Description

Technical Field

[0001] This invention relates to an electrician's ladder, specifically a multi-functional electrician's ladder, belonging to the technical field of auxiliary equipment for electrical construction. Background Technology

[0002] Electricians often need to use ladders to perform tasks such as equipment installation, line maintenance, and lamp replacement. The traditional ladders currently in use (such as A-frame ladders and straight ladders) have limited functions and have the following significant drawbacks: (1) Inconvenient tool access: Existing ladders do not have a reasonable and safe platform or tool slot, so there is nowhere to put tools. Electricians need to frequently go up and down the ladder to retrieve tools such as screwdrivers, pliers, test pens, and tape, or risk operating with one hand, which is inefficient and poses a safety hazard; (2) Difficult to meet lighting needs: Existing ladders do not have lighting devices. In environments with insufficient light, such as inside the distribution cabinet, in the ceiling mezzanine, or during nighttime emergency repairs, additional hand lighting equipment is required, which occupies both hands or requires assistance from others, making operation inconvenient; (3) Small parts are easily lost: When electricians are operating, there is nowhere to fix small parts such as screws, nuts, wire caps, and terminals that need to be disassembled or installed. They are easily lost by rolling off the ladder, affecting work efficiency; (4) The stability and portability of the ladder are contradictory: Sturdy ladders are often heavy and not portable; lightweight ladders may lack stability. It is clear that current ladders have limited functionality, only providing the ability to climb, and cannot meet the comprehensive needs of complex electrical work scenarios.

[0003] The current patent CN205532237U multi-functional electrician's ladder has a foldable operating table and tool bag at the top, which can store tools and screws, etc. However, it is closable and deep, and there are many tools stored. When using it, you need to search for the required tools. The visibility is poor, and small tools such as screws are not easy to find, which wastes time and is inconvenient to operate.

[0004] Therefore, there is an urgent need for a new type of ladder that can solve the above problems and provide convenience, efficiency and safety for electricians working at heights. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-functional ladder for electrical work. The ladder has a simple structure, is easy to use, and integrates tool storage, auxiliary lighting, parts adsorption, high safety and easy handling.

[0006] To solve the above technical problems, the present invention provides a multi-functional climbing ladder for electrical work, including a ladder frame, on which a tool rack, a lighting component and an adsorption component are provided; The tool rack can be rotatably mounted on the top of the ladder rack. The tool rack has multiple round holes and slots, and hooks are installed in the round holes. The lighting component is a flexible LED light strip, which is installed below the top crossbeam of the ladder rack or on both sides of the ladder rack. The adsorption component is a magnetic adsorption strip.

[0007] The technical solution further defined in this invention is: Furthermore, in the aforementioned multi-functional climbing ladder for electrical work, the ladder frame is an A-frame or A-type ladder structure, and the ladder frame is composed of two main ladder frames. The upper ends of the two main ladder frames are hinged together, and the main ladder frame consists of an extendable upper ladder and a lower ladder. The upper ladder includes an upper ladder frame, with multiple steps horizontally spaced on the upper ladder frame. A slide bar is provided on the surface of the ladder frame along the length of the upper ladder frame, and multiple spring catches are provided on the slide bar perpendicular to the slide bar. The lower ladder includes a lower ladder frame with multiple steps horizontally spaced on the lower ladder frame. The lower ladder frame is a hollow sliding groove structure that is compatible with the sliding strip. A round hole is opened on the lower ladder frame to be compatible with the spring ball. The sliding strip moves in the lower ladder frame to form a sliding pair connection and is fixed by the spring ball and the round hole.

[0008] Technical advantages: The upper end of the ladder frame in this invention is hinged, making it easy to compress together. Combined with the telescopic ladder frame body, the ladder frame can be adjusted to its smallest size before being moved, making it more convenient. The ladder frame body is a telescopic structure. By setting a hollow lower ladder frame and sliding bars, the upper and lower ladders can slide up and down. Ultimately, the usable height of the ladder can be adjusted according to needs, making it highly adaptable. Spring ball bearings and round holes increase the stability of the upper and lower ladders.

[0009] In the aforementioned multi-functional ladder for electricians, a handle is provided in the middle of the upper ladder frame.

[0010] The technology makes it easy for workers to lift and move the equipment by hand when it is not on flat ground.

[0011] In the aforementioned multi-functional climbing ladder for electrical work, the bottom feet of the two lower ladder frames are each wrapped with an insulating sleeve to form four insulating feet.

[0012] Technical advantages: The invention wraps insulating sleeves around the bottom of the lower ladder frame, making installation and disassembly convenient, and also helps to solve the conductivity problem, ensuring personnel safety.

[0013] The aforementioned multi-functional climbing ladder for electrical work has a rubber insulation layer on the steps.

[0014] Technically, the rubber insulation layer installed on the ladder steps effectively insulates the area, ensuring the safety of operators while also providing some anti-slip properties.

[0015] In the aforementioned multi-functional ladder for electrical work, the tool rack is a ring or U-shaped frame, and the tool rack is connected to the top of the ladder frame through a universal swivel joint or a damping shaft.

[0016] Technical benefits: The invention features a ring or U-shaped design that facilitates rotation and easy selection of the required tools. The tool rack is connected to the ladder frame via an existing universal swivel joint, damping shaft, or other support components. This swivel connection allows the rack to rotate 360 ​​degrees in the horizontal plane and maintain its position at any angle, making it convenient for electricians to easily access and place tools in different working postures.

[0017] In the aforementioned multi-functional ladder for electrical work, a flexible LED light strip is connected to a rechargeable lithium battery and a switch. The battery is built into the upper ladder frame or steps, and the switch is located on the outside of the upper ladder frame.

[0018] The technical advantage lies in mounting the battery and switch on the main body of the ladder frame, making it convenient to use at any time and improving efficiency.

[0019] In the aforementioned multi-functional climbing ladder for electrical use, the magnetic adsorption strip is a strong magnetic rubber strip or a neodymium magnet strip.

[0020] The technical advantage is that one or more strong magnetic rubber strips or neodymium magnet strips are fixedly installed on the outside of the ladder frame or at an easily accessible location on the top crossbeam of the ladder rack. These strips are used to temporarily attract small metal parts and tools such as iron screws, nuts, washers, wire clamps, and electrician's blades, preventing them from rolling away and being lost. Compared to placing them in a tool bag, this makes them easier and faster to find.

[0021] In the aforementioned multi-functional ladder for electrical work, two casters are provided on the outer side of the lower ladder frame, and the casters are vertically installed on the lower ladder frame.

[0022] Technically, casters are installed on the outside of the lower ladder frame. On flat ground, the ladder can be tilted and pushed on the ground using the casters, saving labor and making it easy to use. On uneven ground, handles can be used for lifting and carrying.

[0023] In the aforementioned multi-functional climbing ladder for electrical engineering, the ladder frame is made of high-strength aluminum alloy or carbon fiber composite material; preferably, high-strength aluminum alloys such as 6061, 6063, and 7075 aluminum alloys are used; the carbon fiber composite material is a material composed of carbon fiber and epoxy resin.

[0024] Technical benefits: This invention uses high-strength lightweight materials (such as high-strength aluminum alloy and carbon fiber composite materials), which are sturdy, durable, corrosion-resistant, extremely lightweight, and have extremely high strength. It reduces the overall weight while ensuring load-bearing capacity (meeting safety standards, such as EN131 or GB / T 17889.1) and safety.

[0025] The beneficial effects of this invention are: (1) Significantly improve work efficiency: The rotatable tool rack is equipped with multiple hooks and slots. The slots use the existing elastic pull grooves to hang or hold common electrical tools such as screwdrivers, wrenches, pliers, test pens, and tape rings. This ensures that the tools are placed well on the tool rack and are not easy to fall off. They are clearly visible, easy to use, and efficient to select. This makes common tools readily available, reduces the number of times you have to go up and down ladders, and reduces the risk of one-handed operation. The magnetic strip makes it easy to pick up small parts, avoiding the time spent searching and picking them up. The integrated lighting frees up your hands and does not require additional lighting equipment or personnel assistance. (2) Enhance operational safety: Reduce unnecessary climbing and single-handed operation risks; good lighting reduces misoperation and visual fatigue; use sturdy materials and anti-slip design to ensure safety when climbing; small parts are adsorbed to prevent slippage and trampling risks; and an insulating sleeve is provided to avoid electrical conductivity risks.

[0026] (3) Highly integrated functions, multi-purpose: It integrates climbing, tool storage, parts storage and work lighting, adapting to the complex and ever-changing working environment of electricians (indoor distribution boxes, near outdoor utility poles, ceiling repair, nighttime emergency repair, etc.). (4) Portability and stability are both taken into account: Lightweight materials and optimized folding / telescopic design make it easy to carry and store, while the structural strength meets safety requirements; (5) Humanized design: Rotatable bracket, easy-to-access switch, and ergonomic design enhance the comfort of electricians; (6) Cost controllable: The main components are mature components (light strip, magnet, hook), the structure is reasonably modified, and it is easy to produce and promote.

However, the scope of protection of the present invention is not limited to the following embodiments. All other embodiments obtained by those skilled in the art based on the given embodiments without innovative effort are within the scope of protection of this application. Example 1

[0029] This embodiment provides a multi-functional climbing ladder for electrical use, see reference. Figure 1 As shown, a multi-functional ladder designed specifically for electricians working at heights, integrating multiple practical functions to improve work efficiency and safety, includes a ladder frame 1, on which a tool rack 2, a lighting component 3, and an adsorption component 4 are installed.

[0030] For details, please refer to Figure 2-3 As shown, the ladder frame 1 is a A-frame or A-type ladder structure, with a height of about 1.8 meters (the specifications can be adjusted as needed), and a load-bearing capacity of over 150 kg. The ladder frame 1 consists of two main ladder frames, with the upper ends of the two main ladder frames hinged together. The main ladder frame consists of an upper ladder 6 and a lower ladder 7 that can be extended and retracted. The upper ladder 6 includes an upper ladder frame 61, with multiple steps 8 horizontally spaced on the upper ladder frame 61. A slide bar 62 is provided on the surface of the ladder frame 61 along the length direction of the upper ladder frame 61. Multiple spring beads 63 perpendicular to the slide bar are provided on the slide bar 62. A handle 9 is provided in the middle of the upper ladder frame 61 to facilitate manual lifting and carrying by workers when transporting on non-flat ground. The lower ladder 7 includes a lower ladder frame 71, on which multiple steps 8 are horizontally spaced. Along its length, the lower ladder frame 71 has a hollow sliding groove structure. The lower ladder frame 71 is adapted to a sliding bar 62. A circular hole 73 is provided on the lower ladder frame 71 to accommodate a spring-loaded ball joint 63. The sliding bar 62 moves within the lower ladder frame 71, forming a sliding joint connection, and is fixed by the spring-loaded ball joint 63 and the circular hole 73. The bottom of the lower ladder frame 71 is covered with insulating sleeves to form four insulating feet. Easy to install and disassemble, and helps to solve the problem of electrical conductivity, ensuring personnel safety. Two casters 10 are provided on the outside of the lower ladder frame 71. The casters 10 are vertically set on the lower ladder frame 71. On flat ground, the ladder can be tilted and pushed on the ground by the casters, saving labor and making it easy to use. On uneven ground, the handle can be used to lift and move it. The ladder can be opened, closed and folded stably by the top hinge and the weight of the person standing on the ladder. After folding, it is compact and easy to put into the trunk of the engineering vehicle. The upper and lower ladder frames have rubber insulation layers on the steps 8, with embossed anti-slip surfaces. This effectively insulates and ensures the safety of operators while also providing some anti-slip protection.

[0031] It should be noted that the upper end of the ladder frame in this invention is hinged, which facilitates compression. Combined with the telescopic ladder frame body, the ladder frame can be adjusted to its minimum size before transport, making it more convenient. The ladder frame body is a telescopic structure. By setting a hollow lower ladder frame and sliding bars, the upper and lower ladders can slide up and down. Ultimately, the usable height of the ladder can be adjusted according to needs, making it highly adaptable. Spring ball bearings and round holes increase the stability of the upper and lower ladders. The ladder frame 1 is made of high-strength aluminum alloy or carbon fiber composite material, such as high-strength aluminum alloys like 6061, 6063, and 7075 aluminum alloys, or materials composed of carbon fiber and epoxy resin. It uses high-strength lightweight materials (such as high-strength aluminum alloy and carbon fiber composite material), making it sturdy, durable, corrosion-resistant, extremely lightweight, and extremely high-strength. It reduces the overall weight while ensuring load-bearing capacity (meeting safety standards, such as EN131 or GB / T17889.1) and safety.

[0032] For details, please refer to Figure 1 As shown, a ring-shaped stainless steel tool rack is installed above the top beam via an existing universal swivel joint with damping function. The tool rack has round holes of different diameters, with hooks such as S-hooks inside the holes, and a section designed with elastic silicone slots for fixing slender tools. The hooks and slots are used to hang or hold common electrical tools such as screwdrivers, wrenches, pliers, test pens, and tape rings. The swivel connection allows the rack to rotate 360 ​​degrees in the horizontal plane and maintain its position at any angle, making it convenient for electricians to pick up and put down tools in different working positions.

[0033] Specifically, the top crossbeam has a moderate width, and a lighting component 3 is embedded in its lower surface, with a length covering the crossbeam. The lighting component is a waterproof flexible LED light strip (IP65 protection level). The flexible LED light strip is connected to a 12V rechargeable lithium battery (capacity of 5000mAh or more) built into the cavity of the ladder frame. The switch is located on the outer side of the middle of the ladder frame.

[0034] It should be noted that one or more flexible LED light strips are embedded or securely attached along their length below the top crossbeam of the ladder frame or on the inner side of the ladder frame facing the work side. The flexible LED light strips are set in designated positions using 3M adhesive. The lighting assembly also includes, as needed, a controller for adjusting the brightness of the light, and a switch for controlling the opening and closing of the light strips. The connection sequence is as follows: battery, switch, controller, light strip. The LED light strips use commercially available and commonly used components, providing uniform and shadowless work lighting. Those skilled in the art can select commercially available conventional products to achieve the purpose of the invention based on the following parameters: It has an IP65 waterproof rating, meeting the waterproof and dustproof requirements for electrical work. The color temperature is 4000K-5000K, providing natural white light with uniform and shadowless illumination, and adjustable brightness. Use embedded or 3M adhesive to fix it to the designated position on the ladder frame; It is compatible with 12V, ≥5000mAh rechargeable lithium batteries.

[0035] Specifically, a strong magnetic rubber strip (with anti-slip texture) about 30cm long and 2cm wide is firmly attached to the outside of the upper ladder frame below the tool rack. This is used to temporarily hold small metal parts and tools such as iron screws, nuts, washers, wire clips, and electrician's blades, preventing them from rolling away and getting lost. Compared to placing them in a tool bag, this makes them easier and faster to find.

[0036] This invention overcomes the shortcomings of existing electrician ladders, such as limited functionality, inconvenient tool access, insufficient lighting, easy loss of small parts, and difficulty in balancing portability and sturdiness. It provides a multi-functional ladder that integrates tool storage, auxiliary lighting, parts adsorption, structural stability, and ease of transport. It can be widely used in fields such as building electricians, property maintenance, and power emergency repairs to improve maintenance efficiency and reduce tool wear and accident risks.

[0037] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
