Description
Technical field
The utility model belongs to mechanical equipment automatic control technology field, especially belongs to a kind of mining equiment automatic control skill
Art field, the in particular to device of a kind of the motor balanced adjustment and belt slippage alarm broken for bi-motor counterattack.
Background technique
Impact breaker be it is a kind of using impact energy come the crushing mechanism of broken material.When machine operation, in motor
Drive under, rotor high speed rotation, when material enters bar active region, hit with the bar on rotor it is broken, it is rear to be thrown to again
It is crushed again on counterattack device, then bounces back into bar active region from beating lining plate and be crushed again, this process repeats, material
It is descending to repeat to be crushed into one, two, three back cavities, until material is crushed to required granularity, it is discharged by discharge port.
Since the rotor of impact breaker is than heavier, and bar is installed above, there is foot when in order to guarantee rotation
Enough kinetic energy and stationarity, general to strike back broken shaft two sides meeting there are two same belt pulley, bi-motor passes through from two sides respectively
Belt connects belt pulley and drives rotor rotation.If two motor imbalances, it will cause the big loss of electric machine of electric current and increase, simultaneously
Can not efficient operation, motor can be directly damaged when serious.
There are two the factors for the balance that will affect bi-motor in the broken operational process of counterattack, first is that the revolving speed of motor, two
It is the elasticity of belt.Counterattack can generally select the same motor of same batch when breaking factory, make each of motor as far as possible
Parameter such as revolutional slip etc. is close, keeps the revolving speed of motor identical.In the suitable situation of selection of Motor, influence to strike back brokenly two-side motor
Unbalanced main cause becomes the elasticity of belt.
Two sides belt tightening can be made as far as possible identical when installation although counterattack is broken, it is contemplated that the installation of belt
And replacement, permanent positioning can not be realized to motor, while striking back broken is heavy-duty machinery, can generate very big vibration in use process
Dynamic, the fixation means of motor will loosen, to affect the balance of bi-motor, ultimately cause efficiency be lower, belt slippage very
To consequences such as motor damages.
Existing bi-motor counterattack is broken to be usually required manually periodically to carry out tightening operation to belt, the micro- skidding of belt is occurring
Shi Wufa is monitored in time, and for example bored machine of emergency etc. can not provide stopping signal in time.
Summary of the invention
The utility model is disclosed according to prior art deficiency and a kind of is alarmed for motor balanced adjustment and belt slippage
Device.Problem to be solved in the utility model be to provide it is a kind of the rate of tension of belt can be adjusted in real time, and can be with
Belt speed is detected, provides operating status in time for motor balanced adjustment and the device of belt slippage alarm.
The utility model is achieved through the following technical solutions:
For the device that motor balanced adjustment and belt slippage are alarmed, the belt pulley including driving spindle rotation, the skin
Belt wheel is driven simultaneously by two groups of belts, it is characterised in that: further includes hunting gear, current detection means and central processing unit；
Be respectively set hunting gear in two groups of belt surfaces, hunting gear include: setting and belt surface supporting roller,
It supports and drives the speed measuring coder and pressure sensor installed on the hydraulic cylinder and supporting roller of supporting roller；
Current detection means includes the Current Mutual Inductance on two groups of two electric motor loops for being separately mounted to two groups of belt pulleys of driving
Device and its current transducer composition；
Central processing unit connect with speed measuring coder, pressure sensor, current transducer data-signal and with it is each hydraulic
Oil cylinder and warning device electrical connection.
Two groups of belts of driving belt pulley are arranged in parallel simultaneously, identical with each argument structure of belt including driving motor.
Central processing unit uses PLC, single-chip microcontroller or industrial personal computer, acquires two speed measuring coders, two pressure sensings
The data-signal of device and two current transducers is simultaneously compared.
Central processing unit compares two electric currents and obtains electricity by the electric current of input two motors of acquisition of current transducer
The equilibrium state of machine, while being used to do motor booting instruction.
Central processing unit is recorded and is compared by speed measuring coder acquisition belt speed.Pass through the normal condition with storage
Revolving speed and the real-time revolving speed on both sides compare belt slippage phenomenon whether occurred.
Central processing unit drives the hydraulic oil on both sides by the analysis result of the revolving speed of electric current and belt feeder to motor
Cylinder ascending, descending, in the case where not having skidded, the hydraulic cylinder of the small side of driving current increases pressure, the big side of electric current
Hydraulic cylinder reduce pressure.
Central processing unit real-time monitoring slipping state drives hydraulic cylinder to increase corresponding skid if there is skidding
The tensioning pressure of side belt, and alarm threshold value analysis is carried out to slipping state, if it is micro- skidding or only side skidding, then
The tensioning pressure for only alarming and increasing skidding side belt alarms if two sides are skidded simultaneously and provides stopping signal, after convenient
Continuous system intervention.
The utility model is increasing belt pulley and guaranteeing the rate of tension of belt in such a way that belt pulley presses tensioning
And belt speed can be detected by belt pulley simultaneously.In this way, can solve the artificial frequently adjustment belt of needs
The problems such as tightness, micro- skidding can not detect and bored machine can not provide alarm signal in time.
Utility model device can monitor and obtain belt slippage state and automatically process and alarm, automatic to monitor belt
Clamp force simultaneously adjusts, and can monitor small slipping state, is judged in advance broken operating status is struck back, bi-motor can be made in a certain range
Inside always in maximum equilibrium state.
