Description

Technical Field

[0001] This utility model belongs to the field of automobile loading technology, and specifically relates to an automobile loading system. Background Technology

[0002] In the process of quantitative loading of bulk materials by truck, the loading port is usually located directly above the loading point of the vehicle. However, the size of the loading port is generally only 500mm-2000mm, which is much smaller than the length of the truck (generally 5-16 meters). Therefore, during the loading process, the loading port needs to be moved relative to the truck to ensure that the material is loaded evenly. Currently, there are two main methods of quantitative loading for trucks: one is quantitative loading based on hopper scales, such as rapid quantitative loading stations for trucks, and the other is quantitative loading based on conventional truck scales.

[0003] The quantitative loading based on hopper scales not only requires pre-loading the target weight of materials into the hopper scale, but also requires close cooperation between the driver and the loader during the loading process, involving multiple moves of the vehicle to ensure even loading of the materials. This significantly limits the improvement of loading efficiency.

[0004] Based on the quantitative loading of conventional truck scales, due to the limited length of the truck scale's load-bearing device, vehicles can only be weighed within a length range of 1-7 meters after being loaded onto the scale. It is impossible to realize the full-process weight detection of the truck as it passes through the loading port from the front, middle and rear sections. Therefore, it is impossible to realize quantitative loading control based on the vehicle's weight throughout the loading process. At the same time, since the loading process also requires the cooperation of the driver and the loading operator, and the vehicle needs to be moved multiple times, it also causes a significant decrease in loading efficiency.

[0005] To overcome the aforementioned shortcomings, flatbed truck scales have emerged in recent years. These scales utilize an oversized platform, such as a 15-18 meter platform, and are constructed by adding wheels to the platform. The flatbed truck scale is then driven by a winch or by the wheels to move back and forth along the rails. During loading, the winch first pulls the flatbed truck to the starting position, where the driver loads the truck onto it. The winch then pulls the flatbed truck towards the destination, loading the truck through the loading port. Once loading is complete and the truck has reached the destination, the driver drives the truck away, and the winch pulls the flatbed truck back to the starting position. This process is repeated for the next truck to be loaded. This method effectively solves the weighing problem during the entire loading process of automobiles and also overcomes the problem of poor driver coordination during loading to some extent. However, since four steps need to be completed each time a car is loaded—namely, the driver driving the car onto the flatbed truck, the flatbed truck moving the car to load the car, the driver driving the car out after loading, and the flatbed truck returning to its starting position—and these four steps are performed sequentially, it also limits the improvement of the overall loading efficiency of automobiles.

The vehicle loading system includes 2N+1 self-driving truck scales, and the loading port is located above the self-driving truck scale in the middle position, where N is a positive integer.

[0011] Preferably, during the loading process of the loading vehicle moving forward to load materials by the self-drive mechanism, there is at least one self-drive weighbridge that is idle behind the loading vehicle.

[0012] Preferably, the self-driving mechanism includes a drive frame and a drive source, sprocket, and chain mounted on the drive frame; the drive frame is disposed on the truck scale, and the drive source drives the chain to rotate through the sprocket to drive the loaded truck located on the chain to move.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Combination Figures 1 to 9 As shown, one embodiment of this utility model provides a vehicle loading system, including five self-driving truck scales 11, 12, 13, 14, and 15. The five self-driving truck scales 11, 12, 13, 14, and 15 have identical structural dimensions, and their length, arranged in sequence, is greater than the length of the loading vehicle 2. Each self-driving truck scale 11, 12, 13, 14, and 15 includes a truck scale 31 and a self-driving mechanism 41 mounted on the corresponding truck scale 31. The five self-driving mechanisms 41 are located on the same horizontal plane and arranged in sequence, enabling the loading vehicle 2 to pass through the five truck scales 31 and under the loading port 3, thereby completing the loading operation.

[0026] In this embodiment, by setting up multiple self-driving truck scales, the self-driving mechanisms on these scales can drive the loading truck to pass under the loading port, creating relative movement between the loading port and the truck to achieve uniform loading of materials. Simultaneously, the weight of the truck can be measured in real time on each scale, accurately controlling the opening and closing of the loading port to achieve quantitative loading. Throughout the process, only the self-driving mechanism on each scale needs to be controlled to drive the truck in one direction and measure its weight in real time to achieve continuous quantitative loading without requiring reciprocating control of the self-driving scales, thus greatly improving the efficiency of quantitative loading.

[0027] Combination Figure 1 As shown, in the vehicle loading system of this embodiment, five self-driving truck scales 11, 12, 13, 14, and 15 are arranged in sequence on the loading platform 5, and the five self-driving mechanisms are basically on the same horizontal plane as the upper surface of the loading platform 5. At the same time, ramps are provided at both ends of the loading platform 5 so that the loaded vehicle 2 can drive towards and away from the self-driving truck scale.

[0028] Combination Figures 1 to 9 As shown, in the vehicle loading system of this embodiment, the total length of the five self-driving truck scales 11, 12, 13, 14, and 15 arranged in sequence is greater than the length of the two loading trucks 2 and 21, and the two loading trucks 2 and 21 can be located on different self-driving truck scales 11, 12, 13, 14, and 15, i.e. Figure 6As shown, when the loaded truck 2, which has completed loading, is on self-driving truck scales 14 and 15, the unloaded truck 21 can simultaneously be on self-driving truck scales 11 and 12. In this embodiment, the loaded truck 2 and the loaded truck 21 have the same structural dimensions.

[0029] At this time, while the self-driving truck scales 14 and 15 are used to weigh the total weight of the loading truck 2 that has completed the loading operation, the self-driving truck scales 11 and 12 can be used to weigh the empty loading truck 21 that has not yet been loaded in parallel. This allows for the weighing of loading trucks in two different processes to be carried out separately, enabling the parallel execution of different processes and further improving the loading efficiency of the truck loading system.

[0030] Combination Figures 1 to 4 As shown, in the vehicle loading system of this embodiment, during the process of the loading vehicle 2 moving forward to load materials by five self-driven mechanisms, that is, moving towards... Figure 3 During the movement to the right as shown, there is at least one idle self-propelled truck scale behind the loaded truck 2, that is, as shown Figure 3 and Figure 4 As shown, during the loading process of the loading truck 2, the loading truck 2 will disengage from the self-driving truck scale 11 behind it, thereby temporarily idling the self-driving truck scale 11.

[0031] During the loading process, when the loading truck is in motion, at least one self-propelled truck scale behind the truck is temporarily idle. This allows subsequent loading trucks to promptly drive onto the idle self-propelled truck scale and enter the loading preparation state. This enables them to be driven onto the self-propelled truck scale for rapid subsequent empty truck weighing and loading operations, reducing waiting time between loading trucks, optimizing the efficiency of inter-process connections, and further improving the loading efficiency of the truck loading system. Specifically, this can be achieved by adjusting the number of self-propelled truck scales and the length relationship between the self-propelled truck scales and the loading trucks.

[0032] Combination Figures 1 to 7 As shown, in the truck loading system of this embodiment, five self-driving truck scales 11, 12, 13, 14, and 15 are set according to the length of the loading truck 2, so that the length of the loading truck corresponds to the length of two self-driving truck scales, and the loading port 3 is located above the self-driving truck scale 13 in the middle position. In this way, three loading trucks can be simultaneously in three different loading processes, namely, empty truck entry, loading, and loaded truck exit, as shown in the figure. Figure 8 The three loading trucks shown are positioned at different stages of the process, thereby greatly improving the utilization rate of multiple self-driving truck scales and increasing the working efficiency of the truck loading system without causing mutual interference between the three stages.

[0033] Of course, in other embodiments, depending on the different operating conditions and circumstances of the truck loading system, such as the different lengths of the trucks and the individual self-driving truck scales, the specific number of self-driving truck scales can be adjusted. For example, if the truck occupies at least N self-driving truck scales (N is a positive integer) during the loading process, the truck loading system can be set to include 2N+1 self-driving truck scales, and the loading port can be placed above the self-driving truck scale in the middle position. In this way, the three trucks can be in three different loading processes without affecting each other.

[0034] Combination Figure 8 and Figure 9 As shown, in the vehicle loading system of this embodiment, the self-drive mechanism 41 includes a drive frame 411 and a drive source 412, a sprocket 413 and a chain 414 mounted on the drive frame 411. The drive frame 411 is disposed on a corresponding truck scale 31. For example, the drive frame 411 is connected to the truck scale 31 by a weighing sensor. The drive source 412 can be composed of a motor and a reducer to drive the chain 414 to rotate through the sprocket 413, thereby driving the loaded vehicle 2 located on the chain 414 to move.

[0035] In this embodiment, by setting the drive source, sprocket, and chain on the drive frame, a modular design of the self-drive mechanism is formed, which facilitates quick disassembly and maintenance of the self-drive mechanism and improves the manufacturing and maintenance efficiency of the vehicle loading system.

[0036] Combination Figure 8 and Figure 9 As shown, in the vehicle loading system of this embodiment, the self-drive mechanism 41 is also provided with a support buckle plate 415, which is detachably connected to the chain 414. In this case, the support buckle plate increases the stability of the connection with the wheels of the loaded vehicle, enabling effective driving of the loaded vehicle. The support buckle plate can be selected with different structures and materials according to the on-site working conditions, for example, a high-friction coefficient rubber material can be selected.

[0037] Combination Figure 9 As shown, in the vehicle loading system of this embodiment, the self-drive mechanism 41 is provided with two sets of parallel and spaced-apart support plates 415, which respectively support the left and right wheels of the loaded vehicle 2. In this way, the length of the drive shaft used to drive the support plates by chain can be reduced, that is, the length of a single drive shaft bearing the weight of the loaded vehicle is reduced, thereby improving the structural strength of the entire self-drive mechanism and ensuring the driving stability of the loaded vehicle.

[0038] In addition, combined Figure 8 and Figure 9As shown, in the vehicle loading system of this embodiment, the self-drive mechanism 41 is further provided with a transition roller 416, and the transition roller 416 is rotatably disposed at both ends of the drive frame 411. By providing a transition roller at each end of the drive frame, the transition roller can be used to realize the transition connection between two adjacent drive frames, enabling the loaded vehicle to smoothly complete the transfer between adjacent self-drive vehicle scales, and ensuring the stability and reliability of the self-drive of the loaded vehicle.

[0039] Furthermore, the vehicle loading system in this embodiment also includes multiple parking space detection units. These units are spaced apart along the five self-driving truck scales to detect the position of the loaded vehicle on multiple self-driving mechanisms. By detecting the position of the loaded vehicle, the system can coordinate with different self-driving truck scales to achieve automated control of weighing, transferring, and loading the vehicle. The parking space detection units can employ a cascaded grating design or a multi-line lidar, etc.

[0040] Combination Figures 1 to 9 As shown, the process of loading a car using the car loading system of this embodiment specifically includes the following steps:

[0041] Step S1: Empty vehicle enters the parking space.

[0042] like Figure 1 As shown, the driver drives the loading truck 2 to the loading platform 5. The position detection unit detects the position of the loading truck 2 and guides the driver to park the front half of the loading truck 2 on the self-driving truck scale 11. After that, the driver can stop operating the loading truck 2 and keep the loading truck 2 in neutral.

[0043] Step S2: Loading the vehicle.

[0044] After completing the empty vehicle placement operation in step S1, control multiple self-driving truck scales to operate, drive the loaded truck to be completely positioned on the self-driving truck scales and pass under the loading port, and use multiple truck scales to measure and weigh the loaded truck throughout the process, thereby controlling the opening and closing of the loading port and completing the quantitative loading of the loaded truck.

[0045] Specifically, firstly, the self-drive mechanism 41 of the self-drive truck scale 11 is activated to drive the loading truck 2 in the following direction. Figure 1 As shown, the vehicle moves to the right. When the loaded vehicle 2 approaches the self-driving truck scale 12, the self-driving mechanism in the self-driving truck scale 12 is activated. Using the self-driving mechanisms in both the self-driving truck scale 11 and the self-driving truck scale 12, the loaded vehicle 2 is moved to... Figure 2At the indicated positions, the loaded truck 2 is moved onto the self-driving truck scales 11 and 12. The operation of the self-driving mechanisms in both scales 11 and 12 is paused, and the truck 2 is statically weighed empty using the scales of both scales. Next, the self-driving mechanisms in scales 11 and 12 are restarted to move the truck 2 forward. Simultaneously, the self-driving truck scales 13, 14, and 15 are controlled to ensure the truck 2 smoothly passes through the loading port 3. During this process, the truck 2 is weighed throughout the loading process using the scales of scales 13, 14, and 15, and the loading volume is controlled in real time to regulate the opening and closing of the loading port 3, thus achieving quantitative and uniform loading of the truck 2.

[0046] Step S3: The loaded vehicle departs.

[0047] Once the loading truck 2 reaches the target loading capacity in step S2, firstly, the loading port 3 is closed to complete the loading operation. Figure 5 The loaded truck 2 is positioned as shown. Then, the self-driving truck scales 13, 14, and 15 perform static weighing on the loaded truck 2, and move the loaded truck 2 forward onto the self-driving truck scales 13 and 14 near the loading platform 5. Figure 6 The driver is then guided to drive the loaded vehicle 2 away from the indicated position, thus completing the loading operation on the loaded vehicle 2.

[0048] Step S4: Repeat steps S1-S3 to allow multiple loading vehicles to complete the loading operation through the vehicle loading system.

[0049] Combination Figures 3 to 6 As shown, in step S2 above, after the loading truck 2 is driven completely away from the self-driving truck scale 11, the next loading truck 21 can be guided to perform the empty truck entry operation in step S1 above. The loading truck 21 is driven to the exit of the self-driving truck scale 11, and while maintaining an effective distance between the loading truck 21 and the loading truck 2, that is, maintaining a distance of one length of the self-driving truck scale to avoid two loading trucks being in the same self-driving truck scale at the same time, the loading truck 21 can be controlled to perform the loading operation in step S2, thereby realizing continuous loading operation and improving loading efficiency.

[0050] In addition, according to Figures 6 to 7As shown, since the two self-driving truck scales in this embodiment can weigh the loaded truck, in step S3, after closing the loading port 3 and stopping the loading, the self-driving truck scales 13, 14, and 15 can continue to move the loaded truck 2 forward. After the loaded truck 2 is moved onto the self-driving truck scales 14 and 15, the movement of the loaded truck 2 is stopped, and the self-driving truck scales 14 and 15 perform static weighing of the loaded truck 2. Then, the driver is directly guided to drive the weighed loaded truck 2 away. This can reduce the need to repeatedly start the self-driving truck scales 13, 14, and 15, and further improve the operating efficiency.
