Compressed air control and distribution device for return and rescue of motor train units

Abstract

A compressed air control and distribution device for return and rescue of motor train units is characterized by comprising a hoisting frame, a BP rescue conversion device, two air storage cylinders, a valve plate and a hanging plate, wherein a hoisting hole for hoisting the whole device is formed in the hoisting frame, a plurality of installing holes are formed in the hoisting plate according to the positions of the valve plate, air storage cylinder installing hoisting belts and the hoisting plate to facilitate fastening and installation conducted on the valve plate, the air storage cylinders and the hanging plate through bolts, the BP rescue conversion device is installed on the hoisting frame and used for achieving the function of converting electric signals and air way signals during return and rescue. A complicated return and rescue control device is integrated through integrated design concept under the condition that a vehicle body chassis zone space is limited, mutual return and rescue of different types of motor train units are achieved functionally, and convenience is brought to running organization. In addition, the compressed air control and distribution device is simple to install and fix and convenient to maintain and test, and occupied space is greatly decreased.

Description

technical field [0001] The invention belongs to the electric control and distribution technology of rail transit, and in particular relates to a compressed air control and distribution module for return and rescue of EMUs. Background technique [0002] Due to different design platforms and design ideas, there are two different air brake control methods for EMUs in my country: one is the air brake control method with single-pipe design, that is, the air brake is controlled by a single main air pipe. One is the air brake control mode with double-pipe design, that is, the straight-through electronic air brake control mode is realized through the main air duct, and the indirect air brake is realized through the train tube. control method. [0003] To meet the needs of locomotive rescue return, EMUs with single-pipe air brake control mode need to be connected with a brake command converter (rescue return panel) when the locomotive is returned to convert the train tube decompressio...

AI Technical Summary

Problems solved by technology

The electrical and air circuit control parts of the loopback rescue device are designed separately, or the rescue device and the loopback device are two sets of independent equipment. The electrical and structural interfaces of the loopback rescue device of different EMUs are very different, and they cannot be interchanged and cannot meet the needs of the future. The need for standardized design of EMUs
