Description

Technical Field

[0001] This utility model relates to the field of transfer platform technology, specifically a slope-adaptive transfer platform. Background Technology

[0002] A transfer platform is a device used for transferring materials or goods. It can transport and move goods. A transfer trolley is a common type of simple transfer platform. Its structure mainly includes a vehicle body, wheels, and handrails. Workers use the transfer trolley to transfer goods.

[0003] However, existing transfer platforms have the following problems during use: when workers push the transfer trolley to transport goods, the vehicle may tilt forward or backward when encountering a steep slope, easily causing goods inside the vehicle to spill out. This is especially problematic for fragile or liquid goods, as there is a lack of means to adjust the platform according to the road slope. Therefore, a corresponding technical solution needs to be designed to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a slope-adaptive transfer platform, which solves the technical problem that when workers push the transfer trolley to transport goods, the vehicle body will tilt forward or backward when encountering a road surface with a large slope, which can easily cause the goods inside the vehicle to fall out. This is especially true for some fragile or liquid goods, as there is a lack of means to adjust according to the road slope.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope-adaptive transfer platform, comprising a frame, handrails, side panels, front wheels, adjustable rear wheels, a slope adjustment component, and a level indicator. The rear of the frame is connected to the inclined handrails. The side panels are divided into four groups and evenly installed on the frame. The front wheels are divided into two groups and symmetrically installed at the front end of the frame.

Each adjustable rear wheel includes a connecting rod, a mounting frame, and a wheel body. The upper end of the connecting rod is connected to the frame, and the lower end is rotatably connected to the mounting frame. The lower end of the mounting frame is connected to the wheel body. The slope adjustment component includes a guide plate with two sets of guide grooves symmetrically opened on its surface and two sets of pressure rods respectively inserted into the two sets of guide grooves. A cross plate is connected between the upper ends of the two sets of pressure rods. A movable connector is installed at the lower end of each pressure rod. The movable connector is installed on the mounting frame. The level indicator is horizontally installed on one side of the side panel.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a slope-adaptive transfer platform, including a frame 1, a handrail 2, a side panel 3, front wheels 4, adjustable rear wheels, a slope adjustment component, and a level indicator. The rear of the frame 1 is connected to the inclined handrail 2. The side panel 3 is divided into four groups and evenly installed on the frame 1. The front wheels 4 are divided into two groups and symmetrically installed at the front end of the frame 1. The adjustable rear wheels are divided into two groups and symmetrically installed at the rear end of the frame 1. The adjustable rear wheels include a connecting rod 5, a mounting bracket 6, and... The upper end of the wheel body 7 and the connecting rod 5 are connected to the frame 1 and the lower end is rotatably connected to the mounting frame 6. The lower end of the mounting frame 6 is connected to the wheel body 7. The slope adjustment component includes a guide plate 9 with two sets of guide grooves 8 symmetrically opened on the surface and two sets of pressure rods 10 respectively inserted in the two sets of guide grooves 8. A cross plate 11 is connected between the upper ends of the two sets of pressure rods 10. A movable connector 12 is installed at the lower end of the pressure rod 10. The movable connector 12 is installed on the mounting frame 6. The level indicator is horizontally installed on one side of the enclosure 3.

[0020] Note: The transfer carts designed in this plan are mainly for transferring and transporting small quantities of goods within a small area.

[0021] Further improvements, such as Figure 1 and 2 As shown, several sets of threaded holes 13 are evenly opened on both sides of the guide plate 9. The inner end of the threaded hole 13 is connected to the guide groove 8. A limit bolt 14 is provided in the internal thread of one set of threaded holes 13. The inner end of the limit bolt 14 abuts against the pressure rod 10. When the inner end of the limit bolt 14 abuts against the pressure rod 10, the pressure rod 10 can be limited.

[0022] Further improvements, such as Figure 3As shown, the movable connector 12 includes a fixed block 16 with an internal movable cavity 15 and a rotating ball 17 movably disposed in the movable cavity 15. The fixed block 16 is fixed on the mounting bracket 6. The movable cavity 15 has a spherical structure. The outer end of the rotating ball 17 is connected to the pressure rod 10, which facilitates the rotation and adjustment of the mounting bracket 6.

[0023] Further improvements, such as Figure 3 As shown, insert rods 18 are fixed on both sides of the rotating ball 17. The outer end of the insert rod 18 is connected to the movable inner cavity 15, which facilitates adaptive rotation adjustment when the pressure rod 10 acts on the mounting frame 6.

[0024] Specifically, the level indicator includes a base plate 19 and a glass tube 20 fixed on the base plate 19. The glass tube 20 is filled with liquid and contains air bubbles. The level indicator has the same structure as the existing level and determines whether the vehicle body is tilted by the position of the air bubbles inside.

[0025] In use: Place the goods to be transported inside the enclosure 3. The staff can push the transfer trolley to transfer the goods by holding the handrail 2. When the transfer trolley encounters a slope while traveling and the level of the frame 1 needs to be adjusted, the staff will check the slope of the level indicator, loosen the limit bolt 14, hold the horizontal plate 11 and adjust the pressure rod 10. The pressure rod 10 acts on the mounting frame 6 to drive the rear wheel body 7 to rotate in the front and rear directions, thereby adjusting the level of the vehicle body and avoiding safety problems of the goods caused by the slope during transportation.
