Description
Technical field
This utility model relates to elevators field, particularly to a kind of buffer of elevator.
Background technology
Buffer of elevator mainly has two kinds of forms: spring buffer and hydraulic buffer.Spring buffer refers to
Being spring buffer, the helical spring that critical piece is made up of circular or square wire, volute spring seldom makes
With.Spring buffer is only used for the normal speed elevator less than 1.0m/s.Hydraulic buffer is applicable to any speed
Elevator, when being loaded with the car free-falling of rated load, and the impact velocity taken during with design buffer is applied to buffering
Time on device, average retardation rate not should be greater than 1g, and deceleration not should be greater than 0.04S more than more than the 2.5g time.
In recent years, along with popularizing of elevator, elevator safety accident the most gradually increases, and its safeguard protection seems more important.
Existing buffer can not preferably meet people's demand to elevator safety.
Utility model content
This utility model purpose is solution the deficiencies in the prior art, it is provided that a kind of deceleration is steady, in stopping safety, impacting
Little buffer of elevator.
This utility model solves problem and the technical scheme is that a kind of buffer of elevator, including guide rail, described guide rail
In T shape, this guide rail is fixed with the sensing metal derby in linear array, the both sides of described guide rail are provided with chute, described
Being provided with first of guide rail leads boots with Baltimore groove, and this is led boots and is provided with roller, and described roller rolls in the chute of guide rail,
Described boots of leading are provided with support, lead and are provided with the iron core being fixed on support inside boots, and the outer ring of this iron core is wound with excitation wire
Circle, described leading is additionally provided with wire support, is installed with the wire being connected with elevator emergency stand-by power supply in this wire support on boots.
Further setting as such scheme: described guide rail scribbles high temp glass fibre with leading boots Baltimore groove inner surface
Dimension.
Further setting as such scheme: described magnet exciting coil is that the figure of eight is wrapped on iron core.
Further setting as such scheme: the described both sides leading boots are respectively provided with a fan.
The beneficial effects of the utility model are: guide rail is in " T " font, and rigid is high, reliability is high, can bear elevator and surpass
The power of stop elevator during speed accident.Guide rail and lead boots Baltimore groove inner surface and scribble high-temperature glass fibre, has high temperature resistant and insulation
Effect, prevent heat that eddy current produces from guide rail and leading the rigid of boots and produce impact.This buffer of elevator is by ferrum
Core and the logical suitable electric current of magnet exciting coil, under the effect of sensing metal derby, elevator just steadily can slow down under runaway condition,
The limiter of speed moment monitors the operation conditions of elevator, once notes abnormalities, and will transmit signals to control centre, to start this dress
Put, speed when energy continuous effective reduction elevator is out of control and energy, make elevator safety only stay, ensure human life's property in car
Safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: guide rail 1, chute 11, sensing metal derby 2, lead boots 3, wire support 31, roller 4, support 5, iron core 6, excitation
Coil 7, wire 8, fan 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
This utility model one buffer of elevator, including guide rail 1, described guide rail 1 is in T shape, and this guide rail 1 is fixed with
Sensing metal derby 2 in linear array, the both sides of described guide rail 1 are provided with chute 11, described guide rail 1 be provided with first with
Baltimore groove lead boots 3, this is led boots 3 and is provided with roller 4, and described roller 4 rolls in the chute 11 of guide rail 1, and described leads boots 3
Being provided with support 5, lead boots 3 inside and be provided with the iron core 6 being fixed on support 5, the outer ring of this iron core 6 is wound with magnet exciting coil 7, institute
Leading of stating is additionally provided with wire support 31 on boots 3, be installed with the wire 8 being connected with elevator emergency stand-by power supply in this wire support 31.
Described guide rail 1 and lead boots 3 Baltimore groove inner surface and scribble high-temperature glass fibre.
Described magnet exciting coil 7 is wrapped on iron core 6 in the figure of eight.
The described both sides leading boots 3 are respectively provided with a fan 9.
Elevator can be limited the freedom of movement of car and counterweight in running by guidance system, makes car and counterweight
Move up and down only along respective track, horizontal swing and vibration do not occur.In guidance system, in hoistway, it is provided with elevator
The guide rail 1 run, guide rail 1 is fixedly connected on well enclosure by rail brackets 5.Guide rail 1 is in " T " font, and rigid is high, reliable
Property high, the power of stop elevator when can bear elevator overspeed accident.Lead boots 3 corresponding with guide rail 1, and load onto on cage guide 1
Sensing metal derby 2, simultaneously at the built-in upper core of Baltimore groove 6 of elevator guide shoe 3, the outer ring of iron core 6 is wound with encouraging in the figure of eight
Magnetic coil 7, the combination of iron core 6 and magnet exciting coil 7 forms an electric magnet.Guide rail 1 and lead boots 3 Baltimore groove inner surface and scribble high temperature
Glass fibre, has the high temperature resistant and effect of insulation, and guide rail 1 and the rigid leading boots 3 are produced by the heat preventing eddy current from producing
Raw impact.
When elevator has an accident hypervelocity, limiter of speed sends command adapted thereto, triggers safety tongs and buffer.Strong at safety tongs
Stop stop car invalid in the case of, again trigger buffer be energized and start working.While elevator declines, iron core 6 He
The electric magnet of magnet exciting coil 7 composition works in time and sends the most powerful magnetic field, and the sensing metal derby 2 on sensing guide rail 1, in sense
Answer metal derby 2 surface to produce eddy current, and then produce the resistance in opposite direction with elevator cab movement, thus reach to make deceleration of elevator
Purpose, when being declined by elevator, impulsive control is in human-body safety tolerance range, can continuous effective reduce elevator out of control time speed
Degree and energy, make elevator safety only stay, and ensures human life's property safety in car.
