Abstract

The invention discloses a small-size hydraulic device for prediction on the basis of tunnel face front rock. The device comprises a bottom plate, wherein the top and the bottom of the bottom plate are respectively and fixedly connected with a driving hydraulic motor; an output shaft of the driving hydraulic motor is fixedly connected with a first speed change gear; the right side of the first speed change gear is engaged with a second speed change gear; the right side of the second speed change gear is engaged with a third speed change gear; one side of the third speed change gear is fixedly connected with a transmission gear. The small-size hydraulic device relates to the technical field of tunnel face front rock. The small-size hydraulic device for prediction on the basis of tunnel face front rock reaches the goal that the inner and outer cutter heads rotate in opposite directions; the structure is reasonable; the practicability is high; safety and reliability are realized; the structural design of the inner cutter head and the outer cutter head is used, the goal of meeting the crushing requirement during the efficient propulsion is achieved; the high-frequency vibrator achieves the tamping effect during the propulsion through high-frequency extraction and vibration; the self stability is improved; the self stabilization time is prolonged; good construction environment is created for the subsequent construction.

Description

technical field [0001] The invention relates to the technical field of rock prediction in front of a tunnel face, in particular to a small hydraulic device for rock prediction in front of a tunnel face. Background technique [0002] The surrounding rock is also called the main rock and the ore-hosting rock. The rocks around the ore body and the rock mass are called the surrounding rock. However, the former is the surrounding rock of the ore body, and the latter is the surrounding rock of the rock mass. The ore body and the surrounding rock There are roughly two situations for the relationship between the ore body and the surrounding rock: there are significant differences in the fabric and the content of useful components between the ore body and the surrounding rock, and the contact boundary is clear, such as the relationship between the vein-shaped filling ore body and the surrounding rock, and the ore body and the surrounding rock. The boundary between the ore body and th...
