Abstract
Description
Technical Field
[0001] This utility model relates to the field of attached lifting scaffolding technology, specifically to an adjustable climbing scaffold guide wheel multimodal adjustable climbing scaffold support. Background Technology
[0002] The structure of an attached lifting scaffold mainly consists of the frame, attachment supports, lifting system, and safety devices. The coordinated design of the guide wheels and guide rails is crucial for safe lifting. The guide rails are typically rigid metal tracks, vertically fixed to the building facade or connected to the main building structure via attachment supports, providing a precise vertical path reference for the scaffold's lifting and preventing deviation or swaying. The guide wheels are mounted on the frame and engage with the guide rails through multi-point rolling contact, reducing frictional resistance during lifting and constraining horizontal displacement of the scaffold, ensuring smooth lifting.
[0003] Existing attached lifting scaffolding has several problems. First, the guide wheels are poorly adaptable to changes in guide rail dimensions. Traditional guide wheels use a fixed structure design. When the guide rail deforms due to construction errors or the pre-embedded wall-mounted support through-wall bolt holes deviate significantly, or when the wall-mounted support and guide rail are not installed according to the design drawings, jamming or excessive gaps can easily occur between the guide wheels and guide rails. This is especially true when running on non-standard guide rails such as curved or irregular shapes, where the wheel-rail contact surface cannot maintain dynamic fit or the required gap, causing the scaffold to sway beyond the safety threshold. This can lead to severe deformation or breakage of the guide wheel axle when the upper and lower plates of the guide wheel support cut the guide rail tube or the anti-tipping guide wheel axle. Second, existing wall-mounted supports integrate the load-bearing mechanism and adjustment device. When a single part inside the support is damaged, the entire support must be disassembled and replaced. In a working environment at a height of 100 meters, this "one-size-fits-all" maintenance method significantly increases construction risks and time costs. Utility Model Content
[0004] Therefore, in order to solve the above problems, the purpose of this utility model is to provide an adjustable climbing scaffold guide wheel, comprising:
[0005] An elastic jacket, wherein the elastic jacket is hollow.
[0006] The guide wheel base is disposed in the middle of the elastic outer sleeve. The guide wheel base includes a circumferentially arranged base support block. Two adjacent base support blocks are connected by a connecting piece, and an adjustment gap is formed between two adjacent base support blocks.
[0007] A guide wheel insert is disposed in the middle of the elastic outer sleeve. The guide wheel insert includes a circumferentially arranged insert support block, which is disposed in the adjustment gap and is connected to the inner edge of the elastic outer sleeve by a spring.
[0008] A guide wheel adjusting slider is disposed in the middle of the guide wheel base. The guide wheel adjusting slider includes an adjusting inclined surface, which abuts against the insert support block.
[0009] Preferably, the inward-facing side of the insert support block has an embedding groove that can cooperate with the connecting piece.
[0010] Preferably, the side of the adjusting slope is provided with a guide protrusion, and the base support block is provided with a guide groove that can cooperate with the guide protrusion.
[0011] This utility model also provides a multimodal adjustable climbing scaffold support, including a support body, guide wheel seats and the aforementioned adjustable climbing scaffold guide wheels. The two guide wheel seats are symmetrically installed on the support body, and the adjustable climbing scaffold guide wheels are installed on the guide wheel seats.
[0012] As one embodiment of the multimodal adjustable climbing scaffold support of this utility model, the guide wheel seat includes a first seat body and a second seat body. The first seat body is fixed to the support body, and the second seat body is connected to the first seat body through a side plate. Adjustable climbing scaffold guide wheels are installed in both the first and second seat bodies. A gap is formed between the first and second seat bodies for the guide rail to be inserted, and the adjustable climbing scaffold guide wheels abut against the climbing scaffold guide rail.
[0013] Preferably, the adjustable climbing scaffold guide wheel is connected to the guide wheel seat through an adjustment mechanism. The adjustment mechanism includes an adjustment base and a bearing connecting seat. The two ends of the adjustment base and the bearing connecting seat are connected to each other through an adjustment telescopic rod. An adjustment spring is sleeved on the adjustment telescopic rod. The bearing connecting seat is connected to the adjustable climbing scaffold guide wheel through a bearing and a rotating shaft.
[0014] As one embodiment of the multimodal adjustable climbing scaffold support of this utility model, the guide wheel seat includes a first seat body and a side seat body. The side seat body is fixed to the side of the first seat body, and an adjustable climbing scaffold guide wheel and a conical auxiliary wheel are connected to the side seat body. The adjustable climbing scaffold guide wheel and the conical auxiliary wheel are coaxial and abut against the climbing scaffold guide rail.
[0015] Preferably, a fall-prevention swing block is connected to the middle of the support body.
[0016] The beneficial effects of this utility model are:
[0017] This technical solution effectively solves the problems of poor adaptability and high maintenance costs of existing attached lifting scaffold guide wheels through the coordinated design of adjustable climbing scaffold guide wheels and multimodal adjustable supports. Specifically, the elastic outer sleeve of the guide wheel and the internal adjustment structure form a dynamic adaptive system: the elastic outer sleeve buffers the impact of local deformation of the guide rail through deformation, while the adjusting slider extends and retracts within the adjustment gap through the inclined plane and spring-driven insert support block. This allows the guide wheel insert to adjust the contact pressure and gap in real time according to changes in the guide rail size, ensuring that the wheel-rail contact surface is always tightly fitted. Especially when running on curved or irregularly shaped guide rails, it avoids the risk of scaffold swaying, wheel axle deformation, or breakage caused by jamming or excessive gaps in traditional rigid guide wheels. At the same time, the modular design of the guide wheel seat decouples the load-bearing mechanism and the adjustment device. Fine-tuning of the guide wheel position is achieved by adjusting the telescopic rod and bearing connection seat, allowing replacement of damaged parts without overall disassembly, significantly reducing the risk and time cost of high-altitude maintenance. The overall technical solution improves the adaptability of the guide rollers to construction errors and complex structures, while taking into account construction safety and ease of maintenance, providing a reliable guarantee for efficient construction of high-rise buildings.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0036] Example 1:
[0037] Figures 1-5 This invention provides an adjustable climbing scaffold guide wheel 1, comprising an elastic outer sleeve 11, a guide wheel base, a guide wheel insert, and a guide wheel adjusting slider 15. The elastic outer sleeve 11 is hollow, with its central portion used to mount the guide wheel base and the guide wheel insert. The guide wheel base is located in the middle of the elastic outer sleeve 11. The guide wheel base includes a circumferentially arranged base support block 12, with adjacent base support blocks 12 connected by a connecting piece 13, forming an adjusting gap between adjacent base support blocks 12. The guide wheel insert includes a circumferentially arranged insert support block 14, which is located in the adjusting gap and connected to the inner edge of the elastic outer sleeve 11 by a spring 17. The guide wheel adjusting slider 15 is located in the middle of the guide wheel base and includes an adjusting inclined surface 16 that abuts against the insert support block 14.
[0038] When the contact state between the guide wheel and the guide rail needs to be adjusted, the guide wheel adjusting slider 15 moves along the axial direction, and its adjusting inclined surface 16 contacts the guide wheel insert's insert support block 14, converting the axial displacement into a radial component force. If the guide wheel adjusting slider 15 retracts towards the center, the inclined surface pushes the insert support block 14 radially outward, compressing the spring 17 and forcing the guide wheel insert to expand, thereby increasing the outer diameter of the guide wheel to accommodate excessive guide rail clearance; conversely, if the adjusting slider moves outward, the pressure of the inclined surface decreases, the spring 17 rebounds and pulls the insert support block 14 inward, the guide wheel insert retracts to reduce the outer diameter, relieving the jamming caused by local deformation of the guide rail. The guide wheel adjusting slider 15 is fixed in its specific position by the clamp 19. The clamp 19 has matching bolt holes. When the bolts are inserted into the bolt holes and tightened, the clamp 19 contracts radially, clamping itself onto the rotating shaft 18 for axial locking. When axially locked, the radial pressure of the clamp 19's ring acts on the guide wheel shaft surface, creating frictional fixation. Its annular end face supports the guide wheel adjusting slider 15 for axial positioning. Two clamps 19 are required to be used, axially locking them on both sides of the rotating shaft 18 to limit the degree to which the guide wheel adjusting slider 15 is embedded in the guide wheel, thereby controlling the guide wheel's outer diameter. The elastic outer sleeve 11 buffers impact through its own deformation and works in conjunction with the spring 17 to complete the reset action, ultimately achieving dynamic adjustment of the guide wheel's outer diameter within a reasonable range, accurately compensating for construction errors and guide rail deformation.
[0039] The inward-facing side of the insert support block 14 has an embedding groove 141 that can cooperate with the connecting piece 13. The embedding groove 141 of the slider support block, which cooperates with the connecting piece 13, forms a rigid constraint on the radial movement trajectory of the slider support block through the groove, restricting its circumferential rotational offset. This ensures that the slider support block always extends and retracts within the adjustment gap along the preset direction, avoiding misalignment, disengagement, or even jamming caused by centrifugal force or uneven force. At the same time, the positioning function of the connecting piece 13 maintains the alignment between the slider support block and the guide wheel base, ensuring the synchronization and coordination of the adjustment actions of multiple sets of guide wheel inserts, thereby improving the accuracy and reliability of the overall dynamic adaptation of the guide wheel.
[0040] The side of the adjusting ramp 16 is provided with a guide protrusion 161, and the base support block 12 is provided with a guide groove 121 that can cooperate with the guide protrusion 161. The cooperation between the guide protrusion 161 of the adjusting ramp 16 and the guide groove 121 of the base support block 12 forms a rigid guide constraint for axial movement: the guide protrusion 161 slides within the guide groove 121, limiting the rotation or circumferential offset of the guide wheel adjusting slider 15 during axial movement, ensuring that the adjusting ramp 16 always maintains a preset contact angle with the slider support block, avoiding force transmission failure or local jamming caused by rotational misalignment. At the same time, the linear trajectory of the guide groove 121 accurately guides the displacement direction of the adjusting slider, improving the efficiency and stability of the ramp transmission, and reducing the risk of wear or asynchronous adjustment actions caused by off-center loading.
[0041] See Figure 5 Multiple adjustable climbing frame guide wheels 1 can be connected to the same rotating shaft 18 at the same time. When the width of the on-site guide rail is small, only one guide wheel needs to be used for assembly. When the width of the on-site guide rail surface is large, two guide wheels are combined for assembly, which can fit the wide guide rail surface.
[0042] Example 2:
[0043] This embodiment provides a multimodal adjustable climbing scaffold support, including a support body 2, guide wheel seats 3, and adjustable climbing scaffold guide wheels 1 as shown in Embodiment 1. Two guide wheel seats 3 are symmetrically mounted on the support body 2. The adjustable climbing scaffold guide wheels 1 are mounted on the guide wheel seats 3. The guide wheel seats 3 include a first seat body 31 and a second seat body 32. The first seat body 31 is fixed to the support body 2, and the second seat body 32 is connected to the first seat body 31 through a side plate 33. Adjustable climbing scaffold guide wheels 1 are installed in both the first seat body 31 and the second seat body 32. A gap is formed between the first seat body 31 and the second seat body 32 for the guide rail to engage. The adjustable climbing scaffold guide wheels 1 abut against the climbing scaffold guide rail 5. The multimodal climbing scaffold support provided in this embodiment adopts a modular split design. Different styles of guide wheel seats 3 can be assembled by quickly disassembling and assembling the first seat body 31, the second seat body 32, and the side plate 33 to cope with guide rail construction deviations or special guide rail structures. If a seat, guide wheel, or side plate 33 is damaged, the faulty component can be replaced individually by disconnecting the corresponding module, without dismantling the overall structure or affecting the function of adjacent modules. This modular design decouples the load-bearing, adjustment, and adaptation functions of the support, enabling efficient maintenance with "replace and use immediately" in high-altitude environments, and allowing for rapid reconfiguration of the guide wheel configuration according to construction needs, significantly improving adaptability to complex guide rails and construction fault tolerance.
[0044] In this embodiment, the first seat 31, the second seat 32, and the side plate 33 together form a "C"-shaped guide wheel seat 3, which can be adapted to the climbing frame guide rail 5 with a corresponding special structure, such as... Figure 7 , Figure 9 , Figure 10 , Figure 11 .
[0045] See Figure 8 The adjustable climbing scaffold guide wheel 1 is connected to the guide wheel seat 3 via an adjustment mechanism 6. The adjustment mechanism 6 includes an adjustment base 61 and a bearing connecting seat 62. The two ends of the adjustment base 61 and the bearing connecting seat 62 are connected to each other via an adjustment telescopic rod 63. An adjustment spring 64 is fitted on the adjustment telescopic rod 63. The bearing connecting seat 62 is connected to the adjustable climbing scaffold guide wheel 1 via a bearing and a rotating shaft 18. The clamping force of the guide wheel is finely adjusted by the adjustment mechanism 6 so that the guide wheel can be pressed tightly against the surface of the climbing scaffold guide rail 5, ensuring that the climbing scaffold guide rail 5 is accurately engaged in the gap and evenly stressed.
[0046] A fall-prevention block 4 is connected to the middle of the support body 2. The fall-prevention block 4 is used to prevent the support from falling accidentally and to ensure construction safety.
[0047] Example 3:
[0048] This embodiment provides a multimodal adjustable climbing scaffold support. The difference between this embodiment and embodiment 2 is that the specific style of the guide wheel seat 3 is changed. Specifically, the guide wheel seat 3 in this embodiment includes a first seat body 31 and a side seat body 34. The side seat body 34 is fixed to the side of the first seat body 31. An adjustable climbing scaffold guide wheel 1 and a conical auxiliary wheel 35 are connected to the side seat body 34. The adjustable climbing scaffold guide wheel 1 and the conical auxiliary wheel 35 are coaxial and abut against the climbing scaffold guide rail 5.
[0049] This embodiment makes good use of the modular design of the guide wheel seat 3, changing the style of the guide wheel seat 3 and equipping it with an auxiliary wheel 35, which can be adapted to the triangular climbing frame guide rail 5, see Figure 12 .

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
