Embodiment 1

[0043] Please also refer to Figure 1 to Figure 3 , the present embodiment provides an overturning hoist, which is used to overturn the semi-finished or finished workpiece 600 from horizontal to vertical. The reversing spreader includes a lifting unit 100 , a first tong body 200 , a second tong body 300 , a first force transmission unit 400 and a second force transmission unit 500 .

[0044] The top of the lifting unit 100 is provided with a lifting ring 130, and is hooked together with the hook of the lifting device through the lifting ring 130, and then lifted by the lifting device.

[0045]The first pliers body 200 is dovetail-shaped, and an upper pliers portion 210 is provided at one end thereof. The second pliers body 300 is composed of a lower pliers part 310 and a connecting part 320. The lower pliers part 310 is opposite to the upper pliers part 210. One end of the connecting part 320 is integrally formed with the lower pliers part 310, and the other end is connected ...

Embodiment 2

[0053] Please also refer to Figure 4 to Figure 7 , this embodiment provides an overturning hoist, which is used in conjunction with lifting equipment, and can overturn the semi-finished or finished workpiece 600 from horizontal to vertical. The reversing spreader includes a lifting unit 100 , a first tong body 200 , a second tong body 300 , a first force transmission unit 400 and a second force transmission unit 500 .

[0054] The top of the hoisting unit 100 is provided with a hoisting ring 130 , and the hoisting ring 130 is hooked to a hook of a lifting device during use, and the hoisting device can hoist the hoisting unit 100 .

[0055] The first pliers body 200 is dovetail-shaped, and an upper pliers portion 210 is provided at one end thereof. When in use, the upper jaw 210 is in contact with the upper surface of the workpiece 600 . Due to the existence of positive pressure between the two, there is a certain static friction force between the upper jaw 210 and the workpi...

Abstract

The invention provides a turnover lifting appliance. The turnover lifting appliance comprises a lifting unit, a first clamp body, a second clamp body, a first force transmission unit and a second force transmission unit, wherein an upper clamp part is arranged on the first clamp body; the second clamp body comprises a lower clamp part and a connecting part; the lower clamp part is opposite to the upper clamp part; the connecting part is rotationally connected with the first clamp body; the first force transmission unit and the second force transmission unit are arranged between the lifting unit and the first clamp body; when the lifting unit drags the first clamp body through the first force transmission unit, the first clamp body rotates relative to the connecting part in the first direction; and when the lifting unit drags the second clamp body through the second force transmission unit, the first clamp body rotates relative to the connecting part in the second direction. In the process that the first clamp body rotates relative to the connecting part, the upper clamp part and the lower clamp part which are oppositely arranged get close to each other or get away from each other, opening and closing actions are completed, so that a workpiece is grabbed. The whole structure of the turnover lifting appliance is simple and light, and the turnover lifting appliance can be easily transferred by virtue of hoisting equipment such as a travelling crane, so that the turnover lifting appliance can work in a large range.

Description

technical field [0001] The invention relates to the field of hoisting and hoisting, in particular to an overturning sling. Background technique [0002] In the forging industry, it is sometimes necessary to turn semi-finished or finished workpieces from horizontal to vertical for further processing. For example, in the process of flange forging, the blank is in a horizontal state before punching, and after punching, the blank must be erected so that the reaming horse bar can penetrate, and then the blank is reamed. [0003] At present, the commonly used turning tool is a reclaimer. However, the reclaimer is bulky, difficult to transfer, and can only operate in a small area, which has defects. Contents of the invention [0004] In order to solve the problem that the turning tool in the prior art can only work in a small area, the object of the present invention is to provide a turning spreader. [0005] The present invention provides following technical scheme: [0006]...
