Description

Technical Field

[0001] The utility model relates to the technical field of rail transit, in particular to a foamed rubber rail bottom protection sleeve used for rail transit. Background Art

[0002] When a train moves from one track to another or wants to enter the track of a maintenance yard or a factory, special arrangements must be made on the track to guide the wheel flange to smoothly enter the designated track. This arrangement is called a turnout. The switch machine is a conversion device of the turnout, used to realize the conversion of the turnout, locking of the turnout and reflection of the position of the switch rail.

[0003] In the prior art, the switch machine is usually installed at the turnout manufacturer and transported to the use line as a whole. During the transportation process of the switch machine, due to bumps, the switch machine may collide, resulting in the switch machine shaking. The switch machine may lack buffer protection, causing the internal parts of the switch machine to become loose or damaged, thus reducing the service life of the switch machine. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the prior art, the switch machine is usually installed at the turnout manufacturer and transported to the use line as a whole. During the transportation process of the switch machine, due to bumps, the switch machine may collide, resulting in the switch machine shaking. The switch machine may lack buffer protection, causing the internal parts of the switch machine to become loose or damaged, thus reducing the service life of the switch machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a foamed rubber rail bottom protection sleeve used for rail transit, including: a protection sleeve body and a rubber shell, the rubber shell is fixedly installed on the outer surface of the protection sleeve body, and further includes:

[0006] A plurality of buffer airbag strips are equidistantly and fixedly installed at the bottom of the inner wall of the protection sleeve body. On both sides of the top of the protection sleeve body, a plurality of movable rods are equidistantly and movably embedded. One end of each of the plurality of movable rods is fixedly installed with a suction cup.

[0007] Preferably, the plurality of movable rods are evenly divided into two groups, and the outer surfaces of the two groups of movable rods are respectively movably embedded on both sides of the top of the rubber shell. Through the above setting, it is convenient for the movable rods to slide up and down.

[0008] Preferably, connecting plates are fixedly installed at one ends of the two groups of movable rods away from the suction cups, and buffer springs are movably sleeved on the outer surfaces of the plurality of movable rods. By applying an upward pulling force to the connecting plates, the buffer springs can be stretched.

[0009] Preferably, the multiple buffer springs are evenly divided into two groups. One ends of the two groups of buffer springs are respectively fixedly installed at the bottoms of two connecting plates, and the other ends of the two groups of buffer springs are respectively fixedly installed on both sides of the top of the rubber housing. Under the reset force of the buffer springs, the connecting plates can have a tendency to move downward, so that the suction cups are always in contact with the switch.

[0010] Preferably, square grooves are formed in the tops of the two connecting plates, and grips are movably embedded in the opposite sides of the inner walls of the two square grooves. Through the arrangement of the grips, it is convenient to pull the connecting plates.

[0011] Preferably, both sides of the top of the protective sleeve body are bent upward, and the protective sleeve body is made of foamed rubber. Through the above arrangement, the protective sleeve body can have a good buffer protection effect.

[0012] Preferably, a plurality of anti-slip grooves are equidistantly formed in the bottom of the rubber housing. Through the arrangement of the anti-slip grooves, the friction force at the bottom of the rubber housing can be increased, thereby avoiding the situation of the rubber housing sliding.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0014] 1. In the present utility model, by holding the grip with the hand and pulling upward, the movable rod and the suction cup are driven to move upward, and at the same time, the buffer spring is stretched. At this time, the switch is inserted into the inside of the protective sleeve body, and the grip is released. Under the reset force of the buffer spring, the connecting plate moves downward, synchronously driving the movable rod and the suction cup to move downward, so that the suction cup adsorbs on the top of the switch and exerts a certain degree of extrusion on the switch, which can prevent the switch from detaching from the protective sleeve body. In this way, when the switch bumps during transportation, through the action of the protective sleeve body and the buffer airbag strip, a good buffer effect can be achieved, and with the cooperation of the buffer spring, the buffer effect of the switch is further improved.

One end of each of the plurality of movable rods 4 is fixedly installed with a suction cup 6. The plurality of movable rods 4 are evenly divided into two groups. The outer surfaces of the two groups of movable rods 4 are respectively movably embedded on both sides of the top of the rubber housing 3. One end of the two groups of movable rods 4 away from the suction cup 6 is fixedly installed with a connecting plate 5. The outer surfaces of the plurality of movable rods 4 are all movably sleeved with buffer springs 7. The plurality of buffer springs 7 are evenly divided into two groups. One end of each of the two groups of buffer springs 7 is respectively fixedly installed on the bottom of the two connecting plates 5, and the other end of each of the two groups of buffer springs 7 is respectively fixedly installed on both sides of the top of the rubber housing 3. Square grooves 8 are opened on the tops of the two connecting plates 5. On the opposite sides of the inner walls of the two square grooves 8, handles 9 are movably embedded. Both sides of the top of the protection sleeve body 1 are bent upward. The protection sleeve body 1 is made of foamed rubber material, and a plurality of anti-slip grooves 10 are opened at equal intervals on the bottom of the rubber housing 3.

[0024] In this embodiment, by holding the grip 9 with hand and pulling upward, the movable rod 4 and the suction cup 6 are driven to move upward, synchronously stretching the buffer spring 7. At this time, the switch is inserted into the interior of the protective sleeve body 1, and the grip 9 is released. The connecting plate 5 moves downward under the restoring force of the buffer spring 7, synchronously driving the movable rod 4 and the suction cup 6 to move downward, so that the suction cup 6 adsorbs on the top of the switch and exerts a certain degree of extrusion on the switch, which can avoid the separation of the switch from the protective sleeve body 1. In this way, when the switch bumps during transportation, a good buffering effect can be achieved under the action of the protective sleeve body 1 and the buffer airbag strip 2, and with the cooperation of the buffer spring 7, the buffering effect of the switch is further improved. Moreover, through the setting of the anti-slip grooves 10, the friction force at the bottom of the rubber housing 3 can be increased, thus avoiding the sliding of the rubber housing 3. Rubber foaming uses natural rubber as the main body, is combined with other raw materials, and a specific foaming agent is added. After hot pressing and forming, the product is obtained. Different hardness foamed rubbers can be achieved by adjusting the proportion of the foaming agent.
