Abstract

The invention discloses drying-free multi-gun head double-channel pouring equipment for polyurethane ballast bed curing. The drying-free multi-gun head double-channel pouring equipment comprises a container and a pouring truck, and the container internally comprises: a C component mixing tank, a temperature control unit used for controlling the internal temperature of the container and a tractiondevice used for pulling the pouring truck; the pouring truck internally includes a component A metering and conveying device, a component B metering and conveying device and a component C metering andconveying device, and further comprises N mixing heads, the output ends of the mixing heads are connected to a flow divider, and each mixing head is connected to the component A metering and conveying device, the component B metering and conveying device and the component C metering and conveying device. The invention aims to provide the drying-free multi-gun head double-channel pouring equipmentfor polyurethane ballast bed curing. The problems that in the prior art, cast-in-place foaming operation of a polyurethane ballast bed block is greatly influenced by weather and the environment, operation cannot be conducted in a humid environment, and pre-drying is needed are solved, and the purposes that the material C is added to lower the requirement for the operation environment and improvethe operation efficiency are achieved.

Description

technical field [0001] The invention relates to the field of polyurethane ballast beds, in particular to non-drying multi-gun-head double-channel pouring equipment for polyurethane ballast bed curing. Background technique [0002] The track bed is an important part of the track and the foundation of the track frame. Including sleepers and ballast stones, the main function is to support the sleepers, evenly transmit the huge pressure on the upper part of the sleepers to the roadbed surface, and fix the position of the sleepers, prevent the longitudinal or lateral movement of the sleepers, greatly reduce the deformation of the roadbed, and ease the wheel load of rolling stock. Impact on rails for easy drainage. [0003] The traditional ballast bed is divided into ordinary ballast bed, asphalt track bed and concrete monolithic track bed. Ordinary ballast bed is usually piled up by hard crushed stones with a certain particle size, gradation and strength, and graded pebbles or ...
