A kind of oil pipe remote control transfer machine

Abstract

The invention discloses an oil tube remote control mobile device, and belongs to the field of well service equipment. The device comprises a slideway assembly, an automatic return tackle, a main rack,a tube taking and placing mechanism, an electrically controlled hydraulic device and a hand-held remote controller. The slideway assembly comprises a slideway, a support guide rail, slideway rollingwheels and a lifting machine. The slideway and the support guide rail are provided with rectangular grooves, wheels of the automatic return tackle can move forward and backward in the rectangular groove of the slideway, the slideway moves forward and backward in the rectangular groove of the support guide rail, and the front end of the support guide rail is driven by the lifting machine to do lifting motion. The tube taking and placing mechanism comprises a support plate, a tube taking arm, a tube jacking piston and a tube placing arm. An oil tube on the slideway is ejected out through the tube jacking piston and rolls down onto a tube rack along the tube placing arm; the oil tube on the tube rack is lifted and turned onto the slideway through the tube taking arm. The hand-held remote controller is in wireless connection with the electrically controlled hydraulic device, and then movement of the slideway, the lifting machine, the tube jacking piston and the tube taking arm is driven remotely. By means of the mobile device, oil tube screw thread damage can be avoided.

Description

technical field [0001] The invention relates to the field of workover equipment, in particular to an oil pipe remote control transfer machine. Background technique [0002] During workover operations in oil and gas fields, it is often necessary to pull out and run in a plurality of oil pipes connected in sequence in oil, gas, and water wells (that is, the lifting operation of oil pipes). After the multiple oil pipes are taken out from the well, they need to be moved to the pipe rack in order to arrange them neatly. When the oil pipes are lowered, they are moved from the pipe rack to the wellhead in the required order, and run into the well one by one. When the oil pipe is transferred manually, it is labor-intensive, takes a long time, and there are safety risks. Therefore, it is very necessary to provide a device capable of automatic oil pipe transfer. [0003] The prior art provides an oil pipe transfer machine, which includes: a main frame, a pick-and-place pipe mechanis...

AI Technical Summary

Problems solved by technology

Third, when the V-shaped slideway flips and throws the tube, it is easy to cause the rack to shake and become unstable

Finally, and more importantly, the existing models are not suitable for the unmanned operation of the wellhead to automatically lift and lower the tubing
