Electric speed governor device for electronic fork lift truck

Abstract

The invention relates to an electric speed governor device for an electronic fork lift truck. The device comprises a substrate, wherein a square rotating shaft is arranged on the substrate and provided with a magnetic steel component; a printed circuit board (PCB) is arranged under the magnetic steel component and provided with a Hall sensor; the magnetic steel component comprises a magnetic steel main body, and the middle lower part, left side and right side of the magnetic steel main body are provided with a magnetic steel respectively; the magnetic steel component also comprises shaft sleeves on two sides of the magnetic steel main body; a direction speed detection module is arranged on the PCB, and signals generated by the magnetic steel and the Hall sensor are transferred to the direction speed detection module; and the direction speed detection module transfers the detected signals to the electronic fork lift truck to control the forwarding, stopping, backwarding and speed of the electronic fork lift truck. By adopting the technical scheme, the contact abrasion in a governing process is eliminated, the reliability is improved, and the service life is prolonged, wherein the speed governor device is still maintained to be normal after working for more than 5 million times when the device is applied, but the service life of the speed governor of a variable resistor only can reach 1 million times.

Description

technical field [0001] The invention relates to the speed regulation and direction control of an electric stacker used in the material handling industry, in particular to an electronic governor device for an electric stacker. Background technique [0002] Most of the governors on electric stackers on the market now use variable resistors to generate speed adjustment signals to control the forward, stop and reverse of electric stackers. Variable resistors are used in electronic governors In fact, contact wear will occur after a long time, which will affect the life and reliability of the electronic governor, and increase the maintenance cost of the electric stacker. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electronic speed controller device for electric stacker vehicles that uses non-contact Hall sensor technology to generate speed adjustment signals, eliminates wear in the adjustment process, improves r...
