Abstract

The invention discloses a double-scissors type rotary lifting table. According to the double-scissors type rotary lifting table, a rotary table body is installed above an upper base, capable of rotating relative to the upper base and used for bearing to-be-borne objects, the upper base is installed at the top end of a double-scissors lifting mechanism and used for bearing the rotary table body; the double-scissors lifting mechanism is installed above a lower base and used for driving the upper base and the rotary table body to vertically ascend and descend; the double-scissors lifting mechanism controls two ball screws to rotate at the same time so as to make two ball nut bases in threaded connection with the two ball screws move away from or get close to a middle bearing base at the sametime; the two ball nut bases drive scissor mechanisms connected with the two ball nut bases to achieve ascending / descending movement of a platform; and the lower base is used for bearing the rotary table body, the upper base and the double-scissors lifting mechanism. The double-scissors lifting structure is adopted, lateral movement in the platform lifting process is avoided, and stability of thelifting process is ensured.

Description

technical field [0001] The present invention relates to the technical field of rotary lifting platform, and more specifically, relates to a double-scissor type rotary lifting platform. Background technique [0002] The science and technology museum is a non-profit popular science education institution whose main function is exhibition education, and the exhibition display design is more important to the publicity effect of the science and technology museum. The display form of the exhibits in the Science and Technology Museum determines the teaching effect of the Science and Technology Museum. In view of the current development status of domestic science and technology museums, the exhibits of science and technology museums mainly adopt four forms: static, dynamic, situational and theater. Rotary lifting table is one of the most commonly used mechanical equipment in the dynamic display process of exhibits. It is used for all-round dynamic display of exhibits in conjunction ...
