.Изобретение относитс к канаткому производству, в частности, к технологии предварительной выт жки канатов.The invention relates to rope production, in particular, to the technology of pre-stretching of the ropes.

По основному авт. св. № 479842 известно устройство дл предварительной выт жки канатов, содержащее установленные на станине и кинематически св занные между собой подающий механизм и выт жной механизм, выполненный в виде тормозного и нат жного барабанов и шкивов, а также ванну дл смазки и канатоукладчик. Шкивы смонтированы с возможностью свободного вращени и их оси параллельны ос м барабанов, причем один шкив размещен между нат жным барабаном и ванной дл смазки 1 WAccording to the main author. St. No. 479842, a device for pre-stretching of ropes, comprising a feeding mechanism mounted on a frame and kinematically interconnected, and a pulling mechanism made in the form of brake and tension drums and pulleys, as well as a lubricant bath and a cable laying machine. The pulleys are mounted for free rotation and their axes are parallel to the axis of the drums, with one pulley being placed between the tension drum and the 1 W lubrication bath

Недостатком устройства вл етс его низка т гова способность и обусловленна этим невозможность осуществлени качественной обт жки канатов .The disadvantage of the device is its low traction ability and the consequent impossibility of carrying out high-quality wrapping of the ropes.

Цель изобретени - повышение т говой способности, устройства.The purpose of the invention is to increase the traction capacity of the device.

Указанна цель достигаетс тем, что в предложенном устройстве шкивьа установлены с возможностью регулировочного возвратно-поступательного перемещени параллельно оси подачи каната , при этом шкивы и барабаны снабжены жестко закрепленными на их торцах зубчатыми венцами, св занныкп между собой попарно.This goal is achieved by the fact that, in the proposed device, the pulleys are installed with the possibility of adjusting the reciprocating movement parallel to the rope feed axis, while the pulleys and drums are provided with gear rings rigidly attached to their ends connected in pairs.

Устройство снабжено двум шестерн ми , кажда из которых установлена между зубчатыми венцами шкива и соответствукидего ему барабана.The device is equipped with two gears, each of which is installed between the toothed rims of the pulley and its corresponding drum.

Между йатушкой 1, с которой сма0 тываетс канат 2 и приемным механизмом 3, на который наматываетс выт нутый канат, размещаютс нат жной барабан 4 с электродвигателем 5 и тормозной барабан б с электродвига:5 телем 7 электродинамического торможени . Катушка 1, приемцый механизм 3, а также нат жной и тормозной бара баны 4 и 6 с электродвигател ми 5 и 7 стационарно размещены на станине A tension drum 4 with an electric motor 5 and a brake drum with an electric motor: 5 with an electrodynamic braking device 7 are placed between the yatushka 1, from which the rope 2 is being washed and the receiving mechanism 3, onto which the drawn rope is coiled. The coil 1, the receiving mechanism 3, as well as the tension and brake bars 4 and 6 with electric motors 5 and 7 are permanently placed on the frame

Claims

0 8. A pulley 10 is placed between the tension drum 4 and the lubrication bath 9, and a second pulley 11 is placed symmetrically with respect to the drum b. Both pulleys are mounted relative to the base 8 with the possibility of longitudinal movement and are equipped with units 12 for fixing relative to the base. The pulleys and drums are provided with toothed rims 13, therefore, they are brought into engagement directly with each other (in the case of a crisp rope stanchion) or through a detachable inventory pole 14 (in the case of an oval-strut rope strut). The device works as follows. Rope 2 from feed coil 1 (Fig. 1) oval-shaped (Fig. 3) is stored on brake drum b and pulley 11, which are kinematically connected to each other using gear gear 14. Next, the rope is oval-shaped stored on pulley 10 and drum 4, connected by gear 14, and being passed through a bath 9 with lubricant, is wound on the receiving mechanism 3. An electric motor 5 creates on the drum 4 and a pulley 10 pulling force, while the electric motor 7 creates electrodynamic braking, providing the necessary tension on the rope at the site between drums 4 and b. In the initial position, the pulleys 10 and 11 are fixed relative to the bed 8 by nodes 12. To move to the cruciform rope, the removable gears 14 are removed, the nodes 12 are loosened, the pulleys 10 and 11 are displaced in the longitudinal direction, and the gear rims 13 are engaged with the f J3 13 11 X ///. // with the drums 4 and b. Sites of this by knots 12 pulleys ts I stopper relative to frame 8. Rope 2 from feed roller 1 (fig. 2) is cross-shaped (fig. 4) on pulleys and drums first brake, then tension sections and then on receiving mechanism 3. Exhaust technology is similar. The proposed device makes it possible to increase the pulling capacity by 2 or 4 times (respectively, with an oval-shaped and cruciform cage rope). Claims 1. Device for pre-stretching of ropes according to ed. No. 479842, characterized in that, in order to increase the traction capacity, the pulleys are installed with the possibility of adjusting the reciprocating reversal parallel to the axis of the rope feed, while the pulleys and drums are provided with gear rings interconnected in pairs .

2. A device according to claim 1, characterized in that it is provided with two gears, each of which is mounted between the toothed rims of the pulley and its corresponding drum.
