Cargo transportation fixing device based on principle of thermal expansion and cold contraction

Abstract

The invention relates to the technical field of freight transportation and discloses a cargo transportation fixing device based on the principle of thermal expansion and cold contraction. Metal platesare movably connected to the bottom end of a body, supporting pieces are movably connected to the front ends of the corresponding metal plates, hydraulic pipes are movably connected to the back facesof the corresponding supporting pieces, and a mounting base is fixedly connected to the top end of a supporting frame. By adopting the cargo transportation fixing device based on the principle of thermal expansion and cold contraction, an inserting rod is inserted into an iron tray for supporting goods, gears are adjusted with hands to enable the goods to be inclined backwards to form a certain angle with each supporting piece, a hydraulic oil tank at the right end of each metal plate operates along with the goods under the action of downward pressure, the inserting rod can be abutted againsta starting rod to move upwards when ascending, a spike tooth plate operates along with the starting rod due to the influence of the linkage effect, bayonet locks on the spike tooth plate clamp the goods, and horizontal gears are pressed downwards and drive the bayonet lock at the top end to operate, so that the problem that the goods are prone to losing the gravity center due to misoperation of an operator and then topple or move is solved, the problem that people is prone to being hurt by movement of the goods, and great potential safety hazards exist is solved, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field of freight transportation, in particular to a cargo transportation fixing device based on the principle of thermal expansion and cold contraction. Background technique [0002] Cargo transportation, referred to as freight, refers to the movement of items in space with the help of transport capacity. Specifically, transportation realizes the physical transfer of the space position of items and realizes the space utility of logistics. Forklifts are a common short-distance logistics transportation The handling device is mainly composed of frame, driving platform, walking wheel, fork frame and hydraulic device. When working, the fork frame holds up the goods for short-distance transportation and mechanized loading and unloading. This transportation method saves time and effort. High efficiency and low cost. [0003] However, in real life, because there is no effective fixing device on the forklift forklift, dur...
