Abstract

The invention discloses a ballastless turnout switch machine reserved groove size control device, which comprises a ballast bed plate, a reserved groove template, a switch sleeper and a steel rail. The formwork is arranged between the two fork sleepers, and the formwork for the reserved groove is set in the through groove of the ballast bed slab. The formwork for the reserved groove includes four segments, and the four sections of the formwork for the reserved groove are symmetrically distributed on both sides of the ballast bed slab. The reserved groove formwork includes side panels and bottom panels. There are two side panels. on the bottom chamfer articulation. The invention also discloses a method for using the device to control the size of the reserved slot. Fix the vertical screw on the M16 nuts at both ends of the bottom panel, use the vertical screw to adjust the distance from the bottom panel to the bottom of the rail and use the vertical screw to Adjust the direction of the drainage slope. It not only saves manpower and material resources, but also improves the detection quality and detection efficiency.

Description

technical field [0001] The invention relates to the technical field of construction of a ballastless turnout switch machine, in particular to a device and method for controlling the size of a reserved groove of a ballastless turnout switch machine. Background technique [0002] The precise control of the size of the reserved groove of the switch machine is one of the important links in the precise installation of the track base components in the track laying construction. In a track laying project of a high-speed railway main line, the ballastless turnout with long sleepers buried is used. The ballastless The bottom of the turnout sleeper is a truss structure, the switch part is arranged between multiple switch sleepers, the power conversion rod and the external locking device are installed between the two concrete switch sleepers, and the switch is installed at the end of the switch sleeper. , The groove width of the reserved groove of the tie rod of the switch machine is c...
