Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of scaffolding technology, and in particular to a safety protection device for construction scaffolding. [Background technology]
[0002] Construction scaffolding is a temporary structure used to support workers, materials, and equipment during construction work, and is an important safety measure when working at height.
[0003] A search revealed that a Chinese invention patent with publication number "CN209323951U" discloses a "highly safe protective device for construction engineering scaffolding," which utilizes a design structure in which the sleeve rod can be inserted into the bush, thereby shortening the distance between the vertical rods and reducing the space occupied, making storage and transportation easier. At the same time, a ladder welded to the bush is used, making it easier for construction workers to climb, and improving the safety operating factor for construction workers.
[0004] However, in actual use, the specific shape and protection range of the enclosure included in the device disclosed above cannot be changed, making it difficult to adapt to the protection needs of different construction stages. In particular, in the construction of multi-layer intersection work or special-shaped structures, existing rigid temporary enclosures are prone to creating blind spots for protection and cannot be dynamically adjusted according to changes in working height. Summary of the Invention [Problem to be solved by the invention]
[0005] SUMMARY OF THE INVENTION The object of the present invention is to provide a safety protection device for construction scaffolding to solve the problems presented in the background art above. [Means for solving the problem]
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A safety protection device for a construction scaffold comprises a carrier frame and a storage assembly; The carrier frame has a layout in which the four corners are symmetrical, and one group of storage assemblies and three groups of telescopic assemblies are arranged and fixed at each corner of the upper surface, The storage assembly has a retractable segment reel built in, and the reel is composed of a plurality of independent sub-reel units, each of which has a rotatable hook on its outer surface, and the sub-reel units connect any of the sub-reel units to any of the telescopic assemblies via the hook; After the sub-reel unit is positioned with the telescopic assembly via the hook, the protective temporary enclosure wound inside the sub-reel unit can be deployed along the movement trajectory of the telescopic mechanism, thereby forming a protective temporary enclosure and completing winding protection for the force-receiving plate fixed inside the carrier frame.
[0008] More preferably, the reel comprises: The device comprises a cylindrical body, an assembly rod fixed to the central axis position of the bottom of the inner cylinder, a threaded plug screwed into the opening of the cylindrical body, and a notch on one side of the outer periphery of the cylindrical body that fits into the protective temporary enclosure.
[0009] More preferably, the sub reel unit The inner wall has a sleeve connected to the outer periphery of the assembly rod via a fixed return spring, one side of the protective temporary enclosure is fixed to the outer periphery of the sleeve, and the other side of the protective temporary enclosure passes through the notch and has a connecting plate fixed to it for assembling the hook.
[0010] More preferably, a staircase is fixed to one side of the carrier frame, so that a person can reach the position of the force-receiving plate by walking up the staircase and stand up.
[0011] More preferably, the telescopic assembly comprises a telescopic rod having a hook rod with damping telescopic ability attached thereto, the hook rod having an axial radius smaller than that of the telescopic rod.
[0012] More preferably, the protective fencing is a double-layer nylon mesh fabric with a steel wire mesh lining in the middle, and rubber anti-slip blocks are fixed around the bottom of the carrier frame to ensure that it adheres to the ground. [Effects of the Invention]
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0014] This construction scaffolding safety protection device utilizes a split reel design and an adjustable telescopic assembly in coordination to achieve multi-dimensional extension of the protective temporary enclosure, i.e., the ability to dynamically adjust as the working height changes. In addition, the modular design of the sub-reel unit and the detachable connection structure of the assembly rod ensures convenient equipment maintenance and efficient parts replacement. The protective temporary enclosure, which is made of a composite structure of double-layered nylon mesh cloth and steel wire mesh, ensures light transmission and breathability, while also providing safety protection properties such as impact resistance and puncture resistance. [Brief explanation of the drawings]
[0015] [Figure 1] FIG. 1 is an isometric view of the present invention. [Figure 2] FIG. [Figure 3] 1 is a diagram showing the external structure of the storage assembly of the present invention; [Figure 4] 2 is a cross-sectional view of the internal structure of the storage assembly of the present invention; FIG. DETAILED DESCRIPTION OF THE INVENTION
[0016] The technical solutions in the embodiments of the present invention will be described below clearly and completely with reference to the drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Any other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without requiring creative work will also fall within the scope of protection of the present invention.
[0017] Before understanding the technical solution proposed by this invention, it should be made clear that in the safety protection device for construction scaffolding provided in this embodiment, the carrier frame 1 is formed by welding a high-strength aluminum alloy frame, the storage assemblies 7 symmetrically arranged at the four corners are firmly connected to the telescopic rod 2 by embedded bolts, each storage assembly 7 is equipped with an independently removable reel 701, and the threaded plugs 702 adopt a hexagonal nut structure with a non-slip pattern, which is convenient for quick removal and maintenance by a wrench tool. It should also be added that the application scenario of the technical solution proposed by this invention is specifically for indoor temporary low-floor scaffolding, i.e., scaffolding with a height of 1 to 2 meters, so that the strength of the temporary protective fencing 6 can be appropriately reduced.
[0018] When implemented, the construction worker can pull out the hook rod 3 at the end of the telescopic rod 2 according to the height requirements of the working layer, and then pull out a predetermined length of the protective temporary fencing 6 from the notch 703 of the storage assembly 7. After the hook 704 on the connecting plate engages with the hook rod 3, the sleeve 705 maintains tension balance under the action of the tightening force of the return spring 707, so that the protective temporary fencing 6 forms a three-dimensional protective surface with an adjustable inclination angle vertically. In construction scenes of special-shaped structures, adjacent protective temporary fencing 6 can form a continuous trapezoidal or wavy protective area horizontally by selectively deploying the sub-reel units in different storage assemblies 7.
[0019] In particular, when carrying out multi-level crossing work, the rubber anti-slip blocks on the bottom carrier frame 1 can be fine-tuned in height using adjustment bolts, thereby ensuring stable contact between the equipment and the sloping ground. The pedal surfaces of the staircase 4 are equipped with anti-slip protrusions. The handrail rods of the staircase 4 and the telescopic rod 2 are made of the same standard pipe material, and the entire structure can be removed using a high-speed insertion mechanism. It is also worth noting that the force-receiving plate 5 uses a honeycomb steel plate structure, which deforms when carrying construction workers to distribute the impact load. At the same time, it also forms a mechanical link with the edging strips on the edge of the protective temporary fencing 6, preventing the temporary fencing from being displaced by strong winds.
[0020] Finally, when the device is in the storage state, each sub-reel unit can release the clamping force of the return spring 707 by rotating the threaded plug 702, thereby allowing the protective temporary enclosure 6 to automatically rewind onto the surface of the sleeve 705, at which time the telescopic rod 2 can contract to 1 / 3 of its original length; and it should also be added that the hook rod 3 is attached inside the telescopic rod 2, replacing the original telescopic part inside the telescopic rod 2, and the axial radius of the hook rod 3 is smaller than the axial radius of the telescopic part inside the telescopic rod 2.
[0021] Specifically, as can be seen from Figures 1 to 4, the technical device proposed by the present invention includes: The carrier frame 1 adopts a four-corner symmetrical layout design, with the four corners of the top surface arranged according to functional divisions, with a storage assembly 7 fixedly attached to one corner and telescopic assemblies that can be controlled independently at the remaining three corners. The structure of the carrier frame 1 effectively distributes the carrier load through geometric symmetry, ensuring the mechanical stability of the entire frame.
[0022] In a preferred embodiment, the storage assembly 7 has a built-in modular reel 701. The reel 701 employs a retractable segment design and is composed of six independently removable sub-reel units connected in series vertically. Two rotating hooks 704 are circumferentially equidistantly distributed on the outer surface of each sub-reel unit. The hook groove angle of the rotating hooks 704 matches the shape of the connecting end of the telescopic assembly, allowing any sub-reel unit to be connected to the three telescopic assemblies in multiple directions by rotation.
[0023] In a preferred embodiment, after the hook 704 of the selected sub-reel unit is mechanically locked with the telescopic assembly, the trigger-type transmission device is immediately activated, at which time the protective temporary enclosure 6 inside the sub-reel unit is synchronously deployed along the axial movement trajectory of the telescopic rod 2, maintaining a transmission ratio of 1:1.2 between the deployment speed and the extension speed of the telescopic assembly, ultimately forming a three-dimensional protection system that continuously wraps around the force-receiving plate 5 inside the carrier frame 1.
[0024] In a preferred embodiment, the reel 701 comprises a precision-machined stainless steel cylinder with eight axial guide grooves on its inner wall, an assembly rod 706 welded to the central axis at the bottom of the cylinder, the surface of the rod body being anodized for wear resistance, a threaded plug 702 with higher thread density placed at the opening of the cylinder, and a 32 mm wide trapezoidal opening milled into the side of the cylinder.
[0025] In the preferred embodiment, the core of the sub-reel unit is an aluminum alloy sleeve 705, the inner wall of which is connected to an assembly rod 706 via 12 radially distributed 304 stainless steel return springs 707. A double-helix winding groove is machined on the outer surface of the sleeve 705, and the glass fiber edging of the protective barrier 6 is fixed in the winding groove by a hot melt process, and a polyurethane-coated connecting plate on the opposite side extends and protrudes from the notch 703.
[0026] As a preferred embodiment, in this embodiment, a folding staircase 4 is built into the southeast side of the carrier frame 1. The staircase 4 is constructed by combining aviation aluminum step pedals with a carbon fiber support frame, and the pedal surface is formed with an anti-slip pattern.
[0027] In the preferred embodiment, the telescopic assembly is composed of a high-strength alloy telescopic rod 2 and an improved hook rod 3. The base of the protective fencing 6 is made of a high-strength polyester warp and weft weaving process, and is constructed using a sandwich structure of double-layered 650D nylon mesh fabric and 0.3mm hole diameter 304 stainless steel wire mesh. The edges are double-locked, improving the strength of the protective fencing 6. Marine-grade rubber anti-slip blocks are installed at the four corners of the bottom of the carrier frame 1, and alternating drainage grooves are designed on the bottom of the marine-grade rubber anti-slip blocks.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
