(54) ЗАХВАТНОЕ УСТРОЙСТВО(54) CAPTURE DEVICE

1one

Изобретение относитс к подъемнотранспортному машиностроению, в частности к захватным устройствам.FIELD OF THE INVENTION The invention relates to lifting transport machinery, in particular to gripping devices.

Известно захватное устройство, со- Держащее подвеску и шарнирно прикрепленный к ней крюк 1 .A gripping device is known that contains a suspension and a hook 1 attached to it pivotally.

Известное устройство не обеспечивает надежной фиксации груза.The known device does not provide reliable fixation of the load.

Целью изобретени вл етс расширение эксплуатационных возможностей.The aim of the invention is the expansion of operational capabilities.

Цель достигаетс тем, что устройство снабжено двум дополнительными крюками , шарнирно прикрепленными к подвеске по обеим сторонам основного крюка, выполненного с отверстием, в котором размешена ось шарниров дополнительных крюков, при этом зевы всех крюков вьшолнены и-образным и.The goal is achieved by the fact that the device is equipped with two additional hooks pivotally attached to the suspension on both sides of the main hook, made with a hole in which the axis of the additional hooks hinges are stirred, while all the hooks are i-shaped and e-shaped.

На фиг. 1 изображено захватное устройство , разрез; на фиг. 2. - А-А на фиг. 1.FIG. 1 shows a gripping device, a slit; in fig. 2. - A-A in FIG. one.

Устройство содержит крюки 1 и 2, имеющие симметрично скошенные внутренние поверхности и закрепленные шарнирно на подвеске 3. Ось 4 закреплена в крюке 1 и щзоходит через паз крюка 2, а пружина 5 закреплена на подвеске 3 и зацеплена за крюк 2. В захвате транспортируетс деталь 6.The device contains hooks 1 and 2, which have symmetrically beveled inner surfaces and are hinged on the suspension 3. Axle 4 is fixed in hook 1 and goes through the groove of hook 2, and spring 5 is fixed on suspension 3 and hooked to hook 2. In the gripper, part 6 is transported .

Захватное устройство работает следующим образом.The gripping device operates as follows.

В свободном положении, без груза, пружина 5 поднимает вверх до упора . крюк 2, который через ось 4 поднимает In the free position, without load, the spring 5 raises up to the stop. hook 2, which through axis 4 raises

10 также крюк 1 в исходное положение. При этом захват, раскрыт на максимальную величину.10 also hook 1 to its original position. In this seizure, disclosed to the maximum value.

Claims

When the gripper is loaded, the part 6 with its weight turns hooks 1 and 2 on the axes of their attachment. At the same time, the inner symmetrically beveled surfaces of the hooks I and 2, which together form the clamping prism, are assembled all the way into the part 6 and, thereby, fix it, pressing it to the lower base surfaces of the hooks 1 and 2 constituting the tick pair. 39 When the part 6 is gripped, the presser angle of the grimace decreases with decreasing part diameter. To eliminate this, the fastening of the pair of tongs to the suspension 3 can be carried out via four-wheel mechanisms (not shown). The main advantage of a tfedlagaemog device compared to the known one is that it allows you to expand the technological capabilities and capture parts of both different sizes and configurations. Claims of the invention A gripping device comprising a suspension and a hook pivotally attached to it 1, characterized in that, in order to expand its operational capabilities, it is equipped with two additional hooks pivotally attached to the suspension on both sides of the main hook made with a hole in which the axis is placed hinges additional hooks, irk this throat all hooks are made of shaped.
