Novel cement counterweight

Abstract

A novel cement counterweight is characterized in that a handle is connected with a glass fiber layer, the glass fiber layer is connected with a reinforced concrete layer, an iron block is arranged in the reinforced concrete layer, an identification code is arranged in the upper right side of the glass fiber layer, the glass fiber layer is formed by glass fiber and resin, the reinforced concrete layer is formed by steel bars and concrete, and the steel bar is of a grid structure filled with concrete. The iron block arranged in the reinforced concrete layer is protected by the glass fiber layer and the reinforced concrete layer to retain the iron block stainless for a long time and increases the weight of the cement counterweight. The handle is installed on the counterweight to facilitate moving. The counterweight is weighted according to a standard scale. The weight after weighing is written in the identification code, and the identification code is pasted on the counterweight to facilitate checking of the weight. The cement counterweight is low in production cost and simple in structure, and is stainless, economical and durable.

Description

technical field [0001] The invention belongs to the technical field of detection and measurement, in particular to a novel cement weight. Background technique [0002] In the Xia Dynasty, "Quan" equivalent to weights appeared in China. For more than 4,000 years since then, different dynasties have "Quan" with different shapes and materials as measuring tools. In modern mass measurement, weights are the transmission of mass and value. Standard measuring tools, the mass value is based on the platinum-iridium alloy kilogram prototype stored in the French International Bureau of Weights and Measures as the only benchmark. All countries divide weights into national kilogram benchmarks, national kilogram sub-standards, kilogram work benchmarks, and kilograms. The work benchmark group and various work standard weights composed of multiples and weights, in the past in Europe, in order to exchange better equivalents, some people used a lever with sheep and cattle to try to achieve ba...

Problems solved by technology

[0002] In the Xia Dynasty, "Quan", which was equivalent to a weight, appeared in China. For more than 4,000 years since then, different dynasties have "Quan" with different shapes and materials as measuring tools , in modern mass measurement, the weight is the standard measuring tool for the transmission of the mass value, and the mass value is based on the original platinum-iridium alloy kilogram preserved in the French International Bureau of Weights and Measures as the only reference device. All countries divide the weight into national kilograms Benchmarks, national sub-standards for kilograms, working benchmarks for kilograms, and working benchmark groups composed of multiples and weights of kilograms and various working standard weights. In the past, in Europe, for better equivalent exchange, some people had sheep and cattle. Use a lever to achieve balance as much as possible. At that time, the so-called sheep or cattle were used as the earliest weights, but as time went by, there were gradually prototype weights made of stones, but the error was large at that time. So after thousands of years of continuous evolution, processing and reprocessing, it has become today's weights, and made of stainless steel marked weights, precision weights, etc.; this kind of weight will be inaccurate after being used for a long time The phenomenon is mainly caused by two reasons. On the one hand, the wear of the weight will occur after the weight is used for a long time, which is very harmful to the use of the weight. On the other hand, it is caused by rust. Inaccurate phenomenon, which requires us to pay attention to storage when using it. Even stainless steel weights will rust if they are used in an environment containing chloride ions for a long time, such as salt, sweat, sea water, soil, etc. However, when After the weight is worn or rusted, the weighing result will of course be affected. If the weight is rusted, the measurement result will be too small, and if the weight is worn, the measurement result will be too large, because if the weight is rusted, the surface of the stainless steel weight will Iron forms iron oxide, with more oxygen atoms, of course its mass will become heavier, and the weight of the weighing item obtained will be relatively reduced. It is not difficult to understand that the weight wear measurement results are too large for the same reason; these weights If the weighing result is inaccurate, it can only be scrapped, and because the cost is too high, scrapping will cause a great waste of resources, especially in some places where the accuracy is not too high, but weights must be used frequently, this kind of expensive The weights seem out of place, the present invention is to study a simple structure, no rust, large volume, economical and durable a new type of cement weights
