Description
Technical field
The utility model relates to the technical field of the matching used cleaning cinder equipment of boiler plant, is specifically related to a kind of alarm protecting apparatus of scraper type slag extractor.
Background technology
Slag remover is the equipment of the cinder with coal-burning boiler after matching used cleaning boiler combustion.Slag remover is arranged at below boiler slag mouth, the slag remover that current boiler industry adopts adopts motor-belt pulley-decelerator transmission to provide operation power mostly, sprocket wheel chain is driven to rotate, chain being provided with the scraper plate for striking off cinder, by the shuttling movement of scraper plate, the cinder fallen in slag remover body being transported to outside.
But scraper type slag extractor compares the equipment easily gone wrong in boiler accessory machinery all the time; mainly easily there is stuck phenomenon when there being large cinder to fall into receipts cinder notch because be in operation or wear and tear due to long-play; occur that serious wear load is increasing; thus shining into motor overload heating, thermal protection for motors switch trip is shut down.Circuit can be caused like this to generate heat be oxidized, the decreasing insulating of motor shortens service life.
Also do not have a kind of when cinder plate generation load becomes large in the market, operation personnel can know the device occurring that situation can process in time at once.
Utility model content
In order to solve the problem, a kind of alarm protecting apparatus of scraper type slag extractor disclosed in the utility model, when situation appears in mucking machine and alarm, prompting personnel process.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of alarm protecting apparatus of scraper type slag extractor, it comprises motor, belt gear, it is characterized in that: also comprise clutch transmission and accident warning device, described clutch transmission is arranged on a rotating shaft, described clutch transmission comprises the fast pulley arranged from inside to outside successively, floating roller, compression spring and Load Regulation nut, described motor is connected with floating roller by chain or belt, described fast pulley is fixedly installed on described rotating shaft, described floating roller can slide along rotating shaft axis direction, described floating roller and described fast pulley are equipped with the ladder type tooth engaged of mutually mating, described floating roller passes through the mutual compact siro spinning technology of ladder type tooth engaged with described fast pulley under the active force of compression spring, described accident warning device comprises travel switch and alarm lamp, and described travel switch is arranged on the outside of described floating roller, and described travel switch connects described alarm lamp.
Described tooth engaged is 30 ° of trapezoidal-structures, and the distance between described travel switch and described floating roller is shorter than the height of described trapezoidal-structure.
Described clutch transmission also comprises a self-locking nut, and this self-locking nut is arranged on outside described Load Regulation nut, with described Load Regulation nut close contact.
Described compression spring is conical stage clip, and the large end of this conical stage clip contacts with floating roller, and small end contacts with Load Regulation nut.
Bearing is provided with between described floating roller and described rotating shaft.
The utility model has the advantage of: the utility model is by arranging clutch transmission and accident warning device, motor and rotating shaft is connected by clutch transmission, when scraper type slag extractor occurs that serious wear load is increasing, when load exceeds standard, namely when load exceedes the snap-in force between floating roller and fast pulley, compression spring in clutch transmission is compressed, floating roller outwards exits chimeric, withstand travel switch and produce closed action, send signal to alarm lamp and console, operations staff can understand fault in time, on-call maintenance.
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present embodiment;
Fig. 2 is clutch transmission and the accident warning device structural representation of the present embodiment.
In figure: 1. clutch transmission, 11. fast pulleys, 12. floating rollers, 13. compression springs, 14. Load Regulation nuts, 15. self-locking nuts, 2. accident warning device, 21. travel switches, 22. alarm lamps, 3. rotating shaft.
Detailed description of the invention
Embodiment, see Fig. 1 ~ Fig. 2, the alarm protecting apparatus of the scraper type slag extractor that the present embodiment provides, it comprises motor, belt gear, also comprise clutch transmission 1 and accident warning device 2, described clutch transmission 1 is arranged on a rotating shaft 3, described clutch transmission 1 comprises the fast pulley 11 arranged from inside to outside successively, floating roller 12, compression spring 13 and Load Regulation nut 14, described motor is connected with floating roller 12 by chain or belt, described fast pulley 11 is fixedly installed on described rotating shaft 3, described floating roller 12 can slide along rotating shaft 3 axis direction, described floating roller 12 and described fast pulley 11 are equipped with the ladder type tooth engaged of mutually mating, described floating roller 12 passes through the mutual compact siro spinning technology of ladder type tooth engaged with described fast pulley 11 under the active force of compression spring 13, described accident warning device 2 comprises travel switch 21 and alarm lamp 22, and described travel switch 21 is arranged on the outside of described floating roller 12, and described travel switch 21 connects described alarm lamp 22.The present embodiment is by arranging clutch transmission 1 and accident warning device 2, motor and rotating shaft 3 is connected by clutch transmission 1, when scraper type slag extractor occurs that serious wear load is increasing, when load exceeds standard, namely when load exceedes the snap-in force between floating roller 12 and fast pulley 11, compression spring 13 in clutch transmission 1 is compressed, floating roller 12 outwards exits chimeric, withstand travel switch 21 and produce closed action, send signal to alarm lamp 22 and console, operations staff can understand fault in time, on-call maintenance.
Described tooth engaged is 30 ° of trapezoidal-structures, and the distance between described travel switch 21 and described floating roller 12 is shorter than the height of described trapezoidal-structure, and ensure that floating roller 12 is in the process away from fast pulley 11, floating roller 12 can withstand travel switch 21 and produce closed action.
