Description
Technical field
The utility model belongs to elevator technical field, and in particular to a kind of novel limiting controls motor hoist.
Background technology
Traditional motor hoist uses mechanical switching operations, due to the control of cost, the control of minimum point and peak
Mode typically has two kinds：To take over thermal protector on main power line, this protector general performance parameter is one kind：100% electricity
Current test:Not escape, 150% testing current:Escape in 1 hour, 200% testing current:Escape in 40 seconds, 300% electric current are surveyed
Examination:Escape in 10 seconds, closed after cooling；When stroke to minimum point or peak, nut top is forced to limited block motor
Stop, but now motor does not power off yet, and now motor increases, can seen by parameter equivalent to moment overlond running, electric current moment pole
It is uncontrolled to go out the time that such a mode powers off, and electric wire still has the possibility burnt, and after cooling down power-off a period of time
It can close, this mode existing defects.Another way is installation mechanical clutch, when stroke to minimum point or peak
When, nut top to limited block is forced to stop, and the torque that High power output is set in clutch, clutch starts to skid, and sends
The skidding sound rattled away, such a mode also have shortcoming to be conventional, exactly produce noise, and have hinder pair of nut can
Energy.
Utility model content
The purpose of this utility model is to provide a kind of novel limiting control motor hoist, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of novel limiting controls motor hoist,
Including motor, Hall sensor, magnet ring is installed with the motor shaft of the motor, the Hall sensor is arranged on motor
On rear end cap, motor shaft drives magnet ring synchronous axial system, and magnet ring is 8 poles, and the motor is rotatablely connected by decelerator and screw mandrel,
Nut is installed on screw mandrel, promotes nut to move along a straight line, realizes that elevator stretches out retract action.
Further, the screw mandrel is arranged in inner tube, and inner tube is arranged in outer tube, and outer tube is connected with base, on outer tube
Provided with digitial controller, digitial controller is connected with motor by wire.
Using a kind of mode that spacing control is used as by sensing Hall sensor signal, when stroke to minimum point or highest
Nut top is forced to stop to limited block during point, and now controller sets in 50 milliseconds and can't detect hall signal, and system identification is
It is stuck, it will automatically power off, protection circuit；
Controller sets in 50 milliseconds and can't detect hall signal, and system identification is stuck and stroke limit position, Tongfang
It can not be operated to setting is rotated, can only reverse operation；
Control board applies advanced low-pressure injection molding encapsulation technology simultaneously, exhausted using special fire-retardant low-pressure low-temperature heat conduction
Edge material injection is molded, and realizes the hermetically sealed waterproof and dampproof flameproof protection of electronic component, improves security reliability.
Technique effect of the present utility model and advantage：The novel limiting controls motor hoist, more advanced stroke control
Mode processed, using steering of the Hall sensor as detection motor, rotating speed, when stroke to minimum point or peak, nut top is arrived
Limited block is forced to stop, and now controller, which is set in 50 milliseconds, can't detect hall signal, and system identification is stuck, by automatically
Power-off, protection circuit, it is equidirectional rotation setting can not operate, can only reverse operation, can be achieved it is digital control, can be according to user
It is required that the control of setting self-act travel or in real time monitoring stroke height etc., mode of operation can use liquid crystal display panel to control
With using wireless remote control etc..
