Description
Technical field:
The utility model relates to a kind of warning devices torn using mine is fallen with re-detection conveyor belt.
Background technique:
Conveyer belt used in existing belt conveyor is hardy type steel cord belt, and totally 11, width is from 800-
1600mm, longest adhesive tape 274m will cause halt production after conveyor belt tearing, serious to Influence of production.Tearing is detected in advance
Belt can reduce maintenance time, to reduce down time.
Utility model content:
In order to overcome the above problem of the existing technology, the purpose of the utility model is to provide a kind of uses to fall mine counterweight
Detect the warning device of conveyor belt tearing.
Above-mentioned purpose is realized by following technical scheme:
A kind of warning device torn using mine is fallen with re-detection conveyor belt, composition includes: rack, in the machine
Seesaw is installed, described seesaw one end is placed with counterweight, and other end upper surface is equipped with iron plate, lower surface installation on frame
Have close to switch, inclined baffle is provided with above the iron plate, the baffle is fixed on the rack, in the machine
The bracket that counterweight is supported when be provided on frame in equilibrium state, is provided in the rack in nonequilibrium condition
When for triggering the triggering bracket of alarm, it is described to be connect close to switch with sound-light alarm starter.
The utility model has the beneficial effects that
The utility model is that funnel, which is fallen at 1.5 meters of direction of advance of mine point return belt, pacifies in belt conveyor adhesive tape lower layer
Scraper plate is filled, falls mine to lower layer's adhesive tape after conveyer belt tearing, scraper plate scrapes mineral at following lever splicing, after mineral overweight counterweight
It deflects to close to after inductive switching area and alarms.
The utility model reduces belt tearing accident impact, average to cause adhesive tape to tear 90 meters or more by original accident every time
It foreshortens to 30 meters average；It reduces after adhesive tape tearing failure occurs and resumes production the time used, be down within 16 hours 8 hours by original；And
Shi Faxian failure avoids scrapping because of whole conveyor belt caused by personal monitoring is ineffective instead of personal monitoring.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.In figure, 1 is scraper plate, and 2 be the belt of conveyor belt, and 3 be carrying roller,
4 be counterweight, and 5 be bracket, and 6 be baffle, and 7 be iron plate, and 8 is, close to switch, 9 are seesaw, and 10 be triggering bracket.
Attached drawing 2 is the schematic diagram that the seesaw of the utility model turns to triggering alert locations.
Specific embodiment:
Embodiment 1:
A kind of warning device torn using mine is fallen with re-detection conveyor belt, composition includes: rack, in the machine
Seesaw is installed, described seesaw one end is placed with counterweight, and other end upper surface is equipped with iron plate, lower surface installation on frame
Have close to switch, inclined baffle is provided with above the iron plate, the baffle is fixed on the rack, in the machine
The bracket that counterweight is supported when be provided on frame in equilibrium state, is provided in the rack in nonequilibrium condition
When for triggering the triggering bracket of alarm, it is described to be connect close to switch with sound-light alarm starter.
For the setting of this warning device under weight plate below mine funnel, ore transmits lower layer's belt at about 1.5 meters of opposite direction
On non-working surface, a scraper plate is set on lower layer's belt of conveyor belt, this alarm dress is provided with below the scraper plate
The inclined baffle set, corresponding lower section are exactly iron plate and close switch.When there is conveyor belt Splitting, ore passes through
Crack is fallen on lower layer's belt of conveyor belt, and is moved at scraper plate with ore transmission opposite direction, when the ore fallen into reaches
To after constant weight, the bending of lower layer's belt is being pressed against, the baffle of lower part has supporting function to curved lower layer's belt, and under protecting and holding in the palm
Layer belt with iron plate until be in contact, so that seesaw rotates, close switch touch trigger bracket causes alarm signal.
Embodiment 2:
According to described in embodiment 1 using warning device of the mine with the tearing of re-detection conveyor belt is fallen, belt tearing is detected
Device is installed under weight plate below mine funnel, and ore transmits on lower layer's belt non-working surface at about 1.5 meters of opposite direction, containing falling
Mine collects, tearing judgement, alarms and trigger three parts.
One, mine collection is fallen
Two carrying rollers are installed below lower layer's belt and make belt tension, belt is avoided to shake, carrying roller spacing is 1.5 meters；
Mine plate is scraped with the colloid of belt in angle of 45 degrees in two carrying roller intermediate belt inner surface installations to collect for mineral.
Two, tearing judgement
It tears judgment means structure: using one piece of 800*400 plank, two sides are respectively installed 1 bearing and are used among long side
Support board simultaneously makes after plank stress convenient for rotation；Side short side scrapes mine plate bring ore for accepting, and the other side installs additional
About 100 grams of counterweights (weight-adjustable), counterweight lateral plates lower section install support frame additional, avoid plate face mobile.When ore accepts upper side
Mineral are accumulated beyond after counterweight, plank can do counterclockwise movement by the center of circle of bearing.
Three, detection device
It falls mine in plank and accepts and fix one piece of band iron on side end face, install one close to opening in band iron end face travel track side
It closes, when falling mine more than balance weight, plank overturning is connected when band iron is moved to close to inductive switching area close to switch motion.With
Acoustic-optic alarm starting is driven close to switch conduction, acoustic-optic alarm is mountable at the scene, belt operation room, Central Control Room etc.
Region, it is mountable multiple.
The signal generated by tearing is sent to automatic control DCS system and realizes that alarm or the interlocking of belt stop.
