[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, and to fully understand and implement how the present invention applies technical means to solve technical problems and achieve the corresponding technical effects, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all of the embodiments. The embodiments of the present invention and the various features in the embodiments can be combined with each other without conflict, and the technical schemes formed are all within the scope of protection of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0027] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] When the car tipper unloads a coal train, the car press and the car support plate are needed to clamp the train together. After clamping, the entire train car is turned over and the coal is dumped into the hopper. If the pressing device is not pressed tightly during the unloading process, the train may be at risk of derailment, causing serious machine damage accidents and seriously affecting production, so the stability and effectiveness of the pressing facility detection device are extremely important. At present, the car support plate detection device of the car tipper is a spring connecting rod structure. When the car support plate is close to the car, the pressure rod is pressed down and the proximity switch is triggered. This open detection form has many problems and is easily affected by coal blocks and dry fog on site, causing mechanical mechanisms to rust, deform, or jam, etc., resulting in operation interruption, and problems cannot be quickly handled after they occur, affecting operation efficiency. There is a technical problem in this field that open detection is easily affected by coal blocks.

[0029] Hereinafter, the technical solution of the present application will be described in conjunction with specific embodiments.

[0030] Embodiment 1

[0031] Figure 1 Schematic diagram of the external structure of a vehicle board state detection device provided in an embodiment of the present application. Figure 1 As shown, in the technical solution of this embodiment, a vehicle backrest status detection device is provided, and the device includes: a bottom plate, an outer shell, a sealing plate and a detection component; the bottom plate is connected to the vehicle backrest; the sealing plate seals the outer shell and the bottom plate to form a sealed space; the detection component is arranged in the sealed space.

[0032] In the scenario where the tipping machine unloads the coal train, the car plate detection device is susceptible to the harsh environment on site, such as salt spray and coal dust, which leads to problems such as rust, deformation, and jamming of the mechanical mechanism, resulting in interruption of operation and difficulty in rapid processing. In the technical solution of this embodiment, a bottom plate is set to connect the car plate, and the outer shell and the bottom plate are sealed with a sealing plate to form a sealed space, and the detection component is placed in the sealed space. The bottom plate is made of 316 stainless steel, which is corrosion-resistant; the outer shell is made of wear-resistant polyurethane material, and the internal seal is achieved by fixing the pressure plate and the bottom plate. In this way, it is difficult for external salt spray and coal dust to enter the sealed space, effectively protecting the detection component. As a result, the service life of the internal components of the car plate detection device is improved. The stainless steel bottom plate resists corrosion, and the wear-resistant polyurethane outer shell blocks salt spray and coal dust and is flexible, and acts as a buffer when the car plate is close to the carriage. When the carriage squeezes the outer shell, the internal detection component is not affected by the harsh external environment. The thickened wear-resistant polyurethane protective layer slows down wear, reduces maintenance requirements, improves the long-term stability of the detection device, ensures the continuity of the tipping machine operation, and saves maintenance costs and time.

[0033] Embodiment 2

[0034] On the basis of the above embodiment, the device further includes: a fixing hole; the bottom plate is connected to the vehicle backing plate, including: fixing the bottom plate to the vehicle backing plate through the fixing hole.

[0035] It is necessary to reliably fix the backrest plate status detection device on the backrest plate to ensure that the equipment does not loosen or fall off during the operation of the tipping machine, thereby ensuring the detection accuracy. In the technical solution of this embodiment, fixing holes are set on the bottom plate, and the bottom plate is fixed to the hollow part of the backrest plate through the fixing holes using bolts and other connectors. The bottom plate of the detection device is made of 316 stainless steel and is in firm contact with the backrest plate. Thus, it can provide a guarantee for the stable operation of the backrest plate status detection device. During the process of tipping the coal train, the backrest plate is subjected to tremendous pressure and impact force. The fixing method of the fixing holes enables the detection device to withstand the test of harsh working conditions, ensuring that the detection signal is accurate and reliable. At the same time, it is convenient for on-site personnel to quickly install and replace, reducing the impact of equipment failure on work efficiency.

[0036] Embodiment 3

[0037] Based on the above embodiment, a side of the shell away from the bottom plate is higher than a preset distance from the plane of the vehicle plate; and the length of the shell is greater than the distance between the two side pillars of the vehicle compartment.

[0038] Ensure that the backrest plate state detection equipment can adapt to the differences in the parking positions of train carriages of different models, and realize reliable detection of the tight state of the backrest plates of different models. In the technical solution of this embodiment, the side of the shell away from the bottom plate is set to be a preset distance higher than the plane of the backrest plate, and the length of the shell is greater than the distance between the two side pillars of the carriage. In this way, even if there are differences in the parking positions of the trains on the tipping machine, detection can be performed. Therefore, the technical solution of this embodiment has a wide range of applicability and can adapt to the tightness detection of the backrest plates of various models at different parking positions. When the tipping machine tipping over trains of different models, no matter how the parking position of the train changes, the detection device can accurately detect the tightness of the backrest plate, which improves the reliability and stability of the detection and provides guarantee for the safe and efficient operation of the tipping machine.

[0039] Embodiment 4

[0040] Figure 2 Schematic diagram of the internal structure of a vehicle board state detection device provided in an embodiment of the present application. Figure 2 As shown, on the basis of the above embodiment, the detection component includes a proximity switch, a detection spring and a support spring; the support spring is arranged between the base plate and the shell; the detection spring is arranged on the pressure plate inside the shell, and is used to transmit the deformation of the shell to the proximity switch when the shell is squeezed; the proximity switch is arranged on the base plate, and the position of the proximity switch corresponds to the position of the detection spring, and is used to accept the pressure of the detection spring on the proximity switch when the shell is squeezed.

[0041] In the vehicle plate detection scenario, a reliable method is needed to detect the close state of the vehicle plate and accurately trigger the detection signal to avoid the risk of train derailment due to inaccurate detection. In the technical solution of this embodiment, the detection component includes a proximity switch, a detection spring and a support spring. The support spring is arranged between the bottom plate and the shell. When the vehicle plate is close to the carriage, the shell drives the internal receiving plate to press down, and the rigid receiving plate moves downward to compress the support spring and the detection spring. The detection spring is arranged on the pressure plate inside the shell, and is used to transmit the deformation of the shell to the proximity switch when the shell is squeezed. The proximity switch is arranged on the bottom plate, and its position corresponds to the detection spring. When the shell is squeezed, it receives the pressure of the detection spring to trigger the signal. Therefore, when the vehicle plate is close to the carriage, the technical solution of this embodiment can accurately detect the close state of the vehicle plate and trigger the corresponding signal through the cooperation of this mechanical structure. In the process of dumping coal trains by the dumper, this design ensures the reliability of detection, and can timely and accurately feedback the state of the vehicle plate even in harsh working environments. Once the car plate is close to the car body, the detection spring can quickly transmit the deformation of the shell to the proximity switch, and the proximity switch triggers the output of the corresponding signal, providing a strong guarantee for the safe operation of the tipping machine. At the same time, this design also improves the sensitivity and accuracy of the detection, reducing the possible damage accidents caused by inaccurate detection.

[0042] Embodiment 5

[0043] On the basis of the above embodiment, the detection component further includes a detection baffle and a switch protection; the detection baffle is connected to the detection spring, the switch protection is arranged on the bottom plate, and the switch protection is arranged on both sides of the proximity switch.

[0044] In order to prevent the detection spring from directly pressing on the proximity switch when transmitting the shell deformation and causing damage, and to ensure the accuracy and stability of the detection signal. In the technical solution of this embodiment, the detection assembly also includes a detection baffle and a switch protection. The detection baffle is connected to the detection spring, and when the detection spring is squeezed, the detection baffle moves with the detection spring. The switch protection is arranged on the bottom plate and located on both sides of the proximity switch to prevent the detection baffle from directly pressing on the proximity switch during the movement. This not only protects the proximity switch, but also ensures that the movement of the detection spring can accurately trigger the proximity switch. Therefore, during the operation of the vehicle board, the setting of the detection baffle and the switch protection of the technical solution of this embodiment effectively protects the proximity switch and prolongs the service life of the proximity switch. At the same time, due to the presence of the detection baffle, the movement of the detection spring is more stable, and the deformation of the shell can be accurately transmitted to the proximity switch, which improves the accuracy and stability of the detection signal. In the frequent dumping and unloading operations of the tipping machine, this design ensures the reliability of the detection device, reduces the detection failure caused by the damage of the proximity switch, and improves the operation efficiency.

[0045] Embodiment 6

[0046] On the basis of the above embodiment, the detection component further includes: an air pressure sensor, which is arranged in the sealed space and is used to monitor the air pressure in the sealed space.

[0047] Improve the accuracy of judging the close state of the vehicle board, avoid misjudgment caused by single sensor failure, and ensure the safety and reliability of the tipping machine operation. In the technical solution of this embodiment, the detection component also includes an air pressure sensor, which is arranged in a sealed space. When the shell is pressed, the air pressure in the sealed space will increase; when the car body leaves the shell, the support spring will restore the shell to its original state and the air pressure will decrease. By monitoring the air pressure change in the sealed space, it is coordinated with the proximity switch to judge whether the car body is close to the vehicle board. Since the air pressure sensor and the proximity switch are different sensors, it is difficult for them to fail at the same time. Therefore, in the process of detecting the vehicle board, the air pressure sensor and the proximity switch of the technical solution of this embodiment cooperate with each other, which greatly improves the accuracy of judging the close state of the vehicle board. If the proximity switch fails, the air pressure sensor can be used as a backup detection means to judge whether the car body is close according to the air pressure change. This dual detection mechanism effectively reduces the risk of misjudgment and improves the safety and reliability of the tipping machine operation. In practical applications, even if one sensor has a problem, the other sensor can continue to work, providing buffer time for equipment maintenance and repair, and reducing the impact on production.

[0049] Figure 3 is a flow chart of a method for detecting a vehicle board state provided in an embodiment of the present application, such as Figure 3 As shown, in the technical solution of this embodiment, a method for detecting the state of a vehicle board is provided, the method comprising: obtaining a detection signal generated by a detection component; if two groups of detection signals are obtained, it is determined that the vehicle board is in close contact; if no group of detection signals is obtained, it is determined that the vehicle board is not in close contact; if only one group of detection signals is obtained, it is determined that the vehicle board is in close contact and that there is a signal fault.

[0050] Accurately judge the close state of the vehicle plate, and remind the maintenance personnel to check and repair in time when the signal is abnormal, so as to reduce the impact of equipment failure on production. In the technical scheme of this embodiment, the detection signal generated by the detection component is obtained. If two groups of detection signals are obtained, it is determined that it is close; if any group of detection signals is not obtained, it is determined that it is not close; if only one group of detection signals is obtained, it is determined that it is close and the signal is faulty and the maintenance personnel are reminded. By setting two groups of proximity switches to be connected to the PLC at the same time, the two groups of signals are output in parallel in the PLC, and judgment is made according to different signal conditions. This detection method can accurately judge the close state of the vehicle plate, and provides a reliable basis for the safe operation of the tipping machine. When the signal is abnormal, the maintenance personnel can be reminded in time, and the emergency maintenance needs can be converted into a predetermined maintenance plan, reducing the impact of equipment failure on production. During the operation of the tipping machine, the maintenance personnel can carry out targeted inspections and repairs according to the alarm information, which improves the maintenance efficiency and reduces the maintenance cost. At the same time, this design also improves the intelligence level of the equipment and enhances the stability and reliability of the equipment.

By setting two groups of proximity switches to be connected to the PLC at the same time, the two groups of signals are output in parallel in the PLC, and judgment is made according to different signal conditions.

[0059] Embodiment 10

[0060] Based on the above embodiments, this embodiment provides an application example.

[0061] When the car tipper unloads a coal train, the car press and the car plate are needed to clamp the train together, and then the entire train car is turned over to dump the coal into the hopper. If the pressing device is not pressed tightly during the unloading process, the train may derail, causing serious machine damage accidents and seriously affecting production. Therefore, the stability and effectiveness of the pressing facility detection device are extremely important.

[0062] At present, the backrest detection device of the tipping machine is a spring-link structure. When the backrest is close to the car body, the pressure rod is pressed down and the proximity switch is triggered. This open detection form has many problems and is easily affected by coal blocks and dry fog on site, causing the mechanical mechanism to rust, deform, or get stuck, resulting in operation interruption. Moreover, when problems occur, they cannot be dealt with quickly, affecting operation efficiency.

[0063] Develop a sensor for detecting the closeness of the vehicle plate. First, it can reliably detect the closeness of the vehicle plate. Second, it can resist the influence of harsh salt spray, coal dust, etc. on site and extend its service life. Third, it can simplify the switch form so that on-site personnel can deal with problems quickly when they occur.

[0064] This technical invention is developed for the detection of car approaching plate signals, and can realize reliable car approaching detection for different train models (C80, C64, C70, etc.) on site.

[0065] Explanation of the reference numerals: 10 is a signal detection spring, 20 is a wear-resistant polyurethane shell, 30 is an internal receiving plate, 40 is a switch protection, 50 is a detection baffle, 60 is a stainless steel bottom plate, 70 is a support spring, 80 is a proximity switch, 90 is a cable fixation, 100 is a device fixing accessory, and 110 is a shell fixing pressure plate.

[0066] About the overall appearance of the detection device. Figure 1 The figure is a schematic diagram of the external structure of a vehicle backrest status detection device disclosed in an embodiment of the present invention. The bottom plate 60 of the detection device is made of 316 stainless steel, and the outer shell 20 is made of wear-resistant polyurethane material. The latter is fixed to the bottom plate 60 by a pressure plate 110 and realizes internal sealing. The fixing bolt holes 100 at both ends of the detection device are installed and fixed in the hollow part of the vehicle backrest. During installation, the outermost side of the outer shell 20 exceeds the plane of the vehicle backrest by 5-8CM. After the vehicle backrest is close to the car body, the car body squeezes the outer shell 20, and the outer shell 20 is compressed together with the internal receiving plate, and the internal proximity switch 80 triggers the output.

[0067] About the internal structure of the detection device. Figure 2 The figure is a schematic diagram of the internal structure of a vehicle board state detection device disclosed in an embodiment of the present invention. Below the polyurethane shell 20 is an internal receiving plate 30 made of stainless steel, below which are fixedly installed, for example, 6 groups of support springs 70, below which are installed on a bottom plate 60, with a group of signal detection springs 10 on each side, and below the signal detection springs is a detection baffle 50, below which is, for example, a proximity switch 80, and on both sides of the proximity switch 80 are switch protections 40 to prevent the detection baffle 50 from directly pressing on the proximity switch 80.

[0068] This embodiment also includes an air pressure sensor, which is arranged in the sealed space. This embodiment achieves a certain degree of sealing through the bottom plate and the outer shell. When the outer shell is pressed, the air pressure in the sealed space will increase. When the car leaves the outer shell, the supporting spring will restore the outer shell to its original state, so that the air pressure decreases. This embodiment detects the air pressure change in the sealed space by setting an air pressure sensor, and can cooperate with the formation switch to determine whether the car is close to the car board. Since the air pressure sensor and the proximity switch are different sensors, it is difficult for them to fail at the same time. Therefore, the technical solution of this embodiment can determine whether the car is close to the car board based on the data of the air pressure sensor when the proximity switch only outputs one signal.

[0069] About the working principle of the detection device. Figure 3It is a flow chart of a method for detecting the state of a vehicle rest plate disclosed in an embodiment of the present invention. The detection device is fixed to the vehicle rest plate with pre-opened holes by bolts. The installation position is selected at the part close to the vehicle rest plate hydraulic cylinder and in contact with the side column of the carriage. The outermost side of the shell exceeds the plane of the vehicle rest plate by 5-8CM. The total length of the shell is 65CM, which is greater than the distance between the two side columns of the train carriage. This ensures that even if there are differences in the parking positions of the train on the tipping machine, detection can be performed. After the vehicle rest plate is close to the carriage, the flexible wear-resistant polyurethane shell 20 drives the internal receiving plate to press down, and the rigid receiving plate 30 moves downward to compress the support spring 70 and the signal detection spring 10. The detection baffle 50 below the signal detection spring 10 moves down and approaches the proximity switch 80. The proximity switch 80 triggers the output of the corresponding signal, indicating that the vehicle rest plate has been close.

[0070] The technical solution of this embodiment sets up two groups of proximity switches to be connected to the PLC at the same time. In the PLC, the two groups of signals are output in parallel. If both groups have signals, the plate approaching signal is output; if only one group of switches has signal output, the plate approaching signal and the output signal switch are checked and alarmed to remind the maintenance personnel that the signal switch may be damaged and to perform subsequent inspections and repairs; if both groups of switches have no signals, a non-approaching signal is output.

[0071] The beneficial effects of this embodiment include:

[0072] 1. This sensor device is set to 65CM, with a long horizontal detection range, which can adapt to and cover the position of the side pillars of different models of cars. It is suitable for a variety of models at different parking positions to detect the close proximity of the car board, so it has a wide range of applicability.

[0073] 2. The stainless steel base plate is combined with the wear-resistant polyurethane seal to effectively isolate the salt spray and coal dust on site, thereby increasing the service life of internal components. The thickened wear-resistant polyurethane protective layer slows down wear, reduces maintenance requirements, and improves the long-term stability of detection.

[0074] 3. The internal dual sensor redundant design enhances the reliability of detection. Even if a single sensor has a problem, the device can continue to operate until the planned shutdown maintenance, thus converting emergency maintenance needs into a scheduled maintenance plan and reducing the impact of equipment failure.

[0075] 4. The integrated design and bolt installation method make sensor replacement simple and quick, saving time and labor costs.
