Problems solved by technology

[0002] During workover operations, the length of the tubing needs to be manually measured on site (the distance from the outside of the coupling to the threaded thread). There are a large number of tubing on site (hundreds of pieces), and two people are required to stand at both ends of the tubing and pull a tape to measure and record. Time-consuming, labor-intensive, low-efficiency, and error-prone

[0087] During the implementation of the technical solution of the present invention, the inventor found that when the first baffle 310 and the second baffle 520 clamp the pipe 4, the middle part of the pipe 4 will bend, which will affect the accuracy of the measurement, and may even It will cause a safety accident.

[0088] In order to solve the above technical problems, the technical solution of the present invention further includes a safety righting mechanism 6 . Figure 6 It is a schematic structural diagram of the safety righting mechanism 6 in an automated catwalk according to an embodiment of the present invention, wherein the safety righting mechanism 6 is in an open state. Figure 7 The safety righting mechanism 6 in the closed state.

[0089] Such as Figure 6 and Figure 7 As shown, the safety righting mechanism 6 includes a righting arm 601 and a righting hydraulic cylinder 603 . One end of the righting liquid cylinder 603 is pivotally connected to the first en...

no. 3 approach

[0091] Such as Figure 9 As shown, a method for measuring the length of a pipe using an automated catwalk mainly includes the following steps:

[0092]S200, clamping the pipe 4 in the length direction of the pipe 4;

[0093] S400, acquiring displacement information of the piston rod of the length measuring cylinder 530;

[0094] S600. Calculate the length of the pipe 4 according to the displacement information.

[0095] Further, as Figure 10 As shown, before the step S200 of clamping the pipe in the length direction of the pipe 4, it also includes:

[0096] S100 , make the second baffle 520 face the first baffle 310 .

[0097] Specifically, the first baffle 310 is fixed at one end of the receiving slot 3 , and the second baffle 520 can rotate or move to a position opposite to the first baffle 310 , so as to clamp the pipe 4 .

[0098] Further, before the step of clamping the pipe 4 in the length direction of the pipe 4 includes:

[0099] Righting the pipe so that the pi...
