　　The market is the direction of the enterprise, we doSingle pillar anti collapse device for coal minesPrioritize product quality over price, only with quality can there be a market, and improveSingle pillar anti collapse device for coal minesThis product has made progress.Anti fall deviceBelow is a detailed introduction, welcome to learn more.

　　Single pillar anti collapse device for coal minesFunction:

　　Single pillar anti collapse device for coal minesStructure: Each anti fall device consists of two flower basket screws and two clamps, which are tightly fastened to adjacent columns and connected by two blue screw hooks in the middle.

　　Practicality analysis: When anti fall devices are used to connect columns, it transforms the single point-to-point connection into a face-to-face connection, from a single support to a related overall support. At the same time, it plays a "double" role for each column, even if the left side of the column is loose, its right side will tightly reinforce it, playing a safe role. The anti collapse device is also equivalent to adding an integral crossbeam to the entire surface of the advanced support, making the advanced pillar surface more stable and reliable.

　　Single pillar anti collapse device for coal minesCharacteristics:

　　Successfully solved the long-standing problem of pillar collapse prevention in single pillar working faces.

　　After adopting a double hook anti overturning device for all pillars of the single pillar working face, it is more reliable than using a single hook anti overturning device in the past, greatly improving the safety of the single pillar working face.

　　Using steel chains instead of steel wire ropes and nylon ropes is more convenient and safe to operate.

　　Four pairs of double hook anti fall devices are drilled with anti fall holes at the corresponding positions of the beam flower, achieving closed management of anti fall and standardizing the hanging position of the anti fall chain.

　　Single pillar anti collapse device for coal minesUsage: One end of the anti fall clip is clamped onto the metal top beam, and the other end is connected to a single pillar; Used for internal injection type single hydraulic prop, external injection type single hydraulic prop, suspended single hydraulic prop, with guaranteed product quality

　　This product is an anti overturning and anti slip device for cutting top pillars used in underground coal mining working faces. The device includes two steel connecting rods, with a steel buckle fixed to the upper and lower ends of the cutting top pillar cylinder body. One end of the steel connecting rod is connected to the steel buckle through a pin shaft, and the other end of the steel connecting rod is fixed to a row of individual pillars adjacent to the cutting top pillar through a pin shaft 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 overturning, anti slip, safe and reliable

　　Single pillar anti collapse device for coal minesUsage and maintenance

　　1. The users must undergo training and pass the examination before they can take up their posts to ensure the accuracy of the users.

　　To ensure safe wearing, the activity clip should be securely fastened. The safety hook should not be used in high temperatures above 120 ° C. Check before each use and stop using immediately if any abnormalities are found.

　　3. The safety belt should be hung high and used low to prevent swinging and collision. It is not allowed to tie the rope or directly hang it on the safety rope. It should be hung on the connecting ring and should not be used when the body is loaded.

　　four Single pillar anti collapse device for coal minesRegular cleaning should be carried out, and after use, it should be placed on a shelf and washed clean with soapy water. It should be stored in a warehouse with room temperature of 0 ℃ -30 ℃ and relative temperature below 80%. It should not come into contact with open flames, acid, sharp objects, or be exposed to sunlight.

　　5. After using the seat belt for one month, conduct a batch inspection according to the purchased quantity. Conduct a static load test on the fence belt with a tension of 225 kilograms for one minute, conduct an impact test on the suspended safety belt with a weight of 80 kilograms, and conduct a free fall test without breaking. Only when all components are undamaged or deformed can they continue to be used. Otherwise, they are not allowed to be used.
