Изобретение относитс к области испытани материалов.The invention relates to the field of testing materials.
Известен навесной пресс дл испытани дорожной конструкции местным нагружением, включаюаднй номкр&т набор плоских штампов и , измер ющих нагрузку и осадку ватампй Домкрат упираетс в раму rpsrateiiOrO автомобил дл прицепа, р«ссары которого блокируютс на период испытани 1 .A hinged press is known for testing a road structure by local loading, including a set of flat dies and a set of flat dies and measuring the load and draft of the ram.
Наиболее, близким из известных вл етс устройство дл исшатаниз дорожного покрыти , включающее сферический штамп с.нагружающим механизмом , упорное и измерительное приспособлени 2.The closest known device is for road paving, which includes a spherical stamp with a loading mechanism, a thrust and a measuring device 2.
Известные устройства не позвол ют определ ть сдвигающие напр сейий в . материале и не обладают достаточной точностью замеров.Known devices do not allow the determination of shifting factors. material and do not have sufficient accuracy measurements.
Цель изобретени - повышение точности определени .The purpose of the invention is to improve the accuracy of determination.
Достигаетс цель тем, что устройство оборудовано балансирным приспособлением , шарнйрно св занным с нагружающим механизмом и упорны приспособлением. Кроме того, балансирное приспособление выполнено вThe goal is achieved by the fact that the device is equipped with a balancing device, which is hingedly connected with the loading mechanism and which is obstinate by the device. In addition, the balancing device is made in
виде двуплечего рычага, однб плечо которого снабжено вилкой, а другое подвижным противовесом.the form of a two-armed lever, one shoulder of which is provided with a fork, and the other a movable counterweight.
На фиг. 1 изображен общий вид предложенного устройства; на фиг. 2 вид сверху на силовой цилиндр.FIG. 1 shows a general view of the proposed device; in fig. 2 is a top view of the power cylinder.
