Abstract

Изобретение относитс к лесохоз йственному машиностроению и может быть использовано в конструкции лебедок, предназначенных дл подтаскивани из пасек к технологическим коридорам деревьев. Цель изобретени - повышение производительности и улучшение условий труда. Лебедка содержит канатный барабан 4, шарнирно установленный на корпусе 2, и подпружиненный относительно него двуплечий рычаг 9, свободным плечом св занный с двигателем и имеющий ролик 10, длина которого больше длины барабана. Ролик расположен от оси барабана на рассто нии не более радиуса реборды барабана и имеет профильную канавку с направленной от торцов к середине навивкой. При резком изменении нат жени каната и вспушивании последнего на барабане канат воздействует на ролик 10, поворачивает рычаг 9 и отключает двигатель. 1 з.п.ф-лы, 3 ил.The invention relates to forestry machine building and can be used in the construction of winches intended to be taken from apiaries to the technological corridors of trees. The purpose of the invention is to increase productivity and improve working conditions. The winch contains a cable drum 4, pivotally mounted on the housing 2, and a two-arm lever 9 spring-loaded relative to it, connected to the engine with a free shoulder and having a roller 10, the length of which is longer than the length of the drum. The roller is located from the axis of the drum at a distance not exceeding the radius of the flange of the drum and has a profile groove with a coiling directed from the ends to the middle. If the tension of the rope changes abruptly and the latter is rolled up on the drum, the rope acts on roller 10, turns lever 9 and turns off the engine. 1 hp ff, 3 ill.

Claims

Claim

1. A skidder winch comprising a drum with end flanges and a rope-layer connected to a drive through a transmission, a group of guide rollers and a two-arm lever with a roller pivotally mounted relative to it, kinematically connected to the drive, characterized in that, in order to improve working conditions and increase productivity, in the lowermost position, the lever roller is located from the axis of rotation of the drum at a distance of not more than the radius of the flange and is made longer than the length of the drum, at ohm on its cylindrical surface formed with a profile groove directed from the ends to the middle of wound.

2. Winch according to π. 1, characterized in that the winding pitch is equal to the diameter of the rope, and the winding is made multidirectional from the ends.
