Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and in particular to a foldable movable scaffold. Background Art

[0002] Mobile scaffolding, a widely used construction auxiliary equipment, consists of key components such as diagonal bars, a portal frame, and scaffolding platforms. These components are designed as separate, detachable units for easy transportation and storage. The diagonal bars provide necessary structural stability, the portal frame forms the basic framework, and the scaffolding platforms provide a working platform for construction workers.

[0003] In actual use, after the movable scaffolding components are delivered to the construction site, these individual components need to be reassembled to form a complete and safe scaffolding system. This assembly process not only requires precise measurement and positioning, but also requires strict adherence to a predetermined assembly sequence to ensure the overall stability and safety of the scaffolding. Furthermore, assembling movable scaffolding is often a time-consuming and laborious process. Due to the large number and weight of components and the complex assembly steps, it usually requires the collaboration of at least two workers. This not only increases labor costs but can also lead to low assembly efficiency due to improper operation or lack of coordination, and even affect the safety performance of the scaffolding.

[0004] Therefore, the present application provides a foldable movable scaffold to solve the above problems. Utility Model Content

[0005] The present application provides a foldable movable scaffolding, which aims to solve the problem raised in the background art that the existing scaffolding components are designed as separate, detachable units, and these separate components need to be assembled twice to form a complete and safe scaffolding system. The assembly process is not only time-consuming and labor-intensive, but also requires the collaboration of at least two workers, which increases labor costs.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a foldable movable scaffold comprising two door frame assemblies arranged opposite to each other, a footrest rotatably arranged on one of the door frame assemblies, a ladder assembly fixedly arranged on the other of the door frame assemblies, and a folding structure symmetrically arranged between the two door frame assemblies for driving the two door frame assemblies to move closer or farther relative to each other;

[0007] In order to facilitate the folding and storage of the movable scaffolding of the device: the folding structure includes a movable support fixedly arranged on the top of the door frame assembly, two first hinged rods hinged to each other and hinged to the movable support, a guide frame fixedly arranged at the bottom of the door frame assembly, and two second hinged rods hinged to each other and movably hinged to the guide frame, wherein the middle parts of the first hinged rod and the second hinged rod are hinged by bolt holes. The movable scaffolding can be folded to save storage space. Compared with conventional movable scaffolding, the scaffolding components are not easy to lose when used on the construction site, and each component is connected together. The diagonal rods, door frame, and scaffolding pedals of conventional movable scaffolding are all separate components, and they need to be assembled twice before they can be used after being transported to the construction site. In addition, conventional movable scaffolds often require two people to complete the assembly, while this folding movable scaffolding can be completed by one person.

[0008] Preferably, to facilitate the connection between the second hinged rod and the guide frame, a pin is slidably disposed within the guide frame for liftable movement, and the end of the second hinged rod proximate the guide frame is fitted onto the pin. This pin design ensures a secure and reliable connection between the second hinged rod and the guide frame, preventing the rod from loosening or falling off during use.

[0009] Preferably, the mast assembly includes two opposed mast uprights, and an upper mast crossbar and a lower mast crossbar fixedly disposed between the two mast uprights. When the scaffold is in use, the mast uprights serve as the primary support members, transferring vertical loads to the ground or supporting surface. The upper mast crossbar and the lower mast crossbar provide lateral support, preventing the mast uprights from bending or deforming under load.

[0010] Preferably, to facilitate the scaffolding's attachment to the two mast assemblies during use, one end of the scaffolding is symmetrically fixedly connected to a steel ring that pivots around one of the mast's upper crossbars, while the other end is symmetrically fixedly connected to a curved clip that clips onto the other mast's upper crossbar. This combination of steel ring and curved clip allows for quick and easy installation and removal of the scaffolding, significantly improving work efficiency.

[0011] Preferably, the ladder assembly includes a ladder upright fixedly connected between the upper crossbar of the portal frame and the lower crossbar of the portal frame, and a plurality of ladder crossbars equidistantly fixedly connected between the ladder upright and one of the portal frame uprights. The equidistantly distributed ladder crossbars provide a smooth stepping surface for construction workers, making the climbing process more comfortable and convenient.

[0012] Preferably, in order to facilitate the movement of the scaffold, the bottom ends of the mast uprights are fixedly mounted with moving wheels. The design of the moving wheels enables the scaffold to be easily moved between different construction sites, greatly improving the portability and flexibility of the scaffold.

[0013] Compared to conventional movable scaffolding, this application utilizes a folding structure design that allows for rapid folding and storage, significantly reducing storage space requirements and facilitating flexible on-site deployment and movement. All components are tightly connected, effectively preventing component loss on site and improving construction efficiency and safety. The unique folding mechanism allows the scaffold to be independently erected and folded by one person, reducing labor costs and improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] This embodiment provides a foldable movable scaffold, such as Figure 1-2 As shown, the scaffold comprises two door frame assemblies 1 arranged opposite to each other, a footrest 2 rotatably arranged on one of the door frame assemblies 1, a ladder assembly 3 fixedly arranged on the other door frame assembly 1, and a folding structure 4 symmetrically arranged between the two door frame assemblies 1 for driving the two door frame assemblies 1 to move closer or farther relative to each other;

[0020] In order to facilitate the folding and storage of the movable scaffolding of the device: the folding structure 4 includes a movable support 41 fixedly arranged on the top of the door frame assembly 1, two first hinged rods 42 hinged to each other and hinged to the movable support 41, a guide frame plate 43 fixedly arranged at the bottom of the door frame assembly 1, and two second hinged rods 44 hinged to each other and movably hinged to the guide frame plate 43, wherein the middle parts of the first hinged rod 42 and the second hinged rod 44 are hinged by bolt holes. The movable scaffolding can be folded to save storage space. Compared with conventional movable scaffolding, the scaffolding components are not easy to be lost when used on the construction site, and each component is connected together. The diagonal rods, door frame, and scaffolding pedals 2 of conventional movable scaffolding are all separate components, and they need to be assembled twice before they can be used after being transported to the construction site. In addition, conventional movable scaffolds often require two people to complete the assembly, while this folding movable scaffolding can be completed by one person.

[0021] Folding Process: First, rotate the footrest 2 counterclockwise to the side of the door frame assembly 1 away from the folding structure 4, rotating it from a horizontal position to a vertical position. Next, apply pressure to the adjacent ends of the two door frame assemblies 1, causing the first hinge rod 42 and the second hinge rod 44 to hinge at the bolt holes. As pressure continues to be applied, the bottom of the second hinge rod 44 moves downward along the guide frame 43 until the two door frame assemblies 1 are completely folded together.

[0022] Deployment: Reverse the folding process. First, slightly separate the two folded door frame assemblies 1, allowing the second hinged rod 44 to move upward along the guide frame 43. Next, adjust the hinge angles of the first hinged rod 42 and the second hinged rod 44 to gradually unfold the two door frame assemblies 1 to the desired operating position. Finally, rotate the footrest 2 from the vertical position back to the horizontal position to begin use.

[0023] Specifically, to facilitate the connection between the second hinged rod 44 and the guide frame 43, a pin 431 is slidably disposed within the guide frame 43, allowing for liftable movement. The end of the second hinged rod 44 closest to the guide frame 43 is mounted on the pin 431. The design of the pin 431 ensures a secure and reliable connection between the second hinged rod 44 and the guide frame 43, preventing it from loosening or falling off during use. The design of the pin 431 also provides a degree of adaptability between the second hinged rod 44 and the guide frame 43, enabling it to accommodate folding requirements at various angles and positions, ensuring the stability and smoothness of the scaffold during folding and unfolding.

[0024] Specifically, the portal frame assembly 1 includes two portal frame uprights 11 arranged opposite to each other, and an upper portal frame crossbar 12 and a lower portal frame crossbar 13 fixedly arranged between the two portal frame uprights 11. When the scaffolding is in use, the portal frame uprights 11 serve as the main supporting components, transferring the vertical load to the ground or supporting surface. The upper portal frame crossbar 12 and the lower portal frame crossbar 13 play a lateral supporting role, preventing the portal frame uprights 11 from bending or deforming when subjected to force. During the folding and unfolding process of the folding movable scaffolding, the components of the portal frame assembly 1 are relatively moved and fixed through the folding structure 4 to ensure the stability and safety of the scaffolding.

[0025] Specifically, to facilitate the use of the scaffolding 2, it is fixed to the two door frame assemblies 1: one end of the scaffolding 2 is symmetrically fixedly connected to a steel ring 21 that is rotatably mounted on one of the upper crossbars 12 of the door frame, and the other end of the scaffolding 2 is symmetrically fixedly connected to a curved clip 22 that is clipped to the other upper crossbar 12 of the door frame. The combination of the steel ring 21 and the curved clip 22 allows users to easily and quickly install and remove the scaffolding 2, greatly improving work efficiency. The steel ring 21 allows the scaffolding 2 to rotate freely within a certain range, allowing users to adjust its angle and position according to actual needs, enhancing the flexibility and adaptability of the scaffolding.

[0026] Installation process: First, rotate the steel ring 21 at one end of the scaffolding 2 and fit it onto one of the upper crossbars 12 of the mast. Then, lift the other end of the scaffolding 2 so that the curved clip 22 is aligned with the other upper crossbar 12 of the mast. Finally, gently push the scaffolding 2 so that the curved clip 22 elastically engages with the upper crossbar 12 of the mast, completing the installation.

[0027] Disassembly process: First, gently press the arc-shaped clamping plate 22 by hand to separate it from the upper crossbar 12 of the mast. Then, rotate the scaffolding 2 counterclockwise to rotate the steel ring 21 on it around the upper crossbar 12 of the mast until the scaffolding 2 rotates from a horizontal state to a vertical state.

[0028] Specifically, the ladder assembly 3 includes a ladder upright 31 fixedly connected between the upper mast crossbar 12 and the lower mast crossbar 13, and a plurality of ladder crossbars 32 equidistantly fixedly connected between the ladder upright 31 and one of the mast uprights 11. The evenly spaced ladder crossbars 32 provide a smooth stepping surface for construction workers, making the climbing process more comfortable and convenient. Construction workers step on the ladder crossbars 32 to gradually ascend to the desired working height. The evenly spaced and secure connection of the ladder crossbars 32 ensures a smooth and comfortable climbing process.

[0029] Specifically, to facilitate the movement of the scaffold, wheels 5 are fixedly mounted at the bottom ends of the mast uprights 11. These wheels allow the scaffold to be easily moved between construction sites, significantly enhancing its portability and flexibility. By installing wheels 5, users can more easily carry and move the scaffold, reducing labor intensity and improving work efficiency.

[0030] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
