() ОГРАНИЧИТЕЛЬ УГЛА НАКЛОНА ГРУЗОЗАХВАТНОГО ОРГАНА МЕХАНИЗМА ПОДЪЕМА ГРУЗОПОДЪЕМНОГО () LIMITER OF THE ANGLE OF THE TILT OF THE LOADING ORGANIZATION MECHANISM OF RAISING THE LOADING CAPACITY

II

Изобретение относитс к подъемнотранспортному оборудованию, а именно к предохранительным устройствам грузоподъемных сред(;тв, и может быть использовано дл ограничени угла наклона грузозахватного органа грузоподъемного средства, преимущественно крана.The invention relates to lifting equipment, namely, safety devices for lifting media (; TV, and can be used to limit the angle of inclination of the lifting body of the lifting means, preferably a crane.

Известен ограничитель угла наклона грузозахватного органа механизма подъема грудоподъемного средства, содержащий корпус, на дне которого расположены токопровод щий шарик и нижний электрический контакт, а верхний электрический контакт устан лен в корпусе с возможностью вертикального перемещени , причем корп соединен с опорной площадкой грузозахватного органа tl. Недостатком известного ограничител вл ютс сравнительно узкие эксплуатационные возможности. цель изобретени - расширение эксплуатационных возможностей ограСРЕДСТВАA known limiting angle of inclination of the lifting body of the lifting mechanism of the breast lifting means comprises a housing at the bottom of which a conductive ball and a lower electrical contact are located, and the upper electrical contact is mounted in the housing with vertical movement, and the building is connected to the supporting platform of the lifting body tl. A disadvantage of the known limiter are relatively narrow operational capabilities. The purpose of the invention is to expand the operational capabilities of the facility.

ничител за счет ограничени угла наклона грузоподъемного органа в зависимости от веса груза.by tilting the load-lifting organ depending on the weight of the load.

Указанна цель достигаетс тем, что ограничитель снабжен обоймой, св занной с механизмом подъема, упругим элементом, соединенным с обоймой, и скобой, посредством которой верхний электрический контакт св зан с грузозахватным органом, This goal is achieved by the fact that the limiter is provided with a clip associated with the lifting mechanism, an elastic element connected to the clip and a clip, by means of which the upper electrical contact is connected with the load gripping body,

10 установленным на упругом элементе, причем опорна площадка установлена на обойме.10 mounted on an elastic element, the support pad being mounted on the cage.

Claims

The drawing shows the limiter of the angle of the lifting body. general form. The tilt angle limiter of the lifting mechanism of the lifting device means comprises a housing 1, at the bottom of which a conductive ball 2 is located, and a lower electrical contact 3. The upper electrical contact is installed in the housing 1 with the possibility of radial movement. The contacts 3 and i can be made annular. The frame 1 is connected to the support platform 5, mounted on the holder 6, which is connected with the lifting mechanism of the lifting means (not shown), and the holder 6 is connected to the beam 7 for fastening the blocks of the cargo hoist mechanism. Contact 4 is connected with skobaya 8, which is installed on the load gripping body 9. The load gripping body 9 is laid on the elastic element 10 located on the yoke 6. The tilt angle limiter of the load gripping body of the lifting mechanism of the load-lifting means works (as follows. When tilting the load gripping body 9 tilts and body 1 in which the ball moves

2. Depending on the weight of the load, the load gripping body 9 compresses the elastic element 10 by an appropriate amount, in which case the clamp 8 moves and lowers to the stroke. With a small weight of the load, the contact is located above the ball 2 and the angle of inclination of the load gripping body is not limited. With a relatively large weight of the load, the contact k is lowered so much that when the load gripping body 9 is tilted, the ball 2 closes contact 3 and A and a signal is given about an unacceptable tilt angle of the load gripping body. The nalon angle limiter allows, when lifting only relatively large loads by weight, to limit the angle of inclination of the load gripping body, and therefore the performance of the limiter expands. Claims of the invention A tilt angle limiter of a lifting body of a lifting mechanism of a lifting device comprising a housing at the bottom of which a conductive ball and a lower electrical contact are located, and the upper electrical contact is installed in the housing with the possibility of vertical movement, the housing being connected to a supporting platform of the lifting body differing the fact that, in order to expand operational capabilities by limiting the angle of inclination of the load gripping body depending on the weight of the load, It is provided with a cage, associated with the lifting mechanism, an elastic element connected with a holder, and a bracket through which the upper electrical contact associated with the lifting body mounted on the elastic member, wherein the support platform is mounted on a holder.
