Description

TECHNICAL FIELD

[0001] The present application relates to the field of oil extraction, and particularly to a multi-plate spliced screw installation channel. BACKGROUND

[0002] The existing hoist for repairing well pipes in oil extraction wells mostly drags a flexible steel wire rope by a power machine to lift the well pipe under the ground to the ground for repair or replacement. It should be pointed out here that the flexible steel wire rope is more suitable for upward lifting, and can only be lowered back to the position for the next lifting of the well pipe by means of the gravity of the tool assembly and overcoming a series of transmission resistances. In order to make it quickly fall back, a series of counterweights are generally configured, which also increases the energy consumption. In addition, the conveying capacity is low, the lifting height is limited, and in the long-term use process, it is difficult to run stably and reliably, and the hoist lifting components are prone to failure, causing the load to fall, which poses a certain safety hazard, and has some problems such as high maintenance frequency.
