Description

Technical Field

[0001] This utility model relates to the technical field of oil pipe inspection equipment, specifically to an automatic identification device for oil pipe bending. Background Technology

[0002] Currently, during oilfield extraction, a large amount of oil sludge adheres to the inside and outside of oil pipes, requiring frequent cleaning and replacement. During use and transportation, oil pipes may bend. Existing oil pipe cleaning equipment typically cleans individual pipes. For example, an automatic oil pipe cleaning device disclosed in patent CN113351585A cannot clean severely bent pipes, and there is a risk of damaging the cleaning equipment. Therefore, it is necessary to select oil pipes that have minor bends and can be cleaned and reused, while those that cannot be used need to be cut and processed. Usually, oil pipe selection is done manually by workers, which is time-consuming, physically demanding, and carries the risk of injury. The selection efficiency is also low. Therefore, it is necessary to develop an automatic pipe bend identification device to reduce the workload of workers and improve selection efficiency. Utility Model Content

The anti-detachment frame is sloping and a baffle plate is provided at the end of the anti-detachment frame to prevent the oil pipes from slipping off.

[0009] Furthermore, the lifting mechanism includes a cylinder mounted on a platform, and a lifting plate is provided at the output end of the cylinder. The cylinder is controlled by a controller.

[0010] Furthermore, the number of lifting mechanisms is three, and the lifting plates include a first lifting plate, a second lifting plate, and a third lifting plate, which are placed in a staggered manner.

[0019] like Figure 1-3As shown, an automatic identification device for oil pipe bends includes a platform 2 for placing an oil pipe 1, the platform 2 being connected to a conveyor line 3 of an oil pipe cleaning device, a sensor mechanism 5 for detecting the oil pipe, and a fixed frame 4 slidably connected to the sensor mechanism. There are two sensor mechanisms 5, which operate synchronously on both sides during use to shorten the detection time. Each sensor mechanism 5 includes a laser sensor 501 and a fixing plate 502 for fixing the laser sensor 501. The fixing plate 502 is slidably connected to the fixed frame 4 via a linear guide rail. A wire rope groove is provided on the fixed frame 4, and a wire rope 503 is provided within the wire rope groove. The wire 504 of the laser sensor 501 is slidably connected to the wire rope 503 via several sliders 505. The device also includes a controller electrically connected to the sensor mechanism 5, which is a PLC.

[0020] like Figure 1 As shown, the frame 2 includes a loading waiting frame 201, an identification frame 202, and a bend placement frame 203. Several lifting mechanisms for conveying oil pipes are provided inside the frame 2. The loading waiting frame 201, the identification frame 202, and the bend placement frame 203 are inclined. At the ends of the loading waiting frame 201, the identification frame 202, and the bend placement frame 203, there are baffle plates 6 to prevent the oil pipes 1 from slipping. The height of the identification frame 202 is higher than the height of the loading waiting frame 201. On the outside of the conveyor line 3, there is an anti-detachment frame 204 for placing the oil pipes 1 that have fallen off the conveyor line 3. The anti-detachment frame 204 is inclined. At the end of the anti-detachment frame 204, there are baffle plates 6 to prevent the oil pipes 1 from slipping.

[0021] like Figure 1 As shown, the lifting mechanism includes a cylinder mounted on the platform 2. The cylinder output end is equipped with a lifting plate 7. The cylinder is controlled by a controller. The cylinder is not marked in the figure. A hydraulic cylinder or other telescopic components can also be used. There are three lifting mechanisms. The lifting plate 7 includes a first lifting plate 701, a second lifting plate 702, and a third lifting plate 703. The three lifting plates 7 are placed in a staggered manner. The lifting plates 7 are sloped. At the end of the lifting plate 7, there is an anti-detachment plate 704 to prevent the oil pipe 1 from slipping. The lifting plate 7 is staggered with the loading waiting rack 201, the identification rack 202, and the pipe bending rack 203. The three lifting plates 7 work together to transport the oil pipe 1 from the loading waiting rack 201 to the identification rack 202, from the identification rack 202 to the pipe bending rack 203, or to the conveyor line 3 of the oil pipe cleaning device.

[0022] When using, such as Figure 1As shown, the oil pipe 1 is placed on the loading waiting rack 201. The first lifting plate 701 rises, and the oil pipe 1 enters the inclined surface of the first lifting plate 701 from the loading waiting rack 201, automatically sliding down to the anti-detachment plate 701. The first lifting plate 701 continues to rise above the identification rack 202, and then the first lifting plate 701 falls, and the oil pipe 1 falls onto the identification rack 202, automatically sliding down to the baffle plate 6 of the identification rack 202. Two laser sensors 501 detect the oil pipe. If the oil pipe 1 is not bent... When the pipe 1 bends, the second lifting plate 702 rises to lift the oil pipe 1 and continues to fall to place the oil pipe 1 on the conveyor line 3. The bent oil pipe 1 is then transported into the oil pipe cleaning device. An anti-detachment frame 204 is set to prevent the oil pipe 1 from falling off the conveyor line 3 during transport. If the oil pipe 1 bends, the third lifting plate 703 rises to lift and lower the oil pipe 1, transporting the bent oil pipe to the bend placement frame 203. The PLC control device automatically completes the identification and transport, which greatly improves the identification efficiency and reduces the labor intensity of workers.
