[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a tower crown installation structure with the following beneficial effects:

[0018] 1. The two clamping blocks are driven to move by the rotation of the cylindrical gear, thereby assisting in fixing the first tower crown. The cylindrical rod is twisted by the wrench and the block. The rotation of the cylindrical rod drives the cylindrical gear to rotate. The rotation of the cylindrical gear drives the two racks to move relative to each other. The movement of the rack drives the clamping block to move through the connecting block. The clamping block moves and fits against the inner wall of the square groove of the first tower crown, thereby fixing the position of the first tower crown and facilitating the welding and fixation of the first tower crown.

[0019] 2. The cylindrical clamping rod is squeezed by moving the push block to move, thereby realizing the connection between the first tower crown and the second tower crown. The rotation of the cylindrical rod drives the screw to rotate through the first bevel gear and the second bevel gear. The rotation of the screw drives the push block to move. The movement of the push block pushes the inclined surface to move the inclined surface block. The movement of the inclined surface block drives the cylindrical clamping rod to move through the first tower crown, thereby realizing the connection between the first tower crown and the second tower crown.

[0020] 3. The cylindrical block is pulled into the limiting groove by moving the clamping block, thereby fixing the position of the cylindrical clamping rod. During the movement of the clamping block, the pull rope is pulled to move, and the movement of the pull rope drives the cylindrical block to move. During the movement of the cylindrical clamping rod, the cylindrical block moves at the same time. When the movement of the cylindrical clamping rod drives the limiting groove to move, the cylindrical hole is completely moved to the outside of the first tower crown, so that the cylindrical hole and the cylindrical block are aligned. The cylindrical block continues to move and is inserted into the cylindrical hole of the limiting groove, thereby fixing the position of the cylindrical clamping rod and improving the connection stability of the first tower crown and the second tower crown.

[0021] 4. The elastic force of spring 2 facilitates the movement and reset of the cylindrical block, and further facilitates the separation of the first tower crown and the second tower crown. During the movement of the cylindrical block, the square slider is driven to move along the guide rod. The movement of the square slider squeezes spring 2, causing spring 2 to generate elastic force. The elastic force of spring 2 facilitates the movement and reset of the cylindrical block. The movement and reset of the cylindrical block facilitates the movement and reset of the cylindrical clamping rod.

[0022] 5. The design of the second T-slot and the second T-slide block facilitates the stable movement of the push block. When the second tower crown is installed on the top of the first tower crown, the second T-slide block is installed inside the second T-slot of the square frame, thereby preventing the push block from rotating with the screw and improving the movement stability of the push block.

The design of the spring 16 facilitates the movement and reset of the inclined block 14 and the cylindrical clamping rod 15. A screw 18 is rotatably installed on the top of the base 3, and a push block 19 is installed on the outside of the screw 18 through a threaded connection. The design of the push block 19 facilitates the movement of the cylindrical clamping rod 15 by squeezing the inclined block 14.

[0033] The first and second bevel gears 32 and 33 are meshed with each other, and the design of the first and second bevel gears 32 and 33 facilitates the rotation of the cylindrical rod 5 to drive the screw 18 to rotate.

Two positioning pins 31 are symmetrically welded on the outside of the first tower crown 1, and a cylindrical block 25 is symmetrically slidably installed on the outside of the first tower crown 1. One end of the pull rope 24 passes through the two positioning pins 31 and is fixedly connected to the cylindrical block 25. The movement of the pull rope 24 drives the cylindrical block 25 to move. The other end of the pull rope 24 is respectively installed on the clamping block 9 by screws, so that it is convenient for the clamping block 9 to move and pull the pull rope 24 to move. A limiting groove 26 is processed at one end of the cylindrical clamping rod 15, and the cylindrical block 25 is installed inside the limiting groove 26, so as to facilitate fixing the position of the cylindrical clamping rod 15.

[0035] The working principle of this embodiment is as follows: when the first tower crown 1 and the second tower crown 2 need to be installed, the first tower crown 1 is first installed on the base 3, so that the hollow rod 4 fits against the inner wall of the first tower crown 1, and the clamping block 9 is installed inside the square groove. The second tower crown 2 is installed on the top of the first tower crown 1, and then the square frame 12 is installed inside the second tower crown 2. At the same time, the top of the second T-shaped slider on the push block 19 is installed inside the second T-shaped groove 21 inside the square frame 12. Then, the cylindrical rod 5 is screwed by the wrench and the block 34. The rotation of the cylindrical rod 5 drives the cylindrical gear 6 to rotate. The rotation of the cylindrical gear 6 drives the two racks 7 to move relative to each other. The movement of the rack 7 drives the clamping block 9 to move through the connecting block 8. The clamping block 9 moves and fits into the inner wall of the square groove of the first tower crown 1, thereby fixing the position of the first tower crown 1, and the cylindrical rod 5 rotates to drive the screw 18 to rotate through the first bevel gear 32 and the second bevel gear 33, and the rotation of the screw 18 drives the push block 19 to move, and the push block 19 moves through the inclined surface to push the inclined surface block 14 to move, and the movement of the inclined surface block 14 drives the cylindrical clamping rod 15 to move through the first tower crown 1, and then the push block 19 fits into the plane position of the inclined surface block 14, and thus will not continue to push the cylindrical clamping rod 15 to move. During the movement of the cylindrical clamping rod 15, the spring 16 is squeezed, so that the spring 16 generates elastic force, and the elastic force of the spring 16 facilitates the movement and reset of the cylindrical clamping rod 15 and the inclined surface block 14.

[0036] During the movement of the clamping block 9, the pull rope 24 is pulled to move, and the movement of the pull rope 24 drives the cylindrical block 25 to move. During the movement of the cylindrical clamping rod 15, the cylindrical block 25 moves at the same time. When the cylindrical clamping rod 15 moves, it drives the limiting groove 26 to move, so that the cylindrical hole is completely moved to the outside of the first tower crown 1, so that the cylindrical hole and the cylindrical block 25 are aligned, and the cylindrical block 25 continues to move and inserts into the cylindrical hole of the limiting groove 26, thereby fixing the position of the cylindrical clamping rod 15, improving the stability of the connection between the first tower crown 1 and the second tower crown 2, and during the movement of the cylindrical block 25, it drives the square slider 29 to move along the guide rod 28. The square slider 29 moves to squeeze the spring 2 30, so that the spring 2 30 generates elastic force. The elastic force of the spring 2 30 facilitates the movement and reset of the cylindrical block 25.
