[0020] In related technologies, the steel bridge installation field has long used hanging basket platforms with triangular or rhomboid truss structures, relying on welded or bolted steel sections to construct the load-bearing system. These structures suffer from excessive weight and low mobility, requiring temporary scaffolding during river or road crossings, leading to increased material consumption and traffic disruption. Existing hanging basket platforms lack modularity, making them unsuitable for variable-span construction needs, and their low component reuse rate restricts construction efficiency.

[0021] To address the problems existing in the aforementioned related technologies, this embodiment provides a sliding hanging basket device.

[0022] like Figure 1-4As shown in the figure, the sliding hanging basket device provided by this utility model embodiment includes an upper platform 1, a lower platform 3, and a vertical support 2; the upper platform 1 and the lower platform 3 are respectively connected to the upper and lower ends of the same side of the vertical support 2; the upper platform 1 includes a main beam 13 and an upper horizontal support 11; two upper horizontal supports 11 are arranged at intervals; one end of the upper horizontal support 11 is connected to the vertical support 2, and the other end is connected to the main beam 13; universal wheels 12 are installed at the bottom of the upper horizontal support 11; the lower platform 3 includes a base plate 9 and two lower horizontal supports 31 arranged at intervals; one end of the lower horizontal support 31 is connected to the vertical support 2; the base plate 9 is installed between the two lower horizontal supports 31; a guardrail assembly is installed on the lower horizontal support 31.

[0023] The upper horizontal support 11 refers to the transverse support structure that bears the load of the main beam 13. It can be formed by splicing I-beams and arranged at intervals to create a stable support frame, reducing material usage. The casters 12 are steerable rolling devices installed at the bottom of the upper horizontal support 11, such as heavy-duty rollers with braking function, enabling the entire hanging basket device to move autonomously. It should be noted that the casters 12 should have a directional locking function; once the direction is adjusted, they can be locked to allow movement in the adjusted direction. The lower horizontal support 31 refers to the transverse support structure that bears the base plate 9. It can be constructed using channel steel 21 or I-beams, and two sets of spaced-out structures form a rigid support surface. The guardrail assembly refers to the enclosure structure composed of vertical railings 32 and horizontal railings 33, such as detachable steel pipe railings, to prevent workers from falling. The vertical support 2 refers to the vertical load-bearing component connecting the upper and lower platforms 3, such as a double channel steel 21 combination structure, forming a stable force transmission path.

[0024] Specifically, the upper platform 1 forms a spatial truss structure through the main beam 13 and two sets of spaced upper horizontal supports 11. The load is transferred to the lower platform 3 through the vertical supports 2. The casters 12 allow the device to slide along the track without the need for hoisting equipment. The lower platform 3 is fixed to the base plate 9 by two sets of lower horizontal supports 31, forming an independent working surface and creating a layered working space with the upper platform 1. The guardrail assembly is bolted to the lower horizontal supports 31, and its installation position can be adjusted according to construction needs. The vertical supports 2 adopt a double-channel steel 21 combination structure, connected by angle steel to form a closed frame, enhancing overall stability. In this embodiment, the sliding hanging basket device optimizes the load distribution path through a layered platform design, reduces redundant components, and lowers its weight; the casters 12 enable autonomous sliding, significantly improving movement efficiency; and the layered platform design ensures that the upper and lower working surfaces do not interfere with each other, improving space utilization. The modular connection between the upper platform 1, the lower platform 3, and the vertical support 2 allows for rapid assembly and disassembly of the hanging basket device to the bridge section, adapting to construction needs of different spans; please refer to... Figure 4 When in use, the two hanging basket devices are hung as a whole at both ends of the bridge, and can be moved on the bridge for construction using casters.

[0025] Optionally, the upper platform 1 also includes reinforcing angle steel 5; multiple reinforcing angle steels 5 are spaced apart along the extension direction of the upper horizontal support 11, and the two ends of the reinforcing angle steel 5 are respectively welded to the two upper horizontal supports 11.

[0026] Among them, the reinforcing angle steel 5 refers to a steel component with an L-shaped cross-section, specifically made of Q235B angle steel with a thickness of 5-8mm and a right-angle side length of 50-80mm. This component forms a transverse rigid connection through welding, used to improve the structural integrity between the two upper horizontal supports 11. The spaced arrangement means that the distance between adjacent reinforcing angle steels 5 is set at 1.2-1.8m, which can be achieved through equidistant or non-equidistant arrangement, optimizing material usage while ensuring structural strength.

[0027] Specifically, a transverse rigid connection structure is formed by welding reinforcing angle steels 5 at intervals along the extension direction of the upper horizontal support 11. The welding method ensures that the two sets of supports form an integral load-bearing frame, and the shear force generated by construction loads is evenly distributed to adjacent support units. The L-shaped cross-section of the reinforcing angle steel 5 provides better bending stiffness when subjected to bending moments, effectively suppressing local deformation at the I-beam splice joints. The interval arrangement forms a support grid in key stress areas, avoiding material redundancy while maintaining structural stability. By adding transverse reinforcing angle steels 5, independent supports are transformed into a spatial frame structure, reducing the structural self-weight by approximately 15%-20% under the same load conditions, while eliminating slippage and jamming caused by support deformation. Furthermore, the interval arrangement of the reinforcing angle steels 5 forms rigid constraints at key nodes, preventing weld cracking caused by local stress concentration, and reducing steel consumption. The welding connection method enables the two sets of supports to form a collaborative load-bearing system, significantly improving the overall structural load-bearing capacity.

[0028] Optionally, both the upper horizontal support 11 and the lower horizontal support 31 are composed of multiple I-beams spliced ​​together in a straight line.

[0029] I-beams refer to steel structural members with a standard cross-sectional shape, specifically 32a type I-beams, whose cross-sectional characteristics optimize the weight of a single piece while ensuring support stiffness. Straight-line splicing refers to connecting multiple I-beams end-to-end to form a continuous support structure through welding or bolting, specifically using end-plate butt joints, thus forming a scalable modular support system.

[0030] Specifically, the standardized cross-section design of I-beams gives them a predetermined load-bearing capacity. When a continuous support structure is formed by straight splicing, the mechanical properties of each I-beam segment are uniformly transferred. During construction, the support length can be increased or decreased according to the actual span requirements without cutting or modifying the overall structure. End plates at the splicing nodes ensure the continuity of the force transmission path while retaining the possibility of segmented assembly and disassembly. This modular construction method allows the horizontal support system to quickly adapt to different span conditions, and the weight of a single I-beam component is kept within the manageable range for manual or mechanical hoisting. Modular splicing of I-beams avoids material waste caused by span changes in the overall steel profile and reduces the weight of a single hoisting unit. The continuous support system formed by splicing maintains structural integrity while enabling flexible configuration of components as needed. The reuse of standardized components reduces material waste and improves construction economy.

[0031] Optionally, an upper-level diagonal reinforcing support 4 is provided between the upper-level horizontal support 11 and the vertical support 2.

[0032] The upper-level diagonal reinforcing support 4 refers to the diagonal member connecting the horizontal support and the vertical support 2 at the node. It can be formed by welding I-beams or steel pipes, and it converts the horizontal load into axial force to be transmitted to the vertical support 2. This support forms a triangular support structure through diagonal arrangement, which effectively disperses the bending moment load generated when the upper platform 1 moves.

[0033] Specifically, the two ends of the diagonal reinforcing support are fixed to the upper horizontal support 11 and the vertical support 2, respectively, forming a stable triangular force-bearing system. When the hanging basket device moves, the lateral load borne by the horizontal support is converted into axial tension or compression through the diagonal support, and transmitted along the axis of the member to the channel steel 21 structure of the vertical support 2. This force transmission method reduces the bending deformation of the horizontal support and avoids excessive deflection at the mid-span of the horizontal support. Since the diagonal support only bears axial force, its cross-sectional dimensions can be optimized, and the amount of material used can be reasonably controlled while ensuring structural rigidity. By adding diagonal supports to construct a triangular stable structure, the bending stiffness of the horizontal support is significantly improved without increasing the longitudinal support members, solving the safety hazards caused by structural deformation during movement; effectively suppressing the deformation amplitude of the upper platform 1 when the hanging basket moves, keeping the connection node between the main beam 13 and the upper horizontal support 11 in a stable stress state, avoiding weld cracking due to local stress concentration, and ensuring the safety of construction personnel when working at height.

[0034] Optionally, the vertical support 2 includes two channel steels 21; the two channel steels 21 are spaced apart and connected at both ends by angle steel to form a closed frame; the upper horizontal support 11 is connected to one side of the channel steels 21.

[0035] Among them, channel steel 21 refers to long strips of steel with a U-shaped cross-section, which can be made of standard steel. Its symmetrical distribution characteristics can optimize the structural force path and reduce the moment concentration of individual components. Angle steel connection refers to fixing the upper and lower ends of two channel steels 21 with L-shaped steel, which can be achieved by welding or bolting, forming a closed frame to enhance the overall torsional resistance and avoid the deformation risk caused by loose joints in traditional welded trusses. The closed frame refers to a rectangular structure formed by channel steel 21 and angle steel, which can be achieved through rigid joints at the four corners, thereby increasing the overall stiffness of the vertical support 2 by constraining the relative displacement of the channel steels 21. Single-sided connection of channel steel 21 means that the upper horizontal support 11 is fixed only to one side of the channel steel 21, which can be achieved by welding or bolting, reserving installation space for the ladder assembly and separating the force transmission path from the functional area.

[0036] Specifically, two channel steels 21 are spaced apart to form the main body of the vertical support 2. Connected by angle steels at the upper and lower ends, they form a closed frame structure, allowing the load to be symmetrically transferred along the channel steels 21, reducing local stress concentration. The rigid nodes of the closed frame constrain the relative displacement of the channel steels 21, enhancing torsional resistance and avoiding the deformation risk caused by loose nodes in traditional trusses. The upper horizontal support 11 is connected to only one side of the channel steels 21, ensuring a clear force transmission path while providing space for the installation of auxiliary structures, achieving modular and rapid assembly / disassembly requirements. This embodiment utilizes a combination of channel steels 21 and angle steel, employing a closed frame to improve overall rigidity and reduce the number of supporting components; simultaneously, the single-sided connection design makes the structural layout more compact, reducing the complexity of assembly / disassembly during span adjustments. This solves the problem of low load-bearing efficiency caused by the poor overall integrity of traditional vertical supports 2, improves torsional resistance through the closed frame, reduces material usage, and allows for modular construction to adapt to different span requirements, enabling rapid assembly / disassembly and functional expansion.

[0037] Optionally, a ladder assembly is provided on the side of the channel steel 21 away from the upper horizontal support 11; the ladder assembly includes a ladder crossbar 10 and a ladder vertical bar 7; the two ladder vertical bars 7 are respectively connected to the side walls of the two channel steels 21 by connecting rods 6; multiple ladder crossbars 10 are arranged at intervals, and the two ends of the ladder crossbars 10 are respectively installed on the two ladder vertical bars 7.

[0038] The ladder vertical bar 7 refers to a longitudinal support member arranged perpendicular to the ground. It can be made of 20mm diameter round steel welded together and connected to the side wall of the channel steel 21 via connecting rod 6 to form a force transmission path, transferring the climbing load to the main structure of the channel steel 21. The ladder horizontal bar 10 refers to a horizontally arranged footrest member. It can be made of 16mm diameter threaded steel spaced 300mm apart and fixed at both ends to the ladder vertical bar 7 by welding or bolting, forming an ergonomic step spacing. The connecting rod 6 is a transition component connecting the ladder vertical bar 7 and the channel steel 21. It can be made of L-shaped angle steel, with one end welded to the web of the channel steel 21 and the other end connected to the ladder vertical bar 7, forming a triangular stable structure.

[0039] Specifically, the ladder vertical bar 7 is rigidly connected to the side wall of the channel steel 21 via connecting rod 6, utilizing the structural strength of the channel steel 21 itself as the supporting foundation, avoiding the need for a separate supporting frame. Ladder horizontal bars 10 are arranged between the two vertical bars at standard step intervals, forming a continuous climbing path. The channel steel 21 and the ladder assembly are welded together to form an integral structure. The climbing load is transferred to the web of the channel steel 21 via connecting rod 6, and then distributed to the entire hanging basket system via the vertical support 2. This integrated design eliminates the need for additional supporting components, creating a safe passage while maintaining a lightweight structure. This embodiment integrates the passage function into the load-bearing channel steel 21 through structural reuse, eliminating the need for temporary support erection and reducing material transportation and on-site welding work.

[0040] Optionally, an oblique bracing stiffener 22 is provided between the two channel steels 21.

[0041] The diagonal bracing stiffener 22 refers to the cross-bracing structure connecting two parallel channel steels 21. It can be constructed from angle steel or welded steel plates, forming a stable triangular or X-shaped bracing system. This structure, by increasing the lateral connection between the channel steels 21, transforms vertical loads into diagonal pressure, thereby enhancing the overall frame's resistance to lateral displacement. The channel steel 21 refers to long strip steel with a U-shaped cross-section; standard channel steels 21, such as No. 16 or No. 20 channel steels, can be used. The grooved structure of the channel steel 21 facilitates the welding and fixing of the diagonal bracing stiffener 22, while its lateral web can withstand the bending stress generated during construction.

[0042] Specifically, after welding the diagonal bracing stiffener 22 between the two parallel channel steels 21, the originally independent channel steels 21 are connected into a rigid whole. When the hanging basket device bears construction loads, the diagonal bracing stiffener 22, through the principle of triangular stability, transforms the shear force generated by the load into tensile and compressive forces along the support axis, thereby suppressing the lateral bending deformation of the channel steel 21. For example, under dynamic loads, the diagonal bracing stiffener 22 disperses stress concentration through its intersection nodes, preventing local buckling of the web of the channel steel 21. Furthermore, this structure optimizes the force transmission path of the vertical support 2, enabling the load to be evenly transmitted to the lower platform 3, reducing the risk of cracking at the welded joints due to stress concentration.

[0043] Optionally, the guardrail assembly includes vertical railings 32 and horizontal railings 33; multiple vertical railings 32 are spaced apart and are all vertically installed on the surface of the lower horizontal support 31; multiple horizontal railings 33 are installed between adjacent vertical railings 32.

[0044] The vertical railings 32 are upright support components perpendicular to the platform surface. They can be made of square steel pipes or angle steel and fixed to the surface of the lower horizontal support 31 with bolts. The spacing between them can be adjusted according to construction specifications. This structure forms a vertical rigid support through multi-point fixing, preventing deformation caused by lateral impacts. The horizontal railings 33 are components that horizontally connect adjacent vertical railings 32. They can be made of round steel pipes or channel steel 21 and installed by welding or snap-fit ​​methods. The horizontal railings 33 are arranged in layers in the vertical direction, forming multiple continuous protective surfaces and eliminating gaps between the vertical railings 32.

[0045] Specifically, vertical railings 32 are fixed at preset intervals to the edge of the lower horizontal support 31, forming a vertical protective frame. Horizontal railings 33 are installed in layers between adjacent vertical railings 32, for example, one at a height of 0.5 meters and another at a height of 1 meter from the platform surface, forming rigid nodes with the vertical railings 32 via end connectors. This arrangement allows the vertical railings 32 to bear lateral loads, while the horizontal railings 33 bear horizontal loads, together forming a spatial truss structure. During construction, the lateral force generated by workers leaning against the guardrails is distributed through the horizontal railings 33 to multiple vertical railings 32, and then transferred to the load-bearing system of the lower horizontal support 31, preventing excessive local stress. This embodiment effectively eliminates the safety hazard of excessive gaps in the guardrails, preventing construction workers and materials from falling laterally from the platform. The formed grid-like protective structure can withstand the lateral loads generated by personnel leaning against it, preventing plastic deformation of the guardrails. The modular railing components can adjust the installation spacing according to different construction scenarios, adapting to the edge protection needs of bridges with various spans.

[0046] Optionally, the bottom surface of the base plate 9 is provided with multiple reinforcing angle steels 5; the two ends of the reinforcing angle steels 5 are respectively connected to two sets of lower horizontal supports 31.

[0047] The reinforcing angle steel 5 can be made by welding equal or unequal angle steel. The vertical side of the angle steel is attached to the bottom surface of the base plate 9, and the horizontal side is connected to the lower horizontal support 31. The bending stiffness of the base plate 9 is improved by utilizing the moment of inertia of the angle steel section. The connection to the two sets of lower horizontal supports 31 means that the two ends of the angle steel are welded or bolted to the flange surfaces of the I-beams of the two sets of parallel lower horizontal supports 31. The transverse connection forms a truss structure, so that the load of the base plate 9 is transferred to the lower horizontal supports 31 through the angle steel, avoiding local stress concentration.

[0048] Specifically, by arranging multiple reinforcing angle steels 5 at transverse intervals along the bottom surface of the base plate 9, the angle steels form a rigid connection frame with the I-beams of the lower horizontal supports 31. When construction loads are applied to the base plate 9, the angle steels resist the bending deformation of the base plate 9 through their vertical edges, while their horizontal edges and the flanges of the I-beams share the shear force, thereby distributing the concentrated load to the lower horizontal supports 31 on both sides. This truss-type connection method enhances the overall stiffness of the base plate 9 by utilizing the cross-sectional characteristics of the angle steel without significantly increasing the structural self-weight, suppressing local collapse or warping deformation caused by uneven loads. It effectively solves the problem of insufficient load-bearing capacity of the base plate 9 of the hanging basket platform due to the superposition of structural self-weight and loads. By improving the bending stiffness of the base plate 9 through the angle steel truss structure, it suppresses deformation caused by concrete pouring vibration or equipment movement during construction, ensuring the flatness of the working surface and construction safety, while maintaining the lightweight characteristics of the lower platform 3 to meet the sliding efficiency requirements.

[0049] Optionally, a lower-level diagonal reinforcing support 8 is provided between the lower-level horizontal support 31 and the vertical support 2.

[0050] The lower-level diagonal reinforcing support 8 refers to the inclined member connecting the lower-level horizontal support 31 and the vertical support 2. Specifically, it can be made by diagonally welding No. 20 channel steel 21, with its inclination angle controlled between 45 degrees and 60 degrees. The triangular stable structure refers to the geometrically invariant system composed of the lower-level horizontal support 31, the vertical support 2, and the lower-level diagonal reinforcing support 8. Specifically, a stable triangular region is formed by three-point hinges. This structure can convert lateral loads into axial pressure transmission.

[0051] Specifically, when construction loads are applied to the lower platform 3, the lateral force borne by the lower horizontal support 31 is converted into axial pressure and transmitted to the vertical support 2 through the lower diagonal reinforcing support 8. Due to the geometric stability of the triangular structure, the overall stiffness of the lower platform 3 is enhanced, and the bending deformation of the horizontal support is controlled within the allowable range. This force transmission mechanism allows for the optimization of the cross-sectional dimensions of the horizontal support, reducing the amount of steel used while ensuring load-bearing capacity, thereby reducing the self-weight of the device. In mobile applications, the increased structural stiffness avoids the need for temporary supports due to excessive deformation, as is common in traditional hanging baskets.

[0052] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
