Description

The Invention is directed to a device for recovering a Lutte with end deformable Luttenringen.

The Luttenringe are usually made of spring steel. Between the two Luttenringen extends a generally 10 m long plastic tube, the over at least one suspension bar Plastic hung can be. Such Lutten be assembled via tensioning means to Luttensträngen, which are over several hundred meters can extend. Such Luttenstränge be in the underground Mine operation for ventilation of non-permeable mine workings used. But even in tunneling such Lutten find their use.

To have Lutten fulfills her task so they are so far purely manually merged into a package and transported away. For this it is necessary, first one the Luttenringe so far oval compress, that then with the longer axis this compressed Luttenrings as a winding axle, the Lutte around the compressed Luttenring can be wound up. Finally, the second Luttenring must still compressed by hand oval and the whole wrapped Luttenpaket be tied up ready for transport.

Of the Effort for the winding of Lutten is relatively high and it needs also a certain skill of the miners around the under spring restoring force standing squeezed Luttenring keep in this configuration and then in screw in the plastic material. This effort will be particular then, apparently, considering that Luttenstränge up 2000 m and more with regard to the individual Lutten must be wound up.

Of the Invention is based on the prior art, the task, to propose a device for recovering a Lutte, which under consideration the special local Conditions in the underground Track and tunnel construction simple, easy to handle and is economically usable.

The solution this object consists in the features of claim 1.

The Device has two mutually parallel winding arms on. These winding arms are in the plane of extension of the Luttenrings to be deformed mechanically displaceable. To wind a Lutte be the winding arms in dependence of the diameter of the Lutte first distanced so far from each other that they are smooth in the extension plane the Luttenrings over this can be relocated. Subsequently the winding arms are moved towards each other, wherein the Luttenring then in the desired The circumference is compressed oval becomes. The Luttenring now has a short and a long axis. The long axis extends parallel to and midway between the Wrapping arms and is now used as a winding axis. Go berserk The wrapping arms are together with the Luttenring in the Lutte screwed in until completely wound up. At the end only needs the second Luttenring still compressed and with the wound up Luttenkörper transportable tied to become.

Of the significant advantage of the invention is that now under always cramped conditions of the underground Mining and / or tunneling manual effort is limited to a minimum. The automatic winding of Lutten can be done quickly, so that too long Luttenstränge wound up in a short time with respect to the individual Lutten and tied up for transport can be.

Of the Secure detection of the Luttenrings by the winding arms is according to claim 2 thereby advantageously taken into account that the winding arms a channel-shaped Have cross-section that opens in the direction of the winding axis is. This channel cross section, for example, by a simple U-iron be formed. But there are also other channel cross sections conceivable.

One facilitated interaction between the Luttenring and the winding arms is achieved according to claim 3, characterized in that in the winding arms transversely supporting rollers extending therefrom are incorporated at a distance to each other. This is in particular taken into account the fact that after winding the Lutte the Luttenkörper tight around the squeezed Luttenring has laid.

If Now the Luttenring is compressed a little more, this tight Facility lifted and it can the wrapping arms between the Luttenring and the wound Luttenkörper under be pulled out rolling contact with the Luttenring. The support rollers preferably extend in the middle height range of the legs of the Wrapping arms.

A perfect collapse of the winding arms against the restoring force of the resilient Luttenrings is achieved according to claim 4 characterized in that the winding arms can be displaced along a winding spar which extends transversely to the winding axis and can be rotated about the winding axis. The winding bar is sufficiently stiff to ensure the safe guidance of the wrapping arms. It can consist of a hollow profile. Conceivable, however, other profiles to ensure proper positive guidance of the winding arms.

The Relative displacement of the winding arms can in different ways and Be accomplished manner. For example, it is conceivable that at least one hydraulically or pneumatically actuated cylinder associated with the winding spar and the relative displacement of the winding arms causes. One of the underground In the meantime, however, accommodating simpler design becomes in the features of claim 5 seen. After that is at the winding spar a threaded rod provided with two opposing threaded sections, on which the winding arms associated adjusting nuts displaced are.

It is useful according to claim 6, the threaded rod manually from one end, for example by means of a hand crank or by means of a compressed air screwdriver, turned. During their rotation, the adjusting nuts slide along the threaded sections and take in this way the winding arms in one direction or the other.

of course is it is also conceivable that the threaded rod are rotated by a motor can.

In Another embodiment of the invention is according to the features of the claim 7 the winding beam to a local fixable carrying unit hinged and under the influence of a motor Drive unit provided. This support unit can be moved independently be or part of a sloppy or hanging Form transport unit. The motor drive unit can be with compressed air or hydraulic acted upon engine. Of course it is also an electric motor conceivable.

The Invention is described below with reference to an illustrated in the drawings embodiment explained in more detail. It demonstrate

1 in the front view in the scheme of a device for recovering a Lutte in different operating positions;

2 a vertical cross section through the representation of 1 along the line II-II and

3 a winding process in four different winding positions a), b) c) and d).

In the 1 is a device 1 to the mountains of a Lutte 2 with end deformable Luttenringen 3 . 3a designated. The Lutte 2 with the Luttenringen 3 . 3a goes out schematically 2 out.

The device 1 comprises two mutually parallel extending winding arms 4 with one from the 2 recognizable channel-shaped cross-section. Every wrapping arm 4 is made up of two thighs 5 and one the thighs 5 connecting arcuate section 6 together. Between the thighs 5 extend at a distance from each other support rollers 7 , The open pages 8th the wrapping arms 4 are facing each other.

One end of the wrapping arms 4 is on a winding spar 9 via a console 10 forced out. With the consoles 10 is each an adjusting nut 11 connected by a threaded section 12 . 13 a threaded rod 14 interspersed in the winding spar 9 is provided. The threaded sections 12 . 13 run in opposite directions. End is the threaded rod 14 in camps 15 held.

At one end of the threaded rod 14 is a bevel gear pairing 16 , About this bevel gear pairing 16 can with the help of one to the connection 25 attachable unspecified hand crank or a pneumatic screwdriver the threaded rod 14 be turned so that the winding arms 4 move towards or away from each other.

The winding spar 9 is at a locally fixable, for example, a transport device associated carrying unit 17 rotatably mounted. He can with the help of a compressed air motor 18 and a downstream transmission this 19 around the axis 20 be turned freely.

To get out of the 2 recognizable Lutte 2 according to the arrows 21 To be able to wind up, first the winding arms 4 according to the 1 and 2 in the plane EE of the Luttenrings 3 about this procedure. This encompass the wrapping arms 4 the Luttenring 3 ,

Subsequently, by turning the threaded rod 14 the wrapping arms 4 moved towards each other, so that the first circular Luttenring 3 according to the dot-dash representations of 1 oval deformed. The compressed Luttenring 23 then has a longer axis 24 , which at the same time the winding axis for the Lutte 2 forms and which is coaxial with the axis of rotation 20 of the winding beam 9 extends.

After the collapse of the Luttenrings 3 to the desired oval cross section 23 becomes the winding spar 9 according to the 3 rotated, so then according to the arrows 21 of the 3 the Lutte 2 in a train around the winding axis 24 can be wound up.

Is that Lutte 2 completely wound up, the Luttenring becomes 23 opposite the wound body 26 ( 3d ) is further compressed in its plane of extension EE, so that then the winding arms 4 under support of the support rollers 7 at the compressed Luttenring 23 easily from the area between the Luttenring 23 and the wound body of the wound 26 can be removed.

All you need is the other Luttenring 3a compressed by hand and with the Luttenkörper 26 wrapped Lutte 2 to be tied up for transport.
