Description
Technical field
The utility model relates to a kind of weighing system, is specifically related to a kind of shovel loader intelligent weighing system, belongs to field of mechanical technique.
Background technology
Shovel loader, as the main machine of shovel dress bulk material and short-distance transport in harbour, mine and rail transportation system, carries the work of directly weighing effectively to control material transportation, transfer fast simultaneously.Existing shovel loader weighing system principle utilizes the working pressure of boom cylinder hydraulic system to fill the linear ratio relation of weight of material with shovel, by weight data collecting unit-pressure transducer, electric signal is inputed to CPU central control unit, draw the weight of material as calculated.
Because this weighing measurement is in the dynamic job of shovel loader all the time, be subject to scraper bowl propradation, the degree of jolting of road conditions and the impact of shovel loader travel speed, when not having material to load, the working pressure value signal of the oil cylinder hydraulic system brought that these factors are likely wrong is sent to CPU, namely there is the phenomenon of unloaded calculation amount in system, and the accuracy of measurement is low.
Summary of the invention
The utility model provides a kind of shovel loader intelligent weighing system, can improve the dynamic weighing accuracy of shovel loader.
For achieving the above object, this shovel loader intelligent weighing system, comprise CPU, pressure transducer a, pressure transducer b, LCDs, printer, power module and exterior storage and radio transmitting device, described pressure transducer a is arranged on boom cylinder oil-feed loop, pressure transducer b is arranged on boom cylinder oil return circuit, and the two is all connected with the input end of CPU; Described LCDs, printer are all connected with the output terminal of CPU with exterior storage and radio transmitting device; Described power module is responsible for providing instrument weighing system and printer electricity consumption; Also comprise two approximated positions sensor, described two approximated positions sensor is arranged on loading arm, and is connected with the input end of CPU.
Two approximated positions sensor, itself has the sensor of two receiving position signals, a lower position signal, a high position signal, and to condition debugging when initially installing that high position signal sends, the structure with swing arm is relevant with mounting means.
LCDs and operation keyboard thereof are all with bias light at night.
Compared with existing equipment, this device is by increasing two approximated positions sensor, realize the detection to swing arm duty during loading mechanical shovel dress material and judgement, namely only have when scraper bowl lift height meets or exceeds setting value, just start and go detected pressures value for the pressure transducer detecting hydraulic fluid pressure, then convert electric signal to and be sent to cpu central processing unit calculating weight of material, effectively prevent pretending of existing in prior art and carry, ensure that authentic and valid measurement and precision.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing;
Fig. 2 is utility model works schematic diagram.
In figure: 1, CPU, 2, two approximated positions sensor, 3, pressure transducer a, 4, pressure transducer b, 5, LCDs, 6, printer, 7, power module, 8, exterior storage and radio transmitting device.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As depicted in figs. 1 and 2, this shovel loader intelligent weighing system, comprise CPU1, pressure transducer a3, pressure transducer b4, LCDs 5, printer 6, power module 7 and exterior storage and radio transmitting device 8, described pressure transducer a3 is arranged on boom cylinder oil-feed loop, pressure transducer b4 is arranged on boom cylinder oil return circuit, and the two is all connected with the input end of CPU1; Described LCDs 5, printer 6 are all connected with the output terminal of CPU1 with exterior storage and radio transmitting device 8; Described power module 7 is responsible for providing instrument weighing system and printer 6 electricity consumption; Also comprise two approximated positions sensor 2, described two approximated positions sensor 2 is arranged on loading arm, and is connected with the input end of CPU1.
Two approximated positions sensor 2, itself there is the sensor of two receiving position signals, a lower position signal, a high position signal, when the condition that high position signal sends is debugged when initial installation, when scraper bowl does not have lifting, lower position signal produces electric signal and sends to central controller, when scraper bowl lifting meets or exceeds height (this altitude range is relevant with mounting means with the structure of swing arm) of setting, lower position signal is just for high position signal sends electric signal to central controller, that is to say, when first weighing system central controller receives lower position signal, then after receiving high position signal, just start to weigh, in case the misnomer weight that stopper arms does not have lifting or lift height to cause not.
LCDs 5 and operation keyboard thereof all with bias light at night, be convenient to light dark time operation, operate shovel loader personnel by keyboard to operator scheme, weighing results, accumulation result, and weigh number of times and information carry out inquiring about and arranging simultaneously.
In the course of work of shovel dress material, two proximity position transducer 2 pairs of swing arm duties detect and judge, after reaching certain height, activation pressure sensor a3, pressure transducer b4 are responsible for carrying out signals collecting and conversion to the pressure data of boom cylinder, the weight carried when promoting swing arm by CPU 1 analytical calculation, thus avoid the unloaded calculation amount of system.
Controlled by CPU1 in house software, analyzing and processing is carried out to the change of loading machine movable arm cylinder pressure under speed or bad road conditions, intelligent compensation, thus draw accurate weight data, in this way, shovel loader just can record weight of material under motion state, and in uninstall process, does not also have an impact to the activity of swing arm.
