Technical Field
[0001] This utility model relates to the field of intelligent hydraulic station vibration reduction technology, specifically an intelligent hydraulic station vibration reduction device. Background Technology
[0002] Intelligent hydraulic power units are hydraulic power source devices or hydraulic devices including control valves, consisting of hydraulic pumps, drive motors, oil tanks, directional valves, throttle valves, and relief valves. Existing intelligent hydraulic power units generate vibrations during operation, requiring the use of vibration damping devices for vibration reduction.
[0003] Intelligent hydraulic power unit vibration damping devices typically consist of several main components, including sensors, control units, actuators, and a hydraulic system. Their working principle is as follows: Sensors: Intelligent hydraulic power unit vibration damping devices are usually equipped with acceleration sensors or other types of sensors to monitor the vibration of the machine or equipment in real time. Actuators: When the control unit determines that vibration damping is needed, it sends a signal to control the actuator's action. The actuator usually consists of a hydraulic cylinder or other types of actuators used to adjust the vibration of the machine or equipment. Hydraulic System: The hydraulic system is responsible for providing the necessary hydraulic energy to ensure that the actuator can effectively complete the vibration damping operation. The hydraulic system typically consists of a hydraulic pump, oil tank, valves, etc. During operation, the sensors monitor vibration in real time and transmit data to the control unit; the control unit analyzes the data and determines whether vibration damping is needed; if damping is required, it controls the actuator to adjust the hydraulic system according to a preset algorithm, thereby achieving the vibration damping effect. In this way, intelligent hydraulic power unit vibration damping devices can effectively reduce the damage and impact of vibration on equipment, improving the stability and safety of the equipment.
[0004] Existing vibration damping devices typically rely on a single structure for vibration damping in intelligent hydraulic power units, resulting in poor damping performance. Therefore, a vibration damping device for intelligent hydraulic power units is proposed to address this issue. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes an intelligent hydraulic station vibration reduction device.
[0006] The technical solution adopted by this utility model to solve its technical problem is an intelligent hydraulic station vibration damping device, including a base, a plate groove inside the base, a buffer plate assembled in the plate groove, a fixing plate installed on the buffer plate, an oil tank installed on the fixing plate, multiple sets of springs installed on the inner wall of the plate groove, the other end of the springs connected to the buffer plate, multiple sets of dampers installed between the plate groove and the buffer plate, the damper including a first ball joint seat, the first ball joint seat is fixedly installed on the inner wall of the plate groove, and a damping cylinder is installed on the first ball joint seat. The cylinder has an internal groove, in which a piston block is fitted. A damping rod is mounted on the piston block, and a second ball joint is mounted on the damping rod. The other end of the second ball joint is fixedly connected to the side wall of the buffer plate. Two airbags are installed between the buffer plate and the base. When the buffer plate vibrates, the air pressure resistance of the airbags can absorb the impact force and reduce vibration. This structure uses the elastic deformation of the spring, the frictional resistance of the damper, and the air pressure resistance of the airbags to dampen the intelligent hydraulic station, avoiding the poor damping effect of a single structure and improving the damping effect.
[0007] Preferably, springs are installed on all six sides of the buffer plate, and the springs are sleeved around the damper. A drive motor is mounted on the oil tank via a base. An oil pump is mounted on the output shaft of the drive motor and is fixedly mounted on the oil tank. A first oil pipe is installed at one end of the oil pump, and the other end of the first oil pipe is connected to the oil tank. A second oil pipe is connected to the other end of the oil pump, and the other end of the second oil pipe is connected to a high-power air cooler. A third oil pipe is installed on the high-power air cooler, and a pressure gauge is installed on the third oil pipe. A solenoid valve is connected to the other end of the third oil pipe. The system is fixedly installed on an oil tank, which has a filler port and a level gauge on its side wall. When the intelligent hydraulic station operates, it generates vibrations. The overall vibration of the intelligent hydraulic station causes the oil tank to vibrate, which in turn causes the fixed plate to vibrate. The fixed plate then causes the buffer plate to vibrate within a groove in the base. The spring between the buffer plate and the groove undergoes elastic deformation, absorbing impact and storing energy. Simultaneously, the piston block slides in the groove of the damping cylinder, generating frictional resistance. This frictional resistance reduces impact and vibration, preventing excessive vibration and noise pollution, thus contributing to noise reduction.
[0008] The advantages of this utility model are:
[0009] 1. This utility model utilizes the air pressure resistance of the airbag to absorb impact and reduce vibration when the buffer plate vibrates. This structure uses the elastic deformation of the spring, the frictional resistance of the damper, and the air pressure resistance of the airbag to reduce vibration of the intelligent hydraulic station, avoiding the poor vibration reduction effect of a single structure and improving the vibration reduction effect.
[0010] 2. This utility model utilizes the vibration generated by the intelligent hydraulic station during operation. The overall vibration of the intelligent hydraulic station causes the oil tank to vibrate, which in turn causes the fixed plate to vibrate. The fixed plate then causes the buffer plate to vibrate. The buffer plate vibrates within the groove of the base, causing the spring between the buffer plate and the groove to undergo elastic deformation. The spring can absorb impact force and store energy. At the same time, the piston block slides in the groove of the damping cylinder, generating frictional resistance. This frictional resistance can reduce impact force and vibration, preventing excessive vibration from causing noise pollution, thus helping to reduce noise pollution. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Please see Figure 1-5 As shown, an intelligent hydraulic station vibration damping device includes a base 1, a groove 2 inside the base 1, a buffer plate 3 inside the groove 2, a fixing plate 4 on the buffer plate 3, an oil tank 5 on the fixing plate 4, multiple sets of springs 6 on the inner wall of the groove 2, the other end of the springs 6 connected to the buffer plate 3, and multiple sets of dampers between the groove 2 and the buffer plate 3. Each damper includes a first ball joint seat 7, which is fixedly installed on the inner wall of the groove 2. A damping cylinder 8 is installed on the first ball joint seat 7, a sliding groove 9 inside the damping cylinder 8, a piston block 10 inside the sliding groove 9, a damping rod 11 on the piston block 10, and a second ball joint seat 12 on the damping rod 11. The other end of the second ball joint seat 12 is fixedly connected to the side wall of the buffer plate 3. Two airbags 13 are installed between the buffer plate 3 and the base 1. Springs 6 are installed on all six sides of the buffer plate 3, and the springs 6 are sleeved around the damper. A drive motor 14 is mounted on the oil tank 5 via a base. An oil pump 15 is mounted on the output shaft of the drive motor 14 and is fixedly mounted on the oil tank 5. A first oil pipe 16 is installed at one end of the oil pump 15, and the other end of the first oil pipe 16 is connected to the oil tank 5. A second oil pipe 17 is connected to the other end of the oil pump 15, and a high-power air cooler 18 is connected to the other end of the second oil pipe 17. A third oil pipe 19 is installed on the high-power air cooler 18, and a pressure gauge 20 is installed on the third oil pipe 19. A solenoid valve 21 is connected to the other end of the third oil pipe 19 and is fixedly mounted on the oil tank 5. The oil tank 5 is equipped with an oil filler port 22, and a level gauge 23 is installed on the side wall of the oil tank 5. During operation, existing shock absorption devices typically rely on a single structure for vibration damping in intelligent hydraulic stations, resulting in poor damping performance. In contrast, when the intelligent hydraulic station is in use, the drive motor 14 rotates the oil pump 15, which draws oil from the oil tank 5 and pumps it out, converting mechanical energy into hydraulic oil pressure energy. The hydraulic oil, after being regulated in direction, pressure, and flow by the solenoid valve 21, is transmitted to the cylinders or motors of hydraulic machinery via external pipelines. This controls the direction, force, and speed of the hydraulic actuator, driving various hydraulic machines to perform work. The intelligent hydraulic system... When the intelligent hydraulic station is in operation, it will generate vibration. The entire intelligent hydraulic station vibrates, which in turn causes the oil tank 5 to vibrate. The oil tank 5 causes the fixed plate 4 to vibrate, which in turn causes the buffer plate 3 to vibrate. The buffer plate 3 vibrates within the groove 2 of the base 1. The spring 6 between the buffer plate 3 and the groove 2 undergoes elastic deformation. The spring 6 can absorb the impact force and store energy. At the same time, the piston block 10 slides in the groove 9 of the damping cylinder 8, generating frictional resistance. The frictional resistance can reduce the impact force and vibration. This structure absorbs the impact force and reduces the vibration through the elastic deformation of the spring 6 and the frictional resistance of the damper, thus avoiding large vibrations during the use of the intelligent hydraulic station, preventing long-term vibration from damaging the internal mechanical components of the intelligent hydraulic station, and avoiding excessive vibration from causing noise pollution.
[0020] By installing two airbags 13 between the buffer plate 3 and the base 1, the two airbags 13 are located around the buffer plate 3 and at the top and bottom ends of the buffer plate 3. When the buffer plate 3 vibrates, the air pressure resistance of the airbags 13 can absorb the impact force and reduce the vibration. This structure uses the elastic deformation of the spring 6, the frictional resistance of the damper and the air pressure resistance of the airbags 13 to reduce the vibration of the intelligent hydraulic station, avoiding the poor vibration reduction effect of a single structure and improving the vibration reduction effect.
[0021] Working principle: Existing shock absorption devices typically rely on a single structure for vibration damping in intelligent hydraulic stations, resulting in poor damping performance. In contrast, when the intelligent hydraulic station is in use, the drive motor 14 rotates the oil pump 15, which draws oil from the oil tank 5 and pumps it out, converting mechanical energy into hydraulic oil pressure energy. The hydraulic oil, after being regulated in direction, pressure, and flow by the solenoid valve 21, is transmitted to the cylinders or motors of the hydraulic machinery via external pipelines. This controls the direction, force, and speed of the hydraulic actuator, driving various hydraulic machines to perform work. The intelligent hydraulic station vibrates during operation, causing the oil tank 5 to vibrate, which in turn causes the fixed plate 4 to vibrate, which in turn causes the buffer plate 3 to vibrate. The buffer plate 3 vibrates within the groove 2 of the base 1, causing the spring 6 between the buffer plate 3 and the groove 2 to elastically deform. The spring 6 absorbs impact and stores energy, while the piston block 10 slides in the groove 9 of the damping cylinder 8, generating frictional resistance. This frictional resistance reduces impact and vibration. This structure absorbs impact and reduces vibration through the elastic deformation of the spring 6 and the frictional resistance of the damper, preventing large vibrations in the intelligent hydraulic station during use, avoiding damage to the internal mechanical components of the intelligent hydraulic station from prolonged vibration, and preventing excessive vibration from causing noise pollution. Two airbags 13 are installed between the buffer plate 3 and the base 1. The two airbags 13 are located around the buffer plate 3 and at the top and bottom ends of the buffer plate 3. When the buffer plate 3 vibrates, the air pressure resistance of the airbags 13 can absorb impact and reduce vibration. This structure uses the elastic deformation of the spring 6, the frictional resistance of the damper, and the air pressure resistance of the airbags 13 to dampen the intelligent hydraulic station, avoiding the poor damping effect of a single structure and improving the damping effect.
