The weighing sensor is mounted on the lower portion of the measure hopper, and the tongue depressor controller is mounted at the lower end of a tongue depressor and is connected to the master control system through the control signal line. The emptying judgment of the skip bucket provided by the invention adopts a direct mode of detecting a running current rather than judgment by virtue of an indirection method of monitoring opening and closing of a skip bucket door, and the loading and unloading control equipment is safe and convenient, energy-saving, environmental-friendly, fast in loading reaction speed and energy-saving.
Description
Technical field
The invention belongs to mine hoist manufacturing technology field, and in particular to a kind of loading and unloading control device.
Background technology
Elevator is the crucial production equipment for undertaking mine personnel and material lifting task, is the throat that mine well is contacted up and down, is one of technology content highest equipment in mine, is also the guarantee for realizing shaft production and benefit goal.
The key equipment that mine hoist produces coal as mine, the state of its operation is directly connected to the economic benefit of mine.In the mine hoist system of vertical, coal is carried using skip bucket.And typically all two skip bucket circularly enhancings, the useful load of each skip bucket has certain surplus coefficiert.Mine hoist runs into unavoidably the skip bucket refitting overload problem caused because skip bucket is not unstowed, or maintenance or disastershutdown after the loading is performed during coal is carried, and has carried out the skip bucket refitting overload problem for once loading and causing when driving next time again.If the refitting overload of skip bucket has exceeded the hoisting power of winch again, once there are Similar Problems, difficulty is dealt with larger, need manually to lay down, often to spend time of 2-3 classes to process, thus delay the production time significantly, be unfavorable for the safety in production at scene.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, it is proposed that a kind of loading and unloading control device, its invention objective is：Judged skip bucket either with or without unstowing according to the motor current of motor during the loading and unloading of mine hoist.The anti-refitting of system is realized by the loading and dumping system invented.
In order to solve the problems, such as prior art, the present invention is employed the following technical solutions：
The present invention includes coal bunker, feeder, master control system, measure hopper, belt feeder and skip bucket, it is characterized in that：The master control system is connected respectively by control signal wire with skip bucket, measure hopper, feeder and belt feeder, the skip bucket judges skip bucket either with or without unstowing according to motor current, and current information is passed to master control system by control signal wire, the measure hopper includes LOAD CELLS and spatula controller.
The LOAD CELLS is arranged on the bottom of measure hopper, and the spatula controller is arranged on the lower end of spatula, is connected with host computer system by control signal wire.
The control signal wire is controlled using RS485 mode bus.
The host computer system includes manual, semi-automatic and automatic three kinds of control models.
The present invention has the advantages that following four aspect compared with traditional control system：
1st, space-time is not unloaded when there is skip bucket, then system can send sound and light alarm signal, and master control system switchs to manual mode automatically, it is ensured that production safety；
2nd, skip bucket is unstowed and judges the direct mode for adopting detection running current, is judged with the indirect method of monitoring skip bucket door folding；
3rd, measure hopper directly feeds back useful load using sensor to master control system, and master control system real-time control feeder start and stop load reaction speed fast；
4th, the service life of system, and energy saving can to greatest extent be extended.

Specific embodiment
Refering to shown in Fig. 1; the present invention includes coal bunker 1, feeder 2, master control system 7, measure hopper 8, belt feeder 3 and skip bucket 9; coal is coaling by the feeder 2 of 1 time mouth of coal bunker; measure hopper 8 is transported into by belt feeder 3; when Jing pressure magnetic cell meterings reach rated value; stopping signal is sent to master control system 7 by control signal wire 10; master control system 7 sends instruction of stopping transport by control signal wire 10 to belt feeder 3, feeder 2 and spatula controller 5; after belt feeder 3 stops; spatula 6 is retracted, and skip bucket 9 is lifted.Master control system 7 includes data signal input/output port, analog signal input/output port and On-off signal delivery outlet, realize dynamic auto being loaded control, the control signal wire 10 is realized sequential control, and is monitored in operating desk using RS485 mode bus to feeder 2, belt feeder 3, spatula 6.Master control system 7 have it is manual, semi-automatic and automatically control three kinds of forms, when manual, can unit operation, it can also be used to overhaul；When semi-automatic, unloading automatically, after completion of discharge, sends manually starting signal after waiting skip bucket 9 in place, skip bucket 9 is lifted, now, the loading process of belt feeder 3 is automatic, i.e., belt feeder 3 starts at a slow speed feeder 2 after time delay two seconds and starts, after the fully loaded display of the metering of LOAD CELLS 4, stop feeder 2 by host computer system 7, belt feeder time delay stops after four seconds, wait skip bucket 9 to reprint in place；If automatically, as the completion of discharge of skip bucket 9 shows the state of the detection feeder 2 of master control system 7 and belt feeder 3 after zero load, starting signal is sent when normal automatically, without the control of personnel's participation process.
Refering to shown in Fig. 2, the master control system 7 is connected and exchange data by control signal wire 10 and two measure hoppers 8 of spatula controller 5, two of LOAD CELLS 4, two of belt feeder 3, two of feeder 2, two with two skip buckets 9, measure hopper 8 includes LOAD CELLS 4 and spatula controller 5, master control system 7 directly controls spatula 6 directly by the gathered data of LOAD CELLS 4 by spatula controller 5.
The skip bucket 9 judges skip bucket 9 according to motor current either with or without unstowing, and current information is passed to master control system 7 by control signal wire 10, and its principle is：
Calculate the normal hoisting electric current IxT of skip bucket 9, T for loading coal tonnage, I is to lift the electric current required for coal per ton, and the result after calculating and skip bucket 9 are not unloaded the electric current I (reality) of space-time to be compared, once and its difference（I（It is actual）- IxT）More than a certain boundary line, that is, think that skip bucket 9 is not unstowed.
Actual current when can not reflect lifting strictly according to the facts due to electric current of the skip bucket 9 in acceleration or deceleration, therefore the controller of skip bucket 9 to electric current when being monitored, and selectes a certain raising section in the middle of when skip bucket 9 is at the uniform velocity lifted to calculate the time period.Once skip bucket 9 occur does not unload space-time, master control system 7 sends sound and light alarm signal, system switchs to manual mode, not allowing for reaching the skip bucket 9 of " loaded " position carries out coaling operation, now, under manual mode, the skip bucket 9 do not unstowed is mentioned into unloading position again, skip bucket 9 is unstowed, and Jing after manually button confirms, system recovers normal operation.
Skip bucket belonging to the present invention is unstowed and judges the direct mode for adopting detection running current, is judged with the indirect method of monitoring skip bucket door folding, and safe ready, energy-saving and environmental protection load reaction speed soon, energy saving.
