Изобретение относитс к грузозахватным устройствам.The invention relates to lifting devices.

Известно захватное устройство дл штучных грузов, содержащее навешиваемую н-а грузоподъемную машину раму с поворотными захватными лапами и зажимными башмаками |1.Known gripping device for piece goods, containing hanging on a lifting machine frame with swivel gripping legs and clamping pads | 1.

Однако оно не обеспечивает охлаждени издели при его транспортировке.However, it does not provide cooling for the product during transportation.

Цель изобретени - расширение функциональных возможностей путем охлаждени транспортируемых изделий.The purpose of the invention is to expand the functionality by cooling the transported products.

Цель достигаетс тем, что рама выполнена с полостью дл охлаждаюшей жидкости при этом в нижней части рамы выполнены отверсти , в которых установлены клапаны, кроме того, зажимные башмаки и рама снабжены опорными ребрами, смещенными относительно друг друга на величину, равную половине их шага.The goal is achieved by the fact that the frame is made with a cavity for the cooling liquid, and in the lower part of the frame there are holes in which valves are installed, in addition, the clamping shoes and the frame are provided with supporting ribs offset from each other by an amount equal to half their pitch.

На фиг. 1 изображен захват, общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - захват, вид сбоку.FIG. 1 shows the capture, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - capture, side view.

Захват состоит из траверсы 1, к которой шарнирно подвешены т ги 2, шарнирно соединенные с захватными лапами 3, которые поворачиваютс вокруг осей 4, установленных на общей раме 5, и на концах снабжены шарнирно закреплёнными зажимными башмаками 6. Траверса 1 и рама 5 соединены между собой механизмом 7 фиксации захватных органов в раскрытом положении. Рама 5 выполнена с полостью дл охлаждающей жидкости с конусными отверсти ми в днище и установленными в них клапанами 8. Клапаны 8 помещены в направл ющие 9 и шплинтами 10 удерживаютс от случайного выпадани . Направл ющие 9 The grip consists of a yoke 1, to which hinges 2 are pivotally suspended, pivotally connected to the gripping legs 3, which rotate around the axes 4 mounted on a common frame 5, and at the ends are provided with pivotally fixed clamping shoes 6. Traverse 1 and frame 5 are connected a mechanism of fixing 7 gripping bodies in the open position. The frame 5 is made with a cavity for coolant with tapered holes in the bottom and valves 8 installed in them. Valves 8 are placed in guides 9 and claws 10 are prevented from accidentally falling out. Guides 9

10 жестко св заны с рамой 5 и имеют отверсти дл прохода жидкости. Рабочие поверхности рамы и зажимных башмаков 6 снабжены опорными ребрами 11, расположенными с определенным шагом, причем опорные ребра зажимных башмаков 6 смещены относительно опорных ребер рамы 5 на величину , равную половине их шага.10 are rigidly connected to frame 5 and have openings for the passage of fluid. The working surface of the frame and clamping shoes 6 provided with supporting ribs 11 arranged with a certain pitch, and the supporting edges of the clamping shoes 6 are offset relative to the supporting edges of the frame 5 by an amount equal to half of their pitch.

Захват работает следуюшим образом.Capture works as follows.

Claims

In the initial position, the gripping points 3 with the shoes 6 are fixed by the fixation mechanism 7 in the open position. The cavity of the frame 5 is filled with coolant, and the valves 8 close the outlet openings, preventing its exit. In this position, the grip is lowered onto the load. When the frame 5 stops in it, the valves 8 open the conical holes of the frame 5 and the cooling liquid flows to the load to be loaded. Simultaneously, the mechanism of fixation 7. When lifting, the clamping shoes 6 clamp the load and transport it to the coolant bath for complete cooling. During transportation, the cargo is continuously washed by coolant coming from the cavity of the frame 5 through the open holes. The load is lowered into the coolant bath, whereby the cavity of the frame 5 is filled with liquid through the opening in the upper cavity of the frame, the paws 3 are opened and the fixation mechanism 7 is fixed in the opened position. The gripper rises up, while the valves 8 are lowered and block the conical apertures of the frame 5. The gripper, filled with coolant, is ready for the next cycle. The proposed grip allows continuous cooling of the transported product without additional energy costs. Claims for clamping loads, comprising a frame visited by a lifting machine with swivel gripping legs and clamping shoes, characterized in that, in order to enhance the functionality by cooling the products to be transported, the frame is made with a cavity for coolant, while in the lower part the frames are made holes, in which valves are installed, in addition, the clamping shoes and the frame are provided with supporting ribs that are offset relative to each other by an amount equal to n half of their step.
