Abstract

The lifting mast (1) can rotate around a counterweight (9) on the basis of the equilibrium situation between a load and a variable counterweight. The lifting mast and counterweight are not mounted on a single platform. The lifting device has at least one lifting mast, a rear mast (2) and at least one counterweight.

Description

Title: Flexible and multi-purpose detachable, movable device (s) for various lifting and lifting activities.

The invention relates to modular or non-modular systems of relatively quick and easy to assemble and dismantle device (s) for hoisting, lifting and moving very heavy and bulky loads at locations that are difficult or impossible to reach.

The present invention is based on a movable and removable hoisting device, which consists of at least one hoisting mast and at least one counterweight (also usually a back mast), the mast (s) in concept and in dimensions, both in cross-section and in length, need to implement.

15 Based on the balance between load and variable counterweight, very heavy and bulky loads up to large lifting heights can be lifted.

In the present lifting device, the foundation on which a building or heavy installation is placed or even the building or installation itself can serve as a counterweight. Another heavy installation can also serve as a counterweight, so that one installation is used to hoist and / or move the other. Loose (possibly liquid) ballast, preferably in container form, can also serve as a counterweight.

The present hoisting devices consist broadly of one or more masts, mast base constructions, hoisting and displacement units, foundations and the like, whether or not assembled and assembled on site, as they are inter alia.

30 are described in patent applications US6,259,564B1; US4,016,954 A / US3,921,611A; US 3,921,611; WO 95/31655, PCT / NL00099 and NL 1005059, wherein it is explicitly stated that mobile and movable hoisting installations, 1020816 2 portico constructions and rigged lifting masts can be equipped with. supporting frame (s) belonging to the invention and so-called superlift supplement constructions.

The displacement units under the support frame can, inter alia, consist of multiple wheel sets and / or sled shoe constructions, such that they are adjustably connected to the support frame in the horizontal plane.

The displacement units under the counterweight (if used) can also consist of, among other things, multiple wheel sets and / or sled shoe constructions, which can also move in a straight, circular or combination movement thereof, whether or not in combination with the displacement units below it. 15 support frame of the main and possibly back mast.

The supporting frame will generally be able to move on a suitable track for the stationary counterweight, possibly also on another suitable track.

In short: The present invention focuses, inter alia, on rotating the lifting device about the counterweight or ballast, with the supporting frame moving. Turning is also understood to mean that the counterweight or counterweight can move over a smaller radius than the support frame.

In the current state of the art, the displacement units, for example consisting of multiple wheel sets and / or sled shoe constructions, are designed as a duo set, pushed forward at the rear of the sled shoes, or withdrawn by means of centrally arranged hydraulic single cylinders, 30 which are deposited on the circle segment foundations composed in parts, or gutters or tracks called in the professional jargon.

1020816 1 3

After each crossing of the enormous, heavily loaded sled shoe construction from one circle segment foundation to the other circle segment foundation, especially when retracting, the forces are absorbed centrally by a generally not or sufficiently loaded circle segment foundation, which as a result cannot properly fulfill its retraction function, because no or insufficient weight load on the sled shoes at rest.

By now replacing the centrally placed cylinders by two cylinders, one cylinder of which is arranged on the inside and the other cylinder on the outside of the sledge shoe and both engage on the loaded circle segment, the so-called "rising" of the prevent sales segment.

The circle segment foundation is in principle suitable for one selected continuous diameter.

For other diameters, it is possible to use additional filler couplings, which may or may not result in curvy transitions between the basic foundation segments.

Due to the steering possibility of the pulling and pressing mechanism, consisting of the aforementioned cylinders mounted on either side, it is easy to go through every curvy transition.

As a result, for any other turning circle than the chosen turning circle, a foundation or guide structure that cannot be made again is no longer necessary.

In short: The present invention focuses, inter alia, on the placement of two cylinders (of the pulling and pushing technology) where the foundation of the lifting device is loaded by a sled shoe.

102 0816 "4

On the basis of the balance situation between load and counterweight, whereby through the main A-frame (front mast) and the ballast mast (rear mast), both coupled at the top by a longitudinally changeable strut, very heavy and bulky loads can become very large lifting heights are lifted.

The load can be accurately positioned on the basis of the so-called topping and topping up by means of the change in length of the aforementioned strut.

Usually so-called f, beach jacks and / or winches are used for controlled checking of topping and topping up by means of steel cables and conical clamping bodies.

In short: The present invention is directed, inter alia, at topping and topping up with rigid rods or tubes and the like, which are designed so that they can be locked or tucked up by means of hydraulic cylinders.

To hoist and possibly move very heavy loads, the most essential parts of the present lifting device are: a triangular foot construction, whereby the front mast can come to stand almost vertically.

- Pull-push bars.

At different heights, side-tensioning equipment for the main boom.

The rear mast combined with the ballast foundation plate, to which is hingedly attached, a tubular structure around which the hoisting device can rotate.

The main mast (s), which may possibly be double or multiple, can be connected by coupling the container-shaped mast parts not only in the longitudinal direction, but also laterally and possibly also below each other.

1020816 5

Due to advancing practical requirements, with regard to flexibility and usability of such a large lifting device (s), there has been a great need to use both the same lifting device or parts of the lifting device 5 for both light and extremely heavy lifting operations based on various, even based on completely different lifting methods.

In short: The present invention focuses, inter alia, on the present construction, in which the "large" crane / lifting device can be split into two or even possibly several parts for lighter lifting and moving operations.

As a result, for the generally less frequently occurring large lifting orders, anywhere in the world, it can be carried out by bringing the lifting device parts together there and assembling them into one "large" crane / lifting device. It is conceivable that the preparatory work for the "large" lift is done by the smaller embodiment.

The invention relates in particular to modular systems of relatively quick and easy to assemble and disassemble devices for hoisting, lifting and moving very heavy and bulky loads at locations that may or may not be difficult to reach.

For this, as stated earlier, use is made of dimensions of current land and / or sea container sizes. These parts, carried out in container sizes, are usually filled with separate parts of the lifting device during transport from and to location.

In the practice of transporting containers, not only the dimensions, such as for example 20 or 40 x 6 x 6.6 feet of the container, also apply, but also the maximum loading weight including the container.

1020816 6

Usually these are maximized around 24 or 30 tons weight.

Other standard weights and standard weights that have changed over time, or dimensions are also included.

The detachable twist-lock covers (covers with standard coupling possibility connection for mast parts container transport by road, by air or by water) are made hollow, so that ballast weights and the like can be included as a filling without extra freight costs.

In short: The present invention is directed, inter alia, to open or "hollow" screw-on spaces, which can be filled until the maximum permissible weight of the entire container is reached. As a result, the degree of filling or the degree of loading of the containers is optimally utilized.

On the basis of, in particular, modular systems of devices which can be assembled and dismantled relatively quickly and easily for hoisting, lifting and displacing very heavy and bulky loads at locations which may or may not be difficult to reach, it must be possible simply and quickly to move the counterweight.

For this, the counterweight has been broken down, namely:

In A: a foundation plate, possibly composed of several parts, but hoisting in its entirety by means of a sufficiently heavy tube construction and pressing downwards.

The heavy tube construction is pivotable at the foot at the height of the foundation plate and pivotable at the height of the top of the rear mast, so that a slight angle with respect to the foundation plate is possible.

Through the heavy draw / pressure tube construction, the rear mast (s) can rise and fall, whereby possibly more favorable mast pull-up positions can be achieved.

1020816 7

In B: an additional "loose ballast" to be added and / or removed, possibly filled containers.

Because the additional loose ballast can be quickly removed, the lifting device as a whole can be moved completely with a minimum of ballast weight (namely the foundation plate).

In short: The present invention is directed inter alia at a foundation plate and additionally to be added and / or to be removed "loose ballast", optionally filled containers.

The base plate is rigid and yet hinged by means of a tubular construction coupled on the one hand to the rear mast (s), so that pressure and tensile forces can be exerted on the base plate and on the other possibly also pivotable. coupled to the ends of the rear mast (s), so that the rear mast (s) can rise and fall and even turn, whereby favorable mast pull-up positions and / or hoisting positions can possibly be achieved.

In short: The present invention is directed, inter alia, at a pressure / draw tube construction, so that the rear mast (s) can rise and fall and even turn, whereby favorable mast pull-up positions and / or hoisting positions can be achieved.

Various additional versions with pull, push and cross bars and various superlift versions are possible.

25 Special entries are: A) The superlift with main stand tension, whether or not combined with the superlift counterweight, again with superlift counterweight platform with central tensioning.

The associated variable superlift ballast is floating and free of the ground during 30 lifting and hoisting operations.

B) The superlift with rear mast tensioning with or without adjustable suspension cable.

1020816 8

The associated variable superlift ballast is floating and free from the ground during lifting operations.

Details, applications and methods of some hoisting and lifting device (s) belonging to the present invention with the intended counterweight will be described in a descriptive manner with reference to Figs. I up to and including X. It should be explicitly stated that embodiments other than those shown under Fig. 1 to Fig. X, based on the principles of the invention, belong to the present invention.

Fig. VIII shows a superlift version with rear mast tensioning in side view and in front view.

FIG. 6 shows, in oblique view, a lifting device consisting of a single mast with a triangular base and 5 tensioning members.

Fig. X shows - in side view - the same lifting device from Fig.IX also consisting of a single mast with a triangular base and tensioning devices.

Fig. I shows a front, side and top view of a lifting device according to the present hoisting device.

The double-mounted mast 1 (1a and 1b) and the double-ballasted mast 2 (2a and 2b) form the so-called inverted A-frame, which is supported as an example 15 by the displaceable, multiple-displaced displacement units 3 (3a and 3b) and 4 (4a and 4b).

The hoisting mast 1 and the ballast mast 2 are hingedly connected in 5 to each other and to the displacement units 3 and 4.

The load 6 in this example is supported by a platform trolley 5 at an angle above the ground floor 6.

The counterweight 9 stands on a platform 10, possibly composed of several parts, while the whole is hinged to the rear mast 2 by means of a sufficiently heavy construction 11 in 12.

The ballast 9 is arranged centrally around the pivoting tube construction 13.

The total counterweight therefore consists of a platform 10 and 30 and an additional ballast 9 to be added and / or removed, being possibly filled containers.

10208 16 10

Because the additional "loose ballast" can be quickly removed, the lifting device can be in. completely with minimal ballast weight (namely the base plate).

The robustly constructed tubular construction 13 is pivotable on the platform 10 and pivotable at the top 14 of the rear mast (s) 2, so that a slight angle with respect to the foundation plate is possible, while still pushing and pulling forces on the platform 10 can be exercised. The tops 14 of the ballast masts 2 (2a and 2b respectively) are vertically displaceable in height around the pivoting tube construction 13 and as such rise and fall, whereby possibly more favorable mast pull-up positions and / or hoisting positions can be achieved.

The distance-changeable connection between the double-designed hoisting mast top 15 and the top 10 is formed by a series of hinged, tensile-loaded top bars 16, which can be overtaken or tightly locked near the top 14 by cylinders not further specified.

The top rods 16 are supported near the top 14 by the top rod guide 20, which also cooperates in reducing the buckling tendency from the main boom 1.

On the basis of the equilibrium situation between load 6 and variable counterweight 9 (including the "fixed" weight of the platform 10) very heavy and bulky loads up to even large lifting heights can be lifted.

The load 6 can pivot around the pivoting tube construction 11, wherein the displacement units 3 (3a and 3b) and 4 (4a and 4b) are forced to describe a circular movement around the pivoting tube construction 13.

10? Oft16 11

Naturally, other movements than egg movements are possible.

Even combinations of other tracks, such as lines, elliptical or transition tracks, and combinations of arvan 5 are possible.

Most parts of the lifting device are modular, removable and transportable in dimensions corresponding to container dimensions, so that the lifting device can be set up in hard-to-reach places around the world.

Fig. I shows somewhat schematically a double design lifting device, but the present invention is based on a movable or dismountable lifting device, which consists of at least one lifting mast, such as la or lb and at least one rear mast, such as 2a or 2b and one counterweight, such as 9a, 9b, 9c or 9d.

As counterweight 9, a foundation on which a building or heavy installation is placed can also serve as a counterweight in the present lifting device.

Another heavy installation can also serve as counterweight 9, so that one installation is used to hoist and / or move the other.

Furthermore, in Fig. I, the boom stop 16a and 16b for limiting the angle 19 between the hoisting mast 1 and the rear mast 2 is shown.

The load 6 is not shown in the plan view.

Fig. II shows a front and side view of the carrying and displacement units, consisting of a four-fold sled shoe construction 21a, 21b, 21c and 21d, all of which are connected to crane yoke 22, which in the hinge point 23 is coupled to, by only one line 24 indicated 1 20816 12, hoisting mast 24 and back mast 25 indicated by only one line 25.

For the sake of clarity, only the components essential to the present invention will be explained, it being stated that in principle any embodiment is possible.

The quadruple sled shoe constructions 21a, 21b, 21c and 21d all rest on sled shoe soles 25 (25a, 25b, 25c and 25d), which are all slidably arranged in the troughs 26 (26a and 26b). The troughs are mounted on the circle segment-shaped foundation 46.

The displacement or displacement of the quadruple shoe shoe structures 21a, 21b, 21c and 21d takes place • by means of four (in which eight cylinders are not excluded) hydraulic cylinders 29 (29a, 29b, 29c and 29d respectively), all at the location of the shoe shoes 21b and 21d)

The hydraulic cylinders 29 (29a, 29b, 29c and 29d) are coupled to the bottom sides 30 with substantially the center 31 of the gutters 26 (26a and 26b) and to the cylinder head sides 32 coupled to the front sides 33 of the sled shoe constructions 21d and 21b ; possible, if also additionally equipped with another four cylinders 34, also on the front sides 35 of the sled shoe constructions 21a and 21c. By means of said cylinders 29 and 34, the sled shoe constructions 21 can be moved, pushed or pulled, in the troughs 26 (26a and 26b), the weight of the sled shoes always resting on the troughs 26; also at or after sled shoe transition from one foundation segment to the other.

Programmed feeding of the hydraulic push / pull cylinders makes it easy to move smoothly through winding transitions between the basic foundation segments by steering the shoes.

Linear movements can also be traversed.

As a result, for every other turning circle other than standard, a new foundation or guiding structure that is not to be made is no longer necessary and it is possible to suffice with smoothly running or straight transition segments.

FIG. III shows an embodiment of an up and down rod 35, as an example consisting of a fork shape 10 or a double plate attachment, which can be used instead of bundles of cables which are used for "controlled jacks" and / or winches for, among other things, the controlled top and bottom of various masts and loads.

'Various versions of the coupling options and application possibilities are available.

Some will be explained in Fig. III to clarify the operation.

The top rod 35 possibly consists of an eye / fork construction 36, whereby a series of top rods can be hinged and releasably coupled and secured.

Any hinged and detachable construction, such as in rod form, or in tubular or tubular form, is possible.

The top link 39 may consist of flat hinge plates 40 and 41 provided with bolt and / or pin connections 42 and 43, so that a series of top link can be hinged and releasably coupled and secured.

The tensile shapes are essential, as shown in Fig. III in the form of the conical holes 44 Combined with the clamping shape of the plugs 45. According to both embodiments of the holes 44 and the 1020816 14 plugs 45, the clamping shapes are schematic. and pulling device shapes 46 and 45.

The clamping and pulling device forms 46 and 45 can inter alia hydraulically clamp around the top link 35 and pull the top link 35 coordinately or relentlessly move.

In this way an alternative is created for cable bundles, or beach jacks and / or winch constructions.

Other clamp body shapes are also possible'o.a. as shown with the combination of the round-shaped plugs 45 and the hollow clamping and pulling device shapes 46 and 45. Of course, the distances of the plugs 45, or the cavities 46, correspond to the take-over distance of the hydraulic pulling devices not further specified.

The split pins 49 and 50 symbolize the safeguard against loosening.

FIG. IV shows for lighter lifting and moving operations a mounted part of the "large" crane / lifting device described in FIG.

Fig. IV schematically shows a triangle support 51, 52, 53 and 54 at the location of the sled shoe construction 55, wherein the front mast 56 and the rear mast 55 come to stand completely in a vertical plane.

Furthermore, in Fig. IV the pivoting point 58 is shown, as well as possible displacement paths 59 to 62 of towing foot construction 55 and load 63 at a fixed location of the ballast 64

The entire installation can also be moved linearly according to lanes 59, 60 and / or 65.

Fig. V shows a transported crane part 66, which is designed as a container with open / "hollow" screwable twistlock covers 67 and 68, which can be filled, so that the

The degree of filling, or the degree of loading of the container, which incidentally also contain twistlocks, can be optimally utilized.

The detachable twistlock covers (covers with standard coupling possibility connection for mast parts container transport by road, by air or over water) are made hollow, so that ballast weights and the like can be included as a filling without additional freight costs.

It is of course possible for the twistlock covers, such as 67 and 68, to be bundled together in multiples and filled as such with tap parts and / or foundation plates and the like.

Instead of the twist-lock covers, the twist-locks can be arranged directly on the containers in combination with the connections of the containers as mast part.

Furthermore, a smaller tap part 69 is visible in Fig. V for clarification.

In this example, the tap part 69 fits amply into the container.

Fig. VI shows the hoisting device of Fig. 1 provided with cross-rods 70, transverse pressure / pulling rods 71 and 72 and a winch 75 placed on the main mast foot 73 or the back mast foot 74, placed in the heart such that no momentary forces arise.

The winch 75 provides a kink-reducing tension on the main boom 76.

By means of the cable 77/78, which is variable in length and set to variably adjustable tension, the double-mounted lifting mast 76 (76a and 76b) can be relieved of kink.

1020816 16

The winch 75 and the winch cable 77/78 could also be replaced by only a rod "78" or a hydraulic cylinder "" 78 "", which could be placed between the main case or main strut 79 and hoisting mast 76.

The possible buckling tendency of the mast 76 can be reduced with the winch 75, dosed and compensated for.

The length-adjustable main pouch 85 is connected to the superlift pouch 84 at the location of the plyle binding 86. It is essential that the superlift platform is free from the ground floor 87 during hoisting movements. For the sake of clarity, the beach jack cable ends 88 of 20 are hoisting cables 89 made visible.

Other superlift configurations are also conceivable.

Fig. VIII shows a superlift version with rear mast tension in side view and in front view.

The present hoisting devices are hereby extended with a superlift ballast weight 90, which also comprises, for example, a superlift platform 91, a loose ballast 126, superlift masts 93 and 94, length-adjustable super lift suspension cable 95 and the superlift pouch (s) 96.

The rear mast 97 is connected at the location of the rear mast top 98 and the mast foot 99 to the super lift version with rear mast tension.
