Abstract
Description
Technical Field
[0001] The invention relates to a hydraulic damper, belonging to the field of vibration reduction, vibration resistance and electromechanical, and in particular to a hydraulic damper with a real-time performance monitoring function. Background Art
[0002] At present, hydraulic dampers are widely used in buildings, bridges, mechanical equipment, pipelines, etc. Dampers are generally used to achieve earthquake resistance and vibration reduction for external equipment (pipelines). For hydraulic dampers, once they are installed and put into service, it is usually impossible to know the performance status of the damper during operation. Only by regular testing of the damper performance through special testing equipment can the specific performance of the damper product be mastered. If the working oil leaks during the use of the damper, the damper loses its damping function, or the damper is stuck, etc., the damper will not work normally. Summary of the invention
[0003] To solve the above problems, the present invention proposes a hydraulic damper with a real-time performance monitoring function. Through the load sensing pin head, the load change of the damper is sensed in real time, and then the load signal of the load sensing pin head is collected by the signal acquisition and transmission equipment and transmitted remotely to the data processing center. The data processing center has pre-saved relevant information of the damper load test, including low-speed friction resistance, rated working load, locking load, locking load change rate and other related parameters. The hydraulic damper with a real-time performance monitoring function collects the relevant load data of the damper in real time, and compares it with the damper load test related information pre-saved by the data processing center in real time. Once the real-time load data of the damper deviates from the damper load test related information pre-saved by the data processing center, the data processing center will issue a warning reminder and require a performance test of the damper.
[0004] The technical solution of the present invention is as follows: A hydraulic damper with real-time performance monitoring function, comprising a data processing center, a hydraulic damper installation base, a left pin seat of the hydraulic damper, a load sensing pin head, a left pin shaft, a left pin head thread locking screw, a damper fixing part, a damper moving part, a right pin head thread locking screw, a right pin head, a right pin shaft, a right pin seat of the hydraulic damper and a signal acquisition and transmission device; The data processing center stores in advance the relevant information of the damper load test, including relevant parameters and curves such as low-speed friction resistance, rated working load, locking load and locking load change rate; the data processing center can analyze the received remote transmission signal and compare it with the pre-stored relevant data; and can issue a warning reminder for the damper with poor performance; The load sensing pin head is a pin head structure, wherein a load sensing part is arranged in the middle, and a load sensing line is arranged in the middle of the upper side, through which a working voltage is provided to the load sensing part, and through which a load signal of the load sensing part is transmitted to the outside; The left pin seat of the hydraulic damper can be reliably mounted on the hydraulic damper mounting base; The load sensing pin head is reliably connected to the connecting thread at the left end of the damper fixing part through a thread, and is reliably locked by a left pin head thread locking screw; The damper moving part is arranged at the right end of the damper fixing part; The right pin head is reliably connected to the connecting thread at the right end of the damper moving part through a thread, and is reliably locked by a right pin head thread locking screw; The right pin seat of the hydraulic damper forms a reliable connection with the external pipeline; The signal acquisition and transmission device is internally provided with a load sensing power supply, a data acquisition device and a data transmission device.

If the load signal obtained by the load sensing pin head is much larger than the low-speed friction resistance of the damper, the data processing center will issue a warning reminder, indicating that the damper is at risk of getting stuck and a timely inspection will be carried out; if the load signal obtained by the load sensing pin head is much smaller than the low-speed friction resistance of the damper, the data processing center will issue a warning reminder, indicating that the damper is at risk of oil leakage and a timely inspection will be carried out; When the external pipeline undergoes high-speed movement and impact, the relevant performance of the damper can be judged based on the locking load and the locking load change rate. If the locking load change rate of the load signal obtained by the load sensing pin head is much larger than the preset locking load change rate of the damper, the data processing center will issue a warning reminder, indicating that the damper is at risk of getting stuck, and timely detection will be carried out; if the locking load of the load signal obtained by the load sensing pin head is too small and the locking load change rate is much smaller than the preset locking load change rate of the damper, the data processing center will issue a warning reminder, indicating that the damper is at risk of oil leakage, and timely detection will be carried out.
