Description
бовидный стержень 5 нижней частью, имеющей резьбу, ввинчен во втулку 7 нижней секции срединени .The stem rod 5 is threaded in its lower part and threaded into the sleeve 7 of the lower center section.
При разборе секций башенного крана накидна гайка 2 отвинчиваетс и Ьеремешаетс до нижнего положени . Вместе с накидной гайкой защитна втулка также отвинчиваетс и перемешаетс вниз, постепенно закрыва резбу на втулке 1.When disassembling the sections of the tower crane, the union nut 2 is unscrewed and stirred to a lower position. Together with the flare nut, the protective sleeve is also unscrewed and stirred down, gradually closing the thread on the sleeve 1.
При навинчивании накидной гайк;и 2 зашит на втулка 3 также перемешаетс вверх.When screwing in the cap nut, and 2 is sewn onto the sleeve 3, it will also be stirred up.
Использование изобретени позволит избежать повреждений резьбы на нижней части секции крана при транспортировке и монтаж Выбранное соотношение высоты зубьев и шага резьбы (вьюота зубьев равна или больше шага резьбы) обеспечивает надежно зацепление накидной гайки 2 и защитной втулки 3 во врем отвинчивани накидной гайки 2.Using the invention will avoid damage to the thread on the lower part of the crane section during transportation and installation. The selected ratio of tooth height and thread pitch (tooth angle equal to or greater than the thread pitch) ensures reliable engagement of the cap nut 2 and protective sleeve 3 during unscrewing the cap nut 2.
