Device for pulling in, and in particular curing, a pipeline liner

A device (10) for pulling, a pipeline lining (40) into/in a pipeline, comprising a housing (11) with a first end piece (12) and with a second opposite end piece (14), and a housing body (16) extending between the end pieces (12,14), and a power supply line which is connected to the first end piece (12), wherein an electromagnet (45) is provided on the second end piece (14), said electromagnet being coupled to the power supply line and being able to be energized via the latter, and wherein,

• the pipeline lining (40) is tubular and comprises a textile material, which is coated or impregnated with a resin, wherein the resin is curable, and the curing is undertaken by electromagnetic radiation of a specified wavelength or of a specified wavelength range, and wherein,
• the housing body (16) has radially extending arms (26), on the outer end faces of which at least one light-emitting diode (28) is arranged in each case, said light-emitting diodes emitting light of the specified wavelength or of the specified wavelength range, and being connected to the power supply line,
• the housing (10) has cooling-fluid passage openings (32) between the arms (26), which cooling-fluid passage openings are coupled to a cooling-fluid supply line and extend in the longitudinal direction at least in certain sections through the housing body (16),
• the cooling-fluid passage openings (32) are delimited radially outward by longitudinal webs (24) in the region of the housing body (16), and between the longitudinal webs (24) and the arms (26) and/or the light-emitting diodes (28) arranged on the arms (26), there is at least one gap-like outlet opening (34) which runs in the longitudinal direction and is intended for the cooling fluid.
