Abstract

The invention belongs to the technical field of door devices of subway equipment and relates to a linear motor drive device of a shifting door. A linear motor component is composed of a linear motor stator, a linear motor rotor and a limit base. The limit base is fixed at two ends of the linear motor stator through bolts; a slide component is composed of a slide base, a linear guide rail component, a drag chain plate which are matchedly assembled, a drag chain and a Hall component, wherein the slide base is connected with the linear motor rotator and the linear guide rail component respectively through holts, the linear guide rail component is fixed on one side of the linear motor stator through a bolt, the Hall component is fixed on the slide base through a bolt, and Hall magnetic steel is attached and fixed on the linear motor stator; a number reading head is fixed on the slide base, and a magnetic railing ruler is attached on one side of the linear motor stator; and the Hall magnetic steel is distributed at two ends and in the middle of a whole stroke. The linear motor drive device of the shifting door is simple in structure, reliable in principle, mature in manufacture process, low in manufacture cost, good in operation safety, long in service life, environment friendly, small in noise and occupied space, and free of friction loss.

Description

Technical field: [0001] The invention belongs to the technical field of subway equipment door devices, and relates to a special power drive device for a translation door in a subway equipment, in particular to a linear motor drive device for a translation door used in a subway. Background technique: [0002] At present, with the maturity of linear motor technology, linear motors are widely used in more and more industries, such as construction machinery, medical equipment, aerospace, military fields, catering industry, construction industry and wind power generation. In the subway industry and the international airport special line, many translation electric door devices are generally driven by linear motors, and the special linear motors for translation doors in separate subway occasions have not been reported as drives. The drive of the existing translation door for subway adopts the servo motor to drive the lead screw transmission mode, which is converted from rotary moti...
