Description
Technical field
The utility model relates to the safety guard that uses on a kind of elevator, particularly relates to a kind of safety guard when elevator stall, belongs to elevator equipment technology field.
Background technology
Elevator is as a kind of vertical transportation instrument of skyscraper, and is closely related with people's life and work, in case break down, may the passenger occur stranded, and the Peril Incident such as fall.Along with the development of elevator technology, the safety of elevator progressively improves, but the safety misadventure of elevator faults and non-artificial factor still can occur in daily life, for example: stall occurs in the situation that elevator normally travels, accidental activation etc.These unexpected meeting serious threats cause serious safety misadventure to passenger's life security.
Usually; the bottom of elevator all can be equipped with energy disperser; when preventing used during elevator falling to the impact failure of car; but; energy disperser generally all is installed in the bottom of car or the bottom of hoistway; this can only be as last one program of safety precaution; in the process that elevator stall descends; the passenger can occur in alarm; and; energy disperser can only be remedied the story in certain stalled area, if elevator stall is excessive or skyscraper in the elevator story, the protective effect that energy disperser can play is very limited.
Therefore, be necessary to provide a kind of safe failure-free elevator car safety.
Summary of the invention
For above problem, the utility model provides the fender guard of the Electromgnetic seat on a kind of elevator, can prevent that car from providing protection for elevator when stall decline or stall rising, make the car stop motion, protection passenger's safety.
Specifically, the technical scheme of employing is:
Electromgnetic seat fender guard on a kind of elevator, comprise car, slide unit, fixed parts, electric power system, opening module, central processing unit, velocity-measuring system, it is characterized in that: the both sides of car respectively are equipped with a slide unit, the other end of slide unit embeds fixed parts, and fixed parts is installed on the hoistway both sides along hoistway, and the cross section is groove type, on the part of slide unit embedding fixed parts pulley is installed, pulley contacts with the fixed parts inwall; The interior loop of level is installed in the slide unit, the exterior loop of level is installed in the fixed parts, fixed parts is stretched out and along the fixed parts that enters opposite side after elevator hoistways is arranged in the two ends of exterior loop, and exterior loop 4 is twined hoistways and arranged; Electric power system can provide direct current (DC) to interior loop and exterior loop; Central processing unit is connected with opening module, velocity-measuring system and electric power system.
The Electromgnetic seat fender guard that the utility model provides is like this work:
At first, when the stall campaign appearred in elevator, opening module was sent startup command to central processing unit, and the central processing unit controls electric power system provides direct current (DC) to interior loop and exterior loop.Above-mentioned opening module can be manual opener, also can be automatic control device, and for example, when detecting elevator stall campaign, automatic control device sends instruction to central processing unit immediately.
Electric power system is after the instruction that receives central processing unit, and beginning provides direct current (DC) to interior loop and exterior loop respectively.Owing to existing after the electric current in the coil, all can form magnetic field on interior loop and the exterior loop.The magnetic force direction that forms between two magnetic field should be opposite with the service direction of elevator.For example, when elevator stall descends, make the N level in the magnetic field that exterior loop forms downward, the N level in the magnetic field that interior loop forms upwards, as shown in Figure 4, the magnetic force direction that forms between two magnetic field is by upwards, opposite with the service direction of elevator, can make elevator reduce gradually descending speed.Similarly, when elevator stall is risen, make the N level in the magnetic field that exterior loop forms downward, the N level in the magnetic field that interior loop forms is downward, and like this, the magnetic force direction that forms between two magnetic field is downward, opposite with the service direction of elevator, can make elevator reduce gradually ascending velocity.
As shown in Figure 5, velocity reversal and velocity magnitude that velocity-measuring system is current with elevator are delivered to central processing unit, central processing unit can be sent instruction to electric power system, and electric power system is adjusted electric current, the voltage of power supply, controls accurately with the running velocity to elevator.
Above-mentioned central processing unit can adopt known micro-chip processor, for example, and arm processor.
Elevator speed-measuring instrument Japan three and SE-9000M elevator speed gage.
Electric power system adopts the direct supply of power-adjustable.
