Description

Technical Field

[0001] This utility model relates to the field of oil pumping unit suspension rope tension testing technology, and in particular to an oil pumping unit suspension rope tension testing device. Background Technology

[0002] In the oil extraction industry, pumping units are one of the key pieces of equipment ensuring crude oil production. The pumping unit suspension rope, as a crucial component supporting the weight of the sucker rod string and downhole equipment, directly affects the safe and stable operation of the pumping unit. Therefore, a pumping unit suspension rope tensile testing device has become an important testing tool to ensure the reliability of the suspension rope's quality. By conducting tensile tests on the suspension rope using this device, key performance indicators such as strength and toughness can be obtained, providing data support for the safe use of the pumping unit. With the continuous development of the oil extraction industry, the performance requirements for pumping unit suspension ropes are becoming increasingly stringent, and correspondingly, more stringent standards are being placed on the accuracy, safety, and reliability of the tensile testing device.

[0003] Currently, existing pumping unit suspension rope tension testing devices typically consist of a loading system, a measuring system, and a fixing device. The loading system often uses hydraulic methods, applying tension to the suspension rope via hydraulic jacks. The measuring system mainly relies on force sensors and displacement sensors to monitor the stress and deformation of the suspension rope under tension in real time. The fixing device securely mounts the suspension rope to the testing device, ensuring it does not slip during the test. The technical principle is to use the loading system to simulate the stress state of the suspension rope in actual operation, and to collect relevant data through the measuring system to evaluate the rope's performance. The entire experimental process aims to realistically reproduce the working conditions of the suspension rope in the pumping unit, thereby accurately determining whether the rope meets the usage requirements.

[0004] However, existing pumping unit suspension rope tension testing devices have a significant safety hazard. During the suspension rope tension test, due to the enormous tension exerted on the rope, if the rope or clamps accidentally detach or break due to quality issues or reaching their limits, the high-speed ejected parts act like dangerous projectiles, causing serious bodily injury to nearby personnel and even endangering their lives. They can also damage surrounding instruments and equipment. Furthermore, during the test, personnel may inadvertently approach the rope and equipment undergoing the tension test due to negligence or improper operation, facing the risk of being struck or entangled by moving parts. Existing testing devices lack comprehensive protective measures, failing to effectively prevent detached or broken parts from detaching, and are inadequate in isolating and protecting personnel, thus failing to provide reliable safety for personnel and surrounding property. This seriously affects the safety and normal conduct of the experiment. Therefore, a new pumping unit suspension rope tension testing device is proposed to address these problems. Utility Model Content

[0036] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Reference Figures 1-4This utility model provides an embodiment of a pumping unit suspension rope tensile testing device, comprising a main body 1. Existing pumping unit suspension rope tensile testing devices consist of a main body 1, a base 2, a hydraulic jack 3, a clamp 22, a force sensor, a displacement sensor, and other components. These devices are used to test the tensile strength of the pumping unit suspension rope, transmitting data to a computer and using dedicated testing software. If the rope does not break, the strength meets the standard; if it breaks, the strength does not meet the standard. This is existing technology and will not be elaborated further here. The main body 1 has a protective component on its outer wall. The base 2 is fixedly connected to the bottom of the main body 1. The hydraulic jack 3 is slidably connected to the inner wall of the main body 1. The clamp 22 is installed inside the main body 1, and the outer wall of the clamp 22 has a quick-release mechanism. The protective components include a protective frame 4 and a protective plate 9. The outer wall of the protective frame 4 is located on one side of the main body 1 of the experimental device, and the outer wall of the protective plate 9 is fixedly connected to the other side of the main body 1 of the experimental device. A slot 8 is provided on the outer wall of the main body 1 of the experimental device. A protective net 5 is fixedly connected inside the protective frame 4. The protective net 5 is made of high-strength steel wire mesh with fine and uniform mesh, which can effectively block the flying rope fragments and broken parts during the test. A handle 6 is fixedly connected to the outer wall of the protective frame 4, which allows the operator to easily move the protective frame 4. An L-shaped block 7 is fixedly connected to the outer wall of the protective frame 4. The L-shaped block 7 engages with the slot 8. This engaging structure is ingeniously designed. The protective frame 4 can be quickly installed and disassembled by pulling the handle 6 up or down. The operation is simple and convenient and the connection is stable and reliable.

[0038] Reference Figure 1 and Figures 5-8The quick-release assembly includes two T-shaped sliders 10. One T-shaped slider 10 is fixedly connected to the inner wall of the main body 1 of the experimental device, and the other T-shaped slider 10 is fixedly connected to the outer wall of the hydraulic jack 3. A clamp 22 is slidably connected to the outer wall of each T-shaped slider 10. A limiting hole 23 is provided on the outer wall of the clamp 22. A limiting plate 11 is fixedly connected to the outer wall of the T-shaped slider 10, which limits the sliding range of the clamp 22 and allows for faster positioning during clamp installation. A fixing plate 12 is also fixedly connected to the outer wall of the T-shaped slider 10. A fixing plate 19 is fixedly connected to the outer wall of the T-shaped slider 10. The fixing plate 19 is used to prevent the fixed rod 18 from shifting during installation, thus avoiding the inability to limit the clamp 22 due to the shift of the fixed rod 18. A rotating rod 13 is fixedly connected to the inner wall of the fixing plate 12. A pull rod 14 is rotatably connected to the outer wall of the rotating rod 13. The function of the pull rod 14 is to drive the fixed rod 18 by rotating the rotating rod 13 in a circular motion on the outer wall of the fixing plate 12. A rotating rod 15 is rotatably connected to the inner wall of the pull rod 14. The rotating rod 15... To drive the connecting arm 16 to move, a rotating rod 17 is rotatably connected to the inner wall of the other end of the connecting arm 16. The rotating rod 17 is used to connect the connecting arm 16 and the fixed rod 18. The outer wall of the fixed rod 18 is slidably connected to the inner wall of the fixed plate 19. A fixed plate 20 is fixedly connected to the outer wall of the fixed rod 18. A spring 21 is sleeved on the outer wall of the fixed rod 18. One end of the spring 21 is fixedly connected to the outer wall of the fixed plate 19, and the other end of the spring 21 is fixedly connected to the outer wall of the fixed plate 20. The spring 21's rebound limits the fixed rod 18 within the limiting hole 23. To prevent the clamp 22 from shaking during the experiment, the outer wall of the fixing rod 18 is slidably connected to the inner wall of the limiting hole 23. When the clamp 22 needs to be installed, pull the pull rod 14 to remove the fixing rod 18 from the limiting hole 23. After the clamp 22 is slid into place along the T-shaped slider 10, release the pull rod 14. Under the action of the spring 21, the fixing rod 18 automatically inserts into the limiting hole 23, realizing the quick fixation of the clamp 22. When disassembling, repeat the above operation to easily remove the clamp 22. The whole process is simple and quick, greatly improving the experimental efficiency.

[0039] Working principle: During the pumping unit hoisting rope tension test, first push the L-shaped block 7 into the slot 8, then press down the handle 6 to fix the protective frame 4. When the hoisting rope breaks, the protective net 5 and the protective plate 9 can intercept the hoisting rope and metal fragments that may fly everywhere after the rope breaks, preventing these objects from flying directly to the staff or surrounding equipment, thereby reducing the risk of personnel injury and equipment damage. When it is necessary to remove the protective frame 4, simply pull the handle 6 upwards and then pull the handle 6 outwards to release the fixation of the protective frame 4.

[0040] When it is necessary to replace clamp 22, firstly, by pulling the pull rod 14, the rotating rod 13 rotates in a circular motion on the outer wall of the fixed plate 12. Then, by pulling the pull rod 14, the rotating rod 15 moves. The movement of the rotating rod 15 then moves the connecting arm 16. The movement of the connecting arm 16 then moves the rotating rod 17. Immediately afterward, the movement of the rotating rod 17 moves the fixed rod 18. The movement of the fixed rod 18 then moves the fixed plate 20. Finally, the movement of the fixed plate 20 moves the spring 21. The compression causes the fixing rod 18 to move out of the limiting hole 23, releasing the clamp 22 from its limitation. Then, simply pull the clamp 22 to remove it. When installing the required clamp 22, simply slide the clamp 22 on the outer wall of the T-shaped slider 10. Then, when the outer wall of the clamp 22 contacts the limiting plate 11, move the fixing rod 18 into the limiting hole 23. The spring 21 will then limit the fixing rod 18 inside the limiting hole 23, thus limiting the clamp 22. This avoids the cumbersome process of changing the clamp 22, thereby improving the overall test efficiency and saving time and costs.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
