The invention provides a convenient-to-maintain subway maintenance false trolley with a protection device which comprises a movable frame, movable trundles, internal threaded holes, adjusting screw rods, adjusting hand wheels, supporting foot seats, a maintenance platform, a maintenance box, an impurity filtering net and a control panel, and is characterized in that the movable trundles are in bolted connection with four corners of the bottom of the movable frame; and the internal threaded holes are formed in the four corners of the interior of the movable frame. By arranging a driving motor,a worm gear speed reducer, a sleeve coupler, a lifting screw rod, a locking nut and a rotary blocking cap, the height of an overhauling platform can be adjusted according to the overhauling requirement, and the driving motor is controlled by the control panel to drive the worm gear speed reducer to act; the worm gear reducer drives the lifting screw to rotate through the sleeve coupler, the locking nut can drive the overhauling platform to conduct height adjusting operation so as to meet the lifting requirement, a good limiting effect can be achieved by the rotary blocking cap, and the liftingstability is guaranteed.
本发明提供一种便于维护的具有防护装置的地铁检修用假台车,包括移动车架,移动脚轮,内螺纹孔,调节螺杆,调节手轮,支撑脚座,检修平台,检修箱,滤杂网和控制面板,所述的移动车架底部四角部位均螺栓连接有移动脚轮;所述的移动车架的内部四角部位均开设有内螺纹孔。本发明驱动电机,蜗轮蜗杆减速器,套筒联轴器,升降螺杆,锁紧螺母和旋转挡帽的设置,有利于根据检修需求进行高度调节检修平台的高度,通过控制面板控制驱动电机带动蜗轮蜗杆减速器动作,使得蜗轮蜗杆减速器通过套筒联轴器带动升降螺杆旋转,即可使得锁紧螺母带动检修平台进行高度调节操作,以满足升降需求,通过旋转挡帽可起到良好的限位作用,保证升降稳定性。
