Tamping mechanism as well as frame type tamping device and railway ballast tamping equipment comprising tamping mechanism
The tamping mechanism comprises a connecting frame, and tamping units are connected to the two ends of the connecting frame correspondingly; the tamping unit comprises a box body, and a left pickaxe arm and a right pickaxe arm which are hinged and supported on the box body; the box body is inverted-Y-shaped, the left and right ends of the box body are respectively hinged to the middle parts of the left and right pickaxe arm components, the upper part supports the eccentric crankshaft component, and one side surface of the box body is provided with a mounting surface connected with the connecting frame; the eccentric crankshaft part comprises eccentric crankshafts which form hinge pairs with the inner ends of the cylinder bodies of the left clamping oil cylinder and the right clamping oil cylinder respectively; the left and right clamping oil cylinders comprise left and right piston rods of which the extending ends are respectively hinged with the upper parts of the left and right pickaxe arms; the lower portion of each pickaxe arm is provided with a pair of pickaxe feet stretching across one steel rail. The left tamping unit and the right tamping unit are connected into a whole through the connecting frame, downward inserting and lifting actions of the left tamping unit and the right tamping unit are achieved through the single lifting oil cylinder, a power source is concentrated, the speed is high, synchronism is good, and the frame is more stable, long in service life, low in failure rate, simple in structure and convenient to maintain.
本申请公开了一种捣固机构，包括连接架，两端分别连接有捣固单元；捣固单元，含有箱体及铰支于箱体上的左、右镐臂；箱体，呈倒Y型，其左、右两端分别铰支左、右镐臂部件的中部，上方支撑偏心曲轴部件，其一侧面设有与连接架连接的安装面；偏心曲轴部件，含有分别与左、右夹持油缸的缸体内端构成铰接副的偏心曲轴；左、右夹持油缸，含有外伸端分别与左、右镐臂上部铰接的左、右活塞杆；左、右镐臂，每个镐臂的下部分别装有一对横跨一股钢轨的镐脚。本申请左右捣固单元通过连接架连接成一体，且采用单个提升油缸实现左右捣固单元的下插与提升动作，动力源集中，速度快，同步性好，使框架更加稳定寿命长，故障率低，结构简易，维护方便。
