Abstract
The utility model relates to a chain breaking protection device of a scraper conveyor, which is characterized by comprising an approach switch, an upper band iron, a rotating sleeve, a transmission rubber belt, a cross beam parallel to a conveyor scraper, and a baseplate arranged on the cross beam, wherein the approach switch is fixedly arranged on the baseplate through an approach switch mounting plate, the transmission rubber belt is connected with the upper band iron arranged in front of the approach switch through the rotating sleeve, the rotating sleeve is arranged on a sleeve bracket through a pin shaft, and the sleeve bracket is arranged on the baseplate. The transmission rubber belt is connected with the rotating sleeve through a lower band iron. The baseplate is also provided with a fixed mounting hole. The device disclosed by the utility model has a simple structure, the approach switch is easy to install, the distance between the approach switch and the band iron to be measured is easy to adjust, and the horizontal distance between the approach switch and the band iron to be measured can not be changed after adjustment, so the approach switch can not be damaged.
Description
Technical field
The utility model relates to chain breakage protection device, a kind of specifically chain breakage protection device that is used for slat conveyer.
Background technology
Slat conveyer has a wide range of applications in industrial and mining enterprises, is mainly used in the shipping bulk material.Slat conveyer chain rupture fault can cause more serious accident if discovery is untimely, influences ordinary production for a long time.Traditional chain rupture safety method is normally respectively installed one near switch in two scraper chain slideway outsides; Insert the PLC system near on-off signal; PLC judges whether to have taken place the chain rupture fault through detecting two signals near switch, if detect the chain rupture fault then cut off motor power.This traditional chain breakage protection device has following shortcoming: big near the switch installation difficulty on the one hand, and very little near the actual induction distance of switch, and the activity space of scraper chain is relatively large, therefore requires too high to setting accuracy.When sneaking into material when the scraper chain pine or in the scraper chain slideway on the other hand, scraper chain or lump material are easy to break near switch, may cause near switch in addition and can't sense signal, thereby cause flase alarm.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of slat conveyer chain breakage protection device is provided.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: a kind of slat conveyer chain breakage protection device; It is characterized in that: comprise near switch, go up band iron, turnbarrel, drive belt, be parallel to the crossbeam of conveyer scraper and be arranged on the base plate on the crossbeam; Said near switch through being fixedly installed on the base plate near the switch adapter plate; Drive belt is connected with the last band iron that is arranged near switch the place ahead through turnbarrel, and said turnbarrel is arranged on the bush support through bearing pin, and bush support is arranged on the base plate.
Said drive belt passes through down, and band iron is connected with turnbarrel.
Also be provided with the fixed installation hole on the said base plate.
The utility model is simple in structure, near the switch easy mounting, regulates easily near the distance between switch and the tested band iron, mixes up the back and can not change near the horizontal throw between switch and the tested band iron, therefore can not broken.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model mounting structure scheme drawing.
Fig. 3 is the utility model operating structure scheme drawing.
Mark among the figure: 1, near switch, 2, go up band iron, 3, turnbarrel, 4, drive belt, 5, crossbeam, 6, base plate, 7, near the switch adapter plate, 8, bearing pin, 9, bush support, 10, band iron down, 11, the fixed installation hole, 12, scraper plate, 13, scraper chain.
The specific embodiment
Shown in figure one: a kind of slat conveyer chain breakage protection device comprises near switch 1, goes up band iron 2, turnbarrel 3, drive belt 4, is parallel to the crossbeam 5 of conveyer scraper 12 and is arranged on the base plate 6 on the crossbeam 5.Near switch 1 through being fixedly installed on the base plate 6 near switch adapter plate 7.Drive belt 4 is connected with the last band iron 2 that is arranged near switch 1 the place ahead through turnbarrel 3.Turnbarrel 3 is arranged on the bush support 9 through bearing pin 8, and bush support 9 is arranged on the base plate 6.Said drive belt 4 passes through down, and band iron 10 is connected with turnbarrel 3.Also be provided with fixed installation hole 11 on the said base plate 6.Fixed installation hole 11 can be provided with a plurality of, and present embodiment is provided with 2 fixed installation holes 11, makes things convenient for the installation of chain breakage protection device.
Shown in figure two: two fender guards are fixedly installed on the rack beam 5; Two signals near switch 1 insert the PLC system, when slat conveyer moves, and the drive belt 4 of two devices of scraper plate 12 collisions; Last band iron 2 motions on the driven rotary sleeve 3; Thereby cause that near switch 1 action under the normal circumstances, it is a normal value that PLC detects two time differences (Δ t) near switch 1 action.
Shown in figure three: when slat conveyer generation chain rupture; One side scraper chain 13 breaks off and causes scraper plate 12 run-off the straights; This moment two ends drive belt 4 to collide time of scraper plate 12 can difference a lot; Time difference (Δ t) can be obviously greater than normal value, and PLC can judge that in view of the above fault has taken place slat conveyer, in time breaks off the dynamo-electric source of scraper plate.
