[0002] Lifting equipment involves many corporate process production. First of all, a crane refers to a mechanical crane that lifts in the vertical direction through power for the purpose of horizontal transportation. Its main function is to lift goods. The simplest principle is the pulley block of a movable pulley and a fixed pulley. In junior high school physics, the movable pulley can save effort but consumes distance, so a very long wire rope is wound into the winch drum, and a winch motor, brake, and transmission are installed to form a winch device, and it is equipped with a walking device that can move horizontally and vertically and related safety devices.
[0003] The hook is one of the essential parts of lifting equipment. It can be divided into single hook and double hook according to the shape. The single hook is easy to manufacture and use and is often used to lift light objects, while the double hook is suitable for heavier objects. Generally, the single hook is mainly used in cranes below 30 tons. The single hook anti-trip buckle is a purchased part, which is often damaged during use. There is a great safety risk if the crane continues to be put into use after the anti-trip buckle is damaged.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0021] See also Figure 1-4As shown, a crane hook sealing safety device includes a connecting shell 1, the inner cavity of the connecting shell 1 is provided with a hook body 2, the hook body 2 is located at the bottom of the connecting shell 1, and its function is to lift and transport items, the hook body 2 is bent, the inner cavity of the hook body 2 is provided with a limiting groove 4, the limiting groove 4 is located at the bottom of the inner cavity of the hook body 2, and its function is to provide an adjustment space for a closing rod 6, the inner cavity of the hook body 2 is provided with a threaded sleeve 5, the threaded sleeve 5 is located in the inner cavity of the hook body 2, and its function is to facilitate the staff to insert the closing rod 6 into the inner wall of the limiting groove 4 through the adjusting rod 7 to completely close the opening of the hook body 2, and the inner cavity of the threaded sleeve 5 is provided with an adjusting rod 7.
[0022] One side of the adjusting rod 7 is fixedly connected to a closing rod 6 via a torsion spring. The closing rod 6 is located on one side of the adjusting rod 7 and its function is to close and block the opening of the hook body 2. One end of the closing rod 6 is clamped with the inner wall of the limiting groove 4.
[0023] A thread groove 8 is provided on the surface of the adjusting rod 7. The thread groove 8 is located on the surface of the adjusting rod 7 and cooperates with the threaded sleeve 5 to facilitate the staff to adjust the position of the closing rod 6. The inner cavity of the thread groove 8 is threadedly connected to the inner cavity of the threaded sleeve 5.
[0024] One side of the adjusting rod 7 is fixedly connected with an adjusting block 3 , which is located on one side of the adjusting rod 7 . Its function is to facilitate the staff to turn the adjusting rod 7 to adjust the position of the closing rod 6 . The surface of the adjusting block 3 is provided with anti-slip grooves 10 .
[0025] An anti-sliding block 9 is provided at the bottom of the inner cavity of the hook body 2. The anti-sliding block 9 is located in the inner cavity of the hook body 2. Its function is to prevent the hoisting rigging or the lifting ear from sliding inside the hook body 2. The anti-sliding block 9 is arranged in a tooth shape, and a plurality of anti-sliding blocks 9 are arranged in a ring array.
[0026] A reinforcing rod 11 is fixedly connected to the surface of the closing rod 6. The reinforcing rod 11 is located on one side of the closing rod 6.

[0027] Working principle: First, the staff will press the closing rod 6 downward against the lifting sling or the lifting ear. At this time, the closing rod 6 will be rotated to the inside of the limiting groove 4 through the torsion spring. When the lifting sling or the lifting ear enters the inside of the hook body 2, the anti-sliding block 9 will limit the lifting sling or the lifting ear and increase the surface friction to prevent the lifting sling or the lifting ear from sliding inside the hook body 2. At this time, the closing rod 6 will also be reset by the torsion spring. Then, the staff will twist the adjusting rod 7 through the adjusting block 3 so that the adjusting rod 7 drives the closing rod 6 to continue to be inserted downward. At this time, the closing rod 6 will enter the inside of the limiting groove 4, and the opening of the hook body 2 can be completely closed to achieve a locking effect.
