[0012] 1. By providing a first platform plate and a second platform plate in the tower barrel, and connecting the first platform plate and the second platform plate through an openable limiting connecting member, the first platform plate and the second platform plate can be connected into a whole to form a maintenance platform, or the first platform plate and the second platform plate can be separated. In addition, the first platform plate and the second platform plate can be slidably connected to the inner wall of the tower barrel, so that the heights of the first platform plate and the second platform plate can be flexibly adjusted up and down according to the height of the maintenance position, and the application is more flexible. In addition, both the first platform plate and the second platform plate can be hingedly connected to the sliding member in a flipable manner. When the first platform plate and the second platform slide up and down and interfere with other components in the tower barrel during the sliding process, the limiting connecting member can be opened and the first platform and the second platform can be flipped to avoid other components in the tower barrel, ensuring the normal use of the first platform plate and the second platform plate.

[0013] 2. By providing a locking member on the protruding block that can lock the sliding block, when the locking member is locked, the protruding block can be locked on the sliding block to prevent the random flipping of the protruding block and the sliding block. In addition, after the locking member is opened, the first platform plate and the second platform plate can be flipped.

[0014] 3. By setting the locking member as the structure of the first electric push rod and the first limiting groove, when the piston rod of the first electric push rod extends into the first limiting groove, the protruding block and the sliding block can be limited and locked, and when the piston rod of the first electric push rod retracts from the first limiting groove, the locking of the protruding block and the sliding block is released.

[0026] An embodiment of the present utility model discloses a tower barrel maintenance platform. Referring to Figure 2 and Figure 3 , a tower barrel maintenance platform is provided inside the tower barrel 1, including a semi - circular first platform plate 2 and a semi - circular second platform plate 3. A hole groove 13 that can avoid the maintenance ladder 14 is provided on the first platform plate 2. A plurality of weight reduction holes 5 are provided on the first platform plate 2 and the second platform plate 3. The first platform plate 2 and the second platform plate 3 are slidably arranged on the inner wall of the tower barrel 1 through a plurality of sliding members, and both the first platform plate 2 and the second platform plate 3 are hingedly connected to the sliding members in a rotatable manner, and the first platform plate 2 and the second platform plate 3 are connected by an openable limiting connecting member. A stepping motor 4 for driving their sliding is provided on the first platform plate 2 and the second platform plate 3.

[0027] Specifically, as Figure 4 andFigure 6 As shown, each of the sliding members includes a slider 6, and a chute 7 for sliding cooperation with the slider 6 in the vertical direction is provided on the inner wall of the tower barrel 1. A protruding block 8 is provided at a position corresponding to the slider 6 on each of the first platform plate 2 and the second platform plate 3. The protruding block 8 is hingedly connected to the slider 6 through a hinge shaft 15, and a locking member for locking the slider 6 is provided on the protruding block 8. When the locking member is locked, the protruding block 8 can be locked on the slider 6 to prevent the random flipping of the protruding block 8 and the slider 6. In addition, after the locking member is opened, the first platform plate 2 and the second platform plate 3 can be flipped. Specifically, the locking member includes a first electric push rod 9, and the body of the first electric push rod 9 is embedded in the protruding block 8. A first limiting groove 10 corresponding to the piston rod of the first electric push rod 9 is provided on the slider 6. When the piston rod of the first electric push rod 9 extends into the first limiting groove 10, the protruding block 8 and the slider 6 can be limited and locked. When the piston rod of the first electric push rod 9 retracts from the first limiting groove 10, the locking of the protruding block 8 and the slider 6 is released.

[0028] In this embodiment, as Figure 5 and Figure 7 shown, the limiting connecting member includes a second electric push rod 11, and the body of the second electric push rod 11 is embedded in the second platform plate 3. A second limiting groove 12 corresponding to the piston rod of the second electric push rod 11 is provided on the first platform plate 2.
