Description

Technical Field

[0001] The invention relates to the technical field of oil production, and in particular to an oil pipe slideway device used for automatic oil well repair. Background Art

[0002] Oil is a fluid mineral buried deep underground. In 1982, the world's oil production was 2.644 billion tons and natural gas was 158.29 billion cubic meters. In the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well and then rise from the bottom of the well to the wellhead. Oil is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature oil, the combustible gas natural gas, and the solid combustible oil mineral asphalt. With the in-depth study of these minerals, it is realized that they are all hydrocarbon compounds in composition and are related to each other in origin, so they are collectively called oil. Oil is an important energy source. Compared with coal, it has the advantages of high energy density (the heat of combustion of the same weight of oil is 50% higher than that of standard coal), convenient transportation and storage, and less pollution to the atmosphere after combustion. Fuel oil extracted from oil is the main fuel for transportation vehicles, power plant boilers, metallurgical industry and various kilns in the building materials industry. Liquefied gas and pipeline gas made from oil are high-quality fuels used in urban residents. Aircraft, tanks, ships, rockets and other spacecraft also consume a lot of petroleum fuel. Therefore, many countries have listed petroleum as a strategic material. Petroleum is a fluid mineral buried deep underground. Initially, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid flammable oil minerals asphalt. With the in-depth study of these minerals, it is realized that they are all hydrocarbon compounds in composition and are related to each other in origin, so they are collectively called petroleum. Petroleum is a complex mixture of gaseous, liquid and solid hydrocarbon compounds existing in nature and a small amount of impurities. Therefore, petroleum extraction also includes natural gas extraction.

[0003] In the process of oil extraction, well repair operations are an important part of ensuring the continued efficient operation of oil wells. In traditional well repair operations, the transportation of oil pipelines often relies on manual operations, which is not only inefficient but also poses certain safety risks.

[0004] Therefore, we propose an oil pipe slide device for oil well automation repair. Summary of the invention

[0005] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides an oil pipe slideway device for automatic well repair of petroleum.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an oil pipe slideway device for automated oil well repair, comprising a mounting frame, an inner wall of the mounting frame is provided with an oil pipe conveying mechanism, the oil pipe conveying mechanism comprises a mounting block, and the back side of the mounting block is fixedly connected to the rear end of the inner wall of the mounting frame, a first mounting rod is fixedly installed at the lower end of the front side of the mounting block, a second mounting rod is fixedly installed on the right side of the front side of the mounting block, a lifting limit rod is movably installed on the inner wall of the mounting block, a limiting ring is fixedly installed at the bottom of the lifting limit rod, and a limiting slide groove is fixedly installed on the top of the lifting limit rod, a servo motor is provided on the front side of the first mounting rod, and the front side of the servo motor is fixedly connected to the front end of the inner wall of the mounting frame.

[0007] Preferably, the output end of the servo motor movably penetrates the back side of the first mounting rod and is fixedly mounted with an eccentric wheel, and the outer wall of the eccentric wheel is movably connected to the inner wall of the limiting ring.

[0008] Preferably, a first connecting rod is fixedly mounted on the middle end of the back side of the eccentric wheel.

[0009] Preferably, a rotating connecting rod is movably mounted on the front upper end of the first connecting rod via a rotating shaft.

[0010] Preferably, the front middle end of the rotating connecting rod is movably connected to the inner wall of the second mounting rod through a rotating shaft.

[0011] Preferably, a second connecting rod is movably mounted on the front upper end of the rotating connecting rod via a rotating shaft.

[0012] Preferably, a limiting slider is movably installed on the left side of the outer wall of the second connecting rod via a rotating shaft.

[0013] Preferably, the lower end of the outer wall of the limiting sliding block is movably connected to the inner wall of the limiting sliding groove.

[0014] Preferably, a conveying push head is fixedly mounted on the left side wall of the limiting sliding block.

[0015] The present invention provides an oil pipe slideway device for automated well repair in petroleum, which has the following beneficial effects:

[0016] 1. This oil pipe slideway device for automated oil well repair realizes the automation of oil pipe transportation by setting up an oil pipe transportation mechanism. When the servo motor is started, it will drive the eccentric wheel to rotate. Since the eccentric wheel is movably connected to the limit ring, the rotation of the eccentric wheel will drive the limit ring to move up and down, thereby driving the lifting limit rod to move up and down in the mounting block. This design cleverly utilizes the rotational motion of the eccentric wheel to convert it into linear motion, providing a power source for oil pipe transportation. At the same time, the first connecting rod is connected to the rotating connecting rod through a rotating shaft, and the rotating connecting rod is movably connected to the inner wall of the second mounting rod through a rotating shaft, forming a four-bar linkage. When the eccentric wheel rotates, it will drive the first connecting rod to move up and down, and then drive the second connecting rod to move left and right through the rotating connecting rod. The design of this four-bar linkage makes power transmission more stable and can achieve precise control of the direction of oil pipeline transportation. In addition, a limit slider is installed on the left side of the second connecting rod through a rotating shaft, and the lower end of the limit slider is movably connected to the inner wall of the limit slide groove, which ensures the stable movement of the limit slider in the horizontal direction, and the fixed delivery push head on the left side of the limit slider is directly used to push the oil pipeline along the slide. This design not only simplifies the structure of the oil pipeline transportation mechanism, but also improves the stability and efficiency of oil pipeline transportation. Through ingenious mechanism design, the automation, stabilization and efficiency of oil pipeline transportation are realized. In the process of oil production, it can significantly improve the efficiency of well repair operations, reduce the risk of manual operation, and provide a strong guarantee for the smooth progress of oil production.

[0017] 2. This oil pipe slide device used for automated oil well repair realizes automated transportation of the oil pipe, reduces the chance of direct manual contact with the oil pipe, and thus reduces the risk of accidents caused by improper operation or fatigue. At the same time, the internal mechanism of the device is reasonably designed, and the connections between the components are firm, ensuring the stability and safety of the equipment during long-term operation.

[0018] 3. This oil pipe slide device used for automated oil well repair adopts easily disassembled structures such as rotating shafts and slideways through the connection between various components, which is convenient for rapid maintenance and replacement when a fault occurs. In addition, the overall structure of the device is compact, occupies a small area, and is also convenient for daily cleaning and maintenance.

[0019] 4. This oil pipe slide device used for automated oil well repair can flexibly control the speed and force of oil pipe transportation by adjusting parameters such as the speed of the servo motor and the eccentricity of the eccentric wheel to meet the transportation needs of oil pipes of different specifications and materials. At the same time, the design of the slide also takes into account the size and shape of the wellhead of the oil well, ensuring that the oil pipe can smoothly enter the wellhead.

[0020] 5. Compared with the traditional manual transportation method, the oil pipe slide device used for automated oil well repair reduces the manpower and energy consumption during the transportation process, and also reduces the waste of resources caused by improper human operation. In addition, since the device runs smoothly and has low noise, it also reduces the noise pollution to the surrounding environment. BRIEF DESCRIPTION OF THE DRAWINGS
