Opis patentowy opublikowano: 20.01.1984 121495 Int. Cl» B66C 1/14 Twórca wynalazku :— Uprawniony z patentu: BLOHM+VOSS AG, Hamburg (Republika Federalna Niemiec) Trawersa do dzwignic Wynalazek dotyczy trawersy do dzwignic, skla¬ dajacej sie z dwóch usytuowanych obok siebie dwuteowych dzwigarów majacych na swych kon¬ cach zwrócone do srodka wneki, z san nosnych umieszczonych miedzy dzwigarami w odstepie od siebie, przesuwnych wzdluz dzwigarów, slizgaja¬ cych sie na swych plozach we wnekach na szynach.Znane sa powyzszego rodzaju trawersy dla dzwignic, w których sanie nosne biegna na szy¬ nach umieszczonych na wewnetrznych stronach dwuteowych dzwigarów na dolnych lub górnych ich pasach.W pierwszym wykonaniu trawersy, gdy sanie nosne biegna na wewnetrznych stronach dzwiga¬ rów na dolnych ich pasach, powstaja dodatkowe naprezenia w dzwigarach z uwagi na powstale mimosrodowe przylozenie obciazenia. Na skutek tego musza byc podparte w krótkich odstepach wezlowkami. Uklad ten ma ponadto te wade, ze montaz san — które sa rozbieralne na trawersie i które musza byc montowane w koncowym ob¬ szarze miedzy dzwigarami — sprawia duzo trud¬ nosci.W drugim przykladzie trawersy, gdy sanie no¬ sne biegna na wewnetrznych stronach dzwigarów, na górnych ich pasach, zmniejszone zostaja wpra¬ wdzie dodatkowe naprezenia powstale przez mi¬ mosrodowe przylozenie obciazenia, jednakze tra- 10 15 20 25 30 z \ wersa ta musi miec duza wysokosc, aby nie na¬ stapila utrata jej statycznosci (przez niedokladne regulowanie, lub przez zmieniajacy sie punkt ciez¬ kosci obciazenia, na przyklad cieczy). Calkowite zabezpieczenie trawersy przed jej przechyleniem wyznaczone zostaje okreslonym odstepem miedzy punktem zawieszenia trawersy i punktem przylo¬ zenia obciazenia.W przypadku trawersy wedlug drugiego przy¬ kladu wykonania zwiekszona wysokosc trawersy zapewniajaca jej niewywracalnosc równoczesnie niekorzystanie powoduje zmniejszenie wysokosci podnoszenia dzwignicy. Nastepna wada trawersy wedlug drugiego przykladu wykonania polega na tym, ze trzepien lezy swobodnie lub musi byc do¬ datkowo chroniony.Zadaniem wynalazku jest wyeliminowanie wy¬ zej wymienionych wad i niedogodnosci.Istota trawersy wedlug wynalazku polega na tym, ze kazde z san nosnych posiada osobny trz¬ pien do ich przesuwu usytuowany wewnatrz tra¬ wersy wzdluznie miedzy dzwigarami, a 'wneki w których biegna (slizgaja sie) plozy san nosnych usytuowane sa mniej wiecej w linii osi bezwlad¬ nosci dwóch •stojacych na sztorc dzwigarów, przy czym wneki na koncach dzwigarów sa od góry otwarte na dlugosci san nosnych.Ponadto trawersa wedlug wynalazku charakte¬ ryzuje sie tym, ze do zawieszenia haków lub pa- 121 4953 laków na saniach ma dwa wieszaki zaopatrzone w stoper wspóldzialajacy z górnym ogranicznikiem wneki i ma walcowe czopy umieszczone we wzdluznych otworach wieszaków.Osobne trzpienie umozliwiaja przesuwanie san nosnych niezaleznie od siebie.Dzieki takiemu usytuowaniu wnek, w których slizgaja sie plozy san nosnych w linii osi bez¬ wladnosci dzwigarów — odpadaja ramy przeszka¬ dzajace wyginanie sie sredników i przy tym zos¬ taja zmniejszone dodatkowe naprezenia. Przy tym nie jest wymagane podparcie szyn w krótkich od¬ stepach przez wezlówki, poniewaz szyny sa ulo¬ zone osiowo.Aby montujac na gotowo sanie nosne mozna je bylo wstawic z góry, górna czesc dzwigary jest krótsza niz dolna jego czesc.Dzieki usytuowaniu trzpienia do przesuwu san nosnych wewnatrz trawersy wdluznie miedzy dzwigarami trawersy, nie jest on narazony na uszkodzenia i przez to nie wymaga on speecjal- nego zabezpieczenia. v Trawersa wedlug wynalazku dzieki przedsta¬ wionemu rozwiazaniu.posiada maly ciezar wlasny w stosunku do swej wysokosci, a nadzór san nos¬ nych jest znacznie ulatwiony dzieki dobremu do¬ stepowi i udoskonalonej konstrukcji.W przypadku zatrzymywania trawersy dochodzi do uszkodzen trzpieni przez haki lub palakl nos¬ ne, które naciskaja na trzpienie z góry, kiedy znajduja sie one na spodzie. Takie uszkodzenia trzpienia ograniczone sa przez opisane rozmiesz¬ czeni otworów wzdluznych w wieszakach haków lub polaków nosnych zawieszonych na saniach nosnych. Dzieki temu wieszaki moga sie przesu¬ wac w góre niezaleznie od trzpienia, dopóki nie zderza sie wraz ze stoperami przy konstrukcji trawersy.Przedmiot wynalazku jest przedstawiony w przy¬ kladzie wykonania na rysunku, na którym fig. 1 przedstawia trawerse, w przekroju wzdluznym; fig. 2 — trawerse wedlug fig. 1, w przekroju po¬ przecznym; fig. 3 — trawerse wedlug fig. 2, w po¬ wiekszeniu; a fig. 4 — wieszak palaka nosnego, w widoku z boku. 1 495 4 We wnekach 1 dzwigarów 2 majacych w prze¬ kroju poprzecznym ksztalt dwuteowników, ru¬ chem slizgowym po szynach 3 usytuowanych cen- trycznie wzgledem sredników dzwigarów 2 prze- s suwaja sie swoimi plozami 4 sanie 5. Palak nosny 6 jest zamocowany na saniach nosnych 5 za pomo¬ ca wieszaka 9. Na plozach 4 jest osadzone loze 7 przez które przebiega trzpien 8. Na czopach 14 plóz 4, w których znajduje sie loze 7 trzpienia 8. 10 osadzone sa wieszaki 9 dla palaków 6, wychylne ciazone w kierunku^ dolu do góry i w nastep- wokól osi 11 san nosnych 5.Przy odsuwaniu trawersy wieszaki 9 zostaja ob- ciazane w kierunku z dolu dovgóry i w nastep- 15 stwie tego wieszaki 9 moga byc wychylane do góry dzieki ukladowi wzdluznemu otworowi 13. Ten ruch odchylny nastepuje przez stopery 10, które uderzaja o górny ogranicznik 12 wneki 1 do stanu bezruchu. Osiaga sie dzieki temu zniwelowanie 20 uszkodzenia trzpienia 8. PL PL PL PL PLThe patent description was published: January 20, 1984 121495 Int. Cl »B66C 1/14 Inventor: - Authorized by the patent: BLOHM + VOSS AG, Hamburg (Federal Republic of Germany) Crossbeam for cranes The invention concerns a crossbeam for cranes, consisting of two I-beam girders situated next to each other, with recesses facing inwards at their ends, with load-bearing slides placed between the girders at a distance from each other, sliding along the girders, sliding on their skids in the recesses on the rails. in which the carrying sled runs on rails placed on the inner sides of the I-beam girders on their lower or upper chords. In the first version of the traverse, when the carrying sled runs on the inner sides of the spars on their lower chords, additional stresses arise in the spars due to on the resulting eccentric load application. As a result, they must be supported at short intervals with knots. This arrangement also has the disadvantage that the installation of the sleds - which are detachable on the crossbeam and which must be mounted in the end area between the girders - is very difficult. on their upper strips, the additional stresses caused by the application of the load in the center are reduced, but the latter must have a great height in order not to lose its stability (due to inaccurate adjustment of the load). , or by changing the point of gravity of the load, for example a fluid). The total protection of the cross-beam against tilting is determined by a specific distance between the cross-beam suspension point and the load application point. In the case of a cross-beam, according to the second embodiment, the increased height of the cross-beam, ensuring its invulnerability, at the same time disadvantageously reduces the lifting height of the crane. Another disadvantage of the traverse according to the second embodiment is that the shank lies freely or must be additionally protected. The object of the invention is to eliminate the above-mentioned drawbacks and inconveniences. The essence of the traverse according to the invention consists in the fact that each of the slings has a separate The shafts for their movement are located inside the beam longitudinally between the girders, and the recesses in which the runners run (slide) are located approximately in the line of the axis of inertia of the two girders standing upright, with the recesses at the ends The girders are open at the top to the length of the slings. Moreover, the traverse according to the invention is characterized by the fact that for hanging hooks or parapets 4953 on a sledge it has two hangers provided with a stopper that interacts with the upper stop of the recess and has cylindrical pivots placed in the longitudinal The separate pins enable the slings to be moved independently of each other. h slides of the carrier slides slide along the axis of inertia of the spars - the frames that prevent bending of the diameters fall off and at the same time additional stresses are reduced. It is not necessary to support the rails in the short steps by the tie rods, as the rails are axially aligned. In order to be able to insert the sled ready to install it from above, the upper part of the spar is shorter than the lower part. sliding of the load-bearing bars inside the traverse between the traverses of the traverse, it is not exposed to damage and therefore does not require special protection. The traverse according to the invention, thanks to the presented solution, has a low own weight in relation to its height, and the supervision of the load-bearing slings is significantly facilitated by a good step and improved construction. bearers that press against the pins from above when they are at the bottom. Such damage to the mandrel is limited by the described arrangement of the longitudinal holes in the hangers of hooks or load poles suspended on a sledge. As a result, the hangers are able to slide upwards independently of the mandrel until they collide with the stoppers on the construction of the traverse. The subject of the invention is illustrated by an exemplary embodiment in the drawing, in which Fig. 1 shows the traverse in longitudinal section; FIG. 2 shows a cross section according to FIG. 1; Fig. 3 shows the traverse according to Fig. 2, in a larger scale; and Fig. 4 shows a crosspiece hanger in a side view. 1 495 4 In the recesses 1 of the girders 2 with the cross-sectional shape of I-sections, the sliding movement on the rails 3 located centrally in relation to the diameters of the girders 2, the slides slide with their skids 4, the sledge 5. The carrying pile 6 is mounted on a sledge. supports 5 by means of a hanger 9. On the skids 4 there is a bed 7 through which the mandrel 8 runs. On the trunnions 14 of the skins 4, in which there is a bed 7 of the mandrel 8. 10 hangers 9 for bunkers 6 are mounted, tilted towards ^ downwards and then around the axis 11 of the trolley 5. When the traverse is moved away, the hangers 9 are loaded from the bottom upwards and, consequently, the hangers 9 can be swung upwards thanks to the oblong opening 13. This pivoting movement it is carried out by stoppers 10 which strike the upper stop 12 of the cavity 1 to a standstill. This will help to compensate for 20 damage to the stem 8. PL PL PL PL PL PL
