Abstract
The invention relates to a multi-stage deceleration parachute for deceleration of a high-speed train and belongs to the technical field of trains. The invention provides a multi-stage deceleration parachute scheme according to a closed environment on the periphery of a running track of the high-speed train; by opening a plurality of deceleration parachutes connected in series, the defect that the area of each of the deceleration parachutes is limited can be effectively overcome, and further, the train can obtain effective pneumatic braking force. The invention realizes the design purpose in such a manner that a plurality of deceleration parachute pack placing tables capable of being arranged side by side and sliding along the track are arranged at the bottom of a carriage at the tail part of the train and are connected together by using ropes; when braking is needed, the first deceleration parachute pack placing table is opened after being pulled out by the small parachute, and then other deceleration parachute pack placing tables are pulled out and opened in sequence, so that a deceleration parachute array is formed to jointly generate the deceleration braking force. The lower part of each of the opened deceleration parachutes is fixed on the corresponding parachute pack placing table, so that the casual swinging of the deceleration parachutes cannot occur.
Description
The present invention relates to a kind of bullet train aerodynamic decelerator umbrella scheme, belong to train technical field.
The aerodynamic decelerator device that bullet train uses at present has the flexible deceleration that expandable platy structure flap and afterbody are released
Umbrella.Rigid flap is limited by car body, and area can not be too big, and therefore braking effect is limited.Owing to bullet train uses electricity
Try hard to recommend into, have electric pole on the track both sides of train driving, its overhung is disposed with cable, and therefore the area of drag parachute is not
Can be excessive, seriously limit the deceleration usefulness of drag parachute.
The present invention proposes a kind of multi-stage speed-reducing umbrella scheme according to the enclosed environment around current bullet train running rail, passes through
Open multiple be serially connected, towing drag parachute of being controlled of track, existing drag parachute scheme can be effectively shielded from and deposit
Umbrella cover amass by the feature that limited of towing space, become several times to increase Parachute areas, and then train can be made to utilize deceleration
Umbrella obtains effective aerobraking power.
The present invention is realized in purpose of design；Arrange in the bottom of last vehicle of train railway carriage several located side by side, can be along rail
The deceleration pack mounting table that road slides, links up with rope between them, and when needs are braked, first pack platform is first used
Little pull-out umbrella pulls open, and other pack platforms are pulled out by umbrella above the most successively and open subsequently, thus form one and subtract
It is the umbrella battle array of several times of original single drag parachute that speed umbrella cover amasss, and common produces retarding braking power.The bottom of all drag parachutes is the most fixing
On respective pack mounting table, such drag parachute would not swing with the wind, and Parachute area can be made as close possible to maximum.
Compared with the drag parachute of hard flap and a limited area, multi-stage speed-reducing umbrella scheme can not increase railway carriage complexity
Realize the effective brake of bullet train in the case of property, braking distance can be shortened more than 70%.
Accompanying drawing is bullet train deceleration multi-stage speed-reducing umbrella schematic diagram.
Referring to the drawings；Package unit is made up of several drag parachutes 1 and several pack placement/canopy fixed station 2 two large divisions.The
The umbrella rope 3 of one drag parachute couples ON TRAINS, after the umbrella rope 4 of drag parachute be then respectively coupled to pack above place/
On canopy fixed station.All canopies middle 5 are fixed on the pack placement/canopy fixed station of oneself, for preventing both sides below
Canopy towing grazing ground, is provided with sled 6 several below drag parachute.All pack placement/canopy fixed stations do not use
Time be placed on the clamping device bottom afterbody train, put down during use, table-board bracket, on rail, has card-like to tie below two ends
Structure just inner side to rail, for being pitched by railway road, after this card-like structure clamping rail, its thickness and train wheel limit
The same size of edge.During use clamping device bottom train all of pack is placed/canopy fixed station all puts down so that it is
Automatically snapping between two rails, the pull-out umbrella 7 on last drag parachute ejects subsequently, is pulled open by this umbrella, and this umbrella is opened
Umbrella above is pulled open successively by Cheng Zhongzai by corresponding rope.For controlling braking overload, the distance between each umbrella can use corresponding machine
Structure controls, and has just started little, has the most gradually amplified, and maximum can be more than more than 50 meters.
Claims (1)
1. a multi-stage speed-reducing umbrella is used in bullet train deceleration, it is characterized in that the middle of all drag parachutes couples respectively
