Detailed Implementation
[0026] The present invention will be further described below: a skid-mounted natural gas refueling equipment anti-movement and anti-vibration device, see [link to relevant documentation]. Figures 1 to 6The system includes a natural gas refueling device 3, an anti-movement device 1, and an anti-vibration device 2. The anti-movement device 1 is located at the four corners of the natural gas refueling device 3 and confines the natural gas refueling device 3 to the foundation within the four anti-movement devices 1. The anti-vibration device 2 consists of a base 21, a limiting sleeve 22, a telescopic sleeve 23, and a shock-absorbing spring 24. The limiting sleeve 22 is fitted over the telescopic sleeve 23 and is fixedly connected to the base 21. The shock-absorbing spring 24 is located at the bottom of the telescopic sleeve 23. The telescopic sleeve 23 moves up and down along the limiting sleeve 22 through the shock-absorbing spring 24, and the limiting sleeve 22 restricts the telescopic sleeve 23 from moving up and down within a specified space. There are multiple anti-vibration devices 2, and the multiple anti-vibration devices 2 are evenly arranged at the bottom of the natural gas refueling device 3. This utility model uses the anti-movement device 1 to limit the installation of the natural gas refueling equipment 3 at its four corners, preventing the natural gas refueling equipment 3 from shifting horizontally in all directions due to vibration during operation. An anti-vibration device 2 is arranged at the bottom of the natural gas refueling equipment 3 to buffer and reduce the vertical force generated by vibration during operation, ensuring the safe and reliable operation of the natural gas refueling equipment 3.
[0027] For the design of vibration damping devices, see [reference needed]. Figures 1 to 2 The base 21 has a groove that matches the limiting sleeve 22. The inner wall of the groove has an internal thread and a hollow ring groove. The outer wall of the limiting sleeve 22 has an external thread that matches the internal thread. The limiting sleeve 22 is fixed in the groove of the base 21 by the internal and external threads. The groove design provides positioning support for the limiting sleeve 22 during installation. It has high structural strength, and the threaded connection facilitates the installation and removal of the limiting sleeve 22. By rotating the limiting sleeve 22 to remove it, the shock-absorbing spring 24 can be replaced. The shock-absorbing spring 24 with different elastic coefficients can be replaced according to the support weight to obtain anti-vibration components with different support weights, thus realizing the vibration damping installation of natural gas refueling equipment 3 with different weights.
[0028] The lower part of the outer wall of the telescopic sleeve 23 is provided with a retaining ring 25 that matches the inner diameter of the limiting sleeve 22. The top of the limiting sleeve 22 is provided with a limiting opening 26 that matches the outer diameter of the end of the telescopic sleeve 23. The limiting sleeve 22 and the telescopic sleeve 23 are in clearance fit. The telescopic sleeve 23 slides up and down in a directional manner within the limiting sleeve 22 through the retaining ring 25 and the limiting opening 26, which can ensure that the movement direction of the telescopic sleeve 23 will not be deviated, and the structure has good stability. The upper surface of the telescopic sleeve 23 is attached with a rubber pad 27. The rubber pad 27 is fixed to the telescopic sleeve 23 and achieves a soft connection between the vibration damping device 2 and the skid-mounted base 4 through the rubber pad 27, which plays a role in buffering and protecting the support surface.
[0029] The top of the telescopic sleeve 23 is provided with an exhaust hole 28, which can release pressure and exhaust air during the up and down movement of the telescopic sleeve 23. The bottom surface of the telescopic sleeve 23 is provided with an installation groove that matches the shape of the shock-absorbing spring 24 for installing the shock-absorbing spring 24.
[0030] The shock-absorbing spring 24 is a tower spring with a larger bottom and a smaller top. A tower spring is a type of shock-absorbing spring 24 that is small in size, has a large load capacity, and has variable stiffness characteristics. It is mainly used in scenarios where space is limited and high load capacity is required. Both the base 21 and the telescopic sleeve 23 are provided with spring seat stops 29 to facilitate the installation and positioning of the shock-absorbing spring 24. The spring seat stops 29 can limit the installation of the shock-absorbing spring 24.
[0031] The vibration damping device 2 is installed below the skid-mounted base 4 of the natural gas refueling equipment 3 and is evenly distributed around its perimeter, which can support and dampen the bottom perimeter of the natural gas refueling equipment 3.
[0032] The limiting sleeve 22 and telescopic sleeve 23 of the vibration damping device 2 are rotating parts, with general precision requirements and general materials, using round steel or general forgings; the rubber pad 27 and the shock-absorbing spring 24 are standard parts, which are easy to purchase or customize.
[0033] For the structural design of the anti-movement device 1, see [link to relevant documentation]. Figures 3 to 5 The anti-movement device 1 consists of a base plate 11, baffles, and stiffening plates 14. The baffles consist of baffle A12 and baffle B13, which are vertically arranged and welded to the base plate 11. The stiffening plates 14 are vertically welded between the base plate 11 and the baffles. The anti-movement device 1 is arranged at the four corners of the gas filling equipment. The baffles A12 and B13 can limit the gas filling equipment to prevent excessive displacement and ensure safe operation. The base plate 11 has screw mounting holes 15. The base plate 11 is fixed to the foundation with expansion screws that match the screw mounting holes 15. Installation and disassembly are convenient. When the gas filling equipment is moved, the expansion screws and anti-movement device 1 can be removed and reused, saving material costs and preventing construction waste from being left on site, thus avoiding environmental impact.
[0034] The aforementioned anti-movement device 1 is simple to manufacture and uses readily available materials. Its base plate 11, baffle A12, baffle B13, and stiffening plate 14 are all made from ordinary welded steel plates, posing no technical difficulties. It can be manufactured by grinding the welding bevel, drilling holes in the base plate 11, and assembling and welding them together.
[0035] If the baffles A12 and B13 are at a perfect 90° angle, there will be no margin after limiting the four corners of the equipment. During the operation of the equipment, the anti-movement device 1 may become loose or damaged due to the vibration of the equipment. Therefore, as a preferred solution, a limiting margin is left between the baffles A12 and B13, with an included angle of 92°. The angle design allows the gas filling equipment to be limited within the permissible offset range, which can not only ensure the safe operation of the equipment, but also reduce fatigue stress damage to the anti-movement device 1.
[0036] The above provides a detailed description of the anti-movement and anti-vibration device for a skid-mounted natural gas refueling equipment provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, based on the idea of this utility model, there will be changes in the specific implementation and application scope. Changes and improvements to this utility model are possible without exceeding the concept and scope specified in the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
