Abstract
This utility model provides a hopper scale calibrating device, comprising a hopper the bottom of which is connected to a weighing sensor. The weighing sensor is fixed on a strength bearing beam of the weighing sensor; two sides of the hopper is provided with a door-shaped fixing frame which is fixed on the ground; the door-shaped fixing frame and the door-shaped support frame consists of beams and stand columns; a standard sensor is fixed on the bottom of the beam of the door-shaped fixing frame; a jack is arranged on the top of the beam of the door-shaped support frame; and the mandrill of the jack is connected to the standard sensor. The hopper scale calibrating device saves time and labor; a great quantity of weights are not required to be manually carried during the whole calibration process; the calibration efficiency is high, which saves the calibration times, improves production efficiency, greatly improves the safety guarantee of the operation personnel and reduces the occupational health hazard.
Description
Technical field
The utility model belongs to measurement and calibration technical field, relates to a kind of bunker scale calibrating installation.
Background technology
At smelter, have a large amount of hoppers to claim for weighing material, its bunker scale range does not have 4t, 8t, 20t, 30t not etc.According to domestic and international calibrating operation of the same type, see, the calibration of bunker scale at present adopts the method for calibration of weight mostly.Due to the requirement of equipment precision, each calibration needs carrying and loads and unloads the counterweight of a large amount of Different Weight.To calibrate the hopper of a 8t, be called example, on average need the counterweight of a dead lift and unloading 20kg to add up 800 times, need to drop into operating personnel 15 people, accumulative total workload is large, activity duration is long, and have the potential safety hazard injured by a crashing object by counterweight, and operating environment badly belongs to high temperature with high dust region, brought harm to operating personnel's health.
Utility model content
The purpose of this utility model is the problem existing for prior art, and a kind of time saving and energy saving and safe bunker scale calibrating installation is provided.
For this reason, the utility model adopts following technical scheme:
A kind of bunker scale calibrating installation, comprise hopper, the bottom of described hopper is connected with LOAD CELLS, described LOAD CELLS is fixed on LOAD CELLS bearing beam, the both sides of described hopper are provided with the door type fixed mount fixing with ground, the bottom of hopper is connected with the door shape bracing frame of handstand, described door shape fixed mount and door shape bracing frame form by crossbeam and column, the bottom of described door shape fixed mount crossbeam is fixed with standard transducer, the top of described door shape bracing frame crossbeam is fixed with lifting jack, and the push rod of described lifting jack is connected with standard transducer.
The beneficial effects of the utility model are: time saving and energy saving, whole calibration process does not need a large amount of counterweight of a dead lift, only needs 3 people just can calibrate for error; Calibration efficiency is high, has saved the alignment time, has improved production efficiency; This device, for numeral demonstration, is eliminated the error effect that artificial reading brings, and greatly improves operating personnel's safety guarantee simultaneously, has reduced occupational health harm.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is structure side view of the present utility model.
In figure, 1-hopper, 2-door shape fixed mount, 201-fixed mount crossbeam, 202 fixed mount columns, 3-door shape bracing frame, 301-bracing frame crossbeam, 302-bracing frame column, 4-standard transducer, 5-lifting jack, 6-LOAD CELLS, 7-LOAD CELLS bearing beam.
Embodiment
As illustrated in fig. 1 and 2, a kind of bunker scale calibrating installation, comprise hopper 1, the bottom of hopper 1 is provided with LOAD CELLS 6, LOAD CELLS 6 is fixed on LOAD CELLS bearing beam 7, the both sides of hopper 1 are provided with the door type fixed mount 2 fixing with ground, the bottom of hopper 1 is connected with the door shape bracing frame 3 of handstand, door shape fixed mount 2 consists of fixed mount crossbeam 201 and fixed mount column 202, door shape bracing frame 3 consists of bracing frame crossbeam 301 and bracing frame column 302, the bottom of fixed mount crossbeam 201 is fixed with standard transducer 4, the top of bracing frame crossbeam 301 is fixed with lifting jack 5, the push rod of lifting jack 5 is connected with standard transducer 4.
Utilize the process of the utility model calibration bunker scale as follows:
1, before using, first standard transducer 4 and supporting weighing instrument are calibrated on force measuring machine (or counterweight);
2, standard transducer 4 is installed on to fixed mount crossbeam 201 bottoms, makes very heavy item 5, standard transducer 4 and LOAD CELLS 6 threes' central axes;
3, by supporting weighing instrument, finely tune each lifting jack 5, make each point be subject to some power and each point stress balance;
4, operation bunker scale weighing instrument, makes instrument be shown as zero;
5, according to calibration, should add weight, the push rod of controlling lifting jack 5 upwards ejects, and to standard transducer 4, applies the power making progress, and lifting jack 5 applies the large I of power and shown by the supporting weighing instrument being connected with standard transducer 4; According to acting force and reacting force principle, standard transducer 4 applies a downward big or small power such as grade by lifting jack 5 to door shape bracing frame 3, thereby LOAD CELLS 6 is applied to a downward big or small power such as grade, and LOAD CELLS 6 is stressed can be shown by bunker scale weighing instrument.Contrast supporting weighing instrument and hopper weighing instrument and show gravimetric value, to bunker scale weighing instrument, carry out quickly calibrated.
