[0028] like Figure 6 , Figure 7 , Figure 8 As shown, the support mechanism 2 includes a positioning tube 21, a movable part 22, and a fine-tuning assembly. The positioning tube 21 is fixedly connected to the bottom end of the end angle position of the fixed pedal 1. The axial direction of the positioning tube 21 is consistent with the diagonal length of the fixed pedal 1. One end of the positioning tube 21 extends from the inner side of the fixed pedal 1 and a positioning through hole 211 is provided on the top of the end.

A plurality of positioning grooves 221 are provided at equal intervals on the top of the movable part 22 along the length direction of the movable part 22. The positioning through hole 211 can be connected with a positioning pin 27 between any positioning groove 221; support protrusions 222 are integrally formed on the side walls on both sides of the movable part 22, and the length direction of the support protrusion 222 is consistent with the length direction of the movable part 22. A guide through groove 212 for avoiding the support protrusion 222 is provided on the inner wall of the positioning tube 21; when the movable part 22 is sleeved in the positioning tube 21, the support protrusion 222 is located in the guide through groove 212 and can slide along the guide through groove 212; the fine-tuning component is arranged at one end of the movable part 22 close to the avoidance notch 8.

[0029] When construction is required on an area with a smaller outer diameter at the upper end of the power tower, the platform frame is hoisted as a whole to the upper end of the power tower by means of hoisting equipment, and then the movable parts are moved toward the multiple supporting columns of the power tower, so that the fine-tuning components are brought close to the supporting columns of the power tower and squeezed, and then the positioning through holes and the positioning grooves are connected by positioning pins; finally, the fine-tuning components are adjusted to clamp the supporting columns of the power tower to achieve a stable connection between the platform frame and the power tower; in order to ensure a balanced supporting effect of the four supporting mechanisms, digital marks can be set on each positioning groove to keep the extended lengths of the movable parts in the four supporting mechanisms consistent.

[0031] The outer side of the fine-tuning screw 23 is sleeved with a screw nut 26, which is threadedly connected to the outer wall of the fine-tuning screw 23; when the fine-tuning screw 23 is adjusted, the screw nut 26 is rotated to make one end side wall of the screw nut 26 abut against one end wall of the movable part 22.

[0032] After the movable part is adjusted, the fine-tuning screw is rotated to move the fine-tuning screw toward the support column of the power tower until the extrusion part abuts against the support column, and the screw nut is rotated to abut against the end face of the movable part to achieve the positioning of the fine-tuning screw and avoid the fine-tuning screw from rotating and loosening during the construction process; the design of the pin connection between the extrusion part and the rotating part allows the extrusion part to swing up and down. For the inclined support column, the extrusion part can be tilted at a certain angle accordingly, so that the extrusion part is completely in contact with the outer wall of the support column, thereby improving the stability of the connection structure between the extrusion part and the support column after extrusion.

[0033] like Figure 4 , Figure 5 , Figure 6 As shown, the movable pedal 7 is arranged in an isosceles trapezoidal shape, and a side of the movable pedal close to the power generation tower is provided with an avoidance groove for avoiding the power generation tower, and both sides of the oblique side of the movable pedal 7 are respectively placed on the support protrusions 222 of two groups of adjacent support mechanisms 2.

[0035] After the supporting mechanism is extended and clamped on the supporting column of the power tower, the movable pedal is placed on the supporting protrusion on one side of the movable part and then fixed with bolts; the movable pedal can be designed into multiple types according to the range of variation of the outer diameter of the power tower, and its width can also be designed according to the use requirements. Its shape can also be designed into other shapes according to the power tower with different supporting column structures to improve the construction convenience; in order to facilitate the carrying of the movable pedal, a mounting frame can be set on the fixed pedal to place the movable pedal. Of course, lifting equipment can also be used for lifting operations when the movable pedal is needed.

[0036] The decentralized micro-wind power generation conical steel frame construction operation special platform also includes a lifting mechanism; the lifting mechanism includes a lifting frame 4, a lifting device 6, and a lifting rope 5; there are four lifting frames 4, and the four lifting frames 4 are evenly distributed at the top of the power generation tower 3, one end of the lifting frame 4 is fixedly connected to the power generation tower 3 through a fixing member, and the other end of the lifting frame 4 is tilted upward and the end of the end is rotatably connected to a guide wheel 401; the fixed pedal 1 is surrounded by a lifting ring 101 corresponding to the lifting frame 4, one end of the lifting rope 5 is connected to the lifting ring 101, and the other end of the lifting rope 5 passes through the guide wheel 401 on the corresponding lifting frame 4 and is wound around the lifting device 6; the lifting device 6 is fixedly connected to the ground at the center of the bottom end of the power generation tower 3.

[0037] When carrying out construction operations, the platform frame can be directly hoisted by crane equipment; the above-mentioned lifting mechanism can also be used for operation. When using the lifting mechanism, it is necessary to first install four lifting frames on the top of the power generation tower through fixing parts, and then install the two ends of the lifting rope on the lifting ring and the lifting device. Under the action of the guide wheel on the lifting frame, the platform frame can be raised and lowered by controlling the lifting device. It does not need to frequently use crane equipment for power generation tower construction operations, making the construction operation of the power generation tower more convenient.

[0038] The fixed pedal and movable pedal structures in the utility model can be designed into various specifications, and can be freely assembled and used in combination according to the height and outer diameter of the power generation tower, so that it can be applicable to the construction operation of power generation towers with various structures, and has a wide range of uses.

[0039] The utility model adopts a design in which a platform frame is composed of a fixed pedal, a movable pedal, and a supporting mechanism. When performing construction operations on an area with a larger outer diameter at the bottom end of a power generation tower, the fixed pedal is directly hoisted to the outer periphery of the bottom end of the power generation tower, and the supporting mechanism is used to abut against multiple supporting columns on the outer periphery of the power generation tower to ensure the installation stability of the fixed pedal. At this time, the construction personnel can stand on the fixed pedal to perform construction operations on the power generation tower, such as Figure 1 , Figure 2 As shown; when construction operations are performed on the area with a smaller outer diameter at the upper end of the power generation tower, the fixed pedal is hoisted to the outer periphery of the upper end of the power generation tower, and a plurality of support columns at the outer periphery of the power generation tower are abutted by the support mechanism, and then the movable pedal is installed on the adjacent support mechanism on the inner side of the fixed pedal; at this time, the enclosed area of ​​the entire platform frame becomes smaller and matches the outer diameter of the power generation tower, and the construction workers can stand on the movable pedal to perform construction operations on the power generation tower, as shown in FIG. Figure 3 , Figure 4 , Figure 5 As shown; the entire device has a simple structure and is easy to use. It only needs one platform frame structure to realize standing construction operations in different outer diameter areas of the power tower. There is no need to lift and replace construction platforms in multiple different enclosed areas to meet the construction needs of different outer diameter areas of the power tower. The entire construction process does not require frequent lifting operations, which saves time and effort while improving the installation and construction efficiency of the power tower, bringing convenience to the construction of the power tower.
