Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle loading, and particularly relates to a vehicle loading system and a loading method. Background Art

[0002] During the process of quantitatively loading bulk materials onto a vehicle, the loading port is usually directly above the vehicle loading point. However, the size of the loading port is generally only 500 mm - 2000 mm, which is much smaller than the length of the vehicle (generally 5 - 16 meters). Therefore, during the loading process, relative movement between the loading port and the vehicle is required to evenly load the materials. Currently, there are mainly two methods for quantitatively loading vehicles. One is quantitative loading based on a hopper scale, such as a rapid quantitative loading station for vehicles, and the other is quantitative loading based on a conventional truck scale.

[0003] For quantitative loading based on a hopper scale, not only is it necessary to pre - configure the materials with a set target weight in the hopper scale, but also during the process of driving the vehicle to the loading point below for loading, close cooperation between the driver and the loader is required, and the vehicle needs to be moved multiple times to evenly load the materials. This greatly limits the improvement of the loading efficiency.

[0004] For quantitative loading based on a conventional truck scale, due to the limited length of the truck scale load - bearing platform, after the vehicle drives onto the scale, weighing can only be carried out within a length range of 1 - 7 meters. It is impossible to achieve full - process weight detection for the vehicle to pass through the loading port in sequence from the front section, middle section, and rear section of the carriage, and thus it is impossible to achieve quantitative loading control based on the vehicle weight throughout the loading process. At the same time, since the driver and the loader also need to cooperate during the loading process and the vehicle needs to be moved multiple times, the loading efficiency is also significantly reduced.

[0005] To overcome the above - mentioned drawbacks, in recent years, a truck scale with a flatbed truck drive form has emerged, that is, an over - sized integral - surface truck scale is used, such as an integral - surface truck scale of 15 - 18 meters. A flatbed truck scale is formed by installing wheels on the integral - surface truck scale, and the flatbed truck scale is driven to reciprocate along the railway by a winch or wheel drive. During the specific loading process, first, the flatbed truck is towed to the starting position by a winch. The driver drives the vehicle onto the flatbed truck, and then the winch towes the flatbed truck in the direction of the end position. During this process, loading is carried out through the loading port. After the loading is completed and the vehicle moves to the end position, the driver drives the vehicle away, and then the winch towes the flatbed truck to move in the reverse direction to reset to the starting position, and the above operations are repeated for the next vehicle loading. This method better solves the weighing problem during the entire vehicle loading process and also overcomes the problem of poor cooperation between the driver to a certain extent. However, since four processes need to be completed each time loading a vehicle, namely the driver drives the vehicle onto the flatbed truck, the flatbed truck moves with the vehicle for loading, the driver drives the vehicle out after loading is completed, and the flatbed truck resets to the starting position, and the four processes are in serial operation, it also limits the improvement of the overall vehicle loading efficiency. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0028] The following will describe in detail the technical solutions provided by each embodiment of the present invention with reference to the drawings.

[0029] Combined with Figures 1 to 9 As shown, an embodiment of the present invention provides an automobile loading system, which includes five self - driving truck scales 11, 12, 13, 14, and 15. The structural dimensions of the five self - driving truck scales 11, 12, 13, 14, and 15 are the same, and the length dimension of the five self - driving truck scales 11, 12, 13, 14, and 15 arranged in series in sequence is greater than the length dimension of the loading vehicle 2. Among them, each self - driving truck scale 11, 12, 13, 14, and 15 includes a truck scale 31 and a self - driving mechanism 41 installed on the corresponding truck scale 31. The five self - driving mechanisms 41 are located on the same horizontal plane and arranged in series in sequence, and can drive the loading vehicle 2 to pass through the five truck scales 31 in sequence and pass under the loading port 3, thereby completing the loading operation.

[0030] In this embodiment, by setting multiple self - driving truck scales, the self - driving mechanisms on the multiple self - driving truck scales can drive the loading vehicle to pass under the loading port, forming a relative movement between the loading port and the loading vehicle to complete the uniform loading of materials. At the same time, the truck scale on each self - driving truck scale can measure the weight of the loading vehicle in real time, so as to accurately control the opening and closing of the loading port and achieve quantitative loading. In the whole process, only by controlling the self - driving mechanism on each self - driving truck scale to drive the loading vehicle unidirectionally and measure the weight of the loading vehicle in real time, the continuous quantitative loading of the loading vehicle can be realized, without the need to control the reciprocating movement of the self - driving truck scale, thus greatly improving the efficiency of quantitative loading of the vehicle.

[0031] Combined with Figure 1As shown, in the vehicle loading system of this embodiment, five self-driving truck scales 11, 12, 13, 14, and 15 are arranged in series on the loading platform 5 in sequence, and the five self-driving mechanisms are substantially on the same horizontal plane as the upper plane of the loading platform 5. At the same time, ramps are respectively provided at both ends of the loading platform 5 so that the loading vehicle 2 can drive onto and off the self-driving truck scale.

[0032] Combined with Figures 1 to 9 As shown, in the vehicle loading system of this embodiment, the total length dimension of the five self-driving truck scales 11, 12, 13, 14, and 15 arranged in series is greater than the length dimensions of two loading vehicles 2 and 21, and the two loading vehicles 2 and 21 can be located on different self-driving truck scales 11, 12, 13, 14, and 15, that is, as Figure 6 shown, when the loaded vehicle 2 that has completed loading is on the self-driving truck scales 14 and 15, the unloaded loading vehicle 21 can be on the self-driving truck scales 11 and 12 at the same time. Among them, in this embodiment, the loading vehicle 2 and the loading vehicle 21 have the same structural dimensions.

[0033] At this time, while using the self-driving truck scales 14 and 15 to weigh the total weight of the loaded vehicle 2 that has completed the loading operation, the empty vehicle weighing of the unloaded loading vehicle 21 can be completed in parallel by means of the self-driving truck scales 11 and 12, so as to perform weighing operations on the loading vehicles in two different processes respectively, realize the parallel progress of different processes, and further improve the loading efficiency of the vehicle loading system.

[0034] Combined with Figures 1 to 4 As shown, in the vehicle loading system of this embodiment, during the process of the loading vehicle 2 moving forward for loading by five self-driving mechanisms, that is, moving in the Figure 3 right direction shown, there is at least one idle self-driving truck scale behind the loading vehicle 2, that is, as Figure 3 and Figure 4 shown, during the loading process of the loading vehicle 2, the loading vehicle 2 will be disengaged from the self-driving truck scale 11 behind it, so that the self-driving truck scale 11 is temporarily in an idle state.

[0035] At this time, when the loading vehicle is in the loading process of moving forward, by making at least one self-driving truck scale behind the loading vehicle in a temporarily idle state, the subsequent loading vehicle can be driven into the idle self-driving truck scale in time to enter the loading preparation state, so as to be quickly driven onto the self-driving truck scale for subsequent empty vehicle weighing operations and loading operations, reduce the connection waiting time between loading vehicles, optimize the connection efficiency between processes, and further improve the loading efficiency of the vehicle loading system. Specifically, the above purpose can be achieved by adjusting the number of self-driving truck scales and the relationship between the length dimensions of the self-driving truck scales and the loading vehicle.

[0036] Combined with Figures 1 to 7 As shown, in the vehicle loading system of this embodiment, five self-driving truck scales 11, 12, 13, 14, and 15 are set based on the length dimension of the loading vehicle 2. Exactly, the length dimension of the loading vehicle corresponds to the length dimensions of two self-driving truck scales, and the loading port 3 is located above the middle self-driving truck scale 13. In this way, three loading vehicles can be in three different processes of loading at the same time, namely, the empty vehicle enters the position, loading, and the heavy vehicle drives out. That is, as Figure 8 shown, the three loading vehicles are respectively in the corresponding positions of different processes, so as to greatly improve the utilization rate of multiple self-driving truck scales and improve the working efficiency in this vehicle loading system without mutual interference and influence among the three processes.

[0037] Of course, in other embodiments, according to the different operating conditions and conditions of this vehicle loading system, such as the different length dimensions of the loading vehicle and the length dimensions of a single self-driving truck scale, the specific number of self-driving truck scales can be adjusted. For example, if at least N self-driving truck scales (N is a positive integer) are occupied during the loading process of the loading vehicle, then this vehicle loading system can be set to include 2N + 1 self-driving truck scales, and the loading port is placed above the middle self-driving truck scale, so as to realize that three loading vehicles are respectively in three different processes of loading without mutual influence among the three processes.

[0038] Combined with Figure 8 and Figure 9 As shown, in the vehicle loading system of this embodiment, the self-driving mechanism 41 includes a driving frame 411 and a driving source 412, a sprocket 413, and a chain 414 installed on the driving frame 411. Among them, the driving frame 411 is set on the corresponding truck scale 31. For example, the driving frame 411 and the truck scale 31 are connected through a weighing sensor, and the driving source 412 can be composed of a motor and a reducer to drive the chain 414 to rotate through the sprocket 413, and then drive the loading vehicle 2 located on the chain 414 to move.

[0039] In this embodiment, by setting the driving source, sprocket, and chain on the driving frame, a modular design of the self-driving mechanism is formed, which is convenient for quickly disassembling, assembling, and maintaining the self-driving mechanism, and improves the manufacturing and maintenance efficiency of this vehicle loading system.

[0040] Combined with Figure 8 and Figure 9As shown, in the vehicle loading system of this embodiment, a support buckle plate 415 is further provided on the self-driving mechanism 41, and the support buckle plate 415 is connected to the chain 414 in a detachable manner. At this time, the use of the support buckle plate can increase the connection stability with the wheels of the loaded vehicle and achieve effective driving of the loaded vehicle. Among them, the support buckle plate can be selected with different structures and materials according to the on-site working conditions, for example, a rubber material with a high coefficient of friction is selected.

[0041] Combined with Figure 9 As shown, in the vehicle loading system of this embodiment, the self-driving mechanism 41 is provided with two groups of support buckle plates 415 that are parallel and spaced apart, and the two groups of support buckle plates 415 respectively carry the left and right wheels of the loaded vehicle 2. In this way, the length of the transmission shaft used to drive the support buckle plate through the chain can be reduced, that is, the length of a single transmission shaft bearing the weight of the loaded vehicle is reduced, the structural strength of the entire self-driving mechanism is improved, and the driving stability of the loaded vehicle is ensured.

[0042] In addition, combined with Figure 8 and Figure 9 As shown, in the vehicle loading system of this embodiment, the self-driving mechanism 41 is further provided with transition rollers 416, and the transition rollers 416 are rotatably arranged at both ends of the driving frame 411. By respectively arranging a transition roller at both ends of the driving frame, the transition connection between adjacent two driving frames can be realized by using the transition roller, so that the loaded vehicle can smoothly complete the transfer between adjacent self-driving vehicle weighbridges, and the stability and reliability of the self-driving of the loaded vehicle are ensured.

[0043] In addition, in the vehicle loading system of this embodiment, a plurality of parking space detection units are further provided. The parking space detection units are arranged at intervals in the manner of being arranged in sequence along five self-driving vehicle weighbridges to detect the position of the loaded vehicle on a plurality of self-driving mechanisms. By detecting the position of the loaded vehicle, the actions of different self-driving vehicle weighbridges can be coordinated to realize the automatic control of weighing, transferring and loading of the loaded vehicle. Among them, the parking space detection unit can adopt a cascaded grating design or a multi-line lidar, etc.

[0044] Combined with Figures 1 to 9 As shown, the process of loading a vehicle using the vehicle loading system of this embodiment specifically includes the following steps:

[0045] Step S1, the empty vehicle enters the position.

[0046] As Figure 1 shown, the driver drives the loaded vehicle 2 to the loading platform 5. With the help of the position detection of the loaded vehicle 2 by the parking space detection unit, the driver is guided to park the front half of the loaded vehicle 2 on the self-driving vehicle weighbridge 11. After that, the driver can suspend the operation of the loaded vehicle 2 and keep the loaded vehicle 2 in neutral gear.

[0047] Step S2, Loading the vehicle.

[0048] After completing the operation of positioning the empty vehicle in Step S1, control multiple self - driving truck scales to work. Drive the loading vehicle to be completely located on the self - driving truck scales and pass under the loading hopper. Weigh the loading vehicle throughout the process through multiple truck scales to control the opening and closing of the loading hopper and complete the quantitative loading of the loading vehicle.

[0049] Specifically, first, control the self - driving mechanism 41 of the self - driving truck scale 11 to act, so as to drive the loading vehicle 2 to move in the Figure 1 right - hand direction as shown. When the loading vehicle 2 approaches the self - driving truck scale 12, control the self - driving mechanism in the self - driving truck scale 12 to act. With the help of the self - driving mechanism in the self - driving truck scale 11 and the self - driving mechanism in the self - driving truck scale 12, move the loading vehicle 2 to the Figure 2 position shown, that is, move the loading vehicle 2 onto the self - driving truck scale 11 and the self - driving truck scale 12. Pause the actions of the self - driving mechanism in the self - driving truck scale 11 and the self - driving mechanism in the self - driving truck scale 12, and use the truck scale of the self - driving truck scale 11 and the truck scale of the self - driving truck scale 12 to weigh the static empty vehicle of the loading vehicle 2. Then, start the self - driving mechanism in the self - driving truck scale 11 and the self - driving mechanism in the self - driving truck scale 12 again, and continue to move the loading vehicle 2 forward. At the same time, cooperate with the control of the self - driving truck scale 13, the self - driving truck scale 14, and the self - driving truck scale 15, so that the loading vehicle 2 smoothly passes through the loading hopper 3. During this process, use the truck scale of the self - driving truck scale 13, the truck scale of the self - driving truck scale 14, and the truck scale of the self - driving truck scale 15 to weigh the loading vehicle during the loading process throughout the whole process, and control the loading amount in real - time to control the opening and closing of the loading hopper 3, and complete the quantitative and uniform loading of the loading vehicle 2.

[0050] Step S3, The loaded vehicle drives out.

[0051] When the loading vehicle 2 being loaded in Step S2 reaches the target loading amount, first, control the loading hopper 3 to close and complete the vehicle - loading operation. For the loading vehicle 2 in the Figure 5 position shown. Then, weigh the static loaded vehicle of the loading vehicle 2 by the truck scale of the self - driving truck scale 13, the truck scale of the self - driving truck scale 14, and the truck scale of the self - driving truck scale 15, and move the loading vehicle 2 forward to the self - driving truck scale 13 and the self - driving truck scale 14 close to the loading platform 5, that is, Figure 6 the position state shown. Then, guide the driver to drive the loading vehicle 2 away and complete the vehicle - loading operation for the loading vehicle 2.

[0052] Step S4, Repeat Steps S1 - S3 to enable multiple loading vehicles to complete the loading operation through this vehicle - loading system in sequence.

[0053] Combined with Figures 3 to 6As shown, in the above step S2, after the loaded vehicle 2 is driven completely away from the self-propelled truck scale 11, the next loaded vehicle 21 can be guided to perform the empty vehicle positioning operation of the above step S1, drive the loaded vehicle 21 to the self-propelled truck scale 11, and while maintaining an effective distance between the loaded vehicle 21 and the loaded vehicle 2, that is, maintaining a distance equal to the length dimension of a self-propelled truck scale and avoiding two loaded vehicles being on the same self-propelled truck scale at the same time, the loaded vehicle 21 can be controlled to perform the loading operation of step S2, thereby realizing continuous loading operation and improving the loading efficiency.

[0054] In addition, according to Figures 6 to 7 As shown, since the two self-propelled truck scales in this embodiment can weigh the loaded vehicle, therefore, in step S3, after closing the loading port 3 to stop loading, the self-propelled truck scales 13, 14 and 15 can also be continuously controlled to move the loaded vehicle 2 forward. After the loaded vehicle 2 is moved onto the self-propelled truck scales 14 and 15, the movement of the loaded vehicle 2 is stopped, and the self-propelled truck scales 14 and 15 weigh the loaded vehicle 2 statically, and then the driver is directly guided to drive the weighed loaded vehicle 2 away. This can reduce the repeated startup of the self-propelled truck scales 13, 14 and 15 and further improve the control efficiency.

[0055] The above is only the specific implementation manner of the present invention. Under the above teaching of the present invention, those skilled in the art can make other improvements or deformations based on the above embodiments. Those skilled in the art should understand that the above specific description is only a better explanation of the purpose of the present invention, and the protection scope of the present invention should be subject to the protection scope of the claims.
