Protective value is carried, is a kind of mechanical soft start equipment.Found in actual production process, the activity duration is long, stream is big, load again etc.
Reason, it can all make the rise of coupling device temperature, internal oil pressure increase, cause the fusible alloy piece of coupling device fusible plug to act, be coupled
Working oil in device sprays, and causes the transmission of power to be cut off rapidly, reductor, belt shut down in succession.But now PLC is still
Can make to remain in operation as the motor of prime mover because belt feeder system electrically do not have performance be out of order, prime skin
Still normal band is burnt for band machine, chute is piled with coke and overflows, is scattered, the prime belt of operation and the coke mill of bulk deposition
Wipe, cause the abrasion on belt top layer, scratch, or even trigger belt cracking to draw saturating substantial equipment accident.Therefore it is how effectively anti-
The only further sprawling of fluid-flywheel clutch failure, it is always the problem that relevant technical staff faces.
Utility model content
The purpose of this utility model is the drawback for prior art, there is provided a kind of fluid-flywheel clutch failure that prevents
Burnt belt system protection device is transported, to realize the reliably protecting to transporting burnt belt system.
Problem described in the utility model is realized with following technical proposals：
A kind of fortune Jiao's belt system protection device for preventing fluid-flywheel clutch failure, composition, which includes being arranged on, transports burnt skin
Rotation speed detection unit on each bar equipment of conveyer with system, each rotation speed detection unit include proximity switch, middle relay
Device and multiple triggering blocks, multiple triggering blocks are fixed on one end of the bend pulley of corresponding belt feeder and edge is coaxial with bend pulley
Even circumferential is distributed, and the proximity switch is fixed in the frame of belt feeder and relative with multiple triggering blocks by switch bracket
Should, the control coil of the signal output termination auxiliary reclay of proximity switch, the normally opened contact one of the auxiliary reclay terminates
Power supply, a termination transport the PLC of burnt belt system.
The above-mentioned fortune Jiao's belt system protection device for preventing fluid-flywheel clutch failure, the proximity switch are used by switching
The three-wire system proximity switch of power supply power supply, the ac input end of the Switching Power Supply are connected by AC circuit breaker with power supply, directly
Stream output end is connected by dc circuit breaker with the power supply terminal of three-wire system proximity switch.
The above-mentioned fortune Jiao's belt system protection device for preventing fluid-flywheel clutch failure, the control line of the auxiliary reclay
On circle and it is connected to fly-wheel diode.
The above-mentioned fortune Jiao's belt system protection device for preventing fluid-flywheel clutch failure, each triggering block include a nut
With a bolt, the nut-welding on the bend pulley of belt feeder, the bolt be spun in nut and with proximity switch phase
It is corresponding.
The above-mentioned fortune Jiao's belt system protection device for preventing fluid-flywheel clutch failure, the triggering of the rotation speed detection unit
Block sets four.
The utility model directly monitors the rotating speed of bend pulley using rotation speed detection unit, because fluid-flywheel clutch failure must
Can so bend pulley be caused to stall, therefore carry out interlock protection to belt system using the monitoring signals can effectively prevent coupling device
Tail heap Jiao's accident caused by failure, ensure that the safety for transporting burnt belt system.

Embodiment
The utility model provides a kind of fortune Jiao's belt system protection device for preventing fluid-flywheel clutch failure, the device
After fluid-flywheel clutch malfunction and failure can be avoided to cause belt to stop, caused by the still strip operating of higher level's belt on windrow and damage
The accident of level belt.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model mainly includes triggering block 3, AC circuit breaker QF1, dc circuit breaker
QF2, Switching Power Supply T, proximity switch S, sustained diode, auxiliary reclay KA and PLC.
Specific implementation process is:
By the steel ring quartering of this grade of side of belt machine tail part bend pulley 2, M16 spiral shell is welded in the position of each Along ent
Mother, installs the hexagonal full screw thread bolt of M16 × 50, forms four triggering blocks 3, by the depth of regulating bolt precession nut,
The end face of four bolts is set to be located on the same perpendicular vertical with drum shaft 4.Opening for L-type is made with 50 × 5 band steel
Support 6 is closed, while is drilled in the facade of switch bracket 6, three-wire system proximity switch S is installed on hole, in belt feeder channel-section steel frame 5
Upper welding L-type switch bracket 6, makes proximity switch S end face relative with adjustable M16 bolt, and spacing is adjusted into 10mm,
When bend pulley 2 rotates, the hex bolts of M16 × 50 is just into proximity switch S sensor block, and often close to once, proximity switch is just
Action is once.Circuit, installation penetration pipe, laying control cable are designed, proximity switch S is accessed into electric control system.Belt feeder
Belt speed be 2m/s, the axis 580mm of 4 regulating bolt end face centers of installation apart from bend pulley 2.Bend pulley 2 rotates
One week used time 0.91s.Rotate one week proximity switch to act 4 times, the interval time for producing action signal is 0.23s, works as belt feeder
Just carry out the signal of a proximity switch during normal operation every 0.23s, auxiliary reclay KA control is given after proximity switch action
Coil power transmission, auxiliary reclay KA actions, its normally open contact closure are connected, and DC+24V signals are sent into PLC, PLC connects every 3 seconds
The number of pulses of receipts is compared with calculated value, you can fluid-flywheel clutch failure is judged whether, if fluid power idol be present
Clutch failure, then disconnect this grade of belt and shut down, alarm, after this grade of belt feeder is shut down, then cut off by programed interlocking between belt
Previous stage belt conveyor.
