Description

Technical Field

[0001] This utility model belongs to the field of logistics loading and unloading technology, specifically relating to a new type of auxiliary support for logistics loading and unloading. Background Technology

[0002] In logistics cargo loading and unloading operations, auxiliary supports are key equipment connecting the loading platform and the transport vehicle, and their performance directly affects loading and unloading efficiency and operational safety.

[0003] In the prior art, various structures of loading and unloading auxiliary supports already exist. For example, Chinese utility model patent CN217376594U discloses an auxiliary support for loading and unloading logistics goods. This support mainly includes a support body, a lip plate rotatably mounted on it, and a tongue plate rotatably connected to the end of the lip plate. To drive the tongue plate, this design includes an angle adjustment assembly. This assembly includes a support rod rotatably mounted on the support, the end of which is slidably connected to the lip plate via a slider, and is equipped with a drive assembly to drive the slider's movement. Simultaneously, a linkage assembly enables the tongue plate to move in tandem with the rotation of the lip plate. This mechanical linkage method aims to replace traditional pneumatic or hydraulic cylinder drives, thereby reducing maintenance costs caused by wear of fluid components and extending the service life of the device. However, in practical applications, it has been found that although the angle of the tongue plate is adjusted through the linkage component, the fit between the tongue plate and the floor of the carriage is often difficult to achieve the ideal state after the adjustment process. Due to the differences in carriage height, floor flatness and vehicle parking position, the fixed linkage trajectory may not be able to ensure that the end of the tongue plate always forms a tight and gapless contact with the various carriage floor surfaces. This loose fit will create height differences or gaps, which will not only cause bumps when forklifts, pallet jacks and other equipment pass by, but also affect loading and unloading efficiency.

Detailed Implementation

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-4This utility model provides a novel auxiliary support for logistics loading and unloading, including an L-shaped base frame 1. An adjustable auxiliary frame 2 is rotatably connected to the top of the L-shaped base frame 1. A reinforcing plate 101 is fixedly connected to the right angle of the L-shaped base frame 1. Multiple auxiliary rollers 3 are rotatably connected inside the adjustable auxiliary frame 2. A fitting plate 4 that overlaps with the loading and unloading cart is rotatably connected to the other end of the adjustable auxiliary frame 2. An adjusting component for adjusting the angle of the adjustable auxiliary frame 2 is provided inside the L-shaped base frame 1. The adjusting component includes a first inclined support rod 6 rotatably connected to the bottom of the auxiliary rollers 3. A threaded block 601 is rotatably connected to the bottom end of the first inclined support rod 6. A second forward and reverse motor 7 is fixedly connected to one end of the L-shaped base frame 1. A second conveying screw 701 is fixedly connected to the output shaft of the second forward and reverse motor 7. The threaded block 601 is slidably connected inside the L-shaped base frame 1 and threadedly connected to the outside of the second conveying screw 701. The L-shaped base frame 1 serves as the basic support for the entire frame. A reinforcing plate 101 is fixedly connected at its right angle to significantly enhance the structural strength and overall stability. The adjustment auxiliary frame 2 is installed on the top of the L-shaped base frame 1 by a rotating connection. Multiple auxiliary rollers 3 are rotatably connected inside to provide rolling friction during loading and unloading of goods and reduce handling resistance. The end of the adjustment auxiliary frame 2 away from the L-shaped base frame 1 is rotatably connected to a bonding plate 4, the core function of which is to overlap with the interior of the truck bed to form a smooth transition bridge. When the second forward and reverse motor 7 is started to drive the second conveying screw 701 to rotate forward and reverse, the threaded block 601 can be driven to move linearly back and forth along the L-shaped base frame 1. Thus, through the pushing or pulling of the first diagonal brace 6, the entire adjustment auxiliary frame 2 is raised or lowered around its hinge point with the L-shaped base frame 1, completing the initial angle adjustment.

[0018] Please see Figures 1-3 The bottom of the bonding plate 4 is provided with an auxiliary component for adjusting the fit with the vehicle body. The bonding plate 4 has a triangular cross-section and a slot is opened inside the bonding plate 4. Multiple triangular support plates 401 for reinforcement are fixedly connected at equal intervals inside the slot. A right angle plate 402 is fixedly connected to the bottom of the bonding plate 4. One side of the right angle plate 402 overlaps with the bottom of the bonding plate 4 and the vehicle body. The auxiliary component includes a first positive and negative motor 5 fixedly connected to the bottom of the adjustment auxiliary frame 2. A first conveying screw 501 is fixedly connected to the output shaft of the first positive and negative motor 5. A transmission plate 502 is threadedly connected to the outside of the first conveying screw 501. Moving blocks 503 are fixedly connected to both ends of the transmission plate 502. Guide columns 504 are fixedly connected to both sides of the bottom of the adjustment auxiliary frame 2. Two moving blocks 503 are slidably connected to the outside of the two guide columns 504 respectively. A connecting arm 505 is rotatably connected to the bottom of each moving block 503. The other end of each connecting arm 505 is rotatably connected to one side of the right angle plate 402. When the first forward and reverse motor 5 starts and drives the transmission plate 502 to move back and forth along the guide column 504, the right-angle plate 402 can be pushed or pulled by the connecting arm 505, so that the bonding plate 4 can rotate slightly around its hinge point with the adjustment auxiliary frame 2, thereby achieving precise adjustment of the end height and ensuring seamless bonding with the carriage floor. By adopting a triangular structure and a built-in triangular plate support plate 401, the bonding plate 4 greatly enhances its bending and impact resistance while ensuring the structure is lightweight.

[0019] Please see Figures 1-4 The bottom of both sides of the adjustment auxiliary frame 2 is rotatably connected with a second diagonal brace 8. The top of the L-shaped base frame 1 is fixedly connected with a side frame 9 on both sides. The bottom end of the second diagonal brace 8 is rotatably connected with a side column 801 on the side facing the side frame 9. The side frame 9 has a sliding groove 901 for sliding the side column 801 inside. Multiple inclined self-locking grooves 902 are equidistantly opened at the bottom of the sliding groove 901. When the angle of the auxiliary frame 2 is adjusted, the side column 801 moves in the slide groove 901. When it is adjusted to the appropriate position, the side column 801 will slide into the corresponding self-locking groove 902 under the action of gravity and load component. The inclined design of the self-locking groove 902 can effectively lock the reverse movement of the side column 801, forming a reliable mechanical self-lock, and preventing the support from accidentally shifting or shaking under heavy load.

[0020] The working principle and usage process of this utility model are as follows: First, the L-shaped base frame 1 serves as the support for the bracket. A reinforcing plate 101 is provided at the right angle to enhance the structural strength and stability. An adjustable auxiliary frame 2 is rotatably connected to the top of the L-shaped base frame 1 and has multiple auxiliary rollers 3 built in to reduce handling resistance. A bonding plate 4 is provided at its end to form a smooth transition with the truck bed. The second forward and reverse motor 7 is started to drive the second conveying screw 701 to rotate in both directions, which drives the threaded block 601 to move linearly along the L-shaped base frame 1. The first diagonal brace 6 pushes / pulls the adjustment auxiliary frame 2 to lift / lower around the hinge point to complete the initial angle adjustment. The first forward and reverse motor 5 is started to drive the transmission plate 502 to move along the guide column 504. The right angle plate 402 is pushed / pulled by the connecting arm 505, so that the bonding plate 4 rotates slightly around the hinge point to achieve precise adjustment of the end height and ensure seamless bonding with the car floor. The bonding plate 4 adopts a triangular structure and has a built-in triangular plate support plate 401, which takes into account both lightweight and bending resistance and impact resistance. When adjusting the angle of the auxiliary frame 2, the side column 801 moves in the slide groove 901; after it is in place, the side column 801 slides into the self-locking inclined groove 902. The inclined design forms a reliable mechanical self-lock to prevent accidental back-movement or shaking under heavy load.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
