Tube blank bar material products metering platform balance

Abstract

A tube rod flan material production measurement platform balance mainly solves the technical problems that the body mechanical measuring part is easy to be abraded, the bearing machine mechanical rigid structure is easy to distort and fatigue, the existing platform balance can not adapt and satisfy the measuring precise requirement in long term when the locale traveling crane raising the rod material to produce bigger impact loads and centralizing eccentricity loads, and the measuring errors are influenced by the random drooping length of the steel wire, etc, in the existing platform balance.The key points of the technic proposal are that: the bearing machine is supported and arranged on a bearing base seat, a sensor is arranged between the bearing machine and the bearing base seat, an output information wire of the sensor is connected with a display meter, the bearing machine and the bearing base seat are made from the whole block steel plate flan, the upper part of the bearing machine is provided with an amortizing quakeproof frame, the center of the bearing machine is provided with a steel wire weight block board. The whole structure is simple and compact, the manufacturing, installment, using and maintenance are convenient, more particularly, the anti-impacting ability is strong, and the measurement is more precise and reliable. The invention can be widely applied to the atrocious production environment of the metallurgical industry weighting and measuring in the locale.

Problems solved by technology

[0002] When cranes are used to pick up objects such as billets and bars in the metallurgical industry, large impact loads and concentrated eccentric loads are easily formed on the scales in an instant, and the existing platform scales have a certain amount of mechanical deformation and stress release. Randomness, easy to have a great impact on the stability of measurement results

The commonly used platform scale products usually use a double-layer weighing platform with a buffer device. Its self-weight is about several tons. The rigidity of the structure is very limited to the loading method of major impacts, and with long-term frequent use, the rigid structure will be deformed and fatigued, which will directly affect the measurement characteristics of the sensor; and the load-bearing foundation of the existing platform scale equipment is made of reinforced concrete. Structure or steel welded frame structure, in the long-term use process, according to the analysis of the principles of object dynamics and statics, the original rigid structure of the load-bearing foundation will produce certain cracks and the load-bearing plate will be loosened by welding. becomes smaller, its static friction changes with the change of bearing support force, which will cause poor repeatability and stability of measurement

It is difficult to guarantee the durability of the bearing foundation

Especially as the production pace of the enterprise is accelerated, it is more likely to cause wear of the mechanical measurement parts of the equipment body, aging damage of the sensor device, deformation and fatigue of the mechanical rigid structure of the carrier. When the equipment forms a large impact load and concentrated eccentric load, the length and weight of the steel wire rope are uncertain and other factors will affect the measurement accuracy and stability.
