Description

Technical Field

[0001] This utility model relates to the field of hydraulic propulsion technology, specifically to a hydraulic propulsion position monitoring mechanism. Background Technology

[0002] An electro-hydraulic actuator is a propulsion system composed of an electric motor, gearbox, hydraulic cylinder, reducer, transmission mechanism, and control components. During operation, the kinetic energy input from the electric motor is transmitted to the drive shaft for rotation. The reducer then lowers the output speed, and the hydraulic cylinder converts the physical properties of the fluid into system pressure capable of transmitting the working force, thereby achieving motion control of the target object.

[0003] Currently, when assembling large-bore engines, hydraulic propulsion is often used for assembling hubs or shock absorbers to transfer large axial loads. Due to the structural limitations of the propeller, the propulsion status cannot be directly observed, which affects the consistency of the assembly process. Traditionally, the propulsion position monitoring of hydraulic propellers involves installing displacement sensors inside the propeller and monitoring the position in real time through an electronic control system. However, due to the influence of product processing differences and electronic control system errors, the starting position of the displacement sensor is different for each assembly, making it impossible to accurately locate the specific assembly position. Furthermore, the system is complex and costly. Therefore, a hydraulic propeller propulsion position monitoring mechanism is needed to improve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-4 The hydraulic thruster propulsion position monitoring mechanism shown includes a main body 1, and a monitoring component 2 is fixedly connected to the top of the main body 1;

[0026] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 3As shown, the main body 1 includes a base frame 101, and a bearing plate 104 is fixedly connected to the top of the base frame 101. The monitoring component 2 includes a top plate 201, and a hydraulic cylinder 202 is installed on the top of the top plate 201. A push rod 203 is fixedly connected to the output end of the hydraulic cylinder 202. A connecting plate 204 is fixedly connected to the bottom of the push rod 203. A connecting plate 205 is fixedly connected to the bottom of the connecting plate 204. A first mounting groove 206 is opened inside the top plate 201. A pulsed laser 207 is installed inside the first mounting groove 206. A second mounting groove 208 is opened inside the connecting plate 205. A reference object 209 is installed inside the second mounting groove 208. The pulsed laser 207 emits a laser pulse, which is reflected back after irradiating the reference object 209 and received by the photosensitive sensor inside the pulsed laser 207. By measuring the round-trip time of the laser pulse, the distance between the pulsed laser 207 and the reference object 209 can be obtained, and thus the distance of the push rod 203's push-out position can be obtained. The advantage of this method is that the measurement distance is long and the accuracy is high.

[0027] The top of the support plate 104 is fixedly connected to the support plate 213, the top of the support plate 213 is fixedly connected to the first sleeve 212, the inside of the first sleeve 212 is fixedly connected to the slide rod 211, the top of the slide rod 211 is slidably connected to the sliding sleeve 210, the sliding sleeve 210 is fixedly connected to the connecting plate 205, the bottom of the top plate 201 is fixedly connected to the second sleeve 214, the slide rod 211 extends into the inside of the second sleeve 214, there are four second sleeves 214, four first sleeves 212, four slide rods 211 and four sliding sleeves 210. The pulsed laser 207 can use the high directionality, high monochromaticity and high brightness of the laser to realize non-contact long-distance measurement, thereby increasing the efficiency of detecting the propulsion position of the hydraulic thruster, achieving the purpose of timely feedback, improving the accuracy of detection, and enabling real-time monitoring of the propulsion position of the hydraulic thruster.

[0028] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, a moisture-proof pad 102 is fixedly connected to the bottom of the base frame 101. There are four moisture-proof pads 102. An adjustment button 103 is fixedly connected to the side of the base frame 101. A support rod 105 is fixedly connected to the top of the support plate 104. A control box 106 is fixedly connected to the top of the support rod 105. A display screen 107 is fixedly connected to the side of the control box 106. Several physical buttons 108 are provided on the side of the control box 106. The function of the moisture-proof pad 102 is to isolate the heat exchange between the equipment and the ground to achieve the purpose of moisture prevention.

[0029] In this solution, a hydraulic thruster position monitoring mechanism uses an adjustment button 103 to control the start of the hydraulic cylinder 202, which in turn drives the thrust rod 203 to extend and retract. The extension and retraction of the thrust rod 203 can move the connecting plate 204 and the connecting plate 205. Since the sliding sleeve 210 slides on the sliding rod 211 and the connecting plate 205 is fixedly connected to the sliding sleeve 210, the change in the extension and retraction position of the thrust rod 203 will also cause the positions of the reference object 209 and the pulsed laser 207 to change synchronously. During monitoring, the pulsed laser 207 emits laser pulses, which are reflected back after illuminating the reference object 209 and are received by the photosensitive sensor inside the pulsed laser 207. By measuring the round-trip time of the laser pulse, the distance between the pulsed laser 207 and the reference object 209 can be obtained, and thus the distance of the thrust rod 203's extension position can be determined. The extension and retraction of the thrust rod 203 can change the distance between the pulsed laser 207 and the reference object 209, thereby enabling real-time monitoring of the position change of the thrust rod 203.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
