Description

Technical Field

[0001] The utility model relates to the technical field of oil exploitation, in particular to an oil pumping unit in an oil exploitation well. Background Art

[0002] The oil pump is a kind of mechanical equipment for oil extraction, commonly known as "bowing machine". The oil pump is the most important lifting equipment in the rod pumping system.

[0003] The prior art oil pumps occupy a large area during operation and take up a large amount of surrounding space during installation, which makes it difficult to install more oil pumps within a limited space. Therefore, an oil pump for oil wells is proposed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide an oil pumping unit for oil production underground, which has the advantages of small footprint and can be installed more in a limited space, thus solving the problem of large land occupation by existing oil pumping units.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil pumping unit for oil well production, comprising a base frame, a support frame is fixedly installed on the rear end of the upper surface of the base frame, a mounting hole is opened on the front end of the upper surface of the base frame, a positioning frame is fixedly installed on the upper surface of the base frame outside the mounting hole, a sliding rod is slidably installed on the top of the positioning frame, and also includes a rack;

[0006] The rack is fixedly installed at the bottom of the slide bar;

[0007] Wherein, gears are meshed and installed on both sides of the rack;

[0008] Among them, a distance sensor is fixedly installed on the sliding rod above the rack;

[0009] Wherein, a touch rod matching the distance sensor is installed on the positioning frame above the distance sensor.

[0010] When using an oil pumping unit in an oil well in the technical solution, the base frame is fixedly installed on the ground at the top of the oil well to ensure its stability. A positioning frame is fixed on the outer side of the front end of the base frame to support and position the sliding rod. The sliding rod is slidably installed on the positioning frame, and a rack is fixedly installed at the bottom thereof. Gears are meshed and installed on both sides of the rack. A driving mechanism is installed on the top of the support frame to connect with the gear transmission. The driving mechanism can rotate forward and reverse to control the rotation direction of the gear. A sucker rod is fixedly installed at the bottom of the rack through a connecting rope. The sucker rod passes through a limiting ring and extends into the oil well. The outer diameter of the sucker rod matches the inner diameter of the limiting ring to ensure that the sucker rod can pass smoothly and perform the oil pumping operation. The sensor is installed above the slide bar and is electrically connected to the drive mechanism to monitor the position and movement of the sucker rod. The front end of the gear is rotated to install a limit frame, and the bottom end of the limit frame is fixedly connected to the upper surface of the base frame to ensure the stable movement of the gear. When in use, start the drive mechanism and select forward or reverse rotation as needed. The drive mechanism drives the rack to move through the gear, thereby driving the sucker rod to move up and down in the oil well. The sucker rod moves up and down in the oil well to perform the pumping operation. The distance sensor monitors the position of the sucker rod in real time to ensure that it works within a safe range. The operator monitors the working status of the sucker rod based on the data fed back by the sensor and adjusts the working parameters of the drive mechanism as needed to optimize the pumping efficiency. Regularly inspect and maintain the various components of the pumping unit to ensure the normal operation of the equipment and extend its service life.

[0011] Preferably, the base frame is fixedly mounted on the ground at the top of the oil production well, and the mounting hole is located directly above the oil production well.

[0012] The base frame is fixedly installed on the ground at the top of the oil well, ensuring the stability of the entire pumping unit.

[0013] The installation hole is located directly above the oil well, ensuring that the sucker rod can be accurately aligned with the center of the oil well, thereby improving the pumping efficiency.

[0014] Preferably, a limiting ring is embedded and installed in the installation hole, and both upper and lower ends of the limiting ring are designed with inclined surface structures and are recessed inwards.

[0015] The limit ring is embedded in the mounting hole, and its inclined surface structure is designed to be concave inward, which can effectively limit the position of the sucker rod and prevent it from deviating from the center line. At the same time, the inclined surface design helps to guide the sucker rod to enter the oil well smoothly.

[0016] Preferably, a driving mechanism is fixedly installed on the top of the support frame, the driving mechanism is installed in a transmission manner with two gears, and the driving mechanism can rotate forward and reverse.

[0017] The driving mechanism is installed on the top of the support frame and is connected to the gear transmission, and can be rotated forward and reversely, which provides operational flexibility and can adjust the movement direction of the sucker rod as needed.

[0018] Preferably, a sucker rod is fixedly mounted on the bottom of the rack via a connecting rope, and the sucker rod passes through a limiting ring and extends into the oil well.

[0019] The rack is connected to the sucker rod through a connecting rope, so that the movement of the sucker rod is driven by the rotation of the gear. This design simplifies the mechanical structure and improves the transmission efficiency.

[0020] Preferably, the outer diameter of the sucker rod matches the inner diameter of the limiting ring.

[0021] The outer diameter of the sucker rod matches the inner diameter of the limit ring, which ensures smooth movement of the sucker rod during the pumping process and reduces friction and wear.

[0022] Preferably, the distance sensor is electrically connected to the driving mechanism.

[0023] The distance sensor is electrically connected to the drive mechanism and can monitor the position and movement status of the sucker rod in real time, providing accurate feedback information to the operator, which helps to achieve automated control and improve safety.

[0024] Preferably, a limiting frame is rotatably mounted on the front ends of the two gears, and the bottom end of the limiting frame is fixedly connected to the upper surface of the base frame.

[0025] The front end of the gear is rotatably mounted on a limit frame, and the bottom end of the gear is fixedly connected to the upper surface of the base frame, thereby enhancing the structural stability of the entire oil pumping unit and preventing displacement or deformation during the oil pumping process.

[0026] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0027] The utility model arranges a rack, which is fixedly installed at the bottom of the sliding rod, and gears are respectively meshed and installed on both sides of the rack, a distance sensor is fixedly installed on the sliding rod above the rack, and a touch rod matching the distance sensor is installed on the positioning frame above the distance sensor, a support frame is fixedly installed at the rear end of the upper surface of the base frame, and a mounting hole is opened at the front end. This design of the front and rear end layout can maximize the use of the space of the base frame and reduce unnecessary floor space. The sliding rod is slidably installed on the top of the positioning frame. This design allows the oil pump to be compactly folded or contracted in the vertical direction, thereby occupying less space when not working. The sucker rod is vertically extended into the oil production well through a limit ring. This vertical design helps to reduce the floor space in the horizontal direction, and at the same time allows the sucker rod to directly act on the well, thereby improving the oil pumping efficiency. The rack, gear, sliding rod and distance sensor The modular design of components such as sensors allows them to be compactly assembled together, reducing the overall size and facilitating installation and adjustment in limited space. The distance sensor can accurately control the position of the sucker rod, reducing the additional space occupied by improper operation, while improving the safety and efficiency of the operation. The feeler rod on the positioning frame matches the distance sensor. This precise positioning mechanism can ensure that the pumping unit components are accurately positioned in a limited space and avoid unnecessary waste of space. The meshing transmission design of the gear and rack makes the movement of the sucker rod more precise and efficient, reducing the space occupied by the complex transmission system. Due to the modular and compact design of the components, maintenance and expansion when necessary become easier, without the need for large-scale space adjustments to the entire system, achieving the effect of occupying a small area and being able to install more in a limited space.
