[0034] The arc-shaped inner side of the arc-shaped gate 7 is fixedly connected with a group of V-shaped gate arms 6, and the inner wall of the gate arm 6 is provided with a gate arm (not shown in the figure) for fixing the gate arm 6.
[0035] It should be noted that the positions and quantities of the hydraulic elements and the gate arms are matched.
[0036] As shown in the figure, Figure 2 The stroke measurement sensor is arranged outside the hydraulic element; the first support 8 is arranged on the hydraulic cylinder 2, the second support 10 is arranged on the hydraulic rod 3, and the first support 8 and the second support 10 are connected through the steel wire rope 9; the stroke measurement sensor is arranged on the first support 8, and the stroke of the hydraulic cylinder 2 is obtained by measuring the length of the steel wire rope 9.
[0037] As one or more embodiments, the deformation sensors are respectively arranged at the connection between the gate arm and the sub-arm, the connection between the gate plate and the gate arm, and the connection between the gate plate and the hydraulic rod.
[0038] As one or more embodiments, as shown in the figure, Figure 3 The monitoring mechanism includes a data acquisition card for receiving and modulating analog signals from each sensor of the gate, a programmable logic controller (PLC) for processing sensor data, and an industrial computer for analyzing and storing data; the signals output by the monitoring mechanism can be transmitted to the hydraulic elements of the double-hoisting-point opening and closing machine gate, and the stable operation of the hydraulic cylinder can be realized by precise control of the amount of hydraulic oil, the opening and closing actions and states of the double-hoisting-point arc-shaped gate can be effectively regulated and controlled, and the precision and safety of the operation of the entire water conservancy facility can be ensured.
[0039] The double-hoisting-point radial gate and its matching hydraulic hoist are comprehensively and carefully inspected to ensure that the equipment is not damaged and no foreign matter is stuck. High-precision displacement sensors, pressure sensors, and deformation sensors are installed at specified positions, and the sensors are ensured to be firmly installed and the measurement direction is correct. The electrical lines between the data acquisition card and each sensor and between the control and analysis system are connected, ensuring smooth signal transmission. Pay attention to the embedded installation of the sensors and the connection effect of the anti-interference circuit of the data acquisition card. The size of the double-hoisting-point radial gate (gate leaf width 8 m, height 5 m, arc radius 7 m), weight (10 tons), hydraulic system rated pressure (20 MPa), flow (50 L / min), motor power (30 kW), and rotational speed (1500 rpm) are input into the computer, as well as the expected test conditions, such as the gate opening speed set to 0.5 m / min, the gate closing speed set to 0.3 m / min, and the gate opening set to 0.5 m, 1 m, 2 m, 3 m, 4 m, etc.
[0040] No-load trial operation
[0041] Start the motor, set the hydraulic system pressure to 5 MPa, and the flow to 10 L / min. Make the piston rod perform full-stroke reciprocating motion at a low speed. Real-time data acquisition is performed through the monitoring mechanism. The industrial computer displays that the motor current fluctuates between 0-5 A, the voltage is stable at about 380 V, the hydraulic system oil inlet pressure changes between 4-6 MPa, and the piston rod displacement changes smoothly from 0-5 m. After analysis, the equipment runs smoothly without abnormal noise and vibration, and the no-load trial operation is normal.
[0042] Load test
[0043] Connect the piston rod hanger with the gate, and perform the gate opening and closing operation according to the preset test conditions. When the gate opening operation is performed to 1 m, the target speed is 0.5 m / min, and the actual speed calculated by the displacement sensor is 0.48 m / min, the deviation is within the allowable range. However, when the opening approaches 2 m, the actual speed drops to 0.45 m / min. The control and analysis system judges that the hydraulic system flow is slightly insufficient, and the PLC automatically adjusts the hydraulic pump displacement to restore the speed to the target value.
[0044] During the gate closing process, when the gate approaches the fully closed position, the pressure sensor detects that the hydraulic system pressure suddenly rises, and the control and analysis system judges that the gate is stuck, immediately stops the motor operation, and sends an alarm. Inspection finds that there is a small amount of debris accumulated at the bottom of the gate. After cleaning, the test continues.
[0045] After all the tests are completed, the collected data is analyzed. The opening and closing time of the gate at each opening degree basically meets the expectation, the running stability is good, the speed fluctuation range is within ±0.05 m / min. The positioning accuracy is within ±1 mm except for individual working conditions deviating by ±3 mm. The hydraulic system efficiency is between 70% and 80%, and the motor energy consumption is within a reasonable range.
[0046] In view of the problem that the positioning accuracy deviates greatly in individual cases, it is found through inspection that the installation support of the stroke measurement sensor of the hydraulic cylinder on the hydraulic rod is slightly loosened during the test. After being fixed again, the test is carried out again, and the positioning accuracy is significantly improved.
[0047] The above only describes preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
[0048] Although the specific embodiments of the utility model are described above in combination with the drawings, it is not a limitation on the protection scope of the utility model. Those skilled in the art should understand that various modifications or variations made on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
