DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 and Figure 3 A rail trolley with a multi-directional loading mechanism is shown, comprising a rail trolley body 1, with lifting wheels 2 for lifting rails installed on the upper ends of the two side walls of the rail trolley body 1, and a left electric-controlled flip frame 3 and a right electric-controlled flip frame 4 are movably installed on the lower surface of the rail trolley body 1 through mounting brackets on both sides, and gravity hooks 5 are movably installed inside the left electric-controlled flip frame 3 and the right electric-controlled flip frame 4, and an electric-controlled wrapped loading module 6 is installed on the lower surface of the rail trolley body 1 inside the left electric-controlled flip frame 3 and the right electric-controlled flip frame 4.

[0030] Working principle: When the side loading method is adopted, the left electric-controlled flip frame 3 turns to the left, and the right electric-controlled flip frame 4 turns to the right. At this time, the goods are loaded on the packaging bag, and then the packaging bag is mounted on the gravity hook 5 for side loading; when the bottom loading method is adopted, a wrapping storage bag is formed at the lower end of the rail trolley body 1 by pulling the electric-controlled wrapping loading module 6, so that the goods can be directly loaded inside without the packaging bag, and then bottom loading and transportation are carried out.

[0031] In order to cooperate with the lateral movable assembly, the left electric-controlled flip frame 3 and the right electric-controlled flip frame 4 both include a flip frame 341 movably mounted on a mounting bracket and an embedded lateral adjustment support rod 342 mounted on the lower surface of the rail trolley body 1.

[0032] In order to facilitate internal assembly, a longitudinal assembly frame 343 is staggered and fixed inside the flip frame 341 .

[0033] In order to cooperate with the movable assembly, the gravity hook 5 is movably connected to the longitudinal assembly frame 343 through the assembly axes on both sides of the connection end.

[0034] When the left electric-controlled flip frame 3 and the right electric-controlled flip frame 4 flip outward, the gravity hook 5 flips outward, and an inclined hanging mechanism is formed outside the left electric-controlled flip frame 3 and the right electric-controlled flip frame 4. At this time, the handle on the packaging bag can be hung on the gravity hook 5, and the materials can be loaded in a hanging manner.

[0035] The unloading method is to flip the rail trolley body 1 to one side, so that the packaging bag will slip off the gravity hook 5 to complete the separation operation.

[0036] In order to facilitate lateral storage, a left storage groove is opened on the lower surface of the track trolley body 1, located inside the connection end of the left electric control flip frame 3, and a right storage groove is opened on the lower surface of the track trolley body 1, located inside the connection end of the right electric control flip frame 4.

[0037] In order to cooperate with the lateral storage and winding adjustment, the electrically controlled wrapping loading module 6 includes a horizontal curtain roller 61 fixedly installed inside the left storage slot, a horizontal rope drum 62 fixedly installed inside the right storage slot, a horizontal curtain shaft 63 elastically installed inside the horizontal curtain roller 61 through springs on both sides, an electrically controlled driving shaft 64 installed inside the horizontal rope drum 62, a wrapping curtain 65 wound on the horizontal curtain shaft 63 and an elastic pull cord 66 wound on the electrically controlled driving shaft 64.

[0038] The outer end of the elastic cord 66 is connected to the outer end of the wrapping curtain 65.

[0039] In order to lock the angle of the horizontal rolling shutter shaft 63 , a self-locking switch 7 is installed on the outer side of the rail trolley body 1 at a position corresponding to the horizontal rolling shutter shaft 63 .

[0040] After pulling the wrapping curtain 65 outward according to the size of the goods, the self-locking switch 7 can be inserted into the rail trolley body 1, and then it will be inserted into the limit groove outside the horizontal rolling curtain shaft 63. At this time, the horizontal rolling curtain shaft 63 cannot rotate, ensuring safety and facilitating the separation of the wrapped objects.

[0041] The separation method is to control the electronically controlled drive shaft 64 to release the elastic cord 66 outward, and then the right side of the wrapped curtain 65 is opened and falls from the right side opening, thereby completing the unloading operation.

[0042] In order to limit the front and rear ends, limit hooks 8 are provided on the front and rear side walls of the left electric-controlled flip frame 3 and the right electric-controlled flip frame 4, and lateral limit cover cloths 9 are detachably connected to the limit hooks 8.

[0043] When the electrically controlled wrapping loading module 6 wraps the goods, there will be openings at the front and rear ends, which may fall off from the openings during transportation. At this time, it is necessary to put the connecting ropes on both sides of the lateral limiting cover cloth 9 on the limiting hooks 8. At this time, the goods will be limited on both sides to ensure the safety of the goods.

[0044] In order to adjust the center of gravity and ensure stability during operation, a built-in guide rail 10 is fixedly installed inside the flip frame 341, an electrically controlled adjustment slider 11 is installed inside the built-in guide rail 10, and a detachable counterweight block 12 is fixedly installed on the outer surface of the electrically controlled adjustment slider 11.

[0045] The purpose of adjusting the center of gravity is that when the rail trolley is fully loaded with goods, once the goods on one side are separated, in order to ensure the stability of the rail trolley, the electrically-controlled adjusting slider 11 on the idle side needs to drive the detachable counterweight block 12 on its outer side to descend, while the electrically-controlled adjusting slider 11 on the loaded side needs to drive the detachable counterweight block 12 on its outer side to rise.

[0046] In order to guide and limit the elastic rope 66 as required, a limiting cylinder 13 with a lateral opening is installed on the inner side of the right electric-controlled flip frame 4.

[0047] The elastic cord 66 is inserted into the interior of the limiting cylinder 13 from the lateral opening, so that the elastic cord 66 can be attached to the inner side of the right electric-controlled flip frame 4 .

[0048] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
