[0024] 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.

[0025] 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. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] 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.

[0027] In the car tipping machine operation system, the car tipping machine tilts the unloaded materials to the lower hopper, and the hopper conveys the materials to the belt conveyor through the feeding device, thereby realizing the material turnover of the carriage. However, the unloaded materials often accumulate on the hopper extension plate, affecting the normal operation of the car tipping machine. There is a technical problem in the art that it is difficult to detect the accumulation of materials on the hopper extension plate.

[0028] In the car tipper operation system, the car tipper, as the main equipment, plays a key role. The car tipper tilts the unloaded materials to the lower funnel, and the funnel transports the materials to the belt conveyor through the feeding device, thereby realizing the material turnover of the car. Figure 1 This is a schematic diagram of a tipping machine. Figure 1 , Figure 1 It includes an open-end pressure beam 1, a closed-end pressure beam 3, a tipper end ring 2, a support plate 4, a support beam 5, a platform beam 6, a tugboat group 7, a tugboat beam 8, a funnel 9, a funnel extension plate 10, a concrete foundation 11, a tipper platform 12, a side beam 13, and a train carriage to be tipped 14.

[0029] Figure 2 The figure is a schematic diagram of material accumulation of a dumper. Figure 2 As shown in the figure, during the unloading process, the material impacts the funnel, and the air is squeezed and blown back to cause a lot of dust, which causes serious pollution in the third layer of the pit. For this reason, a dust-proof funnel extension plate 10 is added to this area of ​​the tipping machine to solve the dust suppression problem of the third layer. During use, due to the blockage of the non-tipping side funnel grille and the fluidity of the material, there is often a phenomenon of excessive accumulation of material 15 on the funnel extension plate 10, resulting in material accumulation 16. During the tipping process of the tipping machine (such as Figure 2 ), the vehicle beam 5 will be squeezed with this part of the material, causing the funnel extension plate 10 to deform, and even causing the risk of crushing the outer cable tray. At the same time, it will cause material accumulation on the supporting wheel beam 8, burying the supporting wheel 7, causing drive overload and seriously affecting the service life of the supporting wheel 7.

[0030] The related technology uses two high material level detection devices: one is to install a mercury switch below the grille directly below the tipping machine, and the other is to install a radar on the surface of the tipping side hopper. Since both methods can only be used to detect the height of the material under the grille, when the non-tipping side hopper grille is blocked and excessive material is accumulated on the hopper extension plate 10, the hopper extension plate 10 area is a detection blind area, and detection protection cannot be achieved, which poses a serious risk.

[0031] Since the two existing high material level detection devices cannot detect the excessive accumulation of materials on the hopper extension plate 10 caused by the grid blocking, it is impossible to avoid the major hidden dangers of deformation of the hopper extension plate 10 and burial of the supporting wheel beam 8. The present invention designs a set of detection devices and control methods to realize alarm reminders when materials accumulate on the hopper extension plate 10. When the materials are seriously over the limit, the tipping machine system is controlled to promptly notify the extension plate 10 materials and the grid to be cleaned. This device is an effective supplement to the original high material level detection of the tipping machine.

[0032] like Figure 1 As shown: the tipper is in a horizontal state, the locomotive carriage 14 is fixed by the open end pressure beam 1, the closed end pressure beam 3 and the car board 4, and the tipper is turned over by the meshing of the gear ring. The tipper rotor is composed of the side beam 13, the car board beam 5, the platform beam 6 and the tipper end ring 2. The driving gear drives the rotor to turn along the supporting wheel 7. Figure 2 The figure shows the situation when the tipper turns over to the maximum tilting angle. When a large amount of material is piled up on the extension plate 10 of the tipper hopper, during the tipper turning process, the support beam 5 will squeeze the material on the extension plate 10, causing the extension plate 10 of the hopper to deform.

[0033] Hereinafter, the technical solution of the present application will be described in conjunction with specific embodiments.

[0034] Embodiment 1

[0035] Figure 3 is a schematic diagram of the installation of a funnel material detection device provided in an embodiment of the present application. Figure 4 is a front view of a funnel material detection device provided in an embodiment of the present application, Figure 5 1 is a top view of a funnel material detection device provided in an embodiment of the present application. Figures 3 to 5 As shown, in the technical solution of this embodiment, a funnel material detection device is provided, and the device includes: a detection bracket 106, one end of which is connected to the car beam of the tipping machine, and the other end is provided with an opening; a rotating shaft 108, which is installed in the opening of the detection bracket 106, and the axial direction of the rotating shaft is parallel to the axial direction of the tipping machine; a detection rod 105, which is vertically connected to the rotating shaft 108; a trigger stop iron 104, which is installed at one end of the detection rod 105; a switch bracket 102, one end of which is connected to the car beam of the tipping machine, and the other end is provided with an opening; a proximity switch 101, which is installed in the opening of the switch bracket 102, and can generate a trigger signal according to the trigger stop iron 104.

[0036] The technical problem to be solved in this embodiment is how to detect coal overflow from the extension plate of the hopper of the car tipper. The technical solution of this embodiment is to construct a hopper material detection device, where one end of the detection bracket is connected to the car beam of the car tipper, and the other end provides an installation position for the rotating shaft. The rotating shaft is installed in the opening of the detection bracket and its axis is parallel to the axis of the car tipper, ensuring that the detection rod can rotate stably around it. The detection rod is vertically connected to the rotating shaft. When there is coal overflow on the extension plate of the hopper of the car tipper, the material will touch the detection rod, causing the detection rod to rotate around the rotating shaft. The trigger stop iron is installed at one end of the detection rod, and moves with the rotation of the detection rod, changing the positional relationship with the proximity switch. The proximity switch is installed in the opening of the switch bracket, and can generate a trigger signal according to the trigger stop iron. The trigger signal indicates that there is coal overflow on the extension plate of the hopper of the car tipper.

[0037] When coal overflows from the hopper extension plate, the material touches the detection rod, which rotates around the rotating shaft, driving the trigger iron to move. The proximity switch generates a trigger signal after detecting the position change. This signal can promptly remind the staff that there is a coal overflow problem on the hopper extension plate. Without this detection equipment, it is difficult for the staff to detect coal overflow in time, which may cause the support beam to squeeze the material on the extension plate during the tipping process of the tipper, causing the hopper extension plate to deform, and even causing the risk of crushing the outer cable tray. At the same time, it causes material accumulation on the roller beam, burying the roller and causing drive overload, which seriously affects the service life of the roller. With this detection equipment, the staff can take cleaning measures at an early stage when the coal overflow problem occurs, avoiding these serious consequences and ensuring the stability and safety of the equipment.

[0038] Embodiment 2

[0039] On the basis of the above embodiment, the device further comprises: a restoring spring 109 , one end of which is connected to the detection bracket, and the other end of which is connected to the trigger stop iron 104 .

[0040] The technical problem to be solved in this embodiment is how to automatically reset the hopper material detection device after the trigger signal is generated. The technical solution of this embodiment is to set a recovery spring to connect the trigger stop iron and the detection bracket. When the spilled coal is cleared, the recovery spring can pull the trigger stop iron, so that the trigger stop iron is restored to a position aligned with the proximity switch under the action of the spring, eliminating the trigger signal, so that the detection device is automatically reset and ready for the next detection.

[0041] During the operation of the dumper, once the hopper extension plate is detected to have coal spilled, the trigger stop iron moves to generate a trigger signal for the proximity switch, and the staff will perform cleaning work after receiving the alarm. When the spilled coal is cleaned up, the recovery spring will quickly pull the trigger stop iron back to the initial position, restoring the detection equipment to normal state. In this way, the detection equipment can be self-reset and reused, without the need for frequent manual adjustment of the equipment status, thus improving work efficiency. At the same time, it also ensures the continued effectiveness of the detection equipment, and can promptly detect the next possible coal spill problem, further enhancing the stability and safety of the equipment.

[0042] Embodiment 3

[0043] Based on the above embodiment, the rotating shaft includes a pin with a hole.

[0044] The technical problem to be solved by this embodiment is how to improve the maintainability of the rotating shaft. The technical solution of this embodiment uses a hole with a pin as the rotating shaft, which can be more conveniently disassembled and installed when the rotating shaft needs to be maintained. The structure of the pin with a hole allows maintenance personnel to operate by inserting tools or pins, etc., which improves the efficiency and convenience of maintenance.

[0045] When the rotating shaft is worn or needs to be replaced, if an ordinary rotating shaft is used, a complicated disassembly and installation process is required, which consumes a lot of time and manpower. However, by using a pin with a hole as the rotating shaft, maintenance personnel can quickly disassemble it for inspection and replacement, greatly shortening the maintenance time. For example, if the rotating shaft fails, maintenance personnel can quickly use a tool to insert the hole of the pin with a hole, remove it from the detection bracket, replace the new pin with a hole, and then install the detection rod back to its original position. The whole process is simple and fast. This improves the maintainability of the equipment and improves production efficiency.

[0046] Embodiment 4

[0047] On the basis of the above embodiment, the device further includes: a switch locking nut 103 connected between the proximity switch 101 and the switch bracket 102 , and used for locking the proximity switch 101 to the switch bracket 102 .

[0048] The technical problem to be solved in this embodiment is: how to fix the proximity switch. The technical solution of this embodiment is to lock the proximity switch to the switch bracket by means of a switch locking nut. The switch locking nut can increase the connection stability between the proximity switch and the switch bracket, and prevent the proximity switch from loosening or falling off due to vibration and other reasons during the operation of the tipping machine, thereby ensuring that the proximity switch can accurately detect the position change of the trigger stop iron and generate a reliable trigger signal.

[0049] The tipping machine will generate large vibration and impact force during the turning process. If the proximity switch is not well fixed, it is easy to be offset or loose, resulting in inaccurate detection signals or even failure to detect the position change of the trigger stop iron. By firmly fixing the proximity switch to the switch bracket with the switch locking nut, these problems can be effectively avoided. Due to the use of the switch locking nut, the proximity switch always maintains a stable working state during long-term operation, accurately detects the position change of the trigger stop iron when the funnel extension plate overflows coal, and sends out a trigger signal in time, providing reliable alarm information for the staff. This not only improves the reliability of the detection equipment, but also provides a strong guarantee for the safe operation of the equipment.

[0050] Embodiment 5

[0051] Figure 6 is a flow chart of a funnel material detection method provided in an embodiment of the present application, such as Figure 6 As shown, in the technical solution of this embodiment, a funnel material detection method is provided, the method comprising: obtaining the flipping angle of the tipping machine and the trigger signal of the funnel material detection device of any one of the above embodiments; when the trigger signal is a preset signal, judging the prompt information to be output according to the preset correspondence between the flipping angle and the prompt information.

[0052] The technical problem to be solved in this embodiment is how to output prompt information. The technical solution of this embodiment is to determine the prompt information to be output by obtaining the flip angle and trigger signal of the tipping machine, combining the flip angle and the trigger signal, and the preset correspondence between the flip angle and the prompt information. When the trigger signal is a preset signal, different prompt information is output according to the different flip angles of the tipping machine, thereby providing more accurate and detailed situation feedback to the staff.

[0053] Taking the first phase of the Huanghua Port tipper system as an example, when the detection equipment detects that there is coal overflow on the funnel extension plate, a trigger signal is sent to the control system. At the same time, the system obtains the flip angle of the tipper. If the flip angle is within different ranges, different prompt information is output according to the preset corresponding relationship. For example, when the flip angle is greater than or equal to 60 degrees and less than 90 degrees, the prompt information of the high material level of the funnel is output, indicating that the material in the funnel is piled up high. When the flip angle is greater than or equal to 90 degrees and less than or equal to 160 degrees, the prompt information of excessive material on the funnel extension plate is output, prompting the staff to pay great attention and clean up the material on the extension plate in time to prevent the extension plate from deforming due to the squeezing of the material by the car beam. When the flip angle is less than 60 degrees or greater than or equal to 160 degrees, the prompt information of abnormal funnel material detection equipment is output, indicating that the detection equipment itself is faulty or interfered with by the outside world. In this way, the staff can take corresponding measures according to different prompt information, improve the pertinence and efficiency of the work, and further ensure the safe and stable operation of the tipper system.

[0054] Embodiment 6

[0055] Based on the above embodiment, the preset correspondence between the flip angle and the prompt information includes: when the flip angle is greater than or equal to 60 degrees and less than 90 degrees, the prompt information includes a high material level in the funnel; when the flip angle is greater than or equal to 90 degrees and less than or equal to 160 degrees, the prompt information includes excessive material on the funnel extension plate; when the flip angle is less than 60 degrees or greater than or equal to 160 degrees, the prompt information includes an abnormality in the funnel material detection equipment.

[0056] The technical problem to be solved by this embodiment is to clarify the preset correspondence between the flip angle and the prompt information. The technical solution of this embodiment defines the corresponding prompt information when the flip angle is in different ranges. When the flip angle is greater than or equal to 60 degrees and less than 90 degrees, the prompt information includes the high material level of the funnel; when the flip angle is greater than or equal to 90 degrees and less than or equal to 160 degrees, the prompt information includes that there is too much material on the funnel extension plate; when the flip angle is less than 60 degrees or greater than or equal to 160 degrees, the prompt information includes that the funnel material detection equipment is abnormal.

[0057] In actual car tipping machine operations, workers can more accurately judge the material conditions of the hopper and the working status of the detection equipment based on different flipping angles and corresponding prompt information. When the flipping angle is between 60 and 90 degrees, it indicates that the hopper is at a high material level, and workers can prepare in advance and pay attention to the flow of materials to prevent further accumulation of materials. When the flipping angle is between 90 and 160 degrees, it clearly indicates that there is too much material on the hopper extension plate, and workers will immediately take cleaning measures to avoid problems such as deformation of the extension plate and burying of the supporting wheels due to squeezing of materials by the beam. When the flipping angle is not within the above range, it indicates that the detection equipment is abnormal, and workers can check the equipment in time, troubleshoot, and ensure the normal operation of the detection equipment. This preset correspondence provides clear guidance for workers, improves work efficiency and safety, and ensures the stable operation of the car tipping machine system.

[0058] Embodiment 7

[0059] Figure 7 is a structural schematic diagram of a funnel material detection device provided in an embodiment of the present application, such as Figure 7 As shown, in the technical solution of this embodiment, a funnel material detection device is provided, which includes: an acquisition module, used to obtain the flipping angle of the tipping machine and the trigger signal of the funnel material detection equipment of any one of the above embodiments; a judgment module, used to judge the prompt information to be output according to the preset correspondence between the flipping angle and the prompt information when the trigger signal is a preset signal.

[0060] The technical problem to be solved in this embodiment is how to output prompt information. The technical solution of this embodiment is to determine the prompt information to be output by obtaining the flipping angle and trigger signal of the tipping machine, combining the flipping angle and the trigger signal as well as the preset correspondence between the flipping angle and the prompt information. When the trigger signal is a preset signal, different prompt information is output according to the different flipping angles of the tipping machine, thereby providing the staff with more accurate and detailed situation feedback. Taking the first phase of the tipping machine system of Huanghua Port as an example, when the detection equipment detects that there is coal overflow on the funnel extension plate, a trigger signal is sent to the control system. At the same time, the system obtains the flipping angle of the tipping machine. If the flipping angle is within different ranges, different prompt information is output according to the preset correspondence.

[0061] For example, when the flip angle is greater than or equal to 60 degrees and less than 90 degrees, a prompt message of a high material level in the hopper is output, indicating that the material in the hopper is piled high. When the flip angle is greater than or equal to 90 degrees and less than or equal to 160 degrees, a prompt message of excessive material on the hopper extension plate is output, prompting the staff to pay great attention and clean up the material on the extension plate in time to prevent the vehicle beam from squeezing the material and causing problems such as deformation of the extension plate. When the flip angle is less than 60 degrees or greater than or equal to 160 degrees, a prompt message of an abnormality in the hopper material detection equipment is output, indicating that the detection equipment itself has failed or is subject to external interference. In this way, the staff can take corresponding measures according to different prompt messages, thereby improving the pertinence and efficiency of the work and further ensuring the safe and stable operation of the tipping machine system. The other technical features and beneficial effects of this embodiment correspond to the above-mentioned embodiments and will not be repeated here.

[0069] Embodiment 9

[0070] Based on the above embodiments, this embodiment provides an application example.

[0071] In the car tipping machine operation system, the car tipping machine, as the main equipment, plays a key role. The car tipping machine tilts the unloaded materials to the lower funnel, and the funnel conveys the materials to the belt conveyor through the feeding device, thus realizing the material turnover of the carriage. Figure 1 , Figure 1 It includes an open-end pressure beam 1, a closed-end pressure beam 3, a tipper end ring 2, a support plate 4, a support beam 5, a platform beam 6, a tugboat group 7, a tugboat beam 8, a funnel 9, a funnel extension plate 10, a concrete foundation 11, a tipper platform 12, a side beam 13, and a train carriage to be tipped 14.

[0072] During the unloading process, the material impacts the hopper, and the air is squeezed and blown back to cause a lot of dust, which causes serious pollution in the third layer of the pit. For this reason, a dust-proof hopper extension plate 10 is added to this area of ​​the tipping machine to solve the dust suppression problem on the third layer. During use, due to the blockage of the non-tipping side hopper grille and the fluidity of the material, there is often a phenomenon of excessive accumulation of materials on the hopper extension plate 10. During the tipping process of the tipping machine (such as Figure 2 ), the vehicle beam 5 will be squeezed with this part of the material, causing the funnel extension plate 10 to deform, and even causing the risk of crushing the outer cable tray. At the same time, it will cause material accumulation on the supporting wheel beam 8, burying the supporting wheel 7, causing drive overload and seriously affecting the service life of the supporting wheel 7.

[0073] The related technology uses two high material level detection devices: one is to install a mercury switch below the grille directly below the tipping machine, and the other is to install a radar on the surface of the tipping side hopper. Since both methods can only be used to detect the height of the material under the grille, when the non-tipping side hopper grille is blocked and excessive material is accumulated on the hopper extension plate 10, the hopper extension plate 10 area is a detection blind area, and detection protection cannot be achieved, which poses a serious risk.

[0074] Since the two existing high material level detection devices cannot detect the excessive accumulation of materials on the hopper extension plate 10 caused by the grid blocking, it is impossible to avoid the major hidden dangers of deformation of the hopper extension plate 10 and burial of the supporting wheel beam 8. The present invention designs a set of detection devices and control methods to realize alarm reminders when materials accumulate on the hopper extension plate 10. When the materials are seriously over the limit, the tipping machine system is controlled to promptly notify the extension plate 10 materials and the grid to be cleaned. This device is an effective supplement to the original high material level detection of the tipping machine.

[0075] like Figure 1 As shown: the tipper is in a horizontal state, the locomotive carriage 14 is fixed by the open end pressure beam 1, the closed end pressure beam 3 and the car board 4, and the tipper is turned over by the meshing of the gear ring. The tipper rotor is composed of the side beam 13, the car board beam 5, the platform beam 6 and the tipper end ring 2. The driving gear drives the rotor to turn along the supporting wheel 7. Figure 2 The figure shows the situation when the tipper turns over to the maximum tilting angle. When a large amount of material is piled up on the extension plate 10 of the tipper hopper, during the tipper turning process, the support beam 5 will squeeze the material on the extension plate 10, causing the extension plate 10 of the hopper to deform.

[0076] For this purpose, the invention designs a set of detection devices (such as Figure 3 100): The detection device 100 welds the switch bracket 102 and the detection rod bracket 106 to the vehicle beam 5 (such as Figure 4 ). Figure 4 The device comprises: a proximity switch 101, a switch bracket 102, a switch locking nut 103, a trigger stop iron 104, a detection rod 105, a detection rod bracket 106, a rotating shaft cotter pin 107, a rotating shaft 108, an alignment restoring spring 109, a spring hook 110, and a spring balancing bracket 111.

[0077] When the material touches the detection rod 105 during the tipping process, the detection rod 105 deflects with the rotating shaft 108 as the rotation center, and the triggering iron 104 at the rear end of the detection rod 105 also deflects, and the signal of the proximity switch 101 is lost, triggering the alarm and control system (see Figure 5 ). The control system determines different control and alarm outputs according to the tipping position of the tipper when the signal is lost and the time when the signal is lost. When the part of the material is cleared, the detection rod 105 is released, and the detection rod 105 is restored to the trigger position of the proximity switch 101 under the action of the recovery spring 109, the alarm disappears, and the system returns to the normal operation mode.

[0078] The invention realizes the detection and control of excessive accumulation of materials on the funnel extension plate caused by factors such as funnel grille blockage, avoids the risk of side beams crushing the funnel extension plate, supporting wheels and drives being buried, and ensures the stability and safety of the equipment.

[0079] The solution of this embodiment has been used in the first phase of the Huanghua Port dumper system, and has repeatedly avoided problems such as extension plate collapse and supporting wheel burial caused by coal overflow from the funnel. The detection device can achieve self-reset and repeated use, and is relatively simple to install. When replacing wearing parts (proximity switch, detection rod, rotating shaft), only the nut needs to be disassembled and assembled, which is fast and simple. Each component is light and easy to implement. Only a cable from the proximity switch to the existing control system needs to be laid to achieve real-time feedback of the detection signal, and it is reliable and stable for on-site use.

[0080] On the basis of the above scheme, 1. The proximity switch of the detection device can be replaced by a travel switch. However, since the travel switch has internal contacts and external contact levers, it is prone to mechanical wear and jamming under harsh working conditions, resulting in unstable switch signals. 2. In order to avoid contact deformation, the detection rod detection device can be replaced by a rigid reed or a flexible hose at the end of the extension rod. 3. The overall detection structure can also adopt the design form of modifying the deviation switch, replacing the deviation switch lever with the form 2, to achieve other forms of derivation of the detection device.
