The invention provides a hoisting angle fine adjustment device for a shield tunneling machine front cutter dragging oil cylinder, and relates to the technical field of shield tunneling machines. The hoisting angle fine adjustment device comprises a hoisting adjusting plate, a fixing pin shaft is slidably arranged at the bottom end of the hoisting adjusting plate in a penetrating mode, and a limiting block is movably connected to the end, close to the fixing pin shaft, of the hoisting adjusting plate. According to the hoisting angle fine adjustment device for the shield tunneling machine frontcutter dragging oil cylinder, the position of the limiting block is adjusted through an adjusting bolt, the hoisting angle of the hoisting adjusting plate is changed, and the effect of stably and effectively adjusting the angle of the oil cylinder in the hoisting process is achieved; the fixing pin shaft and an oil cylinder fixing sleeve are additionally arranged, the oil cylinder fixing sleeve isprovided with an upper clamping ring and a lower clamping ring, and the oil cylinder is fixed through locking of the upper clamping ring and the lower clamping ring; and an anti-loose gasket and a locking nut are additionally arranged on the fixing pin shaft, so that the oil cylinder and the whole device have relatively stable stability, and the situation that angle fine adjustment cannot be carried out due to separation of the oil cylinder and the device is avoided. The structure is simple, adjustment is convenient, the problems that the inclination angle is large, and the oil cylinder is difficult to fix are solved, and the installation efficiency of the shield tunneling machine front cutter dragging oil cylinder is greatly improved.
本发明提供一种用于盾构机正面刀拖拉油缸吊装角度微调装置,涉及盾构机技术领域,包括吊装调节板,所述吊装调节板的底端滑动贯穿有固定销轴,所述吊装调节板靠近固定销轴的一端活动连接有限位块。本发明,调节螺栓调节限位块位置,改变吊装调节板的吊装角度,达到稳定有效的在吊起过程中调节油缸角度的作用,装置通过加装固定销轴和油缸固定套,油缸固定套具有上下卡圈通过锁紧对油缸进行固定,固定销轴上加装防松垫圈和锁紧螺母,使油缸与装置整体具有相对稳固的稳定性,避免油缸与装置脱离无法进行角度微调,本发明结构简单,调节方便,解决了倾斜角度大,难固定油缸的问题,大大提高了盾构机正面刀拖拉油缸的安装效率。
