However, since the release of the deformation displacement by the central support is generally along the horizontal direction, and the scale of the large-scale test device is large, considering factors such as load bearing and margin, the central support often occupies a large area, the construction cost is high, and it will affect the surrounding equipment. the construction of

Embodiment Construction
[0022] The present invention will be further explained below in conjunction with accompanying drawing
[0023] The present invention provides a central positioning structure of a large-scale test device. The structure includes a support base 1 on which two connection lugs 3 are provided, and a connection shaft 2 is provided between the support base 1 and the connection lugs 3 . The support base 1 is a steel support, which connects the test equipment 5 and the civil foundation, and undertakes and transmits the gravity and support reaction force of the upper test device. The connection lug 3 is a steel structure that is not easily deformed. The side of the connection lug 3 is fixed to the test device 5, and the lower surface plane is in contact with the connection shaft for transmitting the force and displacement generated during the operation of the test device. The connecting shaft 2 is a semi-cylindrical structure, made of wear-resistant metal material, the upper surface is f...

The invention provides a central positioning structure of a large-scale test device. The structure includes a supporting base, two connecting lugs are arranged on the supporting base, and a connecting rotating shaft is arranged between the supporting base and the connecting lugs. The central positioning structure of the large-scale test device provided by the present invention can ensure that the original position of the center line of the test device can still be ensured compared with the traditional saddle support when the operating temperature of large-scale test pressure vessel equipment changes greatly. The connected test devices are connected reliably without bending and other destructive phenomena. The design of the connecting shaft compensates for the possible angular deflection of the lugs and prevents the problem of local stress concentration.
Description
technical field [0001] The invention belongs to the field of test equipment pressure vessels, and in particular relates to a center positioning structure of a large test device Background technique [0002] At present, support is an important part of general large-scale test devices. At present, most large-scale test devices in the industry adopt the form of saddle supports, which are mainly composed of backing plates, bottom plates, webs, and ribs. Saddle supports have The structure is simple, the stability is good, and the floor area is small, so it is widely used, but the centering effect of the saddle support is poor for the test device that generates temperature deformation. [0003] For the situation where the temperature of general equipment changes greatly, most of them adopt the form of central support, whose free sliding can release the displacement caused by thermal deformation, and can better ensure that the center of the equipment remains unchanged. However, si...
