Description

The invention relates to industrial transport, in particular, to stacker cranes.

Known cargo capture of the crane - stacker, containing a frame including a beam, on which are fixed forks and cheeks, road wheels and side rollers [1].

A disadvantage of the known device is the complexity of the design, due to the fact that the column must have special machined guides along which ка four rollers are mounted, fixed on the cheeks,. „Which must be precisely installed relative to the rails, since“ they may jam.

The purpose of the invention is to increase the rigidity of the frame.

This is achieved by the fact that in the proposed device, the cheeks are interconnected by two couplers displaced relative to each other in the vertical and horizontal planes, and the track rollers are mounted on these couplers, one on each, and are made with a groove.

In FIG. 1 shows a stacker crane with the proposed cargo grab, 30 front view; in FIG. 2 - the same side view; in FIG. 3 - cargo capture (node I in Fig. 2); on the. FIG. 4 something. same. side view; in FIG. 5 - same, top view; in FIG. 6 - track roller (section AA. Fig. 5); in FIG. 7 and 8 - types of columns of the crane stacker; in FIG. 9 - side roller (section B — B of Fig. 4).

The cargo capture 1 is mounted on a rectangular column 2 connected by a flange to a rotary platform 3 mounted on the frame of the trolley. 4, carrying a lead 5-7 of lifting, turning and moving the trolley along the bridge 8, moved by the drive 9 along the path 10. The stacker crane is controlled from the pendant 11. The cargo grab (see Fig. 3-5) consists of a frame 12, representing two cheeks 13 connected by traverses 14, which are connected by plates 15. An axis 16 is installed in the holes of the plates. Forks 17 are moved along the axis 16, fixed by a screw 18. The cheeks 13 are connected by couplers 19, two of which are located on opposite sides of the column are simultaneously the axes of the track rollers 20, made with a groove

and having two contact points of contact with the plane of the column.

Four side rollers 21 are mounted in the holes of the cheeks and are fixed in the housing 22. The axis of the couplers 19 is offset in the vertical and horizontal planes. Attached to the upper traverse 14; housing 23 of the cable block 24.>

'Cargo capture works as follows.'

The load acting on the forks 17 creates a tipping moment relative to the axis of the block 24, which is perceived by the track rollers 20 mounted on the couplers 19 connecting the cheeks 13, thereby increasing their rigidity.

This design of the location and fastening of the support rollers of the cargo gripper allows the use of a column of rectangular, square profile (see Fig. 5), welded from two channels (see Fig. 7), or from an I-beam (see Fig. 8) without guides and additional machining ·, which reduces the complexity of the manufacture of the column.

The use of screeds 19 and two track rollers 20 instead of four or eight track rollers in known designs of cargo grippers can increase the rigidity of the frame,

- to simplify the design and assembly and reduce the complexity of manufacturing ^e.

Claims (1)

(54) CARGO CAPTURE OF STACKER CRANE and having two contact points of contact with the plane of the column. Four side rollers 21 are fixed in the slot of the cheeks, fixed in the housing 22. The axes of the strut 1 are displaced in the vertical and horizontal planes. The upper traverse 14 is attached with; case 23 of the rope block 24. l. Cargo capture works in the following way. The load acting on the forks 17 creates a tilting moment about the axis of the block 24, which is perceived by the support rollers 20 mounted on the straps 19 connecting the cheeks 13, thereby increasing their rigidity. This design of the positioning and fastening of the load-carrying road wheels allows the use of a rectangular, square profile column (see Fig. 5), welded from two channels (see Fig. 7), or from an I-beam (see Fig. 8) without guides and additional mechanical treatment, which reduces the labor intensity of manufacturing the column. 77 /777/7,7777//.77/////////////////////////// ///////// Application of the articles 19 and two supporting rollers 20, instead of four or eight supporting rollers in the known designs of the load grippers, allows to increase the rigidity of the frame, simplify the design and installation and reduce the labor intensity of manufacturing. Claims of the invention The cargo grip of an articulated crane, comprising a frame including a cross bar on which the forks and cheeks are mounted, support rollers and side rollers, characterized in that, in order to increase the rigidity of the frame, the cheeks are interconnected displaced one relative to another in vertical and horizontal planes with two straps, and support rollers are mounted on these straps, one for each, and made with a groove.
