Abstract

The invention provides a pneumatic cabinet comprising a wind source cabinet and a pneumatic plate. The wind source cabinet comprises a wind source frame. A main wind cylinder is arranged below the wind source frame, and an auxiliary wind cylinder, a main compressor, a main dryer and a reverse flow check valve are arranged above the wind source frame. A filter is arranged on the lateral side of the wind source frame. The pneumatic plate is arranged above the lateral side of the wind source frame, and is integrally provided with a bow rising module, pressure switches, a sanding module and an auxiliary air supply device. The pneumatic plate highly integrally designed can save space and make the whole pneumatic cabinet attractive and tidy. Due to the fact that the compressors, the dryers and the main wind cylinder are mounted on the wind source frame while the pneumatic plate on the wind source cabinet, the center of gravity of the whole pneumatic cabinet shifts downwardly to be well integrated with a locomotive, and damage brought by shockwaves during operation of the locomotive can be reduced.

Description

technical field [0001] The invention relates to locomotive manufacturing technology, in particular to a pneumatic cabinet used on the locomotive. Background technique [0002] The pneumatic cabinet is widely used in electric locomotives. It integrates the main core components and main control components of the air source system, and is an essential component of the locomotive braking system. The pneumatic cabinet can effectively ensure the cleanness and dryness of the air source used by the locomotive, the quality is qualified and the air pressure is stable. It is closely related to the development of locomotives. [0003] Due to the complexity of the locomotive brake system, the pneumatic cabinet must integrate various functional components such as machinery, pipelines, and electricity. Common pneumatic cabinets are integrated in one cabinet or divided into two cabinets, and are mostly placed upright in the car body, occupying a large space, and damage caused by vibration...
