Butt-jointing positioning and locking mechanism for large device

Abstract

The invention discloses a butt-jointing positioning and locking mechanism for a large device. The butt-jointing positioning and locking mechanism comprises a base, and further comprises a main bracket, a top column bracket and a top column which are arranged on the base; the top column can slide in a cavity of the top column bracket, and an elastic part is arranged between the end surface of the top column and the end surface of the top column bracket; and a V-shaped clamping plate and a lock hook are arranged on the base, the V-shaped clamping plate and the tail end of the lock hook are connected with a second column pin which is arranged on the base and rotate around the second column pin, and a side plate of the lock hook is connected with an output end of an air cylinder through a first column pin. According to the butt-jointing positioning and locking mechanism, the stroke of a telescopic rod of the air cylinder is controlled relying on the position sensing of the air cylinder, and the rotation movement of the lock hook is achieved; and a closed circuit is formed by the lock hook and a V-shaped clamping lock, mechanical limiting is achieved without other limiting sensors, thecontrol system is simple, and positioning is accurate and reliable.

Description

technical field [0001] The invention relates to the field of large-scale mechanical equipment, in particular to a mechanism for positioning and locking during the docking process of high-altitude large-scale equipment. Background technique [0002] In the wind tunnel test, different test equipment needs to be replaced according to the different requirements of different tests. The movable transport equipment transports the test equipment from the place where it is placed to the front end of the test section, and puts it into the test section through the lifting device track lifting and translation . Especially in large-scale wind tunnel tests, the connection between different test equipment and devices must ensure the accuracy of their positions. Because of the particularity of this type of test equipment, conventional methods of operation are performed manually, using locking devices or positioning devices for calibration. [0003] Because of the particularity of its equi...

AI Technical Summary

Problems solved by technology

[0003] Because of the particularity of its equipment and use environment, there will be a series of problems in the existing common locking and positioning devices. For example, during the wind tunnel test, the interconnected devices will experience certain vibrations when they are subjected to intense vibration. Mutual displacement, and this displacement will lead to the precision of the connection of the test equipment

[0004] Therefore, the currently commonly used positioning and locking mechanisms are basically unable to be applied to the docking of large-scale equipment in wind tunnels.
