Description

Technical Field

[0001] This invention belongs to the technical field of bellows compensators, and particularly relates to an adjustable bellows compensator. Background Technology

[0002] A bellows compensator is a flexible, thin-walled device with transverse corrugations and expansion function. Its working principle mainly utilizes its own elastic expansion and contraction function to compensate for the axial, angular, lateral and combined displacements of pipelines caused by thermal deformation, mechanical deformation and various mechanical vibrations, thereby reducing pipeline deformation and improving pipeline service life. Bellows compensators are usually connected to the pipeline with bolts. When the pipeline does not have the conditions for bolt connection, it cannot be used, which limits its application environment. This paper proposes an adjustable bellows compensator that is suitable for various connection environments, does not require bolt connection, and can automatically adjust the clamping force of the connector.

[0018] Beneficial effects

[0019] This invention provides a bellows-adjustable compensator, which has the following advantages compared with the prior art:

[0020] 1. After the two pipe sections are connected using this device, when an external force is applied to the pipe and the bellows is stretched, the third lead screw moves downward in the bushing and disengages from the shaft, causing the shaft to drive the fifth gear to rotate. This causes the first worm gear to drive the first connecting rod to rotate synchronously. The first connecting rod drives the second connecting rods and the fourth connecting rod on both sides to rotate synchronously. The rotation of the fourth connecting rod causes the first clamping plate, which is threaded to the first lead screw, to move vertically upward. The rotation of the fourth connecting rod drives the third connecting rod to rotate synchronously. The fifth connecting rod drives the second clamping plate, which is threaded to the second lead screw, to move vertically upward. The first clamping plate and the second clamping plate move closer to each other, clamping the pipe between the first clamping plate and the second clamping plate. As the external force increases, the clamping force also increases, thereby preventing the external force from interrupting the connection of the pipe.

[0021] 2. Under the action of external force, the third lead screw slides downward, causing the third lead screw to rotate horizontally, so that the first angle steel drives the hammer to make a circular motion around the shaft plate as the fulcrum, striking the bellows, thereby removing the rust on the bellows and the deposits brought by the pipe inside the bellows through vibration.

[0036] The second connecting rod 103 includes a second worm gear 1031 and a third gear 1032. The second worm gear 1031 is fixedly connected to the second connecting rod 103 on one side and meshes with the first gear 1022. The third gear 1032 is fixedly connected to the second connecting rod 103 on the other side and meshes with the third worm gear 1041.

[0037] The fourth connecting rod 105 includes a first lead screw 1051 and a fifth worm gear 1052. The first lead screw 1051 is fixedly connected to the fourth connecting rod 105. The first lead screw 1051 is threadedly connected to the first clamping plate 107 and slidably connected to the second clamping plate 108. The fifth worm gear 1052 is fixedly connected to the fourth connecting rod 105 and meshes with the second gear 1023.

[0038] The fifth connecting rod 106 includes a fourth worm gear 1061 and a second lead screw 1062.

[0041] In this embodiment of the invention, after the two pipe sections are connected using this device, when an external force is applied to the pipes, causing the bellows 205 to be stretched, the third lead screw 201 moves downward within the bushing 202, disengaging from the shaft 204. This causes the shaft 204 to drive the fifth gear 203 to rotate, causing the first worm gear 1021 to drive the first connecting rod 102 to rotate synchronously. The first connecting rod 102 then drives the second connecting rods 103 and the fourth connecting rod 105 on both sides to rotate synchronously. The rotation of the fourth connecting rod 105 causes the threaded connection with the first lead screw 1051 to... The first clamping plate 107 moves vertically upwards.

The fifth connecting rod 106 drives the second clamping plate 108, which is threadedly connected to the second lead screw 1062, to move vertically upwards. The first clamping plate 107 and the second clamping plate 108 move closer to each other, clamping the pipe between the first clamping plate 107 and the second clamping plate 108. As the external force increases, the clamping force also increases, thereby preventing the external force from causing the connection of the pipe to be interrupted.

[0043] Preferably, a spring is fixedly connected to one side of the hammer 304, and a washer is fixedly connected to the other side of the spring. The purpose of this arrangement is to increase the buffer and prevent the impact of the first angle steel 302 from damaging the bellows 205.

[0044] In this embodiment of the invention, under the action of external force, the third lead screw 201 slides downward, causing the third lead screw 201 to rotate horizontally, so that the first angle steel 302 drives the hammer 304 to make a circular motion with the shaft disk 301 as the fulcrum, and strikes the bellows 205, thereby removing the rust on the bellows 205 and the deposits brought by the pipe inside the bellows 205 through vibration.
