Open caisson excavation method and vertical conveyor belt type earth cutting and dumping device
The open caisson excavation method comprises the steps that the device is placed on the top of an open caisson, an outer supporting wall is attached to the outer wall of the open caisson, an inner supporting wall is attached to the inner wall of the open caisson, a bottom translation assembly makes contact with the outer wall of the open caisson, and a motor is started to drive a main shaft to rotate; torque is transmitted to dumping rollers in the dumping belt through the power belt, the front dumping roller and the rear dumping roller of the dumping belt are in linkage through the dumping belt, the dumping belt transmits the torque to a main digging roller of the digging belt through the digging belt, the digging belt is driven to rotate through linkage and cooperation with an auxiliary digging roller, and an eccentric roller in the middle is driven to rotate through the digging belt. And meanwhile, the bottom of the motor is engaged with the translation assembly, so that the whole device can move around the outer surface of the open caisson, and the device has the beneficial effects that the device moves along the circumference of the open caisson during excavation, so that soil excavation is more uniform, and the excavation efficiency is improved.
本发明公开了一种沉井挖掘方法及垂直传送带式挖土排土装置，包括将装置放置在沉井顶部，外支撑壁与沉井外壁贴合，内支撑壁与沉井内壁贴合，底部平移组件与沉井外壁接触，启动电机带动主轴旋转，通过动力皮带将扭矩传递给排土皮带内部的排土辊，排土带前后两个排土辊通过排土皮带联动，排土带将扭矩通过挖土皮带传递给挖土带的挖土主辊，通过联动及与挖土副辊的配合带动挖土带旋转，且中部的偏心辊通过挖土带带动旋转，并通过联动改变挖土带的高度，同时电机底部与平移组件啮合，使整个装置能够绕沉井外表面移动，本发明的有益效果：在挖掘时沿沉井圆周运动，使得挖土更加均匀，提高了挖掘效率。
