Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

Referring to fig. 1 to 2, a rotary spreader includes a hanger 10, and the hanger 10 is provided in an inverted U-shaped configuration. The device further comprises a first clamping device 20a and a second clamping device 20b which are arranged on the hanger 10 and used for clamping and rotating the coil 1, and a locking driving device 30 which is arranged on the hanger 10 and used for driving the first clamping device 20a and the second clamping device 20b to work, wherein the locking driving device 30 is preferably a locking air cylinder, and the locking air cylinder 30 is hung upside down on the hanger 10. The hanger 10 is provided with a hanging ring 11 matched with the travelling crane, and the hanger 10 is also provided with a connecting block 12 matched with a first clamping device 20a and a second clamping device 20 b.

The first clamping device 20a comprises a first boom 21a disposed on the hanger 10 and engaged with the connecting block 12, a first locking wheel 22a disposed at one end 211a of the first boom 21a and engaged with the locking driving device 30, and a first clamp plate 23a rotatably disposed at the other end 212a of the first boom 21a and used for clamping the coil 1, wherein the first clamp plate 23a is connected with a crank 25a through a rotating shaft 24 a. The first clamping plate 23a is arranged in an arc structure. Specifically, the rotating shaft 24a is disposed in a groove of the first boom, and has one end connected to the first clamp plate 23a and the other end connected to the crank 25 a.

The second clamping device 20b comprises a second boom 21b disposed on the hanger 10 and cooperating with the connecting block 12, a second locking guide 22b disposed at one end 211b of the second boom 21b and cooperating with the locking driving device 30, and a second clamping plate 23b rotatably disposed at the other end 212b of the second boom 21b and used for clamping the coil 1. The second clamping plate 23b is arranged in an arc structure. Specifically, the second clamp plate 23b is connected to a rotating shaft 24b provided in the second boom 21 b.

The working principle of the invention is as follows:

when the lifting ring 11 is hung on a travelling crane during working, the locking cylinder 30 is in a withdrawing state, the first guide wheel 22a and the second guide wheel 22b are in a close state, when the travelling crane is operated to a working position (material coiling), the locking cylinder 30 extends out, the first guide wheel 22a and the second guide wheel 22b are separated, the first clamping plate 23a and the second clamping plate 23b of the first suspension arm 21a and the second suspension arm 21a are driven to be attached to the outer surface of the coil pipe 1, the first clamping plate 23a and the second clamping plate 23b clamp the coil pipe 1 tightly, after the coil pipe 1 is clamped tightly, the crank 25a is manually rotated to rotate the coil pipe 1 by 180 degrees so as to achieve the purpose of overturning, and after the overturning is completed, the travelling crane is started to place the coil pipe 1 at a proper position, and then the next coil pipe 1 is overturned.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
