[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figures 1 to 6A PE pipe welding positioning device includes a base frame 1, on which two supports 2 are provided, and a receiving frame 3 is provided on the top of each of the two supports 2;
[0029] The top of the receiving frame 3 is provided with a mounting frame 4. A rotating rod 5 is rotatably mounted on the mounting frame 4 via a rotating shaft. A positioning part is provided on one side of the rotating rod 5, and a pressing part is provided on the other side of the rotating rod 5. The positioning part assists in moving the pipe to a suitable position, and the pressing part restricts the pipe.
[0030] The inner walls of both receiving frames 3 are provided with supporting moving components to assist in placing materials onto the receiving frames 3.
[0031] When in use, this device uses a base frame 1, which serves as the main load-bearing structure. Two supports 2 support the top support frame 3, forming a stable operating platform that can reliably withstand various forces during pipe placement and welding. The mounting bracket 4 on the top of the support frame 3 is rotatably connected to the rotating rod 5 via a rotating shaft. This allows the positioning part on one side of the rotating rod 5 and the pressing part on the other side to work together. The positioning part helps the pipe to be accurately positioned. Once accurately positioned, the rotating shaft rotates the rod 5, causing the pressing part to move downward and applying appropriate pressure from the other side. This provides a stable constraint on the pipe, effectively preventing axial or radial displacement during welding and ensuring precise alignment of the two pipe sections to be welded, thus significantly improving welding quality.
[0032] Furthermore, the positioning part includes a connecting rod 6 rotatably disposed on one side of the rotating rod 5. A positioning wheel 7 is rotatably mounted on the bottom end of the connecting rod 6. The connecting rod 6 is vertically disposed above the receiving frame 3. The positioning wheel 7 contacts the surface of the pipe. During the placement of the pipe, the positioning wheel 7 can not only provide lateral positioning for the pipe to prevent it from moving left or right, but also rotate with slight adjustments to the pipe, reducing frictional damage to the pipe surface and assisting the pipe in moving to the appropriate position.
[0033] Furthermore, the pressing part includes a mounting base 8 disposed on the receiving frame 3. The mounting base 8 has a groove 9, and a limiting plate 10 is slidably disposed in the groove 9. Several springs 11 are installed on the top of the limiting plate 10, and a horizontal plate 12 is installed on the top of the springs 11. The limiting plate 10 is located above the pipe, and the springs 11 are disposed between the horizontal plate 12 and the limiting plate 10. A support rod 13 is fixedly installed on the horizontal plate 12, and one side of the support rod 13 is rotatably connected to one end of the rotating rod 5. Through the limiting plate 10, springs 11 and horizontal plate 12 in the mounting base 8, the limiting plate 10 is pressed tightly against the pipe under the elastic force of the springs 11, realizing the longitudinal pressing and positioning of the pipe. The support rod 13 on the horizontal plate 12 is connected to the rotating rod 5. The rotation of the rotating rod 5 can drive the limiting plate 10 to move up and down, which facilitates the removal and placement of the pipe. Moreover, the elastic characteristics of the springs 11 can adapt to pipes of different diameters, so that the device can effectively press and hold pipes of various specifications, improving the versatility of the device.
[0034] Furthermore, a mounting plate 14 is provided on one side of the mounting frame 4. The mounting plate 14 is fixedly connected to the end of the corresponding rotating shaft of the mounting frame 4. A plurality of limiting holes 15 are provided on one side of the mounting plate 14. An insertion hole 16 is provided on the side of the mounting frame 4 near the mounting plate. The positions of the insertion hole 16 and the plurality of limiting holes 15 correspond to each other. A limiting rod 23 is provided on one side of the mounting plate 14. The limiting rod 23 is adapted to the limiting holes 15 and the insertion hole 16. The mounting plate 14 is fixedly connected to the rotating shaft. The positions of the plurality of limiting holes 15 on one side of the mounting plate 14 correspond to the positions of the insertion holes 16 on the mounting frame 4. The limiting rod 23 can be inserted into different limiting holes 15 and insertion holes 16 to fix the rotation angle of the rotating rod 5. The force exerted on the pipe by the positioning part and the pressing part can be flexibly adjusted according to the pipe diameter to ensure stable pressure during welding and enhance the adjustment flexibility and applicability of the device.
[0035] Furthermore, the plurality of limiting holes 15 are arranged in a ring array on the mounting plate 14, which allows the rotating rod 5 to be fixed at multiple angles, further expanding the adaptability range of the device to pipes of different specifications. Operators can more accurately adjust the positioning and holding angles to ensure that the positioning effect meets the welding requirements.
[0036] Optionally in this embodiment, the bottom of the limiting plate 10 is provided with an arc-shaped groove 18 for limiting the pipe. The arc-shaped groove 18 at the bottom of the limiting plate 10 matches the shape of the pipe, increasing the contact area between the limiting plate 10 and the pipe, improving the limiting effect on the pipe, effectively preventing the pipe from rotating or shifting during welding, ensuring precise connection of the welding joints of the two pipe sections, and guaranteeing welding quality.
[0037] Furthermore, the supporting moving assembly includes several connecting frames 19 disposed on the inner wall of the receiving frame 3 and auxiliary rollers 20 rotatably disposed on the connecting frames 19. The auxiliary rollers 20 on the connecting frames 19 convert the sliding friction between the pipe and the receiving frame 3 into rolling friction, which greatly reduces the resistance when the pipe moves, making it easier to quickly place the pipe at the designated position of the receiving frame 3, and improving the convenience and efficiency of operation.
[0038] Furthermore, a guide rail 21 is provided on one side of the upper surface of the base frame 1, and one of the supports 2 is slidably mounted on the guide rail 21. The guide rail 21 on the base frame 1 allows one of the supports 2 to slide, so that the distance between the two supports 2 can be adjusted according to the pipe length, which can meet the welding positioning requirements of pipes of different lengths, making the device more applicable and enhancing its practicality.
[0039] Furthermore, the lower surface of the base frame 1 is equipped with several movable wheels 22. These wheels 22 allow for flexible adjustment of the device's placement position according to changes in the welding operation location, thereby improving the device's mobility and usability.
[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
