Description

[0023] Further details and advantages of the subject-matter of the invention can be found in the following description of the corresponding drawing, in which a preferred embodiment with the necessary details and individual parts is shown. The following can be seen:

[0024] FIG. 1 shows a working stage with telescopic pipe in a retracted position,

[0025] FIG. 2 shows a working stage with telescopic pipe in an extended position,

[0026] FIG. 3 shows a shaft excavator with console,

[0027] FIG. 4 shows a shaft excavator in a different position,

[0028] FIG. 5 shows a shaft excavator with swivel mechanism,

[0029] FIG. 6 shows the view into a boom,

[0030] FIG. 7 shows a boom in perspective view,

[0031] FIG. 8 shows a working stage with an additional working platform in front view and

[0032] FIG. 9 shows a perspective view of a working platform shaft excavator.

[0033] FIG. 1 shows a working stage 1 for the installation of fixtures in vertical shafts in mining and tunnelling with three working platforms 2, 3 and 4. Working stage 1 has a pipe 8, 9 positioned in the longitudinal axis 7. The pipes are designed to be telescopic, with the inside pipe 9 retracted here, so that the height of the shaft excavator 5 can be adjusted by moving the inside pipe 9 in the direction of the longitudinal axis 7. In the illustration shown in FIG. 1, the shaft excavator 5 is located directly below working stage 1.

[0034] In comparison to this, in the illustration according to FIG. 2 the inside pipe 9 is shown in a downward extended position, so that the shaft excavator 5 can be used down to the bottom of the shaft 27. This consists of ensuring that the blasted broken material is unloaded and removed by means of buckets not shown here after drilling and blasting the bottom of the shaft 27.

[0035] According to FIG. 3, console 15 is to be connected to inside pipe 9 or the underside 14 of the lowest working platform 13neither of which is shown here. On this console 15, in turn, the carriage, which cannot be seen here, can be moved and thus ensures the movement of the shaft excavator 5 with the boom 17, consisting of an upper part 18 and a lower part 19. The latter are connected to each other via joint 33. The handle 21 is connected to the lower part 19, at the end of which the tool 22, to which the tool 20 in the form of a backhoe bucket, is attached on the end opposite the boom 17. A quick coupler 32 may be used to change this tool 20. Cylinders are marked with the reference marks 24, 25 or 33, 34.

[0036] FIG. 4 in a different position shows otherwise the identical shaft excavator with the slide 16 that can be moved on or under console 15 in the direction of its longitudinal axis 36.

[0037] FIG. 5 shows the assembly for the shaft excavator 5 again with the console 15, on the underside 37 of which the shaft excavator 5 can be moved by means of slide 16. Two rotating and swivel devices 38 and 39 allow the shaft excavator 5 to be adjusted to almost any position.

[0038] A view into boom 18 is shown in FIG. 6 with a mounting opening 40 and in particular a view of the tubes, one of which is marked as 26 as an example, here the connection point for the handle. Cables 26 are therefore positioned in housing 28 of boom 17 and are therefore optimally protected.

[0039] Boom 17 is shown again in FIG. 7 with the bulkhead panel 41.

[0040] The subject of FIG. 8 is the variant of the invention for a working stage 1 with an additional lowest working platform 13 below the working platforms 2, 3, 4. The additional working platform 13 is connected via ropes 30, 31 to the working stage 1 with its three working platforms 2, 3 and 4. At the bottom of the shaft 14 is the shaft excavator 5, which is already very close to the bottom of the shaft 27.

[0041] This is illustrated again in FIG. 9 with the shaft excavator 5 below the working stage 13 with its various installations such as a railing 43 and the connections 45, 46 for the ropes not shown here.
