Definitions
- the invention relates to a receiving device for provided with a receiving eye Loads according to claim 1.
- DE 32 13 693 C1 discloses a load suspension device with a load hook known, which is pivotable about a horizontal axis in a mounting device.
- the axis with the load hook and an associated housing is in the Attachment device guided vertically.
- One on the mounting device provided control pin ensures pivoting of the load hook and that Triggering a lock for locking the attachment device with the housing every second touchdown.
- the load hook is pivoted when Place the placement device, which ensures centering, on the one to be lifted Load, whereby when the load hook is swung out, it loosens into a The receiving eye can be swiveled in.
- a disadvantage of this load suspension device is that it does so in the event of operating errors can come that the receiving eye is gripped with the tip of the load hook, which in turn can cause the load to crash. Furthermore, the known Load suspension device, the attachment device on one side of the hook arranged. This requires the use of counterweights, which is a unnecessary load and associated increased wear and tear Represents load suspension device. Disassembly is also very complex.
- the object of the invention is to provide a receiving device for with a Load eyelet to create loads where there is no lifting the load can come from the peak load as a result of an operating error. Will continue a symmetrical structure of the placement device is sought with respect to the hook.
- the invention provides that parts of the centering unit after pivoting the Close the hook of the hook. This prevents a Gripping the load through the hook tip as a result of incorrect operation occurs.
- the load hook thus forms, together with the parts of the centering unit close the hook mouth, a closed eyelet. This solution makes it possible further to achieve a weight distribution within the cradle that due to a symmetrical structure that is now possible, no additional ones Balance weights needed.
- the hook jaw can be closed with little effort by that the hook tip in the load suspension position of the directly opposite arranged centering unit is covered.
- the existing centering unit has both a centering function and a covering function in the invention.
- a simple closing of the hook jaw is made possible by the fact that the Hook tip in the load-bearing position in a form-fitting manner in a recess of the Centering unit engages.
- the recess can be made without additional Realize means that the recess in a sliding element Centering unit is formed.
- the displacement element is expediently a component in the receiving device, which is mounted in this vertically displaceable and on carries a centering frame at its lower end.
- an articulated lever which has one end on Sliding element and with the other end on the shaft of the load hook such is articulated that a vertical displacement of the displacement element with a pivoting of the load hook is connected.
- Fig. 1 shows a receiving device 1 in cross section, in which one horizontal axis 2 pivotable load hook 3 is mounted in a housing 4.
- the Recording device 1 is provided with a centering device 5, the one automatic centering when placed on a specially designed receiving eye 6 ensures.
- the centering device 5 also ensures that the load hook 3rd each from a lockable position to another lockable position is pivoted.
- the one locked position is the swung out position Ready position of the load hook 3 next to the receiving eye 6, as in FIG. 1 shown, and the other position that shown in Fig. 2, in which the load hook 3 in the load suspension position.
- the initiation of the swivel movement from the one in the other lockable position is done by putting on with the centering unit 5 interacting with the load hook 3.
- the pivoting movement of the load hook 3 takes place in one vertical plane into the eyelet 6.
- Fig. 2 also shows that parts of the centering unit 5 after pivoting the Load hook 3 close the hook mouth 7 by the hook tip 8 in the Load suspension position (Fig. 2) from the directly opposite Centering unit 5 is covered.
- Figures 1 and 2 further show that the centering unit 5 from a frame 9th consists of a diagonally arranged connecting element 10 with a vertical aligned and displaceable displacement element 11 is connected.
- the Sliding element 11 is vertically slidably mounted in the receiving device 1, namely roller-guided, so that the centering frame 9 with respect to the housing 4 only perpendicular to or away from the housing 4.
- the roller guide ensures increased ease of movement; the locked state can also be changed by hand in this way.
- a vertical guide in the housing Formed a guide channel 12 in which the sliding element 11 is vertical is movable.
- the interaction of the load hook 3 and the centering unit 5 when mounting takes place via an articulated lever 13 which on the load hook 3 in the area of Pivot bearing and is rotatably mounted on the displacement element 11 and a uncontrolled swinging of the load hook 3 prevented.
- the arrangement of the Bearing points is chosen so that the load hook 3 when the Sliding element 11 upward swiveling of the load hook 3 takes place at Downward displacement swivels the load hook 3 into the receiving eye.
- the articulated lever 13 is supported by a bearing bush which can be dismantled the cradle is simply moved.
- the articulated lever 13 is mounted on the load hook 3 on a bolt 14 which is in a Locking rotating link 15 extends.
- the locking rotating link 15 is as Rotating backdrop formed, d. H. the bolt 14 slides in an endless slot on one closed curve without changing its direction of movement.
- the Locking rotating link 15 is further designed so that the load hook 3 at two Positions of the bolt 14 in the course of its path within the Locking rotating link 15 is locked automatically. Each time again Attaching the frame 9, the lock is released and the load hook 3 at repeated placement of the frame 9 pivoted into the other position where it is locked again.
- the cover of the Hook tip 8 in that it positively in a recess 16 of the Centering unit 5 engages.
- the recess 16 is thereby formed that the displacement element 11 and the connecting element 10 angled are arranged to each other, d. H. the connecting element 10 is to the outside angled.
- the recess 16 arranged in the kink area is designed such that the load hook tip 8 on a horizontal surface of the displacement element 11 Plant come.
- the hook tip 8 is due to the The weight of the centering unit 5 is acted upon by force on the displacement element 11.
- the receiving eye 6 has an outer contour on, which is adapted to the centering unit 5.
- the Receiving device 1 over the frame 9 automatically opposite the receiving eye 6.
- the housing 2 slides through its own weight in a lower end position. Only then is the load hook 3 by means of the Articulated lever 13 swung out.
- the bolt 14 slides within the backdrop 15 in a locking position.
- the load hook swings in slightly and is only in locked this position.
- the load hook 3 is initially pivoted slightly outwards, which releases the lock.
- the wedge-shaped opening 17, which consists of the load hook and the connecting element is formed, is chosen so that it is closed, even in the case of the load hook 3 Load suspension position, it is possible to capture the lifting eye 6.
- the Opening 17 also makes it possible to use conventional recording devices Operate lifting gear (chain, rope, etc.).
