Description
На фиг. 1 изображена предложенна установка; на фиг. 2 - то же, вид сверху; на фиг. 3 - плита с кронштейном и опора.FIG. 1 shows the proposed installation; in fig. 2 - the same, top view; in fig. 3 - plate with bracket and support.
Устройство состоит из пр моугольной платформы 1, к которой подвешена силова плита 2 с кронштейном 3, в котором посредством двухплоскостного шарнира 4 закреплена опора 5 в виде шасси транспортного средства при динамическом испытании или домкрата со штампом при статическом испытании.The device consists of a rectangular platform 1, to which the force plate 2 with the bracket 3 is suspended, in which the support 5 is fixed in the form of a vehicle chassis during dynamic testing or a die with a stamp during static testing by means of a two-plane hinge 4.
Нагрузка на испытуемое основание создаетс весом балласта 6, нагружаемого на платформу 1. Балластом могут служить, например, железобетонные плиты, которые груз тс таким образо.м, чтобы центр т жести его совпадал с осью шарнира. Точность центровки контролируетс по обжатию угловых транспортных колес 7.The load on the test base is created by the weight of the ballast 6, which is loaded onto platform 1. For example, reinforced concrete slabs can be used as ballast, which are loaded so that its center of gravity coincides with the hinge axis. The alignment accuracy is controlled by the reduction of the angled transport wheels 7.
Транспортировка устройства осуществл етс автот гачо.м или лебедкой. Дл этого на торцовых балках платфор.мы 1 закреплены кронштейны 8 дл креплени водила 9. На установке предусмотрены два водила, что дает возможность работать на узких плошадках без разворота .The device is transported by auto gacho.m or winch. For this purpose, on the end beams of the platform. We have fixed brackets 8 for fastening the carrier 9. The device has two carriers, which makes it possible to work on narrow planes without turning.
Работа устройства заключаетс в следуюшем .The operation of the device is as follows.
При динамических испытани х дорожных покрытий аэродромов или дороги перед начало .м движени установка загружаетс балластом 6, передние колеса ориентируютс эксцентриситетом в сторону, противоположную движению.In dynamic tests of the pavements of aerodromes or of the road before the beginning of the movement, the installation is loaded with ballast 6, the front wheels are oriented with eccentricity in the opposite direction of movement.
Установка буксируетс т гачом. При статических испытани х покрыти аэродрома, дороги или определени несушей способности грунтового основани опора 5 замен етс на гидравлический домкрат со шта.мпо.м. Дл пере.мещени устройства с одной обследуемой точки на другую водила 9 переставл ютс в одну изThe unit is towed with a slack. In static tests of the airfield pavement, road, or the determination of the capacity of the soil foundation, the support 5 is replaced with a hydraulic jack with a standard gauge. To move the device from one surveyed point to another, the carrier 9 is moved into one of the
боковых сторон рамы, колеса поворачиваютс и фиксируютс дл движени в боковом направлении . Образующа с при боковом движении устройства широка коле не оказывает вли ни на обследуемую полосу основани или покрыта , что позвол ет не снимать балласт б при транспортировке устройства.the sides of the frame, the wheels are rotated and fixed to move in the lateral direction. The wide collar formed during lateral movement of the device does not affect or is covered by the base strip being examined, which makes it possible not to remove ballast b when transporting the device.
Таким образом, устройство дл испытани прочности аэродро.мных и дорожных покрытий обеспечивает проведение статических и динамических испытаний, исключает трудое.мкую и долговременную операцию по разгрузке балласта и тем самым резко повышает производите .льность устройства.Thus, the device for testing the strength of airfield and road pavements provides static and dynamic tests, eliminates the difficult and long-term operation of unloading ballast and thereby sharply increases the production of the device.
