Description

Technical Field

[0001] The present invention relates to the technical field of attached lifting scaffolds, and specifically to an adjustable climbing frame guide wheel multi-modal adjustable climbing frame support seat. Background Art

[0002] The structure of an attached lifting scaffold mainly consists of a scaffold body, an attached support seat, a lifting system, and safety devices, etc. Among them, the collaborative design of the guide wheel and the guide rail is the core to achieve its safe lifting. The guide rail is usually a rigid metal track, which is vertically fixed on the building facade or connected to the main building structure through the attached support seat, providing an accurate vertical path reference for the lifting of the scaffold body and preventing deviation or shaking. The guide wheel is installed on the scaffold body and engages with the guide rail through multi-point rolling contact, which not only reduces the frictional resistance during the lifting process but also restricts the horizontal displacement of the scaffold body to ensure smooth lifting.

[0003] There are certain problems with the existing attached lifting scaffolds. First, the adaptability of the guide wheel to the dimensional changes of the guide rail is poor. The traditional guide wheel adopts a fixed structure design. When the guide rail deforms due to construction errors or the position deviation of the embedded wall-attached support seat through-wall bolt holes is large, and the wall-attached support seat and the guide rail are not installed according to the design drawings, it is easy to occur the phenomenon of jamming or excessive clearance between the guide wheel and the guide rail. Especially when running on non-standard guide rails such as arc-shaped and special-shaped ones, the contact surface between the wheel and the rail cannot maintain dynamic fit or the clearance required by the standard, resulting in the shaking amplitude of the scaffold body exceeding the safety threshold, and the upper and lower plates of the guide wheel support seat cutting the guide rail round tube or the anti-overturning guide wheel axle being severely deformed or broken. Second, the existing wall-attached support seat integrates the load-bearing mechanism and the adjustment device. When a single part inside the support seat is damaged, the entire support seat must be disassembled for replacement. In the working environment at a height of 100 meters, this "one move affects the whole body" maintenance method greatly increases the construction risk and time cost. Summary of the Invention

[0004] Therefore, in order to solve the above problems, the purpose of the present invention is to provide an adjustable climbing frame guide wheel, including:

[0005] An elastic outer sleeve, the elastic outer sleeve is hollow.

[0006] A guide wheel base body, the guide wheel base body is arranged in the middle of the elastic outer sleeve, the guide wheel base body includes circumferentially arranged base support blocks, adjacent two base support blocks are connected by connecting pieces, and an adjustment gap is formed between adjacent two base support blocks;

[0007] A guide wheel insert block, the guide wheel insert block is arranged in the middle of the elastic outer sleeve, the guide wheel insert block includes circumferentially arranged insert support blocks, the insert support blocks are arranged at the adjustment gap, and the insert support blocks are connected to the inner edge of the elastic outer sleeve through springs;

[0008] The guide wheel adjusting slider is arranged in the middle of the guide wheel base body. The guide wheel adjusting slider includes an adjusting inclined surface, and the adjusting inclined surface abuts against the inlay support block.

[0009] Preferably, an embedding groove is provided on the inner side of the inlay support block and can cooperate with the connecting piece.

[0010] Preferably, a guiding convex edge is provided on the side surface of the adjusting inclined surface, and a guiding groove is provided on the base support block and can cooperate with the guiding convex edge.

[0011] The present invention also provides a multi-modal adjustable climbing frame support, which includes a support body, a guide wheel seat and the above-mentioned adjustable climbing frame guide wheel. The two guide wheel seats are symmetrically installed on the support body, and the adjustable climbing frame guide wheel is installed on the guide wheel seat.

[0012] As an implementation manner of the multi-modal adjustable climbing frame support of the present invention, 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 frame guide wheels are installed in both the first seat body and the second seat body. A gap for the guide rail to be inserted is formed between the first seat body and the second seat body, and the adjustable climbing frame guide wheel abuts against the climbing frame guide rail.

[0013] Preferably, the adjustable climbing frame guide wheel is connected in the guide wheel seat through an adjusting mechanism. The adjusting mechanism includes an adjusting base and a bearing connecting seat. The two ends of the adjusting base and the bearing connecting seat are connected to each other through an adjusting telescopic rod. An adjusting spring is sleeved on the adjusting telescopic rod. The bearing connecting seat is connected to the adjustable climbing frame guide wheel through a bearing and a rotating shaft.

[0014] As an implementation manner of the multi-modal adjustable climbing frame support of the present invention, 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. An adjustable climbing frame guide wheel and a conical auxiliary wheel are connected to the side seat body. The adjustable climbing frame guide wheel and the conical auxiliary wheel are coaxial and abut against the climbing frame guide rail.

[0015] Preferably, an anti-falling pendulum block is connected to the middle of the support body.

[0016] The beneficial effects of the present invention are:

[0017] Through the collaborative design of adjustable climbing frame guide wheels and multi-modal adjustment supports, this technical solution effectively solves the problems of poor adaptability and high maintenance costs of existing guide wheels for attached lifting scaffolds. 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 adjustment slider drives the support block of the insert block to expand and contract in the adjustment gap through the inclined plane and the spring, enabling the insert block of the guide wheel to adjust the contact pressure and gap in real time according to the change of the guide rail size, ensuring that the contact surface between the wheel and the rail is always tightly fitted. Especially when running on arc-shaped or special-shaped guide rails, it can avoid the risks of scaffold shaking, wheel axle deformation or fracture caused by jamming or excessive gap of 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, and realizes fine adjustment of the guide wheel position through the adjustment telescopic rod and the bearing connecting seat. Damaged parts can be replaced without overall disassembly, significantly reducing the high-altitude maintenance risk and time cost. The overall technical solution improves the adaptability of the guide wheel to construction errors and complex structures while taking into account construction safety and maintenance convenience, providing a reliable guarantee for the efficient construction of high-rise buildings.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] Unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Embodiment 1:

[0037] Figures 1 - 5 An adjustable climbing frame guide wheel 1 provided by the present invention is shown, comprising an elastic sleeve 11, a guide wheel base, a guide wheel insert and a guide wheel adjustment slider 15. The elastic sleeve 11 is hollow, and the middle part thereof is used to install the guide wheel base and the guide wheel insert, and the guide wheel base is arranged in the middle of the elastic sleeve 11; the guide wheel base comprises a circumferentially arranged base support block 12, two adjacent base support blocks 12 are connected by a connecting piece 13, and an adjustment gap is formed between the two adjacent base support blocks 12; the guide wheel insert comprises a circumferentially arranged insert support block 14, the insert support block 14 is arranged at the adjustment gap, and the insert support block 14 is connected to the inner edge of the elastic sleeve 11 through a spring 17; the guide wheel adjustment slider 15 is arranged in the middle of the guide wheel base, and the guide wheel adjustment slider 15 comprises an adjustment inclined surface 16, and the adjustment inclined surface 16 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 adjustment slider 15 moves along the axial direction, and the adjustment bevel 16 on its surface contacts the insert support block 14 of the guide wheel insert, converting the axial displacement into a radial force component. If the guide wheel adjustment slider 15 shrinks toward the center, the bevel 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 adapt to the situation where the guide rail gap is too large; conversely, if the adjustment slider moves outward, the bevel pressure decreases, and the spring 17 rebounds to pull the insert support block 14 inward, and the guide wheel insert shrinks to reduce the outer diameter, alleviating the jamming caused by local deformation of the guide rail. The guide wheel adjustment slider 15 is fixed in its specific position by the clamp 19, and the jamming The hoop 19 has a matching bolt hole. The screw hole is inserted into the bolt hole and tightened to make the clamp 19 radially contract, so that it is clamped on the rotating shaft 18 and axially locked. When axially locked, the radial pressure of the clamp 19 ring body acts on the surface of the guide wheel shaft to form friction fixation, and its annular end face supports the guide wheel adjustment slider 15 to achieve axial positioning. Two clamps 19 need to be used to axially lock on both sides of the rotating shaft 18 to limit the degree to which the guide wheel adjustment slider 15 is embedded in the guide wheel, thereby controlling the outer diameter of the guide wheel. The elastic jacket 11 buffers the impact through its own deformation, and cooperates with the spring 17 to complete the reset action, and finally realizes the dynamic adjustment of the outer diameter of the guide wheel within a reasonable range, accurately compensating for construction errors and guide rail deformation.

[0039] On the inner side of the insert support block 14, there is an insertion groove 141 that can cooperate with the connecting piece 13. The insertion groove 141 provided on the inner side of the slider support block cooperates with the connecting piece 13. Through the notch, a rigid constraint is formed on the radial movement trajectory of the slider support block, restricting its circumferential rotation and deviation, ensuring that the slider support block always expands and contracts within the adjustment gap along the preset direction, and 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 centering of the slider support block and the guide wheel base, ensuring the synchronization and coordination of the adjustment actions of multiple groups of guide wheel inserts, thereby improving the accuracy and reliability of the overall dynamic adaptation of the guide wheel.

[0040] On the side of the adjusting inclined surface 16, there is a guiding convex edge 161. The base support block 12 is provided with a guiding groove 121 that can cooperate with the guiding convex edge 161. The guiding convex edge 161 of the adjusting inclined surface 16 cooperates with the guiding groove 121 of the base support block 12 to form a rigid guiding constraint for axial movement: the guiding convex edge 161 slides into the guiding groove 121, restricting the self-rotation or circumferential deviation of the guide wheel adjusting slider 15 during axial movement, ensuring that the adjusting inclined surface 16 always maintains a preset contact angle with the slider support block, and avoiding transmission failure or local jamming caused by rotational misalignment. At the same time, the linear trajectory of the guiding groove 121 precisely guides the displacement direction of the adjusting slider, improving the efficiency and stability of the inclined surface transmission, and reducing the risk of wear or asynchronous adjustment actions caused by eccentric loading.

[0041] See Figure 5 , multiple adjustable climbing guide wheels 1 can be simultaneously connected to the same rotating shaft 18. When the width of the on-site guide rail is small, only one guide wheel assembly is used. When the width of the on-site guide rail surface is large, two guide wheels are assembled in combination to cooperate with the large-width guide rail surface.

[0042] Embodiment 2:

[0043] This embodiment provides a multi-modal adjustable climbing frame support, which includes a support body 2, a guide wheel seat 3, and an adjustable climbing frame guide wheel 1 shown in Embodiment 1. Two guide wheel seats 3 are symmetrically installed on the support body 2, and the adjustable climbing frame guide wheel 1 is installed on the guide wheel seat 3. The guide wheel seat 3 includes 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. The adjustable climbing frame guide wheel 1 is installed in both the first seat body 31 and the second seat body 32. A gap for the guide rail to be inserted is formed between the first seat body 31 and the second seat body 32, and the adjustable climbing frame guide wheel 1 abuts against the climbing frame guide rail 5. The multi-modal climbing frame support provided in this embodiment adopts a modular split design. Through the quick disassembly and assembly combination of the first seat body 31, the second seat body 32, and the side plate 33, different styles of guide wheel seats 3 can be assembled to cope with construction deviations of the guide rail or special structures of the guide rail. If a certain seat body, guide wheel, or side plate 33 is damaged, only the connection of the corresponding module needs to be released, and the faulty component can be replaced alone without removing the overall structure or affecting the functions of adjacent modules. This modular design decouples the bearing, adjustment, and adaptation functions of the support, achieving both efficient maintenance of "plug and play" in the high-altitude environment and rapid reconstruction of the guide wheel configuration according to construction requirements, significantly improving the adaptability to complex guide rails and the construction fault tolerance rate.

[0044] In this embodiment, the first seat body 31, the second seat body 32, and the side plate 33 together form a "C"-shaped guide wheel seat 3, which can be adapted to a 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 frame guide wheel 1 is connected in the guide wheel seat 3 through an adjustment mechanism 6. The adjustment mechanism 6 includes an adjustment base 61 and a bearing connection seat 62. The two ends of the adjustment base 61 and the bearing connection seat 62 are connected to each other through an adjustment telescopic rod 63. An adjustment spring 64 is sleeved on the adjustment telescopic rod 63. The bearing connection seat 62 is connected to the adjustable climbing frame guide wheel 1 through a bearing and a rotating shaft 18. The clamping force of the guide wheel is finely adjusted through the adjustment mechanism 6, so that the guide wheel can be closely attached to the surface of the climbing frame guide rail 5, ensuring that the climbing frame guide rail 5 is accurately inserted into the gap and evenly stressed.

[0046] A falling prevention pendulum block 4 is connected to the middle of the support body 2. The falling prevention pendulum block 4 is used to prevent the support from accidentally falling and ensure construction safety.

[0047] Embodiment 3:

[0048] This embodiment provides a multi-modal adjustable climbing frame support. The difference between this embodiment and Embodiment 2 is that the specific style of the guide wheel seat 3 has 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 frame guide wheel 1 and a conical auxiliary wheel 35 are connected to the side seat body 34. The adjustable climbing frame guide wheel 1 is coaxial with the conical auxiliary wheel 35 and abuts against the climbing frame guide rail 5.

[0049] This embodiment makes good use of the modular designed guide wheel seat 3, changes the style of the guide wheel seat 3, and is equipped with an auxiliary wheel 35, which can be adapted to the triangular climbing frame guide rail 5, as shown in Figure 12 .

[0050] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
