[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] like Figure 1As shown, a pneumatic gear ring locking mechanism comprises an upper flange 1, a lower flange 2, a sealing gasket 3, a gear ring 4, a bearing 5, a cylinder 6 and a cylinder push rod 7, the upper flange 1 and the lower flange 2 are respectively connected to the components to be connected, the lower surface of the upper flange 1 is in contact with the upper surface of the lower flange 2, the sealing gasket 3 is arranged between the upper flange 1 and the lower flange 2, the upper part of the gear ring 4 is connected to the upper flange 1, the cylinder 6 is fixed on the upper flange 1, the cylinder push rod 7 is connected to the gear ring 4, the upper flange 1 and the gear ring 4 are provided with through holes, and the upper flange 1 and the gear ring 4 are connected through the bearing 5; as shown Figure 2 and Figure 3 As shown, the side wall of the lower flange 2 is a toothed structure, a first trapezoidal bevel block 201 is arranged on the lower surface, the gear ring 4 is an annular structure, the inner surface of the gear ring 4 is a toothed structure, and a second trapezoidal bevel block 401 is arranged on the upper surface. After the pneumatic gear ring locking mechanism is installed in place, the cylinder push rod 7 is driven by the cylinder 6 to drive the gear ring 4 to rotate, and the first trapezoidal bevel block 201 and the second trapezoidal bevel block 401 cooperate to complete the locking.

[0024] The first trapezoidal inclined block 201 and the second trapezoidal inclined block 401 are connected to the lower flange 2 and the gear ring 4 respectively by bolts, the cylinder push rod 7 and the gear ring 4 are connected in an articulated manner, and the cylinder 6 and the upper flange 1 are connected by bolts.

[0025] like Figure 4 and Figure 5 As shown, the installation method of the pneumatic gear ring locking mechanism is as follows: match the tooth structure of the gear ring 4 with the tooth groove of the lower flange 2, push the upper flange 1 and the lower flange 2 into place, connect the air source to the cylinder 6, push the cylinder push rod 7 to make a linear motion, and drive the gear ring 4 to rotate along the upper flange 1. When the tooth structure of the gear ring 4 overlaps with the tooth structure of the lower flange 2, the second trapezoidal bevel block 401 and the first trapezoidal bevel block 201 fit together to complete the locking; when the locking needs to be released, disconnect the air source of the cylinder 6, and the cylinder 6 is acted upon by the air to retract the cylinder push rod 7, drive the gear ring 4 to rotate, and the second trapezoidal bevel block 401 and the first trapezoidal bevel block 201 are separated from each other to complete the locking release.
