Description

Изобретение относитс кгрузоподъемным механизмам, а именно к переносным лебедкам.This invention relates to load lifting mechanisms, namely, portable winches.

Известна переносна лебед| а, содержаща барабан дл ленточного т гового органа и охватывающую барабан обойму, выполненную с отверстием дл прохождени т гового органа и снабженную крепежным элементом, расположенным Противоположно упом нутому отверстию.Known figurative swan | a, comprising a drum for a belt-type organ and a sleeve around the drum, provided with a hole for the passage of the body and provided with a fastening element located Opposite the said hole.

Недостатком этой лебедки вл етс сравнительно низка надежность ее работы.The disadvantage of this winch is the relatively low reliability of its operation.

Цель изобретени - повышение надежности работы лебедки путем улучшени ее уравновешенности.The purpose of the invention is to increase the reliability of the winch by improving its balance.

Поставленна цель достигаетс тем, что осева плоскость крепежного элемента расположена между рабочей поверхностью барабана и внутренней поверхностью обоймы на рассто нии от , упом нутых поверхностей, большем двойной толщины т гового органа.The goal is achieved by the fact that the axial plane of the fastening element is located between the working surface of the drum and the inner surface of the holder at a distance from the said surfaces greater than twice the thickness of the traction member.

На фиг. 1 изображена лебедка, общий вид; на фиг. 2 - то же, поперечный разрез.FIG. 1 shows a winch, a general view; in fig. 2 - the same cross section.

Лебедка имеет привод 1, редуктор 2, барабан 3 с укрепленным на нем т говым органом i в виде ленты, обойму 5 с кронштейном 6, имеющим проушину 7. Т говый орган расположен в кольцевой канавке барабана, вл ющейс ее рабочей поверхностью и образованной поверхностью дна А боковыми поверхност ми В и С. Над т говым органом расположена внутренн поверхность D обоймы.5. Осева плоскость Е кронштейна параллельна продольной The winch has a drive 1, a gearbox 2, a drum 3 with a belt-shaped i-shaped body i fixed on it, a holder 5 with a bracket 6 having an eye 7. The thrust body is located in the annular groove of the drum, which is its working surface and the bottom surface formed And the lateral surfaces B and C. The internal surface D of the cage is located above the body. The axial plane E of the bracket is parallel to the longitudinal

15 оси барабана и проходит между поверхностью дна канавки и внутренней поверхностью О обоймы на рассто нии более двойной толщины т гового органа .15, the axis of the drum and passes between the bottom surface of the groove and the inner surface O of the holder at a distance of more than twice the thickness of the traction member.

Claims

The longitudinal plane of symmetry F of the eyelet 7 coincides with the plane of symmetry G of the groove perpendicular to the axis of the drum. 39 During the rotation of the drive t of the drum 3 through the gearbox 2, the tang body 4 is wound on the drum, carried out gu. At the same time, the winch maintains an equilibrium in the transverse plane, its initial position does not change: the plane of the tensioned traction body outside the winch remains almost parallel to the axial plane E of the bracket 6, and at the same time the plane of symmetry F of the eyelet 7 remains unchanged. coincides with perpendicular to the axis of the drum by the plane of symmetry G of the groove and, accordingly, of the traction organ. i. The economic effect is 12000 r per year due to the reduction of time for precise installation of the winch along the line connecting the exit point of the pull cable from the pipe and the point of attachment of the winch to surrounding objects. 1 Claims of the Invention A portable winch containing a drum for a traction body and a yoke encompassing the drum, provided with an opening for the passage of the traction body and provided with a fastening element opposite to said opening, characterized in that . By improving the balance of the Winch, the axial plane of the fastener is located between the working surface of the drum and the inner surface of the holder at a distance from the mentioned; : surfaces greater than twice the thickness of a traction organ.
