Description

Изобретение относитс к подъемно-транспортному машиностроению.This invention relates to a lifting and transport machinery.

Цель изобретени - обеспечение монтажных работ в труднодоступных местах.The purpose of the invention is to provide installation work in hard to reach places.

На фиг. 1 изображено устройство, общий вид; на фиг. 2 - вариант выполнени устройства с дополнительными тросами; на фиг. 3 - вариант выполнени устройства с несущей конструкцией в виде рамы; на фиг. 4 - вид А на фиг. 1; на фиг. 5 - вариант выполнени устройства с рамой, выполненной в виде шарнирного параллелограмма .FIG. 1 shows the device, a general view; in fig. 2 shows an embodiment of the device with additional cables; in fig. 3 shows an embodiment of a device with a frame bearing structure; in fig. 4 is a view A of FIG. one; in fig. 5 shows an embodiment of the device with a frame made in the form of a hinged parallelogram.

Устройство содержит несущую конструкцию 1, узел 2 дл соединени с грузом 3 и узел 4 дл навешивани на крюк 5 грузоподъемной машины. На несущей конструкции установлены попарно блоки 6, огибаемые тросами 7, закрепленные своими концами на перекрытии 8 и на основании 9. Тросы снабжены винтовыми ст жками 10. Несуща конструкци может быть выполнена в виде пары стержней 11 или в виде рамы , 12 (фиг. 3 и 5). Вариант устройства, изображенный на фиг. 2, содержит два дополнительных троса 13, соединенных с т говыми механизмами 14.The device comprises a carrier structure 1, a unit 2 for connection with a load 3, and a unit 4 for being hung on a hook 5 of a lifting machine. On the supporting structure, blocks 6 are installed in pairs, which are enveloped by cables 7, fixed with their ends on the floor 8 and on the base 9. The cables are provided with screw hubs 10. The supporting structure can be made as a pair of rods 11 or as a frame, 12 (Fig. 3 and 5). The device variant shown in FIG. 2, contains two additional cables 13 connected to the traction mechanisms 14.

При создании т гового усили с помощью грузоподъемной машины 15 (а также в сочетании с работой т говых механизмов 14) обеспечиваетс подъем груза (в том числе и его горизонтальное перемещение ) в труднодоступных местах, например под перекрыти ми. С помощью устройства, изображенного на фиг. 5, имеетс возможность подать груз выше точки креплени тросов 7 на перекрытии 8.When generating traction by means of a lifting machine 15 (and also in combination with the operation of the traction mechanisms 14), the load is lifted (including its horizontal movement) in hard-to-reach places, for example, under overlaps. Using the device shown in FIG. 5, it is possible to feed a load above the attachment point of the cables 7 on the ceiling 8.

Claims

1. A device for lifting cargo under an overlap, containing a supporting structure, a unit connected to it for connection with the load and a unit for hanging onto a hook of a load-lifting maschine mounted on the base, blocks placed in pairs on the supporting structure, and cables, each of which is fixed one end on the base and rounds the corresponding

The block of the first pair, characterized in that, in order to ensure installation work in hard-to-reach places, the supporting structure includes two parallel horizontal rods, the blocks are located at the ends of the rods coaxially with the latter, and each cable bends around the blocks of the second pair from below with the possibility fixing its other end on the overlap.

2. The device according to claim 1, characterized in that it is provided with a screw tie for each cable.

3. The device according to paragraphs. 1 and 2, characterized by the fact that it is equipped with two additional cables for connecting each one

with its end with the corresponding pair of blocks, and the other with the traction mechanism.

4. Device on PP. 1 and 2, characterized in that the supporting structure is made in the form of a frame with an assembly at one end for connection with a load, at the other for an attachment to a hook of a lifting machine and a first pair of blocks, and in the middle - a second pair of blocks In this way, the blocks are installed perpendicular to the frame plane.

5. Device on PP. 1, 2 and 4, characterized in that the frame is made in the form of a wedge parallelogram, and the unit for connection with the load is placed in its upper part.
