　　Single pillar anti collapse device Single pillar interlocking anti collapse device Steel connecting rod hard connection

　　Safe gold is hard to buy, fate is its own master,Single pillar anti collapse deviceEnsuring stability like a mountain,Single pillar chain anti collapse device steel connecting rodReliable anti slip, safe road runs every day, and safety production must rely on safety science and technology.

　　1Single pillar anti collapse deviceIntroduction:

　　The unloading and tilting of individual hydraulic supports caused by pressure relief or other reasons often occur underground in coal mines. In the existing technology, the working faceSingle pillar anti collapse deviceThe commonly used anti fall chains and nylon ropes to tie the column heads are difficult to operate, have poor fastening, and have a low safety factor. Once the pillar tilts, it may slide and cause injury accidents, which cannot achieve effective anti fall effects and cannot meet the needs of mine safety production. To overcome the shortcomings of existing technology, the purpose of this utility model is to provide a single hydraulic pillar interlocking anti collapse device, which can effectively solve the safety hazards of the existing coal mine hydraulic pillars due to their inconvenient use and poor performance.

　　This product is a top cutting pillar anti overturning and anti slip device used in underground coal mining working faces. The device includes two steel connecting rods. The upper and lower ends of the top cutting pillar cylinder body are fixed with steel clamps, and one end of the steel connecting rod is connected to the steel clamps through a pin shaft,Single pillar chain anti collapse device steel connecting rodThe other end is fixed to a row of individual pillars adjacent to the top cutting pillar through a pin connection. It can enable the top cutting pillar to be used independently on high angle working surfaces, with unlimited movement steps and convenient operation, improving work efficiency. Reduced requirements for usage environmental conditions. Reusable, anti fall, anti slip, safe and reliable.

　　4Single pillar anti collapse deviceExamples of necessity:

　　Taking the 11011 working face of Zhaogu Second Mine in Jiaozuo Coal Industry (Group) as an example, the length of the roadway is over 2200m, and the number of individual pillars in both tunnels can reach 7000-8000. Although such a large number of individual pillars can effectively support the roadway and prevent the bottom bulge and roof sinking, they may also be damaged due to aging and damage of various components of the individual pillars, unintentional collisions during external construction, or sudden increase in roadway pressure. On the other hand, the currently used individual pillars are generally high (3.15 meters), and the gravity is large when the individual pillars suddenly fall. Traditional anti fall facilities such as anti fall chains have problems with chain strength, anti fall hook strength, and unreasonable hanging. Unable to effectively prevent collapse, causing significant safety hazards and posing a threat to the safety management of construction personnel and equipment. There is a single hydraulic prop protection device calledSingle pillar anti collapse deviceThe connection structure between the single hydraulic support column of the coal mining face support equipment and the support top beam adopts a single column anti overturning and anti slip device.Single pillar chain anti collapse device steel connecting rodThe connection is simple, and the support angle of the pillar matches well with the angle of attack of the mine. A single column anti collapse and anti slip device is used to support the top beam, ensuring its safety. Simply put, it is a type of hard connection, with a hard connecting rod in the middle that can be adjusted from 80-140mm. The two ends are composed of semi-circular snap rings, locking square rings, and hand plate locks. The structure is simple and easy to install. The requirement to pull independent pillars.

　　Safety knowledge should be known,Single pillar anti collapse deviceBe well prepared, pay attention to underground work, and be happy in peace and safety,Steel connecting rod for anti collapse device of mining single pillarConnect safely, for the sake of family and loved ones. Shandong Hongyi looks forward to your inquiry.
