Description

METHOD AND DEVICE FOR ASSEMBLING, PARTICULARLY FOR LENGTHENING, A PIPE OR SYSTEM OF RODS}

In realizing a long length bore using a multi-part tube or drill rod assembly, the tube or rod assembly is generally in alignment with the tube or rod assembly already present in the bore with the aid of feeding or magazineing means. By positioning the member, it is known that the screwing of the existing tube or rod assembly member and this additional extension member is mostly by hand. Such feed or magazine means are disclosed, for example, in DE-A 198 43 167, EP-B 0 527 460 or EP-A 0 942 146. Such known supply and control means facilitate the operation, including the positioning of such elongate members with long lengths and thus relatively heavy weights, but nevertheless, these tubes can be relied on by suitable tools which are optionally manually operated. Alternatively, high work and time consumption is required due to the requirement of manually connecting rod assembly components. In addition, such work, such as providing an anchor bore or safety bore during the tunneling process, must be performed first in a partially unprotected area such as an excavation. Consideration should be given to safety hazards that threaten workers. Moreover, extremely narrow workspace conditions must be taken into account when such work is carried out, especially during tunneling.

The present invention relates to a method of assembling, in particular extending a tube or rod assembly, in particular a drill rod assembly, wherein it is to be connected to one another in order to obtain an extended length of the tube or rod assembly, In particular, each tube or rod assembly or jacket tube member to be screwed is connected to each other in terms of the actual alignment of said tube or rod assembly member and in the face of detachment of the actuation or introduction means. The invention also relates to a device for assembling, in particular extending, a tube or rod assembly, in particular a drill rod assembly, wherein the lifting and positioning means, in particular the pivotable lifting and positioning means, in particular the actuation of the tube or rod assembly And introduction means are arranged on support or retention means such as for example brackets provided to receive different tube or rod assembly members, respectively.

1 is a side view of an apparatus according to the invention for carrying out the method according to the invention for assembling, in particular extending, a tube or rod assembly.

FIG. 2 is a schematic partial enlarged view of FIG. 1, taken along line II-II, showing the lifting and positioning means of the device according to the invention according to FIG. 1.

3 is an enlarged, partial cross-sectional view of a region of a portion of the device according to the invention, including separate rotation means as well as clamping and centering means for the tube or rod assembly to be extended.

Departing from the foregoing prior art, it is an object of the present invention to provide an apparatus and method for assembling, in particular, extending a tube or rod assembly, in particular a drill rod assembly, which extends the rod assembly or jacket tube member by such an apparatus and method. Further automation of the process is possible. This automation is to ensure the reduction of the work and time required, as well as the simple operation of the extension of such tubes or rod assemblies.

In order to achieve the above object, a method of the kind mentioned at the outset is characterized by the fact that the connection or screwing of adjacent tube or rod assembly members is in contact with a tube or rod assembly member which respectively extends an existing tube or rod assembly. It is characterized in that it is automatically executed by means of rotation and / or actuation or introduction. Due to the fact that the present invention provides for the automatic connection or screwing of adjacent tube or rod assembly members or jacket tubes as well as the supply of tube or rod assemblies and extension members for jacket tubes with the aid of suitable feeding or magazine means. Or in connection or extension of the rod assembly or jacket tube, without any manual intervention. In the meantime, upon proper positioning and alignment of the tube or rod assembly member to be connected, the connection, in particular the screwing together, is actuated or introduced for the rod assembly member, for example when a rotary drive for rotary impact drilling is provided. A separate automatic means for the jacket tube member is used to achieve this directly and automatically by means and to automatically obtain the screwing integration and thus the extension of the jacket tube as well as the respective tube or rod assembly. The stability of the operator will therefore be increased, which will allow the operator to continue screwing these rod assemblies and jacket tubes together, especially when anchoring bores, for example in anchoring bores, in the first dug area, especially during underground work or tunneling. Because there is no need anymore. Moreover, the automated connection or screwing together reduces the overall work and time consumption, which, in addition to the automated supply and positioning of the elongate member, may be the connection or screwing of the tube or rod assembly or jacket tube to be extended, for example. This is because it is achieved directly by means of actuation or rotation arranged on the bracket. In particular, automation also eliminates errors in the direction of screwing or connection of adjacent members, which can optionally occur in manual operation. Such errors cannot be safely avoided or excluded, especially in manual screwing under limited space conditions. Monitoring of the direction of rotation of the rod assembly is particularly suitable because in the case of malfunctions which may optionally occur during the extension of the tube or rod assembly, there is a risk of loosening or detachment of the drill bit, in which case the piping is It must be removed and in some cases a new bore must be formed.

According to another preferred embodiment, the simplification and acceleration of the connection of the tube or rod assembly to be extended allows for the automatic centering of the tube or rod assembly member to be interconnected prior to connecting or screwing the tube or rod assembly, respectively.

When forming a bore, in particular when forming an anchor bore, in many cases it is suitable to enable continuous filling of the bore without fear of breakage of the surrounding material, and without partial disruption of the bore during the drilling process. In addition to the drill rod assembly in which the drilling tool is mounted, a bore is made by simultaneously introducing a jacket or cladding tube into the borehole. In this case, therefore, it is expected that not only the extension of the drill rod assembly but also the appropriate extension of such a jacket or cladding tube will be carried out, which jacket tube is designed to have each thin wall. In order to enable such a connection, which is usually centrally arranged to the drill rod assembly and the jacket tube surrounding the drill rod assembly as well as automated, when providing a drill rod assembly aligned inside the jacket tube according to another preferred embodiment It is proposed that the centering of the drill rod assembly within the jacket tube is carried out before connection or screwing, and that the drill rod assembly and the jacket tube are connected or screwed separately from the existing jacket tube or drill rod assembly member. This precentering of the drill rod assembly within the jacket tube during the supply of the unit, each consisting of an extension member for the drill rod assembly and an extension member for the jacket tube, results in the previous centering of the drill rod assembly in the jacket tube in the bore. Immediately assure accurate positioning of the individual members relative to already existing members, where separate connection or screwing together of the drill rod assembly and the jacket tube is carried out with the aid of separate or rotating means as well as automatic or introduction means. . In this specification, according to a preferred embodiment of the present invention, the drill rod assembly is connected, in particular screwed, in a first step using actuation or drilling means, and the jacket tube surrounding the drilling means is a separate rotating means. Are connected or screwed in the second step, respectively.

In order to solve the above object, the device of the kind defined at the outset is particularly characterized in that a separate rotating means is provided for connecting the adjacent jacket tube members. According to the invention, the automated connection of adjacent tube or rod assembly members is carried out directly by each rotary drive to the drill rod assembly, while a separate rotating means of suitable conventionally compact structure is provided for the extension of the jacket tube, This is because very large forces are not applied to connecting potentially thin walled jacket tubes, in particular to screwing.

During the connection process, in order to undoubtedly avoid any movement of the jacket tube and rod assembly already present in the bore, which can optionally cause problems or uncertainties with respect to the centering and / or complete connection or screwing of the elongate member. According to another embodiment of the invention, it is further provided that a clamping means for engaging the jacket tube or rod assembly to be connected is provided. During the positioning process such clamping means can be coupled in the tube or rod assembly or jacket tube to be extended, together with the lifting and positioning means to ensure a secure fixation of the jacket tube or rod assembly already present in the bore.

As already mentioned above, in many cases where boreholes are made, in particular during the next anchoring, rod assemblies are provided for making bores and for introducing drilling tools, as well as jackets or cladding tubes, have. In this regard, according to another preferred embodiment of the apparatus according to the invention, in order to extend the drill rod assembly and jacket tube which are usually arranged centrally, the jacket tube is provided when providing the drill rod assembly arranged inside the jacket tube. It is proposed that at least one further centering means is provided for centering the drill rod assembly within. In this case, the centering of the drill rod assembly in the jacket tube may preferably be simplified or facilitated by the provision of a centering means, in particular a pivotable centering means, on the lifting and positioning means.

If no actuating means are provided to enable rotational movement of the drilling tool during the formation of the bore, or the drill rod assembly and jacket tube surrounding the drill rod assembly are not connected with existing tubes and rod assemblies already in the bore. If not, as described above several times, a separate rotation means is provided. Another preferred practice of the invention, in low space conditions and to ensure particularly simple mounting of additional rotating means for extending the jacket tube, with or without affecting the actuation or introduction means to the rod assembly. According to an example, it is provided that a separate rotating means is fixed to a supporting or holding means, for example a supporting means separably separable relative to the bracket, and which can be coupled in the jacket tube member. By providing such separately fixable supporting means or devices to this kind of rotating means, it is also possible to further carry out retrofitting of existing retaining means, in particular brackets, so that existing drill brackets need not be newly constructed or reconfigured. However, it can be easily applied to an automated screwing or connecting process.

In order to clamp the tube or rod assembly to be extended, the present invention preferably proposes further centering and / or clamping means on the supporting means to secure the rod assembly or jacket tube to be extended. In order to further simplify the operation after completion of the extension during the drilling process and in particular to reduce the space requirements, according to another preferred embodiment the arrangement on the means for supporting the additional rotation means so that it can be displaced in the longitudinal direction of the jacket tube to be extended. It is proposed to be. It is here proposed in certain preferred embodiments that the driving means, in particular the cylinder piston unit, is provided on the means for supporting the rotation means so as to be displaceable.

In another preferred embodiment, in order to avoid proper movement between the elongate member and the tube or rod assembly to be extended, it is possible to make the appropriate positioning necessary for extending and centering the tube or rod assembly and possibly during the screwing process. It is proposed that the means be designed to include additional holding or anchoring means anchored or fixed in the material into which the jacket tube is introduced, particularly on the end that is remote from the bracket. Such holding or anchoring means, in particular during the creation of anchor bores in the area of the mineral face of the tunnel, for both the joining or extension process and the subsequent drilling process, reliable anchorage of both the support and the retaining means, in particular of the bracket. Is allowed.
