Description

Technical Field

[0001] The utility model relates to the field of trams, in particular to a sand injection device for a sand spreading system of a tram. Background Art

[0002] Public transportation is prioritized, which is fully reflected and fully utilized in the transportation system. The two-way tram roads in the middle of the road are dedicated channels for trams, which have priority at all times. Cars can only drive in a single lane beside the road. This tram restaurant tourism project is operated in the normal tram system. The boarding location is the usual tram boarding and alighting station. Many tram stations have vehicle arrival visual screens. Therefore, in addition to a full-time driver, each tram also has a switchman accompanying the vehicle. The tram also keeps in touch with the dispatching center to deal with emergencies at random. The scenery along the way is beautiful and delicious.

[0003] However, the sand injection device of the currently used tram sand spreading system is an integral structure, and its position cannot be adjusted during use. When the sand injection position needs to be changed, manual operation is required to re-fix it, which wastes time and labor and is extremely inconvenient to use.

[0004] In view of this, research and improvement are carried out on the existing problems, and a sand injection device for a tram sand spreading system is provided. The device has a reasonable structural design and can automatically align the sand injection port when in use. When the sand injection position needs to be changed, the roller can move horizontally on the track to automatically change the sand injection position. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content
