Problems solved by technology

[0004] (1) The protrusions, grooves or holes on the base are arranged in a staggered manner, but they are basically discontinuously arranged, and the backing plate has insufficient resilience, and under different loads (axle loads), due to the protrusions, The surfaces formed by grooves or holes are on the same horizontal plane, and the existing elastic backing plate has a single vertical stiffness, which is difficult to meet the needs of railway transportation
[0005] (2) The protrusions, grooves or holes of the existing elastic backing plate are designed in an isolated way. Under the action of vertical or lateral load, the transverse and longitudinal rigidity is small, which is easy to produce relative slippage and accelerate the wear of the backing plate. Fasteners The buckle pressure drops, which in turn leads to the loosening of the fasteners, which affects the vibration damping performance and service life of the track system
[0015] Although the above-mentioned patents all involve elastic backing plates, none of the above-mentioned patents involves how to improve the structure of the interlaced connection between the reinforcing ribs and the protrusions, so there is still too little horizontal stiffness and insufficient rebound strength, which is likely to cause the rails and iron pads to be damaged. The board slides laterally, which accelerates the lack of wear and tear, so it still needs to be further improved

Embodiment 1

[0047] Such as figure 1 , figure 2 with image 3 As shown, a reinforcing rib reinforced elastic pad includes a plate body 1; there are protrusions 2 on the upper and lower surfaces of the plate body 1, and the protrusions 2 are truncated cones; in the horizontal and vertical directions of the protrusions 2 There are stiffeners 3 arranged, which are horizontal stiffeners and vertical stiffeners; the shape of the stiffeners 3 is a discontinuous strip, and the two ends of the length direction of the stiffeners 3 are connected with two protrusions 2 respectively, and horizontal and vertical The length line of the ribs in the two directions passes through the center of the protrusion 2, so that the protrusion 2 is pulled and connected by four symmetrical ribs in the horizontal and vertical directions, and the horizontal and vertical ribs are interlaced and connected to each other. The "cross"-shaped reinforcing ribs are combined with the protrusions 2 to form a mesh-like elasticity ...

Embodiment 2

[0052] Such as Figure 4 , Figure 5 with Image 6 As shown, a reinforcing rib reinforced elastic backing plate includes a plate body 201; there are protrusions 202 on the upper and lower surfaces of the plate body 201, and the protrusions 202 are truncated cones; the protrusions 202 are arranged obliquely and symmetrically. 4 stiffeners 203, and 4 stiffeners 203 are perpendicular to each other; the shape of the stiffener 3 is a discontinuous strip, and the two ends of the longitudinal direction of the stiffener 203 are respectively connected to two protrusions 202, and are diagonal The line connecting the ribs in the two directions in the length direction passes through the center of the protrusion 202, so that the protrusion 202 is connected by symmetrical 4 ribs in the four directions; the 4 ribs and the protrusion 202 form a mesh The mesh structure elasticity enhancer, through the mesh structure elasticity enhancer, enhances the resilience of the elastic pad and the ability ...

Embodiment 3

[0056] Such as Figure 7 , Figure 8 with Picture 9 As shown, a reinforcing rib reinforced elastic backing plate includes a plate body 301; there are protrusions 302 on the upper and lower surfaces of the plate body 301, and the protrusions 302 are truncated; in the peripheral gap between the protrusions 302 A continuous reinforcing rib 303 is arranged obliquely. The reinforcing rib 303 surrounds the periphery of the protrusion 302, and the reinforcing rib 303 is connected with 4 edges of the periphery of the protrusion 302 to form a "mouth"-shaped annular reinforcing rib around the protrusion 302. "" shaped ring-shaped stiffeners are pulled at four points in two directions to enhance the horizontal rigidity and rebound strength of the elastic pad; the ring-shaped stiffeners and protrusions 302 form a net-like mesh structure elastic reinforcement, through the net-like structure The elastic enhancer enhances the resilience of the elastic pad and the ability to resist horizontal...

Abstract

The invention relates to a method using reinforcing ribs to enhance rebound force of an elastic cushion board, and the elastic cushion board; the elastic cushion board is uniformly provided with bosses; reinforcing ribs are uniformly arranged around the bosses on the board; the reinforcing rib is connected with the periphery of the boss on the board, thus forming a net structure elasticity enhance body; the net structure elasticity enhance body can enhance the elastic cushion board rebound force and anti-transverse horizontal deformation ability, and can prevent an iron cushion board to have lateral sliding; under a normal load effect, the elastic cushion board is in a basic bearing mode: stretching, shearing, deflection and proper amount of compression are integrated to provide the elastic force; under a large load or limit load effect, the elastic cushion board can automatically convert into an enhanced bearing mode from the basic bearing mode: the reinforcing rib bearing area gradually increases, and the cushion board vertical rigidity automatically increases in a non-linear manner. The elastic cushion board can prevent wearing damages caused by lateral sliding between a railway and the iron cushion board, and is widely applied to the rail transit system.

Description

Technical field [0001] The invention relates to a method and a device for improving the elasticity of an elastic element, in particular to a method and a device for enhancing the resilience of an elastic pad through a reinforcing rib for a rail transit system, and belongs to the technical field of rail transit. Background technique [0002] In order to solve the serious uneven distribution of domestic resources and meet the needs of social and economic development, in recent years, heavy-duty railways have developed rapidly, and the demand for track fastener systems has also increased. With the increase of railway operation speed and load weight , The wheel-rail dynamic effect is intensified, and the load-bearing conditions of the track fastener system are getting worse and worse. How to effectively extend the life of the fastener system under the premise of meeting the requirements of track strength has become a major technical problem. [0003] The elastic pad is one of the most...
