Недсх;татком данного устройства вл етс громоздкость конструкции, необходимость креплени балки к зданию.Ned; tatkom this device is the cumbersome design, the need to mount the beam to the building.

Наиболее близким -прототипом вл етс устройство, содержащее смонтированную на основании секционную башню с оголовком, снабженную узлами дл креплени подкосов, противовесом, узлами креплени вант и грузовой платформой, взаимосв занной через трособлочную систему с приводом 2.The closest prototype is a device comprising a sectional tower with a tip, mounted on the base, provided with nodes for fastening the struts, a counterweight, cable attachment points and a loading platform interconnected through the cable-block system with drive 2.

Недостатком данного устройства в- чаетс сложность конструкции и мала жесткость и устойчтзвость, обуславлива-The disadvantage of this device is the complexity of the design and the low rigidity and stability due to

ющие необходимость креплени устройства к зданию.the need to attach the device to the building.

Целью изобретени вл етс упрощение конструкции и повышение устойчивости башни без креплени ее к зданию.The aim of the invention is to simplify the construction and increase the stability of the tower without attaching it to the building.

Поставленна цель достигаетс тем, что башн снабжена распорной фермой, выполненной с П-образным проемом дл прохода грузовой платформы, при этом узлы креплени вант смонтированы на The goal is achieved by the fact that the tower is equipped with an expansion truss, made with a U-shaped opening for the passage of the loading platform, while the attachment points of the cables are mounted on

10 оголовке башни, вершинах распорной фермы и на основании устройства, а узлы креплени подкосов - в месте расположени центра т жести распорной фермы с башней и противовесом.The top 10 of the tower, the tops of the extension truss and on the basis of the device, and the attachment points of the struts are located at the location of the center of gravity of the expansion truss with the tower and the counterweight.

Claims

The lifting device comprises a base 1 mounted on it and mounted from separate sections 37 a tower 2 with a tip 3, struts 4, industrial weights 5, a loading platform 6 and a drive 7, Tower 2 is equipped with an extension truss 8 with a U-shaped opening 9 dl pass - yes of the cargo platform 10. At the top of the tower, nodes 11 and 12 are attached with the help of fingers and koshes (on the archery ™ are not indicated) guys 13 and 14, fixed on the farm 8 with brackets 15 and 16.. Cap 3, made in the form of a spatial pyramid by squaring a rectangle and with triangles adjacent to its parallel sides. At the vertices of the latter, they are attached to nodes 17 and 18, to which the cables 19 and 2О are fastened. At farm 8, guys 19 and 2O are secured with brackets 21 and 22. On tip 3, there is a housing 23 with two blocks 24, through which the cable 25, which is connected to the drive winch 7 at one end and the platform 10 at the other end. 23 is provided with units 26 to which a guy is attached 27. The guy 27 on the truss 8 is fixed with brackets 28. The guys 13, 14, 19, 20 and 27 are attached to the base 1 using tension devices 29. The truss consists of three separate spatial structures, The design of chi 30 is rigidly attached to the girth of the sections of the tower 2, and structures 31 and 32 are made in ide triangular -DOK peers. The farm 8 is also provided with a knotted 33 for connecting to them the pop-picks 4 with counterweights 5. The installation of the load-lifting device is carried out as follows. On the prepared ground platforms, a base 1 and an anti-scale 5 are installed. On the roof of the building a monolith concession (not shown) is fixed, through which the drive 7 of the cargo winch of the drive 7, which is attached to one section of the tower 2, is stored and the work with water 7, this section is installed on base 1. Further, in the same way, tower 2 is built up approximately to the middle of its height. Then, two sections fastened on the ground are attached to farm 8 so that its middle is located at the junction of the sections. After that, the guys 13, 14, 19, 20 and 27 are attached to the tensioning devices 29, and the other ends of the cables are guided through the brackets, located in five places on the farm 8. Then this collection54. Ku set on a stackable tower. Then they continue to increase sections. tower 2 to a certain height, except the uppermost section. The uppermost section is connected on the ground with the tip 3, attached to them with the help of fingers (not shown) the ends of all five shafts equipped with koushs (not shown), then this BTOpjTO assembly is raised by the mounting console to the tower and fixed. All the cables are tensioned by the devices 29, at the same time checking the tower 2 by a plumb line, and clamping the shackles with brackets on the truss 8. The lifting device works as follows. Platform 10 is loaded with building materials, the drive 7 is turned on and it is raised to the required floor. After the materials are unloaded, platform 10 is lowered and the process is repeated. Thanks to the sectional implementation of the tower 2 and the struts 4, as well as the possibility of re-. The installation of the truss 8 over the tower makes it easier to choose the optimum height for the load of the lifting device when installing it to various types of buildings. Claims A building lifting device comprising a sectional tower with an OGOLT mounted on the base; provided with brace attachment assemblies, a counterweight, cable attachment assemblies, and a loading platform interconnected by means of a cable assembly system with a drive characterized in that, in order to simplify the design and increase the stability of the tower without attaching it to the building, the tower is equipped with an expansion truss, made with a U-shaped opening for the passage of the loading platform, while the attachment points of the cables with mounted on the top of the tower, the tops of the extension truss and on the basis of the device, and the attachment points of the struts are located at the location of the center of gravity of the expansion truss with the tower and counterweight.
