SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an automatic opening device of pressure-bearing type lifting hook in order to remedy prior art's defect.
The utility model discloses a realize through following technical scheme:
the utility model provides an automatic opening device of bearing type lifting hook, is including mounting panel, connecting rod one, connecting rod two, locking cylinder and lifting hook, the one end of lifting hook be the horizontal plate, the other end is the hang plate, locking cylinder fixed mounting on the mounting panel, the upper end of connecting rod one be connected with the mounting panel through axle one, a connecting rod upper end rotates round axle one, the lower extreme of connecting rod one is articulated with the output rod tip of locking cylinder and the upper end of connecting rod two respectively, the lower extreme of connecting rod two is articulated with the tip of the horizontal plate of lifting hook, the horizontal plate of lifting hook still is connected with the mounting panel through axle two, the horizontal plate rotates round axle two.
And a limiting column is fixed on the mounting plate on the side surface of the first connecting rod.
The mounting plate is also fixedly provided with a vertical belt blocking plate, and when the lifting hook is opened, the belt blocking plate plays a role in blocking the lifting belt, so that the lifting belt is effectively separated from the lifting hook.
The mounting panel on install the anticreep and take the pole, the anticreep takes the pole to be connected with the mounting panel through axle three, still is connected with the extension spring between the upper end of anticreep area pole and mounting panel, the extension spring is pulling the anticreep and is taking the pole to rotate round axle three, the lower extreme of anticreep area pole is blocked by the tip of the hang plate of lifting hook. When the hanging strip is hung on the lifting hook, the anti-falling strip rod props against the end part of the lifting hook under the condition that the lifting hook is not opened, and the hanging strip is prevented from falling off.
The locking cylinder is pulled back, the first connecting rod and the second connecting rod are positioned on the same straight line under the action of the locking cylinder and are positioned at dead points on the four-connecting-rod structure, the lifting hook is in a horizontal state, the hanging strip is hung on the lifting hook, the lifting hook is pulled by the hanging strip, but the lifting hook cannot rotate due to the fact that the first connecting rod and the second connecting rod are positioned at the structural dead points, and therefore the pulling force transmitted by the hanging strip is borne;
under the condition that the hanging strip bears the tension, the locking cylinder is pushed out, a certain angle is formed between the first connecting rod and the second connecting rod, the first connecting rod and the second connecting rod are separated from a dead point, the lifting hook is pulled by the hanging strip to rotate rapidly, the lifting hook is in an inclined state, the hanging strip slides off the lifting hook, and the hanging strip is automatically separated from the lifting hook;
the mounting plate is a fixed plate for mounting rotating shafts such as a cylinder, a first connecting rod, a second connecting rod, a lifting hook and the like.
The belt blocking plate is used for ensuring the effective separation of the hanging belt and the lifting hook when the hanging belt is opened;
the anti-drop band rod is tightly pressed on the lifting hook under the action of the tension spring, so that the hanging strip is prevented from being accidentally separated.
The utility model has the advantages that: the utility model discloses a fine control lifting hook of locking cylinder and connecting rod structure is automatic to be opened, and simple structure is reasonable, need not operating personnel own manual unhook, convenient operation, and work efficiency is high, and the security performance is good.

Detailed Description
As shown in fig. 1, an automatic opening device of pressure-bearing type lifting hook, including mounting panel 1, connecting rod 2, two 3 of connecting rod, locking cylinder 4 and lifting hook 5, the one end of lifting hook 5 be the horizontal plate, the other end is the hang plate, 4 fixed mounting of locking cylinder on mounting panel 1, the upper end of connecting rod 2 be connected with mounting panel 1 through axle 6, 2 upper ends of connecting rod rotate round axle 6, the lower extreme of connecting rod 2 is articulated with the output rod tip of locking cylinder 4 and the upper end of two 3 of connecting rod respectively, the lower extreme of two 3 of connecting rod is articulated with the tip of the horizontal plate of lifting hook 5, the horizontal plate of lifting hook 5 still is connected with mounting panel 1 through axle two 7, the horizontal plate rotates round axle two 7.
And a limiting column 8 is fixed on the mounting plate 1 at the side of the first connecting rod 2.
And a vertical belt blocking plate 9 is further fixed on the mounting plate 1, and when the lifting hook 5 is opened, the belt blocking plate 9 plays a role of blocking the lifting belt, so that the lifting belt 10 is effectively separated from the lifting hook 5.
Mounting panel 1 on install anticreep band pole 13, anticreep band pole 13 is connected with mounting panel 1 through three 11 axles, still is connected with extension spring 12 between the upper end of anticreep band pole 13 and mounting panel 1, extension spring 12 is drawing anticreep band pole 13 and is rotating round three 11 axles, the lower extreme of anticreep band pole 13 is blocked by the tip of the hang plate of lifting hook 5. When the hanging strip 10 is hung on the hook 5 and the hook 5 is not opened, the falling-off preventing band 13 is pressed against the end of the hook 5 to prevent the hanging strip 10 from falling off.
