Abstract

The present invention discloses a pouring and foaming vehicle comprising a movable vehicle body, at least one pouring and foaming unit, a height adjusting device enabling a mixing head to move in a height direction and a control device for controlling the height adjusting device to enable the mixing head to move in the height direction to a predetermined position and controlling the at least one pouring and foaming unit to pour. The pouring and foaming unit comprises at least one raw material tank storing at least one raw material and a pouring head configured to receive the at least one raw material from said at least one raw material tank and perform pouring. The pouring and foaming vehicle according to the present invention may travel along an object to be poured and perform the pouring quickly and efficiently and save human power and time.

Description

technical field [0001] The invention relates to pouring and foaming equipment, in particular to pouring and foaming equipment for preparing polyurethane ballast beds. Background technique [0002] Railway track bed usually refers to the ballast layer laid under the sleeper and above the roadbed. It is the foundation of the track frame and its main function is to support the sleeper and evenly distribute the huge railway vehicle load from the rail and the sleeper to the bed of the roadbed. , reduce roadbed deformation, and ensure driving safety. [0003] In recent years, with the rapid growth of people's trips and cargo transportation, the ballast bed bears the huge load transferred to it by high-speed and heavy-duty trains through rails and sleepers. Under the action of huge loads, the ballast stones that make up the ballast bed are more likely to collide, shift, and break and sand as time goes by, resulting in deformation and functional degradation of the ballast bed. The...
