Intelligent determining device of cement consistence and coagulation time

Abstract

The invention discloses an intelligent determining device of cement consistence and coagulation time. The intelligent determining device comprises a base and a bracket, wherein the bracket is fixed on the base, a base plate, a glass plate and a conical mould are sequentially arranged on the base from bottom to top, an upper sliding sleeve and a lower sliding sleeve which are coaxial are arranged on the bracket vertical to the direction of the conical mould, a sliding rod sleeves between the upper sliding sleeve and the lower sliding sleeve in a penetrating way, a lifting device capable of lifting the sliding rod is arranged on the bracket, the sliding rod between the upper sliding sleeve and the lower sliding sleeve is provided with a fixed ring, a pointer is arranged on the fixed ring, a scale plate corresponding to the pointer is arranged at one side of the sliding rod between the upper sliding sleeve and the lower sliding sleeve, and an upper travel switch and a lower travel switch which correspond to the pointer are arranged at two ends of the scale plate. According to the intelligent determining device, intelligent determination of cement consistence and coagulation time is realized, when the pointer is in contact with the lower travel switch, the lifting device is used for lifting the sliding rod, when the sliding rod is lifted until the pointer is in contact with the upper travel switch, switching of an initial coagulation testing needle and a final coagulation testing needle is realized by virtue of rotation of a converter, so that tedious operation of assembling and dissembling a needle head in a testing process is prevented.

Description

technical field [0001] The invention relates to the technical field of traffic paving equipment, in particular to an intelligent measuring device for cement consistency and setting time. Background technique [0002] At present, in the early stage of pavement and bridge construction, it is necessary to carry out standard determination of cement, including the determination of cement consistency and setting time. The cement paste with standard consistency has certain resistance to the sinking of the standard test rod. By testing the penetration of cement paste with different water content, to determine the amount of water that needs to be added to the cement paste with standard consistency. The setting time is the time required for the test needle to sink into the cement standard consistency slurry to a certain depth. [0003] At present, when testing cement indicators in the existing technology, most of them are to replace the test needle after testing one indicator and th...

Problems solved by technology

[0003] At present, when testing cement indicators in the existing technology, most of them are to replace the test needle after testing one indicator and then test the next item. The intelligence is low, time-consuming and labor-intensive, resulting in low work efficiency, and the accuracy of the test results is low. The accuracy is not high, there are some defects
