Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to a hanging conversion type wire rope damping device. Background Art

[0002] The wire rope damping device belongs to the sub-field of vibration control and damping technology in the field of mechanical engineering. It utilizes the flexibility and tensile strength of the wire rope to absorb and dissipate vibration energy, thereby reducing the impact of vibration on equipment or structures. Such devices are commonly used in applications that require high reliability and durability, such as vibration damping in mechanical equipment, aerospace, ship engineering, and building structures.

[0003] The stiffness and deformation characteristics of the wire rope are determined by its material, diameter, length, and braiding method. Once these characteristics are determined, the response of the wire rope when subjected to external vibration or impact is basically fixed. Therefore, it is impossible to freely adjust the amplitude without changing the properties of the wire rope itself. However, for highly sensitive electronic devices, optical instruments, experimental equipment, and other precision equipment, excessive buffering amplitude will cause component displacement, damage, or affect the calibration accuracy of the equipment.

[0004] In view of this, we propose a hanging conversion type wire rope damping device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hanging conversion type wire rope damping device, which solves the problem that excessive buffering amplitude will cause component displacement, damage, or affect the calibration accuracy of highly sensitive electronic devices, optical instruments, experimental equipment, and other precision equipment.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A hanging conversion type wire rope damping device includes an adapter frame and a wire rope damper. The adapter frame is fixedly connected with a fixed long block, the outer wall of the fixed long block is fixed to the wire rope damper, and a limiting mechanism is arranged on the adapter frame. The limiting mechanism includes: an upper connecting rod, a lower connecting rod, a threaded rod, an adjusting bolt, and a limiting disc block. A secondary buffering mechanism is arranged on the inner wall of the lower connecting rod. The secondary buffering mechanism includes: a fixed ring. The inner wall of the lower connecting rod is fixedly connected with a fixed ring. One end of a telescopic sleeve is fixedly connected to the fixed ring, and the other end of the telescopic sleeve is fixedly connected with a resisting ring. The outer wall of the resisting ring is elastically connected to the fixed ring through a return spring. An air outlet hole is opened on the inner wall of the fixed ring, and a fixing plate is fixedly connected to the inner wall of the air outlet hole. A sealing block is elastically connected to the outer wall of the fixing plate through a holding spring, and small ventilation holes are opened on the surface of the sealing block.

[0008] Preferably, the outer wall of the adapter bracket is hinged to the upper connecting rod, the outer wall of the adapter bracket is hinged to the lower connecting rod, the inner wall of the upper connecting rod is threadedly connected to the threaded rod, the outer wall of the threaded rod is threadedly connected to the adjusting bolt, and one side of the threaded rod away from the upper connecting rod is fixed to the limiting disc block.

[0009] Preferably, one end of the return spring is fixedly connected with a contact ring, and the other end of the return spring is fixedly connected with a fixing ring.

[0010] Preferably, one end of the holding spring is fixedly connected with a fixing plate, and the other end of the holding spring is fixedly connected with a sealing block.

[0011] Preferably, the outer wall of the contact ring is slidably connected to the inner wall of the lower connecting rod, and the fixing ring and the contact ring are circular rings.

[0013] Preferably, the outer wall of the limiting disc block is slidably connected to the inner wall of the lower connecting rod, and a through groove is formed in the outer wall of the lower connecting rod.

[0014] By means of the above technical solution, the utility model provides a hanging conversion type wire rope damping device, which at least has the following beneficial effects:

[0015] (1) By arranging a secondary buffering mechanism in the utility model, when the contact ring is extruded, the contact ring extrudes the telescopic sleeve and the return spring. At this time, the return spring is compressed and stores energy, and the impact force is converted into the compression energy of the return spring, playing a role of secondary buffering. When the impact force ends, the outside air can only slowly enter through the small vent holes. Therefore, under the action of the outside atmospheric pressure, the return spring can only drive the contact ring to slowly return to its original position, avoiding causing a secondary impact on the fixed equipment, and further playing a role in protecting the highly sensitive and precision equipment during transportation.

[0016] (2) By arranging a limiting mechanism in the utility model, when it is necessary to adjust the amplitude of the wire rope damper, first rotate the threaded rod to make the threaded rod drive the limiting disc block to move to a suitable position. The distance between the limiting disc block and the following secondary buffering mechanism is the upper amplitude, and then rotate the adjusting bolt to a suitable position. The distance between the adjusting bolt and the above secondary buffering mechanism is the lower amplitude. The upper and lower amplitudes can be freely adjusted according to the characteristics of the transported items, playing a role in protecting the highly sensitive and precision equipment.

[0017] (3) The utility model is provided with a wire rope shock absorber. During the transportation of the equipment, the vibration and impact generated externally are transmitted to the wire rope shock absorber through the adapter frame and the fixed long block, causing the wire rope shock absorber to deform. During the deformation process, it can effectively absorb external energy and slowly dissipate it, playing a good protective role for the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0026] Please refer to Figures 1-5As shown, the utility model provides a technical solution: a hanging conversion type wire rope vibration reduction device, including an adapter frame 1 and a wire rope vibration reduction device 2, the adapter frame 1 is fixedly connected with a fixed long strip block 3, the outer wall of the fixed long strip block 3 is fixed to the wire rope vibration reduction device 2, during the transportation of the equipment, the vibration and impact generated by the outside world are transmitted to the wire rope vibration reduction device 2 through the adapter frame 1 and the fixed long strip block 3, so that the wire rope vibration reduction device 2 is deformed, and during the deformation process, it can effectively absorb the external energy and slowly dissipate it, which plays a good protective role for the equipment, and a limiting mechanism 4 is arranged on the adapter frame 1, and the limiting mechanism 4 includes: an upper connecting rod 41, a lower connecting rod 42, and a threaded rod 43. , adjusting bolts 44, limiting disc block 45, a secondary buffer mechanism 5 is arranged on the inner wall of the lower connecting rod 42, and the secondary buffer mechanism 5 comprises: a fixing ring 51, a fixing ring 51 is fixedly connected to the inner wall of the lower connecting rod 42, one end of the telescopic sleeve 52 is fixedly connected to the fixing ring 51, and the other end of the telescopic sleeve 52 is fixedly connected to the contact ring 53, the outer wall of the contact ring 53 is elastically connected to the fixing ring 51 through a return spring 54, an air outlet 55 is provided on the inner wall of the fixing ring 51, a fixing plate 56 is fixedly connected to the inner wall of the air outlet 55, a sealing block 58 is elastically connected to the outer wall of the fixing plate 56 through a retaining spring 57, and a small air vent 59 is provided on the surface of the sealing block 58. When the contact ring 53 is squeezed, the contact ring 53 squeezes the telescopic sleeve 52 and the return spring 54, at which time the return spring 54 is compressed and stored, and the impact force is converted into the compression storage force of the return spring 54, which plays a role of secondary buffering. When the impact force ends, the outside air can only enter slowly through the small vent hole 59. Therefore, under the action of the outside atmospheric pressure, the return spring 54 can only drive the resistance ring 53 to return slowly. Therefore, after the limiting disc block 45 returns, the resistance ring 53 returns slowly, avoiding the secondary impact of the limiting disc block 45 caused by the faster return of the resistance ring 53, thereby causing a secondary impact on the fixed equipment, further playing a role in protecting highly sensitive precision equipment during transportation.

[0027] The outer wall of the adapter frame 1 is hinged to the upper connecting rod 41, the outer wall of the adapter frame 1 is hinged to the lower connecting rod 42, the inner wall of the upper connecting rod 41 is threadedly connected to the threaded rod 43, the outer wall of the threaded rod 43 is threadedly connected to the adjusting bolt 44, and the side of the threaded rod 43 away from the upper connecting rod 41 is fixed to the limiting disc block 45. When the amplitude of the wire rope vibration damper 2 needs to be adjusted, the threaded rod 43 is first rotated so that the threaded rod 43 drives the limiting disc block 45 to move to a suitable position, and the distance between the limiting disc block 45 and the secondary buffer mechanism 5 below is the upper amplitude, and then the adjusting bolt 44 is rotated to a suitable position, and the distance between the adjusting bolt 44 and the secondary buffer mechanism 5 above is the lower amplitude. The upper and lower amplitudes can be freely adjusted according to the characteristics of the transported items, which plays a role in protecting highly sensitive precision equipment.

[0028] One end of the return spring 54 is fixedly connected with a contact ring 53, and the other end of the return spring 54 is fixedly connected with a fixed ring 51. So that the contact ring 53 and the fixed ring 51 are elastically connected. One end of the holding spring 57 is fixedly connected with a fixed plate 56, and the other end of the holding spring 57 is fixedly connected with a sealing block 58. The elastic force of the holding spring 57 makes the sealing block 58 tightly contact the inner wall of the air outlet 55. The outer wall of the contact ring 53 is slidably connected with the inner wall of the lower connecting rod 42, and the fixed ring 51 and the contact ring 53 are circular rings. It is convenient for the threaded rod 43 to pass through. The number of the limiting mechanisms 4 is two, and the two limiting mechanisms 4 are arranged symmetrically. So that the two sides of the transfer rack 1 are evenly limited in movement.

[0029] The outer wall of the limiting disc block 45 is slidably connected with the inner wall of the lower connecting rod 42. A through groove is formed in the outer wall of the lower connecting rod 42, which is convenient for observing the position of the limiting disc block 45 and more convenient for adjusting the length of the limiting disc block 45.

[0030] When the hanging conversion type wire rope shock absorber device of the present utility model is in use, the ordinary hanging installation form between the transfer rack 1 and the wire rope shock absorber 2 is converted into the tangential installation of the wire rope shock absorber 2. The original force receiving mode is changed from vertical tension to tangential compression, which improves the overall stability of the system and the fatigue life of the wire rope shock absorber 2. During the transportation of the equipment, the vibration and impact generated by the outside are transmitted to the wire rope shock absorber 2 through the transfer rack 1 and the fixed long block 3, causing the wire rope shock absorber 2 to deform. During the deformation process, the external energy can be effectively absorbed and slowly dissipated, playing a good role in protecting the equipment.

[0031] When it is necessary to adjust the amplitude of the wire rope shock absorber 2, first rotate the threaded rod 43 so that the threaded rod 43 drives the limiting disc block 45 to move to a suitable position. The distance between the limiting disc block 45 and the following secondary buffer mechanism 5 is the upper amplitude. Then rotate the adjusting bolt 44 to a suitable position. The distance between the adjusting bolt 44 and the upper secondary buffer mechanism 5 is the lower amplitude. The upper and lower amplitudes can be freely adjusted according to the characteristics of the transported items, playing a role in protecting highly sensitive precision equipment.

[0032] When the two transfer racks 1 stretch the wire rope shock absorber 2, at this time the wire rope shock absorber 2 provides the first buffer. When the two transfer racks 1 continue to stretch, they drive the upper connecting rod 41 and the lower connecting rod 42 to move away from each other. The upper connecting rod 41 drives the threaded rod 43 and the limiting disc block 45 to move towards the lower secondary buffer mechanism 5. At this time, the limiting disc block 45 squeezes the contact ring 53, and the contact ring 53 squeezes the telescopic sleeve 52 and the return spring 54. At this time, the return spring 54 is compressed and stores energy, and the impact force is converted into the compression energy storage of the return spring 54, playing a role of secondary buffer.

[0033] At the same time, the air in the telescopic sleeve 52 quickly squeezes the sealing block 58, and the sealing block 58 squeezes the retaining spring 57, so that the air in the telescopic sleeve 52 is quickly discharged. When the impact force ends, the wire rope vibration absorber 2 drives the two adapter frames 1 to return, drives the upper connecting rod 41 and the lower connecting rod 42 to return, and the upper connecting rod 41 drives the threaded rod 43 and the limiting disc block 45 to return. At this time, the limiting disc block 45 no longer squeezes the resistance ring 53, and the return spring 54 drives the resistance ring 53 to return in the direction away from the fixed ring 51. However, at this time, the air in the telescopic sleeve 52 is in a negative pressure state, and the outside air can only enter slowly through the small vent hole 59. Therefore, under the action of the outside atmospheric pressure, the return spring 54 can only drive the resistance ring 53 to return slowly. Therefore, after the limiting disc block 45 returns, the resistance ring 53 returns slowly, avoiding the secondary impact of the resistance ring 53 returning quickly on the limiting disc block 45, thereby causing a secondary impact on the fixed equipment, further playing a role in protecting highly sensitive precision equipment during transportation.

[0034] When the two adapter frames 1 are squeezed, the upper connecting rod 41 and the lower connecting rod 42 of the two adapter frames 1 move towards each other, and the upper connecting rod 41 drives the threaded rod 43 and the adjusting bolt 44 to impact the upper secondary buffer mechanism 5, which can also play a role of secondary buffering and avoiding secondary impact.
