Self-tilting semi-trailer

Abstract

The invention relates to a self-tipping semi-trailer which comprises a frame, axles, an electric system and an air circuit system, wherein the frame is connected with the axles, and the electric system and the air circuit system are used for controlling power. A slippage device is arranged among the frame and the axles and comprises a guide rail, a sliding rail, positioning blocks and fixing pins, the guide rail and the sliding rail are connected with each other, the positioning blocks are arranged at two ends of the sliding rail, the fixing pins are used for fixing the guide rail and the sliding rail, the sliding rail is welded at the bottom of the frame, and the axles are fixed at the bottom of the guide rail. The self-tipping semi-trailer realizes larger inclination magnitude as compared with a frame directly inclined at the same height by a simple optimized structure, cargos are more conveniently and rapidly loaded and unloaded, a bearing platform and the cargos can be smoothly stressed and cannot be damaged due to impact, safety of the cargos, the semi-trailer and workers in the cargo loading and unloading process is guaranteed, loading and unloading efficiency and transporting efficiency are sufficiently improved, the cost of manpower and material resources is saved, and the self-tipping semi-trailer is applicable to the field of cargo loading, unloading and transporting, and particularly suitable for popularization and application in relevant fields of wreckers, emergency service vehicles and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for loading, unloading and carrying goods, in particular to a self-tilting semi-trailer. Background technique [0002] At present, in order to improve transportation efficiency, semi-trailers are widely used as supplementary equipment on various vehicles. Among them, the main methods of loading and unloading goods on semi-trailers are as follows: (1) Ordinary goods are carried manually. , load the goods with a crane, and unload them with a crane after reaching the destination; (2) There is a springboard at the rear of the semi-trailer. The vehicle can drive on the semi-trailer by itself, but due to the limited length of the springboard, the angle of the slope formed is relatively large, which is not conducive to the up and down of the vehicle, especially when changing from the springboard to the platform, it is especially not conducive to vehicle loading and unloading; (3) for For sm...

[0002] At present, in order to improve transportation efficiency, semi-trailers are widely used as supplementary equipment on various vehicles. Among them, the main methods of loading and unloading goods on semi-trailers are as follows: (1) Ordinary goods are carried manually. , load the goods with a crane, and unload them with a crane after reaching the destination; (2) There is a springboard at the rear of the semi-trailer. The vehicle can drive on the semi-trailer by itself, but due to the limited length of the springboard, the angle of the slope formed is relatively large, which is not conducive to the up and down of the vehicle, especially when changing from the springboard to the platform, it is especially not conducive to vehicle loading and unloading; (3) for For small road rescue vehicles, in order to load the immobile vehicle on the rescue vehicle, the platform of the rescue vehicle is usually tilted backward directly under the action of the hydraulic cylinder, and the rear end touches the ground to form a slope, so that the vehicle to be rescued can be loaded on the rescue vehicle. However, since the flat plate is tilted as a whole and the axle is close to the rear of the vehicle, the angle of the formed slope is relatively large, which is the same as the above method (2), and this method is also not conducive to loading and unloading the rescued vehicle.
