In sliding bearing chamber 13, from the inner, be provided with the two-direction thrust bearing 20, dish spring support ring 19, disk spring group 18 and the disc spring sleeve 15 that are sleeved on successively on pull bar 17, disk spring group 18 is contained in disc spring sleeve 15, disc spring sleeve is bowl-type, the bottom of bowl is sleeved on pull bar, and disc spring sleeve 15 is positioned at the outside of two-direction thrust bearing 20 and opening towards two-direction thrust bearing 20; The outer end of pull bar 17 passes the bottom of disc spring sleeve 15 and is provided with one section external screw thread, is connected with nut 16 on the screw thread of pull bar outer end, the bottom outside adjacency of nut 16 and disc spring sleeve 15.

Disk spring group 18 is comprised of some disk springs, and cramping is between the bottom and dish spring support ring 19 of disc spring sleeve 15, and the bottom inside of the outside and disc spring sleeve 15 is adjacent, and the inboard outside with dish spring support ring 19 is adjacent.Disk spring group 18 and disc spring sleeve 15 all are sleeved on the optical axis part of pull bar 17 screw thread inboards, outer end.Dish spring support ring 19 is an endless member that inside and outside two sides are parallel, between disk spring group 18 and the first inner ring sleeve 21.Certainly, the opening direction of disc spring sleeve also can be reverse, and dish spring support ring is positioned at the outside of disk spring group, and with the nut adjacency, during rotating nut, nut promotes dish spring support ring and compresses dish-shaped groups of springs.

The inner ring of two-direction thrust bearing 20 is arranged between the first inner ring sleeve 21 and the second inner ring sleeve 22.The first inner ring sleeve 21 be sleeved on pull bar 17 in the mode that can axially outwards slide along pull bar 17, and between pull bar 17, be larger matched in clearance, causes unnecessary wearing and tearing to avoid the first inner ring sleeve 21 and pull bar 17 to come in contact.The second inner ring sleeve 22 suits are fixed on the first inner ring sleeve 21.The Outboard Sections of the first inner ring sleeve 21 outer walls is provided with second shaft shoulder 94, and this second shaft shoulder props up the outside of two-direction thrust bearing 20 inner rings, and the lateral surface of the second inner ring sleeve 22 props up the inboard of two-direction thrust bearing 20 inner rings.The outer ring of two-direction thrust bearing 20 is arranged in sliding bearing chamber 13, and 13 outer end, sliding bearing chamber is connected with bearing (ball) cover 14 by bolt, and this bearing (ball) cover 14 is a tubular construction, and the outer end of tubular is provided with flange, for the outer face with the sliding bearing chamber, is connected; The inner of tubular props up the outer ring, the outside of two-direction thrust bearing 20, for the location of this outer ring.

Disc spring sleeve 15 is positioned at the tubular construction of bearing (ball) cover 14, and does not contact with the tubular construction inwall of bearing (ball) cover 14.

Also be provided with a circlip for shaft 23 on pull bar 17, circlip 23 is positioned at the inboard of the first inner ring sleeve 21 and the second inner ring sleeve 22, for promoting the first inner ring sleeve 21 and the second inner ring sleeve 22.Before each material loading, pull bar is extrapolated, make the support reduction device outwards move, and then close up to facilitate upper volume by swelling connecting rod drive swelling watt, because required thrust is little, so be provided with a circlip for shaft 23 on pull bar, the inboard that the installation site of this circlip for shaft 23 is swelling watt first inner ring sleeve 21 while strutting fully.When pull bar 17 moves laterally, circlip 23 promotes two-direction thrust bearing 20 by the first inner ring sleeve 21 and the second inner ring sleeve 22, two-direction thrust bearing 20 promotes sliding bearing chamber 13 by bearing (ball) cover 14, make to move outside sliding bearing chamber 13, outwards move the lower end that drives swelling connecting rod 10, swelling connecting rod 10 pulls swelling watt 7 downward translations, completes closing up of swelling watt, so that the smooth installation of steel coil strip.

When pull bar 17 moves to the inside, the nut 16 be threaded connection in its end promotes disc spring sleeve 15, disc spring sleeve 15 by force transmission on disk spring group 18, the stressed contraction of disk spring group 18, by active force, by dish spring support ring 19, be delivered on the first inner ring sleeve 21 be connected with two-direction thrust bearing 20, the first inner ring sleeve 21 passes to sliding bearing chamber 13 by two-direction thrust bearing 20 by power, move to the inside sliding bearing chamber 13, the lower end that drives swelling connecting rod 10 moves inward, swelling connecting rod 10 promote swellings watts 7 upwards translation open, complete the swelling process of material volume.

The length of above-mentioned disc spring sleeve 15 should guarantee when butterfly spring group 18 does not stress fully, distance between the bottom inside of disc spring sleeve 15 and two-direction thrust bearing 20 is greater than the decrement of butterfly spring, in order to avoid butterfly spring group 18 contacts with two-direction thrust bearing 20 because of disc spring sleeve 15 when compression, the problem that butterfly spring group 18 can't continue compression occurs.

The supporting structure of above-mentioned turnbarrel 27 is selected single thrust bearing, select the structure of two-direction thrust bearing in support and contracting mechanism, because in actual production process, swelling watt can not swelling be arrived angle as shown in Figure 1, can only swelling arrive the position as shown in the first half as left as Fig. 6 b, the size that this part means is the theoretical internal diameter of material volume.If swelling is to the angle shown in Fig. 1, support link is vertical with the axis of pull bar 17, and swelling watt swelling is to full-size so.When the internal diameter size of steel coil strip is greater than theoretical size, that swelling watt just can't the swelling steel coil strip or has been tied with the inner tube of a tyre paper web of steel band.So in fact swelling watt can not swelling arrive full-size, should keep an angle that is less than 90 ° with axis, like this for the weight of bearing steel coil strip and innermost layer steel band or paper web are maintained to enough frictional force, support link and swelling connecting rod just produce an axial force to corresponding gusset, and be delivered on sliding bearing chamber 13 and turnbarrel 27, make the two that relative trend expanded outwardly be arranged respectively, therefore all should adopt thrust bearing for this trend in the supporting structure of turnbarrel 27 and in support and contracting mechanism, this thrust bearing can bear the axial force that this trend produces.Again because, when the thrust bearing in support and contracting mechanism also will bear pull bar and outwards moves, the second inner ring sleeve 22 imposes on its outside active force, therefore in support and contracting mechanism, the thrust axis in sliding bearing chamber 13 is promised and is adopted the two-direction thrust bearing that can bear bi-directional axial load, and the block bearing employing single thrust bearing of turnbarrel 27 gets final product.

The present embodiment is not limited to the said structure form to the installation form of above-mentioned two-direction thrust bearing 20 and the force transferring structure of pull bar 17, also can adopt other mounting structure and force transferring structure, refer to Fig. 7, pull bar 17 is provided with the inboard that is positioned at the inner ring of two-direction thrust bearing 20 for outside the 6th shaft shoulder 172, the six shaft shoulders that promote two-direction thrust bearing 20.The 6th shaft shoulder has directly substituted the second inner ring sleeve be arranged on the first inner ring sleeve, and for holding out against the circlip for shaft of the first inner ring sleeve and the second inner ring sleeve.Also can cancel dish spring support ring 19, disk spring group 18 directly acts on elastic force on the outer face of the first inner ring sleeve 21.

In the present embodiment, start cylinder 33 has two groups, and every group has two.Refer to Fig. 1 and Fig. 5, for the start cylinder cylinder bar that drives the left side pull bar, stretch out to the right, for driving the start cylinder cylinder bar of right side pull bar to stretch out left, be arranged on left side vertical plate for the start cylinder afterbody that drives the left side pull bar, for the start cylinder afterbody that drives the right side pull bar, be arranged on the right side riser.Two groups of four start cylinders 33 are arranged in casing alternately, become two cylinders of a group on a pair of linea angulata, the cylinder bar all stretches out towards the pull bar direction away from by its drive, and hinged with the two side arms top of the horizontally disposed V font of center line connecting plate 35, the bottom of V font connecting plate 35 is connected with pull bar 17.

Refer to Fig. 1, Fig. 5, the cylinder bar of start cylinder 33 is hinged with the side arm end of V font connecting plate 35 by connector 36.Correspondingly, the side arm of the V font connecting plate 35 of arm structure both sides is arranged in a crossed manner, two connecting plates 35 are mutually vertical, in the space of the V font inside bottom of each connecting plate 35 between the V of another connecting plate 35 font two side arms, utilize space between each V font two side arms to hold the bottom of another connecting plate and connection wye 34 hinged, that be positioned at tie rod end with it, this connection wye 34 is threaded in the inner end of pull bar 17.When so the size of connecting plate should guarantee that start cylinder bar is released, the bottom of two V fonts can not interfere, and simultaneously the width between V font two side arms should be greater than the thickness of connecting plate and for the length of the bearing pin of the Y-shaped connector 34 of hinged V font connecting plate bottom and tie rod end.

Connection wye 34 is threaded in the inner end of pull bar 17, and connection wye 34 adopts the locking nut locking be connected on pull bar 17, installs stop washer (GB/T858-1988) between locking nut and Y-shaped connector additional, can limit the rotation of connection wye with respect to pull bar.In other words, owing to being that plane is hinged between connection wye and connecting plate, and connecting plate can not rotate, thus connection wye also can not rotate, so also just limited the rotation of pull bar.

Because exoskeletal accurate after-combustion steel coil strip is different from the wide cut steel coil strip, it is even more that wide cut steel coil strip width can reach the 1m left and right, and the width of wall scroll steel band and the Thickness Ratio of steel coil strip are larger, are not prone to the problem that steel band scatters to side.And, for the flux-cored wire steel coil strip, width of steel band is 10～20mm, in arbitrary section, one deck steel band generally has the steel band more than 20, and the probability that such steel coil strip generation is scattered to side is more much bigger than wide cut steel coil strip.So need to baffle plate be set in the steel coil strip both sides, in case the steel band in steel coil strip scatters to side.

Refer to Fig. 1, in order to prevent the inside side of steel band in steel coil strip, scatter, be provided with Internal baffle assembly 2 on drive socket 28, drive socket 28 is packed in the outside of turnbarrel 27, the Internal baffle assembly is packed in the outside of drive socket 28, drive socket 28 outer ends are provided with for locating the shaft shoulder of Internal baffle assembly inboard, and the outside of Internal baffle assembly is held out against by Internal baffle locating ring 29, Internal baffle locating ring 29 by screw fastening on drive socket 28.

Due to exoskeletal accurate after-combustion steel coil strip on being lifted into uncoiler the time, can not directly the side of steel coil strip be against on the rectangular steel tube of Internal baffle assembly, because along with the radial direction of swelling watt is outside, axial direction is to the movement of machine intimate, the movement locus of steel coil strip and the swelling that it is propped up are watt the same, one-component can be arranged in the axial direction, if directly the side of steel coil strip is against on the rectangular steel tube of Internal baffle assembly, between steel coil strip and swelling watt, relative motion can occur, and the frictional force of relative motion is larger, the inner end edge of swelling watt is likely destroyed interior one deck or which floor steel band, cause whole steel coil strip to be subsided.So can not directly make of the Internal baffle assembly axial direction positioning device of steel belt for lifting volume.When steel belt for lifting is rolled up, steel coil strip need to be placed on to swelling watt upper, now just need in swelling watt, a location device be arranged, with the control steel coil strip in axial position.

Refer to Fig. 1, in the present embodiment, swelling watt inner reinforced plate 8 is provided with inboard positioner 37, and inboard positioner is arranged on the end of swelling watt gusset near casing.Inboard positioner comprises two connection boards that are arranged on swelling watt inner reinforced plate both sides, connection board is L shaped, horizontal bottom is as the connecting portion with swelling watt link of boards, vertical portion is as location division, the connecting portion of connection board is provided with horizontal slotted hole, be provided with the dog screw of connection board in horizontal slotted hole, dog screw is fixed together connection board and a swelling watt gusset.Control the horizontal relative position of itself and dog screw by moving horizontally connection board, can adjust the relative position of inboard positioner and swelling watt, guarantee that steel coil strip is after fully by swelling, its inside edge can contact with the square tube of Internal baffle assembly, realizes the location of steel band.

Refer to Fig. 3, Fig. 4 a and Fig. 4 b, locate in like manner with inboard, the arranged outside of uncoiler has outside positioner, and outside positioner is demountable structure.Outside positioner comprises steel band outer baffle and outer baffle positioner; The steel band outer baffle comprises outer ring 381, inner ring 383 and the spoke 382 that is connected outer ring and inner ring, and above part forms by metal tube.The outer baffle positioner comprises two guide posts 392 and two abutment sleeves 385; Two abutment sleeve 385 disalignments, all be horizontally disposed with, and the length of one of them abutment sleeve is greater than another abutment sleeve, and two abutment sleeves 385 respectively are connected with the inner ring 383 of outer baffle by backstay 384; Two guide posts 392 respectively are fixed on the outer circumference surface of turnbarrel 27 by riser 391, and two guide posts 392 are installed on respectively in two abutment sleeves 385, and the end of guide post 392 is provided with screw thread, and a setscrew nut has been threaded on screw thread.By two point locations and a line location, can limit the axial location of outer baffle device, and can limit the outer baffle swing like this.

In the present embodiment, the syndeton of casing and base, similar with disclosed syndeton in patent documentation CN201525655U, the present invention does not repeat them here.

As shown in Fig. 6 a～Fig. 6 b and Fig. 1, the operation principle of the present embodiment is:

One) as shown in Fig. 6 a the first half, before the steel belt for lifting volume, the start cylinder group of respective side is shunk, the start cylinder drives pull bar by connecting plate and stretches out, circlip for shaft on pull bar promotes the first inner ring sleeve and the second inner ring sleeve, the second inner ring sleeve promotes the inner ring of two-direction thrust bearing, and promotes bearing (ball) cover by two-direction thrust bearing.Because bearing (ball) cover and sliding bearing chamber are connected, the sliding bearing chamber is also along with bearing (ball) cover outwards moves together, the outdoor gusset of sliding bearing be packed on the sliding bearing chamber also outwards moves thereupon together, angle between swelling connecting rod and axis reduces, angle between support link and axis reduces simultaneously, the circular arc that the distance of take between two pin joints of support link and swelling connecting rod in swelling watt edge is radius outwards moves, and the external diameter of swelling simultaneously watt also dwindles thereupon.When the outer gusset of the inner reinforced plate of swelling watt and turnbarrel contacts, the external diameter of swelling watt is retracted to minimum of a value, and now the start cylinder still may not shrink and put in place.

Because the axial location of inboard positioner on swelling watt gusset can be regulated, so, before the steel belt for lifting volume, need to adjust the position of determining inboard positioner.If directly steel coil strip is placed in swelling watt, the standard of neither one location, the workman determines the position of steel coil strip entirely by rule of thumb, so very possible bigger than normal or less than normal, if steel coil strip is excessively near apart from outer end, will cause swelling watt after swelling, the inboard of steel coil strip still can't touch on the square tube of Internal baffle, steel coil strip does not have the location, side, and the steel band kept to the side most still likely subsides.If inboard positioner is excessively far away apart from outer end, although can utilize the square tube of Internal baffle accurately locates the side of steel coil strip, but can increase the distance of the friction of steel coil strip and swelling watt support, for the steel coil strip that there is no paper web, this is by the most inboard steel strip surface in the heavy wear steel coil strip, and wire feed when administration core welding wire is produced follow-up drawing work or use brings difficulty; For the steel coil strip that has paper web as the inner tube of a tyre, although there is not the problem of wearing and tearing steel strip surface, also can strengthen the wearing and tearing to recycled paper web.And, except wear problem, when steel coil strip and swelling watt relatively move, frictional force needs the active force of start cylinder to overcome, and certainly can increase the load of start cylinder, likely causes the increase of start cylinder size.After having increased inboard positioner, can be after once adjusting to the right place, it is carried out fastening, during each upper volume, just had one reproducible, the position reference of accurate positioning, without again adjusting, can avoid above-mentioned problem.

Two) after steel coil strip being placed in to the upper and axial location of swelling watt, the start cylinder stretches out, and the connector on start cylinder bar drives connecting plate, and then drives pull bar and retract, and the nut of tie rod end compresses disc spring sleeve, disc spring sleeve compression butterfly spring group.Because the butterfly spring group is not little when decrement will be more than the lifting steel coil strip in other words in compressive state when pull bar stretches out fully, so now the start cylinder is only to compress the butterfly spring group by pull bar, and do not cause other variations, for example can suppose that now the distance between dish spring support ring and first shaft shoulder is 5mm, now state is as shown in the lower part of Fig. 6 a.Certainly, if in order to reduce space in casing and the start cylinder of selection of small stroke, can cause the start cylinder to shrink swelling watt inner reinforced plate while putting in place still is suspended from the outer gusset of turnbarrel, both can not dock, if will expect that in this case volume is placed in swelling watt, can move sliding bearing is outdoor by the swelling connecting rod, by two-direction thrust bearing, the first inner ring sleeve, dish spring support ring, force transmission, on the disk spring group, be compressed the disk spring group.Certainly be likely also above the two combination, be the swelling watt inner reinforced plate segment distance that descends, by after one section of disk spring group compression, swelling watt inner reinforced plate falls to being placed on the outer gusset of turnbarrel, when then pull bar moves inward, then the disk spring group is continued to one section of compression.

On the butterfly spring group, suffered compression stress reaches in the time of steel coil strip need to being risen to required active force, the sliding bearing chamber is (this power is delivered on the sliding bearing chamber by dish spring support ring and two-direction thrust bearing) under the elastic force effect of butterfly spring, in turnbarrel, move, and then by swelling connecting rod and support link, swelling watt is propped up, now the center of gravity of steel coil strip is constantly rising.

Angle when while putting in place due to swelling watt swelling, swelling connecting rod and support link are greater than these two connecting rods and have just started the lifting steel coil strip with respect to the angle of axis, so stressed (butterfly spring stressed) during swelling on connecting rod is less than the power while just starting the lifting steel coil strip, the length of butterfly spring is greater than its length when just starting the lifting steel coil strip, in lifting the process of steel coil strip, butterfly spring is in fact to discharge its decrement constantly, now the distance between dish spring support ring and first shaft shoulder is 1.5mm, now state is as shown in the first half of Fig. 6 b.Now the disk spring group still has certain compression surplus.So watt by steel coil strip after complete swelling, the start cylinder still continues to release a segment distance in swelling, pull bar continues to shrink inwards, disc spring sleeve compression butterfly spring group.Until reach start cylinder stroke, the lock of locking start cylinder interior is locked the start cylinder, prevents that the start cylinder from losing thrust because of gas leakage, the accident that causes the material volume to fly out, now the distance between dish spring support ring and first shaft shoulder is 3.5mm, and now state is as shown in the latter half of Fig. 6 b.Be butterfly spring by the length of another compression in the swelling watt length that after complete swelling, start cylinder bar continues to stretch out by steel coil strip, this length is 2mm.When the parts such as start cylinder, connecting plate, connector, pull bar are installed more accurately, this length is needed just less, and the second-compressed amount of spring is also just less, and pressure during final uncoiler operation on the disk spring group is also just less.For above-mentioned reasons, in uncoiler when operation,, in other words, the axial force after the steel coil strip swelling is less, and after machine run gets up, the two-direction thrust bearing in the outside and inboard thrust bearing stressed also less, be conducive to improve the thrust bearing life-span.

The generation of second-compressed amount is not only in order to make up the error while installing, and has the effect that tension force is provided concurrently.Because in the process in fact constantly strutted in swelling watt, swelling watt is only also the gravity that equals the material volume for the holding power of material volume, now the elastic force on butterfly spring also with this holding power to corresponding.If there is no second-compressed, that swelling watt will be the same (due to the geometrical relationship between swelling connecting rod, swelling watt, support link and pull bar with not using the disk spring group to the tension force of material volume, can not produce larger tension force, otherwise will cause structural damage) use so the advantage of disk spring group to give prominence to.And the generation of this second-compressed amount, over against the generation of having answered additional tension force, and this tension force can not disappear because of the gas leakage/leakage of start cylinder, and this additional tension force exactly, guaranteeing can have enough frictional force between swelling watt and material volume the most inboard (or material roll up paper web), control raising speed/reduction of speed that the honest material convolution turns etc., improved the safety and reliability of system.For example, the weight of material volume is 1000 kilograms, when swelling watt will be expected the complete swelling of volume, active force on the disk spring group is 800 kgfs, second-compressed due to the disk spring group, active force on the disk spring group has increased again by 320 kgfs, has increased again so the tension force of 400 kgfs between swelling watt and material volume inboard, and this has just increased swelling watt and has rolled up the frictional force between inboard with material.

Because the uncoiler or the winder that adopt swelling watt distensible material volume inner core are different from I-beam wheel unwinding and rewinding machine.The material of I-beam wheel unwinding and rewinding machine volume is placed on I-beam wheel (or being referred to as drum), and the rotary speed of I-beam wheel is to embed in the hole in I-beam wheel by the finger on the unwinding and rewinding machine, stirs I-beam wheel and rotates to regulate its rotating speed.And the frictional force that the rotating speed that adopts the confidential adjusting material volume of material retractable of swelling watt can only be rolled up between inner core by swelling watt and material is regulated its rotating speed, and frictional force is determined by tension force and coefficient of friction, and coefficient of friction be immobilize moving, so can only improve frictional force by increasing tension force.

Once the piston movement of self-locking cylinder puts in place, the active force that the cylinder of the uncoiler of the existing form of employing externally applies is and overcomes the required corresponding dish spring force of holding power of material volume weight, and for example the piston area of cylinder is 314cm ², air pressure is 4kgf/cm ², the power that cylinder can externally apply in theory is 1256kgf, but in fact after self-locking, can only externally apply 800kgf, remaining 1256-800=456kgf can only act on the cylinder bottom of cylinder.For example the coefficient of friction between tensioner watt and material volume is 0.3, and the frictional force of now every swelling watt can only be 300kgf.If tensioner puts in place before self-locking, cylinder no longer moves, and cylinder on the contrary can outwards be exported the 1256kgf active force, but there is no self-locking, once cylinder leakage tester will be easy to occur the accident that the material volume flies out.

But after the present invention has increased butterfly spring, butterfly spring can also carry out second-compressed, and swelling watt can increase extra tension force again, for example increase mentioned above the tension force of 400kgf, and this swelling watt total can increase the frictional force of 120kgf again.And the technical scheme in employing the present embodiment, raising tension force that can be larger, and then improve the unwinding and rewinding machine that adopts swelling watt form and material is rolled up to the control ability of velocity variations, the acceleration that in the time of can adapting to speed governing, needs are larger and/or material are rolled up the larger occasion of rotary inertia, have expanded the scope of application of such machine.

Three) after swelling has operated; outer baffle is contained in swelling watt; utilize two abutment sleeves and two guide posts to realize the location to outer baffle; wherein two abutment sleeves have completed point location jointly; longer abutment sleeve has also completed and has prevented the location swung; then use nut check, can play the protective effect to the outer side edges of steel coil strip.

After completing the location, the outside of steel coil strip, can start the passive band of putting.

Disk spring group in the present embodiment also can be replaced by the elasticity of compression parts of other type, other compressibility springs of mentioning in the 11st piece of spring chapter 1 spring of Chemical Industry Press's version " mechanical design handbook " the 3rd volume in 2002 that can edit referring to Cheng great Xian, resilient sleeve for example, cylindroid helical-coil compression spring etc.Nut 16 can be by the limited block of pin joint or by the alignment pin replacement of pull bar axis.

Most of identical with embodiment 1, just changed the connected mode of start cylinder and pull bar.Stretch by the start cylinder contraction that realizes pull bar in embodiment 1, in the present embodiment, shrink the contraction realize pull bar by the start cylinder.

Refer to Fig. 9, the pull bar in left side of take is example, driving the start cylinder 33 of pull bar 17 is also two one group, but different is, and the cylinder bar (approaches the direction of connected pull bar outer end) towards left side stretches out, and the end of each start cylinder cylinder bar is also to be connected with a side arm end of V-arrangement connecting plate 35 by a connector 36.Different: the connecting plate in the connecting plate Length Ratio embodiment 1 in the present embodiment is short, and opening direction is different from embodiment 1, the top of V-arrangement connecting plate 35 approaches the outer end of connected pull bar 17 than its bottom in the present embodiment, at the bottom of two V-arrangement connecting plates that therefore are connected with two groups of pull bar start cylinders respectively, dolly is directly arranged.35 of connecting plates being responsible for push-and-pull left side pull bar move in left zone at the machine center line, the connecting plate of being responsible for push-and-pull right side pull bar only moves in right zone at the machine center line, the inner bottom part of V font connecting plate is relative and hinged with the breeches joint on pull bar, be in the space between the two side arms of breeches joint 34 in V font connecting plate on pull bar, the distance between V font connecting plate 35 two side arms should be greater than the width of connection wye.

The present embodiment also provides the syndeton of another kind of start cylinder cylinder bar and pull bar:

Referring to Figure 10 a, the pull bar in left side of still take is example, and the start cylinder 33 cylinder bars that drive pull bar to move also stretch out towards left side, but start cylinder 33 cylinder bars are different from the connected mode of pull bar 17 the inners.In Figure 11, be provided with the connecting plate vertical with them 46 for the cylinder bar of the start cylinder group that drives pull bar 17, pull bar 17 is connected with U-shaped latch fitting 48 by branch sleeve 47 with the middle part of connecting plate 46.Branch sleeve 47 is arranged on the inboard of connecting plate 46, and the middle inside of branch sleeve 47 is provided with a gap; Be provided with two stopper slots with the parallel adaptation of above-mentioned gap in the inner end cylindrical both sides of pull bar, the lateral surface of stopper slot is inclined-plane; U-shaped latch fitting 48 is inserted in the stopper slot of pull bar 17, inside and outside both sides are by the madial wall cramping of gap bottom surface and stopper slot, the side arm cramping of U-shaped latch fitting 48 is between at the bottom of gap wall and stopper slot, the side arm of U-shaped latch fitting 48 is provided with the inclined-plane with the inclined-plane adaptation of stopper slot, the angle on this inclined-plane should be in the friction self-locking scope, can guarantee that the U-shaped latch fitting can not deviate from.The structure that U-shaped latch fitting 48 is inserted in the inboard gap of branch sleeve can also prevent that pull bar from rotating.

The 3rd start cylinder cylinder bar that the present embodiment provides and the syndeton of pull bar, refer to Figure 10 b, the pull bar 17 in left side of still take is example, the start cylinder 33 cylinder bars that drive pull bar to move stretch out towards left side, be provided with the connecting plate vertical with them 46 for the cylinder bar of start cylinder group that drives pull bar 17, the outer middle side part of connecting plate 46 is provided with contiguous block 49, and contiguous block 49 is provided with T-shaped groove; The inner end of pull bar is provided with the protuberance that radius is greater than its adjacent part, and protuberance is contained in T-shaped groove.The direction of T-shaped groove is 45 ° with the direction of the paired start cylinder cylinder bar line of centres.

Embodiment 3:

The present embodiment and above-described embodiment difference are:

The first structure: refer to Fig. 1 and Figure 11 a, the afterbody of each start cylinder all is hinged on the riser of casing, and the cylinder bar is connected with the inner of pull bar 17 by a lever 35.The inner of pull bar 17 is connected with the first Y-shaped connector 34, start cylinder cylinder club head is equipped with the second Y-shaped connector 36, the two ends of lever 35 are hinged with the first Y-shaped connector 34 and the second Y-shaped connector 36 respectively, with the hinged part of the first Y-shaped connector, be wherein the elongated slot non-circular hole, the middle part of lever 35, with to be fixed in casing riser upper bracket 63 hinged, is connected with casing riser and the 17 homonymy settings of driven pull bar of bearing 63.

The second structure: refer to Figure 11 b, form the second structure that two start cylinders 33 of a group are connected with pull bar: be with the difference of above-mentioned the first structure, the afterbody of start cylinder 33 is directly installed on the riser of casing, lever 35 is for the first Y-shaped connector 34 with the hinged junction, end of the second Y-shaped connector 36 should be elongated slot and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".

Below 2 kinds of leverages different from above two kinds of leverages, changed the connected mode of start cylinder and pull bar.In embodiment 1, by the contraction that realizes pull bar of stretching of start cylinder cylinder bar, in the present embodiment, contraction by start cylinder cylinder bar realizes the contraction of pull bar.

The 3rd kind of structure: refer to Figure 12 a, with the difference of the first structure in embodiment 4, be: the middle part of lever 35 and the first Y-shaped connector 34 are hinged, one end of lever 35 and the second Y-shaped connector 36 are hinged, with the hinged part of the first Y-shaped connector, be wherein the elongated slot non-circular hole, the other end of lever 35 is hinged with the bearing 63 be fixed on the casing riser, and bearing 63 and start cylinder are located at the both sides of pull bar 17 in 33 minutes.When the start cylinder stretches out, pull bar is side shifting outside casing, and a swelling watt radius is reduced; When the start cylinder shrinks, pull bar moves to box house, makes swelling watt spreading to setting diameter.

The 4th kind of structure: refer to Figure 12 b, with the difference of above-mentioned the first structure, be, the afterbody of start cylinder 33 is directly installed on the riser of casing, cylinder bar 35 is for the hinged junction, end of the first Y-shaped connector 34 with the hinged junction, middle part of the second Y-shaped connector 36, should be elongated slot and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".

The 5th kind of structure: by the tail end of pull bar, an end that is positioned at casing is made a sleeve with internal thread, and the internal thread of sleeve directly is connected with the piston rod of cylinder, and this kind of structure is comparatively simple, without accompanying drawing, describes.

Embodiment 4:

Be the positioner of outer baffle with the difference of above-described embodiment.Refer to Figure 13 a and Figure 13 b, in the present embodiment, the positioner of outer baffle comprises and is sleeved on the outer locking of swelling watt watts 53, be connected with the holding screw and the backstay 54 that are pressed in swelling watt in locking watts 53, backstay slides and is installed in spoke 56 through outer baffle inner ring 55, radially be provided with slotted hole 561 on spoke, be provided with the lock-screw affixed with backstay in slotted hole.Locking watt compresses swelling watt by the holding screw on it and realizes locking, and backstay compresses spoke by the lock-screw on it and realizes location.

Above-mentioned outer baffle positioner, can avoid the large problem of embodiment 1 outer baffle positioner difficulty of processing.Because, in embodiment 1, outer baffle and turnbarrel are except the nested relationship of abutment sleeve and guide post, two incoherent parts fully, and overcoat has the outer baffle guide post of abutment sleeve still to be welded on turnbarrel by riser, through this hot-working of welding, total just more likely produces new error because expand with heat and contract with cold, reduce the quality of fit of abutment sleeve and outer baffle guide post, increasing fit clearance needs to guarantee to install, thus, improved the unstability of outer baffle location; The raising machining accuracy, increase processing cost.The two scheme has certain drawback.

Outer baffle positioner in embodiment 1, because the end at riser is provided with the outer baffle guide post, once guide post is stressed, for riser, it is a cantilever beam structure of only having fixed at afterbody, and outer baffle guide post itself is also a cantilever beam structure of only having fixed at afterbody, this structure is very unfavorable for carrying.In order to reduce the negative effect of riser cantilever beam structure, can reduce the height of riser, if but reduce height, just need to increase the length of backstay in the outer baffle positioner, and backstay itself is also a cantilever beam structure, if increase the length of backstay, certainly will reduce its rigidity and bearing capacity again.And outer baffle is after being put on uncoiler by the material volume, be manually installed on uncoiler, in order to reduce workman's work load, what need again as much as possible outer baffle to be done is lighter, so its material is also selected the material that density is less, intensity is poor or wall thickness is thinner, so that its rigidity is not easy to do again is too much.The two has just formed contradiction.

The present embodiment, the positioner of outer baffle is changed into to the locking watt directly be sleeved in swelling watt, locking watt shape and size and swelling watt coupling, no matter how a swelling watt formed circular outer diameter size changes, the shape of swelling watt itself is fixed, so locking watt can realize stable coordinating with swelling watt.And the variation of swelling watt external diameter is to make up by adjusting the position of backstay in spoke during swelling.The present embodiment by holding screw compress swelling watt realize locking watt location, simple in structure, easy to operate.

In the present embodiment, the steel band outer baffle adopts plectane to add the structure that spoke adds inner ring, and the effect of spoke is equivalent to gusset.The steel band outer baffle also can adopt the structure of outer ring+spoke in embodiment 1+inner ring.

Embodiment 5:

Refer to Fig. 8, and the difference of above-described embodiment is: clamp and adjust packing ring 60, adjust packing ring 60 and be sleeved on pull bar 17 between first shaft shoulder of dish spring support ring 19 and pull bar.Dish spring support ring 19 does not directly contact with first shaft shoulder 171 of pull bar, but contact with the adjustment packing ring 60 for size adjusting, the internal diameter of adjusting packing ring 60 is identical with the external diameter of pull bar 17, the external diameter of adjusting packing ring 60 is identical with the internal diameter of the first inner ring sleeve 21, and can be endwisely slipped between the first inner ring sleeve 21.

In process of production, the internal diameter of steel band material volume can not be completely unified, and the present invention depends on the locking start cylinder that pulls pull bar and can move fully and put in place, utilizes lock in the start cylinder to guarantee not occur the material volume accident that flies out.But the position that material volume internal diameter and pull bar pull is to have certain relation of interdependence, if the internal diameter of material volume is larger than theoretical value, after putting in place, the start cylinder cylinder bar that causes driving pull bar still can't increase to position, also can't guarantee even again discharge decrement by butterfly spring, so just need to adjust the relative position of dish spring support ring and pull bar.For example, the position of dish spring support ring is outwards moved, need increase to adjust thickness or the quantity of packing ring, make the start cylinder when moving to terminal, the external diameter of swelling watt is less than original steel coil strip internal diameter; Vice versa.Adjust packing ring various ways can be arranged: 1) for certain material volume internal diameter size, calculate the every increase certain size of internal diameter (for example 1mm or 0.5mm), the thickness of needed adjustment packing ring, each adjusts the internal diameter of corresponding a kind of material volume of thickness of packing ring, when the internal diameter of steel coil strip changes to some extent, increase or reduce corresponding adjustment packing ring number; The size of required size adjusting packing ring when 2) calculating respectively discharging volume internal diameter and be different size, make respectively the adjustment packing ring of coil diameter in corresponding each steel band, when the internal diameter of steel coil strip changes to some extent, and integral replacing size adjusting packing ring.

Embodiment 6:

In above-described embodiment, swelling watts 7 is connected by the outdoor gusset 12 of swelling watt inner reinforced plate 8 and swelling connecting rod 10 and sliding bearing, swelling connecting rod one end and the outdoor gusset of sliding bearing plane are hinged, the other end and swelling watt inner reinforced plate plane is hinged, and the outdoor gusset of sliding bearing and sliding bearing chamber are connected, swelling watt inner reinforced plate and swelling watt are connected.Under the constraint that there is no other, in the swelling plane of movement of swelling watt, the swelling connecting rod can carry out with respect to the sliding bearing chamber swing of single-degree-of-freedom, and swelling watt can be carried out the swing in plane centered by the hole of swelling interlinking lever end.So take the sliding bearing chamber as coordinate system, swelling watt has two frees degree.So can claim to be connected for 2DOF between swelling watt and sliding bearing chamber.

In like manner, in above-described embodiment, a transverse plane of an end of two groups of support link 9 and swelling watt inner reinforced plate 8 is hinged, and the outer gusset of the other end and turnbarrel 11 planes are hinged.Because two groups of support link are isometric, and two hinged holes of swelling watt inner reinforced plate and two groups of support link are and the outer gusset of turnbarrel and two groups of two holes that support link is hinged, and pitch-row is the same, and this has just formed parallel-crank mechanism.And the swelling watt mode with parallel-crank mechanism connects and turnbarrel, so swelling watt can only, in parallel with turnbarrel all the time mode, under support link and the drive of swelling connecting rod, carry out parallel, and any rotation or swing not occur for self.Its position only is decided by the angle between the outer gusset of support link and turnbarrel, so be connected for single-degree-of-freedom between swelling watt and turnbarrel.

So for 2DOF is connected, and be that 1 free degree is connected between turnbarrel between swelling watt and sliding bearing chamber, so connecting, the M free degree described in summary of the invention is connected with the N free degree, M+N=3 is this concept.

Except the described swelling of above-described embodiment watt bracing or strutting arrangement, can also adopt following method for supporting:

The first mechanism:

As shown in figure 14, this figure is for simplifying view, swelling connecting rod and support link are reduced to straight line, every place hinge hole is reduced to circle, and in figure, the sliding bearing chamber is connected with swelling watt by two groups of isometric swelling connecting rods, and two hinged holes of swelling watt inner reinforced plate and two groups of support link are and the outdoor gusset of sliding bearing and two groups of two holes that support link is hinged, pitch-row is the same, forms parallel-crank mechanism, so swelling watt is that single-degree-of-freedom is connected with the sliding bearing chamber.And swelling watt is by one group of support link and the outer link of boards of turnbarrel, swelling watt is that 2DOF is connected with turnbarrel.In the breathing plane of movement of every tensioner watt, the described swelling watt mode connected with the M free degree is connected with the sliding bearing chamber, in the mode of N free degree connection, with turnbarrel, is connected, and M is that 1, N is 2, and M+N=3.

In this structure, although the weight of material volume is by tensioner connecting rod and support link shared, be that some radial load is born by the sliding bearing chamber, but as shown in Fig. 1, Fig. 6 a and Fig. 6 b, the sliding bearing chamber is when sliding into maximum distance, still some length is embedded in turnbarrel, and radial load is born by turnbarrel, does not have the problem of utilizing two-direction thrust bearing to bear radial load.

The second mechanism:

As shown in figure 15, be different from Figure 14, the inner of swelling watt is not hinged by support link and inner sleeve gusset, but is connected with turnbarrel by parallel-crank mechanism, swelling watt is connected with single-degree-of-freedom.Can say that this programme is a kind of change example of scheme shown in Figure 14, in the breathing plane of movement of every tensioner watt, the swelling watt mode connected with the M free degree is connected with the sliding bearing chamber, the mode connected with the N free degree is connected with turnbarrel, M is that 1, N is 1, and M+N=2.Although M+N=2.But this is connected and causes with sliding bearing chamber or turnbarrel because swelling watt the inner and outer end all adopt parallel-crank mechanism, in fact this is a kind of constraint of crossing location, if the hypotenuse of the parallel-crank mechanism of both sides---support link and swelling connecting rod are all isometric, arbitrary swelling connecting rod and arbitrary support link and that section swelling between them watt and the turnbarrel between them and sliding bearing chamber length can form isosceles trapezoid, and swelling watt can be moved so.If support link and swelling connecting rod are not isometric, so, this mechanism has in fact just become structure, and swelling watt can't have been moved.

The third mechanism:
