Description
Technical field
The utility model relates to novel automatic calibration device for hopper scale.
Background technology
Continuous lifting along with metallurgical automation degree, hopper electronic scale (hereinafter to be referred as bunker scale) automatic, quick, metering to bulk materials is used widely, for guaranteeing the weighing accuracy of bunker scale, regularly by standard weights, to bunker scale, calibration is very important.In general, the calibration of bunker scale is that the counterweight of standard quality is loaded on the sensor of bunker scale by bunker scale scale body, and the demonstration weight of the sensor output signal that makes bunker scale on weighting display instrument is identical with loaded standard weights.
When bunker scale is carried out to verification, for the larger weighing device of measurement range, during verification, need a large amount of counterweights, moving into take out of needs a large amount of manpower and materials, and duration for verification, efficiency are low, need of work repetitive operation, in operating process, security is not high yet.
Utility model content
The purpose of this utility model is to provide a kind of novel automatic calibration device for hopper scale, and it can carry out verification accurately and quickly to bunker scale.
For achieving the above object, the technical solution of the utility model is a kind of novel automatic calibration device for hopper scale of design, comprises back up pad, bracing frame, dolly, hopper, LOAD CELLS and framework; Back up pad below is fixed with two vertical supports, and two supports are fixed with respectively vertical slide rail, are respectively arranged with slide block on slide rail; LOAD CELLS is between hopper and framework; Directly over hopper, be provided with the first shelf of horizontal, directly over the first shelf, be provided with the second shelf of horizontal, the first shelf is connected by spring with the second shelf, between the first shelf and the second shelf, is provided with some pressure transducers, and the second shelf two ends are separately fixed on slide block; Each slide block is furnished with respectively its jacking gear moving up and down of driving, and jacking gear is fixed in back up pad; Back up pad is fixed on bracing frame, and bracing frame is fixed on dolly.
Preferably, described pressure transducer is uniform on the first shelf.
Preferably, described LOAD CELLS is circumferentially uniform along hopper.
Advantage of the present utility model and beneficial effect are: a kind of novel automatic calibration device for hopper scale is provided, and it can carry out verification accurately and quickly to bunker scale.
During work, jacking gear makes the first shelf drop to contact hopper upper surface, continues to decline, and makes the second shelf apply downward pressure, and the pressure transducer arranging between the first shelf and the second shelf can detect this pressure.
Adopt the pressure of the second shelf to replace the weight of standard test weight to carry out verification, not only convenient but also quick, operating personnel can make the second shelf pressurization or release according to field condition, calibration operation are more simplified also time saving and energy saving.
Also there is good application prospect the aspects such as automatic calibration device for hopper scale of the present utility model claims at platform, the daily inspection of truck scale and track scale, fault distinguishing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
The concrete technical scheme of implementing of the utility model is:
As shown in Figure 1, a kind of novel automatic calibration device for hopper scale, comprises back up pad 1, bracing frame 2, dolly 3, hopper 4, LOAD CELLS 5 and framework 6; Back up pad 1 below is fixed with 7, two supports 7 of two vertical supports and is fixed with respectively vertical slide rail 8, is respectively arranged with slide block 9 on slide rail 8; LOAD CELLS 5 is between hopper 4 and framework 6; Directly over hopper 4, be provided with the first shelf 10 of horizontal, directly over the first shelf 10, be provided with the second shelf 11 of horizontal, the first shelf 10 is connected by spring 12 with the second shelf 11, the first shelf 10 and 11 of the second shelves are provided with some pressure transducers 13, the second shelf 11 two ends and are separately fixed on slide block 9; Each slide block 9 is furnished with respectively its jacking gear moving up and down 14 of driving, and jacking gear 14 is fixed in back up pad 1; Back up pad 1 is fixed on bracing frame 2, and bracing frame 2 is fixed on dolly 3.
Described pressure transducer 13 is uniform on the first shelf 10.
Described LOAD CELLS 5 is circumferentially uniform along hopper 4.
During work, jacking gear 14 makes the first shelf 10 drop to contact hopper 4 upper surfaces, continues to decline, and makes the second shelf 11 apply downward pressure, and the pressure transducer 13 of the first shelf 10 and 11 settings of the second shelf can detect this pressure.
Adopt the pressure of the second shelf 11 to replace the weight of standard test weight to carry out verification, not only convenient but also quick, operating personnel can make the second shelf 11 pressurization or releases according to field condition, calibration operation are more simplified also time saving and energy saving.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
