Rail Quick Change System

Abstract

The invention relates to the technical field of fire protection rescue cars, in particular to a fast conversion system for rails. The fast conversion system comprises a frame and road driving bridges connected to the frame. Rail driving systems are arranged at the two ends of the frame and comprise upper rotating bases, lower rotating bases and swing arms. The upper rotating bases are fixedly connected with the frame, the lower rotating bases are connected with the upper rotating bases in a rotating mode, and one ends of the swing arms are hinged to lower supporting legs of the lower rotating bases. According to the fast conversion system, a wheel set has the rotation characteristic, compared with the condition that steering is achieved through a rail extrusion wheel set and braking is achieved through reverse braking of a driving system in the prior art, the braking mode is not limited by the speed limit of 40Km / h, the speed is higher than a common rail vehicle speed by more than one time, and the requirement of urgency and fastness in the fire protection rescue process can be met.

Description

technical field [0001] The invention relates to the technical field of firefighting and rescue vehicles, in particular to a rapid rail switching system. Background technique [0002] When there is a dangerous situation in the railway tunnel and the subway, the main fire rescue method is to use the fire hydrant and other devices installed inside it to put out the fire, and the subway can also enter on foot from the nearest subway exit. These fire-fighting steps cannot meet the needs of quick and timely response, and will also bring hidden dangers to rapid evacuation when the fire is out of control. Moreover, most of the existing fire engines must be operated under the vehicle. In the environment filled with dense smoke and toxic gases, the life safety of firefighters cannot be guaranteed.

These fire-fighting steps cannot meet the needs of quick and timely response, and will also bring hidden dangers to rapid evacuation when the fire is out of control

Moreover, most of the existing fire engines must be operated under the vehicle. In the environment filled with dense smoke and toxic gases, the life safety of firefighters cannot be guaranteed.

[0003] 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
