Abstract
The invention relates to a magnetic eddy-current damping safe elevatorwhich comprises an electric motor, a speed reducer, a band-type brake, a car, a balancing weight, a steel wire rope fixedly connected with the balancing weight and an elevator shaft, wherein copper plates are arranged on the periphery outer walls and the bottom outer surface of the car fixedly connected with the steel wire rope; permanent magnet magnetic strips are arranged on the periphery inner walls of the bottom surface of a pit; permanent magnetclamp plates are arranged on the surface of the inner wall of the elevator, copper plate speed reducing wings which protrude and extend outwards are arranged on the outer wall of the car and located in a longitudinal space among the permanent magnetclamp plates. The magnetic eddy-current damping safe elevator is simple in structure and convenient to mount and use, when the tractionsteel wire rope breaks accidently, the car can be effectively prevented from colliding the ground fiercely, casualties in the car and property loss are avoided.
Description
Technical field the present invention relates to a kind of elevator car safety, is especially applicable to the magnetic force eddy current damping emergency staircase of vertical lift.
Background technology elevator is a kind ofly with electrical motor outputting power, to carry out jacking equipment, and car is realized upright position by steel rope and converted under the traction of electrical motor, realizes the object of passenger-carrying or goods.Therefore in use inevitably because long-term use caused steel rope fatigue or wearing and tearing, once as occurred the unexpected crack conditions of steel rope, will the personal safety of passenger in car be constituted a threat to and be caused any property loss.
Summary of the invention the object of this invention is to provide a kind of steel rope and surprisingly ruptures car while falling, and can guarantee personnel's personal safety in car and prevent the magnetic force eddy current damping emergency staircase of property damage.
For achieving the above object, magnetic force eddy current damping emergency staircase of the present invention, by electrical motor, retarder, band-type brake, car, clump weight, form with affixed steel rope and the elevator of clump weight, wherein be provided with copper coin with affixed car surrounding outer wall and the bottom outer surface of steel rope, pit surrounding inwall and bottom surface are provided with permanent-magnet magnetic lath, elevator inner wall surface is provided with permanent magnetism clamping plate, car outer wall is provided with outstanding overhanging copper coin deceleration wing, in the longitudinal space of this deceleration wing between permanent magnetism clamping plate.
Adopt after said structure, faster according to inducing current magnetic field medium velocity, area of contact is larger, the larger principle of work of reverse resistance producing, the permanent magnetism clamping plate that are arranged on elevator inner wall surface when elevator when low speed normally moves only produce faint magnetic force eddy current, and to elevator, normal operation does not have any impact.When steel rope surprisingly rupture elevator car out of control during in high-speed falling state permanent magnetism clamping plate interact with the outstanding overhanging copper coin deceleration wing and the car surrounding outer wall copper coin that are arranged on car outer wall, produce powerful magnetic force vortex field, stop cab acceleration descending.Simultaneously the permanent-magnet magnetic lath in pit surrounding inwall and lower surface can produce decline resistance with car surrounding outer wall and the interaction of bottom outer surface copper coin to car.
As a further improvement on the present invention, the permanent magnetism clamping plate that elevator inner wall surface is provided with are that the symmetrical overhanging copper coin deceleration wing corresponding with permanent magnetism clamping plate and that be arranged on cab outer wall of biserial is also biserial symmetry.
Description of drawings 1 is the integral structure schematic diagram of magnetic force eddy current damping emergency staircase of the present invention.
The specific embodiment is further described the present invention below in conjunction with accompanying drawing,
As shown in Figure 1, magnetic force eddy current damping emergency staircase of the present invention, by electrical motor 1, retarder 2, band-type brake 3, car 4, clump weight 5, form with affixed steel rope 8 and the elevator of clump weight, wherein be equipped with copper coin 6 with affixed car surrounding outer wall and the bottom outer surface of steel rope, pit surrounding inwall and bottom surface are fixed with permanent-magnet magnetic lath 7, elevator inner wall surface is fixed with permanent magnetism clamping plate 10, car outer wall is welded with outstanding overhanging copper coin deceleration wing 9, in the longitudinal space of this deceleration wing between permanent magnetism clamping plate.The permanent magnetism clamping plate that elevator inner wall surface is provided with are that biserial is symmetrical, and overhanging copper coin deceleration wing corresponding with permanent magnetism clamping plate and that be arranged on cab outer wall is also biserial symmetry.
In actual use, faster according to inducing current magnetic field medium velocity, area of contact is larger, the larger principle of work of reverse resistance producing, the permanent magnetism clamping plate that are arranged on elevator inner wall surface when elevator when low speed normally moves only produce faint magnetic force eddy current, and to elevator, normal operation does not have any impact.When steel rope surprisingly rupture elevator car out of control during in high-speed falling state permanent magnetism clamping plate interact with the outstanding overhanging copper coin deceleration wing and the car surrounding outer wall copper coin that are arranged on car outer wall, produce powerful magnetic force vortex field, stop cab acceleration descending.Simultaneously the permanent-magnet magnetic lath in pit surrounding inwall and lower surface interacts and can produce to car the damping buffering application force that makes progress with car surrounding outer wall and bottom outer surface copper coin, damping stroke length can reach 2-3 rice, effectively reduce the impact of stall car to ground, make its stable landing in pit bottom surface, avoid causing casualties and property damage.
It is simple in structure, easy to install that the present invention has, and when haulage cable surprisingly ruptures, can effectively prevent car and ground sharp impacts, avoids the safety device of the interior personal casualty of car and property damage.
