Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Please refer to FIG. 1 to FIG. 4 , the present utility model provides a technical solution: an anti-dropping double hook of a crane, comprising a fixing ring 1 , a rectangular block 10 is fixedly connected to the upper surface of the fixing ring 1 , and the upper surface of the rectangular block 10 is fixedly connected. A lifting ring 11 is fixedly connected. The setting of the lifting ring 11 facilitates the connection of the device with the crane. Both sides of the front of the fixed ring 1 are fixedly connected with movable blocks 2 through bearings. The number of the movable blocks 2 is two, and the two movable blocks 2 are all U-shaped, wherein a first steel cable 3 is fixedly connected to the lower surface of one movable block 2, and a second steel cable 4 is fixedly connected to the lower surface of the other movable block 2, and the length of the first steel cable 3 is less than The length of the second steel cable 4, when the first hook 6 and the second hook 8 hang ropes to hoist the goods, the first hook 6 and the first steel cable 3 will be stressed, if the first steel cable 3 accidentally When a break occurs, the cargo can be supported and suspended through the second hook 8 and the second steel cable 4 to prevent the cargo from falling to the ground and causing casualties. The first steel cable 3 and the second steel cable 4 are made of high carbon steel. Made of steel material, the lower surface of the first steel cable 3 is fixedly connected with a first connecting piece 5, the interior of the first connecting piece 5 is fixedly connected with a first hook 6, and the lower surface of the second steel cable 4 is fixedly connected with a first hook 6. Two connecting pieces 7, the inside of the second connecting piece 7 is fixedly connected with a second hook 8, the inner bottom walls of the first hook 6 and the second hook 8 are both provided with a groove 12, and the inside of the groove 12 is provided with a groove 12. The anti-skid cushion, through the setting of the groove 12, facilitates the placement of the rope when the goods are suspended. The inner side walls of the first hook 6 and the second hook 8 are provided with a card groove 13, and the card groove 13 is suitable for the card block 9. Equipped, the inner top walls of the first hook 6 and the second hook 8 are fixedly connected with a block 9 through a spring hinge, and the rope hanging on the goods is sleeved on the inside of the first hook 6 and the second hook 8 to open Then the clamping block 9 is clamped in the clamping groove 13 by the elastic force of the spring hinge, so that the rope can be protected to a certain extent, and the rope can be prevented from being damaged during the hoisting operation.
