Elastic traction rod device for steel rail grinding trolley

Abstract

An elastic traction pull rod device for a steel rail grinding trolley is characterized in that a first end cover is arranged on a flange plate through a bolt and a nut; the right end of the piston rodis inserted into a center hole of the cylinder barrel through the first end cover, the elastic element is installed on the piston rod, and the piston and the right end of the piston rod are installedtogether. A first shaft hole is formed in a left end screw of the piston rod; a first knuckle bearing is mounted in a first bearing base at the left end of the first shaft; a second end cover is welded to the right end of the cylinder barrel, and a second knuckle bearing is installed in a second bearing base on a second shaft to form a first elastic traction rod device; the two ends of a first elastic traction rod device are hinged to a first lug ring and a third lug ring in the traction vehicle body and the polishing trolley respectively, and the two ends of a second elastic traction rod device of the same structure are hinged to a second lug ring and a fourth lug ring in the vehicle body and the polishing trolley respectively. And the elastic traction rod device for the steel rail grinding trolley is formed.

Description

technical field [0001] The invention relates to railway maintenance machinery, in particular to an elastic traction rod device for a rail grinding trolley. Background technique [0002] When the rail grinding car is grinding, it needs to put the grinding trolley on the rail, and it is connected with the main car body by a pull rod. At present, there are two ways to set the traction rod of the grinding trolley. The first way is to put the grinding trolley One end is drawn by a stretchable elastic traction rod, while the other end is drawn by a rigid traction rod that cannot be stretched. When the traction rod is pulled by the main vehicle body, the elastic element of the traction rod in the forward direction will be compressed and transmit traction. The traction rod at one end does not apply thrust to the grinding trolley; the second method is to use only one rigid traction trolley to pull the grinding trolley, so when the grinding trolley runs in both directions, when the ri...

[0002] When the rail grinding car is grinding, it needs to put the grinding trolley on the rail, and it is connected with the main car body by a pull rod. At present, there are two ways to set the traction rod of the grinding trolley. The first way is to put the grinding trolley One end is drawn by a stretchable elastic traction rod, while the other end is drawn by a rigid traction rod that cannot be stretched. When the traction rod is pulled by the main vehicle body, the elastic element of the traction rod in the forward direction will be compressed and transmit traction. The traction rod at one end does not apply thrust to the grinding trolley; the second method is to use only one rigid traction trolley to pull the grinding trolley, so when the grinding trolley runs in both directions, when the rigid trolley runs in the direction of the rigid trolley, the grinding trolley is in a state of being driven. In the pulling state, it has better running stability, and in the reverse direction, it is in the pushed state; because the grinding trolley has poor running stability in the pushed state, it is easy to cause unstable grinding quality, especially when grinding curved tracks , it is easy to cause the derailment of the grinding trolley. In order to ensure the quality and safety of the rail grinding operation, it is necessary to improve the existing traction rod device of the grinding trolley
