[0027] The following are specific implementation cases and appendices. Figures 1-4The present invention will be further described below, but it is not limited to these embodiments. The present invention provides a technical solution: a detachable fire water tank maintenance ladder, comprising: a fire water tank body 1, a ladder connection and fixing assembly, an upper maintenance ladder assembly, and a lower maintenance ladder assembly. The ladder connection and fixing assembly is fixedly installed on the outer wall of the fire water tank body 1, and is located at the top of the outer wall. This position design facilitates operators to climb directly from the ground to the top of the water tank for maintenance work, while avoiding interference with other functional components of the water tank. The ladder connection and fixing assembly consists of two connecting rings 2 and a connecting plate 3. The two connecting rings 2 are fixed to the outer wall of the fire water tank body 1 by welding or bolting. Stainless steel is preferred to enhance corrosion resistance and structural strength. Its inner diameter is usually 50mm and the wall thickness is not less than 5mm to ensure a load-bearing capacity of not less than 200kg. The connecting plate 3 is movably fitted inside the two connecting rings 2 to form a detachable suspension mechanism. The connecting plate 3 is made of rectangular steel plate with a central perforation that fits the rings. The rolled edge design enhances rigidity, allowing for quick fixing by simply hanging it in during installation without additional tools. The upper maintenance ladder assembly is connected to the ladder connection and fixing assembly via an upper maintenance ladder rotating hinge 4. The hinge uses a stainless steel bearing structure, allowing the upper maintenance ladder assembly to be adjusted within the range of 0° to 180°, thereby adapting to different installation heights and inclined ground conditions of the fire water tank body 1. The lower maintenance ladder assembly is hinged to the upper maintenance ladder assembly via a lower maintenance ladder connecting shaft 6. The connecting shaft has a diameter of 20mm and is equipped with ball bearings, allowing the lower maintenance ladder assembly to rotate around the shaft and fold to the back of the upper maintenance ladder assembly. After folding, the overall thickness is reduced by more than 60%, greatly facilitating storage and transportation. The entire maintenance ladder adopts a modular design, with each component connected mechanically for quick assembly and disassembly, significantly improving the maintenance efficiency of fire water tanks.

[0028] As a preferred option, the upper maintenance ladder assembly is the core intermediate component connecting the ladder connection and fixing assembly and the lower maintenance ladder assembly. Its specific structure is as follows: two upper maintenance ladder rotating hinges 4 serve as key connecting parts, and are symmetrically arranged on the left and right sides of the outer wall of the connecting plate 3. The rotating hinges 4 preferably adopt a stainless steel bearing hinge structure, and their design must meet the requirements of strength and rigidity, and ensure smooth and easy movement with good wear resistance.

[0029] Two handrails 9 are installed on the outer wall of the upper maintenance ladder body 5. The handrails 9 are made of stainless steel tubes with a diameter of 30mm and a wall thickness of not less than 1.2mm, bent into shape, and their installation height is approximately 800mm to 900mm from the top surface of the ladder steps. The surface of the handrails 9 can be embossed or covered with a non-slip rubber layer to increase friction. The two ends of the handrails 9 are connected to the main uprights of the ladder body by welding or flanges to ensure that they can withstand a lateral tensile force of not less than 1000N.

[0030] As a preferred embodiment, the lower maintenance ladder assembly further includes: a lower maintenance ladder connecting shaft 6, which is movably disposed inside the upper maintenance ladder body 5 via bearings; a lower maintenance ladder body 7, which is movably disposed outside the lower maintenance ladder connecting shaft 6 via bearings; and the lower maintenance ladder body 7 can be folded with the upper maintenance ladder body 5 via the lower maintenance ladder connecting shaft 6; and a limiting baffle 8, which is fixedly disposed on the outer wall surface of the lower maintenance ladder body 7.

[0031] As a preferred embodiment, the lower maintenance ladder body 7 is further provided with two handrails 9 on its outer wall surface, two anti-slip sleeves 10 on its lower end, an NFC maintenance sticker 11 on its side wall surface, and a status reminder component on its side wall surface. The status reminder component includes: a card holder 12, which is located on the side wall surface of the lower maintenance ladder body 7; a status reminder window 13, which is located on the side wall surface of the lower maintenance ladder body 7; and four slots on the rear wall surface of the lower maintenance ladder body 7, with auxiliary support rods 14 movably mounted inside each of the four slots via shafts.

[0032] Working principle: When using this device, the operator first enters the relevant information into the NFC inspection sticker 11. When the operator uses the NFC reading module of the mobile phone to read the information in the NFC inspection sticker 11, the mobile phone browser will jump to the relevant webpage. Then the operator performs the operation by collecting the information and enters and registers the usage information of this device and the maintenance information of the fire water tank body 1.

[0033] When using this device, the operator takes it out of the warehouse and then lifts it to the area below the fire water tank body 1 that needs maintenance. Next, the operator unfolds the lower maintenance ladder connecting shaft 6, allowing the upper maintenance ladder body 5 to fit against the inner wall of the limiting baffle 8. At this point, the upper maintenance ladder body 5 and the lower maintenance ladder body 7 are in the same plane.

[0034] The operator hangs the connecting plate 3 inside the two connecting rings 2, so that the device is in a suspended state. Then, the operator reads the NFC inspection sticker 11 through the mobile phone and enters the inspection information. Then, the operator takes out the corresponding status card from the card wallet 12 and inserts it into the status reminder window 13, such as "Do not move this device during maintenance" to remind other staff not to move this device.

[0035] This device has two operating modes: vertical and inclined. In inclined mode, the two connecting rings 2 in the fire water tank body 1 are positioned below the ground, less than the extended length of the upper and lower maintenance ladder bodies 5 and 7. At this time, the lower maintenance ladder body 7 forms an angle of less than 90 degrees with the ground, and the anti-slip sleeve 10 is in contact with the ground, providing friction to ensure the operator's climbing safety. In vertical mode, the two connecting rings 2 in the fire water tank body 1 are positioned above the ground, greater than the extended length of the upper and lower maintenance ladder bodies 5 and 7. At this time, the lower maintenance ladder body 7 is perpendicular to the ground, and the anti-slip sleeve 10 cannot contact the ground. The operator then pulls out the auxiliary support rods 14 hidden in the upper and lower maintenance ladder bodies 5 and 7 respectively to support the fire water tank body 1, thus ensuring that the upper and lower maintenance ladder bodies 5 and 7 remain parallel to the fire water tank body 1.

[0036] Handrail 9 can assist operators in climbing.

[0037] Example: The ladder connection and fixing assembly includes two connecting rings 2 and a connecting plate 3. The connecting ring 2 is a U-shaped ring structure with an inner diameter of 50mm and a wall thickness of 5mm. It is made of stainless steel rods bent and welded, and the surface is polished to prevent scratches. The connecting plate 3 is a rectangular steel plate with a hole punched in the middle to mate with the ring 2, and rolled edges at both ends to enhance rigidity. During manufacturing, it is formed by die stamping to ensure a proper fit between the hole and the ring 2 (tolerance ±0.5mm). This assembly is fixed to the outer wall of the water tank body 1 via the rings 2. During installation, a level must be used to ensure that the two rings 2 are on the same horizontal line to prevent tilting when the maintenance ladder is suspended.

[0038] The upper maintenance ladder assembly consists of an upper maintenance ladder hinge 4, an upper maintenance ladder body 5, a handrail 9, and an auxiliary support rod 14. The upper maintenance ladder body 5 adopts a rectangular steel tube frame structure, with the main uprights made of 25×25×1.5mm stainless steel square tubing. The hinge 4 uses a stainless steel bearing hinge, allowing the ladder to rotate 0-180° around its axis; the hinge is lubricated internally to ensure smooth rotation. The handrail 9 is a 30mm diameter stainless steel tube, bent and welded to both sides of the ladder body. The auxiliary support rod 14 is concealed in a groove on the back of the ladder body, employing a hidden hinge design. When unfolded, it can be fixed with a locking pin, providing additional support in the vertical position.

[0039] The lower maintenance ladder assembly includes a lower maintenance ladder connecting shaft 6, a lower maintenance ladder body 7, a limiting baffle 8, an anti-slip sleeve 10, and a status reminder component. The lower maintenance ladder body 7 has a similar structure to the upper ladder, but is shorter for easier folding. The connecting shaft 6 is a 20mm diameter stainless steel shaft connected to the upper ladder body 5 via ball bearings, allowing the lower ladder to rotate around the shaft for folding. The limiting baffle 8 is a triangular steel plate welded to the lower ladder body 7 near the shaft. When the ladder is unfolded, the baffle 8 contacts the upper ladder body 5, forming a 90° limit to prevent over-unfolding. The anti-slip sleeve 10 is made of wear-resistant silicone material and is fitted onto the bottom of the lower ladder, with embedded corrugations to enhance friction. The status reminder component includes a card holder 12 and a status reminder window 13. The card holder is a waterproof plastic box for storing status cards; the status reminder window is a transparent acrylic window with internal card slots for easy insertion of status cards.

[0040] During production or initial activation, data is written to the tag using an NFC writer (such as a mobile app), including: ladder number, production date, maximum load capacity, and a link to the maintenance procedure. The data format is JSON, for example, "device_id":"T001","type":"inspection_ladder","manual_url":"https: / / example.com / t001". The tag has a storage capacity of 1KB, which is sufficient to hold text information.

[0041] In the field usage phase: Operators use NFC-enabled mobile phones to bring their phones close to tag 11 (distance <10cm). The phone automatically reads the tag ID and triggers the following control logic: The mobile browser redirects to a preset webpage (such as an enterprise maintenance management system), displaying ladder information, maintenance history forms, and operation guidelines. The system automatically records maintenance time, personnel ID, and geographical location (via mobile phone GPS) for data traceability. After personnel fill in the current maintenance status (e.g., "Start Maintenance" or "Complete Maintenance"), the data is uploaded to the cloud database via 4G / 5G network.

[0042] Error handling logic: If reading fails, the system prompts for a retry; if the label is damaged, data can be entered by scanning the QR code in the status reminder window 13.
