Cutting device for isolation layer on ballastless track base

Abstract

The invention specifically discloses a device for cutting the isolated layer on a ballastless track pedestal, and solves the problem that existing geotechnical cloth at a pedestal groove part is cut manually, thus being easy to misplace, disaccord in size, serious in waste and low in efficiency. The device comprises a steel angle frame, wherein reinforcing steel angles are fixed at the outer wall of the vertical flanges at four corners of the steel angle frame, a hand shank is fixed on each reinforcing steel angle, a rubber blanket is fixed on the bottom surface of the horizontal flange of the steel angle frame, and positioning needles are fixed on the bottom surface of the horizontal flange of the steel angle frame, a track wheel is arranged on the horizontal flange of the steel angle frame in a sliding manner, a guide wheel is sleeved with the track wheel and fixed with the same, width of the track wheel on two sides of the guide wheel is the same as that of the horizontal flange of the steel angle frame, a rotating shaft is fixed at the axes of the guide wheel, two ends of the rotating shaft are arranged on the bracket, a rope and cloth hot cutting knife is connected to the bracket, and the cutting bit of the rope and cloth hot cutting knife is in the same vertical plane with the guide wheel. According to the device for cutting the isolated layer on the ballastless track pedestal, work efficiency is effectively improved, and cutting accuracy is greatly improved.

Description

technical field [0001] The invention relates to a construction tool for a ballastless track of a high-speed railway, in particular to a cutting device for an isolation layer on a ballastless track base. Background technique [0002] The foundation of the ballastless track is called the base. In order to ensure that the track in the bridge section can move slightly with the thermal expansion and contraction of the beam body, and to facilitate quick plate replacement and maintenance after operation, a layer of isolation layer (without geotextile) to prevent the upper cast-in-place concrete from "sticking" to the base. [0003] In the bridge area, the base is a reinforced concrete structure divided into sections according to the length of the track slab, and the isolation layer should also be cut and laid in sections; at the same time, in order to prevent the large displacement of the track structure and the base from affecting the smoothness of the line, generally set up on th...
