Principle Of Mining Anchor Cable Tensioning Machine

The working principle of the mining anchor cable tensioning machine is mainly to achieve the tensioning and installation of the anchor cable through the hydraulic system. When the hydraulic pump starts working, the oil enters the working tensioning jack through the high and low pressure oil suction check valves. As the pressure increases, when it reaches 1.5MPa, the low pressure relief valve opens and the low pressure oil flows back to the oil tank. Continue to increase the pressure, the high pressure plunger continues to work, the pressure gradually increases, and the tensioning jack is pushed to work to achieve the tensioning of the anchor cable. When the pressure exceeds 63MPa, the high pressure valve opens, and the high pressure oil flows back to the oil tank to maintain the pressure at 63MPa.

The mining anchor cable tensioning machine consists of multiple parts, including a two-speed reversing oil pump, a high pressure oil pipe assembly and an anchor cable puller. These components work together to ensure that the equipment is small, light and easy to operate. Its rated pressure is 200KN, the piston stroke is 70MM, the operating resistance does not exceed 50KN, and it is suitable for environmental conditions from -20℃ to 45℃.

Mine anchor cable tensioning machine is widely used in various construction sites such as coal, national defense, tunnels and transportation, with the characteristics of simple operation, convenient carrying and safety. It plays an important role in the anchor cable support of coal mine tunnels to ensure the tensioning and installation quality of the anchor cable.
