Description

Technical Field

[0001] The utility model relates to the field of ball mill cleaning, in particular to an operating safety ladder. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are broken. This type of grinding machine is a machine that has a certain number of steel balls as grinding media in its cylinder.

[0003] It is widely used in cement, new building materials, fertilizers, black and non-ferrous metal beneficiation and other production industries, and can be used for dry or wet grinding of various ores and other grindable materials. Ball mills are suitable for grinding various ores and other materials, and are widely used in beneficiation, building materials and chemical industries. They can be divided into dry and wet grinding methods. According to different discharge methods, they can be divided into grid type and overflow type.

[0004] When flushing the ball mill outlet in the workshop, workers need to use ladders to enter the work area and set up safety ladders to increase the safety of workers when going up and down.

[0005] The patent with the published authorization announcement number CN211874364U discloses a climbing work ladder with safety belt protection, which includes a ladder body, the ladder body is provided with two and one end is hingedly connected, the ladder body includes an upwardly arranged support column, the support column is provided with two and is arranged in parallel with each other, a bottom connecting rod and a top connecting rod for connecting the two are provided between the two support columns, and a plurality of intermediate ladders for users to climb are provided between the bottom connecting rod and the top connecting rod, wherein a connecting ring is provided with a connecting ring on a movable sleeve on the connecting ring, and a safety belt is provided on the movable sleeve of the connecting ring, and the intermediate rung includes a rectangular tread block fixedly connected to the support column, the tread blocks are close to each other on a slide groove on one end face, a limit block matching with the tread block is provided in the slide groove, a limit spring is provided inside the slide groove, and a guide inclined surface is provided on one end face of the limit blocks close to each other, and the distance between the two guide inclined surfaces gradually decreases from the bottom connecting rod to the top connecting rod.

[0006] Regarding the above-mentioned utility model patent, we found that the utility model patent protects the workers by adding a safety belt. The safety belt is movably arranged on the ladder. When the worker climbs up, the safety belt can move upward in one direction synchronously, but the stability of the ladder body is not reinforced. Once the ladder collapses, the workers will fall and get injured together with the safety belt. In this patent, there are no components supporting each other between the ladder bodies, which makes the stability between the two groups of ladder bodies poor, and springs and other components are installed between the middle steps, which makes the stability effect at the middle stepping position worse, which makes it easy for the middle step to break when the workers step on it.
