Road-railway combined transportation cold-chain translation butting device and system

Abstract

The invention discloses a road-railway combined transportation cold-chain translation butting device and system. The device comprises a chassis and walking wheels arranged at the four corners of the chassis, wherein a heat preservation butting box is arranged on the chassis; a driving mechanism is arranged between the heat preservation butting box and the chassis and is used for driving the walking wheels to drive the heat preservation butting box to move; elastic buffer devices are arranged at two ends of the heat preservation butting box; detection devices are arranged at the center positions of two ends of the chassis and are used for detecting and judging whether the heat preservation butting box is aligned with a railway heat preservation truck or a cold-chain truck; if the heat preservation butting box is not aligned with the railway heat preservation truck or the cold-chain truck, an offset is calculated, and a first control signal is generated according to the offset, and the walking wheels are driven to drive the heat preservation butting box to move, so as to allow the heat preservation butting box to be aligned with the railway heat preservation truck or the cold-chain truck; and when the heat preservation butting box is aligned with the railway heat preservation truck or the cold-chain truck, a second control signal is sent to control the elastic buffer devices to be inflated to realize sealed butting. The road-railway combined transportation cold-chain translation butting device can effectively avoid direct contact between frozen cargoes and air in a transferring process; and the intelligence and the stability of a frozen cargo transmission process and the parking precision of the railway heat preservation truck are improved.

Description

technical field [0001] The invention belongs to the technical field of railway cold chain logistics, and more specifically relates to a cold chain translation docking device and system for road-rail intermodal transport. Background technique [0002] With the rapid development of railway "door-to-door" logistics transportation, pure road transportation and pure railway transportation can no longer meet the needs of logistics express. With the development of the logistics and transportation industry, the joint transportation method of road and railway has been used to give full play to the respective advantages of road transportation and railway transportation. At present, various transportation solutions have been proposed at home and abroad, but they all have some shortcomings, such as high transportation costs and difficult implementation, so they are not suitable for promotion and use. [0003] For example, the multimodal transport in the United States has developed box-...

AI Technical Summary

Problems solved by technology

[0007] Aiming at at least one defect or improvement requirement of the prior art, the present invention provides a cold chain translational docking device and system for road-rail intermodal transport, the purpose of which is to solve the problem of air contact during the transfer of frozen goods from a railway insulated car to a cold chain freight car. Direct contact leads to a decrease in the quality of the goods, and the problem of low parking accuracy of the railway insulated car
