Description

Изобретение относитс к строительно-монтажным работам и может быть использовано в тех случа х, когда возникает необходимость повернуть конструкцию .из вертикального положени а горизонтальное.The invention relates to construction and installation work and can be used in cases where it is necessary to rotate the structure from the vertical position and horizontal.

Известен способ пов 3рота длинномерной конструкции, заключающийс в выполнении операции закреплени вспомогательной стрелы в основании длинномерной конструкции, соединени вспомогательной стрелы с длинномерной конструкцией посредством поддерживающего устройств-а, первоначального поворота конструкции, соединени вспомогательной стрелы с т говым устройством и последую1цего поворота конструкции в заданное положение р 1Недостатком известного способа вл етс отсутствие возможности предварительного подгона оснастки, что в определенной степени имеет место.The known method is to rotate a long construction, which consists in performing the operation of securing the auxiliary boom at the base of the long construction, connecting the auxiliary boom with the long construction by means of a supporting device, initial rotation of the structure, connecting the auxiliary boom with the traction device and then rotating the structure to a predetermined position p 1 The disadvantage of this method is the lack of the ability to pre-fit the tooling, which lennoy degree takes place.

когда длинномерна конструкци сначала поднимаетс (поворачиваетс ) из горизонтального положени в вертикальное , а потом с помощью той же оснастки опускаетс из вертикального положени в горизонтальное.when a lengthy structure is first raised (rotated) from a horizontal position to a vertical one, then it is lowered from a vertical position to a horizontal one using the same tooling.

Цель изобретени - обеспечение безопасных условий производства работ .The purpose of the invention is to provide a safe working environment.

Поставленна цель достигаетс The goal is achieved

10 тем, что до закреплени вспомогательной стрелы в основании конструкции последовательно соедин ют вспомогательную стрелу с т говым устройством и длинномерной конструкцией, затем 10 in that, prior to securing the secondary boom at the base of the structure, an auxiliary boom is connected in series with the traction device and a long structure, then

Claims

15 raise the auxiliary boom by means of traction and support devices and carry out an initial rotation of the long-length design, after which the auxiliary boom is fixed at the base of the structure and the subsequent rotation of the structure to the predetermined position is made. FIG. 1 shows a lengthy structure (for example, a mast and an auxiliary boom in the initial position, the tip of the boom is connected to the pulling device); in fig. 2 operations of connecting the auxiliary boom to the supporting device; in fig. 3 — auxiliary boom lifting operation; Fig. "k" shows the operation of turning the mast through a certain angle; in fig. 5 anchoring of the secondary boom at the base of the swinging mast; in fig. 6 shows the position of a long structure after its rotation to a predetermined position: in FIG. 7 — node I in FIG. 4. The method of turning a long structure is considered by the example of dismantling the mast by turning it from a vertical to a horizontal position with the help of an auxiliary boom. The auxiliary boom head 1 is connected to the traction device 2; pre-mounted on the mast 3. Then connect the root of the auxiliary boom 1 with support-. the living device 4, also pre-mounted on the mast 3, lifts the auxiliary boom 1 with the HELP of these devices: t 2 and supporting C, rotate the mast 3 at some initial angle, the T1 of which the root of the auxiliary boom 1 is in close proximity to the pivot mast 3. If necessary, the position of the boom root 1 can be adjusted using a supporting device. Then the root of the boom 1 is fixed at the base of the mast 3, after which the next turn of the mast 3 is carried out to the specified (horizontal) web. Using the proposed method of turning a long structure allows replacing the technically complicated operation of securing the tip of the auxiliary boom on the traction device, which is performed, as a rule, at a considerable height, with a technically simple operation of placing the root of the auxiliary boom in the hinge at the base (or at the base structure and which is performed on the ground or in close proximity to it. Formula of the invention A method of rotating a lengthy structure, consisting in The operation of fixing the auxiliary boom at the base of the lengthy design, connecting the auxiliary boom to the lengthy design by means of a supporting device, initial rotation of the structure, connecting the auxiliary boom to the traction device and subsequent rotation of the structure to a predetermined position, in order to ensure safe production conditions works, before fixing the auxiliary boom in the base of the construction, the auxiliary A boom with a pulling device and a long design, then auxiliary boom is raised by means of a pulling and supporting device and the initial rotation of the long design is carried out, after which the auxiliary boom is fixed at the base of the structure and the subsequent rotation of the structure to the specified position is performed.
