Windshield at car end of rail vehicle and its installation and use method

Abstract

The invention provides a railway vehicle end internal windshield and an installation method thereof and a usage method thereof. A complete double-layer closed capsule over-all structure is adopted, and capsules are connected with frames in a sliding mode. Not only can the sound reduction index of the internal windshield be improved, but also the problems that the capsule generates large deformation and is damaged when a train passes through curves are avoided. The internal windshield comprises a set of frames, the capsules, a top plate, a bottom transition plate and side protective plates, wherein the set of frames are longitudinally connected between the outer side of the end portion of a vehicle body and a nearby internal windshield, the capsules are arranged on the frames, and the side protective plates are arranged on two sides of the internal windshield. The capsules comprise outer layer capsules and inner layer capsules which are in overlapping joint with each other in an embedded mode and are connected into a whole. The outer layer capsules and the inner layer capsules form a complete double-layer closed sound insulation entire structure between one set of frames. The inner layer capsules are connected with the frames in a sliding mode. The internal windshield mainly plays a role of realizing noise reduction, and the double-layer capsules can substantially improve the entire sound reduction index, and enables noises of the vehicle end to be controlled within a standard range.

Description

technical field [0001] The invention relates to an inner windshield applied to a rail vehicle and an installation and use method thereof, specifically adopts double-layer noise control treatment to greatly improve the sound insulation of the inner windshield, and belongs to the technical fields of machinery manufacturing and rail transit. Background technique [0002] With the rapid popularization of domestic urban rail transit and the substantial increase in vehicle speed, higher design and use requirements are put forward for improving the comfort of the passenger interior environment. [0003] In the existing rail vehicle structure, an inner windshield is connected between the ends of the two car bodies to provide a passage for personnel to pass through, and to perform performance treatments such as sealing, heat preservation, and noise reduction, that is, through the butt joint of the inner windshield. The car body is actually connected. [0004] At present, the inner w...

AI Technical Summary

Problems solved by technology

[0007] The windshield at the vehicle end of the rail vehicle and its installation and use method according to the present invention aim to solve the problems in the above-mentioned prior art by adopting the overall structure of a double-layer closed capsule around the entire circumference, and adopt a sliding connection mode between the capsule and the frame , which can not only significantly improve the sound insulation of the inner windshield, but also avoid the problem of large deformation and damage of the capsule when passing the curve
