Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rail transit facilities, in particular to a trackbed slotting vehicle for laying optical cables. Background Art
[0002] With the development of sensor technology, more and more advanced and accurate monitoring technologies have been introduced into the rail transit industry, such as grating optical cable distributed monitoring technology. The key step to implement this technology is to continuously bury the optical cable in the roadbed along the longitudinal direction of the subway line, which requires grooving on the roadbed surface. How to accurately and efficiently complete the grooving is the most basic, critical and time-consuming process in the entire optical cable laying project. However, the operating line only has 2 or 3 hours of skylight time at night for construction every day, which greatly restricts the progress of the project. In addition to using a grooving machine, the grooving process also requires continuous water spraying to cool the saw blade, and simultaneous dust collection to prevent pollution of the track line. In addition, in existing rail transit lines, various functional facilities are arranged on the roadbed, and their power lines and data lines cross the roadbed surface. When grooving, such pipelines and facilities need to be avoided and crossed to prevent damage. In addition, due to design requirements, the roadbed styles in rail transit vary greatly, such as ordinary roadbeds with double-sided ditches, ordinary roadbeds with central ditches, trapezoidal sleepers, steel spring floating plates, etc., and the grooving path changes frequently due to changes in the roadbed form. Therefore, track bed grooving equipment that can integrate grooving, cooling and dust collection needs to be developed urgently.
[0003] At present, the grooves on the roadbed are usually cut manually, which has high labor costs and low efficiency. In addition, manual cutting depends entirely on the experience and skills of the construction personnel, which can easily lead to uneven cutting, affecting the subsequent embedding of optical cables and not looking good.
