Description

Technical Field

[0001] This utility model relates to the field of cable crane tower technology, and in particular to a working platform for cable crane tower construction. Background Technology

[0002] Cable-stayed crane towers are a key component of cable-stayed hoisting systems, primarily used to support the cable system and provide stable support and a working platform for the hoisting of precast components. The columns are the main load-bearing components of the tower, used to withstand the tension from the cables and the weight of the hoisted components. They are interconnected through node connectors to form the vertical support structure of the tower. Column cross braces are the horizontal and diagonal members connecting the columns, used to enhance the overall stability and torsional stiffness of the tower, ensuring the tower maintains structural integrity under horizontal and vertical forces and preventing damage between the columns. In cases of relative displacement or deformation, existing technologies employ a climbing device to assemble the cable-stayed tower. This climbing device, resembling an elevator, is located inside the column. Due to its small internal structure, a crane is used to lift the tower column cross bracing, and workers manually align it before connecting it to the column. This method makes the tower column cross bracing prone to swaying during transport, and if it collides with the climbing device, it poses a significant safety hazard. Furthermore, when installing cross bracing at different locations, the crane needs to be constantly adjusted, increasing construction time. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Example

[0023] like Figures 1-4 As shown, a working platform for cable-stayed crane tower construction is provided. The cable-stayed crane tower includes several columns 1 and column cross bracing 2. The column cross bracing 2 is detachably installed between the columns 1. The working platform A includes several working plates, a ladder 62, fasteners, and a connecting plate 32 connecting the working plates. The working plates include working plate I3, working plate II4, and working plate III5, which are arranged parallel to each other. The connecting plate 32 connects working plate I3, working plate II4, and working plate III5 into one unit. The working plates are hollow and annular in shape, and the cross-section of the working plates is L-shaped. Several lifting lugs 31 are provided on the working plates for lifting. The crane is connected to the lifting lugs 31 to lift the working platform A and insert it from the top of the columns 1, so that the working platform A is detachably connected around the cable-stayed crane tower. Workers assemble the cable-stayed crane tower on the working plates.

[0024] like Figures 1-4 As shown, an opening 6 is provided on the work board, and a ladder 62 is provided between work boards I3, II4, and III5. The openings 6 on the different work boards are aligned with each other. The ladder 62 is placed inside the opening 6. Workers enter work board III5 and move to work board II4 and work board I3 via the ladder 62. A baffle 61 is provided at the opening 6. The baffle 61 is hinged to the work board and is located at the opening 6. The baffle 61 can close the opening 6 and rotates upwards on the work board. When a worker climbs into work board II4 or work board III5, the baffle 61 closes to prevent the worker from stepping on the opening 6 while working on the work board, thus avoiding a safety accident.

[0025] like Figures 1-5As shown, the fixing component is installed on the connecting plate 32 between the working plate I3 and the working plate II4. The fixing component includes a support plate 33 and a snap-fit ​​assembly. The fixing component is aligned with the tower column cross link 2. The support plate 33 is connected to the connecting plate 32. The snap-fit ​​assembly passes through the support plate 33 and is connected to the tower column cross link 2. The tower column cross link 2 is aligned with the support plate 33. The support plate 33 is provided with several slots 331, which are aligned with the upper and lower sides of the tower column cross link 2. The snap-fit ​​assembly includes a snap-fit ​​plate 34 and several protruding rods 341 provided on one side of the snap-fit ​​plate 34. The protruding rods 341 are inserted into the slots 331 and are attached to the upper and lower ends of the tower column cross link 2, fixing the working platform A to the tower column cross link 2. The snap-fit ​​plate 34 is attached to the support plate 33. The snap-fit ​​plate 34 and the support plate 33 are connected by bolts to prevent the snap-fit ​​assembly from sliding during the support process, further increasing the connection stability of the working platform A.

[0026] Working principle: First, insert columns 1 at designated locations, arranging several columns 1 in a ring. Connect the tower column cross bracing 2 starting from the lower end of the columns 1. A crane, using lifting lugs 31, transports the work platform A to the outside of the columns 1, aligning the support plate 33 with the uppermost tower column cross bracing 2. Insert the snap-fit ​​assembly into the slot 331, ensuring the protruding rod 341 fits against the tower column cross bracing 2. Workers then use the snap-fit ​​assembly within the work plate II 4 to fix the work platform A to the tower column cross bracing 2. Since the support plate 33 is positioned between work plates I 3 and II 4, once the work platform A is connected, the worker... Workers climb onto the work platform I3 using ladder 62 to connect new tower column crossbars 2 to the uprights 1. Once the tower column crossbars 2 at the work platform I3 are assembled, a crane lifts the work platform A, separates the snap-fit ​​components and support plate 33, and lifts the work platform A to align the support plate 33 with the newly constructed tower column crossbars 2. This process is repeated to continuously build new tower column crossbars 2 between the uprights 1. Compared to existing technologies, the tower column crossbars 2 can be placed on the work platform, making it easier for workers to align them during connection and eliminating concerns about collisions, thus greatly increasing safety during construction.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
