Embodiment Construction

[0010] Such as figure 1 As shown, the air cylinder push rod 1 is an actuator that controls the opening and closing of the bottom door. When the door needs to be opened or closed, the ground power supply device 4 supplies power to the electronic control unit 5, so that the electronic control unit 5 drives the three-position five-way solenoid valve 3 Complete the corresponding operation, and then complete the opening or closing of the bottom door. Air source 6 supplies air (pressure air) for the whole system. The air source 6 communicates with the air storage cylinder 7. When the funnel car passes the ground power supply device 4, according to the direction of the ground power supply when it is powered on, the electronic control unit 5 will judge whether it is an instruction to open or close the door at this time, and then drive the three-position five-way electromagnetic The coil corresponding to the valve 3 is energized, and the air path between one of the working chambers in...

Abstract

The invention relates to a drive control system for a bottom door opening and closing mechanism of a self loading hopper car. The system comprises a ground power source device, a three-position five-way electromagnetic valve and an electronic control unit. The system is characterized in that the core component of the electronic control unit is a single chip machine, the three-position five-way electromagnetic valve is connected between an air storage cylinder and a two-way air cylinder in series and is controlled by the electronic control unit, the single chip machine is used for collecting a voltage signal input to the electronic control unit to judge whether the voltage signal is a door opening signal or a door closing signal, and at the same time a door opening or a door closing command is sent to a solid-state relay. After the solid-state relay is driven, an air vent corresponding to the three-position five-way electromagnetic valve is conducted to charge the air to a working chamber corresponding to the two-way air cylinder, so that the opening or the closing of the bottom door is realized. The system has the advantages that the opening or the closing of the car door can be completed within short time in an electronic operation way, and the operation is convenient and easy; the operation of the bottom door can be controlled according to a power-on direction, so that the safety is high; at the same time, the set parameters can be changed according to the use requirements and the structural features, so that the degree of the generalization is high.

Description

technical field [0001] The invention relates to a drive control system for an opening and closing mechanism of a bottom door of a self-unloading hopper car, belonging to the technical field of control devices for a bottom door of a railway coal hopper car. Background technique [0002] At present, the driving control of the door opening and closing mechanism of the coal hopper car in my country is through the collision of ground machinery or artificially controlling the pneumatic system to make the two-way air cylinder move and then drive the mechanical structure to open and close the door. Both have problems such as wear and tear of the mechanism and low efficiency, and human-controlled air movement also has operational safety issues. Therefore, improving the unloading efficiency of railway coal hopper cars, speeding up the turnover of coal, and improving vehicle reliability and operational safety have become railway vehicles. The primary research topic for truck manufactur...
