Cofferdam type pipe rod conveying and discharging device

Abstract

The invention discloses a cofferdam type pipe rod conveying and discharging device. The conveying and discharging device is composed of five cofferdams and comprises a near-end auxiliary material frame, a main material frame, an auxiliary material frame and a far-end auxiliary material frame, the five cofferdams are each arranged to be a rectangular block, are sequentially arranged from left to right and are mutually fixed through rapid buckles, four stand columns with lifting adjusters are arranged at the bottoms of the four corners of the outer sides of the main material frame and the auxiliary material frame, the upper top ends of the front stand column and the rear stand column are each provided with a rectangular guide rail, the middle of the top face of each rectangular guide rail is provided with a rack, the front rectangular guide rail and the rear rectangular guide rail are each provided with a rectangular traveling mechanism matched with the guide rails to move, two output shafts of a speed reducer are respectively connected with couplings of two rolling mechanisms arranged on the two guide rails, and the rolling mechanisms are provided with drag chains which are mutually hinged with drag chain rods; grabbing manipulators consisting of manipulator support frames, hydraulic cylinders, shear fork frames and electric permanent magnets are respectively arranged below the front middle part and the rear middle part of the traveling mechanism; and a lifting machine for receiving and sending a pipe rod to a wellhead is longitudinally arranged on the right side of the near-end auxiliary material frame.

Description

technical field [0001] The invention relates to the technical field of oil well operations in oil fields, in particular to a cofferdam type pipe rod conveying and discharging device. Background technique [0002] At present, oil and water well workover operations in oil fields are mainly manual operations for tubing and sucker rods to be lowered or raised from the well, and the in-place discharge of the connecting rods is all manual operations. The work procedures are complex, heavy and unsafe. The cofferdam type pipe and rod conveying and discharging device is guided by the complete set of supporting equipment, and integrates all other operation automation devices except the operating power and lifting equipment on one chassis, including the cofferdam type chassis, automatic pipe discharge device, The four parts, including the automatic conveying device and the automatic control system, work independently with the operating power equipment, simplify on-site installation, an...
