[0025] In the port coal transportation industry, the car dumper is at the core hub of transportation, supporting railway transportation above and coal storage below. Its operating efficiency and stability are particularly important, directly affecting the stability of the entire port coal transportation process. At present, the positioning detection of the heavy vehicle on the main platform of the car dumper is mainly realized by the photoelectric tube at the input end and the photoelectric tube at the output end, which is easily affected by coal dust, etc. There is a technical problem in the field that the positioning detection stability of the car dumper is poor.

[0026] Hereinafter, the technical solution of the present application will be described in conjunction with specific embodiments.

[0027] Embodiment 1

[0028] Figure 1 Schematic diagram of a tipping machine positioning detection system provided in an embodiment of the present application. Figure 1 As shown, in the technical solution of this embodiment, a tipper positioning detection system is provided, including: a first proximity sensor, used to generate a first proximity signal when the wheel of a car approaches the first proximity sensor; a processor connected to the first proximity sensor, used to receive the first proximity signal; wherein the first sensor is installed at a position corresponding to the wheel of the car close to the exit of the tipper track, and the distance between the first sensor and the tipper track is less than a preset distance.

[0029] The technical problem to be solved by this embodiment is that the existing heavy vehicle positioning detection of the main platform of the tipping machine mainly relies on the input photoelectric tube and the output photoelectric tube, which has poor stability and is restricted by factors such as coal type, coal humidity, and weather. When there is a lot of coal dust in the on-site operation, it will affect the photoelectric tube signal and cause signal loss, resulting in interruption of the automatic operation process and reduced overall operation efficiency; when the photoelectric tube fails, the equipment failure time is increased; when the original photoelectric tube is flipped by the mechanical structure, the detection signal will be blocked and lost, and the flipping action cannot be detected throughout the process. There are technical problems in this field such as insufficient stability, long fault handling time, and limited flipping detection.

[0030] The technical solution of this embodiment is to set a first proximity sensor 100, which is installed at a position corresponding to the wheel 200 of the carriage 500 close to the exit of the dumper track 300, and the distance between the first sensor and the dumper track is less than a preset distance. This embodiment proposes to use a proximity detection switch to detect the wheel to realize the platform heavy vehicle positioning detection.

[0031] The first proximity sensor is, for example, a proximity detection switch, such as an inductive proximity sensor. When a metal wheel approaches, the inductive coil inside the sensor will generate an induced current, thereby triggering a signal output. By installing it at the corresponding position of the wheel near the exit of the tipping machine track, the approach of the wheel can be accurately detected. For example, at the tipping machine operation site at the port, when the carriage moves along the track to a position close to the tipping machine, the first proximity sensor can sense the approach of the wheel in time, thereby providing an accurate signal for subsequent positioning and tipping operations.

[0032] This embodiment effectively solves the problem of existing photoelectric tube detection by installing the first proximity sensor. In actual port coal transportation operations, when there is a lot of coal dust, the photoelectric tube signal is easily affected and lost, resulting in operation interruption and affecting overall efficiency. The first proximity sensor is not affected by the coal dust and can stably detect the wheel position. For example, when the coal dust is diffuse, the photoelectric tube may not work properly, but the first proximity sensor can still accurately detect the wheel proximity signal to ensure the stability of the operation process. At the same time, since the proximity sensor is set on the tipping machine platform and is not affected by the mechanical structure when the tipping machine is flipped, it can continue to detect throughout the flipping action, avoiding the situation where the signal is blocked and lost. During the entire process of the tipping operation, the first proximity sensor can provide real-time wheel position information, providing strong support for safety monitoring. When the position of the carriage is abnormal, an alarm can be issued in time to ensure safe production.

[0033] Embodiment 2

[0034] Figure 2 is a flow chart of a method for detecting a tipping machine positioning provided by an embodiment of the present application, such as Figure 2 As shown, in the technical solution of this embodiment, a tipper positioning detection method based on the above-mentioned tipper positioning detection system is provided, including: obtaining a first proximity signal generated by a first proximity sensor; determining whether the first proximity signal generated by the first proximity sensor is obtained; when the first proximity signal is obtained and the first proximity signal is a preset proximity signal, outputting a tipping signal.

[0035] The technical solution of this embodiment obtains the first proximity signal generated by the first proximity sensor, determines whether the signal is obtained, and outputs a rollover signal when the first proximity signal is obtained and the first proximity signal is a preset proximity signal. The preset signal is, for example, a triangular wave signal of an analog quantity, or a high-level signal of a digital quantity. The signal of the proximity detection switch is used in series as a platform wheel positioning detection point. Obtaining the first proximity signal and making a judgment here is to accurately confirm the position of the wheel. For example, when the first proximity sensor detects that the wheel is approaching, a specific electrical signal is generated, such as a triangular wave signal of an analog quantity, or a high-level signal of a digital quantity. After the system obtains this signal, it is compared with the preset proximity signal. If the signal meets the requirements, it means that the position of the car is accurate and the rollover operation can be performed.

[0036] For example, at the tipping machine operation site, the preset proximity signal can be a specific voltage value or current value. When the signal output by the first proximity sensor reaches this value, the system determines that the car is in place, and can output a tipping signal to start the tipping machine for unloading. This embodiment further improves the accuracy and reliability of the tipping machine positioning detection. By acquiring and judging the first proximity signal, it is possible to avoid erroneous operations caused by misdetection or signal abnormality. For example, in an environment with large coal dust, the photoelectric tube signal is unstable, but this embodiment can ensure that the tipping operation is only performed when the car is actually detected in place through strict judgment of the first proximity signal. Used in series with the photoelectric tube signal, a more accurate positioning detection is formed. When the photoelectric tube is affected by factors such as coal dust and the signal is lost, the first proximity sensor can still provide a stable positioning signal, which reduces the fault handling time and improves the operating efficiency. During the entire tipping operation, the position of the car can be monitored in real time. Once an abnormal situation occurs, such as the displacement of the car position, an alarm can be issued in time to ensure safe production.

[0037] Embodiment 3

[0038] Based on the above embodiment, after the step of determining whether the first proximity signal generated by the first proximity sensor is acquired, the method further includes: outputting a fault alarm signal when the first proximity signal is not acquired within a preset time period.

[0039] The technical solution of this embodiment outputs a fault alarm signal when the first proximity signal is not obtained within a preset time. This embodiment realizes the fault alarm function by monitoring the time of the first proximity signal. For example, a preset time is set, such as 2 seconds. If the system does not receive the signal of the first proximity sensor within this time, it is determined that a fault may have occurred. It may be caused by sensor damage, line failure, or abnormal position of the car. At the tipping machine operation site, when this happens, the system will immediately output a fault alarm signal to remind the staff to deal with it in time. For example, an alarm is sounded through an audible and visual alarm, or a fault prompt message is displayed on the control interface.

[0040] This embodiment adds a fault alarm function to the tipping machine positioning detection system, which improves the reliability and safety of the system. When the photoelectric tube fails, it can be quickly switched through the screen button operation to temporarily shield the photoelectric tube signal. The fault alarm function of this embodiment further improves the reliability and safety of the system, ensuring that problems can be discovered in time and corresponding measures can be taken in any case to ensure the orderly progress of production.

[0041] Embodiment 4

[0042] Based on the above embodiment, the method also includes: obtaining a second proximity signal detected by a second proximity sensor, wherein the second sensor is installed within a preset distance next to the tipping machine track; and monitoring the position of the car based on the first proximity signal and the second proximity signal.

[0043] The technical solution of this embodiment is to obtain a second proximity signal detected by a second proximity sensor, wherein the second sensor is installed within a preset distance next to the tipping machine track; and monitor the position of the car based on the first proximity signal and the second proximity signal. The second proximity sensor is also a proximity detection switch, which is used in conjunction with the first proximity sensor. For example, the second proximity sensor can be installed at a position opposite to the first proximity sensor, or at a position corresponding to other wheels, to improve the accuracy of detection. When the car enters the detection area, the first proximity sensor and the second proximity sensor work simultaneously, detecting the position of the wheel from different angles. For example, at the tipping machine operation site, the first proximity sensor detects the wheel near the tipping machine track exit, and the second proximity sensor detects the part corresponding to the wheel near the track entrance or the part corresponding to other wheels in the car. Through the comprehensive analysis of the two sensor signals, the position information of the car can be more comprehensively grasped.

[0044] This embodiment improves the accuracy and reliability of car position monitoring by adding a second proximity sensor to work together with the first proximity sensor. In actual operation, the two proximity sensors detect wheel signals from different positions respectively, which can more comprehensively grasp the position information of the car. For example, during the operation of the tipping machine, the first proximity sensor and the second proximity sensor work at the same time. When the signals of the two sensors meet the preset conditions, the system can determine that the position of the car is accurate. This can effectively avoid positioning errors caused by misdetection of a single sensor. At the same time, the signals of the two proximity sensors are connected in series with the photoelectric tube signal to form a more accurate positioning detection. When coal dust has a greater impact on the photoelectric tube signal or the photoelectric tube fails, the two proximity sensors can still provide a stable positioning signal, reduce fault handling time, and improve operation efficiency. During the entire process of the tipping operation, the position of the car can be monitored in real time. Once an abnormal situation such as car position offset occurs, an alarm can be issued in time to ensure safe production.

[0045] Embodiment 5

[0046] On the basis of the above embodiment, after the step of monitoring the position of the car body based on the first proximity signal and the second proximity signal, the method also includes: determining whether the position of the car body changes during the tipping process of the tipping machine; when the position of the car body changes during the tipping process of the tipping machine, outputting a displacement alarm signal.

[0047] The technical solution of this embodiment determines whether the position of the car body changes during the tipping process of the tipping machine; when the position of the car body changes during the tipping process of the tipping machine, a displacement alarm signal is output. This embodiment realizes the displacement alarm function by continuously monitoring the position of the car body during the tipping process. For example, when the tipping machine is performing a flipping operation, the system continuously obtains signals from the first proximity sensor and / or the second proximity sensor to determine in real time whether the position of the car body changes. If the position of the car body changes, it may indicate that there is an abnormality in the car press or the car support plate.

[0048] At the car tipping machine operation site, when this situation occurs, the system will immediately output a displacement alarm signal to remind the staff to deal with it in time. For example, an alarm is sounded through an audible and visual alarm, or an alarm message is displayed on the control interface, and the operation of the car tipping machine is stopped at the same time to avoid accidents. This embodiment provides further protection for the safe operation of the car tipping machine in view of the changes in the position of the carriage during the tipping process. For example, in the coal transportation operation at the port, the car tipping machine may cause the position of the carriage to shift due to various reasons during the flipping process, which will not only affect the unloading effect, but also pose a threat to the safety of equipment and personnel. Through the technical solution of this embodiment, abnormal changes in the position of the carriage can be discovered in time, and the staff can quickly take measures to stop the tipping operation, conduct inspections and repairs, avoid accidents, and improve operating efficiency and ensure the orderly progress of production while ensuring safety.

[0049] Embodiment 6

[0050] Based on the above embodiment, the method further includes: acquiring a photoelectric positioning signal detected by a photoelectric sensor; and outputting a rollover signal when the first approach signal and the photoelectric positioning signal indicate that the vehicle compartment is in place.

[0051] The technical solution of this embodiment obtains the photoelectric positioning signal detected by the photoelectric sensor; when the first proximity signal and the photoelectric positioning signal show that the car is in place, a rollover signal is output. This embodiment combines the photoelectric sensor with the first proximity sensor to achieve more accurate positioning detection. For example, when the car enters the detection area, the photoelectric sensor first detects the arrival of the car and generates a photoelectric positioning signal. At the same time, the first proximity sensor is also detecting the position of the wheel. When both signals show that the car is in place, the system outputs a rollover signal.

[0052] At the dumper operation site, this combination can improve the accuracy and reliability of positioning detection. This embodiment combines the photoelectric sensor with the first proximity sensor to improve the accuracy and reliability of positioning detection. In actual operation, the system simultaneously obtains the signals of the photoelectric sensor and the first proximity sensor, and only when both signals show that the car is in place, the dumping signal is output. For example, in the coal transportation operation at the port, the photoelectric sensor and the first proximity sensor cooperate with each other. When the coal dust has a greater impact on the photoelectric sensor signal, the first proximity sensor can still provide a stable positioning signal. This can greatly improve the stability and reliability of the system, reduce fault handling time, and improve operating efficiency.

[0053] Embodiment 7

[0054] Figure 3 is a structural diagram of a tipper positioning detection device provided in an embodiment of the present application, such as Figure 3As shown, in the technical solution of this embodiment, a tipper positioning detection device based on the above-mentioned tipper positioning detection system is provided, including: an acquisition module, used to acquire a first proximity signal generated by a first proximity sensor; a judgment module, used to judge whether the first proximity signal generated by the first proximity sensor is acquired; an output module, used to output a tipping signal when the first proximity signal is acquired and the first proximity signal is a preset proximity signal.

[0055] The technical solution of this embodiment obtains the first proximity signal generated by the first proximity sensor, determines whether the signal is obtained, and outputs a rollover signal when the first proximity signal is obtained and the first proximity signal is a preset proximity signal. The preset signal is, for example, a triangular wave signal of an analog quantity, or a high-level signal of a digital quantity. The signal of the proximity detection switch is used in series as a platform wheel positioning detection point. Obtaining the first proximity signal and making a judgment here is to accurately confirm the position of the wheel. For example, when the first proximity sensor detects that the wheel is approaching, a specific electrical signal is generated, such as a triangular wave signal of an analog quantity, or a high-level signal of a digital quantity. After the system obtains this signal, it is compared with the preset proximity signal. If the signal meets the requirements, it means that the position of the car is accurate and the rollover operation can be performed.

[0056] For example, at the tipping machine operation site, the preset proximity signal can be a specific voltage value or current value. When the signal output by the first proximity sensor reaches this value, the system determines that the car is in place, and can output a tipping signal to start the tipping machine for unloading. This embodiment further improves the accuracy and reliability of the tipping machine positioning detection. By acquiring and judging the first proximity signal, it is possible to avoid erroneous operations caused by misdetection or signal abnormality. For example, in an environment with large coal dust, the photoelectric tube signal is unstable, but this embodiment can ensure that the tipping operation is only performed when the car is actually detected in place through strict judgment of the first proximity signal. Used in series with the photoelectric tube signal, a more accurate positioning detection is formed. When the photoelectric tube is affected by factors such as coal dust and the signal is lost, the first proximity sensor can still provide a stable positioning signal, which reduces the fault handling time and improves the operating efficiency. During the entire tipping operation, the position of the car can be monitored in real time. Once an abnormal situation occurs, such as the displacement of the car position, an alarm can be issued in time to ensure safe production.

[0065] Embodiment 9

[0066] Based on the above embodiments, this embodiment provides an application example.

[0067] In the port coal transportation industry, the dumper is at the middle core hub of transportation, supporting railway transportation above and connecting to coal storage below. Its operating efficiency and stability are particularly important, directly affecting the stability of the entire port coal transportation process.

[0068] At present, the heavy vehicle positioning detection of the main platform of the tipping machine is mainly realized by the input photoelectric tube and the output photoelectric tube. There are technical problems with poor stability in this field. The following technical problems exist during operation: 1. Affected by factors such as coal type, coal humidity, and weather, when there is a lot of coal dust during on-site operations, it will affect the photoelectric tube signal and cause signal loss, resulting in interruption of the automatic operation process and reduced overall operation efficiency; 2. When the photoelectric tube fails, temporary control measures are generally not adopted based on the safety of the equipment, and only repairs can be carried out, which increases the equipment failure time. 3. When the tipping machine is flipped, the original photoelectric tube is affected by the mechanical structure, and the detection signal will be blocked and lost, making it impossible to detect the entire flipping action. The above problems require companies to actively explore solutions.

[0069] Guided by the above-mentioned on-site problems and adhering to the concept of solving practical problems in a simple, effective and stable way, we conduct special research to achieve more accurate heavy vehicle positioning detection on the tipping machine platform, car position offset detection during the entire tipping machine operation process, and rapid switching of photoelectric tubes when failure occurs to reduce fault handling time.

[0070] Through on-site operations and actual testing, it was found that whether laser or ultrasonic detection methods are used, the influence of coal dust on the signal cannot be effectively eliminated, and the stability is not high. By observing the drawing dimensions of different models of C64, C70, and C80, it was found that the spacing a between the single wheel groups of the C70 and C80 single-section carriages is 1830mm, the spacing between the single wheel groups of the C64 single-section carriage is 1750mm, and the distance c between the two wheel groups of the carriage is more than 8000mm. Through measurement, it was found that the positioning deviation of the carriage on the platform was very small each time, and the wheel position was basically fixed. Therefore, according to the carriage size data (see Figure 4 , Table 1) and actual on-site measurement data, the present application finally proposes a solution to realize platform heavy vehicle positioning detection by using proximity detection switches (first proximity sensor and second proximity sensor) to detect wheels (see Figure 1 ), related flow chart (see Figure 5 ).

[0073] A car tipper is a large-scale mechanical equipment used to tip and unload bulk materials from railway open wagons. It is a loading and unloading machine that can flip or tilt rail vehicles to unload materials. It is suitable for ports with large transportation volumes and metallurgy, coal, thermal power, etc.

[0074] As a large-scale mechanical equipment used to unload bulk materials from railway open wagons, the car tipper can flip or tilt the rail vehicle to unload materials. It is suitable for ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. In order to ensure the accurate position of the car tipper, it is necessary to perform positioning and calibration on the car tipper.

[0075] The car tipping machine system is a large-scale mechanical equipment used to tip and unload bulk materials from railway open wagons. It is suitable for ports, power plants, metallurgy and other industries. Early car tipping machines could only tip and unload one wagon at a time, but now the largest car tipping machine can tip and unload four wagons at a time. The car tipping machine system is generally composed of a car tipping machine, a positioning car / pusher and auxiliary devices. The car tipping machine is used to tip the railway open wagon to a certain angle to unload the bulk materials inside, and the positioning car or pusher is used to pull the train and position the wagon onto the car tipping machine. Each time the positioning car or pusher pulls and positions the train onto the car tipping machine, the car tipping and unloading by the car tipping machine is called an operation cycle.

[0076] According to the position of the wheel 200 of the platform carriage 500 on site, the position of the proximity switch bracket 400 is installed, and the proximity switch 100 is adjusted to the position of the edge of the detection wheel, while ensuring that there is a safe detection range of about a preset distance, such as 5-10cm, in the east and west directions to eliminate the impact of slight deviation in the positioning of the platform carriage and ensure signal stability during the entire tipping process. The power supply and signal of the detection switch are connected to the remote station under the tipping machine platform nearby.

[0077] The signals of the two proximity switches are connected in series and used as the platform wheel positioning detection point. In the control program, they are connected in series with the photoelectric tube signal at the entrance and exit of the tipping machine as the platform heavy vehicle positioning detection signal to participate in the positioning vehicle and tipping machine operation execution conditions, thereby forming a more accurate positioning detection. In addition, when the tipping machine starts the automatic counterweight operation, the first cycle is to pull and position the platform heavy vehicle. There is no carriage on the platform and the wheels cannot be detected. Therefore, relevant settings are made in the program logic to shield the platform wheel positioning detection of the first cycle, and the photoelectric tube detection is used to start the joint detection from the second cycle.

[0078] In the operation program logic, when the platform has positioned the heavy vehicle, the tipper will detect the positioning signal before flipping over. If there is no feedback signal, the preset time will be delayed, for example 2s, to issue an alarm. In order to ensure safe monitoring of the entire flipping operation, real-time detection and alarm of the platform car position during the flipping of the tipper is added. When the car position is offset due to abnormalities in the car press or the support plate, timely alarm prompts can be provided.

[0079] The platform wheel alignment detection signal display is added to the dumper interface to facilitate operators to observe more intuitively. At the same time, a temporary switching button is added. When the coal dust on the site seriously affects the photoelectric tube signal or the photoelectric tube fails and causes the signal to be lost, the on-site personnel can verify and confirm and quickly switch through the screen button operation to temporarily shield the photoelectric tube signal, thereby reducing the fault handling time and achieving improved production efficiency while ensuring safety.

[0080] The technical solution of this embodiment can effectively solve the problem of coal dust affecting the photoelectric tube signal, provide more accurate positioning of heavy vehicles on the tipping machine platform, realize the car position offset detection function throughout the tipping operation, and reduce the fault handling time by fast switching when the photoelectric tube fails, thereby improving operation efficiency and ensuring the orderly advancement of safe production.
