[0022] refer to Figure 1 , 2 , 3 and 4, detailing embodiments of replacing bolts for connection in truss towers:

[0023] A truss tower bolt replacement device includes a threaded sleeve 21 that passes through a through hole that overlaps a truss I11 and a truss II12, and a connecting rod 31 that is threadedly connected to the threaded sleeve 21. The truss I11 and the truss II12 are fixedly connected by the threaded connection between the threaded sleeve 21 and the connecting rod 31. A step sleeve I22 is provided on the threaded sleeve 21, and a step sleeve II32 corresponding to the step sleeve I22 is provided on the connecting rod 31, so that through holes of different diameters on the truss I11 and the truss II12 can be connected by the step sleeve I22 and the corresponding step sleeve II32.

[0024] refer to Figure 2 , 3 4, detailed description of the embodiment of the connection between the threaded sleeve 21 and the connecting rod 31:

[0025] A threaded hole 23 is processed in the middle of the threaded sleeve 21, and a threaded rod 33 connected to the threaded hole 23 is processed on the connecting rod 31. The threaded sleeve 21 and the connecting rod 31 are connected through the threaded connection between the threaded rod 33 and the threaded hole 23, thereby achieving a fixed connection between the truss I11 and the truss II12.

[0026] refer to Figure 5 , an embodiment of the structure of the connecting threaded hole 23 is described in detail:

[0027] The threaded hole 23 is a threaded through hole, so that the connection can be achieved by screwing the threaded rod 33 into the threaded hole 23 , and the threaded hole 23 of the threaded through hole can ensure the strength of the threaded sleeve 21 during connection.

[0028] refer to Figure 6 and 7 , detailed description of the embodiment of reducing the cost of the threaded sleeve 21:

[0029] The threaded hole 23 is a stepped hole, which can ensure the strength of the threaded sleeve 21 and the stepped sleeve I 22 while reducing the use of raw materials, thereby saving costs. A stepped hole can also be processed at the position of the connecting rod 31 corresponding to the stepped sleeve II 32, thereby reducing the use of raw materials and saving costs.

[0030] refer to Figure 5 , the embodiment of driving the threaded sleeve 21 to rotate is described in detail:

[0031] The end of the threaded sleeve 21 is provided with a turning handle Ⅰ24 , so that the threaded sleeve 21 can be driven to rotate by the turning handle Ⅰ24 , thereby increasing the convenience of rotating the threaded sleeve 21 .

[0032] refer to Figure 8 , an embodiment of driving the connecting rod 31 to rotate is described in detail:

[0033] The end of the connecting rod 31 is provided with a turning handle II 34 , so that the connecting rod 31 can be driven to rotate by the turning handle II 34 , thereby increasing the convenience of rotating the connecting rod 31 .

[0034] refer to Figure 4 and 8 , detailed description of an embodiment of increasing the fit of the step sleeve I 22 and the step sleeve II 32 in connecting the truss tower:

[0035] The step sleeve I 22 is provided with a cutter groove at the diameter change position. The step sleeve II 32 is provided with a cutter groove at the diameter change position, so that the step sleeve I 22 and the step sleeve II 32 can fit the truss through the cutter groove to ensure the stability of the connection to the truss tower.

[0036] refer to Figure 4 , details the embodiments of truss connection through holes of different diameters:

[0037] The diameter of the step sleeve I 22 decreases from the end away from the connecting rod 31 to the end close to the connecting rod 31. The diameter of the step sleeve II 32 decreases from the end away from the threaded sleeve 21 to the end close to the threaded sleeve 21. This ensures that the step sleeve I 22 and the step sleeve II 32 can pass through the through hole one by one, so that the trusses are finally connected through the corresponding diameters of the step sleeve I 22 and the step sleeve II 32.
