Tamping rod additionally provided with torsional spring device and used for railway ballast tamping

Abstract

The invention discloses a tamping rod additionally provided with a torsional spring device and used for railway ballast tamping, and belongs to the field of small railway maintenance equipment. According to the technical scheme, the torsional spring device composed of a connecting sleeve, a bearing, a torsional spring connector I, a torsional spring and a torsional spring connector II is additionally mounted in a flexible shaft tamping rod body; the front end of the connecting sleeve is connected with a rod shell, and the rear end of the connecting sleeve is connected with a hose connector; threads with the screw pitch the same as that of the screwed torsional spring are machined on the torsional spring connector I and the torsional spring connector II, and the torsional spring connector Iand the torsional spring connector II are connected with the torsional spring through the threads; a bearing is mounted outside the torsional spring connector I, and the interior of the torsional spring connector I and a flexible shaft are pressed; the torsional spring connector II and a rolling cone are connected through threads, and a large-play bearing is mounted on the rolling cone. The tamping rod has the advantages that the defects that an existing tamping rod for railway ballast tamping is poor in operation comfort, and a flexible shaft is likely to be broken off are effectively overcome, the service life of the tamping rod is greatly prolonged, and the tamping rod is high in production efficiency, good in tamping effect, high in adaptability, novel in design, reasonable in structure, comfortable in operation, easy and convenient to repair, safe and reliable.

Description

technical field [0001] A tamping rod for railway ballast tamping equipped with a torsion spring device relates to a small-scale railway maintenance machine, in particular to a tamping rod for a flexible shaft tamping machine used for tamping a track bed with ballast. Background technique [0002] At present, the small-scale railway maintenance equipment used for ballasting railway track bed tamping is a variety of tamping machines, especially the most widely used flexible shaft tamping machine. It uses flexible shaft tamping rods to generate vibration, overcome the frictional resistance between the ballasts, make them relatively move and rearrange, and fill the gap under the pillow, so as to achieve the purpose of compacting the ballast and stabilizing the ballast bed. The power source of the tamping machine is separated from the tamping device by a flexible shaft hose, which avoids the operation of the power source in a vibrating state. It is convenient and quick to go up a...
