For technology contents of the present invention, characteristics and effect being had more specifically, understand, existing in conjunction with graphic embodiment, details are as follows:
Consult Fig. 7, the transmission rope clutch configuration of a kind of tower crane that first embodiment of the invention provides, be suitable for clipping or unclasp transmission rope, this transmission rope 21 is located at the lifting unit 23 of controlling 22 liftings of stock cage and the suspension unit 24 of controlling suspender (not showing on figure) lifting, wherein this lifting unit 23 comprises lifting mechanism 231, plural number guide wheel 232, limiter of moment 233, lifting change gear 234, little winch 235, this suspension unit 24 comprises plural guide wheel 241, trolley idler wheels 242, suspender roller 243, due to the configuration of this lifting unit 23 and suspension unit 24 and be not that this case invention institute wish is discussed emphasis as flowing mode, therefore repeat no more, consult Fig. 2 to 6, this transmission rope clutch configuration A is mainly by a strap 30, one ambulatory splint 40, three attaching partss 50, three elastic elements 60 and a cylinder pressure 70 form, wherein:
This strap 30, be installed in this stock cage 22, and have the screw 32 that first clip slot 31 and three placed for this transmission rope 21 is equidistant setting.
This ambulatory splint 40, have a pivoting part 41 that is hubbed on this strap 30, a pair of should the first clip slot 31 and be equidistant setting and second perforation 44 of the first perforation 43 and between this first perforation 43 and this second clip slot 42 of corresponding screw 32 respectively for the second clip slot 42, three that this transmission rope 21 places.
This three attaching parts 50, have respectively one and be placed through this first perforation body section of 43 51, one and connect these body section 51 1 ends and spiral shell and establish the location division 52 and that is positioned at these strap 30 screws 32 and connect these body section 51 other ends and form the head 53 of distances with this first perforation 43.
This three elastic element 60 is Compress Spring, be set in respectively the body section 51 of this attaching parts 50, and respectively there is a first end 61 and propped up at this head 53 and prop up the second end 62 at these the first perforation 43 peritreme places, under normality, this elastic element 60 forces this strap 30 and this transmission rope 21 of this ambulatory splint 40 clippings.
This cylinder pressure 70 is oil hydraulic cylinder, also can be air cylinder, this cylinder pressure 70 have a cylinder body 71 that is installed in this ambulatory splint 40, and a scalable action to be located at this cylinder body 71 interior and prop up the piston rod 72 in this geometrical clamp version 30, when this piston rod 72 stretches out, make relative these strap 30 pivots of this ambulatory splint 40 put an angle, in order to do making this strap 30 and this ambulatory splint 40 unclasp this transmission rope 21.
The above is structure and the configuration explanation thereof of each primary member of first embodiment of the invention.
Accordingly, consult Fig. 2,5,7, when the piston rod 72 of controlling this cylinder pressure 70 inside contracts, this ambulatory splint 40 is subject to respectively these elastic element 60 ejections, this ambulatory splint 40 is close in this strap 30, this transmission rope 21 of 42 clippings of the second clip slot of the first clip slot 31 of this strap 30 and this ambulatory splint 40 simultaneously, now, these transmission rope 21 these lifting units 23 of collocation can be controlled this stock cage 22 and carry out lift work.
In addition, consult Fig. 6,7, when the piston rod 72 of controlling this cylinder pressure 70 is overhanging, this ambulatory splint 40 is subject to the ejection of this piston rod 72, make relative these strap 30 pivots of this ambulatory splint 40 put an angle, simultaneously, respectively 60 of this elastic elements are accumulated an elastic restoring force, and the first clip slot 31 of this strap 30 and 42 of second clip slots of this ambulatory splint 40 unclasp this transmission rope 21,21 of this transmission ropes are no longer by clipping, now, this transmission rope 21 these suspension units 24 of collocation can be controlled this suspender and carry out suspension operation.
Be with, the present invention system is located at this transmission rope power-transfer clutch A on the transmission rope 21 of controlling between lifting unit 23 and suspension unit 24, and via controlling the flexible of this cylinder pressure 70, make this strap 30 and ambulatory splint 40 clippings or unclasp this transmission rope 21, reaching the purpose of controlling these lifting unit 23 starts or suspension unit 24 starts.
Consult shown in Fig. 8,9, the transmission rope clutch configuration of a kind of tower crane that second embodiment of the invention provides, be suitable for equally clipping or unclasp transmission rope 21a, this transmission rope clutch configuration A mainly by a strap 30a, an ambulatory splint 40a, a locking cylinder pressure 80a, and a cylinder pressure 70a formed, due to this strap 30a, ambulatory splint 40a, and the structure of cylinder pressure 70a and be same as the first embodiment as flowing mode, therefore repeat no more, be as for the second embodiment difference:
This locking cylinder pressure 80a, but a locking cylinder body 81a and a locking piston rod 82a with relative sliding, this locking cylinder body 81a is arranged on the first perforation 43a of this ambulatory splint 40a, and there is a stopper section 811a who is positioned at outside this first perforation 43a, be located to the scalable action of this locking piston rod 82a in this locking cylinder body 81a and be locked in this strap 30a;
This cylinder pressure 70a, have one and be located in this cylinder body 71a with being installed in the cylinder body 71a of this ambulatory splint 40a and a scalable action and prop up the piston rod 72a at this geometrical clamp version 30a;
When the piston rod 72a of this cylinder pressure 70a stretches out and during this locking cylinder pressure 80a release of pressure, make this ambulatory splint 40a relatively the outside pivot of this strap 30a put an angle, in order to do making this strap 30a and this ambulatory splint 40a unclasp this transmission rope 21a; When this piston rod 72a retracts and this locking cylinder pressure 80a while exerting pressure (this locking piston rod 82a retract this locking cylinder body 81a keep a specified pressure), make the relative inside pivot of this strap 30a of this ambulatory splint 40a put an angle, in order to do making this strap 30a and this transmission rope 21 of this ambulatory splint 40a clipping.
In sum, above-described embodiment and diagram are only preferred embodiment of the present invention, can not limit scope of the invention process with this, and the equalization of generally doing according to the present patent application the scope of the claims changes and modifies, and all should remain within the scope of the patent.
