[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at designated locations. The site where construction work takes place is called a "construction site" or "building site."

[0003] The utility model patent CN222084205U belongs to the field of guardrail technology, specifically a guardrail for construction, including a fixed guardrail; a sliding groove is provided in the middle of the fixed guardrail; a first locking plate is slidably connected in the middle of the sliding groove; the guardrail body is fixedly connected in the middle of the first locking plate. Through the connection between the first locking plate and the sliding groove, the efficiency of installing the first locking plate can be improved, thereby reducing the possibility of the guardrail body separating from the fixed guardrail when it is subjected to external impact, and thus reducing the possibility of the guardrail body tilting and losing its function.

[0004] Suspended platforms are used during construction. When using a suspended platform, the bottom of the platform needs to be in contact with the ground to facilitate workers getting on and off. Although the guardrail in the aforementioned patent improves the protection, a section of the guardrail needs to be removed when the suspended platform is lowered onto the walkway. Furthermore, the gaps in the guardrail reduce the overall protection of the platform. Therefore, we provide an automatically folding construction guardrail to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatically folding protective railing for construction work in order to solve the above-mentioned problems, thereby addressing the issue in the prior art where the railing needs to be disassembled and the protective capacity is reduced when the suspended platform descends over a covered walkway.

[0006] This utility model is achieved through the following technical solution: an automatically folding protective railing for building construction.

[0007] The system includes a covered walkway platform and a construction scaffold. The surface of the covered walkway platform is provided with two sets of folding mechanisms. Each folding mechanism includes a guardrail frame, a support rod, and a steel wire rope. The guardrail frame is rotatably connected to the support rod. A fixing rod is fixedly connected to the middle of the guardrail frame. A connecting bearing is rotatably connected to the surface of the fixing rod, and the steel wire rope is fixedly connected to the connecting bearing.

[0008] Preferably, a connecting plate is fixedly connected to the bottom of the support rod, and the connecting plate is assembled and connected to the corridor platform by bolts. A triangular plate for reinforcing the support rod is fixedly connected to the surface of the connecting plate.

[0009] Preferably, the bottom of the support rod is provided with an assembly hole, and the bottom of the guardrail frame is fixedly connected to the assembly rod, and the assembly rod is slidably connected to the assembly hole.

[0010] Preferably, the support rod is fixedly connected to the rear baffle of the guardrail frame, and the top of the guardrail frame is fixedly connected to a buffer pad.

[0011] Preferably, a limiting block is fixedly connected to the end of the fixing rod away from the guardrail frame, and the limiting block is located directly in front of the support rod.

[0012] Preferably, the top end of the support rod is rotatably connected to an upper pulley, and the wire rope is drivenly connected to the upper pulley, with a weight fixedly connected to the bottom end of the wire rope.

[0013] Preferably, the surface of the support rod is rotatably connected to a side pulley, and the side pulley is connected to a wire rope for transmission; the top of the guardrail frame is rotatably connected to a rotating sleeve.

[0014] This utility model provides an automatically folding safety railing for construction work, which has the following beneficial effects: 1. This automatic folding construction safety railing, when the construction scaffold is lowered, the scaffold squeezes the railing frame, causing the railing frame to flip downwards, so that the top of the railing frame abuts against the surface of the corridor platform, facilitating the entry and exit of construction personnel. When the construction scaffold is raised, the weight provides tension to the wire rope, which pulls the railing frame upwards, closing the gap in the railing. This achieves the dual goals of allowing the scaffold to land while ensuring the safety railing remains effective at all times.

[0015] 2. This automatic folding construction guardrail uses connecting plates and bolts to fix the support rods to the surface of the corridor platform. Triangular plates reinforce the support rods, improving their stability. Assembly rods are inserted into assembly holes to assemble the guardrail frame with the support rods, facilitating folding and flipping. A rear baffle prevents the guardrail frame from flipping outwards, enhancing its protective capabilities. A buffer pad provides cushioning and positioning when the guardrail frame flips downwards, preventing it from impacting the corridor platform and causing damage.

[0016] 3. This automatic folding construction guardrail uses limit blocks to provide cushioning and positioning for the guardrail frame when it flips upwards, improving the stability of the folded and restored guardrail frame. The upper pulley provides support and positioning for the wire rope, reducing friction between the wire rope and the support rod and improving the smoothness of the wire rope transmission. A weight provides tension to the wire rope, facilitating the upward flipping of the guardrail frame. Side pulleys position the wire rope, preventing the weight from impacting the bridge platform during its vertical movement, thus improving the stability of the device. A rotating sleeve reduces friction between the construction scaffold and the guardrail frame when the scaffold compresses downwards, improving the ease of folding and flipping the guardrail frame.

[0019] This utility model provides an automatically folding protective railing for building construction.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a covered walkway platform 1 and a construction hoist 2. The surface of the covered walkway platform 1 is provided with two sets of folding mechanisms 4. The folding mechanism 4 includes a guardrail frame 401, a support rod 403 and a steel wire rope 410. The guardrail frame 401 is rotatably connected to the support rod 403. A fixing rod 408 is fixedly connected to the middle of the guardrail frame 401. A connecting bearing 409 is rotatably connected to the surface of the fixing rod 408. The steel wire rope 410 is fixedly connected to the connecting bearing 409.

[0021] When the construction basket 2 descends, it presses against the guardrail frame 401, causing the guardrail frame 401 to flip downwards. This allows the top of the guardrail frame 401 to contact the surface of the corridor platform 1, facilitating the entry and exit of construction personnel. When the construction basket 2 rises, the wire rope 410 pulls the guardrail frame 401 upwards. By connecting the bearing 409 and the fixing rod 408, the friction between the wire rope 410 and the guardrail frame 401 is reduced, improving the stability of the wire rope 410 pulling the guardrail frame 401 and sealing the gap in the guardrail. This achieves the dual goals of ensuring the basket can land and that the guardrail remains effective at all times.

[0022] A connecting plate 404 is fixedly connected to the bottom of the support rod 403, and the connecting plate 404 is assembled and connected to the corridor platform 1 by bolts. A triangular plate for reinforcing the support rod 403 is fixedly connected to the surface of the connecting plate 404. The support rod 403 is fixedly installed on the surface of the corridor platform 1 by the connecting plate 404 and bolts. The triangular plate can reinforce the support rod 403 and improve the stability of the support rod 403.

[0023] The bottom of the support rod 403 is provided with an assembly hole 405. The bottom of the guardrail frame 401 is fixedly connected with an assembly rod 406, and the assembly rod 406 is slidably connected to the assembly hole 405. By inserting the assembly rod 406 into the assembly hole 405, the guardrail frame 401 and the support rod 403 are assembled together, which makes it convenient for the guardrail frame 401 to be folded and flipped.

[0024] The top of the support rod 403 is rotatably connected to an upper pulley 411, and the wire rope 410 is connected to the upper pulley 411 for transmission. The bottom of the wire rope 410 is fixedly connected to a weight 413. The upper pulley 411 provides support and positioning for the wire rope 410, reduces the friction between the wire rope 410 and the support rod 403, and improves the smooth transmission of the wire rope 410. The weight 413 provides tension to the wire rope 410, making it easier for the wire rope 410 to pull the guardrail frame 401 upward and flip it.

[0025] A side pulley 412 is rotatably connected to the surface of the support rod 403, and the side pulley 412 is connected to the wire rope 410. The pulley of the side pulley 412 extends beyond the outer edge of the corridor platform 1. A rotating sleeve 402 is rotatably connected to the top of the guardrail frame 401. The wire rope 410 is positioned by the side pulley 412 to prevent the heavy object 413 from hitting the corridor platform 1 when the wire rope 410 moves up and down, thereby improving the stability of the device operation. By rotating the sleeve 402, when the construction basket 2 presses down on the guardrail frame 401, the friction between the construction basket 2 and the guardrail frame 401 is reduced, thereby improving the convenience of flipping and folding the guardrail frame 401.

[0026] A rear baffle 407 is fixedly connected to the surface of the support rod 403 to block the guardrail frame 401. A buffer pad 414 is fixedly connected to the top of the guardrail frame 401. The rear baffle 407 blocks the guardrail frame 401 to prevent it from flipping outward and improves the protective capability of the device. The buffer pad 414 provides cushioning and positioning capabilities for the guardrail frame 401 when it flips downward, preventing the guardrail frame 401 from hitting the corridor platform 1 and causing damage to the guardrail frame 401.

[0027] The end of the fixing rod 408 away from the guardrail frame 401 is fixedly connected to the limiting block 415, and the limiting block 415 is located directly in front of the support rod 403. Through the limiting block 415, when the guardrail frame 401 is flipped upward, it provides buffering and positioning capabilities for the guardrail frame 401, thereby improving the stability of the guardrail frame 401 when it is folded back to its original state.

[0028] Working principle: The guardrail frame 401 and the support rod 403 are assembled together by inserting the assembly rod 406 into the assembly hole 405. According to the lifting and lowering position of the construction basket 2, the support rod 403 is fixedly installed on the corresponding position on the surface of the corridor platform 1 through the connecting plate 404 and bolts. When the construction basket 2 descends, the construction basket 2 squeezes the guardrail frame 401, causing the guardrail frame 401 to flip downwards. The buffer pad 414 provides cushioning for the guardrail frame 401, making it easier for construction personnel to get on and off the construction basket 2. At the same time, the guardrail frame 401 pulls the wire rope 410 upwards through the connecting bearing 409 and the fixing rod 408, raising the weight 413. After the construction basket 2 rises, the weight 413 descends and pulls the wire rope 410 to move. The wire rope 410 pulls the guardrail frame 401 upwards to close the gap in the guardrail, achieving the dual goals of the basket being able to land and the guardrail always being effective.
