STAND TO STUDY CABLE TWISTING PROCESS Russian patent published in 2008 - IPC G01B5/00 D07B3/08 

FIELD: mechanics.

SUBSTANCE: invention relates to lifting and transportation machinery production, in particular, to steel cables and aims at analysing the production process effects on the steel cable quality, specifically, to analysing the influence of irregular tension of the wires (strands) on irregularity of the lengths of wires (strands) of the steel cable. The stand, as per given invention, to study the cable twisting process incorporates a frame made as drift structure has a single beam accommodating at its centre a clamp with strands of the cable to be twisted. The frame two vertical supports are made in the form of a lead screw with two nuts-gears arranged thereon and engaging a gear wheel. The said wheel is arranged so that it can run around a clamping sleeve rigidly fixed at the centre of movable carriage supported, via bearings, by the said nuts-gears. A strand outer layer distribution template is fixed to the gear wheel hub lower part, the strand inner layer distribution template is attached to the above template to run around a vertical axis. A carrier with two pulleys-satellites is attached to the hear wheel hub side surface. One of the pulleys-satellites is coupled via belt transmission with the clamping sleeve, while the other one gets connected to the inner layer distribution template. The carrier is provided with a drive engaging the gear wheel. The strands of the cable twisted are connected by their upper ends the clamp, are passed through the clamping sleeve with and appropriate holes of distribution templates, their lower ends being connected to the tension weights. There is a possibility of simulation of the two-layer cable twisting process without ruling out a gravity-type tension device from the process.

EFFECT: possibility of simulation of the two-layer cable twisting process without ruling out a gravity-type tension device from the process.
