In the present embodiment, start cylinder 33 has two groups, and every group has two.Refer to Fig. 1 and Fig. 5, stretch out to the right for the start cylinder cylinder bar that drives left side pull bar, 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 left side pull bar, be arranged on right side riser for the start cylinder afterbody that drives right side pull bar.Two groups of four start cylinders 33 are arranged in casing alternately, become two cylinders of a group on a pair of linea angulata, and cylinder bar all stretches out towards the pull bar direction away from by its drive, and the piston rod of each cylinder is all by the link of boards of connecting panel and sleeve bearing outside.
Refer to Fig. 1, Fig. 5, the cylinder bar of start cylinder 33 is hinged with the end of connecting panel 35 by connector 36.Two groups arranged in a crossed manner for connecting the connecting panel of every group of cylinder and corresponding sleeve bearing chamber, two groups of connecting panels 35 are mutually vertical, in the each and space between two connecting panels 35 of another group, sleeve bearing chamber that connecting panel 35 is connected, utilize every group of space between two connecting panels to hold another corresponding sleeve bearing chamber that is positioned at tie rod end of group.So when the size of connecting panel should ensure that start cylinder bar is released, the distance between two connecting panels of every group should be greater than the external diameter of sleeve bearing chamber simultaneously.
Because exoskeletal accurate after-combustion steel coil strip is different from wide cut steel coil strip, it is even more that wide cut steel coil strip width can reach 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 flux-cored wire steel coil strip, width of steel band is 10～20mm, in arbitrary section, one deck steel band generally has 20 above steel bands, and it is more much bigger than wide cut steel coil strip that the probability that scatters to side occurs such steel coil strip.So need to baffle plate be set in steel coil strip both sides, in case the steel band in steel coil strip scatters to side.

In the present embodiment, the connection structure of casing and base, similar with disclosed connection structure 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 principle of work of the present embodiment is:
One) as shown in Fig. 6 a the first half, before steel belt for lifting volume, the start cylinder group of respective side is shunk, start cylinder drives sleeve bearing chamber outwards to move by connecting panel, sleeve bearing chamber promotes the inner outer ring of two-direction thrust bearing by the roller bearing end cap being connected with it, two-direction thrust bearing promotes the first inner ring sleeve and the second inner ring sleeve, the circlip for shaft that the first inner ring sleeve and the second inner ring sleeve outwards move by pull bar pushing drawing rod.Because pull bar and slip cap are connected in the axial direction, slip cap is also along with pull bar outwards moves together, the outer gusset of slip cap being packed on slip cap also outwards moves thereupon together, angle between swelling connecting rod and axis reduces, angle between support link and axis reduces simultaneously, outwards move taking the distance between support link and two hinge-points of swelling connecting rod as the circular arc of radius on swelling watt edge, and the external diameter of simultaneously swelling watt also dwindles thereupon.In the time that the inner reinforced plate of swelling watt and the outer gusset of turnbarrel contact, the external diameter of swelling watt is retracted to minimum value, and now start cylinder still may not shrink and put in place.
Because the axial location of inner side registration device on swelling watt gusset can regulate, so before steel belt for lifting volume, need to adjust the position of determining inner side registration device.If directly steel coil strip is placed in swelling watt, the standard of neither one location, 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 inner side of steel coil strip still cannot touch in the square tube of Internal baffle, steel coil strip does not have location, side, and the steel band keeping to the side most still likely subsides.If inner side registration device 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 there is no the steel coil strip of paper web, this is by the steel strip surface of inner side in severe wear steel coil strip, and the wire feed when producing follow-up drawing work or use to flux-cored wire 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, in the time that steel coil strip and swelling watt relatively move, friction force needs the application force of start cylinder to overcome, and certainly can increase the load of start cylinder, likely causes the increase of start cylinder size.Increased after the registration device of inner side, can be after once adjusting to the right place, it is carried out fastening, when each upper volume, just had one reproducible, the position reference of accurate positioning, without again adjusting, can avoid above-mentioned problem.
Two) steel coil strip is placed in after the upper and axial location of swelling watt, start cylinder stretches out, connector on start cylinder bar drives connecting panel, and then drive sleeve bearing chamber to retract, the tight two-direction thrust bearing of sleeve bearing constant pressure, and by two-direction thrust bearing, the first inner ring sleeve, dish spring carrier ring compression belleville spring group.Because belleville spring group is not little when amount of compression will be more than lifting steel coil strip in other words in compressive state in the time that pull bar stretches out completely, so now start cylinder is only to compress belleville 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 start cylinder to shrink swelling watt inner reinforced plate while putting in place is still suspended from the outer gusset of turnbarrel, both do not contact, if in this case material volume is placed in swelling watt, can slip cap be moved outward by swelling connecting rod, the nut by slip cap, pull bar and pull bar the inner on dish spring group, compresses force transmission by dish spring group.Certainly be likely also above the two combination, i.e. the swelling watt inner reinforced plate segment distance that declines, by after one section of dish 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 dish spring group is continued to one section of compression.
When compressive force suffered in belleville spring group reaches steel coil strip need to be risen to required application force time, pull bar is under the elastic force effect of belleville spring, inner mobile to turnbarrel, 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 swelling connecting rod and support link are greater than these two connecting rods and have just started lifting steel coil strip with respect to the angle of axis while putting in place due to swelling watt swelling, so stressed (belleville spring stressed) when swelling on connecting rod is less than the power while just starting lifting steel coil strip, the length of belleville spring is greater than its length in the time just starting lifting steel coil strip, in the process of lifting steel coil strip, belleville spring is in fact to discharge its amount of compression 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 dish spring group still has certain compression surplus.So watt by after complete steel coil strip swelling, start cylinder still continues to release a segment distance in swelling, pull bar continues to shrink inwards, dish spring support ring compression belleville spring group.Until reach start cylinder stroke, the lock of locking start cylinder interior is locked start cylinder, prevents that start cylinder from losing thrust because of gas leakage, the accident that causes 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.In swelling watt, the length that after complete steel coil strip swelling, start cylinder bar continues the to stretch out increment of distance (and between the first inner ring sleeve and circlip for shaft) is to belleville spring by the length of another compression, this length is 2mm.When the parts such as start cylinder, connecting panel, 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 when final unwinding and rewinding machine operation in dish spring group is also just less.For above-mentioned reasons, in unwinding and rewinding machine when operation,, in other words, the axial force after steel coil strip swelling is less, and after machine run gets up, the two-direction thrust bearing in outside and the thrust baring of inner side stressed also less, is conducive to improve the thrust baring life-span.
The generation of second-compressed amount is not only in order to make up the error while installing, and to have the effect that tension force is provided concurrently.Because in the process in fact constantly strutting in swelling watt, swelling watt is only also the gravity that equals material volume for a bearing capacity for material volume, now the elastic force on belleville spring also with this bearing capacity to corresponding.If there is no second-compressed, that swelling watt will be the same (due to the geometric relationship between swelling connecting rod, swelling watt, support link and pull bar with not using dish 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, the positive corresponding generation of 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, ensure that swelling watt and material volume can have enough friction force between inner side (or material roll up paper web), control raising speed/reduction of speed that 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, application force in dish spring group is 800kgf, due to the second-compressed of dish spring group, application force in dish spring group has increased again 320kgf, increased again so the tension force of 400kgf between swelling watt and material volume inner side, this friction force between just having increased inside swelling watt and material volume.
Because the unwinding and rewinding machine or the winder that adopt swelling watt distensible material volume inner core are different from I-beam wheel unwinding and rewinding machine.The material volume of I-beam wheel unwinding and rewinding machine is placed in I-beam wheel (or being referred to as drum), and the rotative speed of I-beam wheel is to embed in the hole in I-beam wheel by the finger on unwinding and rewinding machine, stirs I-beam wheel and rotates to regulate its rotating speed.And the friction force that the rotating speed of the confidential adjusting material volume of the material retractable that adopts swelling watt can only be rolled up between inner core by swelling watt and material regulates its rotating speed, and friction force is determined by tension force and friction coefficient, and friction coefficient be immobilize moving, so can only by increase tension force improve friction force.
Once the piston movement of self-locking cylinder puts in place, the application force that adopts the cylinder of the unwinding and rewinding machine of existing form externally to apply is and overcomes the required corresponding dish spring force of bearing capacity of material volume weight, and the piston area of for example cylinder is 314cm 2, air pressure is 4kgf/cm 2, the power that cylinder can externally apply is in theory 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, friction coefficient between swelling watt and material volume is 0.3, and the friction force of now every swelling watt can only be 300kgf.If swelling puts in place before self-locking, cylinder no longer moves, and cylinder on the contrary can outwards be exported 1256kgf application force, but there is no self-locking, once cylinder leakage tester will be easy to occur the accident that material volume flies out.
But the present invention has increased after belleville spring, belleville spring can also carry out second-compressed, swelling watt can increase again extra tension force, for example increase mentioned above the tension force of 400kgf, and each swelling watt total can increase again the friction force of 120kgf.And technical scheme in employing the present embodiment, raising tension force that can be larger, and then the unwinding and rewinding machine that improves employing swelling watt form is rolled up the control ability of velocity variations to material, the acceleration/accel that can adapt to speed governing time, needs are larger and/or material are rolled up the larger occasion of rotor inertia, have expanded the range of use of such machine.
Three) after swelling has operated; outer baffle is contained in swelling watt; utilize two abutment sleeves and two pilot bars to realize the location to outer baffle; wherein two abutment sleeves have completed point location jointly; longer abutment sleeve has also completed the location that prevents swing; then use nut locking, can play the protective effect of the outer side edges to steel coil strip.
Complete behind the location, outside of steel coil strip, can start the passive band of putting.
Dish spring group in the present embodiment also can be replaced by the elasticity of compression parts of other type, can be referring to other compressibi1ity springs of mentioning in the 11st section of spring chapter 1 spring of Chemical Industry Press's version " mechanical design handbook " the 3rd volume in 2002 of Cheng great Xian chief editor, for example resilient sleeve, cylindroid helical-coil compression spring etc.Nut 16 can replace by the limiting stopper of pin joint or by the locating dowel pin of pull bar axis.
Embodiment 2:
Most of identical with embodiment 1, just change the connection mode of start cylinder and pull bar.In embodiment 1, stretch by start cylinder the contraction that realizes pull bar, in the present embodiment, shrink the contraction that realizes pull bar by start cylinder.
Refer to Fig. 9, taking the pull bar in left side as example, driving the start cylinder 33 of pull bar 17 is also two one group, but different is, and 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 to be also connected with a side arm end of connecting panel 35 by a connector 36.Different: the connecting panel in the connecting panel Length Ratio embodiment 1 in the present embodiment is short, and opening direction is different from embodiment 1.
The present embodiment also provides the connection structure of another kind of start cylinder cylinder bar and pull bar:
Referring to Figure 10, still taking the pull bar in left side as example, 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 connection mode of pull bar 17 the inners.In Figure 11, be provided with the connecting panel vertical with them 46 for the cylinder bar of the start cylinder group that drives pull bar 17, the outer circumference surface of sleeve bearing chamber is provided with the otic placode vertical with bearing chamber axis 711, and otic placode is fastenedly connected by bolt and connecting panel.In figure, draw be sleeve bearing chamber and connecting panel by tying the scheme connecing, also can be directly by sleeve bearing chamber directly and connecting panel integrally welded.
Embodiment 3:
The first structure: refer to Fig. 1 and Figure 11 a, the afterbody of each start cylinder is all hinged on the riser of casing, cylinder bar is connected with sleeve bearing chamber by a lever 35.Sleeve bearing outside is connected with the second otic placode 712 that is parallel to sleeve bearing chamber axis, start cylinder cylinder club head is provided with Y-shaped connector 34, the two ends of lever 35 are hinged with the second otic placode 712 and Y-shaped connector 34 respectively, be wherein elongated slot non-circular hole with the hinged part of the second otic placode, the middle part of lever 35, with to be fixed in bearing 63 on casing riser 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 should be elongated slot and non-circular hole with the second otic placode 712 and the hinged junction, end of Y-shaped connector 34, will cause lever to rotate otherwise connection between three is the structure of " bearing pin+circular hole ".
2 kinds of leverages are different from above two kinds of leverages below, changed the connection 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, realize the contraction of pull bar by the contraction of start cylinder cylinder bar.
The 3rd kind of structure: refer to Figure 12 a, be with the difference of the first structure in embodiment 1: the second otic placode 712 of the middle part of lever 35 and sleeve bearing chamber 71 is hinged, the part hinged with the second otic placode is elongated slot non-circular hole, one end of lever 35 and Y-shaped connector 34 are hinged, the other end of lever 35 is with to be fixed in bearing 63 on casing riser hinged, and bearing 63 and 33 points, start cylinder are located at the both sides of pull bar 17.When start cylinder stretches out, pull bar is side shifting outside casing, and a swelling watt radius is reduced; In the time that 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, be with the difference of above-mentioned the first structure, the afterbody of start cylinder 33 is directly installed on the riser of casing, cylinder bar 35 is for should be elongated slot and non-circular hole with the hinged junction, end of the first Y-shaped connector 34 with the hinged junction, middle part of Y-shaped connector 36, will cause lever to rotate otherwise connection between three is the structure of " bearing pin+circular hole ".

Embodiment 4:
Be the registration device of outer baffle with the difference of embodiment 1.Refer to Figure 13 a and Figure 13 b, in the present embodiment, the registration device of outer baffle comprises and is sleeved on the outer locking of swelling watt watts 53, in locking watts 53, be connected with the holding screw and the radius stay 54 that are pressed in swelling watt, radius stay slides and is installed in spoke 56 through outer baffle inner ring 55, on spoke, be radially provided with slotted hole 561, in slotted hole, be provided with the lock screw affixed with radius stay.Locking watt compresses swelling watt by the holding screw on it and realizes locking, and radius stay compresses spoke by the lock screw on it and realizes location.
Above-mentioned outer baffle registration device, can avoid the large problem of embodiment 1 outer baffle registration device difficulty of processing.Because, in embodiment 1, outer baffle and turnbarrel are except the nested relationship of abutment sleeve and pilot bar, two incoherent parts completely, and overcoat has the outer baffle pilot bar of abutment sleeve to be still 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 pilot bar, increasing tolerance clearance needs to ensure to install, thus, improved the fugitiveness of outer baffle location; Raising working accuracy, increases tooling cost.The two scheme has certain drawback.
Outer baffle registration device in embodiment 1, owing to being provided with outer baffle pilot bar in the end of riser, once pilot bar is stressed, for riser, it is a cantilever beam structure of only having fixed at afterbody, and outer baffle pilot bar 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 radius stay in outer baffle registration device, and radius stay itself is also a cantilever beam structure, if increase the length of radius stay, certainly will reduce again its rigidity and load-carrying capacity.And outer baffle is after material volume is put on unwinding and rewinding machine, be manually installed on unwinding and rewinding machine, 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 is again too much.The two has just formed contradiction.
The present embodiment, the registration device of outer baffle is changed into the locking watt being directly sleeved in swelling watt, locking watt shape and size mate with swelling watt, how the circular outer diameter size no matter swelling watt forms 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 radius stay in spoke when swelling.The present embodiment by holding screw compress swelling watt realize locking watt location, simple in structure, easy to operate.
In the present embodiment, steel band outer baffle adopts plectane to add the structure that spoke adds inner ring, and the effect of spoke is equivalent to gusset.Steel band outer baffle also can adopt the structure of the outer ring+spoke+inner ring in embodiment 1.
Embodiment 5:
Refer to Fig. 8, and the difference of embodiment 1 is: between dish spring support ring 19 and first shaft shoulder of pull bar, clamp and adjust packing ring 60, adjust packing ring 60 and be sleeved on pull bar 17.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 slide axially 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 and pulls the locking start cylinder of pull bar to move completely to put in place, utilizes lock in start cylinder to ensure 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 causing driving the start cylinder cylinder bar of pull bar to put in place, still cannot increase to position, also cannot ensure even again discharge amount of compression by belleville 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 moved inward, need to increase and adjust thickness or the quantity of packing ring, make start cylinder in the time moving to terminal, the external diameter of swelling watt is less than original steel coil strip internal diameter; Vice versa.Adjust packing ring and can have various ways: 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, in the time that the internal diameter of steel coil strip changes to some extent, increase or reduce corresponding adjustment packing ring number; 2) size of required size adjusting packing ring while calculating respectively discharging volume internal diameter and be different size, makes respectively the adjustment packing ring of coil diameter in corresponding each steel band, in the time that the internal diameter of steel coil strip changes to some extent, and integral replacing size adjusting packing ring.
Embodiment 6:
In embodiment 1, swelling watts 7 is connected with swelling connecting rod 10 and the outer gusset 12 of slip cap by swelling watt inner reinforced plate 8, the outer gusset plane of swelling connecting rod one end and slip cap is hinged, the other end and swelling watt inner reinforced plate plane is hinged, and the outer gusset of slip cap and slip cap 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, swelling connecting rod can carry out with respect to slip cap the 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 taking slip cap as system of axes, swelling watt has two degree of freedom.So can claim between swelling watt and slip cap for 2DOF is connected.
In like manner, in embodiment 1, one end plane of one end of two groups of support link 9 and swelling watt inner reinforced plate 8 is hinged, and outer gusset 11 planes of the other end and turnbarrel 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 swelling watt connects and turnbarrel in the mode of parallel-crank mechanism, 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 is only decided by the angle between the outer gusset of support link and turnbarrel, thus between swelling watt and turnbarrel for single degree of freedom is connected.
So for 2DOF is connected, and be that 1 degree of freedom is connected between turnbarrel between swelling watt and slip cap, so connecting, the M degree of freedom described in summary of the invention is connected with N degree of freedom, M+N=3 is this concept.
Except the described swelling of embodiment 1 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, slip cap 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 outer gusset of slip cap 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 slip cap.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 swelling watt, the described swelling watt mode connecting with M degree of freedom is connected with slip cap, is connected with turnbarrel in the mode of N degree of freedom connection, and M is that 1, N is 2, and M+N=3.
In this structure, although the weight of material volume is by swelling connecting rod and support link shared, be that some radial weight is born by slip cap, but as shown in Fig. 1, Fig. 6 a and Fig. 6 b, slip cap is in the time sliding into maximum distance, still some length is embedded in turnbarrel, and diametral load is born by turnbarrel, does not have the problem of utilizing two-direction thrust bearing to bear radial weight.
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 that the one of scheme shown in Figure 14 becomes example, in the breathing plane of movement of every swelling watt, the swelling watt mode connecting with M degree of freedom is connected with slip cap, is connected with turnbarrel in the mode of N degree of freedom connection, and M is that 1, N is 1, and M+N=2.Although M+N=2.But this is connected and causes with slip cap 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 of swelling between them watt and turnbarrel and slip cap length between them 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 cannot have been moved.
The third mechanism:
