Design and research of underwater hydraulic driven diamond chain saw cutting machine

The hydraulic driven chain saw is a cutting tool for underwater operation. The hydraulic driven chain saw was designed, the hydraulic adjusting device was designed, the hydraulic chain saw experimental platform was designed, the sawing efficiency and power consumption experiments were carried out, and the diamond saw chain wear experiment was carried out. The experimental results show that:When cutting C25 standard reinforced concrete floor plate, the tension of tight edge of diamond saw chain is large; the dynamic load of diamond saw chain has the greatest influence on the tension of diamond saw chain, and the dynamic load is proportional to the rotation speed of chain wheel, the pitch of diamond saw chain, the weight per meter of diamond saw chain and the length of tight edge, among which the rotation speed of chain wheel has an effect on it The noise is the largest; the power consumption of cutting concrete is 2.85kw, the efficiency of sawing concrete is 0.93m2/h, and the sawing area of diamond saw chain per meter is 16.7m2/m.
