Description

Technical Field

[0001] The utility model relates to the field of railway infrastructure equipment, in particular to a ballast retaining wall which is convenient for maintenance and is used in railway construction. Background Art

[0002] The ballast retaining wall is an important component of the high-speed railway bridge deck structure. It is mainly used to prevent the vibration, displacement and resonance of the ballast, and the movement of the bridge caused by the expansion and contraction of the rails. The materials used to make the ballast retaining wall mold are usually steel plates and plastics. It is located on both sides of the high-speed railway. It not only has a protective function to ensure the stability and safety of the high-speed railway operation, but also presents an aesthetic effect in appearance. With the rapid development of the railway industry, in recent years, various railway departments have put forward rectification requirements to improve the walking conditions of station staff on the outside of the track, requiring the laying of welfare ballast on both sides of the track and between the tracks, and laying of panels for working personnel to walk on it, and ensuring the safety of personnel passage.

[0003] In railway construction, traditional ballast retaining wall designs often adopt integral casting or fixed connection methods, which not only increases the construction difficulty, but also often requires large-scale disassembly and repair in the subsequent maintenance process once problems arise, greatly affecting construction efficiency and maintenance costs. To this end, we propose a ballast retaining wall based on railway construction that is easy to maintain. Utility Model Content

[0030] Furthermore, the disassembly and assembly device 19 includes a pry plate 8 and a partition plate 11. The partition plate 11 is fixedly connected to the inner cavity of the disassembly groove 9. The partition plate 11 divides the disassembly groove 9 into two parts. Both sides of the partition plate 11 are provided with holes that are the same size and parallel to the installation socket 7. Two pry plates 8 symmetrical about the partition plate 11 are fixed to the outer end of the inner wall of the disassembly groove 9.

[0031] Furthermore, the fixing device 20 includes a fixed rod 13, a sliding mounting block 14, a limiting column 17 and a spring 18. Two fixed rods 13 are movably inserted in the two mounting holes 7 corresponding to the inner walls on both sides of the mounting cavity 12.

[0034] Working principle: This device adopts modular design. Each module of the ballast retaining wall in this device is made of high-strength and weather-resistant materials, ensuring its good structural performance and durability. When it is necessary to install this device, first arrange multiple ballast retaining walls neatly according to the design requirements, fix the ballast retaining wall at one end, open the protective door 10 in the baffle 2 of the next ballast retaining wall, and then insert the straight plate tool into the disassembly slot 9 between the right pry plate 8 and the partition plate 11, and fix the two fixed rods 1. 3 is pried and squeezed, and one end of the fixed plug rod 13 is squeezed and opened to move horizontally toward the other end. When the fixed plug rod 13 moves horizontally toward the other end, the spring 16 is squeezed through the limiting ring 15, so that the spring 16 is deformed and the squeezing force is transmitted to the sliding mounting block 14, so that the bottom of the sliding mounting block 14 squeezes the limiting column 17. Since the top of the limiting column 17 is a smooth hemispherical surface, when the limiting column 17 is squeezed in the horizontal direction, the force is converted into When the top of the limit column 17 moves to the position where the lower surface of the sliding mounting block 14 is horizontal, the elastic deformation of the spring 16 drives the sliding mounting block 14 to move rapidly in the direction of the operator's squeezing, and finally makes the other side inclined surface of the bottom surface of the sliding mounting block 14 tangent to the top of the limit column 17 again. However, through the lever principle, the operator can complete the installation prying operation by one person; the two fixed insertion rods 13 after moving are inserted into the installation socket 7 on the left side of the next ballast retaining wall, and the installation is completed; during use, the arc groove 13, the arc groove 24 and the drainage top groove 6 can quickly drain rainwater falling on the surface of the ballast retaining wall, reducing the erosion of the device body. At the same time, the arc design can reduce the noise and vibration generated by the high-speed rail during high-speed movement, reducing the impact on the environment.
