Description

Technical area

The invention relates to a clamping device for a substantially elongated component, in particular a mast or pile, for the transport and / or assembly and / or disassembly of the elongated component by means of a construction vehicle, in particular a wheel loader.

Furthermore, the invention relates to a construction vehicle with a clamping device for clamping an elongated component, in particular a mast or pile.

Furthermore, the invention relates to a method for mounting an elongated component, in particular mast or pile, with a construction vehicle and a clamping device attached thereto.

It is often necessary to mount masts, such as light poles, on construction sites and thus on a relatively difficult to access terrain. For this purpose, the light towers to be set up are transported to the construction site, for example with a truck, and the light masts are subsequently unloaded by means of a crane. With the crane, the light poles can also be picked up at one end, erected and moved to the mounting location. This is often associated with considerable difficulties. The range of the crane is very limited. Thus, very long crane set-up times and associated labor costs and material costs are often to be taken into account. Furthermore, the light pole can be picked up by the crane only at one end, so that it can sway around when moving to the mounting location. This is associated with dangers for construction workers and complicates the alignment and insertion in the mast quiver.

After inserting the light mast in the mast quiver has a fitter usually attach attachments such as lanterns, signs or antennas by means of a platform in the upper part of the light tower.

State of the art

The DE 91 06 836 U1 describes a working device for dismantling masts, piles, columns or pillars. It is provided that the working device has a connection piece with a connection joint for connection to a mobile lifting device and a carrier connected to the connector. The carrier is provided with at least two spaced-apart gripping tongs with pliers drive. The working device is pivotable by means of a pivot drive in the connection joint from a pivot position in which the grippers are vertically above one another, into a pivot position in which the grippers are arranged side by side.

DESCRIPTION OF THE INVENTION: Problem, Solution, Advantages

The object of the present invention is to propose a clamping device for a substantially elongated component, in particular a mast or pile, for transport and / or assembly and / or disassembly of the elongated component by means of a construction vehicle, the clamping device being particularly flexible and cost-effective and can be used and thus facilitates assembly of the elongate member in comparison to known from the prior art solutions.

According to the invention, a clamping device for a substantially elongate component for transporting and / or mounting and / or dismantling the elongated component by means of a construction vehicle is proposed for this purpose. The clamping device has at least one first clamping means and one second clamping means for clamping the elongate component. The elongated component may be, for example, a mast, in particular light tower or lamppost, a post, a post or a pillar. Furthermore, the clamping device is preferably designed for attachment to the construction vehicle, in particular on an off-road construction vehicle. Particularly preferably, the clamping device for attachment to a wheel loader, in particular telescopic wheel loader is formed.

According to the invention, the clamping device has at least a first fastening means and a second fastening means for fastening the clamping device to the construction vehicle. Furthermore, the clamping device has at least two clamping means, namely a first clamping means and a second clamping means, for clamping the elongate component, wherein both fastening means are arranged in a region between the first and the second clamping means.

With the fastening means, the clamping device on the construction vehicle, for example, at the end of an attached to the pivotable arm of a wheel loader attachment, for example, attached to a blade, forklift or pallet fork.

The clamping means comprise or at least partially clamp the elongated component circumferentially. A full clasp or clamping of the elongated component is not absolutely necessary. The two fastening means are in the area between the first and the second clamping means arranged so that an imaginary direct connecting line of the two fastening means extends between the first and the second clamping means.

The clamping device according to the invention allows a particularly stable recording of the elongate member, such as mast or pile. Furthermore, the clamping device according to the invention serves not only for setting up, but also for receiving the elongate member, for example, a truck as well as for transporting the elongated member to the mounting location.

In contrast to known from the prior art devices, the crane for unloading and erection of the mast can be saved. Furthermore, additional means of transport for moving the pylons on the construction site can be saved. A work platform for attaching attachments, such as lanterns, signs or antennas, is also not required. Up to now necessary working steps, such as intermediate storage, charging, unloading, upgrading and disarming crane and associated labor costs and material costs, can be saved by the use of the clamping device according to the invention.

The fact that the elongated component is clamped only once, the elongated component is also spared. Dirt and frequent scratch marks that occur in known in the art solutions are much lower with the clamping device according to the invention. The jig can be used for example by means of a wheel loader, which is usually used anyway on most construction sites. Thus, no additional or special construction vehicles or tools are required.

Preferably, it is provided that the first clamping means and the second clamping means are arranged in a region between the first fastening means and the second fastening means. This is to be understood as meaning that an imaginary direct connection line of the two clamping means runs between the two fastening means. Thus, not only the two fastening means are preferably arranged in a region between the first and the second clamping means, but also the two clamping means are arranged in a region between the two fastening means.

Preferably, the two fastening means and the two clamping means are arranged to each other such that the two respective mental direct connection lines intersect, particularly preferably centrally and / or vertically.

Preferably, the chuck has a third chuck disposed between the first chuck and the second chuck. Particularly preferably, all three clamping means are arranged along a straight line. The first and second chuck means are the outer chucks and the third chuck is preferably located midway between the first and second chucks. Furthermore, it is preferably provided that the third clamping means is arranged on the imaginary direct connecting line of the two fastening means. Particularly preferably, the third attachment means is arranged on the intersection of the mental connection line between the two attachment means and the mental connection line between the first and the second clamping means.

The first clamping means and the second clamping means are preferably connected to each other via a receiving rail for receiving the elongate member. The receiving rail is designed such that it laterally comprises the elongated component. For this purpose, the receiving rail may for example be U-shaped or V-shaped or have a U-shaped or V-shaped cross-section. The receiving rail thus serves for the mechanical connection of the two clamping means with each other as well as for fixing the elongate member, whereby slipping of the elongate member is prevented.

Furthermore, it is preferably provided that the first fastening means and / or the second fastening means is tubular. As a result, the clamping device can be received in a particularly simple manner by the construction vehicle. For example, the tubular-shaped fastening means can serve to receive a loading fork or pallet fork of a wheel loader. For this purpose, the cross section of the tubular fastening means can be round or square.

Preferably, the two fastening means are elongated. By this is meant that they have a greater length than width. Particularly preferably, the two attachment means have a length which is greater by a multiple than the width thereof. By means of screws and / or clamps, the clamping device can be fixed, for example, on the forklift or pallet fork of the wheel loader.

The clamping means may be formed mechanically, electrically and / or hydraulically. For example, straps may be provided, by means of which the elongated component is fixed in the receiving rail. By means of electrically or hydraulically formed clamping means, the reception and / or clamping of the elongated component can be further automated.

Preferably, the two fastening means are connected to one another via at least one strut, particularly preferably via at least two struts. Under a strut is a mechanical connection means to understand. Furthermore, it is preferably provided that the at least one strut is also connected to the receiving rail. For example, the at least one strut can connect both fastening means as well as the receiving rail extending between the two fastening means. Also, the at least one strut can be divided into two parts. For example, a portion of the at least one strut connect the receiving rail with the first attachment means and the second portion connect the receiving rail with the second attachment means.

The two fastening means are particularly preferably connected to each other via two struts, wherein the two struts are spaced and arranged parallel to each other. The two fastening means are preferably arranged perpendicular to the at least one strut or the at least two struts.

Furthermore, additional struts are preferably provided for connecting the fastening means with the clamping means. For example, the first clamping means may be connected to the first fastening means via a strut. Additionally or alternatively, the first chuck may be connected to the second attachment means via a strut. Additionally or alternatively, the second chuck may be connected to the first attachment means via a strut. Furthermore, the second clamping means may be connected to the second fastening means via a strut. By using these additional struts, the jig is made more stable and stiffer. Particularly preferably, it is provided that the at least one strut between the two fastening means is arranged substantially on a plane with the struts between the clamping means and the fastening means. Particularly preferably, the struts between the clamping means and the fastening means may be arranged diamond-shaped.

According to the invention, a construction vehicle, in particular a wheel loader, is also provided for transporting and / or assembling and / or disassembling an elongated component, in particular a mast or pile. For this purpose, a pre-described clamping device for clamping the elongate member is attached to the construction vehicle.

Preferably, the clamping device is attached to an attachment, in particular a loading fork or pallet fork, of the construction vehicle.

According to the invention, a method for mounting an elongated component, in particular a mast or pile, with a previously described construction vehicle is furthermore provided, the method having at least the following steps:

• a) attaching the clamping device to the construction vehicle; and
• b) placing the clamping device on the elongate member; and
• c) clamping the elongated component to the clamping device; and
• d) picking up the elongated component; and
• e) transporting the elongate member to an assembly location; and
• f) erecting the elongate member in a substantially vertical position; and
• g) insertion of the elongated member in a designated mounting hole, in particular in a mast quiver.

With the method according to the invention thus additional means of transport and construction devices can be saved. For mounting the elongate component, for example a light mast, only a construction vehicle, which is already normally used on the construction site, is required, in particular a wheel loader.

For example, the light poles can be transported by means of a truck. The light poles do not have to be unloaded from the truck and temporarily stored with a crane or other device. With the construction vehicle and the attached chuck a light pole can be picked up directly from the back of the truck. For this purpose, the jig is placed on the light pole, clamped the light pole and then lifted from the bed. The construction vehicle can then transport the light pole directly to the assembly location or installation site. For this purpose, the clamping device is left in the horizontal or preferably brought into an oblique or semi-upright position. As a result, the light pole can be transported in difficult terrain with the construction vehicle.

Due to the fixed clamping the light mast vibrates little or not at all. At the Mounting location of the light pole is placed in a substantially horizontal position at a freely selectable working height, so that attachments such as lanterns, signs, antennas or other attachments can be mounted before setting up the light mast.

Subsequently, the light mast is pivoted with the jig of the construction vehicle in a substantially vertical position, so that the light pole hovers over the mast quiver. In the next step, the light pole in the mast quiver can be set so far that further connections can be made. Finally, the light pole is lowered so far that it is in the bottom of the mortar. With the construction vehicle, the still muted light pole can be aligned. After fixing the light mast, the clamping means can be released and the construction vehicle with the clamping device arranged thereon receive the next light mast.

With the method according to the invention, the elongated component can be used during the entire assembly process, i. H. remain clamped after the single clamping in step c). Intermediate settling and or loosening of the clamping is not required. All process steps can be performed with the same construction vehicle and the fixture attached thereto.
