[0043] During the construction of the steel structure power distribution building, there are a lot of high-altitude operations. The edge height of the equipment platform of the power distribution building can often reach 4 to 5 meters, and the edge height of the roof can even reach 13 to 15 meters. Therefore, there is a risk of falling from height during the construction of corrugated steel plates, floor decking, floor steel bar binding, water and electricity pipeline laying, concrete pouring, etc. In order to achieve the project safety goals and help the project to be put into operation on schedule, it is particularly necessary to set up protective fences around the steel frame of the power distribution building.

[0044] The traditional method is to weld the guardrail uprights directly to the steel beam.

[0045] However, welding will destroy the anti-corrosion coating at the joints. Subsequently, due to the influence of concrete operations and rainy and snowy weather, rust will appear at the joints, affecting the construction quality.

[0046] In order to solve the above technical problems, the present disclosure proposes an edge protection device and a method of using the same, which can avoid directly welding the guardrail uprights to the steel beam to damage the anti-corrosion coating.

[0047] Example 1

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, an edge protection device includes a support member 1, a telescopic member 2 and a protection assembly 6, the support member 1 is provided with a first flange 12 and a second flange 11, an accommodating space is formed between the first flange 12 and the second flange 11, and a first clamping portion 4 and a second clamping portion 3 are respectively provided on opposite sides of the first flange 12 and the second flange 11; the telescopic member 2 can be telescoped in its extension direction, the first end of the telescopic member 2 cooperates with the first clamping portion 4, and the second end of the telescopic member 2 cooperates with the second clamping portion 3 after the telescopic member 2 is extended; the protection assembly 6 is fixedly connected to the telescopic member 2.

[0049] The support member 1 refers to a mechanical component used to fix the guardrail to the steel structure. Its main function is to attach to the steel beam in a non-destructive manner (such as clamping, bolting, etc.) to ensure that the protective assembly 6 can be installed safely and reliably, and will not damage the anti-corrosion coating of the steel beam during construction. Specifically, the support member 1 can be integrally formed with the steel structure or fixedly connected to the steel structure. The support member 1 can be a standard support member 1, such as an H-shaped steel beam or an I-shaped steel beam, whose structure and size are designed according to general standards and are easy to mass produce and install. The support member 1 can also be a customized support member 1, which can be a steel beam of a special shape or size (such as a special-section steel beam), which needs to be customized according to the specific engineering situation to ensure the best matching and safety. The support member 1 can also be a lightweight support member 1, made of high-strength but light-weight materials, such as aluminum alloys or composite materials, which is suitable for scenarios with load restrictions. The support 1 can also be a heavy-duty support 1, designed to carry a larger load, suitable for high-risk areas or large engineering projects, usually made of thicker steel, with higher strength and durability. The support 1 can also be a portable support 1, designed for temporary or highly mobile construction sites, easy to install and remove quickly, usually equipped with a simple connection mechanism, such as quick-release locks or bolts. The support 1 can also be a modular support 1, consisting of multiple independent units, which can be flexibly combined according to actual needs, suitable for steel beams of different lengths or complex layouts.

[0050] The support member 1 can be a part of the steel structure, or can be formed integrally with the steel structure. For example, the steel structure can be an I-beam at the edge of the steel structure. The protection assembly 6 is directly connected to the I-beam to ensure the stability of the connection. The support member 1 can also be connected to the steel structure by bolts or other fixing methods.

[0051] The two flanges, the first flange 12 and the second flange 11, constitute the main frame of the support member 1. They are arranged in parallel, and a receiving space is formed between them to accommodate the telescopic member 2. The design of the flange should take into account the fit with the contact surface of the steel beam to ensure sufficient friction and stability. The receiving space is formed by the area between the first flange 12 and the second flange 11. The size of the space needs to be designed according to the actual size of the telescopic member 2 to ensure that the telescopic member 2 can move freely in it without hindrance.

[0052] The first clamping part 4 and the second clamping part 3 are respectively located on the first flange 12 and the second flange 11 of the support member 1, and their main function is to provide a fixing point for the telescopic member 2 and ensure that the telescopic member 2 can be stably locked at a predetermined position. Specifically, the first clamping part 4 is located on the first flange 12 of the support member 1, and cooperates with one end of the telescopic member 2 to provide initial fixation when the telescopic member 2 is in a contracted state. The second clamping part 3 is located on the second flange 11 of the support member 1, and cooperates with the other end of the telescopic member 2 to provide a final locking position when the telescopic member 2 is fully extended. The first clamping part 4 and the second clamping part 3 can be a groove, a hole or a special buckle structure. More specifically, the first clamping part 4 and the second clamping part 3 can be a hole-type clamping part, with a circular or elliptical hole on the flange for inserting a pin or bolt on the telescopic member 2, which is simple and easy to use, quick to install, and suitable for conventional steel structure beams, especially those with relatively flat surfaces. More specifically, the first clamping portion 4 and the second clamping portion 3 may be groove-type clamping portions, and a long strip or U-shaped groove is provided on the flange, and the end of the telescopic member 2 can slide into and lock in the groove, providing a larger contact area and enhancing stability, which is suitable for occasions where the length of the telescopic member 2 needs to be adjusted frequently.

[0053] The first clamping part 4 and the second clamping part 3 can be snap-on type clamping parts, using a spring-loaded snap-on mechanism, and the end of the telescopic member 2 has a corresponding protrusion or depression, which can automatically lock into the snap-on. It is very convenient to install and remove, and no additional tools are required. The self-locking design improves safety. It is suitable for temporary or highly mobile construction sites, and is easy to install and remove quickly.

[0054] The first clamping part 4 and the second clamping part 3 can be threaded clamping parts, an internal thread hole or a sleeve with an internal thread hole is provided on the flange, and the end of the telescopic part 2 has an external thread, and the two are connected by threads. The connection is firm, the vibration resistance is good, and the length of the telescopic part 2 can be accurately adjusted. It is suitable for occasions with high requirements for fixing accuracy, such as precision engineering or long-term use of protective facilities.

[0055] Specifically, the first clamping portion 4 and the second clamping portion 3 can be integrally formed with the support member 1 to ensure the connection strength. The clamping portion is fixed to the flange of the support member 1 using high-strength bolts, and can be equipped with washers and flat washers to increase the contact area and prevent loosening. It is easy to install and disassemble, easy to maintain and replace without damaging the anti-corrosion coating of the steel beam, and has a firm connection and good vibration resistance. In order to improve stability and safety, the support member 1 may be equipped with additional anti-slip designs or auxiliary fixing devices. The support member 1 may also have an adjustable function to adapt to steel beams of different widths or shapes.

[0056] The telescopic member 2 is a key component in the edge protection device. It can freely expand and contract in its extension direction to adapt to steel beams of different widths and ensure that the guardrail can be firmly fixed on the steel beam. The main function of the telescopic member 2 is to achieve the conversion from the contracted state to the fully extended state by cooperating with the first clamping part 4 and the second clamping part 3 of the support member 1, thereby providing stable support and protection.

[0057] The telescopic member 2 is made of high-strength metal material (such as aluminum alloy, stainless steel or carbon steel) and has sufficient strength and durability. The main structure can be a single tube or multi-tube design, and the multi-tube design can realize the telescopic function by means of a sleeve. Specifically, the telescopic can be realized by sliding between the inner and outer tubes, and the inner tube can move freely in the outer tube. The telescopic can also be realized by threaded connection, and the telescopic length can be adjusted by rotation. More specifically, the telescopic member 2 can also include a locking mechanism for locking the telescopic member 2 after it reaches the required length to prevent accidental telescopic extension. For example, the locking mechanism can be a pin, a lock, a bolt, etc. The two ends of the telescopic member 2 can be provided with specific clamping parts to cooperate with the first clamping part 4 and the second clamping part 3 of the support member 1. These clamping parts can be pins, latches, buckles, threads, etc., and the specific form depends on the design of the clamping part. Some telescopic members 2 can also be equipped with rubber gaskets or similar materials to increase the friction with the surface of the steel beam to prevent sliding. The telescopic member 2 may also have an adjustable function to adapt to steel beams of different shapes and sizes.

[0058] Specifically, the telescopic member 2 can be a single-tube telescopic member 2, which is composed of a telescopic tubular structure, and usually adopts a sliding or spiral telescopic mechanism. It has a simple structure, low cost, light weight, is easy to carry and install, and is suitable for steel beams with little width change and low load requirements. The telescopic member 2 can also be a double-tube telescopic member 2, which is composed of two nested tubes, the outer tube is fixed, and the inner tube can slide in the outer tube. The double-tube telescopic member 2 has a large telescopic range, which is suitable for steel beams of different widths, and has a stable structure and strong bearing capacity. Double-tube telescopic is suitable for construction environments with medium loads and large width changes. The telescopic member 2 can be a multi-tube telescopic member 2, which is composed of three or more nested tubes, which are telescoped layer by layer to form a longer telescopic range. The telescopic range of the telescopic member 2 is very large, which is suitable for extremely wide steel beams, and the length can be accurately adjusted to adapt to complex construction conditions.

[0059] The telescopic member 2 can be a spiral telescopic member 2, which is telescopically connected by a threaded connection, and a thread can be set between the outer tube and the inner tube. It has high telescopic accuracy and is suitable for occasions that require precise adjustment. It has a firm connection and good vibration resistance. It is suitable for occasions that require high fixing accuracy, such as precision engineering or protective facilities for long-term use. The telescopic member 2 can be a hydraulic telescopic member 2, which is driven to telescope by a hydraulic system, equipped with a hydraulic cylinder and a control valve, with a fast telescopic speed and easy operation. The hydraulic telescopic member 2 has a large carrying capacity and is suitable for high-load scenarios, such as bridges, tunnels and other construction environments with high loads and high precision requirements. The telescopic member 2 can also be an electric telescopic member 2, which is driven to telescope by an electric motor, usually equipped with a control system and a sensor, with a fast telescopic speed, a high degree of operation automation, and can achieve remote control and monitoring to improve construction efficiency. The electric telescopic member 2 is suitable for intelligent construction projects, such as intelligent buildings, automated production lines, etc.

[0060] The protection component 6 is a key part of the edge protection device that is directly used to prevent construction workers from falling. It is usually fixedly connected to the telescopic member 2 and installed on the steel beam or support member 1 to form a complete protection system. The main function of the protection component 6 is to provide a physical barrier to prevent workers from approaching the dangerous edge and provide sufficient support and cushioning when an accident occurs to ensure the safety of the workers.

[0061] The protection component 6 may include a railing, a mesh, a warning sign and a buffer device. The railing may also include a column, a crossbar, an intermediate rod, a handrail and a skirting board. The column is fixed to the telescopic member 2 or the support member 1 by bolts, welding or other means. The crossbar is a horizontally arranged rod connected between the columns to form a continuous protective barrier. The intermediate rod is an additional crossbar located between the columns to increase the protection strength and stability. The handrail is a crossbar at the top for workers to grasp and provide additional safety support. The footboard is installed on a vertical plate at the bottom of the railing, and the height can be 180 mm to prevent tools, materials and other items from falling from the edge and protect the safety of the people below. The mesh is made of metal mesh or nylon mesh, covering between the railings, providing more comprehensive protection and preventing small objects from penetrating the protection component 6. The mesh can be fixed or removable for easy maintenance and cleaning. The warning sign is a conspicuous warning sign installed on the protection component 6 to remind workers to pay attention to the danger of the edge and enhance safety awareness. The sign content may include words such as "No approach" and "Height work" and be accompanied by obvious colors (such as yellow, red) and patterns. The protective component 6 may also be equipped with a buffer device, such as an elastic rope or an airbag, to provide a buffer when a worker accidentally touches the protective component 6 and reduce the impact force. The protective component 6 may have an anti-slip design, such as adding an anti-slip strip or coating to the handrail to improve the stability of the grip. The protective component 6 may also be weather-resistant and use anti-corrosion and anti-ultraviolet materials to ensure that it will not age or deform during long-term use.

[0062] Compared with the prior art, the edge protection device provided by the present application cooperates the second end of the telescopic member 2 with the second clamping portion 3 of the support member 1, so that after the telescopic member 2 is extended, the first end of the telescopic member 2 can be installed on the first clamping portion 4, so that the protection component 6 connected to the telescopic member 2 is fixedly connected to the support member 1. The present disclosure adopts a mechanical connection method to fix the protection component 6 to the support member 1, thereby avoiding directly welding the guardrail uprights to the steel beam to damage the anti-corrosion coating.

[0063] like Figure 1 As shown, in some modified embodiments of the present application, the telescopic member 2 includes a first connecting member 23 and a second connecting member 21, the first connecting member 23 cooperates with the first clamping portion 4, and the second connecting member 21 cooperates with the second clamping portion 3; the first connecting member 23 and the second connecting member 21 are threadedly connected.

[0064] The first connecting member 23 cooperates with the first clamping portion 4 of the support member 1 and is located at one end of the telescopic member 2. The second connecting member 21 cooperates with the second clamping portion 3 of the support member 1 and is located at the other end of the telescopic member 2. The first connecting member 23 and the second connecting member 21 are connected by threads, and the length of the telescopic member 2 can be adjusted by rotation, and fixed in the desired position by a locking mechanism. The first connecting member 23 can be a tubular or rod-shaped structure with external threads, one end of which is designed with an interface that cooperates with the first clamping portion 4, and the external thread part is used to cooperate with the internal thread of the second connecting member 21. The second connecting member 21 is a tubular or rod-shaped structure with internal threads, one end of which is designed with an interface that cooperates with the second clamping portion 3, and the internal thread part is used to cooperate with the external thread of the first connecting member 23. The first connecting member 23 and the second connecting member 21 are screwed together by threads to form an integral body with adjustable length. By rotating the second connecting member 21, the length of the telescopic member 2 can be accurately adjusted to meet the needs of steel beams of different widths.

[0065] like Figure 1 As shown, in some modified embodiments of the present application, a locking structure 5 is provided between the first connecting member 23 and the second connecting member 21 , and the locking structure 5 is used to lock the positions of the first connecting member 23 and the second connecting member 21 .

[0066] In order to prevent the telescopic member 2 from accidentally extending and retracting during use, a locking mechanism is provided at the threaded connection, which can ensure that the telescopic member 2 can be firmly fixed after being adjusted to a suitable length, and will not loosen due to vibration or other external forces. Specifically, the locking mechanism can be a locking nut, which is used in conjunction with the first connecting member 23 and the second connecting member 21, and the threaded connection is locked by the friction between the locking nut and the two connecting members. More specifically, the locking nut can be provided between the first connecting member 23 and the second connecting member 21, and the first connecting member 23 and the second connecting member 21 respectively cooperate with the first clamping portion 4 and the second clamping portion 3 to achieve preliminary fixation, and the locking nut further presses the connecting member to prevent it from loosening. The locking nut has a simple structure, low cost, is easy to install and disassemble, is suitable for most conventional application scenarios, and provides a reliable anti-loosening effect.

[0067] The locking mechanism can be an anti-loosening washer, which can be divided into two types: spring washers and toothed washers. Spring washers have a certain elasticity and generate reaction force through deformation, increasing the friction between the nut and the bolt. The toothed washer has sharp teeth on the surface, which can bite into the nut and the supporting surface to form a mechanical lock. The toothed washer provides an additional anti-loosening effect, especially suitable for environments with large vibrations. It is easy to install, and only needs to install a washer under the connector. It is suitable for construction sites with large vibrations and harsh environments, such as bridges, high-rise buildings, etc.

[0068] The first connector 23 and the second connector 21 can also be connected by a self-locking thread. The self-locking thread has a high friction force after tightening to prevent loosening through special thread design (such as trapezoidal thread, multi-start thread, etc.) or material treatment (such as nylon insert, stainless steel, etc.). It has good self-locking performance and does not require additional anti-loosening devices. It is suitable for high-precision and high-load application scenarios, provides reliable anti-loosening effects, and is suitable for precision engineering with extremely high anti-loosening requirements, long-term use of protective facilities, etc.

[0069] The locking mechanism can be a stop pin. Specifically, a stop pin hole can be provided at the threaded connection. When the nut is tightened to a suitable position, the stop pin is inserted to fix the nut. The stop pin provides an absolute anti-loosening effect and completely prevents the nut from loosening. It is suitable for occasions that require long-term fixation, such as permanent protective facilities. It is suitable for permanent or long-term edge protection devices, such as building exterior walls, bridge railings, etc.

[0070] The locking mechanism can be a chemical anti-loosening agent. Specifically, a chemical anti-loosening agent (such as anaerobic glue) can be applied to the threaded connection between the first connector 23 and the second connector. After the glue is cured, a strong bonding layer is formed to prevent the nut from loosening. It provides a very strong anti-loosening effect and is suitable for long-term fixation in extreme environments. The installation is simple, just apply glue.

[0071] like Figure 1 As shown, in some modified embodiments of the first aspect of the present application, the locking structure 5 includes a first locking nut and a second locking nut, the first locking nut is in contact with the end surface of the first connecting member 23, and the second locking nut is in contact with the end surface of the second connecting member 21. This design ensures that the telescopic member 2 will not loosen or slide due to vibration or other external forces after being adjusted to a suitable length by means of double nut anti-loosening.

[0072] By rotating the second connecting member 21, the total length of the telescopic member 2 is adjusted to adapt to steel beams of different widths. When the telescopic member 2 is adjusted to a suitable length, the first locking nut and the second locking nut are tightened in sequence so that they are in close contact with the end faces of the first connecting member 23 and the second connecting member 21, respectively, thereby fixing the position of the telescopic member 2. Since the two locking nuts are in contact with the end faces of the connecting members, a double locking mechanism is formed, which effectively prevents the telescopic member 2 from loosening or sliding due to vibration or other external forces during use.

[0073] like Figure 1 As shown, in some modified embodiments of the present application, a first connection hole 24 is provided at the end of the first connection member 23, a second connection hole 22 is provided at the end of the second connection member 21, the first clamping portion 4 is inserted into the first connection hole 24, and the second clamping portion 3 is provided in the second connection hole 22. The first connection hole 24 is located at the end of the first connection member 23, and is used to insert the first clamping portion 4 on the support member 1. The second connection hole 22 is located at the end of the second connection member 21, and is used to insert the second clamping portion 3 on the support member 1.

[0074] Specifically, during installation, the end of the first connecting member 23 can be aligned with the first clamping portion 4 of the support member 1, and inserted into the first connecting hole 24. Ensure that the first clamping portion 4 is fully inserted and fixed in the first connecting hole 24. Then, by rotating the second connecting member 21, adjust the total length of the telescopic member 2 to adapt to the height of the steel beam. Align the end of the second connecting member 21 with the second clamping portion 3 of the support member 1, and insert it into the second connecting hole 22, ensuring that the second clamping portion 3 is fully inserted and fixed in the second connecting hole 22. When the telescopic member 2 is adjusted to a suitable length, use a locking nut or other locking mechanism to fix the first connecting member 23 and the second connecting member 21 to prevent accidental extension and retraction.

[0075] In some modified embodiments of the present application, the second connecting hole 22 and the second clamping part 3 are threadedly connected; the cross section of the first clamping part 4 is a polygon, and the first connecting hole 24 cooperates with the first clamping part 4. The second connecting hole 22 and the second clamping part 3 are threadedly connected, so that the second connecting hole 22 and the second clamping part 3 are threadedly connected together while the first connecting member 23 and the second connecting member 21 are rotated and extended, which ensures the connection strength of the second connecting hole 22 and the second clamping part 3 while facilitating installation. Specifically, the first clamping part 4 can be a polygonal columnar structure, such as a square column or a pentagonal column, etc. The first connecting hole 24 cooperates with the first clamping part 4 to facilitate the insertion of the first connecting member 23 on the first clamping part 4 and avoid the rotation of the protective component 6, thereby improving the stability of the threaded connection between the second connecting hole 22 and the second clamping part 3, thereby improving the stability of the connection between the telescopic member 2 and the support part.

[0076] like Figure 2 and Figure 3 As shown, in some modified embodiments of the present application, the protective assembly 6 includes a plurality of connecting rods 61, and the telescopic member 2 is provided with a plurality of connecting rods 61, and the plurality of connecting rods 61 are connected to the first connecting member 23 of the telescopic member 2. This design not only improves the overall stability and safety of the protective device, but also can adapt to more complex construction environments and variable steel beam layouts. The protective assembly 6 includes columns, crossbars, intermediate rods and diagonal braces. The vertically arranged pillars can be fixed to the telescopic member 2 or the support member 1 by bolts, welding or other means. The crossbar is a horizontally arranged rod connected between the columns to form a continuous protective barrier. The telescopic member 2 can also be arranged on the crossbar, for example, the crossbar is connected to the bottom end of the pillar to connect multiple pillars together, and the telescopic member 2 can also be arranged on the crossbar to fix and connect multiple pillars. The intermediate rod is an additional crossbar located between the pillars to increase the protective strength and stability. The diagonal braces are used to enhance the stability of the overall structure, especially in a larger protection area, where the diagonal braces can provide additional support to prevent structural deformation.

[0077] The connecting rod 61 and the telescopic member 2 can be fixed by high-strength bolts to ensure the firmness of the connection. The connecting rod 61 and the telescopic member 2 can also be quickly locked with a pin or a latch to facilitate installation and disassembly. A snap-on connector can be used between the connecting rod 61 and the telescopic member 2 to make the connection between the connecting rod 61 and the telescopic member 2 more convenient, which is suitable for construction sites that require frequent adjustments. The connecting rod 61 and the telescopic member 2 can be connected by welding to provide a very firm connection.

[0078] like Figure 2 and Figure 3As shown, the protection assembly 6 also includes a protection net 62, which is arranged between two adjacent connecting rods 61. Specifically, the protection net 62 can be a metal net, and commonly used materials include galvanized steel wire mesh, stainless steel mesh, etc., which have high strength and corrosion resistance and are suitable for long-term use and harsh environments. The protection net 62 can also be a nylon net, which is light and easy to install, suitable for temporary or highly mobile construction sites. The protection net 62 can also be a composite material net, which combines the advantages of metal nets and nylon nets, has high strength, lightness and weather resistance, and is suitable for a variety of application scenarios.

[0079] The protective net 62 may be provided with a metal frame around it for fixed connection with the connecting rod 61. According to the protection requirements, protective nets 62 with different mesh sizes can be selected. Smaller meshes can prevent small objects from penetrating, while larger meshes are more suitable for ventilation and clear vision. Hooks are provided on the frame of the protective net 62, which can be directly hung on the connecting rod 61 for quick installation and removal. The protective net 62 can also be fixed to the connecting rod 61 using ropes or straps, which is suitable for occasions that require a more secure connection. The protective net 62 can also be fixed to the connecting rod 61 by bolts to provide higher stability and safety.

[0080] The main function of the protective net 62 is to form a continuous protective barrier between two adjacent connecting rods 61 to prevent workers from approaching the dangerous edge from any angle. The protective net 62 can also prevent tools, materials and other items from falling from a height to protect the safety of people below.

[0081] The connecting rod 61 is connected to the first connecting member 23 of the telescopic member 2 so that the connecting rod 61 will not be extended or retracted along with the telescopic member 2, thereby facilitating adjustment of the telescopic length.

[0082] like Figure 2 and Figure 3As shown, in some modified implementations of the present application, an infrared alarm component 7 is also included, and the infrared alarm component 7 is arranged on the connecting rod 61. The infrared alarm component 7 may include an infrared sensor, an alarm, a controller and a power module. The infrared sensor is mounted on the connecting rod 61 and can detect the approach of a human body or an object. The infrared sensor generally includes a transmitter 71 and a receiver 72. When a person or an object enters the set detection range, the sensor triggers an alarm. The alarm is connected to the infrared sensor and can emit an audible and visual alarm when an abnormal situation is detected. The alarm can be a built-in buzzer or an externally connected tweeter, or it can be equipped with an LED (light-emitting diode) light bar to provide a visual warning. The controller is used to manage the working status of the infrared sensor and the alarm, and parameters such as the detection range, sensitivity, and delay time can be set. The controller can also be connected to other smart devices (such as surveillance cameras, mobile phone software) to achieve remote monitoring and management. The power module provides power support for the infrared alarm component 7. The power module can be battery-powered, solar-powered, or mains-powered, and the specific choice depends on the conditions of the construction site.

[0083] The infrared sensor and alarm can be fixed on the connecting rod 61 by a bracket or a clamp to ensure its stability and accuracy. The infrared alarm component 7 adopts a modular design and can be flexibly arranged according to actual needs, which is convenient for installation and maintenance. The infrared alarm component 7 can monitor the protection area in real time. When a person or object approaches the dangerous edge, an alarm will be immediately issued to remind the workers to pay attention to safety. The infrared alarm component 7 is combined with the physical protection net 62 to provide double protection and further improve safety. By connecting with smart devices, managers can monitor the status of the protection system in real time and promptly discover and deal with potential safety hazards.

[0084] like Figure 2 and Figure 3 As shown, in some modified embodiments of the present application, the infrared alarm assembly 7 includes a transmitter 71 and a receiver 72, and the transmitter 71 and the receiver 72 are respectively arranged at opposite ends of two adjacent connecting rods 61. This design can immediately issue an alarm when the protection net 62 or the protection fence is accidentally damaged or displaced through infrared detection technology, further improving the safety and reliability of the edge protection system.

[0085] like Figure 2 and Figure 3As shown, in some modified embodiments of the present application, the infrared alarm assembly 7 also includes a voice alarm device, a solar alarm lamp 73 and a controller, the voice alarm device is arranged in the accommodating space; the solar alarm lamp 73 is arranged on the top of the protective net 62; the voice alarm device, the receiver 72 and the solar alarm lamp 73 are connected to the controller. The transmitter 71 is installed at the end of one connecting rod 61, facing the opposite end of the other connecting rod 61. The main function of the transmitter 71 is to continuously emit infrared beams to form an invisible "protective barrier". When the infrared beam is blocked or interrupted, the transmitter 71 will immediately send a signal to the receiver 72 to trigger an alarm. The receiver 72 is installed at the opposite end of the other connecting rod 61, aligned with the transmitter 71, and is used to receive the infrared beam. Alarm module: When the receiver 72 detects that the infrared beam is blocked or interrupted, it will trigger an alarm device (such as an audible and visual alarm, a buzzer, etc.). The receiver 72 can communicate with the monitoring system or other safety equipment at the construction site through a communication interface to achieve remote monitoring and alarm. The main function of the receiver 72 is to monitor the status of the infrared beam in real time to ensure the integrity of the protection system. When the infrared beam is blocked or interrupted, the receiver 72 will immediately trigger an alarm to alert construction workers to potential safety hazards. The transmitter 71 and the receiver 72 can be fixed at opposite ends of two adjacent connecting rods 61 to ensure that the infrared beam can be accurately aligned. The transmitter 71 and the receiver 72 can also allow the angles of the transmitter 71 and the receiver 72 to be fine-tuned to adapt to different installation environments and protection requirements. In order to adapt to outdoor construction environments, the transmitter 71 and the receiver 72 can be equipped with waterproof and dustproof casings to ensure that they work normally in harsh environments.

[0086] The transmitter 71 continuously emits an infrared beam, and the receiver 72 monitors the status of the infrared beam in real time. When the infrared beam is not blocked or interrupted, the receiver 72 remains silent and the system is in normal working condition. When a person or object passes through the infrared beam, or the protective net 62 or the guardrail is accidentally damaged or displaced, the infrared beam will be blocked or interrupted. After the receiver 72 detects the interruption of the infrared beam, it immediately triggers the alarm module and sends out an audible and visual alarm signal. The alarm signal can be transmitted to the monitoring system at the construction site via wireless communication or wired communication to notify relevant personnel to take measures. When the infrared beam returns to normal, the receiver 72 will automatically reset and the alarm signal will stop. A manual reset function can also be provided to ensure that the alarm signal will not be triggered by mistake or last for a long time.

[0087] According to the actual construction environment and protection requirements, select the appropriate infrared beam emission distance and angle to ensure that the coverage of the protection system is large enough. For a larger protection area, multiple infrared alarm components 7 can be added to form a multi-layer protection barrier. Specifically, the transmitter 71 and the receiver 72 can be set at the diagonal of the protection net 62.

[0088] The solar alarm light 73 is arranged on the top of the protection net 62. This design further enhances the safety and visibility of the protection system, especially at night or under low visibility conditions, and can provide a more obvious warning effect. The solar alarm light 73 may include a solar panel, an LED light group, a power management system, an alarm module and a waterproof and dustproof housing. The solar panel is installed on the top or side of the alarm light to absorb solar energy and convert it into electrical energy to power the alarm light. The LED light group adopts a high-brightness LED light, which can emit strong light at night or under low visibility conditions to serve as a warning. The power management system includes a built-in lithium battery or other energy storage device to store solar energy collected during the day to ensure that the alarm light can still work normally at night or on cloudy days. When the infrared alarm component 7 is triggered, the solar alarm light 73 will start synchronously, and the alarm module will send out an audible and visual alarm signal (such as flashing lights, buzzers, etc.) to remind construction personnel to pay attention to potential safety hazards. Waterproof and dustproof housing In order to adapt to the outdoor construction environment, the solar alarm light 73 usually adopts a waterproof and dustproof design to ensure that it can work normally in harsh environments.

[0089] The main function of the solar warning light 73 is to provide lighting at night or in low visibility conditions, and to alert construction workers to dangerous areas through flashing lights or sound and light alarms. It can also automatically detect the intensity of ambient light through a photosensitive sensor, and automatically turn on the light when the light becomes dim, ensuring an all-weather warning effect. The solar warning light 73 can communicate with the monitoring system or other safety equipment at the construction site to achieve remote monitoring and alarm.

[0090] Example 2

[0091] A method for using an edge protection device comprises the following steps:

[0092] Install the first end of the telescopic member 2 in the contracted state on the first clamping portion 4 of the support member 1;

[0093] The telescopic member 2 is extended, and the second end of the telescopic member 2 is mounted on the second clamping portion 3 so that the protective assembly 6 connected to the telescopic member 2 is fixedly connected to the supporting member 1 .

[0094] Specifically, the structure of the edge protection device can be the same as that of Example 1, and will not be described in detail here. The method of use can be carried out according to the following steps:

[0095] S1: Install the first end of the telescopic member 2.

[0096] Specifically, align the first end of the telescopic member 2 with the first clamping portion 4 of the support member 1. If the first end of the telescopic member 2 is provided with a first connecting hole 24, insert the first clamping portion 4 into the first connecting hole 24 to ensure that it is fully fixed. Use bolts, pins or other locking mechanisms to firmly fix the first end of the telescopic member 2 to the support member 1 to ensure that it will not loosen. Confirm that the first end of the telescopic member 2 is firmly fixed to the support member 1 without any looseness or shaking. If there are multiple telescopic members 2, repeat the above steps to ensure that the first end of each telescopic member 2 is correctly installed.

[0097] S2: Adjust the length of telescopic member 2.

[0098] Specifically, according to actual needs, the second connecting member 21 of the telescopic member 2 is gradually rotated to gradually extend the telescopic member 2 from the contracted state. During the extension process, ensure that the movement of the telescopic member 2 is smooth without jamming or blocking. The length of the telescopic member 2 can be flexibly adjusted according to the actual width of the steel beam to ensure that it can adapt to different construction environments. The length of the telescopic member 2 should be moderate, neither too short to cause insufficient connection strength, nor too long to cause the protective component 6 to lose stability. If the length of the telescopic member 2 is not appropriate, it can be adjusted until the optimal state is reached.

[0099] S3: Lock the position of the telescopic member 2.

[0100] When the telescopic member 2 is adjusted to the appropriate length, use a locking nut or other locking mechanism to fix the position of the telescopic member 2 to prevent it from accidentally extending and retracting. Make sure the locking nut is tightened in place to prevent it from loosening during use. Confirm that all telescopic members 2 are firmly locked and will not loosen or slide due to vibration or other external forces. If there are multiple telescopic members 2, check the locking status of each telescopic member 2 one by one to ensure that all parts are properly fixed.

[0101] S4: Install the second end of the telescopic member 2.

[0102] Specifically, align the second end of the telescopic member 2 with the second clamping portion 3 of the support member 1. If the second end of the telescopic member 2 is provided with a second connecting hole 22, insert the second clamping portion 3 into the second connecting hole 22 to ensure that it is completely fixed. Use bolts, pins or other locking mechanisms to firmly fix the second end of the telescopic member 2 to the support member 1 to ensure that it will not loosen. Confirm that the second end of the telescopic member 2 is firmly fixed to the support member 1 without looseness or shaking. If there are multiple telescopic members 2, repeat the above steps to ensure that the second end of each telescopic member 2 is correctly installed.

[0103] S5: Fix the protection component 6.

[0104] Connect the connecting rod 61 to the telescopic part 2 by means of bolts, pins or snaps to form a complete protective frame. Ensure that the connection between the connecting rod 61 and the telescopic part 2 is firm to avoid loosening or falling off during use. Hang or fix the frame of the protective net 62 between two adjacent connecting rods 61 to ensure that the protective net 62 is firmly connected to the protective frame. If a hook-type installation method is used, ensure that the hook is firmly hung on the connecting rod 61; if a binding or bolt-type installation method is used, ensure that the rope or bolt is tightened in place. Confirm that all connecting rods 61 and protective nets 62 have been correctly installed and are not loose or damaged. If there is an infrared alarm component 7 or a solar alarm light 73, ensure that these devices are also correctly installed and in normal working condition.

[0105] Specifically, the protection component 6 may be directly assembled and connected to the first end of the telescopic member 2 before installing the first end of the telescopic member 2 , thereby facilitating the installation of the protection component 6 .

[0106] Compared with the prior art, the method for using the edge protection device provided by the present application is to cooperate the second end of the telescopic member 2 with the second clamping portion 3 of the support member 1, so that after the telescopic member 2 is extended, the first end of the telescopic member 2 can be installed on the first clamping portion 4, so that the protection component 6 connected to the telescopic member 2 is fixedly connected to the support member 1. The present disclosure adopts another firm connection method to fix the protection component 6 to the support member 1, thereby avoiding directly welding the guardrail uprights to the steel beam to damage the anti-corrosion coating.

[0107] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
