[0021] like Figures 1 to 4 As shown, the present invention provides a roller-driven horizontal safety suspension system for facade construction, comprising two groups of suspension components, and a plurality of connecting rods are vertically connected between the two groups of suspension components; wherein each group of suspension components is provided with: An L-shaped hanging rod, comprising a transverse rod 100 and a vertical rod 101 connected vertically, wherein the transverse rod 100 is located at the top of the wall 400, and the vertical rod 101 is hung on the outside of the wall 400; A clamping rod 200, which is located on the inner side of the wall 400, and the clamping rod 200, the transverse rod 100, and the vertical rod 101 are installed with a plurality of rollers 201 that roll in the horizontal direction on a side close to the wall 400; The clamping and positioning assembly is provided with a rectangular frame 300, and a first sliding ring 301 and a second sliding ring 302 are respectively slidably sleeved on two opposite edges of the rectangular frame 300. The top of the first sliding ring 301 is fixedly connected with a first connecting rod 303, and the extended end of the first connecting rod 303 is coaxially fixedly connected to the transverse rod 100. The bottom of the second sliding ring 302 is fixedly connected with a second connecting rod 304, and the extended end of the second connecting rod 304 is vertically fixedly connected to the clamping rod 200. The rectangular frame 300 and the clamping rod 20 0 is provided with a rotating shaft 305, and a rotating rod 306 is rotatably provided on the rotating shaft 305. Long strip openings 307 are opened at both ends of the rotating rod 306. Limiting protrusions 308 are installed on the first connecting rod 303 and the second connecting rod 304. The two limiting protrusions 308 are matched and accommodated in the corresponding long strip openings 307. A hydraulic cylinder 309 is installed on the edge of the rectangular frame 300 that is away from the clamping rod 200. The end of the piston rod of the hydraulic cylinder 309 is connected to the second sliding ring 302 through a fixing rod 310.

[0022] In the technical solution, the roller-driven horizontal safety suspension system for facade construction is provided with two groups of suspension components suspended on the wall 400 in parallel, and a plurality of connecting rods are connected between the two groups of suspension components. Each group of suspension components includes a clamping rod 200 located on the inner side of the wall 400 and an L-shaped suspension rod located on the outer side of the wall 400, and the two are connected by a clamping positioning assembly, and the clamping positioning assembly includes a rectangular frame 300 surrounded by four edges, and the first sliding ring 301 and the second sliding ring 302 are slidably installed on the upper and lower parallel transverse edges of the rectangular frame 300, wherein the first sliding ring 301 is connected to the L-shaped suspension rod through a first connecting rod 303, and the second sliding ring 302 is connected to the clamping rod 200 through a second connecting rod 304, and connected to the wall 400. A rotating shaft 305 is installed on a vertical edge close to the wall 400, and a rotating rod 306 is rotatably installed on the rotating shaft 305. Long strip openings 307 are provided at both ends of the rotating rod 306. Two limiting protrusions 308 are slidably accommodated in the two holes. The two limiting protrusions 308 are fixedly connected to the first connecting rod 303 and the second connecting rod 304 respectively. A hydraulic cylinder 309 is fixedly installed on a vertical edge away from the wall 400. The piston rod of the hydraulic cylinder 309 is extended and retracted in a direction perpendicular to the wall 400, and the free end of the piston rod is connected to the second sliding ring 302 through a fixed rod 310. The clamping rod 200 and the L-shaped hanging rod are both installed with a plurality of rollers 201 on the inner side close to the wall 400. When in use, the hydraulic cylinder 309 drives the piston rod to retract, the clamping rod 200 and the L-shaped hanging rod are separated, and the rod is put on the wall 400 from above, so that the L-shaped hanging rod is located outside the wall 400, and the clamping rod 200 and the clamping positioning assembly are located inside the wall 400. After the position is fixed, the hydraulic cylinder 309 is started to drive the piston rod to extend, and the clamping rod 200 and the L-shaped hanging rod move toward the wall 400 at the same time and clamp, and the construction personnel start construction. When horizontal movement is required, the piston rod is slightly shortened when the hydraulic cylinder 309 is started until the roller 201 can move smoothly. The roller 201 rotates and drives the system to move horizontally along the wall 400. In this technical solution, the distance between the clamping rod 200 and the L-shaped hanging rod is adjusted by the clamping positioning assembly to meet the use of walls 400 of different thicknesses and increase the applicability of the structure. The first linkage rod 303 and the second linkage rod 304 are linked by the rotating rotating rod 306, so that when clamping and positioning, the clamping rod 200 and the L-shaped hanging rod simultaneously exert force on both sides of the wall 400, ensuring the stability and balance of the hanging system during movement and avoiding the impact on the wall 400 during use. The roller 201 drives the hanging system to move laterally outside the wall 400, effectively improving the construction efficiency.

[0023] In another technical solution, the rotating shaft 305 and the two limiting protrusions 308 are both located on the same side of the rectangular frame 300, and the axial direction of the rotating shaft 305 is perpendicular to the sliding direction of the first sliding ring 301 and the second sliding ring 302, and the rotating shaft 305 is located on the center line of the rectangular frame 300. In this technical solution, the rotating shaft 305 is located on the center line of the rectangular frame 300, and the hydraulic cylinder 309 drives the first sliding ring 301 to move, thereby pushing the first linkage rod 303 to move, and at the same time, the left and right swing of the rotating rod 306 realizes the linkage of the first linkage rod 303 and the second linkage rod 304, and finally makes the clamping rod 200 and the L-shaped suspension rod approach and move away from each other, so as to adapt to the use of walls of different thicknesses and improve the flexibility of the structure.

[0024] In another technical solution, two long strip openings 307 are symmetrically located on both sides of the rotating rod 306, and the length direction of the two long strip openings 307 is consistent with the axial direction of the rotating rod 306. In this technical solution, the two long strip openings 307 are symmetrical to each other, thereby improving structural stability.

[0025] In another technical solution, the movement direction of the piston rod of the hydraulic cylinder 309 is consistent with the sliding direction of the first sliding ring 301 and the second sliding ring 302, and the two ends of the fixed rod 310 are respectively connected vertically with the second sliding ring 302 and the free end of the piston rod. In this technical solution, the piston rod of the hydraulic cylinder 309 is extended or shortened, driving the second sliding ring 302 to move right or left, and the first sliding ring 301 is linked to move left or right, so as to achieve the clamping or loosening of the clamping rod 200 and the L-shaped suspension rod, which is convenient for operation and convenient for use. In another technical solution, it also includes two side protection components, which include two groups of upper guardrails 311 installed on the top of the transverse rods 100 of the two groups of suspension components, and two groups of lateral guardrails 312 installed on the outside of the two groups of vertical rods 101. In this technical solution, multiple groups of guardrails are set to enhance the side protection capability, which can effectively resist risks from the side, such as strong winds, collisions, etc., thereby improving the safety of construction personnel and ensuring the smooth progress of the construction process.

[0026] In another technical solution, a stepping steel plate is connected and installed between the bottom ends of the two sets of lateral guardrails 312, and a plurality of connectors 313 are connected and installed between the outer sides of the two sets of lateral guardrails 312. In this technical solution, the connectors provide comprehensive external protection for construction workers, effectively preventing the risk of accidental falls of construction workers during high-altitude operations. By setting up a multi-layer protection structure, the safety of construction workers can be ensured even in complex and changeable external environments.

[0027] In another technical solution, the tread steel plate is provided with anti-skid embossing. In this technical solution, the tread steel plate adopts an anti-skid structure to ensure that construction workers can stand stably during operation and avoid accidents caused by slipping or losing their footing.

[0028] In another technical solution, the plurality of rollers 201 are further connected to a drive motor 203. In this technical solution, the rollers 201 are connected to the drive motor 203 to achieve smooth lateral movement of the safety suspension system and improve construction efficiency.

[0029] like Figure 5 As shown, the above technical scheme may also include the following technical details to better achieve the technical effect: each roller 201 is provided with a C-shaped roller 202, both ends of the roller 202 are fixedly mounted on the corresponding rod body, the roller is rotatably sleeved on the outer periphery of the roller 202, the roller on the transverse rod 100 close to the clamping rod 200 is set as the first roller 210, and the roller on the clamping rod 200 close to the transverse rod 100 is set as the second roller 211. The first roller 210 is coaxially fixed with a first worm gear 212, and two fixed blocks 213 are provided at the bottom of the transverse rod 100. A worm 214 meshing and rotating with the first worm gear 212 is rotatably installed between the two fixed blocks 213. The end of the worm gear 214 is coaxially fixed with the rotating shaft of the driving motor 203, and the second roller 211 is coaxially fixed with a first bevel gear 215. The first fixed shaft and the second fixed shaft are installed on the side of the clamping rod 200 close to the wall. The outer peripheral rotation sleeve of the first fixed shaft is provided with a first sprocket and a second bevel gear 216, and the second bevel gear 216 meshes and rotates with the first bevel gear 215. The outer peripheral rotation sleeve of the second fixed shaft is provided with a second sprocket and a second worm gear 217. A transmission chain 218 is connected between the first sprocket and the second sprocket, and the second worm gear 217 meshes and rotates with the worm 214. When in use, the drive motor 203 is started to drive the worm 214 to rotate, and at the same time drives the second sprocket and the first worm 212 to rotate, and the second sprocket drives the first sprocket, the second bevel gear 216, and the first bevel gear 215 to rotate in sequence, and then drives the first roller 210 and the second roller 211 to rotate synchronously, and drives the roller-driven horizontally running safety suspension system used for facade construction to move horizontally. In this technical solution, through the linkage of multiple sprockets, bevel gears, and worm wheels and worm 214, a drive motor 203 can drive the first roller 210 and the second roller 211 to rotate synchronously, and then the entire safety suspension system can move horizontally stably, thereby improving the structural stability.

[0030] The above roller-driven horizontal safety suspension system for facade construction includes the following steps when used and installed: Step 1: System installation: S1: First, the bridge's crash wall was evaluated to ensure that its structural strength was sufficient to support the suspension system.

[0031] S2: Weld two sets of suspension components and multiple connecting rods in advance and install them at appropriate positions on the crash barrier. The rods used should be firmly fixed on the crash barrier to bear the weight of the entire system and the dynamic load during construction.

[0032] S3: Install multiple rollers 201 and rollers 202, including a first roller 210 and a second roller 211, wherein the first roller 210 and the second roller 211 are coaxially fixed to the first worm gear 212 and the first bevel gear 215 respectively, two fixed blocks 213, a worm 214, and a drive motor 203 are installed at the bottom of the transverse rod 100, and a first fixed shaft and a first sprocket and a second bevel gear 216 are installed on one side of the clamping rod.

[0033] S4: Start the hydraulic cylinder 309 to drive the piston rod to extend, and the clamping rod 200 and the L-shaped suspension rod move toward the wall at the same time to ensure that the roller is in good contact with the side of the bridge or the wall.

[0035] Step 2: Install the protective components on both sides: The upper guardrail, side guardrail and multiple connectors of the two side protection components are installed to form a complete external protection barrier to prevent construction workers from falling from the outside. These protection systems not only provide physical barriers, but also enhance the psychological safety of construction workers.

[0036] Step 3: Bottom protection and construction preparation: S1: Install steel plates at the bottom of the protective components on both sides to provide a solid foothold for construction workers. The steel plates should be non-slip, wear-resistant, and have a certain load-bearing capacity.

[0037] S2: Check whether all parts are installed in place and fastened securely. After confirmation, conduct safety inspection and test run to ensure stable operation of the system.

[0038] Step 4: Construction work: S1: Construction workers step onto the treadle steel plate and drive the first roller 210 and the second roller 211 to rotate synchronously through the drive motor 203, so that the system moves horizontally to the working position on the side of the bridge.

[0039] S2: Carry out painting, maintenance or installation work on the platform. Since the system provides comprehensive protection and stable support, construction workers can focus more on the work itself and improve construction quality and efficiency.

[0040] Step 5: Operation completion and system dismantling: S1: After the operation is completed, the construction personnel exit the system according to the established procedures.

[0041] S2: Maintain and service the suspension system as needed to ensure its long-term performance.
