Description

Technical Field

[0001] The utility model relates to the technical field of breaking hammers, in particular to a hydraulic breaking hammer with a detachable buffer component. Background Art

[0002] Hydraulic breaker is referred to as "breaker" or "breaker". The power source of hydraulic breaker is the pressure provided by excavator, loader or pump station. It can break stones and rocks more effectively in engineering construction and improve work efficiency. The principle of selecting hydraulic breaker is to choose the most suitable hydraulic breaker according to the excavator model and working environment.

[0003] Chinese patent announcement No. CN216195026U discloses a hydraulic breaker with a buffer structure, which belongs to the technical field of hydraulic breaker hammers, including a hydraulic hammer unit and a fixedly connected guard plate unit installed on the hydraulic hammer unit. A plate body is fixedly arranged on the hydraulic cylinder, and connecting blocks with through holes are fixedly welded at the four corners of the plate body, and a positioning guide column with a return spring on the upper end is fixedly welded to the side of the reinforced side plate through welding blocks welded at both ends, and the upper end of the return spring is fixedly welded on the welding block, and the positioning guide column is movably inserted in the through hole. When the hydraulic cylinder drives the hammer head to hammer and generate vibration, the hydraulic cylinder moves up, and the return spring buffers and absorbs the impact force of the upward movement, thereby reducing the impact between the excavator arm and the connecting end of the arm, and playing a good buffering and protective effect. However, the protective components of the device are mostly welded, and it is difficult to observe the operation of the protective components in time, and it is difficult to disassemble and repair the protective components if there are problems in the later stage, which affects the normal progress of the project.

[0004] In view of the above, a hydraulic breaker with a detachable buffer component is proposed. The device realizes rapid disassembly and assembly of the protective component and facilitates observation of the operation of the protective component through the setting of the protective component, the positioning component and the limit component, thereby ensuring the normal progress of the project.
