[0033] As some embodiments of the present invention, Figure 1 As shown, the second limit plate 32 is located on the third pipe section 313, and the second limit plate 32 is arranged around the outer circumference of the third pipe section 313. Both ends of the second limit plate 32 are respectively connected to the inner wall of the chuck 4. The main function of the second limit plate 32 is to limit the movement range of the chuck 4 in the first direction. Through the action of the second limit plate 32, it can be ensured that the chuck 4 will not move excessively due to vibration, external force, etc., so as to maintain the overall stability and safety of the chuck 4 and the universal joint 5 when they are placed in combination.

[0034] As some embodiments of the present invention, Figure 2 As shown, a rubber pad 321 is provided at the outer edge of the second limiting plate 32 to buffer the movement collision between the chuck 4 and the universal joint 5 and the second limiting plate 32. The rubber pad 321 is provided at the outer edge of the second limiting plate 32, that is, the edge portion where the second limiting plate 32 may contact the chuck 4 and the universal joint 5. The main function of the rubber pad 321 is to buffer and reduce the collision impact between the chuck 4 and the universal joint 5 and the second limiting plate 32 during storage or movement. Through the elastic effect of the rubber pad 321, the energy generated by the collision can be absorbed and dispersed, thereby reducing the risk of damage to the chuck 4 and the universal joint 5 and the storage device itself.

[0035] As some embodiments of the present invention, Figure 2 As shown, a sealing plate 315 is provided at one end of the third pipe section 313 away from the second pipe section 312, which is used to block the third pipe section 313 and provide a welding position for the hoisting plate eye 314. By providing the sealing plate 315 at one end of the third pipe section 313 away from the second pipe section 312, the combined storage device of the chuck 4 universal joint 5 of the present invention is significantly improved in terms of safety, stability and protection of the chuck 4. The sealing plate 315 can not only block the third pipe section 313 and provide a welding position for the hoisting plate eye 314, but also improve the overall stability and safety of the storage device.

[0036] As some embodiments of the present invention, Figure 1 As shown, the end of the first pipe section 311 close to the second pipe section 312 is recessed toward the direction of the panel 1 to form a first flared area, the end of the second pipe section 312 close to the third pipe section 313 is recessed toward the direction of the panel 1 to form a second flared area, and the end of the second pipe section 312 close to the first pipe section 311 is threadedly connected to the first flared area, and the end of the third pipe section 313 close to the second pipe section 312 is threadedly connected to the second flared area. By respectively providing the first flared area and the second flared area on the first pipe section 311 and the second pipe section 312, and connecting the pipe sections together by screw connection, the chuck 4 universal joint 5 combined storage device of the present invention is significantly improved in terms of structural strength, connection reliability and installation convenience. This connection method not only improves the overall performance and safety of the storage device, but also reduces the safety risks caused by loose connection or falling off. At the same time, the design of the flared area also takes into account the stability and durability requirements of the storage device during long-term use, ensuring its stability and reliability under harsh conditions.

[0037] Furthermore, the first expansion area on the first pipe section 311 is a expansion female end, the end of the first pipe section 311 away from the first expansion area is a male end, the second expansion area on the second pipe section 312 is a expansion female end, the end of the second pipe section 312 away from the second expansion area is a male end, and the end of the third pipe section 313 close to the second pipe section 312 is a male end.

[0038] The use process of the present invention is as follows: first, the universal joint 5 and the chuck 4 are moved as a whole onto the panel 1, and then the first pipe section 311 is hoisted from the inner holes of the chuck 4 and the universal joint 5 into the second tube body 22 using a hoist, and then one end of the second pipe section 312 is inserted into the expanded female end of the first pipe section 311 using a hoist, and the male end of the second pipe section 312 is visually checked to be completely seated on the flared female end of the first pipe section 311. Continue to use the hoist to insert the male end of the third pipe section 313 into the expanded female end of the second pipe section 312, and visually check that the male end of the third pipe section 313 is completely seated on the flared female end of the second pipe section 312. During the hoisting and lowering process, attention should be paid to controlling the gap between the second limit plate 32 on each third pipe section 313 and the inner hole of the chuck 4 to minimize the collision during hoisting. At this point, the overall storage and installation of the chuck 4 and the universal joint 5 is completed. When the chuck 4 and the universal joint 5 need to be moved to the wellhead position on the drilling floor, the above steps can be used in reverse to complete the process.

[0039] In summary, the embodiment of the present invention provides a chuck 4 universal joint 5 combined storage device, which has the following beneficial effects compared with the prior art: 1) the panel 1 is used to directly place the chuck 4 and the universal joint 5, providing a flat storage surface for the chuck 4 and the universal joint 5; 2) the support assembly 2 provides a stable supporting force for the panel 1, and the support assembly 2 includes a first tube body 21 and a second tube body 22.
