As there is no top cover for the grating semi-trailer, in order to prevent rain, it generally needs to be covered with a tarpaulin. It usually requires the cooperation of multiple people at the same time, which is also time-consuming and laborious.
In addition, according to the requirements of GB7258-2017, starting from January 1, 2020, the traditional three-axle fence type and warehouse fence semi-trailer must be installed with disc brake axles and air suspension, which is very difficult for traditional warehouse fences. It is undoubtedly a big blow for a car. After adding disc brakes and air suspension, the purchase cost of a three-axle warehouse car will increase significantly, and the market competitiveness will decline rapidly.

The invention relates to a semitrailer capable of being opened from three sides. The semitrailer comprises a frame system, a compartment arranged on the frame system and a walking system arranged below the frame system. The compartment comprises a front compartment system, a rear compartment system, a side compartment system connected with the front compartment system and the rear compartment system, a ceiling system arranged above the front compartment system, the rear compartment system and the side compartment system, and a bottom plate arranged at the bottom of the front compartment system, the bottom of the rear compartment system and the bottom of the side compartment system. The side compartment system and the ceiling system can be opened or closed in a reciprocating mode in the direction from the front compartment system to the rear compartment system. The side compartment system and the ceiling system can be controlled to be opened or closed, so that independent or combined opening of the semitrailer compartment in the scheme can be achieved on three sides, flexible cargo loading and unloading of the semitrailer compartment are facilitated, the compartment does not need tobe jacked up, and the cost and difficulty of adding related equipment are greatly reduced.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a semi-trailer that can be opened on three sides. Background technique [0002] At present, when loading and unloading the main warehouse grid semi-trailer of road transportation, there are certain limitations in the opening angle and range of the door, and the efficiency of loading and unloading is low, which seriously restricts the normal attendance rate of users. Since the grate semi-trailer has no top cover, in order to prevent rain, it generally needs to be covered with a tarpaulin. It usually requires the cooperation of multiple people at the same time, which is also time-consuming and laborious. In addition, according to the requirements of GB7258-2017, starting from January 1, 2020, the traditional three-axle fence type and warehouse fence semi-trailer must be installed with disc brake axles and air suspension, which is very difficult for traditional warehouse fences. It is un...
