介绍一种拆卸、安装泵送装置砼活塞的专用工具。该工具包括拆卸和安装两部分,并且集成于一体。拆卸工具主要包括安装盘及抓钩,抓钩的端部具有与所需要拆装的砼活塞尾部相钩合的结构,安装盘端后部有与驱动砼活塞的液压活塞杆端部固定的结构;安装工具主要由一根丝杆和螺母组成。在使用该专用工具拆卸和安装砼活塞时,能够确保砼活塞受力均匀,避免密封体的损坏,可有效提高砼活塞的更换效率和更换质量。
Describes a special tool for disassembly and installation of concrete pistons for pumping equipment. The tool includes disassembly and installation of two parts, and integrated. The disassembly tool mainly comprises a mounting plate and a grasping hook. The end of the grasping hook has a structure which is matched with the tail of the concrete piston to be disassembled. The rear end of the mounting disk has a structure which is fixed with the end of the hydraulic piston rod which drives the concrete piston ; Installation tools mainly by a screw and nut composition. When using the special tool to disassemble and install the concrete piston, it can ensure the uniform stress of the concrete piston and avoid the damage of the sealing body, which can effectively improve the replacement efficiency and replacement quality of the concrete piston.
