Problems solved by technology

In the field of fire trucks in the world, there are only similar fire trucks produced by AMP in Austria, but these fire trucks only use MAN two-way driving chassis, without track driving function, and the cab, control, and upper equipment are no different from ordinary fire trucks

Abstract

The invention relates to the field of rescuing fire fighting trucks, in particular to a bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck. The bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck comprises a truck frame and road traveling bridges connected to the truck frame, and further comprises rail traveling systems, each rail traveling system comprises an upper rotation base, a lower rotation base and a swinging arm, the upper rotation bases are fixedly connected with the truck frame, the lower rotation bases are connected with the upper rotation bases in a rotatable mode, and one ends of the swinging arms are hinged to lower landing legs of the lower rotation bases. According to the bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck, wheel pairs have the rotation characteristic, compared with the conditions that in the prior art wheel pairs are pressed through a rail to carry out steering, and reverse braking is achieved through a driving system, a braking mode of the bidirectional-traveling road-rail dual-purpose multifunctional emergency rescuing fire fighting truck is not limited by the 40-Km / h truck speed any more, the speed is one time higher than that of a conventional road-rail truck, and the emergent and rapid requirements during fire rescuing can be met.

Description

technical field [0001] The invention relates to the technical field of emergency rescue fire trucks, in particular to a dual-purpose emergency rescue fire truck with two-way driving rails. Background technique [0002] Existing rail dual-purpose fire trucks use a simple way of lifting wheels to switch between rails. The structure itself has no turning characteristics, which makes it difficult for the wheels to align with the rails when the vehicle is on the rail. The track time is very long, and with the use of this structure, when driving on the vehicle track, the turning is to rely on the rail to squeeze the wheel to turn, and the braking is to rely on the reverse braking of the drive system. In this way, the speed of the vehicle can only be controlled at 40Km / h. Urgent and fast requests cannot be met. [0003] In order to solve the actual fire rescue and rescue problems. It is necessary to develop a two-way rail dual-purpose multifunctional emergency rescue fire truck ...
