Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe joint, in particular to a universal hinge combined corrugated compensator. BACKGROUND

[0002] The universal hinge type corrugated compensator is a perturbation element with a corrugated pipe as the core, which can compensate in multiple directions on the pipeline. The universal hinge compensator, which is used in pairs or three, can absorb the deformation in three-dimensional directions. The metal corrugated pipe cannot be bent arbitrarily like the rubber corrugated pipe. If the metal corrugated pipe is bent and deformed frequently in a short period of time, it may be damaged by excessive bending, thereby causing leakage of the pipeline conveying medium. The universal hinge combined corrugated compensator is connected between two pipelines to release pressure by relative displacement between the two pipelines. The deformation of the compensator ensures stable connection between the two pipelines. In order to prevent damage to the metal corrugated pipe and irreversible repair of the corrugated pipe, a buffer suppression mechanism is needed when the two pipelines move excessively relative to each other to avoid frequent excessive bending of the metal corrugated pipe. Therefore, the present application provides a universal hinge combined corrugated compensator. SUMMARY

[0042] The pressing group 38 comprises a spring 47 fixedly sleeved outside the double control shaft 42, a pushing tool 49 fixedly sleeved outside the spring 47, a disc tool 48 clamped at one side of the pushing tool 49, a double position frame 46 for limiting the disc tool 48 and the pushing tool 49 at the same time, a backstop spring 50 for controlling the disc tool 48 abutting against the pushing tool 49, and a concave spring 45 connected between the disc tool 48 and the double plate 35, one end of the double position frame 46 is fixed on the second plate frame 36, both ends of the concave spring 45 are S-shaped plates, the double position frame 46 is clamped into a ring groove formed on the outer side wall of the pushing tool 49 by setting a ring body, the disc tool 48 slides through a ring cylinder hole formed in the ring cylinder of the double position frame 46, one end of the backstop spring 50 is fixed on the ring cylinder of the double position frame 46, and the other end of the backstop spring 50 is placed on the bottom surface of the disc tool 48.

[0043] The pushing tool 49 comprises a disc body, a cylinder body fixed at one side of the disc body, and a V-shaped cross column fixed at the middle of the other side of the disc body, the disc tool 48 comprises a disc body and two symmetrical arc plates fixed at one side of the disc body, and a V-shaped groove for clamping the V-shaped cross column of the pushing tool 49 is formed on the disc body of the disc tool 48, and the arc plates of the disc tool 48 vertically pass through arc plate sliding holes formed in the middle plate of the double plate 35.

[0044] When the universal ring cylinder 4 swings relative to the L-shaped derrick 3, the wave spring 13 pulls back the control door frame 12, so that the door frame 12 always has one end in contact with the bottom surface of the universal ring cylinder 4, and in addition, the blocking block 15 and the door frame 12 are not in contact. Specifically, the universal ring cylinder 4 drives the swing piece 6 to swing, and then drives the wave disc 20 through the limiting shaft 21, the wave disc 20 rotates and continuously drives the L-shaped cone plate 23, and then the L-shaped rack 24 reciprocates to drive the outer gear ring 51, which is converted by the one-way bearing 52 to make the one-way shaft 53 rotate intermittently and directionally, and then the temporary gear 34 rotates in place, the corrugated pipe 1 bends normally, the one-way shaft 53 does not move far enough, the L-shaped cone plate 23 drives the piston column 28 to move at a low frequency, the piston column 28 moves to cause the airflow in the square cylinder pipe 27 to flow directionally, the gas pressure in the square cylinder pipe 27 acts on the movable plate 32, the movable plate 32 extends out of the square cylinder pipe 27 for a short distance, and then the controlled fixed shaft 33 drives the temporary gear 34 to move a short distance, the temporary gear 34 is not in contact with the head gear 39, and the subsequent suppression mechanism is not triggered, so that the corrugated pipe 1 will not trigger the suppression when it is normally bent.

[0045] If the corrugated pipe 1 is excessively bent in a short period of time, the piston column 28 will stretch and contract at a high frequency, so that the airflow in the square cylinder pipe 27 moves to the movable plate 32 at a high speed, the air flowing back through the middle thin part of the V-shaped valve spring 30 is less, so that the high gas pressure acts on the movable plate 32, the movable plate 32 extends out of the square cylinder pipe 27 for a long distance, and the temporary gear 34 moves axially and comes into contact with the head gear 39, the subsequent suppression mechanism is established, and the blocking integrated 5 plays a suppression role to suppress the excessive swing of the universal ring cylinder 4. Specifically, the temporary gear 34 drives the head gear 39, and then the head shaft 40 drives the side position worm 43, and then the booster gear 44 drives the double-control shaft 42 to rotate, causing the clockwork 47 to contract and store energy. If the clockwork 47 has enough energy, it will cause the pusher 49 to rotate, breaking the clamping state between the pusher 49 and the disc 48. During the rotation of the pusher 49, the pusher 49 supports the disc 48, the disc 48 drives the concave spring 45, and then the control plate 35 moves and presses the door frame 12, the blocking block 15 is inserted into the door frame 12, and the suppression function of the blocking integrated 5 is played. Referring to Figure 4 The blocking block 15 and the door frame 12 are clamped, and the swing of the universal ring cylinder 4 will cause the door frame 12 to move to the right, the door frame 12 drives the blocking block 15, the blocking block 15 moves to the right and drives the directional T plate 16, and the movement of the directional T plate 16 will be buffered and blocked by the strong suppression spring 18, so that the swing of the universal ring cylinder 4 is buffered and suppressed.

[0046] The V-shaped column of the pusher 49 and the bottom surface of the disc 48 can be sanded, so that the relative rotation between the pusher 49 and the disc 48 is slow, and after the disc 48 and the pusher 49 are clamped and released, the time for the next re-clamping process is the time for the suppression mechanism to play a role.

[0047] Reference Figure 14 It is understood that if the universal ring cylinder 4 swings and tilts, the corresponding door-shaped frame 12 is pushed and moves to the left to the head, at this time the blocking block 15 is inserted into the door-shaped frame 12, and the inhibition mechanism will fail, only when the blocking block 15 is inserted at the leftmost end of the upper row of teeth of the door-shaped frame 12, that is, in the state shown, in addition, the universal ring cylinder 4 swings and tilts, and the door-shaped frame 12 has one end pushed and moved to the left, which will cause the blocking block 15 to move to the left, so that the inhibition mechanism works, Figure 14 The one-way inclined surface design of the door-shaped frame 12 square tooth groove in the door-shaped frame 12 can ensure that the door-shaped frame 12 moves to the right to reset, and the blocking block 15 does not move, so that the blocking block 15 and the door-shaped frame 12 are misaligned and slide, the design of the concave spring piece 45 is used to provide space for the rebound of the blocking block 15, the door-shaped frame 12 resets, and the blocking block 15 is inserted into the door-shaped frame 12 again, then the subsequent universal ring cylinder 4 swings and tilts, and the door-shaped frame 12 will buffer and inhibit the swing and tilt of the universal ring cylinder 4.
