Pipe string automatic delivery device

Abstract

The invention discloses an automatic delivery device for pipe strings, comprising: a ramp, a base, an upper traction system installed on the ramp, and a lower traction system installed on the base; the upper traction system includes: The upper tractor; the lower traction system includes: the lower tractor that moves along the base to transport the pipe string; the upper tractor includes: the main body of the upper tractor, the upper hook that can contact the end of the pipe string to push the pipe string to move and for A locking device that locks the position of the upper hook relative to the main body of the upper tractor; the lower tractor includes: the main body of the lower tractor, a lower push plate that can contact the end of the pipe string to push the movement of the pipe string, and is used to push the upper hook relative to A push rod that rotates on the main body of the upper tractor and an unlocking device that can unlock the locking device. The advantage of the present invention is that the upper tractor and the lower tractor realize the control of the upper hook through mechanical linkage, automatically lock and unlock the upper hook, so that the transfer of the lifting string between the upper tractor and the lower tractor is reliable. sex.

Description

technical field [0001] The invention relates to an automatic delivery device for pipe strings, which belongs to the technical field of oil and gas drilling and production equipment. Background technique [0002] Pipe string automatic conveying device, commonly known as power catwalk, is a conveying equipment in the technical field of oil and gas drilling and production equipment. The pipe string automatic conveying device includes a ramp, a base and a traction system for conveying pipe strings. According to the height of the drill floor, the pipe string automatic conveying device is divided into a low drill floor power catwalk and a high drill floor power catwalk. Due to the relatively low conveying height of the low rig power catwalk, usually only one traction system is set on the base, and the tractor moves along the base to transport the pipe string. However, the conveying height of the high-rig power catwalk is relatively high, and the upper traction system and the low...

Problems solved by technology

[0003] During the actual operation of the traditional high-drill power catwalk, it was found that the upper tractor or the lower tractor did not reach the pipe string transfer position, and the operation of the pipe string transfer occurred by the rotation of the flap or the hook, causing the pipe string The transfer cannot be completed accurately, and in severe cases, the pipe column may even be pushed off by the flap or the hook.
