Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a safe and environmentally friendly scaffolding for urban renewal demolition operations. Background Technology

[0002] With the acceleration of urbanization, the demand for urban renewal and demolition work is increasing. Urban demolition often involves high-rise buildings or structures. Scaffolding provides a stable working platform for construction workers, avoiding direct exposure to the risk of falling from heights. Urban demolition scenarios are diverse, and scaffolding can adapt to different terrains through adjustable support legs, modular splicing, and other methods to ensure overall stability.

[0003] In existing technologies, scaffolding commonly used in urban demolition operations mostly employs fixed or simple telescopic structures. Its mechanical structure typically includes vertical supports, horizontal connecting rods, and a bottom support device. However, existing scaffolding still suffers from significant stability issues in complex terrain or windy environments. Because traditional support structures lack multi-directional adjustment capabilities, they are prone to tilting or even collapsing when the working ground is uneven or subjected to lateral wind forces, affecting construction safety. This limits its applicability in urban renewal demolition operations. Furthermore, the height adjustment methods of traditional scaffolding are cumbersome and difficult to adapt to complex and changing construction environments. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a safe and environmentally friendly scaffolding for urban renewal demolition operations, aiming to improve the problems of traditional devices being prone to tipping over due to external forces and being inconvenient to adjust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safe and environmentally friendly scaffold for urban renewal demolition operations, comprising a support frame one, wherein an anti-tilting component is provided on one side of the outer wall of the support frame one; the anti-tilting component includes a telescopic rod one, which is disposed on one side of the outer wall of the support frame one, a telescopic rod two is slidably connected inside the telescopic rod one, a rotating shaft one is fixedly connected inside the telescopic rod two, two connecting blocks are rotatably connected to the outer wall of the support frame one, two snap-fit ​​rings are fixedly connected to the outer wall of the support frame one, a snap-fit ​​ring is fixedly connected to the outer wall of the connecting blocks, a limit hole is opened inside the telescopic rod two, two bolts are provided inside the telescopic rod one, a fixed rod is rotatably connected to one end of the telescopic rod one through a bolt, another connecting block is rotatably connected to the fixed rod, a support leg is fixedly connected to the lower surface of the fixed rod, and an adjustment component is provided inside the support frame one.

[0006] Furthermore, the adjustment assembly includes a second bracket, the outer wall of which is slidably connected to the inside of a first bracket. A gear is rotatably connected inside the second bracket, and a third bracket is slidably connected to the inner wall of the second bracket. A rack is fixedly connected to the inner wall of the first bracket, and a rack is fixedly connected to the outer wall of the third bracket. The gear teeth mesh with racks one and two. A slot is provided inside the third bracket. A locking block is fixedly connected to the outer wall of the second bracket. A rotating shaft is rotatably connected inside the locking block. A handle is fixedly connected to the outer wall of the rotating shaft. A spring is fixedly connected to the lower surface of the handle. One end of the spring is fixedly connected to the outer wall of the second bracket. A limit rod is fixedly connected to the lower surface of the handle, and the outer wall of the limit rod is slidably connected to the inner wall of the slot.

[0007] Furthermore, the outer wall of the bolt is slidably connected inside the limiting hole.

[0008] Furthermore, four brackets are provided, and a base plate is fixedly connected to the upper surface of each of the four brackets. A vertical rod is fixedly connected to the upper surface of the base plate, and a grid is fixedly connected inside the vertical rod.

[0009] Furthermore, two connecting rods are fixedly connected between the brackets, and the connecting rods are arranged in a parallel and symmetrical manner.

[0010] Furthermore, multiple limiting holes are provided, and the multiple limiting holes are arranged in a linear array at equal intervals inside the telescopic rod.

[0012] Furthermore, a reinforcing rod is provided on the outer wall of the bracket, and an anti-slip pad is fixedly connected to the lower surface of the support leg.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when it is necessary to adjust the length of the anti-tilting component, the second telescopic rod slides inside the first telescopic rod. After reaching the required length, the bolts are tightened to fix the first and second telescopic rods together. The fixed rod and the support leg provide additional support points for the scaffolding. When the scaffolding is subjected to external forces, it can resist such external forces and prevent the scaffolding from tilting. By adjusting the length and angle of the anti-tilting component, it can form a stable triangular support system with the main structure of the scaffolding. This structure can effectively disperse external forces and improve the overall stability of the scaffolding.

[0015] 2. In this utility model, through the meshing transmission of gears and racks and the multi-layer nested support structure, the adjustment component can easily achieve rapid adjustment of the scaffold height to meet the needs of different work scenarios. The design of the snap-fit ​​block and handle component ensures that the scaffold can be stably locked in the required position after the height adjustment, avoiding accidental slippage or fall due to external force, thus improving work safety. The adjustment process is simple and intuitive, and workers can quickly master the usage method without complicated training, thereby improving work efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-7 The present invention provides an embodiment of a safe and environmentally friendly scaffold for urban renewal demolition operations, comprising a support frame 5, wherein an anti-tilting component is provided on one side of the outer wall of the support frame 5;

[0026] The anti-tilt assembly includes a telescopic rod 10, which is located on one side of the outer wall of the support 5. A second telescopic rod 11 is slidably connected inside the first telescopic rod 10. The second telescopic rod 11 slides within the first telescopic rod 10, allowing for flexible adjustment of the anti-tilt assembly's length to adapt to different operational scenarios. A rotating shaft 16 is fixedly connected inside the second telescopic rod 11, providing support for the rotational connection between the second telescopic rod 11 and the connecting block 9, enabling the second telescopic rod 11 to rotate around the rotating shaft 16 and enhancing the flexibility of the anti-tilt assembly. Two connecting blocks 9 are located on the outer wall of the support 5, and one connecting block 9 is rotatably connected to the outer wall of the rotating shaft 16, achieving a rotational connection between the second telescopic rod 11 and the support 5. Two locking rings 8 are fixedly connected to the outer wall of the support 5, and one locking ring 8 is fixedly connected to the outer wall of the connecting block 9. The locking ring 8 serves to secure the connecting block 9 to the support 5. To ensure the stable installation of connecting block 9 on bracket 1 5, telescopic rod 2 11 has a limiting hole 17 inside, which is used to cooperate with bolt 18 to fix the relative position of telescopic rod 2 11 and telescopic rod 1 10. Telescopic rod 1 10 has two bolts 18 inside, which can be inserted into the limiting hole 17 to position telescopic rod 2 11. One end of telescopic rod 10 is rotatably connected to a fixed rod 12 by a bolt 18. The fixed rod 12 serves as a connection and support. The fixed rod 12 is rotatably connected to another connecting block 9, allowing the fixed rod 12 to rotate relative to the connecting block 9 to adapt to the adjustment of the anti-tilting component. The lower surface of the fixed rod 12 is fixedly connected to a support leg 13, which contacts the ground to provide additional support for the scaffold and prevent it from tilting. Bracket 1 5 has an adjustment component inside, which is used to adjust the height of the scaffold.

[0027] Reference Figures 1-7The adjustment assembly includes a second bracket 6, whose outer wall is slidably connected to the inside of a first bracket 5. The sliding of the second bracket 6 within the first bracket 5 allows for initial adjustment of the scaffold height. A gear 20 is rotatably connected inside the second bracket 6, serving as a transmission component to move the second bracket 6 and the third bracket 7. The third bracket 7 is slidably connected to the inner wall of the second bracket 6, allowing for further adjustment of the scaffold height. A rack 19 is fixedly connected to the inner wall of the first bracket 5, meshing with the gear 20 to provide support and transmission for its rotation. A rack 21 is fixedly connected to the outer wall of the third bracket 7, meshing with the gear 20 to transmit power from the gear 20 to the third bracket 7. The tooth ends of the gear 20 mesh with the racks 19 and 21, enabling sliding adjustment of the second bracket 6 and the third bracket 7 through the meshing action of the gear 20 with the racks 19 and 21. An internal slot 27 is provided, which is used to cooperate with the limiting rod 26 to fix the position of the bracket 3 7. A locking block 22 is fixedly connected to the outer wall of the bracket 2 6, which provides support for the installation of the rotating shaft 23. The rotating shaft 23 is rotatably connected inside the locking block 22, which allows the handle 25 to rotate around it. The handle 25 is fixedly connected to the outer wall of the rotating shaft 23, which facilitates height adjustment and fixing operations for the operator. A spring 24 is fixedly connected to the lower surface of the handle 25, which acts as a reset function, allowing the handle 25 to return to its initial position when no force is applied. One end of the spring 24 is fixedly connected to the outer wall of the bracket 2 6 to ensure stable installation of the spring 24. A limiting rod 26 is fixedly connected to the lower surface of the handle 25, which can be inserted into the slot 27 to fix the position of the bracket 3 7. The outer wall of the limiting rod 26 is slidably connected to the inner wall of the slot 27 to realize the cooperation between the limiting rod 26 and the slot 27.

[0028] Reference Figures 1-7Bolt 18 is slidably connected to the inner wall of limiting hole 17. The sliding and fixing of bolt 18 within limiting hole 17 allows for adjustment and fixation of the position of telescopic rod 11. Four supports 6 are provided, with base plate 3 fixedly connected to their upper surfaces. The four supports 6 provide stable support for base plate 3, which in turn provides a standing platform for construction workers. Vertical rods 1 are fixedly connected to the upper surface of base plate 3, enhancing the overall stability of the scaffolding. A grid 2 is fixedly connected inside vertical rod 1, increasing anti-slip performance for construction workers and preventing tools and materials from falling and causing injury. Connecting rods 15 are fixedly connected between supports 5. Two connecting rods 15 are arranged in a parallel and symmetrical manner, enhancing the connection between supports 5. To enhance strength and improve the overall stability of the scaffolding, multiple limiting holes 17 are provided, arranged in a linear array at equal intervals inside the telescopic rod 11. These multiple limiting holes 17 offer various length adjustment options, allowing the anti-tilting components to adapt to different anti-tilting requirements. Multiple slots 27 are provided, arranged in a linear array at equal intervals inside the support 3 7. These slots 27 enable precise adjustment and fixation of the scaffolding at various heights. The outer wall of the support 1 5 is equipped with reinforcing rods 4, which enhance the structural strength of the support 1 5 and improve the load-bearing capacity of the scaffolding. Anti-slip pads 14 are fixedly connected to the lower surface of the support leg 13, increasing the friction between the support leg 13 and the ground and further improving the stability of the scaffolding.

[0029] Working Principle: When the anti-tilting component is needed, the length of the anti-tilting component can be changed by adjusting the position of the second telescopic rod 11 within the first telescopic rod 10. The second telescopic rod 11 is rotatably connected to the connecting block 9 via the first pivot 16, and its other end is rotatably connected to the fixed rod 12 via bolts 18. The lower end of the fixed rod 12 is connected to the support leg 13. When the scaffold is subjected to lateral force, the telescopic structure formed by the first telescopic rod 10 and the second telescopic rod 11, along with each rotating connection point, forms a stable triangle, which can provide buffering and stabilization. At the same time, the support leg 13 contacts the ground, providing additional support for the scaffold and preventing it from tilting. By inserting the bolts 18 into the limiting holes 17 at different positions, the relative position of the second telescopic rod 11 and the first telescopic rod 10 can be fixed to adapt to different working conditions. To meet the needs, when height adjustment is required, bracket 26 slides on bracket 15, and bracket 37 slides on bracket 26. Gear 20 meshes with rack 19 and rack 21. When gear 20 is rotated, due to the meshing of gear 20 with rack 19 and rack 21, bracket 26 will slide within bracket 15, and bracket 37 will also slide within bracket 26, thereby adjusting the scaffold height. When the appropriate height is reached, pressing handle 25 will rotate it around shaft 23, causing limit rod 26 to move downward and insert into the corresponding slot 27 within bracket 37. At the same time, spring 24 is stretched. The cooperation between limit rod 26 and slot 27 can fix the relative position of bracket 26 and bracket 37, ensuring the stability of the scaffold height.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
