Description

Technical Field

[0001] This utility model relates to the field of oil and gas pipeline cleaning, and in particular to a special tool for removing balls and cleaning up dirt in oil and gas pipeline cleaning operations. Background Technology

[0002] Oil and gas pipelines are the main arteries for transporting oil and gas. During their operation, solid impurities such as water, silt, and rust in the transported medium accumulate in low-lying areas of the pipeline, and these deposits accumulate over time. Contaminants in natural gas pipelines not only affect the quality of the natural gas and the accuracy of downstream flow meters, but can also form hydrates that clog the pipeline, especially at low temperatures. The hydrogen sulfide content in crude oil reacts chemically with water and other substances accumulated in the pipeline, causing severe corrosion and increasing the risks to pipeline operation. The work of removing cleaning balls and cleaning up oil sludge during pipeline cleaning is quite demanding; therefore, developing a convenient, practical, and efficient specialized tool for this purpose is crucial.

[0003] For example, Chinese utility model patent application CN 218692291 U discloses a pig-grabbing tool and a pipeline cleaning device. The pig-grabbing tool includes a cylinder and a piston mechanism. The cylinder is hollow, with an adsorption element at its first end for adsorbing the pig. The piston mechanism is inserted into the cylinder from its second end and can slide along the cylinder in a sealed manner. This solution reliably grips heavy and oily pigs, but the device structure is relatively complex and inconvenient to use.

[0004] Furthermore, the pig collection process during pipeline cleaning mainly involves two steps: first, scraping out the oil residue from the collection drum, and then removing the pig. Existing technologies generally only address tools for removing the pig, not tools for cleaning the oil residue and sludge from the collection drum. Therefore, developing a convenient tool that can both clean the oil residue from the collection drum and remove the pig would not only be easy to use but also effectively improve work efficiency. Utility Model Content

[0005] In order to solve the problems existing in the prior art, this utility model provides a special tool for cleaning and removing debris in oil and gas pipeline cleaning operations.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a special tool for cleaning and removing debris from oil and gas pipelines, comprising an operating rod, a hook, a telescopic support assembly, and an explosion-proof scraper; the head end of the operating rod is provided with a first connecting thread, and the operating rod is connected to the hook or the explosion-proof scraper through the first connecting thread; the telescopic support assembly is provided on the operating rod to support the operating rod.

[0007] This invention is mainly used in the process of collecting and cleaning oil and gas pipelines during pipeline cleaning operations. The operating rod is connected to an explosion-proof scraper, which is used to clean the oil and sludge inside the collecting cylinder. After cleaning, a hook is attached to the top of the operating rod, and the height of the telescopic support assembly is adjusted according to the diameter of the oil and gas pipeline. The hook is then inserted into the oil and gas pipeline to hook the hanging ring of the pipeline cleaning device, and the pipeline cleaning device is pulled out of the pipeline.

[0008] The present invention is further configured such that the telescopic support assembly is provided in two sets, namely a first telescopic support assembly and a second telescopic support assembly; The first telescopic support assembly and the second telescopic support assembly each include a first telescopic rod, a second telescopic rod, and a support wheel; one end of the first telescopic rod is connected to a connecting ring, and the other end is threadedly connected to the second telescopic rod, and the support wheel is provided at the bottom of the second telescopic rod; the two sets of telescopic support assemblies are connected to the operating rod through the connecting ring.

[0009] The extension lengths of the first and second telescopic rods can be adjusted by rotating them forward or backward.

[0010] The purpose of the above structure is to provide support for the operating rod through the telescopic support assembly, while also being telescopic to accommodate ball receiving tubes of different diameters.

[0011] The present invention is further configured such that the first telescopic support assembly, the second telescopic support assembly, and the ground form a triangular support state, thereby increasing the stability of the operating rod.

[0012] The present invention is further configured such that the telescopic support assembly also includes a bearing, which is sleeved between the connecting ring and the operating rod.

[0013] The purpose of the above structure is to allow the operating lever to rotate freely by setting bearings, so that the hook at the top can easily hook the lifting ring of the pig.

[0014] The present invention is further provided with support wheels at the bottom of the first telescopic rod and the second telescopic rod, respectively.

[0015] The purpose of the above structure is to facilitate the movement of specialized tools for cleaning and removing contaminants along the oil pipeline during pipeline cleaning operations, using support wheels.

[0016] The present invention is further configured such that the special tool for cleaning and removing debris in oil and gas pipeline cleaning operations also includes several extension rods; the tail end of the operating rod is provided with a second connecting thread, which is used to connect the operating rod and the extension rod.

[0017] The present invention is further configured such that the explosion-proof scraper is made of copper.

[0018] To use the tool described in this invention to clean pipelines, the pig needs to be inserted into the launching tube. Under the pressure inside the pipeline, the pig pushes the contaminants in the pipeline towards the end of the pipeline. After cleaning, the pig finally enters the collecting tube and is removed through the collecting tube. Alternatively, the operating rod is first connected to an explosion-proof scraper, which is used to clean the oil stains inside the collecting tube. After cleaning, a hook is attached to the top of the operating rod. The height of the telescopic support assembly is adjusted according to the diameter of the collecting tube. The hook is then inserted into the collecting tube to hook the hanging ring of the pig, and the pig is pulled out of the oil pipe.

[0019] Compared with the prior art, the beneficial effects of this utility model are specifically reflected in: The tool of this invention is applicable to the removal of the pig from the pig collection cylinder and the cleaning of sludge oil during oil and gas pipeline cleaning operations.

[0020] 1. This utility model is simple to operate, with replaceable hooks or explosion-proof scrapers on the head, enabling quick and accurate completion of pig retrieval and cleaning in oil and gas pipeline cleaning operations, improving work efficiency and reducing operation time and costs. The overall structure is freely disassembled and can be reused after cleaning, making it suitable for cleaning and removing pigs from the pig retrieval cylinder in fire- and explosion-proof oil and gas locations.

[0021] 2. This utility model uses explosion-proof materials, which can ensure the safety of operators and avoid accidents caused by tool failure or improper operation.

[0022] 3. This utility model is equipped with an adjustable height telescopic support component, which is suitable for oil and gas pipelines of different specifications and materials, and has strong versatility and applicability. Attached Figure Description
