Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-3, an electromagnetic braking device on a hoisting apparatus includes a motor 1 as a driving mechanism of the hoisting apparatus and an electromagnet 4 for braking instead of a braking structure, wherein the motor 1 and the electromagnet 4 are both installed inside the hoisting apparatus, and the motor 1 and the electromagnet 4 are powered on the same circuit.
Wherein, the front end of motor 1 is equipped with the output shaft 3 that stretches out, has fixed the installation a brake gear 2 on the output shaft 3, and brake gear 2 is through pressing the mode fixed mounting of riveting on output shaft 3, along with the coaxial rotation of output shaft 3.
The top of the electromagnet 4 is provided with a movable sliding rod 5, a sliding rod gear ring 6 is fixedly mounted on a rod body of the sliding rod 5, a cavity is formed in the electromagnet 4 and can accommodate the sliding rod 5 and the sliding rod gear ring 6 to be retracted into the electromagnet 4, the sliding rod 5 can lift up and down, the sliding rod gear ring 6 is fixed on the sliding rod 5 in a press riveting mode, and the sliding rod gear ring 6 can be clamped into a tooth groove 7 in the brake gear 2.
In the practical use of the device, the output shaft 3 of the motor 1 is connected to a winding drum for winding the cable, and as long as the motor 1 is braked and cannot rotate, the winding drum cannot rotate, so that the hoisted goods stop at a required position; therefore, when the lifted goods need to be stopped, the motor 1 is powered off only by pressing down a switch on a power supply circuit of the motor 1, meanwhile, the electromagnet 4 is powered off, the electromagnet 4 cannot generate magnetic force to adsorb the sliding rod 5 under the condition of no electricity, so that the sliding rod 5 is popped up, the sliding rod gear ring 6 is also lifted, at the moment, the output shaft 3 of the motor 1 can continue to rotate due to inertia at the moment of power failure, the sliding rod gear ring 6 can be clamped into the tooth grooves 7 of the brake gear 2, only the two tooth grooves 7 need to be clamped, the brake gear 2 can be clamped by the sliding rod gear ring 6, the brake gear cannot rotate, the output shaft 3 stops rotating, the motor 1 is braked, the electromagnetic induction time in the whole process can be almost ignored, the brake gear 2 can be clamped by the sliding rod gear ring 6 at the moment, and the brake effect is greatly due to the traditional brake structure; when the brake needs to be released, the motor 1 is only required to be electrified, the electromagnet 4 is also electrified, electromagnetic induction is generated to suck the sliding rod 5 back, the sliding rod gear ring 6 is separated from the brake gear 2, and the motor 1 can normally rotate to drive the hoisting equipment.
