FIELD: testing equipment.SUBSTANCE: device comprises a base, supports for fixation of a tested item, a stand, a drive, pusher levers, a cycle counter and a control panel. The drive is made in the form of a gear motor drive with a vertically aligned output shaft of the gear, on which there is a carrier fixed as horizontally arranged in a rigid and cantilever manner. On the horizontal shelf of the carrier there are longitudinal slots, where a vertical axis is fixed as capable of movement along it, and the pusher lever is connected by one end with this axis, and by the other end - with a leaf of the tested item, besides, spherical bearings are installed in units of its fixation. The gear motor drive is mounted on the stand as capable of movement in 3 mutually perpendicular directions. A voltage frequency controller is installed into a circuit of power supply of the gear motor drive. The cycle counter is equipped with a pulse sensor electrically connected to it and comprising a sensor itself, installed, for instance, on the support, and a steel plate, installed, for instance, on the leaf and interacting with it as the leaf is being opened and closed.EFFECT: simplified design, reduced consumption of energy and labour intensiveness of works.3 dwg |
