Tooth distribution system for milling wheel of double-wheel slot milling machine

Abstract

The invention relates to a tooth distribution system for a milling wheel of a double-wheel slot milling machine. The tooth distribution system comprises a milling wheel main body. Tooth seat plates are positioned and arranged on a left hub and a right hub of the milling wheel main body. Multiple cut teeth are welded and fixed on each tooth seat plate. The cut teeth are symmetrically arranged on the left hub and the right hub according to the tooth distribution rule. The left hub is expanded along the outer circumference of the hub, the expansion plane is divided into multiple equal parts alongmultiple axial bisectrices in the axial direction and meanwhile divided into multiple equal parts along the circumference bisectrix in the circumferential direction. The cut teeth on the left hub aredivided into the middle cut teeth, the outer cut teeth, the inner cut teeth and the groove repairing cut teeth, and meanwhile all the cut teeth are reasonably distributed on the corresponding hubs according to the optimal stress space angle. The tooth distribution system has the beneficial effects that the rock stratum application range is wide, the rock breaking stress is uniform, the wear of milling teeth is small, and the milling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of a milling wheel tooth arrangement system, in particular to a milling wheel tooth arrangement system for a double-wheel slot milling machine used for underground continuous wall construction. Background technique [0002] Diaphragm wall is a new technology that has been rapidly developed and widely used in foundation construction projects and underground concealed projects for more than half a century. The underground diaphragm wall first originated in Europe, and the underground diaphragm wall construction method using special equipment in foreign countries is a low-noise and low-vibration construction method. Because the wall is integrally cast, the underground diaphragm wall has the characteristics of high structural rigidity, good integrity, high anti-seepage performance and long durability, little impact on the surrounding foundation, less impact on the environment of adjacent structures, and a wide r...

Problems solved by technology

Since the peripheral milling teeth of the milling wheel system directly interact with the rock and soil during the milling operation of the equipment, the arrangement of the milling teeth on the milling wheel is crucial to the rock crushing efficiency and milling speed, including the movement trajectory of the milling teeth, the cutting rock area, the cutting The determination of tooth layout parameters such as angle, cutting point spacing, and side wall residual milling, but the current research on this aspect is still blank
