Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to a stainless steel pipe surface grinding device for communication tower processing. Background Art

[0002] Communication towers, also called signal transmission towers or signal towers, are mainly used to provide support for signal transmission antennas, erect antennas at high places, increase signal coverage and strength, and ensure the normal operation of wireless communication systems. They are widely used in mobile, Unicom, telecommunications and other communication departments.

[0003] At present, steel pipes are widely used as supporting components in the manufacturing process of communication towers to bear the weight of the communication tower, the weight of antennas and other equipment, as well as external forces such as wind loads and earthquake loads. Before the steel pipes are put into manufacturing, they need to undergo inner and outer wall grinding to remove rust and stains on the pipe body, and spray a layer of corrosion-resistant coating to enhance the corrosion resistance of the communication tower and extend the service life of the communication tower. Nowadays, the inner wall grinding of the steel pipe is usually done by extending the grinding wheel into the interior of the steel pipe, so that the grinding wheel and the inner wall of the steel pipe are in contact and slowly move forward along the axis of the steel pipe, while keeping the steel pipe itself rotating slowly to evenly grind various positions of the inner wall of the steel pipe.

[0004] However, since a lot of debris and powder will be generated during the grinding process, if these debris and powder are not cleaned up in the steel pipe, they will easily fly out and pollute the external environment during the subsequent installation and transportation. At the same time, since the steel pipe itself keeps rotating at a constant speed during the grinding process, the debris and powder will move with the rotation of the steel pipe, so it is very easy to fall onto the grinding equipment, causing the grinding equipment to be contaminated, which will cause trouble for the subsequent cleaning work. In view of this, we proposed a stainless steel pipe surface grinding device for communication tower processing to solve the above disadvantages. Summary of the invention

DETAILED DESCRIPTION

[0035] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 - Fig. 9A stainless steel pipe surface grinding device for communication tower processing includes a base 100 and a pipe support rotating mechanism 200. The pipe support rotating mechanism 200 is arranged on one side of the top surface of the base 100, and is used to support the pipe to be placed flat and control the pipe to rotate around its own central axis; specifically, the pipe support rotating mechanism 200 has at least two, and the pipe support rotating mechanism 200 includes two rollers that are relatively distributed, and also has a motor that can drive the rollers to rotate. When the steel pipe is placed flat on the two rollers, as the rollers rotate, the steel pipe can be driven to rotate at a uniform speed.

[0037] This embodiment also includes a slide 300 and a grinding mechanism 400, wherein the slide 300 is slidably arranged on the top surface of the base 100, and a support platform 301 capable of vertical lifting and lowering is also provided on the top surface of the slide 300; support columns 302 distributed vertically are provided on both the front and rear sides of the top surface of the slide 300, and the support platform 301 and the support columns 302 are slidably matched, and a first linear drive component 303 is also provided on the top surface of the slide 300, and the first linear drive component 303 is used to push the support platform 301 to slide up and down. In this embodiment, the first linear drive component 303 adopts a cylinder or a hydraulic cylinder, whose cylinder body is fixedly connected to the slide 300, and whose movable end is connected to the bottom surface of the support platform 301.

[0038] Furthermore, the grinding mechanism 400 includes a motor 401, a drive shaft 402 and a grinding assembly 403, wherein the motor 401 is fixedly mounted on the top surface of the support platform 301 through a motor seat, and the output shaft of the motor 401 is connected to the grinding assembly 403 through the drive shaft 402, that is, the two ends of the drive shaft 402 are respectively connected to the output shaft of the motor 401 and the grinding assembly 403.

[0039] Specifically, the grinding assembly 403 includes a disc 4031 and a grinding ring 4032 rotatably mounted on the outside of the disc 4031, wherein the grinding ring 4032 is made of silicon carbide, and the disc 4031 is made of aluminum alloy. A mounting groove 4033 is provided on the outer ring wall of the disc 4031, and a first gear 4034 and a second gear 4035 are rotatably mounted in the mounting groove 4033, and the first gear 4034 and the second gear 4035 are meshed with each other. A driven gear ring 4036 is provided on the outer ring wall of the grinding ring 4032, and the second gear 4035 is meshed with the driven gear ring 4036. 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, and the other end of the main shaft 4037 is connected to the drive shaft 402. Therefore, when the motor 401 drives the main shaft 4037 to rotate, the grinding ring 4032 can be indirectly driven to rotate, so that the inner wall of the steel pipe is ground by the grinding ring 4032.

[0040] In order to maintain the stability of the disc 4031, in this embodiment, a protective sleeve 404 is sleeved on the outside of the driving shaft 402, and the protective sleeve 404 is a square tube. A stabilizing ring 405 is sleeved on the outside of the driving shaft 402 through a bearing rotation, and the upper and lower ends of the stabilizing ring 405 are connected to the inner wall of the protective sleeve 404 through a spring 406. It should be noted that the spring 406 is a damping spring that can only be extended and retracted along its own axial direction, and the two ends of the damping spring are respectively connected to the stabilizing ring 405 and the inner wall of the protective sleeve 404, so the stabilizing ring 405 has a certain amount of extension and retraction along the height direction.

[0041] In addition, a displacement groove 4038 is provided on the surface of the disk 4031. Figure 6 As shown, the displacement groove 4038 is in the shape of a Chinese character “Yu”, and a slider 407 is provided inside the displacement groove 4038 for vertical sliding, and the slider 407 is also in the shape of a Chinese character “Yu”, and the slider 407 is connected to the protective sleeve 404; a second linear drive component 408 is also provided on the support platform 301, and the second linear drive component 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 component 408 adopts a screw, the top of the screw is rotatably connected to the protective sleeve 404, and the bottom of the screw passes through the support platform 301 and is threadedly connected thereto, so by rotating the screw, the protective sleeve 404 can be controlled to move up and down relative to the support platform 301.

[0042] At the same time, in order to improve the stability of the protective sleeve 404, a plurality of guide rods 409 distributed vertically are provided on the bottom wall of the protective sleeve 404. Figure 2 As shown, the guide rod 409 movably penetrates the support platform 301, and is used to improve the support strength of the protective sleeve 404. In addition, since the front end of the protective sleeve 404 is connected to the disc 4031 through the slider 407, in this embodiment, when the grinding assembly 403 is not in contact with the steel pipe, under the action of the spring 406, the drive shaft 402 is always located in the center of the protective sleeve 404. 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, so that the slider 407 is displaced inside the displacement groove 4038.

[0043] In the specific implementation process of this embodiment, the grinding assembly 403 is first extended into the steel pipe to be polished, and then the height of the support platform 301 is controlled by the first linear drive assembly 303, so that the grinding ring 4032 is in contact with the inner bottom wall of the steel pipe, and then the protective sleeve 404 is controlled to move downward relative to the drive shaft 402 by the second linear drive assembly 408, so as to apply downward pressure to the grinding assembly 403, so that the grinding ring 4032 is fully in contact with the inner bottom wall of the steel pipe. Then the pipeline support rotation mechanism 200 and the motor 401 are started 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 and starts grinding, the slide 300 is pushed gradually closer to the steel pipe, so that the grinding component 403 continues to penetrate into the steel pipe; when the grinding component 403 moves from one end of the steel pipe to the other end, the initial grinding is considered to be completed. In order to further improve the grinding effect, secondary grinding is required. At this time, the first linear drive component 303 is used to control the support platform 301 to rise, so that the grinding ring 4032 and the inner top wall of the steel pipe are in contact, and then the second linear drive component 408 is used to drive the protective sleeve 404 to move upward relative to the drive shaft 402, so that the grinding ring 4032 is fully in contact with the inner top wall of the steel pipe; after the adjustment is completed, the slide 300 is controlled to gradually move away from the steel pipe until the grinding component 403 moves out of the steel pipe, and the secondary grinding is completed.

[0045] The reason why the grinding assembly 403 is in contact with the inner top wall of the steel pipe during the secondary grinding in this embodiment is that during the initial grinding, some debris generated will gather on 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. At the same time, the debris moves with the rotation of the steel pipe, which can easily cause the debris to fall onto the grinding assembly 403. At the same time, the secondary grinding in this embodiment is mainly because the main function of the primary grinding is to remove rust and dirt, and the secondary grinding is used for polishing, so that the grinding effect is more thorough.

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

[0047] Specifically, the dust collection assembly includes a dust collection hood 503, on which a displacement frame 504 is fixedly provided, and an arc guide rail 4039 is provided on the outer surface of the disk 4031, and the center of the circle corresponding to the arc guide rail 4039 coincides with the center of the circle of the disk 4031, and the displacement frame 504 slides with the arc guide rail 4039; an iron block 505 is also provided on the displacement frame 504, and electromagnets 506 for attracting the iron block 505 are provided on the surface of the disk 4031 and at both ends of the arc 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 guide rail 4039.

[0048] The two ends of the arc guide rail 4039 are end A and end B respectively. When the displacement frame 504 is located at end A, the dust hood 503 is located at the lower right position of the disc 4031, and the opening of the dust hood 503 faces left. Figure 6 When the displacement frame 504 is located at the B end, the dust cover 503 is located at the left side of the disk 4031, and the opening of the dust cover 503 faces upward, and the opening end of the dust cover 503 is at a height equivalent to the central axis of the disk 4031, as shown in FIG. Figure 7 shown.

[0049] It should be noted that, since the grinding ring 4032 in this embodiment rotates counterclockwise, when the grinding ring 4032 contacts the inner bottom wall of the steel pipe, the debris generated by grinding will be generated from the bottom of the grinding ring 4032 and fly out to the right, and at this time, the dust cover 503 is located at the lower right position of the disc 4031, which is helpful 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, and at this time, the dust cover 503 is located at the left position of the disc 4031, which is also conducive to absorbing the debris.

[0050] It is worth mentioning that, due to the effect of gravity on the debris itself, when the grinding circle 4032 abuts against the inner top wall of the steel pipe, the generated debris will fly out to the lower left along the grinding circle 4032. At this time, if the dust cover 503 is located at the upper left of the disc 4031, due to the gap between the dust cover 503 and the grinding circle 4032, some debris will fly out from the gap between the dust cover 503 and the grinding circle 4032, resulting in poor debris collection effect. In this embodiment, when the displacement frame 504 is located at the B end, the opening end of the dust cover 503 is at the same height as the central axis of the disc 4031, and the debris flying to the lower left along with the grinding circle 4032 can accurately fall into the dust cover 503, which is conducive to the collection of debris.

[0051] In addition, a power supply 507 for supplying power to the electromagnet 506 is provided on the disk 4031, and two micro switches 508 are respectively provided at the upper and lower ends of the displacement slot 4038, and the two micro switches 508 are respectively arranged in series with the two electromagnets 506; when the slider 407 abuts against the micro switch 508 at the bottom of the displacement slot 4038, the electromagnet 506 at the A end of the arc guide 4039 is energized; when the slider 407 abuts against the micro switch 508 at the top of the displacement slot 4038, the electromagnet 506 at the B end of the arc guide 4039 is energized. Specifically, when the protective sleeve 404 moves downward relative to the driving shaft 402, it can abut against the micro switch 508 at the bottom of the displacement slot 4038, and at this time, the electromagnet 506 at the A end of the arc guide 4039 is energized, and the dust cover 503 moves to the lower right position of the disk 4031. When the protective sleeve 404 moves upward relative to the driving shaft 402 and abuts against the micro switch 508 at the top of the displacement slot 4038 , the electromagnet 506 located at the end of the arc guide rail 4039B is energized, and the dust cover 503 moves to the left side of the disc 4031 .

[0052] Therefore, in the specific implementation process of this embodiment, during one grinding, since the grinding assembly 403 is in full contact with the inner bottom wall of the steel pipe, the dust hood 503 can be automatically kept at the lower right position of the disc 4031; when the grinding assembly 403 is in full contact with the inner top wall of the steel pipe, the dust hood 503 can be automatically kept at the left position of the disc 4031. No manual control is required, which greatly improves the automation degree of the device.

[0053] In some other embodiments of the present application, the dust cover 503 includes a bottom plate 5031, a first wall plate 5032 is provided on the side of the bottom plate 5031 close to the disc 4031, a second wall plate 5033 is hingedly provided on the side of the bottom plate 5031 away from the disc 4031, two fireproof cloths 5035 are provided between the first wall plate 5032 and the second wall plate 5033, and a round hole connected to the hose 502 is also provided on the bottom plate 5031. The fireproof cloth 5035 is made of glass fiber, which has high temperature resistance and can prevent high temperature debris from scalding the fireproof cloth 5035.

[0054] At the same time, an elastic member 5034 is provided between the second wall plate 5033 and the bottom plate 5031. When the displacement frame 504 is located at the A end of the arc guide rail 4039 and the grinding ring 4032 abuts against the inner bottom wall of the steel pipe, the opening width of the dust hood 503 is smaller than the width of the bottom plate 5031; when the displacement frame 504 is located at the B end of the arc guide rail 4039 and the grinding ring 4032 abuts against the inner top wall of the steel pipe, the opening end of the dust hood 503 is at the same height as the central axis of the disk 4031, and the opening width of the dust hood 503 is greater than the width of the bottom plate 5031.

[0055] Specifically, when the displacement rack 504 is located at the A end of the arc-shaped guide rail 4039 and the grinding ring 4032 abuts against the inner bottom wall of the steel pipe, the second wall plate 5033 abuts against the inner bottom wall of the steel pipe, so that the elastic member 5034 is in a fully compressed state. At this time, the opening width of the dust hood 503 is narrow, which serves to increase the negative pressure attraction at the opening and help to fully absorb debris. When the displacement rack 504 is located at the B end 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 the external force resistance, so under the elastic force of the elastic member 5034, the second wall plate 5033 can be fully unfolded, and the fireproof cloth 5035 is in a straight state, which serves to expand the opening area to adapt to the distribution of debris in this state, and help more debris fall into the dust hood 503.

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

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
