A new type of sealing device for side doors of railway wagons

Abstract

The invention discloses a novel sealing device for side doors of a wagon. The novel sealing device structurally comprises the right side door, an anti-collision device which can seal the side doors conveniently, a cross strip, a cross plate, an upper sliding rail, transparent glass, a left handle, a rubber sleeve, the left side door and a lower sliding rail. The cross plate is welded to the rightend of the front face of the left side door, and the transparent glass is embedded at the upper end of the front face of the left side door. The left handle is welded to the middle section of the front face of the left side door, and the front end of the left handle is sleeved with the rubber sleeve in an inserting mode. The lower end of the left side door is in clearance fit with the lower sliding rail, and the upper end of the left side door is in sliding connection with the upper sliding rail. The upper end of the right side door is in clearance fit with the upper sliding door, and the lower end of the right side door is in sliding connection with the lower sliding rail. The most of the extrusion force is offset when goods are in contact with the anti-collision device by means of the anti-collision device for sealing the side doors conveniently, the anti-collision device is subjected to extrusion force in an acceptable range, the safety of the side doors is ensured, and a coordination block is movable and can buckle the cross plate so that the side doors can be sealed.

Description

technical field [0001] The invention is a novel sealing device for a side door of a railway freight car, which belongs to the field of railway freight cars. Background technique [0002] Freight transportation is an important part of railway transportation. The vehicles used to carry goods on the railway are collectively called railway freight cars.
