Example Embodiment
[0067] Example one
[0068] Such as figure 1 , figure 2 The track elastic fixing device of the present invention shown includes a base 1 made of cast steel material, and in addition, it also includes a guide assembly and a vertical support element. The guide assembly includes a guide element 3 and a guide bracket 2 on both sides of the rail waist of the rail 9. The guide bracket 2 is provided with a position adjustment bolt 5. The guide element 3 is pressed against the rail waist surface of the rail 9 through a pressure plate 4 and a position adjustment bolt 5. Among them, two guide brackets 2 are provided, which are made of the same material as the base 1 and cast into one body; the guide element 3 is made of elastic polyurethane material, and the guide element is in close contact with the rail at the waist part of the rail 9 and supports vertically. The element is composed of a metal spring. In the figure, the metal disc spring 7 is specifically located under the rail 9 and ha...
Example Embodiment
[0076] Example two
[0077] Such as image 3 , Figure 4 The difference between the track elastic fixing device of the present invention and the first embodiment is that the guide assembly includes a guide bracket 2 cast integrally with the base 1 and a detachable guide bracket 2a, wherein the guide bracket 2a uses fasteners 13 Fixed on the base 1. Since a detachable guide bracket 2a is provided, the track elastic fixing device of the present invention can be easily assembled with the rail 9 and adjusted relative position, so the guide brackets 2 and 2a are directly used to press the guide element 3 on the rail waist. The mating surface of the guide element 3 and the steel rail adopts a profiling design, which maintains close contact with the rail waist surface of the entire steel rail. In addition, in order to prevent wear of the contact surface of the guide element 3 and the guide brackets 2 and 2a, a surface connecting plate 11 made of steel plate is provided on the contact s...
Example Embodiment
[0085] Example three
[0086] Such as Figure 5 , Image 6 The difference between the elastic fixing device for the track of the present invention and the second embodiment is that the guide element 3 is made of an elastic polymer material, and in this example, a rubber material is used. A reinforcement element 12 is also provided in the guide element 3, and the reinforcement element 12 is composed of three layers of wire meshes arranged in the guide element 3. The guide element 3 is provided with grooves on the contact surface with the rail waist, which is beneficial to adjust the horizontal elasticity and vertical elasticity of the guide element 3, and helps to dissipate heat. During the working process, the rail 9 and the guide brackets 2 and 2a are guided by The elastic deformation of the element 3 can move relatively, and the guide element 3 does not have to slide with the guide bracket. Therefore, positioning holes are provided on the surface connecting plate 11, and the co...
