The invention discloses a variable speed control system of an electric hoist. The variable speed control system of the electric hoist comprises a machine frame, a button housing fixed to the machine frame and provided with two vertical wall grooves, an elastic button installed in the button housing and capable of vertically moving, a connecting rod penetrating through the vertical wall grooves and a hole formed in the elastic button and capable of vertically moving in parallel, a shifting rod provided with a first end point, a first elongated hole and a second elongated hole, a sliding rail fixed to the machine frame, an optical grating strip arranged on the sliding rail, only capable of moving along the sliding rail and provided with a pin, two pairs of position sensors for detection a position signal of the optical grating strip and a controller, wherein the first end point is hinged to the machine frame, the connecting rod is sleeved in the first elongated hole, the pin is sleeved in the second elongated hole formed in the shifting rod, the elastic button is artificially operated and controlled, the connecting rod vertically moves and drives the shifting rod to rotate and drives the optical grating strip to move, and finally the motor is controlled to change rotation speed. The variable speed control system has the advantages of being convenient to control and high in control accuracy.
Description
technical field [0001] The invention relates to a variable speed control system of an electric hoist. Background technique [0002] With the update of electric hoist technology, its application range is getting wider and wider, and various demands are increasing, especially the requirements for operating speed. People operate the control buttons, and the existing electric hoist control buttons cannot realize multi-stage speed change, and cannot fully utilize the speed change characteristics of the speed-adjusting electric hoist. Contents of the invention [0003] Based on the above disadvantages, the present invention provides a variable speed control system for an electric hoist, which can change the speed of the motor by manipulating buttons. [0004] Technical scheme of the present invention is: [0005] A variable speed control system for an electric hoist, characterized by comprising: [0006] frame; [0007] The button housing is fixed on the frame, and the butto...
