With a concrete application examples principle of work of the present invention is described below:
(1) braking principle of overrunning brake:
The motor operation that descends: motor drives one-level power wheels 1.6 through primary shaft 1.2 and does and rotate counterclockwise (with the A among Fig. 3 to observing); Be moved to the left owing to being engaged on second 1.3 of screw thread simultaneously; When moving to high order end; Drive second 1.3 and rotate counterclockwise together, descend thereby drive weight through transmissions at different levels; (ratchet device 1.11 can't rotate counterclockwise, but because the ratchet movable set of ratchet device 1.11 on brake disc 1.10, thereby can keep motionless its this moment, and second 1.3 carry out left-hand revolution smoothly)
Motor carries out the lifting operation: motor is done through primary shaft 1.2 drive one-level power wheels 1.6 and is clockwise rotated; On second 1.3, move right simultaneously; Be self and ratchet device 1.11 and brake disc 1.10 to be pressed to put firmly link together, when moving to low order end owing to brake disc 1.10 links to each other through flat key with second 1.3; Thereby one-level power wheel 1.6 can drive second 1.3 and clockwise rotate together, thereby weight is promoted; (ratchet device 1.11 is being done and can clockwise rotated smoothly)
The principle that surmounts braking: when the weight accidental falling, drive second 1.3 by transmissions at different levels and do left-hand revolution, one-level power wheel 1.6 will move right self and ratchet device 1.11 and brake disc 1.10 pressed to put firmly and link together that (sense of motion for one-level power wheel 1.6 can be analyzed like this this moment; Because the relativism of motion, this moment, one-level power wheel 1.6 was motionless, did left-hand revolution for second 1.3; Its movement effects and second 1.3 are motionless, and one-level power wheel 1.6 is done along the rotation of pointer direction always, thereby can know according to the principle of above-mentioned " motor carries out the lifting operation ": one-level power wheel 1.6 will move right self is pressed to put with ratchet device 1.11 and brake disc 1.10 firmly and link together); To drive ratchet device 1.11 for second 1.3 conveniently and carry out left-hand revolution; And ratchet device 1.11 since cooperating of ratchet and ratchet can't carry out left-hand revolution, thereby will make second 1.3 can't be rotated; Thereby guaranteed when the unexpected tenesmus of weight; Even under the situation that motor braking lost efficacy, overrunning brake also can be braked quickly, simultaneously; Owing to cooperate through multiple screw thread between one-level power wheel 1.6 and second 1.3; Thereby make braking distance reduce greatly, accelerated speed of response, more guaranteed the quick and safety performance of braking.
More than analyze and be merely a certain concrete application mode, technical personnel is according to principle of the present invention, and the relevant design that the hand of rotation of double thread trend, ratchet device is made change is all within protection scope of the present invention.
(2) principle of work of safety clutch;
Taper hole gear 1.8.1 and awl friction wheel 1.8.2 carry out transmission through friction force; Elastic force through adjustment disk spring 1.9.2 makes itself and the taper hole gear 1.8.1 and the friction force of boring between the friction wheel 1.8.2 be in state of equilibrium; When the lifting weight transships; Taper hole gear 1.8.1 and awl friction wheel 1.8.2 will be in slipping state, and friction force reduces, and this moment is under the elastic force effect of disk spring 1.9.2; Taper hole gear 1.8.1 can realize overrunning separating with awl friction wheel 1.8.2, thereby has played protective effect.
Those skilled in the art also can adopt other overload protective device commonly used to realize this function.
