When personnel need to delay while falling, lifesaving hydraulic descent control device can be connected with fixed body (as desk, bed and the reliable fixed body of other bodies of wall) by ear seat 3-2 and the upper stationary rope 3-1 of its top, slow fall personnel and be reliably connected with human body with the human body connecting rope 3-13 of the rope 3-12 lower end on reel 3-5, or be reliably connected with the rescue braces being worn on human body, human body climbs out of from window, balcony etc., can realize steadily, delay and fall safely.When lifesaving hydraulic descent control device is slow while falling, it is upper that the weight of human body acts on the rope 3-12 of lifesaving hydraulic descent control device, produces corresponding turning moment on reel 3-5, and this moment is connected with the key 2-6 on hydraulic pump output shaft 2-5 by reel 3-5, passes to hydraulic pump output shaft 2-5.The inside of the inside of hydraulic pump 2 and one-way throttle valve group 1 is full of fluid in advance, and when lifesaving hydraulic descent control device is slow while falling, the hydraulic fluid port 2-2 from hydraulic pump of the fluid in hydraulic pump 2 flows out, and from hydraulic pump, hydraulic fluid port 2-1 flows back to.If being directly connected into and out of hydraulic fluid port of hydraulic pump 2, be the fluid of hydraulic pump 2 from hydraulic pump hydraulic fluid port 2-2 after flowing out directly from hydraulic pump hydraulic fluid port 2-1 flow back to, now hydraulic pump output shaft 2-5 cannot produce the turning moment that opposing torque balance human bady gravitational produces on reel 3-5, the output shaft 2-5 of reel 3-5 and hydraulic pump can accelerate rotation, cause human body to drop fast, send personnel casualty accidents.So, in the present invention, used one-way throttle valve group 1, guarantee that human body is steady, delay and fall safely.When lifesaving hydraulic descent control device is slow while falling, it is upper that the weight of human body acts on the rope 3-12 of lifesaving hydraulic descent control device, produces corresponding turning moment on reel 3-5, and this moment is connected with the key 2-6 of hydraulic pump 2 by reel 3-5, passes to the output shaft 2-5 of hydraulic pump 2.The inside of the inside of hydraulic pump 2 and one-way throttle valve group 1 is full of fluid in advance, when lifesaving hydraulic descent control device is slow while falling, the fluid of hydraulic pump 2 inside hydraulic fluid port 2-2 from hydraulic pump flows out, and by hydraulic fluid port 2-1 on hydraulic fluid port 1-1, hydraulic pump in hydraulic fluid port 1-4, valve group on hydraulic fluid port 1-7, throttle orifice 1-6, throttle orifice under hydraulic fluid port 1-13, throttle orifice under valve group, flow back to hydraulic pump 2.When fluid is flowed through throttle orifice 1-6, damping action due to throttle orifice 1-6, throttle orifice 1-6's is poor into and out of meeting mineralization pressure between hydraulic fluid port, this pressure differential acts in hydraulic pump 2 by lower hydraulic fluid port 2-2 and the upper hydraulic fluid port 2-1 of hydraulic pump, make hydraulic pump output shaft 2-5 form certain opposing torque, the turning moment that balance human bady gravitational produces on reel 3-5 in rotation.And, throttle orifice 1-6 enters, there is certain relation in the flow of the fluid that the pressure differential forming between oil-out and throttle orifice 1-6 pass through, that is to say, there is certain relation in the upper opposing torque forming of hydraulic pump output shaft 2-5 and the rotating speed of hydraulic pump output shaft 2-5, the opposing torque forming on the turning moment that human bady gravitational produces on reel 3-5 and hydraulic pump output shaft 2-5 is balance, the rotating speed of reel 3-5 is consistent with the rotating speed of hydraulic pump output shaft 2-5, so, the personnel's of certain body weight slow reduction of speed degree is certain, as long as throttle orifice 1-6 is reasonable in design, just the personnel's of different weight slow reduction of speed degree can be controlled in rational scope, guarantee that slow to fall personnel steady, safe land.
Utilize being connected of external handle and back shaft internal keyway 3-10, and with the driving back shaft 3-9 such as manual mode and the slow opposite direction direction rotation that falls, reel 3-5 is reverse rotation thereupon also, the rope of lifesaving hydraulic descent control device can progressively be packed up.When reel 3-5 counter-rotates, hydraulic pump output shaft 2-5 also counter-rotates, the fluid of hydraulic pump 2 inside hydraulic fluid port 2-1 from hydraulic pump flows out, through oil-in 1-1, valve group upper oil cavitie 1-2, the upper and lower communication channel 1-3 of valve group in valve group, overcome the active force of spring 1-10 to nonreturn valve core 1-5, nonreturn valve core 1-5 is pushed away to valve seat, and fluid by hydraulic fluid port 2-2 under hydraulic fluid port 1-13, hydraulic pump under valve group lower oil cavitie 1-8, valve group, flows back to hydraulic pump 2 again.While flowing through check valve etc. due to fluid, can not produce larger pressure differential, meanwhile, while rotating backward, the loading moment that has not existed human bady gravitational to produce reel 3-5, so, can be lighter when packing up lifesaving hydraulic descent control device rope 3-12.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, are not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
