Description

Divide three fold door gears in the elevator

Technical field

The utility model relates to the layer door gear technical field in each floor of building that elevator is installed, and especially relates to structure and manipulation with the supporting elevator door of the door opener of large span car.

Background technology

The main means of delivery that has downstairs transported goods on present elevator has become, some measurement of cargo is bigger, and the elevator of domestic use is generally less, designed big lift car, elevator door than large span also must be arranged, divide two film gates or middle branch two folding doors during elevator door of the prior art is generally, the amplitude of opening the door is all little; In case will strengthen the amplitude of opening the door, must increase the width of every film gate, too heavy because of weight, its rotor inertia is too big, causes handling relatively poor, even jeopardizes overall security.

Summary of the invention

The purpose of this utility model is for overcoming the deficiency of prior art, provide a kind of mechanism simple, safe and reliable, elegant in appearance, be easy to assembling adjustment, dividing three fold door gears in the large span elevator of being convenient to keep in repair.

For achieving the above object, the technical solution of the utility model is such: divide three fold door gears in a kind of elevator, comprise upper sill frame, sill, door-plate, the link gear in the upper sill frame, door switch, hanging hook assembly, the left and right sides guide pin bushing on guide rail, both sides, the weight in the guide pin bushing; Said link gear comprises that wire cable transmission mechanism and the door slide plate connecting plate and the said door-plate that are attached thereto have 6, open to both sides by middle symmetry, three on every limit, kinematic velocity difference separately, door-plate have 6, open to both sides by middle symmetry, three on every limit, kinematic velocity difference separately, is respectively that rapid door, middling speed door reach door at a slow speed with the centre to both sides, the ratio of three door displacements is 3/2/1, and every door-plate all fixes with hanging hook assembly respectively, and is set up in respectively on three guide rails by hanging hook assembly; Said STATEMENT OF FEDERALLY SPONSORED is connected with wire cable transmission mechanism, and wire cable transmission mechanism is made up of adapter plate, pulley, steel rope and dynamic resistance part; About in adopt the wire cable transmission mechanism of two cover movable pulley principles between three layer doors dividing, the steel rope fulcrum is chosen on slow the slide plate between rapid door and the middling speed door, and is moving point; The middling speed door and at a slow speed the door between the steel rope fulcrum be the dead point, be chosen on the frame.

Owing to adopted technique scheme, every door-plate weight is little in the large span elevator door of the present utility model, adopt two cover wire cable transmission mechanisms, between three door slide plate connecting plates mechanical linkage is set, guarantee that the switch door is normal, two cover hanging hook assemblies play dragging and the effect of locking a door, and can reduce drawing force; The self-closing effect of weight assembly aliquation door in the guide rod.Therefore switch is normal flexibly, simple in structure, safe and reliable.
