(54) ГРУЗОЗАХВАТНАЯ СИСТЕМА(54) LOADING SYSTEM

Изобретение относитс к подъемно-транспортному машиностроению, в частности к грузозахватным системам.FIELD OF THE INVENTION The invention relates to lifting and transport machinery, in particular, to load handling systems.

Известна грузозахватна система, содержаща подвешиваемую на крюк крана траверсу, смонтированный на ней ресивер, вакуумные захваты, прикрепленные посредством подвесок к траверсе 1.A known lifting system comprises a yoke suspended from a crane hook, a receiver mounted on it, vacuum grippers attached by means of suspensions to the yoke 1.

Однако известной транспортной системой невозможно захватывать издели различных габаритов.However, the known transport system cannot capture items of various dimensions.

Цель изобретени - повышение эффективности в эксплуатации.The purpose of the invention is to increase efficiency in operation.

Дл достижени указанной цели грузозахватна система снабжена дл разведени траверсы установленной на земле опорой , содержащей стойки с наконечником и горизонтальную балку с ограничител ми максимального разведени траверсы, а траверса выполнена из двух ферм, шарнирно соединенных с ресивером, и снабжена гидроцилиндрами, корпус каждого из которых прикреплен к одной ферме, а шток к другой, при этом полости каждого гидроцилиндра соединены между собой и с полост ми других гидроцилиндров с возможностью одновременного перекрывани .To achieve this goal, the load gripping system is equipped with a support mounted on the ground, containing supports with a tip and a horizontal beam with maximum dilution limiters, and the crosshead is made of two trusses, hinged to the receiver, and equipped with hydraulic cylinders, each of which is attached to one farm, and the rod to another, while the cavities of each hydraulic cylinder are interconnected and with the cavities of other hydraulic cylinders with the possibility of simultaneous overlapping.

Кроме того, подвески вакуумных захватов могут быть закреплены к фермам шарнирно .In addition, the suspensions of the vacuum grippers can be hinged to the trusses.

На стойках опоры могут быть закреплены ролики.Rollers can be fixed on the supports.

5 На фиг. 1 показана грузозахватна система , общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - схема гидросистемы. Грузозахватна система содержит ресивер 1 и вакуумные захваты 2, закреп ,Q ленные посредством подвесок 3 к траверсе , выполненной в виде двух ферм 4, прикрепленных по всей длине к ресиверу 1 посредством шарниров 5. Формы 4 соединены между собой гидроцилиндрами 6 со штоками 7 при помощи шарниров 8.5 In FIG. 1 shows the load gripping system, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - diagram of the hydraulic system. The load gripping system contains a receiver 1 and vacuum grippers 2, secured, Q fixed by means of suspensions 3 to a traverse made in the form of two trusses 4 attached along the entire length to the receiver 1 by means of hinges 5. The shapes 4 are interconnected by hydraulic cylinders 6 with rods 7 by means of hinges 8.

15 Полости 9 и 10 каждого гидроцилиндра 6 сообщаютс между собой и полост ми других гидроцилиндров 6 посредством трубопроводов 11 и запирающего устройства 12, имеющего руко тку 13 управлени . На15 The cavities 9 and 10 of each hydraulic cylinders 6 communicate with each other and the cavities of the other hydraulic cylinders 6 through pipelines 11 and a locking device 12 having a control handle 13. On

Claims

2Q trusses 4, by means of hinges 14, are fixed suspensions 3 of vacuum grippers 2 with the possibility of angular displacement relative to these trusses in the plane of their cross section. To adjust the crosshead to the maximum overall size of the transported goods, the proposed device is equipped with ground supports 15, including tips 16 and rollers 17. In addition, each support has limiters 18 for horizontal movement of trusses 4. For adjusting the crosshead to the required size, a limb 19 is provided. installed at the end of one of the farms 4. The load handling system works as follows. When the traverse is lowered by the load gripping mechanism on the support 15 of the truss 4, they interact with the tips 16, and as they are lowered they interact with the rollers 17, as a result of which the handle 4 13, the locking device 12 is set to the “Open” position. The trusses 4, moving apart, move the rods 7 of the hydraulic cylinders 6, and the liquid in the hydraulic cylinders 6 is squeezed from the cavity 10 into the cavity 9 through the pipe 11 and the locking device 12. The trusses 4 are moved apart until their lower parts reach the stops 18, corresponds to the maximum overall size of B traverse. When the maximum size is reached, the handle 13 is moved to the closed position, stopping the flow of fluid from one cylinder cavity to another, thereby fixing the trusses relative to each other. Then, the traverse is removed from the supports 15. If it is necessary to decrease the distance between the trusses 4, the handle 13 is turned to the "Open" position, and under the action of the gravitational forces of the truss 4 draws together until the reading of the limb 19 corresponds to the size appropriately (Rig .1 load size, then fix the position of the trusses 4 by setting the handle 13 to the position "Closed. The traverse is in a suspended position. After the adjustment is completed, the hoisting-and-transport operations are performed. Application of the proposed transport The systems will provide energy savings as there is no drive. Invention 1. A load gripping system comprising a yoke suspended from a crane hook, a receiver mounted on it, vacuum grippers fixed by means of traverse suspensions, which is different in that , it is equipped for breeding the crosshead, a support mounted on the ground, containing supports with a tip and a horizontal beam with limiters for maximum dilution of the crosshead, and the crosshead is made of two trusses, They are connected to the receiver, and equipped with hydraulic cylinders, the casing of each of which is fixed to one truss and the stem to the other, while the cavities of each hydraulic cylinder are connected to each other and to the cavities of other hydraulic cylinders with the possibility of simultaneous overlapping.

2. The system according to claim 1, characterized in that the suspensions of the vacuum grippers are pivotally attached to the trusses.

3. The system according to claim 1, characterized in that the rollers are fixed on the support legs. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 189539, cl. 66 C 1/02, 1963 (prototype).
