The coal level alarm device has the advantages of simple system composition and structure, low cost, sensitive action and high operational reliability, can effectively avoid phenomena such as empty bunker and over high coal level, protects the coal bunker and the coal feeder, and avoids bunker blockage and channeling.
Description
Technical field
The present invention relates to the coal mine equipment technical field, relate in particular to a kind of coal bin coal position warning device.
Background technology
In mine raw coal transportation, in the raw coal often with bulk spoil and a large amount of moisture content.When the coal position is too high in the coal bunker of feeder, coal bunker can occur and stop up, scurry accidents such as storehouse, damage equipment, influence mine normal production, even threat underground work personnel's personal safety; When coal bunker is hole capital after selling all securities, raw coal---particularly be mingled with the raw coal of bulk spoil, directly fall the bottom, easily feeder is caused serious damage from the coal bunker entrance of tens meters or higher position.
For addressing the above problem, and occurred based on the ultrasonic coal position detector system of sound wave with based on the vision coal position detector system of laser, though above-mentioned two kinds of coal position detector systems can be surveyed the coal position in the coal bunker.But, because ultrasonic coal position detector system and vision coal position detector system all belong to precision instrument, under the abominable working environment of this high humidity of mine, high dust, are difficult in their survey precision and service life guarantee, cause problems such as reporting by mistake or do not report easily.In addition, adopt ultrasonic coal position detector system and vision coal position detector system that the coal position is surveyed, the entire system more complicated, cost is high.
Summary of the invention
The present invention provides a kind of simple in structure, cost is low, reliability of service is high coal bin coal position warning device.
The present invention provides a kind of coal bin coal position warning device, comprises control unit, alarm unit and mechanical performance element; Said control unit comprises series connected Switching Power Supply, relay coil and travel switch; Said alarm unit comprises series connected relay normally open contact and alert lamp; Said mechanical performance element triggers control with travel switch and cooperates and be used to be installed in the feeder deflector chute.
Aforesaid coal bin coal position warning device; Wherein, Said mechanical performance element comprises rotor plate; Said rotor plate is used to be arranged in the said feeder deflector chute and is hinged on the sidewall of said feeder deflector chute, also is hinged with connecting rod on the said rotor plate, and said connecting rod is used to pass said feeder deflector chute away from an end of said rotor plate and the triggering handle of outer said travel switch flexibly connects with being arranged on said feeder deflector chute.
Aforesaid coal bin coal position warning device, wherein, said rotor plate is used to be hinged on said feeder deflector chute, along on the sidewall of outward-dipping expansion from top to bottom.
Aforesaid coal bin coal position warning device, wherein, the articulated position of said rotor plate and said feeder deflector chute is higher than the articulated position of said rotor plate and said connecting rod.
Aforesaid coal bin coal position warning device, wherein, said rotor plate and said feeder deflector chute pivotally attached axis are horizontal.
Aforesaid coal bin coal position warning device, wherein, said alert lamp is used to be installed on sealing-tape machine head control cabin.
Coal bin coal position warning device provided by the invention system form and simple in structure, cost is low, be active in one's movements, functional reliability is high, can effectively avoid hole capital after selling all securities, coal position to cross high phenomenon.Protected coal bunker and feeder, avoided stifled storehouse, scurry storehouse accident generation.

The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
As shown in Figure 1, the embodiment of coal bin coal position warning device of the present invention comprises control unit 2, alarm unit 1 and mechanical performance element 3.Machinery performance element 3 accordingly control unit 2 implements control according to the height of coal position 5.Control unit 2 moves according to mechanical performance element 3 control corresponding, comes alarm unit 1 is opened, stops operation.
Fig. 3 is the electrical schematic diagram of above-mentioned coal bin coal position warning device embodiment, below in conjunction with this electrical schematic diagram the working process and the principle of coal bin coal position warning device is introduced.Coal position 5 in feeder deflector chute 9 is lower, and be lower than rotor plate 6 bottom the time, as shown in Figure 1; Rotor plate 6 is near sagging position, and at this moment, travel switch K is in closure state; When the stroke K switch is closed; 24V Switching Power Supply DC gives relay coil KM power supply, and relay coil KM gets electric back and produces induced field, through this induced field with relay normally open contact KM
1Adhesive, the bright L of alert lamp this moment explains that the coal position 5 in the feeder deflector chute 9 is lower, need stop feeder.Coal position 5 in feeder deflector chute 9 is higher, and when being higher than rotor plate, as shown in Figure 2; Because the accumulation of raw coal when falling promotes rotor plate 6 and rotates to a side who is affixed to sidewall 10, and progressively increasing along with coal position 5; Rotor plate 6 finally is attached on the sidewall 10, and in sidewall 10 rotating process, rotor plate 6 drive link 4 are to left movement at rotor plate 6; Connecting rod 4 promotes to trigger handle 7 again to left movement, and when rotor plate 6 touched sidewall 10, travel switch K had been in off-state.At this moment, relay coil KM power down, relay normally open contact KM
1Keep off-state, alert lamp L goes out, and explains that coal position 5 is higher, needs to start feeder and carries out the raw coal conveying.
What should explain at last is: above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although with reference to previous embodiment the present invention has been carried out detailed explanation, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of the essence disengaging various embodiments of the present invention technical scheme of relevant art scheme.
