Description

Technical Field

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

[0002] Metals are one of the most important raw materials in our daily life and production activities. Metals are mainly produced by smelting ores, which requires mining. Mining requires blasting rocks, which is divided into large-scale mine blasting and micro-blasting in mine tunnels. When blasting inside a mine tunnel, workers need to be protected to prevent flying debris from injuring them.

[0003] Existing protective devices are relatively simple in structure, mostly using locally sourced materials or simple protective panels. Such protective measures not only fail to protect workers, but also cause secondary injuries due to material issues, resulting in a persistently high risk level for workers.

[0004] Therefore, it is necessary to propose a rock blasting protection device for mining construction. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rock blasting protection device for mining construction, which effectively provides protection for workers and is easy to disassemble and carry, thus solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a rock blasting protection device for mining construction, comprising an L-shaped protection block and an arc-shaped protection block:

[0007] The L-shaped protective block has side sliding grooves on both sides, and a connecting slider is slidably connected inside the side sliding grooves.

[0008] An arc-shaped protective block is fixedly connected to the outer side of the connecting slider. A second hinge block is fixedly connected to the upper and lower ends of the inner side of the arc-shaped protective block. A support block is hinged inside the second hinge block. A snap-in block is fixedly connected to the back side of the L-shaped protective block. The other end of the support block snaps into the inside of the snap-in block. A first hinge block is fixedly connected to both ends of the back side of the L-shaped protective block. A telescopic rod is hinged inside the first hinge block. A support leg is hinged to the other end of the telescopic rod.

[0009] Preferably, the telescopic rod includes a fixed rod and an output rod, and both the fixed rod and the output rod have limit grooves, with a limit rod inserted at the overlapping point of the two sets of limit grooves.

[0010] Preferably, support blocks are fixedly connected to the four corners of the lower surface of the L-shaped protective block.

[0011] Preferably, the support blocks are provided in four sets, and the four sets of support blocks are arranged in pairs on the two sets of arc-shaped protective blocks.

[0012] Preferably, the support block and the locking block are on the same horizontal line, and the number of support blocks and locking blocks is the same.

[0013] Preferably, a connecting post is installed at the middle of the back side of the L-shaped protective block, and a limiting round block is threaded to the other end of the connecting post. A slot is opened at the middle of the arc-shaped protective block, and the inside of the slot is inserted into the outside of the connecting post.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of rock blasting protection device for mining construction consists of two sets of arc-shaped protective blocks installed on both sides of an L-shaped protective block. Simultaneously, one end of a support block hinged to the arc-shaped protective block is engaged with a locking block located inside the L-shaped protective block, forming a semi-arc protective device. The arc-shaped surface effectively disperses the force generated by rock blasting, improving the protective effect. Through the extension of the telescopic rod, the other end of the telescopic rod can be supported on the ground, creating a triangular stable structure between the L-shaped protective block and the telescopic rod. This structure effectively resists the impact force from rock blasting, further enhancing the protective effect. Furthermore, the L-shaped and arc-shaped protective blocks are detachable, facilitating installation and storage. Attached Figure Description

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.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A rock blasting protection device for mining construction includes an L-shaped protective block 1 and an arc-shaped protective block 2.

[0027] Both sides of the L-shaped protective block 1 are provided with side sliding grooves 130, and a connecting slider 210 is slidably connected inside the side sliding grooves 130.

[0028] An arc-shaped protective block 2 is fixedly connected to the outer side of the connecting slider 210. A hinge block 4 is fixedly connected to the upper and lower ends of the inner side of the arc-shaped protective block 2. A support block 410 is hinged inside the hinge block 4. A snap-in block 420 is fixedly connected to the back side of the L-shaped protective block 1. The other end of the support block 410 is snapped into the inside of the snap-in block 420. A hinge block 3 is fixedly connected to both ends of the back side of the L-shaped protective block 1. A telescopic rod 310 is hinged inside the hinge block 3. A support leg 320 is hinged to the other end of the telescopic rod 310. The telescopic rod 310 includes a fixed rod and an output rod. A limit groove 330 is opened on both the fixed rod and the output rod. A limit rod 340 is inserted at the overlapping part of the two sets of limit grooves 330. A support block 410 is fixedly connected to the four corners of the lower surface of the L-shaped protective block 1.

[0029] In use, the L-shaped protective block 1 is inserted into the ground through the insertion post 140 and placed stably on the ground. The arc-shaped protective block 2 is inserted into the side sliding groove 130 opened on the side of the L-shaped protective block 1 through the connecting slider 210. At this time, the telescopic rod 310 is rotated upward and the support block 410 is rotated so that the other end of the support block 410 is engaged with the locking block 420. Then, the telescopic rod 310 is rotated downward and the length between the fixed rod and the output rod of the telescopic rod 310 is adjusted so that the support leg 320 hinged at the other end of the telescopic rod 310 contacts the ground. After adjusting the length, the length is limited by inserting the limiting rod 340 into the limiting groove 330, thereby completing the deployment of the device.

[0030] As a preferred technical solution of this utility model, the support block 410 is provided in four sets, and the four sets of support blocks 410 are arranged in pairs on the two sets of arc-shaped protective blocks 2.

[0031] As a preferred embodiment of this utility model, the support block 410 and the locking block 420 are on the same horizontal line, and the number of support blocks 410 and locking blocks 420 is the same.

[0032] As a preferred technical solution of this utility model, a connecting post 110 is installed at the middle of the back side of the L-shaped protective block 1, and the other end of the connecting post 110 is threadedly connected to a limiting round block 120. A groove 220 is opened at the middle of the arc-shaped protective block 2, and the inside of the groove 220 is inserted into the outside of the connecting post 110.

[0033] During disassembly, the support of the telescopic rod 310 is released, and the telescopic rod 310 is rotated upward. Then, the connection between the telescopic rod 310 and the locking block 420 is released, and the arc-shaped protective block 2 is pushed upward, so that the arc-shaped protective block 2 is disengaged from the L-shaped protective block 1. The telescopic rod 310 is rotated downward, so that the telescopic rod 310 is parallel to the back side of the L-shaped protective block 1. Since the arc-shaped protective block 2 has a slot 220, the arc-shaped protective block 2 is inserted into the connecting column 110 through the slot 220. The other set of arc-shaped protective blocks 2 is handled in the same way. Then, the arc-shaped protective block 2 is limited by rotating the limiting block 120, thereby completing the disassembly of the device.
