Description

The invention relates to a lifting machinery, in particular to grippers for containers with trunnions,

The purpose of the invention is to simplify the design.

FIG. 1 shows the tilting device, general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 is a view A of FIG. 1, when canting (unloading); FIG. 5 is a section B-B in FIG. 2; in fig. 6 - section G-Y in FIG. 2

The gripper-turner for containers with pins contains a carrier yoke 1 with vertical posts 2, in which grooves 3 are made. In the grooves of 3 supports the yoke with the help of semi-axes 4 a gripping body 5 is installed, made in the form of a horizontal U-shaped bracket. In the gripping body 5 is made on both sides of the catcher 6 in the form of horizontal grooves. Catchers 6 have bevels 7 for better orientation of the gripping body 5 in the process of gripping the container 8 with pins 9. When the container 8 is seized, the gripping body 5 of the pins of the 9-container 8 enter the grooves of the catcher 6. When the container 8 is fully gripped by the gripping body 5, the container 8 stops a device for fixing the container in the gripping body, made, for example, in the form of a stopper 10 with a spring and turning the tongue 11. In the container 8 for locking in the gripping body, stops with 12 holes are provided. On the semi-axis x 4 of the gripping body 5, the tilting blocks 13 and 14 are rigidly mounted on both sides. These blocks are connected to the carrier cross member 1 by means of flexible links 15, for example, ropes of equal length, which envelope the blocks from the side coinciding with the direction of the tipping of the grip with the container .

The center of mass of the gripping body with the container (Fig. 2 and Fig. 3, t.t.) is offset relative to the semi-axes 4.

The mechanism of fixation of the gripping body 5 relative to the bearing cross member 1 is made in the form of a stopper 16 pivotally connected to the stand 2 of the bearing cross member 1, and

stops 17 and 18, made on the gripping body 5. In this case, the stop 18 from the side of the stopper 16 has a hook 19 in the form of a tooth, which interacts in the initial position with the stopper 16. The stopper 16 is spring-loaded spring 20 down to the stop in the stop 21, made on the rack 2. When unloading the container, the stopper 16 is actuated and disengaged from the engagement with the hook 19.

On the canting block 14, for example, on the outer flange there is a protrusion 22 for interacting with the stopper 16 and locking the gripping member 5 with the container 8 when tilted in the unloading position (Fig. 4).

In the lower part of the grooves of the catcher 6, samples 23 are made under the pins 9 of the container 8 in a fixed position. When lifting the traverse 1 with container 8 up

pins 9 of the container are lowered into samples 23 and are supported on the gripping body 5.

When tilting the gripping body 5 with the container 8 when unloading, in addition to rotating the container along with the gripping

the body also moves the container 8 relative to the gripping body 5 downwards, a blow occurs, which facilitates emptying the container.

The peculiarity of this gripping device is that the bending blocks 13 and 14 are mounted on an x4 axis eccentric with their axis of rotation shifted relative to the contour of the block groove downwards and in the direction of tilting of the gripping body 5 (Fig. 2 and 3). The direction of the tilting of the container is shown (Fig. 2) by arrow D. The described block displacement allows maximum use of the moment from the eccentricity of the loaded gripping body 5 relative to the semi-axes for

lifting it in the grooves 3 racks 2 traverse 1 with simultaneous rotation (figure 4) when turning to unload the gripping body 5 with the container 8 and to accumulate the energy necessary for self-return of the gripping body to its original (non-tilted) position.

It is for this purpose that the length of the groove 3 of the uprights 2 corresponds to the length of the part of the corresponding flexible link 15, wound on blocks 13 and 14 during the process of tipping the gripping body 5 with the container 8.

When using a gripping device, energy is expended only on raising and lowering, and the process of turning the gripping body 5 with the container 8, i.e. their tilting and returning to the initial (non-tilted) position, occurs due to the constructive performance of the device without any expenditure of energy, due to which the power consumption during canting is reduced.

Capture-tilter works as follows.

The container 8 installed on the platform lowers the gripping device and moves the gripping body in a horizontal direction, while the pins 9 of the container 8 enter the slots of the catcher 6. The container 8 is fixed in the gripping body 5 (horizontal U-shaped bracket) with a stopper 10, into the hole of the stops 12 of the container 8.

The lifting of the gripper for the carrier bracket of the traverse 1 is carried out by a lifting device, such as a hoist. Together with the carrying head plate 1, the gripping body 5 with the container 8 mounted inside it rises. The gripping body 5 with the container 8 is fixed by the mechanism of fixation of the gripping body relative to the traverse 1 in a vertical position, while the hook 19 of the stop 18 interacts with the stopper 16. When turning the gripping body 5 with the container 8, the stopper 16 is actuated (it is turned) and disengaged from the engagement with the hook 19 of the stopper 18 of the gripping member 5.

As a result of the eccentric arrangement of the semi-axes 4, the gripping body 5 with the container 8 tilts along arrow D (Fig 2), winding the flexible links 15 into blocks 13 and 14. The flexible links 15, shortening, raise the gripping body 5 in the slots 3 of the uprights 2 bearing traverse 1 and at the same time turn it. As a result, the gripping body 5 with the container 8 occupies the position shown in FIG. 4.

In this position, the stopper 16 interacts with the protrusion 22 of the turning unit 14, and the gripping body 5 with the container 8 is fixed in the upturned position

(Fig, 4). In the upturned position, the container 8 is moved downwards relative to the gripping body 5. In this case, the pins 9 of the container 8 are in contact with the upper part of the slots of the catchers 6, a blow occurs that

facilitates emptying of the container.

To return the gripping body 5 with the container 8 to the initial (non-tilted) position, the stopper 16 is actuated, which, when rotated, is released from the engagement with the protrusion 22 of the block 14, and the gripping body 5 with the container 8 is lowered into the grooves of the 3 supports of the traverse due to its own weight 1 while simultaneously rotating it from the moment created by the flexible links 15 on

turning the blocks 13 and 14. This moment returns the gripping body 5 with the container to its original position (figure 2).

The stopper 16 in this case interacts with the hook 19 of the stop 18, fixing

gripping body 5 with container 8 in the initial position. Capture-tilter with empty container lowered, set the container on the ground. Press on the stopper 10 vertically install the tongue 11 and remove the stopper 10 from the holes of the lugs 12 of the container 8.

When the container 8 is lowered onto the platform, the journal 9 moves to the upper part of the groove of the catcher 6 of the gripping body 5,

Moving the yoke 2 gripper in a horizontal direction, deduces the pins 9 of the container 8 from the grooves of the catcher 6 of the gripping organ.

When canting the next container

with trunnions, the operation of the device is repeated.
