Description

Technical Field

[0001] The utility model relates to the field of polishing devices, in particular to a pipeline polishing device with a cleaning structure. Background Art

[0002] A natural gas pipeline is a pipeline that transports natural gas from the extraction site or processing plant to the city's gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. During installation and connection, the natural gas pipeline needs to be polished to increase its sealing performance.

[0003] A search revealed a Chinese patent application (publication number CN 112059760B) that discloses a novel pipe grinding device. This patented technology involves rotating a drive disc, which drives a grinding mechanism to reciprocate along the length of the pipe via a connecting rod to increase the grinding area. When the drive gear rotates against the direction of rotation of the ratchet, it drives the rotating seat to rotate a certain angle around the central axis to increase the grinding process. When the drive gear rotates in the direction of rotation of the ratchet, the rotating seat and the central axis remain stationary relative to each other, increasing the contact time between the grinding mechanism and the same portion of the pipe.

[0004] However, in the technical solution of the above patent document, a lot of dust will still be generated and float in the air when the pipeline is polished, which is easy to be touched by workers when disassembling and installing the pipeline.

[0005] Therefore, a pipeline polishing device with a cleaning structure is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a pipe grinding device with a cleaning structure in order to solve the above problems, thereby improving the problem that a lot of dust will still be generated floating in the air during the grinding operation of the pipe, which is easy to be touched by workers when disassembling and installing the pipe.

[0008] Preferably, the fitting component includes an installation groove arranged at the lower end of the pushing seat, the inner wall of the installation groove is rotatably connected with a two-way stud, one end of the two-way stud rotates to pass through the side end of the pushing seat and extends outward, the circumferential surface of the two-way stud is threadedly connected to two pushing sliders, the lower ends of the two pushing sliders are fixedly connected to a fixing plate, the adjacent ends of the two fixing plates are fixedly connected to a first spring, and the adjacent ends of the two first springs are fixedly connected to a sponge smearing block, and the fitting component can be used to fit both sides of the pipeline, and when the main machine rotates and moves the pipeline, moisture is applied to the surface of the pipeline to absorb powder generated by grinding so that the powder will not be emitted outward.

[0009] Preferably, the side ends of the two sponge smearing blocks are fixedly connected with telescopic rods, and the two telescopic rods are respectively fixedly connected to the two fixed plates.

[0010] Preferably, the inner wall of the mounting groove is fixedly connected with a rotating seat, and the bidirectional stud is rotatably connected to the inner wall of the rotating seat. The rotating seat can make the rotation of the bidirectional stud more stable and reduce the swing during rotation.

[0011] Preferably, the limiting assembly includes a limiting slider fixedly connected to the side end of the pushing slider, and a limiting slot is provided on the inner wall of the mounting groove. The limiting slider slides in cooperation with the limiting slot. The limiting assembly can make the fitting assembly less likely to tilt and more stable when fitting assembly fits the pipe surface.

[0012] Preferably, the locking mechanism includes a gear fixedly connected to the surface of the bidirectional stud, a mounting block fixedly connected to the side end of the pushing seat, a second spring fixedly connected to one side end of the mounting block close to the gear, and one end of the second spring fixedly connected to a fitting tooth block, the fitting tooth block engages with the surface of the gear, and the locking mechanism can lock the rotation of the bidirectional stud, making it difficult for the bidirectional stud to rotate on its own, preventing the bidirectional stud from loosening its fixation on the pipeline when the pipeline moves.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 As shown, a pipe polishing device with a cleaning structure comprises: a main unit 1, the side end of the main unit 1 is fixedly connected to a pushing seat 2 and an internal fixing device 3, and the lower end of the pushing seat 2 is fixedly connected to a polishing wheel 6; a fitting and smearing mechanism 4, which is used to apply moisture to the surface of the pipe while the pushing seat 2 is fitting and polishing the pipe, and the fitting and smearing mechanism 4 for wiping off adsorbed dust is arranged on one side of the pushing seat 2; a locking mechanism 5, which is used to stably fit the fitting and smearing mechanism 4 to the surface of the pipe, and the locking mechanism 5 is arranged on one side of the pushing seat 2; wherein, the fitting and smearing mechanism 4 comprises a fitting component 401 arranged on one side of the pushing seat 2, and a limiting component 402 is arranged on one side of the fitting component 401. When the pipe needs to be polished, the pipe is fixed by the internal fixing device 3, and then the pipe is fitted by the fitting component 401, and the limiting component 402 is fitted to the fitting component 401. The fitting component 401 is limited to prevent it from tilting when fitting the pipe, and the locking mechanism 5 is used to prevent the fitting component 401 from loosening during the grinding process. At this time, the main unit 1 is started to drive the internal fixing device 3 and the pipe to move and rub against the grinding wheel 6 for grinding. While the pipe rotates, the fitting component 401 applies water to the surface of the pipe to absorb the dust generated by grinding and reduce the emission of dust. The main unit 1 includes a button controller for the motor that drives the internal fixing device 3. The main unit 1 can drive the internal fixing device 3 to rotate so that the push seat 2 contacts the pipe for one circle for grinding. The internal fixing device 3 can fix the pipe from the inside of the pipe, so that when the main unit 1 rotates the internal fixing device 3, the pipe rotates at the same time for grinding. For people working in this technical field, the main unit 1 and the grinding wheel 6 are both existing technologies and will not be described in detail here.

[0025] like Figure 1 and Figure 3As shown, the fitting component 401 includes a mounting groove 4014 provided at the lower end of the pushing seat 2, the inner wall of the mounting groove 4014 is rotatably connected with a two-way stud 4011, one end of the two-way stud 4011 rotates through the side end of the pushing seat 2 and extends outward, the circumferential surface of the two-way stud 4011 is threadedly connected with two pushing sliders 4012, the lower ends of the two pushing sliders 4012 are fixedly connected with a fixing plate 4013, the adjacent ends of the two fixing plates 4013 are fixedly connected with a first spring 4015, and the adjacent ends of the two first springs 4015 are fixedly connected with a sponge smearing block 4016. When you want to apply water to the surface of the fitting component 401 to absorb dust, at this time, by rotating the two-way stud 4011, the two-way stud The two ends of 4011 have screws in opposite directions, so the two-way stud 4011 drives the two pushing sliders 4012 and the fixing plate 4013 to approach each other, and the two fixing plates 4013 drive the sponge smearing blocks 4016 to approach each other to fit the surface of the pipe. The sponge smearing blocks 4016 can absorb a large amount of water flow. At this time, they are squeezed by the first spring 4015 and the movement of the pipe, and the water flow is smeared on the surface of the pipe. When the pipe is polished, dust is absorbed. The side ends of the two sponge smearing blocks 4016 are fixedly connected with telescopic rods 4017. The two telescopic rods 4017 are fixedly connected to the two fixing plates 4013 respectively. The two first springs 4015 are respectively sleeved on the circumferential surfaces of the two telescopic rods 4017. When the two fixing plates 4013 are close to each other, the sponge smearing blocks 4016 can absorb a large amount of water flow. At this time, they are squeezed by the first spring 4015 and the movement of the pipe, and the water flow is applied to the surface of the pipe. When the pipe is polished, dust is absorbed. When the first spring 4015 and the sponge smearing block 4016 are close to each other and are pushed to fit the surface of the pipe, the first spring 4015 is squeezed and easily elastically deformed, resulting in damage. The first spring 4015 is supported by the telescopic rod 4017, so that the first spring 4015 is not easily elastically deformed. The inner wall of the mounting groove 4014 is fixedly connected with the rotating seat 7, and the two-way stud 4011 is rotatably connected to the inner wall of the rotating seat 7. When the two-way stud 4011 rotates, the two-way stud 4011 is long in length and is affected by the gravity of the fixed plate 4013. After long-term use, it is easy to bend and swing. The rotation of the two-way stud 4011 is supported and limited by the rotating seat 7, so that the two-way stud 4011 is subjected to long-term The fixed plate 4013 is acted upon by gravity, so it is not easy to bend or swing. The limiting assembly 402 includes a limiting slider 4021 fixedly connected to the side end of the pushing slider 4012. A limiting slot 4022 is provided on the inner wall of the mounting groove 4014. The limiting slider 4021 slides with the limiting slot 4022. When the pushing slider 4012 is rotated and approaches each other by the two-way stud 4011, the pushing slider 4012 easily swings following the rotation of the two-way stud 4011. When the pushing slider 4012 moves, the limiting slider 4021 is driven to slide on the inner wall of the limiting slot 4022, so that when the two-way stud 4011 drives the pushing slider 4012 to move, the sliding of the pushing slider 4012 is more stable and not easy to swing.

[0026] like Figure 4When the gear 501 is unlocked, the locking mechanism 502 is locked and the locking mechanism 501 is unlocked. When the two-way stud 4011 is rotated, the locking lever 505 is fixed to the second spring 504, so that the second spring 504 is not easily deformed.

[0027] When the present invention is in use, when it is necessary to grind the pipe, the pipe is fixed by the internal fixing device 3, and then the unlocking rod 505 is pulled, and the fixing block 506 and the unlocking rod 505 are simply fixed by the blocking block 508. At this time, the two-way stud 4011 is rotated, so that the two-way stud 4011 drives the two pushing sliders 4012 and the fixing plate 4013 to approach each other, and the two fixing plates 4013 drive the two first springs 4015 and the sponge smearing block 4016 to approach each other and fit the pipe surface. At this time, the main unit 1 is started, and the main unit 1 drives the internal fixing device 3 and the pipe to rotate, contacting the grinding wheel 6 for grinding operation, and at the same time, the water absorbed by the sponge smearing block 4016 smears the pipe surface as the pipe rotates, absorbs the dust emitted by grinding, and reduces the dust that the workers are exposed to when the pipe grinding is completed.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
