(54) КРАНОВЫЙ ЗАХВАТ(54) CRANE CAPTURE

II

. Изобретение относитс к подъемно-транспортному оборудованию, а именно к крановым захватам дл подъе.ма изделий, имеющих внутреннюю полость.. The invention relates to a handling equipment, namely, crane grippers for lifting items with an internal cavity.

По основному авт. св. № 457659 известен крановый захват дл подъема изделий, преи .мущественно крупных строительных плит, имеющих внутреннюю полость, содержащий коническую разрезную втулку и размещенную в ней т гу, выполненную с разжимающим участком на нижнем конце и с серьгой дл навещивани на крюк грузоподъемного механизма на верхнем конце 1.According to the main author. St. No. 457659 is known for a crane grip for lifting articles, predominantly large building slabs, having an internal cavity, containing a conical split bushing and housed therein, made with a unclamping section at the lower end and with a shackle for visiting the hook of the lifting mechanism at the upper end. one.

Недостатком известного кранового захвата вл ютс неудобство строповки и подъема издели , расположенного под больщим углом наклонаК горизонтали (така ситуаци часто встречаетс на строительных площадках ), вследствие наличи изгибающих нагрузок, действующих на т гу при ее взаимодействии с верхним торцом разрезной втулки во врем строповки и подъема издели , и неудобство эксплуатации захвата, навешенного на крюк крана, .-из-за отсутстви фи-ксации частей разрезной втулки относительно друг друга при строповке и расстроповке издели .A disadvantage of the known crane grip is the inconvenience of slinging and lifting a product located at a large angle of inclination to the horizontal (such a situation is often found on construction sites), due to the presence of bending loads acting on the yoke when it interacts with the upper end of the split bushing during slinging and lifting product, and the inconvenience of operating the grip hooked on the crane hook, due to the lack of fi-xation of the parts of the split sleeve relative to each other during slinging and stroping .

Цель изобретени - расширение области применени захвата.The purpose of the invention is to expand the scope of capture.

Цель достигаетс те.м, что т га выполнена составной из двух щарнирно соединенных между собой частей, а, по меньщей мере, одно из щарнирных соединений частей разрезной втулки снабжено фиксатором, при этом шарнирное соединение частей т ги расположено в плоскости верхнего торца разрезной втулки.The goal is achieved by the fact that the ha is made of a composite of two parts hinged together, and, at least, one of the hinged joints of the split bushing parts is provided with a retainer, while the hinged connection of the thrust parts is located in the plane of the upper end of the split bushing.

Кроме того, щарнирное соединение частей т ги выполнено шаровым.In addition, the hinged connection of the parts of the gi is made ball.

Наличие щарнира на т ге, обеспечивает строповку издели , расположенного под больщим углом нак.тона к горизонту, расположение щарнира на т ге в плоскости верхнего торца разрезной втулки исключает воздействие изгибающих нагрузок на т гу, наличие фиксатора в щарнирном соединении частей разрезной втулки- обеспечивает фиксацию частей разрезной втулки и, тем самы.м, удобство строповки и расстроповки издели ,-выполнение щарнира на т ге обеспечивает наклон т ги на необходимый угол при строповке.The presence of a hinge on the t, ensures the slinging of the product located at a large angle of inclination to the horizon, the location of the hinge on the t in the plane of the upper end of the split sleeve eliminates the impact of bending loads on the pull, the presence of a lock in the hinge joint of the parts of the split sleeve ensures fixation the parts of the split sleeve and, that is, the convenience of slinging and unraveling the product, the execution of the joint on the rod ensures tilting at the required angle when slinging.

Claims

FIG. 1 shows a crane grip when lifting the product; in fig. 2 - the same, section А-А on -fig. one; in fig. 3 shows a kinematic diagram of a crane grip when slinging a product located at a large angle of inclination to the horizon. The crane grip includes a housing made in the form of a split sleeve 1, the internal cavity of which is made in the form of a small conical surface 2 and a large conical surface 3, the upper outer surface is made conical, the bottom cylindrical with a serrated notch. The crane grip also contains a pull consisting of parts 4 and 5, a hinge 6, made by a ball, a unclenching section, made in the form of a spherical head 7, a link 8, plates 9 and 10, screws 11, bolts 12, nuts 13, thrust strips 14 and driving handles 15. Part 4 of ti is provided on the lower end with a spherical head 7, part of 5 ti is provided on the upper end of a link 8 serving to sew on a crane hook, parts 4 and 5 are connected by a hinge 6. Parts of a split sleeve 1 interconnected at the upper end of the hinge plates 9 and 10, mounted respectively on As the split sleeve 1 has screws 11 and bolts 12 with nuts 13. On the plates 9, stop bars 14 are rigidly fixed, which interact with the hexagon heads of the bolts 12 and do not allow them to rotate around their axes, and the nuts 13 are made with drive handles 15 that provide Convenience of clamping the plates 9 and 10. The thread on the bolts 12 and nuts 13 is made many-fold to provide a significant axial movement of the nut 13 when it is turned slightly, which increases the speed of fixing and releasing parts of the split sleeve 1. Crane grip works in the following way . The crane hook earring 8 is put on the crane hook and, before lifting the gripper, the parts of the split sleeve 1 are fixed in the closed position by clamping the nuts 13 by means of the driving arm of the plates 9 and 10. Then the gripper is lifted by the crane and the parts of the split sleeve 1 are resting on their small conical surface 2 the spherical head 7 and not spreading on it due to the clamping of the plates 9 and 10. The raised gripper is transferred and installed with a split sleeve 1 into the hole of the product located at a large angle of inclination to the horizon. At the same time, a part of 4 g of grip engages with a large conical surface, and a part of 5 t of g of grip due to hinge 6 is located in the direction of the cable of the crane hook. Then, by means of actuating handles 15, the plates 9 and 10 are unclenched. The product is attached by means of a crane by means of a grip, a spherical gripping head 7, in which the parts of the split sleeve 1 are disassembled due to the interaction of the spherical head 7 with a small conical surface 2 and outer a cylindrical surface with a serrated notch of the split sleeve 1 contacts the surface of the hole in the product. In this case, the hinge body 6 interacts with the upper end of the split sleeve 1 and eliminates the impact of bending loads on the crane grip. After slinging, the product is lifted and transported, in which parts 4 and 5 tons of crane grip are held upright due to the presence of a hinge 6. After installing the product, the stroping is performed as follows. A crane with a spherical head 7 is lowered down, while parts of the split sleeve 1 are closed by a hinged connection at the upper end and fixed by clamping the plates 9 and 10 with nuts 13. Then the crane grip is transferred to another product. The application of the proposed crane grip on construction sites provides slinging and lifting of products with an internal cavity, located both horizontally and at a large angle of inclination to the horizon, as well as the convenience of slinging and unraveling construction products.
