Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil drilling technology, and more specifically, to a simple power faucet anti-torque rope pretensioning force measuring tool and application device. Background Technology
[0002] During oil drilling, it is necessary to measure the preload of the power swivel's anti-torque rope. However, due to space and environmental constraints, the measurement process is cumbersome. For example, drilling sites are densely packed with equipment, rope installation spaces are narrow, and measuring tools are difficult to fit precisely. Furthermore, dust and vibration in the field can interfere with the measurement data. Rope preload needs to be measured when the equipment is stationary or under specific operating conditions, resulting in short working intervals; stopping the machine for measurement will affect the construction progress. At the same time, long-term operations require regular re-inspection, and frequent disassembly or adjustment of the rope increases labor and time costs and may also damage the rope. Utility Model Content
[0003] The purpose of this utility model is to provide a simple tool for measuring the preload of the anti-torque rope of a power faucet, so as to solve one or more problems mentioned in the background art.
[0004] To achieve the above objectives, a simple power faucet anti-torque rope pretension measuring tool includes an upper connecting seat, a lower connecting seat, and two tension cylinders located between the upper and lower connecting seats. The upper ends of the two tension cylinders are fixedly connected to the upper connecting seat, and the lower ends of the two tension cylinders are fixedly connected to the lower connecting seat. Screws are provided on the front and rear sides of the two tension cylinders, and the upper and lower connecting seats are connected by the two screws.
[0005] As a preferred and feasible approach, both tension cylinders are equipped with external pressure testing ports, on which pressure sensors are installed to display the current tension value of the rope.
[0006] As a preferred embodiment, the tension cylinder includes a cylinder liner and a piston rod disposed inside the cylinder liner. The output end of the piston rod is connected to a lug nut. A guide ring is disposed between the lower end of the piston rod and the inner contact surface of the cylinder liner. A guide copper sleeve is fitted between the upper end of the cylinder liner and the contact surface of the piston rod. A sealing ring is disposed above the guide copper sleeve.
[0007] This utility model also provides an application device for measuring preload, which adopts the aforementioned simple power faucet anti-torque rope preload measuring tool, and also includes an anti-torque rope, a wire rope sling, and a spiral buckle. The upper end of the preload measuring tool is connected to the anti-torque rope through the spiral buckle, and the other end of the anti-torque rope is connected to the lower end ear plate of the derrick crane. The lower end of the preload measuring tool is fixedly connected to the well platform ear plate.
[0008] As a preferred and feasible method, the lower end of the anti-torque rope passes through the wire rope loop and is connected to the upper end of the spiral buckle, and one end of the wire rope loop and the anti-torque rope are fixed by a wire rope clamp.
[0009] Compared with the prior art, the beneficial effects of this utility model are: This invention is easy to install, carry, and use. The upper end of the preload measuring tool 5 is connected to the lower end of the spiral buckle 4. The lower end of the preload measuring tool is connected to the well platform ear plate 7 via a connecting pin 6. The upper end of the anti-torque rope 1 is connected to the lower ear plate of the derrick. The lower end of the anti-torque rope passes through the wire rope loop 3 and connects to the upper end of the spiral buckle 4, then is fixed by the wire rope clamp 2. Therefore, this invention can adjust the preload of the anti-torque rope 1 by adjusting the extension and retraction of the spiral buckle. The current rope tension value is obtained through a pressure sensor, ensuring that the preload meets the standard and remains stable, thereby guaranteeing the safety, stability, and efficiency of drilling operations.

[0014] like Figure 1-4 As shown, a simple power faucet anti-torque rope preload measuring tool includes a nut 52, an upper connecting seat pin 53, a lower connecting seat pin 58, an upper connecting seat 51, a lower connecting seat 59, and two tension cylinders 54 located between the upper connecting seat 51 and the lower connecting seat 59. The upper ends of the two tension cylinders 54 are fixedly connected to the upper connecting seat 51 via the upper connecting seat pin 53, and the lower ends of the two tension cylinders 54 are fixedly connected to the lower connecting seat 59 via the lower connecting seat pin 58. Screws 55 are provided on both the front and rear sides of the two tension cylinders 54, and the upper connecting seat 51 and the lower connecting seat 59 are connected by the two screws 55.
[0015] It should be noted that both tension cylinders 54 are equipped with external pressure measuring ports, and pressure sensors 57 are installed on the pressure measuring ports. The pressure sensors 57 are used to display the current tension value of the rope.
[0016] like Figure 2 The diagram shows a schematic of a tension cylinder. The tension cylinder 54 comprises a lug nut 541, a piston rod 542, a sealing ring 543, a guide sleeve 544, a guide ring 545, a cylinder liner 546, and a cylinder head 547. The piston rod 542 is located inside the cylinder liner, and the cylinder head 547 is located at the other end of the cylinder liner. The output end of the piston rod 542 is connected to the lug nut 541. A guide ring 545 is provided between the lower end of the piston rod 542 and the inner contact surface of the cylinder liner 546. A guide sleeve 544 is fitted between the upper end of the cylinder liner 546 and the contact surface of the piston rod 542. A sealing ring 543 is located above the guide sleeve 544.
[0017] This utility model also provides an application device for measuring preload, which uses the aforementioned simple power faucet anti-torque rope preload measuring tool. It further includes an anti-torque rope 1, a wire rope sling 3, and a spiral buckle 4. The upper end of the preload measuring tool 5 is connected to the anti-torque rope 1 via the spiral buckle 4. The other end of the anti-torque rope 1 is connected to the lower end ear plate of the derrick crane. The lower end of the preload measuring tool 5 is fixedly connected to the well platform ear plate 7. Specifically, the lower end of the anti-torque rope 1 passes through the wire rope sling 3 and connects to the upper end of the spiral buckle 4. The upper end of the wire rope sling 3 and the anti-torque rope 1 are fixed together by a wire rope clamp 2. The spiral buckle 4 includes a buckle body and adjusting nuts at both ends. By rotating the corresponding adjusting nuts, the length of the spiral buckle 4 can be adjusted, thus adjusting the extension and retraction of the spiral buckle. Therefore, when installing the preload measuring tool, first loosen the nuts at both ends of the screw completely and fully retract the rod chamber of the tension cylinder. Then, fix the tension cylinder between the upper and lower connecting seats and lock the nuts at both ends of the screw. At this time, when adjusting the extension and retraction of the spiral buckle, the screw is the main force-bearing component, and the tension cylinder is not subject to the tension of the rope.
[0018] It should be noted that the principle of the application device includes: the upper end of the preload measuring tool 5 is connected to the lower end of the spiral buckle 4; the lower end of the preload measuring tool is connected to the well platform ear plate 7 via a connecting pin 6; the upper end of the counter-torque rope 1 is connected to the lower ear plate of the derrick crane; the lower end of the counter-torque rope passes through the wire rope loop 3 and is connected to the upper end of the spiral buckle 4, and then fixed by the wire rope clamp 2. Thus, the preload of the counter-torque rope 1 can be adjusted by adjusting the extension and retraction of the spiral buckle. The current rope tension value is displayed by the pressure sensor of the tension cylinder on the preload measuring tool. This device is easy to install, convenient to operate, and reliable in use.
