The invention discloses a kind of Hooks coupling universal coupling suspender in auto-strengthening joint and its hanging method.A kind of Hooks coupling universal coupling suspender in auto-strengthening joint of the present invention, it is mainly made up of two parts of hoist cable and suspender body, and two groups of left and right suspender is one secondary, and the physical dimension of every group of part is identical；One end of hoist cable is connected with the lifting hole(eyelet) hung particularly by lock pin, and the other end is hooked on suspension hook by suspension ring.Wherein, the lifting hole(eyelet) hung on specific hoist cable coupling part is connected by one end of lock pin and hoist cable, and the setting of lifting hole(eyelet) will at least meet：The distance e ＞ 0 of lifting hole(eyelet) center deviation jaw flange mounting surface, e is the distance of lifting hole(eyelet) center deviation jaw flange mounting surface in formula, and direction is in articulation center the same side.The once dress that is painted on that universal coupling with spider including concertina type need to all can be applied to surface using the suspender and method of the present invention hangs middle completion, so as to improve coating performance, quality and productivity ratio, shortens the duration, has saved cost.
The present invention relates to mechanical engineering field, more particularly to the suspender of universal coupling with spider product painting and its hang Dress method.
The structure of universal coupling with spider is as shown in figure 1, typically by middle adapter 4, interior jaw 3, cross assemble 2 And the major part such as outer jaw 1 composition, middle adapter 4 is mostly the spline pair that can be stretched, and its length is without shaft gear limit, therefore Endways it can not lift by crane, even if endways lifting often has the problems such as coating equipment height space deficiency, operation is inconvenient.Meanwhile join Interior jaw 3, the outer jaw 1 of axle device connect and compose joint, the general each joint in shaft coupling both ends by cross assemble 2；Close Save flange axis within the specific limits, can be around center B one uncertain angle of upper deflecting in any direction of cross assemble 2 (see Fig. 2).This flexibility causes shaft coupling either supports sidewards still to sling sidewards, and the jaw inner chamber 5 in joint can all occur Mutually touching；If Heave Here is the screwed hole of cross assemble head end, there is lifting force small gap whether there is indeterminate problem.Only There is jaw inner chamber 5 and touch or occur the too small situation in gap (as shown in Figure 3), product can be made can not to realize disposable completion Painting work.
Because disposably surface can not need to all be applied application, can cause to influence as follows：(1) coating is as painted the knot with workpiece With joint efforts；(2) outward appearance of coating surface, such as aberration, saturation degree and gloss capability and performance；(3) productivity ratio of application；(4) because more The extra time that secondary application is repeatedly dried consumes and influences the duration；(5) painting cost is increased.
Therefore for the universal coupling with spider including concertina type, currently without one kind lifting or rest method It can be made all to apply the once dress that is painted on surface and hang middle completion.
The above-mentioned surface that need to all apply refers to except installation surface when workpiece couples with working machine, matching surface, screw light Surface beyond hole, installation surface, matching surface, screw unthreaded hole need to only apply antirust oil or antirust grease before packing, it is desirable to It is very low, without application can not be completed in once lifting or rest.
The content of the invention
Problem to be solved by this invention is to provide Hooks coupling universal coupling suspender and its lifting side in a kind of auto-strengthening joint Method, the universal coupling with spider including concertina type surface need to can be all applied using the suspender and method of the present invention Be painted on once dress hang middle completion, so as to improve coating performance, quality and productivity ratio, shorten the duration, saved cost.
A kind of Hooks coupling universal coupling suspender in auto-strengthening joint of the present invention, it is mainly by two part groups of hoist cable and suspender body Into two groups of left and right suspender is one secondary, and the physical dimension of every group of part is identical；One end of hoist cable and the lifting hole(eyelet) hung particularly pass through lock Pin connection, the other end are hooked on suspension hook by suspension ring.Wherein, hang and specifically include hoist cable coupling part and workpiece coupling part, work Part coupling part is connected with the flanged end face of Hooks coupling universal coupling, and the lifting hole(eyelet) on hoist cable coupling part passes through lock pin and hoist cable One end connection, the setting of lifting hole(eyelet) will at least meet (1) formula necessary condition：The distance of lifting hole(eyelet) center deviation jaw flange mounting surface
E ＞ 0 (1)
E is the distance of lifting hole(eyelet) center deviation jaw flange mounting surface in formula, and direction is in articulation center the same side.
The hanging method of Hooks coupling universal coupling suspender of the present invention is：(1) preparation：In advance by the hoist cable of left and right two before work Connected respectively with hanging specific hoist cable coupling part by lock pin, the other end is hooked on suspension hook by suspension ring；(2) work is connected Part：Left and right two is hung into flange of the specific workpiece coupling part respectively with Hooks coupling universal coupling both ends during work to be connected；(3) lift by crane Workpiece：When hook to be steadily lifted to certain altitude upwards, Hooks coupling universal coupling will pass through hoist cable and suspender body is sling by level.
I.e. when lifting by crane universal coupling with spider, using the suspender of the present invention, specific hoist cable coupling part is hung Diverse location is disposed with several lifting hole(eyelet)s；Lifting hole(eyelet) is used to connect hoist cable, is typically just connected using preceding；Specific workpiece is hung to connect Socket part, which is divided to, two holes, and wherein pin-and-hole is used for steady pin, and unthreaded hole is used to wear bolt；Above-mentioned component or so two pieces is one secondary.Root According to working condition, the upper end of the hoist cable on both sides can and in single hook O, it is also capable of hoisting in double hook O2And O3On.During single hook under hoist cable Hold and be connected with hanging the hole A of specific suspender coupling part by lock pin；The lower end of hoist cable is hung specifically with left and right respectively during double hook The hole A of hoist cable coupling part0It is connected, now e=h, h refer to the high l in the center of outer jawBC, double hook is contour, its center O2O3Between Distance and left and right joint BB ＇ centre distance it is basically identical, i.e. lO2O3≈L。
For discussion purposes, universal coupling with spider product and suspender are now simplified into (as shown in Figure 5), rigid The interior jaw 3 of knot represents that the center of cross assemble 2 is in B points and B ＇ points, the method for outer jaw 1 with middle adapter 4 with straight line BB ＇ In C points, pin 14 connects at K at blue center, bolt 13 connected at J with flange 6 and tight, the hoist cable coupling part of suspender body 12 and Workpiece coupling part represents with broken line k1 and k2 respectively, A0、A、A1... represent to hang the center of lifting hole(eyelet) 11 particularly respectively.Will be firm Property connection the outer jaw 1 of workpiece and suspender body 12 be used as a research object, ignore this object own wt during discussion.It is it is assumed that single Hole is lifted by crane, and a is that hoist cable is grown, and a ＇ are the distance of lifting hole(eyelet) center and articulation center, and L is the distance between two joint center B and B ＇, then
Sin θ=BO1/ OB=L/2 (a+a ＇), and sin α=BC/AB=(e-h)/a ＇
If α=θ, workpiece is just able to righting.Now e values are E, and e=E is substituted into above formula, drawn：(E-h)/a ＇=L/2 (a+a ＇), i.e.,
E=h+a ＇ L/2 (a+a ＇) (2)
Thus (2) formula is found out, as distance a ＇ of the long a of hoist cable, lifting hole(eyelet) away from articulation center, the distance L and work at two joint center The high timings of h mono- in part center, (2) formula condition can be met by the distance E of lifting hole(eyelet) to outer jaw flange mounting surface so that joint jaw By righting.
The principle of auto-strengthening joint of the present invention hanging method：So that single hook lifting hole(eyelet) is A holes as an example, workpiece weight is G in work Part center O1, such the studies above object is by two power, i.e. the active force P of the pulling force T of hoist cable and workpiece, two hoist cable angles Half is the power of θ, T and P two as schemed to decompose two component T in the horizontal direction respectively2、P2And vertical direction component T1、P1, difference size Equal direction is on the contrary, i.e.
T=P, T1=P1, T2=P2
T1The reverse extending line in direction hands over BO1In point C, then BC=AC*tan θ,
And P1=G/2, P=P1/cosθ
Therefore T1=T*cos θ, T2=T*sin θ
Further studied using B as center of rotation again, research object is in addition to stress, also by two torques：
M1=T1* BC=T*cos θ * AC*tan θ=T*AC*sin θ
M2=-T2* AC=-T*sin θ * AC
E is known in calculating1+E2=0, it can be seen that, when being sling using this suspender, not only dynamic balance, torque also balance, so rising Outer jaw will not upwarp or sagging when hanging, and in line, i.e., joint is positive to outer jaw axis BC and axis of workpiece BB ＇； And so righting is automatic, as long as it is all positive all the time to sling.
If double hook O2、O3By hoist cable in hanging A particularly0Hole steadily lifts upwards, now e=h, takes lO2O3≈L′, Then T in Fig. 52=P2=0, M1+M2=0, T=T1=P1=G/2.Therefore, workpiece joint can also be sling by righting.
Only joint appropriate gap could occur by righting, joint cavity 5, so as to spray to jaw inner chamber.So, two Jaw inner chamber is not touched, and associated outer surface does not also contact directly because of lifting or rest and with the external world, and this is advantageous to disposably complete The application on surface need to all be applied.
The above-mentioned surface that need to all apply refers to except installation surface when workpiece couples with working machine, matching surface, screw light Surface beyond hole, installation surface, matching surface, screw unthreaded hole need to only apply antirust oil or antirust grease before packing, it is desirable to It is very low, without application can not be completed in once lifting or rest.Also it is exactly the installation for having these to complete application simultaneously Surface, the presence of matching surface, screw unthreaded hole, and the supporting for making good use of these surfaces could cause in addition all with contacting The once dress that is painted on that surface need to be applied hangs middle completion.
Suspender advantage of the present invention is：(1) simple in construction, cost is cheap, only need to particularly bore several holes hanging；(2) it is automatic Righting, easy to operate, meeting nature normotopia in joint when slinging, consistently；(3) convenient mounting and clamping, often end pin is to living behind hole and tight one Individual bolt；(4) fulcrum is propped up when can set on suspender and prop up platform, while solve to dry the non-dry coating of workpiece occurs The problem of touching, carry out all applying application and the drying on surface here when can also hold up.
The present invention hanging method advantage be：1st, workpiece accumbency, solve either long or short all including concertina type Universal coupling with spider product painting is lifted by unified mode, is easy to production line operation；2nd, joint is when slinging It is self-righting, if being used for application, the once dress that is painted on that need to all apply surface can be made to hang middle completion, so as to improve application Quality and productivity ratio, shorten the duration, have saved cost；3rd, single hook or double hook are applicable, and conveniently adapt to different production types.

It was found from Fig. 4, Fig. 6, a kind of Hooks coupling universal coupling suspender in auto-strengthening joint of the present invention, it is mainly by the He of hoist cable 10 12 two parts of suspender body form, and two groups of left and right suspender is one secondary, and the physical dimension of every group of part is identical；One end of hoist cable 10 with Lifting hole(eyelet) on suspender body 12 is connected by lock pin, and the other end is hooked on suspension hook by suspension ring.Hoist cable is generally steel wire rope or iron chains Formed Deng flexible element, the hoist cable of left and right two is isometric.
Wherein, suspender body 12 includes hoist cable coupling part and workpiece coupling part, workpiece coupling part and Hooks coupling universal coupling Flange 6 install end face be connected, the lifting hole(eyelet) 11 on hoist cable coupling part is connected by lock pin with one end of hoist cable 10, lifting hole(eyelet) 11 Setting at least to meet (1) formula necessary condition：E ＞ 0, e is the distance of lifting hole(eyelet) center deviation jaw flange mounting surface in formula, side To in articulation center the same side.
(1) formula is the necessary condition in righting joint, meets that (1) is not enough to righting joint, wants righting, also needs satisfaction following (2) formula adequate condition：
E=h+a ＇ L/2 (a+a ＇) (2)
From (2), formula is found out, must meet (1) formula because each is both greater than 0 on the right of equation.
As e=E=h+a ＇ L/2 (a+a ＇), single hole can make its auto-strengthening；It is single when e is near E in certain limit Hole can make its automatic relative righting.
Lifting hole(eyelet) 11 has several, or E can be moved by changing the long a of hoist cable, and joint tilting position can be made by selecting hole or becoming rope length In ± the β of permission0Within.
Pin-and-hole, unthreaded hole or buckle etc. are provided with the workpiece coupling part of suspender body 12, for the method with Hooks coupling universal coupling Orchid 6 connects.Certainly, the connected mode of suspender body and workpiece is not limited only to these above-mentioned forms.
As shown in fig. 6, to control outer jaw to upwarp and sagging amplitude, as a modification of the present invention mode, suspender body 12, which also include support section, props up platform 15, and it is arranged on the bottom of hoist cable coupling part, and it is with front and back support 17, cross bar 16 Concur, horizontal positioned cross bar 16, can hold up workpiece on former and later two supports 17.Workpiece can be carried out full when lifting up Portion need to apply the application on surface and subsequent drying, and be not limited to application and drying.The outer jaw of control upwarp and sagging amplitude not It is to be completed by coating surface contact (such as support, pad), but turns what the non-contact form of structure was realized by suspender band.This Sample, the problem that fulcrum is touched to the non-dry coating of workpiece is propped up when can solve to dry, carried out when can also hold up here complete Portion need to apply the application on surface and drying.
The hanging method of Hooks coupling universal coupling suspender of the present invention is：(1) preparation：In advance by the hoist cable of left and right two before work Connected respectively with hanging specific hoist cable coupling part by lock pin, the other end is hooked on suspension hook by suspension ring；(2) work is connected Part：Left and right two is hung into flange of the specific workpiece coupling part respectively with Hooks coupling universal coupling both ends during work to be connected；(3) lift by crane Workpiece：When hook to be steadily lifted to certain altitude upwards, Hooks coupling universal coupling will pass through hoist cable and suspender body is sling by level.Step Suddenly during (2) connection workpiece, the end face of the inner surface of suspender coupling part and the flange 6 of Hooks coupling universal coupling is brought into close contact, it is fixed Pin 14 is passed through and passed through on flange 6 with screw 7 on bearing hole vertical phase or the unthreaded hole 8 of neighbouring phase, bolt 13 on flange 6 with wearing It is in the screw of the 180 ° of positions in hole of pin 14 and tight；Lifting hole(eyelet) has multiple, is distributed in suspender body diverse location, sling length also have with It is short, to adapt to the occasions such as single hook or double hook, it is also adapted to the workpiece of different length or the different outer high l in jaw centerBC。
Four in the distance L and the high h of workpiece centre of distance a ＇, two joint center when the long a of hoist cable, lifting hole(eyelet) and articulation center Any when changing in factor, the distance e of lifting hole(eyelet) to outer jaw flange mounting surface cannot meet (2) formula condition, joint fork Head cannot be by righting.But if using as shown in fig. 6, suspender body is set in its lifting part diverse location being connected with hoist cable There are multiple lifting hole(eyelet)s 11, its center is A, A0、A1..Ai..., the e values in its each hole are ei, in these eiAlways have in value close to (2) The E values of formula, so as to ensure that e values are between E in joint knuckle i.e. Fig. 71Between E.
Fig. 7 is change curve of the joint angle of inclination beta of the present invention with e values, and ordinate is angle of inclination beta, and joint upturned direction is just, instead The sagging direction in joint be negative, jaw flanged end face is starting point beyond horizontal coordinate, to articulation center direction for just.If O2O3The distance between l consistent with the centre distance in left and right jointO2O3=L, isometric double hook are hung in lifting hole(eyelet) A0, then joint can help Just.Line segment n, p, q are the function curves of joint angle of inclination beta change, hand over trunnion axis in E points, βmaxFor the inclination maximum in joint.If Using single hook, when (2) the formula condition of satisfaction：During E=h+a ＇ L/2 (a+a ＇), joint also can righting.Spraying allowed maximum angular Degree ± β0Within scope, two e limiting value be present：E1And E2, the e of every suspenderiBe worth it is intervenient sprayable, be referred to as Region (being illustrated as grid scope) can be sprayed.Wherein work as eiValue is between E1Between E, joint upwarps in limited range, works as eiValue between E and E2Between, joint is sagging in limited range.A ＇ value typically wants coincidence formula a ＇ >=d/2+60, is otherwise allowed not open with workpiece, Without engineering significance, but it is too big, because space is big also unsuitable with suspender weight.From (2), formula is known, if L and a ＇ are constant, changes a E can be moved, E1With E2Also change therewith, so that limited lifting hole(eyelet) eiJoint inclination angle is set to be in ± β0Within.
When specifically being lifted, it may occur that some change, L is relevant with product, different in size, and a is relevant with frock, a ＇ and Suspender and product are all relevant：
Sin θ=L/2 (a+a ＇)
β=θ-α=sin-1[L/2 (a+a ＇)]-α
Therefore size during use, angle and lifting force all can because specification it is different change, in multi items or This problem is more prominent during jobbing work.
In order to solve " relative the to help not just " problem sometimes of joint caused by above-mentioned change, according to product variations situation, use Several different length a hoist cable, and lifting hole(eyelet) is set on specific diverse location is hung, according to different product, comprehensive selection makes With the hoist cable and lifting hole(eyelet) of these different lengths, make lifting force size appropriate and the limited righting of jaw is to meet production line and product bar Part.The long a of hoist cable will adapt to product length and produce the mechanical property requirements of space of lines and hoist cable, when lifting hole(eyelet) is set, cross B and make BC's Vertical line hands over suspender bar center in A0, D is in A0Lifting hole(eyelet) is beaten at place, then in A and A0Between or extended line on beat some lifting hole(eyelet) A1、 A2... Ai..., such BA0With BA, BA1...BAiAngle be respectively α, α1...αi...。
As θ=α, β=0, joint, can be with application as previously described by righting；
As θ ＞ α, β=θ-α=sin-1[L/2 (a+a ＇)]-α ＞ 0, the axis BC of extrinsic articulation 1 can still upwarp a β The state at angle, i.e. Fig. 6, now if eiValue is between E1Between E, joint pitch angle control is in maximum angle β0Within scope, also may be used With application；
As θ ＜ α, β=θ-α=sin-1[L/2 (a+a ＇)]-α ＜ 0, the axis BC of extrinsic articulation 1 will be to opposite direction Rotate and a sagging β angle, now if eiValue is between E and E2Between, joint pitch angle control is in maximum angle β0Within scope, Can also application.
If workpiece length is certain to size L, as long as different hoist cable long a and correct position a ＇ of reasonable selection lifting hole(eyelet), makes Obtain β value and be less than the value ± β that application is allowed0, still can be whole by the universal coupling with spider including concertina type The once dress that is painted on that surface need to be applied hangs middle completion.Because workpiece size, inclination angle, torque are different, the workpiece fork girth of a garment is different, The space size of the jaw inner chamber 5 formed between outer jaw and interior jaw is different, therefore the β that application is allowed0Value also has Institute is different.In order to ensure quality, not only universal coupling with spider need to all apply surface be painted on once dress hang middle completion, Large quantities of a large amount of productions can use rapid draing technique, and suspender solidify afterwards are unloaded after quick-drying, but for the stream of jobbing work Waterline operation, drying after application using quick-drying technique or no drying equipment, drying process length, are owned in the process Coating surface can not be touched, such case using unloading hoist cable, allow suspender body 12, bolt 13 and pin 14 and workpiece still together with connect Workpiece is dried in the state of connecing.
Hoist cable is unloaded, suspender dries what is be realized in together with workpiece：One support 17 is set, and level is put on support 17 Cross bar 16 is put, setting one on suspender body 12 props up platform 15, props up platform 15 and is placed on cross bar 16, such workpiece is just held in the palm Rise.The position dimension L that support 17 and cross bar 16 are placed2Want appropriate, in theory L2Should be consistent with working size L, L in practice2Choosing Selecting allows have a little error, not to be touched and easy to operate is defined by the surface of jaw inner chamber 5.It can also prop up in this way Application is carried out after support and suspender retinue is together dried.
The suspender of the present invention has righting function to joint, is made using surfaces such as installation surface, matching surface, screw unthreaded holes Supporting, it overcomes the weakness that joint is mutually touched by flexible prong inner chamber, and outer jaw will not upwarp and sagging when slinging, Or control it to upwarp and sagging amplitude, make β ＜ β0, outer jaw axis forms straight line with axis of workpiece or drift angle is smaller, so Righting function is automatically, all the time.Therefore this suspender is when being used for application, except installation surface, matching surface, screw unthreaded hole this A bit without application beyond, it is all need to apply surface be painted on once dress hang middle completion.Control outer jaw upwarps and sagging amplitude Suspender is not limited to application, it does not touched suitable for all jaw inner chambers and the associated outer surface of workpiece also not because lifting or rest and Use occasion is directly contacted with the external world.
