Description

The present invention relates to a device for dislocation of anchors, consisting of a crane and a crane-mounted vibrator, which is provided with a driver and a transport device for anchoring and a support for anchoring.

Such a device is well known in the art. For anchoring, consisting of an anchor rod and a folding anchor, the anchor is driven by entrainment of the anchor rod or the like by means of a driving rod in the ground. When the desired position has been reached, by applying tension to the anchor rod, the actual anchor located in the ground is folded down, creating a resistance.

The introduction is carried out according to the prior art by means of a conventional crane, on which a mast is suspended, which serves to guide and load the drive rod. For this purpose, the mast contains a vibrating block.

It is important that such anchors are placed accurately. In particular, the end position of the armature is important for the load to be attached later thereto.

In the presence of other constructions, such as sheet pile walls, existing foundations and bridges and the like, it is necessary to bring the mast in the correct position using numerous tricks. This is often difficult to achieve and it is necessary to use all kinds of auxiliary measures, such as ships, temporary girders and the like, resulting in increased anchoring costs.

To US 2005/0247461 A1 is known by a flat link rod with a simple arm of a crane connected mast. Along this mast a vibrator can be moved back and forth.

To WO 2008/052353 is known a crane with articulated arm, at the free end of a mast for a piling device is attached.

The purpose of the present invention is to provide a device for displacing anchorages with which the mast, to which the jogging block is attached and with which the driving rod is placed, is easily and quickly brought into the correct position, whereby it is also possible to to realize different positions within a large area.

This purpose is fulfilled by the device described above in that it is a crane with a two-part articulated arm, wherein the driver articulated at the end of this arm and the position of the driver relative to the arm with actuators is adjustable, wherein the hinge attachment executed is that a movement in two different levels is possible.

According to the present invention, a crane with a single crane arm is no longer used, which is adjustable by means of ropes in height. As it turns out, this means that no clearly defined positioning of the mast is possible. However, with the help of the articulated arm construction now presented, such accurate positioning of the mast is possible. It is also proposed to provide not only a rotational movement about an axis parallel to the hinge axis of the two arm elements of the articulated arm, but also a rotational movement in a further plane, which is preferably perpendicular thereto. This makes it possible to bring the mast controlled in any desired inclination to the crane. This allows working on relatively high sheet piling away, with the mast on one side of the sheet pile wall and the crane on the other side. In addition, by placing the crane near foundations such as bridges and the like, it is possible to attach anchors at an oblique angle such that the anchor ultimately extends under such a foundation.

The hinged attachment may include any conceivable construction. According to a first variant of the present invention, hinge pins are used and the joint movement can be carried out by means of a lifting device, which is designed as an actuator. According to a further embodiment, (each) joint comprises a turntable, which can be designed with the rotation of the turntable with a lifting device or with a gear or a worm. Such a screw then serves as an actuator.

The construction of the mast in combination with the jogging block can be carried out in any manner conceivable in the prior art. It is particularly advantageous if the mast and the Rüttelblock a U-shaped receptacle, so that the drive rod can be introduced in a simple manner together with the anchor rod. With the present invention, it is possible to introduce anchor rods of relatively large lengths of several tens of meters without intermediate couplings in a single step by a corresponding design of the mast. By the above-described U-shaped design of the mast / Rüttelblocks drive rod and anchor rod can be easily positioned.

The Rüttelblock comprises according to a further advantageous embodiment as such known eccentric. In the prior art, these are lubricated with spray lubrication. Due to the great mobility of the mast and the Rüttelblocks, however, it is desirable to improve this lubrication and according to a particular embodiment of the invention, this is done by attaching an oil pump / an oil reservoir / an oil line system, whereby forced lubrication of the eccentric can be done.

The crane used is preferably a crane that operates with a hydraulic system, which among other things, the position of the arm elements of the articulated arm can be determined with each other and the positioning of the mast against the end of the arm.

Preferably, the jolting block consists of two or more opposing gears, which provide for the drive movement of the driving rod. The drive rod is preferably designed as a hollow tube, on the outside of which pins are attached. These pins serve as teeth for the gears of the Rüttelblocks.

Depending on which drive is selected for the gears, they can either (self-) inhibit in such a way that they can absorb the pressure force exerted on the driver, or there may be special braking devices or it may be Combination of both can be used. Such special braking devices may be, for example, hydraulically actuated wedges.

According to a further embodiment of the present invention, the driver is "self-supporting" executed. As a result, it is no longer necessary to use a mast with guide. This self-supporting design can be achieved in that the driver is designed as a hollow profile, for example as a rectangular profile.

According to a further embodiment of the invention, the mast is provided at the free end with a winch. This makes it possible, after the correct positioning of the anchorage to exert a tensile force on them. With this tensile force can be checked whether the anchorage meets the requirements. In addition, this winch can be used to fold the anchor. This happens at a relatively high speed, the efficiency of folding and anchoring is increased in the corresponding bottom part.

If the winch is at the same time provided with measuring devices with which it can be determined whether the anchorage meets the requirements, immediately corrective measures can be taken if necessary. These measures may consist in removing the anchoring set and immediately placing another anchorage in a different position in which the desired load bearing capacity can be achieved. This other location can affect both depth and orientation. This is in contrast to the prior art, in which the anchors are charged separately only after attaching all anchors and in a proper anchoring the device described above must be returned to the site where the anchorage did not meet the requirements.

The invention will be illustrated below with reference to an embodiment shown in the drawing. Showing:

7 a detailed view of in 6 pictured device.

In 1 is under 1 the device according to the present invention imaged. This consists of a crane known as such 2 , which with one on a lower frame 4 mounted cab 3 is provided. This cab 3 can stand opposite the underframe 4 , as well as the arm 5 rotate. poor 5 is an articulated arm and consists of the arm elements 5 and 6 , poor 5 can be due to joint 18 (first joint axis) opposite the cab 3 rotate. The arm elements 6 and 7 can have a parallel axis of articulation 13 move among each other. The movement of the arm relative to the cab is done by means of an actuator 29 while the arm elements 6 and 7 with the help of a lifting device 28 can move with each other.

At the end of arm element 6 is articulated way mast 9 attached. This attachment is as a whole with 8th designated. Details of this attachment also go out 4 out. arm member 6 is about joint 11 (which is parallel to the first hinge axis) with the attachment 8th connected. attachment 8th can with the help of a (hydraulic) lifting device 12 around this hinge axis 11 Turn (second hinge axis).

A rotational movement in a direction perpendicular thereto is also possible. This rotational movement takes place about a hinge axis 14 (third joint axis) and is with the help of actuator 15 executed. actuator 15 is with the connecting arms 16 and 17 provided with connecting arm 16 between the mast 9 and the cylinder of the actuator 15 attacks. connecting arm 17 also engages the actuator cylinder 15 and on the other hand to the attachment of the arm member. The free end of the piston of actuator 15 Attacks this attachment. The retraction and extension of the piston into and out of the cylinder creates a shearing motion of the connecting arms 16 and 17 and thus a rotational movement of the mast with respect to the attachment 8th ,

In the mast is a vibrating block 10 appropriate. This is with the help of attached at the corners rubber blocks 27 ( 5 ) on the mast 9 attached. On the bottom is the jogging block 10 provided with eccentrics. These eccentrics are lubricated by means of an unspecified oil pump, which consists of an oil tank 23 is supplied.

The drive of the anchor driver 19 via the gears 20 in the jarring 10 are attached. The drive motors of these gears 20 are not shown and may be any known in the art engines, such as wheel motors for large digging tools. These are hydraulic motors. These gears 20 grab the pins 21 on, on the anchor taker 19 are attached or pass through it.

As can be seen from the drawings, the Rüttelblock has 10 for easy reception of the anchor driver a U-shape.

In this embodiment described above is arm element 6 over the hinge pins described above with the mast 9 connected.

In the basis of 6 and 7 In the embodiment shown, the two pivot pins used were each replaced by a turntable. In the 6 and 7 the same position numbers are used for the same parts as in the previous figures. The slewing ring (in the in 6 shown position) for the rotational movement about a horizontal axis of rotation ensures is consistent with 40 designated. The slewing ring consists of a toothed ring 41 and an engaging in the toothed ring screw 42 , slug 42 is driven in rotation by a motor not shown in detail and ensures a self-locking construction.

For the rotational movement about the vertical axis ( 6 ) provides a consistent with 45 designated turntable, consisting of a toothed ring 46 and a driving snail driving this 47 , By using the turntables shown here, the distance between arm element 6 and mast 19 be downsized. As a result, the torque occurring therebetween becomes smaller and the device more stable. This makes it possible to carry out work in even more extreme situations.

In 7 will be a detail of in 6 reproduced listed construction, at the same time changes the drive of the anchor driver 19 to be shown. In this case, only two gears 20 used with associated drive motors. As this results in a lower braking power - that is, the ability to forces from the driver 19 in the arm element 6 take, is less -, a separate braking device is provided. This consists of a wedge 49 that by a lifting device 50 is pressed, which the driver 19 clamped, so that pressure forces acting on the mast 9 and thus arm element 6 can be transmitted.

How out 7 shows, drives the anchor taker 19 the anchor rod 25 by attacking the anchor 26 in the ground. Is the anchor driver located? 19 in the desired position, the anchor taker 19 removed and the anchor 26 can be folded over in a manner known as such by the exercise of a tensile force on the anchor rod.

Also, at the free end of the mast 10 a winch 30 appropriate. This makes it possible to carry out the above-described pulling movement; that is, on the anchor rod 25 a tensile force is exerted with which the anchor 26 is folded. In addition, the load capacity of the anchoring thus obtained can be determined by the installation of measuring devices. If the anchoring does not meet the desired requirements, this can be remedied immediately. The remedy may be to remove the anchorage and place the anchor in a different position, both in orientation and depth. As a result, it is not necessary to displace a crane over greater distances, as is customary in the prior art. For example, a winch with a pulling force of about 15 tons is used.

Out 1 - 3 shows that it is possible with the invention to bring the mast in any desired position, so that the anchor can be set without special measures at any point.

According to another, not shown variant of the present invention is mast 9 not used or in shortened form and anchor taker 19 will be more stable. This can be achieved by having anchor passengers 19 is designed as a hollow profile. Is anchor operator 19 For example, a rectangular profile, this has sufficient stability, so that the mast 9 shortened or completely omitted.

According to the above, those who are aware of the state of the art can immediately imagine variants which, according to this description, are obvious and within the scope of the corresponding claims.

Summary

Device and method for setting anchorages. The device consists of a mast which is hinged to a crane with articulated arm. The articulated attachment is designed so that the rotational movement can take place in two mutually perpendicular planes. As a result, an anchor can be brought into the correct position with the aid of an anchor driver in every position of the crane. In addition, the device is provided with a winch, whereby after proper positioning of the anchor by application of a tensile force it can be checked whether sufficient force can be exerted by the anchor.
