Description

Technical Field

[0001] This utility model belongs to the field of rock drilling technology, specifically a hydraulic breaker-type rock drilling device powered by a hydraulic system. Background Technology

[0002] Hydraulic breakers are widely used, especially in my country's rapidly developing construction industry. They are not only used for drilling, but also for the demolition of many buildings. The principle of existing hydraulic breakers is to inject hydraulic oil into the cylinder, which compresses the stored nitrogen and pushes the drilling head, thereby compressing the nitrogen chamber at the top. At this time, the control valve automatically reverses, so that the compressed energy in the top nitrogen chamber pushes the drilling head down and compresses the nitrogen in the storage chamber below. This process is repeated to achieve rapid raising and lowering of the drilling head, thereby achieving the purpose of drilling.

[0003] Existing hole-breaking heads include forms such as chisels and wedge modules. However, regardless of whether the existing hole-breaking device is in the form of a chisel or wedge module, the connecting arms at the front end are installed at a fixed angle. This allows for the application of propulsive force along the axial direction of the connecting arms, i.e., the chisel or wedge module, after obtaining power from the gantry crane, excavator, or loader pump station. However, in actual operation, multi-sided inclined working surfaces are often encountered. In such cases, it is difficult for the axis of the chisel or wedge module to be perpendicular to the working surface. Frequent angle adjustments are required by using the connecting arms or even moving the excavator. However, the connecting arms are large, and the adjustment is energy-intensive and inefficient. If the chisel or wedge module is not perpendicular to the working surface, the axial hammering force cannot be applied to the working surface effectively, and it is difficult to insert it into the borehole. This not only reduces work efficiency and energy utilization but also poses certain safety hazards. Therefore, it is necessary to develop a new type of hydraulic breaker-type hole-breaking device to address the shortcomings of the existing technology. Utility Model Content

When it is necessary to adjust the angle of the breaking head 5 to be perpendicular to the working surface, the hydraulic cylinder is activated by the control system integrated into the excavator. With the cooperation of the oil supply pipe 7, connecting pipe 6, and connecting pipe 8, the hydraulic oil in the connecting hole 225 and the sealing cavity 224 is extracted. Then, under negative pressure, the locking tooth plate 261 is disengaged from the locking gear 24. At this time, the mechanical arm controls the movement and, with the cooperation of the working surface, it abuts against the breaking head 5 until the breaking head 5 is perpendicular to the working surface. Then, the pneumatic hydraulic cylinder is activated again to inject hydraulic oil in reverse into the connecting hole 225 and the sealing cavity 224, which keeps the first steering locking assembly 2 and the second steering locking assembly 3 locked, so that the angle of the breaking head 5 is always perpendicular to the working surface. Then, the operation of the hydraulic cylinder group 4 is controlled by the control system inside the excavator, so that the breaking head 5 can continuously impact and hammer the stones on the working surface.
