Description

Technical Field

[0001] This invention relates to the field of hoisting equipment and nuclear power plant construction technology, and in particular to an automatic hoisting control system for a new fuel container in a nuclear island. Background Technology

[0002] During the construction of a nuclear power plant, new fuel rods need to be transported into the nuclear island fuel storage area. The transport and hoisting of the new fuel containers requires the use of a 550t circular crane with lifting and translation mechanisms. This hoisting is not a simple vertical lift; the entire process involves a curved path. Previously, hoisting the new fuel containers required close cooperation between operators, crane operators, and monitoring personnel at various locations. This method is susceptible to human factors (participants' skill levels, psychological factors, teamwork, risk analysis and control capabilities, emergency response capabilities, physical condition, etc.) which directly affect the safety and accuracy of the hoisting, and is also inefficient. Therefore, an automated lifting control method is proposed for this purpose.

[0003] Existing technologies, such as patent CN214298950U (automatic lifting control device and automatic lifting device), use simple circuit control to reduce manual operation and complete simple vertical lifting and hoisting tasks; however, they cannot meet the actual needs of curved transfer and dual-mechanism automatic hoisting tasks. Patent CN118561170B (a crane hoisting angle detection device) is used for angle detection through a mechanical structure during vertical hoisting. Single angle detection cannot meet the actual needs of curved transfer tasks during hoisting, and this device cannot be installed on the new fuel container of the nuclear island. Patent CN108249307B (a mobile measurement and feedback control system and method for a large crane) requires a mobile external scanning analyzer and a networked GPS-assisted new fuel container of the nuclear island, which cannot meet the conditions of a closed space without signal within the nuclear island or the inability to add other mobile new fuel containers in a confined space.

[0004] Therefore, a hoisting control system is needed that is suitable for the curved transfer and automatic hoisting of new fuel containers in nuclear islands, and meets the requirements of high safety factor and high precision in high radiation environment. Summary of the Invention

[0005] In view of this, the present invention provides an automatic hoisting control system for new fuel containers in nuclear islands, which solves the problems of limited hoisting space, high risk of human error, and long hoisting time. Under the premise of ensuring the original shape of the new fuel containers in nuclear islands, the system completes the curved operation and automatic hoisting of the new fuel containers in nuclear islands through the logical operation of the hoisting mechanism.

[0006] Therefore, the present invention provides the following technical solution:

[0007] An automated hoisting control system for a new fuel container in a nuclear island includes:

[0008] The hoisting device, support frame, and control system; the hoisting device includes a translation mechanism and a lifting mechanism.

[0009] During the hoisting process, one end of the new fuel container for the nuclear island is fixed to the support, and the other end is connected to the hoisting device via a hoisting rope;

[0010] The lifting weight of the new fuel container for the nuclear island is obtained through the weighing system of the lifting device; the horizontal displacement distance of the translation mechanism is obtained through the horizontal position encoder of the lifting device; the vertical displacement distance of the lifting mechanism is obtained through the lifting position encoder; and the length of the lifting rope is obtained through the drum encoder.

[0011] The lifting weight, vertical displacement distance, horizontal displacement distance, and lifting rope length are transmitted to the control system via a bus.

[0012] The control system uses the hoisting weight, vertical displacement distance, horizontal displacement distance, and hoisting rope length to obtain the hoisting angle and tilt deviation; and adjusts the translation speed of the translation mechanism and the lifting speed of the lifting mechanism based on the hoisting angle, tilt deviation, and hoisting weight to control the tilt deviation of the new fuel container in the nuclear island within a safe range.

[0013] Furthermore, the weighing system is installed at the lower end of the fixed pulley balance arm of the hoisting device;

[0014] The translation mechanism is a trolley;

[0015] The horizontal position encoder is installed at the concentric axle position of the trolley wheel;

[0016] The lifting position encoder is installed at the concentric position of the lifting drum.

[0017] Furthermore, the control system utilizes the hoisting weight, vertical displacement distance, horizontal displacement distance, and hoisting rope length to obtain the hoisting angle and tilt deviation, including:

[0018] Constructing the trajectory equation for the hoisting of the new fuel container on the nuclear island:

[0019] =R-Rcosθ

[0020] Y=Rsinθ

[0021] In the formula, Y represents the displacement of the translation mechanism from its initial position to its final position; R represents the displacement of the lifting mechanism from its initial position to its final position; θ represents the rotation radius of the new fuel container on the nuclear island; and θ represents the hoisting angle.

[0022] The following speed of the trolley is obtained based on the trajectory equation for the hoisting of the new fuel container on the nuclear island:

[0023] =0.5·tan(sin -1 ( ))

[0024] In the formula, The speed of the lifting mechanism during hoisting is t, and the running time is t.

[0025] The lifting and following speed is obtained based on the hoisting trajectory equation of the new fuel container on the nuclear island:

[0026] =

[0027] In the formula, t represents the speed of the translation mechanism during hoisting, and t represents the running time.

[0028] The hoisting angle is obtained based on the hoisting trajectory equation of the new fuel container for the nuclear island.

[0029] θ=

[0030] Based on the real-time length of the lifting rope And the position of the translation mechanism is perpendicular to the length of the running trajectory. The relationship between them, the tilt angle deviation includes positive tilt angle deviation and negative tilt angle deviation;

[0031] when This is a positive tilt angle deviation;

[0032] when This indicates a negative tilt angle;

[0033] The position of the translation mechanism is perpendicular to the length of the running trajectory. :

[0034]

[0035] In the formula, H represents the maximum stroke of the lifting mechanism.

[0036] Furthermore, the method of controlling the tilt angle of the new fuel container in the nuclear island within a safe range by adjusting the translation speed of the translation mechanism and the lifting speed of the lifting mechanism based on the hoisting angle, tilt angle deviation, and hoisting weight includes:

[0037] During the hoisting process, first determine whether the hoisting angle is within the safe range. If it is, then determine whether the hoisting weight is within the safe weight range.

[0038] If the lifting weight is within the safe weight range, the lifting of the new fuel container for the nuclear island is complete;

[0039] If the lifting weight is not within the safe weight range, the lifting mechanism will operate at the lifting following speed, and the translation mechanism will operate at the trolley following speed; and the lifting weight will be checked again to see if it is within the safe weight range.

[0040] Furthermore, the determination of whether the hoisting angle is within the safe range also includes:

[0041] If not, the lifting mechanism operates at its maximum operating speed, and the translation mechanism operates at the trolley following speed; the operating speeds of the lifting mechanism and translation mechanism are adjusted according to the tilt angle deviation to ensure that the tilt angle deviation is always less than the maximum allowable angle of vertical hoisting rope offset, until the new fuel container of the nuclear island is hoisted.

[0042] Furthermore, the adjustment of the operating speed of the lifting mechanism and the operating speed of the translation mechanism based on the tilt angle includes:

[0043] When the tilt angle is within the normal range, the lifting mechanism operates at the lifting and following speed, and the translation mechanism operates at the trolley following speed; and then it is determined again whether the hoisting angle is within the safe range.

[0044] If the tilt angle is within the fault range, the hoisting of the new fuel container for the nuclear island shall be stopped.

[0045] When the tilt angle deviation is within the positive abnormal range, the lifting mechanism operates at a positive compensation lifting and following speed, and the translation mechanism operates at a negative compensation trolley following speed; and then it is determined again whether the tilt angle deviation is within the normal range.

[0046] When the tilt angle deviation is within the negative abnormal range, the lifting mechanism operates at a negative compensation lifting and following speed, and the translation mechanism operates at a positive compensation trolley following speed; and then it is determined again whether the tilt angle deviation is within the normal range.

[0047] Advantages and positive effects of the present invention:

[0048] This invention constructs a trajectory equation for the hoisting of the new nuclear island fuel container; calculates the trolley following speed, lifting following speed, hoisting angle, and tilt skew; and adjusts the operating speed of the translation mechanism and the lifting mechanism in real time based on the hoisting angle, hoisting weight, and tilt skew, thereby achieving automatic adjustment of the hoisting of the new nuclear island fuel container, eliminating the swaying of the new nuclear island fuel container during the hoisting process, and ensuring the safety and accuracy requirements of the hoisting of the new nuclear island fuel container.

[0049] The method of this invention reduces safety hazards caused by human risk factors and improves work efficiency; it also eliminates the need for secondary processing and modification of the new fuel container for the nuclear island, enabling the hoisting of the new fuel container for the nuclear island in a limited space; thus solving the problem that the existing technology is limited to vertical hoisting and cannot achieve special model curved motion hoisting.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0057] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or new nuclear island fuel container that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or new nuclear island fuel containers.

[0058] This invention provides an automatic hoisting control system for new fuel containers in nuclear islands. It collects parameters of the new fuel containers, including their height, rated weight, permissible safe hoisting speed, and vertical hoisting rope offset angle limit. These parameters are then input into a PLC. Upon receiving the data, the PLC calculates the trolley following speed, lifting following speed, hoisting angle, and vertical hoisting rope offset angle as the tilt angle during continuous curve hoisting, based on an established mathematical model of the fuel container's curved motion and its trajectory. After initiating the hoisting process, the new fuel containers enter automatic hoisting mode. The PLC adjusts the real-time operating speeds of the translation and lifting mechanisms based on the hoisting angle, tilt angle offset, and hoisting weight to ensure the tilt angle offset meets stability conditions until the hoisting task is completed.

[0059] The system of this invention includes: a hoisting device, a support frame, and a control system; the hoisting device includes: a translation mechanism and a lifting mechanism;

[0060] During the hoisting process, one end of the new fuel container for the nuclear island is fixed to the support, and the other end is connected to the hoisting device via a hoisting rope;

[0061] The lifting weight of the new fuel container for the nuclear island is obtained through the weighing system of the lifting device; the horizontal displacement distance of the translation mechanism is obtained through the horizontal position encoder of the lifting device; the vertical displacement distance of the lifting mechanism is obtained through the lifting position encoder; and the length of the lifting rope is obtained through the drum encoder.

[0062] The lifting weight, vertical displacement distance, horizontal displacement distance, and lifting rope length are transmitted to the control system via bus.

[0063] The control system uses the lifting weight, vertical displacement distance, horizontal displacement distance, and lifting rope length to obtain the lifting angle and tilt deviation; and adjusts the translation speed of the translation mechanism and the lifting speed of the lifting mechanism based on the lifting angle, tilt deviation, and lifting weight to control the tilt deviation of the new fuel container in the nuclear island within a safe range.

[0064] The weighing system is installed at the lower end of the fixed pulley balance arm of the hoisting device; the translation mechanism is a trolley; the horizontal position encoder is installed at the concentric shaft position of the trolley wheels; and the lifting position encoder is installed at the concentric shaft position of the lifting drum.

[0065] Specifically, in combination Figure 2 and Figure 3 Further explanation:

[0066] S1. Collect parameters of the new fuel container in the nuclear island, including:

[0067] The new fuel container for the nuclear island has a radius of R = 17163 mm;

[0068] The maximum stroke of the lifting mechanism is H=20000mm;

[0069] The maximum permissible angle of vertical hoisting rope offset is ±1.5°;

[0070] The maximum permissible speed of the lifting mechanism is 8.33 mm / s (0.5 m / min).

[0071] The maximum permissible speed of the translation mechanism is 33.3 mm / s (2 m / min).

[0072] The rated weight of the new fuel container for the nuclear island is G1 = 480t.

[0073] S2. Enter product information through the HMI (Human Machine Interface). The HMI communicates with the PLC via Profibus-DP, and the PLC stores and calculates the data.

[0074] After receiving the parameters of the new fuel container for the nuclear island, S3 and PLC calculate the following speed of the trolley and the lifting speed, the lifting angle and the tilt angle deviation during the continuous curve hoisting based on the established mathematical model of the curved motion and the running trajectory of the new fuel container for the nuclear island.

[0075] 1) Equation for the hoisting trajectory of the new fuel container for the nuclear island:

[0076] =R-Rcosθ

[0077] Y=Rsinθ

[0078] In the formula, Y represents the displacement of the translation mechanism from its initial position to its final position; R represents the displacement of the lifting mechanism from its initial position to its final position; θ represents the rotation radius of the new fuel container on the nuclear island; and θ represents the hoisting angle.

[0079] 2) Calculate the matching values ​​of the horizontal running speed and the vertical lifting speed of the translation mechanism during continuous curve hoisting; in this embodiment, the translation mechanism is a trolley. Therefore, the matching values ​​of the horizontal running speed and the vertical lifting speed of the translation mechanism are represented by the trolley following speed and the lifting following speed.

[0080] By finding a figure whose area is equal to the area enclosed by the integral of the trolley's theoretical speed and the trolley's acceleration or deceleration curve, we can determine the tilt angle that is less than the maximum allowable tilt angle of the vertical hoisting rope offset.

[0081] Calculate the following speed value of the trolley that meets the conditions for the translation mechanism to follow and lift.

[0082] =0.5·tan(sin -1 ( ))

[0083] In the formula, To increase the operating speed of the lifting mechanism during hoisting, This refers to the runtime.

[0084] And the lifting mechanism that meets the conditions and follows the trolley's speed with a lifting speed value:

[0085] =

[0086] in, The speed at which the translation mechanism operates during hoisting. This refers to the runtime.

[0087] 3) Calculate the hoisting angle using a trajectory method:

[0088] θ=

[0089] 4) Calculate the dip angle deviation. There are two cases of dip angle deviation, such as... Figure 4 The first case shown is when For positive tilt angle skew, the calculation formula is:

[0090]

[0091]

[0092] =A-A2

[0093] In the formula, Indicates positive tilt angle deviation. The real-time length of the hoisting rope is transmitted to the PLC via Profibus DP communication using an encoder installed on the drum position. In this embodiment, A represents the displacement of the trolley from its initial position to its final position; A is... For auxiliary lines The angle between them; A2 is and auxiliary lines The angle between them; The position of the translation mechanism is perpendicular to the length of the running trajectory:

[0094]

[0095] like Figure 5 The second case shown is when This indicates a negative tilt angle:

[0096]

[0097]

[0098] =A2-A

[0099] In the formula, This indicates a negative tilt angle.

[0100] S4. The operator selects the automatic hoisting operation function of the new fuel container of the nuclear island on the operating handle and presses the automatic hoisting start button to enter the automatic hoisting state of the new fuel container of the nuclear island.

[0101] At this time, the PLC continuously determines the hoisting angle θ and the hoisting weight G2; the hoisting weight G2 is transmitted to the PLC via Profibus DP communication using a weighing device installed on the hook.

[0102] In this embodiment, the safe range for the hoisting angle is 89° < θ < 91°; the safe range for the hoisting weight G2 is (G1 - 0.5t) < G2 < (G1 + 0.5t).

[0103] The normal range for tilt angle deviation is The tilt angle skew fault range is and The positive anomaly range for tilt angle deviation is 0.5°. The negative anomaly range for tilt angle deviation is -1.5. .

[0104] In this embodiment, the operating speed of the translation mechanism and the operating speed of the lifting mechanism are adjusted in real time by adjusting the lifting angle, lifting weight, and tilt angle, including:

[0105] Step 1) When the hoisting angle θ is within the safe range of 89° < θ < 91° and the hoisting weight G2 is within the safe weight range of (G1 - 0.5t) < G2 < (G1 + 0.5t), it is determined that the hoisting has been successfully completed and the machine is stopped.

[0106] Step 2) When the hoisting angle θ is not within the safe range of 89° < θ < 91°, then the maximum operating speed of the hoisting mechanism shall be used. Upon startup, the translation mechanism moves at the speed of the trolley following the movement. Run the program and determine the tilt angle β value in real time during operation.

[0107] Step 3) During operation, determine whether the tilt angle β value is within the normal range. In the middle, if so, the lifting mechanism is used to increase the following speed. The translation mechanism operates at the speed of the trolley following the movement. Run the program and jump to step 1) for judgment.

[0108] Step 4) If the tilt angle β value is not within the normal range If it is in the middle, then determine whether it is. If yes, the hoisting should be stopped immediately, indicating a deviation fault; otherwise, continue to determine if... If so, the hoisting should be stopped immediately, indicating a deviation or malfunction.

[0109] If not, continue to determine whether it is in the positive abnormal range. In the middle, if so, the boost mechanism compensates with a +3% increase in following speed (i.e., 103%). The translation mechanism operates by compensating for -3% of the trolley's following speed (i.e., 97%). Run the program and proceed to step 3) to continue verification;

[0110] If not, continue to determine whether it is in the negative abnormal range. In the middle, if the lifting mechanism compensates for a -3% increase in following speed (i.e., 97%), The translation mechanism operates by compensating for +3% of the car's following speed (i.e., 103%). Run the program and jump to step 3) to continue verification.

[0111] Step 5) In step 1), when the hoisting angle θ is within the safe range of 89° < θ < 91°, but the hoisting weight G2 is not within the safe weight range of (G1 - 0.5t) < G2 < (G1 + 0.5t), the lifting mechanism will increase the following speed. The translation mechanism operates at the speed of the trolley following the movement. Run the program, then proceed to step 1) to continue the verification.

[0112] The fully automated hoisting of new nuclear island fuel containers via the aforementioned system requires no human intervention. The hoisting mechanism operates automatically throughout the entire process, reducing safety hazards caused by human error, lowering labor costs, and minimizing time spent on personnel surveying, coordination, and command, thereby improving work efficiency. Furthermore, it eliminates the need for secondary processing or modification of the new nuclear island fuel containers (such as adding hoisting aids, special cages, lifting rings, or altering the container's dimensions). This system is well-suited to the limited space and small dimensions of nuclear power plants, which are ideal for hoisting large-volume new fuel containers, thus improving the space utilization of the hoisting environment.

[0113] The fully automated hoisting of the new nuclear island fuel container adopts a curved hoisting method. Under the monitoring of mathematical models and multiple weight-assisted data, the swaying of the new nuclear island fuel container during the hoisting process is eliminated, improving safety and operational accuracy. Moreover, it is a hoisting mode in which multiple mechanisms cooperate and operate simultaneously, solving the problem that traditional hoisting is limited to vertical lifting and cannot achieve special model curved motion hoisting.

[0114] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
