Definitions

  • the invention relates to a tilting tableware for receiving and handling heavy spools or reels with a roller bracket guided in a trolley and a mandrel arranged thereon for engagement in the core bore of the roller with a radially extendable clamping jaw.
  • tilting harnesses are generally suspended from the trolley and are used to transfer goods wound on rolls, such as wires, cables, sheet metal coils, paper webs or the like, from one position to another.
  • the necessities for this arise in the course of processing such materials in a variety of ways.
  • the mandrel of the tilting gear is inserted into the core bore of the reel spool and spread there.
  • the load is then raised by lifting the trolley and it can be pivoted into a different position, generally by 90 °, by pivoting the roller bracket in the trolley.
  • the tilting harness is comparatively easy to handle.
  • the invention is therefore based on the object of designing a tilting tableware of the type mentioned at the outset in such a way that it ensures safe handling of the coils both structurally and in terms of handling which is very simple.
  • the drive for the clamping jaw actuation comprises a spring-loaded pivot lever which can be pivoted into the retracted position of the clamping jaw by an eccentric against the spring force.
  • the pivot lever has a short lever arm for engaging the clamping jaw and a long lever arm for engaging the spring force and the eccentric.
  • the mandrel engaging in the core bore of the spool or reel offers sufficient space inside for such a double lever with a short load arm and a long power arm, so that the power transmission can be adapted to the corresponding requirements within comparatively wide limits.
  • the short lever arm of the pivot lever engages with particular advantage directly in a window-like opening in the foot part of the clamping jaw, so that there is a forced guidance between the pivot lever and clamping jaw such that the clamping jaw follows every movement of the pivot lever, namely when the clamping jaw is extended into the clamping point. l'ung, as when pulling the jaw into the disengaged position.
  • the spring consists of a helical compression spring arranged in a longitudinally adjustable sleeve.
  • the pretension of the spring arranged in the sleeve and thus the force for tensioning the clamping jaw can be varied within comparatively wide limits with respect to the roll or spool to be received by the mandrel.
  • a spring arrangement which is prestressed in a pressure housing and the pressure housing engages on the lever arm and is guided so that it can be displaced without pressure across the lever arm.
  • the spring arrangement can consist of one or more helical springs, possibly also disc springs or the like. These springs are stored under preload in the pressure housing. In this case too, a device for changing the pretensioning of the springs can be provided, if necessary.
  • the displaceable mounting of the pressure housing on the roller bracket causes the pressure housing with the spring arrangement preloaded therein to follow the movement of the long lever arm caused by the eccentric.
  • the mechanical connection between the eccentric and the spring arrangement provides the invention in its further embodiment so that between the eccentric and the spring arrangement is arranged a yoke which is displaceable relative to the pressure housing, one of the pressure pieces on the eccentric and the other pressure piece within the pressure housing as an abutment for the Compression spring is arranged, wherein the pressure housing forms the other abutment for the compression spring arrangement. Due to the force of the compression spring arrangement, the one pressure piece of this yoke is generally held in firm contact with the pressure housing. To a certain extent, the pressure housing and the displaceable yoke form an unchangeable unit, as long as the long lever arm of the swivel lever follows the eccentric movement.
  • the pressure housing has a positive guide for the lever arm.
  • the pressure housing on a frame part can have a window into which the end of the pivot lever engages.
  • the pivot lever can also engage between two journals mounted on the pressure housing at a distance. In this way, there is a positive guidance between the pressure housing and the lever arm, as a result of which the pressure housing follows all the movements of the long lever arm of the swivel lever caused by the eccentric.
  • the invention further sees an automatically falling in the extended position of the clamping jaw Locking device for the swivel lever.
  • This lock does not necessarily have to act directly on the swivel lever, it can also act in the same way on the eccentric or on a part firmly connected to it.
  • This locking device can be designed with particular advantage in such a way that a locking pin, which is under the action of a tension spring and can be moved transversely to the pivoting lever or to the eccentric or a component connected to it, is provided, which in the one end position of the eccentric, that of the extended position corresponds to the clamping jaw, engages in a corresponding recess on the eccentric or on the swivel lever or the like.
  • a locking device designed in this way ensures that the pivoting lever can only be actuated when the clamping jaws are spread to pivot the roller bracket.
  • the eccentric can be connected to a locking plate which has a catch and is arranged in the movement path of a bolt which is under spring tension in the direction of engagement with respect to the catch. If the eccentric has reached its end position when the clamping jaw is actuated, the bolt falls into the catch under the force of the spring acting on it and leads to a reliable locking of the device.
  • the foot section 10 of the clamping jaw 6 is provided with an opening 11 into which the short lever arm 12 of a pivot lever 14 mounted on an axis 13 in the immediate vicinity of the clamping jaw 6 engages, the longer lever arm 15 of which is under the action of a helical compression spring 16.
  • the helical compression spring 16 is arranged in a sleeve 17, which is provided with an external thread 18 and can be screwed or unscrewed into the bearing block 19 in order to be able to adjust the biasing spring 16 by shortening the reversing compression spring 16 accordingly and thus the spring force with which - by the lever ratio of the Swivel lever 14 translated - the clamping jaw 6 is pressed radially outward into its clamping position.
  • an eccentric cam 20 is fastened on a shaft 21 which is provided with a hand lever 22 which pivots the eccentric 20 between the position shown in FIG. 1, in which the swivel lever 14 is below the effect of the helical compression spring 16 is shifted outwards into the clamping position and the position according to FIG. 2 is adjustable, in which the pivot lever 20 has been pivoted by the eccentric against the force of the helical compression spring 16, so that it moves the clamping jaws 6 into the The mandrel 4 has retracted the retracted position.
  • the eccentric 20 is fixedly connected to a locking plate 23 which has a locking recess 24 which, in the pivoted position according to FIG.
  • FIGS. 5 to 10 A further embodiment is shown in FIGS. 5 to 10.
  • the trolley L is suspended with its hook 30 on a lifting device (not shown), a crane hook or the like.
  • a lifting device not shown
  • rollers R it guides the web 3 of the roll bar 1 on both sides of the roll bar flanges 2.
  • the mandrel 4 On the inside 31 of the roll bar 1, the mandrel 4 is fastened, in which the pivot lever 14 designed as a double lever is pivotably mounted about the axis 13.
  • the short lever arm 12 engages in a window-like recess 11 of the foot 10 of the clamping jaw 6, the friction lining of which is designated 8.
  • the end 32 of the long lever arm 15 of the pivot lever 14 engages in the space between the two pins 33, which are arranged on a housing extension 34 of a pressure housing 35.
  • This is arranged between the two flanges 2 of the roll bar 1 shown in FIG. 9. It is slidably guided in its longitudinal direction between the rollers 36 mounted on the flanges 2.
  • 6 spring bolts 38 are arranged inside the pressure housing 35, which is closed by a cover 37, on each of which a compression spring 39 is mounted under prestress.
  • the compression springs 39 are supported on the one hand on the cover 37 of the housing 35, and on the other hand via a collar 40 on the pressure piece 41 of a yoke 42, the other pressure piece 43 of which bears against the eccentric 20.
  • the bolts 38 carrying the compression springs 39 are mounted in the pressure piece 41. 5 shows the starting position.
  • a locking plate 23 is fastened by means of the bolt 50.
  • This has a catch 51 and it is arranged in the range of motion of a bolt 52 which is fastened to a shaft 54 mounted in the housing 53.
  • the shaft 54 carries a handwheel 55 at its end.
  • a tension spring 57 engages on the holder 56 of the bolt 52, the other end of which is attached to the housing 53 at 58.
  • the latch 52 is held in the opposite direction of the arrow 59 in engagement with the catch 51 of the latch plate 23.
  • the position of the lock shown in FIG. 10 corresponds to the extended position of the clamping jaw 6 according to FIGS. 6 and 7. It shows that the hand lever 22 is locked in this position.
  • the entire roll bar 1 can be moved in the trolley L.
  • the arranged between the lever arm 15 and the eccentric 20 further tension spring 60 strives to keep the eccentric 20 in the position shown in FIG. 6.
  • the tension spring 60 engages on a bracket 61 on the eccentric 20 and a further bracket 62 on the pivot lever 14.
  • the eccentric 20 can be pivoted back into the position according to FIG. 5.
  • the compression springs 39 relax until the pressure plate 41 of the yoke comes into contact with the inside of the housing wall 44.
  • the long lever arm 15 of the pivoting lever 14 is returned to the starting position according to FIG. 5 by the positive guidance between the two bolts 33 of the pressure housing 35 which the clamping jaw 6, as can be seen, is retracted.
