[0002] When a train switches from one track to another or enters a maintenance yard or factory, a special arrangement must be made on the track to guide the wheel flanges smoothly into the designated track. This arrangement is called a turnout. A switch is a turnout switching device used to switch, lock, and indicate the position of the turnout switch rail.

[0003] A search revealed that Chinese Patent Publication No. CN211010744U discloses a thermoplastic polyester elastomer pad, comprising a pad body, a pad layer disposed on the inner surface of the pad body, an arc-shaped surface disposed on the lower outer surface of the pad layer, a friction surface disposed on the upper outer surface of the pad layer, a fixing plate disposed on the upper outer surface of the pad body, a limiting mechanism disposed on the side of the upper outer surface of the pad body near the fixing plate, and a fixing bolt disposed on the side of the upper outer surface of the pad body near the limiting mechanism. This thermoplastic polyester elastomer pad can prevent objects from sliding on the upper outer surface of the pad body, can stably fix the pad, and can prevent objects placed on the upper outer surface of the pad body from getting damp.

[0004] However, in the existing technology, switch devices are usually installed by the turnout manufacturer and transported as a whole to the line of use.

A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

In addition, the No. 1 and No. 2 through holes opened in the middle of the No. 1 and No. 2 buffer plates can disperse the impact force when the No. 1 and No. 2 buffer plates are subjected to force. In this way, the device can effectively buffer the impact force generated by the bumps encountered during transportation, and prevent the switch from being damaged by bumps and affecting normal use.

When encountering bumps during transportation, the first and second buffer bends set between the first and second buffer plates will deform under force. The bending deformation of the first and second buffer bends can effectively buffer the impact force generated by the bumps. The third buffer bend between the fixing plate and the mounting plate will also effectively buffer the impact. This is to prevent the switch from being damaged by the failure of the mounting plate to buffer when the switch moves left and right under force. In addition, the first and second through holes in the middle of the first and second buffer plates can disperse the impact force when the first and second buffer plates are under force. In this way, the device can effectively buffer the impact force generated by the bumps encountered during transportation, and prevent the switch from being damaged by bumps and affecting normal use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 4 As shown, one embodiment of this utility model includes a first buffer plate 1, a second buffer plate 6 below the first buffer plate 1, first buffer curved plates 10 on both sides of the lower end of the first buffer plate 1, second buffer curved plates 9 on one side of each of the two first buffer curved plates 10, first grooves 11 evenly opened on one side of each of the two first buffer curved plates 10, second grooves 12 evenly opened on one side of each of the two second buffer curved plates 9, first through holes 8 evenly opened in the middle of the first buffer plate 1, second through holes 7 evenly opened in the middle of the second buffer plate 6, mounting plates 2 fixedly connected to the four sides of the upper end of the first buffer plate 1, fixing plates 4 on one side of each of the four mounting plates 2, third buffer curved plates 3 evenly fixedly connected to one side of each of the four fixing plates 4, and the other ends of the four third buffer curved plates 3 respectively fixedly connected to one side of each of the four mounting plates 2.

[0033] In this embodiment, when transporting the switch, it can be placed on the first buffer plate 1, and the fixing plates 4 around it can fix the switch around its perimeter. When encountering bumps during transportation, the first buffer bend plate 10 and the second buffer bend plate 9 set between the first buffer plate 1 and the second buffer plate 6 will deform after being subjected to force. The bending deformation of the first buffer bend plate 10 and the second buffer bend plate 9 can effectively buffer the impact force generated by the bump. The third buffer bend plate 3 between the fixing plate 4 and the mounting plate 2 also... This device effectively buffers the impact, preventing damage to the switch caused by the mounting plate 2 failing to provide cushioning when the switch moves left and right under force. Furthermore, the through holes 8 and 7 in the middle of the first and second buffer plates 1 and 6 can disperse the impact force when the first and second buffer plates 1 and 6 are under force. This method allows the device to effectively buffer the impact force generated by the bumps encountered during the transportation of the switch, preventing the switch from being damaged by collisions and affecting its normal use.

[0034] Example 2, as Figures 1 to 4 As shown, both ends of the two No. 1 buffer bends 10 are fixedly connected to connecting plates 13, and one side of each of the four connecting plates 13 is fixedly connected to a No. 1 buckle 14. Both ends of the two No. 2 buffer bends 9 are fixedly connected to No. 2 buckles 15. No. 1 slots 18 are opened on both sides of the No. 1 buffer plate 1, No. 2 slots 17 are opened on both sides of the lower end of the No. 1 buffer plate 1, No. 3 slots 19 are opened on both sides of the No. 2 buffer plate 6, and No. 4 slots 16 are opened on both sides of the upper end of the No. 2 buffer plate 6. Among them, the two No. 1 buckles 14 are fixedly connected to connecting plates 13, and one side of each connecting plate 14 is fixedly connected to a No. 1 buckle 14. The outer surface of buckle 14 is slidably engaged with the interior of two first slots 18, and the outer surface of the other two first buckles 14 is slidably engaged with the interior of two third slots 19, the two second buckles 15 are slidably engaged with the interior of two second slots 17, and the other two second buckles 15 are slidably engaged with the interior of two fourth slots 16. The lower end of the second buffer plate 6 is evenly provided with first anti-slip texture 21, and the four fixing plates 4 are evenly provided with second anti-slip texture 20 on one side.

[0035] In this embodiment, by setting a first buckle 14 and a second buckle 15 at both ends of the first buffer bend plate 10 and the second buffer bend plate 9 respectively, the first buffer bend plate 10 and the second buffer bend plate 9 can be removed from the first buffer plate 1 and the second buffer plate 6. By opening a first groove 11 and a second groove 12 on the side of the first buffer bend plate 10 and the second buffer bend plate 9, different static stiffness indicators of the device can be achieved by replacing the first buffer bend plate 10 and the second buffer bend plate 9 with different numbers of first grooves 11 and second grooves 12. Moreover, the entire device is made of polyester elastomer, which can be recycled and reused while ensuring its deformation elasticity, which is conducive to environmental protection.

[0036] Working Principle: When transporting the switch, it can be placed on the first buffer plate 1. The fixing plates 4 around the switch can fix it around its perimeter. When encountering bumps during transportation, the first buffer bend plate 10 and the second buffer bend plate 9 set between the first buffer plate 1 and the second buffer plate 6 will deform under force. The bending deformation of the first buffer bend plate 10 and the second buffer bend plate 9 can effectively buffer the impact force generated by the bump. The third buffer bend plate 3 between the fixing plate 4 and the mounting plate 2 will also effectively buffer the impact. This is to prevent the switch from being damaged by the failure of the mounting plate 2 to buffer when the switch moves left and right under force. The first through hole 8 and the second through hole 7 opened in the middle of the buffer plate 1 and the second buffer plate 6 can disperse the impact force when the buffer plate 1 and the second buffer plate 6 are subjected to force. By setting the first buckle 14 and the second buckle 15 at both ends of the first buffer bend plate 10 and the second buffer bend plate 9 respectively, the first buffer bend plate 10 and the second buffer bend plate 9 can be removed from the first buffer plate 1 and the second buffer plate 6. By opening the first groove 11 and the second groove 12 on the side of the first buffer bend plate 10 and the second buffer bend plate 9, different static stiffness indicators of the device can be achieved by replacing the first buffer bend plate 10 and the second buffer bend plate 9 with different numbers of first groove 11 and second groove 12.
