Opfindelsen angår et kranhejseværk af den i indledningen til krav 1 angivne art.The invention relates to a crane hoist of the kind specified in the preamble of claim 1.
Et kranhejseværk af denne art er kendt fra beskrivelsen til DE patentskrift nr. 302 023. Her er bæredelens gaffel 5 med henblik på udsvingning af tovstyretrissen lejret i to fjedrende plader, hvis længst borte fra trissen liggende ender er fastgjort i et firkantet rørstykke, hvori skruerne ved udsvingning af pladerne forskydes i slidser i disse.A crane hoist of this kind is known from the specification of DE Patent Specification No. 302 023. Here, the fork 5 of the support member for swinging the rope guide pulley is mounted in two resilient plates, the longest distant ends of the pulley being fixed in a square pipe piece in which the screws in the case of oscillation of the plates, slots in them are displaced.
Det firkantede rør går foroven over i et cylindrisk rørstyk-10 ke, der er drejeligt lejret i to kuglelejer anbragt i vertikal afstand fra hinanden.The square tube goes to the top of a cylindrical tube piece that is pivotally mounted in two ball bearings spaced vertically apart.
Udformningen og fastgørelsen af pladerne samt den pladsoptagende lejringsanordning til svingning af udliggeren er en ulempe ved denne konstruktion. Pladerne er således 15 udsat for vekslende bøjningspåvirkninger, og som følge af forskydningsbevægelserne ved pladernes udsvingning i sideretningen slides pladerne, det firkantede rør og skruerne.The design and fastening of the plates as well as the space accommodating bearing device for pivoting the boom are a disadvantage of this construction. Thus, the plates are subjected to alternate bending stresses, and as a result of the shear movements in the lateral oscillation of the plates, the plates, the square tube and the screws are worn.
Endvidere kræves et forholdsvis stort træk i tovet til at bøje pladerne med ubelastet løftekrog. Endelig er lejringen 20 af bæredelen i to kuglelejer forholdsvis dyr og pladsoptagende, idet lejringen strækker sig over en forholdsvis stor højde.Furthermore, a relatively large drag in the rope is required to bend the plates with unloaded lifting hook. Finally, the bearing 20 of the support member in two ball bearings is relatively expensive and accommodating, the bearing extending over a relatively high height.
Fra AT patentskrift nr. 306 302 kendes endvidere en tovstyreanordning med en på sin aksel aksialt uforskydelig 25 og samtidig svingbar tovstyretrisse, der er svingbar ved hjælp af et leje af kugleledtypen, hvis to lejeringe er anbragt mellem en på akselen siddende glidebøsning og væggen i boringen i tovstyretrissens nav.Further from AT Patent No. 306,302 there is known a rope control device having a ratchet axially displaceable on its shaft and at the same time pivotable rope guide pulley which is pivotable by means of a ball-type bearing, whose two bearings are arranged between a sliding sleeve on the shaft and the wall of the bore. in the rope guide pulley hub.
Disse kendte tovstyreanordninger kræver imidlertid 30 at styretrissens aksel har en forholdsvis stor diameter, idet lejeafstanden må være forholdsvis stor, fordi styretrissen skal kunne forskydes aksialt. Endvidere er udgifterne til korrosionsbeskyttelse og smøring af akselen forholdsvis høje. Endelig har de kendte styreanordninger kun begrænsede 35 anvendelsesmuligheder, da lejet ikke er egnet til høje omdrejningstal.However, these known rope control devices require that the shaft of the guide pulley has a relatively large diameter, the bearing spacing having to be relatively large because the control pulley must be able to be displaced axially. Furthermore, the cost of corrosion protection and lubrication of the shaft is relatively high. Finally, the known control devices have only limited applications, since the bearing is not suitable for high rpm.

Det er formålet med opfindelsen - under bibeholdelse af den korte afstand mellem lejerne, der bærer tovstyretrissens aksel - på billigst mulig måde at lejre bæredelen i det omhandlede kranhejseværk således, at vedligeholdelsesud-5 gifterne bliver mindst mulige og levetiden længst mulig.It is the object of the invention - while maintaining the short distance between the bearings carrying the rope guide shaft - in the cheapest way possible to camp the support part of the relevant crane hoist so that the maintenance costs are as small as possible and the longest life possible.
Dette er ifølge opfindelsen opnået ved hjælp af det i krav l's kendetegnende del anførte.This is achieved according to the invention by means of the characterizing part of claim 1.
En fordelagtig videre udvikling af kranhejseværket ifølge opfindelsen er angivet i krav 2.An advantageous further development of the crane hoist according to the invention is given in claim 2.
10 Anvendelsen af det vedligeholdelsesfrie leje og det éngangssmurte rulningsleje bevirker, at tovstyretrissen ikke kræver nævneværdigt tilsyn. Desuden er bæredelens udstrækning i højden forholdsvis lille, idet der med et enkelt leje er opnået mulighed for svingning om to, vinkelret på 15 hinanden stående, akser. Endvidere forbliver det belastede tov med sin virkelinie liggende helt i bunden af tovrillen, og den afløbende tovstrækning forbliver i systemaksen til den efterfølgende tovstyretrisse, specielt styretrissen til beskyttelse mod overbelastning.10 The use of the maintenance-free bearing and the once-lubricated rolling bearing means that the rope guide pulley does not require significant supervision. In addition, the height of the support portion is relatively small, with a single bearing being allowed to pivot about two axes perpendicular to each other. Furthermore, the loaded rope with its line of action remains completely at the bottom of the rope groove, and the draining rope stretch remains in the system axis of the subsequent rope guide pulley, especially the control pulley for protection against overload.
20 På tegningen er vist en udførelsesform for hejseværket ifølge opfindelsen, hvor fig. 1 set fra siden viser den øverste del af en tårn-svingkran, og fig. 2 trådstyretrissen og dennes ophængningsde-25 le, delvis i snit og i større målestok.20 shows an embodiment of the hoist according to the invention, in which FIG. 1 is a side view of the upper part of a tower crane, and FIG. 2 shows the wire guide pulley and its suspension parts, partly in section and on a larger scale.
Svingkranen har bl.a. en udligger 1, en kontravægtudligger 2 og en tårnspids 3.The swing crane has an outrigger 1, a counterweight outrigger 2 and a tower tip 3.
På kontravægtudliggeren 2 er anbragt en motordrevet hejsespiltromle 4. Hejsespiltromlen 4 er udformet 30 som oplagringstromle for et i flere lag opviklet krantov 5; der foreligger således en hejsespiltromle 4 med en forholdsvis stor diameter, en forholdsvis stor længde og med forholdsvis lille tovrillestigning. Krantovet 5 forløber fra hejsespiltromlen 4 over en første (nærmeste) 35 styretrisse 6, der i et niveau højere end hejsespiltrom-On the counterweight boom 2 is mounted a motorized hoisting drum 4. The hoisting drum 4 is formed 30 as a storage drum for a multi-layered crane rope 5; there is thus a hoisting drum 4 having a relatively large diameter, a relatively long length and with a relatively small rope increase. The crane rope 5 extends from the hoisting drum 4 over a first (closest) guide pulley 6 which at a level higher than the hoisting drum.

len er svingbar ophængt på stelkonstruktionen i tårnspidsen 3, og derfra fortsætter tovet over en anden, stationært anbragt styretrisse 7 nær udliggerens 1 mod tårnet vendende ende, og eventuelt over flere styretris-5 ser eller tovskiver og over krankrogtaljen hen til et fastgørelsespunkt.The rope is pivotally suspended on the frame structure of the tower tip 3, and from there the rope continues over another stationary guide roller 7 near the end of the projection 1 towards the tower, and optionally over several guide rails 5 or rope washers and over the crane hook to a point of attachment.
Den nærmest hejsespiltromlen 4 liggende tovstyre-trisse er på kendt måde ved hjælp af et rulleleje 17 lejret på en ikke drejelig aksel 8- Akselen 8 er understøt-10 tet i passende boringer i en ved denne ende 9a gaffelformet bæredel 9 eller på tilsvarende måde. Den bort fra akselen 8 vendende stangformede ende 9b af bæredelen 9 har en tværboring 10 gennem hvilken er ført en vandret bolt 11 med væsentlig mindre diameter end boringen, hvilken 15 bolt ved siderne er understøttet i udsparinger i vanger 12 eller lignende dele af tårnspidsens tre stel. Bolten 11 er fastgjort aksialt uforskydeligt.The rope guide pulley closest to the hoisting drum 4 is in a known manner supported by a roller bearing 17 mounted on a non-rotatable shaft 8- The shaft 8 is supported in suitable bores in a fork-shaped support member 9 at this end or similarly. The rod-shaped end 9b facing away from the shaft 8 has a transverse bore 10 through which is passed a horizontal bolt 11 of substantially smaller diameter than the bore, the lateral bolt being supported in recesses in bars 12 or similar portions of the three frame of the tower tip. . The bolt 11 is fastened axially displaceable.
Midt på bolten 11 er anbragt en inderring 13 i et kugleledleje, hvilken inderring har en konveks, sfæ-20 risk yderflade. Inderringen 13 er fikseret i aksial retning ved hjælp af to afstandsbøsninger 14a, 14b, som ved deres ene ende ligger an mod endefladen af inderringen 13 og ved deres anden ende støtter mod indersiden af vangen 12. En yderring 15 med cylindrisk og til dia-25 metren af tværboringen 10 tilpasset yderflade og med konkav, sfærisk inderflade griber omkring inderringen 13. Yderringen 15 er fikseret i aksial retning på i sig selv kendt måde, f.eks. ved hjælp af passende sikringsringe 16 (Seegerringe).In the middle of the bolt 11 is an inner ring 13 in a ball bearing, which inner ring has a convex spherical outer surface. The inner ring 13 is fixed in the axial direction by means of two spacer bushings 14a, 14b, which at one end abut against the end surface of the inner ring 13 and at their other end abut against the inside of the catch 12. An outer ring 15 with cylindrical and di-25 the meter of the transverse bore 10 adapted to the outer surface and with concave, spherical inner surface engages around the inner ring 13. The outer ring 15 is fixed in axial direction in a manner known per se, e.g. using appropriate securing rings 16 (Seeger rings).
30 Yderringen 15 og inderringen 13 danner et så kaldt leje af kugleledtypen (Gelenklager), som muliggør drejning af tovstyretrissen 6 om boltens 11 langsgående midterakse og en begrænset svingning af bæredelen 9, indbefattet tovstyretrissen, om en vandret akse, 35 der ligger vinkelret på boltens 11 langsgående midterakse.The outer ring 15 and the inner ring 13 form a so-called ball-type bearing (Gelenklag), which allows rotation of the rope guide pulley 6 about the longitudinal center axis of the bolt 11 and a limited pivot of the support member 9, including the rope guide pulley, about a horizontal axis 35 perpendicular to the bolt. 11 longitudinal center axis.
