Description
Hubbalken fur Einschienenhängebahnen im UntertagebetriebLifting beam for monorails in underground operation
Beschreibungdescription
Fur den Transport von Behältern sind vor der Einführung der Hubbalken zwei gekuppelte Laufkatzen mit je einem Hubzug benutzt worden ( s. Skizze T ). Diese Anosbusg hatte jedoch den Nachteil, dass die Bedienung entweder von zvei Personen oder intervallmässig vorgenommen ve* ien musste, was besonders bei der Verwendung von Druckluftaufsteckmotoren sehr unpraktikabel war.For the transport of containers are in front of the introduction of the lifting beam two coupled trolleys, each with a hoist, were used (see sketch T). However, this Anosbusg had the disadvantage that the operation had to be done either by two people or at intervals, which is very impractical, especially when using pneumatic motors was.
Aus diesem Grunde wurden die Hubbalken entwickelt, bei denen über einen zentralen Hubzug beide Lasthaken zugleich angehoben werden ( s. Skizze 2). Diese Konstruktionen sind jedoch verh'ältnismassig teuer, da neue zweistrangige Hubwerke erforderlich waren, die wegen der geringen Stuckzahlen relativ teuer sind.For this reason, the walking beams were developed in which one central hoist both load hooks are raised at the same time (see sketch 2). However, these constructions are relatively expensive because they are new two-legged ones Hoists were required, which are relatively expensive because of the low number of pieces.
Erfindungsgeraass wird daher ein Hubbalken vorgeschlagen, dessen Hubwerk ganzlich aus vorhandenen Serienteilen zusammengesetzt ist ( s. Skizze 5). Unter den gegebenen Voraussetzungen, dass I. die Hubgeschwindigkeit zur Konstanthaltung des Antriebsdrahmomentes ohnehin auf die Hälfte reduziert werden nuss, was auch wegen der vorhandenen Druckluftmotoren erforderlich ist, dass 2. die Hubbalken üblicherweise eine Lange von mindestens 3 m haben, und dass*.5. die notwendige Hubhohe nicht mehr als etwa 2 m betragt, kann folgende eiiüfache Bauart benutzt werden ( s. Skizze 3)ϊ Ein normaler Serienhubzug (i) wird horizontal an einem Ende des Hubbalkens befestigt. Seine Hubkraft wird mit einer Unterflasche (2), die in der Längsachse des Balkens lauft, auf den doppelten Wert gebracht. An der Unterflasche werden die beiden Hubketten (3) befestigt, die durch die Umlenkrollen (U) umgelenkt werden. Um Schwierigkeiten bei der Betätigung des unbelasteten Hubbalkens zu vermeiden, kann die Unterflasche gegebenenfalls mit einer einfachen einmal umgelenkten Giommibandfeder (5) vorgespannt werden, wenn die Lasthaken nicht mit einem Hilfsgewicht ausgerüstet veräen können.According to the invention, a lifting beam is therefore proposed, the lifting mechanism of which is composed entirely of existing series parts (see sketch 5). Under the given conditions that I. the lifting speed to keep the drive torque constant is reduced by half anyway become nut, which is also necessary because of the existing air motors is that 2. the walking beam is usually at least 3 m long have, and that * .5. the necessary lifting height does not exceed about 2 m, The following simple design can be used (see sketch 3) ϊ A normal series hoist (i) is horizontal at one end of the walking beam attached. Its lifting force is doubled with a bottom block (2) that runs in the longitudinal axis of the beam. At the The two lifting chains (3) are attached to the bottom block, which are supported by the Deflection rollers (U) are deflected. In order to avoid difficulties in operating the unloaded lifting beam, the bottom block can, if necessary pretensioned with a simple Giommi band spring (5) that has been deflected once if the load hook is not equipped with an auxiliary weight can dispose of.
