Description
Technical field
The utility model relates to coal coal mine belt conveyer, particularly a kind of coal coal mine belt conveyer permagnetic synchronous motor swelling device.
Background technology
The down-hole of China's coal-mine down-hole generally all adopts jinny tension or heavy-hammer tension with belt conveyer, seldom sees other type.Because jinny take-up device can only regular tightening belt, and the tensioning degree of belt is often relevant with the experience of operator, often occur that tensile force is excessive or too small, and directly have influence on the impact minor load of belt conveyer, thus jinny take-up device for the safety of conveyer and smooth running totally unfavorable.Weight hammer type tension is due to the restriction by pulley friction drag and weight force of inertia, and do not catch up with long distance, the response of high-speed belt conveyer, conveyor belt tension is obviously non-constant.In order to ensure the normal work of weight tensioning arrangement, underground coal mine will make a call to a large chamber.
Utility model content
The purpose of this utility model is to solve the problem, and devises a kind of coal coal mine belt conveyer permagnetic synchronous motor swelling device.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of coal coal mine belt conveyer permagnetic synchronous motor swelling device, comprise the travelling belt be sleeved on multiple roller bearing, also comprise tension drum, described travelling belt is sleeved on tension drum, described tension drum is provided with tension dolly, described tension dolly is provided with the driving control unit of its motion of traction, described driving control unit comprises tensioning magneto-electric machine, control frequency converter and the belt monitor in order to detect belt tightening, described control frequency converter is electrically connected with tensioning magneto-electric machine and grating sensor respectively, described control frequency converter and upper computer are electrically connected.
Described belt monitor is grating sensor.
Described grating sensor is positioned at directly over travelling belt.
Described tensioning magneto-electric machine is permagnetic synchronous motor.
The coal coal mine belt conveyer permagnetic synchronous motor swelling device utilizing the technical solution of the utility model to make, actv. overcomes the shortcoming of jinny and weight swelling device, automation can be realized according to the service condition adjustment belt tension degree of belt, but also can carry out being connected realizing remote operation with upper computer.

Fig. 1 is the structural representation of coal coal mine belt conveyer permagnetic synchronous motor swelling device described in the utility model;
In figure, 1, travelling belt; 2, tension drum; 3, dolly is strained; 4, tensioning magneto-electric machine; 5, frequency converter is controlled; 6, upper computer; 7, belt monitor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described, as shown in Figure 1, a kind of coal coal mine belt conveyer permagnetic synchronous motor swelling device, comprise the travelling belt (1) be sleeved on multiple roller bearing, also comprise tension drum (2), described travelling belt (1) is sleeved on tension drum (2), described tension drum (2) is provided with tension dolly (3), described tension dolly is provided with the driving control unit of its motion of traction, described driving control unit comprises tensioning magneto-electric machine (4), control frequency converter (5) and the belt monitor (7) in order to detect belt tightening, described control frequency converter (5) is electrically connected with tensioning magneto-electric machine (4) and grating sensor respectively, described control frequency converter (5) and upper computer (6) are electrically connected, described belt monitor (7) is grating sensor, described grating sensor is positioned at directly over travelling belt (1), described tensioning magneto-electric machine (4) is permagnetic synchronous motor.
The feature of the present embodiment is, travelling belt is sleeved on tension drum, tension drum is provided with tension dolly, tension dolly is provided with the driving control unit of its motion of traction, driving control unit comprises tensioning magneto-electric machine, control frequency converter and the belt monitor in order to detect belt tightening, control frequency converter to be electrically connected with tensioning magneto-electric machine and grating sensor respectively, control frequency converter and upper computer are electrically connected, actv. overcomes the shortcoming of jinny and weight swelling device, automation can be realized according to the service condition adjustment belt tension degree of belt, but also can carry out being connected realizing remote operation with upper computer.
In the present embodiment, the situation of bearing load before use according to belt sets the Driving Torque of an initial value as motor to controlling frequency converter, when adopting process for stoping to mine, along with the propelling backward in back production district, the usable length of travelling belt is shorter and shorter, the tensioner degree of belt is more and more less, pulling force between tensioner magneto-electric machine and tensioner dolly is reduced, machine torque on tensioner motor shaft is less than the Driving Torque of motor setting, electric machine rotation, the pulling force between tensioner magneto-electric machine and tensioner dolly is made to become large gradually, the motor stalls when the machine torque on tensioner motor shaft equals the Driving Torque of motor setting, control frequency converter to be also connected with upper computer or belt monitoring device composition closed loop, result before and after belt tension contrasts on belt detecting device, the automatic adjustment setting value controlled in frequency converter realizes the automatic control of swelling device, or immediately change by upper computer the Long-distance Control that the setting value controlled in frequency converter realizes swelling device, finally all moment balance can be reached, make motor stalls, tensioner terminates.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
