TIE TAMPER WORKING MEMBER TOOL Russian patent published in 2005 - IPC

FIELD: railway transport; permanent way maintenance and repair facilities.

SUBSTANCE: invention relates to tie tamping machines used to consolidate track ballast. Proposed tool of tie tamper has body with blade equipped with hard-alloy plates over entire area of part of area of front or front and rear surfaces. Hard-alloy plates arranged over periphery of front and rear surfaces of blades are made of material featuring higher impact strength, cracking resistance, plastic deformation specific work and bending strength or combination of said parameters as compared with the rest of plates. Plates featuring different impact strength, cracking strength, plastic deformation specific work and bending strength or combination of said parameters, are installed on different sections of peripheral part of front or front and rear surfaces of blade. Extreme lower plates are made arc-shaped between side wall and lower wall of blade. Edges are rounded off at intersection of side surfaces of all plates. Intersections of side and rear surfaces of plates are either provided with chamfer or are rounded off. All front intersections of side surfaces of said or/and the rest of plates are rounded off, intersections of their side and rear surfaces are either provided with chamber or rounded off. Blade is either made curvilinear or is provided with front slope to side of decrease of length of blade lower side at sides and in places of intersection of sides with lower side. Plates arranged at least over periphery of front surface of blade are provided with projections.

EFFECT: increased service life and improved serviceability of tool.
