Abstract
A kind of coal-winning machine cover plate, belong to coal-winning machine equipment technical field, even if technical problem to be solved also can not cause the cover plate come off after being to provide the fracture of a kind of cover plate set bolt, the technical scheme adopted: a kind of coal-winning machine cover plate, cover plate is arranged on miner set outside by set bolt, also comprise the first fastener and the second fastener that mutually fasten, described first fastener is arranged on the inwall of coal-winning machine cover plate, described second fastener is arranged on the outer wall of miner set, and the utility model is applied to coal-winning machine.
Description
Technical field
A kind of coal-winning machine cover plate, belongs to coal-winning machine equipment technical field.
Background technology
Coal mining unit mainly completes fully mechanized mining by spiral cutting drum.Coal-winning machine both sides are provided with several pieces of cover plates to protect the safe operation of the parts of coal-winning machine inside; but; when coal-winning machine walking coal cutting; very large friction can be produced between the cover plate of side and every layer; long operation may cause the fracture of cover plate set bolt; finally cause coming off of cover plate, the safe operation of coal-winning machine is impacted.
Utility model content
Even if technical problem to be solved in the utility model also can not cause the cover plate come off after being to provide the fracture of a kind of cover plate set bolt.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of coal-winning machine cover plate, cover plate is arranged on miner set outside by set bolt, also comprise the first fastener and the second fastener that mutually fasten, described first fastener is arranged on the inwall of coal-winning machine cover plate, and described second fastener is arranged on the outer wall of miner set.
Described first fastener and the second fastener are L tee section, are square-section after the first fastener and the second fastener fasten.
Described first fastener and the second fastener are F tee section, are square-section after the first fastener and the second fastener fasten.
Compared to the prior art the utility model has following beneficial effect.
One, cover plate is first buckled on unit by the first fastener and the second fastener, then installs set bolt again, and fall behind even if set bolt is disconnected like this, cover plate still can buckle on unit, ensure that the safe operation of coal-winning machine.
Two, the application life that cover plate after first fastener can extend cover plate is set, better protective effect can be played to coal-winning machine, and install simple and convenient, extra cost can not be increased.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of cover plate at coal-winning machine.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the partial enlarged drawing at A place in Fig. 2.
In figure, 1 is coal-winning machine, and 2 is cover plate, and 3 is set bolt, and 4 is unit, and 5 is the first fastener, and 6 is the second fastener.
Detailed description of the invention
Embodiment one
As shown in Figure 1-Figure 3, a kind of coal-winning machine cover plate, it is outside that cover plate 2 is arranged on coal-winning machine 1 unit by set bolt 3, also comprise the first fastener 5 and the second fastener 6 mutually fastened, described first fastener 5 is arranged on the inwall of coal-winning machine 1 cover plate 2, and described second fastener 6 is arranged on the outer wall of coal-winning machine 1 unit.
Described first fastener 5 and the second fastener 6 are L tee section, are square-section after the first fastener 5 and the second fastener 6 fasten.
Embodiment two
As shown in Figure 1-Figure 3, a kind of coal-winning machine cover plate, it is outside that cover plate 2 is arranged on coal-winning machine 1 unit by set bolt 3, also comprise the first fastener 5 and the second fastener 6 mutually fastened, described first fastener 5 is arranged on the inwall of coal-winning machine 1 cover plate 2, and described second fastener 6 is arranged on the outer wall of coal-winning machine 1 unit.
Described first fastener 5 and the second fastener 6 are F tee section, are square-section after the first fastener 5 and the second fastener 6 fasten.
