It was found that the problem of, it reduces scrapper conveyor and the probability of catastrophe failure occurs, by big Fault Control in budding state, saved failure
Processing cost alleviates the labor intensity of service personnel, saves the repair time, makes to jump chain and chain rupture protection is sensitiveer；To extension
The scrapper conveyor service life guarantees that coal preparation plant normally and efficiently produces and is of great significance, can widely popularize in coal separation industry.
Detailed description of the invention
In order to illustrate more clearly of the utility model embodiment technical solution, will make below to required in embodiment description
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model in order to more clearly
Illustrate the utility model embodiment or technical solution in the prior art, for those of ordinary skill in the art, is not paying
Out under the premise of creative work, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is utility model works schematic illustration.
Specific embodiment
A kind of scrapper conveyor Anti-inclining protective device as shown in Figs. 1-2, including sensor 1, the sensor 1 are set to detection
8 top of hole, and be fixedly arranged on firm banking 9, the detection hole 8 is opened in 5 both ends of cover-board for scraper machine, and the sensor 1 is used for
The synchronous situation of board ends is scraped in detection, and is electrically connected single-chip computer control system.
Further, the sensor 1 is the electric transducer that diffuses, and respectively sets one at 5 both ends of cover-board for scraper machine.
Further, the single-chip computer control system will test signal and be transmitted to central station of floating dock PLC system.
Preferably, the sensor 1 is externally provided with shield 2.
To prevent continuation band " disease " after scrapper conveyor minor failure from running, tries to improve scrapper conveyor protection, allow scrapper conveyor light
After micro- failure, fault-signal is sent back into centralized control center, timely parking checking processing at the first time, in order to avoid cause bigger thing
Therefore.Following Curve guide impeller is made thus：By analysis and summary, scrapper conveyor is when operating normally, upper layer scraper plate 3 and lower layer's scraper plate 4
Always keep vertical with slideway 6, if scrapper conveyor occurs to jump chain, falls chain, chain rupture, scraper plate will be tilted, not vertical with slideway 6.Benefit
With this operation characteristic of scrapper conveyor, the high precisely sensor 1 (laser diffusion sensor) of 3 both ends of scraper plate installation, detection on upper layer
The verticality of upper-lower scraper and slideway 4, the i.e. synchronous detection of scraper plate.
By installing sensor 1 on cover-board for scraper machine 5, two-way detection signal is sent into single-chip computer control system, monolithic
Two pulse signals are carried out logic analysis processing by machine, are made to the working condition of scrapper conveyor and promptly and accurately being judged.Scrapper conveyor exists
Normal and malfunction is detected when operation, when scrapper conveyor occurs to jump chain or chain rupture, scraper plate machine scraper can generate tilt phenomenon,
When tilt angle is greater than the permissible value of setting, scrapper conveyor unequal protection device will be acted, and scrapper conveyor is shut down, this makes it possible to
Failure, is preferably minimized limit by promptly and accurately judgement and alarm parking.
The utility model installation and use process：
Open two detection holes 8 in the top blind flange 5 of scraper plate box body 7, when aperture notices that the line of two detection holes 8 is wanted
With below cover board 5 upper layer scraper plate 3 and lower layer's scraper plate 4 it is parallel.It is the premise of aperture that scraper plate is vertical with both ends slideway 6, and just
The standard state often run.Diffusing reflection sensor 1 simultaneously wiring and installation shield 2 are installed in detection hole 8.In single-chip microcontroller
Signal logic processing, data debugging are done in control system, and this signal is transferred to main central station of floating dock PLC system.
Utility model device strong applicability, structure are simple, easy to use, solve scrapper conveyor minor failure and are difficult in time
It was found that the problem of, it reduces scrapper conveyor and the probability of catastrophe failure occurs, by big Fault Control in budding state, saved failure
Processing cost alleviates the labor intensity of service personnel, saves the repair time, makes to jump chain and chain rupture protection is sensitiveer；To extension
The scrapper conveyor service life guarantees that coal preparation plant normally and efficiently produces and is of great significance, can widely popularize in coal separation industry.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
