Abstract

This invention relates to a lifting and transport machinery. The purpose of the invention is the expansion of operational capabilities by ensuring the installation of fragile tons of human products. The gripping device contains a main band 1 and an additional band 3, each of which consists of a pair of supporting beams 4, connected at the top by straps 18, and at the bottom - slings 6. Each sling 6 consists of roller collars connected by a rope, and between clips are supported roller links. Bands 1 and 3 are interconnected by an articulated thrust 5 and through blocks 21 and 22 by means of ropes 23 are connected to a cross-bar 20. When lifting the cross-bar 20, the product 2 rotates from horizontal to vertical position due to movement of the ropes 23 between blocks 21 and 22. At the same time on the product 2 is distributed evenly, which ensures its preservation, 7 Il. SC

FIELD OF THE INVENTION The invention relates to a hoisting-and-transport machine building industry, namely to load handling devices designed for the installation of long structures.

The purpose of the invention is the expansion of operational capabilities by ensuring the installation of fragile tons of human products.

Figure 1 shows the device, the general view of figure 2 is view A of figure 1; in FIGURE 3, the scheme for storing the rope in the chain hoists in FIG. 4 is a strap (sweep); figure 5 - section bb in figure 4; figure 6 is a section bb In figure 4; figure 7 - node I in figure 2.

The gripping device comprises a main band 1 fixed on the fragile product 2 on the side of its dexterity, and an additional band 3 fixed on the side of the base of the product. Each band consists of two bearing beams 4, supported on the product, located on both sides of the product. Bearing beams 4, located on the same side of the product, are interconnected by means of hinge rods 5 and support beams, located on opposite sides of the product, are pairwise interconnected by two slings 6, covering the product from below. Each sling is a flat polyspast 7, roller cages 8 of which are attached to the brackets 9 of the supporting beams 4. In this case, the hoist 7 of each bandage is stored with one rope 10 and provided with support-roller links 11 located between the roller collars 8, and roller links 11 have two bearing surfaces and, accordingly, two rows of rollers 12. To ensure the minimum distance between roller bearing links, the bushes 13 are mounted on the extreme branches of the rope. Roller bearings 11 and bushes 1 3 can be made detachable (divided into two halves along the plane of the rope 10), so that, if necessary, the estimated number lix can be removed one, two at one end of the line 6 and the same number of them mounted (put on the polyspast cables) his friend

The attachment points of the load gripping bodies, made in the form of brackets 14, are on the main band 1 from below, and on the additional band 3 from above, while the brackets 15 are attached to the bracket of band 1, the brackets 4 lean on the product through the support rollers 16 fixed on the ends of the bearing beams. The supporting beams 4 are fixed on the product with the help of a flexible rod 1 7 and column 18.

Product 2 is located on supports

19, the hook is attached to the crane hook

20, on which the blocks 21 are fixed on both sides. To the brackets 14 of the supporting beams of the additional brace

and to brackets 15, blocks 22 are attached, on which two ropes 23 are stored. To turn the product to the vertical position, serve as a bore 24 and an adjustable delay 25.

The device works as follows.

The slings 6 are fastened at one end to the supporting beams 4 located on one side of the product 2. The beams 4 are connected by straps 18, and they have the maximum length. Depending on the required length of the sling and the load on it, the number of links 11, the length and diameter of the cable 10 are selected accordingly. The equipment assembled on the supporting beams and suspended from the crane hook is lowered onto the product. When tensioning the straps 18, the lowering is stopped, they are brought under product 2 and the free ends of the slings 6 are attached to the brackets 9 of the supporting beams 4. Set to pull 17 on the same horizontal line with the center of mass of the product 2 and wrap all the rigging by lifting the crane hook and choose slack tie 18, preventing the product from falling out in a vertical position. If product 2 has a non-linear generatrix, beams 4 are fitted to it by swiveling them with hinged bolts 5 ..

When lifting the crosspiece 20, the product 2 rotates with respect to the core 24 and takes up a vertical position, while the ropes 23 change the length of the branches, moving along blocks 21 and 22. After the product has been removed and secured in a vertical position, the device is removed from the product in reverse order.

If it is necessary to rotate the product around its longitudinal axis, the straps 18 are loosened, the roller support links 11 are dismantled at one end of each sling 6, and the same number of these links are mounted at the other end. Then rotate the product 2 in the direction of the newly mounted links 11.

gripping bandage with a hoisting rope attachment unit, characterized in that, in order to expand operational capabilities by ensuring the installation of fragile bodywork products, it is provided with an additional gripping band with a hoisting rope attachment assembly and when the horizontal rod connects the main bundle is gi 17, strapping 18, blocks 21 of the sales with additional, and each band and 22, the ropes 23 are not installed, they include a pair of supporting beams, replaced by a four-leg sling connected from above t zhkoy, and bottom - the conventional design the two straps, each of which

When lifting a long product, 15 is a flat chain hoist.

With roller collars interconnected by a cable common to both slings, with this binder, the attachment points of the hoisting ropes are located in the middle 20 of the supporting beams and, on the main load, low permissible tensile stresses, give two pairs of balanced supports.

The invention allows the lifting and installation of fragile tons of human.
