Description
Technical field
The utility model relates to a kind of mine coal eye locking device, particularly relates to the pneumatic envelope eye device of a kind of pulling-tray type.
Background technology
The safety management of colliery underground coal eye is the important guarantee that coal mine downhole safety is produced, and not in place because of the management of coal eye in coal production, particularly the coal eye is suitable for reading often occurs because protecting the phenomenon of casualty accident that causes not in place.Therefore in coal production, must carry out the management to the coal eye, especially need interim personal safety of sealing eye guarantee operating personnel at belt parking maintenance or head unloading.The locking device that under the coal mine coal eye is adopted at present is the hoisting type cover plate, although the hoisting type cover plate can be realized temporary enclosed to the coal eye, but have following not enough place: showing on the one hand to fall behind under the hoisting type cover plate also needs manually to promote the hoisting type cover plate and the coal eye could be sealed, operating personnel can only stand in the edge work of coal eye and can not leave coal eye edge and realize remote-controlled operation, therefore not only waste of manpower but also have hidden danger; On the other hand because the hoisting type cover plate is in the top of coal eye after being pulled up always, the process that the coal that transports on the belt during conveyor operation and spoil fall into the coal eye has the sub-fraction coal or spoil is pounded on the hoisting type cover plate, the hoisting type cover plate of being pounded by coal or spoil for a long time is damaged and lose the function of sealing coal eye easily, so need often to upgrade the hoisting type cover plate, waste to a great extent raw material and artificial.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, provides a kind of simple in structure, easy for installation and can realize the pneumatic envelope eye device of remote operated pulling-tray type.
For achieving the above object, the utility model provides the pneumatic envelope eye device of a kind of pulling-tray type to comprise coal eye double-edged fine-toothed comb, cover plate and cylinder, the both sides of described cover plate are respectively arranged with two pulleys, are provided with the dead bolt that is connected with the piston rod top of cylinder in the lower surface of cover plate; The coal eye both sides that described coal eye double-edged fine-toothed comb covers are provided with the track corresponding with the pulley of cover plate both sides; The ground of described cylinder and trapped orbit is fixed, and the piston rod top of cylinder and the dead bolt of cover plate lower surface are fixed by steady pin; The cylinder side upper surface of described coal eye double-edged fine-toothed comb is provided with fixedly backplate.
Described track is provided with baffle plate away from an end of cylinder, and the length that the piston rod of cylinder stretches is more than or equal to the length of cover plate.
Described cylinder is fixed on the ground of trapped orbit side by side two.
The utility model beneficial effect is: the pneumatic envelope eye device of pulling-tray type of the present utility model is simple in structure, easy for installation; Cover plate carries out closure to the coal eye or unlatching has realized remote-controlled operation owing to the employing cylinder directly pushes away or spurs, and has saved manpower, also provides safety guarantee to operating personnel; Simultaneously cover plate is carried out push-pull fashion and also avoided process part of coal that the coal that transports on the belt and spoil fall into the coal eye or spoil to pound on the cover plate and cause the cover plate damage, prolonged the application life of cover plate.
Below in conjunction with accompanying drawing the pneumatic envelope eye device of pulling-tray type of the present utility model is described further.

Among the figure: 1, hoisting type cover plate, 2, lifting rope, 3, the hoisting type cylinder, 4, fixed pulley, 5, coal eye double-edged fine-toothed comb, 6, the piston rod of hoisting type cylinder, 7, cover plate, 8, cylinder, 9, pulley, 10, piston rod, 11, dead bolt, 12, track, 13, baffle plate, 14, fixing backplate.
The specific embodiment
As shown in Figure 1 and Figure 2, the hoisting type cover plate 1 that uses in the prior art is fixedly connected with hoisting type cylinder 3 by lifting rope 2, lifting rope 2 passes the fixed pulley 4 directly over the coal eye double-edged fine-toothed comb 5, rely on piston rod 6 flexible of hoisting type cylinder to decide rise or the landing of hoisting type cover plate 1 above coal eye double-edged fine-toothed comb 5, realize the sealing of 1 pair of coal eye of hoisting type cover plate or open.Hoisting type cover plate of the prior art falls behind for 1 time to exist needs the artificial hoisting type cover plate 1 that promotes the coal eye could be sealed; Be in the top of coal eye after hoisting type cover plate 1 is pulled up in addition always, the process that the coal that transports on conveyor when operation belt and spoil fall into the coal eye has the sub-fraction coal or spoil is pounded on the hoisting type cover plate 1, and the hoisting type cover plate 1 of being pounded by coal or spoil for a long time is damaged and lose the function of sealing coal eye easily.
As shown in Figure 3, Figure 4, the pneumatic envelope eye device of the pulling-tray type of present embodiment comprises coal eye double-edged fine-toothed comb 5, cover plate 7 and cylinder 8, the both sides of cover plate 7 as shown in Figure 5 are respectively arranged with two pulleys 9, are provided with the dead bolt 11 that is connected with piston rod 10 tops of cylinder 8 in the lower surface of cover plate 7; The coal eye both sides that coal eye double-edged fine-toothed comb 5 covers are provided with the track 12 corresponding with the pulley 9 of cover plate 7 both sides; Cylinder 8 is fixed with the ground of trapped orbit 12, and piston rod 10 tops of cylinder 8 and the dead bolt of cover plate 7 lower surfaces 11 are fixed by steady pin; The cylinder 8 side upper surfaces of coal eye double-edged fine-toothed comb 5 are provided with fixedly backplate 14.Track 12 is provided with baffle plate 13 away from an end of cylinder 8, and the length that the piston rod 10 of cylinder 8 stretches is more than or equal to the length of cover plate 7.Cylinder 8 is fixed on the ground of trapped orbit 12 side by side two.
The cover plate 7 that piston rod 10 promotions of cylinder 8 of the present utility model are connected with piston rod 10 tops, then the pulley 9 on the cover plate 7 slides until whole cover plate 7 covers the coal eye along track 12; The cover plate 7 that piston rod 10 pullings of cylinder 8 are connected with piston rod 10 tops, then the pulley 9 on the cover plate 7 slides until whole cover plate 7 leaves the coal eye along track 12, thereby realize that operating personnel are by the sealing of 7 pairs of coal eyes of cylinder 7 push-and-pull cover plates or the remote-controlled operation of unlatching, laborsaving and safety.
