Abstract
The utility model relates to a protection device is stopped to dragveyer system, including the sediment fill, the gyro wheel, the connection that set up in the sediment is fought are in chain on the gyro wheel, be provided with three angle sweeps on the chain, in fighting, installs the sediment movable lever, be provided with travel switch on the sediment fill lateral wall, the travel switch circuit is established ties to the stop button of dragveyer, works as the activity lever with during the travel switch contact, the dragveyer stop work. The travel switch circuit is established ties to the stop button at scene, the operation of dragveyer automatic shutdown, and central control room operating personnel discovery dragveyer stops the back, the right prediction scheme clearance of response in time and notice, the dragveyer just can continue normal operating under the circumstances of not having the harm.
Description
Technical field
The utility model relates to a kind of dragveyer stop protector.
Background technology
The dragveyer of full-closed structure cannot check the situation of internal operation; when big part waste residue falls into scraper plate inside, cause occurring dragveyer chain stuck owing to the running condition of dragveyer cannot be grasped in time, it is necessary to long-time shutdown maintenance; impact is produced, and wastes a large amount of manpower and materials.
Big part band after burning hooks scum and does not fall in slag bucket along dragveyer operation direction in operational process, but hang on triangle scraper plate, follow the bottom space of chain movement to rear, dragveyer inside is risen to again subsequently through afterbody later, it is stuck between triangle scraper plate and dragveyer base plate, cause scraper plate to be elevated, also make chain be elevated simultaneously thereupon. Owing to the waste residue of big block is stuck in chain inside, cause chain discontinuity, chain dislocation is overstepped the limit, time serious, also there will be the situation of chain fracture.
Practical novel content
The purpose of this utility model is the dragveyer stop protector providing a kind of available protecting dragveyer normally to run.
In order to solve above-mentioned technical problem; the technical solution adopted in the utility model is: a kind of dragveyer stop protector; comprise slag bucket; the roller being arranged in slag bucket, the chain being connected on described roller, described chain is provided with triangle scraper plate, is provided with active lever in described slag bucket; described slag bucket sidewall is provided with travel switch; described travel switch circuit is connected in series to the stop button of dragveyer, when described active lever contacts with described travel switch, and dragveyer stopping work.
Further, the square groove installing described active lever is offered in described slag bucket two side, and described travel switch is installed on the middle top of slag bucket sidewall side groove, can contact with described travel switch when described active lever moves up certain distance along described side's groove.
Further, at a distance of 5cm when described triangle scraper plate rises to plane same as described active lever. The scum being greater than 5cm when size is hung on triangle scraper plate, can encounter active lever during rising, drives active lever to rise and touches travel switch, makes travel switch action.
Travel switch circuit is connected in series to on-the-spot stop button, and dragveyer is automatically out of service, and Central Control Room operator respond in time and notify that right prediction scheme is cleared up after finding that dragveyer stops, and dragveyer just can continue normal operation when harmless.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide and does not form improper restriction of the present utility model to of the present utility model it is further understood that the part of formation the application, in the accompanying drawings:
Fig. 1 is the utility model stop protector structural representation.
Fig. 2 is the utility model travel switch and active lever fit structure schematic diagram.
Fig. 3 is the utility model control circuit structural representation.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail, it is used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
With reference to accompanying drawing 1,2; a kind of dragveyer stop protector; comprise slag bucket 1; the roller 2 being arranged in slag bucket 1, the chain 3 being connected on described roller, described chain 3 is provided with triangle scraper plate 4, is provided with active lever 5 in described slag bucket 1; described slag bucket 1 sidewall 6 is provided with travel switch 8; described travel switch 8 circuit is connected in series to the stop button of dragveyer, when described active lever 5 contacts with described travel switch 8, and dragveyer stopping work.
Concrete, the square groove 7 installing described active lever 5 is offered in described slag bucket 1 two side 6, described travel switch 8 is installed on the middle top of slag bucket sidewall side groove 7, can contact with described travel switch 8 when described active lever 5 moves up certain distance along described side's groove 7.
Concrete, described triangle scraper plate 4 rises to during described active lever 5 same plane at a distance of 5cm. The scum being greater than 5cm when size is hung on triangle scraper plate, can encounter active lever during rising, drives active lever to rise and touches travel switch, makes travel switch action.
With reference to, shown in accompanying drawing 3, travel switch and electronic relay illustrate owing to dragveyer motor belt motor step-down gear runs, electric current only 2.5A��2.7A during actual motion, over current of motor also just reaches 4A��5A. For conventional thermal formula current relay, little overcurrent need the long period just can action, be easy to miss action moment; Practical situation are that equipment damages, and thermo-relay just action, can not play a protective role to dragveyer. Use quiescent current thermo-relay instead, utilize the feature that it is quick, accurate and stable, can play a protective role to during dragveyer current overload.
Owing to quiescent current rly. does not exist the inverse time limit function of thermal relay, motor bigger electric current when starting can cause current relay flase operation, therefore control circuit leaf needs adjustment to increase start-up study device. Control circuit after adjustment, when motor start time 5 seconds in current relay do not work, add start-up study device; After current of electric is stable, current relay normally enters operation, and electric current is transferred to 3A.
Above the technical scheme that the utility model embodiment provides is described in detail, applying specific case herein the principle of the utility model embodiment and enforcement mode to have been set forth, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, all will change in embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
