Abstract
Description
Technical Field
[0001] This utility model belongs to the field of track scale loading technology, and specifically relates to a relay-type array short track scale assembly device. Background Technology
[0002] As one of the main modes of transport for the three major bulk materials (coal, iron ore, and grain), railways play an important role in the quantitative loading of bulk materials based on rail scales.
[0003] Currently, bulk material loading based on rail scales mostly involves blind loading or pre-loading with markings before the entire wagon enters the scale's load-bearing range. Weight checks and final loading are then performed once the wagon enters the scale. However, because rail scales are typically 13-14 meters long, while wagons are 12-14 meters long, the distance between the front wheels and the exit point of the wagon after it enters the scale is very short, making it easy for the wagon to exit. Furthermore, the distance between the next wagon and the scale is also very short, making it easy for the wagon to enter the scale. This results in an extremely short window for the scale to check the weight of the wagon. In this case, weight checks and final loading can only be completed by stopping the wagon after it enters the scale. This greatly affects the loading speed and makes it impossible to control the distribution of materials, easily leading to uneven loading.
[0004] In addition, rapid quantitative loading stations based on large hopper scales above the railway can improve loading efficiency, but they are tall, large in size, and expensive. They can only weigh the net weight of the loaded materials and cannot weigh the total weight of the loaded cars based on the actual tare weight of each car. The total weight of the loaded cars is an important indicator for detecting the loading results of the cars. At the same time, this loading method cannot detect the uneven loading of materials into the cars. As a result, disputes and penalties often arise in the actual loading process due to overloading or uneven loading of the total weight of the loaded cars. Utility Model Content

[0017] The advantages and beneficial effects of this utility model are as follows: In the relay-type array short track scale group device of this utility model, multiple short track scales are arranged sequentially adjacent to form a short track scale group, which constitutes a metering area that can accommodate two carriages. Furthermore, the length of each short track scale is limited to the wheel spacing between two adjacent carriages, so that each short track scale can only accommodate the front or rear wheel of a single carriage for metering and weighing.

[0020] Figures 2-9 To adopt Figure 1 The diagram shows the process of quantitative loading of a train using a relay-type array short track weighing system. Detailed Implementation
[0021] 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.
[0022] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0023] Combination Figures 1 to 9As shown, one embodiment of this utility model discloses a relay-type array short track scale group device, including ten short track scales 10-19 arranged sequentially adjacent to each other, a wheel position sensor 20, and a control unit. The ten short track scales 10-19 are arranged sequentially adjacent to each other to form a short track scale group, and the minimum total length of their sequential arrangement is 2Lc-L1, where Lc is the length of the carriage and L1 is the width of the loading chute 6. Furthermore, the length of any one of the ten short track scales 10-19 does not exceed the wheel distance between two adjacent carriages, specifically the distance between the rear wheel of carriage 3 and the front wheel of carriage 4, and also the distance between the rear wheel of carriage 4 and the front wheel of carriage 5. The wheel position sensor 20 is arranged along the direction in which the ten short track scales 10-19 are arranged sequentially, and is used to detect the positional relationship between the wheels and the short track scales. The control unit is connected to the wheel position sensor 20 and the ten short track scales 10-19 to obtain the wheel positions and the measurement data of the short track scales where the wheels are located.
[0024] In this embodiment, multiple short rail scales are arranged adjacently to form a short rail scale group, with the minimum total length controlled to 2Lc-L1, where Lc is the length of the wagon and L1 is the width of the loading chute. This allows for weighing of empty wagons before loading and weighing of loaded wagons after loading. Furthermore, the length of each short rail scale is limited to the wheel spacing between two adjacent wagons, ensuring that each short rail scale can only accommodate the front or rear wheels of a single wagon for weighing. During loading, wheel positions can be detected in real time, and the corresponding short rail scale's measurement data can be obtained based on the wheel positions during wagon movement, achieving relay weighing throughout the entire process. Based on the measurement data from different short rail scales, the loading progress, such as the loading amount and off-center loading, can be monitored in real time. This enables one-time measurement of empty wagon tare weight, quantitative loading, total weight of loaded wagons, and off-center loading adjustment, improving loading quality and efficiency.
[0025] In this embodiment of the relay-type array short-rail scale assembly, ten short-rail scales are set according to the length of a single car to weigh the empty car tare weight and the total weight of the loaded car. In this embodiment, the length of each car is equal. If the lengths of the cars are unequal, the minimum total length of the multiple short-rail scales is set based on the lengths of two adjacent cars. Furthermore, when setting multiple short-rail scales, a certain redundant length Lr can be set. In this case, the length of the weighing area of the relay-type array short-rail scale assembly is Lz = 2Lc - L1 + Lr, where the redundant length Lr can be taken as the width of the loading chute L1. Thus, the length of the weighing area of the relay-type array short-rail scale assembly is approximately twice the length of the car. In other embodiments, the length and number of short-rail scales can be adjusted according to design requirements and different usage environments to meet usage requirements.
[0026] Combination Figure 1 As shown, in the relay-type array short track scale assembly device of this embodiment, the short track scales 10-19 all adopt a continuous track, beamless structure, that is, the complete track 21 covering all short track scales is set on the sleepers 23 equipped with weighing sensors 22. In this embodiment, each short track scale corresponds to three sleepers to meet the length requirements of a single short track scale. At the same time, shear force sensors 24 are provided at both ends of each short track scale to cooperate with the weighing sensors 22 to improve the measurement accuracy of the short track scales. The weighing sensors 22 can be rail pad type weighing sensors.
[0027] Thus, when acquiring the measurement data of any short track scale, the corresponding weighing sensor and the shear force sensors at both ends of the short track scale are simultaneously acquired. Based on the data from the weighing sensor and the shear force sensors, the measurement data of the short track scale can be calculated to complete the weighing of the wheels above it. Weighing and measurement without track interruption based on weighing sensors and shear force sensors is existing technology and will not be described further here. In the subsequent description of this embodiment, unless otherwise specified, the measurement data of the short track scale refers to the data obtained based on the corresponding weighing sensor and shear force sensor.
[0028] Of course, in other embodiments, the short-rail scale can also be a broken-rail, beam-type scale, where each short-rail scale has an independent track section, and a box beam is installed below the track, with a load cell installed below the box beam. In this case, the load cell can be a column-type load cell.
[0029] In other embodiments, the short-track scale can also be a continuous track beam type, where the complete track covering all short-track scales is set on a box beam, and load cells are then installed below the box beam. In this case, the load cells can also be column-type load cells, and shear force sensors are installed at both ends of each short-track scale to improve weighing accuracy.
[0030] Combination Figures 2 to 9 As shown, in the relay-type array short track scale group device of this embodiment, the wheel position sensor 20 is a grating sensor. By using a grating sensor, and arranging the grating sensor horizontally at the position corresponding to the wheel height, with the length of the grating sensor being consistent with the total length of the ten short track scales arranged sequentially, the wheel position of the wheel passing through the relay-type array short track scale group device can be detected in real time, thereby accurately identifying the corresponding short track scale.
[0031] Combination Figures 2 to 9 As shown, in this embodiment of the relay-type array short track scale assembly, a vehicle identifier 25 is also provided. The vehicle identifier 25 is located upstream of the relay-type array short track scale assembly, for example... Figure 2 The location of the second short track balance 11 is shown.
[0032] The carriage identifier can identify the carriages entering the relay-type array short-track weighbridge assembly, obtain the carriage data, and then control the loading process. Specifically, the carriage data can be obtained through radio frequency identification (RFID).
[0033] Next, combined Figures 1 to 9 As shown, the operation process of loading trains using the relay-type array short track weighing system of this embodiment is described, and the specific steps are as follows:
[0034] Step S1: Weigh the empty tare weight. Move the car to the relay-type array short track scale assembly. The wheel position sensors detect the position of the wheels in the car. The control unit obtains the corresponding short track scale measurement data based on the wheel position and determines the empty tare weight of the car.
[0035] Specifically, with Figure 2 Taking the shown state as an example, firstly, the carriage 3 is moved to the relay-type array short track scale assembly device, even after the carriage 3 has completely entered the relay-type array short track scale assembly device. Then, the wheel position sensor 20 is used to detect the positions of the front wheels and the rear wheels in the carriage 3. Based on the detected positions of the front wheels and the rear wheels, the control unit obtains the corresponding short track scale measurement data, i.e., as shown. Figure 2The measurement data of the fourth short track scale 13 corresponding to the front wheel and the measurement data of the first short track scale 10 corresponding to the rear wheel are shown. Then, the measurement data of the fourth short track scale 13 and the measurement data of the first short track scale 10 are added together to obtain the empty tare weight of the carriage 3.
[0036] Step S2, loading. The driving car passes through the loading chute. The wheel position sensors detect the wheel position of the car in real time. The control unit obtains the real-time measurement data of the corresponding short track scale based on the wheel position, and controls the loading gate and loading chute to complete the loading operation of the car.
[0037] Specifically, in combination Figures 2 to 7 In the indicated state, the drive carriage 3 moves to the right and passes under the loading chute 6, controlling the loading gate 7 and loading chute 6 to output material to the carriage 3. During this process, the front and rear wheels of the carriage 3 will sequentially pass over different short-rail scales. The wheel position sensor 20 monitors the positions of the front and rear wheels in real time, and the control unit obtains the corresponding short-rail scale measurement data in real time based on the wheel positions, for example, in Figure 4 The measurement data of the first short track scale 10, the second short track scale 11, and the fifth short track scale 14 are obtained at the indicated locations. These three measurement data are then added together to obtain the total weight of the current car body 3, i.e., the weight of the car body plus the current loading weight. For example, in... Figure 6 The measurement data from the sixth short-rail scale 15 and the ninth short-rail scale 18 are obtained at the indicated locations. These two measurement data are then added together to obtain the current total weight of the car body 3, i.e., the weight of the car body and the current loading weight. Based on the real-time measurement data, the opening size of the loading gate 7 is controlled to control the amount of material discharged through the loading chute 6, thus controlling the loading of the car body 3. When the total weight of the car body 3 reaches the loading requirement, i.e., the loading weight meets the requirement, the loading gate 7 is closed to stop further material delivery to the car body 3, thereby completing the loading operation of the car body 3.
[0038] Step S3, Weighing the total weight and off-center load of the vehicle: After loading is completed, the wheel position sensor detects the position of all wheels in the vehicle, the control unit obtains the measurement data of the short rail scales where the wheels are located in different positions in the vehicle, and determines the total weight of the vehicle and the front and rear off-center load weight data based on the measurement data of the different short rail scales and forms a record form.
[0039] Specifically, in combination Figure 7As shown, after completing the loading operation of the carriage 3 and closing the loading gate 7, the wheel position sensor 20 is used to detect the positions of the front and rear wheels in the carriage 3 and obtain the corresponding short track scale measurement data. Specifically, the measurement data of the ninth short track scale 18 and the tenth short track scale 19 where the front wheels are located are obtained to obtain the front bogie weight data Gq, and the measurement data of the sixth short track scale 15 where the rear wheels are located are obtained to obtain the rear bogie weight data Gh. Based on this, the total weight of the carriage 3 G_total = Gq + Gh and the off-center load weight G_off-center = Gq - Gh can be obtained respectively, and recorded to form a loading form. At the same time, the empty tare weight of the carriage 3 obtained before loading can be combined to calculate and record the net weight data of the materials loaded in the carriage 3 for use as subsequent loading detection data.
[0040] Furthermore, in step S2 above, during the process of driving the carriage 3 to move to the right and passing under the loading chute 6 for loading, the control unit obtains the metering data of the short track scale where the front wheels are located and the metering data of the short track scale where the rear wheels are located in real time based on the wheel positions, and then calculates the front and rear off-center load data of the carriage 3 at different times. Figure 5 Taking the shown state as an example, the measurement data of the sixth short track scale 15 and the seventh short track scale 16 corresponding to the front wheels are obtained, and the measurement data of the third short track scale 12 and the fourth short track scale 13 corresponding to the rear wheels are obtained. Based on the difference between the measurement data corresponding to the front wheels and the measurement data corresponding to the rear wheels, the front-to-back deviation data of the current carriage 3 is determined. If the front-to-back deviation data meets the requirements, the subsequent loading operation continues. If the front-to-back deviation data exceeds the required range, that is, when the loading amount at the position corresponding to the front wheels is too high, the loading chute 6 is controlled to move downward and extend into the carriage 3. By using the forward movement of the carriage 3, some of the material in the carriage 3 is pushed to the rear of the carriage, thereby reducing the front-to-back deviation data until the front-to-back deviation data returns to within the required range. Among them, by controlling the size of the loading chute 6 moving downward and extending into the carriage 3, the amount of material pushed can be changed.
[0041] Among these, data such as the total weight of the carriages and the front-to-back deviation of the carriages can be obtained in advance through the carriage recognition device 25. For example... Figure 2 As shown, when the carriage 3 enters the relay array short track scale group device, when it passes the carriage identifier 25 on the second short track scale 11, the carriage identifier 25 can obtain the data of the carriage 3, such as the carriage model and number, and then obtain the corresponding total weight of the carriage, front and rear deviation of the carriage, etc., so as to facilitate subsequent loading control, realize automated acquisition, and improve the automated control effect.
[0042] according to Figures 5 to 9 As shown, when carriage 3 moves forward and passes through loading chute 6 for loading, the next carriage 4 connected to carriage 3 can move synchronously and gradually enter the relay-type array short track scale assembly. When carriage 4 moves to... Figure 8 When the front wheels of carriage 4 are positioned at the fourth short track scale 13 and the fifth short track scale 14, and the rear wheels of carriage 4 are positioned at the first short track scale 10 and the second short track scale 11, the empty tare weight of carriage 4 can be determined using the measurement data from these four short track scales in step S1. Afterwards, carriage 4 is driven forward to begin the loading operation in step S2. Figure 9 As shown.
[0043] By repeating the above operations, the loading process of each carriage can be continuously measured during the train's movement, allowing for real-time control of the loading progress and improving loading quality and efficiency.
[0044] The above description is merely a specific embodiment of this utility model. Under the teachings of this utility model, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this utility model, and the scope of protection of this utility model should be determined by the scope of the claims.
