Description
Technical Field
The utility model relates to a device that emergent was hauled when the elevator had a power failure, concretely relates to be applied to the lifesaving emergency device who tows the formula elevator.
Background
At present, an elevator often encounters a power failure accident in the running process, and at the moment of power failure, an elevator controller can automatically brake a traction wheel of the elevator, so that the elevator car is fixed, and passengers in the elevator car can forcedly break the elevator door to escape. However, at the moment when the elevator brake brakes the traction sheave of the elevator, the elevator car may also stop between the upper and lower floors, and at this time, opening the elevator door is dangerous for escape, and escape from the top of the elevator car is troublesome.
Disclosure of Invention
An object of the utility model is to provide a be applied to lifesaving emergency device who tows formula elevator, when meetting the power failure at the elevator operation in-process, can fix a position elevator car in floor exit position.
In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a be applied to lifesaving emergency device of traction formula elevator which characterized in that: the emergency motor, the clutch and the detection trigger are respectively electrically connected with the controller, the standby power supply supplies power to the emergency motor, the clutch, the detection trigger and the controller, when the elevator power supply is disconnected, the output shaft of the emergency motor is in transmission connection with a flywheel of the elevator main motor through the clutch, and the controller starts the emergency motor according to the position of the elevator car to drive the elevator car to ascend or descend to a floor elevator opening.
Further, the emergency motor is a double-steering forced-mesh starter motor.
The clutch is an electromagnetic clutch.
The controller is a PLC controller.
The utility model has the advantages that: adopt above-mentioned structure, simple structure is novel, and convenient to use can meet when having a power failure at elevator operation in-process, fixes a position elevator car in floor exit position, and the security performance is high, has very strong practicality and spreading value.
Concretely, if meet the power failure accident in the elevator operation process, detect the starting device and detect outage signal and give the controller with signal transmission, the actuation of controller control clutch, make emergency motor's output shaft and elevator main motor's flywheel transmission be connected, get into the position that the original system of elevator acquireed elevator car through the controller simultaneously, start emergency motor, drive elevator car rises or descends to floor elevator mouth position, at this moment, emergency motor stall, the controller intervenes the original system elevator car door of elevator once more and opens automatically, the passenger can flee safely by oneself.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. an emergency motor; 2. a clutch; 3. detecting a trigger; 4. a controller; 5. a standby power supply; 6. an elevator main motor; 7. a reduction gearbox; 8. a traction sheave; 9. dragging the steel wire rope; 10. a guide wheel; 11. an elevator car; 12. balancing weight; 13. and a brake.
Detailed Description
As shown in fig. 1, the utility model relates to a be applied to lifesaving emergency device of traction type elevator, including emergency motor 1, clutch 2, detection trigger 3, controller 4 and stand-by power supply 5. The existing traction type elevator comprises an elevator main motor 6, a reduction gearbox 7, a traction sheave 8, a traction steel wire rope 9, a guide pulley 10, an elevator car 11, a counterweight 12 and a brake 13, and the specific structure and the working principle of the elevator are the prior art and are not described in detail herein.
The utility model discloses during the application, emergency motor 1 installs on elevator well top computer lab to emergency motor 1's output shaft passes through clutch 2 and is connected with elevator main motor 6's flywheel transmission, detects trigger 3 and is used for detecting the elevator power break-make and conveys outage signal for controller 4. The controller (4) is connected with an elevator control system and can acquire the position of the elevator car. The standby power supply 5 supplies power to the emergency motor 1, the clutch 2, the detection trigger 3 and the controller 4.
When the elevator encounters a power failure accident, the brake 13 brakes the elevator traction sheave, so as to position the elevator car 11. At the moment, the controller 4 controls the clutch 2 to be sucked, so that the output shaft of the emergency motor 1 is in transmission connection with the flywheel of the elevator main motor 6, meanwhile, the controller is involved in the original system of the elevator to obtain the position of the elevator car, the emergency motor 1 is started to drive the elevator car 11 to ascend or descend to the position of a floor elevator opening, at the moment, the emergency motor 1 stops rotating, the controller is again involved in the original system of the elevator to automatically open the elevator car door, and passengers can escape automatically and safely.
The emergency motor 1 has large torsion, and can still forcibly drive the elevator motor to rotate under the condition that the elevator brake brakes. In the present embodiment, the emergency motor 1 employs a double-steering forced-mesh type starter motor.
The clutch 2 is an electromagnetic clutch; stable structure and convenient control.
The controller 4 is a PLC controller.
The above description is only for the purpose of illustrating the technical solutions of the present invention, and the simple modification or equivalent replacement of the technical solutions of the present invention by those of ordinary skill in the art does not depart from the spirit and scope of the technical solutions of the present invention.
