[0015] Technical effects and advantages of the present invention:

[0016] 1. The equipment of the present invention is placed in front of the existing docking platform, i.e., the concrete structure table surface, and ensures that the top of the transfer platform component is on the same plane as the concrete table surface, and can load and unload goods from trucks of normal height, and can expand the concrete table surface to a certain extent, which is convenient for loading and unloading trucks.

[0017] 2. In the process of loading and unloading goods on a truck with a high height, the present invention first drives the threaded rod to rotate through the operation of the servo motor, and then drives the two push plates to approach, and then drives the two first U-shaped fixed plates to approach the middle, so that the rotating rod rotates along the positioning pin, so that the angle between the two rotating rods changes, and under the positioning of the sliding bar by the limiting slide rail, the second U-shaped fixed plate and the sliding bar can only translate along the limiting slide rail, so that the plane where the second U-shaped fixed plate and the top of the sliding bar are located rises, and then the transfer platform assembly rises so that the plane where the transfer platform assembly is located is on the same plane as the bottom of the truck compartment, which is convenient for completing the loading and unloading of goods on trucks of different heights.

[0018] 3. In the process of the transfer platform assembly rising when the servo motor is working, the second U-shaped fixing plate on one side will push the fourth fixing plate to approach the center of the transfer platform assembly, and then when the hydraulic cylinder is not working, that is, the length of the hydraulic rod does not change, the fourth fixing plate approaches the guide assembly to push the fixing rod, the hydraulic cylinder, and the hydraulic rod to tilt at an angle, and then rotate under the positioning of the first rotating positioning shaft and the second rotating positioning shaft, thereby pushing the second positioning assembly to move toward the back, and then driving the sliding block to move toward the back, and after moving to the back of the guide groove of the second guide rail, the second guide rail and the second limiting plate will be pushed to move on the inner side of the first guide rail, and then the second fixed seat, the third fixing plate and the second table will be driven to move toward the back, and then the platform on the top of the transfer platform assembly will be unfolded to expand the operating area on the top of the equipment, so as to facilitate the loading and unloading of trucks, and avoid the need for frequent lifting of the equipment to complete the transfer of goods on the top of the transfer platform assembly during the loading and unloading process, thereby increasing the loading and unloading efficiency of the trucks.

[0019] 4. In the present invention, when the transfer platform assembly does not need to be raised to the highest position, the second U-shaped fixing plate pushes the fourth fixing plate to move a short distance, and the unfolding area of ​​the transfer platform assembly is small. If the top area of ​​the transfer platform assembly needs to be expanded at this time, it is only necessary to increase the length of the hydraulic rod through the operation of the hydraulic cylinder to push the guide assembly to unfold and then push the transfer platform assembly to unfold, so that the loading and unloading work of the truck can be completed, so that the area of ​​the top of the transfer platform assembly can be expanded or not according to the actual use situation. In the process of the transfer platform assembly being raised, the area of ​​the transfer platform assembly will continue to expand, which effectively ensures that the range of activities of the personnel on the top of the transfer platform assembly is increased, and ensures the safety of the personnel on the top of the transfer platform assembly.

[0040] The working principle of the present invention is as follows: the equipment is placed in front of the existing docking platform, i.e., the concrete structure table, and ensures that the top of the transfer platform assembly 5 is on the same plane as the concrete table, and can load and unload cargo for trucks of normal height, and can expand the concrete table to a certain extent;

[0041] In the process of loading and unloading cargo on a truck with a higher height, the servo motor 301 is first used to drive the threaded rod 303 to rotate, and then the two push plates 302 are driven to approach each other, and then the two first U-shaped fixing plates 305 are driven to approach the middle so that the rotating rod 306 rotates along the positioning pin 307 to change the angle between the two rotating rods 306, and under the positioning of the sliding bar 309 by the limiting slide rail 3010, the second U-shaped fixing plate 308 and the sliding bar 309 can only translate along the limiting slide rail 3010, so that the plane where the second U-shaped fixing plate 308 and the top of the sliding bar 309 are located rises, and at the same time, the supporting leg assembly 4 will extend with the rise of the transfer platform assembly 5, which can stabilize the rise of the transfer platform assembly 5, and then the transfer platform assembly 5 is raised so that the plane where the transfer platform assembly 5 is located is on the same plane as the bottom of the truck compartment, which is convenient for completing the loading and unloading of cargo on trucks of different heights;

[0042] When the servo motor 301 is working to drive the transfer platform assembly 5 to rise, the second U-shaped fixed plate 308 on one side will push the fourth fixed plate 602 to approach the center of the transfer platform assembly 5, and then when the hydraulic cylinder 606 is not working, that is, the length of the hydraulic rod 607 does not change, the fourth fixed plate 602 approaches the guide assembly 601, which will push the fixed rod 605, the hydraulic cylinder 606, and the hydraulic rod 607 to tilt at an angle, and then rotate under the positioning of the first rotation positioning shaft 604 and the second rotation positioning shaft 608, thereby pushing the second positioning assembly 609 to move to the back side, and then driving the sliding block 6014 to move to the back side, and after moving to the back side of the guide groove of the second guide rail 6012, it will push the second guide rail 6012 and the second limit plate 6013 to move on the inner side of the first guide rail 6011, thereby driving the second fixed platform 5 04. The third fixed plate 505 and the second table 506 move toward the back, thereby expanding the platform on the top of the transfer platform assembly 5 to expand the operating area of ​​the top of the equipment. During the process of expanding the area on the top of the transfer platform assembly 5, the movement of the second fixed base 504 will drive the connecting positioning plate 706 to move toward the back, and then pull the telescopic plate 704 and the fourth limiting plate 705 to move toward the back.

[0043] When the transfer platform assembly 5 does not need to be raised to the highest position, and the distance that the second U-shaped fixing plate 308 pushes the fourth fixing plate 602 to move is short, the unfolded area of ​​the transfer platform assembly 5 is small. If the transfer platform assembly 5 needs to expand the top area at this time, it is only necessary to operate the hydraulic cylinder 606 to increase the length of the hydraulic rod 607 to push the guide assembly 601 to unfold and then push the transfer platform assembly 5 to unfold, so that the loading and unloading work of the truck can be completed, so that the area of ​​the top of the transfer platform assembly 5 can be expanded or not according to actual use. During the process of the transfer platform assembly 5 being raised, the area of ​​the transfer platform assembly 5 will continue to expand, which effectively ensures that the range of activities of the personnel located on the top of the transfer platform assembly 5 is increased, and the safety of the personnel located on the top of the transfer platform assembly 5 is ensured.
