Ground automatic transmission device for oil pipe and drill pipe lifting operation

Abstract

The invention provides a ground automatic transmission device for oil pipe and drill rod tripping operation. The device comprises a control cabinet, an air compressor, a hydraulic pump, an overturn mechanism, a slideway mechanism, a rolling platform overturn mechanism, a transmission mechanism, a speed regulating motor and an oil pipe bed lifting mechanism, wherein the air compressor and the speed regulating motor are power sources of the overturn mechanism, the slideway mechanism and the transmission mechanism, the hydraulic pump is the power source of the oil pipe bed lifting mechanism, and the air compressor, the speed regulating motor and the hydraulic pump are all controlled through a control cabinet which is provided with a programmable logic control (PLC) system; an oil pipe or a drill rod which is tripped from a well slides into the slideway mechanism, goes to the transmission mechanism through the overturn mechanism, then reaches the rolling platform overturn mechanism, and is transmitted into an oil pipe bed through the rolling platform overturn mechanism for natural arrangement; the oil pipe bed lifting mechanism lifts and rolls the oil pipe or the drill rod which is about to be delivered into the well from the oil pipe bed into the rolling platform overturn mechanism, and the oil pipe or the drill rod is transmitted onto the slideway mechanism in a reverse process; and the oil pipe or the drill rod is delivered to the well mouth from the slideway mechanism to complete the ground transmission work, and one person can complete the whole process by operating the keyboard of the control cabinet.

Description

technical field [0001] The invention relates to a ground automatic transmission device for oil pipes and drill rods used in oil well workover operations or drilling operations, which reduces the labor intensity of workers and improves workover or drilling work efficiency. Background technique [0002] At present, workover operations and drilling operations in oilfields, and the transportation of the oil pipes or drill pipes on the ground are all done manually. In one operation well, hundreds of oil pipes or drill pipes are all carried by people. Rolling, pulling by people, and laying by people to complete the transmission of oil pipes or drill pipes on the ground, each oil pipe weighs 80-100 kg, and each drill pipe weighs more than 150 kg. The transmission frequency is high and the labor intensity is high, especially in the During the battle, the workers worked continuously for more than ten hours, and they were exhausted. In the case of severe physical exhaustion, personal ...
