Abstract
The utility model relates to a novel dynamic reactive grab bucket scale characterized in that a weighing sensor is installed in an inclined manner, that the inclined angle [alpha] of the weighing sensor is from 30 to 45 degrees, and that an angle positioner is arranged under an movable arm and is composed of a support and two positional sensors. The novel dynamic reactive grab bucket scale is simple in manipulation and high in weighing precision.
Description
Technical field
The utility model relates to a kind of automatic Weighing technical field, relates in particular to a kind of novel dynamic reactive grab bucket scale.
Background technology
Idle grab bucket, it is a kind of loading mechanization extremely widely that uses, particularly port and pier, bulkload place, and along with modern management is gradually improved and the popularization of compulsory measure is transported in strict overload etc. safely, limit for tonnage needs metering, cost management metering is the important means of enterprise cost management, terminal charges clearing need metering etc., in the urgent need to a kind of high precision, the idle grab bucket scale of high automation, though and at present domesticly have few enterprise in small lot batch production, its precision is generally all between 3～5%FS, the installation method of LOAD CELLS exists defect and swing arm angle to change uncompensated function and causes, cause idle grab bucket scale metering outfit to exist general precision low and cannot meet measuring requirement, and then affect its propagation and employment.
Utility model content
The utility model, for the imperfection of existing weighing technology, provides a kind of novel dynamic reactive grab bucket scale.
The technical solution adopted in the utility model is:
A kind of novel dynamic reactive grab bucket scale, comprise LOAD CELLS, bearing wheels, swing arm, grab bucket, wire rope, described swing arm upper end is provided with bearing wheels, the wheel shaft below of described bearing wheels is provided with LOAD CELLS, described wire rope is walked around bearing wheels and is connected with grab bucket, it is characterized in that: described LOAD CELLS is to tilt to install, its inclined angle alpha is 30 ° to 45 °, described swing arm below is provided with angle locater, described angle locater is made up of support and two position transducers, one of them position transducer is rack-mount, another position transducer is arranged on swing arm.
The beneficial effects of the utility model are:
The utility model has improved deficiency of the prior art, coordinate with angle locater by LOAD CELLS, in the time of idle grab bucket operation, the weighing data of corresponding proportion compensation weighing sensor pressed the variation of angle by position transducer, obtain more accurately weighing data, be better than ± 1%FS of measuring accuracy, it is convenient that this structure is installed, simple to operate, Weighing automatically completes.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1---LOAD CELLS, 2---bearing wheels, 3---support, 4---position transducer, 5---swing arm, 6---grab bucket, 7---wire rope.
Embodiment
Below in conjunction with accompanying drawing, embodiment is illustrated.
As shown in Figure 1, a kind of novel dynamic reactive grab bucket scale, comprise LOAD CELLS 1, bearing wheels 2, support 3, position transducer 4, swing arm 5, grab bucket 6, wire rope 7, described bearing wheels 2 belows tilt to be provided with LOAD CELLS 1, its inclined angle alpha is 30 ° to 45 °, and this mounting means makes being subject to force direction and weighing degree of accuracy the best of LOAD CELLS 1.Grab bucket 6 contained materials by wire rope 7 in the stressed LOAD CELLS 1 that is transmitted to bearing wheels 2 belows, obtain certain data-signal, in operation process, wire rope 7 and swing arm 5 must need to rise according to operation, in swing arm 5 lower ends, angle locater is installed, described angle locater is made up of support 3 and two position transducers 4, and one of them position transducer is rack-mount, and another position transducer is arranged on swing arm.In the time that swing arm 5 rises or declines, can accurately measure by two position transducers 4 angle that swing arm rotates, now instrument can be carried out data operation and intelligent processing method by the signal obtaining on position transducer 4, and the numerical value that LOAD CELLS 1 is measured compensates and corrects, show that accurate metering result sends demonstration.
