[0002] The buffer is used to buffer the longitudinal impact and vibration caused by the change of traction during the operation of the crane or the collision between vehicles during starting, braking and shunting operations. The buffer has the function of dissipating the impact and vibration between vehicles, thereby reducing the damage to the vehicle structure and loaded cargo. Common failures of the liquid-gas buffer include: when the metal structure outside the buffer is damaged, it will cause oil or gas leakage, which will significantly reduce the performance of the buffer.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0042] Example 1

[0043] A liquid-gas buffer with an intelligent buffer remote monitoring system, see Figure 1 , the specific structure and functions are as follows:

[0044] Jacket 8: The outer structure of the liquid-gas buffer provides overall mechanical strength and protection, ensuring the safety and stability of internal components.

[0045] Piston rod 3: Installed at the left end of outer sleeve 8, plays the role of transmitting force and motion. Its inner cavity is designed to accommodate isolation piston 5.

[0046] Isolation piston 5: Installed in the inner cavity of piston rod 3, it plays the role of separating nitrogen cavity and oil cavity. The left end of the piston forms a nitrogen cavity, and the right end forms an oil cavity to ensure the normal operation of the liquid-gas buffer.

[0047] Cylinder bottom 10: the bottom structure of the device, located at the end of the oil chamber away from the isolation piston 5, providing support and sealing the oil chamber.

[0048] Pressure sensor 9: Installed at the left end of the cylinder bottom 10, it monitors the pressure changes in the oil chamber in real time. The sensor can provide accurate pressure data to ensure that the liquid-gas buffer operates within a safe range.

[0049] Distance sensor 11: It is also installed at the left end of the cylinder bottom 10, parallel to the pressure sensor 9, and is responsible for monitoring the displacement of the piston rod 3. The data of this sensor is crucial for evaluating the working status of the buffer.

[0050] Integrated transmission module 12: Installed at the right end of the cylinder bottom 10, it is responsible for processing and transmitting the data collected by the pressure sensor 9 and the distance sensor 11. The module is connected to the two sensors through electrical connections to ensure real-time transmission and accuracy of the data.

[0051] Wireless communication: The integrated transmission module 12 supports wireless communication function to send real-time monitoring data to the remote monitoring platform. The communication method can include a variety of technologies, such as Wi-Fi, Bluetooth, LoRa or cellular network, to achieve timely data update and remote access.

[0052] Monitoring platform: The monitoring platform is a system that receives, stores and analyzes data from the integrated transmission module 12. Users can use this platform to monitor the working status of the liquid-gas buffer in real time, perform data analysis, fault diagnosis, and set alarm thresholds.

[0053] Through the above technical solution, the liquid-gas buffer of the intelligent buffer remote monitoring system can achieve efficient real-time monitoring and data analysis, greatly improving the safety and operating efficiency of the equipment.

[0054] In a specific embodiment, an inner plug 2 and a ram 1 are installed in sequence at the left end of the piston rod 3. The inner plug 2 is located at the left end of the piston rod 3 and is responsible for closing the opening of the piston rod to form a sealing part of the nitrogen chamber. The design of the inner plug 2 ensures the effective sealing of nitrogen and prevents leakage. The ram 1 is installed at the leftmost end of the inner plug 2. The ram 1 is used to transmit external impact force and can effectively contact the buffered object to play a buffering role. The interior of the outer sleeve 8, the right end of the inner plug 2 and the left end of the isolation piston 5 together form a closed nitrogen chamber. This cavity is specifically used to load nitrogen to ensure that the nitrogen can effectively absorb and buffer the impact force when the liquid-gas buffer is working.

[0055] During the buffering process, when the external impact force acts on the impact head 1, the impact head pushes the inner plug 2 and the piston rod 3 to move to the right, thereby moving the isolation piston 5, thereby changing the volume of the nitrogen chamber. This process allows the nitrogen to generate a reaction force through compression, effectively slowing down the transmission of the impact force and improving the impact resistance of the equipment.

[0056] In a specific embodiment, a mandrel seat 6 is installed at the right end of the piston rod 3; an inner hole is provided inside the mandrel seat 6, and a mandrel 7 is inserted in the inner hole. The mandrel is tapered, and the right end of the mandrel 7 is connected to the right end of the outer sleeve 8. The inner hole of the mandrel seat 6 and the tapered mandrel 7 form an annular throttling gap, and when the hydraulic oil passes through the throttling gap, a damping effect is generated; the inside of the outer sleeve 8 and the right end of the piston rod 3 and the left end of the cylinder bottom 10 together form an oil chamber for containing hydraulic oil; the hydraulic oil plays an important role in the oil chamber. When the piston rod 3 moves to the right due to external impact, the hydraulic oil in the oil chamber instantly passes through the throttling gap, generating a damping effect. This damping effect can effectively slow down the movement speed of the piston rod.

[0057] When the buffer is working, the impact head 1 is impacted, driving the piston rod 3 and the mandrel seat 6 to squeeze the hydraulic oil in the oil chamber to the right, forcing the oil chamber pressure to increase. The hydraulic oil pressure is collected by the pressure sensor 9 to obtain data, and the moving distance of the mandrel seat is obtained by the distance sensor 11. The squeezed hydraulic oil flows into the inner cavity of the piston rod 3 through the gap between the mandrel seat and the mandrel 7, pushing the isolation piston 5 in the inner cavity of the piston rod to compress the nitrogen chamber to the left. After the impact, the nitrogen chamber is restored, pushing the isolation piston to the right until it hits the mandrel, and the buffer returns to its original state.

[0058] When the buffer is not working, the pressure sensor measures whether the hydraulic oil level in the oil chamber changes and the distance sensor measures whether the original distance of the spindle seat changes to determine whether the buffer is in a fault state of oil leakage or air leakage. If a fault occurs, the transmission module 12 automatically alarms and provides location information, which is fed back to the monitoring platform to ensure that the management personnel can find it in time and take effective measures to ensure the normal operation of the lifting and transportation equipment.

[0059] In a specific embodiment, a flange 4 is provided on the outer surface of the outer sleeve.

The implementation of this system will significantly improve the performance and maintenance efficiency of the liquid-gas buffer in industrial applications.

[0079] Example 3

[0080] This embodiment describes a real-time monitoring method for a liquid-gas buffer based on a remote monitoring system, which analyzes the working status of the buffer through data collection, energy calculation, and efficiency evaluation. The following are specific implementation steps and data examples:

[0081] S1: Data collection;

[0082] S1.1: Acquisition of buffer force data: when the buffer is working, record the output value (P) of the pressure sensor in Pascal (Pa);

[0083] S1.2: Acquisition of buffer stroke data. During the period when the buffer is impacted, the initial and final positions of the spindle seat are recorded and the moving distance is calculated.

[0084] S2: Calculate the energy absorbed by the buffer;

[0085] S2.1: Calculate the buffer force;

[0086] Using the data from the pressure sensor, the cushioning force (F) is calculated based on the pressure of the hydraulic oil (P) and the effective cross-sectional area of ​​the oil chamber (A):

[0087] F=P×A

[0088] S2.2: The energy absorbed instantaneously (E) can be calculated using the following formula:

[0089] E=F×D

[0090] Where D is the distance the mandrel seat moves;

[0091] S2.3: Calculate the total energy absorbed (E 总 ) can be calculated by the following formula:

[0092] E 总 =E1+F2+…E n= = F1 × D1 + F2 × D2 + ... F n ×D n

[0093] Where E n It is the energy absorbed by the buffer instantly when the mandrel seat moves a distance D of n.

[0094] This method describes a remote monitoring solution for a liquid-gas buffer, which monitors the state of the buffer when it is not working, detects whether there is oil leakage and gas leakage, and feeds back the information to the monitoring platform in time to ensure the normal operation of the lifting and transportation equipment.

[0095] Step S1: Data collection

[0096] Oil level monitoring: When the buffer is not working, regularly collect the output value (P) of the pressure sensor and record the hydraulic oil level.

[0097] Distance monitoring: Regularly collect the measurement values ​​of the distance sensor and record the original distance of the spindle seat (D_initial).

[0098] Step S2: Fault diagnosis

[0099] Oil leakage judgment: When the hydraulic oil level drops significantly and the pressure measurement value (P) is lower than the preset threshold, it is judged that there may be an oil leakage.

[0100] By setting a monitoring cycle (such as every 1 hour), the current oil level is compared with the oil level in the previous cycle. If the oil level drops beyond the set value, an alarm is issued.

[0101] Leakage judgment: If the measured distance (D_current) of the mandrel seat changes (such as increases) compared with the original distance (D_initial), it is judged that there may be a leak.

[0102] Set the allowed distance change range. If it exceeds the range, an alarm will be issued.

[0103] Step S3: Data transmission and feedback

[0104] Fault information transmission: After detecting an oil or gas leak, the transmission module will feed back the fault information (including fault type, oil level change, distance change) and equipment location information (such as GPS coordinates) to the monitoring platform in real time.

[0105] Alarm and notification: After receiving fault information, the monitoring platform automatically generates alarm information and notifies management personnel via SMS, email, etc.

[0106] Step S4: Measures and responses

[0107] Fault handling: Based on the feedback information, managers assess the severity of the fault and take appropriate measures, such as arranging on-site inspection, maintenance or component replacement.

[0108] Recording and Analysis: Archive monitoring data and fault records to facilitate subsequent analysis and improvement of the monitoring system.

[0109] Through the above remote monitoring method, potential oil and gas leakage faults can be detected in time when the liquid-gas buffer is not working, ensuring the safe and reliable operation of the lifting and transportation equipment. The system's real-time data feedback and fault alarm mechanism provide effective support for managers, helping them to take quick measures and reduce equipment downtime.
