Description

Technical Field

[0001] The utility model relates to the technical field of concrete wind power towers, and specifically relates to a tapered temporary working platform. Background Technique

[0002] With the continuous growth of the global demand for clean energy, wind energy, as a renewable and pollution-free energy source, has become increasingly important in the energy field. Wind power generation technology has been widely applied and developed, and the construction scale of wind farms has been continuously expanding. Concrete wind power towers are important supporting structures for wind turbines, and their quality and construction efficiency directly affect the whole. In the construction of wind power towers, concrete towers have gradually become an important choice due to their advantages such as stable structure, good durability, and relatively low cost. Compared with traditional steel structure towers, concrete towers can better adapt to complex geographical and climatic conditions, especially in some areas with strong winds and high cold.

[0003] Traditional working platforms are usually of fixed or simple hanging structures and are difficult to adapt to concrete wind power towers with different diameters and heights. During the construction process, since the diameter of the tower may change with the height, traditional working platforms cannot be adjusted flexibly, which limits the construction efficiency and quality. Content of the Utility Model

The first support platform and the second support platform are provided, and they can be flexibly adjusted according to the actual size of the tower barrel. Whether in the area where the diameter of the tower barrel gradually increases or decreases, the extension length of the support platform can be adjusted to closely fit the inner wall of the tower barrel, ensuring the stability and safety of the working platform.

[0008] Preferably, threaded push blocks are fixedly installed on the outer walls of the bottoms of the first support platform and the second support platform. Threaded holes are provided in the threaded push blocks. A guiding and fixing block is fixedly installed inside the slide rail.

[0014] (1). Through the cooperation among the fixed slide bar, the sliding slot, the rectangular clamping slot, the support platform one, the support platform two, the slide rail, the guiding slide bar and the motor, the utility model can extend outwards according to the construction needs, increasing the activity space of the operators. When carrying out the construction operation of the concrete wind power tower barrel, the construction workers can carry out operations such as material handling and tool placement on a wider platform, avoiding the problems of inconvenient operation and low efficiency caused by the narrow operation space. As the construction height of the concrete wind power tower barrel increases continuously, the diameter of the tower barrel may change. The platform extension part can be adjusted accordingly according to the tower barrels with different diameters, ensuring that the working platform can always closely fit the inner wall of the tower barrel.

[0015] (2). Through the cooperation among the installation block, the threaded lead screw, the hand wheel, the fixing plate, the steel frame installation slot, the rotating hand block, the rotating block, the clamping block, the connecting block and the hoisting block two, when the construction workers are operating, if the working platform moves accidentally, it will cause the construction workers to lose their balance and increase the risk of falling. The platform can be firmly fixed on the steel frame inside the tower barrel, so that it will not move even when subjected to external forces, providing a stable working plane for the construction workers. When the working platform bears a large construction load, it can ensure that the connection between the platform and the tower barrel steel frame is firm and reliable, evenly transmitting the load to the tower barrel steel frame, and avoiding structural damage or instability caused by the platform shaking or excessive local stress.

[0026] A chute 312 is provided on the fixed sliding rod 311, and rectangular clamping grooves 313 are equidistantly provided inside the chute 312. Sliding grooves are provided on both the first support platform 314 and the second support platform 315. The first support platform 314 and the second support platform 315 are slidably connected to the fixed sliding rod 311 through the sliding grooves, and support fixing grooves 316 are provided on the outer walls of both the first support platform 314 and the second support platform 315.

[0027] Threaded push blocks 3117 are fixedly installed on the outer bottom walls of both the first support platform 314 and the second support platform 315. Threaded holes are provided in the threaded push blocks 3117. A guiding fixed block 318 is fixedly installed inside the slide rail 317. Guiding sliding rods 319 are fixedly installed on both outer walls of the guiding fixed block 318. A support sliding plate 3111 is slidably connected inside the slide rail 317.

[0032] The internal thread of the threaded rotation hole is connected with the threaded screw rod 412. One end of the threaded screw rod 412 extends into the internal of the steel frame mounting clamping groove 415 through the threaded rotation hole. One end of the threaded screw rod 412 is rotatably connected with a fixing plate 414. The other end of the threaded screw rod 412 is fixedly installed with a hand wheel 413.

[0033] During the process of this embodiment, a crane is used to lift the working platform into the interior of the tower barrel through the first lifting block 2 and the second lifting block 5, and then the working platform is snap-fitted and installed on the steel frame of the tower barrel through the mounting block 411. Then, by manually rotating the handwheel 413, the fixing plate 414 is driven by the threaded lead screw 412 to fixedly install the working platform on the steel frame of the tower barrel. When construction workers are working, if the working platform moves accidentally, it will cause the construction workers to lose their balance and increase the risk of falling. The platform can be firmly fixed on the steel frame inside the tower barrel so that it will not move even when subjected to external forces, providing a stable working plane for the construction workers. When the working platform bears a large construction load, it can ensure that the connection between the platform and the steel frame of the tower barrel is firm and reliable, evenly transferring the load to the steel frame of the tower barrel to avoid structural damage or instability caused by platform shaking or excessive local stress.

[0034] Working principle: First, a crane is used to lift the working platform into the interior of the tower barrel through the first lifting block 2 and the second lifting block 5, and then the working platform is snap-fitted and installed on the steel frame of the tower barrel through the mounting block 411. Then, by manually rotating the handwheel 413, the fixing plate 414 is driven by the threaded lead screw 412 to fixedly install the working platform on the steel frame of the tower barrel. Then, by manually rotating the rotating hand block 416, the clamping block 418 is driven to rotate 90 degrees inside the rectangular clamping groove 313, so that the clamping block 418 slides in the sliding groove 312. Then, the motor 3115 is started to drive the threaded rod 3116 to rotate. When the threaded rod 3116 rotates, the support platform one 314 and the support platform two 315 are respectively driven by the threaded push block 3117 to move outward. During the outward movement of the support platform one 314 and the support platform two 315, the support sliding plate 3111 is driven by the fixed clamping block 3112 to slide in the slide rail 317, so that the support platform one 314 and the support platform two 315 slowly extend outward through the guiding and positioning of the fixed slide rod 311. When moving to the appropriate position, by manually rotating the rotating hand block 416 to drive the clamping block 418 to rotate 90 degrees, the clamping block 418 is engaged with the rectangular clamping groove 313, so that the support platform one 314 and the support platform two 315 are fixed at the current position to ensure that there is no displacement during work.
