Изобретение относите: к электромонтажным приспособлени м, используемым на судах, в частности к устройствам дл зат жки кабелей.The invention relates to: electrical installation devices used on ships, in particular, devices for cable tightening.

Известно устройство дл зат жки кабелей, содержащее механизм перемещени кабел , вк.гаочающий кривошипы с ведущими и ведомьоми шестерн ми и т говые ролики, установленные на одной оси с ведомыми шестерн ми, причем кривошипы расположены по разные стороны от оси кабел llA device for cable tightening is known, comprising a cable movement mechanism, in which the cranks with leading and trailing gears and traction rollers mounted on the same axis as the driven gears, and the cranks are located on opposite sides of the cable axis, ll

Однако известное устройство сложно по конструкции и ненадежно в работе. However, the known device is complicated in construction and unreliable in operation.

Цель изобретени - повышение простоты и надежности устройства.The purpose of the invention is to increase the simplicity and reliability of the device.

Дл этого устройство снабжено по крайней мере одним дополнительным кривошипом с т говым роликом и ведомой шестерней, рычагом с зубчатым колесом и дружиной дл прижима т говых роликов к кабелю, при этом рычаг шарнирно соединен с |кривошипами, расположенными по одну сторону от оси кабел , а зубчатое колесо находитс в зацеплении с ведомыми шестерн ми-кривошипов .For this, the device is equipped with at least one additional crank with a pulling roller and driven gear, a lever with a toothed wheel and a brigade to press the pulling rollers to the cable, while the lever is pivotally connected to the cranks on one side of the cable axis, and the gear wheel is engaged with the driven gears of the cranks.

Кроме того, дл синхронного поворота кривошипов дополнительные крйво;шипы , расположенные по разные стороны от оси кабел , могут быть св заны между собой посредством зубчатой передачи .In addition, for the simultaneous rotation of the cranks, an additional edge; spikes located on opposite sides of the cable axis can be connected to each other by means of a gear transmission.

На фиг.1 изображен общий вид устройства; на фиг.2 - вид А фиг.1; на фиг.З - вариант выполнени механизма перемещени кабел с зубчатой передачей .1 shows a general view of the device; figure 2 - view And figure 1; Fig. 3 shows an embodiment of the mechanism for moving a cable with a gear.

Устройство дл зат жки кабелей содержит механизм -1 перемещени кабелей , привод 2 и приспособление дл креплени 3. Механизм перемещени кабелей включает кривошипы 4 с ведущими 5 и ведомыми 6 шестерн ми и т говые ролики 7. Последние расположены на одной оси с ведомыми шестерн ми 6, а кривошипы 4 расположены попарно по разные стороны от оси кабел 8.The cable tightening device includes a cable movement mechanism -1, a drive 2 and a fastening device 3. The cable movement mechanism includes cranks 4 with leading 5 and driven 6 gears and pulling rollers 7. The latter are located on the same axis with driven gears 6 , and the cranks 4 are arranged in pairs on opposite sides of the axis of the cable 8.

Дополнительные кривошипы 9 с т говым роликом 10 и ведомой шестерней 11 шарнирно соединены с кривошипами 4 рычагом 12.Additional cranks 9 with a pulley roller 10 and the driven gear 11 are pivotally connected to cranks 4 by a lever 12.

Claims

With the driven gears 6 cranks 4 kinematically, the gear wheel 13 is connected. For clamping the pull rollers to the cable 8, springs 14 are provided. The cranks, located on one side of the cable, can be connected to cranks located on the other side of the cable using gear 15 (see Fig.3). The cable tightening device operates as follows. Between the traction rollers fills the cable with §. The springs 14 act on the cranks 4 and rotate them around the main axis. The levers 12 q of the rollers move towards each other and clamp the cable 8. The gear 20 carries synchronous movement and the cable is evenly clamped with all the rollers. The rotation of the drive 2 with the help of leading 5 and follower gears is transmitted to the traction rollers 7 and 10, which drive the cable 8. The use of the invention makes the device more reliable and economical. Claim 1. Device for cable tightening, comprising a cable movement mechanism, including cranks with driving and gear wheels and traction rollers mounted on a single axis with driven gears, with krivetipe located on opposite sides of the cable axis, characterized in that in order to increase the simplicity and reliability of the device, it is equipped with at least one additional crank with a pulling roller and driven gear, a lever with a gear wheel and a spring for pressing the pulling rollers to the cable, while the lever is hinged angles coupled to cranks, disposed on one side of the axis of the cable, and the gear is meshed with the driven gears cranks.

2. The device according to claim 2, characterized in that, for the purpose of synchronous rotation of the cranks, additional cranks located one at a time. The two sides of the cable axis are interconnected by gears. Sources of information taken into account in the examination: 1. USSR author's certificate number 407793, cl. B 63 i 5 / 00.30.08.71.
