[0029] Specifically, the motor 3 provides power to drive one rotating shaft 4 to rotate, and transmits power through the synchronization assembly 5 to drive another rotating shaft 4 to rotate synchronously, so that the four sprocket assemblies 6 rotate synchronously.

[0030] The frame 2 is provided with four brush heads 7 , which are in contact with chains of four sprocket assemblies 6 respectively, and the brush heads 7 clean the sprocket assemblies 6 .

[0031] A lifting plate 8 is provided on the chains of the four sprocket wheel assemblies 6 , and four guide wheels 9 are rotatably provided on the lifting plate 8 , and the guide wheels 9 roll on the frame 2 .

[0032] Specifically, four synchronously rotating sprocket assemblies 6 drive the lifting plate 8 to move up and down, and the guide wheel 9 rolls on the frame 2 to maintain the movement stability of the lifting plate 8.

[0033] A door panel 10 is rotatably mounted on the frame 2 , and two ends of a tension spring 11 are connected to the door panel 10 and the frame 2 , respectively.

[0034] The base 1 is provided with an anti-fall frame 12 , and the anti-fall frame 12 is provided with a buffer cylinder 13 . When the lifting plate 8 falls to the lower part of the frame 2 due to failure of the mechanical device, the buffer cylinder 13 buffers the lifting plate 8 .

[0035] The lifting plate 8 is provided with a guide rod 14, on which a slide plate 15 is slidably provided. The telescopic assembly contains multiple groups of telescopic strips 16 and telescopic strips 17. The telescopic strips 16 of each group of telescopic assemblies are hinged to the middle of the telescopic strips 17, and the ends of the telescopic strips 16 and the telescopic strips 17 of adjacent telescopic assemblies are hinged alternately in sequence. The end of the telescopic strip 16 of the first group of telescopic assemblies is hinged to the guide rod 14, the end of the telescopic strip 17 of the first group of telescopic assemblies is hinged to the slide plate 15, and the end of the telescopic strip 2 17 of the last group of telescopic assemblies is hinged to the telescopic plate 18, and the telescopic plate 18 is provided with a slide groove, and the upper hinge shaft of the telescopic assembly slides in the slide groove of the telescopic plate 18.

[0036] The lifting plate 8 is provided with a hydraulic cylinder 19 , and the telescopic shaft of the hydraulic cylinder 19 is connected to the slide plate 15 .

[0037] Specifically, the telescopic shaft of the hydraulic cylinder 19 extends, driving the slide plate 15 to move upward along the guide rod 14, thereby driving the telescopic bar 16 and the telescopic bar 2 17 of the telescopic assembly to rotate, the telescopic assembly extends, and the telescopic assembly drives the telescopic plate 18 to extend. During the extension process of the telescopic plate 18, the upper hinge shaft of the telescopic assembly slides in the slide groove of the telescopic plate 18 to keep the movement of the telescopic plate 18 stable.

[0038] The telescopic plate 18 is provided with four sliding rods 20, the storage plate 21 is slidably provided on the sliding rods 20, the sliding sleeve of the storage plate 21 is slidably provided with a vibration-damping bottom plate 22, the two ends of the vibration-damping spring 23 are respectively connected to the storage plate 21 and the vibration-damping bottom plate 22, the telescopic strip 17 is provided with an unlocking plate 24, the end of the unlocking plate 24 is an arc surface, the arc surface of the unlocking plate 24 is in contact with the lower surface of the vibration-damping bottom plate 22, and the storage plate 21 is used to place goods 29.

[0039] Specifically, when the telescopic assembly is in the extended state, since the unlocking plate 24 rotates with the telescopic bar 17, the arc surface of the unlocking plate 24 is separated from the vibration-damping bottom plate 22, and the vibration-damping bottom plate 22 is placed on the telescopic plate 18, so the sliding sleeve of the storage plate 21 is also in contact with the telescopic plate 18, and the storage plate 21 releases the vibration-damping function, and the storage plate 21 no longer moves up and down, which is convenient for loading and unloading goods 29 on the storage plate 21; when the telescopic assembly is in the retracted state, the arc surface of the unlocking plate 24 lifts the vibration-damping bottom plate 22, so that the vibration-damping bottom plate 22 is separated from the telescopic plate 18, and power is transmitted through the vibration-damping spring 23, so that the storage plate 21 is also lifted, and the sliding sleeve of the storage plate 21 is also separated from the telescopic plate 18, and the storage plate 21 slides on the slide rod 20. The storage plate 21 has a vibration-damping function to prevent the goods 29 from being damaged during transportation.

[0040] The slide plate 15 is provided with a vertical rod 25, a balance frame 26 is provided at the upper end of the vertical rod 25, a pressure plate 27 is slidably provided on the balance frame 26, a boss is provided on the sliding shaft of the pressure plate 27, and both ends of the spring 28 are respectively connected to the bosses on the balance frame 26 and the sliding shaft of the pressure plate 27.

[0041] Specifically, when the slide plate 15 rises, the vertical rod 25 and the balance frame 26 are driven to rise synchronously, so that the pressure plate 27 is separated from the goods 29, which facilitates the removal of the goods 29; when the slide plate 15 descends, the vertical rod 25 and the balance frame 26 are driven to descend synchronously, so that the pressure plate 27 is pressed on the goods 29, and the spring 28 is compressed, thereby preventing the goods 29 from jumping due to mechanical instability during transportation.

[0042] Working principle: The motor 3 provides power to drive a rotating shaft 4 to rotate, and transmits power through the synchronization component 5 to drive another rotating shaft 4 to rotate synchronously, so the four sprocket components 6 rotate synchronously, thereby driving the lifting plate 8 to move up and down, and the guide wheel 9 rolls on the frame 2 to maintain the movement stability of the lifting plate 8.

[0043] When the floor where the cargo 29 needs to be loaded and unloaded is moved, the telescopic shaft of the hydraulic cylinder 19 is extended, driving the slide plate 15 to move upward along the guide rod 14, and the slide plate 15 drives the vertical rod 25 and the balance frame 26 to rise synchronously, so that the pressure plate 27 is separated from the cargo 29, which is convenient for taking out the cargo 29; at the same time, the slide plate 15 drives the telescopic bar 16 and the telescopic bar 21 of the telescopic assembly to rotate, the telescopic assembly is extended, and the telescopic assembly drives the telescopic plate 18 to extend. During the extension process of the telescopic plate 18, the telescopic plate 18 drives the door panel 10 to rotate, and the tension spring 11 is stretched to automatically open the door panel 10; when the telescopic plate 18 is extended, since the unlocking plate 24 rotates with the telescopic bar 21, the arc surface of the unlocking plate 24 is separated from the vibration-damping bottom plate 22, and the vibration-damping bottom plate 22 is placed on the telescopic plate 18, the sliding sleeve of the storage plate 21 is also in contact with the telescopic plate 18, and the storage plate 21 releases the vibration-damping function, and the storage plate 21 no longer moves up and down, which is convenient for loading and unloading cargo 29 on the storage plate 21.

[0044] The telescopic shaft of the hydraulic cylinder 19 contracts, driving the slide plate 15 to move downward along the guide rod 14, the telescopic assembly contracts, and the arc surface of the unlocking plate 24 lifts the vibration-damping bottom plate 22 to separate the vibration-damping bottom plate 22 from the telescopic plate 18. The power is transmitted through the vibration-damping spring 23, so that the storage plate 21 is also lifted, and the sliding sleeve of the storage plate 21 is also separated from the telescopic plate 18. The storage plate 21 slides on the slide rod 20. The storage plate 21 has a vibration-damping function to prevent the goods 29 from being damaged during transportation; at the same time, the slide plate 15 drives the vertical rod 25 and the balance frame 26 to descend synchronously, so that the pressure plate 27 is pressed on the goods 29, and the spring 28 is compressed, thereby preventing the goods 29 from jumping due to mechanical instability during transportation.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
