Detailed description of the invention
The exemplary embodiments that embodies feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various variations on different embodiment, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing be when the use that explain in itself, but not in order to limit the present invention.
The long-range meausring apparatus of the embodiment of the present invention can be used in the hoisting crane of the embodiment of the present invention, is applicable in all hoisting cranes that need accurate weighing weight quality, or is applicable to dolly narrow space, cannot installs in the hoisting crane of weighting apparatus.
The hoisting crane of the embodiment of the present invention, has the long-range meausring apparatus of the embodiment of the present invention.
As shown in Figure 1, the hoisting crane of the embodiment of the present invention and remote weighing device of the present invention further illustrate as follows, and the remote weighing device of the embodiment of the present invention comprises and weighs end (or claiming meausring apparatus body) 7 and signal receiving end 6.
Wherein, weigh end 7 and be arranged on the suspender 12 of hoisting crane 1 of the embodiment of the present invention, hoisting crane 1 can be conventional hoisting crane, comprises dolly 11, suspender 12, driver's cab 13 etc., also comprises mechanism and structure that other is necessary.
Weigh end 7 and comprise battery 2, projector 3, treater 4 and LOAD CELLS 5.And signal receiving end has receptor 6 etc., signal receiving end is arranged on 13 li of the driver's cabs of hoisting crane 1 or is arranged in the electrical control cubicles of hoisting crane 1.
Wherein, battery 2 provides electric energy for projector 3, treater 4 and LOAD CELLS 5; But the present invention, not as limit, also can be powered to projector 3, treater 4, LOAD CELLS 5 by the power supply of other types.
LOAD CELLS 5 is arranged on suspender 12, can measure the quality of weight 8.Concrete, be for example arranged under suspender axle and bear pressure, or be arranged on bearing tension on suspender side plate.Suspender axle wherein, is the framing member of suspender and the adapter shaft of pulley, and therefore, selection pressure sensor, as LOAD CELLS 5, is arranged under suspender axle, can detect the pressure variation that suspender axle bears; Equally, the side plate of framing member can afford the pulling force of weight 8, therefore, selects pulling force sensor as LOAD CELLS 5, is arranged on described side plate, can detect the tension variations that side plate bears.To sum up, in these cases, LOAD CELLS 5 all can directly be measured the quality of the weight of slinging 8 on suspension hook, and with the variation of this quality, change in electric occurs.
Treater 4 is mainly to receive the electric signal measured of LOAD CELLS 5, and is defeated by projector 3 after treated, conversion, coding; Projector 3 is mainly that the electric signal that treater 4 is imported into is launched with the form of transmission over radio; So that the receptor 6 of signal receiving end can receive wireless signal, and offer crane control system after decoding deciphering.Like this, crane control system can obtain according to the data of LOAD CELLS 5 quality of 12 times lifted weights 8 of suspender, and judge whether hoisting crane 1 overloads, underload, to take in time corresponding measure.Above-mentioned weighing data also can be for production scheduling, record.
The long-range meausring apparatus of the embodiment of the present invention, wherein battery 2, treater 4, projector 3 can fit together, and are also that suspender 12 sides are assembled and be arranged on to one, are mounted in specifically on the side plate of framing member of suspender 12.
Meanwhile, treater 4 can have battery electric quantity detecting unit, in the time of the electric weight deficiency of battery 2, treater 4 can detect this phenomenon, and through projector 3, electric weight is detected to delivering, and after receiving, receptor 6 is transferred to crane control system, and can remind operating personal to change in time battery 2.If battery 2 is chargeable batteries, need to charge to battery 2 in time.
The long-range meausring apparatus of the embodiment of the present invention, the receptor 6 of signal receiving end receives the radio wave signal (can be also other wireless signal) that projector 3 is launched, and offers operating personal or crane control system after decoding is processed.Like this, LOAD CELLS 5 Direct Measurement of Heavy thing 8 quality, survey precision is high, the power supply of LOAD CELLS 5 is powered by battery 2, and the signal of measurement is sent by projector 3, and receptor 6 receives, do not have cable to be connected between suspender 12 and monkey 11, realized long-range accurate measurement.
Technical scheme of the present invention is disclosed as above by preferred embodiment.Those skilled in the art should recognize change and the retouching the scope and spirit of the present invention that the appended claim of the present invention discloses, done in the case of not departing from, within all belonging to the protection domain of claim of the present invention.
