Detailed Description

The first embodiment of the application is as follows:

referring to fig. 1, fig. 1 is a schematic structural diagram of a spreader of an anti-swing crane according to a first embodiment of the present utility model.

The utility model provides a lifting appliance of an anti-swing crane, which comprises a lifting mechanism 101, a lifting hook rigid arm 102 and an extension mechanism 103, wherein the extension mechanism 103 comprises a driving assembly 104 and an extension plate 105, and the driving assembly 104 comprises a motor 106, a screw 107, an adapter ring 108, a limiting block 109 and two buffer cushions 110. The problem that the fixing effect of the existing crane on the bulky goods is poor is solved through the scheme, and it can be understood that the scheme can be used in a scene of hoisting the bulky goods.

For this embodiment, the lifting hook rigid arm 102 is disposed on one side of the lifting mechanism 101, the driving assembly 104 is disposed on an inner side wall of the lifting hook rigid arm 102, and the extension plate 105 is slidably connected with the lifting hook rigid arm 102 and is connected with the driving assembly 104. The lifting mechanism 101 comprises a cross beam, a lifting mechanism arranged on the cross beam and a rigid hanging beam connected with the lifting mechanism, wherein the rigid hanging beam comprises two pairs of rigid supports arranged at intervals, a trabecula parallel to the end face of the cross beam, the rigid arms 102 of the lifting hook are connected with two ends of the trabecula, and the rigid supports are arranged at the lower end of the cross beam. Two movable pulleys are arranged on the trabecula at intervals, two guide wheels are arranged on the lifting hook rigid arm 102 at intervals, steel wire ropes are respectively arranged on the movable pulleys, and the steel wire ropes are connected with the lifting mechanism. The lifting mechanism 101 clamps the goods through the lifting hook rigid arm 102, when the volume of the goods is larger, the driving component 104 drives the extension plate 105 slides out from the lifting hook rigid arm 102, the contact area with the bottom of the goods is increased, the stability of the goods fixation is improved, and the problem that the fixing effect of the existing crane on the large-volume goods is poor is solved.
