Description

Technical Field

[0001] This utility model relates to the field of MMP pipes, and in particular to an impact-resistant and wear-resistant protective sleeve for MMP pipes. Background Technology

[0002] MPP (modified polypropylene) pipes are widely used in the protection of various underground pipelines in power, communication, and municipal engineering. Due to their excellent corrosion resistance, wear resistance and mechanical strength, MPP pipes can effectively protect underground lines from damage caused by external environmental factors such as impact, wear and corrosion. Their superior anti-aging properties and good high-temperature resistance ensure that the pipelines can operate safely and stably for a long time in complex underground environments.

[0003] Existing traditional MPP pipe protective sleeves often adopt an integrated sleeve design. However, this type of protective sleeve needs to be inserted from one end of the pipeline to be protected. This means that both installation and removal of the protective sleeve can only be done from one end of the pipeline. If the protective sleeve needs to be installed or removed in the middle of the pipeline, the installation and removal operation will be inconvenient and impractical. Therefore, an impact-resistant and wear-resistant protective sleeve for MPP pipes is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an impact-resistant and wear-resistant protective sleeve for MPP pipes. It aims to improve upon the existing technology where some traditional MPP pipe protective sleeves are often directly integrated into the pipe sleeve form. However, such protective sleeves need to be inserted from one end of the pipe to be protected, which makes it inconvenient to install or remove the protective sleeve only from one end of the pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an impact-resistant and wear-resistant protective sleeve for MPP pipes, comprising a pipe sleeve, wherein a buffer sleeve is provided inside the pipe sleeve, the pipe sleeve includes a first sleeve plate, and a second sleeve plate is provided at the lower part of the first sleeve plate. The first sleeve plate and the second sleeve plate are symmetrically arranged and both are semi-circular arc-shaped. The bottom left and right sides of the first sleeve plate are provided with slots, and the inner walls of the slots are fixedly connected to multiple limit strips on the left and right sides. The top left and right sides of the second sleeve plate are fixedly connected with locking strips, which are movably connected to the slots. The locking strips are provided with multiple limit grooves on the left and right sides, and the limit strips are movably connected to the limit grooves.

[0007] The top of the card strip is designed as an arc surface.

[0008] As a further description of the above technical solution:

[0009] The outer walls of both sleeve plate one and sleeve plate two are fixedly connected with wear-resistant layers.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 The present invention provides an embodiment of an impact-resistant and wear-resistant protective sleeve for MPP pipes, comprising a sleeve 1, which is a protective sleeve for MPP pipes, and a buffer sleeve 2 inside the sleeve 1, which is made of rubber. The sleeve 1 includes a first sleeve plate 11, and a second sleeve plate 12 is provided at the lower part of the first sleeve plate 11. The first sleeve plate 11 and the second sleeve plate 12 are symmetrically arranged and are both semi-circular arc-shaped. The two sleeve plates can form a circular tube. The outer walls of the first sleeve plate 11 and the second sleeve plate 12 are fixedly connected with a wear-resistant layer 13, which can be ultra-high molecular weight polyethylene or nylon reinforced layer.

[0032] Furthermore, the bottom left and right sides of the first sleeve 11 are provided with slots 111 for mounting the clip 121. The inner walls of the slots 111 are fixedly connected to multiple limit strips 112 on the left and right sides for limiting the clip 121. The top left and right sides of the second sleeve 12 are fixedly connected with clips 121, which cooperate with the slots 111 to connect the two sleeves. The clips 121 are movably connected to the slots 111. The left and right sides of the clips 121 are provided with multiple limit grooves 122 for connecting the limit strips 112. The limit strips 112 are movably connected to the limit grooves 122. The top of the clips 121 is set as an arc surface 123, which can better push the limit strips 112, so that the clips 121 can be smoothly inserted into the slots 111.

[0033] like Figures 4-5 As shown, the buffer sleeve 2 includes a first gasket 21, which is fixedly connected to the inner wall of the sleeve plate 11. A second gasket 22 is provided at the lower part of the first gasket 21. Both the first gasket 21 and the second gasket 22 are arc-shaped and are compatible with each other. The second gasket 22 is fixedly connected to the inner wall of the sleeve plate 12. Multiple buffer strips 23 are fixedly connected to the inner walls of both the first gasket 21 and the second gasket 22. These are semi-annular convex strips. Connecting grooves 211 are provided on the bottom surfaces of the left and right sides of the first gasket 21. Connecting strips 221 are fixedly connected to the top surfaces of the left and right sides of the second gasket 22. The connecting strips 221 are movably connected to the connecting grooves 211 and are used to connect the first gasket 21 and the second gasket 22. A buffer cavity 231 is provided in the middle of the buffer strip 23 for cushioning when subjected to impact.

[0034] Working principle: During installation, firstly, sleeve plate one 11 and sleeve plate two 12 are placed on the upper and lower sides of the pipeline, respectively. Then, the slot 111 on sleeve plate one 11 is aligned with the retaining strip 121 on sleeve plate two 12, so that the retaining strip 121 can be inserted into the slot 111. When the retaining strip 121 is inserted into the slot 111, the arc surface 123 on the upper part of the retaining strip 121 will push the limiting strips 112 on both sides of the slot 111 to assist the retaining strip 121 in being smoothly inserted into the slot 111. After the retaining strip 121 is inserted into the slot 111, multiple limiting strips 112 will be locked in the limiting grooves 122 on both sides of the retaining strip 121, thereby completing the connection between sleeve plate one 11 and sleeve plate two 12. When sleeve 11 and sleeve 22 are fixed, the first gasket 21 and the second gasket 22 on the inner side of sleeve 11 and sleeve 22 will also be connected together. The connecting strip 221 on the second gasket 22 will be inserted into the connecting groove 211 on the first gasket 21. At the same time, the buffer strip 23 on the inner side of the first gasket 21 and the second gasket 22 will press against the outer wall of the pipeline, so that when the pipeline is impacted, the force can be buffered in time, thereby protecting the pipeline. At the same time, the wear-resistant layer 13 on the outer side of sleeve 11 and sleeve 22 can effectively improve the wear resistance of the protective sleeve, thereby better protecting the pipeline.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
