Description

Technical Field

[0001] The present application relates to the technical field of rust removal equipment, and specifically to a rust removal equipment for steel pipes. Background Art

[0002] Steel pipes are very easy to rust when placed outdoors or in a humid room for a long time, which not only affects the appearance quality, but also affects the normal progress of processes such as painting and bonding. If not handled in time, it will cause the material to be scrapped. Therefore, it is necessary to use rust removal equipment to remove rust from the pipes in time;

[0003] For example, the patent with publication number CN218427556U specifically discloses a surface rust removal device for pipe processing, which inserts the polished pipe into the position between the first friction pad and the second friction pad, and rotates the pipe body so that the first friction pad and the second friction pad respectively wipe off the rust powder attached to the inner and outer walls of the pipe and make the powder fall into the inside of the installation cylinder, and then removes the insert from the hole on the surface of the bottom plate to facilitate cleaning of the rust powder in the installation cylinder.

[0004] In the above patent, the device is provided with two sets of friction pads so that the device can grind the inner wall and the outer wall of the pipe at the same time, thereby saving the time for rust removal. However, since the device only grinds the steel pipe through the friction pads during rust removal, the rust on the outside of the steel pipe may splash around during grinding, which may lead to the deterioration of the working environment and increase the cleaning cost. The splashed rust may also fly into other devices and may damage the devices. Therefore, it is necessary to provide a steel pipe rust removal device with a collection device to solve the above problems.

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] Embodiment 1

[0037] like Figure 1-Figure 4 , Figure 7 As shown, the present application provides a steel pipe rust removal device, including a rust removal component 1, the rust removal component 1 is used to treat the rust on the outside of the steel pipe, the rust removal component 1 includes a mounting frame 11, and the mounting frame 11 is arranged in a steel pipe processing plant;

[0038] At the same time, two groups of feeding parts 2 are arranged in the mounting frame 11, and the feeding part 2 includes two groups of cross beams 21, and the two groups of cross beams 21 are fixedly installed on both sides of the bottom of the mounting frame 11, and a bottom plate 22 is fixedly installed on the cross beams 21, and a first cylinder 23 is fixedly installed at the bottom of the bottom plate 22, and the output end of the first cylinder 23 passes through the bottom plate 22 and is fixedly installed with a supporting plate 24; in some embodiments, the top of the supporting plate 24 is arranged in an arc shape to facilitate lifting the steel pipe; in some embodiments, a plurality of supporting roller groups can also be arranged on the supporting plate 24, and each supporting roller group includes two supporting rollers rotatably connected to the supporting plate 24, and the steel pipe is supported between the two supporting rollers, so as to better support the steel pipe;

[0039] At the same time, a clamping part 3 is arranged on the top of the mounting frame 11, and the clamping part 3 includes a slide seat sliding on the top of the mounting frame 11, a sliding mechanism and a rotating motor 31 fixedly installed on the slide seat, the sliding mechanism is installed on the mounting frame 11, and the sliding mechanism is connected to the slide seat to drive the slide seat to slide, and a first disc 32 is fixedly installed on the output end of the rotating motor 31, and a groove is arranged inside the first disc 32, and the size of the groove is adapted to the diameter of the steel pipe, and at the same time, a second cylinder 33 is fixedly installed on the other side of the top of the mounting frame 11, and a second disc 34 is rotatably installed on the output end of the second cylinder 33, and the second disc 34 and the first disc 32 have the same structure, and the second cylinder 33 is used to push the second disc 34 to move, so that the second disc 34 pushes the steel pipe to move, so that the steel pipe is clamped and installed between the first disc 32 and the second disc 34;

[0040] When loading is required, the steel pipe to be polished is first placed manually on the top of the two groups of support plates 24, and then the first cylinder 23 is started, so that the two groups of first cylinders 23 drive the steel pipe to move toward the top of the mounting frame 11. When the steel pipe reaches the clamping position of the clamping part 3, the sliding mechanism can be started to drive the rotating motor 31 and the first disc 32 thereon to move toward the direction of the steel pipe, and the second cylinder 33 is started to drive the second disc 34 to move toward the direction of the steel pipe, so that one end of the pipe is stuck in the groove in the second disc 34, and the end of the steel pipe away from the second disc 34 enters the groove of the first disc 32. At this time, the steel pipe is completely clamped and fixed by the first disc 32 and the second disc 34, and the steel pipe is suitable for rotating under the drive of the rotating motor 31.

[0041] In this embodiment, the sliding mechanism may be in the form of a cylinder or a motor and a screw-nut pair.

[0042] like Figure 2-Figure 6 As shown, a grinding part 4 is provided on one side of the clamping part 3, and the grinding part 4 includes two sets of tracks 41, and the tracks 41 are arranged parallel to the steel pipe. At least two sets of trolleys 42 are installed on the tracks 41, and the trolleys 42 are suitable for reciprocating on the tracks 41. In this embodiment, the trolleys 42 are driven by a motor, and the rotation speed and direction of the motor can be manually controlled to achieve precise movement of the trolleys 42 on the tracks 41;

[0043] Meanwhile, a grinder 43 is installed on the trolley 42. The grinder 43 includes a housing 44, which is fixedly installed on the top of the trolley 42. A driving wheel 45 and two sets of driven wheels 46 are rotatably installed in the housing 44. The driving wheel 45 and the two sets of driven wheels 46 are arranged in a triangle in the housing 44. A motor (not shown in the figure) is fixedly installed on one side of the driving wheel 45. The motor is used to drive the driving wheel 45 to rotate, and patterns are provided on the outer sides of the driving wheel 45 and the two sets of driven wheels 46. The patterns are used to increase friction.

[0044] At the same time, a grinding belt 47 is provided in the grinder 43, and the grinding belt 47 is sleeved on the outer sides of the driving wheel 45 and the two sets of driven wheels 46. When the motor drives the driving wheel 45 to rotate, the grinding belt 47 will move in a circle driven by the driving wheel 45, and one side of the grinding belt 47 facing the steel pipe is tilted downward, so that when the grinder 43 is grinding the steel pipe, the rust detached from the steel pipe will splash toward the bottom of the grinder 43.

[0045] When grinding is required, the grinder 43 is first turned on so that the grinding belt 47 on the grinder 43 contacts the steel pipe. At the same time, the trolley 42 moves slowly on the track 41 so that the grinder 43 grinds a certain area of ​​the steel pipe. When the trolley 42 moves from one side of the track 41 to the other side, the rust in the grinding area will be polished away. At this time, the grinder 43 will be temporarily turned off and the rotating motor 31 will be started to rotate the steel pipe by a certain angle, so that the unpolished part of the steel pipe enters the grinding range of the grinder 43, and the above grinding steps are repeated until the outer side of the steel pipe is fully and evenly polished, thereby ensuring the stability of the rust removal quality.

[0046] In order to enable the grinding part 4 to collect rust in time when grinding the steel pipe, improvements are made on the mounting frame 11, specifically:

[0047] like Figure 1 , Figure 6 As shown, a plurality of nozzles 12 are arranged on one side of the mounting frame 11 close to the clamping portion 3, and the bottom of the nozzle 12 is connected to the air outlet of the external fan. The nozzle 12 is arranged toward the steel pipe to clean and blow off the debris remaining on the surface of the steel pipe, and at the same time, the steel pipe can be cooled by blowing air to prevent the steel pipe from overheating and deformation;

[0048] A collecting mechanism 5 is also provided at the bottom of the mounting frame 11. The collecting mechanism 5 includes a collecting tank 51 installed at one side of the bottom of the mounting frame 11. The length of the collecting tank 51 is greater than the length of the steel pipe, and a discharge port 52 is provided on one side of the collecting tank 51. A discharge pipe 521 is fixedly installed at the bottom of the discharge port 52. The discharge pipe 521 is connected to an external recovery device and is used to recover iron scraps peeled off the steel pipe.

[0049] At the same time, a pusher trolley 53 is provided on the side of the collecting trough 51 away from the discharge port 52. The pusher trolley 53 is also suitable for being driven by a motor. A bucket 54 is fixedly installed on the top of the pusher trolley 53. The size of the bucket 54 is adapted to the size of the collecting trough 51, and the top of the bucket 54 is arranged in an arc shape, so that rust falling on the top of the bucket 54 can directly slide into the collecting trough 51.

[0050] When the steel pipe is being polished, since one side of the polishing belt 47 is tilted downward, the iron filings detached from the steel pipe during polishing will directly fall into the collecting tank 51. At the same time, through the arrangement of multiple groups of nozzles 12, the remaining rust will also enter the collecting tank 51. When the polishing is completed, the bucket 54 is driven to move in the collecting tank 51 by starting the pusher 53. At this time, the materials accumulated in the collecting tank 51 will be driven by the bucket 54 and pushed into the discharge port 52 for recycling.

[0051] When a group of steel pipes is processed, the sliding mechanism and the second cylinder 33 are controlled to retreat, so that the polished steel pipes lose the clamping of the first disc 32 and the second disc 34 and are lifted up by the support plate 24 again. At this time, the first cylinder 23 is controlled to retreat, so that the staff can quickly remove the steel pipes and put in new steel pipes to be processed, and then repeat the above polishing process.

[0052] In summary, the device provides the clamping part 3 and the grinding part 4 so that the exterior of the steel pipe can be uniformly ground in all aspects. At the same time, by providing the collecting mechanism 5, the rust generated during grinding can be collected and quickly processed without splashing everywhere, thereby increasing the practicability of the equipment.

[0053] Embodiment 2

[0054] The steel pipe rust removal equipment of this embodiment is basically the same as that of the first embodiment, except that, in order to adapt to the rust removal of steel pipes of different specifications, the first disc 32 and the second disc 34 are not provided with grooves, but protruding expansion shafts are provided on the opposite sides of the first disc 32 and the second disc 34, and the expansion shaft is extended into the inner hole of the steel pipe, and then the expansion shaft is actuated to tighten the inner diameter of the steel pipe, thereby achieving effective clamping and fixation of the steel pipe and subsequent rotation of the steel pipe; after the rust removal is completed, the expansion shaft is disengaged from the inner wall of the steel pipe by actuation, and then the sliding mechanism and the second cylinder 33 are controlled to retreat.

[0055] Embodiment 3

[0056] The steel pipe rust removal equipment of this embodiment is basically the same as that of the first embodiment, except that in order to apply a rust preventive on the outer wall of the steel pipe, a rust preventive spraying device is also included, which includes a bracket arranged on the trolley 42, an arc-shaped pipe fitting installed on the bracket and located above the steel pipe supported on the clamping portion 3, and a plurality of rust preventive spray heads connected to and communicated with the arc-shaped pipe fitting. The arc-shaped pipe fitting is externally connected to a spray pump, and a telescopic mechanism is also provided between the grinder 43 and the trolley 42. The telescopic mechanism is suitable for telescopic grinding machine 43. During rust removal and grinding, the telescopic mechanism extends the grinder 43 forward so that the grinding belt 47 contacts the steel pipe. After grinding, the telescopic mechanism drives the grinder 43 to return to its original position. After rust removal, the spray pump can be started, and the steel pipe can be driven to rotate by the rotating motor 31, and the trolley 42 is moved at the same time, so that the rust preventive is evenly sprayed on the outer wall of the steel pipe.

[0057] In this embodiment, the telescopic mechanism may be a piston cylinder, and the grinder 43 is mounted on the piston rod of the piston cylinder. Of course, other existing structures may also be used.

[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
