Abstract
The utility model relates to an electric door opening machine which comprises a machine frame, an induction motor, a worm screw, a worm wheel, a clutch, an output shaft and an output wheel. The utility model is characterized in that the clutch uses a tooth-inlaid type taper surface clutch; the clutch is linked with the hollow output shaft by an on-off transverse pin; an on-off push-out mechanism and a reset mechanism are arranged in the output shaft; the clutch is matched with a normal open switch which is connected with a time relay. The utility model overcomes the defects of the ordinary electric door opening machine, such as large structure volume, low technical level, low reliability, and no automatic protection devices for limitation, failure work, clamping and over-loading. The utility model has the advantages of convenient and flexible operation, long service life, high automatization degree, wide application range and reasonable design.
Description
The utility model relates to a kind of electric door-opening machine.
The door lifter of commonplace use all is to pass through the V belt transmission by a motor and reducer, assembles, and its shortcoming is that structural volume is big, no-clutch, and rainproof humidity resistance is poor, and no overload protection has been in the level that is eliminated.For addressing the above problem, a kind of more novel electric door-opening machine has appearred again, and its worm screw is provided with grinding disk; and accompany wearing piece, but it also exists driving torque short simultaneously, the defective of unstable properties; in use, realize opening and closing the gate by voltage regulation screw and stage clip, wearing piece skids, weares and teares big under overload; and motor can not autostop, when regulating driving torque, does not have the permanent position; as transfer De Taisong; then moment reduces, as transfer tension, then overload protection lost efficacy.During power failure, clutch handle need rotate a few just can finish separation, and the clutch degree is provided with fixed data, spacing when malfunctioning, and motor can not autostop, and above-mentioned variety of problems causes great inconvenience for user's use.The purpose of this utility model is the above-mentioned defective that overcomes prior art, can realize autostop under spacing malfunctioning, overload, stuck state thereby provide a kind of, and convenient manual operation, safe and reliable electric door-opening machine.
The utility model comprises frame, induction machine, worm screw, worm gear, clutch, output shaft and output wheel, worm screw is connected with induction machine, worm gear matches with clutch, the center socket output shaft of worm gear and clutch, the affixed output wheel of one end of output shaft, clutch adopts castellated conical clutch, and by clutch lateral pin and output shaft interlock, output shaft is a hollow shaft, its axial wall is provided with the chute that moves for the clutch lateral pin, in the one side output shaft of clutch lateral pin is blind hole, be provided with return push rod and return spring, be provided with the clutch push rod in the opposite side output shaft, the end that the return push rod is relative with the clutch push rod offsets with the clutch lateral pin respectively, the external advance and retreat device of the other end of clutch push rod, and the advance and retreat device symmetrical screw inclined plane interior with being fixed on frame matches, one side of clutch also is provided with normal open switch, and the normal open switch and the time relay link.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1
As shown in the figure, the utility model comprises frame 1, induction machine 2, worm screw 3, worm gear 4, clutch 5, output shaft 6 and output wheel 7, worm screw 3 is connected with induction machine 2, worm gear 4 matches with clutch 5, the center socket output shaft 6 of worm gear 4 and clutch 5, the affixed output wheel 7 of one end of output shaft 6, clutch 5 is castellated conical clutch, and by clutch lateral pin 8 and output shaft 6 interlocks, output shaft 6 is a hollow shaft, its axial wall is provided with the chute 9 that moves for clutch lateral pin 8, in the one side output shaft 6 of clutch lateral pin 8 is blind hole, be provided with return push rod 10 and return spring 11, be provided with clutch push rod 12 in the opposite side output shaft 6, return push rod 10 offsets with clutch lateral pin 8 respectively with clutch push rod 12 relative ends, the external advance and retreat device 13 of the other end of clutch push rod 12, advance and retreat device 13 and fixed frame 1 interior symmetrical screw inclined plane 14 matches, one side of clutch 5 also is provided with normal open switch 15, normal open switch 15 links with the time relay 16, advance and retreat are provided with advance and retreat pin 17 in the device 13, and advance and retreat pin 17 and fixed frame 1 interior locating piece 18 matches.Under normal operating condition, induction machine 2 drives worm screw 3, worm gear 4 rotates, and by the effect of clutch 5, makes clutch lateral pin 8 drive output shaft 6 and output wheel 7 rotations, finishes the action of open and close door.Spacing malfunctioning, under overload or the stuck state, because castellated conical clutch 5 and the horizontal slip of clutch lateral pin 6 in chute 9, return push rod 10 moves right, return spring 11 is compressed, clutch 5 triggers normal open switch 15, by the time relay 16 induction machine is quit work, after this, return spring 11 and return push rod 10 reset, clutch 5 is got back to the normal occlusion state, during power failure, move back device 13 when rotating, because the effect of symmetrical screw inclined plane 14 by advance and retreat handle 19, advance and retreat device 13 and clutch push rod 12 advance, clutch 5 is separated with worm gear 4, at this moment, can be by manually finishing the shutter door operation.Because the matching relationship of the locating piece 18 in advance and retreat pin 17 and the fixed frame 1 makes the rotation of advance and retreat device 13 be controlled between 100 °-120 °.
The utility model is by above-mentioned concrete structure, have easy to operate, flexible, rapid, reliability strong, long service life, advantage that automaticity is high, is a kind of electric door-opening machine applied widely, reasonable in design.
