Detailed Implementation

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0020] Example: As shown in the figure, the loading and unloading equipment for convenient entry and exit from the warehouse according to this utility model includes a trailer body 1. The trailer body 1 includes a platform 2, a towing head 3 located at the front end of the platform 2, rollers 4 that are rotatably connected to the bottom of the platform 2, support feet 5 connected to the front end of the platform 2, and a perimeter fence 6 connected to the perimeter of the platform 2. A receiving mechanism 7 is provided at the rear end of the platform 2, including a hinge frame 8 that is rotatably connected to the rear end of the platform 2. Two parallel unloading plates 9 are connected to the rear end of the hinge frame 8. Rolling wheels 10 are installed in the middle of the bottom surface of the unloading plates 9. The bottom surface of the unloading plate 9 is also connected to an adjustable support leg 11, which is located at the rear end of the rolling wheel 10. The enclosure 6 consists of a front fixed plate 12, side enclosures 13, and a snap-fit ​​tail plate 14. The fixed plate and the enclosures 13 are fixedly connected, and the lower end of the tail plate 14 is rotatably connected to the end of the enclosures 13 and fixedly limited by a pin. A traction mechanism 15 is also provided on the front fixed plate 12, and a sliding mechanism 16 is symmetrically provided on the inner side of the enclosures 13. The traction mechanism 15 drives the sliding mechanism 16 to move within the enclosures 13. A fixing frame 33 is also connected to the front fixed plate 12. The fixing frame 33 is a ring 30 structure used to connect to the external vehicle head at the front end of the vehicle plate 2.

[0021] refer to Figure 1-2 In this embodiment, the bottom of the trailer body 2 is supported by rollers 4, and the front traction head 3 is detachably connected to the trailer head. The trailer body 1 is moved by the active traction of the trailer head. When moving, the support legs 5 are retracted, and when positioning, the support legs 5 are lowered so that the support legs 5 and rollers 4 form a support. At this time, the trailer head can be detached to move other trailer bodies 1. The trailer body 1 is loaded and unloaded with the assistance of the enclosure 6. Specifically, the tailgate 14 at the rear is pulled upward with the pin so that the upper part of the tailgate 14 contacts the end of the enclosure 13 for limiting and removing the tailgate 14. At this time, the tailgate 14 is then removed. The receiving mechanism 7 at one end is connected to the platform 2 without obstruction. Under the pull of the traction mechanism 15, the goods move onto the platform 2 through the receiving mechanism 7. At the same time, the sliding mechanism 16 is used to intercept the goods laterally, distributing the pulling force of the goods into the sliding mechanism 16. There is no need to add a hook 20 or a rope to the goods, which improves loading and unloading efficiency. Conversely, when unloading from the platform 2, the goods are tilted outward by the lifting of the platform 2. At this time, the traction mechanism 15 assists in slowly releasing the sliding mechanism 16, so that the goods can slowly slide towards the receiving mechanism 7 by gravity and traction force and be placed on the ground. When the carriage is high, the unloading plate 9 is raised using adjustable outriggers and hydraulic outriggers, so that the rollers 10 are suspended in the air. The tail of the unloading plate 9 is then attached to the carriage, connecting the carriage to the platform 2, which facilitates the movement of goods onto the platform 2. After the transfer is completed, the unloading plate 9 is lowered and the adjustable outriggers are retracted, so that the rollers 10 are supported on the ground. When moving, the rollers 10 follow the movement to transfer the goods into the warehouse. Conversely, goods that are high up in the warehouse can be loaded onto the truck and transferred to the transport carriage for movement, reducing intermediate transfer links and improving loading and unloading efficiency.

[0022] The traction mechanism 15 includes a winch 17, a reel 18, a wire rope 19, and a hook 20. Two winches 17 are symmetrically installed at the front end of the front fixed plate 12. The reel 18 is connected to the output shaft at the front end of the winch 17. The front fixed plate 12 is also provided with a traction ring 21 to guide the wire rope 19. The wire rope 19 passes through the traction ring 21 and is connected to the hook 20, with the other end connected to the reel 18. The traction ring 21 has a circular ring 30 at the head and a threaded rod 31 at the tail. A fastening nut 32 is connected to the threaded rod 31, and a bearing that is rolled and connected to the wire rope 19 is installed inside the circular ring 30.

[0023] refer to Figure 3 In this embodiment, the winch 17 drives the reel 18 to rotate via an external drive, causing the wire rope 19 to wind, tighten, or release on the reel 18. The wire rope 19 passes through the fixed plate via the traction ring 21 and is guided to extend into the vehicle platform 2, so that the hook 20 is detachably connected to the sliding mechanism 16 inside the vehicle platform 2, which can pull the sliding connection to move back and forth along the vehicle platform 2. The bearing installed in the traction ring 21 can guide the movement direction of the wire rope 19, reduce mechanical wear and improve service life. The power mechanism is simple, and it can not only pull the goods onto the vehicle platform 2, but also drag the goods to slowly slide down to complete the unloading when the vehicle platform 2 is tilted for unloading.

[0024] The sliding mechanism 16 includes mounting grooves 22 formed on the inner walls of the side panels 13, a set of central rollers 23 that are rotatably connected to the mounting grooves 22, a central shaft 24 rotatably connected at the center of the central rollers 23, a connecting rod 25 installed between every two central shafts 24, a snap-fit ​​groove 26 provided at the upper middle part of the connecting rod 25, a stop rod 27 vertically inserted between two symmetrical snap-fit ​​grooves 26, a lifting ring 28 installed on the front end face of the stop rod 27, and a traction ring 21 provided on the top surface of the stop rod 27. The head of the lifting ring 28 is a circular ring 30 and the tail is a threaded rod 31, and a fastening nut 32 is connected to the threaded rod 31.

[0025] refer to Figure 4-5In this embodiment, the mounting slots 22 are horizontally opened on both sides of the enclosure 13 and are symmetrically distributed. The center rollers 23 are engaged in the mounting slots 22, so that the center rollers 23 can only slide laterally along the mounting slots 22, that is, close to or away from the tail plate 14, while being longitudinally limited. The center shafts 24, which are rotatably connected to the center rollers 23, are distributed longitudinally. One end of the center shaft 24 is inserted into the center of the center roller 23, and the other end is rotatably connected to the connecting rod 25, so that the two ends of the connecting rod 25 are respectively connected to the two center shafts 24. Each connecting rod 25 has a locking slot 26 for engaging the stop bar 27 in the middle of its upper end. Disassembling the stop bar 27 can facilitate loading and unloading of goods. When it is necessary to move the goods, the lifting ring 28 on the baffle is connected to the traction mechanism 15, so that the stop bar 27 blocks the goods in the middle. When the stop bar 27 is pulled to move towards the front of the vehicle, the goods will be driven to move and complete the loading. Conversely, releasing the traction mechanism 15 can release the goods towards the rear of the vehicle for easy unloading. The traction ring 21 installed on the top of the stop bar 27 can pass the wire rope 19 through the previous stop bar 27 and directly connect to the rear stop bar 27 for driving. If necessary, the stop bar 27 can be directly removed upwards through the snap-fit ​​groove 26 for operation.

[0026] This utility model features a receiving mechanism that uses hydraulic outriggers to raise the unloading plate, suspending the rolling wheels in the air. The rear of the unloading plate is then attached to the truck bed, facilitating the movement of goods onto the truck bed. After completion, the unloading plate is lowered and the adjustable outriggers are retracted, allowing the rolling wheels to support the ground. During movement, the rolling wheels follow the movement, transferring the goods into the warehouse. Conversely, goods at higher locations within the warehouse can be loaded onto the truck bed and moved, reducing intermediate transfer steps and improving loading and unloading efficiency. The structure is simple and easy to use. A traction mechanism is also included, using steel wire ropes and a sliding mechanism to pull the goods, facilitating their movement from the truck bed to the truck bed for handling. Conversely, when unloading into the warehouse, the auxiliary traction of the steel wire ropes pulls the goods, causing them to land slowly and improving safety.
