The invention relates to the technical field of concrete batching scale metering performance calibration and specifically relates to a non-counterweight calibrating device for a concrete batching scale metering performance static test. The calibrating device comprises a force application device, a weighing sensor, a digital display instrument. The weighing sensor is connected with the digital display instrument. The calibrating device further comprises a connecting rod assembly. Two ends of the connecting rod assembly are respectively provided with a roller assembly and a hook. The length of the force application device is adjustable, and two ends are connected with the roller assembly and the hook through chains. The weighing sensor is arranged on the bottom part of the roller assembly. The non-counterweight calibrating device solves the problems the working face is narrow, counterweight transportation and assembling are inconvenient in an existing concrete batching scale metering performance calibration process, the calibration level is improved, and the labor intensity is lowered. By means of gravity effect simulation, non-counterweight calibration is realized. By a screw tightening mode, the length is adjusted, so that the loading of a support surface is realized, and the development of the calibration work is facilitated. The loading process is continuous and adjustable, and the full range of a concrete batching scale is calibrated.
Description
technical field [0001] The invention relates to the technical field of static test calibration of metering performance of batching scales, in particular to a calibration device without weights for the static test of metering performance of concrete batching scales. Background technique [0002] In the production process of ready-mixed concrete, the concrete is input into the control equipment according to the determined mix ratio, and raw materials such as sand, stone, cement, additives, water and chemical additives are automatically weighed, conveyed, and delivered by the weighing control system according to the concrete mix ratio. Stir and feed into the transport tanker. Weighing and measuring control equipment for raw materials—concrete batching scales are particularly important for accurate and reliable weighing, which is not only related to the quality of concrete products, but also affects the cost control of production enterprises. Therefore, the calibration workload...
