Earthwork excavation equipment for municipal road construction
The invention relates to the technical field of earthwork excavating equipment, in particular to earthwork excavating equipment for municipal road construction, which comprises a machine body, a movable arm, a bucket rod and a bucket are mounted on the machine body and are driven by a hydraulic cylinder to perform excavating action, and the hydraulic cylinder comprises a piston I and a piston rod which are movably sleeved in a cylinder barrel; a cylinder cover I and a cylinder cover II are fixedly installed at the two ends of the cylinder barrel correspondingly, an arc-shaped groove I is formed in the cylinder cover I, a sealing block connected with the outer side of the piston rod in a sealed mode is arranged on the outer edge of the arc-shaped groove I, and an arc-shaped groove II opposite to the arc-shaped groove I in direction is formed in the piston I; a sealing block in sealing connection with the inner wall of the cylinder barrel is arranged on the outer edge of the arc-shaped groove II. Part of friction resistance of the contact portion of the cylinder cover I and the outer side of the piston rod is counteracted through the pressure of oil entering the arc-shaped groove I, and part of friction resistance of the contact portion of the piston I and the inner wall of the cylinder barrel is counteracted through the pressure of oil entering the arc-shaped groove II.
本申请涉及土方挖掘设备技术领域，具体公开了一种市政道路施工用土方挖掘设备，包括机体，机体上安装有动臂、斗杆和铲斗，动臂、斗杆和铲斗均通过液压缸驱动进行挖掘动作，液压缸包括缸筒内活动套装的活塞Ⅰ和活塞杆，所述缸筒的两端分别固定安装有缸盖Ⅰ和缸盖Ⅱ，所述缸盖Ⅰ上开设有弧形槽Ⅰ，所述弧形槽Ⅰ的外边缘设置有与活塞杆外侧密封连接的密封块，所述活塞Ⅰ上开设有与弧形槽Ⅰ方向相反的弧形槽Ⅱ，弧形槽Ⅱ的外边缘设置有与缸筒内壁密封连接的密封块。由进入弧形槽Ⅰ内的油液压力，抵消缸盖Ⅰ与活塞杆外侧接触部位的部分摩擦阻力，由进入弧形槽Ⅱ内的油液压力，抵消活塞Ⅰ与缸筒内壁接触部位的部分摩擦阻力。
