Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to a bottom membrane fixing device 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. The fiberglass hose soaked in light-curing resin is dragged into the cleaned pipe to be repaired by a winch, and the air duct is connected to the inside to blow it up so that it is close to the inner wall of the pipe. The inner wall of the pipe is irradiated with professional UV light emission and control equipment to cure the resin inside the pipe, forming a high-strength new lining pipe. When the repair hose is dragged in, a base film needs to be laid in the pipe in advance. The function of the base film is to protect the outer wall of the liner and reduce the friction of the liner entering the main pipe.

This fixing method is relatively cumbersome, the contact area between the bolts and the base membrane is small, and it is easy to cause damage to the base membrane. In the subsequent process of pulling the fiberglass hose, the base membrane may be torn. In view of the shortcomings of the prior art, the utility model provides a base membrane fixing device for pipeline repair to solve the above problems. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The embodiment of the present application provides a bottom membrane fixing device for pipeline repair, which solves the problem that the bottom membrane needs to be fixed in position after it is laid. The traditional fixing method mainly uses expansion bolts driven into the ground for fixing. This fixing method is relatively cumbersome, the contact area between the bolts and the bottom membrane is small, and it is easy to cause damage to the bottom membrane. In the subsequent process of pulling the fiberglass hose, the bottom membrane may be torn.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model discloses a bottom membrane fixing device for pipeline repair. Figure 1-4 As shown, it comprises an anchor rod 1 set on the ground, a positioning nut 101 is threadedly connected to the anchor rod 1, a fixing seat 2 is movably clamped on the anchor rod 1, and the fixing seat 2 is fixed between the positioning nut 101 and the ground;

[0025] A screw rod 3 is threadedly connected to the fixing seat 2, and a pressing seat 4 is rotatably connected to the bottom of the screw rod 3, and the pressing seat 4 is slidably connected to the inside of the fixing seat 2;

[0026] The base film is clamped between the pressing seat 4 and the fixing seat 2 .

[0027] Furthermore, a positioning block 201 which is sleeved on the anchor rod 1 is fixedly connected to the fixing seat 2. The positioning block 201 is clamped with the anchor rod 1 and is clamped and fixed by the positioning nut 101, so that the position of the fixing seat 2 is conveniently fixed.

[0028] A slide groove 202 is provided on the fixed seat 2, and a slider 401 is fixedly connected to the pressing seat 4. The slider 401 is slidably connected in the slide groove 202. The cooperation between the slider 401 and the slide groove 202 provides lateral support for the pressing seat 4, so that the force on the pressing seat 4 is stable.

[0029] Furthermore, a limiting hole 203 is opened on the fixed seat 2, and a lateral support rod 402 is fixedly connected to the clamping seat 4, and the lateral support rod 402 is slidably connected in the limiting hole 203. The set lateral support rod 402 and the limiting hole 203 provide secondary lateral support for the clamping seat 4, so that the force of the clamping seat 4 is stable and the clamping effect on the bottom film is good.

[0030] The screw rod 3 is provided with a rotating handle 301 , and the rotating handle 301 makes the screw rod 3 easy and labor-saving to rotate.

[0031] Furthermore, a rubber pad 5 is fixedly connected to the bottom of the clamping seat 4, and an anti-slip groove 501 is provided at the bottom of the rubber pad 5. The set rubber pad 5 can further ensure that the clamping seat 4 has good stability when clamping and fixing the bottom membrane, and the bottom membrane is not easy to loosen or fall off, thereby ensuring the good quality of the pipeline repair operation.

[0032] The bottom membrane fixing device for pipeline repair can directly use the ground anchoring device near the manhole to achieve rapid fixing when fixing the bottom membrane. During operation, the fixing seat 2 is first clamped and fixed with the anchor rod 1 of the ground anchoring device. After fixing, the bottom membrane is passed between the clamping seat 4 and the fixing seat 2. After passing through, the screw rod 3 is rotated so that the screw rod 3 pushes the clamping seat 4 to move, and the clamping seat 4 is used to achieve rapid clamping of the bottom membrane, thereby achieving rapid fixation of the position of the bottom membrane.

[0033] The device has a compact overall structure and is easy to use. When fixing the bottom film, it can be quickly fixed. The contact area between the clamping seat 4 and the bottom film is large, which has a good effect on fixing the position of the bottom film. It is also convenient to remove and reuse the fixing device later to meet usage requirements.
