Abstract
The utility model relates to a temperature monitoring system of scraper conveyor gearbox for coal mine machinery, including a temperature sensor, a data acquisition card, a computer and a control unit, the temperature sensor is arranged inside the scraper conveyor gearbox, an output terminal of the temperature sensor followed by the data acquisition card and the computer is connected with an input terminal of the control unit, an outpur terminal of the control unit is connected to a working input terminal of an oil cycling motor and a spray cooling system of the scraper conveyor gearbox at the same time. In practical work, a electric signal is output from the temperature sensor of gearbox and then input into the computer through the data acquisition card, a temperature signal is compared with an input-ahead temperature threshold by controlling a computer software, when the temperature signal is higher than the temperature threshold, the oil cycling motor is started by the control unit, the oil in the gearbox is pumped out by a driving pump, while the spray cooling system also is started by the control unit, the object of the invention is to cool the gearbox.
Description
Technical field
The utility model belongs to coal mine machinery equipment protection system technical field, relates to a kind of scraper conveyor reducer casing temperature monitoring system.
Background technology
The function of scraper conveyor for coal mines is the raw coal of transportation coalcutter exploitation.Known scraper conveyor is due to reasons such as transportation range are far away, raw coal freight volume is large, installed power is large and continuous operation time is long, during the reduction gear of scraper conveyor (reducer casing) continuous operation, easily there is superheating phenomenon, thereby cause the scraper conveyor cannot reliably working.Although this area is also provided with the spray cooling system (referring to Fig. 1) for lowering the temperature at present on the reduction gear of some scraper conveyors, its supporting supervisory system also has certain defect, is still difficult to the request for utilization that reaches satisfied.
Utility model content
The purpose of this utility model is that the problem that prior art is existed solves, and a kind of rational in infrastructure, easy to operate, the scraper conveyor reducer casing temperature monitoring system that can monitor in real time scraper conveyor reducer casing working temperature is provided.
The technical solution adopting is for achieving the above object such: the scraper conveyor reducer casing temperature monitoring system providing is comprised of temperature sensor, data collecting card, computing machine and control module, temperature sensor is arranged in the reducer casing of scraper conveyor, its output terminal connects with the input end of control module successively after data collecting card and computing machine, and the output terminal of control module is connected to the oil circulation motor of scraper conveyor reducer casing and the work input end of spray cooling system simultaneously.In real work, from temperature sensor output electrical signals in reducer casing, through data collecting card input computing machine, by computer software control and the temperature threshold pre-entering, contrasted.When the temperature signal from temperature sensor is during higher than temperature threshold, by control module, start oil circulation motor, driving pump is extracted the fluid in reducer casing out through coiled pipe, control module also starts the spray cooling system of reducer casing simultaneously, coiled pipe spray cold water by from this system to transmission high-temperature oil liquid, thereby cooling oil.Through cooling fluid, input again reducer casing, reach the object that makes reducer casing cooling; When temperature is within threshold value, stop oil pumping, spray cooling system also stops spray.
Accompanying drawing explanation
Fig. 1 is the structural representation of a specific embodiment of the utility model.
In figure, the title of each number designation respectively: 1-temperature sensor, 2-data collecting card, 3-computing machine, 4-control module, 5-oil circulation motor, 6-pump, 7-spray cooling system, 8-reducer casing, 9-coiled pipe.
Embodiment
As shown in the figure, scraper conveyor reducer casing temperature monitoring system described in the utility model is comprised of temperature sensor 1, data collecting card 2, computing machine 3 and control module 4, the output terminal of temperature sensor 1 connects the input end of control module 4 successively after data collecting card 2 and computing machine 3, and the output terminal of control module 4 is connected to the oil circulation motor 5 of scraper conveyor reducer casing and the work input end of spray cooling system 7 simultaneously.
In concrete enforcement, temperature sensor 1 is placed in reducer casing 8, monitors in real time the temperature of reducer casing 8 inner fluids.The output electrical signals of temperature sensor 1, through data collecting card (carrying AD modular converter) 2 input computing machines 3, is contrasted by computer software control and the temperature threshold pre-entering.When the temperature signal from temperature sensor 1 is during higher than temperature threshold, by control module 4, start oil circulation motor 5 driving pumps 6 fluid in reducer casing 8 is extracted out through coiled pipe 9; In control module actuating motor, also start spray cooling system 7, this system can spray cold water to the coiled pipe 9 of transmission high-temperature oil liquid, thereby cooling oil is inputted again reducer casing through cooling fluid.When temperature is within threshold value, stop oil pumping, spray cooling system also stops spray.
