The structure and tooling of multiple ultra-long guide rails with wide spacing

Abstract

A wide-distance superlong multi-guide rail structured tooling comprises two outer guide rails, a basic guide rail, an inner guide rail and a tooling, wherein the outer guide rails are mounted on a foundation platform in parallel, and the basic guide rail and the inner guide rail are arranged between the outer guide rails. The outer guide rails and the inner guide rail are fixedly mounted on the foundation platform by barrels and connecting bolts nested in the foundation platform. A slider matched with one end of the tooling is mounted on each guide rail, and two ends of the tooling are combined with the sliders of the adjacent guide rails in an adjustable-span connecting manner. Since the two ends of the tooling are combined with the sliders of the adjacent guide rails in an adjustable-span connecting manner, the tooling can mount two different spans of guide rails, and cost is saved. By means of the basic guide rail and the inner guide rail which are used as base for mounting the outer guide rails, the integral accuracy of the four guide rails can be well ensured due to high accuracy of the basic guide rail. In addition, the wide-distance superlong multi-guide rail structured tooling is simple and quick to mount.

Description

Technical field [0001] The invention relates to a wide-spacing multiple ultra-long guide rail structure and tooling suitable for mechanical equipment with wide-spacing and ultra-long parallel guide rails, and in particular to a drive lifting mechanism suitable for large-scale (such as Three Gorges) ship lifts The installation method and tooling of wide-pitch and ultra-long parallel rails required by the comprehensive performance verification test bench for key transmission components (gears, racks). Background technique [0002] The comprehensive performance verification test bench for the key transmission components of the Three Gorges shiplift, gears and racks, is about ten meters in total length, composed of multiple guide rails, one of which is close to six meters in length, and there are four parallel ones. The long guide rails have a span of about two meters, and each guide rail bears about 20 tons. During the test, the mobile platform needs to reciprocate on the guide rail...

Problems solved by technology

[0002] The comprehensive performance verification test bench for gears and racks, the key transmission components of the Three Gorges ship lift drive lifting mechanism, requires a super-long guide rail with a total length of about ten meters. It is composed of multiple guide rails, one of which is nearly six meters long, and there are four parallel guide rails. The ultra-long guide rails have a span of about two meters, and each guide rail bears about 20 tons. During the test, the mobile platform needs to run reciprocally on the guide rails. Therefore, the linear accuracy of each guide rail and the parallel accuracy between the four guide rails, The surface plane precision and other requirements are very high, and its error will directly affect the data collection results during the test, and when the precision is low, the friction force will increase accordingly, and the running resistance will increase, which will affect the service life
