Description

Technical Field

[0001] The utility model relates to the technical field of casing power tongs, in particular to a casing power tong with a straightening mechanism. Background Art

[0002] Power tongs are a tool with strong mobility and high operating efficiency. They are usually composed of a pliers head, a driving part, a control part, etc. The driving part mostly uses power equipment such as electric motors and hydraulic motors, and the pliers head is controlled by the control part. Power tongs can also achieve clamping operations on different materials by replacing pliers heads of different shapes. For example, they can be used for pipe clamping, as well as bending and embossing in sheet metal processing. Power tongs are flexible to operate and can adapt to clamping operations in special situations such as high altitude and narrow areas.

[0003] When using a casing power tong, an operator is generally required to hold the casing power tong and the casing to adjust the distance between the tong and the casing. The adjustment can only be made by operating experience to make them relatively at the same horizontal position. At the same time, when raising or lowering the height, it cannot be automatically raised or lowered according to its parameters. This not only reduces the docking accuracy, but also increases the burden on the operator. Therefore, a casing power tong with a straightening mechanism is urgently needed to overcome the above defects. Utility Model Content
