Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a safety protection device for open-pit mines. Background Art

[0002] Open-pit mining involves removing the soil and surrounding rock covering the ore body and directly extracting the ore from the exposed ore body. Open-pit mining is advantageous over underground mining when the ore body is shallow or has surface outcrops. Open-pit mining offers advantages such as convenience, safety, wide coverage, high equipment mobility, and flexible personnel movement.

[0003] According to a publicly disclosed open-pit mine blasting flying rock safety protection device (Announcement No.: CN219914210U), in the above application, the rotation of the threaded rod will drive the two insertion rods to be inserted into the positioning grooves respectively, so that the mounting block is clamped and fixed in the mounting groove, thereby completing the installation of the protective plate. The open-pit mine blasting flying rock safety protection device facilitates the installation of the protective plate and is more convenient to assemble. A positioning rod is movably inserted in the connecting block, and the bottom end of the positioning rod is designed as a pointed end, which facilitates the insertion of the positioning rod into the soil, fixes the support rod, and makes the placement of the device more stable.

[0004] However, although this device solves the problems of installing and fixing the protective plates to a certain extent, it still has some limitations in practical application. In particular, when facing larger protection areas, the protective plates in this device are not easy to dock with each other, resulting in limited use in situations where large areas need to be protected, such as large open-pit mines. The protective plates in this device are relatively simple in design and lack a flexible docking mechanism, making the operation complicated and inefficient when multiple protective plates need to be spliced together to cover a larger area. In addition, due to loose docking, there is also the risk of flying rocks passing through the gaps, thereby reducing the overall protection effect. Utility Model Content

The end of the spring 2 65 away from the L-shaped rod 64 is fixed to the surface of the protective plate 1. A sliding groove 66 is provided on the surface of the L-shaped rod 64, and a block 68 is slidably connected to the inner wall of the sliding groove 66. A spring 3 67 is fixed on the surface of the block 68, and the end of the spring 3 67 away from the block 68 is fixed to the inner wall of the sliding groove 66. The connecting component 6 also includes a limiter 69. Pressing the L-shaped rod 64 so that the L-shaped rod 64 is inserted into the socket 1 62 and the socket 2 63 can fix the protective plates 1.

[0022] The limiting member 69 includes a fixed plate 690, which is fixed to the surface of the protective plate 1. A fixed block 691 is fixed to the surface of the fixed plate 690. A sliding block 692 is slidably connected to the surface of the fixed plate 690. A magnet 693 is fixed to the surface of the protective plate 1. The end of the clamping block 68 away from the spring 3 67 is set as an inclined surface, the side of the fixed block 691 away from the sliding block 692 is set as an inclined surface, and the side of the sliding block 692 away from the fixed block 691 is set as an inclined surface. When the L-shaped rod 64 and the clamping block 68 move, the side of the clamping block 68 away from the inclined surface contacts the side of the fixed block 691 away from the inclined surface. The fixed block 691 can limit the card block 68 and the L-shaped rod 64. When the protective plate 1 needs to be separated, press the L-shaped rod 64 again. When the card block 68 moves away from one side of the fixed block 691, the spring 2 65 is released, and the L-shaped rod 64 and the card block 68 drive the sliding block 692 to move closer to the fixed block 691. When the surface of the sliding block 692 fits the surface of the fixed block 691, the card block 68 moves along the surface of the sliding block 692 and the fixed block 691, thereby releasing the limit of the card block 68. At this time, the L-shaped rod 64 disengages from the socket 1 62 and the socket 2 63, and the protective plate 1 can be separated normally.

[0023] Ground nails 2 are installed on the surface of the protective plate 1, and an L-shaped frame 3 is fixed on the side of the protective plate 1 away from the protective cover 70. A buffer plate 4 is slidably connected to the inner side of the L-shaped frame 3. A spring 5 is fixed on the surface of the buffer plate 4, and one end of the spring 5 away from the buffer plate 4 is fixed to the surface of the protective plate 1. By setting the buffer plate 4 and spring 5, the buffer plate 4 can reduce the impact of flying stones on the protective plate 1.

[0024] The protective cover 70 is fixed on the surface of the protective plate 1. The surface of the protective cover 70 is hinged with a protective cover 71. The surface of the protective cover 71 is fixed with a torsion spring 72. The end of the torsion spring 72 away from the protective cover 71 is fixed to the surface of the protective cover 70. The protective cover 71 blocks the L-shaped rod 64 to avoid accidental contact with the L-shaped rod 64, causing the L-shaped rod 64 to disengage from the socket 1 62 and the socket 2 63, and causing the protective plates 1 to disengage.

[0025] When the protective plates 1 need to be docked, the plug 60 is installed in the slot 61. At this time, the socket 1 62 is parallel to the socket 2 63. At this time, the protective cover 71 is opened and the L-shaped rod 64 is pressed. At this time, the spring 2 65 is compressed. At this time, the L-shaped rod 64 is inserted into the socket 1 62 and the socket 2 63, and the protective plates 1 can be connected and fixed. At the same time, when the L-shaped rod 64 moves, the block 68 is synchronously driven to move. When the inclined surface of the block 68 contacts the inclined surface of the fixing block 691, the L-shaped rod 64 is pressed. When the block 68 enters the slide 66, the spring 3 67 is compressed. When the block 68 is located on the side of the fixed block 691 close to the sliding block 692, the spring 3 67 is released. At this time, the side of the block 68 away from the inclined surface collides with the side of the fixed block 691 away from the inclined surface, so that the fixed block 691 can limit the block 68 and the L-shaped rod 64. At this time, the personnel releases the protective cover 71, the torsion spring 72 is released, and the protective cover 71 is reset to block the L-shaped rod 64 to avoid accidents. When the L-shaped rod 64 is accidentally touched, the L-shaped rod 64 disengages from the first socket 62 and the second socket 63, and the protective plate 1 is separated. When the protective plate 1 needs to be separated, the protective cover 71 is opened again and the L-shaped rod 64 is pressed again. At this time, the inclined surface of the block 68 contacts the surface of the sliding block 692. When the block 68 moves away from one side of the fixed block 691, the spring 2 65 is released, and the L-shaped rod 64 and the block 68 drive the sliding block 692 to move closer to the fixed block 691. When the surface of the sliding block 692 is in contact with the surface of the fixed block 691, the block 68 moves along the surface of the sliding block 692 and the fixed block 691, thereby releasing the limit of the block 68. At this time, the L-shaped rod 64 disengages from the first socket 62 and the second socket 63, and the protective plate 1 can be separated normally. At the same time, through the provided buffer plate 4, when it is hit, the spring 1 5 is compressed and released, so that the buffer plate 4 can reduce the impact of flying stones on the protective plate 1, and at the same time, the protective plate 1 can be fixed through the ground nail 2.
