Description

Изобретение относитс  к технике контрол  технологических процессов строительного производства, а именно контрол  степени уплотнени  бетонной смеси в процессе изготовлени  бетонHtjx и железобетонных изделий; Дл  контрол  степени уплотнени  бетонной смеси в процессе изделий известен способ, основанный на измерегнии и анализе динамических характеристик контракции 1. Однако в этом способе довольно трудно зафиксировать момент стабилизации окончани  обработки бетона. Наиболее близким к изобретению по технической сущности  вл етс  способ контрол  степени уплотнени  бетонной смеси в процессе изготовлени  изделий, включающий измерение потребл емой вибратором мощности и определе , ние момента окончани  уплотнени  2 В этом способе момент окончани  процесса виброуплотнени  определ ют путем измерени  электрической мощности потребл емой электромеханическим вибратором . При этом контроль потребл емой мощности осуществл етс  прибором включенным в цепь питани  вибратора. Однако этот способ также не позвол  ет достигнуть приемлемой точности,поскольку на результатыконтрол  сильное вли ние оказывают как колебани  напр жени  сети, так и пусковой переходной процесс электромеханического вибратора. Кроме того, врем  стабилизации , потребл емой электромеханическим вибратором мс цности, зависит от мощности вибратора и массы формируемого издели . При малой массе издели  по сравнению с массой виброплощадки практически невозможно различить кривые переходного процесса с изделием и без издели . Целью изобретени   вл етс  повышение точности контрол . Это достигаетс  тем, что в способе контрол  степени уплотнени  бетонной смеси в процессе изготовлени  изделий , включающем измерение потребл емой вибратором мощности и определение момента окончани  уплотнени  дополнительно измер ют отдаваемую вибратором мощность, а момент окончани  уплотнени  определ ют по отношению потребл емой вибратором мощности к отдаваемой. На чертеже показана одна из возможных схем практической реализации способа.The invention relates to a technique for controlling technological processes of building production, namely, controlling the degree of compaction of a concrete mix in the course of manufacturing concrete Htjx and reinforced concrete products; To control the degree of compaction of the concrete mix in the process of products, a method is known based on measuring and analyzing the dynamic characteristics of contraction 1. However, in this method it is rather difficult to fix the moment of stabilization of the end of concrete processing. The closest to the invention to the technical essence is a method for controlling the degree of compaction of a concrete mix in the process of manufacturing products, including measuring the power consumed by the vibrator and determining the end of compaction 2 In this method, the end time of the vibro-compaction process is determined by measuring the electrical power consumed by the electromechanical vibrator At the same time, the power consumption is controlled by the device included in the power circuit of the vibrator. However, this method also does not allow achieving acceptable accuracy, since the results of the control are strongly influenced by both the voltage fluctuations of the network and the starting transient process of the electromechanical vibrator. In addition, the stabilization time consumed by an electromechanical vibrator ms value depends on the power of the vibrator and the mass of the product being formed. With a small mass of the product in comparison with the mass of the vibrating plate, it is almost impossible to distinguish transition curves with and without the product. The aim of the invention is to improve the accuracy of control. This is achieved by the fact that in the method of controlling the degree of compaction of the concrete mix during the manufacture of products, including measuring the power consumed by the vibrator and determining the moment of the end of the seal, the power supplied by the vibrator is additionally measured, and the moment of the end of the seal is determined by the ratio of the power consumed by the vibrator to that given. The drawing shows one of the possible schemes for the practical implementation of the method.

Блок-схема включает в себ  виброплощадку 1 с изделием, жестко св занную с электромеханическим вибратором 2, источник питани  3, прибор 4 дл  измерени  потребл емой вибратором мощности, прибор 5 дл  измерени  отдаваемой вибратором мощности, измеритель отношени  б и регистрирующее устройство 7, При этом прибор 4 дл  измерени  потребл емой вибратором мощности включен в цепь питани  электромеханического вибратора, а прибор 5 дл  измерени  отдаваемой мощности установлен на выходе вибратора , например на валу электродвигател  .The block diagram includes a vibrating plate 1 with a product, rigidly connected with an electromechanical vibrator 2, a power source 3, a device 4 for measuring the power consumed by the vibrator, a device 5 for measuring the power delivered by the vibrator, a ratio meter b and a recording device 7, A device 4 for measuring the power consumed by the vibrator is connected to the power supply circuit of an electromechanical vibrator, and a device 5 for measuring output power is installed at the output of the vibrator, for example, on an electric motor shaft.

Контроль степени уплотнени  бетонной смеси осуществл етс  следующим образом.Control of the degree of compaction of the concrete mix is carried out as follows.

При включении электромеханического вибратора 2 приборами 4 и 5 измер ют мощнхэсти, потребл емую и отдаваемую .вибратором. Затем результаты измерени  подают на измеритель отношени  б и по стабилизации показаний регистрирующего устройства 7 определ ют окончание процесса уплотнени  бетонной смеси. При этом момент окончани  процесса уплотнени  можно определить как по отношению потребл емой вибратором мс цности к отдаваемой, та1Г и по отношениТб отдаваемой вибратором мощности к потребл емой.When the electromechanical vibrator 2 is turned on with devices 4 and 5, the power of the electros consumed and returned by the vibrator is measured. Then, the measurement results are fed to the ratio meter B and, by stabilizing the readings of the recording device 7, the completion of the concrete mixture compaction process is determined. At the same time, the moment of the end of the compaction process can be defined as the ratio of the ms consumed by the vibrator to the value given, and the ratio of the power given by the vibrator to the consumed value.
