[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a quick connection device for a dispatching winch hook head, comprising a hook head body 1, grooves 101 are provided at the upper and lower ends of the hook head body 1, a hollow groove 102 is provided inside the hook head body 1, a mounting rod 11 is fixedly installed inside the two grooves 101, an upper splint 2 and a lower splint 3 are movably installed on one side of the hook head body 1, the upper splint 2 and the lower splint 3 have the same structure and are in opposite directions, the front and rear ends of the upper splint 2 are fixedly connected with a connecting block 1 21, the front and rear ends of the lower splint 3 are fixedly connected with a connecting block 2 31, a connecting block 4 is movably installed on the other side of the hook head body 1, a through hole 401 is provided on the top of the connecting block 4, a movable block 22 is fixedly connected to one side of the outer wall of the upper splint 2, the movable block 22 is movably installed on the surface of the mounting rod 11, a bolt 5 is provided inside the connecting block 1 21, one end of the surface of the bolt 5 passes through the interior of the connecting block 2 31, and a fastener is installed at the bottom of the bolt 5.

[0024] In this embodiment, the movable block 22 on the side of the upper clamp 2 is movably installed on the surface of the mounting rod 11, so that the upper clamp 2 can rotate around the mounting rod 11 as the center of the circle, thereby adjusting the angle of the upper clamp 2. The same is true for the lower clamp 3. The mine car is hooked by the upper clamp 2 and the lower clamp 3, and then the upper clamp 2 and the lower clamp 3 are moved at the same time to make the upper clamp 2 and the lower clamp 3 bite, and then the bolt 5 is inserted into the connecting block 1 21 and the connecting block 2 31, and the fastener is installed and rotated at the bottom of the bolt 5 to connect and fix the upper clamp 2 and the lower clamp 3 to prevent the hook head body 1 from falling off the mine car. Example

[0025] like Figure 1-Figure 5 As shown, one end of the connecting block 4 is slidably installed inside the hollow groove 102, and a mounting groove 402 is opened on one side of the inner wall of the through hole 401. Two guide rods 12 are fixedly installed inside the hollow groove 102, and springs 13 are provided on the surfaces of the two guide rods 12. Slide blocks 41 are fixedly connected on both sides of the connecting block 4. The slide blocks 41 are slidably installed on the surfaces of the guide rods 12, and one side of the slide block 41 is tightly fitted with one end of the spring 13. A fixing rod 14 is fixedly installed inside the hollow groove 102, and the surface of the fixing rod 14 movably passes through the interior of the connecting block 4. A stabilizing plate 15 is fixedly connected to one side of the fixing rod 14, and the stabilizing plate 15 is located inside the hollow groove 102.

[0026] In this embodiment, the steel rope is connected to the connecting block 4 by passing one end of the steel rope through the through hole 401 and fixing the steel rope with a rope clamp. When the hook head body 1 is used to hook the mine car, the connecting block 4 moves outward under the tension, and at the same time, the slider 41 on the side of the connecting block 4 slides on the surface of the guide rod 12 and squeezes the spring 13 on the surface of the guide rod 12. Since one end of the fixing rod 14 is fixedly installed on the inner wall of the hollow groove 102, when the connecting block 4 moves outward, the stabilizing plate 15 moves relatively inside the installation groove 402, and the stabilizing plate 15 approaches the surface of the steel rope, squeezes and limits the steel rope inside the through hole 401, thereby improving the stability between the steel rope and the connecting block 4.

[0027] The working principle of this embodiment is as follows: by hooking the mine car with the upper clamping plate 2 and the lower clamping plate 3, and then simultaneously moving the upper clamping plate 2 and the lower clamping plate 3 to make the upper clamping plate 2 and the lower clamping plate 3 bite, and then passing the bolt 5 into the connecting block 1 21 and the connecting block 2 31, installing and rotating the fastener at the bottom of the bolt 5 to connect and fix the upper clamping plate 2 and the lower clamping plate 3, passing one end of the steel rope into the through hole 401, and fixing the steel rope with a rope clamp to connect the steel rope to the connecting block 4. When the hook head body 1 is used to hook the mine car, the connecting block 4 is subjected to the pulling force and moves outward. At the same time, the slider 41 slides on the surface of the guide rod 12 and squeezes the spring 13. The stabilizing plate 15 moves relatively inside the mounting groove 402 to squeeze and limit the steel rope inside the through hole 401, thereby improving the stability between the steel rope and the connecting block 4, and at the same time achieving the effect of facilitating the connection between the hook head body 1 and the steel rope.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
