Description

Technical Field

[0001] This utility model relates to the field of anti-wear pair hanger technology, and in particular to an anti-wear pair hanger with a tapered shape. Background Technology

[0002] Lifting clamps are used to safely and stably hold tubing strings during operations such as lifting, lowering, and suspending them. In drilling and extraction operations in industries such as oil and mining, lifting clamps are indispensable tools for running drill strings, tubing, and casing. However, traditional lifting clamps have encountered numerous problems during long-term use.

[0003] Traditional lifting clamps, where they directly contact the tubing string, experience severe wear due to friction during frequent lifting and lowering operations. This not only reduces the clamp's lifespan and increases replacement costs but can also lead to a decrease in the clamp's gripping force on the tubing string, posing safety hazards. For example, in some oil well operations, severe clamp wear has caused the tubing string to slip during lifting, resulting in equipment damage and personnel injuries. Therefore, we propose a tapered, wear-resistant lifting clamp. Utility Model Content

When lifting the pipe column, the weight of the pipe column is transferred to the clamp body through the wear-resistant auxiliary clamp. Due to the effect of the tapered shape, the pipe column will slide relatively in the installation groove, thereby achieving automatic wedging and increasing the clamping force on the pipe column; the inner wall of the wear-resistant auxiliary clamp body is also provided with multiple protrusions or teeth, which can increase the friction with the surface of the pipe column and further improve the clamping stability;

The assembly locking frame rotates through the cooperation of the connecting block and the fixing pin, and the hanger body and the assembly locking frame are connected. The pressing block is controlled to drive the locking rod to descend, so that the locking rod can be inserted into the inner side of the limiting block, which can lock the assembly locking frame and the hanger body.

[0031] The wear-resistant auxiliary hanger body 5 is inserted into the inner side of the insertion slot 7 and locked in place by the fixing bolt 6. This allows the wear-resistant auxiliary hanger body 5 to be replaced in time after wear occurs. The assembly locking frame 2 rotates through the cooperation of the connecting block 4 and the fixing pin 3, connecting the hanger body 1 and the assembly locking frame 2.
