Description

Technical Field

[0001] This utility model relates to the field of pipe scraper technology, specifically a mechanical rotary scraper for PE pipes. Background Technology

[0002] When PE water supply pipes are laid outdoors, it is often necessary to extend the pipes according to actual needs. During this process, there will also be situations where the pipes need to be cut to adapt to the terrain or to install fittings such as joints and valves. Therefore, pipe cutting is often required. As an auxiliary tool for pipe laying, the pipe scraper is a grinding tool used after pipe cutting and before welding. It plays an extremely important role in the field of PE water supply pipe laying.

[0003] In existing PE pipe connections, adjacent PE pipes are joined using a butt welding machine. The pre-joint grinding process involves fixing the two retaining sleeves at the bottom of the PE pipe's mechanical rotating scraper onto the machine's smooth rod, then moving the PE pipe and the scraper to bring them into contact for grinding. However, the retaining sleeves at the bottom of the scraper are semi-circular, providing only basic positioning and not ensuring stability. This requires manual control by the operator, which is difficult and inconvenient, thus presenting a drawback. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanical rotating scraper for PE pipes, which solves the problem that existing mechanical rotating scrapers for PE pipes rely solely on a bottom fixing sleeve for positioning, resulting in instability and inconvenience in use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A mechanical rotary scraper for PE pipe includes a scraper frame, a handle on the top of the scraper frame, a drive motor mounted on one side of the scraper frame, a disc scraper rotatably mounted on the scraper frame below the drive motor, and a fixed sleeve at the bottom of the scraper frame that connects to the smooth rod of a docking machine. Both sides of the fixed sleeve have movable sleeves that can connect with the smooth rod of the docking machine. Both the fixed sleeve and the movable sleeve are semi-circular tube structures. A connecting plate is provided at the opposite ends of each movable sleeve. A circumferential groove is provided on the surface of the fixed sleeve, and a slider that slidably connects to the groove is provided on the connecting plate.

[0007] Preferably, the inner diameters of the fixed sleeve and the movable sleeve are the same, and the inner walls of both the fixed sleeve and the movable sleeve are movably inlaid with ball bearings.

[0008] Preferably, the fixed sleeve and the movable sleeve are slidably connected at their opposite ends.

[0009] Preferably, the two connecting plates at opposite ends of the movable sleeves on both sides of the fixed sleeve are respectively disposed on the front and back of the fixed sleeve.

[0010] Preferably, magnetic blocks are fixedly installed on both the bottom front and bottom back of the fixed sleeve, and an iron insert that can be attracted by the magnetic blocks is provided at the end of the connecting plate opposite to the movable sleeve.

[0011] Preferably, each of the connecting plates is provided with two sets of sliding grooves and sliders, the sliding grooves are parallel to each other, and the connecting plate is perpendicular to the sliding grooves.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes movable sleeves that can be swiveled on both sides of the fixed sleeve of the PE pipe mechanical rotary scraper. The fixed sleeve is engaged above the polished rod of the docking machine, and the movable sleeve is swiveled to engage below the polished rod. This ensures that the PE pipe mechanical rotary scraper does not wobble when moving left and right. It not only ensures that the scraper frame is perpendicular to the polished rod, but also maintains good stability during the left and right movement of the scraper frame. This achieves good positioning effect and high stability, which is beneficial to improving grinding accuracy. It solves the problem of instability and inconvenience caused by the existing PE pipe mechanical rotary scraper which only uses the fixed sleeve at the bottom for positioning.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-6 As shown, this utility model provides a technical solution: a mechanical rotary scraper for PE pipe, including a scraper frame 1, a handle 2 set on the top of the scraper frame 1, a drive motor 3 installed on one side of the scraper frame 1, a disc scraper 4 rotatably installed on the scraper frame 1 below the drive motor 3, and a fixing sleeve 6 at the bottom of the scraper frame 1 that connects with the smooth rod of the docking machine 5.

[0023] Both sides of the fixed sleeve 6 are provided with movable sleeves 7 that can be connected to the optical rod of the docking machine 5. The opposite ends of the fixed sleeve 6 and the movable sleeve 7 are slidably connected to improve the stability of the movable sleeve 7. Both the fixed sleeve 6 and the movable sleeve 7 are semi-circular tube structures with the same inner diameter. The inner walls of both the fixed sleeve 6 and the movable sleeve 7 are movably embedded with ball bearings 11. After the fixed sleeve 6 and the movable sleeve 7 are fitted onto the optical rod of the docking machine 5, they can slide along the optical rod.

[0024] Each of the opposite ends of the movable sleeve 7 is provided with a connecting plate 8. The surface of the fixed sleeve 6 is provided with a circumferential groove 9. The connecting plate 8 is provided with a slider 10 that is slidably connected to the groove 9. Each connecting plate 8 is provided with two sets of grooves 9 and sliders 10. The grooves 9 are parallel to each other, and the connecting plate 8 is perpendicular to the groove 9. Twisting the movable sleeve 7 can rotate the movable sleeve 7 to the bottom of the optical rod of the docking machine 5. With the fixed sleeve 6 above the optical rod of the docking machine 5, the scraper frame 1 can be stably installed on the optical rod of the docking machine 5 and can slide left and right without shaking.

[0025] Two connecting plates 8 at opposite ends of the movable sleeves 7 on both sides of the fixed sleeve 6 are respectively set on the front and back of the fixed sleeve 6. When installing, the movable sleeves 7 are turned in opposite directions so that the scraper frame 1 is stably installed on the smooth rod of the docking machine 5 and can slide left and right without shaking. Magnets 12 are fixedly installed on the bottom of the front and the bottom of the back of the fixed sleeve 6. The end of the connecting plate 8 opposite to the movable sleeve 7 is provided with an iron insert 13 that can be attracted by the magnet 12 to fix the position of the movable sleeve 7 and prevent it from loosening.

[0026] Working principle:

[0027] Using the handle 2, align the fixed sleeve 6 at the bottom of the scraper frame 1 with the smooth rod of the docking machine 5 below to complete the docking. Twist the movable sleeve 7 along the direction of the slide groove 9 so that the movable sleeve 7 rotates from above the smooth rod to below and locks it in place. With the cooperation of the upper fixed sleeve 6 and the lower movable sleeve 7, the scraper frame 1 is stably installed on the smooth rod of the docking machine 5. It can move left and right without wobbling back and forth or left and right, ensuring its stability. Then, the PE pipe and the scraper frame 1 can be moved. The drive motor 3 drives the disc scraper 4 to perform grinding work on the PE pipe. Throughout the process, the disc scraper 4 is always perpendicular to the smooth rod of the docking machine 5, which ensures high stability, standard grinding angle, and improved grinding accuracy.
