Description

Technical Field

[0001] This utility model relates to the technical field of wire rope vibration dampers, specifically to a laterally stable dustproof wire rope vibration damper. Background Technology

[0002] Based on its unique helical winding structure, the wire rope vibration damper undergoes complex nonlinear deformation under load. Its core working mechanism utilizes the hysteretic damping effect generated by the mutual compression and frictional slippage between multiple internal steel wires to efficiently convert impact and vibration kinetic energy into heat energy dissipation. Simultaneously, the rope's own elastic deformation enables instantaneous energy storage and subsequent slow release. This synergistic mechanism of "elastic energy storage" and "frictional energy dissipation" gives it excellent nonlinear stiffness characteristics, superior broadband vibration isolation and impact resistance, extremely high load-bearing capacity, and outstanding environmental tolerance. Therefore, it has been successfully applied in numerous critical fields with extremely stringent vibration reduction and impact resistance requirements, including extreme impact resistance for military and aerospace equipment, bump protection for heavy engineering machinery and vehicles, micro-vibration isolation for high-precision industrial equipment and instruments, dynamic load buffering for large lifting and transportation machinery, suppression of generator set vibration, and protection of critical rail transit equipment. It has become a core technology and key protective component for solving the challenges of vibration and impact isolation under complex and harsh working conditions.

[0003] Existing wire rope vibration dampers have several drawbacks when used in special environments. First, lubricating oil is applied between the wire ropes during operation to extend maintenance cycles, maintain damping performance, and reduce friction and wear. However, in industrial environments, a large amount of dust inevitably settles between the wire ropes, and the lubricating oil also absorbs a significant amount of dust, thus affecting the maintenance cycle and service life of the wire rope vibration damper. Second, wire rope vibration dampers have poor lateral stability. When subjected to loads, the lateral stability of the wire rope structure is inferior to its longitudinal performance. Under large lateral forces, lateral buckling or instability is prone to occur. Furthermore, their operation is limited in some special working environments. Utility Model Content

[0004] In view of the problems of poor lateral stability and dust accumulation between wire ropes in existing wire rope vibration dampers, this utility model provides a laterally stable dustproof wire rope vibration damper.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A laterally stable dustproof wire rope vibration damper includes an upper plate, a lower plate, and a spiral wire rope connected between the upper plate and the lower plate. It also includes a dust cover and a limiting component. The dust cover is fitted over the spiral wire rope. The limiting component is disposed between the upper plate and the lower plate. The limiting assembly includes a limiting rod, a sliding ring, a transverse side plate, a longitudinal side plate, spring one, and spring two; The two transverse side plates on both sides of the length direction and the two longitudinal side plates on both sides of the width direction are fixedly connected to the lower plate respectively; The two longitudinal side plates are fixedly connected to one end of each of the two springs on their opposite sides; the other end of the spring is fixedly connected to the outer wall of the sliding ring. The two horizontal side plates are fixedly connected to one end of each of the two springs on their opposite sides; the other end of each of the two springs is fixedly connected to the radial outer wall of the sliding ring. The sliding ring is circular, with one end slidably connected to the upper surface of the lower plate; One end of the limiting rod is fixedly connected to the lower surface of the upper plate, and the other end extends into the sliding ring, and the diameter of the limiting rod is smaller than the inner diameter of the sliding ring.

[0006] Preferably, threaded holes are provided at both ends along the length of the upper plate and threaded holes are provided at both ends along the length of the lower plate.

[0011] This utility model has the following beneficial effects and advantages: 1. The laterally stable dustproof wire rope vibration damper provided by this utility model can prevent lateral bending or tilting instability when the upper or lower plate of the wire rope vibration damper is laterally displaced and exceeds the bearing capacity of the wire rope vibration damper by limiting the internal limiting components of the wire rope vibration damper, thereby further ensuring the stability of the system operation. 2.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] A laterally stable dustproof wire rope vibration damper includes an upper plate 1, a lower plate 2, and a spiral wire rope 3 connected between the upper plate 1 and the lower plate 2. It also includes a dust cover 4 and a limiting component. The dust cover 4 is sleeved on the outside of the spiral wire rope 3. The limiting component is disposed between the upper plate 1 and the lower plate 2.

[0016] The upper plate 1 and lower plate 2 of the wire rope vibration damper are fixed between the damped equipment and the fixed support, respectively; the dust cover 4 is fitted on the outside of the wire rope vibration damper, mainly for dust prevention.

[0017] The limiting assembly includes a limiting rod 501, a sliding ring 502, a transverse side plate 503, a longitudinal side plate 504, a spring 1 505, and a spring 2 506. The two transverse side plates 503 on both sides of the length direction and the two longitudinal side plates 504 on both sides of the width direction are fixedly connected to the lower plate 2 respectively; The two longitudinal side plates 504 are fixedly connected to one end of two springs 506 on opposite sides; the other end of springs 506 is fixedly connected to the outer wall of sliding ring 502. The two side plates 503 are fixedly connected to one end of two springs 505 on opposite sides; the other end of the two springs 505 is fixedly connected to the radial outer wall of the sliding ring 502. The sliding ring 502 is an annular ring, and one end of it is slidably connected to the upper surface of the lower plate 2. One end of the limiting rod 501 is fixedly connected to the lower surface of the upper plate 1, and the other end extends into the sliding ring 502; When the equipment experiences lateral vibration, it causes lateral displacement of the upper plate 1 or lower plate 2 of the wire rope vibration damper. If the lateral displacement is within the bearing capacity of the wire rope vibration damper, the limiting rod 501 moves within the sliding ring 502, and the limiting component does not work. If the lateral displacement is large and exceeds the bearing capacity of the wire rope vibration damper, the limiting rod 501 moves laterally until it abuts against the inner wall of the sliding ring 502, causing the sliding ring 502 to undergo lateral displacement, thereby compressing the first spring 505 or the second spring 506. The first spring 505 and the second spring 506 can provide lateral support for the limiting rod 501, preventing the wire rope vibration damper from buckling or becoming unstable, buffering vibration, and ensuring stable system operation.

[0018] The upper plate 1 has threaded holes 101 at both ends along its length, and the lower plate 2 has threaded holes 201 at both ends along its length.

[0019] Upper plate slots 102 are provided on both sides of the upper plate 1 along its width direction; lower plate slots 202 are provided on both sides of the lower plate 2 along its width direction.

[0020] Both the upper plate slot 102 and the lower plate slot 202 are either dovetail-shaped or trapezoidal.

[0021] The dust cover 4 has a cylindrical structure and is made of elastic fabric. Its circumferential sidewalls have a hollow structure. The edges of the hollow structure are provided with insertion strips 404, which match the upper plate slot 102 and the lower plate slot 202.

[0022] The dust cover 4 has an opening at one end, and the edge of the opening is symmetrically provided with a semi-circular cover plate A 402 and a semi-circular cover plate B 403 that can be opened and closed. The joint between the semi-circular cover plate A 402 and the semi-circular cover plate B 403 is provided with Velcro 401.

[0023] The dust cover 4 is fitted outside the wire rope vibration damper and slides into the upper plate slot 102 and the lower plate slot 202 through the plug strip 404 to achieve a fixed connection between the dust cover 4 and the wire rope vibration damper; it is fixed by the Velcro 401 on the A semi-circular cover plate 402 and the B semi-circular cover plate 403 to achieve a dustproof structure.

[0024] Working principle: First, fix the upper plate 1 and lower plate 2 of the wire rope vibration damper between the damped equipment and the fixed support, respectively, to ensure that the sliding ring 502 is sleeved outside the limit rod 501; When the equipment experiences lateral vibration, it causes lateral displacement of the upper plate 1 or lower plate 2 of the wire rope vibration damper. If the lateral displacement is within the bearing capacity of the wire rope vibration damper, the limiting rod 501 moves within the sliding ring 502, and the limiting component does not work. If the lateral displacement is large and exceeds the bearing capacity of the wire rope vibration damper, the limiting rod 501 moves laterally until it abuts against the inner wall of the sliding ring 502, causing the sliding ring 502 to undergo lateral displacement, thereby compressing the first spring 505 or the second spring 506. The presence of the first spring 505 and the second spring 506 can prevent the wire rope vibration damper from buckling laterally or becoming unstable, ensuring the stable operation of the system.

[0025] To install and replace the dust cover 4, first open the A semi-circular cover plate 402 and the B semi-circular cover plate 403, and then put the dust cover 4 onto the wire rope vibration damper. Slide the connector 404 of the dust cover 4 into the upper plate slot 102 and the lower plate slot 202 to achieve a fixed connection between the dust cover 4 and the wire rope vibration damper. Finally, use Velcro 401 to fix the open end of the dust cover 4 to achieve dust protection for the wire rope vibration damper.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
