In the initial state, the positioning mechanisms 4 positioned at two sides of the pipe conveying mechanism 1 are not in contact with the petroleum pipe, when the petroleum pipe is blocked by the baffle plate 2, the pipe conveying mechanism 1 stops running, the driving plate 33 is driven to descend by the extension of the movable end of the first electric cylinder 34, the driving plate 33 drives the two driving rods 35 to synchronously move close to each other through the driving groove 331, meanwhile, the two driving rods 35 are limited by the limiting groove 322, the two driving rods 35 synchronously move close to each other on the same water surface level, namely, the positioning mechanisms 4 positioned at two sides of the pipe conveying mechanism 1 are driven to gradually approach the petroleum pipe until the positioning mechanisms 4 are in contact with the surface of the petroleum pipe, and the petroleum pipe is centrally arranged in the pipe conveying mechanism 1 due to uniform stress at two sides of the petroleum pipe, and meanwhile, the driving plate 33 descends to drive the code spraying mechanism 5 to be close to the surface of the petroleum pipe, so that the adjustment work before code spraying is completed.

It should be noted that, the arc surface at the bottom of the pressing plate 55 is always located below the spraying head 52 of the code spraying machine, and in the descending process of the driving plate 33, the pressing plate 55 can contact with the petroleum pipe before the spraying head 52 of the code spraying machine, so that a distance is kept between the spraying head 52 of the code spraying machine and the petroleum pipe, damage of the spraying head 52 of the code spraying machine due to collision is avoided, the pressing plate 55 extrudes the upper side of the petroleum pipe, and the pressing plate 55 is matched with the two positioning mechanisms 4 to fix the pipe in three directions. Meanwhile, when the pipe continuously moves to the code spraying station through the pipe conveying mechanism 1, friction occurs between the pressing plate 55 and the surface of the petroleum pipe, so that impurities such as dust on the surface of the pipe are removed, and the definition of code spraying information is ensured.
The positioning mechanism 4 is used for clamping the petroleum pipe and realizing the relative fixation of the code spraying mechanism 5 and the pipe.
Specifically, as shown in fig. 6, the positioning mechanism 4 includes two sets of rollers 47 that keep the same with the transporting direction of the pipe transporting mechanism 1, the two sets of rollers 47 are respectively disposed on two sides of the pipe transporting mechanism 1, each set of rollers 47 is provided with two, one end of the two rollers 47 on the same side, which deviate from the pipe transporting mechanism 1, is provided with a mounting frame 41 together, the upper end of the mounting frame 41 is fixedly connected with the lower end of the driving rod 35, and the lower end of the mounting frame 41 is fixedly connected with the upper end of the reinforcing rod 36. When the first electric cylinder 34 drives the code spraying mechanism 5 to move downwards to approach the pipe, the two groups of rollers 47 move continuously in opposite directions, and finally the four rollers 47 are attached to the outer wall of the pipe to clamp the pipe.
In practical application, the pipes have various different types, and the calibers of the pipes with different types are different, so that in order to adapt to petroleum pipes with different calibers, the invention can also adjust the distance between two rollers 47 on the same side along the vertical direction, and the specific adjustment is driven by the power module. The specific structure of power module is as shown in fig. 6, it is including installing at the inside second electronic jar 42 of mounting bracket 41, mounting bracket 41 is U-shaped structure, guide bar 43 is installed to the one end that mounting bracket 41 is close to tubular product transport mechanism 1, guide bar 43 is V-arrangement, sliding sleeve 44 is all installed at the both ends of guide bar 43, sliding sleeve 44 is the slope setting with mounting bracket 41, slide bar 45 has all been cup jointed in the activity of two sliding sleeves 44, the output of second electronic jar 42 runs through guide bar 43 and rotates and be connected with two connecting rods 48, two connecting rods 48 are around dislocation set with the output of second electronic jar 42 as the center, two connecting rod 48 other ends are rotated through the pivot with two slide bars 45 respectively and are connected, two slide bars 45 keep away from the one end of mounting bracket 41 respectively with gyro wheel 47 fixed connection. The present invention will be described by taking the example of shortening the distance between the two rollers 47 on the same side: the second electric cylinder 42 is started, the movable end of the second electric cylinder extends and drives the two connecting rods 48 to synchronously rotate towards each other, so that an included angle between the two connecting rods 48, which is close to one side of the mounting frame 41, is reduced, and meanwhile, the other ends of the two connecting rods 48 respectively pull the two sliding rods 45 to synchronously move along the sliding sleeve 44, so that the two rollers 47 gradually approach in the vertical direction.
After the roller 47 contacts with the surface of the petroleum pipe, in order to avoid the situation that the petroleum pipe is not positioned between the two rollers 47, one of the rollers 47 cannot be completely contacted with the surface of the petroleum pipe, and then the pipe clamping is unstable. In the invention, a telescopic mechanism 46 is arranged between a roller 47 and a slide rod 45, and the telescopic mechanism 46 can drive the roller 47 to move along the radial direction of the pipe. As shown in fig. 7, as one embodiment of the telescopic mechanism 46: the telescopic mechanism 46 comprises a movable rod 462 which is sleeved in the inner cavity of the sliding sleeve 461 in a sliding manner, one end of the sliding sleeve 461 far away from the movable rod 462 is fixedly connected with the sliding rod 45, a first spring 463 is commonly arranged between the movable rod 462 and the bottom wall of the inner cavity of the sliding sleeve 461, the other end of the movable rod 462 is fixedly connected with the frame body in the roller 47, and the first spring 463 is always in a compressed state.

In addition, because the surface of the petroleum pipe is in a cambered surface structure, when the roller 47 contacts with the surface of the petroleum pipe, the contact surface of the roller 47 and the pipe is limited, so the contact surface of the roller 47, which is close to the central axis of the petroleum pipe, is provided with the inclined surface 471, the contact area of the roller 47 and the surface of the petroleum pipe is increased through the inclined surface 471, and the contact stability is improved. Meanwhile, the roller 47 is made of rubber, and the contact area between the roller 47 and the surface of the petroleum pipe is further increased by utilizing the deformable characteristic of rubber.
