Description

Technical Field

[0001] This utility model relates to the field of blasting construction technology, specifically to a blasting protection device. Background Technology

[0002] During blasting operations, to prevent flying sand and rocks from scattering and endangering the lives and property of people in the surrounding area, protective devices are usually installed around the blasting site. Existing protective devices are usually steel barriers. By erecting steel barriers around the blasting site and setting up support frames on the steel barriers, the flying sand and rocks are blocked within the area enclosed by the steel barriers. Before the blast, all personnel are evacuated to the area enclosed by the barriers. This can prevent the flying sand and rocks generated by the blast from endangering the lives and property of people in the surrounding area.

[0003] Utility model patent CN220670351U discloses a blasting protection frame, which is installed on the ground. A main baffle is fixedly installed in the middle of the upper surface of the ground. Three vertical support frames are fixedly installed on one side of the main baffle. Three support members are fixedly installed on one side of each of the three vertical support frames. Horizontal support frames are fixedly installed on the bottom surfaces of the nine support members in groups of three. The lower surface of the middle horizontal support frame has slots on both the front and rear sides. Blocks are embedded on both the front and rear sides of one side of the upper surface of the ground. Diagonal support frames are embedded on both the front and rear sides of one side of the upper surface of the ground. Three horizontal frames are fixedly installed on the other side of the main baffle. Bamboo baffles are fixedly installed on one side of each of the three horizontal frames. Both the main baffle and the bamboo baffles have a hollow design. The main baffle is placed upside down on the ground, and the vertical support frames are placed on the main baffle, where they are engaged by grooves and protrusions. After initial positioning, the horizontal support frame is placed on top of the vertical support frame and fixed to the vertical support frame with the first fixing bolt. The main baffle is then erected, and the inclined support frame is inserted into the slot on the horizontal support frame, with the other end inserted into the ground. The obstruction block increases the force that the inclined support frame can support, allowing the main baffle to withstand greater impact. A horizontal frame is fixedly installed at one end of the main baffle, and a bamboo baffle is initially fixed at one end of the horizontal frame by engaging with the horizontal slot, and then fixed with the second fixing bolt. The bamboo baffle can absorb the force of the gravel hitting the baffle, making the frame more resilient and effectively extending its service life. In this patent, the main baffle and the inclined support frame form a triangular support structure placed on the ground. However, during use, the connection stability between the entire device and the ground is poor, and it is easy to tilt away from the inclined support frame, thus affecting the containment effect of flying rocks during blasting.

Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] In one embodiment, see Figure 1 The present invention provides a blast protection device, comprising a protection component and a support component.

[0023] The protective assembly includes multiple sets of interlocking protective plates 1, buffer members 2 set on the protective plates 1, and connecting members 3 between adjacent protective plates 1; the support assembly includes a stabilizing member 4 hinged to the bottom end of the protective plate 1, and a support member 5 hinged to the middle of the protective plate 1.

[0028] Further, see Figure 1 , 3The connector 3 includes a snap-fit ​​groove 301 and a snap-fit ​​connector 302 provided on the edge of the protective plate 1. In the vertical direction, adjacent protective plates 1 are connected by the snap-fit ​​groove 301 and the snap-fit ​​connector 302. A connecting sleeve 13 is provided on the side edge of the protective plate 1. A connecting screw 14 is provided inside the connecting sleeve 13. In the horizontal direction, adjacent protective plates 1 are threadedly connected by the connecting screw 14 and the connecting sleeve 13.

[0029] Preferably, the cross-section of the snap-fit ​​groove 301 and the snap-fit ​​connector 302 in the vertical direction is a "T" shaped structure, and the snap-fit ​​groove 301 and the snap-fit ​​connector 302 are located at the bottom and top of the protective plate 1, respectively.

During the installation of the protective plate 1, only two sets of protective plates 1 need to be equipped with stabilizing plates 401. These two sets of protective plates 1 are located on the ground and at the lower left and lower right corners of the spliced ​​protective plate 1. After the stabilizing plate 401 is flipped to be perpendicular to the protective plate 1, the first locking pin 602 is rotated into the first locking screw hole, thereby fixing the position between the stabilizing plate 401 and the protective plate 1. The stabilizing plate 401 increases the contact area between the protective plate 1 and the ground, improving the stability of the protective plate 1.

[0036] Further, see Figure 1 , 3 The support member 5 includes a support frame 501 mounted on the protective plate 1 and a support rod 502 mounted inside the support frame 501. A plug-in rod 19 is movably mounted on the support rod 502. Under the action of external force, the plug-in rod 19 moves away from the support rod 502 and then inserts into the ground.

[0040] Preferably, the support frame 501 is provided with a second locking screw hole 702, the support rod 502 is provided with a second locking hole, and the second locking stud is connected to the second locking screw hole 702 by threads.

[0041] Further, see Figure 1 The reinforcing member 8 includes a reinforcing plate, which is movably mounted on the plug rod 19. The plug rod 19 is provided with retaining rings 24 located on both sides of the reinforcing plate.

[0042] Preferably, the reinforcing plate has through holes, which are inclinedly disposed on the reinforcing plate.

[0043] In the above setup, after the protective plate 1 is assembled and supported on the ground, the support rod 502 is set on two of the protective plates 1. To ensure the support effect, the two protective plates 1 with the support rod 502 can be installed in the middle or upper part of the assembled protective plate 1. By unfolding the support rod 502 and rotating the second locking pin 701 into the second locking hole, the angle between the support rod 502 and the protective plate 1 can be fixed. At this time, the plug rod 19 at the end of the support rod 502 is tilted towards the ground. Rotating the plug rod 19 causes the reinforcing plate to move in one direction. The plug tip 23 on the plug rod 19 is inserted into the ground, and the reinforcing plate abuts against the ground. The setting of the retaining ring 24 allows the reinforcing plate to be installed on the plug rod 19. At the same time, it also ensures that the reinforcing plate and the plug rod 19 will not separate when the plug rod 19 is rotated. The plug tip 23 and the connection between the reinforcing plate and the ground provide support for the support rod 502. The support rod 502 and the stabilizing plate 401 are respectively supported on both sides of the protective plate 1, thereby ensuring that the protective plate 1 is stably installed on the ground.
