Problems solved by technology

This mechanism provides power for the manual pump manually. When adjusting the rails, the labor intensity of the adjustment workers is high, the automation level is low, and the efficiency is low.
Due to the hydraulic system used for rail adjustment, the performance of the stepless adjustment of the hydraulic cylinder cannot guarantee fine adjustment, and it is easy to under-adjust or over-adjust, resulting in cumbersome adjustment and time-consuming operation.
And because the rail is fixed from below, the continuous adjustment of the deviation point of the rail cannot be realized, and the adjustment accuracy is not high, so it is difficult to realize the inspection and maintenance of long-distance high-speed rail lines

Embodiment

[0032] A ballastless track gauge adjuster, its structure is as follows Figure 1-2 As shown, it includes a controller 19, an electromagnet 1 for adjusting the lifting position, a guide piston rod 20 for limiting the direction of movement, a reference rail clamp 4 for a fixed rail and a movable rail clamp 6 to control the automatic clamping and opening of the above-mentioned track clamps. The hydraulic system is connected to the gauge adjustment mechanism between the reference rail track clamp 4 and the movable rail track clamp 6.

[0033] This ballastless gauge adjuster realizes the automation of gauge adjustment from three actions. The controller 19 controls the electromagnet 1 to energize, so that the guide piston rod 20 is forced to move downward. Under the restriction, ensure that the track adjuster can only move up and down directly above the rail 3. When the track car guide bar 22 and the track car 2 are assembled, the assembly accuracy and strength are guaranteed by th...

Abstract

The invention relates to a gauge regulator for ballastless tracks comprising a controller, electromagnets for regulating lifting and lowering positions, guide piston rods for restricting a moving direction, a reference track clamping-track instrument and a movable track clamping-track instrument for fixing tracks, a hydraulic system for controlling the automatic clamping and unclamping of the reference track clamping-track instrument and the movable track clamping-track instrument and a gauge regulating mechanism connected between the reference track clamping-track instrument and the movable track clamping-track instrument. Compared with the prior art, the gauge regulator for the ballastless tracks can automatically regulate the gauge and can freely walk on the ballastless tracks; and the gauge regulator for the ballastless tracks has the advantages of high precision of the gauge regulating, high efficiency and convenient movement.

Description

technical field [0001] The invention belongs to the technical field of railway maintenance equipment, in particular to a ballastless track gauge adjuster. Background technique [0002] In recent years, with the massive construction and use of high-speed railways, inter-city high-speed railways and urban subways in my country, a considerable part of the railways use ballastless track structures, and the track lines are fixed to the rails by fasteners. The impact of the impact is getting bigger and bigger, and the lateral force generated is more likely to make the gauge of the rail deviate. At the same time, the allowable error value in the gauge acceptance standard is greatly reduced. The important content of ballastless track line laying and daily maintenance is covered. [0003] At present, the manual mode is still used in the maintenance process of ballastless lines, that is, railway maintenance workers use internal combustion engine wrenches, crowbars, gauge rulers and oth...
