DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0024] A mining engineering blasting protection device, see Figures 1 to 5, including a load-bearing plate 1, a slider 10, a baffle 4 and an insert plate 14. The bottom of the load-bearing plate 1 is fixedly connected to six support frames 12 in a circular array, and the top edge of the load-bearing plate 1 is fixedly connected to a steel structure frame 3 in a circular array. The baffle 4 is installed on the inner side of the steel structure frame 3 and is tightly attached to the steel structure frame 3. Two insert plates 14 are vertically movably inserted on the front and back sides of the top of the load-bearing plate 1 inside the baffle 4. The openings on the left and right sides of the steel structure frame 3 are equipped with warehouse doors 15 through hinges. A central groove 5 is provided in the center of the top of the load-bearing plate 1. Open the movable plate 6 and follow the central warehouse to enter the space below, and manually lift the insert plate 14 to leave from the bottom of the load-bearing plate 1. The warehouse door 15 is deformed or blocked, making it difficult to open and unable to enter or exit.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, steps 2 are fixedly connected to the left and right sides of the load-bearing plate 1, and the height of the steps 2 is consistent with the support frame 12, which facilitates the fixation of the load-bearing plate 1, and the steps 2 and the support frame 12 raise the load-bearing frame, and the space formed below is convenient for passage.

[0026] It is worth noting that if Figure 5 As shown, the inserting plate 14 is perpendicular to the surface of the load-bearing plate 1, and a plurality of pins 141 are fixedly connected to the bottom of the inserting plate 14. The pins 141 can increase the stability of the inserting plate 14 during the insertion process, and when the inserting plate 14 is inserted into the ground, the top of the inserting plate 14 will be higher than the top surface of the load-bearing plate 1, and the main function of the inserting plate 14 is to block the entry of stones so that the space below the load-bearing plate 1 can pass normally.

[0027] It is worth noting that if Figure 3 As shown, a movable plate 6 is installed at the edge of the central groove 5 through a hinge. The movable plate 6 can be closed when not in use, so that the surface of the load-bearing plate 1 remains flat, which is convenient for people to move around.

[0028] It is worth noting that if Figure 2 As shown, a fixed plate 13 is fixedly connected between the two support frames 12 at the horizontal position of the ladder 2. The fixed plate 13 is immovable and its main function is to cooperate with the plug plate 14 to block the space below the load-bearing plate 1 to prevent falling rocks from outside.

[0029] Two slide grooves 7 are provided on the left and right sides of the top surface of the load-bearing plate 1. The surface of the slide groove 7 is slidably connected to a slider 10. The top of the slider 10 is fixedly connected to a push plate 11. The bottom of the slider 10 is located below the load-bearing plate 1, and the side surface of the slider 10 facing the center of the load-bearing plate 1 is fixedly connected to the telescopic end of the electric push rod 9. The other end of the electric push rod 9 is fixedly connected to the side wall surface of the support block 8 at the bottom of the load-bearing plate 1. When the electric push rod 9 is started, it drives the slider 10 to move along the slide groove 7, allowing the push plate 11 to push away the fallen rocks blocked by the outside of the baffle 4, thereby facilitating the opening of the warehouse door 15.

[0030] It is worth noting that if Figure 1 and Figure 3 As shown, the push plate 11 is located below the warehouse door 15, and the curvature of the push plate 11 is consistent with the curvature of the warehouse door 15. When not in use, the push plate 11 and the warehouse door 15 can just block the openings at both ends of the steel structure frame 3, so that the steel structure frame 3 forms a whole, which is convenient for withstanding impact and preventing the entry of falling rocks.

[0031] When the doors 15 on both sides cannot be opened, the movable plate 6 can be opened to enter the space below along the central warehouse and manually lift the inserting plate 14 to leave from the bottom of the load-bearing plate 1, avoiding the deformation or blockage of the door 15 due to strong impact, which makes it difficult to open and enter after blasting.
