Description

Technical Field

[0002] Currently, overhead crane hoisting of billets is a crucial step in the steel rolling production process. The overhead crane operator typically communicates with on-site workers via walkie-talkie to confirm the target position of the billet. The operator then operates the clamping crane to move the trolley above the target position, lowers it close to the billet position, confirms that the clamps are at the center of gravity of the billet, opens the clamps wider than the width of the billet, and performs the billet clamping operation. After clamping, the crane is lifted and test-lifted before being moved to the target position for unloading, completing one hoisting cycle.

[0003] However, the existing overhead crane hoisting method for transporting billets relies more on uncontrollable external factors such as the skill level and experience of the crane operator. This can lead to poor positioning accuracy when the crane operator misremembers the hoisting position information or grabs the billet from a non-center-of-gravity position. In severe cases, this can affect the rolling of steel billets, thereby affecting the production quality of steel plates or causing production accidents. Summary of the Invention

In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

The term "two or more" includes two or more cases.

[0020] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of steelmaking equipment control technology.

[0021] Currently, the existing overhead crane lifting and casting billet operation methods rely more on uncontrollable external factors such as the skill level and experience of the crane operator. This can lead to poor positioning accuracy when the crane operator misremembers the lifting position information or grasps the billet at a non-center of gravity position. In severe cases, this can affect the rolling of steel billets, thereby affecting the production quality of steel plates or causing production accidents.

[0022] Based on this, the embodiments of this application provide a control method, a lifting system and device for overhead cranes, and a lifting device for overhead cranes. The embodiments provided by this application solve the technical problem that the positioning accuracy of overhead cranes during billet lifting operations is poor, which can seriously affect the rolling of steel billets and thus affect the production quality of steel plates or cause production accidents. The embodiments provided by this application can improve the accuracy of overhead crane billet lifting operations, reduce the error rate in the rolling process of steel billets, thereby reducing the impact on the production quality of steel plates and reducing the incidence of production accidents.

[0023] Figure 1 A flowchart illustrating a control method for lifting equipment using a bridge crane, as provided in an embodiment of this application, is shown. Figure 1 As shown, the control method for lifting and transporting by a bridge crane includes the following steps: S101. Based on the scheduling instruction for scheduling the target billet, determine the target operating position of the target bridge crane.

[0024] In this step, before determining the target working position of the target bridge crane, the embodiment provided in this application first needs to establish a preset billet material database before the operation, that is, the specific storage location of different types of billets. After establishing the preset billet material database, the embodiment provided in this application will receive a scheduling instruction for scheduling the target billet, and then determine the target working position where the target bridge crane needs to lift and position the target billet according to the scheduling instruction of the target billet.

[0025] It should be noted that the database used in the construction of the preset billet material database in the embodiments provided in this application can be customized and used according to different application scenarios and usage conditions. That is, the preset billet material database can be different in different scenarios.

[0026] It is understood that the preset billet warehouse material database in the embodiments provided in this application can be accurately positioned and displayed using a crane display, so that the crane operator can more intuitively observe the target working position of the target billet.

[0027] Specifically, the pre-set billet warehouse material database can be established based on the material information and stack coordinates of all billets in the billet warehouse area. Specifically, a billet location distribution model is constructed in a visualization map, and then the visualization map and billet location distribution model are pushed to the interactive display terminal in the crane operator's cab for display, forming a visualized billet warehouse material database.

[0028] S102. Compare the target working position with the real-time position of the target bridge crane to determine whether the moving components of the target bridge crane have reached the preset position area.

[0029] In this step, after determining the target working position of the target bridge crane, the embodiment provided in this application will collect the real-time position of the target bridge crane in real time based on the crane positioning module installed above the crane platform and the trolley cable track, and compare the target working position and the real-time position in real time to determine whether the moving components of the target bridge crane, the trolley and the trolley, have reached the preset position area, so as to realize the interlocking of the positioning module with the bridge crane hoisting and scheduling module.

[0030] S103. When the moving component trolley and the large trolley reach the preset position area, control the target bridge crane to lift the target billet.

[0031] In this step, the embodiments provided in this application will determine and collect the position information of the moving component trolley in real time, and determine in real time whether the moving component trolley has reached the preset position area. When the moving component trolley reaches the preset position area, the descent interlock function will be released, and at this moment the overhead crane will be operated to perform descent hoisting operation, that is, the target bridge crane will be controlled to hoist the target billet.

[0032] It should be noted that in the embodiments provided in this application, when the moving component trolley and the large trolley have not reached the preset position area, the overhead crane cannot perform the lowering operation. At this time, the billet hoisting scheduling module and the positioning module will perform precise positioning interlocking.

[0033] In one feasible embodiment, the scheduling instruction includes identification information of the target billet. Based on the scheduling instruction for scheduling the target billet, the target operating position of the target bridge crane is determined, including: Based on the identification information of the target billet in the scheduling instruction, the location of the target billet is determined from the preset billet warehouse material database; based on the location of the target billet, the target coordinate range of the target billet is determined; based on the target coordinate range, the target operating position of the target bridge crane is determined.

[0034] In the above-described embodiments, after obtaining the scheduling instruction for scheduling the target billet, the embodiment of this application determines the identification information representing the target billet from the scheduling instruction. Then, based on the identification-storage location mapping relationship in the preset billet material database, it determines the storage location of the target billet. After determining the storage location of the target billet, it begins to locate the target coordinate range of the target billet storage in detail. Then, based on the target coordinate range of the target billet storage, it determines the target working position of the target bridge crane and controls the target bridge crane to move in the direction of the target working position, and collects the position information of the target bridge crane in real time during the movement.

[0035] It should be noted that the target bridge crane is used to characterize the bridge crane used for subsequent lifting of the aforementioned target billet.

[0036] In one feasible embodiment, comparing the target operating location with the real-time location of the target bridge crane to determine whether the moving components (trolleys) on the target bridge crane have reached the preset location area includes: Based on the real-time position of the bridge crane and the target coordinate range of the target billet storage in the target working position, determine whether the moving components of the target bridge crane have reached the preset position area.

[0037] In the above-described embodiment, the real-time position coordinates of the bridge crane are compared with the target coordinate range where the target billet is stored to determine whether the real-time position coordinates fall within the target coordinate range. Based on the above determination result, it is determined whether the moving component trolley on the target bridge crane has reached the preset position area. When the moving component trolley has not reached the preset position area where operation is permitted, the actuator of the moving component trolley is prohibited from starting operation. When the moving component trolley reaches the preset position area where operation is permitted, the actuator is permitted to start operation.

[0038] It should be noted that if the real-time position coordinates fall within the target coordinate range, it is determined that the moving components of the target bridge crane have reached the preset position area; if the real-time position coordinates do not fall within the target coordinate range, it is determined that the moving components of the target bridge crane have not reached the preset position area.

[0039] In one feasible embodiment, based on the real-time position of the bridge crane and the target coordinate range where the target billet is stored in the target working position, determining whether the moving component trolley on the target bridge crane has reached the preset position area includes: Obtain the actual contour information of the target billet; based on the actual contour information, determine the center of gravity region of the target billet and generate the coordinate range of the center of gravity region corresponding to the center of gravity region; when the real-time position of the bridge crane is determined to fall into the coordinate range of the center of gravity region and the target coordinate range, determine that the moving components of the target bridge crane have reached the preset position area.

[0040] In the embodiments provided in this application, when determining whether the moving component trolley on the target bridge crane has reached the preset position area, it is first necessary to obtain the actual contour information of the target billet to be lifted. Then, based on the actual contour information, the center of gravity region of the target billet is determined, and then the coordinate range of the center of gravity region corresponding to the center of gravity region is determined. Finally, based on the coordinate range of the center of gravity region and the target coordinate range, it is determined whether the moving component trolley on the target bridge crane has reached the preset position area.

[0041] It should be noted that if the real-time position of the bridge crane in the embodiments provided in this application falls within both the coordinate range of the center of gravity region and the target coordinate range, it is determined that the moving component trolley on the target bridge crane has reached the preset position area. At this time, a position verification pass signal is generated, and then based on the position verification pass signal, an interlocking release command is sent to the interlocking controller of the lowering mechanism of the moving component trolley on the target bridge crane. If the real-time position of the bridge crane only falls within the coordinate range of the center of gravity region, or the real-time position of the bridge crane only falls within the target coordinate range, it is determined that the moving component trolley on the target bridge crane has not reached the preset position area.

[0042] It is understood that the setting of the center of gravity region of the target billet in the embodiments provided in this application can be customized and selected according to different application scenarios and usage conditions. The center of gravity region of the target billet in the embodiments provided in this application can be specifically set as the center position of the target billet.

[0043] In one feasible embodiment, after comparing the target working location with the real-time location of the target bridge crane to determine whether the moving component trolley on the target bridge crane has reached the preset location area, the method further includes: When the moving component trolley and the trolley have not reached the preset position area, the position deviation amount and position deviation direction are determined based on the real-time position of the bridge crane and the target working position, and navigation prompt information on the position deviation amount and position deviation direction is generated.

[0044] In the above-described embodiments, when it is determined that the trolley and the moving component trolley have not reached the preset position area, the position deviation amount and position deviation direction between the trolley and the preset position area are determined based on the real-time position of the bridge crane and the target working position. When the position deviation amount is less than the preset deviation threshold and the current running speed is greater than zero, a deceleration control command is generated and the deceleration control command is sent to the overhead crane.

[0045] In one feasible embodiment, the method further includes: During the descent of the moving component trolleys on the target bridge crane, the dynamic position of the moving component trolleys is collected in real time; when the dynamic position is determined to be outside the coordinate range of the center of gravity area, the descent moving component trolleys are controlled to hover or rise.

[0046] In the above-described embodiments, when the dynamic position of the moving component trolley exceeds the coordinate range of the center of gravity area, the descent moving component trolley is controlled to interrupt or revert to the current operation. Specifically, the descent moving component trolley may be controlled to hover or rise.

[0047] Compared with the prior art, the control method for overhead crane hoisting provided in this application can determine the target working position of the target overhead crane based on the scheduling instruction for scheduling the target billet. Then, it compares the target working position with the real-time position of the overhead crane to determine whether the moving components of the overhead crane have reached the preset position area. When the moving components of the overhead crane reach the preset position area, it controls the target overhead crane to hoist the target billet. This application can improve the accuracy of overhead crane hoisting of billets, reduce the error rate of the steelmaking billet rolling process, thereby reducing the impact on the production quality of steel plates and reducing the incidence of production accidents.

[0053] The interlocking hoisting device 250 is used to control the trolley of the moving component to descend when the data processing module 240 determines that the moving component trolley has reached the preset position area, so as to perform hoisting of the target billet.

[0054] In the above-described embodiments, the data processing module 240 in this application prevents the interlocking hoisting device 250 from starting by sending an electrical interlock signal to the drive controller of the interlocking hoisting device 250. The electrical interlock signal disconnects the enable circuit of the drive controller.

[0055] Compared with the prior art, the overhead crane hoisting system 200 provided in this application can achieve precise positioning and visualization of the billet position, thereby improving the accuracy of the overhead crane hoisting billet operation, reducing the error rate of the steelmaking billet rolling process, thereby reducing the impact on the production quality of steel plates, reducing the incidence of production accidents, and this application can be interlocked with the storage position of the target billet.
