Hydraulic breaking hammer and working machine
The invention relates to the technical field of engineering machinery, and discloses a hydraulic breaking hammer and an operation machine. The cylinder body is provided with a working cavity and an energy storage cavity, and the working cavity sequentially forms a first cavity, a second cavity and a third cavity in the direction away from the energy storage cavity; a first reversing valve; when the piston moves to the rightmost side and is about to move towards the drill rod, the third cavity is communicated with the first low-pressure oil way through the oil way control assembly, and the third cavity is communicated with the second low-pressure oil way through the oil way control assembly. When high-pressure oil in the first cavity and compressed gas in the energy storage cavity push the piston to move leftwards, hydraulic oil in the third cavity can be discharged through the first low-pressure oil way, the hydraulic oil discharging mode can greatly reduce resistance generated when the piston moves leftwards, and the service life of the hydraulic breaking hammer is prolonged under the conditions that the striking frequency of the hydraulic breaking hammer is not affected and the equipment failure rate is not increased. And the hitting power of the hydraulic breaking hammer is obviously improved.
本发明涉及工程机械技术领域，公开了液压破碎锤及作业机械，液压破碎锤，包括：活塞；缸体，具有工作腔以及蓄能腔，工作腔沿着远离蓄能腔的方向依次形成第一腔、第二腔和第三腔；第一换向阀；油路控制组件，第三腔通过油路控制组件与高压油路和第一低压油路择一连通，本发明中当活塞移动到最右侧并即将朝向钎杆移动时，此时油路控制组件将第三腔与第一低压油路连通，第一腔的高压油以及蓄能腔中的压缩气体推动活塞左移时，第三腔中的液压油即可通过第一低压油路排出，此种液压油排出方式可大大减小活塞左移时的阻力，在不影响液压破碎锤的打击频率以及不提升设备故障率的情况下，显著提升了液压破碎锤的打击力。
