Description

Technical Field

[0001] This invention relates to the field of anchoring interface technology, and more particularly to an anchoring interface for ductile iron pipes that is easy to fix. Background Technology

[0002] Ductile iron pipe is a type of cast iron, an alloy of iron, carbon, and silicon, possessing the essential properties of iron and the performance of steel. Annealed ductile iron pipe exhibits good mechanical properties, excellent corrosion resistance, and good ductility, and is mainly used for water supply, gas transmission, and oil transportation in municipal and industrial enterprises.

[0003] The installation and use of ductile iron pipe joints is currently quite complicated. First, a sealing ring is embedded in the outside of the ductile iron pipe end, and then it is inserted into the joint pipe. To prevent the connection between the ductile iron pipe and the joint pipe from falling off, the ductile iron pipe and the joint pipe are then welded together to create a gap. The welding operation requires professional personnel. If the operation is carried out in a limited space, the welding quality is difficult to guarantee, and the installation is troublesome. Furthermore, it increases the difficulty of replacing the ductile iron pipe or the joint pipe when needed.

[0004] In view of this, the inventors of this application have invented an anchoring interface for easily fixed ductile iron pipes. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing an easy-to-fix ductile iron pipe anchoring interface.

[0006] The present invention solves the above-mentioned technical problems through the following technical means: a ductile iron pipe anchoring interface that is easy to fix, including an interface pipe, wherein annular grooves are opened at both ends of the interface pipe, and anchoring sleeves are fixedly fitted at both ends of the interface pipe, wherein the inner side of the anchoring sleeve is sealed and connected to the outer side of the ductile iron pipe and the outer side of the interface pipe port, respectively.

[0007] Furthermore, the anchoring sleeve includes a lower half ring and an upper half ring, which are arranged opposite to each other. The lower half ring is located at the bottom surface of the interface pipe port, and the upper half ring is located at the top surface of the interface pipe end. Side strips are fixed to both sides of the lower half ring and both sides of the upper half ring. Adjacent side strips are fixed together by a number of connecting bolts. The connecting bolts pass through the adjacent side strips in sequence, and a nut is screwed onto the other end of the connecting bolt.

[0008] Furthermore, sealing gaskets are fixed to the inner sides of the lower half ring and the upper half ring, respectively, in contact with the interface pipe and the ductile iron pipe.

[0009] Furthermore, the groove is a sealed casting cavity formed by the sealing gasket, the outer side of the ductile iron pipe and the inner side of the interface pipe. The casting cavity contains a binder. The outer side of the interface pipe port is provided with a casting port that communicates with the casting cavity. The surface of the anchor sleeve is also provided with a through hole corresponding to the position of the casting port.

[0010] Furthermore, the binder is epoxy resin.

[0011] Furthermore, the through hole is formed on the surface of the upper half ring.

[0012] Furthermore, a correction component is provided at the bottom of the anchor sleeve. By rotating the correction component, the extension and retraction of the extension and retraction end of the correction component can be adjusted, thereby adjusting the horizontal height of both ends of the interface tube.

[0013] Furthermore, the correction component includes a pad block disposed at the bottom of the lower half ring, a top post fixed to the bottom surface of the pad block, a threaded post passing through the bottom surface of the top post, the threaded post being screwed into the top post by threads, the bottom end of the threaded post extending to the outside of the top post, a base being disposed at the bottom end of the threaded post, and the bottom end of the threaded post being rotatably connected to the base.

[0014] Furthermore, a handle is fixed to the outer surface of the threaded column, a pressure bearing is provided at the bottom end of the threaded column, the bottom end of the threaded column is fixed to the top surface of the pressure bearing, and the pressure bearing is embedded in the base.

[0015] Furthermore, a distance measuring module is fixedly installed at the bottom of the anchor sleeve. The distance measuring module is used to monitor the distance between the two ends of the interface pipe and the ground, and sends the obtained distance value to the server. If the difference between the distance between the two ends of the interface pipe and the ground is zero, no maintenance command is generated; if the difference between the distance between the interface pipe and the ground is greater than zero, a maintenance command is generated, and the installation position information of the corresponding interface pipe is obtained. The maintenance command and the installation position information of the corresponding interface pipe are sent to the mobile device for display.

[0016] The beneficial effects of this invention are:

[0017] 1. The present invention relates to an anchoring interface for ductile iron pipes. First, a sealing ring is fitted onto the outside of the ductile iron pipe port and inserted into the groove. Then, the lower half ring is placed at the bottom of the interface pipe port, and the upper half ring is placed at the top of the interface pipe port. The lower half ring is positioned opposite the bottom of the upper half ring. Then, the lower half ring and the upper half ring are fixed together by connecting bolts and nuts. Installation and disassembly are convenient. Under the action of the lower half ring, the upper half ring, and the sealing gasket, the connection and fixing area between the ductile iron pipe and the interface pipe is increased, thereby improving the sealing performance and connection strength of the connection between the ductile iron pipe and the interface pipe.

[0018] 2. The ductile iron pipe anchoring interface of the present invention has a casting cavity set in the groove, and through holes and casting ports on the surface of the anchor sleeve. The surface of the anchor sleeve also has through holes corresponding to the positions of the casting ports. The bonding agent is injected into the casting cavity through the casting pipe. After the bonding agent solidifies, it can be disassembled by simply heating the bonding agent. The installation and disassembly are convenient, which further improves the connection firmness and sealing performance between the ductile iron pipe and the interface pipe.

[0019] 3. In the ductile iron pipe anchoring interface of the present invention, when the installation position of the interface pipe settles, if one end of the interface pipe sinks, the threaded column at the sinking end of the interface pipe is rotated so that the bottom end of the threaded column extends out, increasing the amount of expansion and contraction. The sinking end of the interface pipe is then raised accordingly, ensuring that both ends of the interface pipe and the ductile iron pipe are always on the same horizontal plane, further ensuring the sealing of the connection between the interface pipe and the ductile iron pipe.

[0020] 4. In the ductile iron pipe anchoring interface of this invention, the distance measuring module is used to monitor the distance between the two ends of the interface pipe and the ground, and sends the obtained distance value to the server. If the difference between the distance between the interface pipe and the ground is greater than zero, a maintenance command is generated, and the installation position information of the corresponding interface pipe is obtained. The maintenance command and the installation position information of the corresponding interface pipe are sent to the mobile device for display. According to the installation position of the interface pipe, the maintenance personnel go to the maintenance location and adjust the height of the two ends of the interface pipe to ensure that the two ends of the interface pipe and the end of the interface pipe are on the same horizontal plane, further ensuring the connection and sealing of the interface pipe and the ductile iron pipe.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0028] Example 1

[0029] Please see Figure 3 As shown, the easy-to-fix ductile iron pipe anchoring interface described in this embodiment includes an interface pipe 1. The interface pipe 1 is hollow inside and open at both ends, with the two ends communicating with its interior. Both ends of the interface pipe 1 have annular grooves 11. When the ductile iron pipe is inserted into both ends of the interface pipe 1, the end of the ductile iron pipe abuts against the groove 11. A sealing ring 7 is embedded on the outside of the ductile iron pipe port. The ductile iron pipe is sealed and connected in the groove 11 through the sealing ring 7, thus completing the sealed connection between the ductile iron pipe and the interface pipe 1.

[0030] To enhance the connection between the ductile iron pipe and the interface pipe 1, anchor sleeves 2 are fixedly fitted at both ends of the interface pipe 1. The inner side of the anchor sleeve 2 is sealed to the outer side of the ductile iron pipe and the outer side of the port of the interface pipe 1, respectively, as shown in the figure. Figure 1 As shown.

[0031] Please see Figure 1 , 2 As shown, the anchoring sleeve 2 includes a lower half-ring 21 and an upper half-ring 22. The lower half-ring 21 and the upper half-ring 22 are arranged opposite to each other. The lower half-ring 21 is located at the bottom surface of the port of the interface pipe 1, and the upper half-ring 22 is located at the top surface of the end of the interface pipe 1. Side strips 23 are fixed to both sides of the lower half-ring 21 and both sides of the upper half-ring 22. Adjacent side strips 23 are fixed together by several connecting bolts 24. The connecting bolts 24 pass through the adjacent side strips 23 in sequence, and the other end of the connecting bolts 24 is screwed with a nut. Sealing gaskets 5 are fixed to the inner side of the lower half-ring 21 where it contacts the interface pipe 1 and the ductile iron pipe, and to the inner side of the upper half-ring 22 where it contacts the interface pipe 1 and the ductile iron pipe, respectively. Figure 4 As shown, the anchor sleeve 2 is sealed and fixed to the interface pipe 1 and the ductile iron pipe respectively under the action of the sealing gasket 5 and the connecting bolt 24.

[0032] To further improve the sealing performance of the connection between the interface pipe 1 and the ductile iron pipe, a sealed casting cavity 8 is formed within the groove 11 by the sealing gasket 5, the outer side of the ductile iron pipe, and the inner side of the interface pipe 1. The casting cavity 8 is connected to the groove 11. A casting port 4, which communicates with the casting cavity 8, is opened on the outer side of the port of the interface pipe 1. A through hole corresponding to the position of the casting port 4 is also opened on the surface of the anchor sleeve 2. The through hole is opened on the surface of the upper half ring 22, such as... Figure 3 As shown.

[0033] In use, the casting pipe 3 passes through the through hole on the surface of the anchor sleeve 2 and the casting port 4 in sequence. Then, the bonding agent, such as epoxy resin, is injected into the casting cavity 8 through the casting pipe 3. The bonding agent is injected into the casting cavity 8 in multiple rapid injections to facilitate the gradual discharge of air from the casting cavity 8. After the epoxy resin solidifies, the spherical cast iron pipe and the interface pipe 1 are tightly connected together.

[0034] To further enhance the connection strength between the ductile iron pipe and the interface pipe 1, several annular grooves 6 are opened on both the inner and outer sides of the ductile iron pipe in the casting cavity 8 and on the inner wall of the interface pipe 1 in the casting cavity 8. After the binder solidifies, the connection strength between the ductile iron pipe and the interface pipe 1 is further enhanced.

[0035] In use, first, the sealing ring 7 is placed on the outside of the ductile iron pipe port and inserted into the groove 11. Then, the lower half ring 21 is placed at the bottom of the interface pipe 1 port, and the upper half ring 22 is placed at the top of the interface pipe 1 port. The lower half ring 21 is positioned opposite the bottom of the upper half ring 22. Then, the lower half ring 21 and the upper half ring 22 are fixed together by the connecting bolts 24 and nuts. Installation and disassembly are convenient. Under the action of the lower half ring 21, the upper half ring 22 and the sealing gasket 5, the connection and fixing area between the ductile iron pipe and the interface pipe 1 is increased, which improves the connection sealing and connection strength between the ductile iron pipe and the interface pipe 1.

[0036] Example 2

[0037] Please see Figure 3 As shown, this embodiment is a further improved design based on embodiment one. When the position of the ductile iron pipe and the interface pipe 1 settles, the ductile iron pipe and the interface pipe 1 will not be on the same plane, resulting in uneven force on the sealing ring 7 and the sealing gasket 5. Over time, this will eventually lead to gaps in the connection between the ductile iron pipe and the interface pipe 1, resulting in leakage of the medium being transported inside the ductile iron pipe.

[0038] An anchor sleeve 2 is equipped with a correction component 9 at the bottom. By rotating the correction component 9, the amount of extension and retraction of the extension and retraction end of the correction component 9 can be adjusted, thereby adjusting the horizontal height of both ends of the interface pipe 1.

[0039] Please see Figure 3As shown, the correction component 9 includes a pad 96 disposed at the bottom of the lower half ring 21. A top post 91 is fixed on the bottom surface of the pad 96. A threaded post 92 passes through the bottom surface of the top post 91. The threaded post 92 is screwed into the top post 91 by threads. The bottom end of the threaded post 92 extends to the outside of the top post 91. A base 93 is disposed at the bottom end of the threaded post 92. The bottom end of the threaded post 92 is rotatably connected to the base 93.

[0040] When the installation position of interface pipe 1 settles, if one end of interface pipe 1 sinks, rotate the threaded post 92 at the sinking end of interface pipe 1 to extend the bottom end of threaded post 92, increasing the amount of extension and retraction. Then, raise the sinking end of interface pipe 1 accordingly to ensure that both ends of interface pipe 1 and ductile iron pipe are always on the same horizontal plane, further ensuring the sealing of the connection between interface pipe 1 and ductile iron pipe.

[0041] To facilitate rotation of the threaded post 92, a handle 94 is fixed to the outer surface of the threaded post 92, and a pressure bearing 95 is provided at the bottom end of the threaded post 92. The bottom end of the threaded post 92 is fixed to the top surface of the pressure bearing 95. Figure 3 As shown, the pressure bearing 95 is embedded in the base 93.

[0042] Example 3

[0043] To facilitate timely detection of settlement at installation locations by maintenance personnel, this embodiment further improves upon the design of Embodiment 2. The difference is that a distance measuring module 10 is fixedly installed at the bottom of the anchor sleeve 2. The distance measuring module 10 is used to monitor the distance between the two ends of the interface pipe 1 and the ground, and sends the obtained distance value to the server 12. If the difference between the distance between the two ends of the interface pipe 1 and the ground is zero, no maintenance command is generated; if the difference between the distance between the interface pipe 1 and the ground is greater than zero, a maintenance command is generated, and the installation position information of the corresponding interface pipe 1 is obtained. The maintenance command and the installation position information of the corresponding interface pipe 1 are then sent to the mobile device 13 for display.

[0044] The mobile device 13 is carried by maintenance personnel. The maintenance personnel go to the maintenance location according to the installation position of the interface tube 1 and adjust the height of both ends of the interface tube 1 to ensure that both ends of the interface tube 1 and the end of the interface tube 1 are on the same horizontal plane, further ensuring the sealing of the connection between the interface tube 1 and the ductile iron pipe. The ranging module 10 includes a ranging sensor, which measures the distance between both ends of the interface tube 1 and the bottom surface.

[0045] The ranging module 10, server 12, and mobile device 13 are all connected wirelessly.
