Description
Technical field
The utility model relates to a kind of concrete matched materials device, specifically the quick scale correcting apparatus of a kind of concrete batching scale.
Background technology
Concrete refers to makes Binder Materials with cement, and sand, masonry gather materials; Coordinate by a certain percentage with water, the building materials obtained through stirring, wherein need to use dosing device, and conventional in dosing device be concrete batching scale, concrete batching scale is formed primarily of hopper, base and the LOAD CELLS be arranged between hopper and base.
Concrete batching scale needs periodic calibration, to ensure the accuracy of weighing data, and then ensures concrete product quality.The debugging of current concrete batching scale is divided into dynamic batching error-detecting and static weighing to calibrate two parts, wherein, dynamic batching error is then check feed proportioning system in process of production to the working control ability of material flows amount and stability, to have special device and carry out; And the school scale that static weighing calibration is namely said usually, mainly in order to check and calibrate the accuracy of measuring of burden balance self, usually adopt counterweight to calibrate at present.School scale is commonly referred to for static weighing calibration, the school scale frequency monthly 1 time, concrete batching weighing journey reaches 6 ~ 8t, require that calibrator quantity is at least 50% of range ability, each school scale all want artificial the counterweight of several tons of weights is transported to treat school scale hopper on, carry out counterweight gross weight and system displayed value to contrast the weighing accuracy judging concrete batching scale.
The mode of counterweight school scale is only applicable to the scale of small-range usually, be directed to the burden balance of relatively large journey, need the counterweight of a dead lift several tons of weights extremely to require great effort, and counterweight placement location incorrect or carelessness when manually checking counterweight weight also can cause school scale error; In addition counterweight pole handling process very easily causes and collides with and cause the error of actual mass and standard configuration quality, and counterweight also can bring comparatively big error because maintaining the improper long-time corrosion caused.
Utility model content
The purpose of this utility model is to provide a kind of efficiency high, laborsaving and the quick scale correcting apparatus of concrete batching scale that error is little.
To achieve these goals, the utility model provides a kind of concrete batching scale quick scale correcting apparatus, include symmetry be arranged on hopper both sides ground crab-bolt, be arranged on bending resistance bar above hopper, connect the rope of bending resistance bar and ground crab-bolt and to be arranged in the middle part of bending resistance bar and to withstand on the jacking apparatus of hopper central, wherein, between described jacking apparatus and hopper, pressure transducer is installed, described earth anchor ties the normal of line through hopper center of gravity, and the projection of described bending resistance bar covers two ground crab-bolts.
The scale correcting apparatus of technical solutions of the utility model is adopted to have following features: due to jacking apparatus, bending resistance bar, rope and ground crab-bolt combination, the power of jacking is passed to the earth, and the reacting force that jacking produces hopper is as the power required for calibration, detected the size of top lift by the pressure transducer of calibration, the reading of the burden balance of comparison simultaneously can be calibrated.Compared to traditional counterweight, the pressure that the adjustment burden balance that jacking apparatus can be more convenient as required need, efficiency is higher also more laborsaving, it also avoid because counting or counterweight damage the error caused after replacing counterweight, therefore more practical.
Preferably, be provided with one bottom ground crab-bolt through the bending resistance beams of metal below burden balance base, the pressure that a part of pull transfer that ground crab-bolt can be subject to by such design is subject to burden balance and burden balance balances each other, and invariably crab-bolt is pulled out.
Preferably, described jacking apparatus is hydraulic jack, and the volume of hydraulic jack is little, and uses more laborsaving.
Preferably, described bending resistance bar is joist steel, and its end is provided with the projection or groove that prevent rope from deviating from, and such arranging can ensure that the intensity of bending resistance bar reduces costs simultaneously, and use safety, rope can not be there is in use and deviate from.
Preferably, be provided with the cushion block increasing hopper lifting surface area between described pressure transducer and hopper, such design can avoid hopper, because stress point is less, local damage occurs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, hopper 1, ground crab-bolt 2, base 3, bending resistance bar 4, projection 5, hydraulic jack 6, pressure transducer 7, cushion block 8, rope 9, LOAD CELLS 10.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, the utility model provides a kind of concrete batching scale quick scale correcting apparatus, comprise symmetry and be arranged on ground ground, hopper 1 both sides crab-bolt 2, for ensureing the intensity of ground crab-bolt 2, avoid it to be drawn out, the bottom of ground crab-bolt 2 is provided with one through the bending resistance beams of metal below burden balance base 3, select joist steel as bending resistance beams of metal herein, a bending resistance bar 4 is laid above hopper 1, bending resistance bar 4 also adopts joist steel, reduce costs with proof strength simultaneously, above the end of joist steel, weld a projection 5 simultaneously, inside projection 5, arrange rope 9 is connected in ground crab-bolt 2, and ensure that bending resistance bar 4 is by maintenance level during jacking, below the middle part of bending resistance bar 4, hydraulic jack 6 is set, the below arranging hydraulic jack 6 sets gradually pressure transducer 7 and cushion block 8, need during installation to ensure lifting jack 6, the axis that pressure transducer 7 and cushion block 8 are formed through hopper self with the center of LOAD CELLS 10, need to ensure that pressure transducer 7 is that calibrated or new simultaneously, and in order to ensure the convenient and practical property of cushion block 8, the wooden unit of preferably taper herein, and ensure that wooden unit covers the base area of hopper 1 as far as possible.
The Main Function of rope 9 transmits pulling force, and wire rope or pull bar can be selected herein also passable.
The scale correcting apparatus of technical solutions of the utility model is work like this: hydraulic jack 6 is jacking bending resistance bar 4 downward squeeze pressure sensor 7 simultaneously upwards, form a pair reacting force, the power of jacking is passed to by rope 9 and ground crab-bolt 2 by bending resistance bar 4, rope 9 is transmitted next pull transfer to the bending resistance beams of metal of joist steel by ground crab-bolt 2, and the pressure that pressure transducer 7 passes over passes to hopper 1 uniformly by cushion block 8, thus the gravity that the counterweight that simulation is evenly placed produces, pressure is delivered himself LOAD CELLS 10 and produces reading by hopper 1, pressure is passed to base 3 by LOAD CELLS 10, and the joist steel finally passed to below base 3, the pressure passing to joist steel with rope balances each other.By the pressure transducer 7 of Comparison calibration and the reading of LOAD CELLS 10, thus draw error.
Above-described is only preferred implementation of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
