[0028] 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.

[0029] 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.

[0030] Figure 1 , Figure 2 and Figure 3 A multi-layer conveyor-type four-way vehicle used for four-way vehicle rack transportation is shown, comprising a main frame 1, an electrically-controlled overhead cargo platform 2 is installed on the upper surface of the main frame 1, lateral storage grooves 3 are symmetrically opened on the side walls around the main frame 1, and an electrically-controlled telescopic frame 4 is movably installed inside the lateral storage groove 3, and an electrically-controlled flip support arm 5 and an electric drive wheel 6 installed on the outer end of the electrically-controlled flip support arm 5 are movably installed inside the electrically-controlled telescopic frame 4.

[0031] Working principle: the electrically controlled telescopic frame 4 extends outward, and then controls the electrically controlled flip support arm 5 to flip downward, the electric drive wheel 6 contacts the ground or the bottom of the track, and lifts the main frame 1, so that the main frame 1 can translate normally. When cargo is needed, the electrically controlled overhead cargo platform 2 is flipped, and then the cargo slides onto the electrically controlled overhead cargo platform 2, the electrically controlled overhead cargo platform 2 flips and resets, and the main frame 1 controls the transportation to move the cargo to the designated position, and then the cargo on the surface of the electrically controlled overhead cargo platform 2 is removed for easy unloading.

[0032] In order to cooperate with flipping and adjustment, the electrically controlled overhead cargo platform 2 includes a support platform 21 installed on the upper surface of the main frame 1 and four upper adjustment struts 22 for controlling the flipping and lifting of the support platform 21 .

[0033] Two upper adjustment struts 22 are respectively arranged on both sides of the main frame 1 , and the angle of the support platform 21 is adjusted by telescoping the upper adjustment struts 22 on different sides.

[0034] When the upper adjustment struts 22 on both sides are extended at the same time, the height of the support platform 21 is raised; when the upper adjustment struts 22 on one side are extended and the upper adjustment struts 22 on the other side remain unchanged, the angle of the support platform 21 is flipped.

[0035] In order to cooperate with the lateral telescopic adjustment, a lateral telescopic groove for installing the electric-controlled telescopic frame 4 is opened on the inner side of the lateral receiving groove 3.

[0036] In order to cooperate with telescopic adjustment, the electrically controlled telescopic frame 4 includes a telescopic adjustment frame 41 slidably inserted into the lateral telescopic groove, a horizontal electrically controlled screw rod 42 movably installed in the lateral telescopic groove, two internally threaded adjustment seats 43 threadedly sleeved on the horizontal electrically controlled screw rod 42, and a control connecting rod 44 movably installed between the telescopic adjustment frame 41 and the internally threaded adjustment seat 43.

[0037] The horizontally placed electric control screw 42 controls the internal thread adjustment seats 43 on both sides to move in opposite directions by rotating, and compresses the control connecting rod 44 by moving, and then the control connecting rod 44 is used to compress the telescopic adjustment frame 41 outwards, thereby controlling its telescopic adjustment.

[0038] In order to cooperate with the flipping adjustment, the electrically controlled flipping support arm 5 includes a flipping support arm 51 axially movably installed inside the telescopic adjustment frame 41 and an inner side adjustment support rod 52 for controlling the flipping support arm 51 .

[0039] The inner adjustment support rod 52 controls the flip support arm 51 to perform flip adjustment by telescoping, and then forms a lateral support mechanism on the outer side of the main frame 1.

[0040] In order to cooperate with electric conveying, a strip transmission opening is opened on the support platform 21, and an electrically controlled conveyor belt 7 is installed on the upper surface of the main frame 1 at a position corresponding to the strip transmission opening.

[0041] When the support platform 21 is lifted, the electric-controlled conveyor belt 7 will be completely covered, and it will be in a supporting state at this time; and when the support platform 21 is lowered, the upper end of the electric-controlled conveyor belt 7 will be exposed, so that the goods can be transported horizontally by the electric-controlled conveyor belt 7.

[0042] In order to cooperate with the top sliding adjustment, a top adjustment slide groove 8 with an opening on one side is provided on the upper surface of the support platform 21, and an electric control extension plate 9 is slidably mounted inside the top adjustment slide groove 8.

[0043] In order to cooperate with the translational extension and facilitate the import of goods from the ground to the support platform 21, the lower surface of the support platform 21 is located at the lower end of the top adjustment slide 8 and is fixedly equipped with a lateral assembly frame 10. The electrically controlled extension plate 9 includes a sliding extension plate 91 slidably installed inside the top adjustment slide 8, an internal threaded adjustment block 92 fixed on the inner wall of the sliding extension plate 91, and an inner adjustment screw 93 movably installed inside the lateral assembly frame 10.

[0044] The inner adjusting screw 93 rotates to control the inner thread adjusting block 92 to adjust, thereby controlling the sliding extension plate 91 to slide and adjust inside the top adjusting slot 8. Then people can pile up the goods on the sliding extension plate 91, and then lift them onto the support platform 21 through the sliding extension plate 91.

[0045] In order to cooperate with monitoring the inner wall of the guide rail, a distance sensor module 11 for detecting the external distance is installed on the outer side surface of the telescopic adjustment frame 41.

[0046] The distance sensor module 11 can monitor the inner wall of the guide rail from the outside, and at this time, the electrically controlled telescopic frame 4 can be controlled to extend outward to avoid excessive extension.

[0047] In order to monitor the quality, deflection position, and loading and unloading status of the goods, gravity sensor modules 12 are installed on both sides of the upper surface of the support platform 21 .

[0048] By installing gravity sensor modules 12 at the flip ends on both sides of the support platform 21, the goods loaded on the upper end can be weighed. When the goods are placed at an angle, the support platform 21 can be controlled to descend, and then the electrically controlled conveyor belt 7 protruding outward can be used for translation control; when loading and unloading of materials is required, the gravity sensor module 12 at the low end is used to monitor the state of unloading, and then the device is controlled to reset; and the gravity sensor module 12 at the high end is used to monitor the state of loading, and then the device is controlled to reset.

[0049] 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.
