Abstract

The invention relates to a large flexible door hoisting machine, comprising a decelerating device and two winding drums, wherein the decelerating device comprises a planet reducer and a gear box; two ends of each wingding drum are respectively connected on a fixing plate a back side plate and are connected with the decelerating device through a motor output shaft and a coupling; the gear box comprises an output gear which is arranged in the gear box, fixed on an output shaft of the reducer and respectively meshed with left and right gears; left and right pinions are coaxially arranged on the left and right gears and respectively meshed with winding drum gears on two winding drum shafts; reversing gears meshed with the left or right pinion are arranged at left or right of the output gear; and the speed is low through two-time deceleration but the torque is high and the braking is reliable. According to the invention, as two wingding drums are driven by a motor with a conical rotor to synchronously work, the energy is saved, the driving is stable and soft and low in noise and the phenomena that two sides of a door curtain is not synchronous, not uniform in height and not good in sealing are thoroughly eliminated; and two steel wire ropes with a same direction and different angles can be simultaneously pulled out by utilizing one winding drum to ensure that the pulling force of the winding drum is increased, the pulling force of the door curtain is more uniform and the start and stop of a flexible door is speeded up in the meantime.

Background technology

Along with science and technology and expanding economy, manufacturing manufacturing scale also increases day by day, especially the required production site of the manufacturing of the vehicles such as steamer, aircraft is large, manufacturing shop and extraneous isolation are prevented dust in order to make, sun-proof, rainproof, insulation, because the vertical height of steamer, aircraft is very large, therefore height, the width for the manufacture of the required door in workshop is also very roomy.

Patent No. CN200920097129.3 " large-scale flexible lever gear door ", just provide a kind of for the used large-scale flexible door in large-scale manufacturing shop, its body is by double-deck software door curtain and the integral body that consists of with the door curtain rib that steel welding is connected into, the wire rope hook that stretches out with the electric block that is fixed on the crossbeam is fixed on the end rib, promote and drive end rib and upwards operation of middle rib with the electric block rotation with wire rope, electric block stall gate is opened when reaching setting height, otherwise the gate is closed.

Patent No. CN200920251690.2 " large-scale flexible lever gear door anti-off device ", what provide only is the wire cable rupture of lever gear door, when getting loose, safety hook can in time pin end rib, can effectively prevent falling of a body, ensures Field Force's safety.

Summary of the invention

Technical problem to be solved by this invention is: a kind of large-scale flexible door elevator is provided, is installed in the middle of the large-scale flexible header crossbeam, its compact conformation, volume are little, but Fraquent start, and output torque is large, and stable drive is shockproof, and noise is low, long service life.

The present invention addresses the above problem the technical scheme that adopts: large-scale flexible door elevator, comprise the support in stationary power source and the fixing fixed head of deceleration device, and be connected with link with cable drum, and all be fixed on the integral body that consists of on the base plate, the first stage decelerator that described deceleration device is made of planetary reduction gear and the two stage reducer that is consisted of by gear-box, described link is connected into by base plate by fixed head and back side panel, on the described link left side is installed, right two winding drum, the two ends of each reel are connected on fixed head and the back side panel, described power source is a motor, pass through motor output shaft, shaft coupling and planetary reduction gear, gear-box connects, described gear-box is by the output gear that is fixed in the gear housing on the planetary reduction gear output shaft, respectively with a left side, left side on the right axle, the right gear engagement, left, on right gear is coaxial a left side is arranged, right pinion respectively with the two winding drum axle on reel gear engagement, the left side or the right at output gear also have one and left or right pinion, the tumbler gear that is installed on the reversing shaft forms, described reversing shaft is fixed on the fixed head, a described left side, the two ends of right axle are separately fixed on fixed head and the side cover plate.

Compared with prior art, the invention has the advantages that: the reductor of this elevator adopts the planetary gear type structure, carries out the first order its smooth running that slows down, and without radial thrust, compact conformation, volume are little, lightweight, have greatly prolonged the life-span of bearing and gear.And then by gear-box deceleration increase moment; Commutation is carried out the second level and is slowed down, and the wire rope that only adopts a motor to drive on the right and left reel moves up and down, and rolls or put down door curtain, because of large through twice slow torque of its speed of slowing down, braking is reliable.Because driving the two winding drum synchronous working with a conical rotor machine, stable drive is soft, noise is low, former door curtain both sides have thoroughly been eradicated because of asynchronous, the height that unbalance stress produces is uneven, the dead doorframe of folder causes bursting collapses, seals not good phenomenon, only in gear-box, increase a tumbler gear, rotate towards different directions with regard to two reels of an available driven by motor, reduced by a motor and can reach energy-saving and cost-reducing purpose.This motor energy Fraquent start, also adopt elastic coupling to be connected with reducer, effect with damping, buffering, the reel periphery has the groove of smooth surface circular arc in addition, rope guide makes wire rope be difficult for loosening wearing and tearing during use, can pull out simultaneously on the reel two equidirectional, two wire rope of different angles, each two wire rope about two reels can be pulled out simultaneously, by being fixed on the fixed pulley of diverse location on the large-scale flexible door crossbeam, be fixed on equably on the base cross members of large-scale flexible door after wire rope is turned to, not only effectively utilized the pulling force of reel, made again the pulling force of door curtain more synchronous evenly; Also accelerate simultaneously the speed that the large-scale flexible door opens and closes, used safety and reliability.
