Workshop connecting structure with upper capstan and lower capstan and vacuum pipeline train with workshop connecting structure

Abstract

The invention discloses a workshop connecting structure with an upper capstan and a lower capstan and a vacuum pipeline train with the workshop connecting structure. The workshop connecting structure comprises an upper connecting point and a lower connecting point; the upper connecting point and the lower connecting point both adopt a hinged connection mode, the upper connecting point becomes an upper capstan, and the lower connecting point is called a lower capstan; the upper capstan comprises an outer column disc, an inner column disc and a first elastic element; the lower capstan comprises a concave disc, a convex disc and a second elastic element; by means of the structure, the problem that longitudinal loads between the mutually-communicated carriages are unbalanced due to the internal and external pressure difference of the train is effectively solved, the hinged connection mode between the carriages is achieved, and the safety of the train during high-speed running is improved; the connection strength between the carriages is increased, and the safety when a fault occurs is greatly improved; the integrity of the train is improved, the vibration amplitude is reduced, and the stability and comfort of the train are improved.

Description

technical field [0001] The invention belongs to a vacuum pipeline transportation system, in particular to a workshop connection structure with upper and lower hinge plates and a vacuum pipeline train comprising the workshop connection structure. Background technique [0002] The main resistance of high-speed rail trains running in the dense atmosphere on the earth's surface is air resistance, which limits the speed increase and causes huge energy consumption. Theoretically, in order to increase the speed of operation and reduce the energy consumption of operation, the track of the train can be placed in the pipeline, and the pipeline can be evacuated, and the train can be run in the vacuum pipeline, which is called "vacuum pipeline train". [0003] From the perspective of engineering practice, the so-called vacuum pipeline is not a complete vacuum state. There is still extremely low pressure air in the pipeline. within minutes because of lack of oxygen to death, so the cabi...
