The beneficial effects of the utility model are that: utilize gear drive, more the every single move angle of direct more accurate measuring scraper blade arm, rational utilization gear drive compares, amplifies the every single move angle of scraper blade arm, makes to detect the precision improvement to the accurate control every single move angle of accessible PLC when getting the material.
Description
Technical field
The utility model is related to a kind of scraper reclaimer pitching angle detection device.
Background technology
At present, with the development of Bulk material industry, side formula scraper reclaimer is used as one of traditional bulk material conveying machinery, property
Can constantly be lifted, control system is more and more intelligent, its function is more and more diversified.Side formula scraper reclaimer needs to read in real time
The angle of scraper arm, and rotary encoder is set generally on cable drum remembering the folding and unfolding length of steel wire rope.It is logical
Cross the folding and unfolding length of control steel wire rope to control the luffing angle of scraper arm, so as to control feeding depth of the scraper arm to stockpile,
The size of feeding amount is controlled.Because steel wire rope has certain elasticity, length has certain elongation, work during use
Error can be gradually produced in work so that the luffing angle control of scraper arm is inaccurate, therefore it is entered using after a period of time
Row adjustment.
Utility model content
For weak point present in the problems referred to above, the utility model provides a kind of scraper reclaimer luffing angle
Detection means, eliminates impact of the steel wire rope elasticity to scraper arm luffing angle testing result, more accurately controls luffing angle, reaches
To work requirements.
For achieving the above object, the utility model provides a kind of scraper reclaimer pitching angle detection device, including：
Bull gear, it is arranged on the sprocket shaft of scraper arm；
Anglec of rotation encoder, it is arranged in frame, and the frame is hinged with described scraper arm one end, the scraper arm
The other end is connected with jacking system；
Little gear, it is arranged in the rotating shaft of the anglec of rotation encoder, and the little gear is engaged with the bull gear；
During the scraper arm pitching, the bull gear is center of circle rotation around the sprocket shaft of the scraper arm, is driven described little
Gear rotates.
Further improve as the utility model, the little gear is 1 with the gear ratio of the bull gear:10.
Further improve as the utility model, the anglec of rotation encoder is connected with PLC, receive the control of the PLC
System instruction, and control the jacking system.
The beneficial effects of the utility model are：
1st, gear drive is utilized, more directly can more accurately detects the luffing angle of scraper arm, it is no longer necessary to periodically to inspection
Examining system is corrected；
2nd, gear ratio is rationally utilized, the luffing angle of scraper arm is amplified, improve accuracy of detection, and taken
Luffing angle can accurately be controlled by PLC during material；
3rd, structure is simpler, convenient to overhaul and safeguard；
4th, manufacturing cost is not high, easily promotes.
Description of the drawings
Fig. 1 is a kind of structural representation of scraper reclaimer pitching angle detection device of the utility model.
In figure：
1st, scraper arm；2nd, bull gear；3rd, frame；4th, anglec of rotation encoder；5th, little gear.
Specific embodiment
As shown in figure 1, a kind of scraper reclaimer pitching angle detection device of the utility model embodiment, including scraping
Plate arm 1, bull gear 2, frame 3, anglec of rotation encoder 4 and little gear 5.Bull gear 2 is arranged on the sprocket shaft of scraper arm 1.
Anglec of rotation encoder 4 is arranged in frame 3, and frame 3 is hinged with the one end of scraper arm 1, and the other end of scraper arm 1 connects with jacking system
Connect.Little gear 5 is arranged in the rotating shaft of anglec of rotation encoder 4, and little gear 5 is engaged with bull gear 2.During 1 pitching of scraper arm, greatly
Gear ring is center of circle rotation around the sprocket shaft of scraper arm 1, drives little gear 5 to rotate.Anglec of rotation encoder 4 is connected with PLC, receives
The control instruction of PLC, and control jacking system.
During concrete installation, the bull gear 2 of an incomplete appropriate angle is installed first on the sprocket shaft of scraper arm 1,
Because the pitching of scraper arm 1 has scope, so can be more cost-effective than installing whole bull gear 2.Then pacify in frame
Gyration encoder 4 is reinstalled, a little gear 5 is installed in the rotary shaft of angle of revolution encoder 4 and is engaged with bull gear 2.
When 1 pitching of scraper arm, bull gear 2 is center of circle rotation around sprocket shaft, drives little gear 5 to rotate.Wherein, little gear
5 is 1 with the gear ratio of bull gear 2:10, therefore the angle of luffing range of cantilever support can amplify 10 times.The detection means no longer needs to pass through
The luffing angle of steel wire rope indirect detection scraper arm 1, but directly by the angle of revolution of detection little gear 5, and using big
Amplifying the angle of revolution, the final luffing angle for determining scraper arm 1 so can be more accurate for the gearratio of gear ring and little gear
Reading scraper arm 1 angle.
Meanwhile, luffing angle is accurately controlled by PLC during feeding, PLC assigns control instruction to rotary encoder 4, revolution
Encoder 4 regulates and controls again jacking system, when the luffing angle that rotary encoder 4 detects scraper arm 1 reaches requirement, gives lifting system
System is assigned and ceased and desisted order, and finally realizes the control accurate to the luffing angle of scraper arm 1.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
