Limiting device for parking of heavy vehicle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a limiting device for parking heavy vehicles. Background technique [0002] Usually, when heavy vehicles are parked for maintenance, the parking of the vehicle is generally realized by placing wedge-shaped stoppers before and after the tires. Carrying out vehicle parking limit in the above-mentioned way has bigger drawbacks. One is that the negligence of the operator may only limit the movement of the vehicle in one direction when the wedge-shaped limit block is placed, which may cause the vehicle to slip in another direction, resulting in a vehicle collision accident. Second, when the size of the wedge-shaped limit block is small and the vehicle is parked on a large slope, the limit may fail due to the heavy weight of the vehicle, and the vehicle tires cross the wedge-shaped limit block, thereby causing a rolling accident.

Problems solved by technology

One is that when the wedge-shaped limit block is placed, due to the negligence of the operator, it may only limit the movement of the vehicle in one direction, which may cause the vehicle to slip in the other direction, resulting in a vehicle collision accident

The second is that when the size of the wedge-shaped limit block is small and the vehicle is parked on a large slope, the limit may fail due to the heavy weight of the vehicle, and the vehicle tires pass over the wedge-shaped limit block, resulting in a rolling accident
