A rotary airlock station for vacuum pipeline transportation and a method for entering and exiting the pipeline midway

Abstract

Provided is a rotary air brake station for a vacuum pipeline traffic and a method of entering and exiting a pipeline halfway. 2-6 of brake tubes paralleling to a main pipeline are formed around the circumference of a vertical plane of the main pipeline, and one of the break tubes is coaxial with the main pipeline; the two ends of the break tubes are respectively connected with sealing slide plates a and sealing slide plates b; the outer side of the sealing slide plates a and the sealing slide plates b are fitted to the inside of flange plates a and flange plates b; and the outer side of flange plates a and flange plates b are connected with the main pipeline. The vacuum pipeline traffic method of entering and exiting the pipeline halfway comprises the following steps that vehicles enter into the break tubes; driving wheels drive a driving ring to rotate, and the driving ring drives the break tubes to rotate; the vacuum degree of the break tubes is reduced to be same as the main pipeline under an airtight state; the break tubes are continued to rotate; an inner barrel is fixed to the main pipeline in a positioned mode; the vehicles enter into the main pipeline; and when the vehicles evacuate, the reverse operation steps according to the above entering method are carried. According to the rotary air brake station for the vacuum pipeline traffic and the method of entering and exiting the pipeline halfway, the pipeline can be sealed and segregated separately, then the equipment, the vehicles and the personnel enter and exit nearby and quickly, and the problems of rescue and first-aid repair in the vacuum pipeline traffic are solved.

Description

technical field [0001] The invention belongs to the technical field of vacuum pipeline transportation, and in particular relates to a rotary airlock station for vacuum pipeline transportation and a method for entering and exiting the pipeline midway. Background technique [0002] Vacuum pipeline transportation is a future transportation system that will be constructed and implemented. It is suitable for long-distance long-distance transportation. The length of the line is generally greater than 1,000km, and some may be greater than 10,000km. The average station spacing is relatively large, usually greater than 100km. During operation, a certain vacuum is drawn in the pipeline, and the pipeline is in a strictly closed and airtight state. [0003] In order to inspect and repair the internal facilities of the pipeline, workers need to enter and exit the pipeline. If you enter and exit from the station and are too far away from the equipment failure point, it will delay time an...
