A control system for unloading a whole group of coal hopper cars

Abstract

The invention belongs to the technical field of a railway lorry pneumatic control system, and particularly relates to a coal hopper car whole group unloading control system. An air storage cylinder communicates with an exhaust plug door I through an air storage cylinder branch pipe; the exhaust plug door I communicates with an action valve; the action valve communicates with a check value; the check valve communicates with a three-way joint; the three-way joint is respectively connected with an exhaust plug door II through a control pipe and a main air inlet pipe through an air inlet branch pipe; the exhaust plug door II communicates with the action valve; a combined cut-off plug door is arranged between the air inlet branch pipe and the main air inlet pipe; the main air inlet pipe communicates with a left rotating folding angle plug door; the left rotating folding angle plug door communicates with an air source. The coal hopper car whole group unloading control system has the advantages that the requirement of bottom door opening and closing of whole car marshalling unloading of the coal hopper car is met; the car unloading efficiency is improved; the operation personnel are reduced; meanwhile, the injury on personnel due to unloading dust can be avoided.

Description

technical field [0001] The invention belongs to the technical field of pneumatic control systems for railway wagons, in particular to a control system for unloading a whole group of coal hopper wagons. Background technique [0002] The existing coal hopper car unloading methods mainly include single wind, manual unloading or ground touch unloading. Among them, the pneumatic unloading method cannot realize the simultaneous unloading of multiple connected vehicles because the wind source pressure comes from the brake supervisor, and there is no signal transmission for connecting multiple vehicles. The touch-type unloading structure mainly relies on the contact between the ground mechanism and the upper transmission handle of the vehicle, and the bottom door can only be opened under the action of the moving force of the vehicle, so it cannot realize the requirement of unloading the entire column at the same time. According to the influence of the operating conditions of railwa...
