Through the coordinated use of the reinforcing web plate 10, the upper web rod 11, the lower web rod 12 and the transverse web rod 13, the connection between the main limbs 1 and the main limbs 1 can be made more stable, thereby making the standard section more secure when connected.

[0026] Example 2:

[0027] Figure 1-5This invention illustrates a standard section connection and reinforcement structure for a tower crane according to an embodiment of the present invention. It includes: four main limbs 1; each of the four main limbs 1 has a positioning groove 2 fixedly connected to its bottom cavity by bolts; each of the four main limbs 1 has a support plate 3 fixedly connected to its top cavity by bolts; two connecting blocks 4 are welded to the top of the support plate 3; rubber sleeves 5 are fitted onto the surfaces of the two connecting blocks 4; partition plates 6 are welded to the inner cavity of the positioning grooves 2; threaded holes are opened on the surfaces of the connecting blocks 4, rubber sleeves 5, and partition plates 6; bolts 7 are threadedly connected to the inner cavities of the threaded holes; and the surface of the bolts 7... The threaded connection is provided with a nut 8. The surface of the reinforcing web plate 10 is fixedly connected to a transverse web member 13 by bolts. The upper web member 11, lower web member 12 and transverse web member 13 are all fixedly connected to the adjacent main limb 1 by bolts. The bottom of the four main limbs 1 are all fixedly connected to a transverse plate 14 by bolts. A stiffening plate 15 is welded between the bottom of the support plate 3 and the inner wall of the main limb 1. By setting the stiffening plate 15, the support plate 3 can obtain an auxiliary support force in the inner cavity of the main limb 1, which can make the support plate 3 more firmly fixed to the inner wall of the main limb 1.

[0028] Working principle: When using this utility model, the user fixes the positioning groove 2 and the support plate 3 to the upper and lower sides of the inner cavity of the main limb 1. Then, the positioning groove 2 is fastened to the top of the support plate 3 from top to bottom, so that the connecting block 4 and the rubber sleeve 5 slide into the inner cavity of the positioning groove 2. At the same time, the rubber sleeve 5 can make the contact between the connecting block 4 and the inner cavity of the positioning groove 2 tighter, thus making the connection between the positioning groove 2 and the connecting block 4 more secure. Then, the main limb 1, the positioning groove 2, and the connecting block 4 are fixedly connected by bolts 7 and nuts 8, so that the main limb 1 is spliced ​​and fixed to the main limb 1 from top to bottom, thus making the upper and lower connection between the main limb 1 more secure. This makes the connection of each standard section more solid, so that the overall structure after the standard sections are connected can be more stable.

[0029] In summary, this tower crane standard section connection reinforcement structure uses a top-to-bottom approach to fasten the positioning groove 2 to the top of the support plate 3, allowing the connecting block 4 and the rubber sleeve 5 to slide into the inner cavity of the positioning groove 2. Simultaneously, the rubber sleeve 5 ensures a tighter contact between the connecting block 4 and the inner cavity of the positioning groove 2, thus achieving a more secure connection between the standard sections and a more stable overall structure after the standard sections are connected.
