Description

The invention relates to load gripping devices used with crane mechanisms for lifting and moving goods, including with a displaced center of mass, mainly large-capacity equipment with a mass of up to 200 tons, including steel vessels, columns, large-sized equipment for nuclear power plants.

Known lifting beam containing a longitudinal beam with an eye for hanging on the hook of the lifting mechanism and holes for fixing the transverse beams on it with a fastening means in the form of a clamp rigidly fixed in the Central part of each of the transverse beams (Patent RU 29713 U1, IPC В66С 1/14, priority of December 2, 2002, publ. May 27, 2003).

The closest technical solution, selected as a prototype, is the universal HUNVB traverse, containing the main longitudinal beam in the form of the main module, equipped with small transverse beams in the form of additional modules, holes for lifting brackets for hanging the main module on the hook of the lifting mechanism using slings and joints its with additional modules. The holes for rigging brackets on the modules are made in the central part and at the ends of the beams on the plates welded to them (Harrington Catalog: Below-The-Hook & Material Handling Equipments, http://www.harringtonhoists.com/products/pdf/ catalog / BTH% 20REV% 201.pdf, p. 17).

The drawback of these traverses is that their design does not allow moving large loads (over 7 tons) and loads requiring more than four suspension points, which limits their functionality. The holes for rigging brackets on the prototype are made on plates welded to the beam, which reduces their strength, reliability and necessitates complex control of critical welded products.

The technical problem of the invention is to increase the lifting capacity of the crosshead for moving loads of large mass (up to 200 tons) and loads requiring more than four suspension points.

The technical problem is solved in that in the modular traverse, containing the main and additional modules of the supporting beams connected by lifting brackets, holes for the lifting brackets for hanging the main module on the hook of the load-gripping body and connecting it to the additional modules, according to the invention, the carrier beams of each module made of a single sheet, holes are made along the entire length of each sheet in two rows along its upper and lower parts, between rows of holes on both sides along each sheet of Varena duct rigidity to provide a lateral longitudinal stiffening modules.

In addition, each module is equipped with supports for installing them on a horizontal surface.

Moreover, each module allows you to use it separately as an independent traverse.

The implementation of the beams of each module from a single sheet and the presence of stiffeners welded on both sides provides lateral longitudinal stiffness of the beams, allows you to move bulky loads of large mass up to 200 tons.

Making holes on the sheet of each module along the entire length of the sheet, two rows of holes along the upper and lower parts of it allow you to move loads of large mass, which require more than four suspension points, and loads with a displaced center of gravity.

Supplying each module with supports provides the ability to install the module on a horizontal surface when the modules and crosshead are not used or for their maintenance.

Using each module separately allows you to use it as an independent traverse for lifting and moving cargo using slings attached to the modules.

The invention is illustrated by drawings, where:

in FIG. 1 presents a traverse modular, main view;

in FIG. 2 is a view A in FIG. 1 shows a main module with additional modules suspended therefrom by means of rigging brackets, side view;

When describing the traverse, the following elements are used:

1 - main module;

2 - additional modules;

3 - load-bearing beams made of a single sheet;

4 - holes on the supporting beams of each module;

5 - cargo;

6 - box stiffness;

7 - rigging brackets in the upper row of holes of the main module for hanging to the load-gripping organ of the crane;

8 - slings for hanging the traverse to the load-gripping organ of the crane;

9 - rigging brackets in the bottom row of the main module for hanging additional modules or slings for lifting loads;

10 - rigging brackets in the upper row of additional modules for hanging them to the main module;

11 - slings for hanging the load on the modules;

12 - lifting brackets in the bottom row of additional modules for hanging slings for lifting loads;

13 - supports on the modules.

The module traverse contains the main module 1 and additional modules 2 suspended from it (Figs. 1–8). The design of the main module 1 and additional modules 2 is the same, they differ only in size. Each module 1 and 2 consists of a supporting beam 3 made of a single sheet. On each sheet along its entire length, two rows of holes 4 are made along its upper and lower parts. The holes 4 serve to rearrange the connection elements in them and establish them at a distance depending on the position of the center of mass of the load being lifted 5. On both sides along each sheet of modules 1 and 2 are welded along its entire length of the stiffening box 6. The stiffening box 6 provides lateral longitudinal rigidity modules 1 and 2. As the elements for connecting modules 1 and 2 to each other for hanging the beam to the load-gripping body of the crane (not shown) and load 5, rigging brackets are used. Rigging brackets 7 installed in the upper row of holes 4 of the main module 1 are used to suspend the traverse to the load-lifting body of the crane using slings 8. In the lower row of holes 4 of the main module 1, lifting brackets 9 are installed; they are used to hang additional modules 2 on them rigging brackets 10 installed in the upper row of holes 4, as well as for hanging the load 5 by means of slings 11 (Fig. 7-9). Rigging brackets 12 installed in the lower row of holes 4 of additional modules 2 serve to lift and transport cargo 5 using slings 11 (Fig. 10). At the ends of each module 1 and 2, supports 13 are welded for mounting them on a horizontal surface when the modules 1 and 2 of the beam are not used, or for their maintenance. Modular traverse allows lifting and moving loads 5 with a displaced center of mass using simultaneously the main 1 and additional 2 modules (Fig. 5-8), and also allows each module to be used separately as an independent traverse using slings 11 (Fig. 9 -10).

Work with the application of the declared traverse modular produce as follows.

To carry out rigging work, taking into account the weight and the center of mass of the load 5, the required number of additional modules 2 is suspended from the main module 1 by means of the lifting brackets 9 and 10. Then the crosshead is suspended by the lifting brackets 7 installed in the upper row of holes 4 of the main module 1, to the load-lifting to the crane body using slings 8.

To lift the load 5, for example, a vessel of the same diameter or the reactor vessel, two additional modules 2 are hung on the main module 1 using the lifting brackets 9 and 10 (Fig. 5), then the slings 11 are brought under the load 5 and hung on the lifting brackets 12. Lifting brackets 7 is installed in the upper row of holes 4 in the center of the main module 1, suspended with the help of slings 8 to the load-gripping organ of the crane and lifting and moving the load 5 is carried out.

To lift and move the load 5 with a shifted center of gravity (Fig. 6), the third additional module 2 is hung on the main module 1 between the additional modules 2 using the lifting brackets 9 and 10, then the slings 11 are brought under the load 5. Similarly, the lifting brackets 7 are installed in the upper row of holes 4 of the main module 1 and suspended from the load-gripping organ of the crane. In this case, the lifting brackets 7 are installed at a distance from each other so as to balance the load 5, providing it with a horizontal position when rigging.

To transport the cargo 5, depending on its diameter and length, you can hang two additional modules 2 and slings 11 directly on the main module 1 (Fig. 7) or one additional module 2 and several slings 11 directly on the main module 1 (Fig. 8) for cargo with variable diameter. For long loads of small diameter, separately use the main 1 or additional module 2 as an independent traverse, hanging slings 11 in the amount of two, three or more (Fig. 9-10).

The use of the proposed modular crosshead allowed moving loads of large mass (up to 200 tons), including those with a shifted center of gravity, for which more than four lifting points may be required. At the same time, the design of the traverse modular allows each of its modules to be used separately as an independent traverse.
