Problems solved by technology

[0005] 1. Contact problem, because the pantograph only contacts point by point in extreme cases
[0006] 2. The pantograph will be lifted from the contact rail through the joint
[0007] 3. Causes spark formation, i.e. burning on the pantograph and contact rail
The resulting additional contact problems and wear
[0008] 4. Mechanical wear-planing effect of pantograph and contact rail
[0009] 5. Generate a lot of force and vibration, increase the load on related components, especially the current collector, contact rail, insulator, expansion connector and fixed connector, fixing device on the driving track, etc.
Continuous application of force and vibration can lead to fatigue fracture

Embodiment Construction

[0041] 1 and 1a show two contact rails S adjacent to each other 1 and S 2 , wherein the contact rails in FIG. 1 are connected to each other by a fixed connector, and the contact rails in FIG. 1a are connected to each other by an expansion connector. Unacceptable height deviations of the contact surfaces of the two contact rails occur due to machining tolerances.

[0042] The invention proposes that this deviation be eliminated by grinding the contour K shown in FIGS. 2, 2a and 2b. For this purpose, the contact rail S is raised in the region of the end of the contact rail or to the outside. 1 The contact surface S F1 The removal is carried out by means of the grinding device shown in FIGS. 3-5 according to the previously selected or determined contour, so that a transition from one contact rail to the other is produced almost without deviation.

[0043] In this case, the contour is ground in multiple passes, wherein the pressing element presses the abrasive belt against the...

Abstract

The invention relates to a grinding device (1) for grinding a contact surface (SFi) of a contact rail (Si), wherein the grinding device (1) has an endless abrasive belt (2), wherein the press The tensioning element (5) locally presses the abrasive belt (2) against the contact surface (SFi) of the contact rail (Si) and the pressing element (5) is adjustable at least in the direction of longitudinal extension (X) of the contact rail .

Description

technical field [0001] The invention relates to a grinding device for grinding a contact surface of a contact rail and a method for eliminating deviation of the ends of two contact rails adjacent to each other by means of the grinding device according to the invention. Background technique [0002] Contact rail installations are used to transfer electrical energy from the roadway to vehicles moving on it. Vehicles moving in the lane have current collectors and pantograph / receptor contacts that are contacted by contact rails. The contact rail system consists of contact rail parts, which are connected to each other at the joints by means of fixed and expansion connectors. During the manufacture and installation of contact rail systems, the contact surfaces can be misaligned at the joints, as shown in Figures 1 and 1a. [0003] The reasons for the deviation are, on the one hand, the height tolerances of the contact rails and the tolerances on connection systems such as fixed ...
