Flexible self-adaptive device of cold chain logistics pipeline unit load device and pipeline system

Abstract

The invention discloses a flexible self-adaptive device of a cold chain logistics pipeline unit load device. A cold chain unit load device (3) runs in a cold chain transmission pipeline (2), a cold chain cargo compartment is arranged in the cold chain unit load device (3), the cold chain cargo is loaded in the cold chain cargo compartment, and flexible self-adaptive devices (1) are mounted in thecold chain unit load device (3) in the back and forth direction; and each flexible self-adaptive device (1) comprises a plurality of sets of multi-linkage mechanisms distributed in the circumferentialdirection of the cold chain transmission pipeline (2), an elastic mechanism and rollers (106), and the elastic mechanism at least drives the multi-linkage mechanisms to make the rollers (106) closelybe attached to the inner pipe wall of the cold chain transmission pipe (2). The flexible self-adaptive device breaks through the limitation of the fluid pipeline, realizes the pipeline transmission of the cold chain cargoes, further realizes the flexible self-adaption of the cold chain unit load device in the pipeline transportation process, and improves the transportation stability, safety and reliability.

Description

technical field [0001] The invention belongs to the field of new urban rail transit, and in particular relates to a flexible self-adaptive device for a cold chain logistics pipeline system container. 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. The scope of application of cold chain logistics includes: primary agricultural products (vegetables, fruits; meat, poultry, eggs; aquatic products, flower products), processed food (quick-frozen food, pou...

AI Technical Summary

Problems solved by technology

[0008] 1. The diameter of the cold chain transmission pipeline will change uncertainly due to pipeline processing errors, installation errors, etc. , settlement problems, external loads and other complex factors, there may be misalignment or gaps at the joints of cold chain pipelines; Friction mode transmission or traditional fixed wheel transmission will cause large jumps or vibrations or even severe impacts at the joints of cold chain pipes, which will seriously affect the stability, reliability, and safety of transportation, and it is easy to affect the transportation. The quality of cold chain goods is damaged, and at the same time, the structure of the cold chain container is destroyed, which greatly shortens its service life and increases transportation costs;

[0009] 2. There are bends in the cold chain pipeline. In order to ensure that the conventional friction mode transmission or the traditional fixed wheel transmission can pass the curve, it is necessary to leave a radial gap. However, the cold chain container cannot be close to the inner wall of the pipeline. In the straight road, the cold chain container is prone to shaking and impact, especially when the straight road turns into a curve at high speed, the cold chain container and the cold chain goods will be directly impacted by physical impact, destroying the mechanism of the cold chain container, Even violent contact and friction with the pipeline will change the ambient temperature in the cabin and damage the cold chain cargo;

[0010] 3. Further, there are mutual constraints in pipeline processing technology, pipeline installation process and external conditions, pipeline curvature design, structural design of cold chain container, operation speed management, etc., which seriously increase the design burden and construction cost, limiting Operational Efficiency of Cold Chain Piping Systems
