Description

Technical Field

[0001] This utility model relates to the field of PE pipe laying technology, specifically a rotatable support device that facilitates the laying of PE pipes. Background Technology

[0002] In the construction of PE pipe laying, because PE pipes are long, it is difficult to drag them directly on the ground, so pipe support devices are needed.

[0003] Traditional support methods often involve simple brackets or temporary support structures. These methods have many drawbacks, such as: they cannot adapt well to pipe movement, they are prone to causing wear on the pipe surface, and they have poor adaptability to PE pipes of different diameters. Therefore, this utility model provides a rotatable support device that facilitates the laying of PE pipes. Utility Model Content

[0004] To address the problems of traditional support methods failing to adapt well to pipe movement, easily causing pipe surface wear, and having poor adaptability to PE pipes of different diameters, this utility model provides a rotatable support device that facilitates the laying of PE pipes.

[0007] A central shaft, the top end of which is fixedly connected to a rotating body;

[0008] Rotating arms are distributed radially along the rotating body, and one end of the rotating arm is fixedly connected to the outer side of the rotating body. Multiple rotating arms are provided, and the multiple rotating arms are distributed in a circular array.

[0009] The number of arc-shaped sliding plates is the same as the number of rotating arms, and the arc-shaped sliding plates are fixedly installed between two adjacent rotating arms;

[0010] The core column is fixedly connected to the bottom end of the rotating arm, and a sleeve is fitted on the outside of the core column. The number of core columns is the same as the number of rotating arms, and multiple core columns form a circular frame.

[0023] The beneficial effects of this utility model are:

[0024] This invention, through the design of a central shaft, rotating arm, arc-shaped slide plate, core column, and sleeve, allows the arc-shaped slide plate to support the PE pipe during use. When the PE pipe is pulled forward, the overall structure consisting of the rotating arm and arc-shaped slide plate can rotate, reducing friction on the PE pipe and lowering the pulling force required to pull it forward. When the PE pipe is pulled forward, it slides inward, with the inner side of the PE pipe fitting against the surface of the sleeve. The sleeve can rotate relative to the core column, further reducing friction on the PE pipe and lowering the pulling force required to pull it forward, thus meeting practical usage requirements. Moreover, the entire structure is an open structure, adaptable to PE pipes of different diameters. Attached Figure Description

[0032] Please refer to the attached document. Figure 1 - Figure 4 This application illustrates a rotatable support device for facilitating the laying of PE pipes, used to support and guide the PE pipe 10 during the laying process. Specifically, it includes: a central shaft 3, a rotating arm 4, an arc-shaped sliding plate 6, a core column 7, and a sleeve 8.

[0033] A rotating body is fixedly connected to the top of the central shaft 3. The rotating body is a bearing-type connector. Rotating arms 4 are distributed radially along the rotating body, and one end of the rotating arm 4 is fixedly connected to the outside of the rotating body. Multiple rotating arms 4 are provided and arranged in a circular array. Multiple rotating arms 4 extend outward from the center. The number of arc-shaped slides 6 is the same as the number of rotating arms 4. The arc-shaped slides 6 are fixedly installed between two adjacent rotating arms 4. The area formed between two adjacent rotating arms 4 is fan-shaped. The shape of the arc-shaped slides 6 is also fan-shaped. The bottom end of the core column 7 is fixedly connected to the rotating arm 4. A sleeve 8 is sleeved on the outside of the core column 7. The number of core columns 7 is the same as the number of rotating arms 4. Multiple core columns 7 form a circular frame.

[0034] In use, the central shaft 3 is fixed, and the PE pipe 10 is set on the arc-shaped slide plate 6 to support the PE pipe 10. When the PE pipe 10 is pulled forward, the overall structure consisting of the rotating arm 4 and the arc-shaped slide plate 6 can rotate, reducing the friction of the PE pipe 10 and reducing the pulling force required to pull the PE pipe 10 forward. When the PE pipe 10 is pulled forward, the PE pipe 10 slides inward, and the inner side of the PE pipe 10 is attached to the surface of the sleeve 8. The sleeve 8 can rotate relative to the core column 7, further reducing the friction of the PE pipe 10 and reducing the pulling force required to pull the PE pipe 10 forward, thus meeting the actual use requirements.

[0035] In one embodiment, in order to enhance the structural strength of the circular frame composed of multiple core pillars 7, a top plate 9 is fixedly connected to the top of the multiple core pillars 7, thereby ensuring that the top of the multiple core pillars 7 is in a stable state (the structure is more stable compared to the suspended method).

[0036] In one embodiment, a fixing member 5 is fixedly connected to the end of the rotating arm 4 away from the rotating body. The fixing member 5 is cylindrical. When changing the direction of the PE pipe 10 using a rotatable support device that facilitates the laying of PE pipes, the PE pipe 10 can be placed between two adjacent fixing members 5 to prevent the PE pipe 10 from detaching from the rotatable support device that facilitates the laying of PE pipes. The PE pipe 10 is straight and will generate elasticity after being bent. If the fixing member 5 is not designed, the PE pipe 10 will detach from the support of the rotatable support device that facilitates the laying of PE pipes during actual use.

[0037] In one embodiment, the rotating body is a bearing, which includes at least an inner ring, rolling elements and an outer ring. The inner ring and the outer ring can rotate relative to each other. The inner ring of the bearing is fixedly connected to the central shaft 3. Generally, a stepped shaft is designed at the top of the central shaft 3. The inner ring of the bearing is interference-fitted with the stepped shaft, and the bearing is supported by the stepped part. The outer ring of the bearing is fixedly fitted with a mounting ring, which is made of general metal material and can be connected to the rotating arm 4 by welding.

[0038] In one embodiment, in order to facilitate the fixing of the central shaft 3, a base 1 is fixedly connected to the bottom end of the central shaft 3. The top of the base 1 is provided with a plurality of fixing holes 2. The base 1 is fixed by bolts / screws, thereby fixing the central shaft 3.

[0039] In one embodiment, an elastic rope 11 is connected between the rotating arm 4 and the base 1. After the elastic rope 11 is connected, it can limit the rotation angle of the entire structure formed by the rotating arm 4 and the arc-shaped slide plate 6. That is, after the entire structure formed by the rotating arm 4 and the arc-shaped slide plate 6 rotates, the elastic rope 11 generates elastic force. When the friction between the PE pipe 10 and the arc-shaped slide plate 6 is small, the entire structure formed by the rotating arm 4 and the arc-shaped slide plate 6 automatically returns to its original position, preventing the entire structure formed by the rotating arm 4 and the arc-shaped slide plate 6 from rotating, causing the fixing member 5 to rotate, and bending / damaging the PE pipe.

[0040] In one embodiment, a rubber pad is provided on the top of the arc-shaped slide plate 6. The rubber pad supports the PE pipe 10 and can effectively reduce the wear of the pipe during the laying process.

[0041] During use, the PE pipe 10 rests on top of the arc-shaped sliding plate 6, with rubber pads reducing wear between them. As the PE pipe 10 moves forward, its inner side contacts the sleeve 8. The sleeve 8 and the core column 7 can rotate, reducing friction on the inner side of the PE pipe 10. Furthermore, the entire structure formed by the rotating arm 4 and the arc-shaped sliding plate 6 can also rotate, buffering the impact between the PE pipe 10 and the arc-shaped sliding plate 6, effectively protecting the PE pipe 10.
