Background technology
Fork truck belongs to carrying class construction machinery and equipment, and carrying operation mainly realizes by door frame and pallet fork (or other all kinds of accessories) combined action of vehicle front.For convenient metering, to the goods of carrying, need to weigh its weight, because the cargo weight of carrying is large, and it comes in every shape, and it is weighed more difficult.
Existing mode of weighing to transporting goods is mainly divided into weighing separately weighs two kinds with vehicle-mounted:
Weigh separately and will first cargo transfer be weighed to the weighing instrument of appointed place exactly, and then be transported to destination.Although can guarantee weighing precision, its complex operation, consuming time, can greatly reduce the work efficiency of carrying.
Vehicle-mountedly weigh and be divided into that pallet fork sensor is weighed and signal detecting (pressure) conversion is weighed two kinds.The static weighing precision of pallet fork sensor weighting manner is higher, but dynamic weighing precision is poor, has affected equally carrying work efficiency; And exist mounting structure complicated, the shortcoming that routine inspection is difficult in maintenance.Signal detecting is converted weighting manner in addition, though it is succinct to have mounting structure, routine inspection is easy to maintenance, but the problem of dynamic weighing precision poor (>=± 5%) is not still solved at all.
The weighing precision of above-mentioned two kinds of vehicle-mounted weighting manners all can be subject in handling process the impact from the instant impact of all directions, and this is because when carrying fork truck goods, can make a series of actions such as pallet fork picking, door frame lifting and door frame introversion adjustment.Sensor is weighed and signal detecting is weighed all can door frame inclined angle variation and change; The simultaneously variation of goods shelf lifting velocity and the dynamic change that produces also can cause weighing data to occur deviation.
Utility model content
The utility model, in order to solve the problems of the technologies described above, provides a kind of fork truck that adopts two dynamic compensation weighing systems, when guaranteeing carrying fork truck work efficiency, has realized higher dynamic weighing precision (≤± 3%).
The technical solution of the utility model is: the fork truck of a kind of pair of dynamic compensation weighing system, comprise lift oil tank and goods shelf, described lift oil tank is connected with the pressure sensor for detection of its hydraulic fluid pressure, the mouth of described pressure sensor is electrically connected to the controller of being located at control capsule inside, and the mouth of described controller is electrically connected to the display instrument that is provided with control capsule outer face; On described goods shelf, be connected with the long angle transducer that plays motion with one, the mouth of described long angle transducer is connected with described controller.
Further, described long angle transducer comprises for detection of the angular transducer of forklift door frame leaning angle and linear transducer for detection of goods shelf lifting velocity.
Further, described controller comprises data processing module, and the input end of described data processing module is connected with pressure treatment module, dynamic compensation module respectively, and its mouth is connected with described display instrument; The input end of described pressure treatment module is connected with described pressure sensor; The input end of described dynamic compensation module is connected with inclination angle processing module, velocity process module respectively, and described inclination angle processing module, velocity process module are connected with described long angle transducer respectively.
When truck driver operation fork truck transports goods, take turns doing out a series of actions such as pallet fork picking, goods shelf lifting and door frame introversion adjustment.Now, be arranged on the pressure sensor on lift oil tank, can obtain an oil cylinder working-pressure analog signals changing according to cargo weight, this pressure signal is weighed after processing by controller, can obtain foundation weighing data.But because the pressure simulation amount signal of lift oil tank can, along with the angle variation of door frame leaning angle and the variation of goods shelf lifting velocity, change and produce dynamically.So carrying out corresponding two dynamic compensation, the foundation weighing data that the angle of the door frame leaning angle that the utility model detects by long angle transducer and the numerical value of goods shelf lifting velocity detect pressure sensor process, thereby obtain relatively accurate weighing data, finally send to that telltale instrument shows and store in real time, the precision of its dynamic weighing reaches≤and ± 3%.
The utility model is by detecting two multidate informations of door frame leaning angle and goods shelf lifting velocity, and according to the input of pressure sensor, carry out two dynamic compensations, can guarantee the efficiency of carrying fork truck work, can realize again higher dynamic weighing precision, reach≤± 3%.
