Description
Technical Field
[0001] This invention relates to the field of subway track construction technology, and more specifically to a multi-functional subway track construction vehicle. Background Technology
[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. Trains run on fully enclosed tracks. Lines in the city center are primarily located in underground tunnels, while lines outside the city center are generally located on elevated bridges or at ground level. Before a subway can be put into operation, tracks must be laid, which requires the use of construction vehicles. However, subway track construction is often time-consuming. After processing, the tracks are prone to rusting over long periods of storage. Specialized grinding tools are needed for alignment and polishing. However, conventional subway track construction vehicles often only have the function of transporting tracks. Therefore, after the tracks are fixed, they are often manually polished one by one to ensure the flatness of the track surface. This method is not only inefficient but also greatly increases the workload of personnel, thus increasing costs. Therefore, designing a multi-functional subway track construction vehicle to solve these problems is particularly important. Summary of the Invention
[0003] To address the aforementioned problems, this invention designs a multifunctional subway track construction vehicle. Through a grinding mechanism, the subway track can be ground and rust-removed before laying, and then the track can be laid and fixed. This not only greatly reduces the workload of personnel and lowers costs, but also significantly improves work efficiency and enhances practicality.
