Description

Technical Field

[0002] In water conservancy projects, lifting and horizontal steel gates play a vital role. They are not only the controllers of water flow, but also the key to water level regulation and downstream safety protection. They are widely used in various water conservancy projects, and the matching locking and releasing devices (gate holders) are usually placed above the gate slots and distributed symmetrically on both sides of the gates to ensure the stable operation of the gates. However, the traditional automatic locking and releasing principle of the gate holder mainly relies on gravity. This design requires that the gate and the gate holder must be within a certain distance range in use to achieve correct movement. This also means that there is a risk of collision between the main wheel and the diagonal support plate, which may not only affect the smooth operation of the gate, but also cause a major accident in which the gate hoist is seriously damaged. In addition, the locking / releasing process of the gate holder is a dynamic and complex process involving multiple factors. For gates that are opened and closed with multiple lifting points, the asynchronous travel may even cause unilateral decoupling, and both the soft connection of the wire rope and the hard connection of the hydraulic rod will be affected to varying degrees.

[0022] To make the objectives, technical solutions and advantages of this application clearer, the implementation manners of this application will be further described in detail below with reference to the accompanying drawings.

[0023] The technical solutions of this application and how the technical solutions of this application solve the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0024] As Figure 1 shown is a flowchart of an analysis and adjustment method for a gate restrainer applied to a gate. The method includes the following steps: obtaining and recording the angle θ of the gate restrainer when the gate runs to push open the support body through an angle sensor arranged in a coupling manner on the active gear 1 var , the angle θ when the gate restrainer is locked when the gate is normally placed lock , and the critical angle θ of the gate restrainer when the gate is released lose , where the direction vertically downward to the ground is used as the 0° reference angle, and a clockwise rotation of one circle is recorded as 0° to 360°, θ var < θ lose < θ lock ;

[0025] In this embodiment, the angle θ of the gate restrainer when the gate runs to push open the support body var is the angle of the gate restrainer when the gate runs to push open the support body, that is, during the process of starting to open or close the gate, when the gate restrainer contacts the support body and begins to change its position. This angle is dynamically changing because it depends on the actual movement of the gate; the angle θ when the gate restrainer is locked when the gate is normally placed lockRefers to the angle of the door stopper when the gate is normally placed (i.e., the gate is in a fully open or closed state and the door stopper has locked the position of the gate). This angle indicates that the door stopper has successfully fixed the gate in a specific position, ensuring the stability and safety of the system. The critical angle θ of the door stopper when releasing the gate lose Refers to a critical angle reached by the door stopper when the gate is released (e.g., from a locked state to a free state, allowing the gate to move freely under gravity or other external forces). At this angle, the door stopper may no longer be able to effectively support or control the position of the gate, and the gate may start to fall or move freely. Therefore, θ lose Is a very important safety parameter that needs to be accurately measured and monitored. θ var <θ lose <θ lock This means that when the gate starts to push open the support body, the angle of the door stopper is the smallest; as the gate continues to move, the angle of the door stopper will gradually increase until it reaches the critical angle θ lose ; if the gate is locked, the angle of the door stopper will further increase to θ lock . Additionally, an angle sensor is installed on the driving gear 1 to ensure that the sensor can accurately measure the change in the angle of the door stopper.

[0026] Additionally, θ lock The value determines that the angle of at least 10 normal door placement states needs to be sampled and the calibration value is calculated using the representative value method. Where Is the average value of the angles of 10 normal gates reaching the upper limit placement state, ta is the calibration coefficient, and the allowable error rate here is 5%: then ta = 0.05, S is the mean square deviation of 10 normal samples: m is the cumulative number of times: m = 10, and finally the calibration value θ lock .

[0027] According to the number of gears, the rotational speed of the driving gear 1, and the gear rotational speed formula, calculate the rotational speed of the driven gear 2. Based on the rotational speed of the driven gear 2 and the real-time angle θ of the door stopper before adjustment rt Obtain the initial adjustment time T of the synchronous motor angle 调 , and based on the initial adjustment time T of the synchronous motor angle 调 Electrically lift the gate to achieve the initial angle adjustment of the door stopper;

[0028] In this embodiment, a driven gear 2 driven by a synchronous motor is additionally installed at the driving gear 1. If the number of gears of the driving gear 1 is Z 1 , the rotational speed is n 1 , and the number of gears of the driven gear 2 is Z 2 , the rotational speed is n2 , according to the gear speed formula , the rotational speed of the driven gear 2 can be obtained At this time, if the real-time door restrainer angle before adjustment is θ rt , and the angle θ when the door restrainer is locked during normal shelving lock , the angle difference is θ rt - θ lock , where the positive and negative represent the forward and reverse rotation directions of the synchronous motor, and the preliminary synchronous motor angle adjustment time is obtained as:

[0029] Based on the initial adjustment time T of the synchronous motor angle 调 , electrically lifting the gate to achieve the preliminary angle adjustment of the door restrainer includes: if T 调 ≤1s, the gate is lifted electrically through the relay, and the relay closing time at this time is T 调 ; if T 调 >1s, the gate is lifted electrically through the relay, and the relay closing time at this time is T 调 + T 吸合延时 , where T 吸合延时 is the sum of the contactor closing delay in the main circuit for the gate to rise and the intermediate relay closing delay in the control circuit. Among them, the contactor closing delay and the intermediate relay closing delay are obtained from the nameplates of the contactor and the intermediate relay respectively.

[0030] Specifically, if T 调 is less than or equal to 1 second, then the relay will be commanded to perform the lifting operation, and its closing time will be set to T 调 , which means the relay will remain closed for a time of T 调 . When T 调 is greater than 1 second, the relay also performs the lifting electric action, but its closing time is no longer T 调 , but T 调 plus an additional closing delay T 吸合延时 . This T 吸合延时 is obtained by adding the contactor closing delay in the main circuit for the gate to rise and the intermediate relay closing delay in the control circuit. The purpose of this is to ensure that in a longer adjustment time, the relevant electrical components have enough time to start and work. This process ensures the precise control of the gate, especially in cases where quick response or longer operation time is required.

[0031] Calculate the number of pulses P required to drive the synchronous motor to adjust the door restrainer 1 , and perform a secondary angle adjustment on the door restrainer based on the number of pulses P 1 ;

[0032] In this embodiment, if the stepping angle of the synchronous motor is θ 步 , then the number of pulses required to drive the synchronous motor one revolution is: The number of pulses required to drive the synchronous motor to adjust the door stopper is: Based on the number of pulses P 1 , use the synchronous motor driver to drive the synchronous motor to perform a secondary angle adjustment on the door stopper.

[0033] This means that to drive the synchronous motor to adjust the angle of the door stopper, it is necessary to know the angle θ of the door stopper when the supporting body is pushed open var and the angle θ when the door stopper is locked lock , and then calculate the number of pulses P required to drive the motor based on the difference between these two angles and the stepping angle of the synchronous motor 1 . Once P is calculated 1 , use the synchronous motor driver to send pulses with the corresponding number of pulses P 1 to the motor, thereby driving the door stopper to perform an angle adjustment.

[0034] After the secondary angle adjustment, determine whether the deviation value between the adjusted angle of the door stopper and the normal locking angle meets the preset condition. If not, further adjustment is performed until the angle deviation value meets the preset condition.

[0035] In this embodiment, after the secondary angle adjustment, determining whether the deviation value between the adjusted angle of the door stopper and the normal locking angle meets the preset condition, and if not, further adjusting until the angle deviation value meets the preset condition includes: determining the adjusted angle θ of the door stopper rt2 and the angle θ when normally locked lock of the angle difference |θ rt2 - θ lock | is less than or equal to 1°. If it is less than or equal to 1°, the door stopper locking angle requirement is met, and the angle adjustment ends; if not, further determine the angle difference |θ between the left door stopper angle θ lf and the right door stopper angle θ rg . If |θ lf - θ rg |, if |θ lf - θ rg | > 2°, and |θ lf - θ lock | ≥ |θ rg - θ lock |, then fine-tune the left door stopper. If |θ lf - θ rg | > 2°, and |θ lf - θ lock | < |θ rg - θ lock|, then fine-tune the right door shelf, and repeat the adjustment cycle until |θ is satisfied. rt2 -θ lock |End adjustment when ≤1°.

[0036] Specifically, first, the adjusted door shelf angle θ is compared. rt2 Angle θ with normal locking lock , see if the absolute angle difference between them is less than or equal to 1°. If it is less than or equal to 1°, it is considered that the requirement is met and the adjustment is completed; otherwise, proceed to the next step.

[0037] If the first step is not satisfied, calculate the left door shelf angle θ lf and the right door shelf angle θ rg If the difference is greater than 2° and the angle deviation of the left door shelf is greater than or equal to that of the right door shelf, then fine-tune the left door shelf; conversely, if the deviation on the right is greater, adjust the right door shelf. The basis for fine-tuning is the pulse number P 2 , which is proportional to the angle difference and to the step angle θ 步 Inversely proportional to the square of .

[0038] Specifically, the fine adjustment of the left door holder and the fine adjustment of the right door holder are both based on the pulse number P 2 When the left door shelf is fine-tuned, the When fine-tuning the right door shelf, This process will continue until the adjusted angle deviation meets the preset condition of 1°. Please note that the step angle θ 步 It refers to the angle corresponding to each step of the door motor movement, and P 2 represents the number of synchronous motor pulses required to achieve fine adjustment. This is an iterative process aimed at precisely adjusting the angle of the door.

[0039] This embodiment is a method for analyzing and adjusting the door holder, which monitors the angle value in real time, calculates the angle deviation value, controls the clutch and the stepper motor to adjust the angle, and then controls the automatic movement of the door holder, realizes intelligent control of the movement of the door holder, accurately locates the normal locking and release angles, and ensures the normal operation of the door holder. Through this transformation, the jamming and locking failures of the door holder and the roller can be effectively avoided, thereby preventing the gate from being unable to operate, equipment damage and economic losses. By analyzing and providing angle adjustment information for situations such as left and right tilting of the extending and horizontal gate after reaching the upper limit, abnormal gate posture, etc., it can also greatly reduce the occurrence of problems such as jamming and blocking of the extending gate, and can also be interconnected with information such as gate position meter, gate posture, and gate action status.
