Description
Technical Field
The utility model relates to the technical field of vibration tests, in particular to a modular assembly type hydraulic vibration table capable of being vertically and horizontally switched.
Background
The hydraulic vibration table is an environmental mechanics test device, has the characteristics of heavy load, low working frequency, large working displacement and the like, and is widely applied to vibration simulation tests in the industries of aviation, ships, automobiles, electronic communication, instruments and meters and the like.
The common structural forms of the present hydraulic vibration table mainly include a vertical type, a horizontal type and a vertical and horizontal integrated type (turning switching type). The vertical and horizontal integrated hydraulic vibration table can realize the switching between vertical and horizontal stations by turning over the vibration exciter so as to realize the vibration in vertical and horizontal directions, namely, the functions of vertical and horizontal equipment are realized by one set of equipment.
Although the equipment cost is low, the following problems are found in the long-term use process:
the existing vertical and horizontal switching type hydraulic vibration table is not provided with a guide mechanism in the vertical vibration direction, and the vibration exciter adopts a static pressure guide technology for realizing high-frequency vibration, so that the vibration exciter can freely rotate in the axial direction, and the table body can rotate in the axial direction when being overturned to the vertical direction for vibration, but most of vertical vibration tests do not allow additional rotation components, so that part of vertical vibration tests cannot be smoothly carried out.
Although the existing vertical and horizontal overturning switching type hydraulic vibration table can realize vibration in two directions, the vibration can be smoothly completed by matching with special devices such as a crane and the like in the overturning switching process, the operation process is complicated, and the requirement on site matching is high, so that the equipment is limited in use.

For example, the hydrostatic guideway of the horizontal table is directly mounted on the base, which is a base of the vibration table and a part of the horizontal sliding table, so that the base and the horizontal sliding table cannot form two independent parts.
Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
