Description

Technical Field

[0001] This utility model relates to the field of highway transportation technology, and in particular to a vibration damping device for steel wire ropes used in transportation. Background Technology

[0002] Wire rope vibration dampers are widely used vibration reduction devices in the machinery field. Their core function is to absorb and reduce mechanical vibration, protecting equipment from damage caused by vibration and impact. They also reduce noise, improve work efficiency, and extend service life. They typically consist of wire ropes, upper and lower fixing plates, fixing screws, and other components. Wire rope vibration dampers utilize the friction and slippage between strands and wires of the wire rope to achieve vibration isolation and buffering. They can withstand shear, roll, and tensile / compressive loads. They possess nonlinear stiffness and nonlinear damping characteristics, can withstand large deformations, have strong environmental adaptability, long service life, and good buffering and impact resistance. They can function effectively in harsh environments such as high and low temperatures and chemical pollution, and can work in various environments, including airborne, vehicle-mounted, and shipborne applications.

[0003] Existing wire rope vibration dampers connect equipment and foundations using pre-drilled bolt holes. They utilize the elasticity of the wire rope to reduce and eliminate vibrations transmitted from the equipment to the foundation or vice versa. Common wire rope vibration damper structures mainly include three types: spiral, arch, and drum. Spiral structures consist of multiple strands of steel wire coaxially spirally wound into a cylinder or cone, forming a layered elastic body. Its stiffness increases with the spiral angle, making it suitable for vertical steady-state load scenarios. Arch structures consist of one or more steel wire ropes bent into an arc shape, fixed at both ends to the base. The axial compression deformation of the arch generates radial stiffness, providing both vertical load-bearing capacity and limited lateral resistance to displacement. Drum structures use a three-dimensional orthogonal weaving process to interweave steel wire ropes into a dense drum-shaped mesh. Energy is dissipated through friction between the mesh nodes, making them particularly effective in multi-directional micro-amplitude vibration scenarios such as ship power foundations. Although these three structures differ in form, they all rely on a solidified, one-piece design, have unadjustable parameters, and poor combinability and scalability, making them difficult to adapt to dynamic and changing operating conditions.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] See Figures 1 to 3The structure of this utility model embodiment includes an upper clamping plate unit 1, a sliding mechanism 2, a lower clamping plate unit 3, a wire rope ring 103, and a base plate 4. The sliding mechanism 2 is provided on the top of the upper clamping plate unit 1. The upper clamping plate unit 1 includes an upper clamping plate 101 and an upper arc-shaped clamping plate 102. The upper arc-shaped clamping plate 102 is located below the upper clamping plate 101. The lower surface of the upper clamping plate 101 (the contact surface with the upper arc-shaped clamping plate 102) is arc-shaped. An upper clamping plate oblique through groove is provided on the lower surface of the upper clamping plate 101. The upper surface of the upper arc-shaped clamping plate 102 is correspondingly provided with an upper arc-shaped clamping plate oblique through groove. The lower clamping plate unit 3 includes a lower arc-shaped clamping plate 301. The base plate 4 is located below the lower arc-shaped clamping plate 301. The upper surface of the base plate 4 (the contact surface with the lower arc-shaped clamping plate 301) is arc-shaped. The base plate 4 is arc-shaped, with a base plate oblique through groove on its upper surface and a corresponding lower arc-shaped clamping plate oblique through groove on its lower surface. The upper part of the wire rope ring 103 is inserted between the upper clamping plate oblique through groove and the upper arc-shaped clamping plate oblique through groove, and the lower part of the wire rope ring 103 is inserted between the base plate oblique through groove and the lower arc-shaped clamping plate oblique through groove. The upper clamping plate 101 has upper clamping plate bolt holes, the upper arc-shaped clamping plate 102 has corresponding upper arc-shaped clamping plate bolt holes, the base plate 4 has base plate bolt holes, and the lower arc-shaped clamping plate 301 has corresponding lower arc-shaped clamping plate bolt holes. The upper clamping plate bolt holes and the upper arc-shaped clamping plate bolt holes, as well as the base plate bolt holes and the lower arc-shaped clamping plate bolt holes, are all connected by bolts 104 (internal hex bolts). There are multiple bolt holes on the upper clamping plate 101, and multiple bolt holes on the upper arc-shaped clamping plate 102. There are multiple bolt holes on the bottom plate 4, and multiple bolt holes on the lower arc-shaped clamping plate 301.

[0025] The sliding mechanism 2 includes a slide rail 201, which is set on the top of the upper clamping plate 101. The slide rail 201 is slidably connected to the upper clamping plate 101. The upper clamping plate 101 can slide left and right along the slide rail 201. The angle of the wire rope ring 103 can be adjusted by moving it. It is suitable for economical and efficient use in the field of transportation vibration reduction.

[0026] The slide rail 201 has a threaded mounting hole 202, and the upper clamping plate 101 has a corresponding threaded mounting hole 202. The threaded mounting hole 202 and the upper clamping plate threaded mounting hole are connected by adjusting bolts 203 (hex socket head cap screws). There are multiple threaded mounting holes 202, which are evenly distributed on the slide rail 201, and there are multiple threaded mounting holes on the upper clamping plate 101.

[0027] There are multiple upper clamping plate units 1 and lower clamping plate units 3, symmetrically spaced between the slide rail 201 and the base plate 4, and correspondingly multiple wire rope loops 103. The number of wire rope loops 103 can be adjusted according to the working conditions. In this embodiment, there are two upper clamping plate units 1 and two lower clamping plate units 3, and 12 wire rope loops 103.

[0028] Both ends of the slide rail 201 extend outwards from the outer side of the upper clamping plate unit 1, and both ends of the base plate 4 extend outwards from the outer side of the lower clamping plate unit 3. The extended portions of both the slide rail 201 and the base plate 4 are provided with pre-drilled bolt holes 204. When there are multiple upper clamping plate units 1 and lower clamping plate units 3, pre-drilled bolt holes 204 are also provided on the slide rail 201 between two adjacent upper clamping plate units 1 and on the base plate 4 between two adjacent lower clamping plate units 3. The slide rail 201 is connected to the equipment requiring vibration damping through the pre-drilled bolt holes 204; the base plate 4 is connected to the foundation through the pre-drilled bolt holes 204, both in a fixed position. The vertical positions of the slide rail 201 and the base plate 4 are relatively stable. The lower arc-shaped clamping plate 301 and the base plate 4 are fixed and do not require adjustment. The installation angle of the wire rope ring is adjusted by controlling the position of the upper clamping plate unit 1 within the slide rail 202, thereby adjusting the vibration damping performance of the device.

[0029] See Figure 2 When considering vibration reduction during cargo transportation, this utility model takes into account the changing weight and form of the cargo, as well as the altered vibration conditions due to road conditions. Therefore, this utility model designs a sliding mechanism 2. The upper arc-shaped clamping plate 102 can slide within the slide rail 201 of the sliding mechanism 2 according to actual needs, changing the inclination angle of the wire rope ring 103, thereby altering the vibration damping in three directions. Different fixed positions (fixed using adjusting bolts 203) correspond to different inclination angles of the wire rope ring. This can be calculated based on specific dimensions during the design phase, such as... Figure 2 As shown, this embodiment has three fixed positions: position 1, position 2, and position 3. The wire rope loops 103 on the left and right sides can be selectively fixed at one of positions 1, 2, and 3 respectively, corresponding to fixed tilt angles of 0°, 30°, and 45°, via the sliding of the upper clamping plate unit 1. The wire rope loops 103 on both sides are symmetrically arranged to ensure structural stability. The vibration reduction performance of this device also changes with the change in the tilt angle of the wire rope loops 103.

[0030] The slide rail 201 serves two purposes: first, it acts as a sliding track for the upper clamping plate 101; second, it connects the upper support plate and the upper connecting parts. In other words, during actual use, the slide rail 201 connects to the equipment requiring vibration damping via pre-drilled bolt holes 204; the base plate 4 connects to the foundation via pre-drilled bolt holes 204. The slide rail 201 and base plate 4 maintain relatively stable vertical positions. The lower arc-shaped clamping plate 301 and base plate 4 are fixed and do not require adjustment. The installation angle of the wire rope rings is adjusted by the position of the upper clamping plate unit 1 within the slide rail 202, thus adjusting the vibration damping performance of the device. The upper arc-shaped clamping plate 102 and the lower arc-shaped clamping plate 301 are supported by wire ropes. Regardless of the sliding position, the several symmetrically arranged wire rope rings 103 on the left and right sides form a vibration damping device. This symmetry maintains stability and counteracts overturning forces. From a practical application perspective, a vibration damper serves as a fulcrum for the entire vibration damping system. Therefore, the pressure on the vibration damper is evenly distributed across the entire slide rail 201 and base plate 4, and is flexibly supported by steel wire ropes. The fact that the middle part of the entire device is "suspended" does not affect the strength of the device.

[0031] The applicant conducted stiffness performance tests on a physical sample of this utility model, and the test results show that this utility model does indeed possess the corresponding performance advantages. Examples of hysteresis loops in the X, Y, and Z directions generated from the experimental data are shown below. Figure 4 As shown (a location).

[0032] This invention redesigns the upper and lower straight plates into upper and lower arc-shaped clamps without affecting the basic vibration damping principle and effect of the damper. Because the wire rope is fixed in the area between the plates, regardless of whether it passes through a straight or arc-shaped plate, the damping effect of the wire rope itself remains unchanged (due to the unchanged elastic properties of the wire rope). The purpose of using the arc-shaped clamps is to improve the service life of the wire rope, thereby increasing the lifespan of the entire vibration damping device. It is evident from existing wire rope structures that, with wire ropes fixed to straight plates, the rope abruptly changes from a straight line to an arc at the joints on both sides where the wire rope and the straight plate are fixed, resulting in a sudden change in the wire rope structure. Therefore, during use, the forces in the X, Y, and Z directions cause significant stress concentration in the wire rope loops at the point where the straight line becomes a curve. This is especially problematic under reciprocating alternating loads, significantly affecting the fatigue strength of the wire rope. However, using arc-shaped clamps allows for the design of the arc angle to ensure the wire rope loops maintain their natural curved shape, based on the size of the wire rope loops and the width of the clamps. The design of the arc-shaped clamp can minimize stress concentration during the use of the wire rope and improve its service life.

[0033] The implementation principle of the steel wire rope vibration damping device for transportation in this embodiment is as follows: The device is installed in a suitable position, and the number of steel wire rope loops 103 and the installation angle can be adjusted according to the working conditions, making the vibration damping performance adjustable and increasing the ease of manufacturing, installation, and disassembly during use. The steel wire rope vibration damping device for transportation has a large isolation range and can withstand vertical (Z-axis), lateral (X-axis), and longitudinal (Y-axis) loads. This utility model uses metallic materials, which are resistant to high temperatures and corrosion; its performance is relatively stable, its structure is simple, and its service life is long. Utilizing the elastic element characteristics of the steel wire rope, it reduces and eliminates vibrations transmitted from the equipment to the foundation or from the foundation to the equipment. By adding a slide rail 201 to the upper clamping unit 1, the installation angle of the steel wire rope loops 103 can be adjusted by moving the upper clamping unit 1. Applicable to different transportation working conditions, it offers a relatively economical and efficient use in the field of transportation vibration damping.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
