Abstract
Description
Technical Field
[0001] This utility model belongs to the field of PE pipe technology, and in particular relates to a reinforcement component for PE pipes. Background Technology
[0002] In the field of pipeline engineering, PE pipes are widely used due to their advantages such as corrosion resistance and good flexibility. Reinforcing components for PE pipes are key parts that ensure their stable operation under complex working conditions. They are mainly used to enhance the pipe's resistance to pressure and deformation, and to prevent damage to the pipe due to external forces, temperature changes, and other factors.
[0003] Currently, existing PE pipe reinforcement components are single cylindrical structures. These reinforcement components are usually prefabricated according to common pipe specifications. When in use, the cylindrical body is directly placed on the outside of the PE pipe, and the rigid structure of the cylindrical body provides simple external support for the pipe.
[0004] However, existing PE pipe reinforcement components have the following drawbacks in practical use: First, due to the fixed structure of existing PE pipe reinforcement components, it is difficult to adapt to the needs of pipes of different lengths. When different lengths of PE pipes are involved in the laying of projects, it is necessary to re-customize or modify the reinforcement cylinder for each length specification, which not only greatly increases the production cost, but also prolongs the construction period and reduces the efficiency of the project. Second, existing PE pipe reinforcement components lack an effective bending angle limiting mechanism when facing the reinforcement of PE bends.
[0005] Therefore, it is essential to invent a reinforcement component for PE pipes. Utility Model Content
[0006] To address the above problems, this utility model proposes a reinforcement component for PE pipes, and the technical solution used is as follows:
[0007] A reinforcement component for PE pipes includes a fixed sleeve, connecting columns, slide rails, and compression frames. At least two fixed sleeves are provided, and several connecting columns are rotatably installed between adjacent fixed sleeves. The fixed sleeves are all fixed to the outer side of the PE pipe. Each connecting column has a slide rail inside, and several compression frames are slidably installed inside each slide rail. The actuating end of each compression frame is fitted against the outer side of the PE pipe.
[0008] Furthermore, the fixing sleeve includes a half-cylinder, side plates, rotating columns, and nuts. Two half-cylinders are provided, and the inner diameter of the complete cylinder formed by the two half-cylinders is adapted to the diameter of the PE pipe. Both ends of the half-cylinder are fixed with side plates by welding, and the corresponding side plates are fixed together by bolts. Two rotating columns are fixed to the outer surface of the half-cylinder by welding. Nuts are fixed to the outer surface of the rotating columns by thread engagement, and a connecting column is rotatably installed on the rotating column. The connecting column is located between the nut and the half-cylinder. This arrangement facilitates fixing the fixing sleeve to the PE pipe and facilitates fixing and disassembling the connecting column.
[0009] Furthermore, a first rubber pad is fixed to the inner wall of each of the semi-cylinders. The inner wall of the first rubber pad is provided with a grid-like groove. This arrangement can not only prevent the semi-cylinder from damaging the PE pipe, but also prevent the semi-cylinder from sliding on the PE pipe.
[0010] Furthermore, the extrusion frame includes a slider, a screw, and an arc plate. The slider is slidably installed inside the slide rail, and the screw passes through the inside of the slider through a threaded engagement. A hexagonal prism is welded to the end of the screw away from the PE pipe, and an arc plate is rotatably installed at the end of the screw close to the PE pipe. The shape of the arc plate is adapted to the shape of the PE pipe. This arrangement enables the PE pipe between the two fixed sleeves to be extruded and reinforced.
[0011] Furthermore, a second rubber pad is fixed to the side of the arc-shaped plate away from the screw. The inner wall of the second rubber pad is provided with a grid-like groove. This arrangement can not only prevent the arc-shaped plate from damaging the PE pipe, but also prevent the arc-shaped plate from sliding on the PE pipe.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] The design of this utility model allows for the selection of an appropriate number of fixing sleeves to reinforce the PE pipe as needed, and the fixing sleeves are then fixed onto the PE pipe. Adjacent fixing sleeves are connected together via a connecting column through the cooperation of a rotating column and a nut. This simultaneously reinforces the PE pipe using the fixing sleeves and the compression frame. Furthermore, since the connecting column can rotate on the rotating column, the angle of the connecting column on the rotating column can be changed, and the fixing sleeves can be fixed at corresponding positions on the PE pipe, thereby limiting the bending angle of the PE pipe in a bent state.

[0025] Please see Figures 1 to 6As shown, this utility model is a reinforcement component for PE pipes, including a fixed sleeve 1, a connecting column 2, a slide rail 3, and an extrusion frame 4. At least two fixed sleeves 1 are provided, and several connecting columns 2 are rotatably installed between adjacent fixed sleeves 1, and the fixed sleeves 1 are all fixed to the outer side of the PE pipe 5. The connecting column 2 is provided with a slide rail 3, and several extrusion frames 4 are slidably installed inside the slide rail 3. The actuating end of the extrusion frame 4 is fitted to the outer side of the PE pipe 5.
[0026] Specifically, the fixing sleeve 1 includes a half-cylinder 11, side plates 12, rotating columns 13, and nuts 14. Two half-cylinders 11 are provided, and the diameter of the complete cylinder formed by the two half-cylinders 11 is adapted to the diameter of the PE pipe 5. Side plates 12 are fixed to both ends of the half-cylinder 11 by welding, and the corresponding side plates 12 are fixed together by bolts. Two rotating columns 13 are fixed to the outer side of the half-cylinder 11 by welding. Nuts 14 are fixed to the outer side of the rotating columns 13 by thread engagement, and a connecting column 2 is rotatably installed on the rotating column 13. The connecting column 2 is located between the nut 14 and the half-cylinder 11. In use, the two half-cylinders 11 can be respectively fitted to the outer side of the PE pipe 5, and then the corresponding side plates 12 are fixed together by bolts, thereby fixing the fixing sleeve 1 to the PE pipe 5. Then, the nut is removed from the rotating column 13, and one end of the connecting column 2 is put on the corresponding rotating column 13. Then, the nut 14 is reset, so that the corresponding fixing sleeves 1 can be connected together by the connecting column 2.
[0027] Specifically, a first rubber pad 15 is fixed to the inner wall of each half-cylinder 11. The inner wall of the first rubber pad 15 is provided with a grid-like groove. With this arrangement, the first rubber pad 15 can prevent the half-cylinder 11 from damaging the PE pipe 5. Moreover, the grid-like groove on the inner wall of the first rubber pad 15 can increase the friction coefficient between the first rubber pad 15 and the PE pipe 5, thereby preventing the half-cylinder 11 from sliding on the PE pipe 5.
[0028] Specifically, the extrusion frame 4 includes a slider 41, a screw 42, and an arc plate 43. The slider 41 is slidably installed inside the slide rail 3, and the screw 42 passes through the inside of the slider 41 through thread engagement. A hexagonal prism is fixed to the end of the screw 42 away from the PE pipe 5 by welding, and an arc plate 43 is rotatably installed to the end of the screw 42 close to the PE pipe 5. The shape of the arc plate 43 is adapted to the shape of the PE pipe 5. In use, after the fixing sleeve 1 is fixed to the PE pipe 5, the arc plate 43 can be used to extrude and reinforce the PE pipe 5 between the two fixing sleeves 1 by rotating the screw 42. Furthermore, through the cooperation of the slider 41 and the slide rail 3, the arc plate 43 can reinforce different positions of the PE pipe 5.
[0029] Specifically, a second rubber pad 44 is fixed to the side of the arc plate 43 away from the screw 42. The inner wall of the second rubber pad 44 is provided with a grid-like groove. This arrangement can prevent the arc plate 43 from damaging the PE pipe 5. The grid-like groove on the inner wall of the second rubber pad 44 can increase the friction coefficient between the second rubber pad 44 and the PE pipe 5, thereby preventing the arc plate 43 from sliding on the PE pipe 5.
[0030] Please see Figure 1-6 As shown, this utility model is a reinforcement component for PE pipes. Its working principle is as follows: When in use, firstly, according to the required length of the PE pipe 5 to be reinforced, select an appropriate number of fixing sleeves 1, then fix the fixing sleeves 1 on the PE pipe 5. Next, through the cooperation of the rotating column 13 and the nut 14, the adjacent fixing sleeves 1 are connected together through the connecting column 2. Then, adjust the position of the extrusion frame 4 on the connecting column 2 so that the extrusion frame 4 reinforces the PE pipe 5.
