Abstract
The utility model discloses a liftable rock flying-preventive device at a lower outlet of a large-inclination fully-mechanized working surface, which comprises a lower coal-blocking plate that is arranged at the tail of a transporter by a bolt, two hydraulic cylinders are vertically arranged at the back of the lower coal-blocking plate at interval, the upper ends of piston rods of the two hydraulic cylinders are connected with an upper coal-blocking plate, the upper coal-blocking plate is the same wide as the lower coal-blocking plate, and the lower plate surface of the upper coal-blocking plate is superposed with the upper plate surface of the lower coal-blocking plate. The liftable rock flying-preventive device at the lower outlet of the large-inclination fully-mechanized working surface is simple in structure, can effectively prevent the phenomenon that the flying rock hurts people during large-inclination coal mining operation, and ensures the safety production of a coal mine.
Description
Technical field
The utility model relates to the Liftable type anti-cash device that flies in exit under the retaining cash device, particularly large tilt angle compound mining work plane that a kind of Safety of Coal Mine Production uses.
Background technology
ForThe coal seam is the colliery of half-edge coal seam, because geological conditions is comparatively complicated, seam inclination is bigger, mean obliquity is 43 °, cause wall caving serious during working surface production, fly the cash especially severe, because the work plane inclination angle is big, fly (coal) cash, the wall caving situation is serious, the coal that lumpiness is bigger (cash) piece quality is often at 100 ~ 200kg, most of coals (cash) piece quality is in 20 ~ 50kg scope, because the inclination angle is bigger, the work plane tilt length is grown (120m), and the whereabouts acceleration of coal (cash) piece is very big, coal (cash) tumbles to the lower end spillplate from work plane, cause coal (cash) very big to lower end pedestrian exit impact force, general employing hangs flexible metal net and keeps off cash, and the operating position of artificial moving metal net.But at the bottom of finding wire lath well damage, troublesome poeration, intensity aborning, poor stability.The personnel injury accident of causing is comparatively frequent, personnel is passed through also bring great potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide under a kind of large tilt angle compound mining work plane that the exit Liftable type is anti-to fly the cash device, and is not only simple in structure, and can change the operating position in maneuverability ground, can effectively improve and prevent flying the cash effect, guarantees the safety in production in colliery.
The purpose of this utility model is to realize like this, the Liftable type anti-cash device that flies in exit under a kind of large tilt angle compound mining work plane, this device comprises a following spillplate that is installed in the reprinting tail by bolt, at vertical interval, the back side of following spillplate two hydraulic cylinders are being set, the piston rod upper end of two hydraulic cylinders links together with a last spillplate, the width of last spillplate is identical with the width of following spillplate, the upper board face overlaid of the lower panel face of last spillplate and following spillplate.
The utility model is realized going up the automatic lifting of spillplate and moving by hydraulic cylinder, has changed the situation that in the past adopts Chain Link Fence retaining cash, has improved the anti-reliability that flies cash work of Coal Production greatly.When protection is highly higher, can use two block plate pin formulas to connect and increase the protection height, this device is installed on the elevating conveyor, by elevating conveyor from moving, it is simple to operate, help to reduce worker's manual labor, labour intensity lowers greatly, has reduced the danger of handling when outlet flies the cash problem down simultaneously.This apparatus structure is simple, and what occur in the time of can preventing the high inclination-angle coal mining activity effectively flies the cash phenomenon of hurting sb.'s feelings, and guarantees Safety of Coal Mine Production.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
The Liftable type anti-cash device that flies in exit under a kind of large tilt angle compound mining work plane, as shown in Figure 1, this device comprises a following spillplate 1 that is installed in the reprinting tail by bolt, at vertical interval, the back side of following spillplate 1 two hydraulic cylinders 2 are being set, the piston rod upper end of two hydraulic cylinders 2 links together with a last spillplate 3, the width of last spillplate 3 is identical with the width of following spillplate 1, the upper board face overlaid of the lower panel face of last spillplate 3 and following spillplate 1.
Can use two block plate pin formulas to connect and compose spillplate 3, two block plates when protection is highly higher can horizontal arrangement also can vertically be arranged side by side, so that increase the protection height.
The utility model is simple in structure, is installed in the elevating conveyor afterbody, need not artificial mobile working position, and what occur in the time of can preventing the high inclination-angle coal mining activity effectively flies the cash phenomenon of hurting sb.'s feelings, and guarantees Safety of Coal Mine Production.
