Detailed Description

It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the utility model. 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 utility model belongs.

Example 1:

In an exemplary embodiment of the present utility model, as shown in fig. 1 a-1 c, a cushioned energy consuming suspended track crash barrier is disclosed that includes a rolling assembly and a cushioned connection assembly.

The rolling assembly comprises a shaft body 3, a roller 1 and a buffer belt 2. The axle body 3 sets up a plurality ofly, and a plurality of axle bodies interval arrangement in proper order, and the cover is established a plurality of same quantity gyro wheels 1 on every axle body 3 in proper order, and gyro wheels 1 on the adjacent axle body 3 are through the buffer wheel area 2 cup joint connection that matches with it. Buffer wheel belts 2 sleeved on the rollers of the adjacent shaft bodies are arranged at intervals up and down, and the buffer wheel belts 2 on the two sides of the same shaft body 3 are arranged in a staggered mode. The circumferential edge of the roller 1 is provided with a rim protruding along the radial direction, a belt groove matched with a buffer belt is formed between the rims at the two sides of the roller 1, and the buffer belt is sleeved in the belt groove. The inner side of the roller 1 is provided with a shaft sleeve 4 which can be sleeved on the shaft body 3.

The cushion wheel belt 2 adopts a flexible endless belt so that it can play a role of cushioning when being impacted.

The upper end and the lower end of the shaft body 3 are respectively arranged on the structural object through buffer connection components and tension the buffer wheel belt 2 on the shaft body 3 to form a grid protection surface which is rich in elasticity, can slide and roll.

The buffer connection assembly consists of a U-shaped chute type connecting piece 11, a spring 12 and a spring mounting rod 13. The U-shaped chute type connecting piece 11 is of a U-shaped structure, hanging lugs are arranged on two sides of the U-shaped structure, and the hanging lugs on two sides of the U-shaped chute type connecting piece 11 are fixed on a structural object through bolts 16; the structure in this embodiment is a crash wall 41.

The shaft body 3 is vertically arranged, the upper end and the lower end of the shaft body 3 are respectively penetrated in the U-shaped sliding grooves of the U-shaped sliding groove type connecting piece 11, the end part of the shaft body 3 is provided with a preformed hole along the radial direction, the U-shaped structure of the U-shaped sliding groove type connecting piece 11 is also provided with a preformed hole, and the spring mounting rod 13 penetrates the shaft body 3 and the preformed hole of the U-shaped sliding groove type connecting piece 11 and is connected with the nut 15, so that the shaft body 3 and the U-shaped sliding groove type connecting piece 11 are connected together.

The spring 12 is sleeved on the rod shaft of the spring mounting rod 13, the spring 12 and the spring mounting rod 13 are transversely arranged in a transverse U-shaped chute of the U-shaped chute type connecting piece 11, and the end part of the spring mounting rod 13 is supported on a structural object. The sum of the minimum length of the compressed spring 12 and the radius of the shaft body 3 is larger than the distance from the center of the roller 1 to the outer edge of the buffer wheel belt 2, when the guardrail is impacted or pushed, the shaft body 3 translates along the U-shaped sliding groove of the U-shaped sliding groove connecting piece 11 and the spring mounting rod 13 to compress the spring 12 for buffering, and even if the spring 12 is compressed to the minimum length, the roller 1 or the buffer wheel belt 2 can be ensured to freely roll without contact with the anti-collision wall 41.

The working principle of the anti-collision guardrail is as follows:

When the moving object collides with the guardrail, the moving object drives the buffer wheel belt 2 on the collision surface to drive the roller 1 sleeved with the buffer wheel belt to independently roll around the shaft body 3, and pushes the shaft body 3 to compress the spring 12 to absorb impact energy, so that the buffer wheel belt 2 which is not contacted with the moving object does not participate in rolling, and the sliding resistance of the collision surface is reduced. Because the buffer wheel belt 2 can slide and deform to absorb energy and the shaft body 3 compresses the spring 12 to absorb energy, the impact force and the sliding resistance of a collided object are reduced to a great extent, the buffer effect is greatly improved, and the damage degree of a vehicle is reduced.
