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 raw material weigher.
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 in dosing device outbalance be concrete raw material weigher, concrete raw material weigher is formed primarily of hopper, base and the LOAD CELLS be arranged between hopper and base, concrete raw material weigher needs periodic verification or calibration, only has the accuracy of periodic verification or calibration guarantee weighing data, ensures concrete product quality.
The debugging of current concrete raw material weigher 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 static weighing calibration is to check the accuracy of measuring with calibration measurement scale self, counterweight is usually adopted to calibrate at present.School scale is commonly referred to for static weighing calibration, the school scale frequency monthly 1 time, concrete raw material weigher range is greatly to 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 starting material scale.Counterweight due to a dead lift several tons of weights easily causes colliding with of counterweight and causes the error of actual mass and standard configuration quality, counterweight placement location incorrect and carelessness when manually checking counterweight weight also can cause school scale error, whole process very complicated, time and effort consuming, school scale inefficiency; In addition counterweight also can bring comparatively big error because maintaining the improper long-time corrosion caused, and the scale correcting apparatus of concrete raw material weigher traditional is as seen badly in need of improving.
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 raw material weigher that error is little.
To achieve these goals, the utility model provides a kind of concrete raw material weigher quick scale correcting apparatus, include be symmetrically distributed in weigher LOAD CELLS both sides lower connecting device, be arranged on hopper both sides and the upper coupling arrangement up and down corresponding with lower connecting device and connect the stretching force detecting apparatus of upper and lower coupling arrangement, wherein go up coupling arrangement to comprise one through weigher LOAD CELLS central axis and ride over the cross bar on edge on hopper, and be positioned at cross bar two ends and be upward through the U-loop of cross bar, the end of described U-loop is provided with setting nut.
The scale correcting apparatus of technical solutions of the utility model is adopted to have following features: replace traditional counterweight owing to have employed stretching force detecting apparatus, its volume and weight significantly reduces, and uses more laborsaving; Stretching force detecting apparatus can ensure before use to be new or to have calibrated, thus ensures precision, and counterweight is due to volume, is inconvenient to calibrate; Scale correcting apparatus integrated model is comparatively simple, and mainly contain interconnective lower connecting device, stretching force detecting apparatus and lower connecting device composition, connect easy to use, efficiency is higher.
Preferably, described lower connecting device is the draw ring being fixed on weigher base or ground, and such design makes lower connecting device structure simpler, and cost is cheaper.
Preferably, described stretching force detecting apparatus is the spring balance or pulling force sensor that correct, and such stretching force detecting apparatus volume is little, and use cost is lower, and convenient operation.
Preferably, the two ends of described cross bar are provided with U-lag, and the setting nut on described U-loop is connected on U-lag, and U-loop can be made like this to adjust along cross bar direction, with the lower connecting device of the different weigher of correspondence, improve the utilization factor of scale correcting apparatus.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Wherein, LOAD CELLS 1, hopper 2, spring balance 3, cross bar 4, U-loop 5, metal draw ring 6, weigher base 7.
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 raw material weigher quick scale correcting apparatus, include the lower connecting device being symmetrically distributed in weigher LOAD CELLS 1 both sides, be arranged on hopper 2 both sides and the upper coupling arrangement up and down corresponding with lower connecting device and connect the stretching force detecting apparatus of upper and lower coupling arrangement, in order to reduce costs and improve the dirigibility operated, the preferred spring balance of stretching force detecting apparatus or pulling force sensor, use the spring balance 3 after correcting herein; Upper coupling arrangement comprises one and passes weigher LOAD CELLS 1 central axis and the cross bar 4 riding over edge on hopper 2, the two ends of cross bar are provided with U-lag, U-lag line is equally through weigher LOAD CELLS 1 central axis, U-lag is laid the U-loop 5 of opening upwards, U-loop 5 passes the upper draw ring of spring balance 3 and is connected on U-lag by setting nut, cross bar 4 can be made like this to adapt to the hopper 2 of different in width, increase operation rate; For reducing the cost of lower connecting device, ensure reliability simultaneously, can be chosen as metal draw ring 6, metal draw ring 6 can be welded on weigher base 7 or be fixed on ground by ground anchor bolt, selects to be welded on weigher base 7 herein.
The school scale of technical solutions of the utility model is such work: first-selected needs entrusts calibration to the spring balance 3 by use or directly buy, then the lower end of spring balance 3 is connected with metal draw ring 6, cross bar 4 be placed on the top of hopper 2 and adjust the central axis that it passes weigher LOAD CELLS 1, by the upper end of U-loop 5 through spring balance 3, and setting nut is connected on U-lag, rotate setting nut, the reading of spring balance 3 is made to reach the half of range ability to be calibrated, the reading of spring balance 3 is added, then the reading of weigher LOAD CELLS 1 is contrasted, error can be adjusted.
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.
