[0022] This utility model embodiment provides a semi-automatic loading and unloading device, such as... Figure 1-5 As shown, the semi-automatic loading and unloading device includes: a base 1, on which a placement rack 101 is provided; a connecting seat 2 mounted on the placement rack 101, the bottom of the connecting seat 2 contacting the top of the placement rack 101; an item placement platform 3 fixedly installed on the connecting seat 2 for placing items; an adjustment mechanism provided on the base 1 and the placement rack 101 for adjusting the height of the item placement platform 3; and a disassembly mechanism provided on the connecting seat 2 and the placement rack 101 for disassembling the connecting seat 2.

[0023] In this embodiment, when loading and unloading items, if it is necessary to unload items into the corresponding compartment, the items are placed on the item placement platform 3. The entire device is moved to the side of the compartment door, and the adjustment mechanism is activated to move the items on the item placement platform 3 to the corresponding height. At the same time, the worker moves the entire device closer to the vehicle, moving the item placement platform 3 into the interior of the compartment and into contact with the bottom inner wall of the compartment. Then, the disassembly mechanism is operated to disconnect the connecting seat 2 from the placement rack 101. The worker can then push the connecting seat 2 to push the items on the item placement platform 3 directly into the compartment. In this way, the worker can conveniently unload the items in the item placement platform 3 into the compartment without the need for manual labor. The device allows staff to move items back and forth, reducing their workload and providing convenience. At the carriage door, loading and unloading can be done directly according to actual needs. After unloading, the item placement platform 3 is fixed back onto the placement rack 101. Then, the staff can move the entire device away. Similarly, when unloading items inside the carriage, the same method can be used. This device facilitates loading and unloading for staff, allowing them to directly move the item placement platform 3 into the carriage for loading and unloading, eliminating the need for staff to constantly move items back and forth within the carriage, thus reducing their workload and providing convenience.

[0024] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a mounting bracket 4 fixedly mounted on the base 1, a motor 5 fixedly mounted on the mounting bracket 4; a lead screw 6 rotatably mounted on the mounting bracket 4, one end of the lead screw 6 being fixedly connected to the output shaft of the motor 5; and a connecting block 7 threaded onto the lead screw 6, the connecting block 7 being fixedly connected to the placement bracket 101.

[0025] In this embodiment, when using the adjustment mechanism, the motor 5 is started, which drives the lead screw 6 to rotate. With the cooperation of the limit rod 19 and the limit frame 20, the placement rack 101 can be limited, so that the lead screw 6 can stably drive the connecting block 7 to move, thereby driving the connecting seat 2 on the placement rack 101 to move up and down. This allows the height of the items on the item placement platform 3 to be adjusted, making it easier to load and unload the items.

[0026] In a further preferred embodiment of the present invention, connecting frames 8 are symmetrically fixedly installed on both sides of the connecting seat 2, and the connecting frames 8 are provided with moving wheels 9 for moving the connecting seat 2.

[0027] In this embodiment, the movable wheel 9 facilitates the movement of the connecting seat 2 by the staff.

[0028] In a further preferred embodiment of the present invention, the disassembly mechanism includes: a frame 10 fixedly installed on the placement rack 101; a telescopic rod 11 fixedly installed on the frame 10, with a positioning block 12 fixedly installed on the output shaft of the telescopic rod 11; and a positioning groove 13 formed on the placement rack 101, wherein the positioning groove 13 and the positioning block 12 are adapted to each other.

[0029] In this embodiment, when using the disassembly mechanism, the telescopic rod 11 is activated to move the positioning block 12, causing the positioning block 12 to disengage from the connecting frame 8 and the positioning groove 13. This allows the workers to disconnect the connecting seat 2 from the placement rack 101, and the item placement platform 3 can be moved directly into the carriage for loading and unloading operations. This eliminates the need for workers to constantly move items back and forth in the carriage, reducing their workload and providing them with convenience.

[0030] In a further preferred embodiment of the present invention, a limiting plate 14 is fixedly installed on the placement rack 101, and a slot 16 is provided on the limiting plate 14. A locking block 15 is fixedly installed on the connecting seat 2, and the locking block 15 and the slot 16 are adapted to each other.

[0031] In this embodiment, when the worker fixes the connecting seat 2 on the placement rack 101, the locking block 15 and the locking groove 16 on the connecting seat 2 are connected accordingly. Then, the telescopic rod 11 is activated to drive the positioning block 12 to move, so that the positioning block 12 passes through the connecting rack 8 and connects with the positioning groove 13, thereby fixing the connecting seat 2 on the placement rack 101.

[0032] In a further preferred embodiment of the present invention, two side plates 17 are symmetrically fixedly installed at the bottom of the item placement platform 3, and multiple auxiliary wheels 18 are rotatably installed on both side plates 17.

[0033] In this embodiment, the side plate 17 and the auxiliary wheel 18 cooperate with each other to facilitate the movement of the item placement platform 3 by the connecting seat 2.

[0034] In a further preferred embodiment of the present invention, a limiting rod 19 is fixedly installed on the mounting frame 4, and a limiting frame 20 is fixedly installed on the placement frame 101. The limiting frame 20 and the limiting rod 19 are slidably connected.

[0035] In this embodiment, the limiting rod 19 and the limiting frame 20 work together to limit the placement frame 101, thereby allowing the lead screw 6 to stably drive the connecting block 7 and the placement frame 101 to move, and thus adjust the height of the items on the item placement platform 3.

[0036] In summary, compared with related technologies, the entire device facilitates the loading and unloading of items by staff, and allows items to be placed directly on platform 3 and moved into the carriage for loading and unloading. This eliminates the need for staff to constantly move items back and forth within the carriage, reducing their workload and providing them with greater convenience.
