Description

Technical Field

[0001] The utility model relates to the technical field of disassembly tools, in particular to a drilling rig oil pressure buffer disassembly tool. Background Art

[0002] The function of hydraulic buffer is to reduce vibration and noise in the operation of automated machinery, convert the kinetic energy generated by the moving object into heat energy and release it into the atmosphere, and effectively stop the object in balance during the action. When the axis of the hydraulic buffer is impacted by external force, it will drive the piston to squeeze the hydraulic oil in the inner tube. After the hydraulic oil is compressed, it will be discharged one by one from the oil discharge holes of the inner tube. At the same time, the hydraulic oil discharged from the inner tube will also flow back to the inner tube through the oil return hole of the inner tube; when the external force disappears, the spring will rebound the piston to the starting point to wait for the next action.

[0003] For example, CN219617652U discloses a hydraulic buffer disassembly tool, which has a disassembly function, is easy to operate, saves time and effort, and has the characteristics of simple structure, convenient processing and easy assembly, and is highly practical. However, in actual use, only specific hydraulic buffers can be disassembled, and there are certain limitations when disassembling hydraulic buffers of different sizes and models. In addition, the driving rod needs to be rotated with the help of a wrench or an electric tool, which is inconvenient to operate without suitable tools.
