Railway cold-chain logistics bi-directional parallel pipeline system and control method

Abstract

The invention discloses a railway cold-chain logistics bi-directional parallel pipeline system. A cold-chain conveying pipeline comprises a first cold-chain conveying pipeline and a second cold-chainconveying pipeline which are arranged in parallel at least at part of a district, and the tail ends are provided with a sending device and a receiving device correspondingly. The first cold-chain conveying pipeline and the second cold-chain conveying pipeline are arranged in parallel up and down, and the middles of the first cold-chain conveying pipeline and the second cold-chain conveying pipeline are provided with a self-rotating reversing device and a rotary drive device. The self-rotating reversing device is internally provided with a first transition pipeline and a second transition pipeline which are arranged in parallel and are integrally and fixedly connected. The rotary drive device is used for synchronously rotating the two transition pipelines and cold-chain container devices inthe transition pipelines to be reversely switched between the first cold-chain conveying pipeline and the second cold-chain conveying pipeline. By means of rotation of the transition pipelines, whenthe cold-chain container device carries out reversing, smoothness of the bi-directional parallel pipelines can be kept, and bi-directional transmission of the parallel pipelines is achieved.

Description

technical field [0001] The invention belongs to the field of railway cold chain logistics, and in particular relates to a two-way parallel pipeline system and control method for railway cold chain logistics. Background technique [0002] While the rapid development of modern logistics technology brings convenience to people's lives, people's diverse needs also give birth to the progress of existing logistics technology and the birth of new logistics technology, such as cold chain logistics technology. Cold chain logistics refers to the organic combination of transportation, storage, loading and unloading, packaging, circulation processing, distribution, information processing and other functions during the physical flow of frozen goods from the supply point to the receiving point. Cold chain logistics has higher and more complex requirements than ordinary room temperature logistics systems, and the construction investment is much larger. It is a huge system project, and its ...

Problems solved by technology

However, this type of pipeline can only transport fluid substances such as gas and liquid, and cannot meet the transportation needs of solid goods.

[0005] Furthermore, in the field of railway cold chain logistics, there is no relevant report on the use of pipeline transportation; while in the field of traditional pipeline transportation, there has never been any relevant application in the field of railway cold chain logistics. The two-way parallel pipeline transmission and the reversing switching between the two-way parallel pipelines in the middle section are even less involved.
