Description

Technical Field

[0001] This utility model relates to the field of building climbing formwork technology, and in particular to a building climbing formwork anti-fall structure. Background Technology

[0002] Climbing scaffolding (also known as attached lifting scaffolding) is an external protective scaffolding system used in the construction of high-rise buildings. It is attached to the building structure and rises and falls layer by layer as the construction progresses, replacing traditional cantilever scaffolding. Its core features are mechanization, modularization, and intelligence, which can significantly improve construction efficiency and reduce safety risks. The anti-fall structure is the core safety device of the climbing scaffolding. Its main function is to automatically lock in the event of a sudden fall of the scaffolding during lifting or use, so as to prevent high-altitude fall accidents.

[0003] While current construction projects use attached lifting scaffolds equipped with basic fall arrest devices, the limiting mechanisms of these devices often employ independent structural designs, lacking the synergistic effect of multi-level buffering mechanisms and redundant protective components. Under extreme conditions, when the scaffold is triggered to fall freely due to mechanical failure or unexpected loads, its instantaneous falling speed is high, leading to increased instantaneous impact loads on the supporting components. In such impacts, deformation or even cracks may occur in the contact areas of the supporting components. In subsequent use, repeated impacts will exacerbate the deformation of the supporting components, resulting in reduced structural strength and even breakage, posing a risk of the climbing scaffold falling. Therefore, we urgently need a fall arrest structure for construction climbing scaffolds to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the limiting mechanism of the existing anti-fall device is mostly an independent structure design, which lacks multi-level buffering and leads to excessive impact force when the climbing formwork falls. Therefore, this invention proposes an anti-fall structure for building climbing formwork.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fall prevention structure for a building climbing scaffold includes a mounting frame detachably installed on a wall and a support plate slidably connected to the mounting frame. The mounting frame is fixedly installed to the support plate via rivets and upper limit holes. The structure also includes: a U-shaped frame symmetrically installed on the support plate; a movable plate slidably connected inside the U-shaped frame; a connecting rod hinged to the lower part of the movable plate; a round rod hinged to the middle of the connecting rod, with both ends of the round rod fixedly installed to the inner wall of the U-shaped frame; and a mating plate fixedly attached to the end of the connecting rod. When the movable plate moves, the two mating plates rotate and form a deceleration zone. A connecting block slidably connected to the U-shaped frame is also included. A coil is fixedly installed at the bottom of the connecting block, with a steel wire rope wound on the coil. The end of the steel wire rope is fixedly connected to a buckle for connecting to the climbing scaffold.

[0007] To enable the movable plate to move, preferably, slide rails are fixedly connected to both inner walls of the U-shaped frame, the movable plate is slidably connected to the slide rails, and a second steel wire rope is fixedly connected to the movable plate, with the end of the second steel wire rope passing outward and fixedly connected to the connecting block. When the connecting block and the second steel wire rope move downward, the movable plate moves along the slide rail path.

[0008] To further support the movable plate, hydraulic rods are symmetrically installed on the inner wall of the U-shaped frame, and the output ends of the hydraulic rods are fixedly connected to the movable plate.

[0009] In order to allow the connecting block to slide, preferably, a sliding plate is symmetrically installed on a U-shaped frame, with both ends of the connecting block slidably connected inside the sliding plate, a sleeve fixedly connected to the bottom of the sliding plate, a support rod slidably connected inside the sleeve, the end of the support rod being fixedly connected to the connecting block, and a spring sleeved on the outside of the sleeve, with both ends of the spring connected to the bottom wall of the sliding plate and the connecting block respectively.

[0010] To provide resistance during the descent of the climbing frame, preferably, a damping plate is detachably installed on the bonding plate, and the coefficient of friction between the damping plate and the climbing frame is in the range of 0.6μ-0.8μ.

[0011] To further improve fall protection performance, the damping plate is made of steel-modified rubber.

[0012] Compared with the prior art, this utility model provides a fall prevention structure for building climbing scaffolds, which has the following beneficial effects:

[0013] The anti-fall structure of this building climbing formwork uses a damping plate on the bonding plate. When the climbing formwork falls, the moving plate moves towards the U-shaped frame under the action of the connecting block. This causes the connecting rod to move the damping plate on the bonding plate to fit against the surface of the climbing formwork. The resistance formed between the damping plate and the climbing formwork reduces the impact force when the climbing formwork falls and effectively suppresses the speed of the fall. Combined with the original anti-fall device, this improves the anti-fall performance.

[0014] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model reduces the impact of the climbing frame on the original support components when it falls at high speed, avoids the breakage of the support components due to the impact, effectively provides a multi-level buffer mechanism, and improves the fall protection performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] Reference Figures 1-4 A fall protection structure for a building climbing scaffold includes a mounting frame 1 detachably installed on a wall and a support plate 2 slidably connected to the mounting frame 1. The mounting frame 1 is fixedly installed to the support plate 2 via rivets and upper limit holes. Here, the mounting frame 1 is installed on the wall and located outside the original fall protection device on the climbing scaffold. This device assists the original fall protection device, thereby effectively providing a fall protection effect. The support plate 2 can be adjusted outward in length according to the distance between the climbing scaffold and the wall. After adjustment, it can be connected by rivets. The structure also includes:

[0024] A U-shaped frame 3 is symmetrically installed on the support plate 2. A movable plate 4 is slidably connected inside the U-shaped frame 3. A connecting rod 5 is hinged to the lower part of the movable plate 4. A round rod 6 is hinged to the middle of the connecting rod 5, and both ends of the round rod 6 are fixedly installed to the inner wall of the U-shaped frame 3. A mating plate 7 is fixedly attached to the end of the connecting rod 5. A damping plate 19 is detachably installed on the mating plate 7. The coefficient of friction between the damping plate 19 and the climbing frame is in the range of 0.6μ-0.8μ, preferably 0.7μ. When the damping plate 19 contacts both sides of the climbing frame, it can provide a good friction effect, thereby suppressing the falling speed of the climbing frame through the resistance formed. Together with the original anti-fall device, it achieves efficient anti-fall performance. The material of the nylon plate 19 is steel-modified rubber. By adding steel, steel-modified rubber has higher tensile strength, compressive strength and wear resistance, making it suitable for use in harsh working conditions. Steel-modified rubber exhibits better durability in environments with high wear, extending its service life, and its impact resistance is enhanced, making it suitable for applications that need to withstand large impact loads. Steel-modified rubber can maintain its stability at high temperatures, further improving the suppression effect during the scaffold's descent. Therefore, when the moving plate 4 moves, it will drive the connecting rod 5 to move backward. The bonding plate 7 at the end of the connecting rod 5 rotates outward and contacts the surface of the scaffold to form a deceleration zone.

[0025] A connecting block 8 is slidably connected to the U-shaped frame 3. A wire reel 9 is fixedly installed at the bottom of the connecting block 8, and a steel wire rope 10 is wound on the wire reel 9. Here, the wire reel 9 has an automatic winding function, which is a conventional technical solution and will not be described in detail here. The end of the steel wire rope 10 is fixedly connected to a buckle 11 for connecting with the climbing frame. A sliding plate 15 is symmetrically installed on the U-shaped frame 3. The two ends of the connecting block 8 are slidably connected to the sliding plate 15. A sleeve 16 is fixedly connected to the bottom of the sliding plate 15. A support rod 17 is slidably connected inside the sleeve 16. The end of the support rod 17 is fixedly connected to the connecting block 8. A spring 18 is sleeved on the outside of the sleeve 16, and the two ends of the spring 18 are respectively connected to the bottom wall of the sliding plate 15 and the connecting block 8. Slide rails 12 are fixedly connected to both inner walls of the U-shaped frame 3. A moving plate 4 is slidably connected to the slide rails 12. Hydraulic rods 13 are symmetrically installed on the inner wall of the U-shaped frame 3, and the output end of the hydraulic rod 13 is fixed to the moving plate 4. A steel wire rope 14 is fixedly connected to the movable plate 4, with the end of the steel wire rope 14 extending outward and fixedly connected to the connecting block 8. When the connecting block 8 and the steel wire rope 14 move downward, the movable plate 4 moves along the slide rail 12. Here, because the buckle 11 is directly connected to the climbing frame, when the climbing frame falls, the buckle 11 will pull the steel wire rope 10 on the reel 9 downward. When the steel wire rope 10 reaches its maximum stroke, the connecting block 8 will press down the support rod 17, causing the connecting block 8 to move downward and pull the steel wire rope 14, causing the movable plate 4 connected to the steel wire rope 14 to move backward. When the movable plate 4 moves backward and pushes the connecting rod 5 backward, the damping plate 19 on the contact plate 7 at the end of the connecting rod 5 will contact the surface of the climbing frame, thereby forming resistance and effectively reducing the falling speed of the climbing frame. This facilitates the original anti-fall components to support the climbing frame, thereby improving the anti-fall effect and reducing the impact on the original anti-fall components.

[0026] In this invention, the mounting bracket 1 is fixedly installed on the wall and located outside the original fall protection device. The two U-shaped brackets 3 are positioned outside the climbing frame by adjusting the extension length of the support plate 2, so that the contact plate 7 can contact the surface of the climbing frame when it is removed. At this point, the buckle 11 is connected to the climbing frame, completing the assembly of the auxiliary fall protection device. When the climbing frame falls, it drags the buckle 11 downwards. When the buckle 11 moves downwards, it pulls the steel wire rope 10 on the reel 9 downwards. When the steel wire rope 10 reaches its maximum travel, it pulls the connecting block 8 downwards within the slide plate 15. Simultaneously with the downward movement of the connecting block 8, it pulls... The second steel wire rope 14 is moved, dragging the moving plate 4 backward and pushing the connecting rod 5 backward, so that the damping plate 19 on the contact plate 7 contacts the surface of the climbing frame to form resistance. Combined with the original anti-fall device, the climbing frame is fixed. When the climbing frame rises again, the buckle 11 rises with the climbing frame, and the first steel wire rope 10 changes from taut to loose. Combined with the automatic winding function of the coil 9, the first steel wire rope 10 is retracted. The connecting block 8 moves upward under the action of the spring 18. The moving plate 4 is reset due to the loosening of the second steel wire rope 14 and the cooperation of the hydraulic rod 13. The connecting rod 5 is reset as well. The damping plate 19 on the contact plate 7 is disengaged from the climbing frame, thus contacting the limit of the climbing frame.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
