It has been widely used in many fields and industries such as municipal construction, petrochemical industry, water conservancy and irrigation, fire safety, submarine drainage, pressure water supply, aquaculture, sewage treatment, etc. in my country.

[0003] The joints of continuously wound FRP pipes usually use flexible connections, that is, they are connected using integral rubber sealing ring sleeve joints. In actual construction and installation, this type of connection method may cause problems such as excessive deflection angles between pipes at the joints and inconsistent vertical deformation of pipes at both ends of the joints when improperly constructed, which can easily cause problems such as joint leakage and water seepage.

[0004] In addition, the pipeline can be moved in the axial direction of the pipeline. When the temperature changes, the length of the pipeline has a certain amount of expansion and contraction; or when the pipeline is subjected to axial force at the location of the pipeline fittings; or in special circumstances, such as the seabed and complex locations, this sleeve joint is prone to falling off. At present, the continuously wound FRP pipe is generally outsourced at this location, with a clamping ring installed on the outside or a hole drilled on the pipe to fix the lock on the pipe. However, this method is time-consuming and labor-intensive, and the operation is troublesome, or there are hidden dangers in the pipeline. Therefore, further optimization is needed to improve the problems of conventional sleeve joints. Summary of the invention

[0020] Preferably, the two calibration rods are arranged symmetrically to each other, and the distance between the two calibration rods corresponds to the distance between the lockers on both sides of the bottom of the first pipe or the second pipe.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention provides an integral rubber sealing ring anti-overlimit sleeve joint, so that it can withstand the action of axial force and limit the pipe from being pulled out of the interface. When the external temperature changes, the interface can withstand a certain amount of expansion and contraction. During construction, by adjusting the positions of the bolt pull rod and the nut, the deflection angle between the pipes at the joint can be effectively controlled to avoid the situation where the deflection angle of the joint is not properly controlled during construction. At the same time, in actual applications, by using multiple integral rubber sealing ring anti-overlimit sleeve joints, it is possible to effectively prevent the deflection angle between the pipes at the joint from being too large, ensure the consistency of vertical deformation at both ends of the sleeve joint, and prevent the pipe from being pulled out of the sleeve joint or the pipe from expanding, lengthening, squeezing and damaging, thereby reducing the use of elbow piers.

[0023] The setting of the winding groove and the glass fiber resin, that is, the glass fiber resin can be wound and impregnated inside the winding groove, so that after it is cured and formed, the degree of the pipe connection port can be increased, and the vertical deformation difference between the two ports can be reduced during the pipe installation backfilling process, which greatly reduces the leakage problem caused by inconsistent construction backfilling.

[0024] The setting of the locker, the bolt pull rod, the first nut and the second nut, through the setting of the locker, replaces the traditional bolt rope installation, avoids the rope from being easily deformed, easy to slide during installation, which is not conducive to the occurrence of installation situations, and requires the elbow to be turned through the joint. The installation limit screw nut can be installed to limit the position before installation, and the installation can be adjusted to the specified angle. The joint angle is turned accurately and reliably, and when the foundation settles unevenly, the first nut and the second nut on the upper side are compressed, and the bolt pull rod is in a compressed state to avoid the upper end faces of the two pipes from colliding, and the first nut and the second nut on the lower side are compressed, and the bolt pull rod is in a stretched state to avoid the lower end faces of the two pipes from being pulled out of the sleeve joint. Similarly, it can also prevent places with high water levels and avoid local floating pipes, thereby ensuring the anti-overlimit effect and ensuring the safety of the pipeline sleeve joint.

[0025] The integral rubber sealing ring anti-overrun sleeve joint provided in the present invention is easy to realize during the manufacturing process, avoiding the time-consuming and labor-intensive problems of outsourcing the sleeve joint and installing a clamping ring on the outside, and also avoiding the late hidden dangers of opening a hole in the pipeline.

[0026] The setting of the supporting assembly, that is, the ball disposed on the upper end of the supporting seat, can flexibly realize the rotation adjustment of the first pipe and the second pipe by cooperating with the rolling effect of the ball when completing the supporting activities of the first pipe and the second pipe, so that the locker disposed outside the first pipe and the second pipe can be quickly rotated and adjusted and relative to the left and right, thereby ensuring the subsequent locking and docking efficiency.

[0027] The calibration mechanism is set up, and under the drive of the servo motor, it can drive the push bar and the calibration rod to move. After the movement, the calibration rod can be extended between the locks on both sides of the bottom of the pipe. The locks on both sides are limited by the two calibration rods, so that the pipe cannot rotate, and the locks of the first pipe and the second pipe are made to correspond to each other. After the second pipe is subsequently docked with the first pipe, the locks are convenient to dock, which is convenient for the subsequent installation and locking of the bolt pull rod, thereby improving the construction efficiency.

[0040] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0041] See also Figure 1-Figure 7 The present invention provides an integral rubber sealing ring anti-overlimit sleeve joint and a construction method thereof, comprising a first pipe 1, a second pipe 2, an integral rubber sealing ring sleeve joint 3, a locking device, a bolt pull rod 8, a first nut 9 and a second nut 10, wherein the first pipe 1 and the second pipe 2 are arranged correspondingly, an integral rubber sealing ring sleeve joint 3 is arranged between the first pipe 1 and the second pipe 2, a locking device for limiting the integral rubber sealing ring sleeve joint 3 is installed on the outer sides of the first pipe 1 and the second pipe 2, and the locking devices on the first pipe 1 and the second pipe 2 are connected by a bolt pull rod 8, and the two sides of the bolt pull rod 8 are locked with the locking device by the first nut 9 and the second nut 10, and four locking devices are arranged on the first pipe 1 and the second pipe 2, and the four locking devices are evenly distributed at 90 degrees, and the angle with the vertical plane is 45 degrees, so as to better lock and limit the integral rubber sealing ring sleeve joint 3 and prevent the integral rubber sealing ring sleeve joint 3 from loosening.

[0042] The locking device comprises vertical plates 4 respectively arranged on the outside of the first pipe 1 and the second pipe 2, and a limiting retaining ring 5 installed on the outside of the first pipe 1 and the second pipe 2 and connected to the vertical plates 4. By setting the limiting retaining ring 5, the vertical plates 4 at each location can be effectively and firmly connected with the outer ends of the first pipe 1 and the second pipe 2. A winding groove 6 is provided between the limiting retaining ring 5 and the vertical plates 4, and glass fiber resin 7 is wound inside the winding groove 6. The glass fiber resin 7 is wound in the winding groove 6 of the vertical plate 4, so that the locking device can be firmly locked on the outside of the pipe.

[0043] Among them, the vertical plates 4 are equidistantly installed in a circular trajectory along the outer sides of the first pipe 1 and the second pipe 2, and locking holes are provided on the upper part of each side vertical plate 4. The locking holes are used for connecting the bolt rod 8 with the vertical plate 4, and the bolt rod 8 and the vertical plate 4 are locked by the first nut 9 and the second nut 10 to achieve the anti-overlimit effect.

[0044] A convex end is provided at the middle end of the integral rubber sealing ring sleeve joint 3, and the convex end provided at the middle end of the integral rubber sealing ring sleeve joint 3 is connected to the openings of the first pipe 1 and the second pipe 2. Through the arrangement of the integral rubber sealing ring sleeve joint 3, it is possible to effectively prevent the deflection angle between the pipes at the joint from being too large, and it is also possible to improve the rigidity of the pipes at both ends of the joint, ensure the consistency of the vertical deformation at both ends of the sleeve joint, and prevent the pipe from being pulled out of the sleeve joint or being squeezed and damaged due to the expansion and lengthening of the pipe.

[0045] It should be noted that the integral rubber sealing ring sleeve joint 3 is easy to realize in the manufacturing process, avoiding the time-consuming and labor-intensive problem of outsourcing the sleeve joint and installing the clamp ring on the outside, and also avoiding the late hidden dangers of opening holes on the pipeline. At the same time, it can withstand the axial force, can limit the pipeline from being pulled out of the interface, and when the external temperature changes, the interface can withstand a certain amount of expansion and contraction, such as Figure 4 and Figure 5 As shown;

[0046] Secondly, the integral rubber sealing ring sleeve joint 3 can effectively control the deflection angle between the pipes at the joint by adjusting the positions of the first nut 9 and the second nut 10 provided on the outer side of the bolt pull rod 8 during construction, so as to avoid the occurrence of the situation that the deflection angle is not properly controlled during construction. Figure 6 In actual engineering applications, continuous borrowing can be adopted, using multiple integral rubber sealing ring sleeve joints 3 to reduce the use of elbows and the setting of elbow piers, which has significant economic benefits such as Figure 7 ;

[0047] In the integral rubber sealing ring anti-overlimit sleeve joint of the present application, the winding groove 6 formed between the limit retaining ring 5 and the two sides of the vertical plate 4 is wound with the impregnated glass fiber resin 7, so that the glass fiber resin 7 is solidified and formed, thereby increasing the rigidity of the pipe connection port, and reducing the vertical deformation difference between the two ports during the pipe installation backfilling process, greatly reducing the leakage problem caused by inconsistent construction backfilling.

[0048] See also Figure 8 The present invention provides a construction method of an integral rubber sealing ring anti-overrun sleeve joint, comprising the following steps:

[0049] S1: Connect the limit ring 5 of the locking device to the outer side of the first pipe 1 or the second pipe 2, so that the locking device fits the outer side of the first pipe 1 or the second pipe 2;

[0050] S2: The first pipe 1 or the second pipe 2 with the locking device is installed on the external rotating mechanism to rotate the first pipe 1 or the second pipe 2. During the rotation, the prestressed glass fiber resin 7 is soaked and then wound into the winding groove 6 of the locking device. After being cured and formed, the locking device is fastened to the first pipe 1 and the second pipe 2.

[0051] S3: During installation, the first pipe 1 and the second pipe 2, to which the integral rubber sealing ring sleeve joint 3 is pre-installed, are hoisted to the upper ends of the first supporting assembly 11 and the second supporting assembly 12 respectively, and the position angles of the four lockers on the upper parts of the first pipe 1 and the second pipe 2 are adjusted by the first supporting assembly 11 and the second supporting assembly 12, so that the positions of the lockers installed on the upper parts of the first pipe 1 and the second pipe 2 correspond to each other;

[0052] S4: When the positions of the lockers on the first pipe 1 and the second pipe 2 correspond to each other, the second pipe 2 is inserted into the integral rubber sealing ring sleeve joint 3 on the first pipe 1, and then the M24 threaded rod 8 with a rod length of 850m is selected, and the second nut 10 is screwed into the left side of the threaded rod 8 with a screwing distance of 180mm, and the second nut 10 is screwed into the right side with a screwing distance of 110mm, and then the bolt rod 8 with the limit nut installed is obliquely inserted into the lock hole of the vertical plate 4 of the locker on the first pipe 1 on the left side, so that the right side of the bolt rod 8 can pass through the lock hole of the vertical plate 4 of the locker on the second pipe 2, and the bolt rod 8 is moved along the direction of the second pipe 2, so that the second nuts 10 on the left and right sides of the threaded rod 8 are respectively in contact with the vertical plate 4 of the locker to reach the limit insertion state, and then the two first nuts 9 are respectively screwed into the outer rod body of the vertical plate 4 of the locker on the first pipe 1 and the second pipe 2 at both ends of the threaded rod 8, and screwed into the over-limit reserved position for construction or foundation settlement. When the pipe deflects, after installing the two first nuts 9, screw the two second nuts 10 into the direction of the overall rubber sealing ring sleeve joint 3 for a certain distance, about 10 mm, to allow the pipe to have a certain displacement into the overall rubber sealing ring sleeve joint 3. From then on, the docking work of a pair of lockers is completed, and the other three sets of lockers in the three directions of the ring are installed in the same way. After all the installation is completed, thread glue needs to be injected into each limit nut to prevent the nut from loosening;

[0053] S5: The first supporting assembly 11 is withdrawn from the first pipeline 1 and arranged to the set position of the next pipeline to be docked, and the second supporting assembly 12 is moved to the second pipeline 2 to the position to be docked with the next pipeline.

[0054] In which, the glass fiber resin 7 in step S2 is circumferentially wound along the first pipe 1 or the second pipe 2, and the winding thickness of the glass fiber resin 7 is not less than 25% of the wall thickness of the first pipe 1 or the second pipe 2. In this way, after the glass fiber resin 7 is wound and solidified, the locking device can be efficiently fixed, the problem of looseness during installation and use can be avoided, and the tightness of the subsequent double pipe docking can be improved.

[0055] See also Fig. 9In step S4, the first supporting component 11 includes a supporting seat 111 placed at the bottom of the first pipe 1. The upper end of the supporting seat 111 is arranged in a semi-arc-shaped mouth shape, which is adapted to the bottom of the first pipe 1 and the second pipe 2. A ball 112 is arranged at the upper end of the supporting seat 111. The ball 112 is equidistantly arranged at seven locations along the semi-arc-shaped mouth. Through the arrangement of multiple ball 112, the docking rotation adjustment activities of the first pipe 1 or the second pipe 2 can be coordinated. A calibration mechanism 113 is installed on one side of the supporting seat 111. Through the arrangement of the calibration mechanism 113, the first pipe 1 and the second pipe 2 can be quickly symmetrical on the left and right, and then docked. It should be noted that the overall structure of the first supporting component 11 and the second supporting component 12 are consistent, and the first supporting component 11 and the second supporting component 12 are placed opposite to each other on the left and right, ensuring that the first supporting component 11 and the second supporting component 12 correspondingly arranged at the lower ends of the first pipe 1 and the second pipe 2 can achieve stable supporting rotation adjustment and rapid calibration and alignment.

[0056] See also Figure 10-11 The calibration mechanism 113 includes a fixed plate 1131, a servo motor 1132, a rotating block 1133, a rotating arm 1134, a spring 1135, a slider 1136, a moving rod 1137, a guide rod 1138, a docking plate 1139, a push bar 11310 and a calibration rod 11311. One end of the fixed plate 1131 is installed on one side of the supporting seat 111, and the servo motor 1132 is installed on the rear side of the other end. The front end of the fixed plate 1131 is rotatably connected to the rotating block 1133, and the rotating block 1133 is connected to the output end of the servo motor 1132. The rotating arm 1134 is movably inserted inside the rotating block 1133, and the rotating arm 1134 is externally A spring 1135 is provided on the side, one end of the spring 1135 is connected to the rotating block 1133, and the other end is against the head of the rotating arm 1134. The elastic force of the spring 1135 can ensure the stability of the self-telescopic activity of the rotating arm 1134. The head of the rotating arm 1134 is rotatably connected to the rear side of the slider 1136. The slider 1136 is slidably mounted on the moving rod 1137. The upper end sleeve of the moving rod 1137 is slidably mounted on the guide rod 1138, and the top of the upper end sleeve of the moving rod 1137 is connected to a docking plate 1139. The top of the docking plate 1139 is connected to the middle part of the push strip 11310, and calibration rods 11311 are installed at both ends of the push strip 11310.

[0057] Among them, the two calibration rods 11311 are arranged symmetrically with each other on the left and right, and the distance between the two calibration rods 11311 corresponds to the distance between the locks on both sides of the bottom of the first pipe 1 or the second pipe 2, which is convenient for the locks on both sides of the bottom of the first pipe 1 or the second pipe 2 to be quickly positioned, and then convenient for the locks on both sides of the bottom of the first pipe 1 or the second pipe 2 to be quickly docked and locked.

[0058] Working principles of the first supporting assembly 11 and the second supporting assembly 12:

[0059] After the installation of the outer locking devices of the first pipe 1 and the second pipe 2 and the winding and curing of the glass fiber resin 7 are completed, the first pipe 1 and the second pipe 2 on which the integral rubber sealing ring sleeve joint 3 is installed in advance can be hoisted to the upper ends of the first supporting assembly 11 and the second supporting assembly 12, respectively, and hoisted to the upper ends of the supporting seats 111 of the first supporting assembly 11 and the second supporting assembly 12, so as to realize the supporting placement of the first pipe 1 and the second pipe 2 in advance. In order to ensure that the locking devices provided on the outside of the first pipe 1 and the second pipe 2 can be aligned left and right to ensure the rapid subsequent connection, the first pipe 1 and the second pipe 2 can be pushed manually, and the first pipe 1 or the second pipe 2 can be smoothly rotated and adjusted through the ball 112 provided at the semi-arc-shaped opening provided at the upper end of the supporting seat 111, so as to realize the corresponding rotation adjustment of the first pipe 1 and the second pipe 2;

[0060] When the first pipe 1 and the second pipe 2 are rotated to the appropriate positions, the servo motor 1132 can be driven to drive the rotating block 1133 provided on the front side of the fixed plate 1131 to rotate. When the rotating block 1133 rotates, the rotating arm 1134 inserted into the rotating block 1133 will rotate synchronously. When the rotating arm 1134 rotates, the slider 1136 docked at one side of the rotating arm 1134 will perform an upward movement in advance through the sliding cooperation between the moving rod 1137 and the guide rod 1138. When the slider 1136 moves to abut against the upper end sleeve of the moving rod 1137, the docking plate 1139 connected to the top of the upper end sleeve of the moving rod 1137 moves to the outer end of the guide rod 1138, thereby driving the push bar 11310 and the calibration rod 11311 to move outward. Push out, extend the two calibration rods 11311 between the lockers on both sides of the bottom of the first pipe 1 or the second pipe 2, so as to limit and lock the lockers on both sides. At this time, the lockers of the first pipe 1 and the second pipe 2 are limited, so that the first pipe 1 and the second pipe 2 cannot rotate, and the lockers between the two correspond to each other. When the positions of the lockers on the first pipe 1 and the second pipe 2 correspond to each other, insert the second pipe 2 into the integral rubber sealing ring sleeve joint 3 on the first pipe 1, and then insert the bolt pull rod 8 into the vertical plates 4 of the lockers on the first pipe 1 and the second pipe 2 accordingly, and lock them with the first nut 9 and the second nut 10 to complete the fastening and docking of the first pipe 1, the integral rubber sealing ring sleeve joint 3 and the second pipe 2;

[0061] The first supporting assembly 11 is withdrawn from the first pipe 1 and arranged at the set position of the next pipe to be docked, and the second supporting assembly 12 is moved to the second pipe 2 and the next pipe to be docked position. Then the servo motor 1132 is driven to continue to work, and the rotating arm 1134 continues to rotate, driving the slider 1136 to move up and down on the moving rod 1137, while the upper sleeve of the moving rod 1137 moves toward the inner side of the guide rod 1138, that is, moves toward the supporting seat 111, and the docking plate 1139 drives the push bar 11310 and the calibration rod 11311 to move inward for the next pipe docking work.
