Abstract

The invention discloses a double-block type sleeper circumferential concrete vibration supplementing device, solving the problem that no double-block type sleeper circumferential concrete vibration supplementing device exists at present. A lifting cylinder and guide sleeves are fixed on a base, a guide column is arranged in each guide sleeve, connecting frames are fixed on the lifting cylinder andthe upper end of the guide column, a rack is arranged on the surface of the guide column, and a gear shaft is fixed between the guide sleeves; connecting boards are fixed at two sides of the connecting frame, and a rectangular orifice is arranged on the surface of the connecting frame; lifting connecting bars are arranged in the rectangular orifice, the upper part and the lower part of the connecting board and the lifting connecting bar are both provided with hinge holes and grooves, and hinge bars are crossways arranged between the hinge holes and the grooves; an open-closed cylinder is fixed between the lifting connecting bars, a U-shaped vibro baseboard is fixed on the bottom end of the lifting connecting bar, the baseboard is hinged with a connecting bar, and hollow screws are fixed on the bottom of the baseboard; the other end of the connecting bar is hinged with a bracket, and a variable frequency vibrator is fixed on the bracket. The invention improves compactness and impermeability of concrete, and has quick and convenient operation.

Description

technical field [0001] The invention relates to auxiliary tooling for construction of a double-block ballastless track, in particular to a device for vibrating the concrete of the track bed slab around a double-block sleeper, in particular to a concrete vibrator around a double-block sleeper. Background technique [0002] The Wuhan-Guangzhou Passenger Dedicated Line is my country's first high-speed railway with a design speed of 350Km / h. The design adopts the German Rheda2000 double-block ballastless track technology. The core of this technology is: using the tool rail to fix the prefabricated double-block sleeper; using the three-dimensional control measurement technology to accurately position the tool rail; the concrete of the cast-in-place track bed slab permanently fixes the double-block sleeper in the track bed slab; The long rails form a seamless line. [0003] The double-block sleeper adopts steel mold prefabrication, steam curing process, and uses a release agent t...
