Abstract
The invention discloses a rope-breaking preventing damp slow-down elevator which comprises a cage, a guide rail, a hoisting rope, a traction sheave, a traction frame and a traction motor; the rope-breaking preventing damp slow-down elevator further comprises a damp slow-down device and an electric control system thereof; the damp slow-down device comprises a pulley rope, a top pulley, a top pulley yoke, a clutch, a damping device, a bottom pulley and a bottom pulley frame; the pulley rope is respectively twisted on the top pulley and the bottom pulley up and down, two ends of the pulley rope are respectively fixed at the upper end and the lower end of the cage, and the clutch is arranged between the damping device and the top pulley; the electric control system comprises a pressure sensor and a control device; and the pressure sensor is arranged below the traction frame and is connected with the control device through a wire, and the control device can control the separation and junction states of the clutch. The rope-breaking preventing damp slow-down elevator has the following advantages: when a traction rope is broken, the cage can slow down at the bottom, and persons in the cage can successfully escape, so that the safety performance is improved greatly; and furthermore, the rope-breaking preventing damp slow-down elevator can be served as elevators or lifting equipment of various buildings and mines, and can be applied to the improvement of the existing elevators.
Description
Technical field
The invention belongs to a kind of elevator, relate in particular to a kind of elevator with the anti-break rope safety device.
Background technology
The lifting machinery such as cage of using in the elevator that building is used, the mine generally all comprise car, hoist ropes, traction sheave, traction frame, traction motor; these lifting machinery have the safety guard that prevents that hoist ropes from disconnecting; the safety guard major part of elevator all is to adopt the safety tongs of American E.G. Otis invention; safety tongs is under the manipulation of velocity limiter; after the very serious fault such as hypervelocity, disconnected rope appears in elevator, with the urgent stop of car and be clamped in a kind of safety device on the guide rail.The patent No. is 02214343.2 Chinese invention patent for another example, a kind of elevator, derrick Anti-breaking rope device are also disclosed, simultaneously by at cage hook being installed, a kind of carriage is installed on the track, when promoting the hoist ropes fracture, hook on the cage can be hung in orbit the carriage at once, is parked in the air, can prevent falling of cage.The method that above-mentioned these safety guards adopt all is same thinking; elevator or cage can block in orbit when the hoist ropes fracture exactly; rest on aerial; but the mode of this hovering also exists some defectives and deficiency; it has brought huge trouble to rescue operation; the people is trapped in the aerial elevator for a long time can't get out; there is secondary potential safety hazard; in addition; these anti-break rope elevators all need cage guide is improved; increase corresponding member, also have the higher problem of cost.
Summary of the invention
The problem to be solved in the present invention provide a kind of when hoist ropes disconnects car can slowly drop to the elevator of the bottom.
In order to address the above problem, the technical solution used in the present invention is: anti-break rope damp slow falling elevator, comprise car, guide rail, hoist ropes, traction sheave, traction frame, traction motor, it is characterized in that: also comprise damp slow falling device and electric-control system thereof, described damp slow falling device comprises chain wheel rope, top pulley, top pulley yoke, power-transfer clutch, damping arrangement, bottom pulley and bottom pulley yoke; The top pulley is installed on the pulley yoke of top, the bottom pulley is installed on the pulley yoke of bottom, chain wheel rope is wrapped in respectively up and down on top pulley and the bottom pulley, a upper end that is fixed on car of chain wheel rope, another fag end is fixed on the lower end of car, and the chain wheel rope car connects together and formed a closed-loop structure; Be provided with power-transfer clutch between damping arrangement and the top pulley; Described electric-control system comprises pressure sensor and control setup; Pressure sensor is installed in below the traction frame, and pressure sensor links to each other with control setup by wire, and can provide pressure signal for control setup, but the separation of control setup control clutch and bonding state.
When elevator of the present invention normally uses, power-transfer clutch is in released state, traction motor rotates by the traction sheave that drives on the traction frame, make hoist ropes drive car and move up and down at guide rail, the chain wheel rope that is wrapped in simultaneously on top pulley and the bottom pulley can together move with it because being connected with car.When hoist ropes is given birth to fracture, traction sheave no longer is subject to the pressure from hoist ropes, being installed in the pressure that the pressure sensor below the traction frame is subject to diminishes suddenly, pressure sensor can pass out signal to control setup, makes the power-transfer clutch between its control damping arrangement and the top pulley become engagement state by released state originally.So when car began to drop, it can be subject to the damping from damp slow falling device, descending speed is tending towards at the uniform velocity gradually, then realize slow falling, until safety drops to the bottom.
The present invention's advantage compared with prior art is: when hoist ropes disconnects, car can not be stuck in the interlayer of aerial floor, can delay and drop to the bottom, the people of the inside can escape smoothly, elimination the difficulty of air rescue, safety performance significantly improves, and has simultaneously also reduced corresponding cost owing to need not transform guide rail, the present invention can make elevator, the jacking equipment of all kinds of buildings and mine, also can be applicable to the improvement of existing elevator.
