(54) СТРОИТЕЛЬНЫЙ ПОДЪЕМНИК(54) CONSTRUCTION LIFT

1one

Изобретение относитс к подъемно-транспортному машиностроению, в частности к строительным подъемникам.The invention relates to a lifting and transport machinery, in particular to construction hoists.

Известен строительный подъемник, содержащий многосекционную мачту с грузоподъемным механизмом и вертикально перемещающуюс по мачте каретку с выдвижной грузовой платформой 1.A construction hoist is known, comprising a multi-section mast with a lifting mechanism and a carriage vertically moving along a mast with a sliding load platform 1.

Однако така конструкци подъемника не обеспечивает точности подачи груза к месту монтажа.However, such an elevator design does not ensure the accuracy of the load to the installation site.

Цель изобретени - обеспечение точности подачи груза к месту монтажа.The purpose of the invention is to ensure the accuracy of the cargo to the installation site.

Цель достигаетс тем, что строительный подъемник снабжен рамой, смонтированной на верхней секции мачты и оснащенной криволинейной горизонтальной направл ющей грузоподъемного механизма.The goal is achieved by the fact that the construction hoist is equipped with a frame mounted on the upper section of the mast and equipped with a curvilinear horizontal guide of the lifting mechanism.

Кроме того, с целью повыщени безопасности проведени работ, рама снабжена ограждением, свободный конец которого оснащен обводным канатом, при этом мачта оборудована нат жной лебедкой и блоками, в которые запасован обводной канат.In addition, in order to improve the safety of work, the frame is equipped with a fence, the free end of which is equipped with a bypass rope, while the mast is equipped with a tensioning winch and blocks into which the bypass rope is stored.

А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 2; на фиг. 4 - узел рабочей площадки; на фиг. 5 - то же, вид сверху.A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 - working site; in fig. 5 - the same, top view.

Подъемник содержит многосекционную мачту 1, наращиваемую снизу стойку с основанием 2, подъемный механизм 3 с грузовыми канатами 4, вертикально перемещающуюс каретку 5 с грузовой платформой 6 и опоры 7 креплени мачты к возводимому объекту.The elevator includes a multi-sectional mast 1, a stackable bottom with a base 2, a lifting mechanism 3 with cargo ropes 4, a vertically moving carriage 5 with a loading platform 6, and a support 7 for fastening the mast to the object being erected.

На верхней секции 8 мачты 1 установto лена ферма 9 с противовесом 10, к которой прикреплена криволинейна горизонтальна направл юща балка 11, дл перемещени по ней грузоподъемного механизма 12.On the upper section 8 of the mast 1, a truss 9 is installed with a counterweight 10, to which a curvilinear horizontal guide beam 11 is attached, for moving the lifting mechanism 12 along it.

Claims

The truss 15 also reinforces the frame 15 of the circular form 13 on the farm 9, on which on the rods 14 the working platform 15 with wooden flooring is hinged on the rods 14 and equipped with supporting folding cams 16 mounted on the brackets 17 with the possibility of moving to the center of the platform (pipe) as reducing pipe diameter. The frame 13 is provided with an annular beam 18, on which is hung a fence 19, made in the form of a grid, the free end of which covers the bypass rope 20 connected through a cable-block system to the winch drum 21. The elevator works as follows. The lifting of the materials for the construction of the pipe is carried out in the container 22 with the pallet on the loading platform 6, moving together with the carriage 5 along the elevator mast using the mechanism 3 with the ropes 4. Raise the platform to the desired height and stop. The load-lifting mechanism 12 is guided along the guide beam 11 to the container 22, grasps it, moves it along the guide beam to the workplaces, and lowers it to the working platform 15. The pallet with the material remains on the working site, and the container returns to the loading platform in reverse order. The mast buildup is performed bottom by section with the help of a lifting mechanism 3 and a mounting cable 23 fixed in a known manner on a rack with a base 2. Each time the mast is lifted, the pipe walls are laid out to a height equal to the height of the mast section. When the mast is lifted, both the working platform 15 and the fence 19 rise with it. Folding cams. 16, the pads 15 are turned downward, and after passing the laying of the pipe, under the action of the counterweight, they are again turned to a horizontal position and, when the mast is lowered, rest on the laying of the pipe. As the internal diameter of the pipe decreases as construction progresses, the bracket 17 of the hinged cam 16 moves to the site center as needed. The bypass cable 20 weakens when lifting the mast and, since the surface of the pipe has a tapered shape, does not hinder lifting, and after lifting by means of a winch 21, the bypass cable 20 pulls up and presses the lower part of the fence 19 (grid) to the outer surface of the pipe. After lifting the mast, a support 7 is installed on it, which is fixed to the embedded parts on the pipe wall. The proposed device provides accurate delivery of cargo to the site, installation and increased safety of work. Claim 1. A construction hoist comprising a multi-sectional mast with a lifting mechanism and a carriage vertically moving along the mast with a retractable load platform, characterized in that, in order to ensure the accuracy of the load to the installation site, the elevator is equipped with a frame mounted on the top section of the mast and equipped curvilinear horizontal load-lifting mechanism.

2. An elevator according to claim 1, characterized in that, in order to increase the safety of the work, the frame is provided with a barrier, the free end of which is equipped with a bypass cable, while the mast is equipped with a tensioning winch and blocks into which the bypass rope is stored.
