[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Such as Figures 1-3As shown in the figure, the mushroom head sling includes a bracket 1. The front end of the bracket 1 is movably connected to a linkage rod 2. The rear end of the linkage rod 2 is movably connected to a clamping rod 3 near the lower side of the bracket 1. The rear end of the clamping rod 3 is slidably connected to a clamping guide rod 4. The upper end of the clamping guide rod 4 is equipped with a limit telescopic part 5. A sliding groove 6 is formed inside the clamping guide rod 4. A moving rod 7 is slidably connected to the inner side of the sliding groove 6. A limiting clamping rod 8 is fixedly connected to the front end of the clamping guide rod 4 near one side of the clamping rod 3. An activity shaft 10 is movably connected inside the bracket 1, and a connecting shaft 11 is movably connected inside the linkage rod 2.
[0021] In this embodiment, there are multiple groups of linkage rods 2, and every two groups of linkage rods 2 are assembled together through a connecting shaft 11. The shape of the clamping rod 3 is L-shaped. The moving rod 7 penetrates through the inside of the clamping rod 3, and the moving rod 7 is movably connected to the clamping rod 3. The moving rod 7 penetrates through the inside of the linkage rod 2 near the lower side of the connecting shaft 11, and the moving rod 7 is movably connected to the linkage rod 2. There are multiple groups of clamping rods 3, and there are two groups of limiting clamping rods 8. The two groups of limiting clamping rods 8 are located at the front and rear ends of the clamping guide rod 4. The activity shaft 10 extends to the inside of the linkage rod 2 near the upper side of the connecting shaft 11, and the activity shaft 10 is movably connected to the linkage rod 2.
[0022] Specifically, operate the crane to drive the lifting lug 9 to move downward, so that the limiting clamping rod 8 contacts the mushroom head type of material. Place the two groups of limiting clamping rods 8 on the outside of the mushroom head type of material. Thus, when the lifting lug 9 moves downward, the limit telescopic part 5 contracts inward, and the bracket 1 and the linkage rod 2 rotate around the activity shaft 10, so that the included angle between the bracket 1 and the linkage rod 2 becomes smaller. At the same time, the linkage rod 2 pushes the moving rod 7 to slide inside the sliding groove 6, so that the two groups of clamping rods 3 move outward respectively. Then operate the crane to move upward, so that the lifting lug 9 drives the bracket 1 to move upward. Thus, the bracket 1 drives the linkage rod 2 to rotate, so that the linkage rod 2 drives the clamping rod 3 to move inward, and the two groups of clamping rods 3 clamp the mushroom head type of material, and the mushroom head type of material can be lifted. By pulling the bracket 1 and making the bracket 1 drive the linkage rod 2 to rotate, so that the linkage rod 2 drives the clamping rod 3 to move, the purpose of facilitating the clamping rod 3 to clamp the mushroom head type of material can be achieved, so as to facilitate the lifting of the mushroom head type of material.
[0023] In this embodiment, the rear end of the bracket 1 is movably connected to a lifting lug 9 through a rotating shaft, and the lower end of the lifting lug 9 is installed at the upper end of the limit telescopic part 5.
[0024] Specifically, by installing the lifting lug 9 on the crane and then operating the crane to drive the lifting lug 9, the purpose of facilitating the movement of the mushroom head type of material can be achieved.
[0025] Working principle:
[0026] In use, first install the lifting lug 9 on the crane, and then operate the crane to drive the lifting lug 9 to move downward, so that the limiting clamping rod 8 contacts the mushroom-head type material. Place the two groups of limiting clamping rods 8 outside the mushroom-head type material. Thus, during the downward movement of the lifting lug 9, the limit telescopic part 5 contracts inward, and the bracket 1 and the linkage rod 2 rotate around the movable shaft 10, so that the angle between the bracket 1 and the linkage rod 2 becomes smaller. At the same time, the linkage rod 2 pushes the moving rod 7 to slide inside the sliding groove 6, so that the two groups of clamping rods 3 move outward respectively. Then, control the crane to move upward, so that the lifting lug 9 drives the bracket 1 to move upward, so that the bracket 1 drives the linkage rod 2 to rotate, so that the linkage rod 2 drives the clamping rod 3 to move inward, and the two groups of clamping rods 3 clamp the mushroom-head type material, and the mushroom-head type material can be lifted. When it is transported to the predetermined position, the mushroom-head type material is placed on the ground, so that the lifting lug 9 moves downward again, and the limit telescopic part 5 contracts inward, so that the two groups of clamping rods 3 move outward, and the mushroom-head type material can be removed. By pulling the bracket 1 and making the bracket 1 drive the linkage rod 2 to rotate, so that the linkage rod 2 drives the clamping rod 3 to move, the purpose of facilitating the clamping rod 3 to clamp the mushroom-head type material can be achieved, so as to facilitate the lifting of the mushroom-head type material. Secondly, by placing the mushroom-head type material on the ground, the limit telescopic part 5 contracts inward, so that the bracket 1 drives the linkage rod 2 to rotate in the reverse direction, so that the clamping rod 3 moves in the reverse direction, and the purpose of facilitating the clamping rod 3 to disengage from the mushroom-head type material can be achieved, so as to facilitate the removal of the mushroom-head type material.
