Through this technical scheme, change frock with aerogenerator pitch cylinder and pass through support 2 and connect in support 1, afterwards connect connecting piece 4 in round pin axle 11, wherein on the one hand, be connected driving piece 3 and connecting piece 4 through mounting 5, afterwards driving piece 3 can drive connecting piece 4 and round pin axle 11 and keep away from support 1 and remove, so that round pin axle 11 and support 1 separation, remove the restriction to the pitch cylinder, and then accomplish the demolish to the pitch cylinder, on the other hand, driving piece 3 can drive connecting piece 4 and round pin axle 11 and remove towards support 1, so that will become the pitch cylinder and install in support 1 through round pin axle 11, and then accomplish the installation to the pitch cylinder. Therefore, when the variable pitch cylinder is dismounted, the variable pitch cylinder and the support 1 are not required to be dismounted together, the workload is reduced, and the working efficiency is improved.
In some embodiments, as shown in fig. 1 and 2, the connecting member 4 includes a first threaded rod 41 and a threaded sleeve 42, one end of the first threaded rod 41 is screwed to the pin 11, the other end of the first threaded rod 41 remote from the pin 11 is screwed to the threaded sleeve 42, and the fixing member 5 detachably connects the driving member 3 and the threaded sleeve 42.
When the pitch cylinder needs to be disassembled, in the process of connecting the connecting piece 4 with the pin shaft 11, one end of the first threaded rod 41 is in threaded connection with the pin shaft 11, the threaded sleeve 42 is in threaded connection with the other end, far away from the pin shaft 11, of the first threaded rod 41, then the driving piece 3 and the threaded sleeve 42 are connected through the fixing piece 5, and the driving piece 3 can indirectly drive the first threaded rod 41 and the pin shaft 11 to move far away from the support 1 through the fixing piece 5 and the threaded sleeve 42.

And repeating the above process until the pitch cylinder can be mounted on the support 1 through the pin shaft 11, thereby completing the mounting of the pitch cylinder.
The fixing member 5 may be configured in any suitable manner, for example, in one embodiment, as shown in fig. 3 and 4, the fixing member 5 includes fixing rods 51, at least two fixing rods 51 are arranged at intervals along the circumference of the driving member 3, for example, three fixing rods 51 may be provided, one end of each fixing rod 51 is rotatably connected to the driving member 3, and the other end of each fixing rod 51, which is far away from the driving member 3, can be selectively abutted against or separated from the side, close to the support 1, of the threaded sleeve 42, so that the driving member 3 can drive the threaded sleeve 42 to move away from the support 1 by the fixing rods 51, or drive the threaded sleeve 42 to move towards the support 1 by the driving member 3.
In another embodiment, not shown, the fixing member 5 may be configured as, for example, a bolt, which penetrates through the threaded sleeve 42 and then is screwed to the driving member 3 to connect the threaded sleeve 42 to the driving member 3, which is not specifically limited in the present disclosure.

When the pitch cylinder needs to be disassembled, the driving piece 3 and the connecting piece 4 need to be connected through the fixing piece 5, the fixing rod 51 is rotated to the side, close to the support 1, of the threaded sleeve 42, which is far away from the driving piece 3, so that the driving piece 3 and the threaded sleeve 42 can be fixed by the fixing rod 51, and the driving piece 3 can indirectly drive the first threaded rod 41 and the pin shaft 11 to move towards the direction far away from the support 1 through the fixing rod 51 and the threaded sleeve 42.
When the pitch cylinder needs to be installed, the fixed rod 51 is rotated to the side, far away from the driving piece 3, of the threaded sleeve 42, which is close to the support 1, and the driving piece 3 directly acts on the threaded sleeve 42 to drive the first threaded rod 41 and the pin shaft 11 to move close to the support 1. Or, when the threaded sleeve 42 is required to be screwed in, the fixing rod 51 is rotated to the end far away from the driving member 3 and separated from the side of the threaded sleeve 42 close to the support 1, so that the connection effect of the fixing rod 51 to the driving member 3 and the threaded sleeve 42 is released, and the threaded sleeve 42 can be screwed in the first threaded rod 41.
It will be appreciated that the number of the fixing rods 51 is multiple, so that balance and stability of the driving member 3 in the process of indirectly driving the first threaded rod 41 and the pin 11 to move away from the support 1 through the fixing rods 51 and the threaded sleeve 42 can be improved.

When the pitch cylinder is required to be installed, the first rod 511 connected to the piston rod 312 is rotated until the other first rod 511 is separated from the threaded sleeve 42, so that the fixing effect of the piston rod 312 and the threaded sleeve 42 is released.
