Description

Technical Field

[0001] This utility model belongs to the technical field of construction site protection devices, and specifically relates to a high-altitude edge protection device for construction sites. Background Technology

[0002] Working at heights near edges is a high-risk aspect of construction engineering, referring to work activities carried out at the edges of buildings without fixed guardrails or protective structures. Falls from heights have long been the leading cause of accidents in the construction industry, with the majority occurring in areas where work is carried out near edges. Relevant Chinese regulations mandate the installation of effective protective facilities in work areas where the fall height is 2 meters or more from the reference plane.

[0003] Traditional protective devices are mainly divided into two types: integral and detachable. Existing integral guardrails use welded frames, which ensure structural stability, but the individual units are usually large, resulting in low space utilization during transportation due to their non-disassembly nature. Detachable designs break down the device into individual components such as uprights, crossbars, and connectors. While this reduces the space required, the high degree of component dispersion makes assembly complex. Utility Model Content

[0004] Existing integral guardrails, using welded frames, while ensuring structural stability, typically have large individual unit sizes, leading to low space utilization during transportation due to their non-disassembly nature. Demountable designs break the device down into individual components such as uprights, crossbars, and connectors. While this reduces space requirements, it results in high component dispersion and complex assembly processes. This invention proposes a high-altitude edge protection device for construction sites to overcome the aforementioned technical problems of existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a high-altitude edge protection device for construction sites, including a base plate. A connecting component and a folding component are rotatably connected to the top of the base plate. Both the connecting component and the folding component are provided with limiting components inside. The limiting component inside the connecting component passes through the connecting component and is inserted into the base plate. The limiting component inside the folding component passes through the folding component and is inserted into the connecting component. The connecting component and the limiting component are used to fix the folding component, and the folding component is used for protection.

[0007] Furthermore, the connecting assembly includes a first rotating seat, the outer surface of which is fixedly connected to a first pin, the first rotating seat being rotatably connected to a base plate via the first pin, and a frame being fixedly connected to the top of the first rotating seat. There are two sets of frames, and the outer surface of each set of frames is fixedly connected to two sets of first rotating seats.

[0008] Furthermore, the folding assembly includes a second rotating seat, the outer surface of which is fixedly connected to a second pin, the second rotating seat being rotatably connected to a base plate via the second pin, a lower guardrail being fixedly connected to the top of the second rotating seat, a third rotating seat being rotatably connected to the outer surface of the lower guardrail, a third pin being fixedly connected to the outer surface of the third rotating seat, and an upper guardrail being fixedly connected to the top of the third rotating seat.

[0009] Furthermore, the limiting component includes a rotating seat, the outer surface of which is threaded with a screw, the upper end of which is fixedly connected to a square plate, and the lower end of which is fixedly connected to a plug rod. There are multiple sets of rotating seats, which are rotatably connected to the frame, the lower guardrail, and the upper guardrail, respectively. The frame has a sliding groove inside, and the screw, the square plate, and the plug rod are slidably connected inside the sliding groove.

[0010] Furthermore, threaded seats are rotatably connected to the bottom and one side of the base plate, and stud seats are fixedly connected to the other side of the base plate and the top of the frame.

[0011] Furthermore, a circular hole is provided on the outer surface of the rotating base.

[0012] Furthermore, a plug-in socket is fixedly connected to the side of the frame.

[0013] The present invention has the following advantages: 1. The present invention connects the connecting component and the folding component. Both the connecting component and the folding component are rotatably connected to the base plate. The rotation point of the folding component is lower than the rotation point of the connecting component. After the folding component is rotated to the top of the base plate, the connecting component is pressed on the top of the folding component. This can achieve quick storage, reduce the overall height, reduce the space occupied, and facilitate transportation. At the same time, the connecting component and the folding component are not separated from the base plate, which facilitates quick installation.

[0014] 2. This utility model connects the frame and the insert rod. By rotating the rotating seat on the outer surface of the frame, the rotating seat drives the insert rod to move downward, so that the insert rod extends out of the frame and is inserted into the base plate. Similarly, the insert rods in the upper and lower guardrails are inserted into the frame, thereby limiting and fixing the frame, lower guardrail and upper guardrail, and preventing unnecessary rotation of the frame, lower guardrail and upper guardrail.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-7 As shown, this utility model is a high-altitude edge protection device for construction sites, including a base plate 1. The top of the base plate 1 is rotatably connected to a connecting component 2 and a folding component 3. Both the connecting component 2 and the folding component 3 are provided with limiting components 4 inside. The limiting component 4 inside the connecting component 2 passes through the connecting component 2 and is inserted into the base plate 1. The limiting component 4 inside the folding component 3 passes through the folding component 3 and is inserted into the connecting component 2. The connecting component 2 and the limiting component 4 are used to fix the folding component 3, and the folding component 3 is used for protection.

[0029] The connecting component 2 and the folding component 3 are rotated on the top of the base plate 1. After the connecting component 2 and the folding component 3 are rotated to be perpendicular to the base plate 1, the limiting component 4 on the outside of the connecting component 2 and the folding component 3 is rotated so that the limiting component 4 inside the connecting component 2 is inserted into the base plate 1, and the limiting component 4 inside the folding component 3 is inserted into the connecting component 2, which can fix the connecting component 2 and the folding component 3. When the staff stands on the base plate 1, the folding component 3 can protect the staff on the base plate 1. The staff can walk through the connecting component 2 between multiple sets of base plates 1. After use, the limiting component 4 is released from the limiting and fixing of the connecting component 2 and the folding component 3. First, the folding component 3 is folded on the top of the base plate 1, and then the connecting component 2 is folded on the top of the folding component 3, which can reduce the space occupied.

[0030] This utility model achieves quick storage by connecting the connecting component 2 and the folding component 3. Both the connecting component 2 and the folding component 3 are rotatably connected to the base plate 1, and the rotation point of the folding component 3 is lower than the rotation point of the connecting component 2. After the folding component 3 is rotated to the top of the base plate 1, the connecting component 2 is pressed on the top of the folding component 3. The overall height is reduced, the space occupied is reduced, and transportation is convenient. At the same time, the connecting component 2 and the folding component 3 are not separated from the base plate 1, which facilitates quick installation.

[0031] In one embodiment, the connecting component 2 includes a first rotating seat 201, a first pin 202 is fixedly connected to the outer surface of the first rotating seat 201, the first rotating seat 201 is rotatably connected to the base plate 1 through the first pin 202, and a frame 203 is fixedly connected to the top of the first rotating seat 201. There are two sets of frames 203, and two sets of first rotating seats 201 are fixedly connected to the outer surface of each set of frames 203.

[0032] The frame 203 is pushed, which drives the two sets of first rotating seats 201 to rotate. The two sets of first rotating seats 201 rotate on the outer surface of the base plate 1 through the first pin 202, so that the frame 203 rotates from a horizontal state to a vertical state and is perpendicular to the base plate 1. Then, the limiting component 4 is used to limit and fix the frame 203 and the base plate 1 to avoid unnecessary rotation of the frame 203.

[0033] In one embodiment, the folding assembly 3 includes a second rotating seat 301, a second pin 302 fixedly connected to the outer surface of the second rotating seat 301, the second rotating seat 301 being rotatably connected to the base plate 1 via the second pin 302, a lower guardrail 303 fixedly connected to the top of the second rotating seat 301, a third rotating seat 304 rotatably connected to the outer surface of the lower guardrail 303, a third pin 305 fixedly connected to the outer surface of the third rotating seat 304, and an upper guardrail 306 fixedly connected to the top of the third rotating seat 304.

[0034] Pulling the upper guardrail 306 causes the third rotating seat 304 to rotate via the third pin 305, so that the upper guardrail 306 rotates to the same horizontal line as the lower guardrail 303. Then, pulling the lower guardrail 303 causes it to rotate via the second rotating seat 301 and the second pin 302, so that the lower guardrail 303 and the upper guardrail 306 are perpendicular to the base plate 1 and the frame 203 respectively. The lower guardrail 303, the upper guardrail 306 and the frame 203 are then limited and fixed by the limiting component 4.

[0035] In one embodiment, the limiting component 4 includes a rotating seat 401, with a screw 402 threadedly connected to the outer surface of the rotating seat 401. A square plate 403 is fixedly connected to the upper end of the screw 402, and a plug rod 404 is fixedly connected to the lower end of the screw 402. There are multiple sets of rotating seats 401, which are rotatably connected to the frame 203, the lower guardrail 303, and the upper guardrail 306, respectively. A sliding groove 405 is provided inside the frame 203, and the screw 402, the square plate 403, and the plug rod 404 are slidably connected inside the sliding groove 405.

[0036] When the rotating seat 401 is pushed to rotate, the rotational tendency of the screw 402 inside the rotating seat 401 is blocked by the square plate 403. At this time, the rotating seat 401 can drive the screw 402 to move the square plate 403 and the insert rod 404 to slide in the slide groove 405, so that the insert rod 404 slides out from the slide groove 405 and is inserted into the base plate 1 or the frame 203. When the insert rod 404 in the frame 203 is inserted into the base plate 1, the frame 203 can be limited and fixed. When the insert rod 404 in the upper guardrail 306 and the lower guardrail 303 is inserted into the frame 203, the upper guardrail 306 and the lower guardrail 303 can be limited and fixed.

[0037] In one embodiment, for the base plate 1, the bottom and one side of the base plate 1 are rotatably connected with threaded seats 5, and the other side of the base plate 1 and the top of the frame 203 are fixedly connected with stud seats 6.

[0038] The two sets of base plates 1 can be connected left and right or up and down through the threaded seats 5 and stud seats 6 set on both sides, which increases the range of movement of the workers and the protection range of the lower guardrail 303 and upper guardrail 306 on the base plate 1.

[0039] In one embodiment, the outer surface of the rotary seat 401 is provided with a circular hole 7.

[0040] The staff inserted the tool into the round hole 7 to increase the lever arm length, making it easier to push the tool to rotate the rotating seat 401.

[0041] In one embodiment, for the frame 203 described above, a plug-in socket 8 is fixedly connected to the side of the frame 203.

[0042] The plug-in socket 8 is used for the insertion of the plug rod 404 in the lower guardrail 303 and the upper guardrail 306, so that the lower guardrail 303, the upper guardrail 306 and the frame 203 have good connection and firmness.

[0043] Through the above technical solution, 1. By connecting the connecting component 2 and the folding component 3, both the connecting component 2 and the folding component 3 are rotatably connected to the base plate 1, and the rotation point of the folding component 3 is lower than the rotation point of the connecting component 2. After rotating the folding component 3 to the top of the base plate 1, the connecting component 2 is then pressed onto the top of the folding component 3, which can achieve quick storage, reduce the overall height, reduce the space occupied, and facilitate transportation. At the same time, the connecting component 2 and the folding component 3 are not separated from the base plate 1, which facilitates quick installation; 2. Through the connection between frame 203 and insert rod 404, rotate seat 401 on the outer surface of frame 203. Rotate seat 401 drives insert rod 404 to move downward, so that insert rod 404 extends out of frame 203 and is inserted into base plate 1. Similarly, insert rod 404 in upper guardrail 306 and lower guardrail 303 are inserted into frame 203 to limit and fix frame 203, lower guardrail 303 and upper guardrail 306, and avoid unnecessary rotation of frame 203, lower guardrail 303 and upper guardrail 306.
