[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] The utility model proposes a feeding device, comprising: a lifting hook main body 1;
[0029] The top of the lifting hook body 1 is provided with a lifting ring 2 through an integral molding, and the lifting hook body 1 is used to rotatably support the inner ring body 3. Before using this device to load the building materials, the lifting ring 2 is fixed to the bottom of the lifting rope of the crane; an inner ring body 3 is rotatably installed on the inner side of the lifting hook body 1, and the inner ring body 3 is used to support the hanging ring limit buckle 4, and the inner ring body 3 rotates inside the lifting hook body 1 so that the position of the hanging ring limit buckle 4 can be adjusted, thereby realizing the locking or loosening of the hanging ring on the top of the container filled with building materials; the inner ring body 3 is installed on the inner side of the lifting hook body 1 There is a hanging ring limit buckle 4 fixed. When loading, you can hold the adjusting rod 5 to push the inner ring body 3 to rotate inside the lifting hook body 1, so that the hanging ring limit buckle 4 can be aligned with the opening on the left side of the top of the lifting hook body 1. Then you can put the hanging ring on the top of the container through the opening on the left side of the top of the lifting hook body 1 into the open groove inside the hanging ring limit buckle 4. At this time, pull the hanging ring on the top of the container downward, and then the hanging ring will pull the inner ring body 3 to rotate inside the lifting hook body 1 through the hanging ring limit buckle 4. At this time, the hanging ring limit buckle 4 can be pulled upward due to the vertical pulling force of the hanging ring When the hook 1 is lifted, the notch on the outside of the inner ring 3 is rotated to the top, and the magnet on the top of the positioning slider 6 is aligned with the magnet block 7. They repel each other, so the magnet block 7 will push the positioning slider 6 to move down quickly and embed into the notch groove on the outside of the inner ring body 3, thereby limiting the rotation of the inner ring body 3 on the inside of the lifting hook body 1; a magnet block 7 is also fixed on the inside of the top of the lifting hook body 1. During lifting, the notch groove on the outside of the inner ring body 3 will rotate to the top. Because the magnet on the top of the positioning slider 6 and the magnet block 7 repel each other, the magnet block 7 will push the positioning slider 6 to move down quickly and embed into the notch groove on the outside of the inner ring body 3, thereby limiting the rotation of the inner ring body 3 on the inside of the lifting hook body 1.
[0030] In the embodiment of the present disclosure, Figures 1-4 As shown, the adjustment rod 5 is a cylindrical rod, and the positions of the adjustment rod 5 and the hanging ring limit buckle 4 are symmetrical with respect to the center of the inner ring body 3. When in use, the adjustment rod 5 can be held to push the inner ring body 3 to rotate inside the lifting hook body 1, so that the hanging ring limit buckle 4 can be aligned with the opening on the left side of the top of the lifting hook body 1.
[0031] In the embodiment of the present disclosure, Figure 1-Figure 5As shown, an annular groove is provided on the inner side of the lifting hook body 1, and the edge outer wall and the front and rear side outer walls of the inner ring body 3 are tightly attached to the inner wall of the annular groove inside the lifting hook body 1. Therefore, the inner ring body 3 can rotate stably inside the lifting hook body 1 without shaking, thereby ensuring the stability when lifting the building materials.
[0032] In the embodiment of the present disclosure, Figure 3 and Figure 6 As shown, a notch is provided on the outer side of the inner ring body 3. When the hanging ring limit buckle 4 rotates to the bottom, the notch on the outer side of the inner ring body 3 will be at the top, and when the positioning slider 6 slides down, its bottom can be embedded in the notch on the outer side of the inner ring body 3. During lifting, the notch on the outer side of the inner ring body 3 will rotate to the top. Because the magnet on the top of the positioning slider 6 and the magnet block 7 repel each other, the magnet block 7 will push the positioning slider 6 to move down quickly and embed into the notch on the outer side of the inner ring body 3, thereby limiting the rotation of the inner ring body 3 inside the lifting hook body 1.
[0033] In the embodiment of the present disclosure, Figures 1-4 When the lifting hook 1 is lifted, the lifting link 1 is lifted and the lifting link 1 is in a state of being lifted and lowered, so that the lifting link 1 can be lifted and lowered.
[0034] In the embodiment of the present disclosure, Figure 1-Figure 5 As shown, an opening is provided at the top left position of the lifting hook body 1, and the width of the opening at the top left position of the lifting hook body 1 is equal to the width of the opening groove inside the hanging ring limit buckle 4. When loading, the adjusting rod 5 can be held to push the inner ring body 3 to rotate inside the lifting hook body 1, so that the hanging ring limit buckle 4 can be aligned with the opening at the top left position of the lifting hook body 1, and then the hanging ring at the top of the container can be passed through the opening at the top left position of the lifting hook body 1 and placed into the opening groove inside the hanging ring limit buckle 4.
[0035] Example 2, based on Example 1, Figures 1-6As shown, a magnet is also provided on the top of the positioning slider 6, and the adjacent poles of the magnet on the top of the positioning slider 6 and the magnet block 7 are the same poles. When lifting, the notch groove on the outside of the inner ring body 3 will rotate to the top. Because the magnet on the top of the positioning slider 6 and the magnet block 7 repel each other, the magnet block 7 will push the positioning slider 6 to move down quickly and embed into the notch groove on the outside of the inner ring body 3, thereby limiting the rotation of the inner ring body 3 inside the lifting hook body 1.
[0036] The working principle of this embodiment is as follows: before using this device to load building materials, first fix the lifting ring 2 to the bottom of the lifting rope of the crane. When it is necessary to lift the building materials for loading, first put the building materials in the loading container, and then hold the adjusting rod 5 to push the inner ring body 3 to rotate inside the lifting hook body 1, so that the hanging ring limit buckle 4 can be aligned with the opening on the left side of the top of the lifting hook body 1, and then the hanging ring on the top of the container can be passed through the opening on the left side of the top of the lifting hook body 1 and placed into the open groove inside the hanging ring limit buckle 4. At this time, pull the hanging ring on the top of the container downward with force, and then the hanging ring will pull the inner ring body 3 to rotate inside the lifting hook body 1 through the hanging ring limit buckle 4, and now the hanging ring limit buckle 4 can Because the vertical pulling force of the hanging ring rotates to the bottom, the notch groove on the outside of the inner ring body 3 will also rotate to the top. Because the magnet on the top of the positioning slider 6 and the magnet block 7 repel each other, the magnet block 7 will push the positioning slider 6 to move down quickly and embed into the notch groove on the outside of the inner ring body 3, thereby limiting the rotation of the inner ring body 3 inside the lifting hook body 1. Because the hanging ring on the top of the container is located inside the hanging ring limit buckle 4 and cannot move, it can prevent the hanging ring from falling off. When the loading is completed and the hanging ring needs to be removed, you only need to push the positioning slider 6 up to disengage the notch groove on the outside of the inner ring body 3, and then push the inner ring body 3 to rotate, so that the hanging ring can be taken out through the opening on the left side of the top of the lifting hook body 1.
