[0002] In mining blasting operations, the impact force and flying rocks generated by blasting can pose serious safety threats to surrounding personnel, equipment, and the environment.

[0003] Most existing protective devices have simple structures and limited protective capabilities, failing to effectively buffer and absorb the enormous energy generated by blasting, and thus failing to meet the demand for comprehensive protection in complex blasting environments in mines. For example, some protective devices use only a single rigid structure, which is prone to deformation or even damage when faced with strong blasting impacts, failing to effectively disperse and absorb blasting energy and providing continuous and reliable protection; others use only protective netting for protection, which is easily damaged when faced with strong blasting impacts, resulting in poor protective effects. Therefore, this application proposes a protective device for blasting mining. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This embodiment provides a protective device for blasting mining, the structural diagram of which is shown below. Figures 1-5 As shown, it includes a first arm 1, a second arm 2, a first support arm 3, a second support arm 4, and a back plate 5.

[0024] In this embodiment, the first arm 1 is arranged horizontally, and the first support arm 3 is located at both ends of the first arm 1 and is distributed perpendicularly to the first arm 1. Multiple fixed rods 9 are vertically fixed at the bottom of the first support arm 3. The entire protective device is fixedly installed by inserting the fixed rods 9 into the ground.

[0025] Furthermore, the second arm 2 is movably positioned above the first arm 1 and maintains the same length direction. Second support arms 4 are provided at both ends of the second arm 2, perpendicular to the second arm 2. A back plate 5 is hinged to the top of the second arm 2, and the back plate 5 is inclined towards the side facing the second support arm 4. A support rod 8 is inclinedly hinged between the end of the second support arm 4 away from the second arm 2 and the top of the back plate 5. The support rod 8 has an elastic telescopic function, specifically: the support rod 8 includes a sleeve arm 16 hinged to the top of the second support arm 4 at the end away from the second arm 2, and a connecting arm 17 movably passing through the top of the sleeve arm 16. The connecting arm 17 is hinged to the middle position of the side of the back plate 5 facing the second support arm 4. A second spring 18 is provided between the end of the connecting arm 17 extending into the sleeve arm 16 and the inner bottom wall of the sleeve arm 16. When the back plate 5 is subjected to external force, the support rod 8 can buffer part of the impact force through the elastic telescopic movement of the second spring 18.

[0026] In a further embodiment, a groove 12 is formed on the upper surface of the first arm 3, the groove 12 is arranged along the length of the first arm 3, and a slider 13 is slidably embedded in the groove 12. The second arm 4 is fixedly connected to the slider 13, and a first spring 14 is provided between the end of the slider 13 away from the first arm 1 and the inner end wall of the groove 12. A guide rod 15 is fixed inside the groove 12, and the slider 13 is slidably sleeved with the guide rod 15. The first spring 14 is sleeved on the guide rod 15. When the second arm 2 and the second arm 4 are subjected to external force and move towards the first arm 3, the slider 13 slides in the groove 12, and the first spring 14 is compressed, thereby achieving buffering and force relief for the movement of the second arm 2 and the second arm 4.

[0027] In a further embodiment, a buffer panel 6 is provided on the side of the back plate 5 away from the second support arm 4. An airbag 7 is sandwiched between the buffer panel 6 and the back plate 5. The buffer panel 6 is composed of a frame 10 and a rubber woven mesh 11 disposed in the frame 10. The rubber woven mesh 11 is woven from rubber strips. When flying stones or other objects generated by the explosion impact the buffer panel 6, the rubber woven mesh 11 and the airbag 7 can play a role in buffering and absorbing energy, further enhancing the protective effect.

[0028] Working principle:

[0029] When blasting operations in a mine generate impact forces and flying rocks, the flying rocks first impact the buffer panel 6. The rubber woven mesh 11 in the buffer panel 6, through its own elastic deformation and interaction with the airbag 7, initially buffers and absorbs the impact energy of the flying rocks. Simultaneously, the impact force is transmitted to the back plate 5, causing it to tend to move towards the second support arm 4. At this time, the second spring 18 in the support rod 8 is compressed, using elastic extension and contraction to buffer part of the impact force. Furthermore, the impact force also causes the second arm 2 and the second support arm 4 to tend to move towards the first support arm 3. The second support arm 4 drives the slider 13 to slide within the groove 12, compressing the first spring 14 and further buffering and dissipating the impact force. Through the synergistic effect of these multi-stage buffer structures, the enormous energy generated by the blasting is effectively dispersed and absorbed, thereby achieving reliable protection for the surrounding environment and personnel.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
