[0038] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0039] The embodiment of the utility model provides a fully enclosed wind shaft construction operation lifting platform, which uses a pre-buried casing and then inserts a support member (for example, a steel pipe) as a support system for the operating platform, and casings are pre-buried at different floor heights of the wind shaft (that is, pre-buried layer by layer), so that a support platform can be formed at different floor heights of the wind shaft. During specific construction, the operating platform can be lifted and lowered in the wind shaft with the help of a tower crane, so that the operating platform can be supported at any floor height of the wind shaft to perform corresponding construction operations.

[0040] Specifically, Figure 1 and Figure 2 As shown in the figure, a fully enclosed wind shaft construction operation lifting platform provided by the embodiment of the utility model includes a support platform 1 and an operation platform 2. The support platform 1 can be detachably installed at any floor height through a pre-buried casing 20 on the wind shaft 10, thereby providing a support foundation for the operation platform 2 at different floor heights of the wind shaft. Accordingly, a lifting lug 3 is provided on the operation platform 2 (refer to Figure 4 As shown), it is lifted and lowered in the wind shaft by hoisting, so as to be supported on the supporting platform 1 at different positions.

[0041] In the above embodiment, if Figure 1 and Figure 3 As shown, the support platform 1 includes a plurality of support members 11. Specifically, the support member 11 is a steel pipe (it can also be replaced by other pipe structures with sufficient strength). In addition, the plurality of support members 11 are movably arranged in the horizontal direction in the pre-buried casing 20 at any floor height position (for example: the 5th floor) of the wind shaft 10, so as to form a support platform 1 at the corresponding floor height (i.e.: the location of the 5th floor). Figure 3 As shown, in this embodiment, the air shaft 10 is a fully enclosed structure, a cylindrical space 110 is formed in the center of the air shaft 10, and a plurality of casings 20 are pre-buried on the inner wall of the cylindrical space 110 at each layer height along the height direction.

[0042] In addition, in order to improve the stability of the supporting platform 1. In the above embodiment, preferably, as Figure 2As shown, anti-skid fasteners 30 are installed at positions corresponding to each casing 20 on the air shaft. When the support member 11 is inserted into the casing 20, the anti-skid fasteners 30 are fastened to the support member 11 to limit the relative position of the support member 11 and the casing 20. Therefore, after fastening the anti-skid fasteners 30, relative movement between the support member 11 and the casing 20 can be avoided, thereby ensuring the stability of the support platform 1. When the support member 11 needs to be removed, the anti-skid fasteners 30 are opened, and the support member 11 can move freely in the casing 20. More preferably, anti-skid fasteners 30 are installed on the inner wall and outer wall corresponding to each casing 20 on the air shaft, thereby further improving the limiting effect.

[0043] like Figure 4 As shown, in the above embodiment, the operating platform 2 includes a platform bottom plate 21, a support portion 22 and a platform top plate 23. The platform bottom plate 21 is rectangular and supported on the supporting platform 1. The shape of the platform bottom plate 21 matches the shape of the cylindrical space 110, and the top of the platform bottom plate 21 forms the lifting ear 3. The support portion 22 is arranged on the top of the platform bottom plate 21 to provide support for the platform top plate 23. The platform top plate 23 is supported on the top of the support portion 22 to provide a construction operation space for operators.

[0044] like Figure 4 As shown, in the above embodiment, preferably, the platform bottom plate 21 includes a central fixed plate 211 and an outer movable plate 212, the central fixed plate 211 is supported on the support platform 1, and the outer movable plate 212 is movably installed around the central fixed plate 211 to adjust the size of the platform bottom plate 21. Specifically, there are four outer movable plates 212, and the four outer movable plates 212 are respectively installed around the central fixed plate 211 in a flippable manner around the horizontal direction. When the operating platform 2 needs to be lifted, the four outer movable plates 212 can be flipped 90°. At this time, the horizontal coverage area of ​​the platform bottom plate 21 is reduced, thereby ensuring that there is enough lifting space during lifting, which can improve the lifting efficiency on the one hand, and ensure the safety of lifting on the other hand, and reduce the risk of collision between the operating platform 2 and the wind shaft components. It can be understood that in this embodiment, setting the outer movable plate 212 in a flippable form is only a preferred embodiment. In another embodiment, the outer movable plate can also be installed telescopically around the central fixed plate in the horizontal direction to adjust the size of the platform bottom plate. The specific structural form is not limited here.

[0045] In addition, if Figure 1As shown, preferably, a limit stopper 213 is formed at the bottom of the platform bottom plate 21 and at the position corresponding to each support member 11. When the platform bottom plate 21 is supported on the support platform 1, each support member 11 is respectively clamped in the corresponding limit stopper 213, thereby limiting the relative position of the platform bottom plate 21 and the support platform 1 to prevent the platform bottom plate 21 from sliding on the support platform 1, further improving the overall stability. Preferably, the limit stopper 213 can be formed by two angle steels, and in other embodiments, it can also be set to other structural forms, which are not specifically limited here.

[0046] like Figure 4 As shown, in the above embodiment, preferably, the support portion 22 includes a plurality of support rods. The bottoms of the plurality of support rods are collectively arranged in a rectangular shape, and the rectangular shape arranged by the plurality of support rods is located in the same plane as the rectangular shape of the platform bottom plate 21 and is rotated and misaligned, so that the platform bottom plate 21 forms avoidance areas 210 at the four corners, and each avoidance area 210 is provided with a lifting lug 3. It can be understood that by installing the support portion 22 and the platform bottom plate 21 in a misaligned manner, four avoidance areas 210 for installing the lifting lugs 3 can be formed, so that the lifting cables are not affected by the platform, thereby improving the convenience of lifting. In addition, it should be understood that the plurality of support rods can also be arranged in other shapes, such as diamond, triangle, etc., as long as the lifting lugs 3 can be reasonably installed to facilitate the lifting of the operating platform 2.

[0047] In another embodiment, preferably, the height of the support portion 22 is adjustable to adjust the current construction height of the platform top plate 23. Therefore, during specific construction, after the operating platform 2 is positioned on the corresponding construction floor through the support platform 1, the support portion 22 can be used to perform a small range of height adjustment within the floor to meet different construction requirements.

[0048] On the basis of the above-mentioned embodiments, the embodiments of the utility model also provide a construction equipment, which includes the above-mentioned wind shaft construction operation lifting platform, and may also include a tower crane, a casting device, a control system, etc., so as to realize a complete set of construction processes.
