[0026] like Figures 1 to 6 As shown, the utility model provides a lifting mechanism for cement pipe manufacturing, comprising:

[0027] A rectangular plate 1, a fixed plate 2 is fixedly connected to the bottom of the rectangular plate 1, a circular shaft 3 is fixedly sleeved inside the fixed plate 2, the number of the circular shafts 3 is two, the outer surfaces of the two circular shafts 3 are movably sleeved with a first clamping block 4 and a second clamping block 5, the number of the first clamping block 4 and the second clamping block 5 are both two, the outer surfaces of the two first clamping blocks 4 are movably connected to the outer surfaces of the two second clamping blocks 5, and the outer sides of the two first clamping blocks 4 and the two second clamping blocks 5 are movably connected to the inner side of the fixed plate 2;

[0028] A clamping mechanism, which is arranged on the top of the rectangular plate 1;

[0029] Among them, the clamping mechanism includes a pneumatic cylinder 6, the number of which is two, and the two pneumatic cylinders 6 are fixedly installed on both sides of the top of the rectangular plate 1. The bottoms of the two pneumatic cylinders 6 penetrate the rectangular plate 1 and extend to the bottom of the rectangular plate 1 and are fixedly connected with a connecting plate 7. The outer side of the connecting plate 7 is movably connected to the inner side of the fixed plate 2. The left and right sides of the bottom of the connecting plate 7 are hinged with rotating rods 8. The number of rotating rods 8 is four, and the other ends of the four rotating rods 8 are respectively hinged to the inner sides of the two first clamps 4 and the two second clamps 5. The first clamp 4 and the second clamp 5 rotate around the circular axis 3 to clamp the cement pipe.

[0030] When the two pneumatic cylinders 6 are in operation, they will drive the two connecting plates 7 to move upward, thereby causing the four rotating rods 8 to rotate and drive the two first clamping blocks 4 and the two second clamping blocks 5 to rotate around the circular shaft 3, thereby achieving the purpose of clamping and fixing the cement pipe.

[0031] A cylindrical block 9 is fixedly connected to the middle of the top end of the rectangular plate 1 , and a hook 10 is fixedly connected to the top of the cylindrical block 9 .

[0032] The design of the hook 10 enables the lifting device to lift the rectangular plate 1 as a whole through the hook 10 .

[0033] Among them, a limiting groove 11 is opened on the front side of the hook 10, and the inner surface of the limiting groove 11 is movably connected with a rotating block 12, and the front side of the rotating block 12 is fixedly connected with a round rod 13, and the outer surface of the round rod 13 is movably connected with the inner surface of the limiting groove 11, and the front side of the round rod 13 passes through the limiting groove 11 and extends to the outside of the limiting groove 11.

[0034] By pulling the round rod 13 to rotate, the rotating block 12 can be driven to rotate.

[0035] A side cavity 14 is provided on the right side of the hook 10 , a spring 15 is fixedly connected to the bottom of the side cavity 14 , a pull rod 16 is fixedly connected to the other end of the spring 15 , and an outer surface of the pull rod 16 is movably connected to the inner surface of the side cavity 14 .

[0036] Pulling the pull rod 16 downward will compress the spring 15 to move downward.

[0037] The top of the pull rod 16 is fixedly connected with a vertical block 17 , and the outer surface of the vertical block 17 is movably connected to the inner surface of the side cavity 14 .

[0038] The vertical block 17 moves downward, so that the rotating block 12 can be rotated and inserted into the interior of the hook 10 .

[0039] The outer surface of the vertical block 17 is smooth, and the appearance of the vertical block 17 is rectangular.

[0040] Such a design allows the vertical block 17 to move more smoothly inside the side cavity 14 .

[0041] There are four fixing plates 2 , the four fixing plates 2 have the same size, and the four fixing plates 2 are symmetrical with respect to the center of the rectangular plate 1 .

[0042] The design of four fixing plates 2 has a good fixing effect on the two circular shafts 3 .

[0043] The working principle and use process of this utility model:

[0044] When clamping the cement pipe, starting the two pneumatic cylinders 6 will drive the two connecting plates 7 to move upward, thereby causing the four rotating rods 8 to rotate and drive the two first clamping blocks 4 and the two second clamping blocks 5 to rotate around the circular shaft 3, thereby achieving the purpose of clamping and fixing the cement pipe and avoiding damage to the cement pipe mouth due to the influence of the clamp.

[0045] When lifting the cement pipe, first put the ring on the outer surface of the hook 10, and then pull the pull rod 16 downward, which will squeeze the spring 15 downward and drive the vertical block 17 downward. When the vertical block 17 is completely moved to the inside of the side cavity 14, the round rod 13 is pulled to rotate, which will drive the rotating block 12 to rotate and insert into the inside of the hook 10, and then release the pull rod 16. Due to the elastic recovery effect of the spring 15, the vertical block 17 moves upward and inserts into the inside of the rotating block 12 to fix it, thereby realizing the closed protection of the hook 10 and avoiding accidents caused by the ring falling off the outer surface of the hook 10.
