Description

Technical Field

[0001] This invention belongs to the technical field of pipeline maintenance equipment, specifically relating to a pipeline repair clamp and its pipeline repair method. Background Technology

[0002] In traditional construction work, pipeline installations are often susceptible to damage from subsequent construction such as decoration and renovation. When repairing damaged pipelines, the usual method is to cut off the damaged section and then use a larger pipe of the same material as a connector for double-ended heat fusion to repair the damaged area. Construction workers need to perform measurement, cutting, and heat fusion operations. If a suitable size pipe is not available, it must be purchased again, which is time-consuming, labor-intensive, and material-intensive. Because pipe heat fusion machines have high power and require electricity, they cannot be used for field operations, which greatly increases maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide a pipeline repair clamp and a pipeline repair method, which overcomes the time-consuming and labor-intensive drawbacks of existing pipe repair and construction processes, while reducing material consumption and improving construction efficiency.

[0004] To achieve the above objectives, the technical solution used in this invention is: The pipeline repair clamp includes: two clamp components assembled into a circular tube shape, each clamp component having a magnet and self-locking teeth inside, and an arc-shaped plate on the inner wall of the clamp component; the self-locking teeth include two interlocking outer and inner racks, with multiple teeth on the inner surface of the outer rack and multiple teeth on the outer surface of the inner rack; the clamp component has an arc-shaped channel, with the outer and inner racks respectively installed in the arc-shaped channels of the two clamp components.

[0005] Furthermore, after the ends of the two pipe clamps are closed, the outer and inner toothed racks mesh with each other, connecting the two pipe clamps together.

[0006] Furthermore, the self-locking teeth are shaped like arc strips, made of stainless steel, with multiple arc strips parallel to each other and set inside the arc channel.

[0007] Furthermore, the outer wall of the outer rack is connected to the outer wall of the arc-shaped channel, and the inner wall of the inner rack is connected to the inner wall of the arc-shaped channel.

[0008] Furthermore, the outer layer of the pipe clamp assembly is made of polypropylene, and the inner layer is made of random copolymer polypropylene; the arc-shaped piece is made of stainless steel, and the outer side of the arc-shaped piece is embedded in the inner wall of the pipe clamp assembly.

[0009] Furthermore, the magnet is shaped like an arc plate, with multiple arc plates parallel to each other, and is set inside the pipe clamp section.

[0010] Furthermore, the magnet is shaped like a strip plate, with two strip plates set on the two end faces of the two pipe clamps.

[0011] Furthermore, the magnet and the arc-shaped piece are semi-circular rings, and the tube clamp is shaped like a semi-circular plate.

[0012] Pipeline repair methods include: When the pipeline is damaged, fasten the two pipe clamps together at the point of damage, insert the outer and inner toothed racks into the arc-shaped channels of the pipe clamps respectively, and use the attraction of the magnets to initially assemble the two pipe clamps, so that the outer and inner toothed racks can mesh and connect with each other. The two pipe clamps are squeezed together, and the arc-shaped plate on the inner wall of the pipe clamp cuts into the pipeline to seal the damaged point.

[0013] Preferably, the arc-shaped plate cuts into the pipeline to a depth of about 0.5 mm, sealing the damaged point without damaging the pipeline's strength and preventing the leakage of liquid or gas from inside the pipeline.

[0014] The technical effects of this invention include: This invention is applicable to the repair tools for various synthetic resin pipes, overcoming the drawbacks of time-consuming and labor-intensive pipe repair construction processes in the prior art. At the same time, it reduces the use of consumables, significantly reduces labor costs, improves construction efficiency, and effectively controls the overall budget cost and waste of consumables.

[0015] Using pipe repair clamps to repair damaged pipelines can not only overcome the drawbacks of existing construction techniques, but also effectively reduce maintenance costs and improve construction efficiency.

[0016] When exposed pipelines are damaged and the main valve cannot be found, the magnetic attraction of the pipeline repair clamp can be used to directly repair the damaged parts. Attached Figure Description

Figure 3 The diagram shown is a schematic diagram of the self-locking locking teeth in this invention.

[0022] Pipeline repair clamps include: two clamp parts 1, which are combined to form a circular pipe component. Each clamp part 1 has a magnet 2 and a self-locking tooth 3 inside, and an arc-shaped piece 4 on the inner wall of the clamp part 1.

[0023] In this preferred embodiment, the outer layer of the pipe clamp 1 is made of polypropylene (PP), and the inner layer is made of random copolymer polypropylene (PPR); the arc-shaped piece 4 is made of stainless steel, with its outer side embedded in the pipe clamp 1 and its inner side designed with a blade to facilitate cutting the damaged outer wall of the pipeline.

[0024] In this preferred embodiment, the magnet 2 is shaped like an arc-shaped plate or a strip-shaped plate. Multiple arc-shaped plates are parallel to each other and are disposed inside the clamp body 1. Two strip-shaped plates are disposed on the two end faces of the two clamp bodies 1.

[0025] The self-locking tooth 3 includes two interlocking outer toothed racks 31 and inner toothed racks 32. The inner surface of the outer toothed rack 31 is provided with multiple locking teeth, and the outer surface of the inner toothed rack 32 is provided with multiple locking teeth. The pipe clamp assembly 1 is provided with an arc-shaped channel, and the outer toothed rack 31 and inner toothed rack 32 are respectively installed within the arc-shaped channel of the two pipe clamp assemblies 1. After the ends of the two pipe clamp assemblies 1 are closed, the outer toothed rack 31 and inner toothed rack 32 interlock and connect to each other, linking the two pipe clamp assemblies 1 together.

[0026] In this preferred embodiment, the self-locking teeth 3 are arc-shaped strips made of stainless steel. Multiple arc-shaped strips are parallel to each other and arranged within the arc-shaped channel of the clamp body 1. The outer wall of the outer toothed rack 31 is connected to the outer wall of the arc-shaped channel, and the inner wall of the inner toothed rack 32 is connected to the inner wall of the arc-shaped channel.

[0027] In this preferred embodiment, the magnet 2 and the arc-shaped piece 4 are semi-circular rings, which can better adapt to the semi-circular plate shape of the pipe clamp part 1.

[0028] The pipeline repair method and specific steps are as follows: Step 1: When the pipeline is damaged and leaks water or gas, fasten the two pipe clamp parts 1 at the damaged point, insert the outer toothed rack 31 and the inner toothed rack 32 into the arc-shaped channel of the pipe clamp part 1 respectively, and use the attraction of the magnet 2 to initially assemble the two pipe clamp parts 1. Step 2: Squeeze the two pipe clamp parts 1 to make the outer toothed rack 31 and the inner toothed rack 32 mesh with each other, and the arc-shaped piece 4 on the inner wall of the pipe clamp part 1 cuts into the pipeline to seal the damaged point.

[0029] The arc-shaped piece 4 cuts into the pipeline to a depth of about 0.5mm, sealing the damaged point without damaging the pipeline's strength, thus preventing the leakage of liquid or gas from inside the pipeline.

[0030] The pipeline repair method is designed for repairing existing damaged pipelines. It overcomes the slightly cumbersome traditional process by using pipeline repair clamps for leak sealing, which can greatly reduce repair time, improve work efficiency, simplify procedures, and quickly respond to sudden pipeline damage. It not only reduces labor costs and material waste, but is also durable and robust.

[0031] The terminology used in this invention is descriptive and exemplary, not restrictive. Since this invention can be embodied in many forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
