Description

Technical Field

[0001] This utility model relates to the field of sleeve devices, and in particular to a highly applicable corrosion-resistant sleeve. Background Technology

[0002] Corrosion-resistant sleeves are steel pipes that have undergone anti-corrosion processing to effectively prevent or slow down corrosion caused by chemical or electrochemical reactions during transportation and use. These sleeves protect the pipeline from corrosion, air pressure, and other external forces. This treatment involves applying an anti-corrosion coating to both the outer and inner walls to reduce external erosion and internal corrosion, thereby extending service life and ensuring safe pipeline operation. Corrosion-resistant sleeves are widely used in pipelines in the oil, natural gas, and other energy industries. In harsh environments such as polar regions and oceans, they are widely used due to their excellent joint properties, physical performance, and chemical stability.

[0003] During the installation of anti-corrosion sleeves, the sleeves need to be fixed on the line first by welding, threaded connection or other means, and then the conveying pipeline is put into the sleeves to protect the conveying pipeline and reduce the impact of external forces such as corrosion, air pressure and compression on the conveying pipeline.

[0004] Currently, when installing pipelines into anti-corrosion sleeves, they are directly pushed into the sleeve. This method has little impact on pipelines made of plastic, but for pipelines made of metal, direct pushing causes friction between the metal and the anti-corrosion layer on the inner wall of the sleeve, thereby reducing the corrosion resistance of the sleeve and shortening the service life of both the sleeve and the pipeline. Moreover, in actual use, sleeves come in various sizes, requiring workers to handle multiple sizes. Generally, workers can only handle two sleeves at a time. If multiple sleeves are stacked and handled, it will damage the outer wall of the sleeve, affecting the quality of the sleeve and reducing work efficiency.

[0005] Therefore, it is necessary to propose a corrosion-resistant casing with strong applicability to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a highly applicable corrosion-resistant sleeve to solve the problems mentioned in the background art, such as the friction between the metal conveying pipe and the anti-corrosion layer of the sleeve's inner wall when the conveying pipe is installed inside the anti-corrosion sleeve, which reduces the sleeve's corrosion resistance, and the fact that workers can only pick up two sleeves at a time due to inconsistent sleeve sizes. If multiple sleeves are stacked and picked up, it will damage the outer wall of the sleeve, affecting the sleeve's quality and reducing work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a highly adaptable corrosion-resistant sleeve, comprising a sleeve body, wherein a functional component body is installed inside the sleeve body, and there are four functional component bodies distributed symmetrically in a circle inside the sleeve body.

[0008] The functional component body has a connecting hole that penetrates the functional component body. A connecting shaft is installed in the connecting hole, and a roller is installed on the connecting shaft.

[0009] An outer sleeve is installed on the other side surface of the main body of the functional component. An adjustment hole is opened on the front surface of the outer sleeve. There are four adjustment holes, which are evenly distributed on the front surface of the outer sleeve. A fixing block is installed on the rear surface of the outer sleeve. A plug block is installed on the fixing block. The plug block is threaded.

[0010] The outer sleeve has a telescopic cavity inside, and an inner sleeve is installed inside the telescopic cavity. A spring cap is installed on the front surface of the inner sleeve near one side, and a spring cavity is opened inside the inner sleeve near the other side. A second spring is installed in the spring cavity, and a limit post is installed on the other end of the second spring. The limit post is a hollow design.

[0011] Preferably, a support plate is installed on the other side of the limiting post, and a movable groove is provided on the support plate. A locking slot is provided in the movable groove. There are two locking slots, which are symmetrically distributed in the movable groove.

[0012] Preferably, there are two inclined blocks installed in the movable groove, which are centrally symmetrically distributed in the movable groove. Each inclined block is equipped with a locking block located in a locking block slot. A clamping member is fixedly installed on the inclined block, and a rubber strip is installed on the clamping member. A spring is installed between the inclined blocks.

[0013] Preferably, the outer wall of the sleeve body is coated with a wear-resistant layer.

[0014] Preferably, the inner wall of the casing body is coated with a corrosion-resistant layer.

[0015] Preferably, the outer sleeve and the inner sleeve have the same length, and the length of the limiting post is one-third of the length of the inner sleeve.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. The rollers and functional components in this utility model can clamp the conveying pipe when installing it, and then push the conveying pipe into the sleeve using the insertion rod and rollers. This solves the problem that directly pushing metal conveying pipes will cause friction between the metal and the anti-corrosion layer of the inner wall of the sleeve, thereby reducing the corrosion resistance of the sleeve and the service life of the sleeve and the conveying pipe, and enhances the corrosion resistance of the sleeve.

[0018] 2. The outer sleeve and limiting post in this utility model allow for the sequential placement of sleeves of different sizes into the sleeve during transport by adjusting the spring cap on the inner sleeve. This enables the simultaneous transport of multiple sleeves without damaging the inner and outer walls of the sleeve, increasing the applicability of the device and improving work efficiency.

The sleeve body 1 has four functional component bodies 3 installed inside it. They are symmetrically distributed in a circle inside the sleeve body 1. The number of functional component bodies 3 can be increased or decreased according to the actual installation situation. At least two functional component bodies 3 are required.

[0026] A connecting hole 11 is provided on the main body 3 of the functional component. The connecting hole 11 passes through the main body 3 of the functional component. A connecting shaft 10 is installed in the connecting hole 11. A roller 9 is installed on the connecting shaft 10. The roller 9 is made of rubber.

[0027] An outer sleeve 6 is installed on the other side surface of the functional component body 3. An adjustment hole 23 is opened on the front surface of the outer sleeve 6. There are four adjustment holes 23, which are evenly distributed on the front surface of the outer sleeve 6. A fixing block 26 is installed on the rear surface of the outer sleeve 6. An insertion rod block 24 is installed on the fixing block 26. A thread 25 is opened on the insertion rod block 24. The function of the thread 25 is to facilitate the screw installation of the insertion rod on the insertion rod block 24, so as to facilitate the pushing and pulling operation of the functional component body 3.

[0028] The outer sleeve 6 has a telescopic cavity 12 inside, the length of which is slightly shorter than that of the inner sleeve 13. The inner sleeve 13 is installed inside the telescopic cavity 12. A spring cap 7 is installed on one side of the front surface of the inner sleeve 13. A spring cavity 14 is opened inside the inner sleeve 13 on the other side. The length of the spring cavity 14 is one-third of that of the inner sleeve 13. A second spring 22 is installed inside the spring cavity 14. A limit post 21 is installed at the other end of the second spring 22. The limit post 21 is a hollow design.

[0029] Furthermore, a support plate 5 is installed on the other side of the limiting post 21. The support plate 5 has a movable groove 15, and a locking groove 20 is provided in the movable groove 15. There are two locking grooves 20, which are symmetrically distributed in the movable groove 15.

[0030] Furthermore, two inclined blocks 16 are installed in the movable groove 15, which are centrally symmetrically distributed in the movable groove 15. A locking block 19 is installed on the inclined block 16, which is located in the locking block groove 20. A clamping member 8 is fixedly installed on the inclined block 16, and a rubber strip 18 is installed on the clamping member 8. The function of the rubber strip 18 is to increase the friction and to prevent friction between the clamping member 8 and the conveying pipe. A No. 1 spring 17 is installed between the inclined blocks 16.

[0031] Furthermore, the outer wall of the casing body 1 is coated with a wear-resistant layer 2, which is a thermally sprayed metal-ceramic wear-resistant coating. The thermally sprayed metal-ceramic wear-resistant coating has the characteristics of good coating toughness, stable chemical properties at high temperature, corrosion resistance, abrasive wear resistance, and wetting resistance.

[0032] Furthermore, the inner wall of the casing body 1 is coated with a corrosion-resistant layer 4, which is a polyvinyl chloride coating. The polyvinyl chloride coating has excellent corrosion resistance and high temperature resistance, and can resist the erosion of strong acids, strong alkalis and high temperature media.

[0033] Furthermore, the outer sleeve 6 and the inner sleeve 13 have the same length, and the length of the limiting post 21 is one-third of the length of the inner sleeve 13. The purpose of this setting is to effectively limit the conveying pipeline and lock the pipeline inside the sleeve body 1.

[0034] During use, firstly, the sleeve body 1 needs to be installed into the designated line. Then, using the functional component body 3, the spring cap 7 is adjusted according to the diameter of the conveying pipe. The spring cap 7 is placed into the corresponding adjustment hole 23. Then, the conveying pipe is placed in the clamping component 8. The first spring 17 will adaptively adjust according to the diameter of the conveying pipe. It should be noted that at least two functional component bodies 3 are required during use. After clamping the conveying pipe, the insert rod is screwed into the thread 25 on the insert rod block 24. Then, the insert rod is pushed to send the conveying pipe into the line. Inside the casing body 1, after reaching the designated position, the functional component body 3 is pulled out using the insertion rod. Without causing wear to the corrosion-resistant layer 4, the conveying pipeline is installed inside the casing body 1, ensuring the corrosion resistance of the casing body 1. Considering that workers need to use casings of different sizes during installation, the functional component body 3 can also be used to insert smaller casings into larger casings, thus stacking them. Multiple casings of different sizes can be taken at once without damaging the inner and outer walls of the casings. This is suitable for various casing sizes, increasing the applicability of the device.
