[0002] PE (polyethylene) is a common plastic material with good toughness and durability, and is widely used in various fields. In the pipeline field, PE material has become an ideal transportation medium due to its excellent performance and environmental protection characteristics. Whether transporting drinking water, sewage or other fluid media, PE pipelines can operate stably and reliably without causing pollution to the environment, and are therefore favored by industries such as water conservancy projects.

However, in most water conservancy projects, one end of the large-diameter PE pipe is dragged while the other end lacks proper support. This results in significant surface friction damage during the pulling process, which in turn affects the quality and service life of the pipe. Utility Model Content

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Please see Figure 1-4 As shown, a traction device for large-diameter PE pipes includes a support base 1, a side box 2 fixed on one side of the surface of the support base 1, sliding blocks 3 slidably arranged on both sides of the surface of the support base 1, an inclined block 4 hinged to the surface of the sliding block 3, a placement roller 5 rotatably arranged on the surface of the inclined block 4, a moving mechanism 6 for adjusting the sliding blocks 3 on both sides in the inner cavity of the side box 2, an adjusting mechanism 7 for adjusting the angle of the inclined block 4 in the inner cavity of the support base 1, and an auxiliary mechanism 8 in the inner cavity of the support base 1.

[0020] In use, this utility model can support large-diameter PE pipes through the placement rollers 5 on both sides, thereby facilitating the traction of large-diameter PE pipes. In addition, under the action of the moving mechanism 6, the distance between the placement rollers 5 on both sides can be adjusted, thus making it suitable for PE pipes of different sizes. Furthermore, under the action of the adjusting mechanism 7, the angle of the placement rollers 5 on both sides can be adjusted, thereby further improving the applicability of this device. In addition, under the action of the auxiliary mechanism 8, the contact mode between this device and the ground can be changed, making it easier for this device to work and improving its practicality.

[0021] The moving mechanism 6 includes a motor 61 fixed to the inner cavity of the side box 2. The output shaft of the motor 61 is fixed with a bidirectional threaded rod 62. The sliding blocks 3 on both sides mesh with the surface of the bidirectional threaded rod 62. One end of the bidirectional threaded rod 62 is rotatably provided with a bearing seat 63. The bearing seat 63 is fixed to the surface of the support base 1. In this embodiment, through the arrangement of the motor 61, the bidirectional threaded rod 62 and the bearing seat 63, when the motor 61 is working, the bidirectional threaded rod 62 fixed to the surface of the motor 61 can mesh with the sliding blocks 3 on both sides. Then, with the auxiliary support of the bearing seat 63, the sliding blocks 3 on both sides drive the tilting block 4 and the placement roller 5 to adjust their positions.

[0022] The adjustment mechanism 7 includes several hinges 71 fixed to both sides of the surface of the inclined block 4 and a first electric push rod 76 fixed to the inner cavity of the support base 1. The other end of the hinge 71 is hinged to a piston push rod 72. A piston tube 73 is slidably disposed on the surface of the piston push rod 72. The piston tube 73 is hinged to the surface of the sliding block 3. The other end of the piston tube 73 is connected to a connecting pipe 74. The other end of the connecting pipe 74 is connected to a piston member 75. The piston member 75 moves by the piston through the first electric push rod 76. In this embodiment, through the arrangement of the hinges 71, piston push rod 72, piston tube 73, connecting pipe 74, piston member 75 and first electric push rod 76, the piston member 75 is made to work under the action of the first electric push rod 76. Then, under the action of the piston member 75, the oil pressure in the connecting pipe 74 changes. Then, under the action of several piston tubes 73, the piston push rod 72 drives the hinges 71 to work. Thus, with the assistance of the sliding block 3, the inclined block 4 drives the placement roller 5 to change angle.

[0023] The auxiliary mechanism 8 includes a second electric push rod 81 fixed to the inner cavity of the support base 1. The output shaft of the second electric push rod 81 is fixed with a push plate 82. Several connecting rods 83 are fixed on the surface of the push plate 82. Guide wheels 84 are fixed on the surface of the connecting rods 83. In this embodiment, through the arrangement of the second electric push rod 81, the push plate 82, the connecting rods 83 and the guide wheels 84, the push plate 82 moves through the connecting rods 83 to drive the several connecting rods 83 to move under the action of the second electric push rod 81. Then, under the action of the guide wheels 84, the device can be raised, so that the device can be moved through the guide wheels 84.

[0024] The inner cavity of the support base 1 has grooves 10 on both sides, and sliders 9 are fixed on both sides of the surface of the push plate 82. The sliders 9 slide on the surface of the grooves 10. In this embodiment, the sliders 9 and the grooves 10 provide a limit for the sliding of the push plate 82 when it slides, thereby improving the stability of the push plate 82 when it slides.

[0025] Motor 61 is a servo motor and has a built-in brake device. In this embodiment, this setting allows the bidirectional threaded rod 62 to stop stably at a specified angle, thereby improving the stability of the sliding blocks 3 on both sides at a certain position.

[0026] Working principle: During water conservancy construction, large-diameter PE pipes may need to be pulled. When performing this work, the worker can use the auxiliary mechanism 8. Under the action of the second electric push rod 81, the push plate 82 drives the connecting rod 83 to move up and down, thereby making several guide wheels 84 support the ground. The second electric push rod 81 pushes the device upward, so that the guide wheels 84 support the device. Then the worker can push the device to the designated position through the guide wheels 84.

[0027] Once the pipe reaches the designated location, the staff can support the large-diameter PE pipe using the placement rollers 5 on both sides, and then pull the large-diameter PE pipe with the help of the large equipment on the other side.

[0028] When supporting large-diameter PE pipes with placement rollers 5, workers can use the moving mechanism 6. Under the action of motors 61 on both sides, the bidirectional threaded rod 62 and bearing seat 63 are activated, thereby adjusting the distance between the two placement rollers 5. This is suitable for large-diameter PE pipes of different specifications. In addition, under the action of the first electric push rod 76, the piston 75 works through the connecting pipe 74 to the piston tube 73. Then, under the action of the piston push rod 72, the angle of the tilting block 4 is adjusted through the hinge 71, so that the angle of the two placement rollers 5 changes, thereby improving the adaptability of placement rollers 5 to different large-diameter PE pipes.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
