Description

Technical Field

[0001] The utility model relates to the technical field of road freight transportation, in particular to a fast freight loading and unloading mechanism for road freight transportation. Background Art

[0002] In the modern logistics industry, with the continuous advancement of science and technology, intelligence and automation have become the key forces driving the development of the industry. The efficient operation of the logistics industry plays a vital role in ensuring the order of social production and life. However, in the logistics chain, especially in large-scale transfer yards, the transmission of goods in the last section between logistics vehicles and goods has always been a difficult problem that is difficult to accurately control. The efficiency of this link directly affects the fluency and timeliness of the entire logistics system.

[0003] The background of cargo handling organizations can be traced back to the logistics industry's constant pursuit of efficiency and accuracy. With the growing global trade, higher requirements have been placed on the logistics industry. Traditional cargo loading and unloading methods can no longer meet the needs of speed, safety and efficiency. These organizations use advanced mechanical structures and control systems, which can complete large amounts of cargo loading and unloading operations in a short period of time, and can adapt to various complex environments and climatic conditions.

[0004] On the technical level, the rapid cargo loading and unloading mechanism adopts a variety of innovative technologies, including highly automated control systems, high-precision robotic arms, and intelligent material handling technology.

[0005] In addition, fast cargo loading and unloading mechanisms have good scalability and flexibility, and can be customized according to different logistics needs. They can be integrated into existing logistics systems or operate independently to provide fast loading and unloading services for special goods. The widespread application of such mechanisms has not only improved the overall efficiency of the logistics industry, but also injected new vitality into the development of modern logistics industry.

[0006] In short, the rapid cargo loading and unloading mechanisms for road freight transport are typical examples of the application of scientific and technological progress in the logistics industry. Through automated and intelligent technological innovations, they have solved some difficult problems in the traditional logistics loading and unloading process, and provided strong technical support for the efficient operation of modern logistics. With the continuous advancement and application of technology, I believe that the logistics industry will usher in a faster, safer and more efficient loading and unloading era in the future.

[0007] The existing fast cargo loading and unloading mechanism for road cargo transportation is generally aimed at improving the loading and unloading efficiency of the equipment because the cargo cannot slide on the loading and unloading frame when the traditional loading and unloading frame is horizontal. For example, the authorized Chinese patent CN115848889A discloses a fast cargo loading and unloading device for road cargo transportation, which can be equipped with a support frame, a reinforcement plate, a support column, a limit plate, a loading and unloading frame, a driving motor, a driving shaft, a pulley, a transmission belt, a push plate, a roller drum, a fixing rod, an auxiliary roller, an adjustment mechanism, The supporting plate, U-shaped support plate, positioning ring, snap ring, wire rope, fixed support block, reel plate, reinforcement mechanism, coaxial gear plate, conveyor belt, transmission gear, fixed box, cylindrical rod, crank connecting rod, movable pull rod, guide piston, hollow tube, positioning suction cup, protection mechanism, guide slide plate, limit shaft rod, rectangular block, telescopic rod, hollow tube, inclined plate and positioning shaft rod and other structures are used together to realize automatic lifting and angle adjustment of the loading and unloading rack, and enhance stability by changing the pressure, thereby effectively improving the automation and safety of cargo loading and unloading.

[0008] However, when the cargo loading and unloading mechanisms of road freight transport in the above-mentioned cited documents are used, especially in the control of the transmission of items in the last distance between logistics vehicles and goods in large transfer yards, due to the wide variety of vehicles involved in the logistics industry, from small trucks to large container trucks, the height of the loading plate of each vehicle is different. This difference directly leads to the design limitations of the loading and unloading mechanism, making it impossible for the cargo loading and unloading mechanism to adapt to all types of vehicles, and thus unable to achieve precise control of height and position, which not only increases the efficiency and quality of loading and unloading operations, but may also cause damage to the goods during the loading and unloading process, thereby increasing logistics costs.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 3 , the utility model provides a technical solution: a fast cargo loading and unloading mechanism for road cargo transportation, comprising a cargo loading and unloading mechanism body 1, a lifting and adjusting mechanism 200 is installed on one side of the cargo loading and unloading mechanism body 1;

[0032] By using the lifting and adjusting mechanisms 200 on the cargo loading and unloading mechanism body 1 in coordination with each other, it is possible to quickly adjust the height of the actual loading plate of different vehicles, thereby ensuring the high accuracy and consistency of the loading or unloading process, ensuring the stability and safety of the cargo during loading and unloading, reducing the risk of cargo damage due to height mismatch, reducing manual intervention, speeding up operations, and reducing the error rate, which not only improves the efficiency of loading and unloading operations, but also allows multiple batches of cargo to be processed in the same time.

[0033] In this embodiment, the lifting adjustment mechanism 200 is a structure for quickly adjusting the actual height of the loading board according to different vehicles.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting and lowering adjustment mechanism 200 includes a mounting base plate 201 placed parallel to the ground and two hollow rectangular blocks 202 respectively fixedly mounted on one side of the mounting base plate 201 away from the ground and in mirror symmetry, and a connecting bracket 203 and a driving force component mounted on the connecting bracket 203 are fixedly mounted between opposite sides of the two hollow rectangular blocks 202 by bolts;

[0035] A rotation groove 205 is provided on the inner side of the hollow rectangular block 202;

[0036] The lifting and adjusting mechanism 200 also includes a gear transmission assembly connected to one side of the driving force assembly and connected to the inner wall of the rotating groove 205, the gear transmission assembly is connected to a spur gear 207 and a lifting and pushing assembly connected to the spur gear 207 and located in the hollow rectangular block 202, and a fixed plate 210 is connected between the two lifting and pushing assemblies on the side away from the ground.

[0037] It should be noted that the driving force assembly includes a dual-axis servo motor 2041, a rotating rod 2042 and a bearing support 2043; one side of the dual-axis servo motor 2041 is fixedly mounted on one side of the connecting bracket 203, one end of the rotating rod 2042 is fixedly connected to the output shaft of the dual-axis servo motor 2041, and the other end thereof passes through the bearing support 2043 and the hollow rectangular block 202 in sequence and extends into the rotating groove 205 to be connected to the gear transmission assembly, so as to be able to stably drive the gear transmission assembly to rotate.

[0038] It can be understood that one side of the bearing support 2043 is fixedly connected to one side of the connecting bracket 203, and the two bearing supports 2043 are distributed in mirror symmetry, and the outer side of the rotating rod 2042 is rotatably connected to the inner side of the bearing support 2043 through a bearing in order to stably support the rotating rod 2042 for rotation.

[0039] In addition, the gear transmission assembly includes a driving bevel gear 2061, a follower bevel gear 2062 and a connecting rod 2063; one side of the driving bevel gear 2061 is fixedly connected to an end of the rotating rod 2042 away from the dual-axis servo motor 2041, the driving bevel gear 2061 and the follower bevel gear 2062 are meshed with each other, and the two ends of the connecting rod 2063 are respectively rotatably connected to the inner wall of the rotating groove 205 through bearings, and the outer side of the connecting rod 2063 is fixedly connected to the inner side of the follower bevel gear 2062, so that when the driving bevel gear 2061 rotates, it can drive the connecting rod 2063 to rotate by driving the meshed follower bevel gear 2062 thereon to drive the rotation, thereby driving the spur gear 207 to rotate stably in situ.

[0040] In this embodiment, the lifting and pushing assembly includes a tooth plate 2081, a support plate 2082 and a support rod 2083; one side of the tooth plate 2081 is meshed with the outer side of the spur gear 207, the side of the support plate 2082 close to the hollow rectangular block 202 is fixedly connected to one side of the tooth plate 2081, and the side of the support plate 2082 away from the ground is fixedly installed with two support rods 2083 in mirror symmetry;

[0041] The two tooth plates 2081 and the four support rods 2083 are fixedly connected to one side of the fixed plate 210 at the side away from the ground, so as to stably push the cargo loading and unloading mechanism body 1 to be quickly adjusted according to the actual loading plate height of the truck.

[0042] It should also be noted that the two opposite sides of the two hollow rectangular blocks 202 are provided with moving holes 209 for the support plate 2082 to slide against, so as to ensure the stable movement of the support plate 2082.

[0043] It should be further explained that the hollow rectangular block 202 is a rectangular structure with openings on the upper and lower end faces. The outer side of the spur gear 207 extends to the outside of the rotating groove 205 and meshes with the tooth plate 2081. This is to enable the tooth plate 2081 to be lifted and lowered in the hollow rectangular block 202 when the spur gear 207 rotates, and to push the fixed plate 210 to lift and lower, thereby adjusting the height position of the cargo loading and unloading mechanism body 1.

[0044] The working principle of the above embodiment is:

[0045] When adjusting according to the actual loading plate height of the truck, first start the dual-axis servo motor 2041, and drive the rotating rod 2042 to rotate stably under the rotation support of the bearing, and drive the follower bevel gear 2062 engaged on the active bevel gear 2061 to rotate, so as to drive the connecting rod 2063 to rotate stably in situ under the rotation support of the bearing, and the spur gear 207 rotates accordingly. Since the tooth plate 2081 can only move in the hollow rectangular block 202 under the sliding connection between the support plate 2082 and the movable hole 209, the tooth plate 2081 is stably lifted and lowered on the inner side of the hollow rectangular block 202 under the action of the meshing thrust on one side, and the support rod 2083 moves synchronously therewith, thereby pushing the fixed plate 210 to move, and the height of the cargo loading and unloading mechanism body 1 can be adjusted.

[0046] Compared with the prior art: the rapid cargo loading and unloading mechanism for road cargo transportation can be quickly adjusted according to the actual loading plate height of different vehicles through the mutual cooperation between the lifting and adjusting mechanisms 200 on the cargo loading and unloading mechanism body 1, so as to ensure the high accuracy and consistency of the loading or unloading process, ensure the stability and safety of the cargo during the loading and unloading process, reduce the risk of cargo damage caused by height mismatch, reduce manual intervention, speed up the operation, and reduce the error rate. It not only improves the efficiency of loading and unloading operations, but also can process multiple batches of cargo in the same time, solving the problem that the existing loading and unloading mechanism cannot adapt to all types of vehicles and cannot achieve precise control of height and position.

[0047] The electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing publicly available power connection technology and power supply are also common knowledge in the field, so this application will not go into details.

[0048] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0049] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
