Abstract

Изобретение относитс к устройствам дл механизации ремонта железнодорожного пути. Цель изобретени - повышение эксплуатационной надежности и долговечности . При движении штока 15 влево оба рычага 14 и 18 с т гой 16 и пружиной 17, поворачива сь против часовой стрелки, перемещают рабочую головку 10 вниз. В случае несовпадени граней рабочей головки 10 и гайки рабоча головка 10, соприкоснувшись с гайкой, останавливаетс , продолжа вращатьс с небольшой частотой. Останавливаетс и рычаг 18, а шток 15 продолжает движение влево, поворачива рычаг 14 и т гой 16 сжима пружину 17. Взаимодействие между торцами вращающейс рабочей головки 10 и гайки происходит под усилием, завис щим от параметров пружины 17, которое примерно в 10 раз меньше усили , развиваемого гидроцилиндром. Поскольку рабоча головка 10 продолжает вращение, совпадение граней происходит за короткое врем и сжата пружина 17 досылает рычаг 18 и рабочую головку 10 до нижнего положени . Именно поэтому и снижаетс взаимный износ рабочей головки и гайки, повышаетс их долговечность. По окончании завинчивани или отвинчивани гайки гидроцилиндр 12 перемещает шток 15 влево, рычаг 14, воздейству на рычаг 18 тыльной стороной пружины т ги 16 поворачиваетс по часовой стрелке, поднима рабочую головку 10 в верхнее положение. 3 ил.The invention relates to devices for mechanizing the repair of a railway track. The purpose of the invention is to increase the operational reliability and durability. When the rod 15 moves to the left, both levers 14 and 18 with thrust 16 and spring 17, turning anti-clockwise, move the working head 10 down. In the case of a mismatch between the faces of the working head 10 and the nut, the working head 10, coming into contact with the nut, stops, continuing to rotate with a small frequency. The lever 18 also stops and the rod 15 continues to move to the left, turning the lever 14 and the spring 16 squeezing 17. The interaction between the ends of the rotating working head 10 and the nut occurs under a force depending on the parameters of the spring 17, which is about 10 times less than the force developed by hydraulic cylinder. As the working head 10 continues to rotate, the coincidence of the faces occurs in a short time and the spring 17 is compressed and delivers the lever 18 and the working head 10 to the lower position. That is why the mutual wear of the working head and the nut is reduced, their durability is increased. After screwing or unscrewing the nut, the hydraulic cylinder 12 moves the rod 15 to the left, the lever 14, acting on the lever 18 with the back of the spring of the rod 16 turns clockwise, raising the working head 10 to the upper position. 3 il.

Invention Formula

A device for screwing and unscrewing the nuts, comprising a console mounted on a movable platform with a rotary crosshead and placed on the last working head with a hydraulic motor for its rotation, a hydraulic cylinder controlling the position of the working head, connected to the last elastic connection, turn sensors of the crosshead and lowering the working head

arcuate stop for interaction with the rail and spring-loaded finder, which means that, in order to increase operational reliability and durability, the device is equipped with a bracket rigidly fixed to the cross bar on which the hydraulic cylinder controls the position of the working head, and the elastic connection is formed two two-arm levers mounted on a bracket on a common axis, the first of which is pivotally connected by one arm with the rod of the specified hydraulic cylinder, and mounted on the other shoulder a ha ha

with the spring, the second lever with one shoulder is pivotally connected to the working head, and its other shoulder is mounted on the specified tag and pressed by a spring connected to the shoulder of the first lever, while the arcuate stop is rigidly mounted on the bracket, and the finder is pivotally mounted on the bracket with the ability to turn to the working head.
