Description
Technical field
Harbour machinery detecting tool technical field is the utility model is related to, especially belongs to a kind of port machine rotating machinery failure
Monitoring device.
Background technology
The rotating machinerys such as belt conveyor, grinder, disintegrating machine, pump, mixer and deduster, easily there is belt and beat
Mechanical breakdown that cunning, belt fracture, card turn, slow-speed, moving axis shearing and overload, driving chain come off etc., at present when above-mentioned machine occurs
During tool failure, because that can not find in time, even if equipment may be caused to power off and damage, not only increase the maintenance of equipment into
This, there is also serious job safety hidden danger.
The content of the invention
The purpose of this utility model is to provide a kind of port machine rotating machinery fault monitoring device, to reach practicality
By force, accuracy of detection is high and ensures that port machinery equipment is safe for operation, saves the purpose of the maintenance cost of equipment.
Machine rotating machinery fault monitoring device in port provided by the utility model, it is characterised in that approach and open including speed
Pass, bindiny mechanism and metal blade, bindiny mechanism include connecting bracket and double threaded screw, and connecting bracket is fixed to rotation and set
On the end cap that standby host seat is put, wherein, double threaded screw one end connects end part of driving shaft, the other end of double threaded screw by nut
Metal blade is connected, speed proximity switch is attached in connecting bracket, speed proximity switch, the time relay and the contact
Device, coordinate start button, access in the control circuit of rotating machinery, constitute stall observation circuit.
Further, it is additionally provided with scram button in the stall observation circuit.
Further, the metal blade has two symmetrical fan leafs, rotates to per fan leaf end and is connect with speed
It is corresponding with the sensitive surface of speed proximity switch while closely switching closest position.
Machine rotating machinery fault monitoring device in port provided by the utility model, can monitor rotating machinery power transmission shaft in real time
Rotating speed, the stuck stall of pre- anti-rotation device the occurrence of, by the metal blade on power transmission shaft, utilize electricity
The principle of magnetic induction gives speed proximity switch pulse signal, such as：When metal blade is turned to from speed proximity switch 4-8 millimeters
Apart from when, be a pulse, energization spot speed proximity switch prolongs time relay adhesive by the time relay of series winding
When for setting number of seconds, such as：The circle of equipment drive axis one needs to give speed proximity switch two pulses, if speed approaches
Switch is set in 10 seconds, and equipment rotates a circle and is less than 10 seconds, and speed proximity switch passes through the time relay adhesive of series winding, equipment
Operating；It is more than 10 seconds when equipment rotates a circle, speed proximity switch is thought stuck stall has occurred, and passes through the time relay of series winding
Device dead electricity disconnects, motor stopping, protection equipment.In summary, the utility model has the maintenance cost for saving equipment and guarantor
Demonstrate,prove port machinery equipment safety, improve the good effect of job safety guarantee.
Brief description of the drawings
Accompanying drawing part discloses the utility model specific embodiment, wherein
Fig. 1 is structural representation of the present utility model；
Fig. 2 is electrical schematic diagram of the present utility model.
Embodiment
As shown in Figure 1-2, machine rotating machinery fault monitoring device in port provided by the utility model, including speed are approached and opened
1, bindiny mechanism and metal blade 2 are closed, wherein, the metal blade has two symmetrical fan leafs, per fan leaf end
It is corresponding with the sensitive surface of speed proximity switch while rotating to the position closest with speed proximity switch；Connection machine
Structure includes connecting bracket 3 and double threaded screw 4, and connecting bracket is fixed on the end cap 6 of the position of rotating machinery support 5, wherein, it is double
Head screw rod one end passes through nut 7, connection power transmission shaft 8 end, the other end connection metal blade of double threaded screw, speed proximity switch
It is attached in connecting bracket, the speed proximity switch, time relay R and contactor C, coordinates start button QA, access
In the control circuit of rotating machinery, stall observation circuit is constituted.In the present embodiment, the speed proximity switch uses RD-
The delay adjustable speed proximity switch of type III.
Operation principle of the present utility model is：The master switch QS of rotating machinery is closed, presses start button QA, contactor C
Electric adhesive, the main contact adhesive of contactor are obtained, the motor M of rotating machinery is operated, and the normally open contact of contactor obtains electric adhesive, motor
M starts to be rotated with metal blade, time relay R adhesives, the normally opened contact adhesive of the time relay, is now unclamped startup and is pressed
Button QA.In the present embodiment, when speed proximity switch is set in 10 seconds, metal blade rotates a circle, speed proximity switch
2 pulse signals can be received, then when speed proximity switch received 2 pulses in 10 seconds, i.e., the motor of rotating machinery rotates just
Often, circuit maintains normally state；If speed proximity switch can not receive 2 pulses, i.e., now the motor of rotating machinery has
The hidden danger of the failures such as stall, now, stall observation circuit turn-off time relay, the contact dead electricity of the time relay are opened, and are turned
The motor of dynamic equipment stops operating, and so as to prevent the badly damaged of equipment, protects equipment, also saves the maintenance of equipment
Cost.
Preferably, in order to meet the timely power-off demand in operation process, jerk is additionally provided with the stall observation circuit
Button TA, when motor is in operation process, when pressing scram button, motor can stop operating immediately.
