Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for pipe production, specifically a multi-claw traction machine for PE pipe production. Background Technology
[0002] The multi-claw pipe traction machine is a traction device used in pipe production. Its key feature is its multiple claws, which enable more effective traction and fixation of pipes, ensuring stability and precision during production. Driven by a motor, a traction chain or track moves the claws across the pipe surface, applying traction force. Currently, traction machines adjust the gap according to pipe diameter using spring-loaded rollers. However, when faced with production demands for larger pipe diameters, the spring-loaded rollers are insufficient. The excessive spring pressure on larger diameter pipes often deforms the vacuum-cooled and shaped pipe. Therefore, to meet production demands for larger diameters, new traction machines must be purchased, significantly increasing costs. Thus, further improvements to the pipe traction machine are needed to meet diverse production requirements. Utility Model Content
[0003] To address the above technical problems, this utility model provides a multi-claw traction machine for PE pipe production.
[0004] To solve the above-mentioned technical problems, the present invention provides a multi-claw traction machine for PE pipe production, comprising a base, two lower roller shafts rotatably connected to the base, telescopic cylinders fixedly connected to both sides of the top of the base, the output ends of the telescopic cylinders being fixedly connected to a crossbeam, two upper roller shafts rotatably connected to the crossbeam, a traction belt wound between the two upper roller shafts and between the two lower roller shafts, a plurality of traction claws fixedly connected to the traction belt, a telescopic guide rail fixedly connected between the crossbeam and the base, one of the upper roller shafts being drive-connected to the output end of a second motor, and one of the lower roller shafts being drive-connected to the output end of a first motor, both the first and second motors being fixedly connected to the base, and a controller being fixedly connected to the base, the first motor, the second motor, and the telescopic cylinders being controlled by the controller.
[0005] Furthermore, a limit frame is fixedly connected to the top of the base on the side of the traction machine input end.
[0006] Furthermore, a level is fixedly connected to the crossbeam.
[0007] Furthermore, one side of the traction claw is fixedly connected to the traction belt, and the other side is a downwardly recessed mechanism.
[0008] This utility model has the following advantages compared with the prior art:
[0009] This invention uses a telescopic cylinder to adjust the distance between the upper and lower traction mechanisms, allowing for both fine-tuning and larger-scale adjustments to meet various production needs. A level ensures the upper traction belt is horizontal, guaranteeing uniform traction on the PE pipe and preventing deformation due to excessive localized stress. A limit frame at the input end of the traction machine limits the pipe's movement, preventing derailment during traction. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 4 The multi-claw traction machine for PE pipe production shown includes a base 1, with two lower rollers 3 rotatably connected to the base 1. Two telescopic cylinders 8 are fixedly connected to both sides of the top of the base 1, and the output ends of the telescopic cylinders 8 are fixedly connected to a crossbeam 6. Two upper rollers 2 are rotatably connected to the crossbeam 6. A traction belt 4 is wound between the two upper rollers 2 and between the two lower rollers 3. Several traction claws 5 are fixedly connected to the traction belt 4. Two telescopic guide rails 7 are fixedly connected between the crossbeam 6 and the base 1 on both sides. The telescopic guide rails 7 have an inner and outer sleeve structure and a bolt locking structure. One of the upper rollers 2 is connected to the output end of the second motor 13 through a sprocket material transmission, and one of the lower rollers 3 is also connected to the output end of the first motor 9 through a sprocket material transmission. The first motor 9 and the second motor 13 are both fixedly connected to the base 1. A controller 12 is fixedly connected to the base 1. The first motor 9, the second motor 13, and the telescopic cylinders 8 are all controlled by the controller 12.
[0017] In order to limit the PE pipe, a limit frame 10 is fixedly connected to the top of the base 1 on the side of the traction machine input end to prevent the pipe from derailing due to other factors during the traction process.
[0018] To ensure that the upper traction belt 4 is level, a level 11 is fixedly connected to the crossbeam 11, which can apply a uniform force to the pipe during the traction process and avoid excessive local stress on the pipe and deformation.
[0019] To enhance the traction effect of the traction claw 5, one side of the traction claw 5 is fixedly connected to the traction belt 4, and the other side is a downward-recessed mechanism to ensure that the pipe is always in the middle of the traction claw 5, further preventing the pipe from derailing during the traction process.
[0020] It should be noted that the telescopic cylinder 8 in this embodiment is a hydraulic telescopic cylinder, and the telescopic guide rail 7 and the level 11 are all existing devices. The specific structure will not be described in detail.
[0021] The working process of this embodiment is as follows:
[0022] First, determine the spacing between the upper and lower traction belts 4 of the traction machine according to the diameter of the PE pipe to be produced. Remove the chains from the motors on both sides. Then, control the telescopic cylinder 8 through the controller 12 to adjust the spacing between the upper and lower traction belts 4 to the required spacing. Use the level 11 to observe whether the upper crossbeam 6 is horizontal to ensure that the traction belts 4 are horizontal and to ensure that uniform pressure is applied to the PE pipe. After confirming that it is horizontal, lock the telescopic guide rail 7. Then, install chains of appropriate length according to the sprocket spacing between the upper roller shaft 2 and the second motor 13 and the sprocket spacing between the lower roller shaft 3 and the first motor 9. Then, the controller 12 can be used to turn on the first motor 9 and the second motor 13. The two motors rotate in opposite directions, and the first motor 9 rotates counterclockwise. Pass the vacuum-cooled and shaped PE pipe through the limiting frame 10 and place it between the traction claws 5 on the upper and lower traction belts 4 to achieve traction of the PE pipe. If other diameter PE pipes need to be produced, repeat the above adjustment steps.
