Description

Conveyor delivery chain deviation correcting device

The utility model relates to a kind of device that the chain-linked conveyer chain wanders off of correcting, and relates in particular to a kind of device that the chain-linked conveyer chain wanders off in the work backhaul of correcting.

The chain-linked conveyer convey materials is the thrust of material generation and the internal friction of material itself to be finished in operational process by the scraper plate on the chain, chain is out-of-level owing to installing in backhaul, reasons such as discontinuity, can cause chain to wander off, the scraper plate of chain contacts with casing in motion process, thereby cause faults such as casing is worn out by scraper plate, scraper plate distortion, influence the normal operation of conveyer.For addressing this problem, common way is: the voussoir that is the inclined-plane is installed on the casing of conveyor chain backhaul scraper plate both sides again, the inclined-plane of voussoir is relative with scraper plate on the chain, voussoir is that high-abrasive material is made, when chain wanders off, scraper plate on the chain contacts with the voussoir inclined-plane, scraper plate on the chain is subjected to the effect on a side voussoir inclined-plane, produce one with the chain direction opposite effect power that wanders off, thereby make chain and scraper plate return to the normal position, reach and correct the effect that chain wanders off.But this deviation correcting device exists two problems: the one, and when the scraper plate on the chain contacts with voussoir and produces relative motion, be cliding friction, its friction force is bigger, the component opposite that produces when adding the voussoir inclined-plane with sense of motion with the scraper plate mutual action, the resistance increase is very big, the consumption of power when having increased conveyer work; The 2nd, the wearing and tearing of voussoir material are more serious, generally adopt hard-casting as voussoir, and its wear-out period is 6-8 month; And adopt the ordinary steel iron material as voussoir, and its wear-out period has only 4-6 month, and therefore, voussoir will often be changed, and maintenance is trouble.

The purpose of this utility model is that a kind of conveyor delivery chain deviation correcting device will be provided, it can be corrected chain effectively and wander off in backhaul, avoid scraper plate on the chain and casing to come in contact and rub, reduce the friction drag in the chain operational process.

The purpose of this utility model is to realize like this, conveyor delivery chain deviation correcting device, the casing that comprises conveyer, be installed in the drive sprocket and the driven sprocket of casing two ends midway location, be installed in the base plate of two bottom of shell, be installed in the upper rail of two casing middle upper portion positions, be fixed on the carriage that is used to install guide rail on the casing, be installed in the chain between drive sprocket and the driven sprocket and be fixed on scraper plate on the chain, the two ends of scraper plate are hypotenuses, scraper plate hypotenuse and its work base are the acute angle of 60-80 degree, upper rail by if in the joint guide rail form, between guide rail and guide rail, have at interval, the carrying roller catch wheel device is installed at the interval, the carrying roller catch wheel device is by carrying roller, gear wheel and axis of revolution are formed, two gear wheels are installed in the both sides of carrying roller respectively, axis of revolution passes carrying roller, the axle center of gear wheel, the two ends of axis of revolution are installed on the casing of its both sides.

The utility model has the advantages that: this apparatus structure is simpler, stable during work, reliable, mechanical breakdown is few, easy to maintenance, long service life, and,, saved energy consumption so reduced the consumption of power when conveyer is worked owing to replaced the part cliding friction with the part friction of rolling in the chain operational process.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model conveyor delivery chain deviation correcting device;

Fig. 2 is the partial top view of the utility model conveyor delivery chain deviation correcting device;

Fig. 3 is a conveyor delivery chain deviation correcting device shown in Figure 2 cutaway view along the A-A line;

As Figure 1-3, the conveying machinery part of chain-linked conveyer convey materials is made up of some joint bodies 1, every joint body 1 is by casing 4, base plate 5 and top board 6 are formed, the both sides of body 1 are casings 4, base plate 5 is installed in the bottom of two casings 4, top board 6 is installed in the top of two casings 4, two rotating drive sprockets 2 and driven sprocket 3 are separately positioned in the body 1 at conveyer two ends, drive sprocket 2, the axle mounting of driven sprocket 3 is on casing 4, drive sprocket 2, driven sprocket 3 is the midway location between casing 4 all, between drive sprocket 2 and driven sprocket 3, be provided with a chain 9, be provided with scraper plate 13 on each joint of chain 9, all there is hypotenuse at the two ends of scraper plate 13, the hypotenuse of scraper plate 13 and its work base are acute angle, when convey materials, the work base of scraper plate 13 contacts with base plate 5, be provided with several carriages 8 in the position, middle and upper part of body 1, carriage 8 is fixed on the casing 4 of body 1 both sides, upper rail 7 is arranged on the middle part between the casing 4, and be installed on the carriage 8, upper rail 7 by if in the joint discontinuous guide rail form, have one at interval between per two joint upper rails 7, be provided with the both sides that two gear wheels 11 of carrying roller catch wheel device are installed in carrying roller 10 respectively at the interval, axis of revolution 12 passes the center of carrying roller 10 and gear wheel 11 and adopts bearing 14 axis of revolution 12 to be installed on the casing 4 of its both sides, the slightly larger in diameter of gear wheel 11 is in the diameter of carrying roller 10, the high workload point of carrying roller 10 is a little more than the end face of upper rail 7, and the acute angle on scraper plate 13 hypotenuses and its work base is between the 60-80 degree.The backhaul chain of chain 9 is arranged on above the carrying roller 10 between upper rail 7 and two gear wheels 11.

During the chain-linked conveyer convey materials, under dynamic action, drive sprocket 2 rotates and drives chain 9 motions, driven sprocket 3 also and then rotates, in the bottom of body 1 and the chain 9 of being close to 5 motions of body 1 base plate be mode of operation, at this moment be fixed on the material that the scraper plate 13 on the chain 9 drives on the base plates 5 and travel forward together; 9 motions backward on the carrying roller 10 between upper rail 7 and the gear wheel 11 of chain on body 1 top, thus make continuously convey materials of chain 9.Chain 9 in the course of the work, because it is out-of-level that conveyer is installed, perhaps chain 9 unbalance stress, chain 9 just can wander off on upper rail 7 and carrying roller 10 to the left or to the right, at this moment the scraper plate 13 of chain 9 just also rotates with gear wheel 11 contacts of carrying roller 10 1 sides, the scraper plate 13 of a side is just driven and lifts and leave carrying roller 10 and move by the gear wheel 11 of carrying roller 10 1 sides on the chain 9, when being driven certain altitude by gear wheel 11 along with the scraper plate 13 of a side on the chain 9, between the inclined-plane of scraper plate 13 ends and the baffle plate 11 because the action of gravity of chain 9, produce an axial component along carrying roller 10 and gear wheel 11, when this axial component overcomes the application force that wanders off of chain 9, the scraper plate 13 of a side just drops to motion on the carrying roller 10 on the chain 9, and chain 9 is just being walked again, get back to and do normal operation on the upper rail 7.Like this, this deviation correcting device just can be when chain 9 wanders off, and scraper plate 13 with under the situation that casing 4 contacts is not just realized correcting wandering off automatically.

The utility model is applicable on the chain-linked conveyer, in order to correct chain and scraper plate wandering off in backhaul.
