Flexible invisible rack track system and method for track logistics vehicle

Abstract

The invention discloses a flexible invisible rack track system and a method for a track logistics vehicle, and belongs to the field of track logistics. The system comprises a track system and a wheel system, wherein the wheel system comprises a driving wheel system and an opposite jacking wheel system; the driving wheel system comprises a driving wheel (5) and a driving gear (6) coaxially mounted; and the driving wheel system and the opposite jacking wheel system are connected through an opposite jacking spring component, so that the driving wheel system is pressed to a space track support surface by an opposite jacking spring (8), and the opposite jacking wheel system is pressed to an opposite jacking surface of a space track by the opposite jacking spring. The track system is provided with a pair of flexible tracks (3) on a large slope section; and as the flexible tracks (3) are higher than a track support surface on the section, the driving wheel (5) is overhead, and the driving gear (6) serves as a driving main piece. The system has the characteristics of simple structure, low manufacturing and operation cost, long service life, high reliability and low impact noise, and is suitable for the working conditions of high load and high-speed operation. The system and the method can be widely applied to the field of local track logistics.

Description

technical field [0001] The invention relates to a flexible invisible rack track system and method for rail logistics vehicles, in particular to a flexible track system that adopts a rail carrying method and is conducive to the safe up and down ramps of large-load rail logistics vehicles, and belongs to the local Rail logistics technology field. Background technique [0002] In the field of local logistics, the rail logistics system is widely used, such as the medical rail logistics system used in the indoor environment of the hospital, and the rail transportation system used in the library and archives. At present, the local rail logistics system generally adopts the structure of double driving wheels, that is, on horizontal tracks or small ramps, the driving wheels driven by friction are used; The gear rack arranged on the ramp meshes with the drive gear to ensure that the rail car goes up and down the ramp smoothly; generally at the beginning of the up and down ramp, the ...

AI Technical Summary

Problems solved by technology

Because, when the drive gear enters the rack, it cannot be accurately guaranteed that the two can mesh together. Therefore, under heavy load and high speed, the rack and the gear will be severely eroded and worn, and a large amount of friction will be generated. Impact noise reduces the reliability of use and greatly increases the cost

In addition, when the track turns left and right, the tooth shape of the rack will become irregular, and it needs to be repaired to achieve proper meshing. Applicability is discounted

[0003] In addition, since the flexible rack is designed and produced according to the standard rack during processing, when it is arranged on the up and down ramps of the track, its tooth shape will change greatly. Even in normal use, due to the flexible Variations in the tooth profile of the rack, resulting in poor meshing and additional wear

In addition, after increasing the moving speed of the rail car, the impact of the driving gear on the flexible rack is further increased, the damage rate of the flexible track is greatly increased, and the impact noise is very large

This will greatly increase the maintenance cost of the track, thus limiting the further improvement of the load capacity and conveying efficiency of the rail car

At present, for the rail conveying system in the field of local logistics, it is required to have a large load capacity and a fast speed. Therefore, the traditional method of using flexible racks to assist up and down ramps has increasingly exposed its limitations.
