SU142192A1 - Device for the progressive periodic movement of piece goods, mainly large-sized building parts - Google Patents

Description

Devices are known that provide progressive periodic movement of axial loads, mainly large-sized building parts, consisting of directly moving by means of fist driving, which act on the levers (rocker arms), which carry the load.

A distinctive feature of the described device is that. that the swing arms pivotally mounted on the vertical uprights are made in the form of rocker arms, which are alternately successively rotated by means of lifting cams mounted on endless chains, and the firing of the load when transferring it from one lever to another is carried out by pivoting stops that interact with their tails with lowering fists. The device of this design provides a progressive periodic vertical lowering of the load.

FIG. 1 schematically depicts the described device for moving an axial load, in plan; in fig. 2 is the stand of the lowering mechanism, side view in the initial position: in FIG. 3-the same, when lifting the load by the yoke to the highest position; in fig. 4 - the same, after lowering the load on one schag; in fig. 5 - kinematic device diagram.

The device consists of four vertical pillars I, 2, 5 and (columns), the height of which is successively mounted on axles x 5 pivot arms 6 (rocker arms), carrying rollers 7 and S at their ends, as well as stops 9, which have their own shanks 10 interact with the lowering fists // located on the infinite chain 12. The stops 9 fix, the load 13 when it is transmitted sequentially with one No. 1421922

leverage on the other. The device is driven by an electric motor 14, which is h (an electric worm and bevel gearboxes / 5 and / 6 drives a lamellar non-curved chain 12. carrying two fists //).

Moving from bottom to top, the fists alternately act with their figured non-shakiness through the rollers 7 Fia of the successively mounted rocker arms. At the same time, the rocker acts on the load, removes it from the stop (see, fng. 3) and lowers it to the 11th floor and stop (see Fig. A). The rotation of the load stops for the load on the downstream stop is carried out by the interaction of the fists with the tails 10 corresponding stops with the load on the rollers 8 of the rocker arms of the lowering mechanism. After the passage of the fist and the lowering of the load on the lower end, the stops, the released rocker arms and the backs, the starting position is also established by means of the return mechanism.

In one pass from the bottom up, the sequential movement of the cargo by one tag is carried out; The lowering of the 1) coupling device occurs under the action of its own weight, while the smoothness of lowering is ensured by the drive.

The squeezable device, due to the possibility of stepwise sequential lowering of g), can be used for conrayer work.

PRIORITY AREA

A device for initiating a non-periodic movement of iggazyh goods, mainly large-sized construction parts, consisting of connected with the front-wheeling kulaks, acting on ophthalmic nodachi levers of the cargo, from the purpose of lowering the load, for the purpose of lowering the load, to move the load, to move the load. in the form of rocker arms mounted on vertical uprights) r alternately and successively turning when interacting with lifting cams fixed on endless chains, moreover for fixing the load during transmission from one arm to the other provided pivoting when interacting with their shanks onuskayun1imis fists stops.
