Abstract
The utility model provides device of warning of buying securities with all one's capital under a kind of mine, including discharge roll and device of buying securities with all one's capital, the device of buying securities with all one's capital is set to below discharge roll, the device of buying securities with all one's capital includes by coal tong plate, travel switch and intermediate relay, it is described to be connected by coal tong plate with travel switch, the travel switch is connected with intermediate relay, and the intermediate relay is connected with voice call and driving motor emergency stop device, can warn in time coal bunker supervisor and can be automatically prevented from driving equipment operating.
Description
Technical field
The utility model relates to device of warning of buying securities with all one's capital under a kind of mine, overflow for the coal bunker of warning of one kind in mine raw coal transportation
Device for coal.
Background technique
In mine raw coal transportation transportational process, frequent occurrence since coal bunker supervisor supervision is not in place, raw coal is caused
Coal bunker is overflowed, gently then influences normal production, it is heavy then damage driving equipment.
Summary of the invention
The purpose of this utility model provides device of warning of buying securities with all one's capital under a kind of mine, and can warn coal bunker supervisor and energy in time
Enough it is automatically prevented from driving equipment operating.
In order to achieve the above object, the utility model includes discharge roll and device of buying securities with all one's capital, and the device of buying securities with all one's capital is set to
Below discharge roll, the device of buying securities with all one's capital include by coal tong plate, travel switch and intermediate relay, it is described by coal tong plate and stroke
Switch is connected, and the travel switch is connected with intermediate relay, and the intermediate relay is connected with voice call and driving
Motor emergency stop device.
Further, the travel switch is fixed on the travel switch fixed frame below the discharge roll.
Further, described by coal tong plate, travel switch is 2,2 travel switches with intermediate relay phase
Connection.
The utility model is compared with the existing technology: 1) when coal bunker overflow, it can effectively prevent continuing to run for driving equipment,
The labour for reducing worker is slight, reduces the Influence of production time；2) when coal bunker overflows, it is therefore prevented that raw coal buries head
The damage of unloading roller belt, speed reducer, coupler to caused by, motor are burnt, and the generation of Electromechanical Accidents is effectively reduced,
Guarantee property safety；3) two-way insurance can make voice and warn and cut off motor power, and manufacturing cost is low, easy to use
Simply.
Detailed description of the invention
Fig. 1 the utility model structure diagram；
Fig. 2 the utility model circuit control schematic diagram；
Appended drawing reference: 1, travel switch fixed frame, 2, by coal tong plate, 3, travel switch, 4, intermediate relay, 5, voice electricity
Words, 6, driving motor emergency stop device, 7, discharge roll, 8, belt, 9, coal bunker.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, device of warning of buying securities with all one's capital under a kind of mine, including discharge roll (7) and device of buying securities with all one's capital, the dress of buying securities with all one's capital
It installs and is placed in below discharge roll, the device of buying securities with all one's capital includes a pair of by coal tong plate (2), a pair of of travel switch (3) and one
Between relay (4), described to be connected by coal tong plate (2) with travel switch (3), the travel switch (3) and intermediate relay (4)
It is connected, the intermediate relay (4) is connected with voice call (5) and driving motor emergency stop device (6), the travel switch
(3) it is fixed on the travel switch fixed frame (1) below the discharge roll.
As shown in Fig. 2, the utility model control loop is to draw 127V power supply by illumination integrated protection, two are concatenated through Line 1
The normally closed point of travel switch is back to power supply, the control loop that row is closed at one by No. 2 lines after intermediate relay loop A 1, A2.
When coal bunker (9) is less than, travel switch is in normally open, and belt (8) machine runs well.When storehouse spill-over coal, coal position reaches stroke
When switch, since gravity is acted to one, travel switch, travel switch normally open contact closure promotes intermediate relay coil
It is powered, the normally open contact closure that intermediate relay is connected with voice call；Intermediate relay is connected with driving motor emergency stop device
Normally closed interlock open.
When storehouse spill-over coal, it is filled with coal by coal tong plate, since gravity is sunk by coal tong plate, gives travel switch
One movement, travel switch normally open contact closure, promotes intermediate relay coil to be powered, and intermediate relay is connected with voice call
Normally open contact closure, voice call power supply connect, start long sound；Intermediate relay is connected normal with driving motor emergency stop device
Contact opening is closed, main motor power supply disconnects, and motor shuts down.
