Specific embodiment
Please referring initially to Fig. 1 and 2, removable ropewinder 10 of the invention includes a rope rolling unit 20, an auxiliary drive list
Member 30 and a transmission shaft 40.
Rope rolling unit 20 is set in a upper beam (not shown) and has one first pedestal 21, one first wind spring gear 22, one
Second wind spring gear 23, one first wind spring 24, two rope rolling gears 25, two lifting and driving ropes 26 and two brakes 27, in which:
As seen in figures 2 and 3, the first pedestal 21 has one first top plate 211 and one first bottom plate 212, the first top, bottom plate
211, it is linked together between 212 by more first pillars 213.The top surface of first top plate 211 has an apical pore 214 and six
Perforation 215, corresponding first pillar 213 of each perforation 215, aforementioned each first pillar 213 have a communication bores 215
Snap groove 216.
As seen in figures 2 and 3, the first, second wind spring gear 22,23 is rotatably arranged in the first pedestal 21 and bridle joint exists each other
Together, the first, second wind spring gear 22,23 is rotated synchronously can.Again as illustrated in figures 5 and 6, the first wind spring gear 22 has one the
One axis hole 221, the corresponding apical pore 214 for being connected to the first pedestal 21 of first shaft hole 221, and the hole wall of first shaft hole 221 is equipped with one
First clamping portion 223, the first clamping portion 223 have one first polygonal hole 225 (hexagon ring as shown in FIG. 6).
As shown in figures 1 and 3, the first wind spring 24 connects the first, second wind spring gear 22,23, to provide elastic-restoring force
To drive the first, second wind spring gear 22,23.
As shown in figures 1 and 3, which is rotatably arranged in the first pedestal 21 and respectively bridle joint first, second
Wind spring gear 22,23 enables the two rope rollings gear 25 to be driven respectively by the first, second wind spring gear 22,23.
As shown in figures 1 and 3, one end of the two lifting and drivings rope 26 is separately connected a rope rolling gear 25, which passes
The other end of running rope 26 is commonly connected to a underbeam (not shown).
As shown in Figure 1, two brake 27 is set to the both ends of the first pedestal 21, to respectively to a lifting and driving rope 26
The frictional resistance of appropriateness is provided.It is not necessary component of the invention, therefore since brake 70 is only to aid in illustrating the present invention
It can arbitrarily be adjusted in configuration aspects, it might even be possible to which omission is not set.
Auxiliary drive unit 30 has one second pedestal 31, a third wind spring gear 32, a Volume Four spring gear 33 and one
Second wind spring 34, in which:
As shown in Fig. 2, the second pedestal 31 have one second top plate 311 and one second bottom plate 312, the second top, bottom plate 311,
It is linked together between 312 by more second pillars 313, wherein there is a bottom outlet 314 in the bottom surface of the second bottom plate 312, such as
Shown in Fig. 4, bottom outlet 314 corresponds to the apical pore 214 of the first top plate 211 of the first pedestal 21, in addition as shown in Fig. 2, the second bottom plate
312 bottom surface tool there are six engaging portion 315, each engaging portion 315 in a manner of one-to-one corresponding to the first pedestal 21 the
The perforation 215 of one top plate 211.Whereby, as shown in figure 4, the second pedestal 31 can be arranged in the first pedestal 21 by each engaging portion 315
Perforation 215 after be buckled in the snap groove 216 of the first pedestal 21, fit together the first, second pedestal 21,31, so
As long as and release the relationship between engaging portion 315 and snap groove 216, the first, second pedestal 21,31 can be separated.
As shown in figures 1 and 3, third, Volume Four spring gear 32,33 are rotatably arranged in the second pedestal 31 and bridle joint exists each other
Together, third, Volume Four spring gear 32,33 be rotated synchronously can.Again as illustrated in figures 5 and 7, third wind spring gear 32 has one the
Triaxial hole 321, the bottom outlet 314 of corresponding the second bottom plate 312 for being connected to the second pedestal 31 of third axis hole 321, and third axis hole 321
Hole wall be equipped with a third clamping portion 323, third clamping portion 323 have 325 (hexagonal as shown in Figure 7 of a triangle hole
Hole).
As shown in figures 1 and 3, the second wind spring 34 connects the first, second wind spring gear 22,23, to provide elastic-restoring force
To drive third, Volume Four spring gear 32,33.
As shown in Fig. 2,3 and 5, the section configuration of transmission shaft 40 is hexagon, the second pedestal of top drawing-in of transmission shaft 40
31 bottom outlet 314 and be connected in third wind spring gear 32 third clamping portion 323 third polygonal hole 325 in (such as Fig. 7 institute
Show), the apical pore 214 of the first pedestal of bottom end drawing-in 21 of transmission shaft 40 and the first clamping portion for being connected in the first wind spring gear 22
In 223 the first polygonal hole 225 (as shown in Figure 6), due to being the relationship of polygonal section between three, so that the first volume
Spring gear 22 can drive third wind spring gear 32 to rotate together by transmission shaft 40, and third wind spring gear 32 at this time can be nibbled again
Close transmission Volume Four spring gear 33.
It can be seen from the above, under the case where rope rolling unit 20 is used alone, when the two lifting and drivings rope 26 is pulled outward
When stretching and gradually deviating from the two rope rollings gear 25, the two rope rollings gear 25 can respectively engaged transmission the first, second wind spring gear 22,
23, stretch the first wind spring 24 to accumulate elastic-restoring force by the first, second wind spring gear 22,23；On the contrary, working as the first volume
When the elastic-restoring force of spring 24 acts on the first, second wind spring gear 22,23, the first, second wind spring gear 22,23 can be nibbled respectively
It closes and is driven the two rope rollings gear 25, the two rope rollings gear 25 is made to furl the lifting and driving rope 26 being matched therewith respectively.
If under the case where collocation of rope rolling unit 20 auxiliary drive unit 30 is used together, when the first wind spring gear 22
When being driven by the rope rolling gear 25 of institute's bridle joint itself, the first wind spring gear 22 can drive third wind spring gear by transmission shaft 40
32 rotate together, then the further engaged transmission Volume Four spring gear 33 of third wind spring gear 32, make the second wind spring 34 by the
Three, Volume Four spring gear 32,33 is stretched to accumulate elastic-restoring force.As in the first wind spring gear 22 by the first wind spring 24
Elastic-restoring force effect when, the first wind spring gear 22 is also to drive third wind spring gear 32 is reversed together to turn by transmission shaft 40
It is dynamic, make third, the release of Volume Four spring gear 32,33 to the stretching strength of the second wind spring 34, produced by the second wind spring 34 at this time
Elastic-restoring force can auxiliary drive third, Volume Four spring gear 33 rotate backward, until returning to original state.
In conclusion removable ropewinder 10 of the invention can arbitrarily dismount auxiliary drive unit according to actual needs
30, so not only can be used alone rope rolling unit 20, the auxiliary drive unit that can also arrange in pairs or groups 30 operates together, by first,
The collocation of second wind spring 24,34 and the transmission of transmission shaft 40, so that removable ropewinder 10 of the invention has enough retractings
Strength can apply the quantity that additional rope rolling unit 20 is not needed in large scale curtain, so reach reduce cost and
Simplify the purpose of structure.In addition, the first, second wind spring 24,34 is not necessarily intended to using identical specification, elasticity provided by the two
Strength can it is equal or small one and large one, can be adjusted completely in response to actual needs, can be with so in structure configuration
Increase more more options and elasticity.
