"Device for attaching loading devices for the

Shaft sinking "

The invention relates to devices for attaching and intermittently lowering working on the shaft floor Loading devices when sinking mine shafts and a method made possible by their design for conveying away what has been shot in on the bottom of the shaft Heap,

When sinking shafts, the debris shot in on the shaft bottom should be removed as quickly as possible will. Mechanical loading devices have been developed for this purpose. The majority of these are currently in use Chargers is special for use

when sinking circular shafts f * are carried by platforms that follow the course of the sinking process subsequently be lowered into the shaft.

The invention is a loading and removal method for the shot in pile using a mechanical loading device created, daa particularly suitable for use when sinking shafts of rectangular Cross section is.

The device forming the subject of the invention for attaching and gradually lowering the charger consists from a rigid rectangular frame suspended in the shaft, a pair of which are opposite one another Elements form a roadway, which one along this movable bridge carries, on which in turn a carriage is mounted, which carries a reel, on which normally a gripper is attached.

In a further embodiment of the invention, pressure cylinders are arranged at each of the ends of the frame and the bridge, the carriage and associated mechanisms are located below the upper level of the frame, therefore can be covered so that it then becomes a work platform

forms, from which the expansion of the shaft can be introduced.

3) he invention further comprises a method for conveying of hereingeschossenem debris during the drilling of a well, which is equipped with steel frame, wherein the one gripper supporting frame is attached to one of the expansion frame, during a following expansion frame is embedded in concrete and for concrete used for this purpose sets and the frame is lowered following the progress of the sinking with the progressive use of ever deeper supporting frames for its attachment.

According to the invention are also on the bridge and the car arranged by compressed air or in other appropriate V / ice driven motors, which in turn, the drive assemblies for the bridge and the viagen drift and in in the patent. ... ... (patent application H 43 297 20a / 11) described manner are formed.

The details and further features of the invention emerge from the following description of a preferred embodiment the same using the sehein & ti see illustrations.

lig. 4 illustrates one embodiment of the method to lower the overall arrangement.

In all figures, with the exception of Mg. 4, is the Gripper omitted "

As can be seen from the figures, there is the rectangular one Frame 2 essentially consists of crown girders 3. Its size is dimensioned so that it fits tightly into the cross-section of the shaft fitted, but in its longitudinal or transverse direction tiltable isο Bs is also possible to frame of other than the described and illustrated embodiment to use without deviating from the basic idea of the 'invention'

The beams 3 forming the long sides 4 of the frame are designed as a roadway for wheel sets 5, which a © extending between these beams bridge structure 5 wear. The wheel set assembly 5 on one side of this bridge structure is powered by a compressed air motor 7 driven, through which the bridge structure 6 from one side of the frame 2 to the other side can be proceeded.

On the bridge structure 6, a carriage 8 is mounted, which has a reel 9 and a drive motor 10 for a Gripper 11 of the "Kaktui" type carries »This car is with equipped with an appropriately designed motor, through which it can move in one direction or the other can be moved to the bridge construction.

The drive arrangement for at least the carriage 8 is essentially that described in the aforementioned patent described manner trained, line such training results, as has been shown, a minimum amount of slip between the drive wheels 12 and the roadway 13 »How as can be seen from the later explanations, an additional load on the wagon can be provided in order to

by the contact pressure between the drive wheels 12 and to raise the rails 13 on which the carriage runs.

In the figures, a special arrangement is shown in which at least some of the. on the Cart-mounted apparatus located above the upper level of the frame 2. The arrangement can of course can easily be taken so that the entire apparatus is below the upper level of the frame 2 is so that its interior can be covered and then forms a standing surface from which others Works than that of unloading the debris in the shaft can be carried out.

At each of the top corners of the frame are adjacent this swiveling telescopically extendable tubes with clamping heads 14 arranged, which with their other ends are detachable the webs of the profile extensions 16 of the sun include » In addition, in the vicinity of all corners of the frame 2, outwardly directed air cylinders 17 are arranged. The pipes with If desired, clamping heads can also be fitted with suitable Rope slings of the same length must be replaced.

During its use, during which the entire device 1 is held below the expansion frame 16, the frame 2 is carried by the extension frame 16 brought in last and held by the pipes with clamping heads 14, During the loading process, the air cylinders 17 are extended at the corners 15 of the frame 2 and are braced in this way the frame firmly against the joints of the shaft in its position. The air cylinders can automatically, if necessary together with the application of other units of the overall apparatus be designed to be actuatable with air. Palis, like that possible is, at least some members of the frame 2 consist of beams of tubular profile, they can be so formed be that they form part of the air cylinders or they are housed inside the tube profiles.

In the example described above, there is talk of the use of compressed air as the drive means, however it is of course also possible within the scope of the invention, to use other drive means.

With the aim of increasing the working depth of the device and, if necessary, installing the next extension frame to facilitate, like the one from Pig. 2 it can be seen, the gripper 11 and its generally from the days

loosened and lowered to the bottom of the shaft. In this case, the I _r agseil 18 and the hoisting rope 19 can be used to carry the loading device 1, while the tubes Η carrying the clamping heads are extended and, after these have been fixed, the reel and the conveyor rail are used, in order to bring the expansion frame 16 into the position enabling it to be installed

It is also possible to use reels or reels arranged elsewhere to pull the frame the progress of mining.

Then the gripper assembly 11 can be struck again and the download to be continued «

After the concrete in which the bottom support frame 16 is embedded has sufficiently set, the entire device is lowered and then hung on this lowest frame in the manner described above, the reel rope and the shaft hoisting rope are used for this purpose. Even in cases in which Expansion frame 16 must be installed leading the frame 1, it is by actuating the conveyor and the

Reel rope possible to tilt this in two ways so that it can pass the spaces between the expansion frame, and the Eohrklemmen 14 to after
The following extension frames can be attached below
