Wear-protection device for a protective guide or steering plate

Abstract

A wear-protection device for a protective guide or steering plate with a steel plate, which has at least one front face subjected to a load and lateral surfaces, which are separated by edge areas. The lateral surface is covered, at least partially, by a lateral wear-protection device which has at least one wear-protection element on each lateral surface. On the front face subjected to a load by a front wear-protection device formed by at least one wear-protection element, the wear-protection element for the front face subjected to a load has a substantially angle-like cross section with a leg at the front and a lateral leg, and the edge area of the steel plate is surrounded at least partially by the wear-protection element. In this embodiment, the wear protection of the protective guide and steering plate against shocks in the edge area is improved, which extends the service life of the protective guide and steering plate.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a wear-protection device for a protective guide or steering plate with a steel plate, which has at least one front face subjected to a load and lateral surfaces, separated by edge areas, wherein the lateral surface is covered, at least partially, by a lateral wear-protection device which has at least one wear-protection element on each lateral surface and on a load-bearing front face by a front wear-protection device formed by at least one wear-protection element. [0003] 2. Discussion of Related Art [0004] Protective guides or steering plates are used, for example, in track repair machinery in connection with railroad track construction, or are employed as mixing blades in mixing installations for concrete, cement, gravel, sand, stone chips, asphalt or other abrasively acting bulk materials. [0005] In general, the protective guides or steering plates are subjected to great mechanical stress...

AI Technical Summary

Benefits of technology

The invention provides a wear-protection device for protective guides and steering plates that improves wear protection and extends service life. The device has a wear-protection element with a cross-section that surrounds the front and lateral edges of the protective guides and steering plates. This reduces erosions and prevents damage to the components. The wear-protection element has an angle-shaped cross-section, which simplifies positioning during soldering and reduces the need for maintenance. The front and lateral legs of the wear-protection element can have different lengths, and the cross-section of the material can remain the same. The wear-protection element can be designed as a quarter-circle profile or with beveled edges. The ratio of wear-protection elements can be at least 2:1. The wear-protection device can be used in construction machinery and mixing installations.

Problems solved by technology

Displacement of the transition area leads to a clear reduction of erosions, so that coarse-grained particles, in particular, can no longer penetrate between the individual wear-protection elements.
