The centre position stated between a pair of of rubber column is provided with range sensor, is used for the state of feedback security rope.
Further, the photoelectric sensor is fixed on by strut in safety device.
Further, when safety rope is tied tight, a pair of of rubber column is acted on, the power that a pair of of rubber column overcomes spring is made inwardly to receive
Contracting closes fan after sensor sensing.
Further, the side of the support ring and the first articulation piece are provided between the fixed connecting rod of support ring
Reinforcing rib.
Further, the position at top is provided with controlling valve in the side of the sealed cylinder of the buffer unit, uses
In stroke of the control fender pile in sealed cylinder.
A kind of Industrial fan with safety rope noise reduction of the present invention, by the way that buffer unit is arranged, buffer unit one end is hinged
Support ring, other end hinged blades, support ring form bearing with support ring with the fixed upper fixed ring of shell and lower fixed ring, make
Blade while rotating, can keep damping state, and can keep stopping, moreover, being provided with safety rope, be rolled in blade
It when disconnected or deformation, is protected by safety rope, and promptly stall, improves safety；It is compact-sized, it is simple easy to install.
Description of the drawings
Fig. 1 is a kind of schematic diagram of Industrial fan with safety rope noise reduction of the present invention；
Fig. 2 is a kind of schematic diagram of the safety device of Industrial fan with safety rope noise reduction of the present invention.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings and examples.
As illustrated in fig. 1 and 2, a kind of Industrial fan with safety rope noise reduction, including blade 3, shaft 2 and the shell above it
1；Fixed ring 4 and lower fixed ring 5 are arranged on the shell；It is provided with support ring between fixed ring and lower fixed ring
6, it is embedded with ball 7, the outer circle side of 6 bottom surface of support ring and lower fixation between the outer circle side and upper fixed ring of the support top surface of ring
It is embedded with ball 7 between ring, fixed ring, support ring and lower fixed ring is made to form a bearing；The lateral surface of the support ring
Orientation corresponding with blade is hinged with buffer unit by the first articulation piece 11；The buffer unit includes sealed cylinder 10, and one
End is plugged in the fender pile 13 in cylinder 10；The other end of the fender pile and the top surface of blade are hinged；Above the blade also
It is fixed with safety rope 8, one end of safety rope is fixed on the left end of blade, the other end is fixed on the right end of safety device 9；The guarantor
Dangerous device is internally provided with a pair of of rubber column 14, and safety rope is wrapped on a pair of of rubber column 14；Between a pair of of rubber column 14 there are
Space is simultaneously provided with spring 15；Centre position between the pair of rubber column is provided with range sensor 17, for feeding back peace
The state restricted entirely；The photoelectric sensor is fixed on by strut 16 in safety device；When safety rope is tied tight, a pair of of rubber is acted on
