Description

Field of the Invention

[0001] The present invention belongs to the field of machinery, and particularly relates to a method of equipment for converting rotary motion into reciprocating impact motion and equipment for converting rotary motion into reciprocating impact motion for implementing the method, which are suitable for the field of digging or the field of engineering machinery.

Background of the Invention

[0002] Since the driving shaft of an existing drilling and milling cutting type heading machine is arranged along the longitudinal direction of a rocker arm, in telescoping processes, a drilling and milling cutting head is liable to generate break-off damage to such transmission components as a spline shaft, a spline sleeve and the like, after being damaged, a motor or a speed reducer can only be maintained after multiple positions of the rocker arm are detached, thus resulting in large maintenance difficulty, labor consumption, time consumption and assembly difficulty, and in the maintenance and detachment processes, undamaged components are liable to be damaged, the precision of the assembly structure of the equipment is reduced, the application failure is increased and the service life of the entire machine is shortened.

[0003] The working manner of a rocker arm excavator is that the rocker arm is driven by hydraulic power to telescope and is driven by the hydraulic power to excavate materials, and a working manner of converting rotary motion into reciprocating impact motion is not used, so that the rocker arm and/or an excavating component thereof acts slowly to cause low working efficiency.

[0004] The working principles and manners of a reciprocating impact type heading machine and a drilling and milling type heading machine are different, if the structure that the driving shaft of the drilling and milling type heading machine is arranged along the longitudinal direction of the rocker arm is still used, an impact power box is liable to generate break-off damage to such transmission components as the spline shaft, the spline sleeve and the like during telescoping and/or rotary impact, moreover the manufacturing difficulty and/or mounting complexity is increased and the failure rate of the equipment is increased.

[0005] In order to solve the above-mentioned problems, the present invention provides a method of equipment for converting rotary motion into reciprocating impact motion and equipment for converting rotary motion into reciprocating impact motion for implementing the method.
