Abstract
An elevator mechanism with an operation sense belongs to the technical field of automatics. The elevator mechanism comprises a frame body, a revolving body, two buffer bars, two microswitches and a motor, wherein the revolving body is mounted on the frame body through a rotating shaft; a pressure plate is arranged at the front part of the revolving body; the buffer bars are respectively arranged at the upper part and the lower part of the pressure plate and are mounted on the frame body; springs are wound around the buffer bars; the two microswitches are respectively arranged in the upper and the lower positions of the front part of the pressure plate, and contact points of the microswitches are corresponding to the pressure plate; and the two microswitches are respectively connected with the positive pole and the negative pole of the motor. When a heavy object needs to be adjusted finely upwards to ascend, the revolving body is moved upwards, the pressure plate touches the contact point of the lower microswitch, and the motor is activated to run forward, so as to drive the elevator mechanism to lift the heavy object; and when the heavy object arrives the expected height, the revolving body is released, the pressure plate returns back and the motor is stalled. The elevator mechanism can accurately control the ascending/descending of heavy objects, the operation sense is strong and the working performance is safe and reliable.
Description
Technical field:
The utility model belongs to technical field of automation, is a kind of control setup.
Background technology:
The lifting mechanism that uses in the operation process generally adopts button switch that the running of motor is controlled, thus the control adjustable height, and this mode wants to reach difficulty of very accurate aspect ratio.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of lifting mechanism with operation sense that can make things convenient for and control adjustable height exactly.
The scheme of the utility model technical solution problem is to adopt support body, gyro-rotor, shock strut, micro-switch and motor to constitute the lifting mechanism with operation sense, gyro-rotor is installed on the support body by rotating shaft, there is pressing plate the front portion of gyro-rotor, pressing plate be respectively equipped with shock strut up and down, shock strut is installed on the support body, be wound with spring on the shock strut, the upper and lower position of pressing plate front portion has a micro-switch respectively, the contact of micro-switch is corresponding with pressing plate, and two micro-switchs connect the positive and negative electrode of motor respectively.During operation, hold gyro-rotor, weight upwards need be finely tuned when rising, upwards move gyro-rotor, it is downward-sloping that pressing plate overcomes the resistance of shock strut, touches the micro-switch contact of below, starter motor just changes, and lead agency holds up weight, when weight arrives predetermined altitude, unclamp gyro-rotor rapidly, since the effect pressing plate return of shock strut upper spring, the motor stall, and weight stops to rise, weight need be finely tuned downwards when descending, move the gyro-rotor complete operation downwards.
The utility model can be handled the weight lifting exactly, and operation sense is strong, and serviceability is safe and reliable.
Description of drawings:
Fig. 1 is the utility model cutaway view;
Fig. 2 is the utility model structure principle chart.
The specific embodiment:
The utility model is made of support body 1, gyro-rotor 2, shock strut 5, micro-switch 7 and motor 8, gyro-rotor 2 is installed on the support body 1 by rotating shaft 3, there is pressing plate 4 front portion of gyro-rotor 2, pressing plate 4 be respectively equipped with shock strut 5 up and down, shock strut 5 is installed on the support body 1, be wound with spring 6 on the shock strut 5, the upper and lower position of pressing plate 4 front portions has a micro-switch 7 respectively, the contact of micro-switch 7 is corresponding with pressing plate 4, two micro-switchs 7 connect the positive and negative electrode of motor 8 respectively, and the mouth of motor 8 connects the lead screw pair 9 of jacking system.
