[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a reset mechanism, etc., and when the shell needs to be hoisted, the operator uses KBK to drop the hoist, and under the action of the first tension spring and the second tension spring, the right plate and the left plate are rotated and stretched along the second half-threaded bolt, then one of the claws is clamped on the outer circle of the shell, and the other claw is aligned with the outer circle of the shell, and the shell reinforcement rib is clamped in the slot, and then the hoist is moved upward by KBK, at this time, the right plate and the left plate can be driven to rotate and shrink along the second half-threaded bolt, and at the same time, the first tension spring and the second tension spring are stretched, and the two claws are aligned with the shell. The outer circles are against each other to realize the clamping operation. Then, the shell is pushed to flip by hand, and at the same time, the claw and the first half threaded bolt are driven to rotate. Then the hanger is dropped through KBK, so that the shell is placed in the tooling for processing. The shell can be placed in the tooling accurately and quickly. After the shell is put down, the right plate and the left plate can be rotated and stretched open under the action of the first tension spring and the second tension spring to realize automatic disengagement, so as to facilitate the separation of the hanger from the shell. It is more convenient and quick to use, reduces the labor intensity of the operator, can improve the processing efficiency, and is safer and more reliable.

[0021] The present invention provides a speed limiting mechanism, etc., so that when the reducing shell is flipped, the claw and the first half threaded bolt can be driven to rotate. At this time, under the action of the fourth spring, the friction plate can be abutted against the side wall of the first half threaded bolt, and the rotation of the first half threaded bolt can be limited, so that the flipping of the reducing shell is more stable and reliable. In addition, by rotating the rocker, the rotation of the rocker drives the rotation of the threaded rod, thereby driving the slider to move along the guide rod, and then driving the first moving block to move. When the friction plate abuts against the side wall of the first half threaded bolt, when the first moving block continues to move, the distance between the first moving block and the connecting block gradually becomes smaller. At the same time, the fourth spring is gradually compressed. At this time, the compression amount of the fourth spring can be determined by observing the scale mark indicated by the pointer, and then the extrusion force of the friction plate on the first half threaded bolt can be adjusted and controlled. The applicability is stronger and the use effect is better.

[0022] The present invention provides a limiting mechanism, etc., which can drive the claw and the first half-threaded bolt to rotate synchronously when the shell is flipped. At this time, the pin can slide out of the first hemispherical groove and slide on the side wall of the first half-threaded bolt. At the same time, the third spring is compressed. After the shell is flipped, when the pin is aligned with the second hemispherical groove, the pin can be inserted into the second hemispherical groove for limiting position under the action of the third spring. This reciprocating process can limit the first half-threaded bolt after the shell is flipped, which is more stable and reliable, avoids the shell from rotating randomly, is more stable and reliable, and can ensure that the flipping angle is more accurate, thereby ensuring the effect of its lifting and flipping.

[0023] The present invention provides a detection mechanism, etc., so that when in use, under the action of the second spring, the ball can always be in contact with the end of the flat washer. When the first nut is loosened, the gap between the flat washer and the rectangular block will become larger. At this time, under the action of the second spring, the disc moves toward the right plate or the left plate. At the same time, the distance change is detected by the distance sensor, and an external alarm is used to alert the operator to perform inspection and maintenance, thereby ensuring the lifting and flipping effect, which is safer and more reliable.

[0043] The moving mechanism includes an L-shaped plate 401 fixedly connected to the side wall of the rectangular block 13, and two symmetrically arranged guide rods 402 are fixedly connected between the L-shaped plate 401 and the rectangular block 13, a slider 403 is sleeved on the side wall of the guide rod 402, and the slider 403 is fixed to the side wall of the first moving block 302, a threaded rod 404 is rotatably connected between the L-shaped plate 401 and the rectangular block 13, and a rocker 405 is fixedly connected to one end of the threaded rod 404, and the slider 403 is threadedly connected to the side wall of the threaded rod 404, and by rotating the rocker 405, the rotation of the rocker 405 drives the rotation of the threaded rod 404, thereby driving the slider 403 to move along the guide rod 402, and then driving the first moving block 302 to move.

[0044] The telescopic mechanism includes a connecting block 501 fixedly connected to the side wall of the friction plate 301, and the side wall of the connecting block 501 is fixedly connected to two symmetrically arranged second T-shaped guide rods 502, the first moving block 302 is sleeved on the side wall of the second T-shaped guide rod 502, and the side wall of each second T-shaped guide rod 502 is sleeved with a fourth spring 503, the top of the connecting block 501 is fixedly connected to a scale plate 504, and the top of the scale plate 504 is provided with a scale mark 505, the top of the first moving block 302 is fixedly connected to a support block 506, and the support block 506 is fixedly connected to the side wall of the second T-shaped guide rod 502. A pointer 507 is fixedly connected to the side wall of block 506. When the friction plate 301 abuts against the side wall of the first half-threaded bolt 18 and the first movable block 302 continues to move, the distance between the first movable block 302 and the connecting block 501 gradually decreases. At the same time, the fourth spring 503 is gradually compressed. At this time, the compression amount of the fourth spring 503 can be determined by observing the scale mark 505 indicated by the pointer 507, thereby adjusting and controlling the squeezing force of the friction plate 301 on the first half-threaded bolt 18, which has stronger applicability and better use effect.

[0045] Working principle: When the shell needs to be hoisted, the operator uses KBK to drop the hoist. Under the action of the first tension spring 1005 and the second tension spring 1006, the right plate 1 and the left plate 11 are rotated and stretched along the second half-threaded bolt 903. Then, one of the claws 14 is clamped on the outer circle of the shell, and the other claw 14 is aligned with the outer circle of the shell, and the shell reinforcement rib is clamped into the slot 16. Then, the hoist is moved upward by KBK. At this time, the right plate 1 and the left plate 11 can be driven to rotate and shrink along the second half-threaded bolt 903. At the same time, the first tension spring 1005 and the second tension spring 1006 are stretched, and the two claws 14 are against the outer circle of the shell to achieve the clamping operation;

[0046] Next, push the shell reduction to flip by hand, and at the same time, drive the claw 14 and the first half threaded bolt 18 to rotate, and then drop the hanger through KBK, so that the shell reduction can be placed in the tooling for processing, and the shell reduction can be accurately and quickly placed in the tooling. After the shell reduction is put down, the right plate 1 and the left plate 11 can rotate and open under the action of the first tension spring 1005 and the second tension spring 1006 to achieve automatic disengagement, so as to facilitate the separation of the hanger from the shell reduction, which is more convenient and quick to use, reduces the labor intensity of the operator, can improve the processing efficiency, and is safer and more reliable;

[0047] When the shell is turned over, the claw 14 and the first half threaded bolt 18 can be driven to rotate. At this time, under the action of the fourth spring 503, the friction plate 301 can be abutted against the side wall of the first half threaded bolt 18, and the rotation of the first half threaded bolt 18 can be limited, so that the turning of the shell is more stable and reliable. In addition, by rotating the rocker 405, the rotation of the rocker 405 drives the rotation of the threaded rod 404, thereby driving the slider 403 to move along the guide rod 402, thereby driving the first half threaded bolt 18 to rotate. The moving block 302 moves, when the friction plate 301 abuts against the side wall of the first half-threaded bolt 18, and when the first moving block 302 continues to move, the distance between the first moving block 302 and the connecting block 501 gradually decreases, and at the same time, the fourth spring 503 is gradually compressed. At this time, by observing the scale mark 505 indicated by the pointer 507, the compression amount of the fourth spring 503 can be determined, and then the extrusion force of the friction plate 301 on the first half-threaded bolt 18 can be adjusted and controlled, which has stronger applicability and better use effect;

[0048] Moreover, when the reducing shell is flipped, the claw 14 and the first half-threaded bolt 18 can be driven to rotate synchronously. At this time, the pin 203 can slide out of the first hemispherical groove 201 and slide on the side wall of the first half-threaded bolt 18. At the same time, the third spring 602 is compressed. After the reducing shell is flipped, when the pin 203 is aligned with the second hemispherical groove 202, under the action of the third spring 602, the pin 203 can be inserted into the second hemispherical groove 202 for limiting. This reciprocating process can limit the first half-threaded bolt 18 after the reducing shell is flipped, which is more stable and reliable, avoids the reducing shell from rotating at will, is more stable and reliable, and can ensure that the flipping angle is more accurate, thereby ensuring the effect of its hoisting and flipping.
