Description

Technical Field

[0001] This invention relates to the field of coal mining equipment technology, specifically to an electric flange welding precision positioning device for coal washing equipment. Background Technology

[0002] Coal washing equipment is a type of mechanical equipment used in the coal washing process. It comes in various types and functions, and the main types include drum coal washing machines, spiral coal washing machines, jig coal washing machines, and flotation coal washing machines.

[0003] When installing equipment pipelines on coal washing equipment, flange connections are generally used. Therefore, flanges need to be welded to the ends of the equipment pipelines. When connecting two pipelines with flanges, the flanges on both sides need to be precisely aligned. Therefore, during the process of welding flanges to the ends of the equipment pipelines, the pipelines need to be precisely aligned with the flanges.

[0004] Shorter pipelines are easier to install and connect vertically, and can be rotated to allow for 360-degree welding at the connection between the pipeline and the flange. However, longer pipelines require the use of hoisting equipment. This is cumbersome as it involves repeated installation and disassembly of the hoisting equipment. Furthermore, the pipeline is prone to movement during hoisting, causing the central axis of the pipeline and flange to misalign and potentially resulting in misalignment at the connection. Additionally, it is inconvenient to rotate the hoisted pipeline, requiring welding equipment to be used for welding around the pipeline, which is also cumbersome. Therefore, this application proposes an electric flange welding precision positioning device for coal washing equipment. Summary of the Invention

[0033] This invention discloses an electric flange welding precision positioning device for coal washing equipment, which has the following beneficial effects:

[0034] This coal washing equipment uses an electric flange welding precision positioning device. When the equipment pipeline positioning unit positions the main body of the equipment pipeline, and the flange positioning unit positions the main body of the flange, the center lines of the main body of the equipment pipeline and the main body of the flange are aligned. At this time, the drive unit drives the flange positioning unit and the main body of the flange to move until the end of the main body of the flange contacts the end of the main body of the equipment pipeline, thereby achieving precise docking and positioning. The positioning rotation unit is activated to drive the main body of the equipment pipeline to rotate relative to the equipment pipeline positioning unit, and the flange to rotate relative to the flange positioning unit, thereby facilitating 360-degree welding around the connection between the flange and the main body of the equipment pipeline. After welding, the flange and the main body of the equipment pipeline are removed.

[0035] The coal washing equipment uses an electric flange welding precision positioning device. Since the flange positioning unit, equipment pipeline positioning unit and positioning rotation unit are all equipped with drive units at the bottom, when the second drive motor is working, its output end can drive the rotating rod to rotate, which in turn can drive the driven gear to rotate through the drive gear. The driven gear and the transmission rack mesh and connect, which can make the drive box move accordingly, and make the rollers on both sides of the drive box roll on the inner wall of the sliding groove.

[0036] This coal washing equipment uses an electric flange welding precision positioning device. When the first drive motor is working, its output end drives the spline shaft to rotate, which in turn causes the third bevel gear to rotate. Because the second and third bevel gears mesh, the transmission shaft rotates accordingly. This, in turn, drives the rotating shaft inside the positioning rubber wheel to rotate through the first bevel gear at the top of the transmission shaft, thus driving the positioning rubber wheel to rotate. Simultaneously, during the lateral movement of the moving seat, the second transmission box can be moved along with it, and the first transmission box can be moved through the connecting block. The transmission shaft between the first and second transmission boxes can also move accordingly. When the first transmission box moves, it can drive the third bevel gear to move relative to the spline shaft, so that the lateral movement of the moving seat does not affect the first drive motor's operation in conjunction with the spline shaft to drive the transmission shaft and positioning rubber wheel to rotate.

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0048] This application provides an electric flange welding precision positioning device for coal washing equipment. It solves the problem that if the pipeline is long, hoisting equipment is required, which is cumbersome due to repeated installation and disassembly using lifting tools. Furthermore, the pipeline is prone to movement during hoisting, causing the pipeline and flange's central axis to misalign, potentially leading to misalignment at the connection. Additionally, the hoisted pipeline is difficult to rotate, necessitating welding equipment to weld around it, which is also cumbersome. After the equipment pipeline positioning unit 3 positions the equipment pipeline body 5, the flange body 6 is placed on the side of the flange positioning unit 2, and the flange positioning unit 2 positions the flange body 6. Because the centerlines of the flange positioning unit 2 and the equipment pipeline positioning unit 3 overlap, the centerlines of the equipment pipeline body 5 and the flange body 6 are aligned. Then, the drive unit 7 moves the flange positioning unit 2 and the flange body 6 until the flange body 6 contacts the end of the equipment pipeline body 5, achieving precise docking and positioning.

[0049] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0050] This invention discloses an electric flange welding precision positioning device for coal washing equipment.

[0051] According to the appendix Figure 1-8 As shown, it includes a support unit 1, and a flange positioning unit 2, an equipment pipeline positioning unit 3, and a positioning rotation unit 4 are installed on top of the support unit 1.

[0052] The flange positioning unit 2 is rotatably connected to the flange body 6 on its side, the equipment pipeline positioning unit 3 is movably inserted into the equipment pipeline body 5, the positioning rotation unit 4 is located outside the equipment pipeline body 5, and the positioning rotation unit 4 can drive the equipment pipeline body 5 to rotate.

[0053] The bottom of the flange positioning unit 2, the equipment pipeline positioning unit 3, and the positioning rotation unit 4 are all equipped with a drive unit 7, which can drive the flange positioning unit 2, the equipment pipeline positioning unit 3, and the positioning rotation unit 4 to move laterally respectively.

[0054] During use, the main body 5 of the equipment pipeline is first inserted between the two equipment pipeline positioning units 3. At this time, the equipment pipeline positioning unit 3 can be moved by the drive unit 7 to position the main body 5 of different lengths. After the equipment pipeline positioning unit 3 positions the main body 5, the flange body 6 is placed on the side of the flange positioning unit 2 and the flange positioning unit 2 positions the flange body 6. Since the center lines of the flange positioning unit 2 and the equipment pipeline positioning unit 3 overlap, the center lines of the equipment pipeline body 5 and the flange body 6 can be aligned. At this time, the flange positioning unit 2 and the flange body 6 are moved by the drive unit 7 until the flange body 6 contacts the end of the equipment pipeline body 5, thereby achieving precise docking and positioning.

[0055] At this point, welding is performed at the connection between the flange body 6 and the equipment pipeline body 5, so that the flange body 6 and the equipment pipeline body 5 are partially welded. Then, the positioning and rotating unit 4 is activated to drive the equipment pipeline body 5 to rotate relative to the equipment pipeline positioning unit 3, and to make the flange body 6 rotate relative to the flange positioning unit 2, thereby facilitating the 360-degree circumferential welding of the connection between the flange body 6 and the equipment pipeline body 5. After the welding is completed, the flange body 6 and the equipment pipeline body 5 are removed.

[0056] Furthermore, the support unit 1 includes:

[0057] Support base 11, slide rail 12 is installed on the top of support base 11, and slide rail 12 has a sliding groove 13 on the side.

[0058] The transmission rack 14 is embedded above the support base 11.

[0059] Furthermore, the drive unit 7 includes:

[0060] The drive box 71 has a second drive motor 73 fixedly installed inside it. Rollers 72 are rotatably arranged on both sides of the drive box 71 and are rolled on the inner wall of the sliding groove 13.

[0061] The rotating rod 74 has one end fixedly connected to the output end of the second drive motor 73, and the other end of the rotating rod 74 is rotatably mounted on the inner wall of the drive box 71. The outer side of the rotating rod 74 is fixedly sleeved with a drive gear 75, and the bottom of the drive box 71 is rotatably mounted with a driven gear 76, which meshes with the drive gear 75 and the transmission rack 14.

[0062] Since the flange positioning unit 2, the equipment pipeline positioning unit 3 and the positioning rotation unit 4 are all equipped with drive units 7 at their bottoms, when the second drive motor 73 is working, its output end can drive the rotating rod 74 to rotate, which in turn can drive the driven gear 76 to rotate through the drive gear 75. The driven gear 76 and the transmission rack 14 mesh with each other, which can make the drive box 71 move accordingly, and make the rollers 72 on both sides of the drive box 71 roll on the inner wall of the sliding groove 13.

[0063] Specifically disclosed, flange positioning unit 2 includes:

[0064] The first annular positioning seat 21 has a plurality of first positioning strips 22 embedded in its outer ring. A first cylinder 23 is fixedly installed on the outer side of each of the plurality of first positioning strips 22. A first connecting strip 24 is fixedly installed on the output end of the first cylinder 23. The first connecting strip 24 is slidably disposed inside the first positioning strip 22, and the end of the first connecting strip 24 extends toward the inner side of the first annular positioning seat 21.

[0065] Multiple positioning wheels 25 are rotatably mounted on the side of the first connecting strip 24.

[0066] Furthermore, a first groove is provided on the outer side of the first positioning strip 22, and a first slider is slidably connected on the inner wall of the first groove. The two ends of the first slider are respectively fixedly connected to the output end of the first cylinder 23 and the end of the first connecting strip 24.

[0067] During use, the first connecting strip 24 can be driven to slide inside the first positioning strip 22 by the multiple first cylinders 23 on its outer side, thereby enabling the multiple positioning wheels 25 to move outward and inward. When the multiple positioning wheels 25 move outward, the flange body 6 can be placed between the multiple positioning wheels 25. Then, when the multiple positioning wheels 25 move inward, the flange body 6 can be clamped. Since the positioning wheels 25 are rotatably set on the side of the end of the first connecting strip 24, the flange body 6 can rotate relative to the multiple positioning wheels 25 when it rotates.

[0068] Furthermore, the equipment pipeline positioning unit 3 includes:

[0069] The second annular positioning seat 31 has a plurality of second positioning strips 32 embedded in its outer ring. A second cylinder 33 is fixedly installed on the outer side of the second positioning strip 32. A second connecting strip is fixedly installed on the output end of the second cylinder 33. The second connecting strip is slidably disposed inside the second positioning strip 32, and the end of the second connecting strip extends toward the inner side of the second annular positioning seat 31.

[0070] Multiple spherical seats 34 are fixedly connected to the ends of multiple second connecting strips, and ball bearings 35 are installed inside the spherical seats 34.

[0071] Furthermore, a second groove is provided on the outer side of the second positioning strip 32, and a second slider is slidably connected on the inner wall of the second groove. The two ends of the second slider are respectively fixedly connected to the output end of the second cylinder 33 and the end of the second connecting strip.

[0072] During use, the second connecting strip can be driven to slide inside the second positioning strip 32 by the multiple second cylinders 33 on its outer side, thereby enabling the multiple spherical seats 34 to move outward and inward. When the multiple spherical seats 34 move outward, the equipment pipeline body 5 can be inserted between the balls 35 at the ends of the multiple spherical seats 34. Then, when the multiple spherical seats 34 move inward, the balls 35 can clamp the outer side of the equipment pipeline body 5. The balls 35 are located inside the spherical seats 34 and can move. On the one hand, it is convenient to adjust the lateral position of the equipment pipeline positioning unit 3 so as to provide more stable support for the equipment pipeline body 5. On the other hand, when the positioning rotation unit 4 is working, it can drive the equipment pipeline body 5 to rotate relative to the multiple balls 35.

[0073] Specifically disclosed, the positioning and rotating unit 4 includes:

[0074] A fixed base 41 is provided, and a movable base 42 is symmetrically slidably arranged above the fixed base 41. A two-way screw 43 is rotatably arranged inside the fixed base 41. Two nut blocks are symmetrically threaded on the outer side of the two-way screw 43, and the two nut blocks are fixedly connected to the two movable bases 42 respectively. A rotating base 46 is fixedly connected to the top of the movable base 42. A movable groove 47 is opened above the fixed base 41, and the nut blocks are slidably arranged on the inner wall of the movable groove 47.

[0075] The positioning rubber wheel 44 is rotatably mounted inside the rotating seat 46, and the positioning rubber wheel 44 is in the same plane as the axis of the equipment pipeline body 5.

[0076] The drive assembly 45 is mounted on the front of the fixed base 41 and can drive the positioning rubber wheel 44 to rotate.

[0077] When the bidirectional lead screw 43 is rotated, it can drive the two nut blocks to slide on the inner walls of the two moving grooves 47 respectively, thereby causing the moving seat 42 at the top of the nut block to move accordingly. This can adjust the distance between the two positioning rubber wheels 44 until the two positioning rubber wheels 44 can tightly abut against the main body of the equipment pipeline 5. Then, the drive assembly 45 drives the two positioning rubber wheels 44 to rotate, thereby driving the main body of the equipment pipeline 5 to rotate accordingly.

[0078] Specifically disclosed, driver component 45 includes:

[0079] The first drive motor 451 is fixedly installed on the front of the fixed base 41. The first transmission box 452 is slidably arranged on the front of the fixed base 41. The first transmission box 452 is fixedly connected to the movable base 42 by a connecting block 4521. The second transmission box 453 is fixedly installed on the outer side of the rotating base 46.

[0080] Spline shaft 454 is rotatably mounted on the front of fixed seat 41. One end of spline shaft 454 is fixedly connected to the output end of first drive motor 451, and first transmission box 452 is movably sleeved on the outside of spline shaft 454.

[0081] The drive shaft 455 is rotatably disposed between the first transmission box 452 and the second transmission box 453, and both ends of the drive shaft 455 are respectively connected to the positioning rubber wheel 44 and the spline shaft 454.

[0082] Furthermore, a rotating shaft 456 is fixedly inserted inside the positioning rubber wheel 44.

[0083] A second bevel gear 458 is fixedly sleeved at the bottom end of the drive shaft 455, and a third bevel gear 459 is movably sleeved on the outer side of the spline shaft 454. A rotating ring 4591 is fixedly connected to the side of the third bevel gear 459. The rotating ring 4591 is rotatably mounted on the inner wall of the first transmission box 452, and the second bevel gear 458 and the third bevel gear 459 are meshed together.

[0084] When the first drive motor 451 is working, its output end drives the spline shaft 454 to rotate, which in turn causes the third bevel gear 459 to rotate. Since the second bevel gear 458 and the third bevel gear 459 are meshed, the transmission shaft 455 rotates accordingly. Then, the first bevel gear 457 at the top of the transmission shaft 455 drives the rotating shaft 456 inside the positioning rubber wheel 44 to rotate, which in turn drives the positioning rubber wheel 44 to rotate.

[0085] Simultaneously, during the lateral movement of the movable seat 42, the second transmission box 453 can be moved accordingly, and the first transmission box 452 can be moved through the connecting block 4521. The transmission shaft 455 between the first transmission box 452 and the second transmission box 453 can also move accordingly. When the first transmission box 452 moves, it can drive the third bevel gear 459 to move relative to the spline shaft 454, so that the lateral movement of the movable seat 42 will not affect the first drive motor 451 cooperating with the spline shaft 454 to drive the transmission shaft 455 and the positioning rubber wheel 44 to rotate.
