[0043] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] The following combination Figures 1-4 The present invention describes a winch mechanism safety protection method, device and operating machine.

[0045] Figure 1 This is one of the flow charts of the winch mechanism safety protection method provided by the present invention.

[0046] like Figure 1 As shown, an embodiment of the present invention provides a winch mechanism safety protection method, which can be executed by the control system of the winch mechanism and mainly includes the following steps:

[0047] 101. Detect the operating parameters of the drive components of the hoisting mechanism.

[0048] In a specific implementation, let's take a crane's hoisting mechanism as an example. The hoisting mechanism's drive components include the main pump, motor, and reducer brake. The drive components are essential for the proper functioning of the hoisting mechanism, and therefore, their proper functioning is a prerequisite for proper operation.

[0049] Among them, the way to detect the working parameters of the driving components of the hoisting mechanism can be through sensors. By judging the values ​​collected by the sensors, the current working parameters corresponding to different driving components can be determined. The working parameters include pressure values, temperature values, etc.

[0050] 102. Determine the working state of the drive component based on the working parameters.

[0051] After accurately detecting the operating parameters of the drive component, the operating state of the drive component can be determined based on the operating parameters. The operating state includes normal state and abnormal state. When the drive component is operating normally, its operating parameters are maintained within a certain range. For example, the pressure value, if maintained within a certain pressure range, indicates that the operating parameter at this time is normal. If the pressure value exceeds the pressure range, it indicates that an abnormal sudden change has occurred in the pressure value, and the operating state at that pressure value can be determined to be abnormal.

[0052] Among them, the method of determining the working status of the drive component through the working parameters can be to compare the currently detected working parameters with the preset safety parameters. If, after comparison, it is determined that the currently detected working parameters are within the reasonable parameter variation range, it indicates that the drive component is in a normal working state at this time. If the currently detected working parameters exceed the preset reasonable parameter variation range, it indicates that the parameter abnormality at this time is caused by the abnormality of the drive component, and it can be determined that the current working state is an abnormal state.

[0053] The method of determining the working state of the drive component based on the working parameters can also be through a machine learning model, which inputs the working parameter value fault diagnosis model and outputs the working state of the drive component. The working state includes normal state and abnormal state, and the working parameters include main pump working parameters, speed reducer brake working parameters, and motor working parameters, etc., wherein the fault diagnosis model is trained based on pre-constructed working parameter samples and working state samples. By jointly processing and analyzing the main pump working parameters, speed reducer brake working parameters, and motor working parameters, the working state of the drive component is determined according to the combination relationship of the three parameters. This can ensure the accuracy of the drive component fault diagnosis and also ensure the speed of fault diagnosis, avoid independent judgment of each working parameter separately, and then perform a fusion judgment, thereby improving the efficiency of fault diagnosis.

[0054] 103. If the working status is abnormal, the hoisting mechanism will be controlled to stop working and an abnormal prompt will be issued.

[0055] After determining the working status of the drive component through analysis and judgment of the working parameters, if the working status of the drive component indicates normal, the hoisting mechanism can be controlled to maintain normal operation. If the working status is abnormal, the hoisting mechanism needs to be controlled to stop working to ensure that no dangerous accidents occur. The abnormal working status defined at this time is a fault warning, that is, no actual fault has occurred. For example, if the working parameter is the pressure value, when the pressure value is 18 bar, it indicates that the drive component has failed. When determining the working status, the preset safety parameter can be 17 bar, so as to provide a fault warning before the actual fault occurs, to ensure that the object does not suddenly fall when a fault occurs, avoiding the occurrence of dangerous accidents.

[0056] In order to avoid the occurrence of dangerous accidents, in addition to controlling the winch mechanism to stop working, it is also necessary to issue an abnormal alarm prompt to promptly inform relevant personnel that the current winch mechanism has safety hazards and complete the inspection and maintenance of the winch mechanism in a timely manner.

[0057] The abnormality notification can be issued via a pop-up window on the crane's central control interface or displayed on other display interfaces. Alternatively, the abnormality notification can be issued via sound, light, or other means. The purpose of issuing an abnormality notification is to quickly and effectively inform relevant personnel of the abnormality, enabling rapid troubleshooting and prediction, thereby ensuring crane operating efficiency. Therefore, other notification methods are also possible, including text messages, and will not be described in detail in this embodiment.

[0058] This embodiment provides a winch mechanism safety protection method, which detects the working parameters of the drive component of the winch mechanism and determines the working status of the drive component based on the working parameters; if the working status is abnormal, the winch mechanism is controlled to stop working and an abnormal prompt is issued. Since the working status of the drive component is continuously detected when the winch mechanism is working, an abnormal prompt can be issued in time when the working status is abnormal, and the winch mechanism can be controlled to stop working, thereby effectively ensuring the working safety of the winch mechanism.

[0059] Figure 2 This is the second flow chart of the winch mechanism safety protection method provided by the present invention.

[0060] Furthermore, based on the above embodiment, Figure 2 As shown, the working parameters of the drive assembly in this embodiment include: the motor's descending side pressure value and the motor's oil leakage pressure value; correspondingly, based on the working parameters, the working state of the drive assembly is determined, including: when the motor's descending side pressure value is less than the preset descending side pressure value, and / or the motor's oil leakage pressure value is greater than the preset oil leakage pressure value, it is determined that the motor's working state is abnormal. Among them, the motor's descending side pressure value refers to the pressure value of the motor's descending side oil port. The motor is divided into two sides, the ascending side and the descending side. In this embodiment, the pressure value of the motor's descending side oil port is selected for detection. The motor is directly or indirectly connected to the winch, and the winch can lift or lower heavy objects through a wire rope. The motor has two working oil ports. If the hydraulic oil enters the motor through different oil ports, the winch connected to the motor will rotate in different directions. The oil port where the motor causes the winch to lift heavy objects is called the ascending side of the motor, and the side that lowers heavy objects is called the descending side.

[0061] Specifically, after the engine is started, the motor's downside pressure value and the motor's oil leakage pressure value are detected, wherein the detection order of the motor's downside pressure value and the motor's oil leakage pressure value is not distinguished, and they can be detected sequentially or simultaneously, without specific limitation. After the motor's downside pressure value is detected, the motor's downside pressure value is compared with the preset downside pressure value. If the motor's downside pressure value is greater than or equal to the preset downside pressure value, it operates normally. If the motor's downside pressure value is less than the preset downside pressure value, it indicates that the motor is working abnormally at this time. Under normal circumstances, the preset downside pressure value can be selected as 8 bar. That is, when the motor's downside pressure value is less than 8 bar, it indicates that the motor is working abnormally at this time. Real-time detection can also be started after the operating machine is powered on and before the engine is started. By actively detecting, the risk of the hoisting mechanism working can be effectively reduced, and the absolute safety of the hoisting mechanism can be guaranteed.

[0062] Similarly, when the motor's oil drain pressure is detected, the motor's oil drain pressure is compared with a preset oil drain pressure value. If the motor's oil drain pressure value is less than or equal to the preset oil drain pressure value, it indicates that the motor is operating normally. If the motor's oil drain pressure value is greater than the preset oil drain pressure value, it indicates that the motor is operating abnormally. For example, the preset oil drain pressure value may be 3 bar. That is, when the motor's oil drain pressure value is greater than 3 bar, it indicates that the motor is operating abnormally.

[0063] Among them, when either the motor's down-side pressure value or the motor's oil drain pressure value is abnormal, it indicates that the motor is working abnormally at this time. If both are abnormal, it also indicates that the motor is in an abnormal working state at this time.

[0064] Furthermore, based on the above embodiment, Figure 2 As shown, in this embodiment, when the motor's down-side pressure value is less than a preset down-side pressure value, and / or when the motor's oil drain pressure value is greater than the preset oil drain pressure value, an abnormality prompt is issued, including: determining the abnormal location of the motor; and issuing an abnormality prompt including the abnormal location. Specifically, when the motor's down-side pressure value is less than the preset down-side pressure value, the abnormality prompt is issued, including: issuing a motor down-side cavitation prompt; and when the motor's oil drain pressure value is greater than the preset oil drain pressure value, the abnormality prompt is issued, including: issuing a motor oil drain pressure exceeding standard prompt.

[0065] Specifically, when the motor's operating state is abnormal, as determined by detecting the pressure value on the motor's descent side, it can be determined that the abnormality is air suction. That is, when the pressure value on the motor's descent side is less than 8 bar, it can be determined that the motor's descent side is air suctioning. To ensure the safe operation of the hoisting mechanism, the hoisting mechanism is controlled to stop and an abnormality alert is issued. Since the abnormality is air suction, the motor's descent side air suction abnormality alert is directly issued, thereby improving maintenance efficiency for maintenance personnel.

[0066] Similarly, when the motor's oil drain pressure is detected as abnormal, the motor's operating status can be determined to be excessive. Specifically, when the motor's oil drain pressure exceeds 3 bar, it can be determined that the motor's oil drain pressure is excessive, resulting in a decrease in the motor's volumetric efficiency. To ensure the safe operation of the hoisting mechanism, the hoisting mechanism must be stopped and an abnormality alert issued. Since the abnormality is excessive, a direct motor oil drain pressure abnormality alert is issued, allowing maintenance personnel to quickly understand the cause of the abnormality and promptly complete repairs.

[0067] The abnormality notification can be issued through a pop-up window that directly displays the abnormality cause, allowing relevant personnel to clearly view the current abnormal status and cause. It can also be directly displayed on other display interfaces, as long as the current abnormal status and cause can be clearly and promptly viewed by relevant personnel.

[0068] Furthermore, based on the above embodiment, Figure 2 As shown, in this embodiment, after determining that the working state of the motor is abnormal, the method further includes: recording the number of abnormalities of the motor; and issuing a motor replacement prompt when the number of abnormalities is greater than a preset number.

[0069] Specifically, by detecting the motor's downdraft pressure and oil drain pressure, if an abnormal motor operating state is detected, the system can also record the number of motor abnormalities and the time of the abnormality. The time refers to the moment when the motor abnormality occurs, and the number of motor abnormalities can be recorded separately, such as the number of abnormal downdraft air suction and the number of abnormal oil drain pressure exceeding the standard. If the number of abnormalities exceeds a preset number, it indicates that the motor may have a serious fault, and a motor replacement prompt is issued, allowing the motor to be replaced in a timely manner to ensure the safe operation of the hoisting mechanism.

[0070] Among them, the number of abnormal air suction on the motor's descending side and the number of abnormal oil leakage pressure exceeding the standard of the motor are recorded separately. When the number of abnormalities of either one is greater than the preset number, a prompt to replace the motor is issued, thereby completing the detection of abnormal status of the motor more timely and ensuring the absolute safety of the winch mechanism.

[0071] The motor replacement reminder can be sent via text message to the operator's handheld smart device, such as a mobile phone. Alternatively, the motor replacement message can be displayed on the crane's central control display, or a fault light can be used to alert the operator that a motor replacement is required. As long as the operator is effectively informed and the motor replacement is completed promptly, it will be sufficient.

[0072] Furthermore, based on the above embodiment, Figure 2 As shown, the working parameters of the driving component in this embodiment include: the servo pressure value of the deceleration brake; correspondingly, based on the working parameters, the working state of the driving component is determined, including: when the servo pressure value of the deceleration brake is less than the preset servo pressure value, it is determined that the deceleration brake is abnormal.

[0073] Specifically, the driving assembly of the hoisting mechanism also includes a speed reducer brake. The main function of the speed reducer brake is to act as a brake to ensure the safety of the hoisting mechanism. The main function of detecting the servo pressure value of the speed reducer brake is to ensure that the speed reducer brake is always in a normal working state. After the servo pressure value of the speed reducer brake is detected, the detected servo pressure value is compared with the preset servo pressure value. If the servo pressure value of the speed reducer brake detected is less than the preset pressure value, it indicates that there is a hidden fault in the speed reducer brake at this time. At this time, the hoisting mechanism will be stopped immediately and an alarm will be issued to prompt the operator to perform fault detection and maintenance to ensure the absolute working safety of the hoisting mechanism. For example, the preset pressure value can be 18 bar, and ensuring that the servo pressure is greater than 18 bar can also effectively prevent the speed reducer brake from wearing and avoid the risk of damage to the speed reducer brake.

[0074] Furthermore, based on the above embodiment, Figure 2 As shown, the working parameters of the driving component in this embodiment include: the hydraulic oil temperature of the main pump hydraulic system; correspondingly, based on the working parameters, the working state of the driving component is determined, including: when the hydraulic oil temperature of the main pump hydraulic system is lower than or equal to the preset hydraulic oil temperature, it is determined that the main pump hydraulic system is abnormal.

[0075] Specifically, the hydraulic oil temperature of the main pump hydraulic system is monitored. In low-temperature environments, the viscosity of the hydraulic oil is higher, leading to a significant delay in locking the brakes and hydraulic system, potentially causing the hook to slip or damage to the motor of the hoisting mechanism. Therefore, after the crane is powered on, the hydraulic oil temperature corresponding to the main pump hydraulic system must be monitored. Based on the current hydraulic oil temperature, a determination is made as to whether to heat the hydraulic oil. First, the hydraulic oil temperature must be compared with the preset oil temperature. A temperature of -25°C or less indicates that the low temperature environment has caused the hydraulic oil temperature to be too low, making it difficult for the hydraulic oil to meet the operating requirements of the hoisting mechanism. Therefore, the hydraulic oil must be heated. Before performing this heating, the main pump hydraulic system must be confirmed to be abnormal. Once this is confirmed, the hoisting mechanism is stopped.

[0076] Furthermore, based on the above embodiment, Figure 2 As shown, in this embodiment, after determining that the main pump hydraulic system is abnormal, it also includes: starting the engine for preheating to increase the hydraulic oil temperature; when the hydraulic oil temperature is higher than the preset hydraulic oil temperature, the auxiliary pump is used to load the overflow to heat the hydraulic oil temperature until the hydraulic oil temperature reaches the preset safety temperature.

[0077] Specifically, when it is detected that the hydraulic oil temperature is less than or equal to -25 degrees Celsius, it indicates that the hydraulic oil needs to be heated. The hydraulic oil temperature can be increased by starting the engine oil preheating process. Preheating includes electric heating and other methods. When the hydraulic oil temperature is greater than -25°C, one-touch heating can be performed. Press the one-touch heating button to control the auxiliary pump to load the overflow. The current value is controlled at 300-500mA. The heating power P = pressure difference * flow = 30MPa * 85L / min = 42.5kW. At this time, the motor flushing oil is heated. After the oil temperature rises to the preset safety temperature, the heating is automatically terminated to prevent overheating. The one-touch heating method can quickly realize the hydraulic oil temperature control and effectively improve the working efficiency of the winch mechanism.

[0078] For example, the temperature range for controlling the auxiliary pump to load overflow is -25℃-3℃, and the preset safety temperature can be 3℃. That is, when the hydraulic oil temperature is between -25℃-3℃, the auxiliary pump is controlled to load overflow and increase the hydraulic oil temperature. When the hydraulic oil temperature is increased, the main pump current is proportionally limited to prevent the risk of motor air absorption increased by low-temperature high-speed operation. At the same time, all actions of the hoisting mechanism are restricted during the heating process. When the hydraulic oil temperature rises to the preset safety temperature, such as 3℃, the heating is stopped, indicating that the hydraulic oil temperature has reached the operating temperature. During the mechanical operation of the hoisting mechanism, due to the heat generated by the engine, the hydraulic oil temperature will be kept above the preset safety temperature to ensure the normal hydraulic oil temperature.

[0079] Furthermore, based on the above embodiment, Figure 2 As shown, in this embodiment, after the hydraulic oil temperature reaches the preset safety temperature, it also includes: when the hoisting mechanism is detected to be actuated for the first time, a safety operation prompt is issued.

[0080] Specifically, after the hydraulic oil is heated to a preset safety temperature via one-touch heating, the system checks whether the hoist mechanism is operating for the first time. If so, a safety operation prompt is issued, such as: "The hydraulic oil temperature is low. It is recommended that the hoist be operated without load for 2 minutes." This safety operation prompt heats up the hoist motor, brake, and other piping, ensuring the hoist mechanism maintains its normal operating temperature, thereby further ensuring safe operation of the hoist mechanism.

[0081] Based on the same general inventive concept, the present invention also protects a hoisting mechanism safety protection device. The hoisting mechanism safety protection device provided by the present invention is described below. The hoisting mechanism safety protection device described below and the hoisting mechanism safety protection method described above can be referenced to each other.

Since the working status of the driving component is continuously detected when the winch mechanism is working, an abnormal prompt can be issued in time when the working status is abnormal, and the winch mechanism can be controlled to stop working, thereby effectively ensuring the working safety of the winch mechanism.
