Description

Technical Field

[0001] This utility model relates to the technical field of hook head straightening equipment, and more specifically, to an elastically reset type hook head straightening equipment. Background Technology

[0002] Hook straightening equipment is a device used to adjust, calibrate, or stabilize the position of hooks (such as lifting hooks, connecting hooks, and end effectors of robotic arms) to ensure that they maintain the correct posture during operation and avoid tilting, swaying, or misalignment. This type of equipment is widely used in hoisting machinery, automated production lines, oil drilling, marine engineering, and other fields.

[0003] Elastic centralizers are widely used wellbore centralizing tools in oil drilling. Their core feature is that they adapt to changes in wellbore size through elastic deformation and return to their original shape after passing through a reduced-diameter section, ensuring that the drill string or casing is centered.

[0004] Existing flexible centralizers are often divided into integral or split types, but the difference between the two is only the connection method of the end ring, not the connection relationship between the end ring and the spring plate. The end ring and the spring plate are both integral, which makes them occupy a lot of space during transportation and easy to be collided. In addition, the end ring and the spring plate cannot be replaced, which is not conducive to use. Utility Model Content

This device involves inserting a split end ring into a spring plate component, then attaching the split end ring to the well shaft, aligning the split end ring with it, and finally assembling the split end ring using a second fixing bolt. During transportation, the internal components can be transported separately, reducing the space required for transport and minimizing the risk of collisions during transport. All components within the device are replaceable, reducing maintenance costs and facilitating use.

Then, the spring plate component is fixed between the separate end rings 1 using a first fixing bolt 8. Afterward, the assembled side separate end ring 1 is attached to the well shaft, and the other assembled side separate end ring 1 is aligned with it. Finally, the upper and lower side separate end rings 1 are assembled using a second fixing bolt 9. During transportation, the internal components can be transported separately, reducing the space required for transportation and minimizing the risk of collisions. All components within the device can be replaced, reducing maintenance costs and facilitating use.
