Description

Technical Field

[0001] This utility model relates to the field of petroleum energy technology, specifically to a rotary lever power clamp. Background Technology

[0002] Petroleum refers to a mixture of liquid and solid hydrocarbons that occurs naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar, but conventionally, "petroleum" is still used to define "crude oil."

[0003] The current publication number CN208040331U discloses a power tong for oilfield drill pipes, including a base. Each of the four corners of the base is provided with a support cylinder running vertically through it. The lower surface of the base is provided with casters at the four corners and inside the support cylinders. A drive motor is embedded in the upper center of the base. The output end of the drive motor is provided with a turntable. The upper surface of the turntable is provided with semi-cylinders symmetrically arranged front and back. The lower parts of the semi-cylinders are symmetrically provided with a first adjusting column running front and back. The upper parts of the semi-cylinders are symmetrically provided with a second adjusting column running front and back. The middle of the first adjusting column is provided with a first fastening bolt running left and right.

[0004] To address the issues of high labor intensity and low efficiency in disassembling with mechanical clamps, existing technology involves using an adjusting cylinder to move the clamping cylinder up and down, aligning the clamping cylinder with the drill rod section. This allows for the disassembly and installation of the drill rod. However, this method still encounters situations where the drill rod needs to be fixed from one end of the rotating rod, rather than being directly clamped from its surface, leading to low disassembly and assembly efficiency.
