Automatically weight loading tare weight-removing device for electronic hoist scale

Abstract

The invention discloses an automatically weight loading tare weight-removing device for an electronic hoist scale, a balance lever is arranged on a balance fulcrum, and the balance lever can rotate with the balance fulcrum being used as a fulcrum; a balance counterweight is arranged on the balance lever; the balance counterweight includes a counterweight body and a connecting rod, the connecting rod is connected with the balance lever, and the counterweight body is arranged on the connecting rod and can move on the connecting rod; a first connecting assembly and a second connecting assembly are arranged on both ends of the balance lever; one end of a weight loading mechanism is connected with the first connecting assembly while the other end is used for hanging balance weights; the secondconnecting assembly is connected with a weight connecting device of the electronic hoist scale; the balance weights can be loaded on the weight loading mechanism and therefore weight of the weight connecting device is balanced. Via the device disclosed in the invention, the electronic hoist scale can be connected with the weight connecting device, balance can be realized via leverage principles, and that detection of the electronic hoist scale can be started from zero can be ensured.

Description

technical field [0001] The invention relates to the field of weighing and measuring, in particular to a weight-loading tare-free device for an electronic crane scale. Background technique [0002] At present, the detection of electronic crane scales in my country mainly uses standard weights or "substitution method" for detection. For large-tonnage electronic crane scales, when traditional standard weights are used for loading, the weights are manually connected in series or loaded mechanically. string. Due to the large mass and volume of the required weights, a special connection device (usually such as a wire rope, a special connection ring, etc.) is required to connect the weight and the crane scale. the quality of. At present, with the electronic crane scale, the weighing range is getting bigger and bigger, and the accuracy is getting higher and higher. When the weighing accuracy of some electronic crane scales needs to be tested for small weighing, the quality of the ...

Problems solved by technology

Since this detection method requires tare operation, it is difficult to objectively reflect the performance of the zero point error of the electronic crane scale, the minimum weighing point, etc., especially for the detection of the electronic crane scale that needs to be exempted from tare small weighing and accurate weighing. , it is difficult to be accurate and reliable

[0003] At the same time, this operation method does not comply with the relevant regulations on the detection method of electronic crane scales in the national verification regulations, and there are risks in the reliability and accuracy of the traceability of the value.
