Disclosure of Invention

The invention aims to provide a self-loading and self-unloading device of a freight automobile, which aims to solve the problems in the background technology that: special loading and unloading equipment needs to be configured, a suitable place needs to be provided, and professional personnel need to be equipped, so that loading and unloading can not be carried out at any time and anywhere by a freight vehicle, the logistics efficiency is low, and the loading and unloading cost is high. The technical scheme for solving the technical problem is as follows: a self-loading and self-unloading device of a freight automobile is characterized in that: the two ends of the fixed crane beam are connected with a rotary crane beam which can be horizontally turned up and locked or put down and locked, the upper end beams and the lower end beams of the stand columns are arranged above and below the four stand columns which are symmetrical front and back and left and right and are respectively connected with the upper end and the lower end of the adjacent stand column, the upper parts of the four stand columns which are symmetrical front and back and left and right are connected with a lifting stand column, the top end of the lifting stand column is connected with the fixed crane beam, an electric lifter is connected with the lifting stand column to drive the lifting stand column to lift along a linear slide rail, guide wheels connected with the bottom ends of the four stand columns slide along guide rails arranged on a carriage bottom plate, and the crane moves along. The two ends of the fixed crane beam are connected with the rotary crane beam which can be horizontally turned up and locked or put down and locked through hinges, the L-shaped stop plate is horizontally connected with the crane beam connecting plate through bolts, and the L-shaped stop plate is vertically connected with the rotary crane beam which can be horizontally turned up and locked or put down and locked through bolts, so that the locking in the put-down state is realized. After the L-shaped stop plate is disassembled, the rotary crane beam capable of being horizontally turned up and locked or put down and locked is horizontally turned up through the hinge, and the screw hole in the crane beam connecting plate is vertically matched with the screw hole in the rotary crane beam capable of being horizontally turned up and locked or put down and locked and is locked by the bolt, so that the turning-up state is locked.

Compared with the prior art, the invention has the advantages that: by adopting the technical scheme, when unloading or loading, firstly, the electric lifter is controlled to drive the lifting upright post to lift along the linear slide rail, the height of the upright post is increased to be higher than that of the container, then the L-shaped stop plate is used for preventing the lifting upright post from swinging at ordinary times and rotating the crane beam in a laid-down state, the crane beam is turned up through the hinge and is coaxial with and fixed with the fixed crane beam, so that the crane beam is lengthened to the outside of the container body, the crane is controlled to move along the lengthened crane beam, and when loading and unloading, goods are hoisted from the side surface of the freight car by the crane and are placed on the car or are placed on the ground from the car, and the loading and; the guide wheels connected with the bottom ends of the four upright posts slide along guide rails arranged on the bottom plate of the carriage, so that the loading and unloading operation covers the goods loading position of the whole vehicle body. Therefore, goods can be loaded and unloaded at any time and any place by the aid of the freight car, the goods are unloaded and loaded without professional hoisting equipment, efficiency is improved, and manpower and material resources are obviously saved.
