement and deflection of the sleeve during the grinding process by the grinding wheel 322.

[0044] Specifically, before the sleeve is transmitted to the position of the vertical grinding unit 3 by the cooperation of the friction transmission roller 211 and the tapered guide roller 24, the sleeve will first contact the arc guide plate 132 and push the arc limit plate 131 to the right along the guide surface of the arc guide plate 132. After the pushing is completed, the sleeve will continue to contact with the ball, and then the grinding power motor 323 will be controlled to continuously drive the transmission shaft of the grinding wheel 322 to rotate through the transmission belt 324, thereby driving the grinding wheel 322 to rotate counterclockwise. Due to the speed difference between the grinding wheel 322 and the sleeve, the grinding wheel 322 will continue to grind the sleeve. When the grinding wheel 322 contacts the sleeve and grinds it, the sleeve will be subjected to the driving force generated by the grinding wheel 322 when the sleeve is driven to rotate. At the same time, the elastic force generated when the elastic telescopic rod is compressed will offset the driving force of the grinding wheel 322 on the sleeve, thereby ensuring that the grinding wheel 322 stably grinds the sleeve.

[0045] See also Figure 1 , Figure 3 , Figure 5 and Figure 7The follow-up grinding unit 4 includes a right-angle positioning column 41 fixed on the top of the pad 31 and located in front of the active grinding element 32, a sliding limit column 411 is fixed to the rear side of the horizontal section of the right-angle positioning column 41, a sliding assembly sleeve 412 is sleeved on the sliding limit column 411, a horizontal spring is connected between the sliding assembly sleeve 412 and the right-angle positioning column 41, a cam pushing element 42 for pushing the sliding assembly sleeve 412 is connected between the sliding assembly sleeve 412 and the active grinding element 32, and a follow-up grinding element 43 is fixed to the side of the sliding assembly sleeve 412 close to the driven shaft 22.

[0046] The cam push element 42 includes a driven turntable 421 fixed to the side of the transmission shaft of the grinding wheel 322 , a plurality of wedge-shaped protrusions 422 are evenly fixed on the front side of the driven turntable 421 , and a crank transmission rod 423 is fixed to the side of the sliding assembly sleeve 412 .

[0047] The follow-up grinding element 43 can be used to perform subsequent grinding on the sleeve after being ground by the grinding wheel 322, thereby improving the grinding accuracy of the sleeve and the dimensional accuracy of the sleeve after grinding, and the crank transmission rod 423 can be pushed by the wedge-shaped protrusion block 422 to drive the sliding collection sleeve 412 to move, thereby driving the follow-up grinding element 43 to reciprocate along the moving direction of the sleeve through the sliding collection sleeve 412, further improving the grinding effect of the follow-up grinding element 43.

[0048] Specifically, when the sleeve is transmitted to the position of the follower grinding unit 4 under the cooperation of the friction transmission roller 211 and the tapered guide roller 24, the follower grinding element 43 will contact the sleeve and grind the sleeve at the same time, and as the grinding wheel 322 grinds the sleeve, the grinding wheel 322 will continue to drive the driven rotating disk 421 to rotate. When the driven rotating disk 421 rotates, the wedge-shaped protrusion block 422 will push the crank transmission rod 423, so that the crank transmission rod 423 drives the sliding set The assembly sleeve 412 moves as a whole toward the right-angle positioning column 41, and the sliding assembly sleeve 412 will compress the horizontal spring, and then the sliding assembly sleeve 412 will drive the follow-up grinding element 43 to move forward. At this time, the follow-up grinding element 43 moves forward and grinds the sleeve. When the crank transmission rod 423 separates from the wedge-shaped protrusion block 422, the sliding assembly sleeve 412 will return to its original position under the elastic force of the horizontal spring, and at the same time drive the follow-up grinding element 43 to move again and grind the sleeve.

[0049] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.12The follower grinding element 43 includes a plurality of inclined connecting columns 431 evenly fixed on the side of the sliding assembly sleeve 412 from front to back, and a lower arc plate 432, a middle arc plate 433 and an upper arc plate 434 are fixed in sequence on the end of the inclined connecting column 431 away from the sliding assembly sleeve 412 from front to back, and a circumferential grinding structure is arranged on the lower arc plate 432 and the middle arc plate 433, and a pre-grinding structure is arranged on the upper arc plate 434.

[0050] The circumferential grinding structure includes an avoidance groove opened on the inner arc surface of the lower arc plate 432 and the middle arc plate 433, and the circumferential grinding blocks 435 are symmetrically limited and slidably connected in the avoidance groove, and V-shaped spring sheets are connected between the two circumferential grinding blocks 435 and the avoidance groove. The lower arc plate 432 and the middle arc plate 433 are both provided with a through groove 436, and a bevel matching block 437 is slidably connected in the through groove 436. A pushing member corresponding to the bevel matching block 437 is fixed on the right side surface of the right-angle positioning column 41; the pushing member includes a fixed column 438 fixed at the right end of the horizontal section of the right-angle positioning column 41, and a pushing block 439 is fixed to the rear side of the fixed column 438 at the position corresponding to each bevel matching block 437.

[0051] The follower grinding element 43 can continuously grind the sleeve under the reciprocating push of the cam pushing element 42, and through the pre-grinding structure, the unevenly ground position of the grinding wheel 322 can be targetedly ground first, thereby ensuring that the surface of the sleeve is evenly ground. At the same time, the circumferential grinding structure can continuously perform circumferential reciprocating grinding on the side of the sleeve, thereby ensuring the grinding effect of the sleeve, thereby improving the grinding effect of the sleeve.

[0052] Specifically, when the sliding assembly sleeve 412 and the crank drive rod 423 are pushed forward by the wedge-shaped protrusion block 422, the lower arc plate 432, the middle arc plate 433 and the upper arc plate 434 will drive the circumferential grinding structure and the pre-grinding structure to move forward together. When the circumferential grinding structure moves forward, the circumferential grinding block 435 performs spiral progressive grinding on the sleeve, and because the friction drive roller 211 continuously drives the sleeve to rotate, the circumferential grinding block 435 can fully grind the sleeve. When the circumferential grinding block 435 moves forward, the pushing block 439 pushes the bevel matching block 437, and the bevel matching block 437 will drive the two circumferential grinding blocks 435 at the same time, so that the two circumferential grinding blocks 435 compress the V-shaped spring sheet, and then the circumferential grinding blocks 435 move away from each other along the side of the sleeve and grind at the same time. The circumferential grinding method of multiple circumferential grinding blocks 435 not only makes the grinding range wider and improves the uniformity of grinding, but also improves the efficiency of grinding.

[0053] When the bevel mating block 437 and the pushing block 439 move away from each other, the bevel mating block 437 will release the pushing effect on the circumferential grinding block 435, and the circumferential grinding block 435 will return to its original position due to the elastic force of the V-shaped spring sheet and push the bevel mating block 437. At this time, the circumferential grinding block 435 will grind the side of the sleeve in a circumferential movement again.

[0054] See also Figure 7 and Fig.10 The pre-grinding structure includes a fixed grinding block 440 fixed on the inner arc surface of the upper arc plate 434, a track guide groove 441 is opened on the inner arc surface of the upper arc plate 434 and located on the rear side of the fixed grinding block 440, a guide rail is arranged in the track guide groove 441, a mobile grinding block 442 is slidably connected in the guide rail, a slider guide plate 443 is connected to the top of the track guide groove 441 through a V-shaped spring sheet, and the slider guide plate 443 is against the side wall of the mobile grinding block 442.

[0055] In this embodiment, if Fig.10 and Fig.11 As shown, the guide rail is composed of an arc section located at the bottom and a straight section located at the top. The straight section located at the top is tangent to the arc section, and square interlocking blocks are fixed at the positions of the guide rails on the front and rear sides of the movable grinding block 442, and the square interlocking blocks are slidably connected to the guide rails.

[0056] The pre-grinding structure can pre-grind the uneven positions on the side of the sleeve in a targeted manner during the process of the sleeve rotating and moving forward, thereby ensuring the uniformity of the grinding of the side of the sleeve, and the movable grinding block 442 can comprehensively grind the positions that the grinding wheel 322 cannot grind in place. At the same time, the sleeve is ground by combining the movable grinding block 442 and the fixed grinding block 440 in a dynamic and static manner, which can significantly improve the grinding effect of the side of the sleeve.

[0057] Specifically, when the sleeve is transmitted to the position of the follow-up grinding unit 4 under the cooperation of the friction transmission roller 211 and the tapered guide roller 24, the sleeve first contacts the movable grinding block 442. Since the sleeve is in a clockwise rotation state, when the movable grinding block 442 contacts the raised position of the sleeve, the movable grinding block 442 will be moved upward by the friction of the raised position of the sleeve, and the movable grinding block 442 will first move in an arc along the guide rail until the movable grinding block 442 moves to the straight section of the guide rail. At this time, the movable grinding block 442 will be pushed by the raised position on the sleeve. It slides along the straight section of the guide rail, thereby gradually moving away from the raised part on the sleeve, and then performs targeted grinding on the raised position on the sleeve, and avoids the raised height on the side of the sleeve being too large to interfere with the fixed grinding block 440 and affect the subsequent transmission of the sleeve. When the protrusion on the sleeve is separated from the movable grinding block 442, the movable grinding block 442 will return to its initial position under the pressure of the slider guide plate 443 driven by the elastic force of the V-shaped spring sheet. At the same time, the fixed grinding block 440 will continue to perform spiral progressive grinding on the side of the sleeve, and further grind the raised part on the side of the sleeve.

[0058] See also Figure 1-Figure 12 The working steps of the present invention are as follows: In the first step, the operator rotates the adjustment dial 233 according to the size of the sleeve and the requirements of the grinding accuracy. As the adjustment dial 233 rotates, it will drive the horizontal plate 234 to move horizontally through the adjustment stud 232, thereby realizing the synchronous position calibration of all the tapered guide rollers 24. After the position adjustment of the tapered guide roller 24 is completed, the sleeve is stably placed on the support structure composed of the tapered guide roller 24 and the friction transmission roller 211.

[0059] In the second step, after the sleeve is stably placed on the tapered guide roller 24 and the friction transmission roller 211, the transmission power motor 213 is started to drive the driving shaft 21 to rotate counterclockwise, and the driven shaft 22 is driven to rotate counterclockwise synchronously through the coupling. As the driven shaft 22 and the driving shaft 21 rotate, the friction transmission roller 211 will drive the sleeve to rotate clockwise through friction force, and cooperate with the guide surface of the tapered guide roller 24 to realize axial feeding.

[0060] In the third step, as the sleeve moves from back to front, the grinding power motor 323 is controlled to continuously drive the grinding wheel 322 to rotate at high speed through the transmission belt 324. As the grinding wheel 322 continues to rotate, the grinding wheel 322 will continuously grind the side of the sleeve transmitted to the position of the grinding wheel 322. In the process of the grinding wheel 322 grinding the side of the sleeve, the arc-shaped limit plate 131 supported by the elastic telescopic rod will contact the sleeve through the ball bearing, and use the elastic deformation to offset the reaction force generated by grinding, thereby ensuring that the sleeve is stably ground.

[0061] In the fourth step, when the grinding wheel 322 finishes grinding the sleeve, the transmission shaft of the grinding wheel 322 will drive the driven turntable 421 to rotate, and the multiple wedge-shaped protrusions 422 will periodically push the crank transmission rod 423, so that the sliding assembly sleeve 412 reciprocates back and forth under the combined action of the horizontal spring force and the push of the wedge-shaped protrusions 422. As the sliding assembly sleeve 412 reciprocates back and forth, the sliding assembly sleeve 412 will drive the follow-up grinding element 43 to feed and reset in a cyclic motion along the axis of the sleeve and continuously grind the sleeve.

[0062] In the fifth step, during the reciprocating movement of the sliding assembly sleeve 412, the circumferential grinding block 435 will reciprocate along the circumference of the sleeve under the action of the inclined surface of the pushing block 439, thereby cooperating with the continuous rotation of the sleeve to achieve spiral progressive grinding, and the mobile grinding block 442 follows the surface of the sleeve through the guide rail to perform targeted grinding on the raised position. At the same time, after the mobile grinding block 442 is separated from the raised position of the sleeve, the V-shaped spring sheet will push the mobile grinding block 442 to return to its original position. When the follow-up grinding unit 4 and the vertical grinding unit 3 complete the grinding of the sleeve during the transmission process, the horizontal transmission unit 2 will transmit the sleeve to the subsequent processing position.
