(54) СТРОИТЕЛЬНЫЙ ПОДЬЕМНИК(54) CONSTRUCTION LIFT

Изобретение относитс к подъемным устройствам, предназначенным дл доставки работающих в зону производства сборочно-монтажных работ, и может быть использовано в лини х поточной сборки котлоагрегатов.The invention relates to lifting devices designed to deliver workers to an assembly production area, and can be used in the assembly line of boilers.

Известен строительный подъемник дл доставки работающих в труднодоступные узкие пространства, который имеет установленный на рельсах портал с перемещаемой по вертикальным направл ющим платформой, не .сущей рабочие площадки, установленные на рельсовых проводниках с возможностью перемещени вдоль платформы и выполненные выдвижными в направлении перемещени портала, чтопозвол ет производить монтаж крупногабаритных изделий по их периметру l.A construction elevator for delivering workers to tight narrow spaces is known, which has a portal mounted on rails with a platform moving along a vertical guideway, not working platforms, mounted on rail conductors that can be moved along the platform and made retractable in the direction of movement of the portal, which allows install large-sized products around their perimeter l.

Однако при работе данного подъемника необходимо перемещение подвижного портала, что не позвол ет обеспечить доступ по всему периметру котлов, собираемых на тележе ном конвейере линии поточной сборки котлоагрегатов при ширине котлов меньшей ширины тележечного конвейера.However, during operation of this elevator, it is necessary to move the movable portal, which does not allow access around the entire perimeter of the boilers assembled on the bogie conveyor line of the assembly line of the boilers at the width of the boilers smaller than the width of the bogie conveyor.

Цель изобретени - расширение технологических возможностей подъемника .The purpose of the invention is to expand the technological capabilities of the lift.

Цель достигаетс тем, что по торцам платформы консольно установлены дополнительные поперечные направл ющие с перемецающе йс по ним дополнительной площадкой, причем длина консольной части направл ющих равна полуразности максимальной и минимальной ширины обслуживаемых изделий.The goal is achieved by installing additional transverse guides along the ends of the platform with transferring an additional platform along them, and the length of the cantilever part of the guides is half the maximum and minimum width of the products served.

Подъемник состоит из рамы 1, двух вертикальных колонн 2, платфорг ы 3, на которой размещены площадка 4 с The lift consists of frame 1, two vertical columns 2, platform 3, on which is located the platform 4 with

Claims

20 transversal direction and two bridges 5 longitudinally displaceable in a horizontal plane. Platform 3 is suspended on chains 6, connected with the drive of its vertical movement 7, and provided with longitudinal guides and 8 and transverse 9. Guides 9 are mounted console and fixed on the ends of platform 3, the length of their cantilever part is equal to half difference and maximum the minimum width of the serviced products. In a horizontal position, the platform is held by rollers 10, fixed in the frame of platform 3. Platform 4 is a frame, along the ends of which are rollers 11 placed in transverse guides 9. Platform 4 and tics 5 are equipped with individual electromechanical movement drives. The device works in conjunction with the conveyor 12. The lift works as follows. When the conveyor 12 is moved, the elevator plate is in the upper technological position. After the movement of the conveyor 12 is completed, the platform 3, the platform 4 and the bridges 5 are installed in a position convenient for carrying out the necessary assembly operations. The lift and lowering of the platform 4 and the bridges 5 are made by changing the position of the platform height, kinematically connected by chains 6 - with the drive of its vertical movement 7. The platform 4 and the bridges 5 move on the rollers along the platform guides 8 and 9 with individual drives displacement., use for displacement in the transverse direction of the site. mounted on rails fixed on the platform, the mass of which is several tens of times less than the mass of the mobile portal, allows to reduce the installed capacity of the lift by 30% and reduce electricity consumption; simplify the design of the lift and increase productivity by 10% when assembling boilers on a production line. Claims of the Invention A construction hoist comprising a frame on which vertical columns are installed with a platform moving along their guideway, carrying a working platform, characterized in that it is equipped with a cantilever mounted on the ends of the platform with additional transverse guides with moving on them an additional platform, and the length of the cantilever part of the guides is equal to half the difference between the maximum and minimum width of the products being serviced.
