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...

Embodiment Construction

[0017] In the following, the embodiment of the pouring and foaming vehicle of the present invention will be described by taking polyurethane pouring for ballast bed as an example. However, those skilled in the art should understand that the pouring and foaming vehicle according to the present invention can be applied to a variety of occasions where the pouring point needs to be poured, and these descriptions are only used to explain the principle of the present invention by way of example, and are not intended to explain the principles of the present invention. Limitations on the protection scope and application scope of the invention.

[0018] figure 1 is a side view of a pouring and foaming vehicle 100 according to an embodiment of the present invention, image 3 It is a front view with some parts omitted.

[0019] Such as image 3 As shown, the sleeper 180 is laid on the ballast bed 270 , and the steel rail 170 is supported on the sleeper 180 . The track bed 270, the sl...
