one

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, in particular, to devices for reducing the swinging of a load gripping body with a load suspended on a cargo compartment.

A device is known for reducing the swinging of a load gripping body with a load suspended on a load trolley, containing restrictive flexible rods connected to a supporting element for a load gripping body and wound on drums installed with the possibility of turning, hanging on a support node around its axis and connecting mechanical transfer with drive vrash.ei, while the restrictive flexible gigabytes are connected by means of a synchronizing mechanical transmission with a drive drum, on which the cargo pendant 1 is wound.

A disadvantage of the known device is the low reliability of operation and the large amplitude of the load swing.

The purpose of the invention is to increase the reliability of the device and reduce the amplitude of the buildup of the load.

The goal is achieved by the fact that in a device for reducing rocking

5 rotatably on a support node around its axis and connected with a mechanical transmission with a drive for their rotation, while the restrictive flexible rods are connected by means of a synchronizing mechanical transmission mechanism with a driving drum, on which the cargo pendant is wound, the restrictive flexible rods contain two a pair of one-sided bending chains, the supporting element for the load gripping body contains a flat frame in the form of a four-sided square, and the supporting unit contains an additional frame, reinforced by rigid connections p d trolley body, the reels on which are wound restrictive flexible rods are mounted on the same axis in pairs, are provided with covering their casings, made with the guide input channels, and mounted under the trolley body, the ends of the guide input channels reinforced with an extra

the frame, the mechanical gear contains a group of gears, driven from which are fixed to the drums, and the synchronizing mechanical gear contains gearsH rigidly mounted on the axis of rotation of the drive drum for the cargo puck, and the chains passed through the guiding inlets of the covers are matched with gears m and fixed at its ends on a flat frame at its corners, the peripheral drums are mounted for rotation in the direction opposite to the side of rotation of the internal drums, and the ends on ravl constituent input channels each adjacent housings to each other drums. They are scattered on both sides of the vertical plane passing through the axis of rotation of the oraban.

FIG. 1 shows the device, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the device, generally view in axonometric projection; in fig. 4-node I in FIG. 3

The device is mounted on a cargo trolley comprising a plate 1 (Fig. 1 and 2) of the body, placed in plate 2 (Fig. 1) mounted on rollers 3 mounted on transverse beams 4, highlighted on rollers 5 moving along rails 6.

The shield 1 of the body of the load truck is driven in rotation from the drive 7, and a lifting device and an anti-jump device are mounted on it.

The lifting device includes a cargo boom 8 (Fig. 1-3), pivotally mounted on brackets 9 (Fig. 1), which are fixedly mounted on the plate 1 (Fig. 1).

The lower part of the cargo boom is a toothed sector that is in external engagement with the driving gears 10 (Fig. 1), driven by the engine 11 (Fig. 2).

The boom is equipped with three blocks 12-14 (fig. 2), along which the cargo pendant 15 (fig. 1 and 3) passes with a load gripping body 16 fixed at one end (fig. 1 and 3). The other end of the load pendant is attached to the drive drum 17 (Fig. 2 and 3) fixedly mounted on the same axis together with the gears 18 of the synchronizing mechanical transmission (Figs. 1 and 3), which engage with the connecting fingers 19 (Fig. 1 -4) chains 20 (figs. 1 and 3) of restrictive flexible threads included in the device for reducing the swinging of the load gripping organ, which contains four cartridges, each of which includes a drum 21 (fig. 2) fixedly connected to the driven gear 22 mechanical transmissions (FIG. I-3) and housing 23, pkva yvayuschy drum 21 and configured inlet-tube 24 of rectangular section

(Fig. 1.3) for the entrance of the circuit 20 (Fig. 1 and 3). The housing 23 serves to house a chain mounted on the drum 21 (FIG. 2). On each of the four drums 21 (Fig. 2), one chain 20 is fixed (Figs. 1 and 3). Drums 21, which are integral with the gear wheels 22, are freely placed on a common axis 25 (Figs. 2 and 3), fixedly fixed in the axles 26 (Fig. 1 and 3), which are rigidly connected to the plate 1

P hull cargo trolley (Fig. 1 and 3) and serve as the main support of anti-skidding device. The lower ends a of the chains 20 (Figs. 1, 3 and 4) are rigidly embedded in a flat frame 27 (Figs. 1 and 3), a support element for the load gripping body, which is pivotally connected to the load gripping body 16 (Fig. 1 and 3). The frame 27 has the shape of a quadrangle, while the lower ends a of the chains 20 located at its corners of the b chains 20 are one-sidedly bent. The ends of the guiding inlet cavals 24 of the covers of each pair of adjacent drums 21 are located on either side of the vertical plane passing through the axis 25 of the rotation of the drums. On axis 25 (Figs. 2 and 3), all four shells 23 are fixed but fixed (Fig. 3). and the inlet channels-pipes 24 (Fig. 1 and 3), which are a continuation of the covers, are rigidly embedded in an additional frame 28 of the support assembly (Fig. 1 and 3), which is fixedly connected to the plate 1 (Figs. 1 and 3)

0 by means of squares 29 (Fig. 1 and 3). Driven gears 22 (fig. 1-3), through mechanical transmission group 30-33 (figs 1 and 2), fixedly mounted on axles 34 and 35 (fig. 2), engage

5 with a drive bristle 36 (FIG. 1 and 2) of the engine 37 (FIG. 2). The gear system 30-33 (FIG. 1-3) is designed to rotate the inner pair of gear wheels 22 (FIG. 1-3) in the direction opposite to the rotation of the peripheral pair of gears

0 wheels 22 (fig. 1-3). On the grip-catching body 16 placed load 38.

The device works as follows.

When lifted by lifting body 16

(Fig. 3) the load 38 (Fig. 1 and 3) is included

j to lift the engine 37 (Fig. 2), and through the system of gears 36, 33, 32, 31 and 30 (Figs. 1 and 2), the gears 22 (Fig. 1-3) with the drums 21 (Fig. 1) begin to rotate. 2), on which chains 20 are fastened with their ends (Figs. 1, 3 and 4). As a result, chains 20 (Figs. 1, 3 and 4) are drawn into pipes 24 (Figs. 1 and 3) and placed on drums 21 (Figs. 2). In this case, two chains 20 (Figs. 1, 3 and 4), which, with their connecting fingers 19 (Figs. 1, 3 and 4), engage with gears 18 of the synchronizing mechanical transmission (Figs. 1 and 3), result in rotation still fixed on the same axis with them drum 17 (Fig. 2 and 3). with the end of the cargo -o-pendant attached to it, and the load 38 with a load gripping ramp 16, mounted on the other end of the load pendant, rises to the place of installation. The collapse (the load is prevented by the structure consisting of four chains 20 (Fig. I and 3). One pair of these chains which are engaged with gears 18 (Figs. 1 and 3) can be bent separately in the direction of opposite to the other possible pair of chains, but in view of the fact that the lower ends of all four chains are rigidly embedded at the corners of the quadrangular frame 27 (Fig. 1 and 3j, and the upper ends of the chains enter the pipe-channels 24 (Fig. 1 and 3), rigidly embedded in frame 28 (figs. 1 and 3), the structure as a whole is a rigid rod, which, being connected to It prevents the load from swaying from external influences.The proposed device has an increased reliability in operation.
