Den foreliggende opfindelse angår en dobbeltregulering for arbejdsredskaber, i særdeleshed kraner, der er placeret på et køretøj, hvilken dobbeltregulering omfatter to reguleringsaggregater, der kan placeres på to modsatte langsider af nævnte køretøj, og som hver har 5 flere manuelt betjenelige reguleringselementer, der er anbragt på en i alt væsentligt vandret række, og som er indrettet til i påkommende tilfælde at aktivere et tilsvarende antal manøvreorganer, f.eks. hydraulikventilstempelstænger, der bestemmer arbejdsredskabets funktioner, hvorhos reguleringselementerne i de to aggregater er 10 parvis forbundne med hinanden på en sådan måde, at et givet manøvreorgan vil blive aktiveret, uanset om det er det ene eller andet element fra et med dette organ samvirkende elementpar, som bliver manuelt betjent.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double control for work tools, in particular taps mounted on a vehicle, which comprises two control assemblies which can be placed on two opposite long sides of said vehicle, each having 5 multiple manually operable control elements disposed on a substantially horizontal row and adapted to activate a corresponding number of maneuvering means, e.g. hydraulic valve piston rods which determine the functions of the work tool, wherein the control elements of the two assemblies are connected in pairs in such a way that a given actuator will be actuated, whether or not it is one element of a pair of elements cooperating with it, which are manually operated.
Dobbeltreguleringer af ovennævnte slags er almindeligt forekommen-15 de i det mindste ved store og middelstore kraner af den type, som er monteret umiddelbart bag ved førekabinen på køretøjer, som f.eks. lastbiler. I praksis kan hvert reguleringsaggregat have fire til otte enkelte reguleringselementer, som ved påvirkning af tilhørende ventilstempelstænger kan aktivere forskellige funktioner ved kranen, f.eks.Dual controls of the above kind are commonly found at least in the case of large and medium-sized cranes of the type mounted immediately behind the front cab of vehicles such as the trucks. In practice, each regulating unit may have four to eight individual regulating elements which, when actuated by associated valve piston rods, can activate various functions of the crane, e.g.
20 til drejning af kranens søjle, hævning og sænkning af en eller flere løftearme, drejning af en rotator, indtrækning af en krankrog, osv.20 for turning the crane's column, raising and lowering one or more lifting arms, rotating a rotator, pulling a crane hook, etc.
Ved hidtil kendte dobbeltreguleringer til dette formål består de forskellige reguleringselementer af drejelige håndtag, der er parvis forbundet ved hjælp af enkle stænger, der er ledvist forbundet med håndta-25 gene, og som forløber indbyrdes parallelt mellem de to reguleringsaggregater, idet de forbinder håndtag, der er anbragt lige over for hinanden i de to aggregater. Fordelen ved at arrangere disse reguleringshåndtag på en vandret - og ikke en lodret - række er, at forbindelsesstængerne samles i et vandret plan, hvilket giver en minimal byggehøj-30 de for arrangementet som helhed.In prior art double controls for this purpose, the various control elements consist of rotatable handles, which are connected in pairs by means of simple rods, which are jointly connected to the handles, and which run mutually parallel between the two control units, connecting handles, placed directly opposite each other in the two aggregates. The advantage of arranging these control levers on a horizontal - and not a vertical - row is that the connecting rods are assembled in a horizontal plane, giving a minimal build height for the event as a whole.
Når chaufføren eller kranoperatøren passer kranen, gør han det oftest fra den side af køretøjet, på hvilken føresædet er placeret.When the driver or crane operator fits the crane, he usually does so from the side of the vehicle on which the driver's seat is located.
Han kan da direkte benytte sig af det reguleringsaggregat, som er monteret nærmest den dør, fra hvilken han stiger ud af kabinen og behøver 35 ikke at gå rundt om køretøjet. I praksis anvendes det nærmest føreplads-døren befindende reguleringsaggregat sig derfor i 70-90% af samtlige anvendelsestilfælde. Dette indebærer, at føreren efter en tids anvendelse af kranen indlærer det mønster, som de forskellige håndtag i det nærmest førepiadsdøren placerede reguleringsaggregat danner indbyrdes.He can then directly use the control unit mounted closest to the door from which he exits the cabin and does not have to go around the vehicle. In practice, the control unit located closest to the driver's door is therefore used in 70-90% of all use cases. This means that after a period of use of the crane, the driver learns the pattern formed by the various handles in the control unit located closest to the driver's door.
Dette mønster bliver sædvanligvis så tilvant, at operatøren kan manøv- 2 150899 rere kranen tilforladeligt, uden at behøve at tænke mere indgående over hvert enkelt manøvregreb. Det er åbenbart, hvad denne ensidige indlæring betyder i de relativt få tilfælde, hvor operatøren er tvunget til at anvende det reguleringsaggregat, der er placeret på køretøjets 5 modsatte side. Da lige overfor hinanden placerede reguleringshåndtag i de to aggregater er parvist forbundne med hinanden, omskiftes det mønster, som håndtagene danner indbyrdes, således at funktionen hos f.eks. håndtaget længst til venstre i den ene række af håndtag set fra køretøjets ene side genfindes hos håndtaget længst til højre i den række 10 håndtag, som betragtes fra køretøjets modsatte side og omvendt. Dette medfører, at operatøren har betydeligt sværere ved at arbejde med det reguleringsaggregat, som befinder sig på den modsat førepladsen placerede side af køretøjet, og at han i vanskelige situationer let kan komme til at udføre fejlagtigt håndgreb, hvilket på sin side kan med-15 føre alvorlige farlige situationer.This pattern is usually used so that the operator can reliably operate the crane without having to think more thoroughly about each maneuver handle. Clearly, this is what this one-sided learning means in the relatively few cases where the operator is forced to use the control unit located on the opposite side of the vehicle 5. Since control levers placed directly opposite each other are paired with each other in pairs, the pattern formed by the levers is interchanged so that the function of e.g. the handle on the far left in one row of handles seen from one side of the vehicle is found on the handle on the far right in the row of 10 handles which are considered from the opposite side of the vehicle and vice versa. This means that the operator has a much harder time working with the regulator located on the opposite side of the vehicle and that in difficult situations he can easily make incorrect handles, which in turn can cause lead to serious dangerous situations.
Det er formålet med den foreliggende opfindelse at fjerne ovennævnte ulemper ved hidtil kendte dobbeltkommandomekanismer af denne slags og tilvejebringe en mekanisme, hvormed operatøren kan arbejde på en stedse tilforladelig måde uafhængigt af, hvilket reguleringsaggregat 20 han anvender. Dette opnås ved konstruktionen ifølge opfindelsen, som er kendetegnet ved, at hvert reguleringselement, der er placeret i en givet numerisk stilling fra det forreste element i det ene aggregat, er forbundet med et reguleringselement, der indgår i det andet aggregat, og som har samme numeriske stilling men regnet fra det bageste 25 element i dette aggregat på en sådan måde, at de to med et fælles manøvreorgan samvirkende reguleringselementer får samme stilling i forhold til de øvrige elementer i en elementrække, uanset fra hvilken side af køretøjet denne række betragtes.It is the object of the present invention to remove the above-mentioned drawbacks of prior art dual command mechanisms of this kind and to provide a mechanism by which the operator can operate in an ever reliably manner independent of the control unit 20 he employs. This is achieved by the construction according to the invention, characterized in that each control element located in a given numerical position from the front element of one assembly is connected to a control element included in the other assembly and having the same numerical position but calculated from the rear element of this assembly in such a way that the two control elements cooperating with a common actuator are given the same position with respect to the other elements in an element row, regardless of which side of the vehicle this row is considered.
De to reguleringselementer i et givet elementpar, der samvirker 30 med et fælles manøvreorgan, kan ifølge opfindelsen med fordel være indbyrdes forbundne ved hjælp af et langstrakt forbindelsesorgan, hvorved forbindelsesorganerne til de forskellige elementpar krydser hinanden i et punkt, der er beliggende omtrent midt mellem de to reguleringsaggregater.According to the invention, the two control elements of a given element pair cooperating with a common actuator may advantageously be interconnected by means of an elongate connecting means, whereby the connecting means for the different element pairs intersect at a point located approximately midway between the two control units.
35 Dobbeltreguleringen ifølge den foreliggende opfindelse vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, hvor fig. 1 viser et perspektivisk billede af en krankonstruktion, der er monteret på et køretøj, og som omfatter en dob- 3 150899 bel tregulering ifølge den foreliggende opfindelse, fig. 2 et sidebillede af en dobbeltreguleringsmekanisme ifølge den foreliggende opfindelse, fig. 3 et planbillede set ovenfra af samme mekanisme, 5 fig. 4 et forstørret sidebillede af detaljen længst til venstre i fig. 2, fig. 5 et lignende forstørret sidebillede af detaljen længst til højre i fig. 2, fig. 6 et forstørret sidebi 11ede af midterdelen af den i fig. 2 10 viste dobbeltreguleringsmekanisme, fig. 7 et forstørret plansnit gennem en detalje i mekanismen ifølge den foreliggende opfindelse, fig. 8 et perspektivisk billede af en frigjort dobbeltregulering ifølge den foreliggende opfindelse, og 15 fig. 9 et forstørret perspektivisk billede af et forbindelsesor gan, der indgår i denne.The dual control according to the present invention will then be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 is a perspective view of a crane assembly mounted on a vehicle comprising a double beam control according to the present invention; FIG. 2 is a side view of a dual control mechanism according to the present invention; FIG. 3 is a top plan view of the same mechanism; FIG. 4 is an enlarged side view of the detail on the far left of FIG. 2, FIG. 5 shows a similar enlarged side view of the detail at the far right of FIG. 2, FIG. 6 is an enlarged side elevation 11 of the middle portion of the one shown in FIG. 2 10, the control mechanism shown in FIG. 7 is an enlarged plan view through a detail of the mechanism of the present invention; 8 is a perspective view of a released dual control of the present invention; and FIG. 9 is an enlarged perspective view of a connector included therein.
I fig. 1 betegner 1 generelt en krankonstruktion, der på kendt måde er monteret på et køretøj i form af en lastbil 2. I krankonstruktionen indgår der foruden en understøtning 3 med to støtteben 4 till i-20 ge en ifølge opfindelsen udført dobbeltregulering, hvis to regulerings-aggregater er antydet ved 5 respektivt 6. I hvert sådant reguleringsaggregat 5,6 indgår der i det viste eksempel seks enkelte reguleringselementer, der ved en manuel påvirkning kan igangsætte et lignende antal funktioner ved kranen, som f.eks. drejning af kranens søjle, 25 vipning af en vippearm, hævning og sænkning af en løftearm, udskydning af forlængerarm, drejning og manøvrering af løfteredskab, osv.In FIG. 1, 1 generally denotes a crane structure which is known in a manner mounted on a vehicle in the form of a truck 2. The crane structure includes, in addition to a support 3 with two support legs 4 to 20, a double regulation made according to the invention, the two of which are regulated. Aggregates are indicated by 5 and 6, respectively. In each such regulator 5,6, the example shown includes six individual control elements which, by a manual actuation, can initiate a similar number of functions at the crane, e.g. turning the crane column, tilting a rocker arm, raising and lowering a lifting arm, extending the extension arm, turning and maneuvering the lifting gear, etc.
Herefter henvises til fig. 2-9, der mere detaljeret illustrerer selve dobbeltreguleringen ifølge den foreliggende opfindelse. Således som det fremgår af fig. 2 og 3, består såvel de enkelte reguleringsele-30 menter 7 i aggregatet 5 som de tilsvarende elementer 8 i aggregatet 6 af håndtag, der er drejeligt monteret på den nedenfor nærmere beskrevne måde. Disse håndtag 7,8 er parvist forbundne med hinanden via forbindelsesorganer 9 i form af trækelementer.Referring now to FIG. 2-9, illustrating in more detail the double regulation itself of the present invention. As shown in FIG. 2 and 3, both the individual control elements 7 of the assembly 5 and the corresponding elements 8 of the assembly 6 consist of handles which are pivotally mounted in the manner described below. These handles 7,8 are paired with each other via connecting means 9 in the form of pulling elements.
I fig. 4 og 8 er der tydeligst vist, hvorledes håndtagene 7 i ag-35 gregatet 5 er drejeligt lejret med en fælles aksel 10, der er understøttet mellem to sidestykker 11, som er nedragende fra en vinkel formet fastgørelsesplade 12, som på sin side er fastgjort på undersiden af nævnte understøtning 3 til krankonstruktionen 1. Hvert håndtag har ved sin med akslen 10 forbundne ende en gaffel 13, der mellem sine to 4 150899 ben 4 (se tillige fig. 7) understøtter en omdrejningstap 15, der er tilvejebragt et vist niveau oven over akslen 10, og ved hjælp af hvilken forbindelsesorganet 9 er ledvis forbundet.In FIG. 4 and 8, it is most clearly shown how the handles 7 of the aggregate 5 are pivotally mounted with a common shaft 10 supported between two side pieces 11 which are projecting from an angular fastening plate 12 which in turn is fastened on the underside of said support 3 for the crane structure 1. Each handle has at its end connected to the shaft 10 a fork 13 which supports between its two 4 legs (see also Fig. 7) a pivot 15 provided a certain level above the shaft 10 and by means of which the connecting means 9 is connected articulately.
Fra fig. 5 og 8 i kombination fremgår det, at der i forbindelse 5 med reguleringsaggregatet 6 er forbundet et hus 16, som indeholder et antal styreventiler, som svarer til antallet af reguleringshåndtag, og som hver for sig er påvirkelige af enkelte manøvreorganer i form af stempel stænger 17, der stikker ud fra huset. Disse stempel stænger kan med fordel være fjederbelastede eller på anden måde være tilvejebragt 10 således, at de indtager en neutral- eller hvil esti 11ing, såfremt de ikke påvirkes på manuel måde af nævnte reguleringshåndtag. Det enkelte håndtag 8, der ingår i aggregatet 6, er stift forbundet med en basisdel 18, som er drejeligt forbundet med huset 16 via et første led 19. Den tilhørende ventilstempelstang 17 er ledvist forbundet med basisdelen 15 18 via et andet led 20, som er beliggende i et niveau oven over det første led 19. Et tredie led 21 forbinder basisdelen 18 med det tilhørende forbindelsesorgan 9. Dette tredie led 21 er beliggende på et niveau under det første led 19. Af ovenstående beskrivelse fremgår det, at en nedsvingning af en af håndtagene 7,8 i samme par håndtag 20 medfører, at stempelstangen 17 trækkes i en retning ud af huset 16 og derved åbner en tilsvarende ventil inden i dette af hensyn til en aktivering af ønsket kranfunktion.From FIG. 5 and 8 in combination, it appears that in connection 5 with the regulator assembly 6, there is connected a housing 16 which contains a number of control valves corresponding to the number of control levers and which are individually actuated by individual actuators in the form of piston rods. 17, protruding from the housing. These piston rods may advantageously be spring loaded or otherwise provided 10 such that they take a neutral or resting position if they are not manually actuated by said control handle. The individual handle 8 included in the assembly 6 is rigidly connected to a base member 18 which is pivotally connected to the housing 16 via a first link 19. The associated valve piston rod 17 is connected jointly to the base member 15 18 via a second link 20 which is located at a level above the first link 19. A third link 21 connects the base member 18 with the associated connector 9. This third link 21 is located at a level below the first link 19. From the above description, it appears that a one of the handles 7,8 in the same pair of handles 20 causes the piston rod 17 to be pulled in one direction out of the housing 16, thereby opening a corresponding valve within it for the purpose of activating the desired crane function.
Der henvises nu igen til fig. 3, som anskueliggør, hvorledes forbindelsesorganerne 9 ifølge den foreliggende opfindelse er arrangeret, 25 således at de krydser hinanden i et punkt 22, der er beliggende omtrent midt mellem de to aggregater 5,6. Dette arrangement indebærer, at det forreste håndtag 7A i aggregatet 5 udgør et par med det bageste håndtag 8A i aggregatet 6, at det næstforreste håndtag 7B i aggregatet 5 udgør et par med det næstsidste håndtag 8B i aggregatet 6, osv., hvi1 -30 ket på sin side betyder, at de to håndtag (f.eks. 7B og 8B), der samvirker med en og samme ventilstempelstang 17B, altid får samme stilling i forhold til de øvrige håndtag, uanset om mønstret af håndtag betragtes fra køretøjets venstre eller højre side. Kranoperatøren kan således indlære et håndtagsmønster, som er helt identisk på begge sider af 35 køretøjet, hvorfor han ikke behøver at tænke på, om han skifter fra det ene reguleringsaggregat til det andet.Referring now to FIG. 3, which illustrates how the connecting means 9 of the present invention are arranged so that they intersect at a point 22 located approximately midway between the two assemblies 5,6. This arrangement implies that the front handle 7A of the assembly 5 constitutes a pair with the rear handle 8A of the assembly 6, that the second front handle 7B of the assembly 5 constitutes a pair with the last-last handle 8B of the assembly 6, etc. ket, in turn, means that the two handles (e.g., 7B and 8B), which cooperate with the same valve piston rod 17B, always have the same position relative to the other handles, regardless of whether the pattern of handles is considered from the left of the vehicle or right side. The crane operator can thus learn a handle pattern that is completely identical on both sides of the vehicle, so he does not have to think about switching from one control unit to the other.
Ifølge en foretrukken udførelsesform for den foreliggende opfindelse består forbindelsesorganerne 9 af rør, der er gjort flade i området ved krydsningspunktet 22. Samtlige forbindelsesrør 9, der strækker sig 5 150899 mellem de to reguleringsaggregater 5,6, har hensigtsmæssigt eksakt samme standardlængde og -form. Et sådant rør er illustreret i forstørret målestok i fig. 9, og det udfladede område ved rørets midte er betegnet med 23. Eftersom afstanden mellem f.eks. håndtagene 7 A og 8A 5 ikke er den samme som afstanden mellem håndtagene 7B og 8B, er det ikke muligt at tilslutte sådanne standardrør 9 direkte til de forskellige håndtags omdrejningstappe 15, uden at dette sker ved hjælp af særlige forbindelsesdele 24, således som vist mere detaljeret i fig.According to a preferred embodiment of the present invention, the connecting means 9 consist of tubes made flat in the region at the intersection point 22. All connecting tubes 9 extending between the two control assemblies 5,6 suitably have exactly the same standard length and shape. Such a tube is illustrated on an enlarged scale in FIG. 9, and the flattened area at the center of the tube is indicated by 23. Since the distance between e.g. While the handles 7A and 8A 5 are not the same as the distance between the handles 7B and 8B, it is not possible to connect such standard tubes 9 directly to the rotary pins 15 of the various handles without this being done by means of special connecting parts 24, as shown more detailed in FIG.
7. Hver sådan forbindelsesdel 24 består af en tap, der på teleskopisk 10 måde kan indføres i enden af røret 9, og som kan fastgøres i forhold til røret ved hjælp af en skrue 25, der via et hul strækker sig gennem røret, og som går igennem et aflangt slidsformet hul 26 i forbi ndel ses-delen 24. Ved spænding af en møtrik 27 på skruen 25 bliver forbindelsesdelen 24 stift forbundet med røret 9, hvorved forbindelsesdelen 24 15 på grund af det aflange hul 26 skydes ulige langt ind i røret afhængigt af den aktuelle afstand mellem omdrejningstappene 15 for håndtagene 7,8 i et samhørende par. Ved sin ene ende, der er rettet bort fra røret 9, har forbindelsesdelen 24 en indsnævret del, hvori der er udskåret et i alt væsentligt cirkulært hul 28, hvori der er anbragt et i det 20 mindste delvis sfærisk legeme 29, som er lejret på omdrejningstappen 15. Gennem dette arrangement tillades en svingning af forbindelsesrøret 9 ikke alene i et lodret plan i forhold til omdrejningstappen 15, men også i det vandrette plan, hvilket er nødvendigt, idet forbindelsesrøret forløber under en vis vinkel i forhold til det lodrette plan, hvor-25 i håndtaget 9 bevæges ved svingning.7. Each such connecting portion 24 consists of a pin which can be telescopically inserted into the end of the tube 9 and which can be secured to the tube by a screw 25 extending through a hole through the tube and which passes through an elongated slit-shaped hole 26 past the portion 24. Upon tightening a nut 27 on the screw 25, the connecting portion 24 is rigidly connected to the tube 9, whereby the connecting portion 24 15 due to the elongate hole 26 is pushed oddly far into the tube. depending on the actual distance between the pivots 15 of the handles 7,8 in a pair of pairs. At its one end, which is directed away from the tube 9, the connecting portion 24 has a narrowed portion in which is cut a substantially circular hole 28, in which is arranged at least a partially spherical body 29, which is mounted on This pivot 15. Through this arrangement, a pivot of the connecting tube 9 is allowed not only in a vertical plane with respect to the pivot 15, but also in the horizontal plane, which is necessary, the connecting pipe extending at a certain angle with respect to the vertical plane, where -25 in handle 9 is moved by oscillation.
For at de forbindelsesrør 9, som krydser hinanden i punktet 22, ikke skal fastkiles ved påvirkning af nævnte manøvrehåndtag, og for at de forholdsvis lange og slanke rør ikke skal bøjes ned, er disse ved punktet 22 understøttet af en holder 30, der omfatter et antal tynde 30 mellemlæg 31 af et materiale med lav friktionskoefficient, f.eks. nylon, hvorved de udfladede rørdele 23 er anbragt mellem et par sådanne mellemlæg 31. I praksis kan holderen 30 fordelagtigt bestå af en U-for-met krop, der er anbragt på undersiden af understøtningen 3 med mellem-læggene 31 udstrakt vandret mellem kroppens to lodrette grene.In order that the connecting pipes 9 which intersect at the point 22 are not to be wedged by the actuation of said maneuvering handle and that the relatively long and slender pipes are not bent down, at the point 22 these are supported by a holder 30 comprising a number of thin layers 30 of a material having a low coefficient of friction, e.g. nylon, whereby the flattened pipe portions 23 are disposed between a pair of such shims 31. In practice, the holder 30 may advantageously consist of a U-shaped body disposed on the underside of the support 3 with the shims 31 extending horizontally between the two bodies. vertical branches.
35 Det er givet at opfindelsen ikke alene er begrænset til den be skrevne og på tegningerne viste udførelsesform. Således er det muligt at anvende andre forbindelser i stedet for rør eller andre stive forbindelsesorganer mellem de respektive håndtag, f.eks. kan der anvendes fleksible elementer, såsom wirer eller eventuelt ledninger for hydrau- 6 150899 li sk væske, ved hjælp af hvilke en håndtagsbevægelse kan overføres til det andet håndtag i samme par. Endvidere er dobbeltreguleringen ifølge den foreliggende opfindelse anvendelig ikke alene i forbindelse med kraner, men også i kombination med andre vilkårlige arbejdsredskaber, 5 der kræver to med afstand fra hinanden anbragte reguleringsaggregater af den beskrevne slags. Som reguleringselementer kan der ligeledes forekomme andre elementer end lige netop håndtag, f.eks. trykknapper eller skydere. Endvidere skal det bemærkes, at det ene reguleringsaggregat, i særdeleshed det aggregat, som er forbundet med ventilhuset 10 16, selvfølgelig kan have flere reguleringselementer end det andet aggregat, nemlig i det tilfælde, hvor de overtallige reguleringselementer ikke nødvendigvis behøver at kunne dobbeltreguleres.It is to be understood that the invention is not limited to the embodiment described and shown in the drawings. Thus, it is possible to use other connections instead of pipes or other rigid connecting means between the respective handles, e.g. For example, flexible elements, such as wires or possibly hydraulic fluid wires, may be used by which one handle movement may be transferred to the other handle in the same pair. Furthermore, the double control of the present invention is applicable not only in the case of cranes, but also in combination with any other working tools requiring two spacers of the type described. As control elements, elements other than just handles can also occur, e.g. push buttons or sliders. Furthermore, it should be noted that one control unit, in particular the unit connected to the valve housing 10 16, may of course have more control elements than the other unit, namely in the case where the excess control elements do not necessarily have to be double-regulated.
