[0021] This invention first involves breaking open the entire body of the polyester elastomer rail bottom protective sleeve and fitting it onto the outer surface of the switch track, ensuring the hollow groove is securely fitted. The entire body of the polyester elastomer rail bottom protective sleeve is made of polyester elastomer, allowing for rapid mass production through injection molding, compression molding, and extrusion. The raw material is thermoplastic and recyclable, enhancing the environmental friendliness of the sleeve. During production, the outermost polyurethane layer provides excellent elasticity and wear resistance. The ordinary polyethylene layer protects the track surface from friction and wear, absorbs impacts, reduces direct impact force, resists environmental erosion, extends service life, and provides good corrosion resistance, reducing noise from collisions. Simultaneously, the silicone layer within the polyester elastomer rail bottom protective sleeve exhibits high elasticity and flexibility, effectively absorbing and dispersing impacts. The silicone layer is designed to withstand impacts, reducing wear and damage to tracks and vehicles. It possesses impact resistance, rapidly recovering its shape upon strong impact, providing stable protection and preventing structural damage from impacts. The silicone layer maintains stable performance at extreme temperatures, resisting hardening or softening, adapting to different climatic conditions. Its soft nature allows it to adhere tightly to the track surface, filling gaps and further enhancing protection. The microstructure of the polymer microsphere layer effectively absorbs and disperses impact forces, reducing direct impact on the track and providing additional cushioning protection. The high-density polyethylene (HDPE) layer's high strength and toughness allow it to withstand significant impacts, protecting the track from damage. Furthermore, the number of grooves on the bottom of the polyester elastomer rail base protective sleeve allows for different static stiffness indices, providing comprehensive protection for the switch track. This ensures the switch track receives adequate protection during transport, preventing bumps and impacts and improving the overall quality of the switch track.

[0022] This invention, to prevent the polyester elastomer rail base protective sleeve from swaying left and right, involves workers first securing two fixing plates to the transport vehicle through multiple threaded holes on their surfaces. Then, the polyester elastomer rail base protective sleeve and the switch track are placed between the two fixing plates. When the switch track and the polyester elastomer rail base protective sleeve sway left and right, multiple buffer plates contact both sides of the polyester elastomer rail base protective sleeve surface and transmit the vibration to the dampers and springs via sliding plates. The dampers and springs utilize their properties to absorb and buffer the vibration. The dampers effectively reduce vibration and improve stability and comfort by absorbing and dissipating vibration energy. The springs absorb and mitigate impact, reducing the impact of vibration and shock on the equipment and structure, improving comfort and protection. Simultaneously, the sliding plates move along with the dampers and springs within the hollow column, thus mitigating lateral swaying during transport. This shock-absorbing structure, compatible with the polyester elastomer rail base protective sleeve, provides effective lateral vibration damping for the switch track, enhancing the practicality of the rail base protective sleeve.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Example 1, please refer to Figures 1-4 This utility model provides a technical solution: a polyester elastomer rail bottom protective sleeve for rail transit, including a polyester elastomer rail bottom protective sleeve body 1, and two fixing plates 2. The bottom of the polyester elastomer rail bottom protective sleeve body 1 has multiple grooves 101, and the inner wall of the polyester elastomer rail bottom protective sleeve body 1 has hollow grooves 102. The polyester elastomer rail bottom protective sleeve body 1 is composed of a polyurethane layer 103, a common polyethylene layer 104, a silicone layer 105, a polymer microsphere layer 106, and a high-density polyethylene layer 107.

A vertical plate 203 is fixedly connected to one side of the outer surface of the two inclined plates 202. The bottom of the vertical plate 203 is fixedly connected to the top edge of the fixed plate 2, and two hollow columns 204 are fixedly connected to one side of the outer surface of the vertical plate 203.

[0031] In this embodiment, the polyester elastomer rail bottom protective sleeve body 1 is first broken open and fitted onto the outer surface of the switch track, so that the hollow groove 102 is firmly fitted onto the outer surface of the switch track. The polyester elastomer rail bottom protective sleeve body 1 is made entirely of polyester elastomer, which can be mass-produced through injection molding, compression molding, and extrusion molding, which is very fast. The raw material is a thermoplastic material that can be recycled and reused, which helps to enhance the environmental friendliness of the polyester elastomer rail bottom protective sleeve body 1. During the production of the polyester elastomer rail bottom protective sleeve body 1, the outermost polyurethane layer 103 gives the polyester elastomer rail bottom protective sleeve body 1 good elasticity and wear resistance. The ordinary polyethylene layer 104 can protect the track surface from friction and wear, facilitate impact absorption, reduce the direct impact force of impact on the track, resist the erosion of the track by environmental factors, extend the service life, have good corrosion resistance, and reduce noise caused by collision. At the same time, the silicone layer 105 in the polyester elastomer rail bottom protective sleeve body 1 has high elasticity and flexibility, which can effectively absorb and decompose. The silicone layer 105 disperses impact force, thereby reducing wear and damage to the track and vehicle. It possesses impact resistance, rapidly recovering its shape after a strong impact, providing stable protection and preventing structural damage caused by impact. The silicone layer 105 maintains stable performance at extreme temperatures, resisting hardening or softening, adapting to different climatic conditions. Its soft nature allows it to adhere tightly to the track surface, filling gaps and further enhancing protection. The microstructure of the polymer microsphere layer 106 effectively absorbs and disperses impact force, reducing direct impact on the track and providing additional cushioning protection. The high-density polyethylene layer 107, with its high strength and toughness, allows the HDPE layer to withstand significant impact, protecting the track from damage. Simultaneously, the number of grooves 101 at the bottom of the polyester elastomer rail base protective sleeve body 1 allows for different static stiffness indices, thus providing better protection for the switch track. This ensures that the switch track has good protection during overall transportation, preventing bumps and collisions and improving the overall quality of the switch track.

[0033] In this embodiment, to prevent the polyester elastomer rail base protective sleeve body 1 from swaying left and right, the workers first securely fix two fixing plates 2 to the transport car through multiple threaded holes 201 on their surfaces. Then, the polyester elastomer rail base protective sleeve body 1 and the switch rail are placed between the two fixing plates 2. When the switch rail and the polyester elastomer rail base protective sleeve body 1 sway left and right, multiple buffer plates 205 begin to contact both sides of the surface of the polyester elastomer rail base protective sleeve body 1, and transmit the vibration to the damper 208 and spring 207 through the slider plate 206. The damper 208 and spring 207 then... The damper 208 absorbs and dissipates vibration energy, effectively reducing vibration and improving stability and comfort. The spring 207 absorbs and mitigates impact force, reducing the impact of vibration and impact on equipment and structure, improving comfort and protection performance. Meanwhile, the slider plate 206 moves with the movement of the damper 208 and spring 207 in the hollow column 204, thus preventing lateral swaying during transportation. It has a shock-absorbing structure that matches the polyester elastomer rail bottom protective sleeve body 1, which can effectively dampen the left and right sides of the switch track, improving the practicality of the rail bottom protective sleeve.

[0034] Working Principle: In use, the polyester elastomer rail base protective sleeve body 1 is first broken open and placed on the outer surface of the switch track, ensuring the hollow groove 102 is securely fitted onto the outer surface of the switch track. The polyester elastomer rail base protective sleeve body 1 is made entirely of polyester elastomer, allowing for rapid mass production through injection molding, compression molding, and extrusion. The raw material is thermoplastic, making it recyclable and enhancing the environmental friendliness of the polyester elastomer rail base protective sleeve body 1. During production, the outermost polyurethane layer 103 provides the polyester elastomer rail base protective sleeve body 1 with excellent elasticity and wear resistance. The ordinary polyethylene layer 104 protects the rail... The track surface is protected from friction and wear, facilitating impact absorption, reducing the direct impact force on the track, resisting environmental erosion, extending service life, and exhibiting good corrosion resistance. It also reduces noise generated by collisions. Simultaneously, the silicone layer 105 in the polyester elastomer track bottom protective sleeve body 1 possesses high elasticity and flexibility, effectively absorbing and dispersing impact force, thereby reducing wear and damage to the track and vehicle. It is impact-resistant, rapidly recovering its shape after a strong impact, providing stable protection and preventing structural damage caused by impacts. The silicone layer 105 maintains stable performance at extreme temperatures, does not easily harden or soften, adapting to the needs of use under different climatic conditions, and its soft nature allows it to conform to the track surface. The surface is tightly bonded, filling gaps and further enhancing the protective effect. The microstructure of the polymer microsphere layer 106 effectively absorbs and disperses impact forces, reducing direct impact on the track and providing additional cushioning protection. The high-density polyethylene layer 107, with its high strength and toughness, allows the HDPE layer to withstand greater impact forces, protecting the track from damage. Simultaneously, the number of grooves 101 on the bottom of the polyester elastomer rail bottom protective sleeve body 1 can achieve different static stiffness indices, thus providing better protection for the switch track. This ensures that the switch track has good protection measures during overall transportation, preventing bumps and collisions, improving the overall quality of the switch track, and further protecting it from damage. As the circuit sways from side to side, the workers first securely fix two fixing plates 2 to the transport car through multiple threaded holes 201 on their surfaces. Then, the polyester elastomer rail base protective sleeve body 1 and the switch rail are placed between the two fixing plates 2. When the switch rail and the polyester elastomer rail base protective sleeve body 1 sway from side to side, multiple buffer plates 205 begin to contact both sides of the surface of the polyester elastomer rail base protective sleeve body 1, and transmit the vibration to the damper 208 and spring 207 through the slider plate 206. The damper 208 and spring 207 absorb and buffer the vibration. The damper 208 absorbs and dissipates vibration energy, effectively reducing vibration and improving stability and comfort. The spring 207 absorbs and reduces impact force.This reduces the impact of vibration and shock on equipment and structures, improving comfort and protective performance. Simultaneously, the slider plate 206 moves within the hollow column 204 along with the damper 208 and spring 207, thus mitigating lateral swaying during transport. It features a shock-absorbing structure compatible with the polyester elastomer rail base protective sleeve body 1, effectively reducing lateral vibration of the switch track and enhancing the practicality of the rail base protective sleeve.
