(54) ЗАХВАТ ДЛЯ ШТУЧНЫХ ГРУЗОВ(54) CAPTURE FOR PIECE CARGOES

Изобретение относитс к грузоподъемно му оборудованию, а именно к захватам дл штучных грузов.The invention relates to lifting equipment, namely to grips for piece goods.

Известен захват дл штучных грузов, например, имеющих форму диска с центральным отверстием, содержащий грузо- . несущую раму, св занную в верхней своей части со скобой дл навещивани на грузоподъемное устройство, причем грузонесуща рама представл ет собой кольцо, одеваемое на цилиндрическую поверхность диска. Захват снабжен также зажимом, фиксирую- Q щим груз в упом нутом кольце 1.Known capture for piece goods, for example, having the form of a disk with a central hole, containing cargo. a supporting frame connected in its upper part with a bracket for visiting a lifting device, the load-carrying frame being a ring worn on the cylindrical surface of the disc. The gripper is also provided with a clip securing the load in said ring 1.

Недостатком этого захвата вл етс узкий диапазон его применени , так как диаметр кольца, одеваемого на дискообразный груз, должен соответствовать диаметру последнего .15The disadvantage of this grip is the narrow range of its use, since the diameter of the ring that is put on the disc-shaped weight must correspond to the diameter of the latter .15

Кроме того, работа захвата осуществл етс при взаимодействии его рабочего органа - кольца со всей цилиндрической поверхностью захватываемого груза, что во многих случа х нежелательно ввиду возможного повреждени этой поверхности. 20In addition, the work of gripping is carried out in the interaction of its working body, the ring, with the entire cylindrical surface of the load to be gripped, which in many cases is undesirable because of possible damage to this surface. 20

Известен также захват дл штучных грузов , содержащий грузонесущую раму, св занную в верхней своей части со скобойA grip for piece goods is also known, containing a load carrying frame connected in its upper part with a bracket.

дл навешивани на грузоподъемное устройство и выполненную в виде шарнирнорычажного механизма. Шарнирно-рычажный механизм представл ет собой две вертикальные рамные стенки, св занные между собой двум стержн ми, причем одна из стенок в нижней части оборудована полкой, на которую может быть установлен «на ребро груз дискообразной формы, подлежащий захватыванию.for hanging on a lifting device and made in the form of a toggle mechanism. The hinged-lever mechanism consists of two vertical frame walls connected between each other by two rods, one of which in the lower part is equipped with a shelf on which a disk-shaped load to be gripped can be mounted on the edge.

Захват обеспечивает возможность захватывани и удержани дискообразных грузов различного диаметра в положении «на ребро, оставл при этом центральное отверстие свободным доступу 2.The gripper provides the possibility of gripping and holding disc-shaped weights of various diameters in the "edge" position, while leaving the central opening free access 2.

Однако известный захват захватывает и зажимает груз с обоих торцов, что это может привести к повреждению значительной части его торцовой поверхности.However, the known grip seizes and clamps the load from both ends, which can damage a significant part of its end surface.

Цель изобретени - обеспечение сохранности захватываемого груза.The purpose of the invention is to ensure the safety of the captured cargo.

Claims

The goal is achieved by the fact that in the gripper containing a load-carrying frame, connected in its upper part with a bracket for hanging on a lifting device and made in the form of a hinged-lever mechanism, the latter is made in the form of a hinged multi-link, whose links are connected in series with each other, one of the hinges is connected to the bracket, and on the hinges and links of the multi-link there are pins that cover the load. FIG. 1 - general view; in fig. 2 - side view. The gripper contains a load-carrying frame in the form of a hinged-lever mechanism, which is a vertically located hinge terminal, the links of which are sequentially connected to each other. One link of this patch is strap 1 horizontally below, the ends of the strap are connected by means of hinges 2 and 3, respectively, to two other links — racks 4 and 5, which by means of hinges b and 7 are connected respectively to bars 8 and 9. T The gigs 8 and 9 are interconnected by means of a hinge 10, which is connected with a shackle 11 for hanging the grip on a lifting device. The hinges 2 and 3 are equipped with pins 12. There are grooves 13 on the pillars 4 and 5, in which the pins 14 are fixedly movable. The pins can be rubberized to prevent damage to the surface of the cargo in contact with them. Capture works as follows. The grip is directed to the load in such a way that the pins 12 and 14 cover the load. When lifting the grip by the bracket 11, ti gi 8 and 9 turn around the hinges b and 7, stand 4 and 5, which, in turn, turn around the hinges 2 and 3 under the force of the load weight, clamp the load between pins. The grip can be made in the form of a hinged dies with a different number of links, starting with four. The invention makes it possible to work with the seizure with cargoes of various diameters while at the same time ensuring better safety of the goods due to minimal contact with their surface. At the same time, it is also possible to install disk-shaped weights with a central hole, for example, forming circles, on the mandrel and relieve the load from gripping without interference. Claims for piece goods, for example, in the form of a disk with a central hole, containing a load-carrying frame associated with its upper part with a bracket for hanging on a lifting device and made in the form of a hinge-lever mechanism, characterized in that the safety of the cargo, the hinge-lever mechanism is made in the form of a hinged dies, the links of which are sequentially connected to each other, one of the hinges is connected to the bracket, and the hinges and links of the dies are installed axles covering the load.
