Problems solved by technology

The current track starting technology of large-scale road maintenance machinery uses 15.7m steel strings for track starting and 21m steel strings for track tracking. Due to the limitation of the length of the equipment, the design of the equipment itself using steel strings cannot eliminate long-wave irregularities above 20m vertical

Abstract

The invention discloses a ballast track laser intelligent track lifting and lining system. The ballast track laser intelligent track lifting and lining system comprises a track lifting and lining tamper (1) and is characterized by further comprising an integrated full-route measurement device, the full-route measurement device comprises a laser transmitting device (4) and an image receiving device (5), the image receiving device (5) is arranged on a front end image receiving trolley (7), and the laser transmitting device (4) is arranged on a laser transmitting movable trolley (2) in a distance. The image receiving device (5) is provided with a two-dimensional automatic tracking mechanism. A construction method includes the steps that route geometrical shape parameters are input, and track lifting and lining are conducted; each time the ballast track laser intelligent track lifting and lining system advances by a set distance, an electrical control system collects front end lifting and lining quantity data, a gva system outputs track lifting and lining quantity data control operation of an operation position, and the gva system feeds back track lifting and lining quantity data of an operation process. By means of the ballast track laser intelligent track lifting and lining system and the construction method, ballast track accurate track lifting and lining measurement workloads are greatly reduced, construction accuracy is improved, the advantages of the full-route measurement system and a large track maintenance machine are given into full play, and the problem of man-made errors occurring in the connection between the measurement procedure and the track lifting and lining construction procedure is thoroughly solved.

Description

technical field [0001] The invention relates to the field of ballasted track construction, in particular to a ballasted track laser intelligent track removal system, which is a construction system and method for precise arrangement of large-scale road maintenance machinery track beds on ballasted tracks, and is a key technology for speeding up ballasted track passenger dedicated lines. technical background [0002] Due to the advantages of low cost, short construction period, and strong adaptability, ballasted track has developed a large-scale 250km / h passenger dedicated line with ballasted track in my country in recent years. higher requirement. Track irregularities can be divided into long-wave irregularities and short-wave irregularities according to wavelength. Long-wave irregularities mainly affect the comfort of passengers. Short-wave irregularities can be absorbed by the vibration reduction system in vehicle design. [0003] The research data shows that when the train...
