[0026] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0027] First, it should be noted that the steel tower circumferential joint construction platform proposed in this application can be applied to the field of bridge construction platform technology. For example, for novel teardrop-shaped steel-concrete composite towers, the cross-sectional size of the steel tower varies. Existing steel tower circumferential joint construction platforms cannot change according to the cross-sectional size of the steel tower. Therefore, it is particularly important that the steel tower circumferential joint construction platform can adjust its distance from the steel tower according to the change in the cross-section of the steel tower.

[0028] According to one aspect of this application, a steel tower circumferential joint construction platform is provided. Figure 1This is a structural schematic diagram of a steel tower circumferential joint construction platform according to an embodiment of this application. Figure 2 This is a schematic cross-sectional view of the installation of the steel tower circumferential joint construction platform according to an embodiment of this application. Figure 3 This is a front view of the steel tower circumferential joint construction platform shown according to an embodiment of this application. Figure 4 This is a schematic diagram illustrating the installation of a steel tower circumferential joint construction platform according to an embodiment of this application. Figure 5 The following is a detailed description of the tie rod installation of the steel tower circumferential joint construction platform according to an embodiment of this application:

[0029] Please refer to Figures 1-4 According to one aspect of the embodiments of this application, a steel tower circumferential joint construction platform is provided. The steel tower circumferential joint construction platform includes a main hanging basket 10, a tail hanging basket 20, a slide 30, and a guardrail 40. The main hanging basket 10 surrounds the steel tower 70 and is fixed to the steel tower 70. The main hanging basket 10 is used to support workers to work on the steel tower 70. The tail hanging basket 20 is connected to the main hanging basket 10 and is used to support workers to work on the steel tower 70. The slide 30 is disposed on the tail hanging basket 20 and can slide along the tail hanging basket 20. The slide 30 and the main hanging basket 10 surround the steel tower 70. The guardrail 40 is disposed on the inner and outer sides of the main hanging basket 10 and the tail hanging basket 20. The main hanging basket 10, the tail hanging basket 20, and the guardrail 40 surround the steel tower 70 to form a U-shaped corridor for workers to walk on.

[0030] In this application, the main hanging basket 10 and the tail hanging basket 20 are used to support workers standing during construction. To accommodate changes in the cross-section of the steel tower 70, the slides 30 of the main hanging basket 10 and the tail hanging basket 20 can surround the steel tower 70 to form a stable support. Furthermore, through the guardrails 40 installed on the main hanging basket 10 and the tail hanging basket 20 respectively, the main hanging basket 10, the tail hanging basket 20, and the guardrails 40 form a U-shaped corridor, allowing workers to safely perform construction within this corridor. When the cross-section of the steel tower 70 changes, the slides 30 are first moved away from the main hanging basket 10. After the main hanging basket 10 is raised to the corresponding height using a crane, it is fixed to the steel tower 70. Then, the slides 30 slide towards the main hanging basket 10, with the main hanging basket 10 and the slides 30 surrounding the steel tower 70. This effectively improves the adaptability of the steel tower circumferential joint construction platform to variable cross-section steel towers 70.

[0031] It should be emphasized that the main hanging basket 10 and the tail hanging basket 20 brackets can be connected by bolts, which facilitates assembly and disassembly.

[0032] Please refer to Figure 5 In one embodiment of this application, a tie rod 60 is provided between the main hanging basket 10 and the steel tower 70. Main hanging ears 12 are distributed on the inner side of the main hanging basket 10, and auxiliary hanging ears 71 are provided on the steel tower 70 at the corresponding positions of the main hanging ears 12. One end of the tie rod 60 is connected to the main hanging ear 12, and the other end of the tie rod 60 is connected to the auxiliary hanging ear 71.

[0033] In this application, the main hanging ear 12 of the main hanging basket 10 and the auxiliary hanging ear 71 of the steel tower 70 are fixed by a tie rod 60. The tie rod 60 is connected to the main hanging ear 12 and the auxiliary hanging ear 71 respectively by a cotter pin. The tie rod 60 is firmly connected and easy to disassemble, which improves the convenience of moving the main hanging basket 10.

[0034] In one embodiment of this application, the angle between the pull rod 60 and the horizontal plane is 60-70°.

[0035] When the angle between the tie rod 60 and the horizontal plane is 60-70°, the tie rod 60 is subjected to uniform force, the tie rod 60 exerts sufficient tension on the main hanging basket 10, and the stability between the steel tower 70 and the main hanging basket 10 is strong, effectively ensuring the construction safety of the workers.

[0036] In one embodiment of this application, a plurality of pulleys 11 are provided on the inner side of the main hanging basket 10, and the pulleys 11 are used to slide up and down the steel tower 70 when the main hanging basket 10 is hoisted.

[0037] In this application, when the main hanging basket 10 is moved relative to the steel tower 70, it is lifted by a crane. The main hanging basket 10 and the steel tower 70 are subjected to rolling friction through pulleys 11, which reduces the wear of the main hanging basket 10 on the steel tower 70 and improves the moving efficiency of the main hanging basket 10.

[0038] In one embodiment of this application, the pulley 11 is an industrial pulley 11 with a diameter of 130-160mm, a thickness of 60-70mm, and a load capacity of 50-60kg.

[0039] In this application, the pulley 11 has a diameter of 130-160mm, a thickness of 60-70mm, and a load capacity of 50-60kg. The specifications of the pulley 11 determine its load-bearing capacity, and the large contact surface between the pulley 11 and the steel tower 70 effectively reduces damage to the steel tower 70 when the main hanging basket 10 moves.

[0040] Please refer to Figure 3 In one embodiment of this application, the main hanging basket 10 includes a first hanging basket layer 101 and a second hanging basket layer 102, a connecting member is provided between the first hanging basket layer 101 and the second hanging basket layer 102, and a pulley 11 is provided on the inner side of the first hanging basket layer 101 and the second hanging basket layer 102.

[0041] In this application, the first hanging basket layer 101 and the second hanging basket layer 102 are connected and fixed by connectors, which can be steel bars, steel pipes, or angle iron. The first hanging basket layer 101 and the second hanging basket layer 102 have a certain height, ensuring sufficient contact area between the main hanging basket 10 and the steel tower 70, making it easier for the main hanging basket 10 to maintain stability after fixation. Furthermore, the layered, perforated structure effectively reduces the weight of the main hanging basket 10 itself, lowering the pressure exerted by the main hanging basket 10 on the steel tower 70.

[0042] In one embodiment of this application, the first hanging basket layer is located above the second hanging basket layer 102 in terms of horizontal height, and the first hanging basket layer 101 extends outward from the second hanging basket layer 102. The first hanging basket layer 101 is used to support workers to operate on the steel tower 70.

[0043] In this application, the spatial positions of the first hanging basket layer 101 and the second hanging basket layer 102 are staggered. While ensuring the safety of construction workers, the materials of the second hanging basket layer 102 are saved, the cost is reduced, and the overall weight of the main hanging basket 10 is reduced, thus reducing the pressure of the main hanging basket 10 on the steel tower 70.

[0044] In one embodiment of this application, the angle between the plane where the main hanging basket 10 is located and the plane where the tail hanging basket 20 is located is 20-30°.

[0045] In this application, due to the structural influence of the teardrop-shaped steel tower 70 itself, after the main hanging basket 10 is fixed to the steel tower 70, the main hanging basket 10 is not placed horizontally. The angle between the plane where the main hanging basket 10 is located and the plane where the tail hanging basket 20 is located is 20-30°. The tail hanging basket 20 is basically parallel to the horizontal plane, which facilitates the construction convenience of the staff on the tail hanging basket 20.

[0046] In one embodiment of this application, an anti-slip layer 50 is provided on the upper surface of the first hanging basket layer 101.

[0047] In this application, due to the structural influence of the teardrop-shaped steel tower 70 itself, after the main hanging basket 10 is fixed to the steel tower 70, the main hanging basket 10 is not placed horizontally, that is, the first hanging basket layer 101 has a certain angle with the horizontal plane. The anti-slip layer 50 can improve the stability of the workers when standing on the first hanging basket layer 101 and improve the safety of the workers during construction.

[0048] In one embodiment of this application, the anti-slip layer 50 includes a plurality of angle irons, which are evenly distributed on the first hanging basket layer 101.

[0049] In this application, the angle irons are staggered and irregular, which can play a good anti-slip role, and the angle irons can also play a reinforcing role, providing stability to the first hanging basket layer 101.

[0050] Please refer to Figure 4This application has been applied to the construction of the teardrop-shaped steel-concrete composite tower of the Ziyun Bridge, which has effectively improved the construction efficiency of the teardrop-shaped steel-concrete composite tower and ensured the safety of construction personnel.

[0051] In the technical solution of this application embodiment, the main hanging basket 10 is lifted to a suitable position on the steel tower 70 by a crane, and the main hanging basket is fixed to the steel tower 70. The cross-section of the steel tower 70 changes direction and slides to the main hanging basket 10 via the slide 30 of the tail hanging basket 20. The main hanging basket 10 and the slide 30 surround the steel tower 70, forming a stable support for the workers. This can be applied to situations where the cross-section of the steel tower 70 changes continuously in a certain direction, improving the installation adaptability of the main hanging basket 10. At the same time, guardrails 40 are set on the inner and outer sides of the main hanging basket 10 and the tail hanging basket 20. The main hanging basket 10, the tail hanging basket 20 and the guardrails 40 form a U-shaped corridor for workers to walk through, effectively ensuring the operational safety of the workers.

[0052] It should be understood that this application is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
