Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to a closed compartment that can be quickly assembled and unassembled. Background Art
[0002] Due to their structural characteristics, enclosed carriages are safer and more aesthetically pleasing than conventional open-top trucks, and they protect cargo from getting wet in the rain. To improve transport efficiency and reduce costs, these carriages are becoming increasingly longer (currently up to 10 meters), making loading and unloading inconvenient.
[0003] To improve cargo loading and unloading efficiency, a hydraulic tailgate has been added to the rear of the carriage to lift cargo flush with the carriage floor. While this solves the problem of lifting and lowering cargo, it still requires horizontal handling, with a maximum length of approximately 10 meters. If the cargo is larger than the hydraulic tailgate's load surface (approximately 2.5 meters square) or heavier than the tailgate's load capacity, the hydraulic tailgate cannot be used for lifting and lowering, requiring manual loading and unloading. Utility Model Content
[0004] In response to the defects in the existing technology, the purpose of the utility model is to provide a closed carriage that can be quickly loaded and unloaded. The loading and unloading of goods is completed by hoisting through a device on the top of the carriage. It is suitable for a wider range of cargo sizes and weights, and can improve efficiency compared to manual handling and hydraulic tailgate loading and unloading.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a closed car body for quick loading and unloading, comprising a car body arranged on a chassis beam, the car body comprising a bottom plate, a front plate, a rear plate, two side plates and a top plate, and also comprising a loading and unloading device arranged in the car body, the loading and unloading device comprising two supporting longitudinal beams, a sliding bracket, an oil cylinder and a lifting mechanism; the two supporting longitudinal beams are fixedly arranged on the bottom surface of the top plate, and first longitudinal slide grooves are respectively provided on opposite sides of the two supporting longitudinal beams; the two sides of the sliding bracket are respectively slidably arranged in the corresponding first longitudinal slide grooves; the oil cylinder is connected to the sliding bracket for driving the sliding bracket to move longitudinally; the lifting mechanism is arranged at the bottom of the sliding bracket and can move longitudinally along the sliding bracket.
[0006] A further improvement is that the cross section of the supporting longitudinal beam is C-shaped, a plurality of first pulleys adapted to the first longitudinal sliding grooves are provided on both sides of the sliding bracket, and each first pulley is connected to the sliding bracket via a rotating shaft.
[0007] A further improvement is that the length of the sliding bracket is adapted to the length of the top plate, both being L, and the maximum extension distance of the sliding bracket is L / 2.
[0008] A further improvement is that a first connecting seat is provided in the middle of the top surface of the sliding bracket, a second connecting seat is provided at the front end of the bottom of the top plate, the piston rod of the oil cylinder is connected to the first connecting seat, and the cylinder body of the oil cylinder is connected to the second connecting seat.
[0009] Further improvements are: a connecting longitudinal beam is fixedly provided in the middle of the bottom surface of the sliding bracket, the cross-section of the connecting longitudinal beam is I-shaped, and a second longitudinal slide groove is formed on both sides of the connecting longitudinal beam; the lifting mechanism includes a trolley, both sides of the trolley extend upward to form a connecting arm, and the connecting arm is provided with a second pulley adapted to the second longitudinal slide groove, and an electric hoist is provided at the bottom of the trolley.
[0010] A further improvement is that columns are arranged on the left and right sides of the box body to form a supporting frame.
