[0030] Among them, fixed support 4 includes first support 41 fixed on support plate 3 and first wheel frame 42 fixed on first support 41, and first guide wheel 43 hinged on first wheel frame 42, first wheel frame 42 and first guide wheel 43 are arranged in at least two groups in vertical direction on first support 41, and the two groups of first guide wheels 43 distributed vertically in the embodiment ensure that the pipe column stands vertically more stably, to avoid inclination leading to unable to be connected with wellhead.

[0031] Among them, movable support 5 includes second support 51 fixed on fixed seat 2 and second wheel frame 52 located in front of second support 51, at least two second guide wheels 53 are hinged on second wheel frame 52, first guide rod 54 is fixedly arranged in second support 51 and penetrates through second wheel frame 52, and the first guide rod 54 in the embodiment ensures the activity stability while providing the activity of second wheel frame 52 and second guide wheel 53.

[0032] Among them, driving mechanism 6 includes mounting seat 61 fixed on support plate 3, U-shaped frame 62 movably arranged at the front end of mounting seat 61 and connecting rod 63 hinged at the front end of U-shaped frame 62, connecting seat 64 hinged with the other end of connecting rod 63 is arranged in the inner side of second wheel frame 52, and the connecting seat 64 is arranged at the middle position of second wheel frame 52 in the embodiment, to ensure the uniformity of tension transmission while not affecting the pipe column limiting of second guide wheel 53, and driving mechanism 6 and the two groups of fixed support 4 form mutual avoidance, and the space utilization is higher.

[0033] The mounting base 61 is fixed with a hydraulic cylinder 65 whose output end is fixedly connected to the U-shaped frame 62. The U-shaped frame 62 is also fixed with a second guide rod 66 that slides through the mounting base 61. In this embodiment, the second guide rod 66 ensures the translational stability of the U-shaped frame 62 after the hydraulic cylinder 65 drives it.

[0035] In this embodiment, the side of the support plate 3 away from the fixed seat 2 is hinged with a hanging rod 7. The other end of the hanging rod 7 is hinged to a driving component that drives the support plate 3 to rotate. The hanging rod 7 can be directly linked with the rotation of the boom on the boom tilting seat 1, or it can be driven by an independent hydraulic component to drive the support plate 3 to rotate upward to fit with the boom tilting seat 1 and to unfold downward to be parallel to the ground.

[0036] It is understood that this utility model provides a foldable support plate on the rear side of the boom tilting seat. The support plate is located directly below the hook and has a U-shaped groove, which is used to position and guide the tubing string to dock with the wellhead after it is lifted. The fixed support and movable support on the support plate can restrict the radial movement of the tubing string, while multiple sets of guide wheels ensure the axial flexible movement of the tubing string, thereby accurately aligning it with the wellhead, improving convenience and safety, and realizing intelligent control through hydraulic drive.

[0037] A specific application of this embodiment is as follows: the boom tilting seat 1 is installed at the end of the vehicle-mounted integrated machine, the boom tilting seat 1 is equipped with a foldable boom, the upper end of the hanging rod 7 is hinged to the boom part, when the boom is folded horizontally to the roof of the vehicle, it will drive the hanging rod 7 to pull up, thereby attaching the support plate 3 to the rear end of the boom tilting seat 1. When the boom is vertically unfolded, the hanging rod 7 pushes down to drive the support plate 3 to unfold at the rear end of the boom tilting seat 1, and finally to a horizontal state. At this time, the movable support 5 is opened.

[0038] The support plate 3 can also be flipped using independent hydraulic components. When folded, it reduces the space occupied and fits more closely with the boom flipping seat 1. When unfolded, it ensures the guiding effect.

[0039] The tubing is placed directly in front of the U-shaped channel 31. One end of the tubing is lifted using the hook on the boom. When the tubing is fully lifted, the workers, with the help of the boom, move the tubing into the U-shaped channel 31. Since the movable support 5 is in the open position, the tubing can smoothly enter and contact the first guide wheels 43 on the two sets of fixed supports 4. At this time, the drive mechanism 6 pulls the movable support 5 until the tubing is in the U-shaped channel 31. Figure 3 As shown in the limit position, the tubing string is coaxial with the wellhead. The boom drives the tubing string to move downwards. Under the action of multiple guide wheels, the tubing string moves vertically downwards and smoothly enters the wellhead.

[0040] If the support plate 3 is overturned by independent hydraulic pressure, the support plate 3 can drive the fixed support 4 and the movable support 5 to overturn and fold at this time.
