Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to an auxiliary support structure for CIPP pipeline repair. Background Art

[0002] The CIPP pipeline repair method has been widely used in the world since the 1980s for pipeline renovation in the fields of drainage, gas and petrochemicals. Its working principle is: a polymer coating is applied to the outer layer of a non-woven liner pipe, which is first impregnated with polyester resin or epoxy resin, and then flipped into the sewer or sewage pipe by water gravity or compressed air pressure. Once the liner is fully installed in the main pipeline, it is heated with water or steam to cause the resin to undergo a chemical reaction and solidify. After the liner is cured, a new structural pipeline will be formed in the original pipeline.

[0003] The utility model patent with the authorization announcement number CN205048071U discloses a CIPP pipeline repair auxiliary device, which includes a rod body, a cylinder, a clamp and a transverse rod. The transverse rod is an arc-shaped rod body whose shape is adapted to the inner wall of the pipeline, the transverse rod is fixed to the rod body, the clamp is fixed to the inner arc side of the transverse rod, and the cylinder is fixed to the outer arc side of the transverse rod. The clamp performs clamping / resetting movement under the push of the cylinder. The utility model has a simple structure and is easy to prepare. It avoids the problem of wrinkles in the airbag when passing through a 90° bend during the CIPP pipeline repair process, thereby generating a resin lining layer that is difficult to cut. The repair efficiency is improved and the difficulty of repair is reduced.

[0004] Although the above utility model can prevent wrinkles from forming inside the 90° bend pipe, when the repair device enters the pipe from the outside, the repair pipe entering the pipe from the outside has no external support at the pipe entrance, which may cause the repair device to bend and wrinkle. In view of this, we propose an auxiliary support structure for CIPP pipe repair. Utility Model Content

[0029] The auxiliary support structure for repairing a CIPP pipeline comprises a pipeline 1, a support mechanism 2 is fixedly installed on the upper side of the pipeline 1, and the support mechanism 2 comprises a fixing mechanism 21, two connecting cloths 22 fixedly installed on the upper surface of the fixing mechanism 21, a lower supporting sleeve 23 fixedly installed on the upper end of the connecting cloth 22, and an upper supporting sleeve 24 rotatably connected to the upper side of the lower supporting sleeve 23. Through the above mechanism, a repair device can be supported and guided by the support mechanism 2 before entering the pipeline 1, so as to prevent the repair device from bending and wrinkling before entering the pipeline 1.

[0030] Furthermore, the fixing mechanism 21 includes a left connecting sleeve 211 and a right connecting sleeve 212 arranged on the right side of the left connecting sleeve 211. The front and rear ends of the right side surface of the left connecting sleeve 211 are rotatably connected to a limiting screw 214. The limiting screw 214 is threadedly connected to a limiting nut 213, and the right connecting sleeve 212 is limited by the limiting nut 213.

[0031] Furthermore, a connection groove 231 is provided on the upper surface of the lower support sleeve 23, and the upper side edge of the inner surface of the lower support sleeve 23 is chamfered to prevent the repair device from being affected.
