[0032] Embodiment 2

[0033] The main difference from the first embodiment is:

[0034] A pipe bending device for ship maintenance, the rotating assembly 5 includes a rotating groove 51 opened on the surface of the pipe bending column 2, the surface of the driving rod 44 has a columnar protrusion, the surface of the driving rod 44 is slidably connected to the inner surface of the rotating groove 51, a rotating spring 52 is fixedly connected between the driving rod 44 and the rotating groove 51, the driving assembly 6 includes a driving column 61 fixed on the surface of the driving block 42, a driving groove 62 is opened inside the driving rod 44, the surface of the driving column 61 is slidably connected to the inner surface of the driving groove 62, the driving groove 62 on the upper part of the driving rod 44 is rectangular, and the lower part is annular. When the driving The surface of the column 61 contacts the upper part of the driving groove 62 and the two can move synchronously. The driving column 61 and the driving groove 62 contact the driving block 42 below and can slide out of the interior of the driving rod 44. The limiting assembly 7 includes a limiting groove 71 opened on the surface of the bending platform 1. The surface of the adjusting block 45 is slidably connected with the inner surface of the limiting groove 71. There is a rough protrusion on the surface of the adjusting block 45. The upper surface of the limiting groove 71 is rough. The protrusion of the adjusting block 45 slides upward and can contact the inner surface of the limiting groove 71. The inner sliding connection of the limiting groove 71 is the limiting block 73. The inner sliding connection of the bending platform 1 is limited The surface of the limiting rod 74 is rotatably connected to the transfer shaft 75, and the surface of the limiting block 73 is rotatably connected to the transfer rod 76. A rotating assembly 72 is provided between the transfer rod 76 and the tube bending platform 1 to limit the rotation.

The rotating assembly 72 includes a rotating shaft 721 fixed on the surface of the transfer rod 76. A rotating ring 722 is fixedly connected to the inside of the tube bending platform 1. The surface of the rotating shaft 721 is slidably connected to the inner surface of the rotating ring 722. A limit block 73 that can move up and down is arranged inside the limit groove 71 opened on the surface and on which the adjusting block 45 slides with its inner surface.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] During operation, firstly, the guide block 3 of suitable curvature is fixed on the surface of the bending column 2 and the mortgage block by the screw rod, and then the limit rod 74 is pulled upward, and the transfer shaft 75 and the transfer rod 76 that slide upward of the limit rod 74 rotate. The rotation of the transfer rod 76 causes the limit block 73 to move downward. At this time, the adjustment block 45 moves downward under the action of gravity. The adjustment block 45 is rotated to a suitable position, and the limit rod 74 is pressed downward again, so that the limit block 73 drives the adjustment block 45 to move upward, and the position of the adjustment block 45 is limited by friction. The pipe is fixed on the surface of the bending column 2, and then the motor is started. The start of the motor will drive the ratchet 4 1 rotates, and when the ratchet 41 rotates, it drives the bending column 2 to rotate through the driving rod 44. The rotation of the bending column 2 causes the pipe to bend, and the rotation of the bending column 2 drives the internal driving block 42 to rotate. When the surface of the driving block 42 contacts the surface of the adjusting block 45, the driving block 42 moves downward under the action of the adjusting block 45, and then the driving column 61 on the surface of the driving block 42 contacts the inner surface of the annular driving groove 62. At this time, the driving rod 44 will not drive the driving block 42 to move. At this time, the bending column 2 no longer rotates, and the motor is turned off in time. The driving rod 44 will restore its relative position with the driving block 42 under the action of the spring.
