The specific embodiment is as follows:
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-4, the present utility model provides a technical solution for a crane hook limiting frame:
At present, in a production workshop for smelting alloy, when a ladle is ready to be hoisted, traditional hoisting equipment comprises a lifting appliance 1 and a chain hook 2;
The lifting appliance 1 comprises a cross beam 1.1, a first lifting lug 1.2 and two first lifting hooks 1.3; the middle part of the upper surface of the cross beam 1.1 is fixed with a first lifting lug 1.2, and two ends of the lower surface of the cross beam 1.1 are respectively hinged with a first lifting hook 1.3. The chain hook 2 comprises two chain links 2.1, a second lifting lug 2.2 and two second lifting hooks 2.3; one end of each of the two chains 2.1 is connected through a second lifting lug 2.2, and the other ends of the two chains 2.1 are respectively hinged with a second lifting hook 2.3. Usually, a first lifting lug 1.2 on the lifting appliance 1 and a second lifting lug on the chain hook 2 are respectively lifted through a crown block, and a lifting device (belonging to the prior art and not described here) capable of lifting is arranged on the crown block, and is operated through manual remote control;
In order to solve the problem that the two chains 2.1 are not independent to shake and twine in the moving process at present; and the two second hooks 2.3 on the chain hook 2 can collide with the surface of the lifting appliance 1 or the ladle 6 from time to time, so that a loud sound is generated; and the improvement and optimization are determined on the basis of the existing structure, and the existing problems are solved.
The overhead travelling crane lifting hook limiting frame comprises two U-shaped connecting pieces 3, a limiting plate 4 and two connecting rods 5; the two U-shaped connecting pieces 3 are inserted into the upper surfaces of the two sides of the cross beam 1.1 and are fixed through bolts, one ends of connecting rods 5 are hinged to the vertical surfaces of the two U-shaped connecting pieces 3, which are far away from the same side direction of the mouth of the ladle 6, respectively, the other ends of the two connecting rods 5 and the vertical surface of one side of the limiting plate 4 are fixed through hinging, and the two connecting rods 5 are symmetrically arranged in an eight-shaped structure, so that the limiting plate 4 is fixed relative to the lifting appliance 1. Two through holes 4.1 for penetrating the chain are symmetrically formed in the upper surface of the limiting plate 4, the two chains 2.1 respectively slide through the corresponding through holes 4.1, and the top ends of the two second lifting hooks 2.3 cannot penetrate through the through holes 4.1. The rubber layer 4.2 is fixedly adhered to the inner wall of the through hole 4.1, so that the sound of the chain 2.1 when sliding in the through hole 4.1 is reduced; a connecting plate 7 is fixedly arranged between the two second lifting hooks 2.3, and the problem that the chain hooks 2 are wound in the moving process can be greatly reduced by combining the limiting positions of the upper part and the lower part of the two through holes 4.1 through the connecting plate 7.
The working principle is as follows: when the lifting device is used, the two second lifting hooks 2.3 on the chain hook 2 are lifted to the lower surface of the limiting plate 4, so that the two second lifting hooks 2.3 on the chain hook are prevented from colliding with the surface of the lifting appliance 1 or the ladle 6, and sound is generated; simultaneously, the two chains 2.1 in the moving process are kept stable and stand relatively, so that the occurrence of shaking is reduced, and the danger is reduced.
Then the two first hooks 1.3 on the lifting appliance 1 are hooked on the two lifting columns 6.1 on the ladle 6, then the crane is controlled to move, when the ladle is moved to the preparation area to be cast, the two second hooks 2.3 on the chain hooks 2 are lowered and hooked on the two lifting rings 6.2 on the ladle 6, and then the pouring casting process of the ladle 6 is carried out.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
