Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment and Detailed description of the invention, the preferred embodiment that the present invention is further explained.
Embodiment
Fig. 1-Fig. 6 is please referred to, the present invention provides the elevator brake-releasing gear with emergency pooling feature, and structure includes magnetic force
Device 1, brake bar 2, brake arm 3, brake scotch 4, meet an urgent need structure 5, magnetic apparatus chassis 6, braked wheel 7, pacify on the magnetic apparatus chassis 6
Equipped with magnetic apparatus 1, the horizontal left and right ends of the magnetic apparatus chassis 6 are all equipped with brake arm 3, and 3 middle of brake arm is equipped with
Brake scotch 4, the brake scotch 4 and 3 screw of brake arm are fixed, and braked wheel 7 is equipped between two brake arms 3, and the brake bar 2 is set
In the outside of 3 relative magnetic device 1 of brake arm, the 6 inner horizontal both ends of magnetic apparatus chassis are all equipped with emergency structure 5, described to answer
The 6 activity cooperation of anxious structure 5 and magnetic apparatus chassis.
The emergency structure 5 is equipped with cable placement pipe 51, electromagnet 52, brute spring 53, slide bar 54, slideway 55, braking
Plate 57, road junction 58 form, and the road junction 58 is opened in 6 bottom both ends of magnetic apparatus chassis, and 58 inner tip of road junction is embedded with electromagnetism
Iron 52,52 top of electromagnet are equipped with cable and dispose pipe 51, cable placement pipe 51 after magnetic apparatus chassis 6 it is exposed
In air, the electromagnet 52 is long to be wider than cable placement 51 diameter of pipe, and 6 inner wall of magnetic apparatus chassis of 58 two sides of road junction is all
It is provided with slideway 55, the 57 top two sides level of brake plate is welded with slide bar 54, the slide bar 54 and slideway 55 and is matched using sliding
It closes, the slide bar 54 and slideway 55 are equipped with brute spring 53, the brute spring about 53 two between that end of electromagnet 52
End is separately fixed on 55 inner tip of slideway and slide bar 54.
52 bottom end of electromagnet is equipped with steel disc 52a, and the steel disc 52a is locked on magnetic apparatus chassis 6 by screw, benefit
It uses steel disc 52a as bottom support, avoids electromagnet 52 from loosening in multiple braking, brake plate 57 can not be raised.
The width of the steel disc 52a is less than the half of electromagnet 52, avoids completely obscured electromagnet 52, electromagnet 52
It can not be bonded with the absorption completely of brake plate 57.
End of the brake plate 57 far from magnetic apparatus 1 is arcuation, is bonded completely with braked wheel 7, and this side surface is equipped with
More than two circular arc protrusion 57a, the circular arc protrusion 57a and brake plate 57 are integrated, and increase friction, avoid braking
Opposite sliding occurs in high process for plate 57 and braked wheel 7, can not brake braked wheel 7.
6 inner walls of magnetic apparatus chassis, that is, 58 bottom end of road junction positioned at 55 lower section of slideway is equipped with lever 56, supports as bottom beam
Magnetic apparatus chassis 6, avoids it from deforming, and 58 bottom diameter of road junction reduces, and brake plate 57 slides up and down limited, can not glide.
When elevator remains static, 1 electric current of magnetic apparatus passes through, at this moment because of unattractive between electromagnetic core, braking
Watts 4, brake arm 3 holds braked wheel 7 tightly under the effect of 2 pressure of brake bar, guarantees that motor does not rotate, and brake plate 57 is in strength
Under spring 53 acts on, decline 57 bottom end of brake plate and braked wheel 7 completely and be bonded completely, increase the frictional force with braked wheel 7, when draging
Draw motor to be powered the moment rotated, the coil of magnetic apparatus 1 is electrified stream simultaneously, and electromagnetic core magnetizes rapidly actuation, drives system
Swing arm 3 makes its brake bar 2 by active force, and brake scotch 4 is opened, completely disengaged with braked wheel 7, while the magnetization generation of electromagnet 52
Magnetic force is greater than the elastic force of brute spring 53, and brake plate 57 is gone completely under magneticaction toward 55 top of slideway cunning, compresses strength bullet
53, elevator is run；When stopping needed for lift car arrival, hoisting motor power loss, electromagnet 52, magnetic apparatus 1 are also same
When power loss, under the action of brake bar 2 brake arm 3 reset, the reaction speed that relative brake watt 4 again embraces braked wheel 7, nothing
The fixed brake plate 57 of pin shaft sinks rapidly in slideway 55 under the effect of brute spring 53, rubs with braked wheel 7, therefore
In braked wheel 7 because brake plate 57 pops up clamp braked wheel 7 immediately when passivation reaction is blunt, slow down the rotation speed of braked wheel 7
Degree reduces the revolving speed of elevator motor, slow down the speed of elevator decline, avoid personnel safety crisis, reacts in braked wheel 7
When rapid, its friction also can increase, shorten braking time, improve safety coefficient.
Problems solved by the invention is by being used for a long time, and the pin shaft of brake is because cross machine oil, meeting without upper for a long time
Passivation, it is slow in reacting, brake scotch can not be allowed to be bonded braked wheel after power-off immediately, realize that braking stops immediately, also will continue to,
If the number of plies where elevator is excessively high, excessive height acceleration is more as large as 12 layers, even if only three people in elevator, will also result in personnel's wound
Evil, the present invention are combined with each other by above-mentioned component, and the present invention passes through emergency structure 5, magnetic apparatus 1, brake bar 2, brake arm 3 etc.
Under common cooperation, in braked wheel 7 because brake plate 57 pops up rub with braked wheel 7 immediately, slows down when passivation reaction is blunt
The velocity of rotation of braked wheel 7 reduces the revolving speed of elevator motor, slow down the speed of elevator decline, avoids personnel safety danger
Machine also can increase its friction when braked wheel 7 is swift in response, and shorten braking time, improve safety coefficient.
