Technical Field
[0001] This invention relates to the field of construction safety technology, and in particular to an adjustable protective device for disc-lock scaffolding. Background Technology
[0002] In construction, modular scaffolding is widely used due to its structural stability and ease of assembly and disassembly. To meet the needs of personnel and material passage, safety passage openings are often set at the bottom of the scaffolding. Horizontal protection above these openings is crucial, directly affecting the safety of personnel passing below. Currently, common protective measures mainly include laying steel mesh, bamboo planks, wooden boards, or other temporary materials.
[0003] However, these traditional protective methods have many drawbacks: First, steel mesh typically has large openings and is not tightly sealed, posing a risk of small falling objects. Furthermore, it is prone to deformation after repeated use, affecting the protective effect and installation flatness. Second, materials such as bamboo planks and wooden boards lack effective standardized fixing measures and are usually simply placed on the ground, making it difficult to guarantee their installation strength. They are prone to displacement or falling under strong winds or accidental impacts, resulting in low reliability. Third, none of the above methods are dedicated facilities for use with modular scaffolding. The installation process is cumbersome, and the protective dimensions are difficult to match the actual width of the passageway, easily leading to insufficient protection or material waste. The overall appearance is also cluttered, failing to meet the requirements of standardized safety management at construction sites. In addition, these temporary protective materials suffer high turnover losses and low reuse rates, increasing construction costs.
[0004] Therefore, there is an urgent need for a specialized horizontal protection device that can be standardized and compatible with disc-lock scaffolding, is quick to install, provides reliable protection, has adjustable width, and can be reused repeatedly, so as to fundamentally solve the protection problem above the safety passage opening. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to provide an adjustable protective device for disc-lock scaffolding, which can achieve standardized and rapid connection with disc-lock scaffolding and can flexibly adjust the protective range according to the actual width of the passage. It has the advantages of stable structure, convenient installation, reusability, and high safety and reliability.
[0006] The adjustable protective device for disc-lock scaffolding of the present invention includes a main protective plate, a left auxiliary protective plate and a right auxiliary protective plate respectively disposed on both sides of the main protective plate, and an adjustment component for driving the left auxiliary protective plate and the right auxiliary protective plate to slide towards or away from each other; the auxiliary protective plates slide in cooperation with the main protective plate to adjust the overall protective width.
[0007] Furthermore, the main protective plate is provided with a slide rail, and the left auxiliary protective plate and the right auxiliary protective plate are respectively provided with matching slide rails that cooperate with the slide rail. The left auxiliary protective plate and the right auxiliary protective plate slide in cooperation with the slide rail of the main protective plate through their matching slide rails.
[0008] Furthermore, the main protective plate is also provided with a fixing plate for installing the adjustment component, and the auxiliary protective plate is provided with a driving plate that cooperates with the adjustment component for driving.
[0009] Furthermore, the adjustment assembly includes two operating screws, which are used to drive the left auxiliary protective plate and the right auxiliary protective plate respectively; one end of each operating screw is rotatably engaged with the fixed plate with a single degree of freedom, and the other end is threadedly engaged with the drive plate of the corresponding auxiliary protective plate, so that the corresponding auxiliary protective plate can be driven to slide by rotating the operating screw.
[0010] Furthermore, one end of the operating screw is provided with a handle and / or a handle dial.
[0011] Furthermore, it also includes a connecting bolt assembly, which is disposed in a reserved hole at the edge of the main protective plate, for detachably connecting the protective device to the horizontal bar disc-lock node of the disc-lock scaffold.
[0012] Furthermore, the connecting bolt assembly includes a screw main rod and a rotatable fixing member disposed at one end thereon. The rotatable fixing member is capable of rotating after it passes through the scaffolding disc buckle along with the screw main rod, for the purpose of achieving initial fixing.
[0013] Furthermore, the rotatable fixing component is also equipped with an anti-tamper alarm device, which includes an angle sensor and a control unit. When the angle sensor detects that the rotatable fixing component has rotated more than a set angle relative to the initial fixing position, the control unit triggers an alarm.
[0014] Furthermore, the connecting bolt assembly also includes fastening bolts for final tightening after the rotatable fixing member has been initially fixed.
[0015] The beneficial effects of this invention are as follows: The adjustable protective device for disc-lock scaffolding of this invention, through the setting of a sliding-fitting main protective plate and an auxiliary protective plate, and equipped with dedicated adjustment and connection components, achieves flexible and precise adjustment of the protective width, perfectly adapting to safety passage openings of different sizes. Its standardized design allows for quick and stable connection with disc-lock nodes, facilitating installation and disassembly, and significantly improving construction efficiency and the standardization level of the scaffolding. The device has a robust structure and provides comprehensive protection, significantly reducing the risk of falling objects from heights and ensuring safe passage. Furthermore, its main body is made of steel, making it highly durable and reusable multiple times, effectively reducing the consumption and waste of traditional temporary protective materials, resulting in significant economic benefits and broad application prospects.

[0026] It should be noted that in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.
[0027] As shown in the figure: This embodiment provides an adjustable protective device for disc-lock scaffolding, including a main protective plate 1, a left auxiliary protective plate 2 and a right auxiliary protective plate 3 symmetrically arranged on the left and right sides of the main protective plate 1, and an adjustment component for driving the two auxiliary protective plates to slide in opposite directions or back directions along the main protective plate 1; the auxiliary protective plates achieve positional changes in the length direction of the main protective plate 1 through a sliding fit with the main protective plate 1, thereby flexibly and continuously adjusting the overall protective width of the entire protective device according to the actual width of the safety passage opening on site, ensuring that the protective coverage can adapt to different engineering needs; at the same time, the main protective plate 1, the left auxiliary protective plate 2 and the right auxiliary protective plate 3 are made of steel, which is durable and can be reused multiple times, effectively reducing the consumption and waste of traditional temporary protective materials, and has significant economic benefits and broad application prospects.
[0028] In this embodiment, the main protective plate 1 is provided with longitudinally extending slide rails 1a on both sides of its length direction; correspondingly, the inner sides of the left auxiliary protective plate 2 and the right auxiliary protective plate 3 are respectively provided with matching slide rails 4 that match the shape and size of the slide rails 1a. By precisely nesting the matching slide rails 4 of the auxiliary protective plate into the slide rails 1a of the main protective plate 1, the two form a stable sliding pair connection. This cooperation between the slide rails 1a and the matching slide rails 4 not only ensures the smoothness and stability of the auxiliary protective plate during the sliding process and effectively prevents it from overturning or derailing when under force, but also ensures that the auxiliary protective plate can remain in the same protective plane as the main protective plate 1 after it extends, thus maintaining the flatness and uniformity of the overall structure.
[0029] In this embodiment, for the installation and driving of the adjustment component, a fixing plate 1b for installing the adjustment component is fixedly provided in the middle region of the main protective plate 1 (e.g., along its center line in the width direction); at the same time, a driving plate 5 is provided at the inner end of the left auxiliary protective plate 2 and the right auxiliary protective plate 3 (i.e., the end closer to the main protective plate 1), and the driving plate 5 is machined with an internal thread hole for forming a transmission connection with the adjustment component; the arrangement of the fixing plate 1b and the driving plate 5 provides a reliable transmission fulcrum and application point for the adjustment force.
[0030] In this embodiment, the adjustment assembly includes two independently operating screws 6, which are used to drive the left auxiliary protective plate 2 and the right auxiliary protective plate 3, respectively. One end (e.g., the tail end) of each operating screw 6 is connected to the fixed plate 1b on the main protective plate 1 through a bearing, bushing or other single-degree-of-freedom rotating pair structure, so that it can rotate freely relative to the fixed plate 1b but is axially constrained. The other end (i.e., the screw section) of the operating screw 6 is screwed into the internal threaded hole of the corresponding auxiliary protective plate drive plate 5 to form a threaded transmission pair. When the operating screw 6 is rotated by a tool or manually, due to the axial constraint between the screw and the fixed plate 1b and the threaded engagement between the screw and the drive plate 5, the rotational motion will be converted into linear displacement of the drive plate 5 and its corresponding auxiliary protective plate along the slide rail 1a, thereby realizing precise and independent adjustment of the position of the two protective plates.
[0031] Meanwhile, to facilitate manual operation by construction personnel and improve the ease of adjustment, each operating screw 6 can be equipped with a handle 6b and / or a handle turntable 6a at its tail end (located outside the fixed plate 1b). The handle 6b and / or the handle turntable 6a provide a good gripping point, allowing the operator to perform rotational adjustment effortlessly without the need for special tools. This is particularly suitable for use in high-altitude scaffolding environments, enhancing the device's on-site applicability and operational efficiency.
[0032] In this embodiment, in order to achieve a reliable connection between the protective device and the main body of the scaffold, the device also includes a dedicated connecting bolt assembly. The connecting bolt assembly is usually set in the reserved holes 1c at the four corners or other key stress positions of the main protective plate 1. Its function is to firmly and detachably connect the entire protective device to the disc buckle node of the disc buckle scaffold horizontal bar. Through this modular connection method, the device can be quickly installed and disassembled, and is convenient for reuse.
[0033] In this embodiment, the connecting bolt assembly includes a screw main rod 7 and a rotatable fixing component 8 (such as a wedge, baffle, or foldable claw) disposed at one end of the screw main rod 7. During installation, after the screw main rod 7 is passed through the reserved hole 1c of the main protective plate 1 and the hole of the scaffolding buckle 11 in sequence, the rotatable fixing component 8 can rotate relative to the screw main rod 7 by an angle (e.g., 90 degrees) through a structure such as a rotating shaft 9, so that it is locked on the back of the buckle, thereby forming a preliminary hook or limiting fixation, preventing the device from falling off before subsequent tightening, which greatly facilitates high-altitude single-person installation operations.
[0034] In this embodiment, to further improve the safety management level of the protective device and prevent unauthorized disassembly or failure due to loosening caused by vibration or other reasons, the rotatable fixing component 8 is also integrated with an anti-dismantling alarm device. The anti-dismantling alarm device mainly consists of an angle sensor and a control unit. The angle sensor monitors the rotation angle change of the rotatable fixing component 8 relative to its initial fixed position (i.e., the position used to hold the back of the disc buckle after installation) in real time. The control unit continuously receives the monitoring data from the angle sensor. When the control unit detects that the rotatable fixing component 8 has rotated and the rotation angle exceeds the preset safety threshold (e.g., exceeding 10° to 15°), the control unit will determine that there is an illegal disassembly attempt or that the connecting bolt assembly is loose, and immediately trigger an alarm. The alarm is externally linked to the smart construction site safety management system to form a linkage control.
[0035] In this embodiment, to ensure the final stability of the connection, the connecting bolt assembly also includes a fastening bolt 10. After the rotatable fixing component 8 is initially fixed and the device position is leveled, the fastening bolt 10 is tightened on the threaded section of the screw main rod 7, so that the main protective plate 1 is tightly attached to the surface of the scaffolding disc buckle 11. The gap is eliminated by the bolt preload, forming a rigid connection that is resistant to shear and tension, thereby withstanding possible impact loads and vibrations during long-term use, ensuring the absolute stability of the protective device under any working condition.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
