Description

Technical Field

[0002] Currently, most onshore oil fields use beam pumping units, with belt drives being the primary method of ground power transmission. These wells are often operated in the field, are highly dispersed, and experience high load variations, making maintenance challenging. After replacing a new belt on a pumping unit, the new belt quickly stretches and loosens, causing the belt to slip and lose rotation, reducing production efficiency. Belt changes require four to five adjustments during production, each taking approximately 30 minutes, directly impacting crude oil production. Furthermore, belt slippage increases energy consumption, accelerates belt wear, shortens belt life, and increases production costs. Addressing these issues is urgent. Summary of the Invention

[0030] Installation and use

[0031] The existing pumping unit base is removed, and the intelligent mobile base for automatic belt tensioning of this embodiment is installed on the main beam of the pumping unit. The pumping unit motor 81 is installed on pumping unit motor mounting base 1 3 and pumping unit motor mounting base 2 12. The motor 6 is installed on pumping unit motor mounting base 1 3. The pressure range of the tension pressure sensor 11 is set in the electrical control box. Press the forward button, and the motor 6 drives the reducer 7 to start operation. The lead screw 71 of the reducer 7 pushes the pumping unit motor mounting base 1 3 and the pumping unit motor mounting base 2 12 to slide on the circular shaft of the slide rail 1 2 and the slide rail 2 20. When the tension pressure sensor 11 reaches the set value, the motor 6 stops, and the pumping unit belt reaches the optimal tension state. The pumping unit belt will wear and become loose after long-term operation. At this time, the pressure value of the tension pressure sensor 11 is less than the set pressure range, and the motor 6 starts to work and continues to tighten the belt. When the pressure value of the tension pressure sensor 11 reaches the set value range, the motor 6 stops, and the belt always operates at the optimal tension state. When the belt reaches the end of its service life and breaks, the tension sensor 11 falls below the set value, and the motor 6 starts operating. Pumping unit motor mounting bracket 1 3 and pumping unit motor mounting bracket 2 12 slide on the cylindrical axis of slide rails 1 2 and 20 in the tensioning direction. When limit switch 2 18 strikes limit switch limit post 2 19, the motor 6 stops operating. The provision of limit switches ensures equipment safety.

[0032] When replacing the belt, switch the control box to manual mode and press the back button on the electric control box. The motor 6 starts working, and the pumping unit motor mounting seat 1 3 and the pumping unit motor mounting seat 2 12 slide on the circular tube axis of the slide rail 1 2 and the slide rail 2 20 in the opposite direction of the belt tensioning. When the travel switch 1 8 hits the travel switch limit column 1 9, the motor 6 stops working. After replacing the belt, switch the knob of the electric control box to the automatic gear position and press the tightening button. The belt will automatically tighten.

[0033] The fixed connection described in the above embodiments is welding or bolt connection.
