Description

Technical Field

[0001] The present invention belongs to the technical field of grinding, and specifically relates to a grinding device for cylindrical building materials. Background Art

[0002] Cylindrical building materials refer to various materials with a cylindrical shape in the construction field. A cylinder is a geometric body enclosed by two equal-sized and parallel circles and a curved surface connecting the two bases. These materials play different roles in building structures, decorations, etc. Cylindrical building materials include metal, stone, wood, and concrete types.

[0003] A cylindrical building material grinding device refers to equipment or tools specifically used for grinding the surface of cylindrical building materials. Its purpose is to make the surface of the cylindrical building materials reach the expected smoothness, flatness or specific texture effects through operations such as grinding and polishing, so as to meet the requirements of building construction, decoration, etc.

[0004] A patent application with the publication number CN112355732A discloses an injection mold, which can form an overall uniform wrapping on the side arc surface of the rock specimen when the grinding rod rotates and grinds, making the specimen's side surface receive uniform radial force as a whole. The lower clamping column and the upper clamping column can stably clamp the two end faces of the rock specimen synchronously and symmetrically, making the specimen receive uniform axial force. This ensures that the specimen is not easily damaged, improves the success rate of preparation, and is not likely to damage the rock specimen during use. It is practical, efficient and has a high success rate of preparation, and can grind and prepare rock specimens with accurate diameter dimensions and smooth surfaces at one time. This lays a foundation for laboratory rock mechanics tests and is of great significance for preventing and controlling mine disasters.

[0005] Currently, in the prior art, when grinding metal cylindrical building pipes, due to the curved surface shape of the pipes and the rotational movement during the grinding process, dust is more likely to spread into the air. Even with a dust suction system, due to the uncertainty of the direction and speed of the generated dust, some dust may not be removed in time, thus polluting the working environment and posing a hazard to the health of operators.

[0006] Therefore, the present invention provides a grinding device for cylindrical building materials. Summary of the Invention

[0007] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0008] The technical solution adopted by the present invention to solve its technical problems is as follows: A cylindrical building material grinding device described in the present invention includes a support plate. A working box is fixedly installed on the top of the support plate. A grinding assembly is arranged inside the working box, and the grinding assembly is used to grind the welded surface of the pipe. A dust collection assembly is arranged inside the working box, and the dust collection assembly is arranged on one side of the grinding assembly. The dust collection assembly includes an air outlet groove plate, and the dust collection assembly is used to centrally collect the dust ground by the grinding assembly through the air outlet groove plate. A pipe moving assembly is arranged on one side of the top of the support plate, and the pipe moving assembly is used to drive the pipe to align with the grinding assembly. A pipe fixing assembly is arranged outside the pipe moving assembly, and the pipe fixing assembly is used to fix the pipe. A pipe supporting assembly is arranged inside the working box, and the pipe supporting assembly is used to support the pipe when the grinding assembly grinds the pipe;

[0009] The pipe is fixed on the pipe fixing assembly, and then the pipe moving assembly is controlled to drive the welded part of the pipe to align with the grinding assembly in the working box. When the alignment is completed, the grinding assembly is started to grind the welded surface of the pipe. While the grinding assembly is grinding, the dust collection assembly centrally collects the dust ground by the grinding assembly through the air outlet groove plate, so as to centrally collect the dust ground by the grinding assembly in one place, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, thus polluting the working environment and harming the health of the operators. At the same time, while the grinding assembly grinds the pipe, the pipe supporting assembly supports the pipe to prevent the pipe from shifting in position due to the strain pressure generated during grinding, affecting the grinding effect.

[0010] Preferably, the solid material component includes axle boxes. There are two axle boxes, and the internal structures of the two axle boxes are the same. The two axle boxes are fixedly connected by a vertical rod. A set of limit sliding plates are fixedly installed on the inner walls of the two axle boxes. A set of clamping tube blocks are slidably connected to the inner walls of the two axle boxes. The outer walls of the two sets of clamping tube blocks are slidably connected to the inner walls of the two sets of limit sliding plates and the axle boxes respectively. A set of pushing blocks are fixedly installed on the outer walls of the two sets of clamping tube blocks. The pushing blocks are slidably connected to the inner walls of the axle boxes. A set of return springs are arranged between one side of the two sets of clamping tube blocks and the inner walls of the two axle boxes. One side of one of the axle boxes is fixedly connected to a limit disk. A groove box is fixedly installed on one side of the limit disk. A hydraulic cylinder is fixedly installed on the inner wall of the groove box. The output end of the hydraulic cylinder is fixedly installed with a shaft rod. The outer wall of the shaft rod is slidably connected to the inner walls of the limit disk and the two axle boxes. Two tapered shaft blocks are fixedly installed on the outer wall of the shaft rod. The outer walls of the two tapered shaft blocks are slidably connected to the outer walls of the two sets of pushing blocks respectively. One end outer walls of the two sets of pushing blocks are both inclined sliding surfaces. One side outer walls of the two sets of clamping tube blocks are both arc surfaces. When fixedly installing the pipe, pass the pipe through the two axle boxes so that one end of the pipe is flush with the limit disk. Then control the hydraulic cylinder to drive the shaft rod to expand and contract. While the shaft rod expands and contracts, it drives the two tapered shaft blocks to move in the two axle boxes. When the tapered shaft blocks move in the axle boxes, the tapered shaft blocks squeeze and push the multiple clamping tube blocks 206 in the axle boxes to move outwards, so that the multiple tapered shaft blocks drive the multiple clamping tube blocks to pull the multiple return springs to slide outwards in the limit sliding plates. When the multiple clamping tube blocks in the two axle boxes contact the inner wall of the pipe, stop the operation of the hydraulic cylinder. At this time, the multiple clamping tube blocks in the two axle boxes support the two ends of the inner wall of the pipe, thus realizing the fixation of the pipe. Fixing the pipe by moving the multiple clamping tube blocks can make the device applicable to fixing and installing pipes of different diameters and play a role in fixing pipes of different diameters.

[0011] Preferably, a rectangular box is slidably connected to the top of the support plate. A support seat is slidably connected to the inner wall of the rectangular box. A rotating pipe motor is fixedly installed on the top of the support seat. The output end of the rotating pipe motor is fixedly connected to one side of the groove box. When the pipe is fixed, control the moving component to align the welding part of the pipe to be polished with the polishing component. When the alignment is completed, control the rotating pipe motor to drive the groove box to rotate, so that the rotating pipe motor drives the pipe to rotate, which can accelerate the polishing speed of the pipe and also make the polishing component polish the welding surface of the pipe more comprehensively.

[0012] Preferably, the component for moving workpieces includes a torque adjustment motor. A displacement box is fixedly installed at the bottom of the support plate. The torque adjustment motor is fixedly installed on the inner wall of the displacement box. A screw shaft is fixedly installed at the output end of the torque adjustment motor. A displacement plate is threadedly connected to the outer wall of the screw shaft. The top end of the displacement plate is fixedly connected to the bottom of the torque box. The outer wall of the displacement plate is slidably connected to the inner wall of the support plate. When the pipe is fixed, the torque adjustment motor in the displacement box is controlled to drive the screw shaft to rotate. When the screw shaft rotates, the screw shaft drives the torque box to slide on the top of the support plate through the displacement plate by screw drive, so that the torque box pulls the pipe to move on the top of the support plate, thereby realizing the alignment of the welding part of the pipe with the grinding component and playing a role in adjusting and aligning.

[0013] Preferably, the grinding component includes a connecting frame. A grinding sand shaft is rotatably connected to the inner wall of the connecting frame. A fixing frame is fixedly installed on one side of the connecting frame. A bidirectional motor is fixedly installed on one side of the fixing frame. One end output of the bidirectional motor is fixedly connected to one side of the grinding sand shaft. The grinding sand shaft is placed above the side of the pipe. When the position of the pipe is aligned, the pipe rotation motor is controlled to drive the pipe to rotate. At the same time, the bidirectional motor drives the grinding sand shaft to rotate. When the grinding sand shaft rotates, the grinding sand shaft grinds the welding part of the pipe, playing a role in grinding.

[0014] Preferably, a hydraulic cylinder is fixedly installed on the top of the operation box. The output end of the hydraulic cylinder is fixedly connected to the top of the connecting frame. The outer wall of the connecting frame is slidably connected to the inner wall of the operation box. When it is necessary to grind the pipe, while the bidirectional motor drives the grinding sand shaft to rotate, the hydraulic cylinder drives the grinding sand shaft to move downward through the connecting frame. When the grinding sand shaft contacts the welding part of the pipe, the pipe and the grinding sand shaft rotate in opposite directions, so that the grinding sand shaft grinds the welding part of the pipe. At the same time, the hydraulic cylinder drives the grinding sand shaft to continue to move downward, so that the grinding sand shaft can continuously grind the welding part of the pipe, thereby completing the grinding operation of the welding position of the pipe and playing a role in controlling the feed of the grinding sand shaft.

[0015] Preferably, the dust collection assembly further includes a shaft disc, which is fixedly installed on the other side of the retaining frame. The other output end of the bidirectional motor is fixedly installed with an axial flow fan, and the axial flow fan is placed inside the shaft disc. The air outlet groove plate is fixedly installed on one side of the connecting frame, and the air outlet groove plate is placed above the side of the grinding sand shaft. There is a fixed connection of an air flow pipe between the air outlet groove plate and the shaft disc. When the bidirectional motor drives the grinding sand shaft to rotate to grind the pipe, the bidirectional motor also drives the axial flow fan to rotate. When the axial flow fan rotates, the axial flow fan will blow out air flow. Subsequently, through the continuous rotation of the axial flow fan, the air flow will enter the air outlet groove plate along the air flow pipe and finally blow out from the bottom of the air outlet groove plate. So when the grinding sand shaft grinds the pipe, the air flow blows out from the air outlet groove plate to blow the grinding part of the grinding sand shaft, thereby blowing the dust ground by the grinding sand shaft into the working box, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, flying into the air, polluting the working environment and harming the health of the operators, playing a role in preventing dust from floating out.

[0016] Preferably, the support member assembly includes branch support rods. The number of branch support rods is two, and both branch support rods are slidably connected to the inner wall of the support plate. The top of the support plate is fixedly installed with a strip-shaped frame plate, and a toothed column is rotatably connected inside the strip-shaped frame plate. The bottom of both branch support rods is fixedly installed with L-shaped toothed rods, and a rack bar is fixedly installed on the outer wall of the connecting frame. The teeth on the rack bar and the two L-shaped toothed rods are respectively engaged with the teeth on the toothed column. The top ends of both branch support rods can be attached to the outer wall of the pipe. When the hydraulic cylinder drives the grinding sand shaft to move down through the connecting frame, the hydraulic cylinder also drives the rack bar to move down through the connecting frame. When the rack bar moves down, it can drive the two L-shaped toothed rods to move up through the meshing transmission of the teeth, so that the L-shaped toothed rods drive the two branch support rods to move up, and the two branch support rods support the whole body of the pipe, preventing the pipe from shifting in position due to the strain pressure of the pipe being ground by the grinding sand shaft during rotation, affecting the grinding effect, and playing a role in supporting the pipe.

[0017] Preferably, a slag placement box is fixedly installed on the inner wall of the working box. A slag blocking plate is rotatably connected to the inner wall of the slag placement box. A push plate spring is arranged between the bottom of the slag blocking plate and the inner wall of the slag placement box. The bottom of the connecting frame is symmetrically fixedly installed with pressure rods, and the bottom ends of both pressure rods are placed directly above the slag blocking plate. When the hydraulic cylinder drives the grinding sand shaft to move down for grinding through the connecting frame, the connecting frame also drives the pressure rods at its bottom to move down. When the pressure rods move down, they push the slag blocking plate to squeeze the push plate spring and rotate in the slag placement box, so that the slag blocking plate opens in the slag placement box, providing an inlet for the dust to enter. When the operation is completed, the hydraulic cylinder drives the grinding sand shaft to reset, and the push plate spring will lose the extrusion of the pressure rod. Under the elastic push of the push plate spring, the slag blocking plate will rotate and close in the slag placement box, thereby closing the slag placement box, preventing the dust entering the slag placement box from floating out of the slag placement box, and playing a role in blocking the outflow of dust.

[0018] Preferably, a suction fan and a slag baffle are fixedly installed inside the slag disposal box. The suction fan is placed on one side of the slag baffle. When the air outlet trough plate blows the dust, the suction fan in the slag disposal box performs air extraction operation. Thus, when the dust is blown by the air outlet trough plate and enters the operation box, the suction fan extracts air to draw the dust, so that the dust enters the slag disposal box through the slag blocking plate, playing a role in cooperating with the air outlet trough plate for dust collection. The slag baffle is provided to block the dust and prevent the dust from contacting the slag disposal box and affecting the air extraction operation of the slag disposal box.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For a cylindrical building material grinding device described in the present invention, when the bidirectional motor drives the grinding sand shaft to rotate and grind the pipe, the bidirectional motor also drives the axial flow fan to rotate. When the axial flow fan rotates, the axial flow fan will blow out air flow. Subsequently, through the continuous rotation of the axial flow fan, the air flow will enter the air outlet trough plate along the air flow pipe and finally blow out from the bottom of the air outlet trough plate. When the grinding sand shaft grinds the pipe, the air flow blows out from the air outlet trough plate to blow the grinding area of the grinding sand shaft, thereby blowing the dust ground by the grinding sand shaft into the operation box, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, flying into the air, polluting the working environment and causing harm to the health of the operators.

[0021] 2. For a cylindrical building material grinding device described in the present invention, the pipe is passed through two shaft boxes, and one end of the pipe is flush with the limit disc. Subsequently, the hydraulic cylinder is controlled to drive the shaft rod to expand and contract. While the shaft rod expands and contracts, it drives two conical shaft blocks to move in the two shaft boxes. When the conical shaft blocks move in the shaft boxes, the conical shaft blocks squeeze and push multiple pipe clamping blocks in the shaft boxes to move outwards, so that the two conical shaft blocks drive the multiple pipe clamping blocks to pull multiple return springs to slide outwards in the limit slide plate. When the multiple pipe clamping blocks in the two shaft boxes contact the inner wall of the pipe, the multiple pipe clamping blocks in the two shaft boxes support the two ends of the inner wall of the pipe, thereby realizing the fixation of the pipe. By fixing the pipe through the movement of multiple pipe clamping blocks, the device can be applied to fix and install pipes with different diameters, playing a role in fixing pipes with different diameters.

[0022] 3. For a cylindrical building material grinding device described in the present invention, by controlling the torque adjustment motor in the displacement box to drive the screw shaft to rotate. When the screw shaft rotates, through screw thread transmission, the screw shaft drives the torque box to slide on the top of the support plate through the displacement plate, so that the torque box pulls the pipe to move on the top of the support plate, thereby realizing the alignment of the welding joint of the pipe with the grinding assembly, playing a role in adjusting and aligning the grinding position.

[0023] 4. For a cylindrical building material grinding device according to the present invention, when the hydraulic cylinder drives the grinding sand shaft to move downward through the connecting frame, the hydraulic cylinder also drives the rack bar to move downward through the connecting frame. When the rack bar moves downward, the two L-shaped tooth bars can be driven to move upward through the meshing transmission of the teeth, so that the L-shaped tooth bars drive the two branch pipe support bars to move upward, and the two branch pipe support bars support the whole body of the pipe, preventing the pipe from shifting in position due to the grinding strain pressure of the pipe by the grinding sand shaft during rotation, affecting the grinding effect, and playing the role of supporting the pipe.

[0024] 5. For a cylindrical building material grinding device according to the present invention, when the hydraulic cylinder drives the grinding sand shaft to move downward for grinding, the hydraulic cylinder also drives the pressure rod to move downward, thereby pushing the slag blocking plate to squeeze the push plate spring and rotate in the slag placing box, so that the slag blocking plate opens in the slag placing box, providing an inlet for the dust to enter. When the operation is completed, the hydraulic cylinder drives the grinding sand shaft to reset, and the push plate spring will lose the extrusion of the pressure rod. Under the elastic push of the push plate spring, the slag blocking plate will rotate and close in the slag placing box, thereby closing the slag placing box and preventing the dust entering the slag placing box from floating out of the slag placing box, playing the role of blocking the outflow of dust.

[0036] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0037] As Figures 1 to 9 shown, a cylindrical building material grinding device according to an embodiment of the present invention includes a support plate 1. A top of the support plate 1 is fixedly installed with an operation box 3. A grinding assembly is arranged inside the operation box 3. The grinding assembly is used for grinding a welded surface of a pipe. A dust collection assembly is arranged inside the operation box 3. The dust collection assembly is arranged on one side of the grinding assembly. The dust collection assembly includes an air outlet groove plate 501. The dust collection assembly is used for centrally collecting dust ground by the grinding assembly through the air outlet groove plate 501. A component shifting assembly is arranged on one side of the top of the support plate 1. The component shifting assembly is used for driving the pipe to align with the grinding assembly in position. A component fixing assembly is arranged outside the component shifting assembly. The component fixing assembly is used for fixing the pipe in position. A component supporting assembly is arranged inside the operation box 3. The component supporting assembly is used for supporting the pipe when the grinding assembly grinds the pipe.

[0038] Due to the uncertainty of the direction and speed of dust generation, part of the dust cannot be removed in time, thus polluting the working environment and causing harm to the health of operators.

[0039] By fixing the pipe to the fixed material component, then controlling the moving component to drive the welding part of the pipe to align with the grinding component in the operation box 3. When the alignment is completed, the grinding component is started to grind the welding surface of the pipe. While the grinding component is grinding, the dust collection component collects the dust ground by the grinding component through the air outlet groove plate 501, so as to collect the dust ground by the grinding component in one place, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, thus polluting the working environment and harming the health of the operators. At the same time, while the grinding component is grinding the pipe, the supporting component supports the pipe to prevent the position of the pipe from shifting due to the strain pressure generated during grinding, affecting the grinding effect. It should be noted here that the cylindrical building material processed by this solution is a metal pipe.

[0040] As Figures 3 to 5 shown, the fixed material component includes shaft boxes 202. The number of shaft boxes 202 is two. The internal structures of the two shaft boxes 202 are the same. The two shaft boxes 202 are fixedly connected by a vertical rod. A group of limit slide plates 2010 are fixedly installed on the inner walls of the two shaft boxes 202. A group of pipe clamping blocks 206 are slidably connected to the inner walls of the two shaft boxes 202. The outer walls of the two groups of pipe clamping blocks 206 are slidably connected to the outer walls of the two groups of limit slide plates 2010 and the inner walls of the shaft boxes 202 respectively. A group of push blocks 208 are fixedly installed on the outer walls of the two groups of pipe clamping blocks 206. The push blocks 208 are slidably connected to the inner walls of the shaft boxes 202. A group of return springs 209 are arranged between one side of the two groups of pipe clamping blocks 206 and the inner walls of the two shaft boxes 202 respectively. One side of one of the shaft boxes 202 is fixedly connected to a limit disc 2. A groove box 205 is fixedly installed on one side of the limit disc 2. A hydraulic cylinder 204 is fixedly installed on the inner wall of the groove box 205. The output end of the hydraulic cylinder 204 is fixedly installed with a shaft rod 203. The outer wall of the shaft rod 203 is slidably connected to the inner walls of the limit disc 2 and the two shaft boxes 202. Two conical shaft blocks 207 are fixedly installed on the outer wall of the shaft rod 203. The outer walls of the two conical shaft blocks 207 are slidably connected to the outer walls of the two groups of push blocks 208 respectively. One end outer walls of the two groups of push blocks 208 are inclined sliding surfaces. One side outer walls of the two groups of pipe clamping blocks 206 are arc surfaces;

[0041] When the pipe is fixedly installed, the pipe is passed through two shaft boxes 202, and one end of the pipe is flush with the limit disc 2. Subsequently, the hydraulic cylinder 204 is controlled to drive the shaft rod 203 to expand and contract. While the shaft rod 203 expands and contracts, it drives two tapered shaft blocks 207 to move within the two shaft boxes 202. When the tapered shaft blocks 207 move within the shaft boxes 202, the tapered shaft blocks 207 squeeze and push multiple pipe clamping blocks 206 within the shaft boxes 202 to move outward. Thus, the two tapered shaft blocks 207 drive multiple pipe clamping blocks 206 to pull multiple return springs 209 to slide outward within the limit slide plate 2010. When multiple pipe clamping blocks 206 within the two shaft boxes 202 contact the inner wall of the pipe, the operation of the hydraulic cylinder 204 is stopped. At this time, multiple pipe clamping blocks 206 within the two shaft boxes 202 support both ends of the inner wall of the pipe, thereby realizing the fixation of the pipe. By using the movement of multiple pipe clamping blocks 206 to fix the pipe, this device can be applied to fixedly install pipes with different diameters and play a role in fixing pipes with different diameters.

[0042] As Figures 4 to 5 shown, a rectangular box 804 is slidably connected to the top of the support plate 1. A support seat is slidably connected to the inner wall of the rectangular box 804. A rotating pipe motor 201 is fixedly installed at the top of the support seat. The output end of the rotating pipe motor 201 is fixedly connected to one side of the groove box 205;

[0043] When the pipe fixation is completed, the position of the welding joint of the pipe to be polished is aligned with the polishing component by controlling the moving component. When the alignment is completed, the rotating pipe motor 201 is controlled to drive the groove box 205 to rotate, thereby driving the pipe to rotate by the rotating pipe motor 201. This can accelerate the polishing speed of the pipe and also enable the polishing component to polish the welding surface of the pipe more comprehensively.

[0044] As Figures 1 to 2 shown, the moving component includes a torque adjusting motor 801. A displacement box 8 is fixedly installed at the bottom of the support plate 1. The torque adjusting motor 801 is fixedly installed on the inner wall of the displacement box 8. The output end of the torque adjusting motor 801 is fixedly installed with a screw shaft 802. A displacement plate 803 is threadedly connected to the outer wall of the screw shaft 802. The top end of the displacement plate 803 is fixedly connected to the bottom of the rectangular box 804. The outer wall of the displacement plate 803 is slidably connected to the inner wall of the support plate 1;

[0045] When the pipe fixation is completed, the torque adjusting motor 801 within the displacement box 8 is controlled to drive the screw shaft 802 to rotate. When the screw shaft 802 rotates, through screw transmission, the screw shaft 802 drives the rectangular box 804 to slide on the top of the support plate 1 through the displacement plate 803, so that the rectangular box 804 pulls the pipe to move on the top of the support plate 1, thereby realizing the alignment of the welding joint of the pipe with the polishing component and playing a role in adjusting and aligning.

[0046] As Figures 6 to 8As shown in the figure, the grinding assembly includes a connecting frame 302. A grinding sand shaft 7 is rotatably connected to the inner wall of the connecting frame 302. A retaining frame 702 is fixedly installed on one side of the connecting frame 302. A bidirectional motor 701 is fixedly installed on one side of the retaining frame 702. One output end of the bidirectional motor 701 is fixedly connected to one side of the grinding sand shaft 7. The grinding sand shaft 7 is placed above the side of the pipe.

[0047] When the position of the pipe is calibrated, the control rotating pipe motor 201 drives the pipe to rotate. At the same time, the bidirectional motor 701 drives the grinding sand shaft 7 to rotate. When the grinding sand shaft 7 rotates, the grinding sand shaft 7 grinds the welded joint of the pipe, playing a role in grinding. It should be noted here that the direction in which the rotating pipe motor 201 drives the pipe to rotate is opposite to the direction in which the grinding sand shaft 7 rotates.

[0048] As Figures 6 to 7 As shown in the figure, a hydraulic cylinder 301 is fixedly installed on the top of the operation box 3. The output end of the hydraulic cylinder 301 is fixedly connected to the top of the connecting frame 302. The outer wall of the connecting frame 302 is slidably connected to the inner wall of the operation box 3.

[0049] Since the position of the welded joint of the pipe is higher than the height of the pipe, when the pipe needs to be ground, while the bidirectional motor 701 drives the grinding sand shaft 7 to rotate, the hydraulic cylinder 301 drives the grinding sand shaft 7 to move downward through the connecting frame 302. When the grinding sand shaft 7 contacts the welded joint of the pipe, due to the opposite rotation of the pipe and the grinding sand shaft 7, the grinding sand shaft 7 grinds the welded joint of the pipe. At the same time, by driving the grinding sand shaft 7 to continuously move downward through the hydraulic cylinder 301, the grinding sand shaft 7 can continuously grind the welded joint of the pipe, thus completing the grinding operation of the welded position of the pipe, playing a role in controlling the feed of the grinding sand shaft 7.

[0050] As Figures 6 to 8 As shown in the figure, the dust collection assembly further includes a shaft disc 502. The shaft disc 502 is fixedly installed on the other side of the retaining frame 702. Another output end of the bidirectional motor 701 is fixedly installed with an axial flow fan 503. The axial flow fan 503 is placed inside the shaft disc 502. An air outlet trough plate 501 is fixedly installed on one side of the connecting frame 302. The air outlet trough plate 501 is placed above the side of the grinding sand shaft 7. An air flow pipe 5 is fixedly connected between the air outlet trough plate 501 and the shaft disc 502.

[0051] When the bidirectional motor 701 drives the grinding sand shaft 7 to rotate for grinding the pipe, the bidirectional motor 701 also drives the axial flow fan 503 to rotate. When the axial flow fan 503 rotates, the axial flow fan 503 will blow out air flow. Subsequently, through the continuous rotation of the axial flow fan 503, the air flow will enter the air outlet trough plate 501 along the air flow pipe 5 and finally blow out from the bottom of the air outlet trough plate 501. When the grinding sand shaft 7 grinds the pipe, the air flow blows out from the air outlet trough plate 501 to blow the grinding part of the grinding sand shaft 7, so as to blow the dust ground by the grinding sand shaft 7 into the operation box 3, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, thus flying into the air, polluting the working environment and causing harm to the health of the operators, playing a role in preventing the dust from floating out. Here, it should be noted that the angle of the air outlet opening at the bottom of the air outlet trough plate 501 is the same as the grinding angle of the grinding sand shaft 7, and a plurality of air flow inlets are provided on the inner wall of the shaft disk 502.

[0052] As Figures 6 to 7 shown, the supporting member assembly includes branch pipe support rods 6. The number of the branch pipe support rods 6 is two. Both of the two branch pipe support rods 6 are slidably connected to the inner wall of the support plate 1. A strip-shaped frame plate 604 is fixedly installed at the top of the support plate 1. A tooth column 602 is rotatably connected inside the strip-shaped frame plate 604. L-shaped tooth rods 601 are fixedly installed at the bottoms of both of the two branch pipe support rods 6. A rack bar 603 is fixedly installed on the outer wall of the connecting frame 302. The teeth on the rack bar 603 and the two L-shaped tooth rods 601 are respectively meshed with the teeth on the tooth column 602. The tops of both of the two branch pipe support rods 6 can be attached to the outer wall of the pipe.

[0053] When the hydraulic cylinder 301 drives the grinding sand shaft 7 to move downward through the connecting frame 302, the hydraulic cylinder 301 also drives the rack bar 603 to move downward through the connecting frame 302. When the rack bar 603 moves downward, the two L-shaped tooth rods 601 can be driven to move upward through the meshing transmission of the teeth, so that the L-shaped tooth rods 601 drive the two branch pipe support rods 6 to move upward, and the two branch pipe support rods 6 support the whole body of the pipe, preventing the pipe from shifting in position due to the grinding strain pressure of the pipe by the grinding sand shaft 7 during rotation, affecting the grinding effect, and playing a role in supporting the pipe.

[0054] As Figures 8 to 9 shown, a slag disposal box 4 is fixedly installed on the inner wall of the operation box 3. A slag blocking plate 403 is rotatably connected to the inner wall of the slag disposal box 4. A push plate spring 404 is arranged between the bottom of the slag blocking plate 403 and the inner wall of the slag disposal box 4. Pressure rods 405 are symmetrically and fixedly installed at the bottom of the connecting frame 302. The bottom ends of both of the two pressure rods 405 are placed directly above the slag blocking plate 403.

[0055] When the hydraulic cylinder 301 drives the grinding sand shaft 7 to move down for grinding through the connecting frame 302, the connecting frame 302 also drives the pressure rod 405 at its bottom to move down. When the pressure rod 405 moves down, it pushes the slag blocking plate 403 to squeeze the push plate spring 404 and rotate in the slag storage box 4, so that the slag blocking plate 403 opens in the slag storage box 4, providing an inlet for the dust to enter. When the operation is completed, the hydraulic cylinder 301 drives the grinding sand shaft 7 to reset, and the push plate spring 404 will lose the extrusion of the pressure rod 405. Under the elastic push of the push plate spring 404, the slag blocking plate 403 will rotate and close in the slag storage box 4, thus closing the slag storage box 4 to prevent the dust entering the slag storage box 4 from floating out of the slag storage box 4, playing a role in blocking the outflow of dust.

[0056] As Figures 8 to 9 shown, a suction fan 401 and a slag blocking plate 402 are fixedly installed inside the slag storage box 4, and the suction fan 401 is placed on one side of the slag blocking plate 402;

[0057] When the air outlet groove plate 501 blows the dust, the suction fan 401 in the slag storage box 4 performs a suction operation. Thus, when the dust is blown by the air outlet groove plate 501 and enters the operation box 3, the suction fan 401 sucks air to draw the dust, so that the dust enters the slag storage box 4 through the slag blocking plate 403, playing a role in cooperating with the air outlet groove plate 501 for dust collection. The setting of the slag blocking plate 402 is to block the dust and prevent the dust from contacting the slag storage box 4 and affecting the suction operation of the slag storage box 4.

[0058] Working principle: Fix the pipe on the fixed material component, and then control the moving component to drive the welding part of the pipe to align with the grinding component in the operation box 3. When the alignment is completed, start the grinding component to grind the welding surface of the pipe. While the grinding component is grinding, the dust collection component collects the dust ground by the grinding component through the air outlet groove plate 501, so as to concentrate the dust ground by the grinding component in one place, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, thus polluting the working environment and endangering the health of the operators. At the same time, while the grinding component grinds the pipe, the pipe supporting component supports the pipe to prevent the pipe from shifting in position due to the strain pressure generated during grinding, affecting the grinding effect;

[0059] When the pipe is fixedly installed, the pipe is passed through two shaft boxes 202, and one end of the pipe is flush with the limit disc 2. Subsequently, the hydraulic cylinder 204 is controlled to drive the shaft rod 203 to expand and contract. While the shaft rod 203 expands and contracts, it drives two tapered shaft blocks 207 to move within the two shaft boxes 202. When the tapered shaft blocks 207 move within the shaft boxes 202, the tapered shaft blocks 207 squeeze and push multiple pipe clamping blocks 206 within the shaft boxes 202 to move outward, so that the two tapered shaft blocks 207 drive multiple pipe clamping blocks 206 to pull multiple return springs 209 to slide outward within the limit slide plate 2010. When multiple pipe clamping blocks 206 within the two shaft boxes 202 contact the inner wall of the pipe, the operation of the hydraulic cylinder 204 is stopped. At this time, multiple pipe clamping blocks 206 within the two shaft boxes 202 support both ends of the inner wall of the pipe, thereby realizing the fixation of the pipe. By moving multiple pipe clamping blocks 206 to fix the pipe, the device can be applied to fixedly install pipes of different diameters and play a role in fixing pipes of different diameters;

[0060] When the pipe fixation is completed, the control moving component is used to align the welding part of the pipe to be polished with the polishing component. When the alignment is completed, the rotating pipe motor 201 is controlled to drive the groove box 205 to rotate, so that the rotating pipe motor 201 drives the pipe to rotate, which can accelerate the polishing speed of the pipe and also enable the polishing component to polish the welding surface of the pipe more comprehensively;

[0061] When the pipe fixation is completed, the torque adjustment motor 801 within the displacement box 8 is controlled to drive the screw shaft 802 to rotate. When the screw shaft 802 rotates, through screw drive, the screw shaft 802 drives the torque box 804 to slide on the top of the support plate 1 through the displacement plate 803, so that the torque box 804 pulls the pipe to move on the top of the support plate 1, thereby realizing the alignment of the welding part of the pipe with the polishing component and playing a role in adjusting and aligning;

[0062] When the pipe position alignment is completed, the rotating pipe motor 201 is controlled to drive the pipe to rotate, and at the same time, the bidirectional motor 701 drives the polishing sand shaft 7 to rotate. When the polishing sand shaft 7 rotates, the polishing sand shaft 7 polishes the welding part of the pipe and plays a role in polishing;

[0063] When the pipe needs to be polished, while the bidirectional motor 701 drives the polishing sand shaft 7 to rotate, the hydraulic cylinder 301 drives the polishing sand shaft 7 to move downward through the connecting frame 302. When the polishing sand shaft 7 contacts the welding part of the pipe, due to the opposite rotation of the pipe and the polishing sand shaft 7, the polishing sand shaft 7 polishes the welding part of the pipe. At the same time, by driving the polishing sand shaft 7 to continuously move downward through the hydraulic cylinder 301, the polishing sand shaft 7 can continuously polish the welding part of the pipe, thereby completing the polishing operation of the welding position of the pipe and playing a role in controlling the feed of the polishing sand shaft 7;

[0064] When the bidirectional motor 701 drives the grinding sand shaft 7 to rotate to grind the pipe, the bidirectional motor 701 also drives the axial flow fan 503 to rotate. When the axial flow fan 503 rotates, the axial flow fan 503 will blow out air. Subsequently, through the continuous rotation of the axial flow fan 503, the air flow will enter the air outlet groove plate 501 along the air flow pipe 5 and finally blow out from the bottom of the air outlet groove plate 501. When the grinding sand shaft 7 grinds the pipe, the air flow blows out from the air outlet groove plate 501 to blow the grinding area of the grinding sand shaft 7, so as to blow the dust ground by the grinding sand shaft 7 into the operation box 3, preventing some dust from not being sucked in time due to the uncertainty of the direction and speed of the dust generation, flying into the air, polluting the working environment and harming the health of the operators, thus playing a role in preventing dust from floating out;

[0065] When the hydraulic cylinder 301 drives the grinding sand shaft 7 to move downward through the connecting frame 302, the hydraulic cylinder 301 also drives the rack bar 603 to move downward through the connecting frame 302. When the rack bar 603 moves downward, it can drive the two L-shaped rack bars 601 to move upward through the meshing transmission of the teeth, so that the L-shaped rack bars 601 drive the two branch pipe support bars 6 to move upward, and the two branch pipe support bars 6 support the whole body of the pipe, preventing the pipe from shifting in position due to the grinding strain pressure of the pipe by the grinding sand shaft 7 during rotation and affecting the grinding effect, thus playing a role in supporting the pipe;

[0066] When the hydraulic cylinder 301 drives the grinding sand shaft 7 to move downward for grinding through the connecting frame 302, the connecting frame 302 also drives the pressure rod 405 at its bottom to move downward. When the pressure rod 405 moves downward, it pushes the slag blocking plate 403 to squeeze the push plate spring 404 and rotate in the slag placing box 4, so that the slag blocking plate 403 opens in the slag placing box 4 to provide an inlet for the dust to enter. When the operation is completed, the hydraulic cylinder 301 drives the grinding sand shaft 7 to reset, and the push plate spring 404 will lose the extrusion of the pressure rod 405. Under the elastic push of the push plate spring 404, the slag blocking plate 403 will rotate and close in the slag placing box 4, thus closing the slag placing box 4 to prevent the dust entering the slag placing box 4 from floating out of the slag placing box 4, playing a role in blocking the outflow of dust;

[0067] When the air outlet groove plate 501 blows the dust, the exhaust fan 401 in the slag placing box 4 performs an exhaust operation. So when the dust is blown into the operation box 3 by the air outlet groove plate 501, the exhaust fan 401 exhausts air to draw the dust, so that the dust enters the slag placing box 4 through the slag blocking plate 403, playing a role in cooperating with the air outlet groove plate 501 for dust collection. The setting of the slag blocking plate 402 is to block the dust and prevent the dust from contacting the slag placing box 4 and affecting the exhaust operation of the slag placing box 4.
