[0033] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0034] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, rather than to describe a specific order.

[0035] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0036] Figure 1 This is a schematic diagram of the structure of a walking motor control device provided by an embodiment of the present disclosure. Figure 1 The travel motor control device includes a valve opening detection module 101, a central control module 102, a speed adjustment module 103, a valve control module 104, a switch module 105, a high-pressure unit 106, a low-pressure unit 107 and a valve 108.

[0037] The central control module 102 is respectively connected to the valve opening detection module 101, the speed adjustment module 103, the valve control module 104 and the switch module 105. The valve opening detection module 101 is configured to detect the opening size of the valve. The speed adjustment module 103 is configured to adjust the speed of the motor.

[0038] The valve control module 104 is connected to the valve 108. The valve control module 104 is configured to control the opening of the valve 108.

[0039] The control end of the switch module 105 is connected to the central control module 102 , the first input end of the switch module 105 is connected to the high voltage unit 106 , the second input end of the switch module 105 is connected to the low voltage unit 107 , and the selection end of the switch module 105 is connected to the valve 108 .

[0040] In this embodiment, the valve opening detection module 101 can detect the opening size of the valve 108 in real time and transmit this data to the central control module 102. The central control module 102 can calculate the required speed of the motor and the optimal opening to which the valve 108 should be adjusted based on the received valve 108 opening data and the preset working parameters, and generate relevant control instructions. The central control module 102 can send a control instruction to the speed adjustment module 103, and the speed adjustment module 103 controls the speed of the motor by adjusting the flow of hydraulic oil to meet actual working requirements. The central control module 102 can send a control instruction to the valve control module 104, and the valve control module 104 adjusts the opening of the valve 108 according to the instruction, thereby controlling the flow and pressure of the hydraulic oil entering the motor, thereby affecting the torque and travel speed of the motor.

[0041] For example, in a coke power plant, a tamping machine is an important equipment for reinforcing coke. Since coke generates a lot of heat during processing, the tamping machine needs to have sufficient power to cope with the working requirements in a high temperature environment. In this case, the travel motor control device can play an important role. The valve opening detection module 101 can monitor the opening size of the valve 108 in real time to ensure that the hydraulic oil can enter the motor smoothly. When the coke temperature rises and the power output of the motor needs to be increased, the central control module 102 will send an instruction to the valve control module 104 to increase the opening of the valve 108, thereby increasing the flow and pressure of the hydraulic oil. The speed regulation module 103 can adjust the speed of the motor according to the instructions of the central control module 102. In the early stage of tamping, a lower speed is required for smooth operation. In the later stage of tamping, in order to speed up the progress of the operation, the speed of the motor needs to be increased, and the speed regulation module 103 can achieve this purpose by adjusting the flow of hydraulic oil.

[0042] In this embodiment, the switch module 105 can select to receive power from the high-voltage unit 106 or the low-voltage unit 107 according to the instruction of the central control module 102. When a larger power output is required, the switch module 105 selects the high-voltage unit 106, and vice versa, the low-voltage unit 107. In this way, the system can flexibly adjust the power source according to actual needs, ensure the stable operation of the motor, and save energy consumption.

[0043] For example, when the tamping machine needs a larger power output, the opening of the valve 108 needs to be increased. The switch module 105 can select the high-pressure unit 106 as the power source. When the valve 108 is adjusted to the required opening, the low-pressure unit 107 is selected to maintain the opening state. Alternatively, when there is a gap in operation or the power output needs to be reduced, the switch module 105 can select the low-pressure unit 107 as the power source. This flexible power source selection method ensures that the tamping machine can operate stably under various working conditions while saving energy consumption.

[0044] In this embodiment, the valve opening detection module 101 can accurately detect the opening size of the valve 108 in real time, providing accurate data support for the central control module 102, so that the system can quickly respond and adjust the opening of the valve 108 according to actual needs, thereby ensuring that the motor obtains stable hydraulic power. The speed adjustment module 103 can accurately adjust the speed of the motor according to the instructions of the central control module 102 to meet the needs of different working scenarios. This precise speed control not only improves work efficiency, but also extends the service life of the motor. Through the intelligent control of the central control module 102, the valve control module 104 can quickly respond and adjust the opening of the valve 108 to ensure that the motor operates in the best state. The switch module 105 can intelligently select the high-pressure or low-pressure unit 107 to supply pressure to the valve 108 according to system requirements, further enhancing the safety and stability of the system. This intelligent design makes the entire control device more efficient and reliable, and suitable for various complex working environments.

[0045] like Figure 2 As shown, in one embodiment of the present disclosure, a walking motor control device further includes a pressure detection unit 109 and a speed detection unit 110 .

[0046] The pressure detection unit 109 is configured to detect pressure information of the motor.

[0047] The speed detection unit 110 is configured to detect speed information of the motor.

[0048] The pressure detection unit 109 and the speed detection unit 110 are both connected to the central control module 102 .

[0049] In this embodiment, the pressure detection unit 109 can detect the pressure information inside the motor, and the speed detection unit 110 can detect the real-time speed information of the motor. The two detection units can transmit the collected data to the central control module 102 in real time. The central control module 102 can make a comprehensive judgment on the operating state of the motor based on the received pressure information and speed information.

[0050] Exemplarily, when the tamping machine is operating, the pressure detection unit 109 monitors the pressure changes inside the motor in real time to ensure that the motor operates at an appropriate pressure. The speed detection unit 110 detects the speed of the motor to ensure that the tamping machine operates at a preset speed. When it is detected that the motor pressure is too high or the speed is abnormal, the central control module 102 can immediately take corresponding measures, such as reducing the opening of the valve 108, reducing the motor speed, etc., to avoid equipment damage or operation interruption, and ensure the stable operation of the motor. The central control module 102 can also issue instructions to the valve control module 104 and the speed adjustment module 103 according to the preset working parameters and the real-time detected data to achieve precise control of the motor. This closed-loop control system can adjust the operating state of the motor in real time to adapt to different work requirements.

[0051] The pressure detection unit 109 in this embodiment can obtain the pressure information of the motor in real time, ensuring that the motor operates under the optimal pressure state, avoiding equipment damage or performance degradation due to abnormal pressure. The speed detection unit 110 can accurately detect the speed information of the motor and provide accurate feedback to the central control module 102, so that the system can quickly adjust the operating state of the motor according to actual needs. This dual detection mechanism not only improves the operating efficiency of the motor, but also enhances the safety and stability of the system. At the same time, this intelligent monitoring method reduces maintenance costs and extends the service life of the equipment.

[0052] like Figure 2 As shown, in one embodiment of the present disclosure, a travel motor control device further includes a position limit protection module 111. The position limit protection module 111 is configured to monitor the position information of the motor.

[0053] The position limiting protection module 111 is connected to the central control module 102 .

[0054] In this embodiment, the limit protection module 111 monitors the position information of the motor to ensure that it operates within the preset travel range to prevent safety accidents or equipment damage caused by exceeding the range. The limit protection module 111 can monitor the position of the motor in real time through the position sensor, and transmit the position information to the central control module 102 in real time. When the central control module 102 detects that the motor is about to or has exceeded the preset travel range, the limit protection mechanism will be triggered immediately. At this time, the central control module 102 will send an instruction to the speed regulation module 103 to reduce the speed of the motor or completely stop the operation of the motor, and at the same time adjust the opening of the valve 108 through the valve control module 104 to ensure that the motor stops in a safe position.

[0055] Exemplarily, the limit protection module 111 may include a limit switch. The limit switch may be installed on the movement path of the motor. When the motor moves to a preset limit position, the limit switch will be triggered, generating a signal and transmitting it to the central control module 102. After receiving the signal from the limit switch, the central control module 102 may determine whether the motor has reached the preset limit position. If so, the central control module 102 will immediately issue an instruction to reduce the speed of the motor or completely stop the movement of the motor through the speed adjustment module 103, and adjust the opening of the valve 108 through the valve control module 104 to ensure that the motor stops at a safe position.

[0056] This embodiment can avoid the risk of collision with surrounding equipment or obstacles. This limit protection mechanism improves the safety and stability of the tamping machine and reduces the possibility of accidents.

[0057] In one embodiment of the present disclosure, the valve 108 comprises a proportional reversing valve.

[0058] The proportional reversing valve is connected to the switch module 105 and the valve control module 104 respectively.

[0059] In this embodiment, the proportional reversing valve is a device that can continuously and proportionally control the flow direction, flow rate and pressure of the fluid according to the size and direction of the input signal (such as the current signal). In the travel motor control device, the proportional reversing valve is a key valve component, which is connected to the switch module 105 and the valve control module 104 respectively. The switch module 105 can control the high pressure unit 106 or the low pressure unit 107 to provide power to the proportional reversing valve according to the instructions of the central control module 102 to adjust the opening. The valve control module 104 receives the instructions of the central control module 102, and controls the position of the valve core by adjusting the current signal input to the proportional reversing valve, thereby changing the flow direction, flow rate and pressure of the fluid. The proportional reversing valve drives the valve core to move through the internal electromagnet according to the received current signal, thereby realizing precise control of the fluid flow.

[0060] For example, the tamping machine needs to accurately control the direction, flow and pressure of the hydraulic oil to adjust the movement and strength of the tamping head. Through the instructions of the central control module 102, the valve control module 104 adjusts the input current signal of the proportional reversing valve in real time to achieve precise control of the hydraulic oil, thereby ensuring that the tamping machine can maintain stable performance and high working efficiency under different working conditions.

[0061] like Figure 2 As shown, in one embodiment of the present disclosure, the speed regulating module 103 includes a dual hydraulically controlled one-way valve 112 and a hydraulic pump 113 .

[0062] The double hydraulically controlled one-way valve 112 , the proportional reversing valve and the hydraulic pump 113 are all arranged on the oil delivery pipeline.

[0063] The proportional reversing valve is arranged between the double hydraulically controlled one-way valve 112 and the hydraulic pump 113 .

[0064] The central control module 102 is connected to the dual hydraulically controlled one-way valve 112 and the hydraulic pump 113 respectively.

[0065] In this embodiment, the hydraulic pump 113 can be used as a power source, which converts electrical energy or other forms of energy into hydraulic energy to provide power for the entire hydraulic system. In the speed regulation module 103, the hydraulic pump 113 can adjust the flow and pressure of the hydraulic oil. The double hydraulic control check valve 112 is a special control valve that can control the flow of hydraulic oil in two directions. When the rotation direction of the motor needs to be changed, the central control module 102 sends an instruction to the double hydraulic control check valve 112 to switch the flow direction of the hydraulic oil, thereby realizing the forward and reverse rotation of the motor. The double hydraulic control check valve 112 can also prevent the hydraulic oil from flowing back when the motor stops, ensuring the stable stop of the motor. The proportional reversing valve is located between the double hydraulic control check valve 112 and the hydraulic pump 113. It receives the instruction of the central control module 102 and changes the flow and direction of the hydraulic oil by adjusting the position of the valve core. When the speed of the motor needs to be adjusted, the central control module 102 sends a corresponding current signal to the proportional reversing valve, and the proportional reversing valve accurately controls the flow of the hydraulic oil according to the size and direction of the signal, thereby realizing continuous adjustment of the motor speed.

[0066] For example, in the tamping machine of the coke power plant, the tamping machine needs to adjust its travel speed and tamping force according to different work requirements. Through the central control module 102, the operator can adjust the input current signal of the proportional reversing valve in real time, so as to accurately control the flow and direction of the hydraulic oil, so that the tamping machine can operate according to the preset speed and force. For example, in the early stage of tamping, a lower travel speed and a larger tamping force may be required. At this time, the central control module 102 will adjust the proportional reversing valve so that the hydraulic pump 113 outputs a smaller flow and pressure; in the later stage of tamping, in order to speed up the progress of the operation, it may be necessary to increase the travel speed and reduce the tamping force. At this time, the central control module 102 will adjust the input signal of the proportional reversing valve accordingly, so that the hydraulic pump 113 outputs a larger flow and pressure. Through this precise speed adjustment method, the tamping machine of the coke power plant can maintain efficient and stable operating performance under different working conditions.

[0067] like Figure 2 As shown, in one embodiment of the present disclosure, a travel motor control device further includes an oil level monitoring module 114 .

[0068] The oil level monitoring module 114 is connected to the central control module 102 , and the oil level monitoring module 114 is configured to monitor the oil level in the oil storage tank.

[0069] In this embodiment, the sensor in the oil level monitoring module 114 can monitor the oil level in the oil tank in real time, or indirectly obtain the oil quantity information by measuring the weight of the oil. The sensor transmits the obtained oil quantity information to the central control module 102. This process can be carried out in a wired or wireless manner to ensure the real-time and accuracy of the data. After receiving the oil quantity information, the central control module 102 can perform corresponding processing and judgment. When the oil quantity is lower than the preset safety threshold, the central control module 102 can issue an alarm instruction message to remind the staff to replenish the oil in time or check whether there is an oil leak to ensure the normal operation of the equipment.

[0070] For example, since the tamping machine consumes a large amount of hydraulic oil during operation, the oil level in the oil tank must be monitored and replenished in real time. By installing the oil level monitoring module 114, the coke power plant can grasp the oil level in the oil tank in real time and take timely measures when the oil level is lower than the safety threshold, such as starting the spare oil tank or refueling, to ensure the normal operation of the tamping machine and avoid equipment failure or shutdown caused by lack of oil. This not only improves the reliability and stability of the equipment, but also reduces maintenance costs and production risks.

[0071] like Figure 2 As shown, in one embodiment of the present disclosure, a travel motor control device further includes an alarm module 115 .

[0072] The alarm module 115 is connected to the central control module 102 .

[0073] In this embodiment, the alarm module 115 can receive alarm instruction information from the central control module 102, which may include pressure information, speed information, position information, and oil quantity information of the motor. When the pressure of the motor is too high, the speed is abnormal, or exceeds the preset travel range, the alarm module 115 will immediately trigger the alarm mechanism and output an alarm signal. The alarm signal can be in the form of sound, light signal, email or text message, so that the operator can receive and process it in time.

[0074] For example, when the motor of the tamping machine fails and the pressure is too high, the alarm module 115 will immediately detect this abnormal situation, output sound and light signals, and send an alarm text message to the operator. After receiving the alarm, the operator can quickly take corresponding measures, such as stopping the machine for inspection, adjusting parameters, etc., to avoid further damage to the equipment or causing safety accidents. The alarm module 115 can also be connected to the monitoring system of the coke power plant to achieve remote monitoring and alarm, further improving the operating efficiency and management level of the equipment.

[0075] like Figure 2 As shown, in one embodiment of the present disclosure, a travel motor control device further includes a temperature detection module 116 and a lubrication module 117 .

[0076] The central control module 102 is connected to the temperature detection module 116 and the lubrication module 117 respectively.

[0077] The temperature detection module 116 is configured to detect hydraulic oil temperature and bearing temperature.

[0078] The lubrication module 117 includes a lubrication pump configured to reduce the temperature of the hydraulic oil and lubricate the bearings.

[0079] In this embodiment, the temperature sensor can monitor the temperature of the hydraulic oil and the temperature of the bearing in real time, and transmit the temperature information to the central control module 102. The central control module 102 can determine whether the temperature is abnormal according to the preset rules and thresholds. For example, when the temperature information exceeds the preset safety threshold, the central control module 102 can send this information to the alarm module 115 to start the alarm. At the same time, the central control module 102 can send instructions to the lubrication module 117 to start the corresponding cooling and lubrication measures. The lubrication pump in the lubrication module 117 will start working after receiving the instructions from the central control module 102. The lubrication pump delivers lubricant to the bearings and hydraulic devices to reduce the temperature of the hydraulic oil and lubricate the bearings to ensure the normal operation of the equipment.

[0080] For example, as the tamping machine runs for a long time, the temperature of the hydraulic oil and the temperature of the bearing will gradually increase. Once the temperature exceeds the preset safety threshold, the temperature detection module 116 will immediately send this information to the central control module 102. After analysis and judgment, the central control module 102 will send an instruction to the lubrication module 117 to start the lubrication pump. The lubrication pump quickly delivers lubricant to the bearing and hydraulic system, reduces the hydraulic oil temperature and lubricates the bearing, preventing equipment damage or performance degradation due to excessive temperature.

[0081] In this way, the tamping machine of the coke power plant can operate stably in a high temperature environment, improve production efficiency and reduce equipment failure rate. At the same time, this temperature detection and lubrication system can also extend the service life of the equipment and reduce maintenance costs.

[0082] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
