Abstract
Изобретение относитс к грузоподъемным механизмам, а именно к предохранительным устройствам лебедок, предотвращающим полное сматывание каната с барабана лебедки. Цель изобретени - повышение надежности, Ограничитель содержит шток 1, взаимодействующий одним концом через отверстие 3 с канатом 4, другой конец штока 1 выполнен в виде проушины. Сквозь отверстие проушины 5 проходит промежуточный элемент, выполненный в виде гибкой св зи 6, один конец которой закреплен вне барабана 2, а другой взаимодействует с конечным выключателем 9. В проушине 5 вдоль оси штока выполнено отверстие, в котором установлен с возможностью аксиального перемещени подпружиненный посто нный магнит, на стержне штока 1 выполнен шпоночный паз, в котором размещен конец установочного винта, предотвращающий поворот штока вокруг своей оси. Шток выполнен из немагнитного материала. Поле посто нного магнита должно быть больше усили пружины. 2 з.п. ф-лы, 4 ил. соThe invention relates to lifting mechanisms, namely to winch safety devices that prevent the rope from completely winding up from the winch drum. The purpose of the invention is to increase reliability. The limiter comprises a rod 1, which interacts at one end through an opening 3 with a rope 4, the other end of the rod 1 is designed as an eyelet. An intermediate element, made in the form of a flexible link 6, passes through the hole in the lug 5, one end of which is fixed outside the drum 2, and the other interacts with the end switch 9. In the eye 5, a hole is made in the lug 5, which is axially moved This magnet, on the rod of the rod 1, has a keyway, in which the end of the set screw is placed, preventing the rod from turning around its axis. The stem is made of non-magnetic material. The permanent magnet field must be greater than the spring force. 2 hp f-ly, 4 ill. with
