A permanent magnet frequency conversion rack transmission door opener comprises a door head, a transmission mechanism and an asynchronous door cutter. A door head guide rail is provided with a left following chain and a right following chain. A guide support and a guide plate are installed between the left following chain and the right following chain, and an auxiliary lock is installed on the right following chain. Rope wheels are installed on the two sides of the bottom of the door head respectively, and a steel wire rope winds around the two rope wheels. A left door hanger plate and a right door hanger plate are in linkage through the left following chain and the right following chain via the steel wire rope. Auxiliary lock plugs are installed at the positions, corresponding to the auxiliary lock, of the left door hanger plate and the right door hanger plate. The transmission mechanism is composed of a motor, a gear and a rack. The motor is installed on the door head. The gear is installed on a motor shaft. The rack is installed on the right door hanger plate and meshed with the gear. The permanent magnet frequency conversion rack transmission door opener is simple in structure, flexible in installation, convenient to maintain, small in occupied space and low in energy consumption.
Description
Technical field: [0001] The invention belongs to the technical field of elevators, in particular to a door opener driven by a permanent magnet variable frequency rack drive. Background technique: [0002] The elevator door machine controls the opening and closing of the car door. The automatic door machine widely used in my country uses a 110V permanent magnet synchronous motor as the power supply, and drives the car door to open and close through the deceleration mechanism and the door opening mechanism. The main mechanism of this kind of door machine includes car door head plate, guide rail, timing belt, connecting arm, hanging plate and motor. Realize the switch action of the car door. The driving system and the transmission system of this type of door machine are integrated, so the structure is more complicated, the floor space is large, the installation and maintenance are difficult, the energy consumption is high, and it is not suitable for the use of cars with vario...
