Problems solved by technology
[0003] Because of the particularity of its equipment and the use environment, a series of problems will appear 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.

Embodiment Construction
[0032] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0033] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0034] Such as figure 1 , figure 2 As shown, the locking mechanism includes a lock hook 1, a V-shaped clamping plate 2, a base 3, a block 4, a first pin 5, a U-shaped clip 6, a cylinder 7, a second pin 8, a top pin 9, and a vertical plate 10. The elastic member 11, the pillar support 12, the backing plate 13, and the bolt 14 constitute a mechanism with positioning and locking functions through these mechanical structures.

The invention discloses a docking, positioning and locking mechanism for a large-scale device, which comprises: a base, a main support arranged on the base, a top post support, and a top post, the top post can slide in the cavity of the top post support, and the top post An elastic piece is arranged between the end surface and the end surface of the top column bracket; the base is provided with a V-shaped clamping plate and a lock hook, and the tail ends of the V-shaped clamping plate and the lock hook are connected with the second column pin arranged on the base, and around the Rotate with the second column pin, the side plate of the lock hook is connected with the output end of the cylinder through the first column pin; the present invention relies on the position sensing of the cylinder itself to control the stroke of the telescopic rod of the cylinder to realize the rotational movement of the lock hook; the lock hook and the V The glyph lock forms a closed loop, mechanical limit, no other limit sensors are needed, the control system is simple, and the 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...
