[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown:

[0030] Embodiment 1: The present invention provides a metal mining safety protection device, comprising:

[0031] The support and protection mechanism 1 comprises a support frame assembly 11 and a support leg assembly 12 fixedly mounted on the bottom of the support frame assembly 11;

[0032] The support frame assembly 11 includes an arc-shaped support plate 111 , and the lower ends of both sides of the arc-shaped support plate 111 are fixedly connected to side support plates 112 ;

[0033] The arc-shaped support plate 111 and the side support plate 112 are formed by bending steel plates in one piece;

[0034] Among them, when the ore on the top of the mine falls, the arc support plate 111 can play a protective role, the side support plate 112 can protect the side, and the support leg assembly 12 can play a supporting role, providing space for the staff to move. The arc support plate 111 and the side support plate 112 are formed by bending the steel plate into one piece, and there is a certain amount of space for movement at the bottom. When a large piece of mine collapses and buries the arc support plate 111, the temporary safety of the miners can be guaranteed through this space, thereby buying time for rescue.

[0035] Specifically, the support leg assembly 12 includes several support leg bodies 121, the bottoms of several support leg bodies 121 are fixedly connected with moving wheels 122, and adjacent groups of support leg bodies 121 are also fixedly connected with support rods 123; wherein, adjacent support leg bodies 121 are fixedly connected by support rods 123, thereby enhancing the overall stability of the support leg assembly, preventing tipping or shaking in the complex environment of the mine, and ensuring that the protective device can be firmly supported in the mine.

[0036] The supporting leg body 121 is fixedly mounted on the bottom of the arc-shaped supporting plate 111 .

[0037] Specifically, the upper side of the support frame assembly 11 is also slidably connected to a protective frame assembly 13;

[0038] The protection frame assembly 13 includes an arcuate surface 131 and a spring 132 . The bottom of the arcuate surface 131 is fixedly connected to a limiting rod 133 .

[0039] Specifically, the limiting rod 133 is limitedly slidably engaged on the arc-shaped support plate 111 , and the spring 132 drives the arc-shaped arch surface 131 upward away from the arc-shaped support plate 111 .

[0040] As can be seen from the above, by installing movable wheels 122 at the bottom of the support leg body 121, the entire protective device can be flexibly moved within the mine, making it easy to adjust its position according to the mining progress and mine conditions, thereby improving work efficiency and flexibility. The curved arch surface 131 of the protective frame assembly 13 cooperates with the curved support plate 111 to form a double layer of protection for the mine roof. When ore falls, the impact is first borne by the curved arch surface 131, further reducing the possibility of the ore directly impacting the curved support plate 111 and enhancing the overall protective capability. The design of spring 132 ensures that the curved arch surface 131 has a certain cushioning and shock-absorbing effect when impacted, reducing the damage caused by the impact force to the miners and the device itself.

[0041] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the support rod 123 is further fixedly connected to a shaft bracket 124; the shaft bracket 124 is fixedly connected to the support rod 123, providing a rotation fulcrum for the connecting mechanism 2;

[0042] It also includes a connecting mechanism 2, which includes a first connecting rod assembly 21 and a second connecting rod assembly 22 that are respectively rotatably embedded in a group of shaft frames 124, and a connecting assembly 23 is also limitedly and slidably embedded on one side of the second connecting rod assembly 22; wherein the first connecting rod assembly 21 and the second connecting rod assembly 22 are both rotatably embedded through the shaft frame 124, so that the two can rotate relative to each other.

[0043] Specifically, the first connecting rod assembly 21 comprises a first connecting rod body 211, and a handle one 212 is fixedly connected to the outer side of the first connecting rod body 211;

[0044] The second connecting rod assembly 22 comprises a second connecting rod body 221, and a handle two 222 is fixedly connected to the outer side of the second connecting rod body 221;

[0045] The connecting assembly 23 comprises a connecting column 231, a threaded rod 232 is fixedly connected to one side of the connecting column 231, a limiting ring 233 is fixedly connected to the other side of the connecting column 231, a rotating handle 234 is fixedly connected to the outer side of the connecting column 231, and a spring two 235 is further sleeved on the outer side of the connecting column 231; wherein the threaded rod 232 is used for being screwedly clamped with the first connecting rod body 211, and the limiting ring 233 is used for being limitedly slid on the second connecting rod body 221; the rotating handle 234 is convenient for rotating the connecting column 231, and the threaded rod 232 is further driven to rotate; and the spring two 235 plays a role of resetting.

[0046] Specifically, the connecting column 231 is limitedly slid and clamped on the second connecting rod body 221 through the limiting ring 233, the threaded rod 232 can be screwedly clamped on the first connecting rod body 211, and the spring two 235 drives the limiting ring 233, the connecting column 231 and the threaded rod 232 to drive the threaded rod 232 to move away from the first connecting rod body 211.

[0047] As can be known from the above, when the rock falls on the top of the mine, the first connecting rod body 211 and the second connecting rod body 221 are rotated to be oppositely arranged, the rotating handle 234 is moved and rotated to make the threaded rod 232 be screwedly clamped on the first connecting rod body 211, and at the same time, the spring two 235 is compressed, the handle one 212 and the handle two 222 can be used to conveniently push the whole device to move, so that the dangerous area is evacuated, and when the rotation makes the threaded rod 232 be separated from the first connecting rod body 211, the resetting of the spring two 235 makes the connecting column 231 drive the threaded rod 232 to retract.

[0048] Application process:

[0049] Installation and preparation:

[0050] Firstly, the metal mine exploitation safety protection device is installed at a suitable position in the mine.

[0051] Normal operation:

[0052] When the miners are performing exploitation operation, the device can be used as a temporary safety protection barrier to protect the miners from being injured by the rock falling from the top.

[0053] The arc-shaped support plate 111 and the side support plate 112 together form a solid protective structure, and the arc-shaped arch surface 131 of the protective frame assembly 13 provides an additional protective layer, further enhancing the protective effect.

[0054] Responding to emergencies:

[0055] When a rockfall or other emergency occurs at the top of a mine, miners need to evacuate quickly to a safe area.

[0056] At this point, the miner can rotate the first connecting rod assembly 21 and the second connecting rod assembly 22 so that they are opposite each other, and then rotate the rotating handle 234 to screw the threaded rod 232 onto the first connecting rod body 211. This operation locks the two connecting rod assemblies together, enhancing the overall stability of the device and making it easier for the miner to push the entire device to evacuate.

[0057] During the pushing process, handle one 212 and handle two 222 provide convenient gripping points, allowing the miner to easily control the direction and speed of the device.

[0058] When the device is evacuated to a safe area, the miner can rotate the rotary handle 234 to disengage the threaded rod 232 from the first connecting rod body 211. At this time, the second spring 235 will drive the connecting column 231 and the threaded rod 232 to retract and return to the initial state for the next use.

[0059] Maintenance and Adjustment:

[0060] After each use, the unit should be thoroughly inspected to ensure that all parts are intact and free of fallen ore and dust.

[0061] According to the specific conditions of the mine and the progress of mining, the position and angle of the device are adjusted in time to ensure that it can always provide effective safety protection.
