Description

Изобретение относится к подъемнотранспортной технике, в частности к гидравлическим грейферам.The invention relates to hoisting equipment, in particular to hydraulic grabs.

Известен грейфер гидравлический, содержащий корпус с челюстям, привод челюстей, упор, шарнирно соединенный с гидро цилиндром и с корпусом посредством кронштейна Γΐ].A hydraulic grapple is known, comprising a housing with jaws, a jaw drive, an emphasis pivotally connected to the hydraulic cylinder and to the housing via the bracket Γΐ].

Однако в данном грейфере не обеспечивается поворот груза в вертикальной плоскости^ что является обязательной технологической операцией.However, this grapple does not provide for the rotation of the load in the vertical plane ^ which is a mandatory technological operation.

Цель изобретения - расширение эксплуатационных возможностей.The purpose of the invention is the expansion of operational capabilities.

Для достижения этой цели гидроцилиндр установлен, вертикально, упор снабжен шарнирно соединенными с ним тяга Бли, а крошнтейн - направляющими для тяг.To achieve this goal, the hydraulic cylinder is installed vertically, the emphasis is equipped with a blea rod pivotally connected to it, and the crust rod has guides for rods.

На фиг. I - изображен грейфер, фронтальная проекция; на фиг. 2 - то же, ю боковая проекция; на фиг. 3 - вид А на фиг. 2.In FIG. I - shows a grab, frontal projection; in FIG. 2 - same, th side projection; in FIG. 3 is a view A in FIG. 2.

Грейфер содержит корпус I, челюсти 2, стержни 3 и гидроцилиндр 4. Корпус >The grab contains a housing I, a jaw 2, rods 3 and a hydraulic cylinder 4. Housing>

имеет кронштейн 5, с которым жестко соединен гидроцилиндр 6, на конце штока 7 которого шарнирно закреплен упор 8. Для предотвращения поворота и упора 8 со штоком 7 гидроцилиндра имеются тяги 9, один конец которых шарнирно закреплен на оси упора, а второй конец установлен в направляющих 10 кронштейна 5 с возможностью возвратно-поступательного перемещения.has a bracket 5 with which the hydraulic cylinder 6 is rigidly connected, at the end of the rod 7 of which the stop 8 is pivotally fixed. To prevent rotation and stop 8, there are rods 9 with the rod 7 of the hydraulic cylinder, one end of which is pivotally mounted on the axis of the stop, and the other end is mounted in guides 10 of the bracket 5 with the possibility of reciprocating movement.

Грейфер работает следующим образом.The grab works as follows.

Стрелой погрузочной машины устройство подводится к уложенным в штабель .деревям. При этом челюсти 2 открыты, а упор 8 поднят гидроцилиндром 6 в верхнее положение. При подаче жидкости в штоковую полость гидроцилиндра 4 челюсти 2 грейфера закрываются, захватывая пачку деревьев. При этом стволы деревьев прижимаются к упору 8. Далее устройство с зажатой дачкой деревьев подводят погрузочной машиной к. лесовозу. При подаче жидкости в поршневую полость гидроцилиндра 6 упор 8 опускается, пово3 речивая пачку деревьев в вертикальной плоскости. Такой прием (поворот пачки деревьев в вертикальной плоскости при погрузке деревьев в лесовозный транспорт) , позволяет на 2-3 м снизить высоту подъема стрелы погрузчика, так, как преодоление высоты пакета деревьев, уложенных на коники лесовоза, осуществляется путем подъема вершины деревьев за счет /поворота всего?его дерева в вертикальной плоскости.With the arrow of a loading machine, the device is led to stacked trees. In this case, the jaw 2 is open, and the emphasis 8 is raised by the hydraulic cylinder 6 to the upper position. When liquid is supplied to the rod cavity of the hydraulic cylinder 4, the jaw 2 of the grab closes, capturing a pack of trees. In this case, the tree trunks are pressed against the stop 8. Next, the device with a clamped summer cottage bring a loading machine to the timber truck. When fluid is supplied to the piston cavity of the hydraulic cylinder 6, the support 8 is lowered, turning the stack of trees in a vertical plane. This technique (turning a stack of trees in a vertical plane when loading trees into a timber transport vehicle) allows reducing the lift height of the loader by 2–3 m, since overcoming the height of a package of trees laid on the cones of a timber truck is carried out by lifting the top of the trees by turning everything? its tree in a vertical plane.

Claims

The invention relates to lifting machinery, in particular to hydraulic grabs. A hydraulic grab is known, which contains a jaw body, a jaw drive, an emphasis pivotally connected to a hydraulic cylinder and a body by means of a flj bracket. However, this grab does not provide for rotation of the load in a vertical plane, which is a mandatory technological operation. The purpose of the invention is the expansion of operational capabilities. In order to achieve this goal, the hydraulic cylinder is installed, vertically, the emphasis of the sleep of the wrist arms connected with it, and the white wire — by the guides of the cylinder. In FIG. I - depicts a grab, frontal projection; in fig. 2 - the same side view; in fig. 3 is a view A of FIG.

2. The grapple includes a body t, a jaws of the rods 3 and a hydraulic cylinder 4. The body has a bracket 5 with which the hydraulic cylinder .6 is rigidly connected, and the stop 8 is hinged at the end of the stem 7. To prevent rotation and stop 8 with the hydraulic cylinder rod 7, there are drawbars 9, one end of which is hingedly mounted on the axis of the stop, and the other end is mounted in the guides of the bracket 5 with the possibility of reciprocating movement. Grab. Works as follows. The device of the loading machine jib is brought to the wooden trees placed in the stack. At the same time, the jaws 2 are open and the stop 8 is raised by the hydraulic cylinder 6 to the upper position. When fluid is supplied to the rod end of the hydraulic cylinder, 4 jaws 2 of the grapple are closed, grabbing a pack of trees. At the same time, the trunks of the trees are pressed against the stop 8. Next, the device with the clamped Ifachka of trees is brought by a loading machine to the timber carrying vessel. When fluid is supplied to the piston cavity, the hydraulic rod 6, the stop 8 is lowered, turning the pack of trees in a vertical plane. Such a technique (rotation of a bundle of trees in a vertical plane when loading trees into a forest transport) allows to reduce the lifting height of the loader arm by 2-3 m. Sak overcoming the height of the package of trees laid on the horses of a timber truck is carried out by lifting the tops of the trees by turning everything: its tree in a vertical plane. The proposed grab extends the technological capabilities of the machine, increases the loading performance and is characterized by simplicity of design. Invention formula The hydraulic grab, comprising a jaw body, jaw drive, stop, pivotally connected with a hydro-lindre and with a housing by means of a bracket, characterized in that operational capabilities, the hydro-pilot is installed vertically, the support is equipped with articulated joints with them, and the bracket guides for t.
