▎ 摘 要
NOVELTY - The device has a bottom plate (1), an adjusting mechanism (2) and a height clamping mechanism (3). The adjusting mechanism is fixedly installed on the top surface of the bottom plate. Two curved rods are movably connected to the inner walls of the two sliding groove plates. A fixing plate is fixedly installed on the top of the curved rod on the same side. A connecting rod is fixedly installed in the middle of the bottom end of the fixing plate. A connecting plate (5) is fixedly installed at the bottom end of the connecting rod. A protective frame is fixedly installed in the middle of the top surface of the bottom plate. A partition plate is fixedly installed in the middle of the inner side wall of the protective frame. Electric telescopic rods are fixedly installed on the left and right ends of the partition plate. One end of the electric telescopic rod away from the partition plate is fixedly installed on the side surface of the connecting plate. USE - Mining hydraulic support repairing device for use in coal mining process. ADVANTAGE - The device is capable of adjusting the distance of the needed fixing support, ensures the stability of the support, and flexibly adjusts the clamping direction of the support, increasing the convenience of operation. The hydraulic support repairing material produced by the method has low manufacturing cost and corrosion resistance, excellent corrosion resistance and good wear-resistant performance and damping effect, through the upper lead furnace graphene adding process, uniformly distributed graphene structure in the upper guide rod tissue, and subsequent drawing and annealing process combination and wire peeling process. The corrosion and surfacing hardness of the hydraulic support repair material processed by the process are better than that of the existing conventional high manganese aluminum bronze material, which effectively improves the service life and safety performance of hydraulic support for mining. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing mining hydraulic support repairing material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a mining hydraulic support repairing device. 1Bottom plate 2Adjusting mechanism 3Height clamping mechanism 4Springs 5Connecting plate
