Description
Technical field
The utility model relates to a kind of kickoff mechanism that uses on horizontal opening door machine, door-rolling machine, industrial door machine.
Background technology
The present kickoff mechanism that uses at horizontal opening door machine, door-rolling machine, industrial door machine, when worm and gear meshes, because worm and gear has auto-lock function, and worm gear is connected with flat key with output shaft, output shaft and door fuse, when under situations such as power failure, installation, maintenance, need carry out manual open and close door, this moment is extremely inconvenient.Because gearbox generally adopts this Worm-gear type, solves this technical problem of this self-locking and has become a urgent problem.
Summary of the invention
The purpose of this utility model is to overcome this technical deficiency, aims to provide a kind of quick kickoff mechanism that can manually carry out the door lifter of switch door under situations such as door lifter installation, maintenance and outage fast.
The quick kickoff mechanism of door lifter of the present utility model, it comprises reduction box housing, spring, adapter sleeve, alignment pin, steady pin, shift fork, sear, output shaft, worm gear, worm screw, and output shaft is fixed on the reduction box housing with back-up ring by bearing, bearing (ball) cover, hole; The worm gear sky is enclosed within on the output shaft, axially by shaft block ring worm gear is being blocked, and can rotate freely on output shaft, be fixed with steady pin on the end face of worm gear, adapter sleeve is connected with spline with output shaft, and the relative output shaft of adapter sleeve can carry out axially-movable, and can not rotate; Spring is arranged on output shaft, porose on the described adapter sleeve, the steady pin that described spring handle adapter sleeve is pressed on described worm gear and the worm gear inserts adapter sleeve, worm gear fuses by adapter sleeve and output shaft, output shaft rotates freely relatively, shift fork is fixed on the deceleration box by alignment pin and shift fork can freely rotate around alignment pin, and an end of described shift fork is fixedlyed connected with adapter sleeve, and the other end is fixedlyed connected with sear.
Described steady pin is three, the Kong Weiliu on the described adapter sleeve.
Described shift fork and adapter sleeve are fixing can be meant that the adapter sleeve external surface has annular groove, and shift fork is a ring, thereby described ring is stuck in the groove both are linked into an integrated entity.The described shift fork end that is connected with sear can be a deep-slotted chip breaker, by pin both is linked into an integrated entity.Described shift fork also can be a bar.
During use, shift fork is outwards swung along alignment pin behind sear Rotate 180 °, outwards moves from wearing the cover that is dynamically connected, and steady pin and adapter sleeve on this moment worm gear break away from, and worm gear can rotate along output shaft, thereby door can carry out hand switch; When 180 ° of sear cycles, adapter sleeve inserts in the connection trepanning three steady pins on the worm gear under the effect of spring, and worm gear fuses by adapter sleeve and output shaft, realizes motor switch, door.
Quick kickoff mechanism according to above-described door lifter has characteristics such as simple in structure, easy to operate.
Figure of description
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In Fig. 1, reduction box housing 1, spring 3, adapter sleeve 4, alignment pin 11, steady pin 5, shift fork 12, sear 15, output shaft 10, worm gear 6, worm screw 13 etc., described output shaft 10 is fixed on the reduction box housing 1 with back-up ring 8 by bearing 2, bearing (ball) cover 7, hole; Worm gear 6 skies are enclosed within on the output shaft 10, worm gear 6 is axially being blocked worm gear 6 by shaft block ring 9, on worm gear 6 and adapter sleeve 4 opposing end faces steady pin 5 is arranged, and adapter sleeve 4 is connected with output shaft 10 usefulness splines, adapter sleeve 4 relative output shafts 10 can carry out axially-movable, and can not rotate; On output shaft 10, be fixed with spring 3, porose on the described adapter sleeve 4, described spring 3 is pressed to the hole that the steady pin 5 on described worm gear 6 and the worm gear 6 inserts in the adapter sleeve 4 to adapter sleeve 4, worm gear 6 links into an integrated entity by adapter sleeve 4 and output shaft 10, output shaft rotates freely relatively, shift fork 12 is fixed on the deceleration box 1 by alignment pin 11, and an end of described shift fork 12 is stuck on the adapter sleeve 4, and the other end of shift fork 12 has a kidney slot; A cam pin 14 is housed on the sear, and cam pin 14 inserts in the kidney slot of shift fork, and sear 15 is fixed on the deceleration box, can carry out 180 ° rotation.
