Abstract
Description
Technical Field
[0001] The present invention relates to the field of pipeline connection, and particularly to a fully self-anchored seismic-resistant flexible joint steel pipe. Background Art
[0002] At present, the fully self-anchored seismic-resistant flexible joint steel pipe is a new type of pipeline connection technology aimed at improving the seismic performance and explosion-proof leakage ability of the pipeline system. With the acceleration of the urbanization process, the complexity and importance of the underground pipeline network are increasing day by day. Especially in earthquake-prone areas, the safety and reliability of the pipeline system have become key issues. The fully self-anchored seismic-resistant flexible joint steel pipe can effectively cope with the impact of natural disasters such as earthquakes on the pipeline system through its unique design, ensuring the normal operation of urban infrastructure.
[0003] In the existing technology, one end of the flexible joint steel pipe is provided with a socket, and the other end is provided with a spigot. The spigot of one flexible joint steel pipe is inserted into the socket of an adjacent flexible joint steel pipe. A steel ring is sleeved at the opening position of the socket after insertion. The steel ring is provided with a deformation notch, and handles are installed on both sides of the steel ring corresponding to the deformation notch. A clamping groove for the steel ring to be clamped into is opened on the inner side wall of the socket; when the steel ring is to be clamped into the clamping groove, the construction worker first holds the handle by hand to reduce the diameter of the steel ring until the steel ring reaches the position of the clamping groove, and then releases the handle, so that the steel ring can be clamped into the clamping groove to complete the positioning.
[0004] In view of the above related technologies, in the actual construction process, many sections of flexible joint steel pipes need to be installed. Therefore, the construction workers need to hold the handle multiple times to deform the steel ring, which is likely to cause damage to the hands of the construction workers. Summary of the Invention
[0005] In order to reduce the harm to construction workers, the present application provides a fully self-anchored seismic-resistant flexible joint steel pipe.
[0006] The fully self-anchored seismic-resistant flexible joint steel pipe provided by the present application adopts the following technical solutions:
[0007] A fully self-anchored seismic-resistant flexible joint steel pipe includes a plurality of pipe bodies. One end of the pipe body is provided with a socket, and the other end is provided with a spigot. The spigot of one pipe body is inserted into the socket of an adjacent pipe body. A clamping groove is circumferentially extended and arranged at the corresponding opening of the socket. An arc-shaped steel ring is sleeved on the spigot. The arc-shaped steel ring is clamped to the socket through the clamping groove; the arc-shaped steel ring is provided with a deformation notch, and clamping holes are opened on both sides of the arc-shaped steel ring located at both ends of the deformation notch and facing outward; a convex platform is circumferentially protruded at the spigot, and the arc-shaped steel ring abuts against the side of the convex platform close to the pipe body.
[0008] By adopting the above technical solution, the arc steel ring is pre - sleeved at the socket and is on the side of the boss close to the pipe body. Then the socket is inserted into the socket. Next, the construction worker can directly insert the jaws of the pliers into the two clamping holes. Then, by tightly holding the handle of the pliers, according to the lever principle of the pliers, it is more labor - saving to drive the arc steel ring to deform. When the arc steel ring enters the corresponding clamping groove position in the socket, release the pliers, and the arc steel ring can spontaneously snap into the clamping groove, so that the socket can be stably in the socket. The above operation process can conveniently use the pliers tool to more labor - savingly drive the arc steel ring to deform, protect the hands of construction workers during the construction process, and greatly reduce the harm to construction workers.
[0009] Preferably, the ratio of the diameter of the clamping hole to the cross - sectional diameter of the arc steel ring is 1:3 - 1:4.
[0010] By adopting the above technical solution, the jaws of the pliers will not be difficult to insert due to the too - small clamping hole, nor will the strength of the arc steel ring at the corresponding clamping hole be unable to be guaranteed due to the too - large clamping hole.
[0011] Preferably, a rubber ring is sleeved on the inner side wall of the arc steel ring at the clamping hole.
[0012] By adopting the above technical solution, the friction force between the jaws of the pliers can be increased, and the stability of the pliers clamping the arc steel ring to deform can be improved.
[0013] Preferably, the arc steel ring includes an arc - shaped ring body and a pair of connecting sections. The two connecting sections are respectively detachably installed at both ends of the arc - shaped ring body. The clamping holes are opened on the connecting sections, and a deformation notch is formed between the two connecting sections.
[0014] By adopting the above technical solution, according to the situation during use, if the clamping hole is damaged, only the connecting section can be removed and a new connecting section can be replaced for normal use, improving the practicality.
[0015] Preferably, the socket includes a limiting section and an open - ended section. The limiting section and the open - ended section are arranged in sequence from the pipe body towards the direction away from the socket. The diameter of the limiting section is larger than the diameter of the pipe body. When the socket is inserted into the socket, the end of the socket away from the pipe body is within the limiting section. The open - ended section is in a trumpet shape, and the end with a larger opening of the open - ended section faces outwards.
[0016] By adopting the above technical solution, when the socket is inserted into the socket, the limiting section makes the socket stable at the socket. And the open - ended section can give space when the pipe body is bent due to vibration.
[0017] Preferably, an installation groove extends circumferentially at a position of the socket corresponding to the limiting section. A sealing rubber ring is sleeved at the position of the socket corresponding to the installation groove, and the outer ring of the sealing rubber ring abuts against the inner wall of the limiting section.
[0018] By adopting the above technical solution, the sealing performance of the connection between two adjacent pipe bodies can be improved. Moreover, due to the deformable property of the sealing rubber ring, the sealing performance is still maintained when the two adjacent pipe bodies are bent.
[0019] Preferably, a hook is arranged circumferentially at one end of the open section away from the limiting section, and the hook is bent inward to form the clamping groove.
[0020] By adopting the above technical solution, the clamping groove is formed by bending the open section at one end away from the limiting section itself, which has a simple structure and is convenient for processing.
[0021] Preferably, the cross-section of the convex platform is arc-shaped.
[0022] By adopting the above technical solution, when the socket is inserted into the socket, it is more smooth, and the stress concentration of the socket can be reduced, and the strength can be improved.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. First, the arc steel ring is sleeved at the socket and is located on the side of the convex platform close to the pipe body. Then, the socket is inserted into the socket. Next, the construction worker can directly insert the jaws of the pliers into the two clamping holes. Then, by tightly holding the handle of the pliers, according to the lever principle of the pliers, it is more labor-saving to drive the arc steel ring to deform. When the arc steel ring enters the position corresponding to the clamping groove in the socket, release the pliers, and the arc steel ring can spontaneously snap into the clamping groove, so that the socket can be stably fixed in the socket; the above operation process can conveniently use the pliers tool to more labor-savingly drive the arc steel ring to deform, which can protect the hands of the construction workers during the construction process and greatly reduce the harm to the construction workers;
[0025] 2. The jaws of the pliers will not be difficult to insert due to the too small clamping holes, nor will the strength of the arc steel ring corresponding to the clamping holes be unable to be guaranteed due to the too large clamping holes;
[0026] 3. Due to the deformable property of the sealing rubber ring, the sealing performance is still maintained when the two adjacent pipe bodies are bent. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0035] The following further elaborates on the present application in conjunction with the attached Figures 1-6 to make a further detailed description of the present application.
[0036] Embodiment 1 of the present application discloses a fully self-anchored seismic-resistant flexible joint steel pipe.
[0037] Embodiment 1
[0038] Referring to Figure 1 , the flexible joint steel pipe includes a plurality of pipe bodies 1. The pipe bodies 1 are cylindrical. One end of the pipe body 1 is provided with a socket 2, and the other end is provided with a spigot 3. The socket 2 and the pipe body 1, as well as the spigot 3 and the pipe body 1, are integrally formed. The spigot 3 of one pipe body 1 is inserted into the socket 2 of an adjacent pipe body 1, and there is a gap between the spigot 3 and the socket 2.
[0039] Referring to Figure 2 , Figure 3 and Figure 4, the socket 2 includes a limiting section 21 and an open section 22, which are integrally formed between the limiting section 21 and the open section 22. The limiting section 21 and the open section are arranged in sequence from the pipe body 1 in the direction away from the socket 3 (described by a single pipe body 1). The diameter of the limiting section 21 is larger than that of the pipe body 1, and the diameter of the socket 3 is larger than that of the pipe body 1. When the socket 3 is inserted into the socket 2, the end of the socket 3 away from the pipe body 1 is located within the limiting section 21; the open section 22 is in a flared shape, and the end with a larger opening of the open section 22 is arranged outward. A hook 23 is arranged along the circumferential direction at the end of the open section 22 away from the limiting section 21. The hook 23 is bent inward in an arc shape to form a clamping groove 24 together with the open section 22; an arc steel ring 4 is sleeved on the socket 3, and the arc steel ring 4 is clamped to the socket 2 through the clamping groove 24. The arc steel ring 4 is provided with a deformation notch 41, and clamping holes 42 are opened on both sides of the arc steel ring 4 located at both ends of the deformation notch 41 and facing outward; thus, tools such as pliers can be inserted into the clamping holes 42, so that after the arc steel ring 4 is deformed and enters the position corresponding to the clamping groove 24, the arc steel ring 4 can be released and smoothly snapped into the clamping groove 24; the ratio of the diameter of the clamping hole 42 to the cross-sectional diameter of the arc steel ring 4 is 1:3 - 1:4. In this embodiment, this ratio is 1:3; a rubber ring (not shown in the figure) is sleeved on the inner side wall of the clamping hole 42.
[0040] A convex platform 31 is protruded along the circumferential direction at the socket 3. The cross-section of the convex platform 31 is in an arc shape. The side of the arc steel ring 4 away from the hook 23 abuts against the side of the convex platform 31 close to the pipe body 1; thereby, the overall anti-pulling bearing capacity of the flexible joint steel pipe can be improved.
[0041] Refer to Figure 3 and Figure 4 , an installation groove 32 extends along the circumferential direction on the outer side wall of the end of the socket 3 away from the pipe body 1. The installation groove 32 is formed by the socket 3 being concave. A sealing rubber ring 33 is sleeved in the socket 3 corresponding to the installation groove 32. A part of the sealing rubber ring 33 is located within the installation groove 32, and the other part is located outside the installation groove 32 and abuts against the inner side wall of the limiting section 21, so as to still achieve a sealing effect when the interface is bent.
[0042] The implementation principle of Embodiment 1 is as follows: First, the arc steel ring 4 is sleeved on the socket 3 and is located on the side of the convex platform 31 close to the pipe body 1. Then, the socket 3 is inserted into the socket 2. Next, the construction worker can directly insert the jaws of the pliers into the two clamping holes 42, and then by tightly holding the handle of the pliers, according to the lever principle of the pliers, it is more labor-saving to drive the arc steel ring 4 to deform. When the arc steel ring 4 enters the position corresponding to the clamping groove 24 in the socket 2, the pliers are released, and the arc steel ring 4 can spontaneously snap into the clamping groove 24, thereby completing the flexible connection between adjacent pipe bodies 1.
[0043] Embodiment 2
[0044] Refer toFigure 5 and Figure 6 , the difference between this embodiment and Embodiment 1 is that the arc steel ring 4 includes an arc-shaped ring body 43 and a pair of connecting sections 44. The two connecting sections 44 are respectively threadedly installed at both ends of the arc-shaped ring body 43, and the two connecting sections 44 are located on the same straight line; the clamping holes 42 are formed in the connecting sections 44, and a deformation notch 41 is formed between the two connecting sections 44.
[0045] The implementation principle of Embodiment 2 is that when the connecting section 44 needs to be replaced during use, the connecting section 44 can be directly screwed out for replacement without replacing the entire arc steel ring 4.
[0046] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
