The invention discloses a double-speed quick door opener, which comprises a double-speed motor, an electromagnetic brake arranged at one end of the double-speed motor, a reduction box arranged at the other end of the double-speed motor, and a controller for adjusting a connection mode between the double-speed motor and an external alternating-current power supply. The double-speed motor comprisesa shell and a motor rotating shaft which is arranged in the shell and extended out of two ends of the shell, a friction disc is fixed at one end of the shell, and the reduction box is arranged at theother end of the shell; and the electromagnetic brake comprises a magnet yoke base, an armature is movably arranged on one end face of the magnet yoke base, a plurality of springs are arranged between the armature and the magnet yoke base, a clearance is formed between the magnet yoke base and the armature due to the elastic action of the springs, a brake disc is arranged on the armature, a gear sleeve is sleeved in the center of the brake disc, the electromagnetic brake is arranged at the end of the double-speed motor for mounting the friction disc, and the motor rotating shaft extended out of the end of the double-speed motor provided with the friction disc is fixed into the gear sleeve of the electromagnetic brake.
Description
【Technical field】 [0001] The invention relates to a fast door opener, in particular to a two-speed fast door opener. 【technical background】 [0002] Industrial fast rolling doors such as industrial fast door openers are widely used in medicine, food, chemical, electronics, logistics, supermarkets and other industries due to their fast opening speed, windproof, dustproof, heat preservation, and safety. The limit of the industrial fast door opener is directly related to the safety of personnel and vehicles, as well as the accuracy and service life of the opening and closing of the rolling shutter door. [0003] Existing industrial fast door openers all control the rotating speed of the motor by adding a frequency converter in the control box, so that the fast rolling door can be lifted and lowered quickly and accurately. However, the cost of the existing industrial quick door opener is extremely high because of the high price of the frequency converter; at the same time, the ...
