Technical Field
The invention belongs to the technical field of mining equipment, and particularly relates to a miner hat.
Background
When miners and other mine workers (hereinafter, referred to as miners) work in a mine tunnel or an open-air stope, the heads of the miners and other mine workers are hardly struck by hard objects such as falling or falling ores and rocks, and in a narrow tunnel, the heads of the miners are also hardly struck by other hard objects such as a support beam in the tunnel. The miner hat has the main functions of reducing impact force of hard objects such as ores, rocks, supporting beams and the like, eliminating or reducing damage to the head of a miner, namely, the impact force acting on the head of a human body is weakened by dispersing the impact force, so that the protection effect is achieved.
However, the existing miner caps have certain defects, mainly: or the production cost is too high, the popularization in the special middle and small mines of the mines is difficult, or the good protection effect cannot be achieved. For miner caps with undesirable protection effects, the main problems are that: or the hardness is not enough, the deformation is easy, and the impact of falling objects such as falling ores and the like falling from a mine field cannot be resisted; or the impact force cannot be buffered and dispersed under the impact of hard objects such as ores, rocks, supporting beams and the like, thereby indirectly causing strong shock to the head of a miner.

Middle buffer layer 3 comprises the double-deck hollow shell layer of using carbon fiber preparation, specifically is: a first hollow shell layer is formed by arranging a plurality of hemispherical hollow shells 301 made of carbon fibers in a longitudinal and transverse mode (in the embodiment, the diameter of each hollow shell 301 is 0.5 cm, the number of the hollow shells is determined according to the specific size of the miner cap, and the thickness of each upper protective layer 2 and the thickness of each lower protective layer 4 are 0.3 cm), and then a second hollow shell layer is formed by fixedly arranging one hemispherical hollow shell 301 on each row of two adjacent hemispherical hollow shells 301 (in the embodiment, the number of the hollow shells 301 of the second hollow shell layer is one less than that of the hollow shells 301 of the first hollow shell layer).
The upper protective layer 2 is made of a material (mixture) consisting of phenolic resin, epoxy resin, polyphenyl ether, silicon carbide powder, flake graphite and glass fiber; the lower protective layer 4 is made of a material (mixture) composed of phenolic resin, epoxy resin, tungsten boride powder, tetrabutyl titanate, barium sulfate powder, asbestos fiber, carboxyl liquid nitrile rubber and magnesium silicide powder. In the present embodiment, the mass percentages of the phenol resin, the epoxy resin, the polyphenylene ether, the silicon carbide powder, the flake graphite, and the glass fiber used for preparing the upper protective layer 2 are preferably 25%, 20%, 10%; the mass percentages of the phenolic resin, the epoxy resin, the tungsten boride powder, the tetrabutyl titanate, the barium sulfate powder, the asbestos fiber, the carboxyl liquid nitrile rubber and the magnesium silicide powder used for the lower protective layer 4 are preferably 25%, 20%, 10%, 5%, 10%.
The front end of the cap shell 1 is provided with a miner lamp clamping groove 5, and a miner lamp 6 is detachably fixed on the cap shell 1.
The structural and material features of one embodiment of the present invention are described in detail above with reference to the accompanying drawings, the working principle of which is further described below:
when the invention is actually used, when the mine site is impacted by falling or caving ores and other hard objects, firstly, the high-hardness upper protective layer 2 firstly bears direct impact; then, the impact force is transmitted to the intermediate buffer layer 3 with moderate strength and strong toughness, the double-layer hollow shell layer structure of the intermediate buffer layer 3 disperses and absorbs the impact force (in the case of strong impact force, the hemispherical hollow shells 301 in the double-layer hollow shell layer may crack or crush, but the impact force will be dispersed and absorbed in the process of cracking or crushing), and finally, only the remaining force is transmitted to the lower protective layer 4 with high hardness and high toughness, and the lower protective layer 4 completely absorbs the impact force.
As a simplification of this embodiment, a single hollow shell layer may also be used for the intermediate buffer layer 3.
Example 2
The basic structure of this embodiment is the same as that of embodiment 1, except that, as shown in fig. 1, 7, 8, 9, 10, 11, 12, and 13, in this embodiment, the intermediate cushion layer 3 is composed of a double-layered cylindrical shell layer made of carbon fibers, specifically: a first cylindrical shell layer is formed by longitudinally or transversely arranging a plurality of cylindrical shells 302 which are made of carbon fibers and have semicircular cross sections and arc longitudinal sections (in the embodiment, the diameter of the cylindrical shells 302 is 0.5 cm, the length and the number of the cylindrical shells are determined according to the specific size of a miner cap, and the thickness of each of the upper protective layer 2 and the lower protective layer 4 is 0.3 cm), and then, one cylindrical shell 302 with the same shape and size is fixedly arranged on every two adjacent cylindrical shells 302 to form a second cylindrical shell layer (in the embodiment, the number of the cylindrical shells 302 of the second cylindrical shell layer is one less than that of the cylindrical shells 302 of the first cylindrical shell layer).
As a simplification of the present embodiment, a single cylindrical shell layer may be used for the intermediate buffer layer 3.
Compared with embodiment 1, the present embodiment has the advantages that: the intermediate buffer layer 3 is more easily manufactured when it has the cylindrical case 302 structure, so that the intermediate buffer layer 3 can be manufactured at a lower cost and with higher efficiency in this embodiment.
