Description

Technical Field

[0001] The utility model relates to rust removal of petroleum pipelines, in particular to a rust removal device for installing petroleum pipelines. Background Art

[0002] Oil pipelines are usually made of metal, and metal surfaces are susceptible to oxidation corrosion and rust when exposed to air, water vapor and other environmental factors for a long time. Rust removal can remove these rust stains and protect the material of the pipeline from further damage; the pipeline joint is the weak link of the entire pipeline system. If there is rust on the joint, it will affect the tightness and stability of the connection and may even cause leakage. Rust removal can ensure that the metal surface of the joint is clean and smooth, thereby improving the reliability of the connection. Therefore, oil pipelines need to be rust-removed when they are installed and connected.

[0003] In the oil industry, the installation and connection of pipelines are crucial links. However, since oil pipelines are usually made of metal, they are exposed to complex and changing environments for a long time, and the surface of metal pipelines is easily oxidized and corroded, resulting in rust. These rusts not only affect the aesthetics of the pipeline, but more importantly, they may have a serious impact on the connection quality and service life of the pipeline.

[0004] Traditional rust removal methods often rely on manual operation, which is not only inefficient, but also difficult to ensure the uniformity and thoroughness of rust removal. In addition, manual rust removal also has certain safety hazards and may cause physical harm to operators.

[0005] Therefore, there is an urgent need for a better rust removal device for oil pipeline installation on the market. Utility Model Content

[0048] Structure Description:

[0049] The device is mainly composed of a middle fixed frame mechanism 100 and a rust removal and grinding machine 300.

[0050] Middle fixed frame mechanism 100:

[0051] The main body is a U-shaped core frame 101, whose shape clearly presents a U-shaped structure when viewed from a top view.

[0052] In order to enhance the stability of the frame, the two wing ends of the core frame 101 are tightly combined with the side panels 102 by threaded connection. These side panels 102 form a bridge between the two ends of the U-shaped frame, providing necessary support and rigidity for the entire frame.

[0053] A guide groove 103 is carefully designed on the inner side of the back of the core frame 101. This groove completely runs through the back of the frame, providing a basis for subsequent adjustment functions.

[0054] The core frame 101 is fixedly provided with a nut 104, which is matched with a hand screw 105. This bolt is designed to pass through the back of the frame and go deep into the guide groove body 103 to achieve subsequent fixing and adjustment functions.

[0055] Rust removal grinding machine 300:

[0056] The main body 301 of the rust removal and grinding machine 300 is firmly placed in the middle fixed frame mechanism 100 to ensure that it has sufficient stability and support during use.

[0057] The main body 301 is equipped with a long friction strip 303, and its design direction is consistent with the overall direction of the rust removal grinder 300. This long friction strip 303 is cleverly designed to pass through the guide groove 103 of the core frame, so that its position can be accurately fixed by adjusting the hand screw 105.

[0058] The working part of the rust removal grinding machine 300, i.e. the rust removal grinding wheel part 302, is cleverly placed between the running wheels 202 of the two side frame bodies 201. This layout is not only easy to operate, but also can ensure stability and accuracy during the rust removal grinding process.

[0059] Directions:

[0060] Placement device:

[0061] The device is placed as a whole at the opening of the oil pipeline to be processed, and the running wheels 202 on the two side frames 201 are ensured to stably contact the outer wall of the pipeline, so as to provide a stable support for the device and ensure smooth movement during the grinding process.

[0062] Adjust the grinding machine position:

[0063] According to the diameter of the pipeline and the position to be polished, the position of the rust removal grinder 300 in the middle fixed frame mechanism 100 is adjusted. By loosening or tightening the hand bolt 105, the rust removal grinder 300 can be moved along the guide groove body 103 until the rust removal grinding wheel part 302 is closely attached to the outer wall of the oil pipeline.

[0064] Start the grinder:

[0065] After confirming that the rust removal grinding wheel portion 302 is closely attached to the outer wall of the pipeline, the rust removal grinding machine 300 is started. At this time, the rust removal grinding wheel portion 302 will start to rotate, and the outer wall of the oil pipeline is rust removed.

[0066] Flexible adjustment:

[0067] If it is necessary to adapt to different diameters of oil pipelines or adjust the depth of grinding, it can be conveniently achieved by screwing the hand screw bolt 105. After loosening the bolt, move the rust removal grinder 300 to a new position along the guide groove 103, and then tighten the bolt again to fix the position of the grinder. This design enables the device to flexibly adapt to pipelines of various diameters and different grinding requirements.

[0068] Operation Notes:

[0069] During operation, the operator should be kept away from the grinding area to prevent injury caused by splashing rust or debris. At the same time, the wear of the rust removal grinding wheel 302 should be checked regularly, and the seriously worn parts should be replaced in time to ensure the grinding effect and operation safety.

[0070] Wide adaptability: The device can adapt to oil pipelines of different diameters. This is due to the adjustable design between the middle fixed frame mechanism 100 and the rust removal grinder 300. By tightening the hand bolt 105 and the guide groove body 103, the position of the rust removal grinder 300 can be easily adjusted to adapt to pipelines of various diameters. This wide adaptability enables the device to perform excellently in different scenarios.

[0071] Flexible and reliable adjustment: The device allows stable and reliable adjustment according to actual use, such as the degree of grinding. The operator can precisely control the position of the rust removal grinder 300 by turning the hand screw 105 as needed, thereby achieving different degrees of grinding effect. This flexibility enables the device to meet various complex rust removal needs.

[0072] Easy operation: This device is easy to use. The placement, adjustment and startup steps are designed to be intuitive and easy to understand, and can be operated without complex training or professional skills. This simplicity greatly improves work efficiency and reduces the difficulty of operation.

[0073] Excellent stability: The device has good stability, which can ensure the accuracy and efficiency of the rust removal operation. The solid design of the central fixed frame mechanism 100 and the stable support of the running wheels 202 provide a good stability foundation for the entire device. During the rust removal process, the device can maintain a stable operating state to avoid vibration or deviation affecting the grinding effect. This stability not only improves the work quality, but also extends the service life of the equipment.

[0074] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
