Description
Technical field
The utility model belongs to Strap Transporter in Coal Mine systems technology field, especially relates to a kind of mining tensioning motor control assembly.
Background technology
Tensioning motor control assembly is the indispensable important component part of underground mine use belt conveyor system, is the key ensureing that belt normally starts, runs, brakes and stops.Along with the extension of coal mine roadway and the requirement of transport capacity, the application of long distance high-power belt transport plane has had higher requirement to tensioning electric machine control system, when belt tension is excessive, and excessive belt stretch, stress fatigue strengthens, and easily occurs that fault broken by belt; When belt tension is not enough, cause slipping of the belt and broken belt, fired fault, but also easily there is the series of problems such as belt lateral vibration is excessive, consumption of power is excessive, the devices such as weight hammer type, fixed type, hydraulic oil cylinder type can not meet the performance that tension force regulates in real time.
At present, the tensioning motor control assembly that underground coal mine uses exists that speed of response is slow, stroke of tension is short, can not the defect such as tension adjusting in real time, causes the phenomenons such as slipping of the belt, fracture, coal accumulation.Therefore, this just need to provide a kind of can meet belt transporter tensile force carried out in real time, control efficiently, the tensioning motor control assembly with complete protective effect little to belt impulsive force.
Summary of the invention
In view of this, the utility model is intended to propose a kind of mining tensioning motor control assembly, controls tensioning motor, and then controls the size of tensile force, when satisfied startup, braking, tension force will meet dynamic skid-resistance requirements, and constant velocity stage meets the requirement that belt transporter normally runs.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of mining tensioning motor control assembly, comprises interconnective four-quadrant frequency converter and master controller, connected system sensor, Long-distance Control case and wireless controller on described master controller; Described four-quadrant frequency converter connects power input.
Further, described system sensor comprises tension pick-up, misalignment sensor, heap coal sensor, Smoke Sensor, speed sensor, Temperature Humidity Sensor and vertical tears sensor.
Relative to prior art, the utility model has following advantage:
(1) there is excellent dynamic response ability, within the extremely short time, respond the change of belt conveyer belt tension force; Particularity and good response characteristic are considerably beyond the tightening device of hydraulic pressure or dynamo-electric form;
(2) be only that it just starts drive motor when needed, after the scope that tension adjustment to applicable conveyer belt normally runs, tensioning motor will cut out gradually, therefore, and the tenslator that this is mining tensioning motor control assembly is a kind of volume is little, efficient, energy-conservation.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of mining tensioning motor control assembly of the utility model, as shown in Figure 2, comprises interconnective four-quadrant frequency converter 2 and master controller 3, connected system sensor 5, Long-distance Control case 7 and wireless controller 8 on described master controller 3; Described four-quadrant frequency converter 2 connects power input 4 and tensioning motor 6.
Described system sensor 5 comprises tension pick-up, misalignment sensor, heap coal sensor, Smoke Sensor, speed sensor, Temperature Humidity Sensor and vertical tears sensor; All be arranged on the relevant position of the conveyor structure of mining clamping system.
Described tensioning motor control assembly 1 is applied to conveyer for mine clamping system, and as shown in Figure 1, system is made up of the conveyer belt connected successively, sliding machine, capstan winch, tensioning motor and tensioning motor control assembly 1.Described system sensor 5 returns the detected value of conveyer belt to master controller 3, master controller 3 can detect four-quadrant frequency converter 2 signal, system sensor 5 signal, remote control signal and wireless control signal etc. in real time, control signal is exported by computing, drive tensioning motor 6, and realize corresponding defencive function, there is visible human circle operation display interface simultaneously; The detected value that master controller 3 returns according to the various sensors of system sensor 5, the motor output speeds of change tensioning in real time, controls Tensity size; Can manually, automatically carry out arranging system parameter, control system running state etc.; Long-distance Control case 7 communicates with master controller 3, realizes the mining clamping system of Long-distance Control and runs; Wireless controller 8 is communicated with master controller 3 by wireless signal, can not realize real time inspection system running state, arrange system parameter, control system run action etc. by the impact of personnel positions
The utility model adopts four-quadrant frequency converter 2 to control tensioning motor 6 as driver output, belongs to repeatedly continuous duty in short-term, and the deceleration range of decrease is comparatively large, and braking time is shorter; Realize the two-way flow of energy, according to the size of tension value, stepless change adjustment tensioning motor 6 rotating speed can be realized, accomplish to control adjustment rotating speed by tension requirements value, ensure that system stability, in addition, positive and negative rotating speed controllable characteristics can realize the speeds control of belt taut band, pine band; The energy that tensioning motor 6 feedback can also be produced is counter delivers to electrical network, reaches energy-conservation effect; Described power input, for colliery downhole equipment provides the three phasevoltage 3300V/1140V/660V etc. of use.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
