The invention relates to methods of installation and special works in construction and can be used for the installation of lengthy vertical structures, in particular devices operating in the chemical, oil refining, food and other sectors of the national economy.

The purpose of the invention is to reduce the complexity of installation of equipment.

Figure 1 shows the apparatus and the portal in its original position; figure 2 is the same, side view; on fig.Z - the stage of lifting the mounted device

re, rises to a position close to the vertical. Further work of the tackles ensures the lifting of the apparatus to a full reduction in length.

(corresponds to

40-50 angle of inclination of the apparatus to the horizontal).

Qi 1 rests on hinge 2 fixed on foundation 3 and construction 1. At the other end, construction 1 rests on the sleeper display 4. The shortened portal 5 with the lower end (ball-and-tackle polyspas with niro) rests on the sleeper lining 6, and the upper cross-bar 7 through the tackles 8 is connected to the mounting nipples 9 fixed on the structure 1. A hook of a load-lifting crane equipped with a polyspast 10 is fixed to the base of the portal (lower girder) at point 11. When using two

of the cranes, their hooks are slings at points At points 12, the lower girder of the gantry is connected to flexible grip 13, which consists of two tackles, with other ends connected to straps 14 attached to the hinge 2

The next stage of the lift is carried out with the help of a crane, staked out for the foundation of the portal, and continues until the apparatus — the portal of unstable equilibrium — reaches the system. The final installation of the device is made by a brake system.

After alignment and securing the apparatus on the foundation, the removal of the rigging means without braking the apparatus from fast-35 climbing work, rolling over the foundation to the fitting 15 of the apparatus is attached by the end of the brace 16 attached by the other end to the winch (not shown) ..40

Slinging a lifting crane before installation can be carried out by a cable sling 17 at point 11 according to the scheme shown in Figures 1 and 2. When using two cranes 5, the slings can be shortened, the cranes are located on both sides of the mount. By increasing the length of the chain hoists 8 and the portal pulley pulley they lower it to the surface of the ground, where the tackle is disconnected from it. Then remove the upper bolt and the portal with a crane can be reused for its intended purpose.

Claims (1)

Invention Formula The method of lifting a lengthy structure into a vertical position, which consists in the fact that it is lifted by turning the relative apparatus, and they are attached to the portal at points 12. The slinging location of the structure 1 is selected from its center of the body of the tin. When using one lifting crane, the slinging point should be located near the top of the apparatus, which ensures the minimum length of the sling 1 7. The equipment is installed in the following IM way. Before lifting, the slinging unit is positioned and the portal is installed so that the portal pivot hinge and the slinging device point are in the same vertical plane, while the upper gantry of the portal rests on the unit's skirt, which creates some angle (other than zero) between the portal axis and horizontal and significantly reduces the load in the snap at the initial moment of lifting the portal. Under tension tal rotate cargo hoists in a pivot hinge, rises to a position close to the vertical. Further work of the tackles ensures the lifting of the apparatus to a full reduction in length. (corresponds to 40-50 angle of inclination of the apparatus to the horizontal). cargo tackles cargo tackles The next stage of the ascent is carried out with the help of a crane, staked out for the foundation of the portal, and continues until the apparatus — the portal of unstable equilibrium — is reached. The final installation of the apparatus is made by the brake system. After alignment and fixation of the apparatus on the foundation, climbing works are carried out, By increasing the length of the tackle 8 and the tackle of the crane, the portal is lowered onto the surface of the ground, where the tackle is disconnected from it. Then remove the upper bolt and the portal with a crane can be reused for its intended purpose. Invention Formula A method of lifting a lengthy construction to a vertical position, in that it is lifted by turning relative to a support hinge by means of a crane and a stand, the base of which is connected to the crane hook and by means of a flexible link with the hinge axis, characterized in that , in order to reduce the complexity of the installation of a lengthy design, a self-mounting portal, the base of which is attached to the crane hook, is used as a stand, is placed in an intermediate position with the help of cargo polyspasts of a self-aligning portal Lispastov, then a lengthy, the design is rotated into a vertical position by a crane. f. .-five Editor A.Lezhnina Compiled by V.
