Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides an adjustable logistics delivery platform, comprising a floor 1, a top plate 2, and a work panel 3, wherein the top plate 2 is located above the floor 1, and the work panel 3 is located above the top plate 2.

[0026] A fixed seat 20 is slidably provided at the upper end of the top plate 2. Two positioning shafts 17 are symmetrically arranged at both ends of the fixed seat 20. Two hydraulic cylinders 10 are symmetrically arranged above the top plate 2. The lower end of the hydraulic cylinder 10 is provided with a positioning seat 19 that is penetrated by the positioning shaft 17 and rotatably connected to the positioning shaft 17. Two limiting seats 12 are symmetrically arranged at the lower end of the working panel 3. The output end of the hydraulic cylinder 10 is provided with a lifting rod 11. The top end of the lifting rod 11 is hinged to the limiting seat 12. A second motor 14 is provided at the upper end of the top plate 2. The output end of the second motor 14 is provided with a second rotating shaft 15. A second screw 16 is provided on the second rotating shaft 15 that penetrates the fixed seat 20 and rotatably connected to the fixed seat 20.

[0027] The tilt angle adjustment mechanism of the work panel 3: This logistics delivery platform relies on a sophisticated and tightly coordinated component system to achieve the tilt angle adjustment of the work panel 3. When the tilt angle of the work panel 3 needs to be adjusted, the second motor 14 is activated. The output end of the second motor 14 drives the second rotating shaft 15 to rotate synchronously, thereby causing the second screw 16 mounted on the second rotating shaft 15 to start rotating. Since the second screw 16 passes through the fixed seat 20 and is rotatably connected to the fixed seat 20, during the rotation of the second screw 16, the fixed seat 20 will move smoothly along the axial direction of the second screw 16 on the surface of the top plate 2.

[0028] Positioning shafts 17 are symmetrically arranged at both ends of the fixed base 20, and the positioning shafts 17 move together with the fixed base 20. The positioning shafts 17 pass through the positioning seat 19 at the bottom of the hydraulic cylinder 10, and the two are rotatably connected. As the fixed base 20 moves, the positioning shafts 17 drive the positioning seat 19 to produce a corresponding displacement, thereby changing the tilt state of the hydraulic cylinder 10. The output end of the hydraulic cylinder 10 is connected to the lifting rod 11, and the top end of the lifting rod 11 is hinged to the limiting seats 12 symmetrically arranged at the bottom of the working panel 3. When the tilt angle of the hydraulic cylinder 10 changes, its output lifting rod 11 will correspondingly lift or lower, ultimately achieving precise adjustment of the tilt angle of the working panel 3.

[0029] In this embodiment, two support rods 18 are symmetrically arranged at the lower end of the top plate 2. The top end of the support rod 18 is hinged to the top plate 2, and the bottom end of the support rod 18 is hinged to the base 4. The upper end of the floor 1 is provided with a first guide rail 5 that passes through the base 4, and the base 4 is slidably connected to the first guide rail 5. The upper end of the floor 1 is provided with a first motor 6. The output end of the first motor 6 is provided with a first rotating shaft 7. Two first screws 8 with reverse thread structure are symmetrically arranged on the first rotating shaft 7, and the two first screws 8 pass through the two bases 4 respectively.

[0030] The overall height adjustment method of the work panel 3: The first motor 6 plays a key role in adjusting the overall height of the work panel 3. After the first motor 6 is started, the first shaft 7 at its output end begins to rotate, and the two first screws 8 with reverse thread structure installed on the first shaft 7 will rotate synchronously. Since the two first screws 8 pass through the two bases 4 respectively, and the bases 4 are slidably connected to the first guide rail 5 set at the upper end of the floor 1, when the first screws 8 rotate, the two bases 4 will move in opposite directions or in opposite directions along the first guide rail 5 according to the transmission principle of the thread.

[0031] The base 4 is connected to the top plate 2 via a hinged support rod 18. This connection method allows the tilt angle of the support rod 18 to change as the base 4 moves. The top end of the support rod 18 is hinged to the top plate 2, and the bottom end is hinged to the base 4. Changes in the tilt angle of the support rod 18 directly raise or lower the top plate 2. Since the work panel 3 is located above the top plate 2, changes in the height of the top plate 2 will inevitably cause a corresponding change in the overall height of the work panel 3.

[0032] In this embodiment, the outer end of the positioning shaft 17 is provided with a movable seat 9 that is slidably connected to the top plate 2, and two second guide rails 13 that pass through the movable seat 9 are symmetrically arranged at the upper end of the top plate 2, and the movable seat 9 is slidably connected to the second guide rails 13.

[0033] In this embodiment, two first guide rails 5 are symmetrically arranged at the upper end of the floor 1, and the cross-sections of the first guide rail 5 and the second guide rail 13 are both T-shaped.

[0034] Stability Enhancement Design Principle: To further improve the stability of the fixed base 20 during movement, a movable base 9 is provided at the outer end of the positioning shaft 17, and two second guide rails 13 are symmetrically installed on the upper end of the top plate 2, passing through the movable base 9. When the fixed base 20 moves, the movable base 9 slides along the second guide rails 13. The second guide rails 13 not only provide precise guidance for the movable base 9, but also effectively limit its movement, thereby greatly enhancing the stability of the fixed base 20 during movement and ensuring that the entire adjustment process can be carried out smoothly and steadily.

[0035] The platform's first guide rail 5 and second guide rail 13 both employ a unique T-shaped cross-section design. This T-shaped cross-section structure offers several significant advantages over ordinary rectangular guide rails. The T-shaped guide rails effectively prevent derailment of the mating base 4 and moving seat 9 during movement and possess stronger load-bearing capacity, better withstanding various stresses during equipment operation. This ensures more reliable connections between components and smoother movement during frequent adjustments, guaranteeing long-term stable operation of the equipment.

[0036] In this embodiment, both the first motor 6 and the second motor 14 are servo motors.

[0037] The platform uses servo motors, specifically the first motor 6 and the second motor 14. Servo motors possess excellent speed and position control capabilities, enabling precise adjustment of the rotation angle and speed of the first screw 8 and the second screw 16. Through precise control of the screw rotation, accurate adjustment of the tilt angle and overall height of the work panel 3 can be achieved, thus meeting the diverse height and angle requirements of different trucks and containers during loading and unloading.

[0038] With its flexible height and angle adjustment, this logistics delivery platform is widely adaptable to various transportation vehicles. Thanks to its excellent work panel with three tilt angles and overall height adjustment capabilities, it can easily handle trucks and containers of various heights and specifications. Whether it's common box trucks, flatbed trucks, various international standard containers, or containers with special transportation needs, the platform can quickly and accurately adjust to the appropriate state, achieving efficient and convenient docking between goods and transportation vehicles. This feature effectively solves the problem faced by traditional fixed-height delivery platforms when adapting to multiple transportation vehicles, significantly improving the efficiency of cargo loading and unloading, and providing strong support for the smooth operation of logistics transportation.

[0039] This logistics delivery platform, through its innovative design, allows for flexible adjustment of its height and angle, greatly reducing reliance on auxiliary equipment such as electric forklifts, effectively lowering labor and material costs, and improving the operational efficiency of logistics companies.

[0040] The platform's precise and flexible adjustment functions allow work panel 3 to quickly adjust to the optimal loading and unloading position within a short time. This efficient adjustment capability reduces waiting time during loading and unloading, optimizes cargo handling routes, and greatly improves cargo loading and unloading efficiency. Real-world application comparisons show that using this shipping platform can significantly shorten the average loading time, helping logistics companies accelerate cargo turnover, improve overall logistics efficiency, and thus gain a competitive edge in the fierce market competition.
