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 FIGS. 1 to 4 , the present utility model provides a technical solution: a crane hook that can quickly lift heavy objects, comprising a hook 1 , a fixing block 2 is fixedly connected to the upper surface of the hook 1 , and the fixing block The upper surface of 2 is clamped with a connector 3, and both sides of the connector 3 are threaded with bolts 13. One side of the bolts 13 is provided with a cross groove, and the number of bolts 13 is four. Rotating the bolts 13 facilitates the connection. The disassembly between the part 3 and the hook 1 is convenient for the staff to repair and replace the hook 1, and the practicability of the device is improved. A pulley 11 is fixedly connected, and the number of pulleys 11 is several. Through the setting of the pulley 11, the device can be connected to the crane through a cable, which is convenient for the hoisting and use of the crane. One end of the hook 1 is fixedly connected with a support frame 5. The support frame The upper surface of 5 is fixedly connected to a limiting device 6, the limiting device 6 includes a limiting block 601, one side of the limiting block 601 is arc-shaped, and the other side is a rectangular plane, and the upper surface of the limiting block 601 is fixedly connected with a support Rod 602, the side of the support rod 602 is fixedly connected with a clamping block 603, the surface of the support rod 602 is sleeved with a return spring 604, one side of the hook 1 is provided with a chute 7, and the hook 1 is slidably connected to an arc through the chute 7 Shaped plate 8, one side of the arcuate plate 8 is fixedly connected to the lower surface of the hook 1, the front of the arcuate plate 8 is provided with a card slot 12, the card slot 12 is matched with the limit block 601, the arcuate plate 8 One end of the spring 9 is fixedly connected with a spring 9, and one end of the spring 9 is fixedly connected with the casing 10. When the steel cable with the heavy object is hung on the surface of the hook 1, the arc plate 8 is pulled to make one end plugged in. With the inside of the support frame 5, when the surface of the support frame 5 contacts the limit block 601, because one side of the limit block 601 is arc-shaped, the limit block 601 moves upward by the return spring 604. When the position block 601 corresponds to the position block 601, the limit block 601 is clamped in the slot 12 by the elastic force of the return spring 604, and the position of the arc plate 8 is fixed, so that the steel cable suspended on the surface of the hook 1 can be fixed. When the lifting hook moves, the steel cable inside is prevented from falling off accidentally. When the crane transports the heavy object to a suitable position through the lifting hook 1, the support rod 602 is pulled upward to make the limit block 601 disengage from the slot 12. Inside, through the elastic force of the spring 9, the arc-shaped plate 8 slides along the chute 7 to the initial position, and through the elastic force of the spring 9 itself, the reset arc-shaped plate 8 can be fixed to a certain extent. , compared with the traditional device, the operation process of the staff is simplified, and the hoisting efficiency of the hook 1 is improved.

To sum up, the working steps of the crane hook that can quickly lift heavy objects are as follows;

1. Before use, the user snaps the connector 3 into the fixing block 2, turns the bolt 13, connects the protective shell 4 and the hook 1 and other structures to each other, and then connects the pulley 11 to the crane, and then hangs the heavy The rope of the object is hung on the hook 1;

2. The user clamps one end of the arc plate 8 into the slot 12, and through the action of the limiting device 6, the steel cable suspended in the hook 1 can be protected to a certain extent, so that the heavy objects can be protected. Lifting, reducing the possibility of the inner steel cable falling off when the hook 1 moves;

3. After hoisting, the user pulls the support rod 602 on the limiting device 6 to take out the limiting block 601 from the slot 12, and the arc-shaped plate 8 is acted by the elastic force of the spring 9 to make the arc-shaped plate 8 reset.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
