Description

The utility model relates to test equipment designed to test heavy and bulky products, for example, a TUK transport and packaging set for storing and transporting spent nuclear fuel of a new design, to confirm compliance with regulatory documents, namely the requirements of the "Safety Rules for the Transport of Radioactive materials NP - 053-04 ".

The developed equipment is designed to carry out work using the mechanical testing installation of the test base of JSC Design Bureau of Special Engineering for the nuclear industry (2009 brochure), while the novelty of the product design necessitates the development of a new set of testing equipment that has significant distinguishing features from the proposed standard a set of equipment for conducting impact tests on the specified installation.

Tests simulate extreme situations, the appearance of which is possible during the operation of the product. Tests include throwing the product from a height from vertical and horizontal positions onto a steel plate, throwing the product from a height onto a pin, as well as transport tests involving transportation of the product from the manufacturer to the test site.

As an analogue, the well-known "Traverse of heavy carrying capacity" can be considered (RF patent No. 57714 dated May 16, 2006, published on October 27, 2006 Bull. No. 30).

The heavy-duty traverse contains a cargo beam and slings mounted on the cargo beam, while the cargo element for hanging on the hook of the lifting means is detachable from the cargo beam, fixed in the center of the latter using smooth fingers in the cheeks of the cargo beam and is removable.

As an analogue, one can also consider the suspension of MBK (metal-concrete container) SM-783. SbOOSB developed by JSC Design Bureau of Special Engineering for the nuclear industry (2009 brochure).

The suspension is a welded metal structure with a lever-screw mechanism for simultaneously bringing and releasing two gripping pins into the corresponding holes on the MBK case. The lever-screw mechanism is equipped with a ratchet mechanism, eliminating the unauthorized direction of movement of the pins from the screw drive. The final positions "Retracted" and "Failed up" of the pins are controlled by pointers in the form of arrows in coincidence with the corresponding grooves.

The pendant is equipped with a welded earring, with which it is hung on the gripping body of the crane.

Both of these analog designs are not designed to be used with the existing undocking device at the KBSM OJSC installation.

The technical task is to develop a set of equipment for testing a product of a new design, allowing various types of tests to confirm it and impact-resistant characteristics.

The problem is solved by a set of equipment for testing the product, which includes a traverse for vertical hanging and dumping the product, the kit additionally contains a traverse for horizontal hanging and dumping the product, a support with a lodgement for carrying out transport tests and transporting the product in a horizontal position, with each traverse equipped with an earring under the undocking device for installing mechanical tests, and a device for carrying out transport tests and transporting the product horizontally In the new position it is used at the same time to transfer the product from a vertical position to a horizontal position and vice versa, while the support and tool tray are mounted on the rollers.

The traverse for vertical hanging and dumping of the product contains a welded frame consisting of a beam and two side sections, in the lower part of each there are holes in which gripping trunnions are mounted, mounting brackets are fixed on the inner surfaces of the side sections in the area of the gripping trunnions, with which the traverse is fixed on the protruding the flanges of the socket sleeves of the product, providing initially the alignment of their axes with the axes of the gripping pins.

The traverse for horizontal hanging and dumping of the product contains a welded frame consisting of a beam and two side sections, each of which has an opening to which two detachable bandages are attached using fingers and adapters. The earring is two plates with grooves fastened together, into which a support sleeve is installed with conical surfaces of high hardness, based on the existing spherical washers of the undocking device.

The technical result is to ensure the reliability of the product during operation.
