Problems solved by technology

[0009] Another disadvantage is that cup grinding wheels usually have to work on both rails simultaneously for mass balance reasons
This makes it more difficult to perform grinding work on a single rail, such as the center ground rail or the outer power carrying rails of a subway

Embodiment Construction

[0018] As can be seen from the figures, the machine according to the invention basically comprises a base structure 2 mounted on four wheels 4 whose rims 6 can slide on rails 8 to be ground.

[0019] Removably applied to the base structure 2 outside the wheel 4 is a frame 10 supporting the rollers 12, the function of which is to prolong the support plane of the base structure 2 for possible long-wave grinding.

[0020] The horizontal parts of the two L-shaped first frames 18 , which can be lifted vertically by the cylinder-piston unit 16 , can slide on the transverse member 14 of the base structure 2 .

[0021] The first frame 18 can be moved horizontally by a cylinder-piston unit 22 which pushes said first frame 18 outwards until an abutment 24 rigidly connected thereto contacts the head 26 of the rail 8 .

[0022] The vertical and horizontal portions of the first frame 18 are connected together by a curved portion 28 comprising a plurality of holes 30 .

Abstract

A tangential grinding machine slidable on rails to be ground, comprising: - a base structure (2) mounted on wheels (4) slidable on the rails (8) to be ground, - two first frames (18) - two curved portions (28) connecting the two frames (18) and comprising a plurality of holes (30), - a second frame (32) engagable selectively in one of said holes (30) of each curved portion (28), said frame being provided with means (34) for hinging thereto an annular portion (38) to which a plate (46) is rotoidally connected, - means (42, 44) for moving said annular portion (38) relative to said frame (32), - an electric motor (50) positioned on said plate (46), the shaft of said electric motor being connected via a pulley (52) to an abrasive grinding wheel (54) located in a position below said plate (46).

Description

technical field [0001] The present invention relates to a tangential grinder. Background technique [0002] Tangential grinding machines are known for in situ regeneration of worn profiles of rails, comprising a grinding device consisting essentially of a grinding wheel grinding material which, when rotated, removes by abrasion a portion of the material it contacts. [0003] These known machines, i.e. the assembly comprising the grinding device with the grinding tool, the rotary drive member, the adjustment and replacement system, and all other accessory components ensuring correct operation, currently have a series of limitations and disadvantages which the present invention intends to eliminate . [0004] One of these disadvantages arises from the fact that each grinding device usually consists of a disc or wheel of grinding material designed to operate with its peripheral edge. [0005] As this grinding disc wears over time, and thus its working circumference decreases,...
