Description
Technical field
The utility model relates to a kind of belt tear-preventing warning effectively solving belt tearing problem when belt-conveying operation, is applied to the belt-conveying fields such as mine, industrial and mining enterprises, building engineering.
Background technology
Belt-conveying is the important component part of mine ores lifting system.In the Belt Conveying ore process of mine, being easy to belt to scratch when being accidentally mixed into ironware in ore, causing belt tearing, occur the phenomenon of leaking ore deposit.If find not in time, can cause belt breach continuous enlargement, cause whole belt conveyor system to be paralysed time serious, again must change belt, this can have a strong impact on normal production.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of belt tear-preventing warning effectively solving belt tearing problem when belt-conveying operation.
Above-mentioned purpose is realized by following proposal:
A kind of belt tear-preventing warning, it is characterized in that, described warning comprises magnet proximity switch (1), is arranged on the movable iron sheet baffle plate (2) in this magnet proximity switch detection range; Described magnet proximity switch open contact and relay K M1(3) coils connected in series form loop; Described relay K M1(3) normally closed contact (4) and relay K M2(5) coils connected in series and electric bell alarming reset switch (6) connect and form loop; Described relay K M2(5) open contact (7) connect with warning electric bell (8) and form loop; Described relay K M2(5) normally closed contact (9) connect with belt control loop; Described relay K M2(5) open contact (11) and relay K M1(3) open contact (4) in parallel.
The beneficial effects of the utility model: the utility model can not only realize effectively solving belt tear-preventing warning problem in the Belt Conveying ore process of mine, and in use safe and reliable, simple to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See Fig. 1, belt tear-preventing warning system of the present utility model comprises magnet proximity switch 1, is arranged on the movable iron sheet baffle plate 2 in magnet proximity switch 1 detection range.Magnet proximity switch open contact and relay K M1(3) coils connected in series form loop; relay K M1(3) normally closed contact 4 and relay K M2(5) coils connected in series and electric bell alarming reset switch 6 connect and form loop; and by relay K M2(5) open contact 11 and relay K M1(3) open contact 4 in parallelly form self-keeping circuit, maintenance KM2(5) coil be in attracting state always.Relay K M2(5) open contact 7 connect with warning electric bell 8 and form loop.Relay K M2(5) normally closed contact 9 connect with belt control loop 10.
The principle of work of system is: movable iron sheet baffle plate 2 is arranged on lower floor's belt and is about 1m place apart from rock feeder feed opening rear, under normal circumstances, distance between ferromagnetic proximity switch 1 and movable iron sheet baffle plate 2 is 30mm, shifting board is in the detection range of switch, now, the open contact of ferromagnetic proximity switch 2 inside is in attracting state; After belt tearing occurs leaking ore deposit, the ore leaked can clash into shifting board along with the operation of lower floor's belt, thus make movable iron sheet baffle plate 2 exceed the detection range of ferromagnetic proximity switch 1, and then the open contact of ferromagnetic proximity switch 1 inside is disconnected, now with the ferromagnetic close relay K M1 dead electricity opened 1 pass open contact and connect, the normally closed contact adhesive of relay K M1, relay K M2 is obtained electric, thus make the open contact adhesive of relay K M2, electric bell loop is obtained electric, cause electric bell alarming; The relay K M2 normally closed contact of simultaneously connecting with belt operational system disconnects, and makes belt system out of service.Protect power failure road because native system design has employed, need hand reset when removing warning, when pressing the electric bell alarming reset button SB on control housing when operating personal, system reset, after resetting, belt conveyor system can restart.
Claims (1)
