The invention relates to the field of elevator transport equipment.

Known devices to “wounds to install cargo in hard-to-reach places, including a load-carrying lever with a gripping body mounted on a cargo suspension, hung with a supporting rope on the hook of the lifting mechanism.

The proposed device is characterized in that the load suspension is made in the form of an L-shaped bracket pivotally connected to the load-carrying lever and connected to it by a polyspast formed by a supporting rope. Moreover, the bracket is made with two points of the olora, and the carrying arm is equipped with stops that interact with the bracket m.

These differences increase the productivity of the device and improve the working conditions when installing goods in hard-to-reach Places by automating the processes of seizure and release of cargo, as well as expand the technology of using the device.

FIG. 1 shows the proposed attachment when transporting cargo; in fig. 2 - the same, and carrying out loading and unloading works.

The hinged device consists of a "Ronstein 1 L-shaped, through the block 2 -which

skipping support rope 3, hanging a speck hook. One side of the L-shaped bracket ends with two spherical onors 4. On the other hand, bracket 1 is connected by a hinge 5 with a load-carrying lever 6 equipped with a gripping body 7, the shape of which depends on the shape of the product. In addition, the carrying arm is connected with bracket 1 by blocks 8 and 9 of the chain hoist. The flexible body of the chain hoist is the supporting rope 3.

On the carrying lever are lanes 10 and 11.

The hinged device works as follows.

When transporting the product 12 (for example, (Shaft), the center of gravity of the grip with the product is located on the axis of the supporting rope. At that, the gripping member 7 is in the extreme upper position, and the stop 10 abuts against the bracket 1 (see Fig. I).

In order to perform loading and unloading operations in a hard-to-reach place, nalimer in a zone closed from above, it is necessary to have a shelf over it or (see Fig. I) a niche 13 with a bottom 14. Spherical openings 4 of the device are turned into il3 niche. The presence of two spherical supports is necessary to make the bracket stable in operation. A crane is turned on to lower the supporting rope 3 with the bracket 1, and the latter sits with spherical supports 4 on the bottom 14 of the niche. Further, the installation of the support rope 3 automatically ensures the rotation of the bracket on the spherical supports and, therefore, the introduction of the product 12 into the area closed from above. Upon further lowering of the supporting rope, the load-carrying lever b is rotated relative to arm 1 (Fig. 2) up to the stop 11, so that the gripping body 7 is lowered, and the product 12 is installed on the prisms 15. After releasing the gripping body 7 from the product 12 n is included on the rise. Automatically, the pick-up body 7 of its upper position rises to its upper position, the load-carrying lever 6 rotates clockwise (Fig. 2) until the stop 10 contacts the bracket 1, and then the device itself rotates on the spherical supports 4, while the center of gravity it does not coincide with the axis of the supporting cable 3. In this position, its spherical supports 4 move away from the bottom .14 of the niche 13. Before lifting, the device is manually deflected slightly so that the lifting gripping member 7 crushes near the article 12 lying on the G5 prism. Similar operations are carried out with an empty gripper, if necessary, to remove the product 12 s. Prism 15. In this case, on the contrary, the arm is manually retracted to some extent in order to lift the gripping body 7 to pick up the product 12. The hinged device rotates. on the spherical supports 4 when lowering the supporting rope 3 until the force on the supporting rope 3 decreases to the value of the tension of the branch of the polyspast rope based on the weight of the product 12 and the load bearing arm 6. At the same time, the center of gravity of the device and Delhi disposed between the unit 2 and the spherical supports 4, closer to the latter. Moreover, the angle of rotation of the bracket when the gripping body 7 is lowered (the load-carrying lever 6 rotates counterclockwise in accordance with Fig. 2) will be greater than when it is lifted (the load-carrying lever 6 rotates clockwise in accordance with Figure 2) due to the equal direction frictional forces between the supporting rope 3 and blocks 2 and 8 on the bracket 1. The greater the multiplicity of the chain hoist, the less will be the force on the supporting rope 3 from the weight of the product 12 and the load carrying carrier 6 and the smaller the difference of the indicated angles bracket. But with an increase in the multiplicity of the chain hoist, the length of its branches and, consequently, the response time of the cotton organ, increases. The subject matter of the invention 1. A hinged device to a crane for placing cargo in hard-to-reach places, including a load-carrying lever with a gripping body, mounted on a cargo suspension, hinged by means of a supporting rope on a lifting hook — a mechanism that, in order to increase productivity, improve conditions labor, and the expansion of the technology of application of the device, the cargo suspension is made in the form of an L-shaped bracket pivotally connected to the load-carrying lever and connected to it. formed by supporting rope. 2. The device according to claim 1, characterized in that, in order to ensure its stability during operation, the bracket is made with two points of support. 3. The device according to claim 1, characterized in that, in order to ensure the possibility of fixing the gripping body in extreme positions, the load-carrying lever is provided with stops interacting with the bracket.
