Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit or scope of the invention, which is therefore not limited to the specific embodiments disclosed below.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1, in one embodiment, the anti-collision buffer device is used for being installed on a circular infrastructure such as a circular pier 10 to protect the circular infrastructure. Specifically, the crash cushion apparatus includes a casing 100 and a link 200.
The casing 100 includes a casing inner shell 110 and a casing outer shell 120, wherein the casing inner shell 110 is used for being sleeved on a circular foundation device, such as the circular pier 10. The diameter of the casing outer shell 120 is larger than that of the casing inner shell 110, and the casing outer shell 120 is sleeved outside the casing inner shell 110. In an embodiment, the outer casing 120 and the inner casing 110 are made of steel composite materials, so as to improve the anti-collision buffering capacity of the anti-collision buffering device.
The two ends of the connection rod 200 are connected with the casing outer case 120, and connection points of the two ends of the connection rod 200 with the casing outer case 120 are located at different points in the circumferential direction of the casing outer case 120, and the middle part of the connection rod 200 is in contact with the casing inner case 110. The number of the links 200 is at least three, and at least three links 200 are uniformly arranged in the circumferential direction of the box housing 120, so that the box housing 120 can be supported and the overall impact can be resisted.
Wherein, the connecting rod 200 and the sleeve case 120 between the two ends thereof form an arc shape, and the corresponding connecting rod 200 can be extruded by the front impact of the sleeve case 120, just like an internal pressure bowstring, so that the impact energy can be greatly buffered and absorbed. For non-frontal impacts, in addition to a portion of the impact component being cushioned and released as a frontal impact, the lateral component is released by torsion of the boot housing 120 and the linkage 200 relative to the center of the circle.
In one embodiment, the number of the connecting rods 200 is four, the four connecting rods 200 are mutually perpendicular and enclose a rectangle, and the four connecting rods 200 form four sides of the rectangle. The linkage rod 200 is horizontally disposed, and the linkage rod 200 is perpendicular to the axis of the box housing 120. The middle part of the connecting rod 200 is tangent to the inner casing 110 of the box, so that the torsion of the outer casing 120 of the box and the connecting rod 200 is facilitated during non-frontal collision, and the buffering energy consumption effect is improved.
In one embodiment, the connecting rod 200 may be made of a material having an extremely strong tensile property, such as a magnesium alloy material, etc., to ensure deformation and elongation of the connecting rod 200. The two ends of the connecting rod 200 are hinged with the box casing 120, so that the connection part of the connecting rod 200 and the box casing 120 is prevented from being easily disconnected, and the flexibility of impact deformation is improved. The middle part of the connecting rod 200 is hinged with the inner shell 110 of the sleeve box, in the front collision process, the connecting rod 200 of the sleeve box 100 close to the collision point is like a pressing string, and the connecting rod 200 on the other side is like a pulling string, so that bidirectional buffering energy consumption is realized, and the anti-collision buffering performance of the device is improved.
Referring to fig. 2, in one embodiment, the connecting rods 200 are provided with multiple layers along the axial direction of the casing 120, wherein the connecting rods 200 of two adjacent layers are offset from each other, so that the surface of the casing 120 uniformly buffers the impact. The outer wall of the casing 120 is provided with a flexible protection layer 130, and the flexible protection layer 130 is used for protecting the casing 120, avoiding the casing 120 from being scrapped after being impacted and requiring frequent replacement. In particular, flexible protective layer 130 may be a rubber pad.
In one embodiment, a cushioning filler is filled between the outer casing 120 and the inner casing 110, and the cushioning filler can assist in cushioning an impact. Meanwhile, the buffer filler can provide a certain support for the box casing 120, so that the box casing 120 is prevented from being damaged by impact. Specifically, the cushion filler may be foam or a cushion ring, or the like.
Above-mentioned anticollision buffer, based on the circular outline characteristic of facilities such as circular pier 10, the adaptability is better, and the structure is also simpler, can be bigger the improvement to the anticollision protection of facilities such as circular pier 10, application prospect is wide.
