Hydraulic-mechanical combined rock-breaking milling wheel and double-wheel slot milling machine

Abstract

The invention relates to a hydraulic-mechanical combined rock-breaking milling wheel and a double-wheel slot milling machine. The milling wheel comprises a milling wheel body, multiple milling teeth,multiple cutting teeth, a milling wheel spindle and a high-pressure water jet device, wherein the multiple milling teeth are fixed to the circumference of the milling wheel body; the multiple cuttingteeth are arranged in a ring at the inner side of the milling wheel body; the milling wheel spindle drives the milling wheel body to rotate through a milling wheel driving mechanism; the high-pressurewater jet device comprises a nozzle controller, multiple edge-trimming nozzles, multiple rock-breaking nozzles, multiple blind area milling nozzles and multiple fixing components; the nozzle controller is fixed into a through hole of the milling wheel spindle to rotate synchronously with the milling wheel spindle; and the edge-trimming nozzles, the rock-breaking nozzles and the blind area millingnozzles are fixed to the milling wheel body through the fixing components respectively. Through the double-wheel slot milling machine, the rock-breaking efficiency and the rock-breaking effect are both improved to a certain extent compared with a traditional mechanical rock-breaking mode, tool wear is small, a milling blind area has a good milling effect, and improvement to construction efficiency and reduction of construction cost are benefited.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to a hydraulic machinery combined with a rock-breaking milling wheel and a double-wheel groove milling machine. Background technique [0002] With the development of engineering technology, underground diaphragm wall is a new technology developed rapidly and widely used in foundation construction engineering and underground concealment technology. The underground diaphragm wall is poured as a whole, which has the advantages of high structural rigidity, good integrity, good anti-seepage performance, high durability, relatively little impact on the surrounding foundation structure and buildings, and is suitable for a wide range of strata. It is widely used in fields such as water conservancy reservoirs, port construction, housing construction and municipal engineering. The double-wheel groove milling machine is a special equipment used for the construction of undergro...
