Description
Technical Field
The utility model relates to a colliery is supporting articles for use technical field in the pit, concretely relates to special protection network in colliery.
Background
The protective net used by the underground hydraulic support for the mine is mostly made of hard steel nets and fixed between two front upright posts of the hydraulic support, and is used for preventing the coal briquettes which are collapsed during coal mining work from endangering the safety of workers, the collapsed coal briquettes often fly into a pedestrian passage from the upper sides of the hard steel nets to endanger the safety of the workers, and the hard steel nets of the structure cannot protect the hydraulic upright posts, so that the surface coatings of the hydraulic upright posts are easily damaged by the collapsed coal briquettes.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a special protection network in colliery.
For solving the technical problem, the utility model provides a technical scheme is a special protection network in colliery, including the dictyosome, the dictyosome both sides are all installed and are equipped with the bracing piece, bracing piece body of rod outer peripheral face evenly is equipped with the through-hole along the axis direction, through U type frame fixed connection between the adjacent dictyosome, adjacent bracing piece body of rod through-hole is inserted respectively at U type frame both ends.
As an improvement, the net body is formed by arranging spiral steel wire bars in parallel, steel wire rings between the spiral steel wire bars are mutually lapped, and meshes of the net body form a prismatic structure.
As an improvement, the end part of the U-shaped frame penetrates through the through hole and then is in threaded connection with the nut.
Compared with the prior art, the utility model the advantage lie in:
simple structure, easy production and manufacture, excellent net body elasticity and convenient field assembly and installation.

Detailed Description
The following describes the special protective net for coal mine in further detail with reference to the accompanying drawings.
With reference to the accompanying drawings 1-5, the special protective net for the coal mine comprises a net body 1, supporting rods 2 are arranged on two sides of the net body 1, through holes 201 are uniformly formed in the outer peripheral surfaces of the rod bodies of the supporting rods 2 along the axis direction, adjacent net bodies 1 are fixedly connected through U-shaped frames 3, and the two ends of each U-shaped frame 3 are respectively inserted into the through holes 201 of the rod bodies of the adjacent supporting rods 2.
As a preferred embodiment of this embodiment, the net body 1 is formed by arranging the spiral steel wire bars 101 in parallel, the steel wire rings between the spiral steel wire bars 101 are overlapped, and the meshes of the net body 1 form a prismatic structure.
In the preferred embodiment of the present invention, the end of the U-shaped frame 3 is threaded with the nut 4 after penetrating through the through hole 201.
The utility model discloses when concrete implementation, during the installation combination, insert the spiral wire reinforcement 101 inside of 1 both sides of dictyosome with bracing piece 2 respectively, then connect adjacent bracing piece 2 through U type frame 3, use the nut to fix at U type frame both ends, after the installation combination is accomplished, install the dictyosome in the canopy top or the tunnel both sides that need be strutted.
The present invention and its embodiments have been described above, but the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
