DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0021] The utility model provides a new type of drilling top drive balance assembly device, please refer to Figure 1-4 , including a guide rail 10, on which a traveling carriage 9 is slidably connected, on which a lifting ring 8 is hung, and on which a locking mechanism is arranged; under the action of the locking mechanism, the lifting ring 8 and the traveling carriage 9 are effectively prevented from being unhooked.

[0022] A drilling motor 5 is connected to the bottom of the lifting ring 8. Specifically, a lifting ear 51 is provided at the top of the drilling motor 5. The bottom of the lifting ring 8 is connected to the lifting ear 51 through a lifting ring pin 6. The output shaft of the drilling motor 5 is connected to the main shaft 52 through a coupling. A torque wrench 4 is installed below the main shaft 52. A lifting ring 3 is installed below the torque wrench 4. A lifting card 2 is installed below the lifting ring 3. A drill pipe 1 is installed below the lifting card 2.

[0023] The traveling carriage 9 is provided with a through hole 91 , and the top of the lifting ring 8 is integrally provided with a hook 81 , and the hook 81 passes through the through hole 91 and is hung on the traveling carriage 9 .

[0024] The locking mechanism comprises a U-shaped block 11 welded on the traveling block 9 , a limit block 12 is mounted on the U-shaped block 11 via bolts 13 , and the bottom of the limit block 12 abuts against the hook 81 .

[0025] A slide groove 111 is formed on the inner wall of the U-shaped block 11, and sliders 121 are welded at both ends of the limit block 12. The inner wall of the slide groove 111 is slidably connected to the sliders 121, so that when the top drive main shaft is elastically moved upward along the vertical direction to protect the joint and the drill pipe shackle at the lower end of the top drive main shaft, the limit block 12 can limit the rise of the hook 81 to prevent the lifting ring from elastically moving upward and causing separation from the traveling block hook.

[0026] During specific use, after the hook 81 at the top of the lifting ring 8 passes through the through hole 91 on the traveling block 9 and is hung on the traveling block 9, the limit block 12 is slid onto the U-shaped block 11, and the limit block 12 and the U-shaped block 11 are fixed by using the bolt 13, and the limit block 12 is used to resist the hook 81; when the top drive main shaft is protected by the joint and the drill pipe at the lower end, and the top drive main shaft moves upward elastically in the vertical direction, the limit block 12 limits the rise of the hook 81 to prevent the lifting ring from moving upward elastically and causing it to separate from the traveling block hook. Example 2

[0027] See attached Figure 5, which is different from Example 1, a barb block 811 is welded on the top of the hook 81, and the limit block 12 abuts against the hook 81 and is located between the right side wall and the barb block 811, further enhancing the anti-detachment effect.

[0028] During specific use, after the hook 81 at the top of the lifting ring 8 passes through the through hole 91 on the traveling block 9 and is hung on the traveling block 9, the limit block 12 is slid onto the U-shaped block 11, and the limit block 12 and the U-shaped block 11 are fixed by using the bolt 13, and the limit block 12 is used to resist the hook 81; when the top drive main shaft is protected by the joint and the drill pipe at the lower end, and the top drive main shaft moves upward elastically in the vertical direction, the limit block 12 limits the rise of the hook 81 to prevent the lifting ring from moving upward elastically and causing it to separate from the traveling block hook.
