Specific embodiment

Fig. 1 to Fig. 3 illustrates the first embodiment of the device for producing annular hoist cable.The device, which includes, to be passed through Crank 4 surrounds the first guide reel 2 of rotation axis 2a rotation, and can be around the second guide reel 6 of rotation axis 6a rotation. Both rotation axis 2a and 6a are maintained in rack 8 and are arranged to be parallel to each other.Close to the first deflection of the first guide reel 2 Roller 10 is maintained in rack 8 around rotation axis 10a, and is maintained at close to the second deflection roll 12 of the second guide reel 6 It allows it to rotate around rotation axis 12a in rack 8.In the example illustrated herein, rotation axis 10a, 12a are mutually flat Row.

In this embodiment, the first and second guide reels 2,6 and the first and second deflection rolls 10,12 form guiding element Part, the induction element limit cricoid closed circulation path, with the starting strand for accommodating annular first and then receiving Looping strand 14.Looping strand 14, which has substantially to extend on the circulating path formed by induction element or be parallel to this, to follow The central longitudinal axis 16 that endless path extends.Looping strand 14 has scheduled circumferential lengths along its longitudinal axis 16.

By moving induction element on loop direction, originates strand or looping strand 14 can be along longitudinal axis It line 16 and is moved along circulating path.

In the case where embodiment according to figure 1, when induction element movement, guide reel 2,6 clockwise movements, Then direction of rotation 2b, 6b shown in are moved in Fig. 2 and Fig. 3.Deflection roll 10,12 is along direction of rotation as shown in Figs. 1-3 The direction 10b, 12b rotation, so that looping strand 14 is moved along circulating path, continuously along its longitudinal axis 16.

Illustrated by understanding such as Fig. 2 and Fig. 3, guide reel 2,6 is respectively provided with tapered perimetral surface 2c, 6c, looping strand 14 are guided along the tapered perimetral surface.It is arranged close to guide reel 2,6 and is located at relative to the movement of looping strand 14 and draws Deflection roll 10,12 before deflector roll 2,6 is arranged so that looping strand 14 is wound up into guidance after being rolled off from deflection roll 10,12 On the winding point of tapered perimetral surface 2c, 6c of roller 2,6, the winding point is arranged to relative to rotation axis 2a, 6a than being detached from The bigger radius of point, looping strand 14 are detached from the dispersal point from guide reel 2,6.Hereby it is achieved that looping strand 14 is along half The lesser path of diameter shuttling movement on tapered perimetral surface 2c, 6c, and due to its specified longitudinal tension force, it being capable of edge The direction of small radii obtain the trend that is rolled off on the peripheral surface, and thus surround its own 16 turns of longitudinal axis It is dynamic.

Rotation axis 10a, 12a of deflection roll 10,12 are respectively slated for guide reel 2,6, they preferably with guide reel Rotation axis 2a, 6a extend spaced apartly, they make looping stock relative to the axial position of rotation axis 2a, 6a Line 14 is wound up on the winding point on taper circulation surface of guide reel 2,6 after the disengaging of deflection roll 10,12, the radius phase of winding point It is sufficiently large for the radius of dispersal point such as at least bigger than the radius of dispersal point by 10%, 20%, 30%, 50%, 100%, 150% or 200%.Local longitudinal axis relative to looping strand is obliquely with the rotation of angle of twist positioning deflection roll 10,12 Shaft axis 10a, 12a.They follow looping strand thus according to the vector obtained from the rotary motion of longitudinal movement and superposition Outer surface movement, and support the continuous rotation of looping strand.

The peripheral surface of guide reel 2,6 needs not be the taper or circular cone that radius increases in a linear fashion along rotation axis Shape；On the contrary, the radius of peripheral surface can increase in a non-linear manner along rotation axis 2a, 6a and the twist increases with it or subtracts It is small, as visible in axial section.Associated be winding point on looping strand 14 to peripheral surface be in than At the bigger radius of dispersal point, fortune is rolled off and rotated around its longitudinal axis so that triggering looping strand therebetween It is dynamic.

Optionally, the first and/or second guide reel 2,6 can use cylindrical guide reel substitution, wherein looping strand is first It guides via deflection roll and is guided on spiral path then along cylindrical circumferential surface, thus also result in looping strand Around the rolled off motion and rotation for surrounding its longitudinal axis.

If starting strand there is specific minimum diameter be for example, at least final looping strand 10%, 15%, 20%, 25%, 30%, 40% or 50%, and there is circular cross section, then it can aid in and be rolled off, reason is The trend of flattening of the looping strand on guide reel or induction element is correspondingly cancelled.

According to one of the device of Fig. 1 to Fig. 3 or above-mentioned modification, it can be ensured that looping strand 14 is recycling Every bit on path all surrounds its longitudinal axis continuous rotation, only directly running in deflection roll 10,12 in circulating path The regional area of very little can make an exception.

Method for producing annular hoist cable can be executed specifically on the device according to Fig. 1-3, and the first step will be imagined Be along cricoid closed circulation path setting annular starting strand (such as a trap close, along longitudinal direction axis have it is specified The winding strand of circumferential lengths).Starting strand is connected to wind strand the in feeding point place's feeding in adjacent cycle path One end.

Starting strand moves on the traffic direction along its longitudinal axis in a looping fashion along circulating path, while along pre- Fixed direction of rotation surrounds its fore-aft axis.During the shuttling movement of starting strand, winding strand 20 is given in fixed A continuous feeding at sending, wherein winding strand be helically wrapped on the starting strand around its fore-aft axis and at the same time It moves on the circulating path along its longitudinal axis or is moved on the looping strand of growth.With starting strand or looping stock Line is along each turn of circulating path, it just increases a circle winding strand, until realizing the pre- fixing turn of looping strand.Institute Some coils are all spirally arranged with certain angle of twist of the longitudinal axis around looping strand.The geometry that angle of twist passes through arrangement Shape predefines and corresponds to the twist of the ring by biasing or the helix with formation.Because of looping stock during manufacture The perimeter of line increases and angle of twist is constant, so the circle number of looping strand continuously subtracts relative to the distance advanced along circulating path It is small.Finally, the free end for winding strand is fixed to looping strand, and the final annular that can be taken out from device is consequently formed and hangs Rope.

Fig. 4 and Fig. 5 illustrates the second embodiment for producing annular hoist cable.In the case, induction element is by first Guide device 30 and the formation of second guide 40.First guide 30 has circulating element, and form is a series of follows Ring 32a, 32b, 32c and 32d, they be respectively disposed on circulation plane in around rotation axis or circulation axis 32a ', 32b ', 32c ' and 32d ' rotation.Circulation axis 32a ', 32b ', 32c ' and 32d ' are arranged to be parallel to each other and along circular arc with one Fixed spacing separates, and the circular arc and drive shaft or guide reel 34 are concentric, and the drive shaft or guide reel can be surrounded and be parallel to The rotation axis 34 ' of the rotation axis of circulating ring is driven.

Circulating ring 32a, b, c, d are positioned to make its inner surface 36a, 36b, 36c, 36d in a manner of irrotational and drive shaft 34 outer surface forms the engagement of non-imposed or shape cooperation, e.g. friction pairing or corresponding inside and outside engagement.

The bearing of circulating ring 32a, b, c, d can be realized for example, by several bearing roller (not shown), be distributed in interior Surface 36a, b, c, d are upper and are rolled off from thereon, and their rotation axis is parallel to the rotation axis of circulating ring.It therefore ensures that The rotation axis of circulating ring is fixed with the position relative to drive shaft 34 relative to each other, and is consolidated whole relative to device It is fixed.

Circulating ring 32a, b, c, d or circulation plane be positioned to be closely adjacent to each other so that along rotation axis 32a ', b ', c ', The direction of d ' is not present between the circulating ring of direct neighbor or only minimum intermediate space.

The structure of second guide 40 circulating ring 42a, b, c, d similar and possessed with first guide 30 Can around the rotation axis that is mutually offset or circulation axis rotation, and in a manner of non rotatable with 44 phase of drive shaft or guide reel Engagement, the drive shaft or guide reel can be rotated and be driven around rotation axis 44 '.The inner surface of circulating ring is with non-imposed Or the mode of shape cooperation is for example non-rotatingly connect by frictional engagement or corresponding inside and outside engagement with drive shaft 44 It closes.

The rotation axis 32a ' of circulating ring 32a, b, c, d of the rotation axis 34 ' and first guide 30 of drive shaft 34, B ', c ', d ' are set as that (they and drive shaft are flat with the rotation axis of the circulating ring of drive shaft 44 ' and second guide 40 Row) it is angled, the angle is 90 degree in the illustrated embodiment, in practice can be between 0 degree to 120 degree. The selection of proper angle by such as material and can be used to form looping strand and be wound the frictional property of strand, circulating ring Surface nature and frictional property, coil longitudinal tension force during movement and circulating ring are relative to rotation axis 32a ', 42a ' Between the factors such as the size and arrangement of mutual distance influence, but mainly by the space geometry of the circulating path of looping strand Shape determines, and is used to keep the sum of all deflection angles small as far as possible.When in deflection roll, the longitudinal axis around looping strand turns The dynamic deflection without guiding force each time may all adversely affect result.

Each guide device 30,40 further include around clinoid 38 ', 48 ' pivot first or second deflection roll 38, 48.Corresponding clinoid 38 ', 48 ' is arranged to the rotation axis of adjacent driven axis 34,44 corresponding to respective guide device 34 ', 44 ' is separated by a distance.The effect of deflection roll 38,48 be limit looping strand 14 circulating path so that its via Each circulating ring 32a, b, c, d and 42a, b, c, d advance.At each guide device 30,40, circulating path is via about 180 The circumferential angle of degree is advanced, this corresponds to the track of looping strand 14, so that since the position of contact deflection roll, until leaving The last one circulating ring 32d or 42d, looping strand integrally deflect about 180 degree.After contacting deflection roll 38,48, looping stock Line 14, which continues on through, is advanced by each circulating ring 32a, b, c, d or 42a, b, c, d and is supported by each circulating ring, de- from circulating ring From, then slightly guided, until looping strand leaves corresponding guide device 30,40 towards off-direction, the disengaging Direction is opposite with coiling direction.

Clinoid 38 ', 48 ' is positioned by looping strand relative to the angle of twist of its longitudinal axis, so as to according to it Motion vector follows the movement of the outer surface of looping strand and supports the rotation as continuous as possible of looping strand.

It is dominant in looping strand in view of intrinsic tension or longitudinal tension force, therefore in the region of guide device 30,40, follows Endless path away from the smallest feasible distance of rotation axis 34 ', 44 ' or radius to advance, to set shortest feasible circulating path.

It is consistent with the movement of looping strand 14 around the rotation direction of travel of its axis in view of each circulating ring, therefore It, by period, is especially stuck on circulating ring at it and carries out between different circulating rings around guide device 30,40 Transition period, looping strand 14 are continuously rotated around its longitudinal axis 16.

Its reason consists in the fact that guide device 30,40 and the not formed consistent deflector surface itself fixed, such as Including the situation of a component just as guide reel, but looping strand passes sequentially through each circulating ring, while each circulation Circle also moves relative to each other.In view of the friction between looping strand and circulating ring, looping strand tends to around the longitudinal direction of its own Axis is rotated and is rolled off from circulating ring.

Fig. 6 and Fig. 7 illustrates the 3rd embodiment of the device for producing annular hoist cable, separate with second embodiment phase It is similar.Imagine in this embodiment also includes first guide 50 and second guide 60, annular 14 edge of looping strand The closed circulation path of annular is guided around it.Here, the circulating ring of second embodiment by circulation strand 52a, b, c, d, E, f, g, h and 62a, b, c, d, e, f are substituted.The present embodiment illustrates following fact simultaneously: the circulation in each guide device The exact amount of strand be it is incoherent, this is also applied for second embodiment, wherein can be arranged different number such as two, Three, five or more circulating rings, or the circulating ring for each guide device 30,40 setting different number.

Each circulation strand 52a, b, c, d, e, f, g, h is around central actuating shaft or guide reel 54 and 54 ' quilt of rotation axis On the other hand guidance is then guided around circulation roller 56, the circulation roller 56 surrounds the rotation axis being arranged to guide reel 54 54 ' parallel and separated by a distance circulation axis 56a, b, c, d, e, f, g, h are pivoted.Recycle axis 56a, b, c, d, e, f, g, H is arranged to be mutually offset certain angular distance 58 in circumferential direction in the rotation axis 54a observation relative to guide reel 54 And it is arranged successively.Be set to each circulation axis 56 on previous circulation axis 56a, b, c, d, e, f, g, c, d, e, f, g, H has certain angular distance 58 relative to previous circulation axis, and the angular distance can respectively not for different circulation axis It is identical and without keeping constant.As the example of such case, being directed to Fig. 6, (it illustrates the constant angular distances of circulation axis From) modification in, angular distance between adjacent circulation axis can be increased or decreased when observing along circumferential direction, and for example It can be between 10 ° to 30 °.

Analogously with the mode of second embodiment, it is arranged around the deflection roll 59 that clinoid 59a is pivoted in guide reel At a certain distance from before 54.Clinoid 59a is arranged to be separated by a spacing with the rotation axis 54a of adjacent guide reel 54 From.In addition, the peripheral surface for the deflection roll 59 that looping strand 14 is guided on it is biased in the rotation along guide reel 54 It is separated by a distance with first circulation strand 52a when the axial direction observation of axis 54a, so that looping strand 14 is leaving partially It meets after transfer roller 59 with first circulation strand 52a.

A kind of similar plan of establishment of imagination is that second guide 60 includes guide reel 64, rotation axis 64a, has The circulation roller 66, angle biasing or the angular distance 68 that recycle axis 66a, b, c, d, e, f and the deflection roll 69 with clinoid 69a Situation.Clinoid 59a, 69a are positioned according to angle of twist as described above.

As shown in fig. 6, a kind of advantageous plan of establishment includes the fact that the guide reel 54 of first guide 50 and follows The respective rotation axis of ring roll 56 is set as in 90 ° with the guide reel of second guide 60 and the circulation respective rotation axis of roller Angle.But it is similar to second embodiment, the other angles between above-mentioned rotation axis are also feasible, such as its range is at 0 ° To between 120 °.The selection of advantageous angle depends on such as those listed factor in a second embodiment.

In order to relative to the angular distance 58 between the rotation axis 54a or 64a of guide reel 54 or 64 setting adjacent circulation roller Or 68, it can be envisaged that the circulation axis 66a-f of rotation axis 56a-h or circulation roller surrounds the rotation of respective guide roller 54,64 Shaft axis is arranged along circular arc, and can for example be replaced or consolidate in groove 58a, 68a of circular shape in the right way It is fixed.The quantity for recycling strand as a result, can change and be adjusted for corresponding application.

It specifically, can be by changing angle of twist of the angular distance 58,68 to influence.

Each circulation roller 56,66 be arranged to corresponding rotation axis 54a, 64a of guide reel 54,64 be separated by it is specified away from From, wherein advantageously the distance is all identical for all circulation rollers.But it is possible to which it is envisaged that each recycle the upper of roller Stating distance can be different, and/or can be modified for individual or all circulation rollers.

As shown in fig. 7, based on (first) guide device 50 ' modified the first guide 50 according to Fig. 6, deflection Roller 59,69 can be by deflection circulation strand 59c substitution, rotation axis 54a of the corresponding circulation roller 59d relative to guide reel 54 Setting is set in Angle Position appropriate.In the case, looping strand 14 is followed in the deflection circulation strand 59c and first of guide device It is run between ring strand 52a.
