Movable connection structure between vibration table body base and foundation

Abstract

A movable connection structure between a vibration table body base and a foundation is characterized in that the structure comprises mobile lifting mechanisms, a fixed mechanism, and foundation steel plates; each mobile lifting mechanism consists of a lifting mechanism and a moving mechanism, the lifting mechanism acts in the vertical direction, and the acting end of the lifting mechanism is connected with the moving mechanism through a guide structure; the rotating shafts of the rollers at the front end or / and rear end of the base are in transmission connection with the output shaft of a drive motor; the fixed mechanism includes locking plates fixedly connected with the base, and the locking plates are provided with locking holes; each foundation steel plate is provided with a locking slot along the motion trail of the corresponding locking holes; the locking plates and the locking slots are connected by bolt assemblies; when the bolt assemblies are unscrewed, the lifting mechanisms drive the rollers to extend downward out of the lower surfaces of the locking plates to move the vibration table body; and when the bolt assemblies are screwed, the vibration table body and the foundation steels plate are connected. The movable connection structure of the invention is convenient to adjust and reliable in use.

Description

technical field [0001] The invention relates to the field of vibrating table technology for environmental mechanics tests, in particular to a movable connection structure between the base of the vibrating table and the foundation, which can be used for the movement of a single vibrating table body, such as the three comprehensive tests of the vibrating table body entering and exiting the test chamber , It can also be used for the simultaneous vibration test of multiple shaking tables for long specimens. Background technique [0002] Electric vibration test bench (hereinafter referred to as electric vibration table) is a kind of equipment for vibration simulation test of products or components. Through such tests, the seismic performance of a product can be evaluated and a reasonable basis can be provided for assessing the quality of the product. Therefore, it is widely used In industries such as aerospace, aviation, shipbuilding, automobiles, electronics, communications, hom...

Problems solved by technology

In this patented technical solution, the amount of inflation and deflation of the airbag group is not easy to control, and in the support state, the height adjustment of the airbag group is not accurate enough, the height of the moving coil of the electric vibrating table will deviate, and the vibrating table will shake when it is working. Detrimental effect on the test (especially in the double vibration test)
