RU79543U1 - CRANE FOR LIFTING AND DELIVERY OF LOADS ON THE ROOF, INTERIOR DOORS, LOGGES AND BALCONY OF BUILDINGS (FASTENING ON CLAMPS) - Google Patents

Abstract

The technical solution relates to the construction industry and can be used in the manufacture of jib cranes, mini-hoists for lifting and supplying goods to buildings under construction and under repair. A crane for lifting and supplying goods to roofs, floors, slabs for arranging loggias and balconies of buildings under construction and repaired, comprising a stand, an easy-mounted boom mounted on it, rotated in a horizontal plane by a rotary device using a handle with the boom securing it in the desired position, a winch with a cable and a gripping device, characterized in that the crane stand in the working (vertical) position is set using two length-adjustable struts; the lower end of the strut, installed (in plan), preferably perpendicular to the outer edge of the building plate, is bolted to the plate, and the lower end of the second strut (parallel in plan to the exterior wall of the building) and the lower end of the crane stand are fixed to clamps installed on the edge of the plate.

At the same time, the use of clamps reduces the time required to install the crane by reducing by three times the amount of work required to drill concrete slabs for installing bolts (anchors).

The manufacture of the proposed crane is possible at any machine-building enterprise using conventional materials and equipment.

Description

The utility model relates to the construction industry and can be used in the manufacture of small crane jib cranes designed to lift goods to buildings under construction and under repair after removal of the tower crane from the facility.

Known small-capacity cranes for lifting building materials: - doors, windows, finishing materials, such as jib type "Pioneer" KS-500 and KL-3, cranes cantilever beam type "Out the window, on the roof" KRK-320 and KBK [1 ], [2], as well as hoists of foreign manufacture AIRONE 200-300 [3], Minor Pluma [4]. All of them, for installation in the working position, require the use of a counterweight (counterweight) and do not have a rotary boom device for supplying cargo to the object and returning the boom to the load lifting position.

The closest technical solutions for the totality of coinciding features and the achieved technical result are, selected as prototypes, the technical solution for the utility model patent [5] No. 56365 "Crane for lifting and feeding goods into the window of a building" with priority January 21, 2006) (Prototype 1) and the AIRONE 200-300 elevator in the outdoor installation option (Prototype 2), see the appendix.

The advantage of the prototype 1 is the presence in its design of a rotary mechanism of the boom, however, it is not suitable for installation in open areas, which excludes the possibility of using it to supply cargo when performing work on the manufacture or repair of the roof of the building.

The disadvantage of prototype 2 is that to install it in the working position requires the use of a counterweight (counterweight), in addition, this crane does not have a device for turning the boom, which creates certain inconvenience in its use.

The claimed technical solution is devoid of these disadvantages. The proposed design allows the installation of the crane without using a counterweight in the open area of the attic or floor floors, as well as on the protruding plates intended for the device of loggias and balconies, while turning the boom in the horizontal plane and fixing it in the right position is carried out using a rotary device with little effort working operator.

The technical result achieved is achieved by installing and securing the crane strut in a vertical position with

2 struts adjustable along the length, the upper ends of which are fixed at the top of the crane support column; the lower end of the strut installed (in the plan) perpendicular to the outer edge of the plate is fixed to the plate on a bolt (hairpin), and the lower end of the second strut and the lower end of the crane support strut are fixed to clamps installed on the edge of the plate.

When conducting analysis of the prior art in patent and other technical literature, analogues that are characterized by identical features, the claimed solution was not found. Therefore, it meets the requirements for utility models.

A crane made using the proposed technical solution when installing it on attic floor slabs can be used to supply materials not only for roofing, but also for providing finishing materials to all lower floors, because due to the rotation of the boom, the cargo platform is partially brought into the opening below the windows, on the loggia or balconies and the cargo is easily removed from the platform.

The claimed technical solution can be implemented at domestic engineering enterprises using conventional materials and equipment.

The claimed technical solution is presented in Fig. In the working position on the floor slab.

The crane consists of a support rack 1, hinges 2 for fastening the boom 3 to the rack, rotated in a horizontal plane by the rotary device 4 by means of the handle 5. The crane has a winch 6 with a cable 7, a control panel 8 and a cargo platform 9. At the lower end of the rack 1 there is box-shaped support 10 with a bolt hole for mounting the stand on the clamp 11. To the upper end of the stand in plan, at an angle close to 90 °, two protrusions 12 are fastened with holes for the bolts or studs mounted on them 13. To hold the stand 1 in a vertical m position are two strut 14. The upper ends of struts 15 are lugs with holes for connection with the post, and the lower ends of the same lugs for fixing one of the struts on the clamp 16 and the other on the bolt 17 mounted on the slab. To install the rack 1 of the crane in a vertical position in the struts there is a device - screw-nut 18, which allows you to adjust the length of the struts.

The crane is used as follows:

A hole for a bolt 17 is drilled on the plate according to the marking that provides the necessary location of the crane, and two clamps are installed on the edge of the plate. The rack 1 is installed on one of the clamps and fixed in a position close to vertical (without fully tightening the nut on the stud clamp 11. The struts 14 are attached at one end to the protrusions 12 on the top of the rack 1, the other end of one strut is fixed to the bolt 17 on the plate, and the second to the clamp 16 with a light tightening of the nuts on the bolts (studs) .Rack 1 is installed in a vertical position using screw devices 18 in the struts.

After the rack 1 is installed in a vertical position, the nuts of the rack mounting and struts on the bolts (studs) are tightened, an arrow 3 with a winch 6 is mounted on the hinges 2, electricity is connected, a cargo area or a load hook are connected to the rope; in this position the crane is ready for operation.

By acting on the handle 5 of the rotary device, the worker sets the boom in the position for lifting the load (at right angles to the outer wall of the building) and lowers the load platform to the ground. After lifting the load to the required height, the worker, acting on the lever 5 of the rotary device, turns the boom 3 into the building and lowers the load to the site. When lifting goods to the lower floors of the building, the boom turns until the cargo cable touches the wall of the building, after which the cargo platform lowers to touch the building structure element (floor, loggia, balcony, window opening) and unloads.
