Abstract

Изобретение относитс к средствам малой механизации и служит дл подъема и опускани грузов, оборудовани , механизмов и машин. Цель изобретени - повышение удобства эксплуатации. В подъемном устройстве, содержащем жесткую вертикальную стойку 1, перемещающуюс относительно ее грузовую опору и грузовой упорный винт 6, вертикальна стойка выполнена гладкой, а грузова подвижна опора состоит из двух элементов 2 и 3, свободно насаженных на стойку, соедин емых с ней посредством съемных горизонтальных стержней 4, располагаемых в радиальных отверсти х 5 стойки, расположенных вдоль стойки на одинаковых рассто ни х друг от друга, а между собой элементы грузовой опоры св заны посредством винта 6, размещенного параллельно стойке 1 в гайке, верхнего элемента 2 и взаимодействующего нижним концом с упором 8 нижнего элемента 3. причем верхний элемент грузовой опоры снабжен кронштейном 9 под груз, а гайка 7 цапфами 10. 2 ил.The invention relates to means of small-scale mechanization and serves for lifting and lowering loads, equipment, mechanisms, and machines. The purpose of the invention is to increase the convenience of operation. In a lifting device containing a rigid vertical rack 1, moving relative to its cargo support and cargo thrust screw 6, the vertical rack is made smooth, and the cargo movable support consists of two elements 2 and 3, freely mounted on the rack, connected to it by means of removable horizontal rods 4 located in the radial holes 5 of the rack located along the rack at equal distances from each other, and between the elements of the cargo support are connected by means of a screw 6, placed parallel no rack 1 in the nut, the upper member 2 and lower end interacts with the focus 8 of the lower element 3. The upper element being provided with a cargo support bracket 9 under the load, and the nut 7 trunnions 10. 2 yl.

Claims

Claim

A lifting device comprising a vertical strut, a cargo support, consisting of 20 arranged one above the other and covering said strut with the possibility of vertical movement of elements, means for fixing the latter at predetermined levels, made in the form of horizontal rods for placing 25 of them in the openings of the above-mentioned elements and strut , and a device for the vertical movement of the upper element of the cargo support relative to the bottom, characterized in that, in order to increase 30 ease of use, the device for vertical movement of the upper element of the cargo support relative to the lower element contains a screw with stops at both ends and a nut connected to it, 35 fastened by a horizontal axis to the bracket of the upper element, and the lower element of the cargo support is made with a contact surface for contacting each of the stops 40 screw.
