The invention discloses a limiting device for parking of a heavy vehicle. A traveling wheel set of the device is arranged on the bottom face of a movable trolley in a liftable mode, a lifting mechanism is arranged on the movable trolley and drives the traveling wheel set to stretch out of or retract into the bottom face of the movable trolley, sliding rails are arranged on the side face of the movable trolley in the advancing direction, sliding grooves are formed in the side face of a left limiting block and the side face of a right limiting block, the sliding grooves are formed in the sliding rails, the left limiting block and the right limiting block can move along the sliding rails correspondingly, a left rotating lead screw and a right rotating lead screw are erected on the top face of the movable trolley, a left lead screw sliding block and a right lead screw sliding block are in threaded connection with the left and right rotating lead screws correspondingly and fixedly connected with the side faces of the left limiting block and the right limiting block correspondingly, and an adjusting rotating rod is arranged on the top face of the movable trolley and drives the left and right rotating lead screws to rotate. The limiting device overcomes the defect that a traditional heavy vehicle is parked through a wedge-shaped limiting block, is simple in structure and convenient to operate, effectively limits front-back sliding of the heavy vehicle when the heavy vehicle is parked, avoids vehicle sliding accidents, and ensures the parking effect of the vehicle.

    本发明公开了一种用于重型车辆驻停的限位装置,本装置的行驶轮组可升降设于移动台车底面,升降机构设于移动台车并且驱动行驶轮组伸出或缩进移动台车底面,滑轨设于移动台车行进方向侧面,左限位块和右限位块侧面设有滑槽,并且滑槽设于滑轨使得左限位块和右限位块分别沿滑轨移动,左右旋丝杆架设于移动台车顶面,左丝杆滑块和右丝杆滑块分别螺接左右旋丝杆,并且左丝杆滑块和右丝杆滑块分别固定连接左限位块和右限位块侧面,调节旋杆设于移动台车顶面并且驱动左右旋丝杆旋转。本限位装置克服传统重型车辆采用楔形限位块驻停的缺陷,其结构简单,操作方便,有效限制重型车辆停放时的前后滑移,避免溜车事故,确保车辆的驻停效果。
