AI Technical Summary

Technical Problem

Existing crane runway supports struggle to independently adjust the height and angular position of the bearing element relative to the base element, leading to misalignment and potential deflection of rails under heavy loads.

Method used

A rail bearing with an adjustable compensating device comprising a joint assembly and a support column, allowing independent adjustment of the bearing element's vertical and angular positions relative to the base element, using a mechanical series connection that includes a ball joint or pivot joint to enable precise alignment and fixation.

Benefits of technology

Enables precise horizontal and vertical alignment of rails, compensating for structural deviations and preventing deflection under heavy loads, with enhanced stability and adjustability.

Abstract

A rail bearing (1) comprises a bearing element (4) for supporting a rail (2), a base element (5) for attachment to a support structure (3), and an adjustable compensating device (25) that aligns the bearing element (4) relative to the base element (5) and supports it on the base element (5) in the direction of a vertically oriented virtual principal axis (36) of the rail bearing (1). The compensating device (25) allows for adjustment of the height and angular position of the bearing element (4) relative to the base element (5). For this purpose, the compensating device (25) includes a mechanical series connection, aligned along the principal axis (36), of a joint assembly (26) that can be locked by clamping its components against each other, and a support column (27) whose length can be varied by screwing it in along the principal axis (36).The unblocked joint arrangement (26) allows the bearing element (4) to pivot relative to the base element (5) about any pivot axis (44) that intersects the main axis (36) at a right angle at a predetermined pivot point (35); and a screw-in position of the support column (27) is fixed by the rail (2) mounted on the bearing element (4).
