Description

Изобретение относитс к испытани м крупногабаритных цилиндрических сосудов, например, на внутреннее давление или внешнее механическое усилие при низких температурах и может быть использовано при испытани х сосудов в цеховых услови х.The invention relates to testing large-sized cylindrical vessels, for example, internal pressure or external mechanical force at low temperatures and can be used when testing vessels in shop conditions.

Известен способ установки цилиндрических сосудов в испытательную камеру , заключающийс в том, что сосуд размещают вертикально, поднимают, подвод т к открытой сверху испытательной камере и опускают в нее С 1Известный способ предназначен дл установки малогабаритных сосудов, размещение которых в испытательной камере (бронекамере, криостате и т.п.) осуществл ют вручную или при , помощи простейших приспособлений, поэтому использовать указанный способ в услови х промышленных цехов дл установки крупногабаритных сосудов нельз . При использовании дл этих целей „подъемно-транспортного оборудовани высота испытуемых сосудов лимитирована рассто нием между. верхним торцом испытательной камеры и подкрановыми пут ми.A known method of installing cylindrical vessels into a test chamber is that the vessel is placed vertically, raised, brought to the test chamber open at the top and lowered into it. C 1 A well-known method is designed to install small vessels that are placed in the test chamber (armored chamber, cryostat and etc.) is carried out manually or with the help of the simplest devices, therefore it is not possible to use this method in the conditions of industrial workshops for installing large vessels. When using for this purpose “lifting and transport equipment, the height of the test vessels is limited by the distance between. upper end of the test chamber and crane runways.

Цель изобретени - расширение номенклатуры испытуемых сосудов путем использовани пространства цеха над подкрановыми пут ми при установ ке крупногабаритных сосудов с помощью кранов в цеховых услови х.The purpose of the invention is to expand the range of test vessels by using the space of the workshop above the crane runways when installing large vessels with cranes in the workshop conditions.

Дл достижени указанной цели в способе установки цилиндрических сосудов в испытательную камеру, заключающемс в том, что сосуд размещают вертикально, поднимают, подво10 д т к открытой сверху испытательной камере и опускают в нее, используют траверсу, которой охватывают сосуд. и закрепл ют на его верхнем опорном по се, соедин ют траверсу с захвата15 ми двух кранов, установленных на подкрановых пут х, ниже верхнего опорного по са сосуда, но выше цент-. ра т жести системы сосуд-траверса, подъем сосуда осуществл ют между To achieve this goal, in the method of installing cylindrical vessels into the test chamber, the vessel is placed vertically, lifted up, connected to the test chamber opened from above and lowered into it, use the traverse which surrounds the vessel. and secured to its upper support leg, connect the yoke with grips of two cranes mounted on the crane runways, lower than the upper support leg of the vessel, but higher than the center. races of vessel-traverse system, vessel lifting is carried out between

Claims

The method is based on the fact that there is considerable space above the crane runways to the upper workshop ceiling, which can be useful. use when lifting large-sized vessels. CX method: cv is as follows. An upright cylindrical vessel is put on a traverse that encloses it, the upper part of which is fixed on the upper support of the vessel by means of a technological ring mounted on it. To the lower part of the crosspiece, the grips of two bridge cranes are connected, with the attachment points of the grips being located above the center of gravity of the vessel-traverse system, but lower than the upper support of the vessel. The vessel is lifted by two synchronously operating bridge cranes between and parallel paths to the level of excess of the new ways by the upper end of the vessel by 0.5-3.5 times the diameter of the vessel. At this height, the vessel is led to the test zone and stopped by an open-top test chamber. Then the vessel is lowered into the chamber up to the level of the lower end of the support vessel in the chamber intended for positioning the vessel 1-4 times the diameter of the vessel, while the lower surface of the enclosing crosshead is installed on the supports provided for it. The crane grips are uncoupled from the overhead rail. Another free bar is attached to the free parts of the technological ring, the external dimensions of which are less than the internal diameter of the surrounding grass. An additional spreader is connected to the grab of a crane, the knots of fastening the process ring to the embracing spindle are taken out of engagement, and the vessel is lowered into the test chamber. Uncoupling and removing the additional, and then covering the traverse, and then proceed to the test. Using the invention allows to expand the range of test vessels by using the space of the workshop above the crane. the way when lifting large vessels with bridge cranes. Claims The method of installation of cylindrical vessels into a test chamber consists in placing the vessel vertically, raising it, leading to the test chamber open at the top and lowering into it, characterized in that, in order to expand the range of test vessels mx by. using the workshop space above the crane runways when installing large vessels with the help of cranes in the workshop conditions, use the traverse, which is enclosed in the vessel and fixed to its upper support section, connect the traverse with the grips of two cranes mounted on the crane tracks , below the upper support of the vessel, but above the center of gravity of the vessel – jib system, the vessel is lifted between the crane runways to the level of the vessel’s excess by 0.5-3.5 lowering the vessel into the chamber disconnects it from the traverse.
