小型搅拌车搅拌筒停转是怎么回事?

作者:http://www.zkzsljbc.com 时间:2020-11-03

(一)小型搅拌车搅拌筒停转的处理
(1) Treatment of small mixer drum stop running
检查搅拌筒托轮以及马达,看是否是有土石杂物卡住,如果有,将杂物清理干净即可。如果不是由于杂物卡住无法转动,立刻呼叫救援车。在有条件排放混凝土的情况下,可以将马达上的高压软管的管接头卸下,旋转搅拌筒,让搅拌筒检修孔向下,将混凝土从检修孔排出。救援车到场后,将故障车马达上的高压软管卸下,接上救援用高压软管,另一端接在救援车油泵上,同时把应急用的回油管连接在故障车马达泄油口位置,另一端连接在救援车油泵回油口,利用救援车对故障车的小型小型搅拌车进行控制旋转,直混凝土排出。如有条件的情况下,可以直接更换出现故障的马达,更换马达后接好各个油管,搅拌筒即可正常旋转。
Check the supporting wheel and motor of the mixing drum to see if there is any debris stuck. If so, clean up the debris. If it is not due to debris stuck, call the rescue vehicle immediately. Under the condition that concrete can be discharged, the pipe joint of the high-pressure hose on the motor can be removed, and the mixing drum can be rotated to let the access hole of the mixing cylinder go down to discharge the concrete from the manhole. After the rescue vehicle arrives at the scene, remove the high-pressure hose from the motor of the fault vehicle, connect the high-pressure hose for rescue, and connect the other end to the oil pump of the rescue vehicle. At the same time, connect the emergency oil return pipe to the oil drain port of the motor of the failure vehicle, and connect the other end to the oil return port of the oil pump of the rescue vehicle. The small-scale mixer truck of the failure vehicle is controlled to rotate until the concrete is discharged. If conditions permit, the motor that fails can be replaced directly. After the motor is replaced, each oil pipe is connected, and the mixing drum can rotate normally.
(二)小型搅拌车搅拌筒的构造和工作原理
(2) Structure and working principle of mixing drum of small mixer truck
小型搅拌车搅拌筒绝大部分都采用梨型结构,搅拌筒通过支承装置斜卧在机架上,可以绕其轴线转动,搅拌筒的后上方只有一个筒口分别通过进出料装置进行装料或卸料。整个搅拌筒的壳体是一个变截面而不对称的双锥体,外形似梨型,底段锥体较短,端面封闭并焊接着法兰,通过连接法兰用螺栓与减速器联结。
小型搅拌车
Most of the mixing cylinders of small-sized mixer truck are pear shaped. The mixing drum is inclined on the frame through the supporting device and can rotate around its axis. There is only one opening on the upper rear of the mixing drum, which is loaded or unloaded through the feeding and discharging device respectively. The shell of the mixing drum is a variable cross-section and unsymmetrical double cone, the shape is pear shaped, the bottom cone is short, the end face is closed and welded with flange, and the reducer is connected with bolts through the connecting flange.
上段锥体的过度部分有一条环行滚道,它焊接在垂直于搅拌筒轴线的平面圆周上,整个搅拌筒通过连接法兰和环形滚道倾斜卧置在固定与机架上的减速器壳体和一对支承滚轮所组成的三点支承结构上,由减速器带动平稳的绕其轴线转动。在搅拌筒滚道圆周上部,通常设有钢带护绕,以限制搅拌筒在小型搅拌车颠波行驶时向上跳动。
The transition part of the upper cone has a circular raceway, which is welded on the plane circumference perpendicular to the axis of the mixing drum. The whole mixing drum is inclined to lie on the three-point support structure composed of the reducer shell fixed on the frame and a pair of supporting rollers through the connecting flange and the annular raceway, and the reducer drives the smooth rotation around its axis. A steel band is usually set on the upper part of the circumference of the mixing drum raceway to limit the upward jump of the mixing drum when the small mixer truck is running in a bumpy wave.
小型搅拌车搅拌筒的内部结构,它与双锥形和梨形搅拌机的内部结构都不同,这是为了适应在单一筒口不倾翻反转卸料和进料搅拌的工艺要求而设计的。搅拌筒从筒口到筒底沿内壁对称焊接着两条连续的带状螺旋叶片,当搅拌筒转动时,两条叶片既被带动作围绕搅拌筒轴线的螺旋运动,这是搅拌筒对混凝土进行搅拌或卸料的根本装置。另外,为了加强搅拌效果,在搅拌筒的中下部两条螺旋叶片间加装有辅助搅拌叶片。
The internal structure of small mixer drum is different from that of double cone mixer and pear shaped mixer. It is designed to meet the process requirements of unloading and feeding mixing without overturning at a single drum mouth. Two continuous ribbon spiral blades are symmetrically welded along the inner wall from the barrel mouth to the bottom of the mixing drum. When the mixing drum rotates, the two blades are driven to move around the axis of the mixing drum, which is the fundamental device for mixing or discharging concrete. In addition, in order to enhance the mixing effect, an auxiliary mixing blade is installed between the two spiral blades in the middle and lower part of the mixing cylinder.
