Steel rail distance regulator

Abstract

The invention relates to a steel rail distance regulator. The steel rail distance regulator comprises a left cylinder block, a right cylinder barrel, a left clamping part and a right clamping part, wherein the left clamping part and the right clamping part are used for clamping steel rails on the two sides, an insulating part is arranged between the left cylinder block and the right cylinder barrel, and the left cylinder block and the right cylinder barrel are fixedly connected through a thread connecting part; the left cylinder block is sequentially provided with a hydraulic cylinder, a reversing valve and a hand-operated pump, a piston rod of the hydraulic cylinder is fixedly connected with the left clamping part, a sliding pulling rod capable of moving in the right cylinder barrel and being locked and fixed is arranged in the right cylinder barrel, and the end portion of the sliding pulling rod is fixedly connected with the right clamping part. The steel rail distance regulator is compact in structure, easy and convenient to operate and capable of adapting to the operating requirements when the height of the bottom faces of the steel rails above the ground is small.

Description

technical field [0001] The invention relates to the technical field of gauge adjustment of steel rails; in particular, the invention relates to a gauge adjuster of steel rails. Background technique [0002] With the opening of the high-speed railway line, the maintenance tools on the line cannot be transported by vehicles, but can only be carried by manpower, and the walking distance is long. Therefore, a light-weight and easy-to-operate rail gauge adjuster is required for line maintenance, especially the use of After the integral ballast bed, the height of the rails from the ground is lower than that of ordinary ballast beds, and some rails are only 25mm from the ground, which puts forward higher requirements for the adjustment of the rail gauge. [0003] Existing rail gauge adjusters can be divided into hydraulic and mechanical thread adjustment methods according to power, and can be divided into hook rail bottom and hook rail waist rail top methods or unilateral adjustmen...

AI Technical Summary

Problems solved by technology

The card seat at the left and right ends of this structure adopts the overall structure of steel structure, which is not only heavy in weight, but also has a high size of the outer card head of the card seat, which has certain requirements for the height of the rail ground from the ground; the hydraulic cylinder is separated from the oil pipe and the hydraulic control pump, making the weight heavy , It is inconvenient to carry; the right pipe is connected by steel pipe, which is long in length and heavy in weight, which greatly increases the weight of the whole machine and is inconvenient to carry.
