Description

The invention relates to hoisting machinery, in particular, to devices for mounting the second 'tier of two-tier horizontal structures.

t

A device for mounting the second tier of two-tier horizontal structures is known, comprising lifting means and a pivoting device including a support frame with a roller for laying the entire mounted structure [1J.

However, the known device does not allow the use of jib cranes for installation in the design position of horizontal cylindrical structures of the second tier due to the limited lifting height of the crane hooks without creating 20 mounting openings for placing elongated crane arrows in them. With a large number of horizontal cylindrical structures (for example, in camp basements of 25 breweries), there is a need to delay the construction of the coating. buildings ',' since the specific weight of the area of the installation opening. to the entire coverage area of the building reaches 90%. thirty

The rollers 11 are rigidly fixed on the shoulder 10 of the lever 2, the rollers 12 are also mounted on the bent shoulder.

The consoles 5 of the frame 1 are connected to the shoulders 10 of the lever 2 by means of removable axes (for example, fingers 13), and the rollers 9, 11 and 12 are located in the same vertical plane at an angle of 120 ° to each other and are pressed against the cylindrical structure 14 of the lower tier, forming her swivel joint.

The device operates as follows. . ·

On the mounted horizontal cylindrical structure of the first tier and the horizontal cylindrical structure 7 of the second tier 7 mounted on the supporting frame 1 with a crane 4, two levers 2 are superimposed, the shoulder 10 ι of each rocker arm is connected to the consoles 5 of the supporting frame by fingers 13. .-. In this case, the rollers 11 and 12 on the lever 2 and the rollers 9, mounted on the stops 8, are located in the same vertical plane at an angle of 120 ° to each other and are pressed against the cylindrical structure. section 1.4 of the lower tier, forming a swivel joint with it.

The crane 4 is slinged in the lower console 3 of the support frame 1 and begin to lift the frame 1c with the cylindrical structure 7 of the second tier located on it together with the levers 2. In this case, the frame 1 rotates around the formed hinge and brings the mounted structure 7 to the design position.

After fixing the mounted structure 7 of the second tier in the design position, use the shelves 15 to remove the fingers 13 and disconnect the levers 2 from the support frame 1. Lowering the support frame 1 to the foundation with a 4 ”·· crane, remove the levers 2.

The use of this device allows to increase the safety of installation work, as well as to automate work in wall conditions without performing installation openings in the building.

785187 two consoles 5 and supports b for the structure to be mounted 7. On the side posts of the frame there are rigid supports 8 with rollers 9 on the ends. Rollers 11 are rigidly locked on arm 1o of lever 2, rollers 11 are also fixed on bent shoulder. Consoles 5 of frame 1 are connected to shoulders 10 of lever 2 by means of removable axles (for example, pins 13), rollers 3, 11 and 12 are located in one vertical plane at an angle of 120 to each other, and 14 lower rus are pressed to the central structure, forming a pivot joint with it. The device works as follows. . . . On the mounted horizontal cylindrical structure of the first tier and laid down on the supporting frame 1 a horizontal chain and on the second tier 7, the lever 2 is superimposed by a crane 4, the arm 10 of each rocker arm is connected to the brackets 5 of the supporting frame with the fingers 13. /. rollers 11 and 12 on lever 2 and rollers 9, fixed on stops 8, are located in the same vertical plane at an angle of 120 to each other and are pressed to the cylindrical design 1.4; not; with the snow ruster, forming a rotary hinge with it. : Crane 4 lines in the lower console 3 of the support frame 1 and begin to lift the frame 1c with the cylindrical structure 7 of the second Russian located on it, together with rycha.gami .2. In this case, the frame 1 is rotated around the formed hinge and leads the mounted structure 7 to the design position. After securing the mounted structure 7 of the second Rus in the design position, using the shelves 15, remove the fingers 13 and detach the levers 2 from the supporting frame 1. Lowering the supporting frame 1 with the crane 4 onto the foundation, remove the levers 2. The use of this device allows to increase the safety of the installation work, as well as to mechanize the work in interior conditions without making installation gaps in the building. Claims of the Invention A device for mounting a second rus of two-dimensional horizontal structures containing lifting means and a pivoting device comprising a support frame with a roller for laying the structure to be mounted on it, aptly so that structures in cramped conditions, it is equipped with three-shoulder arms, the two arms of each of which have rollers, and consoles for detachable connection to the three-shoulder arms are fixed on the supporting frame, while iki on the arms and the support frame are arranged in the same vertical plane at uglom.120 to each other.
