Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, specifically relating to a quick-assembly and disassembly tooling for the traveling block pin of oil drilling equipment. Background Technology

[0002] The traveling block is a crucial piece of equipment required for oilfield drilling and workover operations. During operation, in addition to its own weight, it supports the weight of top drives, lifting rings, clamps, casing, tubing, drill pipe, sucker rod, and other equipment. Its main function is to suspend or lift lifting tools, or to pull out the drill string when obstructed, and to clear downhole faults. During operation, it withstands tensile, compressive, and bending stresses of tens or even hundreds of tons longitudinally. During retrieval or unsticking, it may experience stresses exceeding its rated load, and due to frequent disassembly, it is highly susceptible to wear and damage. Figure 3 The number 2 shown is a pin used in oil drilling site installation between the traveling block and the hook. The clearance between this pin and the pin hole on the connecting lug plate of the traveling block is too small, and the front end of the pin is flat, making installation difficult and prone to damaging the threads at the front end during installation. To solve these problems, it is necessary to design a tooling specifically for the installation and disassembly of this pin. Utility Model Content
