Definitions
- the invention relates to a lifting device with a handle section and an associated head section for lifting objects.
- metal sleeves for lifting castings or prefabricated parts made of concrete, wood, steel or other materials, for example.
- These metal sleeves have an internal thread, which is accessible from above, in order to be able to screw lifting devices into them, for example by means of screws with a corresponding thread and an annular screw head.
- the lifting devices which generally have a handle section for lifting and a head section connected to this for attachment to the part to be lifted, such finished parts can be lifted.
- the object of the present invention is to provide a lifting device which enables a simpler relocation of, for example, finished or cast parts.
- the dimensions of the parts to be lifted being almost unlimited, provided that a correspondingly dimensioned lifting device, in particular a crane, is provided.
- a correspondingly dimensioned lifting device in particular a crane
- the head of the lifting device has to be pushed through a corresponding opening of the part or into a cavity of the part and then the locking element has to be transversely positioned relative to the insertion device.
- the locking element With the locking element in the transverse position, the part to be lifted can easily be lifted by hand or by crane hook using the handle section.
- the lifting device is released in that it is pushed a little in the direction of the part to be lifted, the locking element is returned to its starting position and then the entire lifting device is lifted out of the part to be lifted again.
- the locking device By designing the locking device as a particularly elongated, pivotable element, the pivot axis of which is arranged off-center, so that in particular a long and a short leg are formed, the locking element automatically pivots when it is held vertically in its initial position for insertion into a part to be lifted or to pull out of it.
- a Bowden cable with in particular an adjustment handle which is preferably dimensioned such that it can be received entirely within an opening of a handle section and does not protrude laterally, is preferably used to actuate the locking element.
- a second opening is provided on the handle section next to a first opening in which the adjustment handle is received Opening for lifting the lifting device, in particular designed for inserting a crane hook.
- a groove in the corresponding side of the locking element makes it possible to receive a Bowden cable wire for pivoting the locking element in the relaxed position, so that the locking element can be arranged parallel to the longitudinal axis of the lifting device in the starting position.
- the formation of a groove in the locking element with a length which is chosen so that the groove is almost completely or completely covered by the head portion in any position, has the particular advantage that contamination and clogging of the groove can not or hardly take place.
- the grip section is connected to the head section in a particularly advantageous manner with a rope, in particular a steel rope, with an incorporated Bowden cable for actuating the locking element.
- a rope in particular a steel rope
- Bowden cable for actuating the locking element.
- actuating elements for example motors or, can also be used to actuate the locking element
- Hydraulic devices can be used. When using remote-controlled devices for adjusting the locking elements, the use of sensors with position feedback is useful in order to be able to reliably assess from a distance in which position the locking element is located.
- Figure 1 shows a lifting device according to a first embodiment from the front.
- Figure 2 shows the lifting device of the first embodiment from the right with a transverse locking element.
- Figure 3 shows the lifting device of the first embodiment from the left with the locking element in the basic position.
- Fig. 4 shows a second embodiment of the lifting device from the front
- Figure 5 shows a third embodiment of the lifting device and an anchor element which is cast, for example, in a concrete slab.
- Fig. 6 shows another embodiment of the lifting device in cooperation with a sleeve-shaped anchor element.
- the lifting device essentially consists of a grip section 1 and a head section 2, which in the embodiment shown are connected to one another via a connecting section 3.
- a cable in particular a steel cable 3, serves as the connecting section, although other cables or a rigid element such as a steel rod can also be used as the connecting section 3.
- the terms “above” and “below” are used on the assumption that the lifting device is usually oriented essentially vertically with its longitudinal axis from the handle section 1 to the head section 2.
- a rod-shaped one Bolt element 4 is used pivotably.
- the head section 2 has in its lower end region a U-shaped cross section from the side view, which is dimensioned such that the locking element 4 is accommodated between the two U-legs 5 without play, but still freely pivotable.
- the lower outer walls of the U-legs 5 are, as shown in Fig. 2, preferably rounded or conical, so that after the insertion of the vertical locking element 4 no beveling of the end faces of the U-legs 5 occur at the edges of an insertion hole of a casting can, but an additional insertion aid is given.
- the locking element 4 can also be tapered or rounded towards the lower end side in the basic or insertion position, as is indicated in broken lines in FIG. 3.
- the bolt 6 is guided eccentrically through the locking element 4 so that it has a short and a long leg 7 and 8 starting from the bolt 6. If the head section 2 is held in such a way that its front end points downward, the locking element 4 aligns itself vertically with its longitudinal axis due to the force of gravity, in particular when the leg 8 has a greater weight, as shown in broken lines in FIG. 3-. As a result, the head section 2 and the locking element 4 can be passed without problems like a probe into and through a bore in a finished part. An actuation by means of an adjustment mechanism, in particular a Bowden cable described below, is only required for the transverse positioning of the locking element 4.
- an adjustment mechanism in particular a Bowden cable described below
- the locking element 4 can be pivoted by approximately 90 °, so that a defined insertion or basic position with a vertically arranged locking element 4 and a lifting position with a transverse position 6
- Bolt element 4 are specified. This serves in particular for security, since when the head section 2 is being passed through an opening in an opaque prefabricated part, it cannot be seen from above in which angular position the locking element 4 is just aligned.
- the locking element 4 When the locking element 4 is transverse, its side wall 4a of the long leg 8, which is then arranged at the top, abuts against the end face of the stop 9. In the basic position, however, the side wall of the short leg 7 abuts laterally against the inner wall of the stop 9, which is why an embodiment while maintaining a short leg 7 is preferred.
- the bolt 6 also leads eccentrically through the cross section of the locking element 4, i. H. closer to the side wall 4a, which cooperates with the stop 9.
- a bore 10 or 11 leads through the handle section 1 and through the head section 2 in each case in the longitudinal direction thereof for receiving the steel cable 3.
- the bore 10 is in the handle section 1 flared at the top.
- the bore 11 in the head section 2 is flared at its lower end, ie towards the opening between the two U-legs 5.
- the handle section 1 and the head section 2 are pushed over the steel cable 3 in a first operation. Then the two ends 12 of the steel cable 3 are split open and z. B. potted with tin so that the flared portions of the bores 10 and 11 are completely filled and the steel cable 3 over the end portions in the handle portion 1 and the head portion 2 receives a firm hold. 7
- the steel cable 3 in the handle section 1 or in the head section 2 can also be pressed over the steel cable.
- its upper end is conical towards the steel cable 3.
- an annular cone 31 the lower diameter of which is equal to that of the head section 2 and the upper diameter of which is almost the same as that of the steel cable 3, is pressed onto the steel cable 3 adjacent to the head section 2 above the head section 2.
- the transition from the grip section 1 to the steel cable 3 can also be conical, for example by pressing on a cone 30.
- the adjustment mechanism for adjusting the locking element 4 preferably consists of a Bowden cable 20 which passes centrally through the steel cable 3.
- the Bowden cable 20 can be incorporated directly in the manufacture of the steel cable 3 or later exchanged for the usual hemp core of a steel cable 3.
- a longitudinal groove 16 is incorporated, which serves in the basic position of the locking element 4 for receiving the Bowden wire 21.
- a Bowden cable bearing pin 13 runs through the groove 16, the longitudinal axis of which runs parallel to and at a distance from the pin 6. The free lower end of the Bowden cable wire 21 is articulated on the Bowden cable bearing pin 13.
- the adjusting handle 14 In the basic position with a vertical locking element 4, the adjusting handle 14, as shown in FIG. 3, is pulled away from the cable end 12 in the handle section 1.
- the upper section of the Bowden wire 21 can be marked accordingly in color.
- the lifting device After the cast part has been set down, the lifting device only needs to be lowered a little further, so that the side wall 4a of the short leg 7 no longer lies against the underside of the cast part and the locking element 4 can automatically pivot back into the basic position with the aid of gravity.
- An actuation of the adjustment handle 14 for pivoting the locking element 4 back into the basic position is generally only required in cases where, for. B. an offset casting was so set that the head portion 2 is not arranged vertically with its longitudinal axis after being set down.
- the adjusting handle 14 is dimensioned such that it is received entirely within an opening 15 of the handle section 1 and does not protrude laterally therefrom. This can prevent unintentional actuation of the adjustment handle 14 when handling the lifting device.
- the opening 15 in the handle section 1 can preferably also be suitably shaped as a handle for gripping or inserting a crane hook.
- a second exemplary embodiment of a lifting device is shown in FIG. 4. For the sake of simplicity, only the elements that differ from the corresponding components of the first exemplary embodiment are described.
- the groove 16 ' which is formed in the locking element 4 on its side wall 4a, now leads through the entire short leg 7 and over the bolt 6 into the long leg 8.
- the Bowden cable bearing pin 13 ' is shifted into the long leg 8 of the locking element 4. If the groove 16 'is cut so deep into the locking element 4 that the bolt 6 passes through it, the Bowden cable wire 21 rests on the bolt 6 in the basic position.
- the Bowden cable bearing bolt 13 ' is therefore used to fix the end of the Bowden cable wire 21 less deeply in the groove 16' than the bolt 6, so that the Bowden cable wire 21 is not or only slightly in contact with the bolt 6 in the basic position.
- the adjusting handle 14 is advantageously pulled up for the transverse positioning or pulling up of the locking element 4, which simplifies handling and enables intuitive operation of the adjusting mechanism.
- the leverage and the actuation or adjustment path of the adjustment mechanism are again determined by the distance between the pin 6 and the Bowden cable bearing pin 13 '.
- the handle section 1 has a further opening 17 for lifting the lifting device.
- a push rod or push rod can also be used instead of a Bowden cable.
- remote-controlled adjustment mechanisms using hydraulic or pneumatic devices or electrical adjustment mechanisms, such as electromagnets or motors.
- the installation of sensors or switching mechanisms with position feedback is useful in order to be able to reliably indicate the position of the locking element 4 to the person who operates the lifting device from a distance.
- a fully automated or partially automatic adjustment of the locking element 4 can be supported, for example, in the basic position by the use of spring elements.
- the third exemplary embodiment shown in FIG. 5 shows that not only a single locking element can be used, but also the use of a plurality of locking elements 22 and 23 is possible. All possible types of locking elements, such as plate-shaped or triangular-plate-shaped locking elements, can be used, provided that they can be adjusted or extended laterally to the longitudinal axis of the head section 2, for example, can be spread out like an umbrella.
- anchor 25 for lifting devices of this type, which can be built into or cast into them during the manufacture of finished or cast parts, such anchors 25 being of independent inventive importance.
- such an anchor 25 consists of a tubular shaft 26 which has a through opening from the top, for example of a molded or cast part 40, to the underside thereof.
- the material is particularly suitable 1 1
- Plastic but other materials, such as. B .. metal or even cardboard, can be used, since this is enclosed by the load-bearing Ar ier- or molding material.
- the shaft 26 preferably has collars 27 and 28 at its two front ends.
- the upper collar 27 can be funnel-shaped in order to facilitate the insertion of the head section 2 of a lifting device.
- active and / or passive sensors or transmitters can also be incorporated into the collars 27 and 28, which can cooperate in particular with corresponding receivers or transmitters on the head section 2 of a lifting device.
- the lower collar 28 preferably forms an abutment wall, which preferably extends radially so far away from the shaft 26 that it enables the side wall 31 - 33 '' 'of the transverse locking element 22 or 23 to rest completely and evenly. This provides a secure and even hold for the locking element 22 or 23 even in the case of uneven or pressure-sensitive contact surfaces of the part to be lifted.
- the anchor 25 is cast into a prefabricated concrete part 40, with the reinforcing irons in the corner region between the shaft 26 and the collar 28 (not shown) to fix the anchor 25. So that no concrete can flow into the anchor 25 during manufacture from below, it has an anchor chamber 29 which starts from the U wall of the collar
- the anchor chamber 29 can e.g. B. be a substantially cylindrical body, but is used for
- a substantially hemispherical anchor chamber saves space
- the surface 31 serves as a narrow support surface. If the locking element 22 can be pivoted out a little further, the somewhat wider contact surface 32 can be used to reach under the part 40 to be lifted. If there is the possibility of pivoting the locking element 22 out completely, a generally relatively large bearing surface 33 is provided, which is subdivided into sections 33 ', 33 "and 33'".
- anchor element 25 shown in FIG. 6 the insertion opening of which is dimensioned and / or has such a cross section that only the insertion of a correspondingly dimensioned or shaped head piece 2 of a precisely fitting lifting device is possible.
- the balls 4 'provided here as locking elements 4 engage for locking in a U-shaped groove 28' of the anchor element 25.
