Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a winch inner liner pipe docking mechanism for pipeline repair. Background Art

[0002] UV-curing lining repair technology is one of the trenchless on-site curing lining repair methods for drainage pipes. A fiberglass hose soaked in light-curing resin is dragged into the cleaned pipe to be repaired using a winch. The hose is connected to an air duct to supply air inward and inflate it to make it fit tightly against the inner wall of the pipe. Professional UV light emission and control equipment is used to irradiate the inner wall of the pipe to cure the resin inside the pipe, forming a new high-strength lining pipe.

[0003] In the prior art, when docking the inner liner pipe with a winch, a steel wire rope is usually inserted into the interior of the pipe, and then the inner liner pipe is tied with the steel wire rope. Subsequently, the steel wire rope is pulled by the winch to move, and the steel wire rope is used to drive the inner liner pipe to move inside the pipe to be repaired. This docking method can easily cause damage to the connection of the inner liner pipe. Since the contact area between the steel wire rope and the inner liner pipe is small and the pressure is large, the inner liner pipe will be more worn at the position where it is tied with the steel wire rope after being subjected to a large tensile force. In addition, the bundling and subsequent disassembly operations are inconvenient, time-consuming and labor-intensive. In view of the shortcomings of the prior art, the utility model provides a winch inner liner pipe docking mechanism for pipeline repair to solve the above problems. Utility Model Content

The rotating screw drives the clamping positioning plate to move and clamp the liner pipe. The carrier frame and the liner pipe clamping assembly arranged at the top and bottom of the carrier frame are used, so that the liner pipe can be conveniently double-extruded and fixed at the interface position when docking with the winch output end. The interface has good stability, the liner pipe has a large force-bearing area, the force is stable, and it is not easy to be damaged during the pulling of the liner pipe.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] The embodiment of the present application solves the problem that the connection between the wire rope at the output end of the winch and the liner pipe is easily damaged by docking in the prior art by providing a winch liner pipe docking mechanism for pipeline repair. Since the contact area between the wire rope and the liner pipe is small and the pressure is strong, the wear of the liner pipe at the binding position with the wire rope increases after being subjected to a large tensile force, and the bundling and subsequent disassembly operations are inconvenient, time-consuming and labor-intensive.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The utility model discloses a winch inner liner pipe docking mechanism for pipeline repair. Figure 1-3 As shown, it includes a docking bracket 1 and a winch wire rope 2 fixedly connected between the docking bracket 1 and the output end of the winch. The bottom of the docking bracket 1 is provided with a universal wheel 101. The design of the universal wheel 101 makes the entire docking bracket 1 easy to move, with low friction with the ground, and convenient for transferring the inner liner pipe. The interior of the docking bracket 1 is fixedly connected to a carrier frame 3;

[0024] The top and bottom of the carrier 3 are both provided with an inner liner pipe clamping assembly, which includes an inner liner pipe clamping seat 4, which is fixedly connected to the carrier 3;

[0025] A slot 401 is provided on the inner liner tube clamping seat 4, a screw rod 402 is threadedly connected to the inner liner tube clamping seat 4, a rotating handle 407 is provided on the screw rod 402, and a notch 102 corresponding to the rotating handle 407 is provided on the docking bracket 1. The notch 102 and the rotating handle 407 are designed to facilitate the rotation of the screw rod 402;

[0026] A clamping positioning plate 403 is rotatably connected to the screw rod 402, and the clamping positioning plate 403 is slidably connected to the inside of the inner liner pipe clamping seat 4. The device adopts a supporting frame 3 and an inner liner pipe clamping assembly arranged on the top and bottom of the supporting frame 3, so that when the inner liner pipe is docked with the output end of the winch, the interface position is double-extruded and fixed, the interface has good stability, the force-bearing area of ​​the inner liner pipe is large, the force is stable, and it is not easy to be damaged during the pulling process of the inner liner pipe.

[0027] When using the inner liner tube clamping assembly to clamp and limit the inner liner tube, first pass the inner liner tube through the inner liner tube clamping seat 4 at the bottom and top of the support frame 3 in turn, and pass through and out of the clamping groove 401, and then rotate the screw rod 402 in turn so that the screw rod 402 drives the clamping positioning plate 403 to move and clamp the inner liner tube. The two groups of inner liner tube clamping seats 4 and the clamping positioning plate 403 form a double clamping and clamping positioning. A rubber pad 406 is fixedly connected to the clamping positioning plate 403. The design of the rubber pad 406 makes the clamping stable, the friction at the clamping position large, and the wear small.

[0028] A lateral support column 404 is fixedly connected to the clamping positioning plate 403, and a lateral support sleeve 405 is fixedly connected to the inner liner pipe clamping seat 4. The lateral support column 404 is slidably connected in the lateral support sleeve 405. When the screw rod 402 rotates to drive the clamping positioning plate 403 to move, the clamping positioning plate 403 synchronously drives the lateral support column 404 to move along the lateral support sleeve 405, so that the clamping positioning plate 403 is laterally supported and the force is stable.
