A rotating ring 6 for rotating the vertical pipe to be punched is rotatably arranged inside the cantilever 2. A limiting convex ring 7 is arranged on the top of the rotating ring 6, and a linkage ring 15 is rotatably arranged on the outer wall of the limiting convex ring 7; the linkage ring 15 consists of an inner clamping ring 1501 and an outer clamping ring 1502, and multiple groups of clamping arms 17 for positioning the vertical pipe are movably arranged between the inner clamping ring 1501 and the outer clamping ring 1502; a moving seat 28 is movably arranged at the bottom of the main frame 1, and a rotating outer seat 28 is movably arranged in the middle of the moving seat 28 32 and a rotating inner seat 33. When the rotating ring 6 drives the riser to rotate, the rotating outer seat 32 and the rotating inner seat 33 rotate synchronously; the top of the rotating inner seat 33 is provided with an inner clamping mechanism 36 for fixing the inner wall of the riser; the main frame 1 is also movably provided with a lifting seat 46 located on the inner side of the cantilever 2 in the vertical direction, and a punching cylinder 47 is installed on the outer side of the lifting seat 46, and a drilling rig 48 is movably installed on the inner side of the punching cylinder 47; a collecting box 49 is also fixedly installed on the inner wall of the main frame 1, and a material receiving plate 51 abutting against the outer wall of the riser is movably provided on the top of the collecting box 49, and the material receiving plate 51 is located below the drilling rig 48.

[0035] In this embodiment: the barrel rotary punching device is mainly divided into three parts: the main frame 1, the moving seat 28 and the rotating ring 6 structure. When the device is in use, the vertical pipe is first placed on the rotating outer seat 32 on the moving seat 28 through the external lifting equipment, and is located on the top of the rotating outer seat 32. Then the clamping cylinder 38 is turned on, and the multiple groups of clamping arc plates 42 swing outward and clamp the inner wall of the vertical pipe. Then the conveying motor 26 is started, and the moving seat 28 drives the vertical pipe through the clamping outer mouth 5, the clamping inner mouth 8 and the clamping notch 16 to enter the interior of the rotating ring 6. Then the clamping motor 22 is started again. When the clamping motor 22 drives the linkage ring 15 to rotate counterclockwise, the multiple groups of clamping arms 17 swing inward relative to the cantilever 2 to clamp and fix the vertical pipe. Before punching, the driving motor 58 is started to drive the protective cover 56 to rotate and block the annular plate 54.

[0036] See attached Figure 2 and attached Figure 8 A rotating cavity 3 is vertically penetrated on the cantilever 2, and a rotating ring 6 is rotatably arranged in the rotating cavity 3. A driving cavity 4 is penetrated horizontally on the cantilever 2; a clamping outer opening 5 connected with the rotating cavity 3 is provided on the cantilever 2, and a clamping inner opening 8 cooperating with the clamping outer opening 5 is provided on the rotating ring 6.

[0037] In this embodiment, in order to facilitate the clamping of the vertical tube from the side, a clamping outer opening 5 and a clamping inner opening 8 are provided to cooperate with each other. In order to ensure smooth insertion of the parts, the clamping notch 16 is flush with the clamping outer opening 5 in the initial state when the vertical tube is not clamped.

[0038] See attached Fig. 9 and attached Fig.11 In the driving cavity 4, active rollers 10 are movably installed on both sides of the rotating ring 6, and driven rollers 11 are movably installed between the active rollers 10 and close to the rotating ring 6. A rotating motor 12 is installed on the outer wall of the cantilever 2, and a driving roller 9 located in the driving cavity 4 is installed at the output end of the rotating motor 12. A belt 13 for driving the rotating ring 6 to rotate is connected between the driving roller 9, the active roller 10 and the driven roller 11.

[0039] In this embodiment: driven by the rotating motor 12, the active roller 10 and the driven roller 11 rotate in conjunction. Since the outer wall of the belt 13 abuts against the rotating ring 6, and the angle between the active rollers 10 is greater than the clamping inner mouth 8, the rotating ring 6 will drive the outer linkage ring 15 to rotate freely.

[0040] See attached Fig.11 , limiting rollers 14 are movably installed between the driving chambers 4 and located on both sides of the clamping outer opening 5.

[0041] In this embodiment: when the rotating ring 6 rotates, since the angle between the active rollers 10 on both sides is less than 180 degrees, in order to ensure the smooth rotation of the rotating ring 6 and avoid accidental falling off, a symmetrical limiting roller 14 structure is designed.

A swing block 21 is movably installed on the top of the boss 20. A clamping motor 22 is also installed on the limiting convex ring 7. A threaded rod 60 is provided at the output end of the clamping motor 22. The threaded rod 60 is movably connected to the swing block 21.

[0043] In this embodiment: when the clamping motor 22 drives the linkage ring 15 to rotate counterclockwise, the multiple clamping arms 17 swing inward relative to the cantilever 2 to clamp and fix the vertical pipe. When the clamping motor 22 drives the linkage ring 15 to rotate clockwise, the multiple clamping arms 17 swing outward relative to the cantilever 2 to unlock the vertical pipe.

A lifting screw 45 is installed at the output end of the lifting motor 44, and a lifting seat 46 is threadedly connected to the lifting screw 45.

[0045] In this embodiment, before clamping the vertical pipe, the vertical pipe needs to be placed on the moving seat 28 by external lifting equipment, and then the vertical pipe is passed through the clamping outer opening 5 and transported into the rotating chamber 3 by the conveying motor 26. During the drilling operation, in order to increase the degree of freedom and perform drilling operations at different positions, a movable lifting seat 46 structure is designed.

[0046] See attached Figure 3 -Attached Figure 4 A through inner clamping cavity 29 is provided in the middle of the moving seat 28, and a positioning groove 30 coaxial with the inner clamping cavity 29 is also provided on the top of the moving seat 28; a bearing 31 is installed in the positioning groove 30, a rotating outer seat 32 is movably installed on the top of the bearing 31, and a rotating inner seat 33 is rotatably arranged at the bottom of the inner clamping cavity 29; the inner clamping mechanism 36 includes a mounting tube 37 installed on the top of the rotating inner seat 33, a clamping cylinder 38 is installed inside the mounting tube 37, a driven swing arm 1 39 and a driven swing arm 2 40 are movably installed on the outer wall of the mounting tube 37, and a clamping arc plate 42 is movably connected to the outer sides of the driven swing arm 1 39 and the driven swing arm 2 40; a plurality of active swing arms 41 are movably connected to the output end of the clamping cylinder 38, and the outer sides of the active swing arms 41 are movably connected to the inner wall of the clamping arc plate 42.

[0047] In this embodiment, in order to quickly locate the bottom of the vertical pipe during installation, a coaxial rotating outer seat 32 and a rotating inner seat 33 are designed. When the rotating ring 6 drives the vertical pipe to rotate, the bottom of the vertical pipe is guaranteed to rotate freely relative to the moving seat 28. This design is suitable for heavy cylinders. When the vertical pipe is installed on the rotating outer seat 32, the inner clamping mechanism 36 is located inside the vertical pipe, and then the clamping cylinder 38 is turned on.
