Description

Technical Field

[0001] The utility model relates to the field of hydraulic control devices, in particular to a servo hydraulic control device. Background Art

[0002] The servo hydraulic control device is an electromechanical system that uses hydraulic principles for precise control. The system is driven by hydraulic power elements and ensures that output quantities such as displacement, speed, and force can accurately and quickly follow changes in input signals through a feedback control mechanism. In this process, the hydraulic pump converts mechanical energy into hydraulic energy to provide the required power for the system. The control valve, as the core component, finely adjusts the hydraulic flow and pressure according to the real-time signal of the sensor and the preset control parameters to control the output of the fluid, thereby achieving precise control of the controlled object. The hydraulic fluid eventually enters the hydraulic cylinder and generates the required linear displacement or force through the movement of the piston, thereby driving the target device to reach the preset position, speed or force state.

[0003] In order to prevent overheating due to the accumulation of liquid impurities, existing servo hydraulic control devices usually install temperature sensors at key locations such as the liquid inlet and outlet and the motor. However, although this decentralized temperature monitoring method can reflect the temperature conditions of each location to a certain extent, it has limitations because it can only monitor the temperature of each independent location and cannot provide a comprehensive and systematic thermal status analysis. When the servo hydraulic control device overheats, this decentralized monitoring method makes it difficult for maintenance personnel to quickly and accurately locate the specific cause of the overheating, thereby affecting the efficiency of troubleshooting and the timely recovery of the device. Therefore, a more comprehensive and efficient servo hydraulic control device is needed to solve this problem. Utility Model Content

The universal ball seat 308 is slidably connected to another slide groove 303. The adjusting rod 307 is used to adjust the universal ball seat 308 so that the mounting seat 304 can be clamped with the annular slide rail 302; the top of the adjustment seat 309 is rotatably connected to a visual monitoring device 310 through a damping shaft. The visual monitoring device 310 is used to detect the local temperature of the control device 2 and is stably placed in the required position through the mounting mechanism 1. The control device 2 is responsible for accurately controlling the external liquid cylinder. The setting of the monitoring mechanism 3 is very unique. It enables the monitoring device to rotate 360 ​​degrees around the control device through the fixed frame 301 and the annular slide rail 302. The advantage of this structure is that it can monitor the temperature status of the control device comprehensively and without blind spots, timely discover potential thermal failure risks, and improve the safety and reliability of the equipment.

[0034] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The motor 305 is used to drive the driving wheel 306 to rotate. After the driving wheel 306 rotates, it can cooperate with the universal ball of the universal ball seat 308 to make the mounting seat 304 slide on the annular slide rail 302, so that the mounting seat 304 slides smoothly on the annular slide rail 302. The advantage of this setting is that it realizes an automated movement method, improves monitoring efficiency, and ensures that every part of the control device can be monitored evenly and accurately, greatly improving the reliability and comprehensiveness of the temperature data.

The advantages of aluminum alloy are that it is light and corrosion-resistant, which not only reduces the weight of the entire device, but also extends the service life of the equipment, while also helping to improve the mobility and stability of the monitoring equipment.

[0039] The implementation principle of the present invention is as follows: first, the servo hydraulic control device is firmly placed in the predetermined position through the base 101 of the mounting mechanism 1, and the control device 2 is ensured to be correctly installed on the mounting platform 104, and all necessary hydraulic lines are connected, and the various components of the monitoring mechanism 3, including the fixing frame 301, the annular slide rail 302, the mounting base 304, etc., are checked to ensure that they are all correctly installed and can work normally;

[0040] Ensure that the visual monitoring device 310 is correctly installed on the steering seat 309 and adjust the angle so that it can clearly monitor all parts of the control device 2. Start the control device 2 and start controlling the external hydraulic cylinder to perform hydraulic operations. At the same time, the monitoring mechanism 3 is periodically started through the external controller, especially the motor 305, which drives the driving wheel 306 to rotate. In conjunction with the universal ball of the universal ball seat 308, the mounting seat 304 slides smoothly on the annular slide rail 302. The visual monitoring device 310 begins to capture and record the local temperature data of the control device 2 in real time.

[0041] The monitoring mechanism 3 can achieve 360-degree rotation through the setting of the annular slide rail 302 and the mounting seat 304, thereby comprehensively monitoring the temperature status of the control device 2. If the local temperature is found to be too high or abnormal, the visual monitoring device 310 will record it in real time and issue an alarm. Subsequently, the operator can quickly locate the specific cause of overheating based on the data provided by the visual monitoring device 310, such as blockage of the hydraulic pipeline, internal failure of the control device, etc.
