Specific embodiment
Applicant illustrates herein first, in the following embodiment that will be introduced and attached drawing, identical appended drawing reference, and table
Show same or similar component or its structure feature.
Please referring initially to Fig. 1 and Fig. 2, Three-wheel type ropewinder 10 of the invention includes a pedestal 20, a driving unit 30, with
An and rope rolling unit 40.
Pedestal 20 is in rectangle and has a top plate 21 and a bottom plate 22.The periphery of top plate 21 has five pairs of upper supporting columns 212, bottom
The periphery of plate 22 has five pairs of lower supporting rods 221, and top, bottom plate 21,22 utilize the snapping of upper and lower pillar 212,221 facing each other
And fit together, after top, bottom plate 21,22 complete assembling, as shown in figure 3, the right end of pedestal 20 has one first opening
23, the left end of pedestal 20 has one second opening 24.In addition, the bottom surface of top plate 21 has three upper whorl axials 214, the top of bottom plate 22
Face has three lower wheel shafts 223, and after top, bottom plate 21,22 complete assembling, upper and lower wheel shaft 214,223 can be with one-to-one side
Formula is connected in together.
Again as shown in Figures 2 and 4, the right end of pedestal 20 has three first upright bars 25, wherein one is located at the first opening
At 23, in addition one be located at pedestal 20 front side edge, adjacent to the back side edge of pedestal 20, the left end of pedestal 20 has last root
Two second upright bars 26,2 second upright bar 26 are connected between top, bottom plate 21,22, wherein one is located at the second opening 24,
Other one is located at the front side edge of pedestal 20.In addition, as shown in Figures 1 and 2, pedestal 20 has more a guide rod 27 and a stop collar
28, guide rod 27 is set to the front side edge of bottom plate 22 and the adjacent lower supporting rod 221 for being set in centre, stop collar 28 are embedded at its of top plate 21
In between two adjacent upper supporting columns 212 and be resisted against the top of guide rod 27.
Driving unit 30 has two wind spring wheels 31 and a wind spring 35.Each wind spring wheel 31 has fluted disc 32,1 the on one first
One lower tooth disk 33 and a first rotating shaft 34, first rotating shaft 34 are rotationally sheathed on a wherein upper and lower wheel shaft for pedestal 20
214,223, and the top of first rotating shaft 34, bottom both ends are integrally connected the first upper and lower fluted disc 32,33 respectively, then as wind spring 35
It is the first rotating shaft 34 for connecting the two wind springs wheel 31, the two wind springs wheel 31 is driven to rotate synchronously to provide elastic-restoring force.
Rope rolling unit 40 has a bull wheel 41, one first lifting and driving rope 48 and one second lifting and driving rope 49, in which:
Bull wheel 41 has fluted disc 42, one second lower tooth disk 43 and one second shaft 44 on one second, the second 42,43 points of upper and lower fluted disc
The upper and lower fluted disc 32,33 of the first of one of wind spring wheel 31 of other bridle joint driving unit 30, the second shaft 44 are rotationally arranged
In a wherein upper and lower wheel shaft 214,223 for pedestal 20, and the top of the second shaft 44, bottom both ends are integrally connected second respectively
Upper and lower fluted disc 42,43, so that bull wheel 41 can be driven by the two wind springs wheel 31 using the relationship of engaged transmission and synchronize rotation
Turn.In addition, as shown in Figures 2 and 3, the second shaft 44 has axle portion 45, a lower shaft portion 46 and a lattice 47 on one, above and below
One end of axle portion 45,46 is integrally connected the second upper and lower fluted disc 42,43 respectively, and lattice 47 is integrally attached to upper and lower axle portion
45, between 46, upper axle portion 45 therein corresponds to the stop collar 28 of pedestal 20, moreover, the outer tooth on second without leave of upper axle portion 45
The direction of disk 42 towards lattice 47 gradually decreases, outer second lower tooth disk 43 without leave of lower shaft portion 46 towards the direction of lattice 47 gradually
It reduces；One end of first lifting and driving rope 48 connects the upper axle portion 45 of the second shaft 44, and one end of the second lifting and driving rope 49 connects
The lower shaft portion 46 of the second shaft 44 is connect, so that the first, second lifting and driving rope 48,49 gives area by the lattice 47 of the second shaft 44
It separates and, to prevent tangled situation.As for the other end drawing-in stop collar 28 of the first lifting and driving rope 48
And guide rod 27 (as shown in Figures 3 and 4) is abutted, it is pierced by outside pedestal 20 via the first opening 23 of pedestal 20 again later, to even
One end of a underbeam (this is the prior art, is not shown in figure) is connect, the other end of the second lifting and driving rope 49 is then via pedestal 20
The second opening 24 to be pierced by pedestal 20 outer (as shown in Figures 3 and 4), to connect the other end of underbeam, can so allow underbeam
The case where single sided taper will not be generated in the pulling by the first, second lifting and driving rope 48,49, so allow underbeam reach by
The average effect of power.
It can be seen from the above, when the first, second lifting and driving rope 48,49 is stretched outward simultaneously and gradually deviates from bull wheel 41
The second shaft 44 upper and lower axle portion 45,46 when, bull wheel 41 can engaged transmission and its phase bridle joint wind spring wheel 31, then by
Wind spring wheel 31 that bull wheel 41 is driven can further another wind spring wheel 31 of engaged transmission, wind spring 35 at this time can by this two
Wind spring wheel 31 is pulled to accumulate elastic-restoring force.Once pulling force suffered by the first, second lifting and driving rope 48,49 releases
When, the elastic-restoring force of wind spring 35 can act on the two wind springs wheel 31, rotate two wind springs wheel, 31 synchronous backward, wherein with volume
The meeting engaged transmission bull wheel 41 of wind spring wheel 31 of 41 phase bridle joint of rope sheave, makes bull wheel 41 by the first, second lifting and driving rope 48,49
Retracting is in the upper and lower axle portion 45,46 of the second shaft 44 simultaneously.
In addition, in order to allow the first, second lifting and driving rope 48,49 in actuation by resistance appropriate, first, second liter
It drops transmission rope 48,49 and distinguishes the first upright bar of pile warp at least one 25 and the second upright bar of at least one 26, in the present embodiment, such as scheme
Shown in 4, the first lifting and driving rope 48 is pierced by via the first opening 23 of pedestal 20 again later around wherein two first upright bars 25
Outside pedestal 20, the second lifting and driving rope 49 is pierced by base via the second opening 24 of pedestal 20 again later around two second upright bars 26
Outside seat 20.However the in fact, winding side of the configuration of the first, second upright bar 25,26 and the first, second lifting and driving rope 48,49
Formula can be adjusted according to actual needs, such as the first, second upright bar 25,26 can be respectively set one or more, and first,
Two lifting and driving ropes 48,49 can bypass wherein one or more first, second upright bars 25,26 respectively, possibly even rotating around
Cross each first, second upright bar 25,26.In other words, by the quantity and position for changing the first, second upright bar 25,26, and
The cabling mode of the first, second lifting and driving rope 48,49 of adjustment in due course, can reach the first, second lifting and driving rope 48,49
Adjust the effect of resistance.
To sum up institute is old, and Three-wheel type ropewinder 10 of the invention is using upper and lower region by the first, second lifting and driving by the way of
Rope 48,49 is set to the same bull wheel 41, and allows bull wheel 41 that can follow the two wind springs wheel 31 using the relationship of engaged transmission
Synchronous actuation so can not influence to shorten whole length under the case where being driven effect, and then realize and simplify structure
Effect.
