Embodiment Construction

[0019] In order to solve the technical problem of the low reliability of the existing roller and ball interlayer sliding methods used in the laminated shear box, an embodiment of the present invention provides an interlayer sliding device for the laminated shear box, The general idea is as follows:

[0020] The interlayer sliding device is composed of guide grooves, fixing grooves and sliding components. The guide grooves are fixed on the bottom of the upper steel frame, the fixing grooves are fixed on the top of the lower steel frame, and the sliding components are set in the fixing grooves.

[0021] Through the interlayer sliding device of the above structure, before the stacked shear box shaking table test, the fixing groove needs to be inserted into the guide groove when the two layers of steel frames are superimposed, and driven by the sliding component, the adjacent two layers of steel frames The relative slip between them will follow the track in the guide groove, reali...

Abstract

The invention discloses an interlamination sliding device of a laminated shearing box. The laminated shearing box comprises at least two layers of superposed steel frames. The interlamination sliding device includes guiding grooves, fixing grooves and sliding assemblies; the guiding grooves are fixed at the bottom of the upper-layer steel frame; the fixing grooves is fixed at the top of the lower-layer steel frame; the sliding assemblies are arranged in the fixing grooves; when the two layers of steel frames are superposed, the fixing grooves are inserted into the guiding grooves; and the sliding assemblies drive the upper-layer steel frame to move along the guiding grooves, so that the two layers of steel frames can slide horizontally relative to each other in a directional manner. With the interlamination sliding device adopted, the technical problem of low reliability of existing roller type and ball type interlamination sliding modes used in the laminated shearing box can be solved, and safe and reliable use and stable performance of the laminated shearing box can be realized.

Description

technical field [0001] The invention relates to the anti-seismic technical field of oil and gas pipelines, in particular to an interlayer sliding device of a laminated shear box. Background technique [0002] Earthquake simulation shaking table is one of the important test equipment for earthquake engineering research work, mainly used to simulate the earthquake environment that buildings and structures may encounter during the use phase, so as to evaluate their vibration resistance, reliability and integrity. [0003] At present, there are roughly three types of soil boxes commonly used in shaking table tests: rigid boxes, flexible boxes, and shear boxes. The shear box is usually composed of 10 to 20 layers of steel frames, and the adjacent two layers can slide relative to each other. It is better than the rigid box and the flexible box in simulating the shear deformation of the soil, and is considered to be an ideal model box. At present, most shear boxes generally use ro...
