Background technology
Time have the message that used during elevator falling is hurted sb.'s feelings to be seen in media. Skyscraper is built more and more, and elevator is requisite fortune every dayThe instrument of carrying, for the producer of skyscraper, the situation of the quality of special concern elevator and elevator annual test. Although elevator goes outThing few, once and meet accident, life-and-death matter, the light limbs disability of also wanting. The elevator of existing vertical lift, its safetyDevice is mostly arranged on the outside of elevator, such as the bottom of elevator box, or on the sidewall of elevator box, for standing inThe personnel of elevator the inside, all safety devices be cannot see, be can not touch, not sure, take at ordinary times elevator heart totalThere is a kind of fear, be just afraid of that elevator meets accident. Even elevator door is not opened or elevator is parked in suddenly the position between two floorsPut and motionless, also can cause a burst of fear, not in time, elevator can be detained for a long time accident treatment sometimes, makes elevatorThe people of the inside is at a loss. If have child to cry and scream or old man's faintness, can aggravate panic spreading.
Summary of the invention
The object of the invention is the problem existing in order to solve above-mentioned prior art. And then provide a kind of vertical lift elevatorSafety device.
The object of the invention is to be achieved through the following technical solutions:
A safety device for vertical lift elevator, comprising: bottom safety device, described bottom safety device comprises twoAssembly pulley, damping spring, pedal, ratchet, rope sheave, handgrip, very heavy, very heavy axle, spring leaf and crank, described twoIndividual assembly pulley is symmetrical arranged, and each assembly pulley comprises the first pulley, the second pulley, the 3rd pulley, the 4th pulley, the 5thPulley and steel wire rope, the lower end of described damping spring is connected with elevator base plate, and the upper end of damping spring is connected with pedalConnect, the first pulley is fixed on the side on elevator base plate, and the second pulley and the 4th pulley are fixed on another on elevator base plateSide, the 3rd pulley is fixed on the bottom of the pedal between the second pulley and the 4th pulley, and the 5th pulley is fixed on elevator rear cabinetThe rear portion of plate, ratchet is arranged on the front portion of elevator rearing-box plate, and rope sheave is arranged on the rear portion of elevator rearing-box plate, ratchet and rope sheaveCoaxial connection, one end of steel wire rope is fixedly connected with the pedal on the first pulley top, and the other end of steel wire rope is sliding via firstWheel, the second pulley, the 3rd pulley, the 4th pulley and the 5th pulley are wrapped on rope sheave, and very heavy axle is fixed on elevator rear cabinetThe front portion of plate, very heavy one end and very heavy axle are rotationally connected, the very heavy other end matches with ratchet, the lower end of handgrip withVery heavy stage casing is connected, and one end of spring leaf is fixed on the front portion of elevator rearing-box plate, and the other end of spring leaf acts on handUpper, ratchet is provided with square hole, and the square toes on crank match with the square hole on ratchet.
The safety device of vertical lift elevator also comprises top safety device, and described top safety device comprises several elasticityLift, described each elasticity lift comprises two box bodys, axle, rubber sleeve, two box body seateds and steel disc bulletSpring, described two box body seateds are symmetrical arranged, and the upper end of box body seated is fixedly connected with the top of the upper cover plate of elevator, boxThe lower end of body seated is fixedly connected with box body, between two box bodys, is provided with axle, and box body is provided with opening, one of steel sheet springEnd is arranged on an axle in box body, and the other end of steel sheet spring is arranged on the axle in another box body, steel sheet springStage casing be provided with rubber sleeve.
Bottom of the present invention safety device is arranged on vertical lift elevator, and state is at ordinary times: shake clockwise with crankRatchet is wound around steel wire rope on rope sheave, due to the first pulley, the second pulley, the 3rd pulley, the 4th pulley and the 5thThe acting in conjunction of pulley, makes pedal to lower compression damping spring, damping spring can be compressed to the limit. Like this goodPlace reduces space hold, and people steps down in the existence of imperceptible spring on pedal, has steady and sure sensation. Ratchet is very heavyUnder effect, can not rotate, pedal can not be upspring. In the time that elevator runs into emergency case and drops fast, the occupant of elevator the inside is fastSpeed is moved handgrip, makes the very heavy ratchet leaving on ratchet, and damping spring discharges rapidly elasticity rises pedal, gives in elevatorBuffering after one of the occupant of face is born, is used for less injures and deaths.
Top safety device can with bottom safety device use, damping spring discharge rapidly elasticity make pedal rise time,The occupant of elevator the inside catches rapidly rubber sleeve, even both arms can be hung on rubber sleeve, make great efforts health to hang, withReduce elevator inertia when born, can further reduce injures and deaths.
The present invention is simple in structure, easy for installation, and using method is simple, can use by the demonstration of twice. The present inventionBe arranged on there, elevator occupant is visible, tangible, just as the life vest of cabin the inside, is an ornament at ordinary times,Once there is used during elevator falling accident, just can greatly alleviate the possibility of disability, in order to protect elevator member's life peaceEntirely.
