Description

Technical Field

[0001] The utility model relates to the technical field of hangers, in particular to a hanger with a compensating anti-torque disc spring. Background Art

[0002] Disc spring supports are mainly used in suspension devices with thermal displacement such as power, petroleum, and chemical pipeline systems or boiler equipment. When the pipeline or equipment is displaced, as long as it is within the pre-selected load displacement, no matter how large the displacement change is, they can always obtain a constant supporting force through the constant force spring bracket.

[0003] A Chinese patent with publication number CN219413961U discloses a disc spring hanger with compensating torque resistance, which has the advantages of a larger range of motion, which means that the disc spring hanger has a stronger ability to compensate for torque resistance, while reducing the stress on the pipeline and reducing pipeline wear.

[0004] The installation and disassembly steps between the outer sleeve and the fixed sleeve in the above patent document are relatively complicated. When the mechanical structure located in the outer sleeve needs to be repaired or replaced, it takes a long time to disassemble the outer sleeve and the fixed sleeve. At the same time, the narrow space in the outer sleeve is not convenient for maintenance operations. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] Reference Figure 1-Figure 4 As shown, a disc spring support hanger with compensating torque resistance comprises two semi-annular outer sleeves 1 and a fixed sleeve 2, the two outer sleeves 1 are rotatably connected by a rotating shaft 3, a socket 4 is vertically opened on the upper surface of the outer sleeve 1, a plug plate 5 is symmetrically fixedly installed on the lower surface of the fixed sleeve 2, a pressure block 6 is fixedly installed on the bottom end of the plug plate 5, mounting grooves are horizontally opened on the left and right walls of the socket 4, a spring rod 7 is horizontally fixedly installed in the mounting groove, a triangular locking block 8 is fixedly installed on one end of the spring rod 7 located in the socket 4; locking openings 9 for inserting the locking block 8 are symmetrically opened on the surface of the plug plate 5, the shape of the pressure block 6 is an isosceles trapezoid, the surface of the outer sleeve 1 is symmetrically opened with through openings respectively connected with the two mounting grooves, and a pull rod 10 is fixedly installed on the surface at one end of the spring rod 7.

[0019] When it is necessary to complete the installation between the two outer sleeves 1 and the fixed sleeve 2, first control the two outer sleeves 1 to approach each other until they are against each other and closed. At this time, the two plug plates 5 on the lower surface of the fixed sleeve 2 are respectively aligned with the two sockets 4 and inserted. The two inclined surfaces of the pressing block 6 will respectively slide in contact with the inclined surfaces of the two locking blocks 8. Under the action of the inclined surface pressure, the two spring rods 7 will shrink together until the bottom end of the pressing block 6 is against the bottom wall of the socket 4. At this time, the two locking blocks 8 will respectively correspond to the positions of the two locking ports 9. The pressing force applied to the locking blocks 8 disappears, and the two locking blocks 8 will quickly move and reset under the elastic potential energy of the spring rods 7. The two locking blocks 8 will be respectively inserted into the two locking ports 9, thereby completing the locking of the two outer sleeves 1 and the fixed sleeve 2.

[0020] When disassembly is required, it is only necessary to control the movement of the multiple pull rods 10 to shrink the multiple spring rods 7 until the multiple locking blocks 8 are respectively moved out of the multiple locking openings 9, so as to complete the release of the locks of the two outer sleeves 1 and the fixed sleeve 2, and then move the fixed sleeve 2 upward to move the two plug plates 5 out of the two sockets 4 respectively. At this time, the two outer sleeves 1 are rotated to expose the mechanical parts inside them to the outside, which is convenient for maintenance operations.

[0021] The outer sleeve 1 is provided with a pressing assembly on its surface, and the pressing assembly is used to control the two spring rods 7 to contract together. The pressing assembly includes an arc rod 11, two L-shaped pressing rods 12 fixedly mounted on the upper surface of the arc rod 11, and two inclined plates 13. The two inclined plates 13 are respectively fixedly mounted on one end of the two pull rods 10, and the two pressing rods 12 are respectively located below the two inclined plates 13. A mounting plate 14 is fixedly mounted on the surface of the outer sleeve 1, and a through hole is opened on the surface of the mounting plate 14. A mounting rod 15 is fixedly mounted on the lower surface of the arc rod 11. The mounting rod 1 The two spring rods 7 are slidably inserted in the through opening and connected to the mounting plate 14 through a telescopic component, which includes a telescopic spring 16 sleeved on the mounting rod 15. A mounting block is fixedly mounted on the bottom end of the mounting rod 15. The two ends of the telescopic spring 16 are respectively fixedly connected to the mounting block and the mounting plate 14. By controlling the arc rod 11 to move upward, the surfaces of the two pressing rods 12 will respectively slide in contact with the inclined surfaces of the two inclined plates 13. Under the action of the inclined surfaces, the two spring rods 7 will shrink together, and there is no need to control the shrinkage of the two spring rods 7 one by one.

[0022] An extension block 17 is fixedly installed at the end of one of the arc rods 11, and an entrance 18 for the extension block 17 to enter is opened on the surface of the other arc rod 11; when the two outer sleeves 1 are against each other, the extension block 17 will enter the entrance 18. When it is necessary to control the multiple spring rods 7 to shrink together, it is only necessary to control the arc rod 11 with the entrance 18 to move up. At this time, the other arc rod 11 will also move up together, and then the multiple pressure rods 12 will move up together, so that the multiple spring rods 7 can be controlled to shrink together.

[0023] The lower surfaces of the two arc-shaped rods 11 are both bonded with an anti-skid layer made of rubber. The rubber anti-skid layer has good elasticity and viscosity, thereby increasing the friction between the palm and the contact surface of the arc-shaped rod 11.

[0024] When it is necessary to complete the installation between the two outer sleeves 1 and the fixed sleeve 2, first control the two outer sleeves 1 to approach each other until they are against each other and closed. At this time, the two plug plates 5 on the lower surface of the fixed sleeve 2 are respectively aligned with the two sockets 4 and inserted. The two inclined surfaces of the pressing block 6 will slide in contact with the inclined surfaces of the two locking blocks 8 respectively. Under the action of the inclined surface pressure, the two spring rods 7 will shrink together until the bottom end of the pressing block 6 is against the bottom wall of the socket 4. At this time, the two locking blocks 8 will correspond to the positions of the two locking ports 9 respectively. The pressing force applied to the locking blocks 8 disappears, and the two locking blocks 8 will move rapidly under the elastic potential energy of the spring rods 7. After resetting, the two locking blocks 8 will be respectively inserted into the two locking openings 9, thereby completing the locking of the two outer sleeves 1 and the fixed sleeve 2. When disassembly is required, it is only necessary to control the movement of the multiple pull rods 10 to shrink the multiple spring rods 7 until the multiple locking blocks 8 are respectively moved out of the multiple locking openings 9, so that the two outer sleeves 1 and the fixed sleeve 2 can be unlocked. The disassembly and assembly of the two outer sleeves 1 and the fixed sleeve 2 can be quickly completed, and then the fixed sleeve 2 can be moved up to move the two plug plates 5 out of the two sockets 4 respectively. At this time, the two outer sleeves 1 are rotated to expose the mechanical parts inside them to the outside, which is convenient for maintenance operations.
