Valveless reversing type anti-idle-hitting hydraulic breaking hammer
The invention discloses valveless reversing type anti-idle-hitting hydraulic breaking hammer, comprising an integrated outer cylinder, wherein a mounting cavity is formed in the outer cylinder, a piston is mounted in the mounting cavity, an oil conveying hole is formed in the outer cylinder, the oil conveying hole communicates with the mounting cavity and is used for reversing the moving direction of the piston, an inner sleeve and an outer sleeve are sequentially mounted at the position, close to the front end of the piston, in the mounting cavity of the outer cylinder, a guide sleeve is mounted in the outer sleeve, a drill rod is mounted in the guide sleeve, the mounting end of the drill rod is mounted in the outer sleeve, and buffering assemblies used for buffering impact force on the drill rod are arranged on the two sides of the mounting end of the drill rod. The outer cylinder is of an integrated structure, overall mounting is facilitated, the oil leakage phenomenon is avoided, and the piston can conduct automatic reversing without additionally mounting a reversing valve, so that the hydraulic breaking hammer is of a valveless reversing type structure, it can be guaranteed that the breaking hammer works smoothly, machining complexity is avoided, the requirement for the internal working environment is not high, and the use effect is improved.
本发明公开了一种无阀换向式防空打液压破碎锤，包括一体式外缸，外缸内开设有安装腔，安装腔内安装有活塞，外缸上开设有输油孔，输油孔与安装腔连通用于对活塞的移动方向进行换向，外缸的安装腔内靠近活塞前端位置处依次安装有内套和外套，外套内安装有导正套，导正套内安装有钎杆，钎杆的安装端安装在外套内，钎杆安装端的两侧位置处设置有用于对钎杆上的冲击力进行缓冲的缓冲组件，本发明的外缸为一体式结构，便于整体安装，不会出现漏油现象，并且无需加装换向阀，活塞能够进行自动换向，进而使该液压破碎锤为无阀换向式结构，既能保证破碎锤工作流畅，又避免加工复杂性，而且对内部工作环境要求不高，进而提高使用效果。
