As shown in Figure 1, spring energy-storage air-cut-off break 22 mainly comprises cylinder 20, compressed air brake cylinder 23 of dying, brute spring 19, push-down piston body 16, right end cap 21, sealing member 13, seal ring 18, support ring 17, and right end cap 21 sealing is arranged on the low order end of cylinder 20.Push-down piston body 16 is by the less pusher section 11 of anterior diameter, barrel portion two parts integrated molding that rear portion diameter is larger.
As shown in Figure 1, be respectively provided with a through hole 12,15 in cylinder 20 left end casing wall, cylinder barrel 7 right-hand member casing wall center, the pusher section 11 of the push-down piston body 16 of spring energy-storage air-cut-off break 22 can penetrate, pass two through hole 12,15.A sealing member 13 is respectively embedded at through hole 12, through hole 15 hole inwall circumferential direction, also can be according to circumstances, only a through hole 12 or 15 is embedded in a sealing member 13 wherein, sealing member 13 is high-performance sealed circle preferably, and, described cylinder barrel 7 seals with cylinder 20 by rubber seal 14 further, realizes the excellent sealing between pusher section 11 and two through hole 12,15.Push-down piston body 16 rear portion diameter compared with large cylinder part and the seal ring 18 that is provided with between cylinder 20 inwall for air seal, seal ring 18 is o RunddichtringO preferably, namely o RunddichtringO annular is nested in the rear portion of push-down piston body 16, also can be the mounting means of other existing sealing arrangements and sealing arrangement, offer an admission port 24 in the anterior upside of cylinder 20, thus form the compressed air brake cylinder 23 of dying of a relative closure in cylinder 20 front portion.
In addition, at the rear portion of described push-down piston body 16, the arranged on left and right sides of seal ring 18 is respectively arranged with a support ring 17.Support ring 17 is also flow ring, plays centering pilot effect, ensures that push-down piston body 16 does not depart from axis crank motion and strengthens sealing effectiveness better.
As shown in Figure 1, brute spring 19 is arranged at the rear portion that cylinder 20 is inner, correspondence is arranged on push-down piston body 16, the barrel portion side at described push-down piston body 16 rear portion carries the gaseous tension of compressed air brake cylinder 23 of dying, opposite side carrying brute spring 19 elastic thrust, push-down piston body 16 correspondence is arranged on the rear of the piston 2 of air-cylinder type brake cylinder 28, by promote piston 2, stop dish 1 forward (left) hold out against cage guide fast, realize seized.
In addition, as shown in Figure 1, to be provided with between dish 1 and cylinder barrel 7 that length is telescopic, cross section is wavy dust boot 30 stopping.Dust boot 30 one end is connected to dish 1 of stopping, and the other end is connected to the outer wall of cylinder barrel 7.
For ensureing that the utility model runs, some control cock are also had with the utility model is matching used, as shown in Figure 6: air-cut-off break hand control valve (HCV) 35 that be connected with air delivering pipeline, that control the start and stop of air-cut-off break device, and, air-cut-off break hand control valve (HCV) 35 also should be arranged in lift car, to facilitate manual control; Electromagnetic gas valve 36 that be connected with air delivering pipeline, that control the start and stop of each air-cylinder type brake cylinder pressurized air stream, is connected to the rapid release valve 37,38 for discharging each compressed air brake cylinder air pressure fast on air delivering pipeline.
During use, above the fixing railway carriage or compartment plate on the elevator car of the utility model a pair air-cylinder type brake cylinder 28 lateral symmetry, each air-cylinder type brake cylinder 28 is corresponding with the cage guide 33 or 34 of both sides respectively to be installed, each air-cylinder type brake cylinder 28 is fixedly connected with as a whole with lift car, the prior aries such as welding, bolt can be adopted to connect; According to actual needs such as elevator load, use fields, 1-2 can be set below the railway carriage or compartment base plate of lift car again to air-cylinder type brake cylinder 28.
Working process of the present utility model is: as Fig. 6, shown in Fig. 1, decline when hypervelocity occurs suddenly lift car or rise, in out of control at a slow speed, disconnected rope, during the situations such as improper start and stop, or when passenger enters, when going out terraced door, when elevator occurs fall instantaneously or suddenly rise, the secure induction device of elevator can send electric signal to electric control module, when electric control module accepts above-mentioned arbitrary signal, send instruction unpack electromagnetic gas valve 36, enter the compressed air brake cylinder 27 of each air-cylinder type brake cylinder 28 immediately through air delivering pipeline with the pressure gas of higher pressure, promote each piston 2 to extend to cage guide 33 direction of elevator both sides in very short time, to stop dish 1(or friction strengthening liner 31) hold out against cage guide 33 and be subject to strong friction force, realize above-mentioned in emergency circumstances safety, snap catch, maintainer's solution to be rescued in elevator after personnel, operation electromagnetic gas valve 36 related key or through rapid release valve 38, bleeder brake air chamber 27 internal gas pressure stream, air pressure disappears, brake off, elevator returns assigned address, etc. to be repaired.
As Fig. 6, shown in Fig. 1, when electric control system breaks down, electromagnetic gas valve 36 is malfunctioning, and air pressure because of failure vanishes or deficiency cause air-cylinder type brake cylinder 28 normally to work time, or because entering during normal use, go out elevator people many, when needing to rest in a certain floor for a long time, boarding personnel are left behind (closedown) air-cut-off break hand control valve (HCV) 35 in lift car, be off condition under electromagnetic gas valve 36 normality, air pressure stream ends, so, start each air-cut-off break device: brute spring 19 is when without gas compression, freely can uphold and advance rapidly push-down piston body 16 to travel forward, push-down piston body 16 promotes piston 2 and outwards extends, stop and coil 1(or friction strengthening liner 31) press cage guide 33, and the strong friction force in the surface being subject to cage guide 33, lift car is forced to be braked immediately, stop, to ensure boarding personnel life security.When needs brake off, boost (opening) air-cut-off break hand control valve (HCV) 35, compressed air stream conducting, as shown in Figure 1, air-cut-off break compressed air brake cylinder 23 is full of air pressure, and this air pressure promotes that push-down piston body 16 moves right, brute spring 19 also becomes original compressive state, piston 2 also elastic recoil to the right thereupon, stop and coil 1(or friction strengthening liner 31) depart from cage guide 33, brake release.
When lift car just in case when departing from cage guide 33, what the length of piston 2 can be made is longer, piston 2, stop dish 1(or friction strengthening liner 31) just can press wall surface around cage guide 33, elevator car safety also can be made to brake.
The figure of above-mentioned expression, explanation; be only several preferred embodiment of the present utility model; be not limit protection domain of the present utility model, all equivalent variations of doing according to the utility model claim or modification, be the utility model claim and contain.
