Description
Technical field
The present invention relates in paper machine/board machine in or change the apparatus and method of endless belt or corresponding component in the polishing machine, comprising at least one annulus wheel zone circle.Can be applied to change the conveyer belt and the felt of various paper/board machine and textiles machinery according to technical scheme of the present invention.The replacing conveyer belt is considered to difficulty always, and these problems can become serious further because of the increase of paper machine amplitude.The wide cut of the size dimension of conveyer belt, especially conveyer belt correspondingly increases, and at this moment handle, and it is also more difficult under situation so closely conveyer belt to be passed machine.
The present invention can be applicable to the metal belt of changing annular especially effectively.The endless belt conveyer of changing long distance is relatively more difficult, particularly the calender of metal belt.This calender has been installed conveyer belt around at least one belt steering apparatus, the counter element that at least one and conveyer belt form contact-making surface has been installed in the outside of conveyer belt, form the calendering zone like this between conveyer belt and the corresponding element, the paper web guiding is carried out work by this calendering zone.For example, the Condebelt type comprises in the treatment facility of fibroid paper web of metal belt loop, all is for example conveyer belt to be cut off in the past, passes machine, and then two of conveyer belt is welded together again.So again welding in quality, is not passed through the conveyer belt high-quality of special process (for example, LASER BEAM WELDING) welding certainly in factory.
Background technology
In order to change conveyer belt and felt, formerly method and converting means have been introduced equally among publication FI 102845B and the FI 991171A the applicant, so that particularly in roll squeezer, change annular carpet band, installed new felt band in the roll squeezer so that be promoted to around the lifting beam that independently prolongs.Lifting beam is connected on first roll shaft, and the felt band passes around first roll shaft and the inboard roll shaft of other felt bands, and first roll shaft descends then, is fixed on the original position, and lifting beam is decontroled from first roll shaft.But such structural requirement, at first the frame structure of machinery must be to construct as much as possible on the transmission device that promotes first roll shaft.Particularly as this device that improves equipment, this structure might not be used.In addition, very heavy based on the heavy lifting beam of crane motion, it is slow to operate, and also is problematic from the work safety angle.
Introduced solution and machinery among the patent application EP1375744A3 on the one hand, wherein used independently adjusting to settle support in order to take turns band.Regulate the chain of command of settling support to be installed in paper machine, and be inducted into the operation support from taking turns band there, be inducted in the paper machine from there by sticking device or corresponding device thereof.Adhesion equipment needs device crossbeam and the guider that is connected therewith, like this on the structure that is fixed on paper machine that can two parts are more firm.This structure and the part that all are necessary are formed a very complicated structure together, and needs and internal structure thereof have sufficient space.Particularly as this device that improves equipment, this solution is difficult to use.
In addition, introduced structure among applicant's the FI114404B1 of patent formerly, on the medial cradle structure of wheel zone circle, crossbeam has been installed in order to change the wheel band in the sort of calender at metal wheel band calender.Here, all take turns the roll shaft of the inboard of zone circle all must be detachable, takes out from machinery.This time-consuming in order to change the method that wheel band takes, and in this case, the effective time of machine will significantly reduce.In addition, the dismounting of roll shaft needs very large space, has increased the width of papermaking lathe factory building, and in addition, also has hidden danger from the security consideration of working.
Summary of the invention
As previously mentioned, main purpose of the present invention provides actual solution, in this way, can take turns band than replacing quickly in the past, does not need the parts of the teardown of engine, and better security performance before can providing.In addition, the objective of the invention is to make the mechanism of mechanical realization compacter, simpler, the structure of machine can be lighter, simpler like this, reduces simultaneously that the machine wheel band uses and the expense that produces.Also having a purpose is exactly that this method can also provide solution at modifying device equipment and existing machine.
In order to realize these targets, the characteristics that have according to solution provided by the invention are described at the characteristic of claim 1.The solution that is provided according to invention also describes in detail at the characteristic of claim 14.Follow-up developments part of the present invention also has statement in relevant application.
The most essential design of the present invention is, by this device is that more convenient and quicker upwards promotes the inboard mechanism of required wheel zone circle, and promote the related mechanical structure of action and in the mechanical structure of oneself, can operate at any time, simultaneously can be by conduction mechanism with accumulation of energy.The wheel band that is installed in the machine or disassembles from machine can be installed by these lifting structures when needed.The required mechanism of lifting work oneself paper machine or board machine in ready, can enter work desired position and state very rapidly then.Can finish more changing jobs of wheel band rapider, more easily.Same method can disassemble the wheel band from machinery, new wheel band correspondingly is installed in machine, and is not needed the teardown of engine.The structure of lifting wheel zone circle inboard and dismounting wheel band, and promote and install new wheel band accordingly, can pass through same mechanism, in same working time section, carry out.The advantage of being worth mentioning is that this structure can be installed in the existing machine.Can reduce expense like this, under various situation, improve and the process of quickening to change different free of discontinuities wheel bands, in the time that shortens interruption of work as far as possible, when improving operation rate of machinery, achieve effective control.Based on the extraordinary problem that has solved the replacing of metal wheel band of solution provided by the invention.The disposed of in its entirety wheel is with (the just whole zone circle of taking turns) if desired, for example not need the dismounting before the cut off wheel band, or need the integral installation wheel to be with, needn't when next new wheel band is installed, weld transverse joint, just must take out from machine from this phozy of wheel tape base ground that machine disassembles.This hour wheel band requires to have enough spaces and the enough balanced level and smooth support platforms of width, will take turns the band after machine disassembles, can put on this support platform, and correspondingly, before new wheel band is installed to machine, the wheel band can be placed on the support platform on this machine next door.In this mechanical structure of the present invention, realize a dislocation in its all working method, very big space is arranged promoting between the mechanical structure of operation, wheel is with and can be placed into corresponding position without a doubt and gets on like this.Particularly under the wheel band situation of metal wheel band and overall fixed, it is highly important that on the horizontal direction of installing, a support platform that overall flat is straight is arranged, as supporting mechanism.In the practical operation, preceding making demands is will reduce to take turns in this supporting mechanism with corresponding part on the horizontal amplitude, because the wheel band will be installed in the there.
Here it must be emphasized that in addition, as the replacing method of all mentioning special metal wheel band before and afterwards, can solve the replacing problem of the textiles equipment of different wheel bands, felt band and other annular paper machines, board machine and polishing machine equally well based on mechanical structure of the present invention.

The specific embodiment
Fig. 1 shows a kind of formed mechanical structure of wheel zone circle of sealing.In this case, wheel band calender comprised the mangle wheel band 2 of running around main control roll shaft 3 ', need regulating wheel band 2 ' pressure or/and during the length of processing region, one of them part of this group main control roll shaft 3 can move.The ring of mangle wheel band 2 ' the follow roll shaft 5 of installation, advance in the outside of roll shaft 5, then wheel be with 2 ' and roll shaft 5 between form adjustable calendering zone in the vertical.Being shown in dotted line as the roll gap roll shaft 4 of briquetting machine among the figure might be with 2 at wheel ' compress roll shaft 5, to form powerful pressure in the calendering district of roll-gap region.Roll shaft 4 as briquetting machine can be the contraction pressure structure of other shapes or fixed profile, and this in addition compacting pressing mechanism can be made up of the continuous part transversely of more more machines.Briquetting machine in the same operation can be made up of the continuous part of more more transverse machine, uses as roll shaft 4.Equally, briquetting machine 4 can be installed, so that the pressure that tightens up of band is taken turns in the length in conversion process zone and/or change.
Here, the mechanism of wheel zone circle inboard refers to all mechanism's parts that are fixed on the machine, comprising: for example take turns roll shaft 3 and its bearing housing of zone circle inboard, they pass through all interrelated co-operation of conduction device roll shaft group when being supported; And between the framework of roll shaft and machine mechanism's part of transmission power, and self work as roll shaft 3 and roll shaft 4.Equally, the long beam of possible load-bearing and other horizontal beam frame structures all belong to the mechanism that these take turns the zone circle inboard.These mechanisms generally are expressed as Reference numeral 8.Substantially the just background information that the calender mechanism that has described in detail before being familiar with and the structure of frame mechanism and function thereof here also will be described in detail again is so that understand better.
Operator scheme is as shown in Figure 1 represented with Reference numeral 20 based on constructed supporting mechanism of the present invention.Under the situation of Fig. 1, supporting mechanism has been installed two elements, but these elements can be one, also can be more a plurality of.Supporting mechanism 20 can be made up of effective particulate metal beam frame structure, and this mechanism can for example finish by welding.But problem may be, for example HEB roof beam structure or any roof beam structure shape.As among Fig. 5 to Fig. 9 effectively beam frame structure can stretch, Comparatively speaking, the abundant length of the position that stretches out like this is several times of length on the inside punctured position.
In this case, advantageously, the length of supporting mechanism on the described mechanism part 8 of machine 1 and the path between the dislocation 24 during telescopic variation, than removable take turns with 2 ' wide cut big.At this moment, wheel enters corresponding part with being with 2 ' transversely phozies, and after machine disassembles or before being installed on the machine, can be placed on the supporting mechanism more easily.In addition, supporting mechanism 20 is by conduction device, and mechanism's lifting of guide wheel zone circle 2 inboards simultaneously is so that provide enough spaces for new wheel band is installed.
In essence, stipulated that supporting mechanism 20 can bear the strength of guiding dislocation 24 on the outward extending position and mechanism's lifting of wheel zone circle inboard is to need directed force upwards, and the torsional strain that causes thus, do not change and do not produce too much diffraction simultaneously.Equally, also will consider the problem of receiving mechanism 22 on the position that stretches out when these solve, receiving mechanism 22 will keep supporting oneself, relies on the weight of conversion equipment 11 thereon and the weight of auxiliary body 12 when needing.These mechanisms all are the slave parts that designs for the operation of receiving mechanism 22, and these parts are all inclined and leaned against on the receiving mechanism 22.
Supporting mechanism 20 is installed in the described mechanism 8 by bearing effectively, so only needs man power just can outwards stretch or inwardly is contracted to different desired positions.Comprise two parts according to the supporting mechanism 20 shown in the operator scheme among Fig. 1, but can be an element, also can form by more a plurality of elements.
The receiving mechanism of installing can be the beam frame structure of interior sky, or transversely the supplementary structure 22 that extends to the machine frame construction part in the corresponding machine 1, it can conduct power the auxiliary frame 41 and 42 to chain of command HP and operating surface KP effectively, and its inboard can be supported this supporting mechanism 20 effectively and supporting mechanism 20 can be free to slide.What also need to consider is, receiving mechanism might be installed under the particularly this situation about improving equipment or conduct on the frame structure of reception by the power or the corresponding strength of its approach with the long beam of existing load-bearing.Here an important advantage of the present invention as can be seen is exactly not need other different and unnecessary heavy supports to assist mechanical structure or corresponding mechanism arrangement.
Want the mechanism 8 of lifting wheel zone circle inboard, the described auxiliary frame 41 of machine 1 and 42 and the framework 9 of wheel zone circle bottom between need to be provided with a support level (not mentioned before), the mechanism 8 that surrounds around the support level can come lifting by supporting mechanism 20.Support level can be by for example forming with reference to machine 1 syndeton in the vertical.
In Fig. 3 and Fig. 4, introduced based on other settling modes of the present invention, at wheel with 2 ' and the different conversion equipment 11 set up.Here, the casing of this conversion equipment 11 is made up of two parts, promptly as wheel with 2 ' the support frame 12 and substructure 14 of supporting mechanism by the support frame that is connected with structure 16 that support frame 12 fixes.The setting of the substructure 14 of this conversion equipment is in order to move the device that solves auxiliary power on the floor of mechanical factory building, such as the factory building suspension bracket.Substructure 14 can be leaned on for example gear support (not mentioned before) in addition, and can make whole conversion equipment 11 be more convenient for moving.
Simultaneously, should be noted that, although the structure by supporting mechanism lifting wheel zone circle inboard was mentioned in the front, what need consideration equally is, particularly the moving movement of the lifting that upwards guides from original position moves to other suitable directions, and this is that the replaceable mobile possibility that provides of taking turns band just is provided.For example might design such moving, by supporting mechanism can support wheel zone circle inside, shorter time ground structure, the structure of simultaneous wheels zone circle outside can move, so that to the replaceable mobile possibility that provides of taking turns band.For example the already mentioned outside and particularly the mechanical structure of bottom can move down, the structure of simultaneous wheels zone circle inboard can rely on supporting mechanism, enough spaces is provided for the wheel Tape movement.
In the conversion equipment 11 that designs based on the present invention, wheel band can directly move to especially easily the lifting crossbeam around, perhaps move to therefrom roll shaft around, only need the man power push-and-pull to get final product.Moving of wheel band can be assisted by favourable coating in surface 13, perhaps for example realizes the structural detail of bearing effect.Not need must be a complete integral body on surface 13, as long as can structure play the effect that alleviates machinery weight that comprises, and cavity 18 for example.In a solution of the present invention, moving structure being installed, is exactly the push-and-pull member, and by this push-and-pull member, moving of wheel band can be finished.Can also use, for example point to wheel with 2 ' edge adhesion member and line or capstan arrangement.
From conversion equipment 11 aspects at the wheel band, it should be noted that at last, the solution that designs based on the present invention not necessarily needs to use this different conversion equipment 11, only need to determine to take turns to be with to guide to by suitable mode to change the position, pass supporting mechanism 20 again before the lifting and enter machine from there.The corresponding wheel band that disassembles from machinery can be transferred to supporting mechanism before removing.
Will introduce among Fig. 5 to Fig. 9 the corresponding mode that designs according to the present invention below to change wheel and be with 2 '.The example of the solution of being mentioned in the problem is applicable to the wheel band of changing metal wheel band calender here.The problem that solves is the example of very simple pattern, this example does not limit the scope of application of this invention, the just solution that designs based on the present invention in this case with the example explanation and the method for means running, by these methods, it is feasible changing the whole operation of taking turns band.
In the initial situation among Fig. 5, machine 1 is out-of-work.Supporting mechanism 20 is during this period of time in internal structure receiving mechanism 22 inside.The chain of command HP of the machine lifting that can make progress in the meantime for example is raised to the dislocation 24 of supporting mechanism 20 by the factory building suspension bracket.Rotating support bar 28 goes to vertical position and pinning, and shift out from the part of chain of command HP together with whole inboard mechanism 8 of taking turns zone circle 2 this moment, rests on the supporting part of support bar 28.Simultaneously, the distance piece that may exist that is connected with framework 9 with the auxiliary frame 41 of chain of command can be taken out.To mention the substructure 14 of the conversion equipment 11 that exists at the wheel tape running below.This can be advanced, and for example passes through the floor of the approach of factory building suspension bracket along the lathe factory building.This substructure can be designed to the device that wheel is installed or helps accordingly moving.Substructure 14 is locked on its position, and the height that is fixed on the top of this support frame 12 above substructure can be adjusted to suitable position to be complementary with the wheel zone circle.The load-carrying members on the top of support frame 12 can be installed an end of machine 1 dorsad, the framework 41 of the chain of command of facing machine 1 especially by the outward extending supplemental support mechanism 26 of design.
In order to help operation, conversion equipment and the particularly top of its support frame 12 of assisting are positioned at least mechanism 8 about 1.0 meters apart from machine 1.From conversion equipment 11 aspects, it should be noted that the casing of conversion equipment 11 can integral body guide to desired location certainly, and same, machine is also in work.
Supporting mechanism 20 now can be by the rope 30 that is connected with dislocation 24, and drawing passes the top of support frame 12.After this supporting mechanism 20 can be locked in extended position, unloads rope.Simultaneously can install rope, so that after a while supporting mechanism 20 is drawn at the other end of supporting mechanism and the operating surface KP of machine.Framework 41 can reduce equally now and is placed on the supporting mechanism 20, for take turns with 2 ' move, need be adjusted to the relevant position.
By the conduction of factory building suspension bracket and supporting mechanism 20, the framework 41 of chain of command now can lifting some, the auxiliary support bar 28 of Zhuan Donging can trailing wheel band 2 like this ' the path on leave, as shown in Figure 6.The framework 41 of chain of command HP can be supported on the supporting mechanism 20 of outside stretching now.Wheel is with 2 ' now can be pulled outwardly from machine and extend on the support frame 12.The outside stretching of wheel band can for example be finished by capstan winch.Support frame 12 is assigned on the position of wheel zone circle 2 like this, and it is symmetrical with the shape of monolithic wheel zone circle effectively to be shaped.This hour wheel band moves from machine 1 and breaks away from, directly move to support frame 12 around, this moving can be realized fast swimmingly.Rotating support bar 28 turns to vertical position again, and the framework 41 of chain of command HP can descend as shown in Figure 7 again.Supporting mechanism 20 release from the outside position, and the rope 30 of supporting mechanism 20 by oriented manipulation face KP is tracted inwards to interior location.Can take support frame 12 now away and unload the wheel that is placed on the support frame 12 from machine 1 be with 2 '.
In Fig. 7, illustrate equally at adhesion for make wheel with 2 ' move more convenient and supplementary structure design, particularly Acetabula device 49.Can under the situation of metal wheel band, realize effective control, and not damage the wheel belt surface by described Acetabula device from the power transfer of taking turns belt surface.Described sucker can be be respectively only installed and used separately by the conduction of man power or the auxiliary power unit by for example hoisting apparatus.When particularly using auxiliary power unit, sucker can be designed as an overall fixed and installs, and it is interrelated by the conduction of assembly fixture perhaps to be installed as a group.At this moment, the wheel band can controlledly slide, and distributes uniformly for moving the power that produces, and does not need other unnecessary compromise method or corresponding nonessential solutions at the wheel band simultaneously.
Consider on machine install wheel with 2 ' be opposite order.As situation represented among Fig. 8, new wheel band guides to changes the position.By the desired location that supporting mechanism 20 stretches out, the mechanism 8 of wheel zone circle inboard upwards is lifted to the origin-location.The dislocation of supporting mechanism 20 extend out to an end that deviates from machine of framework 12 along transversely passing support frame 12 once more.Support bar 28 is rotated away from the path of wheel band again, and at this moment the wheel band can move to machine direction.Very explicit is, as the described wheel band integral replacing of finishing according to the present invention before, described mechanism and method are equally applicable to take turns the dismounting of band or the installation of corresponding wheel band, or as taking turns band or the wheel band correspondingly is installed with the additive method dismounting based on installation and removal mode of taking turns band of the present invention.
Install after the wheel band, the distance piece that may exist (before not introducing) can be mounted to desired location, and support bar 28 turns to lower position, relies on the mechanism 8 of supporting mechanism 20 load-bearing to descend, and pins the mechanical function of machine 1, so that make it ready.Equally, supporting mechanism 20 can stretch, for example by 30 stand-by states that are stretched to originally in receiving system 22 inside of restricting.Remove empty conversion equipment 11 at last.
Noticeable advantage is relative known technology in the structure that designs based on the present invention and the solution.At dismountable band of taking turns, by spurring empty conversion equipment 11, the replacing of wheel band can be finished in machine 1 still operates.Same when new wheel band is installed, also can operate like this, the new wheel band that has been about to regulate guides to support frame 12 places that change the position, and is then ready.Because do not need the componentry of the teardown of engine 1, can very firm very easy operation together with the mechanical structure of machine 1 lifting apparatus, and because wheel band can be easily directly transferred to from the machine more on the changing device 11 and corresponding machine, whole replacing operation can be finished very rapidly, do not need very big space, do not need a lot manually yet, consider that from staff's angle security is also very high.
Special advantage is, based on the structure of bracing or strutting arrangement of the present invention standing part as machine 1, says from structure, can make the structure building light, helps supporting.Mentioned dual auxiliary beam frame structure does not need machine to possess more bearing capacity special on other frame structures.Gravity by two auxiliary frames 41 that are assigned to machine of equilibrium and 42 with and between structure on.Because the reason of technique for fixing does not need necessary unnecessary supporting mechanism, structure is also simpler than other on making, and does not need too much space, so this structure also can be used as the use that improves equipment, is applicable to already present machine.The downtime that can shorten machine to change like this and produce, the hoisting machine utilization rate, thereby especially effectively reduce expense.
In the example of operator scheme, the lifting action of the mechanism 8 of wheel zone circle inboard had been introduced and can have been realized from the chain of command HP of machine.What need equally to consider is, this side that the supporting of described mechanism 8 can be by supporting mechanism 20 or opposite side or any side are finished, and more important what mention is that the chain of command HP of facing machine 1 or that side of operating surface KP are finished.
Equally, in the example of operator scheme, the lifting of supporting mechanism 20 is by the drawing-in motion of factory building suspension bracket from the top, and man power moves apart dislocation 20.Can consider that equally the lifting of supporting mechanism is finished by the pushing action from the below, for example the device by hydraulic power.
Equally, be contemplated that in the operator scheme that designs according to the present invention that the mechanism 8 of wheel zone circle inboard finishes by bracing or strutting arrangement 20 from chain of command HP lifting, the operating surface KP of outwards traction guiding of bracing or strutting arrangement 20 machine.This is to pass through tractive force, and for example help of capstan winch structure is with the power guid supporting mechanism that is directed downwards.In addition, change the wheel band and can remove from the chain of command HP of machine 1, for example the help by conversion equipment 11 as the man power of describing before that passes through.At this moment, also might disassemble and the stage of new wheel band between installing at old wheel band, the part of wheel zone circle inboard is remained on the lifting position, because traction supporting mechanism 20 is outwards to the conducting track of the power of operating surface KP, the pulling device of cable and other adaptations not wheel with 2 ' the path on.This is also need not bring to desired location in order to move apart the wheel band that has unloaded or new wheel to be installed, and reduces mechanism 8, finishes when these operations can be in the lifting state in mechanism 8 always.
