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.

Example Embodiment

[0007] Combine figure 1 The details and working process of the present invention are described in detail. Install a torsion spring device consisting of a connecting sleeve 2, a bearing 3, a torsion spring joint 7, a torsion spring 8 and a torsion spring joint 9 in the flexible shaft tamping rod; the front end of the connecting sleeve 2 is connected to the rod shell 11, and the rear end is connected Hose joint 4; Ⅰ torsion spring joint 7 and Ⅱ torsion spring joint 9 are made with threads with the same screw torque as torsion spring 8 after tightening, and are connected with torsion spring 8 through this thread; Ⅰ torsion spring joint 7 is equipped with bearing 3 , The inner is compressed with the flexible shaft 6; the Ⅱ torsion spring joint 9 is connected with the roller cone 10 by thread, and the roller cone 10 is equipped with a large clearance bearing 1. One end of the hose 5 is connected with the hose connector 4, the rod shell 11 and the pick body 13 are connected by threads, and the pick body 13 and the pick 14 are connected by threads. The flexible shaft 6 is threadedly connected with the roller cone 10 through a torsion spring joint 7, a torsion spring 8, and a torsion spring joint 9, and is supported on a bearing 1 with a large clearance. During railway maintenance operations, the power of the tamping machine drives the cone 10 to rotate through the flexible shaft 6 in the flexible shaft tamping rod. The cone 10 rotates while rotating along the inner cone surface of the raceway 12 fixed in the rod shell 11. The pure rolling revolution of sliding produces centrifugal force, that is, the exciting force passes through the rod shell 11 and the pick body 13 to the pick head 14 to tamping the ballast of the ballast, overcoming the frictional resistance between the ballasts, causing them to move and rearrange relative to each other, and the space under the pillow Fill it up to achieve the purpose of compacting the ballast and stabilizing the ballast bed. Compared with the existing flexible shaft tamping rod, the additional torsion spring device consisting of connecting sleeve 2, bearing 3, Ⅰ torsion spring joint 7, torsion spring 8 and Ⅱ torsion spring joint 9 makes the transmission stable and improves the operation Comfort, avoiding the early breaking of the flexible shaft, solving the long-standing problem for the railway track bed tamping construction, and will surely produce significant economic and social benefits. The beneficial effects of the present invention are: it effectively solves the disadvantages of the existing tamping rods used for railway ballast tamping, such as poor operating comfort and easy breakage of flexible shafts, greatly improving their service life, high production efficiency and good tamping effect. Strong adaptability, novel design, reasonable structure, comfortable operation, easy maintenance, safe and reliable.
