Description

Technical Field

[0001] This invention belongs to the field of loading and transportation technology, and specifically relates to an automatic loading and unloading storage box. Background Technology

[0002] In the transportation sector, there are often pieces of equipment, such as generator sets and batteries, that require frequent loading and unloading and need to be properly protected. These devices are typically stored in protective containers, and loading and unloading are primarily done manually.

[0003] A container, disclosed in CN107934254A, includes a container body and an internal lifting device disposed inside the container body. The internal lifting device includes two end beam guide rails respectively installed on the top of the container body. A crossbeam guide rail, slidable relative to the end beam guide rails, is transversely arranged in the guide rail grooves of the two end beam guide rails. A sliding trolley is installed in the guide rail groove of the crossbeam guide rail, and a lifting hoist is mounted on the sliding trolley. A first sliding drive unit of the crossbeam guide rail, a second sliding drive unit of the sliding trolley, and a lifting drive unit of the lifting hoist are respectively connected to a control handle signal. This invention provides a container for loading cargo. However, the door is located on the side of the container body, and the lifting hoist can only ensure the movement of cargo inside the container; moving cargo from the outside to the inside still requires manual labor.

[0004] The shortcomings of existing technology are that traditional cargo boxes are mostly handled manually by carrying goods into the box and then loading the box onto a transport vehicle. During the entire handling and transportation process, the goods inside the box are very easy to be damaged by collisions, resulting in poor protection and high transportation costs. Summary of the Invention

[0005] To address the aforementioned problems, the present invention aims to provide an automatic loading and unloading storage box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic loading and unloading storage box, comprising a box body, a crossbeam and a motor installed at the top of the box body, pulleys installed on the crossbeams, and a winding wheel for use with the pulleys installed on the motor; load-bearing beams are respectively installed at both ends of the top of the box body, guide rails are provided on the outer side of the load-bearing beams, and rollers are installed in the guide rail grooves of the guide rails; electric cylinders for opening or closing the bottom gate of the box body are also provided on both sides of the box body.

[0007] The enclosure is a sealed structure. The gate is divided into a first gate and a second gate, which are located at the bottom of the enclosure and are sealed together with the enclosure. Symmetrical positioning seats are installed at the closing points of the first gate and the second gate.

[0008] The pulley is fitted in the middle of the crossbeam, and the winding wheel is mounted on the motor shaft. Both the winding wheel and the pulley have a cylindrical structure in the middle and vertical discs at both ends. A hole is opened in the upper part of the box, and the hole, the cylinder of the winding wheel and the cylinder of the pulley are on the same central axis.

[0009] The winding reel has a coil of wire wound around it, and the wire is fed along the pulley direction and passes through the hole in the upper part of the box.

[0010] The load-bearing beams at both ends of the top of the box are connected by crossbeams. The load-bearing beams are installed on the side plates on both sides of the box, and the roller axles pass through the load-bearing beams to fix the rollers.

[0011] The number of rollers is three on each side and they are symmetrical to each other.

[0012] The side panel is a right-angled trapezoidal three-dimensional structure. The right-angled side of the bottom of the side panel is placed against the right-angled side of the box body. The rectangular surface of the side panel connecting the top and bottom is on the same horizontal plane as the top of the box body. Two side panels are installed on each side of the box body.

[0013] The guide rail is a rectangular structure with grooves and can be installed on transportation equipment.

[0014] The electric cylinder is assembled from a servo motor and a lead screw. One end of the servo motor is fixed in the middle of the two side plates, and the other end is connected to the lead screw. The lead screw and the connecting rod are connected at an acute angle, and the connecting rod is fixed on the door.

[0015] It also includes a locking pin (11) for engaging with the positioning seat to lock the first and second gates.

[0016] Compared with existing technologies, this invention has the following advantages: diverse functions and automation. By fixing the guide rail to the transport equipment and using rollers on both sides of the storage box, the storage box can be moved horizontally, allowing for changes in its spatial position and facilitating the loading, unloading, and use of the equipment inside. Electric cylinders on both sides of the storage box enable the opening and closing of the bottom gate, facilitating automatic loading and unloading of the equipment. The locking pins enhance the load-bearing capacity during storage. Pulleys, a motor, and a take-up reel are used to automatically load and unload the stored equipment via a pull rope. The enclosed storage box provides protection for the equipment inside. Attached Figure Description
