Description
Technical field
This utility model is related to the conveyer belt protector of ribbon conveyer, in particular, is related to a kind of flicker of band and refers to
Show the conveyer belt pull switch of lamp.
Background technology
At present, in the conveying of the wide variety of ribbon conveyer of the industries such as electric power, colliery, building materials, harbour, metallurgy, cement
Band protection device, is a kind of conveyer belt pull switch, also known as emergency stop switch, is when ribbon conveyer has an accident, tightly
A kind of conveyer belt protector of jerk machine.Conveyer belt pull switch includes housing, armed lever, reseting handle, cam, fine motion are opened
Close.Conveyer belt pull switch is installed in the frame of belt conveyor both sides, with drawstring (steel wire rope) along conveyer both sides handle
Switch couples together.The distance between two pull switches are 25～30m, and the steel wire rope of the diameter 4mm of employing connects, elastic suitable
Degree.In order to reduce steel wire rope deadweight, malfunction is produced on switch impact, a filler ring supporting steel is welded on the frame at 3m
Cord is it is ensured that normal run.
The effect of conveyer belt pull switch：
1st, emergency shutdown → when abnormal conditions in ribbon conveyer running, as long as draw drawstring nearby
Just ribbon conveyer can be stopped, it is to avoid the generation of the person or equipment breakdown.Such as in hopper Severe blockage, great wheel is rolled
Cylinder skids, and sharp object scratches belt, when serious blocking package, implements emergency shutdown.
2nd, No starting → when maintainer is not withdrawn or remains in other abnormal conditions, as long as pull switch is locked
It is scheduled on stop position, just without worrying ribbon conveyer by error starting, the safety of maintainer also just has guarantee.
The operating instruction of conveyer belt pull switch：
1st, shut down：It is lifted up or depresses drawstring, promote armed lever to rotate, touch microswitch and lock, until artificial hand
Dynamic reset.
2nd, reset：Move reseting handle, armed lever returns to vertical position, pending fault can be started shooting after having processed.
3rd, when ribbon conveyer normally runs, drawstring must not be touched, in order to avoid hang-up.
The conveyer belt pull switch of prior art has the disadvantage that：
1st, the mode of connection of current pull switch：Opened point is in parallel, or the series connection of normally closed point.In switch, generally there is two-way
Contact, a road send MCC to trip, and a road send program-control cabinet to trip.Pull switch is laid according to the length of conveyer belt, generally every 30 meters
One pull switch is installed.Some conveyer belts are longer (length even having several kilometers having), and ribbon conveyer both sides need to install
More than ten pull switch.After switch motion, which switch motion operations staff cannot find in time is gone to reset, need to be in belt two
Side is found back and forth, bothers very much.
2nd, after the switch having uses the long period, spring loosens, and switchs malfunction, and which switch operations staff's handss can not find
Malfunction.
3rd, after microswitch contact malfunction, maintainer cannot judge it is which pull switch action.Searching fault
When, each switch connection box need to be opened, fishing line one by one, see it is which microswitch action, the handling failure time is relatively
Long, impact produces.
Content of the invention

Fixed；It is characterized in that：Flashing indicator light module is set up below described microswitch, perforate on housing, diode flicker is installed and refers to
Show lamp, flashing indicator light module is drawn both threads and connect diode flashing indicator light.
Further, described flashing indicator light module adopts full-wave rectifying circuit, diode decompression mode, and goes here and there in the loop
Enter current-limiting resistance, customer power supply can meet L1, L2, when COM line meets L1 or L2, loop all can be made to turn on, diode flicker instruction
Lamp is lighted.
Further, described flashing indicator light module string is between the COM line and NO of microswitch and binding post, or COM
Between line and NC.
Further, described diode flashing indicator light diameter 10mm, opening diameter 14mm on housing, and use inside lampshade
704 silicone rubber are fixed.
Further, the circuit board of described flashing indicator light module, with epoxide-resin glue fill in plastic casing.
This utility model compared with prior art, due to flashing indicator light module being installed additional on conveyer belt pull switch and connects
Connect diode flashing indicator light, after a certain switch motion, display lamp flashes, and points out operations staff and this drawstring of maintainer
Switch motion；When display lamp flicker, point out this switch motion of field personnel correct, when display lamp does not flash, say
This switching signal bright is not delivered to program control, need to ascertain the reason；After a certain switch malfunction, display lamp flashes, and points out maintainer
The microswitch of this switch is broken or this switch does not have reset, finds out trouble point rapidly, and timely handling failure decreases and sets
Standby idle time.
This utility model is used for the conveyer belt protector of ribbon conveyer, on the premise of system wiring does not increase N line,
Achieve display lamp and light flash for prompting warning, facilitate the searching of trouble point, improve work efficiency.
