Description

Technical Field

[0001] The invention relates to the technical field of cranes, in particular to an intelligent and automatically rotating European-style hook group. Background Art

[0002] The lifting hook is an indispensable part of mechanical lifting in industrial production, bridge construction and transportation. At present, when a crane lifts a heavy object, it relies on a hook group and a rope to connect the heavy object. If the heavy object needs to be rotated at any angle of 0-360 degrees or the heavy object needs to be accurately rotated at a certain angle, ordinary cranes can only rely on manpower or ordinary rotating hooks to rotate in an inching manner; such as the automatic rotating hook group used in a crane proposed in the existing patent document CN210340085U, the hook group can be rotated by manpower, but when the lifting weight is large, manual or ordinary rotating hooks are very difficult to operate, and there are certain safety hazards.

[0003] To solve this problem, the prior art patent document CN218909601U proposes an electric rotating hook group. This type of hook can use a motor to drive the hook to rotate to achieve the rotation of the hook. However, in the application of heavy-weight cranes, due to the large weight of the lifting, the rotating parts of the hook will produce severe friction under the gravity of the heavy weight, and mechanical debris will be generated after the severe friction. These mechanical debris are distributed in the rotating parts, which will aggravate the wear of the rotating parts. Therefore, the rotating parts of heavy-weight hook groups are often damaged. At the same time, although the existing hook groups are provided with a structure that can prevent unhooking, they cannot achieve automatic rope removal. Therefore, manual rope removal is still required. In response to the above problems, we provide an intelligent automatic rotating European hook group to solve the above-mentioned problems.

After the lifting cargo arrives at the designated position, the cargo is put down, and the mountain-shaped hook 12 loses the weight of the cargo. The convex block 9 will reset under the action of the reset spring 8 due to the downward pressure of the force. During the reset, since the T-shaped lock frame 508 is in a locked state, the limit slide frame 501 drops when the convex block 9 resets, and the double-sided toothed plate 503 remains stationary in place under the action of the T-shaped lock frame 508, and the tension spring 504 is stretched at this time. After the locking assembly is unlocked, the double-sided toothed plate 503 moves downward under the action of the tension spring 504, thereby driving the gear 502 to rotate, and the rotation of the gear 502 drives the T-shaped lock frame 508 to open.

When unlocking is required, the electromagnet 513 will attract the iron slider 511, and the inclined locking block 509 will be retracted into the inner slide groove 512 to achieve unlocking.

Protective shells 303 are also installed on both sides of the mountain-shaped hook 12. An avoidance slot 307 is opened in the middle of the trapezoidal block 306; when it is necessary to take the rope out of the mountain-shaped hook 12, the electric push rod 301 can be used to drive the side slider 305 to move upward, and the upward movement of the side slider 305 drives the trapezoidal block 306 to move, and the upward movement of the trapezoidal block 306 can push the rope in the mountain-shaped hook 12 upward and get out of the mountain-shaped hook 12 along the inclined surface.

[0039] The working principle of the present invention is: when working, it is hung on the mountain-shaped hook 12, and then lifted. When lifting, the reset spring 8 is stressed, so that the convex block 9 and the top plate 14 are close to each other, and the convex block 9 moves upward relative to the mountain-shaped hook 12. The upward movement of the convex block 9 will drive the limit slide frame 501 to move upward, and the upward movement of the limit slide frame 501 will drive the limit block 507, and the limit block 507 drives the double-sided toothed plate 503 to move upward synchronously, and the movement of the double-sided toothed plate 503 can drive the gear 502 to rotate, and the rotation of the gear 502 can drive the T-shaped lock frame 508 to rotate. , and then the T-shaped lock frame 508 is stuck into the grooves on both sides of the mountain-shaped hook 12, and then the inclined locking block 509 is retracted into the inner slide groove 512 under the action of the inclined surface, and then pops out when it reaches the locking groove 505, so as to achieve the locking of the state of the T-shaped lock frame 508 to prevent the rope from being unhooked; when it is necessary to rotate the mountain-shaped hook 12, the servo motor 201 drives the internal transmission components of the worm gear reducer 202 to operate, and then the output shaft of the worm gear reducer 202 drives the first gear 203 to rotate, and the rotation of the first gear 203 can drive the second gear 204 to rotate, and the second gear The rotation of wheel 204 can drive the suspension rod 7 to rotate, and the suspension rod 7 drives the mountain-shaped hook 12 to rotate. After the hoisted cargo reaches the designated position, the cargo is put down. The mountain-shaped hook 12 loses the downward pressure of the cargo's gravity, and the convex block 9 is reset under the action of the reset spring 8. During the reset, since the T-shaped lock frame 508 is in a locked state, the limit slide frame 501 drops when the convex block 9 is reset, and the double-sided toothed plate 503 remains in place under the action of the T-shaped lock frame 508, and at this time the tension spring 504 is stretched, and then the iron slider 511 is attracted by the electromagnet 513 to move the inclined surface The lock block 509 can be retracted into the inner slide groove 512 to achieve unlocking. After unlocking, the double-sided toothed plate 503 moves downward under the action of the tension spring 504, which can drive the gear 502 to rotate. The rotation of the gear 502 drives the T-shaped lock frame 508 to open. When the rope needs to be taken out from the mountain-shaped hook 12, the electric push rod 301 can be used to drive the side slider 305 to move upward. The upward movement of the side slider 305 drives the trapezoidal block 306 to move. The upward movement of the trapezoidal block 306 can push the rope in the mountain-shaped hook 12 upward and remove it from the mountain-shaped hook 12 along the inclined surface, thereby realizing the automatic rope-removing function.
