Description

Technical Field

[0001] The present application relates to the technical field of pipeline repair, and in particular to a drainage pipeline repair device. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. Its structural components generally include main pipes, branch pipes and pipes leading to treatment plants. No matter whether they are built on the streets or anywhere else, as long as they are pipes that play a role in drainage, they should be counted as drainage pipes. Drainage pipes are made of a variety of materials, among which metal pipes are also very common. For example, galvanized iron pipes are the most commonly used material at present. Another example is welded steel pipes, which are mainly used to transport water, gas, air, oil, heating hot water or steam and other generally low-pressure fluids and other pipes. Another example is ductile iron pipes for water supply. Ductile iron pipes for water supply have the advantages of high strength, high toughness, good sealing performance, strong corrosion resistance, good durability, and convenient installation and construction. The disadvantage is that the pipes are heavy and difficult to install. The above pipes are all common metal pipes, which occupy a different weight in drainage pipes.

[0003] When existing metal drainage pipes are damaged and cracks or holes are formed, they are generally repaired by welding a metal sheet that is consistent with the material and can completely cover the damaged area as a repair sheet. This repair method is simple and easy, and is suitable for most metal pipe repair work. However, when repairing the pipe in this way, the worker needs to fix the repair sheet with his hand while welding, which requires the worker to operate with one hand during welding, which easily reduces work efficiency and work quality, or requires another worker to assist in fixing the repair sheet, which makes the repair operation more inconvenient. Therefore, in view of the above problems, a drainage pipe repair device is proposed. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present application provides a drainage pipe repair device, which fixes a fixing frame on the drainage pipe body 1 during welding repair, so that the part to be repaired is located between the first fixed end ring and the second fixed end ring, thereby achieving a fixed setting of the repair piece fixing structure at the part to be repaired, making it convenient to use a curved pressure plate to press and fix the metal repair piece, thereby freeing the hands of the staff and facilitating their welding work to be carried out efficiently and with high quality, overcoming the deficiencies in the prior art and aiming to solve the problem of welding inconvenience caused by the lack of efficient fixing measures for the repair piece during pipeline welding repair.

[0005] To achieve the above objectives, this application provides the following technical solutions:
