Description

Technical Field

[0001] The utility model relates to the technical field of railway track adjustment tools, in particular to a device capable of measuring and assisting in adjusting the width of a turnout guard rail wheel flange groove. Background Art

[0002] A guardrail is a steel rail installed inside the track rail that doesn't bear the vertical wheel load. Its function varies depending on where it's installed. At a switch frog, the guardrail is placed inside the rail opposite the dangerous space in the frog. It guides the wheels through the dangerous space, preventing them from striking the fork tip and reducing wear on the outer rail. The gap between the guardrail's active surface and the base rail's active surface is the guardrail flange groove. If the width of the guardrail flange groove exceeds the specified value, manual adjustment is required.

[0003] During routine turnout inspections and back guard adjustments, steel rulers are used for measurement, which results in large errors. During adjustment, the dimensions are basically controlled by the gaskets and the removal of the pieces. It is necessary to repeatedly tighten and loosen the guard rail bolts and measure repeatedly to achieve the target dimensions, which results in a large workload. When installing the guard rail adjustment piece, a crowbar must be used to separate the guard rail from the rail support, and there are safety risks in the installation of the guard rail adjustment piece. In existing guard rail wheel flange groove width adjustment devices, a Chinese utility model patent with patent number CN202120474991.2 discloses a railway guard rail insert adjuster, comprising a card plate, the card plate being U-shaped, a bent portion being provided on one side of the card plate, a straight portion being provided on the other side of the card plate, a nut being fixed to the top of the straight portion, a threaded rod being threaded in the nut, a connector being fixed to one end of the threaded rod, and a bearing being fixed to the other end of the threaded rod. While this device can adjust the width of the guardrail wheel flange groove, it still has the following problems: 1. Once installed, the device can only reduce the width of the guardrail wheel flange groove, not increase it. When adding or removing guardrail inserts, the device cannot move the guardrail toward the rail support to clamp the inserts. It can only be pulled by tightening the guardrail's transverse bolts. The guardrail's transverse bolts are located low, making operation inconvenient, and pulling the guardrail with the transverse bolts can easily damage the bolts. 2. The device lacks a gauge to measure the amount of adjustment, so the amount of adjustment cannot be observed in real time during the adjustment process. Summary of the Invention

[0060] Step 4: After inserting the guardrail adjustment piece, rotate the handle counterclockwise to tighten the gap between the guardrail 9 and the rail support and read the return wheel flange groove width value using the measuring ruler 6.

[0061] Step 5: After adjustment, use a lithium-ion wrench to tighten the horizontal bolts of guardrail 9 one by one to the standard torque.
