Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding, in particular to a scaffolding for municipal engineering construction. Background Art

[0002] Scaffolding is an indispensable temporary facility in municipal engineering construction. Traditional scaffolding is mainly composed of components such as door frames, pedals and diagonal braces, which are fixed by bolts or clips. However, traditional scaffolding needs to be completely disassembled into multiple independent components when stored. The transportation and reassembly process is cumbersome, consuming a lot of time and manpower, and reducing construction efficiency. At the same time, the width and height of the scaffolding are fixed or have a limited adjustment range, making it difficult to adapt to the needs of different construction scenarios, especially in construction environments with limited space or special shapes.

[0003] Furthermore, in high-rise construction, materials are usually transported by manual handling or simple lifting equipment. Due to the lack of effective limiting devices and anti-sway measures, the materials are easily shifted and swayed or even fall from a high altitude due to wind influence or improper operation. The swaying materials are easy to hit the scaffolding, causing the scaffolding structure to shake, which seriously threatens the safety of construction workers on the scaffolding and ground construction workers. Summary of the Invention

[0008] As a preferred technical solution of the present invention, it also includes a connecting rope; two connecting ropes for stabilizing the feeding rod are fixedly connected to the feeding rod; and all the connecting ropes are fixedly connected to the pull rope.

[0013] As a preferred technical solution of the present invention, the fixing part is a fixing cylinder; it can cover and protect the top opening of the door frame column to prevent impurities from entering the column and adhering to the surface of the slide rail, thereby avoiding interference with the smooth operation of the feeding rod.

[0014] As a preferred technical solution of the present invention, the connecting rod and the protective rod are both hollow structures.

[0015] Beneficial effects: The present invention realizes that the door frame, pedals and diagonal braces are designed to be an integrated retractable structure, which not only realizes the flexible adjustment function of the overall width of the scaffolding, but also ensures the overall stability of the scaffolding after it is unfolded, and at the same time, improves the operational convenience and overall efficiency of the scaffolding during the disassembly and assembly process;

[0016] By allowing the feeding rod to slide smoothly along the slide rail to convey materials, the material is limited during the conveying process, effectively preventing large-area materials such as billboards from shaking or deflecting due to external forces such as wind during conveying, avoiding collisions between materials and scaffolding, thereby eliminating the risk of scaffolding shaking caused by material impact, and significantly improving the safety protection effect for workers during the construction process;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It also includes slide rails 4, feed rods 5, pull ropes 6 and adjustment components; each door frame 1 is provided with two symmetrically distributed slide rails 4; each slide rail 4 is provided with two symmetrically distributed limit slots 4001; all the slide rails 4 on one door frame 1 are slidably connected to a feed rod 5; the feed rod 5 is rotatably connected to a number of symmetrically distributed rollers 5001, and the rollers 5001 are located in the limit slots 4001; each slide rail 4 is provided with a number of retaining grooves 4002, and the distance between each upper and lower adjacent retaining grooves 4002 is 50 mm; the feed rod 5 is provided with a number of symmetrically distributed retaining rods 5002; the feed rod 5 is provided with a pull rope 6; the pedal 2 and the diagonal support rod 3 are jointly connected to the adjustment component.

[0031] The adjustment assembly includes a sleeve rod 101, a locking rod 102 and an extension plate 103; each diagonal support rod 3 is slidably connected to a sleeve rod 101; each diagonal support rod 3 is divided into two symmetrical parts; each sleeve rod 101 is slidably connected to a locking rod 102; each locking rod 102 is provided with a number of blocks 10201; each diagonal support rod 3 is provided with a number of locking holes 3001; an extension plate 103 is slidably connected to the pedal 2, and the pedal 2 is divided into two symmetrical parts; four rectangular clamps 2001 are provided on the pedal 2.

[0032] Each slide rail 4 is made of high-strength aluminum alloy, which ensures the structural strength while achieving the overall lightweight of the scaffolding.

[0033] It also includes a connecting rope 201; two symmetrically distributed connecting ropes 201 are fixedly connected to the feeding rod 5; all the connecting ropes 201 are fixedly connected to the pull rope 6.

[0034] A plurality of rubber strips are provided on the ladder of each door frame 1.

[0035] It also includes a rubber membrane 301 ; each slide rail 4 is fixed with two symmetrically distributed rubber membranes 301 .

[0036] The inner wall of each limiting groove 4001 is set to a smooth surface, which is beneficial to reducing the friction between it and the roller 5001 and facilitating labor-saving lifting of objects.

[0037] In the initial state, the scaffolding is Figure 2 When the scaffolding needs to be erected for construction, the staff will place the scaffolding in the retracted state on the ground, and then pull the locking rod 102 out of the sleeve rod 101, driving the block 10201 to disengage from the locking hole 3001, thereby releasing the locking fixation of the locking rod 102 on the diagonal brace rod 3, so that the diagonal brace rod 3 can slide in the sleeve rod 101, and then the staff will pull the two door frames 1 apart in the opposite direction, so that the door frame 1 drives the diagonal brace rod 3 to unfold. In this process, the diagonal brace rod 3 slides out in the sleeve rod 101, and the diagonal brace rod 3 is opened. The telescopic adjustment of the rod 3 allows the working distance between the two door frames 1 to be adjusted. When the distance adjustment of the two door frames 1 is completed, the staff pushes the locking rod 102 back into the sleeve rod 101, driving the block 10201 to be stuck in the locking hole 3001, so that the locking rod 102 locks and fixes the diagonal support rod 3, thereby fixing the diagonal support rod 3 on the sleeve rod 101, and locking the door frame 1 in the expanded state; then, the operator flips the pedal 2 together with the extension plate 103 on the door frame 1 upward and unfolds it, so that the pedal 2 drives the extension plate 103 to Figure 3 The vertical state is rotated into Figure 1The horizontal state shown, the extension plate 103 is pulled out from the two pedals 2 at the same time, so that the clamp 2001 on the pedal 2 is clamped on the adjacent door frame 1. In summary, the present invention cooperates with the pedal 2 and the extension plate 103 to enable the pedal 2 to be adaptively adjusted according to the actual spacing of the door frame 1, which not only realizes the flexible adjustment function of the overall width of the scaffolding, but also ensures the overall stability of the scaffolding after it is unfolded, and at the same time improves the adaptability of the scaffolding to different construction scenes. When the scaffolding is subsequently stored and transported, the present invention designs the door frame 1, pedal 2 and diagonal support rod 3 as an integrated storage structure. Compared with the prior art method of requiring the scaffolding to be completely disassembled into multiple independent components for storage, the operational convenience and overall efficiency of the scaffolding during the disassembly and assembly process are significantly improved.

[0038] When the construction height is high, the staff will erect the bottom scaffolding, and then place the next layer of scaffolding in a retracted state on the erected scaffolding pedal 2. The staff will climb up to the pedal 2 via a ladder, and accurately connect the door frame 1 of the scaffolding to be deployed to the bottom door frame 1. Then, repeat the aforementioned operation process of releasing the diagonal brace 3, and steadily pull the undocked door frame 1 to the other side to deploy the scaffolding. After the door frame 1 is fully deployed, the staff will steadily lift the entire scaffolding to accurately connect the two door frames 1 on the upper and lower layers, and finally rotate and deploy the pedal 2 into place to complete the stacking and erection operation of the scaffolding.

[0039] When the staff unfolds the bottom scaffold, they first insert the feeding rod 5 into the slide rail 4. The roller 5001 of the feeding rod 5 is located in the corresponding limit groove 4001 of the slide rail 4. When the upper and lower door frames 1 are docked, the upper door frame 1 drives the slide rail 4 to dock with the slide rail 4 on the lower door frame 1. When materials need to be transported, the staff fixes the materials on the feeding rod 5, and then the staff pulls the feeding rod 5 upwards through the pull rope 6, so that the part of the feeding rod 5 located in the slide rail 4 is in the shape of Figure 5The inclined state shown in the figure makes the roller 5001 roll in contact with the inner wall of the limiting groove 4001, thereby conveying the material to the top layer. In this process, a connecting rope 201 connected to the pull rope 6 is respectively provided at both ends of the feeding rod 5, and the connecting rope 201 is formed in a herringbone shape on the upper side of the feeding rod 5. When the pull rope 6 is pulled to drive the feeding rod 5 to rise, a symmetrical force structure is formed, which is beneficial to offset the lateral component of the feeding rod 5 during the rising process, and is beneficial to reduce the situation where the feeding rod 5 is driven by the material to deflect, and prevent the feeding rod 5 from deflecting and driving the roller 5001 to deflect in the limiting groove 4001, so as to avoid the roller 5001 being stuck in the limiting groove 4001, and ensure that the feeding rod 5 rises smoothly in the slide rail 4; in summary, the present invention realizes the object control during the conveying process by making the feeding rod 5 slide smoothly along the slide rail 4 to convey the material. The material limitation effectively prevents large-area materials such as billboards from shaking or shifting due to external forces such as wind during transportation, avoids collision between materials and scaffolding, thereby eliminating the risk of scaffolding shaking caused by material collision, and significantly improves the safety protection effect for workers during construction. At the same time, compared with the existing method of installing an electric-controlled conveying mechanism on the scaffolding, the present invention directly guides and limits the conveyed materials by integrating the slide rail 4 structure inside the door frame 1, eliminating the step of additionally setting up the electric-controlled conveying mechanism, and by integrating the slide rail 4 structure inside the door frame 1, the overall structure is simple, which not only significantly reduces the construction cost of material transportation, but also achieves the overall lightweight of the scaffolding through structural optimization, effectively reduces the installation complexity of the scaffolding, and greatly improves the operating efficiency of the scaffolding erection.

[0040] It is also taken into consideration that when the scaffolding is erected at a high height, the workers need to overcome a large vertical stroke while continuously pulling the pull rope 6 to transport materials, and are prone to arm fatigue, physical exhaustion, and the need to suspend work. Based on this, when the workers need a temporary rest while operating the pull rope 6 to transport materials, they only need to slowly release the pull rope 6 to allow the feeding rod 5 to smoothly descend along the slide rail 4 under the action of the material's own weight. During this descent, the support section of the feeding rod 5 located in the slide rail 4 will change from an upwardly inclined state to a downwardly inclined state, causing the stopping rod 5002 to contact the side wall of the limiting groove 4001. As the feeding rod 5 continues to move downward, the stopping rod 5002 is stuck in the stopping groove 4002, and the stopping rod 5002 is blocked and limited by the stopping groove 4002, thereby firmly locking the feeding rod 5 in a specific position of the slide rail 4. This not only realizes the safe suspension of the material driven by the feeding rod 5 on the slide rail 4, allowing the workers to recover their physical strength with peace of mind, but also improves the sustainability of long-term operations and the coordination of human-machine collaboration.

[0041] It is also taken into consideration that during the material conveying process, the pull rope 6 is prone to the problem of local structural strength reduction due to continuous friction; when implementing material lifting operations, there is a risk of sudden breakage of the pull rope 6, causing the feeding rod 5 and the carried materials to fall due to the loss of the traction force of the pull rope 6, which not only increases the safety risk of ground workers but also causes economic losses. Therefore, when the pull rope 6 breaks unexpectedly, the part of the feeding rod 5 located in the slide rail 4 changes from an upward tilt state to a downward tilt under the traction of the material gravity, and slides downward along the slide rail 4. During this process, the tilting action of the feeding rod 5 drives the locking rod 5002 to rotate downward, causing it to contact the side wall of the limit slot 4001. As the feeding rod 5 continues to descend, the stopping rod 5002 is embedded in the stopping groove 4002, and the stopping groove 4002 is used to block and limit the stopping rod 5002, thereby locking the feeding rod 5 in the slide rail 4, effectively preventing the feeding rod 5 and the material from continuing to fall, which not only ensures the personal safety of the ground workers, but also avoids potential economic losses. It is explained here that when the material drives the feeding rod 5 to fall, since the two adjacent stopping grooves 4002 are close to each other, the stopping rod 5002 can be quickly embedded in the stopping groove 4002, thereby effectively limiting the falling stroke of the feeding rod 5, avoiding the accumulation of excessive gravitational potential energy due to the long falling distance, and greatly reducing the scaffolding shaking caused by gravitational potential energy.

[0042] It is also taken into consideration that during the construction operation, external impurities can easily enter the limiting groove 4001 through the open groove on the slide rail 4 for the sliding of the feeding rod 5, causing the roller 5001 to be obstructed when sliding in the limiting groove 4001. Therefore, a rubber membrane 301 is provided on the outside of the open groove on the slide rail 4 for the sliding of the feeding rod 5, and the rubber membrane 301 is used to block external impurities, prevent impurities from entering the limiting groove 4001, and avoid the roller 5001 from being obstructed when sliding in the limiting groove 4001, thereby ensuring the normal transportation of materials.

[0043] Example 2: Based on Example 1, Figure 1 、 Figure 4 、 Figure 5 and Figure 8 As shown, a protection system is also included, which includes a fixing part, a connecting rod 401 and a protective rod 402; each door frame 1 is detachably connected to two fixing parts; each fixing part is fixedly connected to a connecting rod 401; each connecting rod 401 is provided with a buckle 40101; each connecting rod 401 is rotatably connected to a protective rod 402; each protective rod 402 is provided with a hook 40201.

[0044] The fixing part is a fixing cylinder 403; it can cover and protect the top opening of the column of the door frame 1 to prevent impurities from entering the column and adhering to the surface of the slide rail 4, thereby avoiding interference with the smooth operation of the feed rod 5.

[0045] The connecting rod 401 and the protective rod 402 are both hollow structures, which achieves lightweight protection structure.

[0046] It is also taken into consideration that when the scaffolds are stacked higher, the risk for workers working on them is higher and there is a risk of accidental falling. Therefore, when the scaffolds are stacked, the workers will sleeve the fixing tube 403 onto the column of the door frame 1, and hook the hooks 40201 on the protective rod 402 between the two door frames 1 to each other, and at the same time hook the hook 40201 of the protective rod 402 on the same door frame 1 into the buckle 40101 of the connecting rod 401 on the same door frame 1, so that the combination is as follows Figure 1 In the protective state shown, the guardrail composed of the connecting rod 401 and the protective rod 402 encloses the working area of ​​the construction platform, protects the workers during the construction process, prevents the workers from accidentally falling, and enhances the protection effect on the workers. At the same time, the top opening of the column of the door frame 1 is covered and protected by the fixed cylinder 403 to prevent impurities from falling into the internal space of the column from the opening during construction, and prevents impurities from adhering to the surface of the slide rail 4 and interfering with the smooth operation of the feeding rod 5, thereby ensuring the continuous and stable operation of the material conveying system.
