Problems solved by technology

During work, it is necessary to manually operate the control valve to control the conversion of the air passage, open and close the bottom door, and there is a high risk of misoperation
In addition, the hopper truck needs to be in a static state during the unloading process, and the on-board gas storage device needs to be inflated first, and the cargo can only be unloaded after reaching the specified air pressure. Only one vehicle can be unloaded at a time, which is inefficient
[0004] The manual control system is a manually operated handwheel control lever mechanism, and the hopper car also needs to be in a static state during the unloading process, which is more time-consuming and laborious

Embodiment 1

[0039] figure 1 It is a structural schematic diagram of an on-board system of an exemplary railway hopper car opening and closing control system of the present invention. like figure 1 As shown, the vehicle-mounted system of this embodiment includes a capacitor 1 as an energy storage device, a controller 2, a first push rod 3, a second push rod 6, a charging contact 5, a discharging contact 4 and a connection line. The capacitor 1 and the controller 2 are electrically connected through a connection line. The capacitor 1 is also electrically connected to the charging contact 5 and the discharging contact 4 through connection lines, respectively. The controller 2 is further electrically connected with the first push rod 3 and the second push rod 6 through the connecting line.

[0040] figure 2 It is a schematic diagram of the ground device and the operation process of the hopper car of an exemplary railway hopper car opening and closing control system of the present inventi...

Embodiment 2

[0045] Except that the first detector 8 and the second detector 9 are combined into the same detector having the information that the hopper car enters the first position and the second position, the railway hopper car opening and closing control system of the present embodiment is the same as the embodiment 1 is the same.

Embodiment 3

[0047] The opening and closing control system of the railway hopper car in this embodiment includes n sets of on-board systems and one set of ground devices. where n is the number of hopper cars in a train of railway hopper cars, n≥1. Each in-vehicle system is the same as the in-vehicle system in Embodiment 1. The ground unit is the same as that in Embodiment 1.

Abstract

The invention discloses a railway hopper car opening and closing control system and control method. The opening and closing control system comprises a train-mounted system used for being installed ona railway hopper car and a ground device used for being installed on a loading and unloading freight yard. Through cooperation of the train-mounted system and the ground device, when a train passes through the loading and unloading freight yard at a low speed, a top cover and / or a bottom door of the hopper car can be automatically opened and closed, the train continuously conducts freight loadingand unloading operation ceaselessly, and therefore the loading and unloading operation efficiency is improved.

Description

technical field [0001] The present invention relates to an opening and closing control system and method, in particular to a railway hopper car opening and closing control system and method suitable for automatic opening and closing of a railway hopper car top cover and / or bottom door device. Background technique [0002] At present, most of the bottom door opening and closing systems of domestic railway hopper cars adopt the form of wind and manual control. The pneumatic opening and closing system uses the compressed air provided by the locomotive air source as the power, and controls the lever mechanism connected to it through the control pipeline, control valve, two-way cylinder, etc., and then realizes the opening and closing of the bottom door of the railway hopper car. The manual control system controls the opening and closing of the bottom door through a hand wheel, a reducer and a lever mechanism. [0003] Due to the use of compressed air as power in the pneumatic s...
