Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to a grinding device for the surface of stainless steel pipes used in communication tower processing. Background Technology

[0002] A communication tower, also called a signal transmission tower or signal tower, is mainly used to support signal transmitting antennas, erect the antennas at high places, increase the coverage and strength of the signal, and ensure the normal operation of wireless communication systems. It is widely used by mobile, China Unicom, China Telecom and other communication departments.

[0003] Currently, steel pipes are widely used as supporting components in the manufacturing process of communication towers to bear the weight of the tower itself, antennas, and other equipment, as well as external forces such as wind loads and seismic loads. Before manufacturing, the steel pipes undergo an internal and external wall grinding process to remove rust and stains, and a corrosion-resistant coating is applied to enhance the tower's corrosion resistance and extend its service life. Nowadays, the internal wall grinding of steel pipes typically involves inserting a grinding wheel into the pipe, bringing the wheel into contact with the inner wall, and slowly advancing along the pipe's axis while the pipe itself rotates slowly to evenly grind all areas of the inner wall.

[0004] However, the grinding process generates a lot of debris and powder. If this debris and powder accumulate inside the steel pipe and are not cleaned, it can easily fly out and pollute the external environment during subsequent installation and transportation. Furthermore, because the steel pipe itself rotates at a constant speed during grinding, the debris and powder move with the pipe and easily fall onto the grinding equipment, contaminating it and causing difficulties for subsequent cleaning. Therefore, we propose a surface grinding device for stainless steel pipes used in communication tower processing to effectively solve these problems. Summary of the Invention

[0005] The purpose of this invention is to provide a surface grinding device for stainless steel pipes used in communication tower processing, which solves the problems mentioned in the background art.

[0013] Optionally, a main shaft is rotatably provided at the center of the disk, one end of the main shaft extends into the mounting groove and is coaxially connected to the first gear, and the other end of the main shaft is connected to the drive shaft.

[0014] Optionally, the vacuuming assembly includes a vacuum hood, on which a displacement frame is fixedly mounted, and an arc-shaped guide rail is provided on the outer surface of the disc, the center of the arc-shaped guide rail being coincident with the center of the disc, and the displacement frame slidingly engaging with the arc-shaped guide rail;

[0015] The displacement frame is also equipped with an iron block, and electromagnets for attracting the iron block are provided on the surface of the disc and at both ends of the arc-shaped guide rail. The two ends of the arc-shaped guide rail are A and B, respectively. When the displacement frame is located at A, the dust suction hood is located at the lower right of the disc and the opening of the dust suction hood faces left. When the displacement frame is located at B, the dust suction hood is located at the left side of the disc and the opening of the dust suction hood faces upward.

[0016] Optionally, a protective sleeve is provided on the outside of the drive shaft, and a stabilizing ring is rotatably sleeved on the outside of the drive shaft via a bearing.

[0018] Optionally, the disc is provided with a power supply for powering the electromagnets, and two microswitches are respectively provided at the upper and lower ends of the displacement groove. The two microswitches are connected in series with the two electromagnets respectively. When the slider abuts against the microswitch at the bottom of the displacement groove, the electromagnet at the A end of the arc-shaped guide rail is energized. When the slider abuts against the microswitch at the top of the displacement groove, the electromagnet at the B end of the arc-shaped guide rail is energized.

[0021] Compared with the prior art, the present invention provides a surface grinding device for stainless steel pipes used in communication tower processing, which has the following advantages:

[0022] 1. The present invention provides a dust collection component on the grinding component. The dust collection component can absorb the debris generated during the grinding process, thereby preventing the debris from remaining inside the steel pipe and causing the debris to fall to the outside during installation and transportation, resulting in environmental pollution.

[0023] 2. In this invention, the dust hood can switch back and forth between two positions. Specifically, when the grinding component grinds the bottom wall of the steel pipe, the dust hood is located at the lower right of the grinding component, and when the grinding component grinds the top wall of the steel pipe, the dust hood is located at the left side of the grinding component, so as to adapt to the distribution of debris under different grinding conditions and help improve the debris absorption effect.

[0024] 3. When the dust hood in this invention is located at the lower right of the grinding assembly, the opening width of the dust hood is narrow, which helps to enhance the negative pressure and improve the debris absorption rate. When the dust hood is located on the left side of the grinding assembly, the opening width of the dust hood is larger, which helps to expand the debris absorption range and further improve the debris absorption rate.

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1 - Figure 9A surface grinding device for stainless steel pipes used in communication tower processing includes a base 100 and a pipe support and rotation mechanism 200. The pipe support and rotation mechanism 200 is disposed on one side of the top surface of the base 100 and is used to support the pipe to lie flat and control the pipe to rotate around its own central axis. Specifically, there are at least two pipe support and rotation mechanisms 200, and each pipe support and rotation mechanism 200 includes two oppositely distributed rollers and a motor capable of driving the rollers to rotate. When the steel pipe is laid flat on the two rollers, the steel pipe can be driven to rotate at a uniform speed as the rollers rotate.

[0037] This embodiment also includes a slide 300 and a grinding mechanism 400. The slide 300 is slidably disposed on the top surface of the base 100. The top surface of the slide 300 is also provided with a support platform 301 that can be raised and lowered vertically. Support columns 302 are provided on both the front and rear sides of the top surface of the slide 300, and the support platform 301 is slidably engaged with the support columns 302. The top surface of the slide 300 is also provided with a first linear drive assembly 303, which is used to push the support platform 301 to slide up and down. In this embodiment, the first linear drive assembly 303 is a cylinder or a hydraulic cylinder, the cylinder body of which is fixedly connected to the slide 300, and its movable end is connected to the bottom surface of the support platform 301.

[0038] Furthermore, the polishing mechanism 400 includes a motor 401, a drive shaft 402, and a polishing assembly 403. The motor 401 is fixedly mounted on the top surface of the support platform 301 via a motor mount. The output shaft of the motor 401 is connected to the polishing assembly 403 via the drive shaft 402. That is, both ends of the drive shaft 402 are connected to the output shaft of the motor 401 and the polishing assembly 403, respectively.

[0039] Specifically, the grinding assembly 403 includes a disc 4031 and a grinding ring 4032 rotatably sleeved on the outside of the disc 4031. The grinding ring 4032 is made of silicon carbide, while the disc 4031 is made of aluminum alloy. A mounting groove 4033 is formed on the outer ring wall of the disc 4031. A first gear 4034 and a second gear 4035 are rotatably mounted within the mounting groove 4033, meshing with each other. A driven gear ring 4036 is provided on the outer ring wall of the grinding ring 4032, meshing with the second gear 4035. A main shaft 4037 is rotatably mounted at the center of the disc 4031. One end of the main shaft 4037 extends into the mounting groove 4033 and is coaxially connected to the first gear 4034. The other end of the main shaft 4037 is connected to a drive shaft 402. Therefore, when the motor 401 drives the spindle 4037 to rotate, it can indirectly drive the grinding ring 4032 to rotate, thereby using the grinding ring 4032 to grind the inner wall of the steel pipe.

[0040] To maintain the stability of the disk 4031, in this embodiment, a protective sleeve 404 is fitted around the drive shaft 402. The protective sleeve 404 is a square tube. A stabilizing ring 405 is rotatably fitted around the drive shaft 402 via bearings. Both the upper and lower ends of the stabilizing ring 405 are connected to the inner wall of the protective sleeve 404 via springs 406. It should be noted that the spring 406 is a damping spring that can only extend and retract along its own axial direction. The two ends of the damping spring are connected to the stabilizing ring 405 and the inner wall of the protective sleeve 404, respectively. Therefore, the stabilizing ring 405 has a certain amount of extension and retraction along the height direction.

[0041] In addition, a displacement groove 4038 is formed on the surface of the disk 4031, such as Figure 6 As shown, the displacement groove 4038 is U-shaped, and a slider 407, also U-shaped, is vertically slidable inside the displacement groove 4038. The slider 407 is connected to the protective sleeve 404. A second linear drive assembly 408 is also provided on the support platform 301. The second linear drive assembly 408 is used to drive the protective sleeve 404 to move up and down relative to the support platform 301. In this embodiment, the second linear drive assembly 408 is a screw. The top end of the screw is rotatably connected to the protective sleeve 404, and the bottom end of the screw passes through the support platform 301 and is threaded to it. Therefore, by rotating the screw, the up and down movement of the protective sleeve 404 relative to the support platform 301 can be controlled.

[0042] Meanwhile, to improve the stability of the protective sleeve 404, multiple vertically distributed guide rods 409 are also provided on the bottom wall of the protective sleeve 404, such as... Figure 2 As shown, the guide rod 409 movably passes through the support platform 301 to improve the support strength of the protective sleeve 404. Furthermore, since the front end of the protective sleeve 404 is connected to the disk 4031 via the slider 407, in this embodiment, when the grinding assembly 403 is not in contact with the steel pipe, the drive shaft 402 is always located in the central position inside the protective sleeve 404 under the action of the spring 406. When the grinding assembly 403 abuts against the inner wall of the steel pipe, the second linear drive assembly 408 can drive the protective sleeve 404 to move relative to the drive shaft 402, thereby causing the slider 407 to shift within the displacement groove 4038.

[0043] In this embodiment, the grinding assembly 403 is first inserted into the steel pipe to be ground. Then, the height of the support platform 301 is controlled by the first linear drive assembly 303, causing the grinding ring 4032 to abut against the inner bottom wall of the steel pipe. Next, the protective sleeve 404 is controlled to move downward relative to the drive shaft 402 by the second linear drive assembly 408, thereby applying downward pressure to the grinding assembly 403 and ensuring full contact between the grinding ring 4032 and the inner bottom wall of the steel pipe. Then, the pipe support rotation mechanism 200 and the motor 401 are activated to control the steel pipe and the grinding ring 4032 to rotate in opposite directions. Specifically, the steel pipe rotates clockwise, and the grinding ring 4032 rotates counterclockwise.

[0044] When the grinding ring 4032 rotates to begin grinding, the slide block 300 is pushed closer to the steel pipe so that the grinding component 403 can penetrate deeper into the steel pipe. When the grinding component 403 moves from one end of the steel pipe to the other, the initial grinding is considered complete. To further improve the grinding effect, a second grinding is required. At this time, the support platform 301 is raised by the first linear drive component 303 so that the grinding ring 4032 abuts against the inner top wall of the steel pipe. Then, the protective sleeve 404 is driven to move upward relative to the drive shaft 402 by the second linear drive component 408 so that the grinding ring 4032 can fully contact the inner top wall of the steel pipe. After the adjustment is completed, the slide block 300 is gradually moved away from the steel pipe until the grinding component 403 is removed from the inside of the steel pipe, and the second grinding is completed.

[0045] In this embodiment, the reason for placing the grinding component 403 in contact with the inner top wall of the steel pipe during the secondary grinding is that some of the debris generated during the initial grinding will accumulate at the inner bottom of the steel pipe. Therefore, if the grinding ring 4032 is still in contact with the inner bottom wall of the steel pipe during the secondary grinding, the debris will inevitably affect the grinding effect. Furthermore, the debris moves with the rotation of the steel pipe, making it easy for it to fall onto the grinding component 403. Additionally, this embodiment implements secondary grinding primarily because the main function of the primary grinding is rust and dirt removal, while the secondary grinding is used for polishing, resulting in a more thorough grinding effect.

[0046] This embodiment also includes a dust collection mechanism 500, which includes a dust collection component and an exhaust fan 501. The dust collection component is mounted on the grinding component 403, and the exhaust fan 501 is mounted on the slide 300. The dust collection component is connected to the suction end of the exhaust fan 501 via a flexible hose 502. The dust collection component is used to generate negative pressure to absorb debris. It should be noted that the flexible hose 502 runs along the protective sleeve 404. Specifically, the flexible hose 502 and the protective sleeve 404 can be bound together with cable ties to prevent the flexible hose 502 from dragging inside the steel pipe and affecting the grinding process.

[0047] Specifically, the vacuuming assembly includes a vacuum hood 503, on which a displacement frame 504 is fixedly mounted. An arc-shaped guide rail 4039 is provided on the outer surface of the disc 4031, and the center of the arc-shaped guide rail 4039 coincides with the center of the disc 4031. The displacement frame 504 slides in conjunction with the arc-shaped guide rail 4039. An iron block 505 is also provided on the displacement frame 504. Electromagnets 506 for attracting the iron block 505 are provided on the surface of the disc 4031 and at both ends of the arc-shaped guide rail 4039. That is, when the two electromagnets 506 are alternately energized, the displacement frame 504 can be driven to slide back and forth along the arc-shaped guide rail 4039.

[0048] The curved guide rail 4039 has ends A and B, respectively. When the displacement frame 504 is at end A, the dust hood 503 is located at the lower right of the disc 4031, and the opening of the dust hood 503 faces left. Figure 6 As shown; when the displacement frame 504 is at end B, the dust hood 503 is located on the left side of the disc 4031, and the opening of the dust hood 503 faces upward. The opening end of the dust hood 503 is at approximately the same height as the central axis of the disc 4031. Figure 7 As shown.

[0049] It should be noted that, since the grinding ring 4032 rotates counterclockwise in this embodiment, when the grinding ring 4032 contacts the inner bottom wall of the steel pipe, the grinding debris will be generated from the bottom of the grinding ring 4032 and fly out to the right. At this time, the dust suction hood 503 is located at the lower right of the disc 4031, which helps to absorb the debris. When the grinding ring 4032 contacts the inner top wall of the steel pipe, the debris will be generated from the top of the grinding ring 4032 and fly out to the left. At this time, the dust suction hood 503 is located at the left side of the disc 4031, which also helps to absorb the debris.

[0050] It is worth mentioning that, due to the force of gravity, when the grinding ring 4032 comes into contact with the inner top wall of the steel pipe, the generated debris will fly out to the lower left along the grinding ring 4032. If the dust collection hood 503 is located to the upper left of the disc 4031 at this time, due to the gap between the dust collection hood 503 and the grinding ring 4032, some debris will fly out from the gap, resulting in poor debris collection. In this embodiment, when the displacement frame 504 is located at end B, the opening end of the dust collection hood 503 is at approximately the same height as the central axis of the disc 4031. Therefore, the debris flying out to the lower left along with the grinding ring 4032 can accurately fall into the dust collection hood 503, which helps in debris collection.

[0051] Additionally, the disc 4031 is equipped with a power supply 507 for powering the electromagnet 506. Two microswitches 508 are respectively located at the upper and lower ends of the displacement groove 4038, and each microswitch 508 is connected in series with one electromagnet 506. When the slider 407 abuts against the microswitch 508 at the bottom of the displacement groove 4038, the electromagnet 506 at end A of the arc-shaped guide rail 4039 is energized. When the slider 407 abuts against the microswitch 508 at the top of the displacement groove 4038, the electromagnet 506 at end B of the arc-shaped guide rail 4039 is energized. Specifically, when the protective sleeve 404 moves downward relative to the drive shaft 402, it abuts against the microswitch 508 at the bottom of the displacement groove 4038. At this time, the electromagnet 506 at end A of the arc-shaped guide rail 4039 is energized, and the dust cover 503 moves to the lower right position of the disc 4031. When the protective sleeve 404 moves upward relative to the drive shaft 402 and comes into contact with the micro switch 508 at the top of the displacement groove 4038, the electromagnet 506 located at the end of the arc-shaped guide rail 4039B is energized, and the dust cover 503 moves to the left side of the disk 4031.

[0052] Therefore, in this embodiment, during a single grinding operation, because the grinding component 403 is in full contact with the inner bottom wall of the steel pipe, the dust suction hood 503 can be automatically held at the lower right position of the disc 4031; when the grinding component 403 is in full contact with the inner top wall of the steel pipe, the dust suction hood 503 can be automatically held at the left side position of the disc 4031. No manual control is required, greatly improving the automation level of this device.

[0053] In other embodiments of this application, the dust hood 503 includes a base plate 5031. A first wall panel 5032 is provided on the side of the base plate 5031 near the disc 4031, and a second wall panel 5033 is hinged to the side of the base plate 5031 away from the disc 4031. Two fireproof cloths 5035 are provided between the first wall panel 5032 and the second wall panel 5033. A circular hole for connecting to a flexible hose 502 is also provided on the base plate 5031. The fireproof cloth 5035 is made of fiberglass, which has high-temperature resistance and can prevent high-temperature debris from burning the fireproof cloth 5035.

[0054] Meanwhile, an elastic element 5034 is provided between the second wall panel 5033 and the bottom plate 5031. When the displacement frame 504 is located at end A of the arc-shaped guide rail 4039 and the grinding ring 4032 abuts against the inner bottom wall of the steel pipe, the opening width of the dust suction hood 503 is smaller than the width of the bottom plate 5031. When the displacement frame 504 is located at end B of the arc-shaped guide rail 4039 and the grinding ring 4032 abuts against the inner top wall of the steel pipe, the opening end of the dust suction hood 503 is at a height equivalent to the central axis of the disc 4031, and the opening width of the dust suction hood 503 is greater than the width of the bottom plate 5031.

[0055] Specifically, when the displacement frame 504 is located at end A of the arc-shaped guide rail 4039, and the grinding ring 4032 abuts against the inner bottom wall of the steel pipe, the elastic element 5034 is fully compressed due to the contact between the second wall plate 5033 and the inner bottom wall of the steel pipe. At this time, the opening width of the dust collection hood 503 is narrower, which increases the negative pressure suction at the opening, helping to fully absorb debris. When the displacement frame 504 is located at end B of the arc-shaped guide rail 4039, and the grinding ring 4032 abuts against the inner top wall of the steel pipe, the second wall plate 5033 loses external obstruction. Therefore, under the elastic force of the elastic element 5034, the second wall plate 5033 can be fully expanded. At this time, the fireproof cloth 5035 is taut, which expands the opening area to accommodate the debris distribution under these conditions, helping more debris fall into the dust collection hood 503.

[0056] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
