Description
Technical field
The utility model relates to a kind of door opener, particularly a kind ofly is used to open or the door lifter of slide-lifting door such as close the plant, commerce, garage.
Background technology
Existing door lifter structure is: a frame is arranged, have first and second that is parallel to each other in the frame upper support, first joins with drive unit, and drive unit mostly is the motor that is fixed on the frame, motor drives first rotation by belt pulley and belt transmission, forms one-level and slows down.Between first and second, be provided with chain-drive mechanism, promptly make first to drive second rotation, form the second level and slow down by pair of sprocket and the chain that is fixed on first and second.Be provided with the sprocket chain strip transmission mechanism between the torsion axis on second and the slide-lifting door, form the third level and slow down.After three grades of decelerations, the rotation of torsion axis can drive the slide-lifting door action, reaches the purpose that opens or closes door.Though the door lifter technology of this structure is simple, easily make, but, its speed reducing ratio is less, in practice, total gearratio can only be controlled between 1: 35～1: 42 after three grades of decelerations, because speed reducing ratio is little, causes poor stop, therefore, must strengthen braking device, braking device is to utilize the close of friction plate that magnet control contact with the motor braking vane or leave the braking that realizes door lifter, after use a period of time, attenuation along with friction plate, gap between braking vane and the friction plate can increase, and brake force can diminish gradually, even brake failure, influence is normal to be used, electromagnet also can often break down, and needs often debugging or changes parts, increases maintenance time.If the increasing speed reducing ratio then need increase jackshaft on frame, realize multi-stage speed-reducing, so both increased the volume of equipment, take effective space, make equipment complicated again, make troubles for the overall installation of door lifter.
The mode that adopts worm and gear to slow down is also arranged at present, its speed reducing ratio is usually between 1: 55～1: 65, though worm and gear ways of deceleration self-locking performance is better, speed reducing ratio also than the former bigger, but also undesirable, the lubrication oil in the worm reduction box need regularly replace, oil body is obvious with summer in winter variations in temperature in the case, when temperature is low, may occur solidifying, unfavorable to the startup of motor; In order under power failure or other situation, to realize manually must arrangement of clutch being housed in the motor shaft rear end, make complex structure, cost increases.
Summary of the invention
The purpose of this utility model provides that a kind of speed reducing ratio is big, braking good, compact conformation, stable and reliable operation, moment of torsion are big, need not frequent adjust or change parts, door lifter that cost is low, overcomes the deficiencies in the prior art.
Door lifter of the present utility model, it comprises frame 1, on frame 1, be equipped with first 23 and second 17 that join with drive unit, on first 23, be fixed with first output wheel 5, on second 17, be fixed with second wheel for inputting 20 and second output wheel 9.Be provided with transmission between first output wheel 5 and second double linked wheel 30, second double linked wheel 30 is sleeved on second 17 and between the two for being rotationally connected, be provided with transmission between second double linked wheel 30 and first double linked wheel 31, first double linked wheel 31 is sleeved on first 23 and between the two for being rotationally connected, is provided with transmission between first double linked wheel 31 and second wheel for inputting 20.
Door lifter of the present utility model, wherein said transmission are the sprocket wheel chain drive.
Door lifter of the present utility model, wherein said driving device structure is: be fixed with motor 2 on frame 1, be provided with the belt transmission pair between motor 2 and first 23.
Door lifter of the present utility model is equipped with manual chain type clutch 7 on wherein said first 23.
Door lifter of the present utility model is equipped with braking and kills mechanism of car 3 on the wherein said motor 2.
Door lifter of the present utility model, wherein said second 17 connects position-limit mechanism 32.
Door lifter of the present utility model, owing to being provided with transmission between first output wheel 5 and second double linked wheel 30, second double linked wheel 30 is sleeved on second 17 and between the two for being rotationally connected, be provided with transmission between second double linked wheel 30 and first double linked wheel 31, first double linked wheel 31 is sleeved on first 23 and between the two for being rotationally connected, be provided with transmission between first double linked wheel 31 and second wheel for inputting 20, therefore, three grades of decelerations between first and second, have just been formed, changed the mode of having only one-level to slow down in the prior art between the diaxon, so under the situation that does not increase intermediate propeller shaft, increased the speed reducing ratio of complete machine, has following advantage: the increase of speed reducing ratio, improved braking ability, safe and reliable, operate steadily; Complete machine takes up room little, and compact conformation is easily installed; Moment of torsion is big, causes having higher hoisting power, can join single-phase 220V and three-phase 380V motor, opens the slide-lifting door maximum area and can reach 70 square metres, and the unlatching rolling door can promote gravity and reach 1 ton, opens the output torque that translation door can provide 800 Ns of rice; The motor of being furnished with band brake promotes or vertical ultra-large type door height, brakes, brakes higher to the spacing degree of accuracy; Need not regularly to adjust or change parts, significantly reduced maintenance time, cost is low.
