| 摘要 |
The present invention discloses a hydraulic resonant breaking hammer, comprising a hydraulic driving system, a vibration exciter (2), a control system, a linkage mechanism and a breaking hammer head (3), wherein the hydraulic driving system includes a hydraulic motor (1), an electric-control hydraulic distributing valve (12), a hydraulic pump (13) and an engine (14); the vibration exciter (2) includes a box (4) and at least one group of eccentric wheels; the control system includes a sensor (16), a microcomputer controller (17) and the electric-control hydraulic distributing valve (12); the linkage mechanism includes a machine frame (7), a guide rail (9) and a damper spring (8), the machine frame (7) is installed on a fore arm (10) of an excavator, the guide rail (9) is arranged on the machine frame (7), the box (4) of the vibration exciter (2) is arranged on the guide rail (9) and forms an up-and-down sliding fit with the guide rail (9), the damper spring (8) is connected between the upper part of the box (4) and the machine frame (7), and the breaking hammer head (3) is arranged at the lower part of the box. The present invention solves the problems of the existing engineering breaking devices, such as low efficiency, high noise, serious damages to the driving excavator caused by the reaction of an impact force and incapability of breaking large rocks.
