Description

The present invention relates to a cane guide and an arrangement of a cane guide on a cane. Furthermore, the invention relates to a makeshift construction, which comprises a stick tree guide or arrangement according to the invention, the use of the stick tree guide and a method for forming a makeshift construction.

Stock trees are used in the prior art in the erection of steel lattice towers and other structures. Stick trees of this type are used in particular in demanding terrain, such as forests or mountain regions, as a replacement for conventional cranes or similar lifting devices. Cane trees thus represent makeshift devices that usually use an already existing part of a structure as a suspension. When in use, the stick tree is usually connected at its ends to the mast or construction to be erected by means of tension cables.

Stick trees known in the prior art have the disadvantage that they can only be used up to a certain construction height. Repositioning is then required, which usually requires laborious steps.

It is therefore an object of the present invention to overcome this disadvantage of the prior art and to provide a stick tree whose height in can be adjusted in a simpler and safer way when erecting a mast construction or a similar construction.

This object is solved by the subject matter of the independent claims. In particular, it was surprisingly found within the scope of the present invention that a stick tree guide can solve the task described above. This cane tree guide can be used in a cane tree arrangement as well as in a makeshift construction. The object of the present invention is achieved in the same way by using the stick tree guide and a method according to the invention for operating a makeshift construction.

The present invention relates to a stick tree guide comprising a frame construction and a receiving area formed within the frame construction.

Provision is preferably made for the receiving area to be set up to receive a stick tree and to enable a movement of the stick tree guide along the longitudinal extension direction of the stick tree. The geometry of the receiving area can be adapted in particular to the stick tree used in each case. In order to be able to develop the advantages of the present invention, it is preferred that the receiving area of the tree guide is designed to enclose the tree, in particular to completely enclose it.

The cane guide allows for stabilization of the cane tree, allowing easy changing of the height of the cane tree.

In particular, the receiving area of the tree guide can enclose the tree with essentially no play, so that when the tree with the tree guide is arranged as intended, essentially only a linear relative movement between the tree and the tree guide is possible.

The direction of longitudinal extension of the stick tree can alternatively be referred to as the guiding direction. In particular, the stick tree guide according to the invention Have guide direction, which extends in the intended use of the stick tree guide substantially parallel to the longitudinal direction of the stick tree.

If necessary, it is provided that the frame construction of the stock tree guide comprises an upper part and a lower part as well as connecting struts connecting the upper part and the lower part. In particular, the upper part and the lower part are designed to enclose the stick tree.

If necessary, provision is made for sliding elements to be arranged on the side of the frame construction facing the receiving area, with the sliding elements forming contact areas for contacting the stick tree. In particular, the contact areas can delimit the receiving area. If necessary, the sliding elements can partially or completely form a contact area.

When the tree guide is used as intended, the contact areas can rest on the tree or on one or more outer or side surfaces of the tree. This enables a safe and stable guidance of the stick tree.

If necessary, it is provided that the sliding elements are arranged to run essentially parallel to the direction of longitudinal extent of the stick tree. The sliding elements can be struts, for example, which are arranged on the inside of the frame construction. If necessary, provision is made for the sliding elements to be arranged so as to run essentially parallel to the guide direction of the stick tree.

If necessary, it is provided that the sliding elements comprise a contact section and an end section at least on one side, preferably both sides, the end section being arranged at an angle to the contact section and pointing away from the receiving area. In this case, the contact area of the pole guide can be formed by the contact sections of the sliding elements.

The end sections pointing away from the receiving area, and thus the end sections pointing outwards, are preferably used in order to prevent the tree guide guide from unintentionally hooking into the tree. This is particularly preferred when the tree is a lattice mast construction open to the outside.

If necessary, it is provided that the angle between the contact section and the end section is between 5° and 60°, preferably between 5° and 30°. Simultaneously or alternatively, the angle can be between 5° and 60°, preferably between 5° and 30° in relation to the direction of longitudinal extent of the stick tree.

If necessary, at least one fastening element is arranged in the upper part or in the lower part of the frame construction of the pole guide.

The invention also relates to an arrangement of a stick tree guide according to the invention on a stick tree, with the stick tree being arranged in the receiving area of the stick tree guide. In this arrangement, a relative movement between the tree guide and the tree is preferably possible essentially only along one degree of freedom, namely in particular along the longitudinal extension direction of the tree.

If necessary, it is provided that the cane tree has at least three side surfaces which run along the direction of longitudinal extension of the cane tree, and that the tree guide comprises a number of contact areas corresponding to the number of side faces for the planting of the tree. The contact areas can be formed by sliding elements on the side of the frame construction facing the receiving area.

This means that the receiving area of the cane guide can have three contact areas if the cane has three side surfaces, and also four contact areas if the cane has four side surfaces.

In particular, the geometry of the receiving area of the tree guide can be adapted to the outer profile of the tree. For example, the receiving area can have an essentially triangular cross section if the stick tree has a triangular outer profile. The receiving area can also have a quadrangular cross-section if the stick tree has a quadrangular external profile.

• 3 a schematic view of a makeshift construction with the stick tree guide of the embodiment, wherein the stick tree is in a first position; and
• 4 the schematic view of a makeshift construction 3 , where the cane tree is in a second position.

Figures 1 and 2 show schematic representations of an embodiment of the stick tree guide 4 according to the invention in different views. The two figures show the same construction, this will be explained for better clarity in a common description.

The stick tree guide 4 according to this exemplary embodiment comprises a frame construction 1 which surrounds a receiving area 2 . The frame construction 1 in turn comprises an upper part 6 and a lower part 7 which are held together by three connecting struts 8 . Upper part 6 and lower part 7 are also through Sliding elements 9 connected, in this embodiment, six sliding elements 9 are provided.

The receiving area 2 of the pole guide 4 of this exemplary embodiment is designed to accommodate a pole 3 with an essentially triangular outer contour. In the Figures 1 and 2 the cane tree 3 is shown in dashed lines since it does not form part of the cane tree guide 4 .

Corresponding to its essentially triangular shape, the stick tree 3 has three side faces 17 that run along its longitudinal extension direction 5 . The floor tree 3 shown here is a mast construction.

Corresponding to the three side faces 17 of the tree 3, the tree guide 4 has three contact areas 18 at the edges of the receiving area 2, against which the side faces 17 of the tree 3 bear. The contact areas 18 are formed by the contact sections 10 of the sliding elements 9 , with two sliding elements 9 running essentially parallel to the longitudinal extension direction 5 of the stick tree 3 being provided in each of the three contact areas 18 .

In addition to the contact section 10 running parallel to the longitudinal direction 5 of the tree 3, each of the sliding elements 9 has an angled end section 11 at both ends, which in this example is at an angle a of approximately 10° relative to the longitudinal direction 5 or to the contact section 10 from the receiving area 2 points away. The angled end sections are intended to prevent the sliding elements 9 from hooking into the lattice structure of the cane tree 3 when the guide 4 is moved along the cane tree 3 .

Due to the configuration of the receiving area 2, the pole guide 4 can essentially only be guided in a linear movement along the pole 3, thus with essentially only one degree of freedom. "Essentially" in this context means that there is some play for the inventive Function is permitted as long as the stability of the guide is not affected.

In this exemplary embodiment, fastening elements 12 are provided in the form of exemptions on the frame structure 1, in particular on the upper part 6. These are used to attach connecting elements 13, as explained in more detail below.

The direction of longitudinal extension 5 and the guiding direction 21 of the pole tree guide 4 run essentially parallel to one another in this exemplary embodiment.

In other embodiments that are not shown, the tree guide 4 can have other geometries. In particular, the size and shape of the geometry of the receiving area 2 can be adapted to the tree used in each case, without deviating from the basic idea of the present invention.

The combination of the stick tree guide 4 and the stick tree 3, as shown in Figs Figures 1 and 2 shown also provides an embodiment of an inventive arrangement and use of the invention.

Figures 3 and 4 show schematic views of a makeshift construction with the pole guide 4 of the previously described embodiment, with the pole 3 in a first and a second position. The construction details of the stock tree guide 4 are not explained again at this point. Accordingly, the stick tree guide 4 in the Figures 3 and 4 only shown schematically.

A mast section 14 is shown, the mast section 14 being a mast under construction. The mast is built in mountainous terrain, so that no external cranes or comparable lifting devices are available for its construction. Therefore, as an alternative, a stick tree construction as in the Figures 3 and 4 used, which is used to raise other mast sections. This entire arrangement, comprising the stick tree 3, the stick tree guide 4 and the mast part 14 is to be understood as a makeshift structure within the meaning of the present invention.

A pole tree 3 is attached to the mast part 14 . In this exemplary embodiment, the connection between the mast part 14 and the boom 3 is realized with connecting means 13, which are designed as belts. On the one hand, first connecting means 13' are arranged between the mast part 14 and the upper end 15 of the pole 3, and on the other hand second connecting means 13" are arranged between the mast part 14 and the lower end 16 of the pole 3. The first connecting means 13' are fastened by means of clamping elements 19, in this The first connecting means 13' are connected to the mast part 14 at the connection level 22. The connection level 22 is the level on which new mast elements 23 are placed, as in FIG 4 shown.

The second connecting means 13" are connected to the mast part 14 below the connection level and are designed as a continuous tension element, which is guided from a fastening point 24 via guide rollers 25 at the lower end 16 of the boom 3, on the mast part 14 and in the area of the ground to a winch 26. By rolling up the second connecting means 13" onto the winch 26, it is shortened and the tree 3 is raised.

In addition, the stick tree guide 4 of the invention is arranged on the stick tree 3 in this makeshift construction according to the invention. This is located between the upper end 15 and the lower end 16 of the floor tree 3 and is held in position by third connecting means 13‴, also in the form of straps with tensioning elements 19. The connecting means 13 ‴ are fixed in the connection plane 22 of the mast part.

With the makeshift construction, further mast elements can be raised after assembly and placed in the desired position until the desired height of the mast is reached.

The makeshift construction is provided in particular by inserting the pole 3 into the pole guide 4 and fastening the pole 3 and guide 4 to the mast part 14 by means of connecting elements 13 . This represents a first position of the makeshift construction.

After further construction of the mast part 14, shown in 4 Due to the additional height 20, the length of the boom 3 is no longer sufficient to use it sensibly to raise further mast elements. It is therefore necessary to raise the floor tree 3. This is done by changing the length, in particular shortening or rolling it up onto the winch 26, of the second connecting means 13", as a result of which the boom 3 slides upwards on the boom guide 4 along the guide direction 21. The second connecting means 13" acts as a cable pull. The stick tree guide 4 provides essentially position-stable guidance. After moving the boom 3, it is in a second position, which is sufficient to be able to raise further elements of the mast with the boom.

Both in the first position and in the second position, the stick tree guide 4 is arranged spaced from the ground.

If necessary, the position of the pole guide 4 can also be changed in a further step. In particular, the floor tree guide 4 can be attached to the new connection level with the connecting means 13‴. The position of the first connecting means 13' and the second connecting means 13'' can also be changed.

The boom 3 can also be inclined (not shown) in order to use it as a crane-like structure. A lifting device can be provided for lifting mast elements.
