AI Technical Summary
Existing mining anchor cable tensioning equipment is prone to slippage and displacement due to external forces during use, resulting in poor stability.
Auxiliary components, including L-shaped supports and hydraulic rod assemblies, are installed on the front and rear sides of the anchor tensioning machine's placement trolley. The threaded ground nails are driven into the mine floor by the hydraulic rods and rotary drive unit. The stability of the machine is ensured by the auxiliary ground insertion assembly and the limiting assembly. The auxiliary ground insertion assembly is detachable for easy replacement.
This improves the stability of the anchor cable tensioning equipment during use, and allows for the replacement of components when they wear out, ensuring the long-term reliability of the equipment.
