A hydraulic gauge adjuster

Abstract

The invention discloses an adjuster and aims at providing a track gauge adjuster. According to the track gauge adjuster, relatively long tracks can be stably moved in one time, and an ideal storage function can be realized. According to the key point of the technical scheme, a main hydraulic cylinder is connected with an external hydraulic power supply, a main hydraulic chamber is formed in the main hydraulic cylinder, a main plunger rod is hermetically and slidably connected in the main hydraulic chamber, a slipping end and an output end are arranged on the main plunger rod, and a secondary hydraulic chamber is formed in the output end and comprises a left secondary chamber and a right secondary chamber; a left plunger rod is hermetically and slidably connected in the left secondary chamber, a left plunger chamber is formed in the left plunger rod, and a left ejector rod is hermetically and slidably connected in the left plunger chamber; a left auxiliary chamber is formed in the left plunger chamber, and a left auxiliary rod is heremtically and slidably connected in the left auxiliary chamber; a right plunger rod is hermetically and slidably connected in the right secondary chamber, a right plunger chamber is formed in the right plunger rod, and a right ejector rod is hermetically and slidably connected in the right plunger chamber; the left auxiliary chamber is formed in the right secondary chamber, and a right auxiliary rod is hermetically and slidably connected in the right auxiliary chamber; the slipping directions of the left ejector rod, the left auxiliary rod, the right ejector rod and the right auxiliary rod are accordant with the slipping direction of the main plunger rod.

Description

technical field [0001] The invention relates to a position adjusting device, more specifically, it relates to a gauge adjuster capable of stably moving long rails at one time and realizing an ideal storage function. Background technique [0002] With the speed-up of domestic railway passenger trains and the construction of high-speed passenger dedicated lines, the allowable deviations of the railway line gauge acceptance standards have been stipulated accordingly, and the deviation values ​​have been greatly reduced. Technical requirements, gauge adjustment is one of the operations involved in daily maintenance and repair of public works. [0003] In the early gauge adjustment, a double-headed threaded rod was often used to span the two rails of the line. With one rail as a fixed reference, the sleeper fastener on the other side was loosened, and the double-headed rod in the middle of the rod was manually pulled. Barrel nuts are used to extend or shorten the rods to achieve...

AI Technical Summary

Problems solved by technology

Because the plunger pump and the oil tank are set separately, the diverter with this structure has poor overall structure compactness, large volume, heavy weight, and is inconvenient to carry.

Moreover, an oil pipeline connecting the plunger pump and the fuel tank needs to be set, resulting in high production costs.

[0005] In view of the above technical problems, the Chinese patent application number 200920304411.4 is a manual hydraulic gauge adjuster suitable for sleepers with Pandrol fasteners, including a base, a plunger pump and an oil tank on the base, and a plunger on the base Oil cylinder, the plunger cylinder is provided with a plunger protruding from its outside, the plunger cylinder and the plunger pump are connected through the oil pipeline, and the end side of the base close to the plunger is provided with a connection for clamping with the rod-shaped body According to the attached drawings, it is known that the plunger cylinder on the base pushes the rail against it to move through the plunger to achieve the final gauge adjustment. However, as we all know, the rail has a long length, so a single plunger cannot stably move the entire length of the rail at once
