Hydraulic breaking hammer and engineering machinery
The invention belongs to the field of engineering machinery, and discloses a hydraulic breaking hammer and engineering machinery. The piston rod is arranged in the middle cylinder body; the continuous reversing loop is arranged among the breaking hammer oil inlet, the breaking hammer oil return port and the middle cylinder body and is used for controlling the piston rod to reciprocate in an initial stroke; and the frequency conversion triggering oil way is arranged between the continuous reversing loop and the middle cylinder body and is used for triggering the reversing time of a main control hydraulic reversing valve in the continuous reversing loop to be changed, so that the piston rod can be adjusted to do reciprocating motion in a non-initial stroke. According to the hydraulic breaking hammer, the reciprocating stroke of the piston rod can be adjusted in a large range, the striking frequency or striking force can be automatically adjusted, and therefore the breaking work amount can be increased, the working efficiency can be improved, the hydraulic breaking hammer is suitable for different breaking working conditions, re-matching type selection of the hydraulic breaking hammer is not needed, and resource waste is avoided.
本发明属于工程机械领域，公开了一种液压破碎锤和工程机械，其中的液压破碎锤包括：中缸体；活塞杆，设置在中缸体内；连续换向回路，设置在破碎锤进油口、破碎锤回油口和中缸体之间且用于控制活塞杆以初设行程往复运动；和变频触发油路，设置在连续换向回路和中缸体之间且用于触发连续换向回路中的主控液动换向阀的换向时机产生变化，以能够将活塞杆调节为以非初设行程往复运动。本发明的液压破碎锤能够大范围调节活塞杆的往复运动行程，自动调节打击频率或打击力，从而能够提升破碎作业量，提高工作效率，适于不同的破碎工况使用，无须对液压破碎锤重新匹配选型，避免造成资源浪费。
