Description

Technical Field

[0001] This utility model relates to the field of vibration isolator technology, specifically a clamp-type wire rope vibration isolator. Background Technology

[0002] Currently, the conventional method for using wire rope vibration isolators is to install and use a single wire rope isolator individually. However, in certain specific applications, it is necessary to reduce the stiffness and natural frequency of the isolator. Therefore, the width and height of the isolator must be increased during the design and selection process, and thicker wire ropes must be used. Consequently, wire rope vibration isolators are relatively large and require significant equipment space. This necessitates a larger system space, making it unsuitable for instruments and equipment with narrow installation spaces. This limits the application range of wire rope vibration isolators. To overcome the limitations of existing technologies, two wire rope vibration isolators are often connected in series, one above the other, to reduce the space occupied and meet the needs of installation in narrow spaces of instruments and equipment. Secondly, the increased height and vertical allowable deformation after series connection, along with the reduced stiffness, improve vibration isolation and impact resistance. However, most existing wire rope vibration isolators are fixed together with bolts during series connection, which makes the installation process cumbersome and inconvenient to use. Therefore, a clamp-type series wire rope vibration isolator is proposed. Utility Model Content

It solves the problem that existing steel wire rope vibration isolators, when connected in series, mostly rely on bolts to fix two steel wire rope vibration isolators together, resulting in a cumbersome installation process and thus being inconvenient to use.

[0005] (II) Technical Solution

[0006] To achieve the aforementioned ease of installation, this utility model provides the following technical solution: a clamp-plate series steel wire rope vibration isolator, comprising two clamp plates symmetrically distributed vertically. Each clamp plate has eight mounting holes on its front side. An annular steel wire rope, with one end fixedly connected to the inside of each of the top eight mounting holes, is disposed inside each of the bottom eight mounting holes.

[0014] This clamp-type tandem wire rope vibration isolator is installed by stacking two wire rope vibration isolators together. Then, turning the two first knobs on the bottom isolator rotates the two first threaded rods, causing the two bottom sliders and two bottom connecting blocks to move upwards. This allows the two bottom connecting blocks to insert into the two top connecting slots until the bottom sliders reach their limit positions. At this point, the two bottom positioning slots are positioned opposite the two top positioning blocks. Next, turning the two second knobs on the top rotates the two top worm gears, which in turn rotate the two top second threaded rods. This causes the two top positioning blocks to move relative to each other, with one end of each block moving into the two bottom positioning slots. This completes the tandem fixing of the two wire rope vibration isolators, achieving easy installation without the need for external tools, thus facilitating user operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a clamped plate series steel wire rope vibration isolator, including two clamped plates 1 distributed symmetrically in the upper and lower parts. Each clamped plate 1 has eight mounting holes 2 on its front side. An annular steel wire rope 3 is fixedly installed inside each of the eight mounting holes 2 at the top, with one end of each rope fixedly connected to the inside of the eight mounting holes 2 at the bottom. Since steel wire rope vibration isolators are existing technology in this field, and this utility model is mainly used to protect mechanical structures, the principle of the steel wire rope vibration isolator will not be described in detail in this application.

[0023] The top clamping plate 1 has a housing 4 fixedly installed on the left and right sides of its bottom. The top of the two housings 4 is open. The bottom of the two housings 4 has a slider 5 movably installed inside. The top clamping plate 1 has through holes 6 located above the two sliders 5 on the left and right sides of its bottom. The top of the two sliders 5 has a connecting block 7 with one end extending into the two through holes 6 respectively. The bottom of the two housings 4 is threaded with a first threaded rod 8 with one end extending into it and movably connected to the bottom of the two sliders 5 respectively. The bottom of the two housings 4 has threaded holes that are adapted to the two first threaded rods 8 respectively. The bottom of the two sliders 5 has a first bearing fixedly installed. The first threaded rod 8 is rotatably connected to the bottom of the slider 5 through the first bearing. The bottom of the two first threaded rods 8 has a first knob 9 fixedly installed.

[0024] The bottom clamping plate 1 has connecting grooves 10 on both the left and right sides of its bottom, located directly below the two connecting blocks 7. The inner walls of the opposite sides of the two connecting grooves 10 are connected to rectangular grooves 11 on the bottom clamping plate 1. The inner walls of the opposite sides of the two rectangular grooves 11 are movably installed with second threaded rods 12. The interior of the two rectangular grooves 11 is movably installed with a positioning block 13, one end of which is threaded to the outer side of the two second threaded rods 12. The inner walls of the opposite sides of the two rectangular grooves 11 are fixedly installed with second bearings. The second threaded rods 12 are rotatably connected to the inner walls of the rectangular grooves 11 through the second bearings. The opposite sides of the two positioning blocks 13 are provided with threaded grooves that are adapted to the two second threaded rods 12. The inner top walls of the two rectangular grooves 11 are connected to limiting grooves on the bottom clamping plate 1. The tops of the two positioning blocks 13 are fixedly installed with limiting blocks, one end of which extends into the two limiting grooves. The opposite sides of the two connecting blocks 7 are provided with positioning grooves 14.

[0025] Each of the two second threaded rods 12 has a rotating assembly 15 fixedly installed on its outer side, with one end movably connected to the inner bottom wall of each of the two rectangular grooves 11 and the other end extending to the top of the bottom clamping plate 1. The rotating assembly 15 includes a worm gear 151. Each of the two second threaded rods 12 has a worm gear 151 fixedly installed on its outer side, located on opposite sides of the two positioning blocks 13. Each of the two rectangular grooves 11 has a worm 152 movably installed on its inner bottom wall, with one end meshing with each of the two worm gears 151 and the other end extending to the top of the bottom clamping plate 1. Each of the two rectangular grooves 11 has a third bearing fixedly installed on its inner bottom wall, located on opposite sides of the two positioning blocks 13. The worm 152 is rotatably connected to the inner bottom wall of the rectangular groove 11 through the third bearing. Each of the two worm 152 has a second knob 153 fixedly installed on its top.

[0026] Working principle: When two wire rope vibration isolators need to be connected in series, the two wire rope vibration isolators can be stacked one on top of the other. Then, the two first knobs 9 on the bottom vibration isolator can be turned to rotate the two first threaded rods 8 at the bottom. This will cause the two bottom sliders 5 and the two bottom connecting blocks 7 to move upward, so that the two bottom connecting blocks 7 are inserted into the two top connecting slots 10 respectively, until the two bottom sliders 5 move to their limit positions. At this time, the two bottom positioning slots 14 are exactly on the opposite sides of the two top positioning blocks 13. Then, the two top... The second knob 153 drives the two top worm gears 152 to rotate, which in turn drives the two top second threaded rods 12 to rotate via the two top worm wheels 151. This causes the two top positioning blocks 13 to move relative to each other, so that one end of each of the two top positioning blocks 13 moves into the two bottom positioning slots 14. This completes the series fixing of the upper and lower wire rope vibration isolators without the need for external tools, making it convenient for users. Similarly, multiple wire rope vibration isolators can be connected in series according to actual conditions, thereby improving the applicability of the vibration isolators.

[0027] In summary, this clamp-type tandem wire rope vibration isolator works by stacking two wire rope vibration isolators that need to be connected in series one on top of the other. Then, turning the two first knobs 9 on the bottom isolator rotates the two first threaded rods 8 at the bottom, causing the two bottom sliders 5 and the two bottom connecting blocks 7 to move upwards. This allows the two bottom connecting blocks 7 to insert into the two top connecting slots 10 until the two bottom sliders 5 reach their limit positions. At this point, the two bottom positioning slots 14 are positioned opposite the two top positioning blocks 13. Then, turning the two second knobs 153 at the top rotates the two top worm gears 152. The rotation of the top two worm gears 151 drives the top two second threaded rods 12 to rotate, thereby causing the top two positioning blocks 13 to move relative to each other. This allows one end of the top two positioning blocks 13 to move into the bottom two positioning slots 14, thus completing the series connection and fixing of the upper and lower wire rope vibration isolators. This achieves the goal of easy installation without the need for external tools, making it more convenient for users. It also solves the problem that existing wire rope vibration isolators, when connected in series, mostly rely on bolts to fix the two wire rope vibration isolators together, resulting in a cumbersome installation process and hindering their use.
