DETAILED DESCRIPTION

[0022] like Figures 1 to 8As shown, the present invention proposes a top construction platform of a tower crane for tower construction, comprising a construction platform body 1 mounted on a column, a column lifting passage 11 for the column to pass through is provided on the construction platform body 1, and six column lifting passages 11 are provided in a circular array, an extension platform body 2 is provided on the upper surface of the construction platform body 1, the extension platform body 2 extends toward the middle of the construction platform body 1, and a plurality of construction openings for construction are provided in the extension platform body 2; The extension platform body 2 includes three platform monomers arranged in an array, each two adjacent platform monomers are abutted against each other, and the three platform monomers are arranged in a staggered manner, each platform monomer includes a symmetrically arranged plate-rail dual-purpose body 21 and an extension boss 22, and each of the two plate-rail dual-purpose bodies 21 is provided with an extension boss 22, and the two extension bosses 22 extend toward the middle of the construction platform body 1, and the two extension bosses 22 abut against each other, and the construction opening is formed between the left and right adjacent extension bosses 22 and the plate-rail dual-purpose body 21; The plate-rail dual-purpose body 21 includes a fixed plate 211 and a movable railing 212. The movable railing 212 is arranged near the middle of the construction platform body 1. The fixed plate 211 is connected to the movable railing 212 through a swing connecting shaft 215 arranged at its upper end to adjust the size of the construction opening by bending and swinging the movable railing 212.

[0023] The top construction platform of the tower-building crane proposed in the present invention effectively solves the many problems of existing construction platforms mentioned in the background technology when constructing a curved tower body through its unique function of adjusting the size of the construction opening. The traditional construction platform has a fixed area and cannot be flexibly adjusted according to the curvature of the tower body, which makes it difficult for construction workers to approach the casting point and requires frequent construction and dismantling of the platform, increasing the difficulty and cost of construction. The construction platform of the present invention can flexibly adjust the size of the construction opening through the bending and swinging of the movable railing 212 of the dual-purpose plate and railing body 21, so that construction workers can more conveniently approach the casting point of the tower body without the need to build an additional platform, which greatly improves the flexibility and efficiency of construction and reduces construction costs and labor intensity. The top construction platform of the present invention is installed on a column, and the column passes through the construction platform body 1 through a column lifting channel 11. An extension platform body 2 is provided on the construction platform body 1, which is composed of three platform monomers arranged in an array, and adjacent platform monomers are abutted and staggered. Each platform monomer includes a symmetrically arranged plate and fence dual-purpose body 21 and an extension boss 22, and the extension boss 22 extends toward the middle of the construction platform body 1 and abuts against each other to form a construction opening. When the size of the construction opening needs to be adjusted to adapt to the change in the curvature of the tower body, the movable guardrail 212 is arranged near the middle of the construction platform body 1, and the swing connection shaft 215 at the upper end of the fixed plate 211 is connected to the movable guardrail 212 to achieve the bending and swinging of the movable guardrail 212. The operator can adjust the angle of the movable guardrail 212 manually or through the control system according to the curvature of the tower body and the construction requirements, thereby changing the size of the construction opening, so that the construction personnel can more accurately approach the pouring point of the tower body for construction.

[0024] The extension platform body 2 is installed on the upper surface of the construction platform body 1 and extends toward the middle of the construction platform body 1 to expand the construction area. The extension platform body 2 is composed of three platform units arranged in an array, with each two adjacent platform units abutting against each other, and the three platform units are arranged in an interlaced manner. This design enables the construction platform to be flexibly adjusted in different directions to adapt to the curvature changes of the tower body.

[0025] A preferred technical solution is that the left and right sides of the board-rail dual-purpose body 21 are both arranged as inclined surfaces, and two adjacent board-rail dual-purpose bodies 21 are abutted against each other through the inclined surfaces arranged on their respective sides, and the upper surface of the board-rail dual-purpose body 21 is provided with a plurality of inwardly recessed strip grooves 102, and the strip grooves 102 on the symmetrically arranged board-rail dual-purpose body 21 correspond to each other, and the extension boss 22 is provided with a convex strip 225 corresponding to the strip groove 102, and when the extension boss 22 is installed to the surface of the board-rail dual-purpose body 21, the convex strip 225 is embedded in the strip groove 102, and the two opposite extension bosses 22 abut against each other.

[0026] The left and right sides of the plate and rail dual-purpose body 21 are designed as inclined surfaces, and two adjacent plate and rail dual-purpose bodies 21 are abutted by the inclined surfaces of their respective sides. This inclined surface design allows the adjacent plate and rail dual-purpose bodies 21 to fit tightly together to form an integral structure, while providing stable support for the construction platform. The design of the inclined surface also allows the shape of the tower body to be better adapted by adjusting the relative position of the plate and rail dual-purpose body 21 when the curvature of the tower body changes, thereby reducing the construction inconvenience caused by the fixed platform. Before construction, according to the design shape of the tower body and construction requirements, the plate and rail dual-purpose body 21 is assembled into a whole by abutting the inclined surfaces. At this time, the extended boss 22 is engaged with the strip groove 2102 on the plate and rail dual-purpose body 21 through the convex strip 225 to form a stable construction platform. When the curvature of the tower body changes, the construction personnel can change the fitting angle of the inclined surface by adjusting the relative position of the plate and rail dual-purpose body 21, thereby adapting to the shape change of the tower body. At the same time, the interlocking design between the convex strip 225 of the extended boss 22 and the second strip groove 102 ensures the stability of the platform during the adjustment process.

[0027] Furthermore, during the construction process, the construction personnel can flexibly adjust the shape and size of the construction platform by adjusting the slope angle of the plate-rail dual-purpose body 21 and the position of the extended boss 22, so that it can better adapt to the curvature change of the tower body. Due to the embedded design of the strip groove 202 and the convex strip 225, the construction platform always remains stable during the adjustment process, reducing the safety hazards caused by the shaking or instability of the platform.

[0028] A preferred technical solution, the end of the extension boss 22 away from the middle of the construction platform body 1 is in a C-shaped structure, and the extension boss 22 is fixed to the plate and fence dual-purpose body 21 through the C-shaped structure at its end. The C-shaped structure at the end of the extension boss 22 is designed to enable it to be firmly fixed to the plate and fence dual-purpose body 21; this design not only provides mechanical fixation, but also reduces the risk of loosening caused by vibration or external force through shape matching. Compared with traditional bolt connection or welding, the fixing method of the C-shaped structure is more flexible and easy to adjust. The end of the extension boss 22 close to the middle of the construction platform body 1 is provided with a connecting portion 221, and the two opposite extension bosses 22 are offset by the connecting portions 221 set at their respective ends; the C-shaped structure design of the second magnetic block 224 enables it to be adsorbed with the magnetic block on the adjacent extension boss 22. This magnetic connection not only enhances the stability between the two extension bosses 22, but also further fixes the overall structure of the platform through the action of magnetic force. The advantage of magnetic connection is that it can automatically align and maintain connection, and even if there is a slight displacement during the construction process, the magnetic force can quickly restore the stability of the connection.

[0029] A first magnetic block 223 and a second magnetic block 224 are disposed at both ends of the extension boss 22. When the two extension bosses 22 are facing each other and close to each other, the two extension bosses 22 are adsorbed by the adjacent second magnetic block 224, and the second magnetic block 224 is in a C-shaped structure.

[0030] A preferred technical solution is that the plate-rail dual-purpose body 21 is fixed to the surface of the construction platform body 1 by a supporting fixed plate 213 arranged at its lower end, and there is a spacing between the plate-rail dual-purpose body 21 and the construction platform body 1, and a strip groove 101 extending to the ends of the fixed plate 211 and the movable railing 212 on both sides is provided on the lower side of the plate-rail dual-purpose body 21, and a cylinder 214 is provided in the strip groove 101, and the end of the cylinder 214 is movably connected to the fixed plate 211, and the output shaft of the cylinder 214 is movably connected to the movable railing 212, so that the bending angle of the movable railing 212 can be adjusted by driving the output shaft of the cylinder 214 to extend and retract.

[0031] A preferred technical solution, the end of the cylinder 214 away from the output shaft is installed on the side of the strip groove 101 close to the fixed plate 211 through a bearing seat, and the output shaft of the cylinder 214 is connected to the side of the strip groove 101 close to the movable baffle 212 through a curved seat, the curved seat is bent toward the fixed plate 211, and protrudes from the lower surface of the movable baffle 212, the bending angle of the curved seat is 45°, so that when the output shaft of the cylinder 214 pushes the curved seat, the movable baffle 212 swings upward 45° to form a guardrail, the movable baffle 212 is driven by the cylinder 214, and can be quickly and accurately adjusted to the 45° position to form a stable guardrail. Compared with the traditional fixed guardrail, this automated adjustment method is It can be quickly deployed according to construction needs, effectively preventing construction workers from falling accidents when working at heights. The output shaft of the cylinder 214 is connected to the movable guardrail 212 through a curved seat. This connection method not only ensures the stable swinging of the movable guardrail, but also ensures that the movable guardrail always remains balanced during the swinging process through the 45° bending angle design of the curved seat. The cylinder-driven movable guardrail 212 can quickly form a guardrail, reducing construction preparation time. Compared with the traditional guardrail installation method, the cylinder-driven guardrail system does not require complicated tools or equipment. Construction workers can complete the deployment of the guardrail through simple operations. This rapid deployment capability is particularly important in a changing construction environment and can significantly improve construction efficiency.

[0032] Furthermore, when the extension boss 22 is not installed and the two adjacent movable guardrails 212 are both swung upward by 45°, a V-shaped observation port is formed between the inclined surfaces of the two adjacent guardrail bodies 21. The design of the V-shaped observation port provides a wider field of vision for construction workers, allowing them to observe the construction of the tower body more clearly. This design is particularly suitable for scenes that require high-precision construction, such as observation of the pouring points or connection points of the tower body. The V-shaped structure between the inclined surfaces can reduce visual blind spots, ensuring that construction workers can observe the construction area in all directions, thereby improving construction quality.

[0033] The design of the V-shaped observation port fully utilizes the space between the plate and fence dual-purpose body 21, and no additional observation equipment or structure is required. This design not only saves space, but also reduces the complexity of the construction platform. Compared with the traditional observation port design, the V-shaped observation port can better adapt to the dynamic changes of the construction platform. Even when the movable fence 212 adjusts the angle, the shape and position of the observation port can remain stable.

[0034] Furthermore, the connecting parts 221 disposed on the adjacent surfaces of the two extending bosses 22 abut against each other to form a workbench load-bearing part. There are three workbench load-bearing parts, and the three workbench load-bearing parts are staggered with each other up and down.

[0035] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
