The pipe feeding and length measuring work flow comprises the following steps:
Check if the oil pipe slide swing limiter 209 is installed correctly (on the opposite side to the pipe feeding side), and change the position if necessary. After the preparation, the "pipe feeding/taking over" function key on the remote controller (or the inner panel of the electric cabinet, the same applies below) is firstly pressed, the "pipe feeding" indicator light is on, then the "left side/reset" or "right side/reset" key (the hinged end of the conveying device is used for standing by people from left to right and the hinged end is used for separating towards the wellhead direction) is pressed, the pipe feeding side is selected, each power device enters the pipe feeding preparation state, namely, the driving rods of the first power device 202, the second power device 204, the fourth power device 211 and the fifth power device 303 on the pipe feeding side are retracted, the piston rod 3043 of the sixth power device 304 extends, and the third power device 206 enables the oil pipe slideway 205 to incline towards the pipe feeding side according to the selected action. When the oil pipe rolls into the picking hook 210, a start key of the remote controller is pressed, the driving rod of the fourth power device 211 extends out to pick the oil pipe into the oil pipe slideway 205, the third power device 206 acts to centralize the oil pipe slideway 205 to enable a V port of the oil pipe slideway to swing in the vertical upward direction, the driving rod of the fifth power device 303 extends out to lift the reference arm 301, the piston rod 3043 of the sixth power device 304 retracts, when the reference plate is extruded to a preset position by the oil pipe, the in-place sensor 3013 informs the measurement and control device to read the length data of the oil pipe, and the driving rod of the fifth power device 303 retracts to retract the reference arm 301. Then, the driving rod of the second power device 204 extends to convey the oil pipe slideway 205 and the oil pipe together forward to a proper position, meanwhile, the driving rod of the first power device 202 extends to lift the oil pipe to the height of the wellhead platform, after the oil pipe is taken away, a pipe conveying side key (left side/reset or right side/reset) is pressed, and all oil cylinders return to a preparation state to wait for a next conveying instruction.
The pipe unloading work flow comprises the following steps: checking whether the installation position of the oil pipe slide swing limiting piece 209 is correct (whether the oil pipe slide swing limiting piece is positioned on the side opposite to the pipe unloading side), if necessary, changing the positions, overlapping the pipe unloading arm 215 on the pipe unloading side, after the preparation work is finished, pressing a 'pipe unloading' function key, turning on a 'pipe unloading' indicator lamp, and then pressing a 'left side/reset' or 'right side/reset' key to select the pipe unloading side, wherein each oil cylinder enters a pipe unloading state, namely, the fourth power device 211, the driving rod of the fifth power device 303 and the piston rod 3043 of the sixth power device 304 on the corresponding sides are all in a retracted state, the driving rods of the first power device 202 and the second power device 204 are in an extended state, and the third power device 206 enables the oil pipe slide 205 to be upright. When the oil pipe slides into the oil pipe slideway 205, the start key is pressed, the driving rods of the first power device 202 and the second power device 204 are retracted, the third power device 206 acts to enable the oil pipe slideway 205 to topple towards the pipe unloading side, and the oil pipe rolls onto the oil pipe shelf along the pipe unloading arm 215. Pressing the unload side key ("left side/reset" or "right side/reset") all cylinders enter the take over preparation state waiting for the next "start" command.
The technical principle of the present invention is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the invention and should not be taken in any way as limiting the scope of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
