Description

This invention relates to lifting devices.

The purpose of the invention is to expand the functionality by pre-setting a predetermined angle of rotation and automatically returning the pads to their original position.

Fig „1 shows a gripper-tilter, side view; in fig. 2 - the same top view; in fig. 3 — fixation mechanism in the initial state; FIG. 4 shows a section A-A in FIG. 3j in FIG. 5 - locking mechanism in working condition.

The gripper-turner contains levers 1, at the base of which plates 2 are rigidly fixed, and rotatable plates 3 are hinged at the free ends. Lever is connected via bar 4 to rod slider 5, which has the ability to move along the cross bar, filled in the form of pipes 6. Plank 4 connected to the hydraulic cylinder 7. The turning plates 3 are rigidly connected by means of a shaft with a gear 8 located inside the lever 1 (Fig. 3, 4). The gear 8 operates with the toothed rack 9 and is connected to the lever 1 by means of a spring 10. The free end of the rack 9 interacts with the adjusting screw 11 (Fig. 5). On rail 9, there is a protrusion 12, which interacts with the retaining ring 13. Above the rail 9: on the opposite side of gear 8 there is a fixing roller 14,

When a load is moved without tilting, the load is captured by means of fixed linings 2, which are located at the base of the levers, or by means of linings 3. In this case, the load is compressed at four points and is not able to change its position relative to the levers 1 When lifting and turning the load at a certain angle (from O to 90) in the vertical plane, the grip is carried out only with the help of plates 3 located at the free ends of the levers 1. In this case, the center of gravity is displaced by some distance from the axis of rotation Dock 3. As a result, under the action of its own weight, it rotates when lifting by an angle ot relative to the horizontal and is fixed in this position by the locking mechanism.

When lifting, the load can be fully rotated and assume a vertical position.

Simultaneously with the rotation of the load, the lining 3 is also rotated, which is rigidly connected with the gear 8 by means of the shaft, which in turn interacts with the rail 9.

In the initial position, the rail 9 under the influence of the spring 10 occupies the leftmost position. The total displacement of the € 1 rails to the left is limited by the retaining ring 13 and the protrusion 12 located on it.

When the load is lifted, the gear 8 rotates with the pad 3 and moves the rail right to dock with the adjusting screw 11, as a result of which the load is fixed in the vertical plane at an angle about to the horizontal, and the spring connecting the rail with the lever expands. The angle of rotation oL is in direct linear dependence on the initial distance 1 between the rail 9 and the adjusting screw 11. If the angle of rotation is increased, the distance 1 between the rail 9 to the initial position of the screw and vice versa increases. When the lever 1 releases the load, under the influence of the spring 10, the rail 9 returns to its original position, and the gear interacting with it turns about along with the pad and also occupies the initial position. Reliable interaction between the rack and gear is provided by the roller 14.

The presence of fixed pads at the base of the levers and pivotally connected pads at their free ends allows the grip to extend its functionality. If it is necessary to carry out simple 5 handling works, the load is seized completely with the help of fixed and hinged pads.

If it is necessary to rotate the cargo in a vertical plane with its fixation at a certain angle (from 0 to 90 °) or when turning it, its grip is carried out only by pivotally pivoting lining located at the free ends of the levers.

The rotation of the load in space occurs under the influence of its own force of gravity, and the return of mezanism
