Definitions

the invention relates to an arrangement for turning a load, with a liftable by a lifting and lowering first support means with a first load hook and with a lifting motor driven by a hoist, via which a second support means with a second load hook is height adjustable, wherein the load a first abutment point on the first load hook and / or at a second abutment point spaced from the first abutment point is suspended on the second load hook and for turning the load via relative movements of the first load hook to the second load hook combined with a rotational movement of the first or second Suspension means hanging load around an axis of rotation, which coincides with the longitudinal extension of the first or second support means, is reversible around.
the invention relates to a working method for turning a load, in which one of a lifting device raised and lowered first suspension means with a first load hook and on a second height-adjustable suspension means with a second load hook hanging load on relative lifting and lowering movements of the first load hook to the second load hook combined with rotational movement of the load suspended on the first or second support means about an axis of rotation coincident with the longitudinal extent of the first or second support means.
any change in the starting position of a load suspended on a hoisting gear is intended can be understood, which is achievable by turning the same load in the raised state, the term "turning" is also to describe incomplete turns of the load.
suspension means the invention firmly associated with the hoist ropes and chains for holding the load, possibly including including connected to the hoisting rope or a lifting chain of a hoist load-receiving means, such as a load hook.
a hoist usually has a hoist, which allows lifting and lowering of the load and consists essentially of the lifting drive, a transmission and a braking device.
German patent DE 40 12 381 C2 describes an overhead crane with a two-rail cat used in a foundry for transporting and emptying heavy ladles.
the overhead crane is set up to turn loads.
two simultaneously or independently operated hoists are arranged on the two-rail cat of the gantry crane, each having a support cable with load hooks.
Each of the load hooks can be connected to one of the two opposite attachment points on the load.
the load hook is fixed at the top and at the rear end of the building board and the two loops at the front end.
the first loop is at the top and the second loop at the bottom.
the hoist suspended on the crane tether is lifted while the hoisting hook of the first rope is lowered by the hoist.
the building board is raised altogether and pivoted about a pivot point in the region of the loops.
the two attachment points of the loops are offset in height in the starting position and arranged in the target position on a horizontal plane on the container, the resulting difference in length of the cable strands of the second rope is compensated by a corresponding circulation of the second rope around the deflection roller.
the second rope has a fixed length and is raised only in total by the crane and together with the hoist.
the invention has for its object to provide a simple, compact and inexpensive arrangement with low weight and to find a working method for turning hanging loads, can be turned safely with the heavy cumbersome loads.
a simple, achieved compact and cost-effective construction in that the required to turn the load lifting and lowering the load is done exclusively on the hoist with the first support means and the first load hook, the lifting motor of the hoist is designed so that only the dead weights of the second support means, the second load hook and any necessary stop means are liftable, and
a load hook means any type of fastening means with which a load can be fastened to a suspension element.
the invention creates a quasi-static load reversal arrangement which reduces the function of lifting and lowering the load on only one of the suspension means, while the other suspension means is designed exclusively for holding the load. Due to this division, only the hoist for lifting a hoist motor, which is to be interpreted as before to the maximum weight of the load, while the second support means, which is designed only to hold the load, in the simplest case may be limited to a chain or a rope , their or their Load hook is struck or hung on the second attachment point of the load.
the second suspension element is provided exclusively for holding and not lifting the load, it must be designed only statically on the weight of the maximum load to be held.
the hoist motor when using a chain or cable which does not have the task of lifting the load, must therefore be designed only for the power required to adjust the height of the at least one additional load hook along with the required stop means.
the entire arrangement can be made smaller and lighter. Simply by reducing the lifting motor, which according to the invention only has to lift the low weight of the second support means, the weight of the arrangement is reduced significantly in favor of the load capacity of the entire carrier crane.
a preferred embodiment provides that the second load hook of the second support means for attaching to the load to be turned on the height of the second attachment point can be raised or lowered and the second support means can be fixed after hooking the load hook to the second attachment point of the load at this altitude is.
the hoist comprises a holding device of which the second load hook can be fixed positively or non-positively in an altitude required for the turning operation.
the holding device and the second support means are designed with respect to their static load capacity to a maximum load to be held.
the hoist is a chain hoist and the second support means is a chain.
the invention can thus rely on inexpensive, available as standard parts on the market chain hoists with proven mechanics, which are selected according to the maximum load to be manipulated.
a chain hoist is selected whose mechanism is designed for 5000 kg, the hoist motor, however, is designed much weaker, for example, less than 100 kg, because this only has to raise the weight of load hook, slings and chain.
the hoist and the hoist are arranged together on a trolley and can thus be moved in the horizontal direction.
a first suspension hook in which a first suspension hook can be lifted and lowered by a hoist with a first load hook and at a second height-adjustable suspension means with a second load hook via relative lifting and lowering movements of the first load hook to the second load hook combined with rotational movement of the load suspended on the first or second suspension means about an axis of rotation coincident with the longitudinal extent of the first or second suspension means, achieves a simple, compact and cost effective operation by virtue of the first load hook before lifting the load is connected via a centrally located at an upper side of the load provided first stop point with the load, the load is raised exclusively on the first support means of the hoist and for a first turning section, the second support means in a desired height e is set and the first support means is lowered while turning the load.
the second suspension element with the second load hook is adjusted in height via a hoist driven by a hoist motor and the hoist motor of the hoist is designed so that only the dead weight of the second suspension element, the second load hook and any necessary stop means can be lifted are.
FIG. 1 is a schematically drawn overhead crane 1 shown with an inventive arrangement for turning a load.
the overhead crane 1 is shown as a single-carrier overhead crane; Double-girder overhead traveling cranes can be used as it were.
the ends 3 are supported on both sides with trolleys 4 each on a crane runway 5, a trolley 6 with wheels 7 along the support 2, which also serves as a rail 8, movable.
the trolley 6 carries a hoist 9 for a schematically illustrated load 10 which is suspended on a load hook 11 of a first support means 12 and lowered.
the load 10 is provided with a plurality of attachment points A to C for the first support means 12 and a further to be described second support means 15.
the schematically illustrated load 10 is essentially parallelepiped-shaped and has the first attachment point a centrally on an upper side surface.
the second attachment point b is centrally provided on the right side surface.
a third attachment point c is arranged on the lower side surface and thus the first attachment point a opposite.
the three attachment points a to c are formed in the present embodiment as eyelets, so that the first load hook 11 and a second load hook 16 can be easily struck thereto. It will be understood that the load 10 to be turned may be of any shape and then the required attachment points a to c may be provided either in the form of corresponding eyelets or screw-on eyelets or other stop means such as rope loops on the load.
the hoist trolley 13 is driven and connected via a coupling rod 29 with the trolley 6.
the hoist 14 has a further second support means 15, which is designed as a chain and to which a second load hook 16 is attached.
the second load hook 16 can be stopped at a second stop point b spaced from the first attachment point a of the load 10.
the hoist 14, which will be described later in more detail, is statically designed for the maximum weight of the load 10; the hoist motor is dimensioned according to the dead weight of the second support means 15 and the second load hook 16, but not designed to lift the load 10.
the invention can be explained most simply by means of a turning process of the load 10, which in the sequence of FIGS. 2 to 9 is shown.
the hoist 14 in addition to the hoist 9 has the function of a load turning device.
FIG. 2 is the load 10, as the arrow symbolize to be raised and is suspended at the first attachment point a by means of the first support means 12 of the hoist 9 on the trolley 6.
the second attachment point b on the right side of the load 10 is not yet occupied; to recognize but is the freely suspended second support means 15 (the load hook is not shown), which is provided, but not yet attached to the attachment point b.
FIG. 3 shows the load 10 is raised, as can be seen by the schematically illustrated distance of the load 10 from the bottom 17. Meanwhile, the second suspension element 15 has been struck at the second attachment point b of the load 10. By shortening the second support means 15 of the second hoist 14, the second support means 15 is slightly tensioned, but does not raise the load 10 in this case. The second support means 15 is tracked only the lifting movement of the first support means 12. This process is indicated by the direction of the arrow coinciding with the second support means 15.
the load 10 can be seen to be lowered by lowering the first suspension element 12, but the second suspension element 15 remains fixed, so that the turning process of the load 10 is suspended by the second attachment point b on the second suspension element 15.
the fixing of the chain of the second support means 15 is symbolized by the transverse line 18.
FIG. 6 shows that in this position at the second attachment point b and the second support means 15 hanging the load 10, as the curved turning arrow shows, is rotated by 180 ° about its vertical axis.
the first support means 12 is struck on the third stop point c on the first abutment point a opposite side of the load 10. Then, the hoist 9 of the trolley 6 is operated to lift the load 10 with the first support means 12, as in FIG. 7 shown.
FIG. 8 shows that in still unchanged altitude of the second attachment point b, ie fixed second support means 15, the load 10 is further raised by the first support means 12 in the arrow direction and thereby turned further until the previous bottom of the load 10 is rotated upwards. This can be seen on the orientation bar 19 shown graphically in the load 10.
FIG. 9 is the turned load 10 after lowering the first support means 12 in the direction of arrow or lowering the hoist 9 after previous release of the second support means 15 from the second attachment point b shown.
the load 10 is opposite in one FIG. 2 180 ° turned position on the ground 17.
the second support means 15 has not been changed in height and thus has performed no lifting function.
the second support means 15 was used exclusively for holding the load 10, while all lifting operations of the load 10 were performed by the first support means 12.
the hoist 14 is shown schematically in training as a chain hoist, as it is preferably used in the inventive arrangement for driving the second support means 15 for use.
the hoist 14 consists essentially of the suspended from the hoist undercarriage 13 housing 21, in which a transmission is integrated, the second designed as a chain support means 15 with the chain memory 22 and the second load hook 16.
the second support means 15 is to that of the lifting motor 23rd driven sprocket 24 out, so that the second load hook 17 can be raised and lowered.
the lifting motor 23 is flanged to the housing 24 and passes the drive torque in the gears 25 of the transmission (see FIG. 13 ).
FIG. 11 shows a side view of FIG. 10 In order to show that the lift motor 23 can only move the second support means 15 and the load hook 16, this has been shown to be relatively small.
FIG. 12 shows the hoist 14 of the FIG. 11 in a partially sectioned view along the section line BB with a view into the housing 21 on the side facing away from the lifting motor 23 side.
a brake can be seen, which acts on the input shaft 28 of the transmission and with which the chain hoist 14 is blocked.
the brake 26 is released, the load hanging on the load hook 17 is held solely by the mechanical parts of the hoist 14; the lifting motor 23 is not loaded.
the release of the brake 26 takes place only after the weight of the load 10 has been removed from the second load hook 16 or taken over by the first support means 12, so that the driven lift motor 23 only has to move a second support means 15 and the second load hook 16.
FIG. 13 is a partial section through the housing 21 along the section line AA in FIG. 10 as seen from above.
the mutually meshing gears 25 are provided on the common extended output shaft 30 of sprocket 24 and one of the gears 25, the brake 26 is provided on the side remote from the sprocket 24 side.
a correspondingly large-sized pawl may be provided with a ratchet wheel, with which the holding forces can be taken with the load 10 attached.
the lifting motor 27 When holding the load 10, the lifting motor 27 is completely relieved of the holding forces of the load and is only after releasing or deactivating the pawl or the brake 26 active. However, this is done only in the load-free state, so that the lifting motor 23 when lifting only the self-weight forces of the second support means 15 and the second load hook 16 must accommodate.
