Description
Technical field
The present invention relates to a kind of anti-drop device, particularly a kind of anti-drop device for industrial big fan.
Background technique
Current existing fastening piece is generally bolt, and to join spring pad, nut and tight split nut etc. fastening, but there is vibration characteristics and the refitting that hangs on the personnel crown, work-yard is put, only inadequate with such security insurance measure, once bolt bears shearing fracture or screw gets loose and will cause the accident.
Summary of the invention
The object of the present invention is to provide one to achieve weight reduction, convenient installation, improve the anti-drop device for industrial big fan of Security.
The present invention is for solving the problems of the technologies described above, provide a kind of anti-drop device for industrial big fan, comprise motor frame and chassis, be provided with motor in motor frame, the protuberance outer circumferential face on chassis is provided with large ring, and the end of chassis protuberance is provided with little ring, motor is provided with motor shaft, the upper end of motor shaft is connected with motor, and the lower end of motor shaft is connected with chassis, and large ring and cyclotella sleeve are contained on the outer circumferential face of motor shaft; The outer circumferential face on chassis is set with the anti-decylization of level, and the anti-decylization of level is provided with some Y type plug connectors, and Y type plug connector is provided with perforate; Y type plug connector is provided with flabellum attachment hole.
Further, described little ring is connected with chassis by little collar bolt.
Further, described chassis, large ring and motor frame are connected by large collar bolt.
Further, the lower end of described motor shaft is connected by fixed block with chassis.
The present invention achieves following technique effect: large ring and little ring can effectively early warning and prevent chassis and link thereof from falling from motor shaft downwards, fixed block when motor shaft and chassis lost efficacy, during the downward landing of the flabellum of chassis and connection thereof, the severe friction of large ring and little ring can be caused and sounding; When Y type plug connector is inoperative, flabellum and chassis are thrown off, and the anti-decylization of level still effectively connects flabellum by flabellum attachment hole, effectively prevents flabellum radial direction from getting rid of de-causing the accident by its symmetrical circumferential pulling force.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the anti-drop device of industrial big fan.
Fig. 2 is the structural representation on chassis of the present invention.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figures 1 and 2, a kind of anti-drop device for industrial big fan, comprise motor frame 9 and chassis 1, be provided with motor 8 in motor frame 9, the protuberance outer circumferential face on chassis 1 is provided with large ring 3, and the protuberance end on chassis 1 is provided with little ring 4, motor 8 is provided with motor shaft 2, the upper end of motor shaft 2 is connected with motor 8, and the lower end of motor shaft 2 is connected with chassis 1, and large ring 3 is sleeved on the outer circumferential face of motor shaft 2 with little ring 4; The outer circumferential face on chassis 1 is set with the anti-decylization 12 of level, and the anti-decylization of level 12 is provided with some Y type plug connector 10, Y type plug connectors 10 and is provided with perforate 11; Y type plug connector 10 is provided with flabellum attachment hole 13; Little ring 4 is connected with chassis 1 by little collar bolt 6, and chassis 1, large ring 3 and motor frame 9 are connected by large collar bolt 7, and the lower end of motor shaft 2 is connected by fixed block 5 with chassis 1.
Large ring of the present invention 3 and little ring 4 can effectively early warning and prevent chassis 1 and link thereof from falling from motor shaft 2 downwards, when the fixed block 5 of motor shaft 2 with chassis 1 lost efficacy, chassis 1 and connect flabellum downward landing time, large ring 3 and the severe friction of little ring 4 and sounding can be caused; When Y type plug connector 10 is inoperative, flabellum and chassis 1 are thrown off, the anti-decylization 12 of level still effectively connects flabellum by flabellum attachment hole 13, and its symmetrical circumferential pulling force effectively prevents flabellum radial direction from getting rid of de-causing the accident.
Present invention achieves weight reduction, the convenient General installed, increase insurance link, improve Security etc.
