A compensating overhead rail carrier device for keeping the carrier running horizontally

Abstract

A compensating overhead track carrying apparatus for keeping a carrier running horizontally, comprising a travel track (1) and a compensation track (2) provided in parallel, and a loading travel vehicle running on both the travel track and the compensation track; the loading travel vehicle has travel wheels (3) running on the travel track, compensation wheels (4) running on the compensation track, and bridge frames (5) connected between the travel wheels and the compensation wheels; each bridge frame is provided with a weight bearing point for rotatably connecting the carrier; the travel track bends downward, and the compensation track bends upward; and when the travel wheels of the loading travel vehicle float downwards or upwards as they pass through the bent travel track, the compensation wheels float upwards or downwards in opposite directions with a corresponding amplitude, such that the bridge frames rotate about the weight bearing point thereof, and the horizontal height of the weight bearing point is kept unchanged. The structure of the present invention is simple, reliable and flexible, and can keep the carrier running horizontally on the overhead track in a sagging deformation, thus creating a condition for high-speed transportation on the overhead track.

Description

technical field [0001] The invention belongs to the field of rail transportation, and in particular relates to a compensation type overhead rail carrying device. Background technique [0002] Overhead rail transportation has many advantages that ground transportation cannot match, but it is rarely used in practice. An important reason restricting its development is slow speed and low efficiency. The overhead track is between two support points, and the track will sag and deform due to gravity, so that the vehicle running on the track will rise and fall with the track. If the speed is fast, it will show as violent up and down bumps, which seriously limits the transportation speed and efficiency. If in order to adapt to high-speed operation and improve transportation efficiency, the track must be kept strictly level, which will inevitably make the track heavy: bulky, dense support points, high material consumption, high cost, and great impact on the use of vision and ground ...

AI Technical Summary

Problems solved by technology

The disadvantage is that the mechanism is too complicated and huge, and the degree of track sag is not considered, which will change with the load and the use time of the track

This method is expensive, the mechanism is complicated, and the reliability is not high enough. Once the system fails, it may be completely out of control.

This kind of adjustment range is large, the weight is heavy, and the frequency is frequent, which is bound to be accompanied by a large amount of energy consumption.
