AI Technical Summary
Existing milling machine guiding equipment has a large guiding error in the verticality of the trench and a poor stabilization effect, which can easily cause the trench wall to collapse, especially in soft strata.
A correction and guiding device including a baffle positioning system and a support plate is adopted. The baffle directly constrains the milling wheel cutting trajectory through the connecting plate and H-shaped steel plate and the vertical adjustment plate. The support plate is hinged to the bottom of the cutter head to counteract the lateral tilting force and ensure that the verticality error of the groove is within ±0.015mm. The support plate counteracts the lateral tilting force through a tensioning device.
The width error of the trough is effectively controlled within ±0.015mm, and the support plate maintains a contact pressure of 0.8MPa when encountering hard rock layers to counteract lateral deflection force, thereby improving guiding accuracy and stability.
