[0002] Regular inspection and maintenance of bridges are essential to ensure their long-term stability. Under-beam inspection, as a crucial part of the inspection process, requires specialized equipment for high-altitude operations. Existing equipment for under-beam inspection mainly includes fixed ladders and suspended platforms.

[0003] However, the height of fixed ladders is not adjustable, requiring customization based on bridge height, resulting in equipment redundancy, high transportation costs, and difficulty in adapting to the inspection needs of bridge groups with large span differences. While suspended platforms can cover a larger working area, they rely on external power systems (such as winches), are complex to install, and are limited by the space around the bridge, making them extremely unsuitable for narrow or complex terrain.

[0004] In addition, traditional equipment such as those mentioned above lacks stability design and is easily affected by wind or mechanical vibration during operation, causing it to shake or even overturn, resulting in insufficient safety protection.

[0005] Therefore, there is an urgent need for an inspection ladder that integrates rapid adjustment, modular design, and multiple safety protections. Utility Model Content

Figure 2 This is a schematic diagram of the telescopic frame of the inspection ladder provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the working platform of the inspection ladder provided in this embodiment of the utility model.

[0027] like Figure 1 As shown, the inspection ladder provided in this embodiment of the present invention includes:

[0028] The telescopic frame 100 includes at least two slidably connected frame units 101. Each frame unit 101 includes a pair of uprights connected by a foot pedal 102. The uprights are provided with locking members, and adjacent frame units 101 are fixed together by locking members.

[0029] The work platform 200 is hinged to the first end of the telescopic frame 100. The work platform 200 includes at least two step plates 201, which are detachably connected to each other.

[0030] The clamp includes an upper clamp 301 and a lower clamp 302. The upper clamp 301 is disposed at the second end of the telescopic frame 100, and the first end of the telescopic frame 100 is adapted to be fixed to the beam by the upper clamp 301. The lower clamp 302 is disposed on the working platform 200, and the working platform 200 is adapted to be fixed to the pier by the lower clamp 302.

[0031] The inspection ladder body includes a multi-stage telescopic frame 100, which consists of uprights and horizontal steps 102. The inner side of the uprights is provided with guide grooves, and the height can be adjusted through the telescopic mechanism. It is equipped with a locking system, such as a bolt.

[0032] The telescopic frame 100 adopts at least two-stage telescopic structure. Each stage of the column achieves smooth telescopic extension and retraction through bearing assembly. The locking pin holes are distributed at preset intervals along the length of the column. The pedal 102 adopts an anti-slip design.

[0033] The multi-stage telescopic structure significantly reduces the storage volume while ensuring load-bearing strength. The guide groove and bearing assembly work together to ensure stability during the telescopic process, and the pin system provides multi-stage safety locking, achieving safe and efficient telescopic adjustment.

[0034] The work platform 200 includes at least two hinged step plates 201 connected by, for example, hinged hinges, forming a quick-folding mechanism. The step plates 201 remain fixed to each other in the folded state and form a continuous working surface when unfolded.

[0035] In one embodiment, the work platform 200 unfolds to form a 1.2m × 0.8m work area, with a load-bearing capacity of ≥800kg.

[0036] The top and bottom of the ladder are equipped with adaptive clamps, which are compatible with bolts and pins 501 and can be equipped with a pressure feedback adjustment mechanism. This dual fixing mechanism can significantly improve the system's anti-overturning ability.

[0037] According to one embodiment of the present invention, the inspection ladder further includes a safety component, which includes an anti-fall slide rail 400 disposed at the first end of the telescopic frame 100 and a hanging point slider disposed on the anti-fall slide rail 400.

[0038] like Figure 1 and 2 As shown, the top of the inspection ladder is equipped with a fall-prevention rail 400, featuring a sliding attachment point with a self-locking function, forming a dual protection link with the safety belt system. In one embodiment, the attachment point slider has a built-in trigger-type braking mechanism, and the safety belt connector can be equipped with a universal adjustment interface and redundant suspension nodes.

[0039] The above design enables full fall protection, triggers the braking mechanism to respond quickly in the moment of weightlessness, and the universal connector ensures the operator's freedom of movement, thus better protecting the operator's safety.

[0040] According to one embodiment of the present invention, the pedals 102 are spaced apart along the length of the column and the distance between two adjacent pedals 102 is equal.

[0041] According to one embodiment of the present invention, the locking member is located in the extending direction of the pedal 102, and the locking member includes a pin hole disposed in the column and a pin inserted into the pin hole.

[0042] The pedals 102 of the telescopic frame 100 are equidistantly arranged along the axial direction of the column, and locking components are integrated into the extending direction of the pedals 102. In one embodiment, the spacing of the pedals 102 is set according to ergonomics, and the axis of the pin hole of the locking component coincides with the longitudinal centerline of the pedal 102. When the pin passes through multiple levels of the frame, it simultaneously locks the position of the pedals 102. By optimizing climbing efficiency through equidistant distribution, the locking mechanism reduces individual operation steps, avoids the risk of structural instability caused by missing pedals 102, and improves overall safety and ease of operation.

[0043] According to one embodiment of the present invention, a magnetic latch 202 is provided on the step plate 201, and when two adjacent step plates 201 are folded, the two adjacent step plates 201 are suitable for locking by the magnetic latch 202.

[0044] According to one embodiment of the present invention, the work platform 200 includes a platform body, and the step plate 201 is detachably connected to the platform body.

[0045] like Figure 3 As shown, magnetic latches 202 are provided at the four corners of the step plate 201. The work platform 200 keeps the step plates 201 locked together in the folded state by means of the magnetic latches 202, and forms a continuous working surface when unfolded. The magnetic latches 202 can realize quick folding and self-locking, and the overall structure takes into account both storage convenience and work space expansion.

[0046] In addition, the telescopic frame 100, the working platform 200, and the clamps are all connected to each other via pins 501 and equipped with angle locking devices to achieve adaptive adjustment of the tilt angle between the telescopic frame 100 and the working platform 200. In one embodiment, the pin 501 has a built-in damping bearing, and the angle locking device adopts a ratchet-buckle composite structure. The damping bearing can eliminate the shaking of the working platform 200 and the inspection ladder body, and the angle locking device can achieve multi-angle adjustment and instantaneous locking, making the inspection ladder adaptable to the working angle requirements under different inspection conditions.

[0047] According to one embodiment of the present invention, the edge of the work platform 200 is provided with at least one of a guardrail 203 and a handrail.

[0048] The working platform 200 is equipped with a detachable guardrail 203 at its edge. The guardrail 203 adopts a plug-in connection, which can improve the efficiency of disassembly and assembly. In one embodiment, the height of the guardrail 203 is 1.2m.

[0049] According to one embodiment of the present invention, the inspection ladder further includes an embedded part 600, which is embedded in the beam and the pier. The upper clamp 301 is detachably connected to the embedded part 600 embedded in the beam, and the lower clamp 302 is detachably connected to the embedded part 600 embedded in the pier.

[0050] The embedded parts 600 between the beam and the pier are standardized interface components, and the clamps of the inspection ladder can be equipped with multi-specification adapter modules to achieve rapid coupling between the embedded parts 600 and the clamps. Standardized embedded interfaces reduce construction complexity, expand the applicability of the equipment, and reduce maintenance frequency. In one embodiment, the embedded part 600 can be a U-shaped embedded part.

[0051] According to one embodiment of the present invention, the bottom of the working platform 200 is provided with a retractable support rib 700, which supports the working platform 200 between the bridge pier and the bridge pier.

[0052] The bottom of the work platform 200 is equipped with a retractable support rib 700, forming a compensating support system for the contact surface between the work platform 200 and the bridge pier. The support rib 700 can ensure the uniformity of stress on the work platform 200 and ensure operational safety.

[0053] According to one embodiment of the present invention, the telescopic frame 100 and the working platform 200 are made of lightweight and high-strength metal materials.

[0054] In this embodiment of the utility model, no specific improvements are made to the materials of the telescopic frame 100 and the working platform 200. That is, the materials of the telescopic frame 100 and the working platform 200 are both made of materials that are lightweight and have high strength in the prior art, such as magnesium-aluminum alloy, aluminum-lithium alloy, magnesium alloy, etc.

[0055] In one embodiment, the telescopic frame 100 and the work platform 200 may also adopt a hybrid structure, for example, that of magnesium-aluminum alloy and carbon fiber reinforced composite material, with key load-bearing nodes being additively reinforced. Such a design can achieve an optimal balance between strength and weight.

[0056] In summary, the inspection ladder provided by this utility model adopts an innovative modular design concept. By decomposing the telescopic frame and working platform into multiple standardized functional units, it achieves rapid disassembly and flexible combination of the equipment. The telescopic frame adopts a nested structure design, and each frame unit is quickly connected through a locking mechanism; the working platform adopts a combination of foldable steps and detachable guardrails, which greatly improves on-site assembly efficiency. This modular design significantly shortens the overall installation time and is particularly suitable for bridge inspection operations that require frequent site changes.

[0057] The safety protection component is another core element of this invention, constructing a dual safety guarantee mechanism by integrating a fall-prevention slide rail and a self-locking fixing device. The fall-prevention slide rail is arranged along the top of the inspection ladder and equipped with a fast-response self-locking slider. Simultaneously, the upper and lower clamps employ a redundant fixing point design. This protection system significantly reduces the risk of accidents during high-altitude operations. Combined with a multi-directional safety belt system, it provides comprehensive safety protection for inspection personnel, effectively solving the technical problems of poor stability and insufficient protection in traditional inspection ladders.

[0058] In terms of material selection, this utility model adopts a lightweight and high-strength composite material system, which achieves significant weight reduction while ensuring structural strength, and also ensures the portability of the overall equipment, significantly reducing the difficulty of transportation and on-site relocation.

[0059] Therefore, the inspection ladder provided by this utility model can be quickly assembled and disassembled through the modular design of the telescopic frame and the working platform, which greatly reduces the installation time compared with traditional equipment; the safety is improved and the occurrence of safety accidents is reduced by integrating anti-fall slide rails and self-locking fixing devices into the protective components; in addition, the telescopic frame and the working platform are made of lightweight materials, which significantly reduces the weight of the equipment, making it easy to transport and assemble and disassemble, and significantly improving construction efficiency.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
