Description

Technical Field

[0001] The utility model relates to a sliced ​​tower platform and belongs to the technical field of wind turbine generators. Background Art

[0002] The tower platform refers to the working platform inside tall buildings such as ventilation towers and cooling towers, which is generally located inside the tower. Its main function is to provide convenient conditions for maintenance, cleaning, safety inspection and other work, and to prevent falling objects from above. The tower platform is usually set at a suitable position inside the tower. The main part is made up of multiple support beams, and steel plates of different shapes are set above the support beams according to the position of the support beams. The steel plates are connected by welding.

[0003] However, the diameter of the tower is getting bigger and bigger, which leads to the diameter of the platform inside the tower getting bigger and bigger. The tower is lying down whether in the tower factory or during transportation. Due to its own weight, the tower will undergo elastic deformation. The conventional platform uses a welded integral structure to be rigidly connected to the tower wall. The connecting parts welded between the platform and the tower wall are stressed, and the deformation resistance is limited, so the connecting parts will break. The larger the diameter of the cylinder, the more likely this will happen, and the broken position is below the platform, which is difficult to repair. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] A segmented tower platform, such as Figure 1 , Figure 2 As shown, it includes a platform bracket 1 for connecting to the tower, and the platform bracket 1 includes a plurality of bracket units 11; a platform support plate 2 is provided on the platform bracket 1, and the platform support plate 2 is composed of a plurality of support plate units 21 which are arranged in sequence along the circumference of the tower and are independent of each other, and at least one bracket unit 11 is provided under each support plate unit 21.

[0024] Specifically, the platform bracket 1 is used to support the platform support plate 2, transfer the platform support plate 2 and its load to the tower, transfer the load, and thus ensure the stability of the support; the platform support plate 2 is used to bear the upper load and provide a larger support area, so that the staff can carry out a wider range of activities. In addition, the platform is divided into several small platforms by a plurality of independent support plate units 21, and a bracket unit 11 is arranged under each petal platform, so that the platform becomes an independent individual piece by piece. The platform modules at the respective positions move independently, and will not cause the welding parts between the platform and the cylinder to be pulled apart like the previous integral platform. Furthermore, the bracket unit 11 is connected to the support plate unit 21 by bolts.

[0025] As another specific implementation, a weight-reducing hole 22 is provided in the middle of the platform support plate 2. Specifically, when working on the tower, people usually only move around the platform support plate 2, and the middle of the platform support plate 2 is not loaded. Therefore, providing a weight-reducing hole 22 in the middle of the platform support plate 2 can reduce the deadweight of the platform support plate 2, reduce the stress on the platform bracket 1 and the tower, and thus improve the reliability and service life of the platform bracket 1 and the tower. At the same time, it can also save materials and reduce manufacturing and transportation costs.

[0026] As another specific embodiment, a guardrail 23 is provided inside the support plate unit 21. Since a weight-reducing hole 22 is provided inside the support plate platform, the guardrail 23 can prevent workers from falling from the weight-reducing hole 22, thereby reducing safety hazards.

[0027] As another specific embodiment, the radial outer side of the support plate unit 21 is arc-shaped, the radial inner side of the support plate unit 21 is linear, and the outer peripheral line of the support plate unit 21 is symmetrical along the meridian of the tower. Specifically, the arc of the outer side of the support plate unit 21 is coaxial with the tower. By setting the outer side as an arc, the support plate unit 21 and the tower can be more closely fitted, reducing the risk caused by the gap, and ensuring that the gap between the support plate unit 21 and the tower is consistent, which is convenient for the assembly of the platform bracket 1. The linear inner side can facilitate the installation of the guardrail 23 and adapt to the guardrail 23.

[0028] As another specific embodiment, the platform support plate 2 is composed of a plurality of first support plate units 211, a second support plate unit 212 and a third support plate unit 213. The second support plate unit 212 is provided with a passage 2121 and a cable through hole 2122; the third support plate unit 213 is provided with a conductive rail through hole 2131. When the wind turbine generator set needs maintenance, the maintenance personnel need to go to the tower platform by elevator or ladder, and the passage 2121 can be used for the elevator or the staff to pass through. The cable through hole 2122 can be used for the cable to pass through during operation.

[0029] As another specific implementation, a cover plate 24 is provided on the passage 2121. The cover plate 24 can prevent the occurrence of a hollow space that poses a safety threat. Specifically, the cover plate 24 is hingedly provided on the passage 2121, and a support plate perpendicular to the cover plate 24 is provided on the side of the cover plate 24, and the support plate is used to support and limit the position.

[0030] As another specific embodiment, at least two bracket units 11 are respectively arranged below each support plate unit 21, wherein the two bracket units 11 are respectively arranged on both sides of the circumference of the support plate unit 21. By arranging the bracket units 11 on both sides of the support plate unit 21, the stability and balance of the support plate unit 21 can be improved, and the tilting, shaking and other problems caused by the imbalance of the center of gravity can be effectively avoided. Furthermore, for the sake of stability, if space permits, the bracket unit 11 can also be arranged in the middle of the support plate unit 21.

[0031] As another specific embodiment, the support unit 11 includes a support beam 111 arranged in a radial direction, and a reinforcing bar 112 is connected to the lower part of the support beam 111, and the lower end of the reinforcing bar 112 is arranged obliquely outward. Specifically, the end of the support beam 111 is connected to the tower, and the upper end surface of the support beam 111 is in contact with the support plate unit 21, thereby supporting the support plate unit 21. The upper end of the reinforcing bar 112 is connected to the support beam 111, and the lower end of the reinforcing bar 112 is connected to the tower, thereby effectively dispersing the load and stress and improving the strength of the support unit 11.

[0032] As another specific implementation, the outer ends of the support beam 111 and the reinforcement bar 112 are both provided with a connecting piece 113 for connecting with the tower. Specifically, the connecting piece 113 is welded with the tower.

[0033] As another specific implementation, a support bar 25 is provided on the lower plane of each support plate unit 21. Specifically, the bracket unit 11 is arranged along the radial direction of the tower, so that the circumferential force of the support plate unit 21 is ensured by the support bar 25. Specifically, the support bar 25 is arranged perpendicular to the circumferential symmetry line of the support plate unit 21.
