Description

A kind of rolling stock and its pipeline protective device
Technical field
The present invention relates to technical field of engineering machinery, in particular to a kind of rolling stock and its pipeline protective device.
Background technique
The type of domestic and international rail transporter is varied, and in a kind of typical railway transport vehicle, chassis includes Two parts: end fixed frame and rotation load chassis, and rotation loads chassis can be after opposed end fixed frame be lifted upwards It is rotated around vertical axis.
Generally, the driving, braking and driving rotation of above-mentioned rolling stock load chassis lifting and rotate hydraulic dynamic Power source is installed on end fixed frame, connects the control of rotation loading chassis with the pipeline that hydraulic tube is constituted by more brake pipes Element.Usual relationship is longitudinally arranged to be loaded between chassis in end fixed frame and rotation.
In order to meet the rotation function that rotation loads chassis, it is arranged in end fixed frame and rotation loads between chassis The linear distance when length of pipeline is naturally larger than vehicle normal transport between hydraulic power supply and control element, i.e., it is each in pipeline The downward hanging of pipeline is on chassis, and in this way in driving, pipeline is easy to and ground face contact, and then is worn, and leads to hydraulic oil Phenomena such as leakage.
Therefore, the structure for how improving existing rolling stock avoids being arranged in end fixed frame and rotation loads chassis Between pipeline worn with ground, be those skilled in that art's technical problem urgently to be resolved.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of pipeline protective device of rolling stock, including bracket, it uses In the pipeline for supporting the rolling stock, the both ends of the bracket are respectively arranged with the first rotation section and the second rotation section, institute It states the first rotation section and second rotation section and is respectively supported at the end underframe and rotation chassis of rotation rolling stock, and phase The two is answered to be rotatablely connected in perpendicular and horizontal plane, the bracket is scalable along its length.
When pipeline protective device provided by the present invention is applied to rolling stock, end underframe and rotation can will be connected to For pipeline support between chassis on bracket, bracket is individually fixed in end by first rotation section and the second rotation section at its both ends On portion's chassis and rotation chassis.In this way when the rotation chassis opposed end chassis of rolling stock is relative to jacking rotation, Yin Benfa The both ends of bracket in bright pass through the first rotation section and the second rotation section respectively and are putting down vertically with end underframe and rotation chassis Rotation connection in face and horizontal plane, and with the rotation of rotation chassis, bracket can gradually extend along its length, therefore can Meet the needs of rotation chassis lifting rotation.
When rotating chassis completion loading-unloading vehicle rotation recovery driving status, the both ends of bracket are first in horizontal plane opposed end Chassis and rotation chassis rotation, and with rotation chassis rotation, the length of bracket is gradually reduced to adapt to length over ends of body and satisfaction Rotation requires, and when rotation chassis, which is turned to, is in same linear position with end underframe, rotation chassis is gradually fallen after rise, is rotating During chassis is gradually fallen after rise, the both ends part of bracket relatively rotates respectively a little to be rotated in perpendicular, finally rotates bottom Frame restores driving status.
