Definitions

the invention relates to a clamping device for clamping a fixing block on a tubular article.
Fixierblöcke are usually designed as flexible components with variable radius of curvature in order to achieve a radius adjustment of the fixing block to the given radius of the tubular member can.
the fixing blocks are essentially formed as plastic components, which can be welded by means of Bankwarelsch spatechnik on plastic pipes and the like on the outer circumference.
To enable the radius adjustment of the fixing block to the outer peripheral radius of the tubular article and to press the fixing block for welding to the outer circumference of the tubular article is it is known to open the fixing block by means of tension straps on the tubular article.
tensioning device is, for example, from Plasson Ltd. sold under the name "Flex Restraint".
Fixierblöcke be used in pipe relining as a fixed bearing for fixing the pipe ends and prevention of pipe shrinkage in the retracted line. Since the drawn-in pipe ends are partly installed in very hard to reach places, an encompassing belt solution can not be used. The fixation of the blocks must then transfer the clamping pressure to the pipe surface via a radial gripping clamping device. It is therefore an object of the invention to provide a tensioning device of the type described above, which does not have the disadvantages of the devices known from the prior art and in particular is easy to handle.
the independent claim 8 relates to a corresponding arrangement of a tensioning device, a tubular article and a fixing block.
the independent claim 10 relates to a corresponding method for mounting a fixing block on a tubular article.
the dependent claims relate to advantageous embodiments of the invention.
the tensioning device has a tensioning bow with a radius of curvature which is variable in relation to a pretension and at opposite longitudinal ends in each case a tool receptacle for a tensioning tool. It is thereby achieved that, by clamping the tensioning bow over its opposite longitudinal ends, the radius of curvature of the tensioning bow can be adapted to a radius of curvature of a tubular object onto which the fixing block is to be clamped.
an arc length in the longitudinal direction of the clamping arc is adjustable by at least one of the tool holders for a clamping tool in the longitudinal direction of the clamping arc is displaceable.
the at least one displaceable tool holder can be fixable in different adjustment positions in the longitudinal direction.
the tool holder can be connected via a guided in a slot fastening means with the tension bow.
the slot can have either the tension bow or the tool holder.
both tool holders are designed to be displaceable in the longitudinal direction of the tensioning bow.
the invention describes an arrangement of a clamping device according to one of the preceding claims, a tubular article and a fixing block, wherein the fixing block on the tensioning device and with the aid of a Clamping tool, which acts on the opposite tool holders, is clamped on the outer circumference of the tubular article.
Clamping device 100 shown essentially consists of a clamping arc 110, at its opposite longitudinal ends 120 each have a tool holder 130 for a clamping tool (not shown) is arranged.
the tool holders 130 are displaceable in the longitudinal direction of the tensioning bow 110 in order to be able to adapt the length L of the tensioning bow 110 and thus the tensioning device 100 to different diameters of the tubular object.
the tool holders 130 have undercut grooves 131, such as for the arrangement of the An horrtellers a screw clamp or the like, which is to serve as a clamping tool.
the tensioning device 100 is formed as a substantially elongate component whose tensioning bow 110 has a strip-shaped or plate-shaped element 111. At half the length L of the tensioning device 100, a fixing 114 is formed, with which the tensioning bow 110 can be fastened on the fixing block via its side 112 facing the fixing block (not shown).
the tensioning bow 110 or the plate-shaped element 111 has a slot 114 in which a fastening means 115, for example a screw, is displaceable in the longitudinal direction of the tensioning bow 110 in order to realize the length adjustment of the tensioning bow 110 already described above.
a fastening means 115 for example a screw
FIGS 3-5 show an application example of a clamping device 100 according to the invention, in which three clamping tools 400 are provided in order to clamp a fixing block 200 on a tubular article 300 with the aid of the clamping device 100.
a further, optional clamping tool 400 is provided, which acts on half the length of the clamping arc 110 in order to achieve an additional contact pressure in the central region of the fixing block 200.
the clamping tools 400 may be formed as a screw clamps, which are placed on a pipe end 320 in the illustrated arrangement of the tubular article 300, the fixing block 200 and the clamping device 100.
the clamping tools 400 are supported on an inner periphery 330 of the tube 300, while they attack with their screw-adjustable Anpressteller on the tool holders 130 and on the clamping arc 110.
the fixing block 200 has a support side 230, via which it is placed on the tubular article 300, and radially extending ribs 220 thereof, whose free ends form the support surface for the tensioning bow 110 of the tensioning device 100.
the clamping tools 400 are formed with a handle for manual operation. Instead of the handle can also be provided that the clamping tools 400 has a compact structural coupling for a tool.
the clamping tools may have an external hexagon.
FIG. 6 shows a further embodiment of the clamping device 100 according to the invention, which is shown for better illustration without clamping tools.
the clamping device 100 essentially consists of a clamping arc 110, at the longitudinal ends 120 of which a tool holder 130 is arranged in each case for one clamping tool.
a pressing device 500 is provided, which is placed centrally between the two end tool holders 130 on the tensioning bow 110.
the pressing device 500 essentially consists of a pressure plate 510, which is placed on height-adjustment elements 520 on the tensioning bow 110.
