TECHNICAL FIELD

[0001] The utility model relates to the field of ladder, concretely to a modular anti-falling straight ladder. BACKGROUND

[0002] The straight ladder in the cold box is a vertical passing facility specially designed for the cold storage environment, which is made of steel, stable in structure, and has special properties such as cold resistance, anti-skid and corrosion resistance to ensure safe use in low temperature environment.

However, the traditional straight ladder has many deficiencies in design, especially in safety and comfort, which has been difficult to meet the current complex and changing operation requirements. In terms of comfort, the traditional straight ladder usually does not set a rest platform, and the user uses a step-by-step hanging climbing method with a safety belt, which cannot provide sufficient rest for the operator during climbing, and is prone to fatigue and discomfort. There is no anti-falling track, which affects the work efficiency and operation quality. SUMMARY

[0004] Therefore, the utility model aims to provide a modular anti-falling straight ladder to solve the technical problem of poor safety and comfort of the existing straight ladder in the cold box.

[0006] By adopting the above technical scheme, the combination design of the anti-falling slide and the ladder realizes the integration of climbing and anti-falling function. The ladders arranged staggeredly on both sides of the anti-falling slide not only facilitate the operator to climb flexibly at different heights, but also improve the space utilization. At the same time, the steel grating platform plate arranged below the ladder provides a spacious rest area for the operator, effectively relieving the fatigue caused by long-time climbing.

[0007] Further, the cross section of the anti-falling slide is in "C" type structure, and the anti-falling slide abuts against the rollers and the friction blocks.

[0009] Further, the two groups of rollers and the two groups of friction blocks are arranged in a rectangular shape and are installed in a diagonal structure, and the surface of the movable piece is provided with a hanging hole for hanging a lock.

[0010] By adopting the above technical scheme, the layout makes the anti-falling mechanism more evenly distribute pressure when subjected to external force, improves its carrying capacity and impact resistance, at the same time, the hanging hole opened on the surface of the movable piece provides convenience for the hanging of the lock and the anti-falling device, so that the anti-falling mechanism can be firmly locked on the anti-falling slide when needed.

[0011] Further, the upper outer side of the steel grating platform plate is welded and fixed with a platform railing, and the platform railing is a one-side opening mechanism to form a channel for operators to access the steel grating platform plate.

[0012] By adopting the above technical scheme, the platform railing provides a safe and reliable access channel for operators, effectively preventing falling accidents that may occur during climbing, and the platform railing is a one-side opening mechanism, which facilitates the entry and exit of operators and ensures the closed nature of the platform area, avoiding the risk of accidental falling of sundries or personnel.

[0013] Further, two groups of platform diagonal braces are welded and fixed between the lower side of the steel grating platform plate and the ladder.

[0014] By adopting the above technical scheme, the two groups of platform diagonal braces provide a solid support and stable foundation for the platform, effectively enhancing the carrying capacity and anti-deformation performance of the platform, and the reasonable layout and solid structure of the platform diagonal braces enable the platform to remain stable and not deformed when bearing the weight of multiple people standing or heavy objects placed at the same time, ensuring the safety of operators and the normal operation.

[0015] Further, the anti-falling slide is formed by splicing several slide sections through connecting pieces, and is arranged in a detachable structure.

[0016] By adopting the above technical scheme, the connecting pieces enable the ladder modules to be firmly connected together to form a whole structure, and the connecting pieces are fixed by high-strength bolts or welding, etc., to ensure that they do not loosen or fall off during climbing, so that the ladder can be flexibly combined and installed according to different height and structure requirements to form a ladder of the required length.

[0017] Further, the ladder is formed by welding several horizontal tread bars and longitudinal support vertical rods.

[0018] By adopting the above technical scheme, the longitudinal support vertical rods are made of high-strength low-temperature resistant material, which has excellent compression resistance, bending resistance and low-temperature resistance, and can effectively withstand the weight of the operator and the impact force during climbing.

DETAILED DESCRIPTION

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0028] A modular fall-proof straight ladder, such as Figures 1-4 As shown, the device includes a fall arrest slide 1 and ladders 2. Several ladders 2 are arranged alternately on both sides of the fall arrest slide 1. A steel grating platform 3 is welded and installed below each ladder 2 and between adjacent sets of ladders 2, providing a rest area for operators. Several fall arrest mechanisms 5 are slidably installed on the inner side of the fall arrest slide 1. Each fall arrest mechanism 5 includes a movable plate 501. Two sets of rollers 503 are rotatably installed on both sides of the movable plate 501, and two sets of friction blocks 504 are fixedly installed. The combined design of the fall arrest slide 1 and ladders 2 achieves both climbing and fall arrest functions. The integrated anti-fall slide 1 features staggered ladders 2 on both sides, which not only facilitates flexible climbing by operators at different heights but also improves space utilization. Meanwhile, the steel grating platform 3 installed below the ladders 2 provides operators with a spacious rest area, effectively alleviating fatigue caused by prolonged climbing. The anti-fall mechanism 5, which is slidably installed inside the anti-fall slide 1, includes a movable plate 501 and rollers 503 and friction blocks 504 on both sides, ensuring the sensitivity and reliability of the anti-fall system and providing strong protection for the safety of operators.

[0029] See Figure 1 , Figure 4 The anti-fall slide 1 has a "C" shaped cross-section. The anti-fall slide 1 abuts against the roller 503 and the friction block 504, making the contact between the slide friction block 504 tighter and enhancing the stability and guidance of the anti-fall mechanism 5 in the slide. At the same time, when it is necessary to adjust the position of the movable piece 501 by sliding, the movable piece 501 needs to be lifted upward, causing the roller 503 to abut against the anti-fall slide 1, thereby forming a sliding condition between the movable piece 501 and the anti-fall slide 1.

[0030] See Figure 2 , Figure 4The two groups of rollers 503 and the two groups of friction blocks 504 are arranged in a rectangular shape and are installed in a diagonal structure. The surface of the movable piece 501 is provided with a hanging hole 502 for hanging a padlock from the outside. This arrangement enables the anti-falling mechanism 5 to distribute pressure more evenly when subjected to external force, thereby improving its load capacity and impact resistance. Meanwhile, the hanging hole 502 provided on the surface of the movable piece 501 facilitates the hanging of a padlock and an anti-falling device from the outside, so that the anti-falling mechanism 5 can be securely locked on the anti-falling slide 1 when needed, preventing the anti-falling mechanism 5 from falling off or failing due to accidental circumstances. This not only enhances the reliability and safety of the anti-falling system, but also improves its flexibility and convenience in use. Embodiment 2:
