The specific embodiment
As Fig. 1, a kind of screw thread awl blow-up compact form winch brake device shown in Figure 2, comprise brake coupler 1, transmission shaft 2, transmission shaft 2 one ends are realized interlock with brake coupler 1 by adapter sleeve 5, circlip 6 is set in transmission shaft 2 terminations is used to prevent that longitudinal travel from appearring in transmission shaft 2, described transmission shaft 2 adopts spline to be connected with adapter sleeve 5, the other end of transmission shaft 2 is provided with block 21, transmission shaft 2 is provided with the tapered cup nut 3 that is threaded with transmission shaft 2, described being threaded is preferably: transmission shaft 2 is provided with the bull outside thread of coarse-pitch, and tapered cup nut 3 inwalls be provided with transmission shaft 2 on the corresponding negative thread of outside thread.5 of tapered cup nut 3 and adapter sleeves are provided with preloading spring 7, carry out pretension by 7 pairs of tapered cup nuts of preloading spring 3 and transmission shaft 2,21 of tapered cup nut 3 and blocks are provided with brake hoop 4, one end of brake hoop 4 inwalls is provided with the conical suface that matches with the appearance inclined-plane of tapered cup nut 3, the other end of brake hoop 4 is pressed on the side of block, in order to increase braking effect, described block 21 profiles are set to taper, block 21 is the inclined-plane with the contact surface of brake hoop 4, the inclined-plane of the inclined-plane of tapered cup nut 3 and block 21 is oppositely arranged, and can provide bigger friction force when brake.Described brake hoop 4 is made up of three arc brake plates 41 that are the minor arc shape, has made things convenient for brake hoop maintenance and replacement.
Extremely shown in Figure 6 as Fig. 3, radial symmetry is provided with two raised lines 11 on brake coupler 1 inwall, one end of described tapered cup nut 3 is provided with connecting portion 31, radial symmetry is provided with two lugs 311 on connecting portion 31 peripheries, radial symmetry is provided with two lugs 51 on the periphery of described adapter sleeve 5, two lugs 51 on the adapter sleeve 5 are resisted against respectively on two heteropleural faces of two raised lines 11, two lugs 311 on the connecting portion 31 are resisted against respectively on two other heteropleural face of two raised lines 11, make adapter sleeve 5 and tapered cup nut 3 round stroke of phase difference of half in rotation.
Principle of work of the present utility model is as follows: brake coupler 1 is connected with the motor output shaft of capstan winch, transmission shaft 2 then is connected with the input shaft of winch reductor, as shown in Figure 6, if the traction operative orientation of capstan winch is a left-hand revolution, and the left-hand revolution of tapered cup nut 3 is for loosening, then capstan winch is when starting traction, and the raised line 11 of brake coupler 1 is rotation conic nut 3 at first, and fastening tapered cup nut 3 is loosened.
When braking coupler 1 when turning over half-turn, raised line 11 is rotationally connected and overlaps 5, make adapter sleeve 5 and tapered cup nut 3 with equidirectional, same rate rotates mutually, because of adapter sleeve 5 is connected with transmission shaft 2, be transmission shaft 2 with tapered cup nut 3 with equidirectional, same rate rotates mutually, therefore can not produce relative displacement between transmission shaft 2 and the tapered cup nut 3, just can not make 4 of tapered cup nut 3 and brake hoops produce friction force yet.
When windlass work is stopped, transmission shaft 2 reverses under the effect of load, be transmission shaft 2 clickwises, what the coupler 1 that brakes this moment at first promoted also is tapered cup nut 3, clickwise takes place in tapered cup nut 3, not and axially can not being moved of transmission shaft 2, therefore have only tapered cup nut 3 that relative displacement takes place, as shown in Figure 2, the left-hand revolution of tapered cup nut 3 is for loosening, so tapered cup nut 3 in clickwise to brake hoop 4 near and compress brake hoop 4, brake hoop 4 is squeezed and moves to the right until compressing block 21, and the inclined-plane combined action of the inclined-plane of tapered cup nut 3 and block 21 at this moment produces the reverse friction force with respect to load on brake hoop 4, and the big more reverse friction force of load is also just big more, and capstan winch is realized auto lock.Be divided into two kinds of situations when capstan winch starts once more: first kind is to draw once more, and the raised line 11 of brake coupler 1 promotes tapered cup nut 3 left-hand revolutions once more, carries out traction work again after the tapered cup nut 3 that will screw in will braking last time loosens; Second kind of situation is to put rope, it is capstan winch motor clickwise, therefore be in locking state between tapered cup nut 3 the time and the brake hoop 4, but transmission shaft 2 is with brake coupler clickwise, in like manner, the relative tapered cup nut 3 of the clickwise of transmission shaft 2, just left-hand revolution takes place in tapered cup nut 3, because of transmission shaft 2 can not move axially, therefore have only tapered cup nut 3 that relative displacement takes place, the left-hand revolution of tapered cup nut 3 loosens the brake hoop 4 of locking, and capstan winch is put rope work.
In sum, no matter capstan winch is traction, brake or puts rope that always brake coupler 1 loosens tapered cup nut 3 earlier, carry out work again, and adopt the tight mode of awl blow-up to carry out self-actuating brake, braking quality is reliable, and is safe; Automatically work when capstan winch operation Halfway Stopping is worked drawbar load is stopped, when capstan winch restarted operation once more, drg was opened automatically simultaneously, and capstan winch can normally draw and put rope, can be used for all horizontally tracting operation capstan winches; The apparatus structure simplicity of design is reasonable, and cost of manufacture is low.
