Description

Изобретение относится к подъемно'транспортному оборудованию, а именно к захватным устройствам.The invention relates to lifting and transport equipment, namely to grippers.

Известно захватное устройство, содержащее Г-образную траверсу с двумя подхватными лапами и строповую подвеску М·Known gripping device containing a L-shaped traverse with two lifting legs and a sling suspension M ·

Недостатком его является недостаточная надежность йз—за возможности спадания груза с подхватных лап.Its disadvantage is the insufficient reliability of the ss — because of the possibility of the load falling from the catch legs.

Цель изобретения - повышение надежности работы за счет предотвращения спадания груза с подхватных лап.The purpose of the invention is to increase the reliability by preventing falling of the load from the lifting legs.

Указанная цель достигается тем, что в горизонтальной части Г-образноЙ траверсы выполнены отверстия, через которые ’ пропущены одни ветви строповой подвески, снабженные ограничительными упорами, взаимодействующими с Г-обраэной _мтраверсой и кольцами, надеваемыми на подхватные лапы, а также тем, что подхватные лапы снабжены упорами для фиксации колец на них.This object is achieved in that the horizontal portion of the L-shaped yoke are provided with holes through which the 'one branch sling suspension omitted provided with limiting stops that interact with T-obraenoy _m crosspiece and rings worn on podhvatnye paw, and in that podhvatnye paws are provided with stops for fixing rings on them.

На фиг. 1 схематически изображено предлагаемое захватное устройство, об— ₍ щий вид; на фиг. 2 - то же вид сбоку.In FIG. 1 schematically shows the proposed gripping device, general— ₍ general view; in Fig. 2 is the same side view.

Устройство содержит Г—образную траверсу 1 с двумя подхватными лапами 2 ⁵ и строповую подвеску, включающую связанные ί общей серьгой 3 четыре ветки, стропа, две «з которых 4 закреплены в верхней части траверсы 1, а две другие 5 пропущены через отверстия 6, выполненные в горизонтальной части траверсы 1, и снабжен ограничительными упорами 7 и кольцами 8 на концах для лап 2. При этом лапы 2 снабжены упорами 9 для фиксации колец 8 на лапах 2.The device contains a L-shaped traverse 1 with two grasping legs 2 ⁵ and a sling suspension, including four branches connected by a common earring 3, a sling, two of which 4 are fixed in the upper part of the traverse 1, and two other 5 are passed through holes 6 made in the horizontal part of the traverse 1, and is equipped with limit stops 7 and rings 8 at the ends for the legs 2. Moreover, the legs 2 are equipped with stops 9 for fixing the rings 8 on the legs 2.

Устройство работает следующим образом.The device operates as follows.

Захватное устройство опускают грузоподъемным механизмом и заводят под— хватные лапы 2 под груз. При этом благодаря взаимодействию ограничительных упоров 7 с горизонтальной частью траверсы 1 лапы 2 сохраняют горизонтальное положение. Затем концы ветвей • 3 ' ......._ _ стропа с помощью колеа 8 закрепляют на лапах 2 с упррами 9, обеспечивающими надежное крепление колец 8 на лапах 2.The gripping device is lowered by a hoisting mechanism and is brought under the gripping legs 2 under the load. In this case, due to the interaction of the limit stops 7 with the horizontal part of the yoke 1 legs 2 maintain a horizontal position. Then the ends of the branches • 3 '......._ _ slings with a track 8 are fixed on the legs 2 with stoppers 9, providing reliable fastening of the rings 8 on the legs 2.

При освобождении устройства от груза кольца 8 отсоединяют от лап 2 и последние выводят из-под груза.When the device is released from the load, the rings 8 are disconnected from the legs 2 and the latter are removed from the load.

Claims

FIELD OF THE INVENTION The invention relates to lifting equipment, namely to gripping devices. Known gripping device containing the l-shaped traverse with two podkvatnymi legs and sling suspension Ij. The disadvantage of it is the lack of reliability of the possibility of the load falling from the pick-up legs. The purpose of the invention is to increase the reliability of operation by preventing the load from dropping from the catch legs. This goal is achieved by the fact that in the horizontal part of the L-shaped cross bar there are holes through which only one branch line is passed under the weights provided with restrictive stops that interact with the L-shaped cross bar and rings that are worn on the lifting legs, and also that paws are provided with stops for fixing rings on them. FIG. 1 shows schematically the proposed gripping device, general view; in fig. 2 - the same side view. The device contains an L-shaped yoke 1 with two lifting paws 2 and a sling suspension, including four branches connected by a common earring 3, a sling, two of which 4 are fixed in the upper part of the yoke 1, and the other two 5 are passed through holes 6 made in the horizontal part of the crosspiece 1, and provided with restrictive stops 7 and rings 8 at the ends for the legs 2. While the legs 2 are provided with stops 9 for fixing the rings 8 on the legs 2. The device operates as follows. The pick-up device is lowered by a lifting mechanism and winding the lifting legs 2 for load. At the same time, due to the interaction of the restrictive stops 7 with the horizontal part, the crossheads 1 of the leg 2 retain their horizontal position. Then the end of the branches 5 of the sling with the help of the track 8 is fixed on the paws 2 with the elastic 9, ensuring reliable fastening of the rings 8 on the paw paw 2. When the device is released from the load, the rings 8 are disconnected from the paws 2 and the latter removed from the load. Claim 1. Grabbing device containing an L-shaped traverse with two paw legs and a sling suspension, characterized in that, in order to increase the reliability of the work by preventing the load from falling down from the paws, in the horizontal part of the G-shaped traverse, holes are made through which are missing some branches of the sling suspension, equipped with restrictive stops, interacting with the L-shaped cross member and rings, put on the lifting legs.

2. A device according to claim 1, characterized in that the pick-up legs are provided with stops for fixing the rings on them. Sources of information taken into account in the examination 1. USSR author's certificate N9 6.3969, cl. 358 6/02, 1944 (prototype) ..
