Movable anti-falling assembly, movable anti-falling crawling ladder and protection method thereof

Abstract

The invention relates to a movable anti-falling assembly, a movable anti-falling crawling ladder and a protection method thereof. The movable anti-falling assembly is characterized in that the movableanti-falling assembly is arranged on the crawling ladder and comprises a falling protector, a falling protector left-right movement adjusting assembly and a falling protector up-down movement adjusting assembly. The movable anti-falling crawling ladder has the beneficial effects that based on the purpose of maintaining the personal safety of loading and unloading workers, compared with a traditional fixed lifeline, the movable height-adjustable climbing ladder with the anti-falling protection structure is more flexible in operation, and free of space limitation, the height adjusting range ofthe crawling ladder is 3 meters to 4.5 meters, and the crawling ladder is suitable for most transport vehicles.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a mobile fall-prevention component, a mobile fall-prevention ladder and a protection method thereof. Background technique [0002] In the existing production sites, large tankers or trucks are common means of transportation. Since the feeding and discharging ports of large tankers or trucks are often located on the top of the tanker or truck, during the loading and unloading process of the truck, the loading and unloading staff often need to pass through the In traditional and simple climbing operations, the personal safety of loading and unloading workers is particularly important because the height ranges from 3 meters to 4.5 meters. As domestic enterprises pay more and more attention to safety, there are many hidden dangers in the original roof operation. [0003] For the purpose of maintaining the personal safety of loading and unloading workers, existing prod...

AI Technical Summary

Problems solved by technology

[0004] 1. To install the lifeline, since the installation area is fixed, the factory needs site planning and approval, and the procedure is cumbersome;

[0005] 2. Since the installation position of the lifeline is fixed, it can only be operated in a fixed area, which has relatively large limitations;

[0006] 3. The lifeline is installed on the top of the work area, and the manufacturing cost, design cost and other costs are relatively high;

[0007] 4. Due to the fixed installation position, the lifeline can only solve the protection of the roof operation, and has not yet provided effective protection when climbing up and down;

[0008] 5. The original climbing operation needs to climb to the roof of the car by climbing the car or climb to the roof of the car with the help of other climbing ladders. The first method of direct climbing is very risky; the second method of using other climbing ladders will have two problems:

[0009] 1) The height of the car is different, and climbing ladders of various heights are required, which will greatly reduce storage space, procurement costs and operating efficiency;

[0010] 2) If the vehicle coming is a tanker with an oval roof, there will be a gap between the climbing ladder and the roof of the tanker, and people cannot pass through it.

[0011] To sum up, since the existing climbing ladder used in conjunction with the lifeline, the overall structure is still the traditional ladder structure, that is, it only solves the function of climbing, and there is no special anti-fall protection structure. Therefore, this technical problem needs to be solved urgently, and a improved ladder
