Primary-secondary transport trailer and use method

Abstract

The invention belongs to the technical field of semitrailer production, and particularly relates to a primary-secondary transport trailer and a use method. The primary-secondary transport trailer comprises a primary trailer and a secondary trailer matched with a compartment of the primary trailer, a vertical front compartment plate is arranged at the front end of a compartment bottom plate of the primary trailer, and a turnover hydraulic ladder stand capable of bearing the secondary trailer is arranged at the rear end of the compartment bottom plate of the primary trailer; a radar range finder is arranged on the front compartment plate corresponding to the head side of the secondary trailer, an audible and visual alarm and a voice alarm are arranged on the top of the front compartment plate, and a plurality of wheel limiting grooves corresponding to wheels of the secondary trailer are formed in the compartment bottom plate of the primary trailer. A pair of front limiting assemblies and a pair of rear limiting assemblies are arranged at the front end and the rear end of the compartment bottom plate of the primary trailer respectively, the front limiting assemblies are used for preventing the secondary trailer from moving forwards in the transportation process, and the rear limiting assemblies are used for preventing the secondary trailer from moving backwards in the transportation process. The device can ensure the safety of the secondary trailer during loading, unloading and transportation, and loading and unloading of the secondary trailer can be efficiently and flexibly realized under the condition of no loading platform.

Description

technical field [0001] The invention belongs to the technical field of semi-trailer production, and in particular relates to a mother-child transport trailer and a use method. Background technique [0002] Trailer is an important type of vehicle for road transportation, and goods such as coal, steel or wood all need trailers for transportation. After the trailer truck arrives at the destination and unloads the cargo, due to the high stagnation cost of the vehicle during the return distribution waiting time or no cargo to be transported, the trailer often returns empty-loaded, and the empty-load operation of the trailer consumes fuel and tolls, resulting in logistics problems. The operating cost is high, and the child-mother transport trailer came into being. However, the existing child-mother transport trailer requires a special loading platform to place the child trailer into the mother trailer, and the driver does not operate properly, which is very prone to safety acciden...

Problems solved by technology

After the trailer truck arrives at the destination and unloads the cargo, due to the high stagnation cost of the vehicle during the return distribution waiting time or no cargo to be transported, the trailer often returns empty-loaded, and the empty-load operation of the trailer consumes fuel and tolls, resulting in logistics problems. The operating cost is high, and the child-mother transport trailer came into being. However, the existing child-mother transport trailer requires a special loading platform to place the child trailer into the mother trailer, and the driver does not operate properly, which is very prone to safety accidents. In addition, the position limit of the sub-trailer in the parent trailer is not firm, and it is easy to shake, which reduces the safety of transportation. Therefore, it is urgent to improve
