[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-3 As shown, the present application provides a catwalk machine transport device for a chuck / universal joint, which mainly includes an H-shaped steel 1, an upper stopper 3, a mounting pad 4, a tail side sealing plate 7, a tail top plate 8, a tail sealing plate 9, a reinforcing rib plate 10, etc.:

[0031] The H-shaped steel 1 should be selected to meet the load-bearing requirements of the chuck 104 / universal joint 102. Other profiles can also be selected according to project needs. The H-shaped steels 1 on both sides are positioned at a certain distance according to the layout requirements of the chuck 104 / universal joint 102, and their flanges are butt-welded to the panels 13. The front / middle connecting steel plates 5 are set on the opposite side of the structure corresponding to the mounting pad 4, and are welded to the H-shaped steels 1 and panels 13 on both sides to support and transmit relevant torque.

[0032] The reinforcing elbow plate 10 is arranged at the reverse side of the web plate of the H-shaped steel 1, and a lightening hole is arranged in the middle. The semicircle of the lightening hole should be appropriately enlarged to avoid stress concentration. The bottom plate 11 and the bottom stopper 12 are correspondingly welded below the reinforcing elbow plate 10. The thickness and shape of the above-mentioned three parts should be fully matched with the size of the front end structure of the catwalk machine 103 and meet the strength analysis calculation of the catwalk moving device 101.

[0033] The tail connecting steel plate 6, the tail side sealing plate 7 and the tail top plate 8 form a five-surface structure, and the bottom space is matched with the hanging buckle of the front end structure of the catwalk machine 103. According to different front end structures of the catwalk machine 103, the catwalk moving device 101 can be stably arranged on the front end structure of the catwalk machine 103, and the stress of the catwalk moving device 101 can be effectively transferred to the front end structure of the catwalk machine 103.

[0034] The hoisting eye plate 2 is used for hoisting the catwalk moving device 101, and can also be used for further binding and fixing the chuck 104 / universal joint 102.

[0035] The size of the mounting pad 4 can be matched with the size of the lower structure of the chuck 104 / universal joint 102, and the tail end can be appropriately beyond the outer circle of the lower structure of the chuck 104 / universal joint 102, so as to consider the case that the chuck 104 / universal joint 102 is arranged with deviation. The positioning of the catwalk moving device 101 is preferably not beyond the inner circle of the lower structure of the chuck 104 / universal joint 102. The mounting pad 4 is uniformly arranged below the lower structure of the chuck 104 / universal joint 102, and is used for bearing and transferring the weight of the chuck 104 / universal joint 102.

[0036] The upper stopper 3 is positioned inside the inner circle of the lower structure of the chuck 104 / universal joint 102, and is uniformly arranged. The upper stopper 3 is used for blocking the chuck 104 / universal joint 102 which may be inclined during the moving process. Therefore, the height of the upper stopper 3 should be appropriately increased, so as to not interfere with the upper structure of the chuck 104 / universal joint 102. The area where the upper stopper 3 may contact the chuck 104 / universal joint 102 is provided with an anti-collision rubber block, so as to buffer the knocking problem during hoisting. The upper stopper 3 and the mounting pad 4 can be uniformly arranged at the same angle according to the actual situation of the specific project, or can be arranged in a staggered manner. As shown in the figure, the staggered arrangement is beneficial to the design of the structure reverse side reinforcement which becomes relatively simple. Figure 2

[0037] Referring to Figure 1 , the specific operation method of the present application is:

[0038] ​When the chuck 104 / gimbal 102 needs to be moved to the rotary table, first, the catwalk machine moving device 101 is hoisted to the front end structure of the catwalk machine 103, and then the chuck 104 / gimbal 102 is hoisted to the catwalk machine moving device 101, so that the catwalk machine 103 can move the chuck 104 / gimbal 102 to the wellhead center near the drilling platform surface, and then the chuck 104 / gimbal 102 is hoisted by the relevant hoisting tool in the derrick to be placed on the designated position on the upper part of the rotary table, so that the moving and installation of the chuck 104 / gimbal 102 are completed; when the chuck 104 / gimbal 102 needs to be moved to the storage position, the above-mentioned reverse steps can be used to complete the moving.

[0039] As shown in Figure 4 Because the shape / dimension of the lower structure of the chuck 104 is similar to that of the gimbal 102, the catwalk machine moving device 101 can also move the chuck 104 alone according to the specific operation process requirements.

[0040] In summary, the above is only a preferred embodiment of the present application, and does not limit the protection scope of the present application. Any equivalent changes and modifications made according to the scope and content of the present patent are within the scope of the present patent.
