Problems solved by technology
The mechanical transmission type pipe arrangement is huge in equipment and takes up a lot of space, which is inconvenient for the on-site layout of oil and gas operations. At the same time, the traditional method is not stable, it cannot realize stepless speed change, and the transmission accuracy is low; the transmission accuracy of the electronic control transmission method is acceptable, but The cost of electronic control components is high, and it is not conducive to explosion-proof in the oil and gas operation site, so special explosion-proof treatment is required

Embodiment Construction
[0023] Such as figure 1 or figure 2 As shown in one of them, a hydraulic automatic pipe rowing device includes a pipe rower 10, a guide rod 12, a screw 13 and a rotating reel 8. The pipe rower 10 is provided with a touch block 11, and the pipe rower 10 is set On the screw rod 13 , the pipe rower 10 is driven by a hydraulic system, and can move back and forth along the screw rod 13 axially under the guidance of the guide rod 12 .
[0024] The hydraulic system includes a driving oil circuit and a control oil circuit. The driving oil circuit includes a fuel tank 7, a hydraulic pump 6, a hydraulic valve 3, a hydraulic motor 15 and an on-off valve 1. The hydraulic pump 6 is driven by a rotating drum 8, And the oil inlet of hydraulic pump 6 is connected with oil tank 7, and the oil outlet of hydraulic pump 6 is connected with hydraulic valve 3, and described hydraulic valve 3 is also connected with hydraulic motor 15 and fuel tank 7 respectively, and the power of hydraulic motor 1...

The invention discloses an automatic hydraulic pipe arrangement device which comprises a pipe arrangement device, a guide rod, a screw rod and a rotary coiling drum, wherein a touch block is arranged on the pipe arrangement device; and the pipe arrangement device is arranged on the screw rod and driven by a hydraulic system, and can reciprocate axially along the screw rod under the guiding of the guide rod. According to the device, the device is driven by hydraulic pressure, so that stepless speed regulation is realized; the anti-explosion performance is good, and the reliability is high; and at the same time, the device is applicable to operation of continuous pipes of various specifications, so that the production cost is reduced.
Description
technical field [0001] The invention relates to an automatic pipe arrangement device, in particular to a hydraulic automatic pipe arrangement device. Background technique [0002] A coiled tubing rig reel is a device used in oil and gas operations (workover or drilling). When the reel is winding or releasing the coiled tubing, in order to prevent the coiled tubing from being disordered, it is required that the rotating reel needs to move back and forth in the axial direction during the winding process of the rotating reel, so that the coiled tubing is fully covered on the rotating reel. After one layer, the next layer is reversed and the continuous tubes are tightly arranged on the rotating reel. When it is necessary to unwind the roll, it can be opposite to the direction of movement of the roll. Therefore, the automatic pipe arrangement device is a key device on the reel of the coiled tubing drilling rig. [0003] At present, there are two types of driving systems...
