Description
Technical field
The utility model relates to bag umbrella mechanomotive force system regions, specifically, relates to a kind of resistance pack umbrella mechanomotive force system.
Background technique
Fighter plane is in flight training, and the main resistance parachute that adopts shortens the distance of alightinging run, and along with the increasing of the strong speed of flying unit's training, for meeting airplane training requirement, guarantees Flight Safety, has higher requirement to the wrapping quality of resistance parachute and efficiency.
Existing resistance pack umbrella mode is mainly artificial bag umbrella mode and cold air bag umbrella mode.The method of artificial bag umbrella mode is: by resistance parachute from level to level put into umbrella cylinder, put simultaneously one deck umbrella will with specialist tools tamping once.The major defect of artificial bag umbrella is: 1, inefficiency, and the bag umbrella time is long, and intensity of workers is large, and is difficult to the needs meeting flight support, and often wrap up a resistance parachute and need 3 to 4 people, 10 ~ 15 minutes average used times completed; 2, bag umbrella is of poor quality, and easily causes the damage of resistance parachute, shortens the working life of resistance parachute.
The method of cold air bag umbrella mode is: using cold air as power, and resistance parachute, as the active force of ACTUATOR, is pressed into umbrella cylinder to complete the operation of bag umbrella by cold air cylinder.The major defect of cold air bag umbrella is: 1, ensure that department is many, the manpower and materials dropped into are large, because cold air can not recycle, cold air is adopted to be power wrapping resistance parachute, the pressurized air that each need of work is a large amount of, and the producing of cold air and air bottle, transport and need to drop into larger manpower and materials and could realize; 2, wrapping quality is low, job security is poor, adopt pressurized air as motivational drive cold air ACTUATOR wrapping resistance parachute, because pressurized air itself has compressibility, cause ACTUATOR job insecurity in movement process, action is slightly violent, easily there is tear resistance umbrella or wrap up not tight phenomenon, even may injure personnel; 3, inefficiency, and intensity of workers is large, slightly violent for slowing down cold air, existing cold air bag umbrella device is all provided with flow controller, and have a strong impact on the movement velocity of pressure umbrella ACTUATOR, working efficiency greatly reduces, and the preparatory work of bag umbrella personnel is more, labor intensity is larger; 4, cold air utilization ratio is low, and gas cylinder demand is large, and pressure umbrella ACTUATOR often stretches once, air bottle pressure will reduce once, when being reduced to a certain degree, needs again filling cold air can continue to use, cause cold air to utilize not thorough, air bottle residual pressure is comparatively large, large to the demand of gas cylinder.
China Patent No. CN204096175 discloses a kind of resistance parachute wrapping machine, the drive system of wrapping machine is made up of source of the gas, reduction valve, selector valve, bleed pressure table, flow control valve and pipeline, during drive system work, bleed pressure is adjusted to the air pressure needed for work by reduction valve, the lifting being arranged on platen on cylinder is controlled, by the size of Flow-rate adjustment valve regulation air-flow and then the movement velocity of control platen by selector valve.As can be seen here, what this wrapping machine adopted is pneumatic-typed resistance parachute wrapping machine, owing to adopting pressurized gas itself, there is compressibility, cause platen job insecurity in movement process, and use pressurized gas mode to need manpower and materials and the financial resources of at substantial, cause its bag umbrella efficiency and bag umbrella quality can not meet the requirement of existing airplane training and flight safety.
