[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: a shaft safety protection device for a mine hoist, comprising a stone pier 1 and a cross plate 2. The cross plate 2 is arranged between the stone piers 1, which can effectively bear external forces and ensure the stability of the device as a whole. An installation mechanism is arranged inside the cross plate 2 to improve the convenience of the device. A protection mechanism is arranged on the top of the cross plate 2 to further enhance the safety performance; the installation mechanism comprises a central block 3 to provide stable support for the internal structure. The central block 3 is fixedly connected to the inside of the cross plate 2. A sleeve 4 is fixedly connected to the side wall of the cross plate 2. A first spring 5 is arranged inside the sleeve 4. Through the elastic action of the first spring 5, the structure It has reset capability, a slider 6 is slidably connected inside the horizontal plate 2, a connecting rod 7 is fixedly connected to the side wall of the slider 6, and an elliptical block 8 is fixedly connected to the side wall of the connecting rod 7, which helps to improve the stability of the device and the anti-slip performance, a card slot 10 is opened through the inside of the stone pier 1, a transverse groove is opened inside the horizontal plate 2, a handle 9 is fixedly connected to the side wall of the slider 6, and the side wall of the handle 9 is slidably connected in the transverse groove, and rapid adjustment can be achieved by operating the handle 9, the connecting rod 7 is slidably connected inside the horizontal plate 2, the elliptical block 8 is slidably connected inside the card slot 10, one end of the first spring 5 is fixedly connected inside the sleeve 4, and the other end of the first spring 5 is fixedly connected to the side wall of the slider 6;

[0032] When using the equipment for work, first place the stone pier 1 outside the wellhead, ensure that it is placed in a rectangular manner to form a stable foundation. The number of stone piers 1 can be adjusted according to the size of the wellhead to ensure that it can completely cover the area around the wellhead. After the stone pier 1 is placed, the operator pushes the handles 9 on both sides at the same time to make it move relatively, and drive the slider 6 to slide toward the middle along the internal slide rail of the cross plate 2. During this process, the slider 6 will gradually squeeze the first spring 5 inside the cross plate 2, causing the spring to deform. As the slider 6 moves, the elliptical block 8 is also pulled and gradually collected into the internal space of the cross plate 2. Next, place the cross plate 2 between the previously placed stone piers 1 so that it contacts the stone pier 1. When the cross plate 2 is in the correct position, the handle 9 can be released. At this time, the first spring 5 will quickly reset due to the loss of pressure. This reset action will push the elliptical block 8 outward through the slider 6, so that it is stuck in the slot 10 opened in the stone pier 1, and the installation of the cross plate 2 is completed.

[0033] Reference Figure 1-Figure 3The protection mechanism includes an articulated frame 11, which is fixedly connected to the top of the horizontal plate 2 to provide stable support for the overall structure. The articulated frame 11 is internally rotatably connected to a connecting plate 12, and the connecting plate 12 is internally rotatably connected to an articulated frame 2 13. The top of the articulated frame 2 13 is fixedly connected to a crossbeam 14, and the bottom of the crossbeam 14 is fixedly connected to a fixed frame 16. The fixed frame 16 is internally slidably connected to a handle 17. A slot block 15 is fixedly connected to the side wall of the connecting plate 12 on one side. The function of the slot block 15 is to provide guidance and constraint for the movement of the limit column 19. The fixed frame A second spring 18 is arranged inside 16, one end of the second spring 18 is fixedly connected to the inside of the fixed frame 16, and the other end of the second spring 18 is fixedly connected to the side wall of the handle 17, so that the handle 17 can be reset by elastic action, and the bottom of the handle 17 is fixedly connected to the limiting column 19, and the side wall of the limiting column 19 is slidably connected to the inside of the groove block 15, and the articulated frame 11 is arranged on the top of the cross plate 2 in a linear array, which enhances the integrity and bearing capacity of the structure, ensures that it can withstand greater force during use, and provides good stability and protection effect.

[0034] After the installation of the cross plate 2 is completed, the cross beam 14 is moved upward, so that one side of the connecting plate 12 can be deflected inside the hinge frame 11, and the other side can also be synchronously deflected inside the hinge frame 2 13. In this process, the connecting plate 12 gradually transitions from a horizontal state to a vertical state. As the connecting plate 12 gradually tends to a vertical state, the limit column 19 will gradually slide on the inclined surface of the slot block 15. In this process, the limit column 19 cooperates with the slot block 15 to guide the handle 17 to move upward. At the same time, the upward movement of the handle 17 will cause the second spring 18 to gradually move upward. The connecting plate 12 is gradually compressed, and when the connecting plate 12 is finally close to a completely vertical state, the limiting column 19 moves to a position just above the slot block 15. At this time, the second spring 18 loses the continuous squeezing effect of the external force, thereby pushing the handle 17 to move downward, and the limiting column 19 enters the interior of the slot block 15, thereby completing the locking. The insertion of the limiting column 19 not only effectively fixes the connecting plate 12, but also enables the entire structure to stably support the crossbeam 14, ensuring that the connecting plate 12 remains in a vertical state, the crossbeam 14 is reliably supported, and the entire protective mechanism is positioned, thereby achieving the effect of protecting the wellhead.

[0035] Working principle: When using the device for work, first place the stone pier 1 outside the wellhead in a rectangular shape. The number of stone piers 1 to be placed can be changed according to the size of the wellhead. After the stone pier 1 is placed, push the handles 9 on both sides at the same time to make it move relatively, and drive the slider 6 to slide inward inside the cross plate 2 to squeeze the first spring 5 to deform it, and put the elliptical block 8 into the cross plate 2. Then, place the cross plate 2 between the stone piers 1, release the handle 9, and the first spring 5 will lose pressure and reset, and push the slider 6 outward to clamp the elliptical block 8 in the slot 10 opened in the stone pier 1.

[0036] After the installation of the cross plate 2 is completed, by moving the cross beam 14 upward, the other side of the connecting plate 12 is deflected inside the hinge frame 11, and the other side is deflected inside the hinge frame 2 13. When the connecting plate 12 gradually tends to a vertical state, the limit column 19 will gradually slide on the inclined surface of the slot block 15, and push the handle 17 upward to compress the second spring 18, until the limit column 19 moves to the top of the slot block 15. At this time, the second spring 18 loses the extrusion force, pushes the handle 17 to move downward, and inserts the limit column 19 into the slot block 15, thereby completing the support of the connecting plate 12, thereby achieving the effect of protecting the wellhead.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
