Described colliery blasting blindage, described impact-resistant panels comprises two vertical tubes, how with transverse tube and steel plate, how with the two ends of transverse tube respectively with two vertical tubes to opposite, be connected to form the framework of " order " character form structure, steel plate is arranged on the rear portion of " order " glyph framework.
Described colliery blasting blindage is provided with the angle bar of all standing in " order " glyph framework gap of steel plate front portion, described angle bar be opening outwardly.
Described colliery blasting blindage, described lock rail device comprises inverted U-shaped card, bolt, the top of inverted U-shaped card is fixedly connected with the lower surface, both sides of impact-resistant panels and the lower end of inclined support bar is connected, on the block two side of inverted U-shaped card bottom, be respectively equipped with screw, two bolt difference connecting screw holes, the head of described two bolts outwardly.
An application for colliery blasting blindage, described colliery blasting blindage is applicable to have the coal mine of track.
By above-mentioned disclosure, the invention has the beneficial effects as follows:
Colliery blasting blindage of the present invention, by impact-resistant panels and inclined support bar are fixed on the track under mine, utilize the strength of track to obtain the firm anti-impact force of impact-resistant panels, described angle bar makes the spoil dynamics of splashing obtain partly dissolving, obtained the object that the larger anti-spoil splashing impacts, effectively reduced workman and be subject to the risk that spoil injures; Staff operation is convenient in the present invention, and have safe, easy to use, reduce the advantages such as cost of labor.
[accompanying drawing explanation]
Fig. 1 is perspective view of the present invention;
Fig. 2 is impact-resistant panels structural representation of the present invention;
In the drawings: 1, transverse tube; 2, steel plate; 3, U-shaped seat; 4, axle; 5, vertical tube; 6, inclined support bar; 7, inverted U-shaped card; 8, bolt; 9, screw; 10, block; 11, angle bar.
[specific embodiment]
Below in conjunction with embodiment, the present invention is further detailed; The following examples are not for restriction of the present invention, and only, as supporting to realize mode of the present invention, any equivalent structure in technological frame disclosed in this invention is replaced, and is protection scope of the present invention;
Colliery blasting blindage described in 1 or 2 by reference to the accompanying drawings, comprise impact-resistant panels, lock rail device and inclined support bar 6, described impact-resistant panels comprises two vertical tubes 5, many with transverse tube 1 and steel plate 2, many two ends with transverse tube 1 respectively with two vertical tubes 5 to opposite, be connected to form the framework of " order " character form structure, steel plate 2 is arranged on the rear portion of " order " glyph framework, in " order " glyph framework gap of steel plate 2 front portions, be provided with the angle bar 11 of all standing, described angle bar 11 be opening outwardly, on two vertical tube 5 lower surfaces of impact-resistant panels, be respectively equipped with lock rail device, on the rear of the both sides, top of impact-resistant panels, be respectively equipped with U-shaped seat 3, the upper end of two inclined support bars 6 is by the axle 4 two U-shaped seats 3 that are articulated and connected, in the lower end of two inclined support bars 6, be respectively equipped with lock rail device.
Described lock rail device comprises inverted U-shaped card 7, bolt 8, the top of inverted U-shaped card 7 is fixedly connected with the lower surface, both sides of impact-resistant panels and the lower end of inclined support bar 6 is connected, on block 10 two sides of inverted U-shaped card 7 bottoms, be respectively equipped with screw 9, two bolt 8 difference connecting screw holes 9, the head of described two bolts 8 outwardly.
Colliery blasting blindage of the present invention is particularly useful for having the coal mine use of track.
Implement colliery blasting blindage of the present invention, the angle bar 11 of impact-resistant panels is towards bursting work face, the inverted U-shaped card 7 of two transverse tubes of impact-resistant panels, 1 lower end lock rail device is enclosed within on bull headction, utilize bolt 8 locking i-beam tracks, the angular adjustment of inclined support bar 6 is good, the inverted U-shaped card 7 of inclined support bar 6 lower end lock rail devices is enclosed within on bull headction, utilizes bolt 8 locking i-beam tracks, makes inclined support bar 6 and impact-resistant panels be formed into character form structure; Inclined support bar 6 of the present invention is used one-inch galvanized pipe to process, the mode that is articulated and connected of inclined support bar 6 and impact-resistant panels, adjustment angle that can be suitable according to different terrain is stronger for different terrain applicability; By adjusting the inclination angle size of impact-resistant panels, can avoid on the one hand the straight line shock of spoil, also can avoid on the other hand the spoil of vertical drop to injure personnel by a crashing object, shielding space is sufficient; The present invention is when rock drift blasting operation, and fireman and warning people hide and after blowing out, hide into impact-resistant panels blindage rear portion, and other staff hide near the chamber beyond warning point, the generation that the spoil of can effectively avoiding flying out is hurted sb.'s feelings.
