DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the 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.

[0029] See also Figure 1-Figure 8 As shown, a protective safety shed for mine blasting comprises two groups of symmetrically arranged first mounting frames 1 and second mounting frames 6, both sides of the upper surface of the first mounting frames 1 are welded and fixed with limit ears 2, and the outer surfaces of the adjacent sides of the two groups of first mounting frames 1 are welded and installed with protective plates 4, the two groups of protective plates 4 are movably connected by hinge shafts, and both sides of the upper surfaces of the protective plates 4 are integrally fixed with a plurality of convex limit rings 5, and the side away from the lower surfaces of the two groups of protective plates 4 is foldably installed with side guard plates 24 through hinges, and the outer surfaces of the distant sides of the side guard plates 24 are provided with connecting ears 26, and the upper surfaces of the connecting ears 26 are penetrated and installed with latches 27, and the adjacent sides of the lower surfaces of the two groups of protective plates 4 are fixed with convex side stoppers 25, and one side of the outer surface of the side stopper 25 is snap-fitted with the other side of the outer surface of the side guard plate 24;

[0030] The second mounting frame 6 is welded and fixed with docking ears 7 on both sides of the lower surface. The second mounting frame 6 is installed and connected with the first mounting frame 1 by staggered docking between the docking ears 7 and the limiting ears 2. One side of the outer surface of the limiting ear 2 is spirally penetrated and installed with a locking bolt 3. The output end of the locking bolt 3 spirally penetrates the docking ear 7 and extends outward. A fixed seat 8 is integrally fixed in the middle of the lower surface of the second mounting frame 6. A movable shaft rod 9 is commonly fixed on the side close to the fixed seats 8. Several buffer plates 10 are commonly laid and installed on the side close to the second mounting frames 6. A movable sleeve 11 is integrally fixed in the middle of the lower surface of the several buffer plates 10. The movable sleeve 11 is sleeved and installed on the outer surface of the movable shaft rod 9. Compression springs 12 are provided on both sides of the lower surface of the buffer plate 10. The other end of the compression spring 12 is embedded and installed in the limiting ring 5. A connecting belt 13 is commonly fixed on the side close to the several symmetrically arranged buffer plates 10.

[0031] The limiting ear 2 of the first mounting frame 1 is butted with the butt ear 7 of the second mounting frame 6, and is locked and fixed with the locking bolt 3, so that the protective structure and the buffer structure can be connected to complete the installation of the overall safety shed, and the flying stone blocking protection is performed by the protective plate 4. The two sets of protective plates 4 are movably connected by a hinge shaft, and the protective plates 4 can be folded, so as to facilitate transportation and use in the mine;

[0032] The impact force generated by flying stones can be buffered by the buffer plate 10. When flying stones fall on any position on the buffer plate 10, the position of the buffer plate 10 hit by flying stones can sink to relieve the force under the active cooperation of the movable shaft rod 9 and the movable sleeve 11, and the compression spring 12 can be squeezed to further relieve the impact force. When the flying stones are removed, the compression spring 12 can elastically rebound, and the sunken part of the push-pushing buffer plate 10 is reset. The compression spring 12 can be limited during its operation by the limiting ring 5 to avoid derailment. The buffer plates 10 can be connected in series by the connecting belt 13, so as to be folded and transported to the mine for installation and use.

[0033] The safety shed is set up by adjusting the two sides of the safety shed to the direction that is easy to contact with flying rocks, and the side guards 24 set on the lower surfaces of the two groups of protective plates 4 are unfolded, and then the side guards 24 are used to block and protect the direction in which the safety shed is easy to contact with flying rocks. After the side guards 24 are unfolded, the pins 27 can be inserted in the direction of the mine ground to complete the unfolding and fixing of the side guards 24. When the side block 25 is a rubber structure, it has a certain compression performance, so that when the side guard 24 is in a folded state, its end in contact with the side block 25 will squeeze the side block 25, and at the same time, the side block 25 uses its own compression performance to rebound, thereby squeezing and limiting the side guard 24, and completing the folding, storage and fixing of the side guard 24;

[0034] A support screw 14 is movably mounted on the lower surface of the first mounting frame 1 on one side away from the other through an axle seat, an adjusting screw barrel 15 is spirally sleeved on the other end of the support screw 14, the height of the adjusting screw barrel 15 is greater than the height of the support screw 14, a docking barrel 16 is integrally fixed on the upper surface of the adjusting screw barrel 15, the inner surface of the docking barrel 16 is not provided with a thread, a universal wheel 17 is movably mounted on the lower surface of the adjusting screw barrel 15 through a bearing, fixing ears 18 are integrally fixed on the upper parts of both sides of the outer surface of the universal wheel 17, a fixing hole is opened on the upper surface of the other side of the fixing ear 18, and the front end of the outer surface of the adjusting screw barrel 15 is clamped A telescopic isolation belt mechanism 19 is installed, and a clamp ring 20 is fixedly provided at the upper and lower parts of the rear end of the outer surface of the telescopic isolation belt mechanism 19. The clamp ring 20 is clamped and installed on the outer surface of the adjusting screw barrel 15. The telescopic isolation belt mechanism 19 includes a storage barrel, which is arranged in a hollow columnar shape. A movable shaft 21 is commonly provided between the inner bottom surface and the inner top surface of the storage barrel. An isolation belt 22 is movably sleeved and installed on the outer surface of the movable shaft 21. One end of the isolation belt 22 passes through one side of the inner surface of the storage barrel and extends to the outside. A clamping shaft is fixedly provided at the end of the isolation belt 22 extending to the outside, and a clamping hoop 23 is fixedly provided at the upper and lower parts of the outer surface of the other side of the storage barrel.

[0035] The support height of the safety shed can be adjusted by the support screw 14 in cooperation with the adjusting screw barrel 15. By utilizing the fact that the inner surface of the docking barrel 16 is not provided with threads, the support screw 14 can be conveniently inserted into the interior thereof for docking and installation with the adjusting screw barrel 15. The overall movement of the safety shed can be controlled by the universal wheel 17. When it is moved to a suitable position, it can be fixed in the mine soil by means of a fixing tool through the fixing ear 18. The isolation belt 22 in the telescopic isolation belt mechanism 19 is pulled out from the storage barrel, and the clamping shaft provided at the withdrawal end of the isolation belt 22 is clamped into the clamp 23 provided on the component storage barrel of the remaining telescopic isolation belt mechanisms 19, thereby completing the full deployment of the isolation belt 22. At this time, the deployed isolation belt 22 can shield and protect the four sides of the safety shed, and cooperate with the side guard plate 24 to further block the gravel falling to the side wing of the safety shed.

[0036] When the present invention is in use, firstly, the various structures of the safety shed can be disassembled and transported to a suitable position in the mine, and then the various structures are unfolded and assembled, the limiting ear 2 of the first mounting frame 1 and the docking ear 7 of the second mounting frame 6 are staggered and docked, and the locking bolts 3 are used in series to lock and fix, and the assembly connection of the first mounting frame 1 and the second mounting frame 6 can be completed. At this time, the buffer plate 10 can cover the top of the protective plate 4, and the support screw 14 can be inserted into the docking tube 16. After the insertion is completed, the adjusting screw tube 15 can be turned clockwise according to the required support height of the safety shed to shrink the support screw 14. When the safety shed is adjusted to a suitable height, The safety shed is driven to move to the protection area by the universal wheel 17, and the two sides of the safety shed are adjusted to the direction that is easy to contact with flying rocks. At this time, the side guard plates 24 arranged on the lower surfaces of the two sets of protection plates 4 can be unfolded, and then the side guard plates 24 are used to block and protect the direction in which the safety shed is easy to contact with flying rocks. After the side guard plates 24 are unfolded, the latch 27 can be inserted in the direction of the mine ground to complete the unfolding and fixing of the side guard plates 24, and the universal wheel 17 is locked and inserted into the mine soil with the help of a fixing tool through the fixing ear 18 to fix the safety shed, and at the same time, the telescopic isolation belt mechanism 19 is further unfolded to block the periphery of the safety shed;

[0037] After the safety shed is prepared, flying rocks can be blocked. When flying rocks fall onto the buffer plate 10, under the coordinated active support of the movable shaft rod 9 and the movable sleeve 11, the position of the buffer plate 10 hit by the flying rocks can sink to unload the force, thereby reducing the deformation risk of the buffer plate 10 and squeezing the compression spring 12 to further alleviate the impact force of the flying rocks. When the flying rocks are removed, the compression spring 12 can elastically rebound, pushing the sunken part of the buffer plate 10 to reset, thereby completing the protection.
