Description

Technical Field

[0001] This utility model belongs to the field of oil pumping unit technology, specifically a serrated wear-resistant oil pumping unit belt. Background Technology

[0002] Oil pumping units are mechanical devices that extract crude oil from oil wells and are widely used in the field of oil extraction. Their core function is to lift underground crude oil to the surface through mechanical movement.

[0003] Existing oil pumps inevitably use belts during operation. These belts are designed with a serrated shape, and their core feature is that the surface is designed with a serrated texture. Combined with wear-resistant materials and a special structure, this improves transmission efficiency, extends service life, and adapts to harsh working conditions. It can also effectively prevent slippage and ensure the stability of power transmission.

[0004] In current technology, these toothed belts, due to the pulley drive and the relatively long intervals between them, inevitably experience some degree of lateral deviation during transmission, leading to belt loosening, affecting the transmission effect, and compromising the overall stability of the operation.

[0005] Therefore, a serrated wear-resistant oil pumping unit belt is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the problem that due to the long intervals in the belt drive, the belt inevitably deviates to a certain extent during the transmission process, which leads to belt loosening, affects the transmission effect, and makes it impossible to guarantee the overall working stability, a sawtooth-shaped wear-resistant oil pumping unit belt is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A sawtooth-shaped wear-resistant pumping unit belt of this utility model includes a support base plate; a placement frame is fixedly connected to the top of the support base plate; an active rotating roller and two symmetrically arranged driven rotating rollers are rotatably connected to the inner side of the placement frame; a sawtooth belt is driven between the surfaces of the active rotating roller and the two driven rotating rollers; a bidirectional lead screw is rotatably connected between the inner sides of the placement frame; two symmetrically arranged limiting pressure plates are threaded to both ends of the bidirectional lead screw; a limiting support rod is fixedly connected to the inner side of the placement frame; and the surface of the limiting support rod is slidably connected to the inner side of the limiting pressure plate.

[0008] Preferably, the number of limiting struts is set to two, and the two limiting struts are symmetrically arranged on both sides of the bidirectional lead screw. The number of bidirectional lead screws is set to two, and the two bidirectional lead screws are symmetrically arranged on both sides of the placement frame.

[0009] Preferably, one end of the bidirectional lead screw passes through the placement frame and extends to one side of the placement frame, and an adjusting wheel is fixedly connected to the end of the bidirectional lead screw located on one side of the placement frame.

[0010] Preferably, a motor cylinder is fixedly connected to one side of the placement frame, and a built-in motor is fixedly connected inside the motor cylinder. A rotating shaft is fixedly connected to the center of the active rotating roller. One end of the rotating shaft passes through the placement frame and extends to one side of the placement frame. The output shaft of the built-in motor is fixedly connected to the end of the rotating shaft located on one side of the placement frame via a coupling.

[0011] Preferably, a connecting rod is fixedly connected to the center of the driven roller, both ends of the connecting rod pass through the placement frame and extend to both sides of the placement frame, and both ends of the connecting rod on both sides of the placement frame are fixedly connected to a transmission plug.

[0012] Preferably, a hydraulic rod is fixedly connected to the center of the top of the support base plate, a rotating retaining ring is fixedly connected to the top of the hydraulic rod, a rotating support rod is fixedly connected to the inner side of the rotating retaining ring, a pusher cylinder is rotatably connected to the surface of the rotating support rod and on both sides of the rotating retaining ring, a limiting groove adapted to the rotating support rod is opened on the surface of the placement frame, and the surfaces of both ends of the rotating support rod are slidably connected to the inner side of the limiting groove.

[0013] The beneficial effects of this utility model are: This utility model provides a serrated wear-resistant pumping unit belt. Through the cooperation design of the bidirectional lead screw and the limiting pressure plate, the tension of the serrated belt can be precisely adjusted according to the actual transmission requirements. When the belt shows signs of lateral deviation or looseness, the operator only needs to rotate the adjusting wheel to drive the bidirectional lead screw to rotate, which in turn drives the two limiting pressure plates to move towards or away from each other along the limiting support rod, so as to realize the synchronous adjustment of the tension on both sides of the belt, effectively correct the belt deviation phenomenon, and ensure the stability of the transmission process.

[0014] This utility model provides a serrated wear-resistant pumping unit belt. The combination structure of hydraulic rod and rotating support rod further enhances the belt's anti-lateral deviation ability. The hydraulic rod can extend and retract according to the working conditions, pushing the rotating support rod to slide in the limit slot, so that the pusher drum is always in close contact with the back of the serrated belt, providing continuous auxiliary support force, preventing the belt from excessive deformation under high-speed operation or heavy load conditions, thereby extending the belt's service life.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figure 1 - Figure 5This utility model provides a serrated wear-resistant pumping unit belt, including a support base plate 1; a placement frame 2 is fixedly connected to the top of the support base plate 1, and a driving roller 3 and two symmetrically arranged driven rollers 4 are rotatably connected to the inner side of the placement frame 2 respectively. A serrated belt 5 is driven between the surfaces of the driving roller 3 and the two driven rollers 4. A bidirectional lead screw 6 is rotatably connected between the inner sides of the placement frame 2, and two symmetrically arranged limiting pressure plates 7 are threaded to both ends of the bidirectional lead screw 6. A limiting support rod 8 is fixedly connected to the inner side of the placement frame 2, and the surface of the limiting support rod 8 is slidably connected to the inner side of the limiting pressure plate 7. During operation, the support base plate... 1 is used to support the placement frame 2. The driving roller 3 and the driven roller 4 rotate on the placement frame 2. The placement frame 2 supports the driving roller 3 and the driven roller 4. After the driving roller 3 rotates, it drives the sawtooth belt 5 to rotate, thereby driving the driven roller 4 to rotate. When adjustment is required, the bidirectional lead screw 6 rotates to drive the limiting pressure plate 7 to rotate. During this process, the limiting support rod 8 limits the limiting pressure plate 7 to ensure the normal adjustment of the limiting pressure plate 7. This allows the two limiting pressure plates 7 to move towards or away from each other along the limiting support rod 8, realizing the synchronous adjustment of the tension on both sides of the belt, effectively correcting the belt deviation phenomenon, and ensuring the stability of the transmission process.

[0019] Furthermore, such as Figure 3 and Figure 4 As shown, there are two limiting support rods 8, which are symmetrically arranged on both sides of the bidirectional lead screw 6. There are also two bidirectional lead screws 6, which are symmetrically arranged on both sides of the placement frame 2. One end of each bidirectional lead screw 6 passes through the placement frame 2 and extends to one side of the frame 2. An adjusting wheel 9 is fixedly connected to the end of the bidirectional lead screw 6 located on one side of the frame 2. During operation, one bidirectional lead screw 6 works in conjunction with two limiting support rods 8. Simultaneously, two bidirectional lead screws 6 are provided, allowing the bidirectional lead screw 6 to be adjusted while being limited and supported by the two limiting support rods 8. Furthermore, two bidirectional lead screws 6 are provided, both passing through the placement frame 2. The adjusting wheel 9 is fixedly installed at the end of each bidirectional lead screw 6 located on one side of the frame 2. The rotation of the adjusting wheel 9 drives the bidirectional lead screw 6 to rotate, thus achieving the adjustment function.

[0020] Furthermore, such as Figure 1 , Figure 2 and Figure 5As shown, a motor cylinder 10 is fixedly connected to one side of the placement rack 2, and an internal motor 11 is fixedly connected inside the motor cylinder 10. A rotating shaft 12 is fixedly connected to the center of the active rotating roller 3. One end of the rotating shaft 12 passes through the placement rack 2 and extends to one side of the placement rack 2. The output shaft of the internal motor 11 is fixedly connected to the end of the rotating shaft 12 located on one side of the placement rack 2 through a coupling. A connecting rod 13 is fixedly connected to the center of the driven rotating roller 4. Both ends of the connecting rod 13 pass through the placement rack 2 and extend to both sides of the placement rack 2. Both ends of the connecting rod 13 located on both sides of the placement rack 2 are fixedly connected to a transmission plug 14. During operation, a motor cylinder 10 is fixedly installed on one side of the placement frame 2. An internal motor 11 is fixedly installed inside the motor cylinder 10. After the internal motor 11 is working, it can drive the rotating shaft 12 to rotate through the output shaft, which in turn drives the active rotating roller 3 to rotate, thereby providing power for the transmission operation. A rotating rod 13 is fixedly connected to the center of the driven rotating roller 4. The two ends of the connecting rod 13 are used to fix and install the transmission plug 14. The transmission plug 14 is used to connect to external transmission components to complete the power transmission. The whole is designed with the transmission plug 14 of the driven rotating roller 4, which facilitates quick disassembly and maintenance, and improves the reliability and maintainability of the overall equipment.

[0021] Furthermore, such as Figure 3 and Figure 5 As shown, a hydraulic rod 15 is fixedly connected to the center of the top of the support base plate 1. A rotating retaining ring 16 is fixedly connected to the top of the hydraulic rod 15. A rotating support rod 17 is fixedly connected to the inner side of the rotating retaining ring 16. A pusher cylinder 18 is rotatably connected to the surface of the rotating support rod 17 and to both sides of the rotating retaining ring 16. A limiting groove 19 adapted to the rotating support rod 17 is opened on the surface of the placement frame 2. The surfaces of both ends of the rotating support rod 17 are slidably connected to the inner side of the limiting groove 19. During operation, a hydraulic rod 15 is fixed to the top of the support base plate 1. After the hydraulic rod 15 is in operation, it drives the rotating retaining ring 16 to rise and fall, thereby driving the rotating support rod 17 to rise and fall, and then driving the pushing drum 18 to rise and fall. This ensures that the pushing drum 18 can always be in contact with the surface of the sawtooth belt 5. The combination structure of the hydraulic rod 15 and the rotating support rod 17 further enhances the belt's anti-lateral deviation ability. The hydraulic rod 15 can extend and retract according to the working conditions, pushing the rotating support rod 17 to slide in the limiting groove 19, so that the pushing drum 18 is always in close contact with the back of the sawtooth belt 5, providing continuous auxiliary support force, preventing the belt from being excessively deformed under high-speed operation or heavy load conditions, thereby extending the belt's service life.

[0022] Working Principle: Due to the long intervals in belt pulley drives, the belt inevitably experiences some degree of lateral deviation during transmission, leading to belt loosening and affecting transmission efficiency, thus compromising overall operational stability. First, the support base plate 1 supports the placement frame 2. The driving roller 3 and driven roller 4 rotate on the placement frame 2, supported by the frame. The rotation of the driving roller 3 drives the toothed belt 5, which in turn drives the driven roller 4. When adjustment is needed, the bidirectional lead screw 6 rotates, causing the limiting pressure plate 7 to rotate. During this process, the limiting support rod 8 limits the movement of the limiting pressure plate 7, ensuring its normal adjustment. This allows the two limiting pressure plates 7 to move towards or away from each other along the limiting support rod 8, achieving synchronous adjustment of the belt tension on both sides, effectively correcting belt deviation and ensuring transmission stability. In this process, a bidirectional lead screw 6 is used in conjunction with two limiting support rods 8, and two bidirectional lead screws 6 are also set up. This allows the bidirectional lead screw 6 to be adjusted while being limited and supported by the two limiting support rods 8. In addition, two bidirectional lead screws 6 are set up, both of which pass through the placement frame 2. One end of the bidirectional lead screw 6 located on one side of the placement frame 2 is used to fix and install the adjusting wheel 9. The rotation of the adjusting wheel 9 drives the bidirectional lead screw 6 to rotate, thereby achieving the adjustment function. In addition, a motor cylinder 10 is fixedly installed on one side of the placement frame 2. An internal motor 11 is fixedly installed inside the motor cylinder 10. After the internal motor 11 is working, it can drive the rotating shaft 12 to rotate through the output shaft, which in turn drives the active rotating roller 3 to rotate, thereby supplying power for the transmission operation. A rotating rod 13 is fixedly connected to the center of the driven rotating roller 4. The two ends of the connecting rotating rod 13 are used to fix and install the transmission plug 14. The transmission plug 14 is used to connect to external transmission components to complete the power transmission. The entire design of the driven rotating roller 4 and the transmission plug 14 facilitates quick disassembly and maintenance, improving the overall reliability and maintainability of the equipment. Finally, a hydraulic rod 15 is fixed to the top of the support base plate 1. After the hydraulic rod 15 is working, it drives the rotating retaining ring 16 to rise and fall, thereby driving the rotating support rod 17 to rise and fall, and then driving the pushing drum 18 to rise and fall. This allows the pushing drum 18 to always be in contact with the surface of the sawtooth belt 5. Here, the combination structure of the hydraulic rod 15 and the rotating support rod 17 further enhances the belt's anti-lateral deviation ability. The hydraulic rod 15 can extend and retract according to the working conditions, pushing the rotating support rod 17 to slide in the limiting groove 19, so that the pushing drum 18 is always in close contact with the back of the sawtooth belt 5, providing continuous auxiliary support force, preventing the belt from being excessively deformed under high-speed operation or heavy load conditions, thereby extending the belt's service life.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
