Ballast discharging flow control device for ballast hopper car

Abstract

The invention discloses a ballast discharging flow control device for a ballast hopper car. The ballast discharging flow control device for the ballast hopper car comprises a check block, a check block installation base, a transmission shaft and a control lever, wherein the check block is connected with the check block installation base in a rotary mode through a round fixing pin, a check block adjustment hole is formed in the check block, multiple adjustment through holes which correspond to the check block adjustment hole are formed in the check block installation base, when the check block rotates to the position of the check block adjustment hole and corresponds to one adjustment through hole in the check block installation base, the check block is positioned through a bolt assembly, the control lever is fixedly connected with the transmission shaft, the transmission shaft is connected with a ballast discharging bottom door of the ballast hopper car, the transmission shaft rotates until the control lever is in contact with the check block, and gear shifting is stopped at the moment. According to the ballast discharging flow control device for the ballast hopper car, the opening degree of the ballast discharging bottom door is adjusted by controlling the rotation angle of the transmission shaft, multi-gear ballast discharging flow control can be effectively achieved, the work efficiency of the ballast hopper car is improved, and serious waste of redundant ballast is avoided; in addition, ballast discharging flow gears can be selected, and operation safety during ballast discharging through a middle door is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of railway transportation tools, and in particular relates to a ballast unloading flow control device for a ballast hopper car. Background technique [0002] At present, in the process of railway construction, ballast hopper cars are usually used to discharge ballast to the inner and outer sides of the track. The actual lack of ballast during the use of the railway track bed is different, and the required ballast discharge volume is different. The existing ballast hopper truck cannot realize ballast discharge flow control during pneumatic unloading, which is not conducive to the precise operation of line maintenance and ballast replacement, resulting in a large amount of waste of ballast. [0003] And the existing stone ballast hopper car can't install the manual unloading device to the inner side of the track to unload, and can only adopt the pneumatic operation mode to unload. The existing pneumatic opera...

AI Technical Summary

Problems solved by technology

Ballast discharge flow control cannot be realized when the existing stone ballast hopper truck is unloaded by wind, which is not conducive to the precise operation of line maintenance and ballast replacement, resulting in a large waste of stone ballast

[0003] Moreover, the existing ballast hopper car cannot be equipped with a manual unloading device for unloading to the inner side of the track, and can only be unloaded by pneumatic operation.

The existing pneumatic operation cannot control the flow of unloading ballast, and the pneumatic operation is extremely fast, and it is easy to form a pile of ballast in the middle of the track, causing the vehicle to derail

Based on safety considerations, some railway bureaus expressly stipulate that ballast hopper cars cannot use the middle door to unload ballast. During the process, the stone ballast unloaded on both sides can only be transported to the middle of the railway by manual operation, so the efficiency is low
