Abstract
The utility model relates to an elevator braking device with a position detecting sensor. The elevator braking device comprises an elevator braking device, wherein the position detecting sensor is arranged near the elevator braking device, and is connected with an elevator controller. The elevator braking device has the beneficial effects that the opening distance of a brake of the braking device can be detected in real time, and switching value signals can be given after the brake is completely opened in the prior art, so that the control scheme is greatly optimized, and the heating of a motor and the wear of the braking device are reduced.
Description
Technical field
The utility model relates to a kind of elevator and uses drg, the position probing when relating in particular to the opening of this drg.
Background technology
Control to drg is the core of apparatus for controlling elevator, and it directly influences the life-span of traveling comfort, motor and the drg of elevator.At present, common way is before elevator brake is opened, and detects the weight of lift car earlier through weight sensor; The servo-driver of elevator is issued in the torque that electric life controller changes into motor to the weight of car, servo-driver output zero-speed torque like this, and controller provides drg band-type brake opening signal simultaneously; After mechanical brake is opened fully; The mechanical type limit switch is opened, and electric life controller receives after drg opens information, moves according to direction of setting and speed.During parking, when elevator during to zero-speed actuator send the band-type brake shutdown command, through time-delay after a while, think that drg band-type brake, actuator do not have torque and export with speed.
But owing to use the mechanical type limit switch, can not know the situation that band-type brake is opened in real time, servo-driver output load torque always in drg band-type brake opening and closing process, the cal val of motor is bigger.
Summary of the invention
The utility model technical issues that need to address have provided a kind of elevator brake with position-detection sensor, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: elevator brake; At the other sensor of settling a band position probing of described elevator brake side; Described sensor links to each other with electric life controller.
Compared with prior art, the beneficial effect of the utility model is: can detect the distance that the drg band-type brake is opened in real time, be just to provide the switching value signal after band-type brake is opened fully in the past.Optimize our controlling schemes so greatly, reduced the heating of motor and the wearing and tearing of drg.
Description of drawings
Fig. 1 is the scheme of installation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Visible by Fig. 1: the utility model comprises: elevator brake 1; At the other sensor 2 of settling a band position probing of described elevator brake 1 side; Described sensor 2 links to each other with electric life controller.
The utility model changes the traditional mechanical limit switch into be with displacement detecting sensor, and this sensor in real time detects the distance that drg band-type brake is opened.This sensor is by the power supply of 10VDC power supply, and sensor can be exported to electric life controller to detected actual distance with the form of 0～5VDC analog quantity.Controller is opened distance according to detected actual drg band-type brake, calculates the torque that needs given motor.In the band-type brake opening procedure, motor output torque increases from zero gradually; Close in the closed procedure at band-type brake, motor output torque is to be reduced to zero gradually from load.
The sensor that adopts in the utility model is the commercially available prod.
Electric life controller output 10VDC power supply is given position transduser, and position transduser is exported to electric life controller to detected actual position with the form of 0～5VDC analog quantity.Before the elevator operation, detect the weight of car through weight sensor, the weight of car is exported to controller with the mode of analog quantity, and controller sends operating instruction to servo-driver, and servo-driver output zero-speed and service direction are ordered to motor.Controller provides drg band-type brake opening signal simultaneously; Position transduser detects the distance that band-type brake is opened in real time; And export to controller to it, and controller is set load torque according to the distance of opening of band-type brake to servo-driver, and the setpoint torque of controller is to increase gradually to the open position of load torque according to the drg band-type brake from zero; Before drg was opened fully, controller provided load torque and velocity amplitude.During parking; Servo-driver output load torque, when actual speed equalled zero, controller sent the band-type brake shutdown command; Electric life controller is given servo-driver according to the real time position output controlling torque that detects band-type brake; The servo-driver output torque is reduced to zero gradually from load torque, and after controller detected band-type brake and cuts out fully, controller sent parking order.The open and close of band-type brake all is that motor is accomplished under zero-speed, and the mechanical wear of band-type brake is few.
The utility model has well avoided motor to generate heat for a long time, and greatly reducing drg must wear and tear.
