[0041] Example 1

[0042] A tower assembly platform lifting system, such as Figure 1-7 As shown, it is installed at the four corners of the tower body 1. The tower body 1 is connected with a plurality of brackets 6 by bolts, which are used to connect the lifting device 3 and the hoisting device 2 with the tower body 1. The lifting system includes:

[0043] A lifting device 3 is fixed at the bottom of the tower body 1;

[0044] The guide device 4 comprises a guide rod 41 and a guide rod mounting seat 42 connected to the upper and lower ends of the guide rod 41, wherein the guide rod mounting seat 42 is detachably connected to the tower body 1;

[0045] The hoisting device 2 is detachably connected to the tower body 1 and is rollingly connected to the guide rod 41;

[0046] The tower assembly platform 5 is fixed at the bottom of the hoisting device 2;

[0047] The lifting device 3 is connected to the hoisting device 2 , and lifts the hoisting device 2 to achieve synchronous lifting of the tower assembly platform 5 . During the lifting, the hoisting device 2 moves axially along the guide rod 41 .

[0048] When the lifting system of the present invention is lifting, the lifting device 3 provides power to lift the hoisting device 2, thereby realizing the synchronous lifting of the tower assembly platform 5. By setting the guide device 4 and utilizing the guide rod 41 to be rollingly connected with the hoisting device 2, when the hoisting device 2 and the tower assembly platform 5 are lifted synchronously, the hoisting device 2 can be stably lifted along the axial direction of the guide rod 41. The moving path of the hoisting device 2 is limited by the guide rod 41, thereby improving the lifting stability of the hoisting device 2 and the lower tower assembly platform 5. At the same time, it can ensure that the hoisting device 2 is accurately positioned with the hanger 6 after lifting, thereby making the positioning of the hoisting device 2 more accurate when fixed and the operation faster.

[0049] In one or more implementations of this embodiment, see Figure 4 , 67. The guide rod mounting seat 42 includes a first mounting plate 421, a connecting rod 422, a second mounting plate 423, a first V-shaped plate 424, a second V-shaped plate 425 and a strip plate 426. The first mounting plate 421 and the second mounting plate 423 are fixed by a connecting rod 422. The first V-shaped plate 424 is fixed on the first mounting plate 421. The second V-shaped plate 425 is fixed on the second mounting plate 423. The first V-shaped plate 424 and the second V-shaped plate 425 are both detachably connected with the strip plate 426. A connecting piece 427 is provided on the strip plate 426. The guide rod mounting seat 42 is connected to the tower body 1 via the connecting piece 427.

[0050] When installing the guide rod mounting seat 42, the two ends of the strip plate 426 are fixed to the first V-shaped plate 424 and the second V-shaped plate 425 by bolts, thereby enclosing a space in which the main material of the iron tower is located, and then the strip plate 426 is fixed to the main material of the iron tower by the connecting piece 427 to achieve the installation of the guide rod mounting seat 42.

[0051] The connecting member 427 can be configured as an ear plate with a through hole, or as Figure 7 As shown, the nut is welded on the strip plate 426 and connected to the main material of the tower by means of bolts passing therethrough.

[0052] Preferably, a reinforcing rod 428 is connected between the strips 426 of the first V-shaped plate 424 and the second V-shaped plate 425. The reinforcing rod 428 can improve the connection strength of the upper and lower V-shaped plates, thereby ensuring the reliability of the connection.

[0053] In one or more implementations of this embodiment, the guide rod mounting seat 42 is provided with a plug hole 46 for connecting with the guide rod 41, and a stop structure is provided at the end after both ends of the guide rod 41 pass through the plug hole 46. The purpose of providing the stop structure is to prevent the guide rod 41 from moving after being connected with the guide rod mounting seat 42.

[0054] See also Figure 7 The stopping structure includes a stopping ring 45. After the upper end of the guide rod 41 passes through the plug hole 46 of the guide rod mounting seat 42, a stopping ring 45 is arranged at the end. The setting of the stopping ring 45 can prevent the guide rod 41 from slipping out, thereby realizing the limiting of the upper end of the guide rod 41 and the guide rod mounting seat 42.

[0055] See also Figure 6 The stopping structure includes a plurality of stopping holes 43 opened in the lower portion of the guide rod. The lower end of the guide rod 41 extends outward after passing through the insertion hole 46 of the guide rod mounting seat 42. A fixing pin 44 is inserted into the stopping hole 43 of the outwardly extending guide rod 41, thereby realizing the limiting of the lower end of the guide rod 41 and the guide rod mounting seat 42.

[0056] In one or more implementations of this embodiment, see Figure 1 , 3 The lifting device 3 includes a winch body 31 and a winch mounting seat 32. The bottom of the winch body 31 is fixed to the winch mounting seat 32 by bolts. The winch mounting seat 32 is bolted to the bracket 6. The bracket 6 is installed at the bottom of the main material of the tower body 1, thereby realizing the connection between the lifting device 3 and the tower body 1, and realizing the lifting operation of the tower assembly platform 5 through the winch.

[0057] In one or more implementations of this embodiment, see Figure 1 , 3 4. The hoisting device 2 includes a crane body 21 and a crane mounting seat 22. The bottom of the crane body 21 is fixed to the crane mounting seat 22 by bolts. The crane mounting seat 22 is fixed to the bracket 6 by bolts. The bracket 6 is fixed to the main material of the tower body 1, thereby realizing the connection between the hoisting device 2 and the tower body 1. The crane body 21 is responsible for hoisting the tower materials for tower assembly, and at the same time assists in the installation and lifting of the guide device 4.

[0058] See also Figure 5 The four corners of the crane mounting seat 22 are provided with legs 23, a pair of rollers 24 are provided on the legs 23, and the guide rod 41 passes through the middle of the rollers 24. By providing the legs 23 at the four corners of the crane mounting seat 22 and using the rollers 24 to achieve rolling connection with the guide rod 41, when the hoisting device 2 and the tower assembly platform 5 are lifted by the winch, the guide rod 41 can limit the moving path of the hoisting device 2, thereby improving the lifting stability of the hoisting device 2 and ensuring that the hoisting device 2 is accurately positioned with the bracket 6 after being lifted, so that the hoisting device 2 is more accurately positioned when fixed and the operation is faster.

[0059] In one or more implementations of this embodiment, see Figure 1 The tower assembly platform 5 adopts a telescopic walkway, which is mainly used to provide a working platform for workers. It is connected and fixed to the crane mounting seat 22 at the four corners of the tower. The height is raised synchronously with the crane mounting seat 22. At the same time, the size of the walkway platform can be adjusted automatically as the cross-section of the tower changes.

[0063] (2) The second layer of tower materials is hoisted by a crane and the second layer is assembled. After the assembly is completed, the guide device 4, the hoisting device 2 and the tower assembly platform 5 are lifted and fixed, and then the third layer is hoisted and assembled. This cycle is repeated until the entire tower body 1 is assembled.

[0064] Among them, taking the lifting after the second layer is assembled as an example, the four lifting systems at the four corners work simultaneously. The specific lifting process is as follows:

[0065] (1) Lifting of the guide device 4: unlock the guide rod mounting seat 42 at the upper part of the guide rod 41, remove the fixing pin 44 at the position of the guide rod mounting seat 42 at the lower part of the guide rod 41, use a crane to lift the guide rod 41 and the upper guide rod mounting seat 42 to a suitable position on the second floor and fix them, then remove the guide rod mounting seat 42 at the lower part of the guide rod 41 and move it up to a suitable position and fix it, and insert the fixing pin 44 at the position where the guide rod 41 extends out of the lower guide rod mounting seat 42, and perform the same operation at the four corners of the tower body 1 at the same time, thereby completing the lifting and installation of the guide device 4; during the lifting process, the lifting mounting seat is always in rolling connection with the guide rod 41, that is, the guide rod 41 is always inserted into the rollers 24 of the four corner legs 23 of the crane mounting seat 22.

[0066] (2) Lifting of the tower assembly platform 5: Loosen the crane mounting seat 22 and the bracket 6, and use the winch to lift the lifting device 2 to the second-layer bracket 6. After it is in place, it is fixed to the bracket 6 to complete the lifting operation. During the lifting process, the crane mounting seat 22 is stably lifted upward along the guide rod 41 through the roller 24, and the guide rod 41 is used to limit the moving path of the lifting device 2, thereby improving the lifting stability of the lifting device 2 and the lower tower assembly platform 5. At the same time, it can ensure that the lifting device 2 is accurately positioned with the bracket 6 after lifting, so that the positioning of the lifting device 2 when fixed with the bracket 6 is more accurate and the operation is faster.
