Elastic fastener capable of accurately adjusting rail gauge of steel rail

Abstract

The invention discloses an elastic fastener capable of accurately adjusting the rail gauge of a steel rail, and particularly relates to the field of rails. The elastic fastener comprises a rail, a hexagonal screw is detachably mounted on the bottom surface of the rail, a pointer is fixedly mounted at the bottom of the hexagonal screw, a bottom block is movably mounted at the bottom of the rail, and a fixing pin is movably mounted on the right side of the bottom block; and the left side of the rail is in threaded connection with a left side screw, the top of the bottom block is provided with centimeter and millimeter marks, the bottom of the fixing pin is in engaged connection with a movable plate, and the top of the fixing pin is detachably provided with a right side screw. According to the invention, the movable plate and the pointer are combined for use, so that movable plate top connecting teeth and movable plate bottom connecting teeth are engaged with a gear for left-right adjustment, and the pointer and centimeter marks are arranged, so that precision adjustment can be achieved when the steel rail spacing is adjusted, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rails, and more specifically, the invention relates to an elastic fastener capable of precisely adjusting the gauge of a steel rail. Background technique [0002] Gauge is the distance between two rails on a railway track. The distance between the rails is based on the inner distance of the rails. Now there are many different gauges in the world, which are divided into ordinary rails, wide rails, and narrow rails. Rails are the main components of railway tracks. Components, whose function is to guide the wheels of the rolling stock, withstand the enormous pressure of the wheels, and transmit them to the sleepers. The rails must provide the wheels with a continuous, smooth and least resistance rolling surface, including a precisely adjustable rail distance elastic fasteners, [0003] But it still has some shortcomings when using the rails in practice, as in the existing device, because the distance needs ...

Problems solved by technology

[0003] But it still has some shortcomings when using the rails in practice, as in the existing device, because the distance needs to be adjusted between the rails, and the rails are mostly fixed and inconvenient to operate, and because of the need for precision, it is necessary to adjust the distance between the rails. During the adjustment process, it is impossible to adjust the precision of the rail, which reduces the work efficiency and is not easy to operate
