Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, specifically to a step-climbing platform and its deformable frame structure. Background Technology
[0002] With the rapid development of roads and bridges, infrastructure construction is also changing rapidly. There is an increasing number of bridges being built, including those that need to take into account both aesthetics and design, with the towers designed to be twisted and tilted.
[0003] While the tower's twisted and tilted shape is aesthetically pleasing, it presents significant construction challenges. The tower is typically constructed from multiple segments, each requiring assembly and welding after ground fabrication. Because the overall tower is a near-circular, twisted, and tilted structure, assembling it is difficult. Using aerial work platforms or scaffolding would not only be a massive undertaking, time-consuming and labor-intensive, but also pose safety risks, require a demanding working environment, and be extremely inconvenient for workers. Utility Model Content
[0004] Therefore, it is necessary to provide a stepping climbing platform and its deformable frame structure to address the problem that bridge towers are twisted and tilted, making them difficult to construct during the splicing process.
[0005] A deformable frame structure, comprising:
[0006] Two sets of load-bearing frames are arranged in parallel with a gap between them. Each load-bearing frame is a parallelogram structure, and its four sides are hinged in sequence.
[0007] A support platform, wherein both ends of the support platform are respectively located at the top edges of the two sets of support frames; and
[0008] A telescopic drive component is disposed within the load-bearing frame, and the telescopic drive component drives the load-bearing frame to deform in order to keep the load-bearing platform horizontal.
[0009] In one embodiment, the load-bearing frame includes two sets of parallel crossbeams and two sets of vertical rods. The two sets of vertical rods are respectively hinged to the ends of the two sets of crossbeams. One end of the telescopic drive member is hinged to the vertical rod, and the other end of the telescopic drive member is hinged to the crossbeam.
[0010] In one embodiment, the two ends of the support platform are a fixed end and a movable end, respectively. The fixed end of the support platform is hinged to the top edge of one of the support frames, and a limit frame is installed on the top edge of the other support frame. The movable end of the support platform is movably inserted into the limit frame.
[0011] In one embodiment, the movable end of the support platform is provided with rollers, which are used to contact the inner wall of the limiting frame.
[0012] In one embodiment, the bearing platform includes two parallel bearing beams and a crossbar connecting the two bearing beams, and the limiting frame is provided in two sets, with the two bearing beams respectively inserted into the two limiting frames.

[0034] Please see Figure 1 One embodiment of the step-climbing platform includes a deformable frame structure 30, which is used to support the upper working platform 50 during the construction of the tower.
[0035] In one embodiment, the deformable frame structure 30 includes two sets of load-bearing frames 31, a load-bearing platform 40, and a telescopic drive member 32. Two sets of load-bearing frames 31 are provided, and the two sets of load-bearing frames 31 are arranged parallel to each other at intervals. The load-bearing frames 31 have a parallelogram structure, and the four sides of the load-bearing frames 31 are hinged sequentially.
[0036] Please refer to the following: Figure 2 Specifically, the load-bearing frame 31 includes two sets of parallel crossbeams 312 and two sets of vertical rods 314, wherein the two ends of the vertical rods 314 are hinged to the ends of the upper and lower crossbeams 312 respectively, thereby forming a deformable parallelogram structure. The vertical rods 314 are connected to the stepping climbing mechanism 20, which can drive the deformable frame structure 30 to move up and down.
[0037] The two ends of the support platform 40 are respectively located at the top edges of the two sets of support frames 31. The telescopic drive component 32 is located inside the support frame 31. The telescopic drive component 32 drives the support frame 31 to deform, so as to keep the support platform 40 horizontal. Among them, such as Figures 3 to 5 As shown, when the tower body tilts and twists, the telescopic drive 32 can drive the bearing frame 31 to deform. Since the bearing frame 31 is a parallelogram structure, even if the bearing frame 31 deforms, the top edge can remain horizontal, thereby ensuring that the bearing platform 40 on the top edge is horizontal.
[0038] In one embodiment, the two ends of the support platform 40 are a fixed end 41 and a movable end 42, respectively. The fixed end 41 of the support platform 40 is hinged to the top edge of one of the support frames 31, and a limit frame 43 is installed on the top edge of the other support frame 31. The movable end 42 of the support platform 40 is inserted into the limit frame 43. Wherein, as... Figures 6 to 8 As shown, when the tower body is in a twisted state, the tracks on the tower body are no longer parallel to each other. One end of the bearing platform 40 is hinged to the bearing frame 31, and the other end of the bearing platform 40 can move within the limit frame 43, releasing multiple degrees of freedom, so that the bearing platform 40 can adapt to the twisting of the tower body and prevent jamming.
[0039] In one embodiment, the movable end 42 of the support platform 40 is provided with a roller 46, which is used to contact the inner wall of the limiting frame 43. The movable end 42 of the support platform 40 moves within the limiting hole via the roller 46, which facilitates the free movement of the support platform 40 and avoids hard contact between the movable end 42 and the inner wall of the limiting frame 43, thus preventing damage to the limiting frame 43.
[0040] In one embodiment, the support platform 40 includes two parallel support beams 44 and a crossbar 45 connecting the two support beams 44. One end of each support beam 44 is hinged to the crossbeam 312 of the support frame 31 via a hinge seat. Two sets of limiting frames 43 are designed, and the two support beams 44 are respectively inserted into the two limiting frames 43 to ensure the stability of the support platform 40 during movement.
[0041] Please see Figure 2 and Figure 3 In one embodiment, the deformable frame structure 30 further includes a tilt sensor 33, which is mounted on the support frame 31. Specifically, the tilt sensor 33 is mounted on the crossbeam 312 at the top edge of the support frame 31. The tilt sensor 33 is used to detect the tilt state of the deformable frame structure. When the deformable frame structure 30 is tilted, the telescopic drive 32 lifts and retracts the support frame 31, adjusting it to a horizontal position, ultimately ensuring that the support platform 40 is level.
[0042] In one embodiment, the deformable frame structure 30 further includes an electrical control platform 34. One end of the electrical control platform 34 is hinged to the bottom edge of one of the supporting frames 31, and the bottom edge of the other supporting frame 31 is provided with a limiting frame 43. The other end of the electrical control platform 34 is inserted into the limiting frame 43. The electrical control platform 34 is used to install control components for the supporting stepping lifting platform, etc. Similar to the principle of the supporting platform 40, one end of the electrical control platform 34 is hinged to the supporting frame 31, and the other end of the electrical control platform 34 can move within the limiting frame 43, releasing multiple degrees of freedom, so that the electrical control platform 34 can adapt to the twisting of the tower body and prevent jamming.
[0043] In one embodiment, the deformable frame structure 30 further includes a protective railing 35, which connects two sets of load-bearing frames 31. The protective railing 35 is located on the side of the load-bearing frame 31 to ensure the safety of personnel working on the electric control platform 34.
[0044] In one embodiment, the telescopic drive member 32 is an electric telescopic rod. It is understood that in other embodiments, the telescopic drive member 32 may also employ other structures capable of lifting and lowering, such as a lifting hydraulic cylinder. Two sets of telescopic drive members 32 are provided, each set housed within one of two supporting frames 31, to synchronously drive the two sets of supporting frames 31 to deform synchronously.
[0045] In the aforementioned step-climbing platform and deformable frame structure 30, after the tower tilt angle changes, the tilt sensor 33 outputs a signal, and the telescopic drive component 32 can drive the bearing frame 31 to deform, ensuring the horizontality of the upper bearing platform 40. When the tower is in a twisted state, the tracks on the tower are no longer parallel to each other. One end of the bearing platform 40 is hinged to the bearing frame 31, and the other end of the bearing platform 40 can move within the limiting frame 43, releasing multiple degrees of freedom, allowing the bearing platform 40 to adapt to the tower twist and preventing jamming. The aforementioned step-climbing platform and deformable frame structure 30, with the bearing platform 40 cooperating with the bearing frame 31 to change structure, keeps the working platform 50 above the bearing platform 40 in a nearly horizontal state, solving the problems of construction difficulties, high safety risks, long construction periods, and high costs caused by the tilt and twisting of the tower itself.
[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
