Railway vehicle and safety handrail thereof

Abstract

The embodiment of the invention relates to the technical field of railway vehicles, and concretely relates to a railway vehicle and a safety handrail thereof. The safety handrail comprises an outer pipe and an inner pipe. Wherein the inner pipe is provided with a first end and a second end which are oppositely arranged, the first end can be installed in the outer pipe in a sliding mode, and the second end is provided with a locking hole; a limiting sleeve is fixedly connected to the end face, facing the inner pipe, of the outer pipe, a hinge joint is detachably installed at the end, away from the inner pipe, of the outer pipe, and the limiting sleeve is used for limiting the first end of the inner pipe into the outer pipe; and the outer circumferential face of the outer pipe is sleeved with a warning sign capable of rotating around the axis of the outer pipe. The safety handrail has the advantages of being adjustable in length and small in occupied space in the width direction of the passing door during retracting, the situation that the designed width of the passing door is large can be met, and the passing efficiency of the passing door can be improved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular, to a rail vehicle and a safety handrail thereof. Background technique [0002] Existing rail cars generally install safety handrails at the passing doors at the end of the car; when the safety handrails are placed horizontally at the door, passengers can be intercepted and warned by the safety handrails; and when passengers and staff need to pass, the safety handrails can be rotated to the vertical position. The existing safety handrails at the end of the car all adopt a single-rod structure, and the mounting seat at the end of the fixed safety handrail is fixed on the passing door column through two fixed points, the upper and the lower. [0003] The width design of the door at the end of the car needs to meet the requirements for passengers to pass through, and it is generally greater than 28 inches, that is, 711.2mm. The height of the safety handrail is require...

AI Technical Summary

Problems solved by technology

However, when the width of the passing door exceeds the installation height of the safety handrail from the floor surface, the safety handrail will interfere with the floor surface when retracted, resulting in failure to meet the use requirements

[0004] To sum up, the existing safety handrail with single-pole structure is only suitable for the case where the width of the passing door is smaller than the installation height of the handrail rod. When the design width of the passing door is large, the single-pole handrail cannot meet the requirements of use
