Description

Technical Field

[0001] This invention relates to the field of disc-lock scaffolding technology, specifically to a disc-lock scaffolding and its processing method. Background Technology

[0002] Disc-lock scaffolding is a widely used support platform in construction, engineering maintenance, and other scenarios. It is composed of multiple poles connected by a disc-lock structure, and features convenient assembly and strong load-bearing capacity. It mainly consists of uprights, horizontal bars, disc-lock joints, and matching protective and support components. The overall frame is assembled by snapping and locking the uprights and horizontal bars, providing a stable operating foundation for high-altitude operations.

[0003] The "Multifunctional Scaffold for Tunnel Maintenance" disclosed in application number "CN107829551B" is a relatively mature technology currently used in the industry. It includes four support platforms, each with casters underneath. A balancing mechanism connects the support platforms, and this mechanism comprises an electric telescopic rod, a fixed column, a connecting cylinder, a threaded hole, a threaded rod, a fixed tightening block, a level, a nut, a fixed bearing, a connecting shaft, an electromagnet, a heightening mechanism, and a stabilizing mechanism. The heightening mechanism includes a sleeve, a fixed rod, a climbing ladder, a telescopic connecting rod, a foldable foot pedal, a connecting rod, a protective mechanism, and a toolbox mechanism. The stabilizing mechanism includes an electric telescopic rod, a vacuum suction cup, a fixed frame, a small bearing, a rotating shaft, a support column, an extension mechanism, support legs, and an anti-slip pad. A control mechanism is located on each support platform, comprising a rechargeable battery, a controller, a power connector, a signal receiver, a PLC system, and a remote control. The advantages of this invention are its simple structure and strong practicality.

[0004] However, the aforementioned high-strength disc-lock scaffold design has the following drawbacks: the scaffold only improves structural strength by thickening the walls of the rods and adding reinforcing ribs to the connecting seats. The diagonal bracing is only a single diagonal connection. This structural design does not adequately consider the protection against tilting and overturning. When the ground is uneven, the working load is unbalanced, or the scaffold is subjected to external impact, it is prone to overall tilting or even overturning. At the same time, the moving and fixed structures of this disc-lock scaffold are separated. The moving rollers only have a simple braking function and cannot effectively transfer the load. The support stability is poor when fixed. Moreover, the connection between each frame layer relies only on a single disc-lock snap-fit ​​without a multiple locking structure. After long-term use, the connection is prone to loosening, which leads to a decrease in the structural stability of the scaffold and seriously affects the safety of high-altitude operations. It cannot meet the needs of complex construction scenarios.

[0005] Therefore, it is necessary to provide a disc-lock scaffold and a processing method to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a disc-lock scaffold and its processing method, solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a disc-lock scaffold, comprising a lower frame, characterized in that anti-tilting mechanisms are provided on both sides of the lower frame, a middle frame is provided at the top of the lower frame, a disc-lock fixing mechanism is provided on the side of the middle frame, an upper frame is provided at the top of the middle frame, and a fixing mechanism is provided on the side of the upper frame.

[0008] Preferably, the anti-tilt mechanism includes several fasteners symmetrically arranged at both ends of the lower frame. Scaffolding flooring is fixedly connected to the inner sides of the fasteners. A connecting plate is movably connected to the side of the lower frame. The other end of the connecting plate is movably connected to a support column. A threaded fixing column is provided at the bottom of the support column. A movable roller is threadedly connected to the bottom of the threaded fixing column. A brake is installed on one side of the movable roller. A scaffolding fixing column is fixedly connected to the top of the threaded fixing column. A fastening element is installed on one side of both the scaffolding fixing column and the threaded fixing column. A clamping groove is provided on one side of the fastening element. A threaded rod is movably connected to the other side of the fastening element. A nut is threadedly connected to the outer side of the threaded rod.

[0009] Preferably, the disc buckle fixing mechanism includes through rods fixedly connected to the top four sides of the middle frame, a connecting frame inserted into the top of the through rods, and combined fixing components provided at the top four corners of the connecting frame. The combined fixing component includes a transverse column on one side of the connecting frame, a longitudinal column on the other side of the transverse column, a locking member on the outer side of the transverse column and the longitudinal column, a fastening member on one side of the locking member, a bolt rod movably mounted on one side of the fastening member, a fixing slot on one side of the locking member, and one end of the bolt rod being threadedly fixed to the fixing slot.

[0010] Preferably, the fixing mechanism includes a scaffold top frame that is fixedly connected to the top of the upper frame by screws, and tie rods are arranged crosswise on both sides of the scaffold top frame. The two ends of the tie rods are movably connected to the scaffold top frame, and a fixed handle is fixedly connected to the inner side of the scaffold top frame.

[0011] A method for manufacturing a disc-lock scaffold includes the following steps: Step 1: Machining of the anti-tilt mechanism; Step 2: Processing and assembly of the disc buckle fixing mechanism; Step 3: Processing and assembly of the upper frame and fixing mechanism.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a disc-lock scaffold and its processing method: 1) By setting an integrated anti-tilting mechanism on both sides of the lower frame, and using the connecting plate and the support column to form an angle-adjustable inclined support structure, combined with the ground bearing design of the scaffold fixed column, the support angle can be flexibly adjusted according to the flatness of the construction site ground, so that the support column and the lower frame form a triangular stable structure, effectively distributing the working load to the ground. This solves the problem of insufficient protection of the existing scaffold single diagonal brace and easy tilting when the ground is uneven. It eliminates the risk of overturning from the foundation layer. At the same time, the locking groove and threaded rod locking structure of the fastener can firmly connect the support column to the main frame, further strengthening the rigidity of the inclined support and ensuring the stability of the overall structure when there is external force collision or load offset.

[0013] 2) The disc buckle fixing mechanism set on the side of the middle frame achieves initial positioning by inserting the rod and connecting frame. Then, the intersecting positions of the horizontal and vertical rods are firmly fixed by the locking parts, fastening parts and threaded locking of the bolt rods of the combined fixing components. This achieves multi-directional and rapid locking of the middle frame with the upper and lower frames and external rods. Compared with the existing single disc buckle snap-fit ​​structure, it adds a dual connection method of sleeve and threaded locking, which effectively avoids the problem of loosening after long-term use and improves the reliability of multi-layer frame connection. At the same time, the adjustable design of the combined fixing components can adapt to the connection of rods of different specifications, making it more versatile.

[0014] 3) The upper frame's fixing mechanism adopts a design of scaffold top frame and cross tie rods. The movable connection between the tie rods and the top frame can effectively absorb and disperse vibration and impact loads from different directions, avoid structural fatigue damage caused by stress concentration, and significantly improve the top structure's resistance to lateral forces and torsion. The fixed handles on the inside of the top frame provide reliable leverage points for operators. Combined with the anti-slip design, it makes the assembly, disassembly, and high-altitude operation of the scaffold more convenient, further reducing operational safety hazards.

Therefore, they should not be construed as limitations on this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "configuration" should be interpreted broadly. For example, they can refer to a fixed connection or configuration, a detachable connection or configuration, or an integral connection or configuration. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1-8 As shown, the present invention proposes a disc buckle scaffold, including a lower frame 1, anti-tilting mechanisms 2 on both sides of the lower frame 1, a middle frame 3 on the top of the lower frame 1, a disc buckle fixing mechanism 4 on the side of the middle frame 3, an upper frame 5 on the top of the middle frame 3, and a fixing mechanism 6 on the side of the upper frame 5.

[0022] To increase the working area and accommodate operating platforms of varying heights, a middle frame 3 is installed at the top of the lower frame 1, and an upper frame 5 is installed at the top of the middle frame 3. To ensure a stable connection, the sides of the middle frame 3 are equipped with disc-locking mechanisms 4 for connecting to uprights or horizontal bars, and the sides of the upper frame 5 are equipped with fixing mechanisms 6 for securing guardrails or other accessories. To prevent the scaffolding from tipping over during use, anti-tilting mechanisms 2 are installed on both sides of the lower frame 1. The anti-tilt mechanism 2 includes several fasteners 201 symmetrically arranged at both ends of the lower frame 1. Scaffolding floor 202 is fixedly connected to the inner sides of the fasteners 201. A connecting plate 203 is movably connected to the side of the lower frame 1. The other end of the connecting plate 203 is movably connected to a support column 204. A threaded fixing column 205 is provided at the bottom end of the support column 204. A movable roller 206 is threadedly connected to the bottom end of the threaded fixing column 205. A brake 207 is installed on one side of the movable roller 206. A scaffolding fixing column 208 is fixedly connected to the top of the threaded fixing column 205. A fastening element 209 is installed on one side of the scaffolding fixing column 208 and the threaded fixing column 205. A clamping groove 2010 is provided on one side of the fastening element 209. A threaded rod 2011 is movably connected to the other side of the fastening element 209. A nut 2012 is threadedly connected to the outer side of the threaded rod 2011.

[0023] The scaffolding floor 202 is fixedly connected to the inner side of the fastener 201, providing a stable and safe walking and working surface for operators. To provide diagonal support for the entire scaffolding and prevent lateral tilting, a connecting plate 203 is movably connected to the side of the lower frame 1. The connecting plate 203 acts as a connector, with its other end movably connected to the support column 204. This movable connection, similar to a hinge, allows the support column 204 to adjust its support angle according to ground conditions. To facilitate the movement of the entire scaffolding on the construction site, the bottom end of the threaded fixed column 205 is threadedly connected to a movable roller 206. The connection allows for fine-tuning of the roller height. When a fixed position is required, a brake 207 is installed on one side of the movable roller 206. Stepping on the brake 207 locks the roller and prevents it from rolling. After the scaffolding moves to the predetermined position, in order to improve the stability and grip of the support, it is necessary to unload the movable roller 206 or transfer the support force to the ground. For this purpose, a scaffolding fixing column 208 is fixedly connected to the top of the threaded fixing column 205. By rotating the threaded fixing column 205, the distance between the scaffolding fixing column 208 and the ground can be adjusted so that it contacts the ground and bears the load, thus sharing the pressure of the movable roller 206. To further enhance the connection rigidity between the support column 204 and the lower frame 1 or other uprights, a fastening element 209 is installed on one side of the scaffold fixing column 208 and the threaded fixing column 205. Specifically, a clamping groove 2010 is provided on one side of the fastening element 209. The clamping groove 2010 is used to clamp the scaffold uprights or horizontal bars to achieve quick positioning. A threaded rod 2011 is movably connected to the other side of the fastening element 209. A nut 2012 is threadedly connected to the outer side of the threaded rod 2011. During installation, the clamping groove 2010 of the fastening element 209 is aligned with the steel pipe to be fixed. Then, by tightening the nut 2012, the threaded rod 2011 drives the fastening element 209 to tighten, thereby firmly fixing it to the scaffold.

[0024] When assembling the disc-lock scaffold, firstly, the lower frame 1 is moved to the construction point using the moving rollers 206, and the brake 207 is depressed for initial positioning. Then, depending on the flatness of the ground, the threaded fixing column 205 is rotated to ensure that the scaffold fixing column 208 is stably supported on the ground. Next, the scaffold floor 202 is laid using the snap fasteners 201. Subsequently, the middle frame 3 and the upper frame 5 are erected sequentially on the lower frame 1, and the connecting nodes are locked using the disc-lock fixing mechanism 4 and the fixing mechanism 6 to ensure the stability of the overall structure. Finally, the anti-tilting mechanism 2 is deployed on both sides as needed, the angle of the connecting plate 203 and the support column 204 is adjusted, and they are locked to the main frame using the fasteners 209 to form a triangular stable structure, effectively preventing the scaffold from tilting during operation.

[0025] The disc buckle fixing mechanism 4 includes through rods 401 fixedly connected to the top four sides of the middle frame 3, a connecting frame 402 through the top of the through rods 401, and a combination fixing component 403 at the top four corners of the connecting frame 402. The combined fixing assembly 403 includes a transverse column 404 on one side of the connecting frame 402, a longitudinal column 405 on the other side of the transverse column 404, a locking member 406 on the outer side of the transverse column 404 and the longitudinal column 405, a fastening member 407 on one side of the locking member 406, a bolt rod 408 movably disposed on one side of the locking member 406, a fixing slot 409 on one side of the locking member 406, and one end of the bolt rod 408 being threadedly fixedly connected to the fixing slot 409.

[0026] Four through rods 401 are provided, which are fixedly connected to the four sides of the top of the middle frame 3 respectively, for supporting and connecting the structure above. Each through rod 401 has a connecting frame 402 inserted at the top. The connecting frame 402 has a rectangular frame structure, and its bottom is sleeved with the through rod 401 to achieve initial positioning. At the four corners of the top of the connecting frame 402, there are combination fixing components 403, which are used to further lock and fix the connection between the connecting frame 402 and the upper component or adjacent frame. The combination fixing components 403 include transverse rods 404, longitudinal rods 405, locking parts 406, fastening parts 407 and bolt rods 408. In each combination fixing component 403, the transverse rods 404 are set on one side of the connecting frame 402, while the longitudinal rods 405 are set on the other side of the transverse rods 404. The two are arranged perpendicularly to each other to form a positioning base similar to an "L".

[0027] Engaging members 406 are sleeved on the outer sides of the transverse column 404 and the longitudinal column 405. The engaging member 406 is a block-shaped structure with two positive traffic channels, which slides or engages with the transverse column 404 and the longitudinal column 405 respectively, allowing for position adjustment along the columns. A fastening member 407 is provided on one side of the engaging member 406. The fastening member 407 is a movable clamping component used to fasten with adjacent connectors or frame corners. A bolt rod 408 is movably mounted on one side of the fastening member 407, and the bolt rod 408 can be engaged relative to the fastening member. The component 407 rotates and moves. At the same time, a fixing slot 409 is provided on the corresponding side of the engaging component 406. The fixing slot 409 is a threaded hole structure. After the positions of the engaging component 406 and the fastening component 407 are adjusted, the bolt rod 408 is rotated so that one end is screwed into the fixing slot 409 and threaded to fix it, thereby locking the fastening component 407 and the engaging component 406. This makes the entire combined fixing assembly 403 firmly fix the relative positions of the transverse column 404 and the longitudinal column 405, and realize the reliable connection between the connecting frame 402 and the external frame.

[0028] The fixing mechanism 6 includes a scaffold top frame 601 that is fixedly connected to the top of the upper frame 5 by screws. Tie rods 602 are arranged crosswise on both sides of the scaffold top frame 601. The two ends of the tie rods 602 are movably connected to the scaffold top frame 601. A fixed handle 603 is fixedly connected to the inner side of the scaffold top frame 601.

[0029] To enhance the lateral force resistance and structural rigidity of the entire fixed mechanism 6, tie rods 602 are cross-connected on both sides of the scaffold top frame 601. The tie rods 602 are arranged in an "X" shape or similar cross layout. The two ends of the tie rods 602 are not fixedly welded, but are movably connected to the corresponding connection points of the scaffold top frame 601, such as through pins, bolts or hinge seats. The movable connection method allows the tie rods 602 to have a certain degree of fine adjustment capability during installation and use, which can effectively absorb and disperse vibration and impact loads from different directions, prevent structural fatigue damage caused by stress concentration, and enhance the overall torsional and lateral tilt resistance of the scaffold top frame 601. In addition, to facilitate the gripping and force application by operators during assembly, hoisting or disassembly, a fixed handle 603 is fixedly connected to the inner side of the scaffold top frame 601. The fixed handle 603 is usually made of bent or welded metal pipe, and the surface can be knurled or fitted with rubber anti-slip sleeves to increase friction. When operators are working at height or adjusting the position of the fixed mechanism, they can obtain a reliable point of force by holding the fixed handle 603, thereby improving the safety and convenience of operation.

[0030] A method for manufacturing a disc-lock scaffold includes the following steps: Step 1: Machining of the anti-tilt mechanism In the processing of disc-lock scaffolding, the lower frame 1 and its anti-tilting mechanism 2 need to be processed and pre-assembled first. As the load-bearing foundation of the entire scaffolding, the structural strength and stability of the lower frame 1 directly affect the safety and reliability of the subsequent construction. Therefore, the material selection and welding process must be strictly controlled during the processing to ensure the geometric accuracy and connection strength of the frame. The lower frame 1 is generally made of high-strength steel pipes and is rectangular or square in shape. It has connecting ear plates or plug interfaces at the four corners for connecting with the middle frame 3 and the anti-tilt mechanism 2. During processing, the steel pipes of the corresponding length are first cut according to the design drawings and positioned by tooling fixtures to ensure that the length of each side is consistent and the diagonal error is controlled within the allowable range. Then, carbon dioxide gas shielded welding or argon arc welding is used for welding. The weld should be uniform, without slag inclusions or porosity. After welding, stress relief treatment is performed to prevent deformation in the later stage. Fasteners 201 are typically manufactured using stamping or casting processes, and their surfaces are galvanized or spray-coated to improve corrosion resistance. Scaffold flooring 202 is made of anti-slip steel or aluminum alloy, with reinforced edges and welded reinforcing ribs on the back to ensure load-bearing capacity. Hinged holes need to be machined at the connection between the connecting plate 203 and the support column 204 to facilitate subsequent angle adjustment. The threaded part of the threaded fixing column 205 needs to be machined to ensure the fitting accuracy with the moving roller 206 and the nut 2012. The moving roller 206 is a universal wheel or a fixed wheel. The wheel body material is polyurethane or rubber, which has wear resistance and shock absorption performance. The brake component 207 adopts a foot pedal braking structure, and a flexibility test needs to be performed before assembly. During the pre-assembly stage, the lower frame 1 is placed on a horizontal platform, and the fasteners 201 and scaffold floor 202 are installed in sequence to ensure that the floor is flat and without warping. Then, one end of the connecting plate 203 is hinged to the lower frame 1, and the other end is hinged to the support column 204. The bottom of the support column 204 is fitted with a threaded fixing column 205 and a moving roller 206. Finally, the fasteners 209 are installed, and the position of the locking groove 2010 is adjusted to ensure that it can fit tightly with the upright. The entire pre-assembly process requires repeated checks on the flexibility of each moving part and the reliability of the locking mechanism to ensure that the anti-tilt mechanism 2 can be quickly deployed and stably supported in actual use.

[0031] Step Two: Processing and Assembly of the Disc Buckle Fixing Mechanism The middle frame 3 is the core load-bearing layer of the disc-lock scaffolding. Its main function is to connect the lower frame 1 and the upper frame 5, and to achieve rapid locking of multi-directional members through the disc-lock fixing mechanism 4. The middle frame 3 is also made of high-strength steel pipe welded together. The structural form is usually a rectangular frame with disc-lock connecting seats at the four corners for easy connection with the uprights or crossbars. During the processing, the sides of the middle frame 3 are first cut and prepared to ensure accurate dimensions. Then, they are assembled and welded. Special tooling is used to fix them during welding to prevent deformation. After welding, grinding and flaw detection are carried out to ensure that the weld quality meets national standards. The four sides of the top of the middle frame 3 need to be pre-embedded or welded with through rods 401. The through rods 401 are cylindrical steel pipes with smooth surfaces, which are easy to fit with the connecting frame 402. The fabrication of the disc buckle fixing mechanism 4 includes the production of components such as the insert rod 401, connecting frame 402, combined fixing assembly 403, transverse rod 404, longitudinal rod 405, snap-fit ​​component 406, fastener component 407, and bolt rod 408. The insert rod 401 is made of seamless steel pipe with chamfered ends for easy insertion into the connecting frame 402. The connecting frame 402 is a rectangular frame structure with a corresponding socket hole at the bottom for the insert rod 401. A nylon bushing can be installed in the hole to reduce wear. The combined fixing component 403 is the core part of the disc buckle fixing mechanism 4. Its machining accuracy directly affects the locking effect. The transverse rod 404 and the longitudinal rod 405 are made of precision cold-drawn steel tubes with chrome plating or anti-rust paint spraying. The locking part 406 is a precision cast steel part with a positive passage hole inside and a guide groove machined in the hole to facilitate cooperation with the rod. The fastening part 407 is a movable clamping structure, which is connected to the locking part 406 through a pin, allowing for flexible movement. During the assembly stage, the connecting frame 402 is first fitted onto the insert rod 401 and temporarily fixed after being adjusted to a suitable height. Then, the combined fixing components 403 are installed at the four corners of the connecting frame 402. The transverse rod 404 and the longitudinal rod 405 are respectively inserted into the positive communication holes of the snap-fit ​​component 406. After adjusting the position, the fastener 407 is placed in. Finally, the bolt rod 408 is passed through the fastener 407 and screwed into the fixing slot 409 to lock the entire component. After the assembly is completed, a locking force test is required to ensure that it will not loosen under stress.

[0032] Step 3: Processing and assembly of the upper frame and fixing mechanism The upper frame 5 is the top structure of the disc-lock scaffold, mainly used to support operators and construction materials. It is also the main installation base of the fixing mechanism 6. The processing technology of the upper frame 5 is similar to that of the middle frame 3, but the structure adds interfaces for connecting with the fixing mechanism 6, such as screw holes and hinge seats. The upper frame 5 is welded from rectangular steel pipes, with reinforcing plates at the four corners. The top is pre-drilled with threaded holes or through holes for connection with the scaffold top frame 601. After welding, the frame is leveled to ensure that the flatness error of the frame is less than 2mm. The scaffold top frame 601 is an independent component, made of steel plate bending or steel section welding, with anti-rust paint sprayed on the surface. The top frame has hinge holes on both sides for installing tie rods 602. The tie rod 602 is made of round steel or square tube, with connecting ear plates machined at both ends. The ear plates have high precision requirements for opening and need to be used in conjunction with the hinge holes on the top frame. The tie rod 602 is arranged in an X-shape and is connected to the top frame by a pin during installation to ensure that it has a certain degree of swing freedom to adapt to different force directions. The fixed grip 603 is made of a round tube bent into shape, with both ends welded or threaded to the inside of the top frame. The surface is knurled or covered with rubber anti-slip sleeves for easy gripping by operators. The installation position of the grip must conform to ergonomics to ensure a stable point of force when working at heights. During the assembly phase, the scaffold top frame 601 is first fixed to the top of the upper frame 5 with screws. Spring washers are added to the screws to prevent loosening. Then, the two ends of the tie rod 602 are hinged to the top frame, and the pins are tightened after adjusting the cross angle. Finally, the fixed handles 603 are installed and their firmness and anti-slip performance are checked. After the entire fixing mechanism 6 is assembled, a simulated load test is required to verify its stability and resistance to deformation under lateral forces.

[0033] Step 4: Assembly and debugging of the overall structure After the processing and pre-assembly of the lower frame 1, middle frame 3, upper frame 5 and their auxiliary mechanisms are completed, the overall structure will enter the final assembly and commissioning stage. This stage involves assembling the modules into a complete disc-lock scaffolding system and conducting functional and safety tests to ensure that it meets the design requirements and construction standards. First, place the lower frame 1 on a flat assembly platform and adjust the height of the moving rollers 206 to make the frame level. Then, hoist the middle frame 3 and the upper frame 5 in sequence, and connect them vertically through the inserting rods 401 and the connecting frame 402. After each layer is installed, use a level to check the levelness and verticality of the frame. If the error exceeds the allowable range, it should be adjusted in time. During the final assembly process, the disc buckle fixing mechanism 4 needs to be locked one by one to ensure that the connection between the horizontal and vertical rods is firm. Each combination fixing component 403 should be tested for torque after locking to prevent structural instability due to loose bolts. At the same time, check the fit clearance between the fastener 407 and the rod to ensure that there is no looseness or jamming. The commissioning of the anti-tilt mechanism 2 is an important part of the final assembly. Based on the simulated conditions of the construction site, the angles of the connecting plate 203 and the support column 204 are adjusted to ensure that the scaffold fixing column 208 at the bottom of the support column 204 has good contact with the ground. By rotating the threaded fixing column 205, the support height is adjusted to ensure that the moving roller 206 is in a suspended or lightly touching state, so that the load is borne by the ground. Then, the fastener 209 is locked to make the support column 204 and the main frame form a triangular stable structure.
