It hangs oneself and is connected to spring 8, hung in the lower end of spring 8 and be connected to up-small and down-big wedge block 9, up-small and down-big wedge block 9 is provided in rectangle
In slot, the drag hook 10 in the case where the lower end of up-small and down-big wedge block 9 is provided with L-shaped wedge block is arranged in the groove bottom of rectangular channel
There is shaft hole 24, shaft set 23 is provided in shaft hole 24, shaft 12 is movably set in shaft set 23, the one of shaft 12
End is arranged in rectangular channel, and the other end of shaft 12 stretches out outside the trailing flank of lifting base 1, in the shaft in rectangular channel
12 end set, which has link 11, link 11, to be overlapped with the lower end of drag hook 10 under L-shaped wedge block, is risen reaching
It drops and is provided with flywheel needle bearing 22 on the set of the shaft on the other end of the shaft 12 outside the trailing flank of pedestal 1 23, rolled in flywheel
It is provided with flywheel 21 on needle bearing 22, is fixedly installed on the end face of the other end of the shaft 12 outside the trailing flank of lifting base 1
Castle wheel 25 is rotatably compressed, pawl support is fixedly installed on the outer end face of flywheel 21 for rotatably compressing 25 outside of castle wheel
Pin 26 is hinged with curved pawl 27 in pawl supporting pin 26, is provided on the trailing flank of the lifting base 1 below flywheel 21
One end of guide wheel shaft 15, guide wheel shaft 15 is arranged in rectangular channel, and the other end of guide wheel shaft 15 is arranged in the trailing flank of lifting base 1
Outside, guide wheel 16 is provided on one end of the guide wheel shaft 15 in rectangular channel, guide wheel 16 is in rolling contact together with riser guide 7,
Belt driving wheel 18 is provided on the other end for the guide wheel shaft 15 being arranged outside the trailing flank of lifting base 1, in belt driving wheel
Feed belt 20 is provided between 18 and flywheel 21.
It is provided with front side surface cover 17 on the leading flank of rectangular channel, belt is provided on the trailing flank of lifting base 1
Contact roller 19；The top spring mounting hole 13 being provided on lifting base 1 on rectangular channel Right Inboard face lower part 3 on left and right directions,

Both ends are both provided with pawl major part 28.
When elevating mechanism normally declines, the lifting base 1 being fixed together with elevating mechanism is under normal speed
Drop, guide wheel 16 normally scroll down through on riser guide 7, and guide wheel 16 drives guide wheel shaft 15 and belt driving wheel 18 to rotate, skin
Band driving wheel 18 drives flywheel 21 to rotate by feed belt 20, and flywheel 21 is with pawl supporting pin 26 also normal rotation, in spine
Curved pawl 27 in pawl supporting pin 26 normally moves in a circle, and curved pawl 27 is not contacted with castle wheel 25 is rotatably compressed；This
When shaft 12 it is motionless during decline, the link 11 of the end set of shaft 12 is articulated in one with drag hook 10 under L-shaped wedge block
It rises, spring 8 is made to be in tensional state, up-small and down-big wedge block 9 is in the lower section of the wedge groove on the top of rectangular channel, and in outstanding
Dummy status.
When elevating mechanism stall declines, the lifting base 1 that is fixed together with elevating mechanism will appear suddenly plus
The phenomenon of speed, guide wheel 16 can also accelerate downwards to roll on riser guide 7 suddenly, and guide wheel 16 drives guide wheel shaft 15 and belt actively
18 rotation of wheel, belt driving wheel 18 drive flywheel 21 that can accelerate to rotate suddenly by feed belt 20, the acceleration suddenly of flywheel 21
Rotation, can be such that 27 run-off the straight of curved pawl in pawl supporting pin 26 rotates, pawl major part 28 is stuck up under the action of the centrifugal force
It rises, one end of curved pawl 27 is made to be contacted with castle wheel 25 is rotatably compressed, drive rotatably compresses the rotation of castle wheel 25, rotatably compresses
Castle wheel 25 can drive shaft 12 to rotate, and keep the link 11 of the end set of shaft 12 and the mounting of drag hook 10 under L-shaped wedge block de-
It opens, after the lower end of up-small and down-big wedge block 9 loses traction, spring 8 can be by up-small and down-big wedge block 9 relative to lifting base 1
It moves upwards, up-small and down-big wedge block 9 enters in the wedge groove on 1 top of lifting base, by lifting base 1 and riser guide 7
Together, lead to 1 OQ t guide rail 7 of lifting base moves downward stopping to clamping stagnation, play prevent lifting base 1 and with its phase
The elevating mechanism of connection will not stall decline.The present invention not only realizes that breaking rope protecting can also precisely realize overspeed protection, mechanism
Without electrical equipment control, safety and reliability.
