Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbers, and particularly relates to a rubber shock absorber for subways. Background Art

[0002] As a kind of urban rail vehicle, with the development of life, the requirements for its supporting facilities are getting higher and higher. As an important component of train vehicles, shock absorbers play a role in maintaining running safety and riding comfort during train operation.

[0003] According to a publicly disclosed rubber shock absorber for subways (Publication No.: CN 217328246 U), it includes a lower plate, an upper plate and rubber. The two sides of the lower plate are bent upward twice to form a U-shaped structure. The two sides of the upper plate are bent downward twice to form an L-shaped structure. The L-shaped structure is located inside the U-shaped structure. The rubber is located inside the U-shaped structure and vulcanized and formed by wrapping the L-shaped structure. The lower surface of the L-shaped structure of the upper plate does not contact the top surface of the lower plate. In the above application, through the settings of the upper plate and the lower plate, the two sides of the upper plate and the lower plate are fixed by vulcanizing and forming after being staggered through the U-shaped structure and the L-shaped structure. The distance between the upper plate and the lower plate limits the maximum sinking amount. And after the lower plate is fixed, the upper plate can be pulled and pressed. After the rubber completely falls off, it is very difficult for the upper plate and the lower plate to separate, with high safety and a simple overall structure, which is convenient for installation. However, the shock absorption effect in the above application is single, and bolts are required for installation and fixation. The bolts are prone to falling off after long-term use, and the practicability is not strong. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rubber shock absorber for subways, which solves the existing problems through a fixing device and a shock absorption device.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a rubber shock absorber for subways, including a fixing block, and a fixing device and a shock absorption device are arranged on the fixing block;

[0007] The fixing device includes an airbag. An air inlet pipe and an air delivery pipe are fixedly connected to the top of the airbag.

The pressure rod is fixedly connected to a fixing plate on the side far away from the pressure chamber. An exhaust valve is arranged on the side of the pressure chamber far away from the pressure rod.

[0008] Furthermore, the inside of the fixing block is in a hollow state. The material of the fixing block is high-strength metal steel, and the fixing block can be effectively fixed to the track.

[0009] Furthermore, the airbag is fixedly connected to the bottom of the fixed block, and the air pressure chamber is arranged on both outer sides of the fixed block. After being squeezed, the airbag can effectively transport the internal gas to the inside of the air pressure chamber through the air delivery pipe.

[0010] Furthermore, the fixing plate is made of alloy steel, and the fixing plate is arranged on the inner side of the lower end of the fixed block. The fixing plate can effectively fix both sides of the track.

[0011] Furthermore, the shock absorption device includes a buffer rubber. Both sides of the lower end of the buffer rubber are rotatably and penetratingly connected with rotating rods. Deceleration wheels are fixedly connected to both sides of the rotating rods. An elastic support rod is fixedly connected to the bottom of the buffer rubber. The shock absorption device can effectively shock-absorb the subway.

[0012] Furthermore, the buffer rubber is shaped like a T, and the buffer rubber is slidably connected to the inner wall of the fixed block. The buffer rubber can effectively conduct preliminary buffering on the subway.

[0013] Furthermore, the deceleration wheel is made of rubber with strong friction. The elastic support rod is fixedly connected to the inner side of the upper end of the fixed block. The deceleration wheel can rub against the inner wall of the fixed block to generate resistance and enhance the shock absorption effect.

[0014] The utility model has the following beneficial effects:

[0015] Through the fixing device of the utility model, when installing the fixed block, the airbag can be squeezed by the track. The airbag will transport the internal gas to the inside of the air pressure chamber through the air delivery pipe.

The operation is simple, time-saving and labor-saving, and the practicability is relatively strong.

[0016] Through the shock absorption device of the utility model, during the running of the subway, the buffer rubber can conduct preliminary buffering on the subway. When the buffer rubber is squeezed by the subway, the buffer rubber will contract under the action of the squeezing force and the elastic support rod. During the contraction of the buffer rubber, it will drive the deceleration wheel to rub against the inner wall of the fixed block to generate resistance and enhance the shock absorption effect, further enhancing the practicability of the whole device.

[0031] The fixing plate 26 is made of alloy steel. The fixing plate 26 is arranged on the inner side of the lower end of the fixed block 1. The fixing plate 26 can effectively fix both sides of the track.

[0032] The shock absorption device 3 includes a buffer rubber 31. Rotating and penetrating connections are provided on both lower sides of the buffer rubber 31 with a rotating rod 32. Fixed connections are provided on both sides of the rotating rod 32 with a reduction wheel 33. A resilient support rod 34 is fixedly connected to the bottom of the buffer rubber 31. The shock absorption device 3 can effectively shock-absorb the subway.

[0033] The buffer rubber 31 is shaped like a T. The buffer rubber 31 is slidably connected to the inner wall of the fixed block 1. The buffer rubber 31 can effectively provide a preliminary buffer for the subway.

[0034] The reduction wheel 33 is made of rubber with strong friction. The resilient support rod 34 is fixedly connected to the inner side of the upper end of the fixed block 1. The reduction wheel 33 can rub against the inner wall of the fixed block 1 to generate resistance and enhance the shock absorption effect.

[0035] Through the fixing device 2 of the present utility model, when installing the fixed block 1, the airbag 21 can be squeezed by the track. The airbag 21 will transport the internal gas to the inside of the air pressure chamber 24 through the air delivery pipe 23. The air pressure chamber 24 will drive the air pressure rod 25 and the fixing plate 26 to move to fix both sides of the track.

The pressure rod 25 and the fixed plate 26 will return to their original positions, releasing the fixed state of both sides of the track. After removing the fixed block 1, the airbag 21 will no longer be squeezed, and the airbag 21 will allow external gas to enter its interior through the air inlet pipe 22 to restore its inflated state, facilitating the next use. It has strong practicability. After the fixed block 1 is installed, when the subway passes through the track, it will squeeze the buffer rubber 31. The buffer rubber 31 will initially buffer the subway. Under the action of the extrusion force and the elastic support rod 34, the buffer rubber 31 will contract. While the buffer rubber 31 contracts, it will drive the deceleration wheel 33 to move synchronously. The deceleration wheel 33 will rub against the inner wall of the fixed block 1 to generate resistance and enhance the damping effect. After the subway passes, the elastic support rod 34 will drive the above structure to return to its original position, facilitating the next use, further enhancing the practicability of the entire device.
