Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a shock-absorbing and buffering protective device for blasting in mining engineering. Background Technology

[0002] In mining operations, blasting is a key step in obtaining ore resources. However, the shock waves and flying rocks generated during blasting can affect the surrounding environment. To reduce the hazards of blasting, protective devices are commonly used to isolate and protect the work area.

[0003] Current blast protection devices generally have a structure similar to that described in patent application CN202210228395.5, including a baffle, a base, and a lower hinge between the base and the baffle; a connecting part, mounted on the base, for connecting to the ground; and a support part, including a main rod, a secondary rod, and a locking mechanism. One end of the main rod is hinged to the upper part of the baffle, and the main rod and secondary rod are inserted together, with adjustable overlap length. The locking mechanism is used to lock or unlock the relative positions of the main rod and secondary rod. However, this invention is a rigid structure, lacking shock absorption and cushioning, and is prone to deformation and damage when subjected to the strong impact of blasting, making it unsuitable for long-term stable use.

[0004] Therefore, this utility model proposes a shock-absorbing and buffering protection device for blasting in mining engineering to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing and buffering protective device for blasting in mining engineering, which solves the problem of lack of shock absorption and buffering in the existing technology, and the easy deformation and damage.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A shock-absorbing and buffering protective device for blasting in mining engineering includes a protective canopy with a protective door rotatably connected to it. Ventilation holes and observation windows are respectively provided on the side walls of the protective canopy. A closed window is rotatably connected to the ventilation holes inside the protective canopy, and a protective window is fitted to the observation window on the outside of the protective canopy. The protective window is connected to a linkage mechanism located inside the protective canopy. Connecting lugs are fixedly connected to the four corners of the bottom of the protective canopy, and ground nails are connected to the connecting lugs. A protective plate is connected to one side of the protective canopy via a rotating mechanism. The rotating mechanism includes a drive cylinder and a connecting rod. The two ends of the drive cylinder are hinged to the outer side wall of the protective canopy and the protective plate, respectively, and the two ends of the connecting rod are hinged to the protective canopy and the protective plate, respectively. The bottom of the protective plate has a mesh-like perforated structure, and positioning components are symmetrically provided on both sides of its bottom. Protective netting is connected to the positioning components.

[0007] Furthermore, the positioning component includes a positioning plate and a tension spring. The positioning plate is slidably connected to the protective plate, and the tension spring is connected between the positioning plate and the protective plate. The side wall of the positioning plate is provided with a slot for engaging the protective net. Multiple positioning pins are evenly fixedly connected to the positioning plate, and the protective net is provided with pin holes corresponding to the positioning pins. Multiple fixing clamps for fixing the protective net are also fixedly connected to the positioning plate.

[0008] Furthermore, the top of the positioning pin is convex, and the diameter of the convex circle is larger than the diameter of the positioning pin.

[0009] Furthermore, the fixing clamp includes a fixing base, an operating handle, a pressure arm, and a pressure head. The fixing base is fixedly connected to the positioning plate. One end of the operating handle is hinged to the fixing base. The middle part of the operating handle is hinged to one end of the pressure arm. The other end of the pressure arm is connected to the pressure head. The pressure head is set corresponding to the protective net.

[0010] Furthermore, the linkage mechanism includes a first link, a second link, and a drive rod. One end of the first link and the second link are respectively hinged to the protective window, and the other end of the first link and the second link are hinged to the drive rod. The bottom of the drive rod is slidably connected to the track plate, the track plate is fixedly connected inside the protective shed, the track plate is provided with positioning holes, and a positioning rod is longitudinally slidably connected to the drive rod.

[0011] Furthermore, an L-shaped plate is fixedly connected to the side of the protective shed away from the rotating mechanism, and multiple reinforcing ribs are evenly connected to the L-shaped plate. A counterweight is mounted on the upper end of the L-shaped plate.

[0012] Furthermore, the top of the protective shed is fixedly connected with multiple lifting rings.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: This utility model's protective net first absorbs part of the impact energy. The protective net drives the positioning plate and tension spring to move, and the driving cylinder can drive the protective net to rotate at a slight angle, thereby buffering the impact of gravel. The mesh hollow structure at the bottom of the protective plate can disperse the impact force and prevent gravel from directly hitting the protective shed. The use of multi-layer shock absorption and buffering greatly reduces the risk of damage.

[0014] The bottom of the protective shed of this utility model is initially fixed by connecting ears and ground nails. The L-shaped positioning plate, together with the counterweight, and the reinforcing ribs on the L-shaped positioning plate enhance the load-bearing stability, forming a secondary stabilization. The double fixing structure can prevent the device from shifting due to explosive impact. Attached Figure Description

A closed window 5 is rotatably connected to the inside of the protective shed 1 corresponding to the ventilation holes 3. A protective window 6 is installed on the outside of the protective shed 1 corresponding to the observation window 4. The protective window 6 is connected to a linkage mechanism located inside the protective shed 1. The linkage mechanism includes a first link 7, a second link 8, and a drive rod 9. One end of the first link 7 and the second link 8 are respectively hinged to the protective window 6, and the other end of the first link 7 and the second link 8 are hinged to the drive rod 9. The bottom of the drive rod 9 is slidably connected to a track plate 10. The track plate 10 is fixedly connected inside the protective shed 1. A positioning hole 11 is opened on the track plate 10, and a positioning rod 12 is longitudinally slidably connected to the drive rod 9.

[0019] Furthermore, each of the four corners of the bottom of the protective shed 1 is fixedly connected with a connecting lug 13, and a ground nail 14 is connected to the connecting lug 13; an L-shaped plate 15 is fixedly connected to the side of the protective shed 1 away from the rotating mechanism, and multiple reinforcing ribs 16 are evenly connected to the L-shaped plate 15, and a counterweight block 17 is assembled at the upper end of the L-shaped plate 15; multiple lifting rings 18 are fixedly connected to the top of the protective shed 1.

[0020] Furthermore, a protective plate 21 is connected to one side of the protective shed 1 via a rotating mechanism. The rotating mechanism includes a drive cylinder 19 and a connecting rod 20. The two ends of the drive cylinder 19 are hinged to the outer wall of the protective shed 1 and the protective plate 21, respectively. The two ends of the connecting rod 20 are hinged to the protective shed 1 and the protective plate 21, respectively. The bottom of the protective plate 21 has a mesh-like hollow structure, and positioning components are symmetrically arranged on both sides of its bottom. A protective net 31 is connected to the positioning components. The positioning components include a positioning plate 22 and a tension spring 23. The positioning plate 22 is slidably connected to the protective plate 21, and the tension spring 23 is connected between the positioning plate 22 and the protective plate 21. The side wall of the positioning plate 22 has a slot 24 for engaging the protective net 31. Multiple positioning pins 25 are evenly fixedly connected to the positioning plate 22. The protective net 31 has a pin hole 30 corresponding to the positioning pin 25. The top of the positioning pin 25 is convex, and the diameter of the convexity is larger than the diameter of the positioning pin 25.

[0021] Furthermore, the positioning plate 22 is also fixedly connected with a plurality of fixing clamps for fixing the protective net 31. The fixing clamps include a fixing base 26, an operating handle 27, a pressure arm 28, and a pressure head 29. The fixing base 26 is fixedly connected to the positioning plate 22. One end of the operating handle 27 is hinged to the fixing base 26. The middle part of the operating handle 27 is hinged to one end of the pressure arm 28. The other end of the pressure arm 28 is connected to the pressure head 29. The pressure head 29 is set corresponding to the protective net 31.

[0022] The working process of this utility model is as follows: First, drive in ground nails 14 through the connecting ears 13 at the four corners of the bottom of the protective shed 1 to initially fix the position of the protective shed 1. Then, place counterweights 17 on the L-shaped positioning plate 22. The reinforcing ribs 16 on the L-shaped positioning plate 22 enhance the load-bearing stability and further improve the stability of the protective shed 1 against blasting impact, thus preventing the device from shifting.

[0023] Then, the positioning plate 22 of the positioning component secures the protective net 31 into the slot 24, while the positioning hole 11 of the protective net 31 is fitted with a convex positioning pin 25. The convex shape prevents the protective net 31 from falling off. Then, the pressure arm 28 of the clamping clamp is pressed down to close and fix the protective net 31, driving the pressure head 29 to press the protective net 31 tightly, thus completing the double fixation of the protective net 31. Then, the drive cylinder 19 of the rotating mechanism is activated. The cylinder extends and pushes the protective plate 21 to rotate around the connecting rod 20 to the protective state, forming a buffer barrier on the outside of the protective canopy 1.

[0024] When the blast occurs, the protective net 31 first absorbs part of the impact energy. The protective net 31 drives the positioning plate 22 and tension spring 23 to move. The driving cylinder 19 can drive the protective net 31 to rotate at a slight angle, thereby buffering the impact of the debris. The mesh-like hollow structure at the bottom of the protective plate 21 can disperse the impact force and prevent the debris from directly hitting the protective shed 1. The main body of the protective shed 1, together with the ground nail 14 and the counterweight 17, plays a fixing role, resisting the overall impact and preventing the protective shed 1 from shifting and deforming. The sealed window 5 protects the ventilation hole 3, and the protective window 6 protects the observation window 4, preventing debris from entering the shed and damaging the components of the protective shed 1.

[0025] It can also push the drive rod 9 of the linkage mechanism to slide along the track plate 10. The drive rod 9 drives the first link 7 and the second link 8 to rotate, thereby adjusting the opening angle of the protective window 6. After adjustment, the positioning rod 12 is inserted into the corresponding positioning hole 11 of the track plate 10 to lock the position of the drive rod 9 and fix the angle of the protective window 6, so that personnel can observe the blasting situation through the observation window 4. At the same time, the closed window 5 inside the protective shed 1 can be rotated to adjust the opening size of the ventilation hole 3, balance the air pressure inside the shed and ensure ventilation. The device can be hoisted to the next blasting point for reuse through the hoisting ring 18.
