AI Technical Summary

Technical Problem

In existing underwater rock processing methods, when high-frequency rock crushing is performed solely by the deadweight of the rock-splitting and crushing device, rebound and bouncing will occur when encountering hard rock, resulting in poor crushing effect, safety risks, and high costs.

Method used

An underwater rock cracking device was designed, which combines a high-pressure gas storage hydraulic cylinder and a pulley block. The flexible pressure of the high-pressure gas storage hydraulic cylinder is used to tighten the pressure rod cable, so that the cutter head always sticks to the rock for crushing. A high-frequency vibration generator is used to achieve efficient crushing. Combined with the coordination of the pulley block and the lifting cable, the stable operation of the device is ensured.

Benefits of technology

It improves the efficiency and safety of underwater rock crushing, reduces construction costs, enhances the crushing effect, and avoids the problem of rebound and bouncing.

Abstract

The present invention provides an underwater rock-splitting device and construction process, including a rock-splitting and crushing device; a stand is arranged on a platform; a two-way undulating winch is arranged on one side of the stand, a cross frame is fixedly installed on the stand, and a sliding bar that can move up and down is also provided on one side of the cross frame, and the rock-splitting and crushing device is arranged at the lower end of the sliding bar; a first pulley group and a second pulley group are respectively provided on the upper and lower sides of the cross frame; a push rod of a high-pressure gas storage hydraulic cylinder is connected to one of the pulleys of the first pulley group, and the flexible pressure of the high-pressure gas storage hydraulic cylinder tightens the pressure bar cable, so that the cutter head always sticks to the rock to perform crushing work, which plays the role of pressing the sliding bar downward. The present invention adds a pressurizing device to the rock-splitting and crushing device, and cleverly uses the flexible pressure of the high-pressure gas storage hydraulic cylinder to tighten the pressure bar cable, so that the cutter head of the rock-splitting and crushing device always sticks to the rock to perform high-frequency crushing work, which has a good crushing effect and greatly increases work efficiency.
