Wing rail clamp

Abstract

The invention provides a wing rail clamp. The wing rail clamp comprises a lifting lug for being connected with a lifting device, a first movable arm, a second movable arm, a first clamping arm and a second clamping arm. The first movable arm and the second movable arm are hinged to the lifting lug through a first hinge shaft. The first clamping arm and the second clamping arm are hinged to the first movable arm and the second movable arm. The first clamping arm and the second clamping arm are hinged through a second hinge shaft to form an intersection. The ends of the first clamping arm and the second clamping arm are configured into hook shapes, a clamping part for clamping a wing rail is formed by the ends of the first clamping arm and the second clamping arm jointly, the opening degreeand the clamping force of the clamping part can be adjusted by lifting the wing rail clamp through the lifting lug, and therefore the wing rail is clamped.

Description

technical field [0001] The invention relates to the technical field of turnout manufacturing industry, in particular to a wing rail clamp. Background technique [0002] With the development of railway technology, wing rails are widely used in frog structures of turnouts. [0003] The wing rail rail itself belongs to the asymmetric cross-section rail, and the finished product after machining is in a tilted state after being hoisted. Therefore, when clamping, the rail waist at the end of the wing rail cannot be vertically inserted into the guide rail fixture, and it is very difficult to clamp the wing rail into the general 60kg / m rail guide rail fixture. [0004] In addition, there are problems in the heat treatment process of rolled wing rails that affect safety production, product quality and production efficiency. For example, when lifting, because the rail parts are in a tilted state, it is difficult to insert the guide rail clamps clamped by the rail limbs and the rail b...

AI Technical Summary

Problems solved by technology

Therefore, when clamping, the rail waist at the end of the wing rail cannot be inserted vertically into the guide rail fixture, and it is very difficult to clamp the wing rail into the general 60kg / m rail guide rail fixture

[0004] In addition, there are problems in the heat treatment process of rolled wing rails that affect safety production, product quality and production efficiency. For example, when lifting, because the rail parts are in a tilted state, it is difficult to insert the guide rail clamps clamped by the rail limbs and the rail bottom. , so usually the splint reformed guide rail fixture is used to plug the insulating sheet

The current operation will lead to poor heat treatment quality of the end, and there is a hidden danger of ignition and overburning of the quenched end

At the same time, the finely adjusted wing rails are prone to distortion and deformation when lifted, resulting in changes in the size of the wing rails
