In Fig. 1 a radial drilling machine according to the ßrfindung yes a side view in a schematic representation is shown, -It. The machine has, in a manner known per se , a column 1, which can be moved up and down on the underframe 2 in the direction of the file 3 and is moved up and down and carries the roller box 4 on its upper linden tree and her -), elienden Mhrung # rem according to arrow 5 of the iluslegers 6 with the ßinrko2f '?

According to the invention, at least two planar guide surfaces extending in the direction of the column are provided on the outer circumference of the column, which are superimposed in pairs. The column in this case may have a guerschnitt rechtecxigen OAER quadrutiscaen, as shown in Fig. 2a bel 11 is 3ezeigt. This cross-section can also be rhombic, or it can have the shape of a white, as in iig. 2b is shown at .12. With the arrangement according to 2ig. 2c, the column in turn has a recessed surface 13-, although two lateral approaches 15a, Ab are provided. FIG. 2d again shows a square layout 14 for the column 3o, outside the arrangement according to 2ig. 2e Msits a profile in the shape of a two-sided triangle. At least two of 2inrunarolls 15a, 15b, 16a, Ibb (see Fig. 1) are assigned to this doorway flacaenabscinituei for guiding the pillar, the arrangement being such that each guide roller rests on a guide surface section only assigned to it and is self-contained passing on this. The same arrangement can also be used for moving the boom. With the arrangement according to Ky. 2a the pairs of guide rollers are denoted by 15 ', 151a or 161, 161a in the embodiment according to FIG. 2b with 15 ", 1511a, 16111 1611a and in the embodiment according to FIG. 16111a. In the 14 # -Usführunt7 "sform according to FIG. 2d, not two pairs of guide rollers but four such pairs 17a, 17b, 171a, 171b, 17" a, 1711b, 17t "* a, 171b are provided. With the from £ -dnrun.-Isform according to Fig. 2g has the column 50 Ansu- # Itze 51a, 51b, the mit'F'in'rungsrollen 52a, 52b, 53a, 53b zusaumenwirken.

It can be seen from the drawing that when using a profile in the form of a two-sided triangle, the arrangement can expediently be made in such a way that the longer axis lies in the direction of the upward forces. This results in a particularly high and favorable rigidity. In the profile shape shown in FIG. 2e: the outer circumference of the hollow profile 18 has the shape of a two-sided triangle with a defined axis of symmetry 19, while the hollow space 2J ä,) is formed that on corresponding approaches 20aj; Öroer with i, -reisf,) rmi, -e-, n .. "aerse.initt. The 2orm of the outer circumference and the training of the B, #hran- des r '£' ---, nlprifils result in a

.Z , larger itiandst- # rxe of the # 3aale or Jas Auslegers at the 3 -1 , which in the b3s-Diideren lia3e by adding -, # and printing

zD are sirucnt, from which sica e # _ne ernl -) 'lite bending stiffness of the element concerned results. In addition, this results in a particularly favorable torsional strength, which is not found in the known, comparable arrangements. As mentioned above, the profile is designed in such a way that round bodies such as motors 21 etc. can be accommodated in the element concerned. You can also provide cusps 12, 2 on the profile, which can be used as cooling fins for the motor, if any, or as a machining support. For special stiffening, the profile can be designed as a double-walled hollow body or be sintered with W.uerrippen. The embodiment according to FIG. 2e is produced by the so-called hot extrusion process. However, you can also assemble the column and / or the boom from several 3iien .9rofilpartien by welding together, such as dB * in Pig. 4a is shown in which the two parts 23a, 23b of the protector are welded to one another at 23c.

The Führil) -n.-zsfläohenabse-center on the oaule and / or the boom can be made of hardened L, '1: ic # lenabso-inits on the outer circumference of the entering Alementgsbestetioni bie, Jedoon can also from hard S.tanlleiAter-i or state bands, as z.ß. in Pil. 2b at 24a,; ##, 4be # 24a, 24d or In Me. 2 £ at 25 #ezei # - t are. These jtanl strips or steel strips are screwed, glued or the like on the circumference of the column or boom, for example by bracing, pressing in, compressing. attached. In the embodiment according to FIG. 2f , grooves 25a, 25b are incorporated on the outer circumference of the profile 26 , in which the adhesive is used to fasten the steel strips

25 on the profile is used.

The leadership roles can also be compared to the assigned

arranged guide surface section on the column by means of an eccentric arrangement can be readjusted in a known manner.

when the boom as in the column -can be two in the axial Hicntung vorsenen storage Übereinander- or spaced Gru_ppen of bearing bodies which each consist of two pairs of bestenen solciieti bearing bodies, wherein the Anordnun, - is concerned that both - so Bearing body gaare of the lower or rear group are designed as ##, v # 'ilzlagerkÖrper, e.g. iijllen and the one bearing body pair of the upper part or the front üraope is formed by a sliding bearing range: #c, which exits from one of the circumference of the column. #rectiend # "- ewilbte., 1 sliding jaw consists. A s-, lene sliding- forces are absorbed by the sliders, while without drilling pressure, the sliders are relieved by the weight of the various machine parts. The plain bearings Annen can also be designed in any other way. The slide bearing section can be opposite a clamping device which contains a Kleamstück, which is known per se with the aid of a lever

or a screw or mechanical, pneumatic, hydraulic, electromagnetic lege etc. can be operated.

In order to increase the interchangeability of the individual elements, one can, according to the Ausf ## tirun # -, sforin after 2ig. 3a and 3b summarize the bearing bodies of each group of bearing body pairs to form a unit. In this arrangement, the rollers 30a, j0b, 30e, 30d sit in groove-like inserts 31a, 31b, 31c and 31d, which extend outwards in an axial direction and are carried by rings 32a, J2b that enclose the column or the boom. The guide rollers can also be stored anIers, in particular the attachments can also be designed differently. These rings are located axially at a distance from one another and contain a cylindrical intermediate piece 33 between them, with a Detin or S,) irritant ring between the facing index of the intermediate piece and the ring, # 4 and the guide for the clamping piece can also be designed so that they can be used for adjustment during machining and assembly. Because of the adjustability of the guides can possibly be

the clamping of the column can be dispensed with.

The entire guide unit in the guide housing is protected from dust underneath, the free part with the help of a bellows, as shown in Fig. 3a is shown at 40, is sealed in an otaubeicher manner. Instead of a bellows you can one can also use a telescopic arrangement of rings etc.

In the modified embodiment of the subject matter of the invention according to Figs. For this purpose. 113 rings 41a, 41b of column 42 are each in an L -: gerungsring 4_7obzw. 43b rotatably mounted, which is seated on the guide tube 44 of the underframe. Ball bearings or wire ball bearings 45 are used for the rotatable mounting, the strips 46a, 48b are used for readjusting the mounting. The K Äemmwirkung is exerted in the arrow iiinne 47th In this case, the roller box is arranged on the column in such a way that it cannot be swiveled. As is not shown in the drawing, you can also store and guide the drilling quill like the column and the boom or the drilling carriage and also train them with a corresponding profile. Furthermore - as already indicated - of the drill feed caused by the upward and downward movement of the column and of the boom.

To simplify and rationalize, you can - as already indicated at the beginning - give the parts of the column or rotating casing and the boom participating in the tour the same cross-sectional shape; you can also - with the column moving up and down - the guides for the column and, its associated reciprocating boom or - with the boom that can be moved up and down and the drilling slide that moves back and forth - the guides for the boom that can be moved up and down

form the slide for the drill head in the same way. Here can e.g. also the Ciuschnittetormen of the column (or the rotating casing) and the Boom or the guides for the column and for the boom that can be moved back and forth or for the boom that can be moved up and down and for the slide for the drill head have the same dimensions.

Instead of a Spr.eitzringes one can, also a rubber-like ring made of plastic material., E.g. from the under the trade. use the plastic known as "neoprene", which expands when the face is pressed in, thereby clamping the guide housing,
