Description
Technical field
The utility model relates to a kind of aerial platform anticollision safety control, especially relates to a kind of aerial platform anticollision safety control based on load variations.
Background technology
Aerial platform is widely used in industries such as boats and ships, building, fire-fighting as an important branch of engineering machinery field, and it has vast potential for future development as new industry.
In recent years, hall's finishing, maintenance etc. are carried out in indoor, the interior operation of factory building that increasing aerial platform is applied to.Because existing aerial platform lacks the anticollision safety control system, when the staff operates the aerial platform platform,, attention do not concentrate if having slightly; Or have only one or two people; In the time of can't carrying out comprehensive observation simultaneously, very easily cause work basket and working arm and other obstacle to bump, accident frequency is high; Functional reliability is low, and efficient is poor.In addition, not good enough because of operator's operating skill, or there are other situation such as fault because of apparatus control system, also tend to make aerial platform to run into obstacle, cause casualties or economic loss.And, in the prior art,, need the extra sensor of setting up in order to control the dynamics of collision.Generally speaking; Sensor is located on the positions such as aerial platform work bucket, working arm or hydraulic reservoir; Like anticollision design based on the hypracoustic aerial platform; Because the data of ultrasonic transduter gained are the range informations between super sonic and the obstacle, there is bigger uncertainty in the information, reliability is still lower.
The utility model content
For overcoming the above-mentioned defective that prior art exists, the utility model provides a kind of reliable operation, and efficient is high, the aerial platform anticollision safety control based on load variations of effectively minimizing accident occurrence frequency.
The technical scheme of the utility model is: a kind of aerial platform anticollision safety control based on load variations; Comprise Hydraulic Pump, change-over valve, microcomputer, hydraulic pressure transducer I, hydraulic pressure transducer II; Said Hydraulic Pump is connected with change-over valve, and said change-over valve is connected with actuating unit through in-line, and actuating unit is connected with change-over valve through oil return line; Hydraulic pressure transducer I one end is connected with actuating unit; The other end is connected with microcomputer, and hydraulic pressure transducer II one end is connected with actuating unit, and the other end is connected with microcomputer.
Said change-over valve is three two logical change-over valves.
Said actuating unit can be shovel mechanism, swing type mechanism, traveling gear or ejector dozer mechanism etc.
The Hydraulic Pump below also is provided with filtering net, and filtering net is located at the hydraulic reservoir top, and filtering net one end stretches in the hydraulic oil of hydraulic reservoir through oil circuit.Change-over valve also stretches in the hydraulic oil of hydraulic reservoir through oil circuit.
The main theoretical basis of the reform of Chinese economic structure of the utility model is:
(1) when actuating unit and obstacle collided, the operation pressure of actuating unit can rise, and this moment, the actuating unit oil cylinder working-pressure rose; In luffing lifting process, when mechanism such as the arm that sets out and obstacle collided, cylinder under the amplitude oil cylinder (rodless cavity) pressure will rise;
Is how many amplitudes just can be regarded as when (2) pressure rises to that mechanism and obstacle bump against? The utility model takes to note the force value of actuating unit when not bumping (also promptly activating the anticollision function); Be worth as detection reference Pb with this; On this benchmark, be multiplied by an anticollision COEFFICIENT K c (this coefficient value 1.2 ~ 1.8) then, then goal pressure Ptarget=Pb * Kc; Through the operation pressure of real-time detection actuating unit, during collision, the actuating unit oil cylinder working-pressure rises, if when detecting the operation pressure Pc of actuating unit >=goal pressure Ptarget, thinks collision phenomenon has taken place.
The aerial platform anticollision safety control principle of work based on load variations of the utility model is:
Detect the operation pressure Pc of actuating unit in real time; This operation pressure Pc detects through the hydraulic pressure transducer induction of being located in the actuating unit oil cylinder; When if operation pressure Pc is worth less than goal pressure Ptarget (Ptarget=Pb * Kc), then judge the phenomenon that do not bump; Actuating unit continues normal operation.
When actuating unit and obstacle collided, the operation pressure of actuating unit rose, if the operation pressure Pc that detects actuating unit more than or equal to goal pressure Ptarget (Ptarget=Pb * Kc), then judges collision phenomenon had taken place.
Processing after bumping: stop aerial platform work automatically.
After the utility model is installed and used in aerial platform; Can be under the situation that does not increase additional sensors; Effectively control the dynamics of collision, independently detect whether trouble free service of aerial platform, when running into dangerous situations such as collision, can quit work timely and effectively; Minimizing is to staff's the injury and the loss of article, and reduction flight-line maintenance cost of upkeep.
The utility model is simple in structure, and functional reliability is high.
