Description

Technical Field

[0003] The technical solution disclosed in the Chinese patent with announcement number CN114148907B is that the traction rope passes through the top of the contact sleeve and the bottom of the rope block and is fixedly connected to the hook rod through a hook. When the device needs to flip the heavy object, the winch drives the winch drum to rotate and tightens the traction rope, thereby lifting one end of the heavy object until the contact sleeves on both sides move downward by the same distance. At this time, the travel block will continue to move in the horizontal direction, resulting in different downward movement distances of the contact sleeves and causing the winch drum to tighten the traction rope again until the heavy object is flipped ninety degrees, thereby ensuring that the device can automatically coordinate the horizontal displacement and vertical displacement of the lifting device during the flipping of the heavy object, and always keep the force of the heavy object on the lifting device in the vertical direction, so that the efficiency of the device is at the highest level.

The winch 6 is arranged on the slide 5, and the winch 6 is connected to the wire rope 7, and the wire rope 7 is connected to the balance board 8. The mounting seat 10 is connected to the bottom of the balance board 8. The mounting seat 10 is provided with a mounting hole opening downward, and the suspension rod of the hook 11 is inserted into the mounting hole and slidably connected to its inner wall.

The cylindrical hole is connected to the mounting hole. The two transverse ends of the U-shaped pin 131 pass through the cylindrical hole and the plug hole 111 along one side of the mounting seat 10 and are inserted into the other side of the mounting seat 10. The wedge-shaped block 133 is inserted into the cross bar of the U-shaped pin 131 and is elastically slidably connected thereto, and the wedge-shaped block 133 automatically pops out after passing through the mounting seat 10. At the same time, its plane is close to the mounting seat 10. The connecting member 13 includes a U-shaped pin 131 and a wedge-shaped block 133. The hook 11 is provided with a plug hole 111, the mounting seat 10 is provided with a cylindrical hole, the cylindrical hole is connected to the mounting hole, the two transverse ends of the U-shaped pin 131 pass through the cylindrical hole and the plug hole 111 along one side of the mounting seat 10 and are inserted to the other side of the mounting seat 10, the wedge-shaped block 133 is inserted into the cross bar of the U-shaped pin 131 and elastically slidably connected therewith, and the wedge-shaped block 133 automatically pops out after passing through the mounting seat 10, and its plane is close to the mounting seat 10. A slide groove 1311 is provided in the cross bar of the U-shaped pin 131, and a side hole 1312 connected to the slide groove 1311 is provided on the cross bar of the U-shaped pin 131.

The slide bars 135 on both sides are respectively inserted into the corresponding side cross bars and connected to the sliders 132 in the corresponding side slide grooves 1311, and a spring 136 is sleeved on the slide bar 135. The two ends of the spring 136 are respectively abutted against the ends of the U-shaped pin 131 and the push plate 134 that are close to each other, and the connecting member 13 slides with the mounting seat 10 and the suspension rod of the hook 11 in the state of releasing the lateral sliding limit, so as to facilitate the replacement of the hook 11.
