Description

The invention relates to an apparatus for inserting a pipeline lining into a pipe and for final positioning of the pipeline lining inserted in a pipe, wherein the apparatus comprises a housing, wherein a winding apparatus is formed in the housing and an attachment element is formed on a first housing opening, wherein either a cover plate or an inverter add-on is fastened to an at least second housing opening, according to claim 1. In addition, the invention relates to a method for inserting a pipeline lining in a pipe and for final positioning of the pipeline lining inserted in a pipe, wherein the apparatus according to the invention is used to carry out the method. It is known from the prior art to provide the interior of pipelines with a pipeline lining, which for example has an outer plastics layer and an inner fibre composite layer. Such pipeline linings have to be inserted here subsequently into pipes already laid, for example in the ground. Furthermore, it is often necessary that the pipeline linings already inserted have to be readjusted in respect of the actual position. It is known here for example to produce an ultimate or final position of the pipeline lining subsequently by means of calibration tubes. To this end it is necessary to use an apparatus with the aid of which the calibration tube can be inserted into an already laid pipeline lining portion. Multiple apparatuses are thus necessary in order to insert a pipeline lining into a pipe and then be able to position the pipeline lining correctly. An aim of the present invention is therefore to describe a further developed apparatus, wherein the aforementioned disadvantages are to be overcome. It is furthermore an aim of the invention to describe a further developed method for inserting and positioning a pipeline lining. The stated aims are addressed in accordance with the invention in respect of an apparatus for inserting a pipeline lining in a pipe and for final positioning of the pipeline lining inserted in a pipe by the article as per claim 1 and in respect of a method for inserting a pipeline lining into a pipe and for final positioning of the pipeline lining inserted in a pipe by the method according to claim 6. The dependent claims comprise at least expedient embodiments and developments. Specifically, the aim is addressed by an apparatus for inserting a pipeline lining into a pipe and for final positioning of the pipeline lining inserted in a pipe, wherein the apparatus comprises a housing, especially a drum-shaped housing, wherein a winding apparatus is formed in the housing and an attachment element, especially an attachment ring, is formed on a first housing opening. Either a cover plate or an inverter add-on is fastened to an at least second housing opening, wherein, in a first state for inserting the pipeline lining, the inverter add-on and, in a second state for final positioning of the pipeline lining, the cover plate is fastened to the second housing opening. According to the invention, an apparatus is thus provided with the aid of which both a pipeline lining can be inserted into a pipe and the already inserted pipeline lining can be arranged in its final position. The apparatus can thus be present at least in two states. A first state may be the state for inserting the pipeline lining. In this first state an inverter add-on is fastened to at least the second housing opening. A second state of the apparatus may be the state for final positioning of the pipeline lining. In this second state, the pipeline lining would already be located or inserted in the pipe. In the second state, a cover plate is fastened to the second housing opening. It is possible that the housing has further housing openings. However, at least two openings are formed, wherein an attachment element is formed on the first housing opening and the at least second housing opening is closed either with an inverter add-on or with a cover plate. It is possible that the apparatus is also present in a third state. Such a state may be a maintenance state or cleaning state. In such a state it is possible that the second housing opening is open or no further components are fastened to or mounted on the second housing opening. The housing preferably has a drum shape. The drum shape can be seen especially in a side view of the housing. This side view is such that the view is directed in the axial direction of the winding apparatus. By means of such a drum-shaped design of the housing it is possible to wind a tube, especially a calibration tube, on the winding apparatus, as is usual with the aid of a coiler. An attachment element is formed on the first housing opening. The attachment element may be a portion of the housing or a separate component. It is furthermore possible that the attachment element is formed both from a housing portion and a separately attached component. Both one end of the pipeline lining as well as one end of the calibration tube are guided from the f
