Technical Field

[0001] This utility model relates to the technical field of explosion protection, and in particular to a splash-proof buffer structure for blasting. Background Technology

[0002] Mining blasting is a key technology that uses the energy generated by explosives to break rocks and strip ore bodies or overburden layers in order to carry out subsequent mining, excavation and transportation operations.

[0003] However, during mine blasting, even outside the safe distance, small fragments of rock inevitably scatter in all directions. These random fragments not only endanger personnel safety but also damage equipment at the blasting site. Therefore, in order to separate and buffer these small fragments of rock that scatter in all directions and protect personnel and equipment at the site, the anti-splash buffer structure for blasting proposed in this application is proposed. Utility Model Content

Detailed Implementation

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0028] like Figures 1 to 4 As shown, a splash buffer structure 10 for blasting includes a base 100, a top plate 200, a shielding member 300, and two side plates 400. One end of each side plate 400 is rotatably connected to both ends of the base 100. An adjusting post 500 is provided at the end of each side plate 400 away from the base 100. The shielding member 300 is engaged with the base 100 and the top plate 200 respectively. The two adjusting posts 500 are used to support both ends of the top plate 200 respectively. When the adjusting posts 500 are rotated under force, they are used to move the top plate 200 away from the base 100, thereby causing the top plate 200 and the base 100 to jointly tension the shielding member 300.

[0029] It should be noted that the two side plates 400 are rotated relative to the base 100 so that the angle between the side plates 400 and the base 100 is a right angle. The two ends of the top plate 200 are held by the adjusting columns 500 on the two side plates 400 respectively. Then, the blocking member 300 is hooked to the base 100 and the top plate 200 respectively. In this way, when the adjusting column 500 is rotated under force, the adjusting column 500 will rotate relative to the side plates 400, thereby causing the adjusting column 500 to push the top plate 200 away from the base 100, so that the blocking member 300 hooked between the base 100 and the top plate 200 is tensioned. Thus, the blasting splash buffer structure 10 of this application is formed. The blasting splash buffer structure 10 of this application has the following advantages: First, the main structure of this application (including the base 100, the top plate 200, and the two side plates 400) is a detachable and installable structure, so it can be stored or opened for use according to the actual situation at the blasting site, making it more convenient to use; Second, the shielding member 300, as a barrier component to block and buffer small fragments from splashing, is prone to deformation due to impact from small fragments after a certain period of use, so the shielding member 300 can be replaced while the main structure can be reused, thereby reducing the overall cost of the blasting splash buffer structure 10; Finally, since the distance between the top plate 200 and the base 100 is adjusted by the adjusting column 500, the shielding member 300 is tightened, so the shielding member 300 can preferably be made of a material with a certain degree of flexibility. In one embodiment, the shielding member 300 can be a steel mesh structure woven from steel wire, so that the shielding member 300 can be rolled up and stored. Furthermore, in another embodiment, the shielding member 300 can also be a steel plate structure. In this embodiment, the thickness of the steel plate can range from 0.1mm to 0.3mm. Thus, the blasting anti-splash buffer structure 10 of this application can be used to protect personnel and equipment at a mine blasting site, preventing flying small fragments from endangering personnel safety and damaging blasting equipment.

[0030] like Figure 1 and Figure 3 As shown, in one embodiment, a support block 110 is provided at each end of the base 100, and the two side plates 400 are rotatably connected to the two support blocks 110 respectively.

[0031] It should be noted that, in order to facilitate the storage of the top plate 200 and the base 100, support blocks 110 are provided on the same side at both ends of the base 100. The length of the top plate 200 is less than the distance between the two support blocks 110, so that the top plate 200 can be stored between the two support blocks 110. When the side plate 400 rotates relative to the support blocks 110, the side plate 400, the top plate 200, and the base 100 can be closed together in sequence.

[0032] like Figure 1 and Figure 3As shown, in one embodiment, baffles 120 are provided on both sides of each support block 110, so that a slot is formed between the two baffles 120 of any support block 110, and the two ends of the top plate 200 are detachably accommodated in the slots of the two support blocks 110.

[0033] Thus, a baffle 120 is set on both sides of each support block 110 to limit the top plate 200. When the side plate 400 rotates relative to the support block 110 to close, the top plate 200 is blocked by the side plate 400, so that the top plate 200 is stably closed with the base 100 and the side plate 400 and will not fall out.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, side grooves 210 are respectively provided on both ends of the top plate 200. A locking block 600 is rotatably disposed in the side groove 210. A locking hole 610 is provided on the locking block 600. When the locking block 600 is subjected to force and rotates relative to the top plate 200, the adjusting column 500 passes through the locking hole 610.

[0035] It should be noted that, in order to ensure that the top plate 200 can be housed between the two support blocks 110, the length of the top plate 200 must be less than the distance between the support blocks 110. When the side plate 400 rotates to form a right angle with the base 100, the length of the top plate 200 will be less than the distance between the two side plates 400. Therefore, to ensure a reliable connection between the top plate 200 and the adjusting column 500, side grooves 210 are provided at both ends of the top plate 200, and locking blocks 600 are rotatably installed in the side grooves 210, so that the locking blocks 600 can be housed in the side grooves 210 or extend from the ends of the top plate 200. Thus, the locking blocks 600 are subjected to force to rotate relative to the top plate 200. When the axial direction of the locking hole 610 of the locking blocks 600 is aligned with the axial direction of the side plate 400, the locking blocks 600 are locked and fixed to the top plate 200, meaning that the locking blocks 600 can no longer continue to rotate upward relative to the top plate 200. At this point, the adjusting column 500 is passed through the locking hole 610, so that the adjusting column 500 and the locking block 600 are locked together. Thus, by simply rotating the adjusting column 500, the adjusting column 500 can push the top plate 200 away from the locking seat 100, thereby tightening the blocking member 300 that is hung between the base 100 and the top plate 200.

[0036] like Figure 1 and Figure 2 As shown, in one embodiment, the adjusting column 500 includes a column body 510 and a polyhedron 520. The polyhedron 520 is coaxially disposed on the column body 510. The column body 510 is screwed to the side plate 400. The polyhedron 520 is used to support the locking block 600.

[0037] It should be noted that the column 510 structure on one side of the polyhedron 520 has external threads, while the column 510 structure on the other side of the polyhedron 520 has a smooth cylindrical structure. Thus, the threaded portion is screwed to the end face of the side plate 400, and the smooth cylindrical portion passes through the locking hole 610, allowing the adjusting column 500 to be locked and fixed to the locking block 600. The outer diameter of the polyhedron 520 is larger than the outer diameter of the column 510. The polyhedron 520 holds the locking block 600, and when the polyhedron 520 is rotated under force, the top plate 200 can be moved away from the base 100 to tension the blocking member 300. Furthermore, the polyhedron 520 can be easily clamped using tools such as wrenches.

[0038] like Figure 2 and Figure 4 As shown, in one embodiment, the locking block 600 is provided with a top holding surface 620. When the locking block 600 is subjected to force and rotates relative to the top plate 200, the top holding surface 620 abuts against the inner bottom wall of the side groove 210, so that the locking block 600 is engaged with the side plate 400.

[0039] It should be noted that the locking block 600 is designed to be rotatable relative to the top plate 200. This serves two purposes: firstly, it allows the locking block 600 to extend outwards from both ends of the top plate 200, enabling the adjusting column 500 to engage with it. Secondly, when the locking block 600 is rotated and retracted into the side groove 210, the length of the top plate 200 is less than the length between the two support blocks 110, allowing the top plate 200 to be housed between them. To ensure that the locking block 600 remains stably extended away from both ends of the top plate 200 when it extends from its end, a top-holding surface 620 is provided on the locking block 600. This top-holding surface 620 abuts against the inner bottom wall of the side groove 210, securing the locking block 600 to the top plate 200. When the locking block 600 is subjected to reverse rotation, it can be retracted into the side groove 210.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, a foot 130 is provided on the side of the base 100 away from the support block 110 at both ends, and a through hole 131 is provided on the foot 130.

[0041] It should be noted that, in order to facilitate the upright installation of the blasting splash buffer structure 10 of this application, a support leg 130 is provided on the bottom side of the base 100, near both ends. Each support leg 130 has a through hole 131. Thus, by inserting a reinforcing bar into the through hole 131 and then burying the reinforcing bar underneath or welding it to another metal base, the blasting splash buffer structure 10 of this application can be installed upright. In one embodiment, each support leg 130 may have multiple through holes 131, thereby improving installation stability.

[0042] like Figure 3 and Figure 5 As shown, in one embodiment, a plurality of fastening posts 700 are provided at intervals on the base 100 and the top plate 200. A fastening groove 710 is provided on the side of the fastening post 700 away from the side plate 400. The fastening groove 710 is used to snap the cover member 300.

[0043] It should be noted that, for example, the fastening post 700 is welded to the base 100 or the top plate 200, and multiple fastening posts 700 are arranged on both sides of the base 100 and the top plate 200. Each fastening post 700 has a fastening groove 710. In this way, the fastening groove 710 is used to fasten the blocking member 300. When the adjusting post 500 rotates to push the top plate 200 away from the base 100, the fastening groove 710 locks the blocking member 300, thereby making the blocking member 300 tensioned.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. Furthermore, unless otherwise defined, in this application, a rotating connection can be understood as achieving rotating installation through a pin as an intermediate component. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
