Description

Technical Field

[0001] This utility model relates to the field of blast protection nets, and in particular to a blast protection net that can be deployed quickly. Background Technology

[0002] Blasting protection nets are crucial safety facilities used in blasting operations. They are primarily made of high-strength steel wire, nylon, or polyester fiber, and have a mesh structure. In mining, tunneling, and urban demolition blasting operations, they effectively intercept flying rocks and debris, controlling them within a safe range and preventing harm to the surrounding environment, personnel, and equipment. Types include active and passive protection nets; the former actively intercepts flying rocks, while the latter receives and cushions impacts.

[0003] However, the current blasting protection nets have the following defects: First, they are inconvenient to store and organize, which affects the efficiency of rapid deployment, is time-consuming and labor-intensive, and cannot meet the rapid response requirements of blasting operations; Second, they have poor adaptability to complex terrain, are difficult to keep perpendicular to the ground, and lack stability in special terrains such as undulating and soft terrain, which greatly reduces the protective effect.

[0004] In response to this technical problem, this application proposes a rapidly deployable blast protection net. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapidly deployable blasting protection net. This net is designed to be easy to store and organize, enabling rapid deployment and ensuring it remains perpendicular to the ground, thus improving its adaptability to various complex terrains.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rapidly deployable blast protection net includes a protective net, two support rods, and a storage box. The protective net has frame edges fixedly connected to both its left and right sides. Two insert blocks are rotatably connected to one side of each frame edge. These insert blocks are inserted into the interior of the support rods. Insert rods are inserted into the interior of the support rods, passing through the insert blocks. A positioning strip is fixedly connected to the bottom interior of the storage box. A winding assembly is installed inside the storage box to wind up the protective net. A support assembly is located at the rear of each support rod to support it.

[0008] Furthermore, the storage assembly includes two turntables rotatably connected inside the storage box, a winding roller and a clamping plate are fixedly connected between the two turntables, and two limiting rods are inserted into the inside of the clamping plate.

[0009] Furthermore, a handle is fixedly connected to the front side of the turntable, and a positioning rod is inserted into the inside of the handle, with the bottom end of the positioning rod inserted into the inside of the storage box.

[0010] Furthermore, the support assembly includes a groove formed on the rear side of the support rod, a threaded rod is rotatably connected inside the groove, a slide block is threadedly connected to the outer wall of the threaded rod, and the slide block is slidably connected inside the groove.

[0011] Furthermore, a support leg is rotatably connected to the rear side of the support rod, and the support leg and the slide are connected by a connecting rod. One end of the connecting rod is rotatably connected to the inside of the support leg, and the other end of the connecting rod is rotatably connected to the inside of the slide.

[0012] Furthermore, a knob is rotatably connected to the top of the support rod via a damping shaft, the top of the threaded rod is fixedly connected to the inside of the knob, a protective frame is fixedly connected to the top of the support rod, and the knob is located inside the protective frame.

[0013] Furthermore, a threaded cap is fixedly connected to the top end of the insertion rod, and a ring is fixedly connected to the top end of the support rod, with the threaded cap threadedly connected to the outer wall of the ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by inserting the limiting rod into the clamp plate, the limiting rod is inserted into the insert block, thereby fixing one side of the protective net to the take-up roller. Then, by rotating the front turntable through the handle, the front turntable drives the take-up roller to rotate, and the rear turntable rotates, thereby winding up the protective net. This makes the protective net easy to store and convenient for workers to organize, thus enabling the protective net to be deployed quickly.

[0016] 2. In this utility model, the sliding block is driven to slide up and down by the threaded rod, which in turn drives the connecting rod to move, thereby causing the connecting rod to rotate the outrigger, thus adjusting the angle of the outrigger so that the outrigger can rotate to the ground, allowing the support rod to fit against the ground and maintain a perpendicular state to the ground. This ensures that the protective net remains perpendicular to the ground, improving its adaptability in various complex terrains. Attached Figure Description

[0026] 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.

[0027] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a rapidly deployable blast protection net, comprising a protective net 1, two support rods 2, and a storage box 5. The protective net 1 has frame 10 fixedly connected to both its left and right sides. The protective net 1 is made of woven metal wire mesh, and the frame 10 is made of lightweight aluminum alloy. Two insert blocks 12 are rotatably connected to one side of the frame 10. The insert blocks 12 are inserted into the interior of the support rods 2, and insert rods 11 are inserted into the interior of the support rods 2, passing through the insert blocks 12. By inserting the insert blocks 12 into the interior of the support rods 2 and inserting the insert rods 11 into the support rods 2, the insert blocks 12 are fixed in the support rods 2, thereby fixing the protective net 1 between the two support rods 2. A positioning strip 9 is fixedly connected to the bottom inside the storage box 5 to position the support rods 2 and store them. Figures 5-7 The storage box 5 has two turntables 8 rotatably connected inside. A winding roller 18 and a clamping plate 7 are fixedly connected between the two turntables 8. Two limiting rods 21 are inserted into the clamping plate 7. By inserting the insert block 12 on the frame 10 between the clamping plate 7 and the winding roller 18, and inserting the limiting rod 21 into the clamping plate 7, the limiting rod 21 is inserted into the insert block 12, thereby fixing one side of the protective net 1 to the winding roller 18, which facilitates the subsequent winding of the protective net 1. A handle 6 is fixedly connected to the front side of the front turntable 8. A positioning rod 20 is inserted into the handle 6. The bottom end of the positioning rod 20 is inserted into the storage box 5. By rotating the front turntable 8 through the handle 6, the front turntable 8 drives the winding roller 18 to rotate, and the rear turntable 8 rotates, thereby winding the protective net 1. By inserting the positioning rod 20 into the handle 6 and inserting it into the storage box 5, the front turntable 8 is fixed, preventing the winding roller 18 from rotating and causing the protective net 1 to unfold.

[0028] Reference Figure 1 and Figure 4A groove is provided on the rear side of the support rod 2. A threaded rod 14 is rotatably connected inside the groove. A slide block 15 is threadedly connected to the outer wall of the threaded rod 14. The slide block 15 is slidably connected inside the groove. A support leg 4 is rotatably connected to the rear side of the support rod 2. The support leg 4 and the slide block 15 are connected by a connecting rod 3. One end of the connecting rod 3 is rotatably connected to the inside of the support leg 4, and the other end of the connecting rod 3 is rotatably connected to the inside of the slide block 15. A knob 17 is rotatably connected to the top of the support rod 2 through a damping shaft. The top of the threaded rod 14 is fixedly connected to the inside of the knob 17. A protective frame 16 is fixedly connected to the top of the support rod 2. The knob 17 is located in the protective frame 16. Internally, rotating the knob 17 causes the threaded rod 14 to rotate, which in turn drives the slide 15 to slide up and down. The slide 15 then drives the connecting rod 3, which in turn drives the outrigger 4 to rotate, adjusting its angle so that it can rotate onto the ground. This allows the support rod 2 to be in contact with the ground, maintaining a perpendicular position. This ensures the protective net 1 remains perpendicular to the ground, improving its adaptability to various complex terrains. The knob 17 is protected by the protective frame 16 to prevent rotation due to impacts or other factors. Figure 2 and Figure 3 The top end of the insertion rod 11 is fixedly connected to a threaded cap 13, and the top end of the support rod 2 is fixedly connected to a ring 19. The threaded cap 13 is threadedly connected to the outer wall of the ring 19. By inserting the insertion rod 11 into the ring 19, the insertion rod 11 is inserted into the support rod 2. The threaded cap 13 is rotated to make it threadedly connected to the ring 19, thereby fixing the insertion rod 11 to the support rod 2.

[0029] Working principle: First, remove the support rod 2 from the positioning strip 9. Then, pull the positioning rod 20 off the handle 6 to release it from the front turntable 8. Next, grasp the frame 10 of the protective net 1 that is not fixed by the clamp 7, and then pull the protective net 1 through this frame 10 to unfold it from the take-up roller 18. When the protective net 1 is fully unfolded, the frame 10 fixed by the clamp 7 will be exposed. Then, pull the limiting rod 21 off the clamp 7 to release the insert block 12 from the clamp 7. Then, the protective net 1 can be removed from the storage box 5. Then, insert the insert block 12 into the support rod 2, and then insert the insert rod 11 into the ring 19 from top to bottom to make the insert rod 1... Insert the insert 11 into the support rod 2, allowing it to pass through the insert block 12 and fix the insert block 12 onto the support rod 2. Then, rotate the threaded cap 13 to connect it with the ring 19, thus fixing the insert 11 onto the support rod 2. This completes the work of fixing the protective net 1 between the two support rods 2. Next, rotate the rotating knob 17 to rotate the threaded rod 14, causing the threaded rod 14 to drive the slide block 15 to slide up and down. This, in turn, drives the connecting rod 3 to move, which in turn drives the support leg 4 to rotate, thereby adjusting the angle of the support leg 4 so that it can rotate to the ground. This allows the support rod 2 to be in contact with the ground, making the support rod... 2. Keep the netting perpendicular to the ground, thus ensuring the netting is perpendicular to the ground and completing its deployment. When the netting needs to be stored, first rotate the threaded cap 13 to disengage it from the ring 19, then pull the insert rod 11 out of the support rod 2, and then pull the insert block 12 out of the support rod 2. Next, insert the insert block 12 on the frame 10 between the clamping plate 7 and the winding roller 18, and insert the limiting rod 21 into the clamping plate 7 so that the limiting rod 21 is inserted into the insert block 12, thereby fixing one side of the netting to the winding roller 18. Then, rotate the front turntable 8 using the handle 6, causing the front turntable 8 to drive the winding roller 18 to rotate, and causing the rear turntable 8 to rotate. The protective net 1 is rolled up by rotating the handle 6. The front turntable 8 is fixed by inserting the positioning rod 20 into the handle 6 and then into the storage box 5 to prevent the protective net 1 from unfolding due to the rotation of the winding roller 18. Then, the knob 17 is turned to rotate the threaded rod 14, which drives the slide 15 to slide up and down. The slide 15 drives the connecting rod 3 to move, which in turn drives the support leg 4 to rotate. The support leg 4 is rotated to the rear of the support rod 2, so that the support leg 4 is folded and stored. Then, the insertion rod 11 is fixed to the support rod 2 in the same way as described above. Finally, the support rod 2 is placed on the positioning strip 9 to complete the storage of the protective net 1.
