Abstract

The invention discloses a ballastless turnout point switch preformed groove size control device. The device comprises a track bed slab, a preformed groove template, turnout sleepers and steel rails, the turnout sleepers are arranged on the track bed slab, the steel rails are arranged on the turnout sleepers, the preformed groove template is arranged between the two turnout sleepers, the preformedgroove template is arranged in a through groove in the track bed slab, the preformed groove template comprises four sections, and the four sections of the preformed groove template are symmetrically distributed on the two sides of the track bed slab. The preformed groove formwork comprises two side plates and a bottom face plate, the two side plates are arranged on the turnout sleepers respectively, the bottoms of the side plates are bent to form bottom folded corners, and the two sides of the bottom face plate are movably connected with the bottom folded corners on the two side plates respectively. The invention further discloses a method for controlling the size of the preformed groove through the device, the vertical lead screws are fixed to the M16 nuts at the two ends of the bottom panel, the distance between the bottom panel and the bottom of the steel rail is adjusted through the vertical lead screws, and the direction of the drainage slope is adjusted through the vertical leadscrews. Not only are manpower and material resources saved, but also detection quality and detection efficiency are improved.

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...
