Description

Изобретение относитс  к области строительства , а именно к приспособлени м дл  монтажа стальных и сборных железобетонных конструкций.The invention relates to the field of construction, namely to devices for the installation of steel and precast concrete structures.

Известна монтажна  лестннца, включающа  опору с рабочей площадкой и фиксаторами дл  креплени  ее к колонне.A known mounting ladder includes a support with a working platform and clamps for fastening it to the column.

Недостатком известной лестницы  вл етс  нен1адежность закреплени  рабочей площадки под действием сжатых пружин с точки зрени  безопасности и удобства в эксплуатации.A disadvantage of the known ladder is the unreliability of securing the working platform under the action of compressed springs from the point of view of safety and ease of operation.

Целью изобретени   вл етс  возмол ность автоматической фиксации лестницы.The aim of the invention is the possibility of automatically fixing the stairs.

Это достигаетс  тем, что рабоча  площадка установлена с возможностью вертикального перемещени  вдоль лестницы при помощи рычажной системы.This is achieved by the fact that the working platform is installed with the possibility of vertical movement along the ladder using a lever system.

На фиг. 1 изображена предложенна  лестница , вид сбоку; на фиг. 2 - то же, вид спереди; на фиг. 3 - узел I на фиг. 1; на фиг. 4- разрез по А-А на фиг. 3.FIG. 1 shows the proposed ladder, side view; in fig. 2 - the same, front view; in fig. 3 shows the node I in FIG. one; in fig. 4 is a section along the line A-A in FIG. 3

Монтажна  лестница включает олору, состо щую из секций / н телескопической части лестницы 2 дл  более точной установки площадки 3 по высоте, четыре Г-образных поворотных фиксатора 4 с т гами 5 дл  привода фиксаторов, подъемные петли 6 площадки 5 и колонну 7 стро щегос  здани .The mounting ladder includes an olora consisting of sections / n of the telescopic part of the ladder 2 for more precise installation of the platform 3 in height, four L-shaped rotary clamps 4 with 5 rods for driving the clamps, lifting loops 6 of the platform 5 and a column 7 of the building .

Работа монтажной лестницы заключаетс  в следующем.The job of the mounting ladder is as follows.

Площадка 3 скользить по направл ющим вверх и ВНиз относительно лестницы 2, т. е. площадка 3 может занимать на лестнице 2 верхнее положение, когда она подн та за петли 6 краном. В этом случае оба поворотных фиксатора 4 повернуты через т ги и рычаги в вертикальное положение.Platform 3 slide along the guides upwards and downwards relative to the stairway 2, i.e., platform 3 can occupy the upper position on the staircase 2 when it is lifted by the loop 6 with a crane. In this case, both swivel clamps 4 are rotated through the rods and levers to a vertical position.

При подъеме краном всей конструкции за летли 6 лестницу вплотную придвигают к колОНне , и площадка свободно охватывает колониу с трех сторон. При опускании краном площадки с лестницей последн   опираетс When the crane lifts the whole structure, after 6 years of flight, the ladder is pulled up closely to the column, and the ground freely encompasses the colony from three sides. When lowering the platform with ladder by crane, the latter rests

на землю, а площадка 3 скользит по направл ющим вдоль лестницы под действием собственного веса, через рычаги и т ги 5 поворачивает фиксаторы 4, замыка  колонну с четвертой стороны.on the ground, and the platform 3 slides along the rails along the ladder under the action of its own weight, through the levers and tie 5 rotates the fasteners 4, the closure of the column on the fourth side.
