Railway vehicle, sliding plug door and handle locking device thereof

Abstract

The invention discloses a sliding plug door of a railway vehicle. The railway vehicle comprises a vehicle body and the sliding plug door arranged on the vehicle body, wherein the sliding plug door comprises a door body and a door body locking device; the door body locking device is driven by a handle to ensure that the door body and the vehicle body are locked; the sliding plug door also comprises a handle locking device with two working states including a locking state and an unlocking state; the handle locking device limits the rotation of a handle when in the locking state; and the handle can freely rotate when the handle locking device is in the unlocking state. The sliding plug door is provided with the handle locking device, so that the conditions of automatically opening the door body and scattering goods in the vehicle body in the vehicle driving process when the handle locking device is in the locking state are avoided, and the safety performance of the sliding plug door is improved. The invention also discloses the handle locking device of the sliding plug door and the railway vehicle with the sliding plug door.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a railway vehicle, a sliding door and a handle locking device thereof. Background technique [0002] The plug doors of railway wagons have multiple forms, and their common feature is plug-in locking. The way to open the door is to move the door laterally outside the car body to a distance greater than the thickness of the car door, and then pull the door longitudinally along the car body to open the door. The reliability of plug-in locking of sliding doors determines the safety of driving and the safety of goods on the vehicle. [0003] A typical salamander such as Figure 1-3 As shown, among them, figure 1 It is a partial sectional view of a sliding door in the prior art; figure 2 It is a partial cross-sectional view of the sliding door in the prior art in an unlocked state; image 3 It is a partial sectional view of the sliding door in the prior art in a locked st...

AI Technical Summary

Problems solved by technology

When the vehicle vibrates during operation, the T-shaped thread is prone to loosening. When it is loosened to the unlocked state and receives a lateral force, the door moves laterally. At the same time, under the action of vehicle traction and braking force, the door moves along the slideway. When the door is opened, the goods in the car body may be scattered, so that the driving safety and the safety of the goods cannot be guaranteed.
