Abstract
Description
- This invention concerns a mechanism which removes the elevator cabin in case of a cutting off of the supply of the electricity and as the cabin reaches next floor (upwards or downwards) its function stops so that people who are trapped in can get out of it.
- Till this day, the technology of constructing elevators in multi-storeyed block of flats cannot offer any mechanism which in case of a cutting off of the supply of the electricity and immobilization of the cabin between two floors, would allow trapped people to exit.
- In this case the elevator cabin is necessary to be removed from its mechanism cabin by a specialist technician or by the door-keeper of the building -if there is one-; until the remove of the elevator cabin, people in it remain trapped.
- The above technical problem led to the research of a technical solution and construction of a mechanism, which can be put in the motor cabin of the elevator and in case of a cutting off of the supply of the electricity it will move an hydraulic pump by force of a direct current accumulator. Thus the hydraulic pump moves an hydraulic motor which coupled in the flywheel of the elevator motor rotates it, so that the cabin can move upwards or downwards (according to the arrangement) and as soon as it reaches to the next floor door, the function breaks off and the trapped people may get out.
- The up-to-day technology (see EP-A-0 065 501 which represents the preamble of claim 1) has not presented any mechanism of removing the elevator cabin with hydraulic pressure situated by the side of the elevator motor and powered by an electric direct current accumulator.
- Another purpose of this invention is to encounter problems of endurance, function and duration of the mechanism by making some improvements which will be presented below in the detailed description scheme. There, all the above as well as more advantages of this invention will be clear.
- This invention will be understood to the specialists of this technique from the sketches which follow this description and in which some preferable industrial applications of this invention are illustrated.
- SKETCH 1 :
- It shows an upper sight of the invention mechanism with the elevator motor to the position before coupling.
- SKETCH 2 :
- It shows the base A.A′ of the hydraulic mechanism and sight B B′ of the fork which moves the male coupling.
- SKETCH 3 :
- It shows the base of the electric mechanism of direct current.
- SKETCH 4 :
- It shows an upper section of the hydraulic piston which pushes the fork and moves the male coupling.
- SKETCH 5 :
- It shows a section of the spiral shaft where the male coupling is driving at and couples with the female which is assembled to the shaft of the motor flywheel.
- SKETCH 6 :
- It shows a section of the female coupling which is assembled to the shaft of the motor flywheel.
- SKETCH 7 :
- it shows a section of the male coupling which couples with the female.
- The component parts of my invention mechanism as they are shown in sketch 1 are the following:
- 1. Base of the hydraulic mechanism.
- 2. Hydraulic motor.
- 3. Oil pressure piston and return by two springs.
- 4. Spiral shaft.
- 5. Male joining coupling.
- 6. Female joining coupling screwed on the shaft of the motor flywheel mechanism.
- 7. Mechanism which moves the male coupling.
- 8. Oil pressure piston which disconnects the break of the motor mechanism and returns automatically to its previous position pressed by an internal spring of the piston during the cutting off of the supply of the direct current accumulator.
- 9. Electric mechanism base.
- 10. Alternative current socket plug
- 11. Direct current accumulator of 12 or 24 VOLT.
- 12. Electromotor button
- 13. Electromotor of 12 or 24 VOLT.
- 14. High pressure pump and oil tank.
- 15. Alternative current relay
- 16. Direct current button in the cabin.
- 17. Reserve light of the cabin.
- 18. Elevator mechanism
- 19. Oil pressure pipe to the piston.
- 20. Oil return pipe from the piston to the tank.
- 21. Oil pressure pipe from the pump to the hydraulic motor.
- 22. Oil return pipe from the hydraulic motor the the tank
- 23. Oil pressure pipe to the piston
- 24. Oil return pipe from the piston to tank
- 25. Break arm of the motor mechanism.
- 26. Two springs of the piston return to its first position.
- During the cutting off of the supply of the electricity the circuit is interrupted in the socket plug 10 and the relay platinum close 15 turning on at the same time the battery circuit 11 through
button 12 and the electromotor starts functioning 13 rotating thehigh pressure pump 14, pressing the oil through thepipe 21 to the hydraulic motor 2 which rotates. - Then the
pipe oil 23 pressed to thehydraulic piston 3, pushes the fork 7, driving thus themale coupling piece 5, which couples with the female coupling piece 6 which is assembled to the shaft of the motor flywheel and rotates it. - During the cutting off of the supply of the electricity the reserve light of the cabin lights automatically up till its restoration and then it turns off.
- In any other damage of the electric circuit without any cutting off of the supply of the electricity, in the cabin there is the button of the direct current accumulator which when pressed, it moves the cabin to the nearest floor and stops automatically allowing the exit of the people.
- All the elevator systems of function security continue to function even when it functions with an electrohydraulic release mechanism.
Claims (3)
- An elevator cabin moving device for an electric elevator motor having a spring activated and hydraulically deactivated lever brake (8,25) and a shaft to which a flywheel is attached, comprising a coupling device (5,6) hydraulically activated to connect a hydraulic motor (2) with the flywheel of the elevator motor, a pump (14) feeding oil to said hydraulically activated lever brake (8,25), motor (2) and coupling device (5,6) during a power failure to rotate the electric elevator motor and thereby permitting the elevator cabin to reach a near floor,characterised in that the hydraulic pump (14) is driven by an electric accumulator (11) and in that the coupling device consists of form-fitted male and female coupling pieces (5,6).
- An elevator moving device according to claim 1, characterised in that the electric accumulator (11) is continuously charged with the elevator current supply.
- An elevator moving device according to claim 1 or 2, characterised in that the female coupling piece (6) is fixed on to the shaft (4) of the electric elevator motor,said shaft (4) being spiral.
