Description
Technical Field
[0001] The utility model relates to the technical field of pipeline rust removal, in particular to equipment for removing rust from the outer surface of a construction pipeline. Background Art
[0002] During the storage process, pipes used in urban construction will become rusty due to moisture. In order to avoid further corrosion and extend their service life, they need to be derusted before use.
[0003] In order to reduce the cost of polishing pipes or reduce the area occupied by polishing equipment, some existing manufacturing companies usually choose manual polishing. The rust on the outer wall of the pipe is polished by manual handheld polishing equipment. Generally, the pipe is first installed horizontally on a pipe turning machine. The pipe turning machine includes a clamping mechanism for clamping the pipe. The clamping mechanism is connected to a drive motor so that the pipe can be rotated before polishing. However, for some small-diameter pipes with less severe rust, it is not easy to control the polishing force when polishing with handheld polishing equipment, resulting in uneven thickness of the polished surface, which can easily pierce thin-walled small-diameter pipes; and the polishing disc is a consumable item, so it is necessary to frequently stop the polishing operation and replace the polishing disc. Utility Model Content
[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a rust removal device for the outer surface of a construction pipeline.
[0005] The technical solution of this utility model is as follows:
[0006] A construction pipeline outer surface rust removal device comprises a pipe drilling machine on which the pipeline is placed horizontally, the pipeline is rotatably arranged on the pipe drilling machine, and also comprises a movable frame located outside the pipeline and lockable, and a grinding piece located on one side of the outer surface of the pipeline is arranged on the movable frame;
[0007] The grinding piece is connected to the mobile frame through a telescopic device, and the grinding surface of the grinding piece can reach the outer surface of the pipeline;
[0008] The grinding piece includes a grinding plate and at least one grinding block. The grinding block is arranged on one side of the grinding plate close to the outer surface of the pipe, and its length direction is parallel to the axial direction of the pipe drilling machine. The grinding block is detachably connected to the grinding plate.
[0009] The pipe to be derusted is connected to the pipe drilling machine, which is a prior art. The pipe can be horizontally arranged on the pipe drilling machine and can rotate under the drive of the pipe drilling machine. The side of the grinding plate close to the outer surface of the pipe is the grinding surface. The rust on the outer side of the pipe is polished by the grinding piece. The grinding surface of the grinding piece can contact or move away from the outer surface of the pipe under the drive of the telescopic device. In order to reduce the number of times the grinding block is replaced, the number of grinding blocks can be set to be multiple. After a grinding block is worn out and cannot be used, the position of the movable frame can be adjusted and the remaining grinding blocks can be used for grinding.
[0010] Regarding the setting position of the grinding plate, the grinding plate is set horizontally, and its length direction is perpendicular to the axis of the pipe drilling machine. The grinding plate can be set just above or just below the pipe. The grinding plate is set just above the pipe to facilitate the collection of grinding waste.
[0011] In order to cooperate with the telescopic device to make the grinding surface of the grinding plate contact and grind with the outer surface of the pipe, both sides of the grinding plate are set to slide with the movable frame, and the sliding direction is vertical, which can improve the stability of the grinding plate when moving and avoid shaking during grinding.
[0012] There are multiple grinding blocks mentioned above. Specifically, the grinding plate is provided with multiple groups of grinding blocks along its length direction. A single grinding block group includes two symmetrically arranged grinding blocks, that is, there are multiple groups of two symmetrically arranged grinding blocks. The two symmetrically arranged grinding blocks can grind the rust on the outer surface of the pipe at the same time, thereby improving the grinding speed. After one group of grinding blocks is worn out, it can be directly replaced by another group of grinding blocks without stopping the machine to replace the grinding parts.
[0013] Regarding the specific structure of the grinding block, the cross-section of the grinding block is an arc-shaped surface, which is conducive to the coordinated use of two symmetrical grinding blocks.
[0014] In order to be able to remove rust from pipes of different diameters, the radius of the grinding blocks of the multiple groups of grinding blocks increases successively along the length direction of the grinding plate. Two grinding blocks with smaller radius and symmetrical arrangement can remove rust from the outer surface of a small diameter pipe, and the spacing between the two grinding blocks can be set to a smaller spacing; similarly, a grinding block with a larger radius can remove rust from a pipe with a slightly larger diameter.
[0015] The process of grinding the outer surface of the pipe needs to be from coarse grinding to fine grinding. The abrasive grits of the grinding blocks of the multiple grinding block groups decrease in sequence. The higher the grit of the grinding block, the higher the grinding fineness. First, coarse grinding is performed using a coarse grinding block with a small abrasive grit, and then fine grinding is performed using a fine grinding block with a large abrasive grit.
[0016] In order to facilitate the rapid replacement of the grinding block, the grinding block is plugged into the side of the grinding plate close to the pipe along the direction perpendicular to the length of the grinding plate.
[0017] The beneficial effects of the utility model are:
[0018] The grinding plate is arranged on the outer side of the pipe, and the grinding surface of the grinding plate can be moved to the outer surface of the pipe to contact it through the telescopic device. The telescopic device can be adjusted to any length and can be locked. Compared with manual grinding, it is easier to control the grinding thickness and uniformity of the outer surface of the pipe;
[0019] There are multiple grinding blocks on the grinding plate. When one grinding block is worn out and cannot be used, the telescopic device is controlled to drive the grinding plate away from the outer surface of the pipeline, and the movable and lockable moving frame is adjusted to move another adjacent grinding block to the top of the pipeline. The telescopic device is controlled to use a new grinding block to grind and remove rust from the pipeline, eliminating the step of replacing the grinding block, and can be operated without stopping the machine, thereby improving the grinding efficiency.
[0020] By setting multiple groups of grinding blocks, two symmetrically arranged grinding blocks can be used to grind the outer surface of the pipe at the same time, thereby improving the grinding efficiency;
[0021] A plurality of grinding block groups are provided, and the abrasive grain sizes of the grinding blocks of adjacent grinding block groups are all different, so as to achieve coarse grinding and fine grinding of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

The grinding piece is connected to the movable frame 1 through a telescopic device 2, and the grinding surface of the grinding piece can reach the outer surface of the pipe.
[0030] See also Figure 2 and Figure 3As shown, in order to cooperate with the telescopic device 2 to bring the polishing surface of the polishing plate 3 into contact with the outer surface of the pipe for polishing, sliding bars 31 are provided on both sides of the polishing plate 3 along the length direction, and a sliding groove 11 cooperating with the sliding bar 31 is provided on the frame body of the movable frame 1. The sliding bar 31 slides in the sliding groove 11 to realize the sliding connection between the polishing plate 3 and the movable frame 1, and the sliding direction is the vertical direction, which can improve the stability of the polishing plate 3 during movement and avoid shaking during polishing.
[0031] The grinding piece includes a grinding plate 3 and at least one grinding block 4. The grinding block 4 is arranged on the side of the grinding plate 3 close to the outer surface of the pipe, and its length direction is parallel to the axial direction of the pipe drilling machine 5. The grinding block 4 is detachably connected to the grinding plate 3. The grinding surface is the side of the grinding plate 3 and the grinding block 4 close to the outer surface of the pipe. In order to facilitate the rapid replacement of the grinding block 4, the grinding block 4 is plugged into the side of the grinding plate 3 close to the pipe 6 in a direction perpendicular to the length of the grinding plate 3.
[0032] The above-mentioned pipe 6 to be derusted is connected to the pipe drilling machine 5, which is a prior art. The pipe drilling machine 5 includes a clamping mechanism 51 for clamping the pipe 6, and the clamping mechanism 51 is driven to rotate by a motor 52. A support seat 53 is provided at one end of the pipe 6 away from the clamping mechanism 51, and the support seat 53 is rotatably connected to the support seat 53, so that the pipe 6 can rotate. The pipe 6 can be arranged horizontally on the pipe drilling machine 5, and the rust on the outer side of the pipe is polished by a polishing piece. The polishing surface of the polishing piece can contact or stay away from the outer surface of the pipe under the drive of the telescopic device 2. The telescopic device 2 is a prior art and can drive the polishing plate 3 to move any distance and lock it. When the pipe 6 is polished, the telescopic device 2 is in a locked state.
[0033] Regarding the setting position of the grinding plate 3, the grinding plate 3 is set horizontally, and its length direction is perpendicular to the axis of the pipe drilling machine 5. The grinding plate 3 can be set just above or just below the pipe 6. In this embodiment, the grinding plate 3 is set just above the pipe 6, which is convenient for collecting grinding waste and pressing the grinding plate 3 by the telescopic device 2, so as to control the grinding thickness.
[0034] See also Figure 1 and Figure 4 As shown, the present embodiment has multiple grinding blocks 4, specifically, the grinding plate 3 is provided with multiple groups of grinding blocks along its length direction, and a single grinding block group includes two symmetrically arranged grinding blocks 4, that is, two symmetrically arranged grinding blocks 4 are provided with multiple groups, and the two symmetrically arranged grinding blocks 4 can grind the rust on the outer surface of the pipeline at the same time, thereby improving the grinding speed, and after one group of grinding blocks is worn, the other group of grinding blocks can be directly replaced without stopping the machine to replace the grinding parts. In order to facilitate the two symmetrically arranged grinding blocks 4 to grind the pipeline 6 at the same time, the cross section of the grinding block 4 is an arc surface.
[0035] As another arrangement of the grinding blocks 4, the radius of the grinding blocks 4 of the multiple groups of grinding blocks increases successively along the length direction of the grinding plate 3, so that the pipes 6 of different diameters can be derusted. Two grinding blocks 4 with smaller radius and symmetrical arrangement can derust the outer surface of the small diameter pipe, and the spacing between the two grinding blocks 4 can be set to a smaller spacing; similarly, the grinding block 4 with larger radius can derust the pipe 6 with slightly larger diameter.
[0036] The existing pipeline outer surface grinding requires coarse grinding and fine grinding. The grinding process requires continuous replacement of grinding sheets of different coarseness and fineness. In order to reduce the steps of replacing grinding sheets, the present embodiment sets multiple groups of grinding block groups, and the mesh numbers of the grinding blocks 4 of the abrasive grains decrease in sequence. The higher the mesh number of the abrasive grains of the grinding blocks 4, the higher the grinding fineness. First, rough grinding is performed by the coarse grinding grinding blocks 4 with small abrasive grains, and the telescopic device 2 is controlled to separate the grinding plate 3 from the pipeline 6. The position of the movable frame 1 is adjusted to a suitable group of grinding blocks, and the telescopic device 2 is controlled to push the grinding surface against the outer surface of the pipeline. Fine grinding is performed by the fine grinding grinding blocks 4 with large abrasive grains. In the present embodiment, a group of grinding blocks 4 with a smaller radius can be set to a grinding block 4 with a larger mesh number for fine grinding; a group of grinding blocks 4 with a larger radius can be set to a grinding block 4 with a smaller mesh number for coarse grinding.
