Description

Technical Field

[0001] This invention relates to the field of geological drilling technology, and in particular to a rock drilling device. Background Technology

[0002] When conducting geological exploration for engineering projects, rock drilling equipment is often used to drill downwards from the surface, forming cylindrical boreholes in the strata to identify and classify the strata. During the drilling process, construction personnel are usually stationed at the mining site to ensure the smooth progress of the construction.

[0003] As described in existing application number CN202310483034.X, a rock drilling device for engineering geological exploration is provided, relating to the field of geological drilling technology. The device includes a drilling equipment base plate, on which a drilling component tilting seat is fixedly installed on the upper surface. A drilling component is rotatably mounted on the tilting seat. A frame support plate is integrally connected to the front end of the base plate. Vertical limiting components are fixedly installed at both ends of the inner surface of the frame support plate near the drilling component. This invention rotates the drilling component onto the tilting seat at the upper end of the base plate and uses a tilting winch installed on one side to pull one end of the drilling component by winding three tilting steel cables, causing it to tilt. The three tilting steel cables are tightened at multiple points, making the drilling component more stable when upright. After the drilling component tilts to its correct position, its bottom end is locked onto the vertical limiting components, further stabilizing the drilling component.

When the equipment is running continuously, the debris can easily fly onto the workers, which can cause unnecessary trouble and safety hazards.
