SU24300A1 - A device for balancing variable loads on a hook, serving to support the blanks during their forging - Google Patents

Description

The invention relates to devices for balancing variable loads on a hook, serving to support the blanks during their forging. In the proposed device, a counterweight is applied, composed of a vertical row of plates, each resting on the benches of the shaft in which the plates are enclosed, and being gripped successively one after another with an increase in hook load.

In FIG. 1 is a side view of the device; FIG. 2 is a cross-section of the plates and the platform in which they are enclosed; FIG. 3-view of the mine and slabs from above.

A hook 12 serving to support the pigs during their forging is supported by a hook 10 connected to the cable 1 slung over the blocks 11. A hook 8 is connected to the hook 12 by means of a coil spring 9 by means of which the worker supports the hook with the hook during work . The cable 1 connected to the hook 10 is lowered into the shaft 16 (Fig. 1-3), provided with ledges b, on which the slabs 3 located in the mine rest. The dimensions of the plates are reduced successively from the top to the bottom, with the bottom of them being directly connected with cable 1, and the rest is free on. D.

children on this cable. In order to avoid the plates moving to the side, the rods 2 pass through them, which serve as guides during the vertical displacements of the plates. As the load on the hook 12 increases, the latter puts pressure on the hook 10 and, through it, pulls the cable 1, at which the cable moves and grips the plates successively one after another in the direction from the lower to the upper ones, as a result of which the plates serve as a counterweight to the load on the hook and reduce the load on the handle 8.

The subject matter of the invention.

A device for balancing variable loads on a hook, serving to support the blanks during their forging, characterized by the use of a counterweight composed of a vertical row of plates of 3.3 ..., decreasing sequentially from top to bottom and enclosed in a shaft, provided with ledges supporting for said plates, of which the bottom is directly connected to the cable supporting the hook, and the rest are loosely attached to this cable and are captured as the load increases successively one after another in the direction from izhnih to the top. to the author's testimony of M.
