Unloading-leveling integrated stone ballast hopper vehicle

Abstract

The invention discloses an unloading-leveling integrated stone ballast hopper vehicle which comprises a vehicle body, a stone ballast unloading device, a braking device, a coupler buffer device and a steering frame. The stone ballast unloading device comprises a stone ballast unloading bottom door, a mechanical transmission device, a wind-control stone ballast unloading device and a manual stone ballast unloading device. A stone ballast leveling device is arranged on the vehicle body. The stone ballast leveling device comprises stone ballast leveling plate formation and a stone ballast leveling plate lifting driving mechanism. The stone ballast leveling plate formation moves to a steel rail when the stone ballast leveling plate formation descends through the stone ballast leveling plate lifting driving mechanism, and at the moment, the lower end face of the stone ballast leveling plate formation is flush with or is lower than the upper end face of the steel rail. The stone ballast leveling plate formation forms a self-locking state when the stone ballast leveling plate formation ascends through the stone ballast leveling plate lifting driving mechanism, and at the moment the stone ballast leveling plate formation is separated from the steel rail. According to the unloading-leveling integrated stone ballast hopper vehicle, the stone ballast leveling device is arranged on the vehicle body, when a middle door unloads stone ballast at the middle position of a rail through wind-driven operation and stone ballast piles are formed, the stone ballast leveling plate formation in the stone ballast leveling device can scrape and level the stone ballast higher than the rail height, rail derailment caused by piled stone ballast is effectively avoided, and leveling while walking of the stone ballast hopper vehicle is achieved.

Description

technical field [0001] The invention belongs to the technical field of railway transportation tools, and in particular relates to an integrated ballast hopper car for unloading and leveling when building railways. Background technique [0002] The ballast hopper car is a special vehicle for transporting ballast and other objects during railway construction, and it is specially used for laying ballast on new lines and maintaining existing railway lines. In order to improve the efficiency of railway transportation, the time for line laying and maintenance is greatly shortened, and higher requirements are put forward for the transportation efficiency and operation safety of ballast hopper cars. [0003] The pneumatic operation of unloading in the middle of the existing stone ballast hopper car is fast, and it is easy to form a pile of ballast in the middle of the track to cause the car to derail. Based on safety considerations, some railway bureaus expressly stipulate that bal...

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
