Description

CAPACITY BARREL.

The invention relates to fuso-gripping mechanisms hung on a crane hook, in particular to barrels.

Known end grip for barrels containing traction, equipped with a gripping body in the form of a strap and a pivotally connected lever provided with a single sponge. The lever is equipped with a ring that is hung on a lifting hook.

mechanism. The end grip is used mainly for lifting barrels lying on the floor and requires the direct participation of US RU Patent No. 2020121 В 66С

A load-gripping device is known, comprising a housing with a through vertical groove, gripping arms pivotally mounted on the housing, an eye for attaching the mechanism to the crane hook, an axis made integrally with ratchet, a dog articulated on the housing, a locking cam rigidly mounted on the axis and a spring-loaded lock position of the locking cam.

In the initial position, the major axis of the locking cam is in the vertical position. When lowering the hitch, the load exerts pressure on the bevels of the gripping levers that move apart and the thickening of the load is in the cavity between the shoulders of the gripping levers. With further lowering, the axis lowers to the bottom of the groove. In this case, from the interaction of the ratchet and the dog, the axis rotates and with it the locking cam 90 ° and the cam axis is in a horizontal position. During the subsequent lifting, the gripping levers due to the interaction of their shoulders with the upper plane of the cam do not have the ability to rotate and the load is captured.

The design flaws include the large free travel of the gripping levers, the complexity of the cam mechanism design.

The objective of the invention is to develop a fuso-capture device that allows for reliable remote capture of cargo, which are barrels of radioactive waste. To move such a body, a reliable lifting device is required to prevent the body from swinging.

providing a small free run of the flies during the capture and release of the cargo due to insufficient space in the storage of radioactive waste. The objective of the invention is solved as follows.

The lifting device for barrels is a housing made in the form of a fixed cylindrical tubular element, with three branches of the linkage mechanism rigidly attached to it. In the central part of the body there are through vertical grooves. A movable cylindrical tubular element of smaller diameter with a vertical slot is installed inside the housing, while the movable element is arranged to move in a vertical plane. A latch is mounted on the movable element and three elements are fixed for hinging three gripping levers, which are pivotally connected to the branches of the linkage mechanism. An eye is attached to the upper end part of the movable cylindrical tubular element, and the cam is rotatable and spring-loaded and located on an axis inside the stationary cylindrical element.

In FIG. 1 schematically shows a device in section. Figure 2 schematically shows the appearance of the device and section AA

The device comprises a fixed tubular element 1 (device body) with through vertical grooves 10 (Fig 2) in the middle part for moving the elements 5 mounted on the movable tubular element 2 (Fig 1). Inside the housing 1 there is a movable cylindrical tubular element 2 with three elements fixed on it 5. Gripping arms with shoulders 8 are attached to the elements 5. Ulor 4 is fixedly mounted in the movable pipe 2. (Fig 1) An eye 6 is connected from above to the movable pipe for hanging on hook fuso-lifting me) (anism.

Three branches of the linkage mechanism 9 are welded to the fixed tubular element (FIG. 1, 2), by which the fusolock device is mounted on the barrel.

In the fixed tubular element on the axis there is a rotary cam 7 (Fig 1) of the locking mechanism, made spring-loaded (Section AA), rotationally driven alternately by an emphasis 4 and a vertical slot 3 of the movable tubular element 2. To prevent. spontaneous rotation of the cam on the axis is spring-loaded with a spring 12 The cam is rotatable and is a locking mechanism by which the fuso-gripping device is fixed in two positions: A - open for installation on the barrel and removal from the barrel; B - closed - for lifting the barrel. (See FIG. 2) The device operates as follows.

The movable tubular element 2 rises through the eyelet. At the same time, the cam 7 of the fixed tubular element is in a position in which the gripping levers are in a unlocked and locked position. The cam with its lower protrusion is the wall of the movable pipe, which makes it possible to raise the gripper in a raked position and install it on the barrel or remove it from it. After installing the fixed tubular element 1 on the barrel, the movable element 2 with the emphasis 4 falls down under the action of its own weight, while the slot 3 of the movable pipe releases the cam from the locked position and allows the emphasis to rotate it in the slots along the rotation path by 20-25 ° . When the elements 5 rest on the edge of the slot on the fixed pipe, the gripper takes a neutral position A. Then, when lifting the movable pipe 2 attached to the eye, the movable pipe rotates the cam 7 further with the lower edge of its slot, the elements 5 rise upward and when the fixed branches of the lever mechanism 9 interact and gripping levers 8, the barrel 11 is gripped (Position B).

When installing the barrel on the surface, the fixed part of the fuso-grip rests on the barrel, then, under the influence of its own weight, the movable tubular element is lowered and the cam rotates by an emphasis of 20-25 °. At the same time, the gripping arms release the barrel. And then, when lifting the movable pipe, it rotates the cam to the locking position with the lower edge of its slot. T.O. the fuso-gripping device becomes in the open position A.

Thus, the fuso-capture device is a three-lever self-centering, self-locking and self-locking fuso-gripping device that ensures the reliability of the capture and uncoupling of barrels when remotely controlling all operations, which is especially important for working with radioactive waste.
