Description

Technical Field

[0001] This invention relates to the field of crane technology, and more particularly to clean cranes, their control methods, and applications. Background Technology

[0002] Cranes are widely used in various processing plants due to their high operational stability, large lifting capacity, and convenient transportation. Different processing workshops have different cleanliness requirements. For example, food processing workshops, LCD panel processing workshops, and precision instrument assembly workshops often require cleanrooms with a certain level of cleanliness for processing. Cranes experience significant vibration during operation, which can lead to the diffusion of dust particles and a decrease in the cleanroom's cleanliness. This dust may originate from wear and tear on crane components, peeling of surface coatings, and dust particles accumulated on the crane's surface being stirred up by vibration. This is especially problematic for cranes with high vibration levels. Cleanrooms that frequently use cranes, especially beam cranes and bridge cranes, often generate significant dust problems. Although some literature has revealed solutions for installing airflow guiding components or auxiliary dust collection components on the cranes, most of these solutions suffer from complex structures and difficulty in activating the dust collection components in a timely manner according to the actual working environment. This means that many auxiliary components on the cranes used to maintain the clean space often need to be constantly on, leading to additional noise in the working environment. Therefore, how to maintain air cleanliness in the working environment based on the actual air quality during the operation of cleanroom cranes, while also avoiding excessive noise, is a highly relevant and practically significant research topic. Summary of the Invention

[0003] In view of this, the purpose of this invention is to provide a cleanroom crane that is reliable in implementation, flexible in use, simple in structure, and capable of opening and closing the dust collection components according to the working environment of the crane, as well as its control method and application.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this invention is as follows:

[0005] A negative pressure vacuum cleaner assembly, comprising:

[0006] The vacuum cleaner connector is a tubular structure. One end of the connector has multiple branch connectors that connect to the vacuum cleaner connector. The other end of the connector is coaxially and detachably connected to a first vacuum cleaner tube and a cleaning tube from the inside to the outside. A gap is formed between the end of the first vacuum cleaner tube connected to the vacuum cleaner connector and the cleaning tube. The outer periphery of the end of the first vacuum cleaner tube connected to the vacuum cleaner connector has multiple through holes arranged in a ring array. The other end of the first vacuum cleaner tube passes through the inside of the cleaning tube and the exit position is provided with a sealing structure.

[0007] The second suction tube is multiple and connected to the branch connector on the suction head. The periphery of the second suction tube is provided with multiple suction holes that communicate with the inside of the second suction tube.

[0008] The negative pressure generating module is connected to the other end of the first suction pipe and is used to generate negative pressure, so that the second suction pipe connected to the suction connector draws air from its installation environment and flows into the first suction pipe through the suction connector.

[0009] The cleaning module is connected to the cleaning tube and is used to input cleaning fluid into the cleaning tube, so that the cleaning fluid enters the first vacuum tube through the through hole on the first vacuum tube to clean the first vacuum tube.

[0010] The controller is connected to the negative pressure generating module and the cleaning module.

[0011] As a possible implementation, the negative pressure generating module of this solution is further connected to a dust collector, which is used to collect the dust contained in the air transported to the negative pressure generating module by the first suction pipe. A cleaning fluid collector is also connected to the end of the first suction pipe connected to the negative pressure generating module, so that the cleaning fluid flowing to the negative pressure generating module through the first suction pipe under the negative pressure of the negative pressure generating module is intercepted and collected in the cleaning fluid collector.

[0012] As a preferred embodiment, preferably, when the gap between the first suction pipe and the cleaning pipe is filled with cleaning fluid, the gap is 3 to 15 mm.

[0013] As a preferred implementation method, the cleaning tube described in this solution is preferably a flexible tube or a rigid tube.

[0014] As a preferred implementation method, the diameter of the through hole on the first dust suction pipe in this solution is preferably 0.5 to 1.5 mm.

[0015] As a preferred embodiment, the through holes in this solution are multiple and arranged in an N×M ring array on the end of the first vacuum tube near the vacuum connector, where N is the number of rows in the ring array and M is the number of through holes in each row; in addition, the diameter of the multiple through holes gradually decreases along the direction away from the vacuum connector.

[0016] As a preferred embodiment, the first suction pipe is provided with spirally arranged ribs on the inner circumference of the end connected to the suction connector.

[0017] As a preferred implementation method, the cleaning pipe in this solution is further connected to an electrically controlled valve, which is connected to a controller.

[0018] As a preferred embodiment, preferably, a sliding sleeve is slidably inserted into one end of the vacuum cleaner connector. The sliding sleeve is a tubular structure with one open end and one closed end, with its open end inserted into the vacuum cleaner connector. The outer diameter of the sliding sleeve is adapted to the inner diameter of the vacuum cleaner connector. The inner wall of the other end of the vacuum cleaner connector is provided with a constriction structure, and a spring is provided between the constriction structure and the sliding sleeve. One end of the spring is fixedly connected to the constriction structure, and the other end of the spring is fixedly connected to the open end of the sliding sleeve. The sliding sleeve is also provided with a clearance opening corresponding to each branch connector of the vacuum cleaner connector. When the negative pressure generating module operates with the first negative pressure parameter, the sliding sleeve compresses the spring to the first compression amount, so that the clearance opening is aligned with the branch connector. When the negative pressure generating module operates with the second negative pressure parameter, the sliding sleeve compresses the spring to the second compression amount, so that the clearance opening is completely misaligned with the branch connector, thus isolating the branch connector from the interior of the vacuum cleaner connector.

[0019] Among them, the negative pressure value corresponding to the first negative pressure parameter is less than the negative pressure value corresponding to the second negative pressure parameter, and the first compression amount is less than the second compression amount.

[0020] Based on the above, the present invention also provides a cleanroom crane, which includes a pair of oppositely arranged rails and a crossbeam spanning the rails and connected to the rails via a traveling mechanism, and an electric hoist connected to the underside of the crossbeam via a translation mechanism, and further includes the negative pressure dust collection assembly described above.

[0021] The number of the vacuum cleaner connectors is one or more, which are arranged on the walking mechanism, the crossbeam and / or the translation mechanism, and the second vacuum cleaner pipe connected to the vacuum cleaner connector extends to both ends of the walking mechanism, the crossbeam and / or the translation mechanism.

[0022] As a preferred implementation method, the crane in this solution is preferably equipped with a vibration monitoring unit and an air quality monitoring module on its crossbeam, traveling mechanism, and translation mechanism, and the vibration monitoring unit and air quality monitoring module are all connected to the controller.

[0023] Based on the above, the present invention also provides a cleanroom crane control method, which includes the cleanroom crane described above, and the control method includes:

[0024] S01. Respond to the crane's start signal, acquire the crane's working parameters in real time, and generate working status data;

[0025] S02. Vibration signals are collected from the crane's crossbeam, traveling mechanism, and / or translation mechanism. At the same time, the air quality at the location of the crossbeam, traveling mechanism, and / or translation mechanism is monitored, and vibration monitoring data and air quality monitoring data are generated respectively.

[0026] S03. Obtain air quality monitoring data and start the negative pressure generation module according to preset conditions to enable the second suction pipe connected to the suction connector on the crossbeam, walking mechanism and / or translation mechanism to perform suction work.

[0027] S04. Acquire air quality monitoring data and vibration monitoring data, perform correlation judgment on them according to preset conditions, and output the correlation judgment result;

[0028] S05. Obtain the correlation judgment result. When the correlation judgment result meets the preset requirements, adjust the working parameters of the crane to reduce the vibration generated during its operation.

[0029] As a preferred implementation method, solution S03 preferably includes:

[0030] S031. Obtain air quality monitoring data, compare it with preset thresholds, and generate comparison results;

[0031] S032. Obtain the comparison result. When the comparison result indicates that the air quality monitoring data is greater than the preset threshold, activate the negative pressure generation module according to the area corresponding to the air quality monitoring data, so that the second suction pipe connected to the suction connector on the crossbeam, the walking mechanism and / or the translation mechanism can perform suction work.

[0032] As a preferred implementation method, solution S04 preferably includes:

[0033] S041. Acquire air quality monitoring data and vibration monitoring data generated at different time points;

[0034] S042. Perform correlation judgment on air quality monitoring data and vibration monitoring data generated at different time points in the same area in chronological order, and generate judgment results indicating positive correlation, negative correlation or no correlation.

[0035] As a preferred implementation method, solution S05 preferably includes:

[0036] S051. Obtain the judgment result. When the judgment result indicates that the air quality monitoring data and vibration monitoring data are positively correlated, adjust the working parameters of the crane to reduce the vibration generated during its operation.

[0037] As a preferred implementation method, this solution further includes:

[0038] S06. Air quality is detected at the end of the first suction pipe near the negative pressure generating module. The air quality data is then compared with the air quality data at the locations of the crossbeam, the traveling mechanism, and / or the translation mechanism. When the difference between the two values ​​is greater than a preset threshold, the cleaning module is activated to input cleaning fluid into the cleaning pipe at a preset flow rate. The cleaning fluid enters the first suction pipe through the through-hole to clean it. After a preset cleaning time, the cleaning module stops working.

[0039] Based on the above, the present invention also provides a computer-readable storage medium storing at least one instruction, at least one program, code set, or instruction set, wherein the at least one instruction, at least one program, code set, or instruction set is loaded and executed by a processor to implement the cleanroom crane control method described above.

[0040] Compared with the prior art, the present invention, employing the above technical solution, has the following advantages: The ingenious design of this solution utilizes a combination of components such as a suction connector, a first suction pipe, a second suction pipe, a cleaning pipe, a negative pressure generating module, a cleaning module, and a controller to form a negative pressure suction assembly. This allows the first suction pipe to be cleaned as needed using the cleaning module after long-term use, by introducing cleaning fluid. The specific structure of the cleaning module, negative pressure generating module, first suction pipe, and cleaning pipe eliminates the need for manual cleaning, achieving a degree of automated cleaning. Furthermore, this solution proposes applying the negative pressure suction assembly to cleanroom cranes. The suction connector and its connected components are placed on vibration-prone parts of the cleanroom crane, such as the traveling mechanism, crossbeams, and translation mechanism. Combined with vibration monitoring units and air quality monitoring modules installed on the crane, the negative pressure suction assembly can be activated in a timely manner, thereby improving and stabilizing the air quality in the cleanroom crane's working environment to a relatively clean level. This solution is reliable, flexible in use, and simple in structure. Attached Figure Description

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] like Figures 1 to 5 As shown in one embodiment, a negative pressure dust collection component includes:

[0054] The vacuum cleaner connector 1 is a tubular structure. One end of the connector has multiple branch connectors 11 that connect to the inside of the vacuum cleaner connector 1. The other end of the connector is coaxially and detachably connected to a first vacuum cleaner tube 12 and a cleaning tube 13 from the inside to the outside. A gap 131 is formed between the end of the first vacuum cleaner tube 12 connected to the vacuum cleaner connector 1 and the cleaning tube 13. The outer periphery of the end of the first vacuum cleaner tube 12 connected to the vacuum cleaner connector 1 has multiple through holes 121 arranged in a ring array. The other end of the first vacuum cleaner tube 12 passes through the inside of the cleaning tube 13 and the exit position is provided with a sealing structure (or a closed structure).

[0055] The second suction pipe 14 is multiple and connected to the branch connector 11 on the suction connector 1. The periphery of the second suction pipe 14 is provided with multiple suction holes 141 that communicate with the interior of the second suction pipe 14.

[0056] The negative pressure generating module 2 is connected to the other end of the first suction pipe 12 and is used to generate negative pressure, so that the second suction pipe 12 connected to the suction connector 1 draws air from its installation environment and flows into the first suction pipe 12 through the suction connector 1.

[0057] The cleaning module 3 is connected to the cleaning tube 13 and is used to input cleaning fluid into the cleaning tube 13, so that the cleaning fluid enters the first vacuum tube 12 through the through hole 121 on the first vacuum tube 12 to clean the first vacuum tube 12. In this embodiment, the cleaning fluid can be water or other water with added surfactants.

[0058] Controller 4 is connected to negative pressure generating module 2 and cleaning module 3.

[0059] In this embodiment, the negative pressure generating module can be a negative pressure generating component used in existing commercially available vacuum cleaners. In this structural form, as a possible implementation, the negative pressure generating module is further connected to a dust collector. The dust collector is used to collect the dust contained in the air transported from the first suction pipe 12 to the negative pressure generating module 2. A cleaning fluid collector is also connected to the end of the first suction pipe 12 connected to the negative pressure generating module, so that the cleaning fluid flowing to the negative pressure generating module 2 through the first suction pipe 12 under the negative pressure is intercepted and collected in the cleaning fluid collector. The cleaning fluid collector can be a collection container set vertically below the first suction pipe 12. By gravity, the liquid in the first suction pipe 12 flows into the collection container to complete the gas-liquid separation. In this embodiment, the working principle of the cleaning fluid collector and the dust collector can also refer to other forms of commercially available products that can achieve the corresponding functions. The main advantage of this embodiment is that it cleverly achieves the relevant functional allocation through the negative pressure generating module 2 and the vacuum connector 1 with a specific structure.

[0060] Regarding the transport of the medium, this solution can install an electrically controlled valve between the cleaning module 3 and the cleaning pipe 13, and the electrically controlled valve is connected to the controller 5. Under this structure, the electrically controlled valve can be closed when the cleaning module 3 is not needed, so that the cleaning pipe 13 will not cause the problem of negative pressure diversion when the negative pressure generating module 2 is working.

[0061] Regarding cleaning, as a preferred implementation method, in this solution, when the first suction pipe 12 and the cleaning pipe 13 are filled with cleaning fluid, the gap 131 is 3-15mm apart. Under this structure, the negative pressure generating module 2 and the cleaning module 3 can work simultaneously. On the one hand, the cleaning module 3 delivers cleaning fluid, and on the other hand, the electronic control valve is opened. The negative pressure generated by the negative pressure generating module 2 serves as additional delivery power for the cleaning fluid delivered by the cleaning pipe 13, causing the cleaning fluid to flow through the gap 131 into the through hole 121 of the first suction pipe 12, and then into the first suction pipe 12, flowing in the direction close to the negative pressure generating module 2. At this time, the second suction pipe 13 can also maintain normal operation. Technicians only need to control the input flow rate of the cleaning fluid to avoid excessive cleaning fluid crowding the first suction pipe 12 and the cleaning fluid collector at one time. This can be achieved by adjusting the parameters to achieve quantitative and corresponding values.

[0062] Regarding the selection of materials for the cleaning tube 13, as a preferred implementation method, the cleaning tube 13 in this solution can preferably be a flexible tube or a rigid tube. When it is a flexible tube, when there is negative pressure in the vacuum connector 1, the cleaning tube 13 will undergo partial deformation, making it close to the first vacuum tube 12, so that the gap 131 becomes smaller, and avoids more dust from entering the gap 131 and forming a sanitary dead corner.

[0063] In addition, as a preferred embodiment, the diameter of the through hole 121 on the first vacuum tube 12 is preferably 0.5-1.5mm (too small may cause blockage or insufficient water flow, failing to achieve the cleaning effect; too large may cause a large amount of liquid to flow in at once, resulting in some cleaning liquid overflowing to the outside of the vacuum connector 1). As a preferred embodiment, the number of through holes 121 is multiple and arranged in an N×M ring array on the end of the first vacuum tube 12 near the vacuum connector 1, where N is the number of rows in the ring array and M is the number of through holes 121 in each row. Furthermore, the diameter of the multiple through holes 121 gradually decreases along the direction away from the vacuum connector 1. With this structural form, the through holes 121 can, to a certain extent, prevent a large amount of cleaning liquid from entering the first vacuum tube 12 from the part of the through hole 121 away from the vacuum connector 1 when the cleaning module 3 cleans the first negative pressure tube 12, thus making it difficult to clean the part near the vacuum connector 1.

[0064] In this solution, the first suction pipe 12 can be a rigid pipe. However, during the airflow process, the flow rate is relatively slower closer to the inner wall, which causes dust to accumulate and cannot be blown away in time. It may also be affected by adverse adsorption factors such as static electricity, causing dust to accumulate on the inner wall of the end of the first suction pipe 12 connected to the suction connector. As a preferred embodiment, the first suction pipe 12 is provided with spirally arranged baffles 122 on the inner circumference of the end connected to the suction connector 1. Through the baffles 122, the air entering the first suction pipe 12 from the suction connector 1 is formed into a spiral airflow by the baffles 122, and the end of the first suction pipe 12 near the suction connector 1 is flushed by the airflow. At the same time, when the cleaning module 3 is working, it can also help to form a spiral water flow to improve the cleaning effect.

[0065] Since the number of second suction pipes 14 connected to the suction connector 1 in this solution may increase as needed, in this case, if the first suction pipe 12 is cleaned simultaneously and external air is sucked in, the negative pressure generating module 2 needs to have a large power. This will cause the negative pressure generating module 2 to generate a lot of noise and vibration. In order to reduce its performance dependence, combined with Figure 6 or Figure 7As shown, as another preferred embodiment of the vacuum cleaner connector 1 in this solution, preferably, a sliding sleeve 17 is slidably inserted into one end of the vacuum cleaner connector 1. The sliding sleeve 17 is a tubular structure with one open end and one closed end. Its open end is inserted into the vacuum cleaner connector 1. The outer diameter of the sliding sleeve 17 is adapted to the inner diameter of the vacuum cleaner connector 1. The inner wall of the other end of the vacuum cleaner connector 1 is provided with a constriction structure 15, and a spring 16 is provided between the constriction structure 15 and the sliding sleeve 17. One end of the spring 16 is fixedly connected to the constriction structure 15, and the other end of the spring 16 is fixedly connected to the open end of the sliding sleeve 17. The sliding sleeve 17 is also provided with a corresponding clearance opening 171 for each branch connector 11 of the vacuum cleaner connector 1. When the negative pressure generating module operates with the first negative pressure parameter, the sliding sleeve 17 compresses the spring 16 to the first compression amount, so that the clearance opening 171 is directly opposite the branch connector 11 (i.e., Figure 6 As shown), when the negative pressure generating module 2 operates with the second negative pressure parameter, the sliding sleeve 17 compresses the spring 16 to the second compression amount, completely misaligning the clearance opening 171 with the branch connector 11, thus isolating the branch connector 11 from the inside of the vacuum connector 1 (i.e., Figure 7 (as shown); when the negative pressure generating module 2 operates with a value between the first negative pressure parameter and the second negative pressure parameter, it avoids the opening 171 from partially blocking the branch connector 11. In this case, due to the smaller diameter and increased negative pressure, the airflow velocity input from the branch connector 11 into the vacuum connector 1 is increased, so the impact on the second vacuum tube 14 is relatively small.

[0066] Among them, the negative pressure value corresponding to the first negative pressure parameter is less than the negative pressure value corresponding to the second negative pressure parameter, and the first compression amount is less than the second compression amount.

[0067] exist Figures 1 to 7 Based on what is shown, further combine Figure 8 or Figure 9 As shown, based on the above, this embodiment also provides a cleanroom crane, which includes a pair of oppositely arranged rails 61 and a crossbeam 6 spanning the rails 61 and connected to the rails 61 via a traveling mechanism 62, and an electric hoist 7 connected to the underside of the crossbeam 6 via a translation mechanism 71. The cleanroom crane of this embodiment also includes the negative pressure dust collection assembly 5 mentioned above.

[0068] The number of the vacuum cleaner connectors 1 is one or more, and they can be arranged on the walking mechanism 61, the crossbeam 6 and / or the translation mechanism 71. The second vacuum cleaner pipe 14 connected to the vacuum cleaner connector 1 extends to both ends of the walking mechanism 61, the crossbeam 6 and / or the translation mechanism 71.

[0069] The appendix corresponding to this implementation plan Figure 8The illustration only shows the negative pressure suction assembly 5 installed on the traveling mechanism 61 to draw air into the working environment where the traveling mechanism is located. This example is only one possible application of the negative pressure suction assembly 5 in a cleanroom crane according to this embodiment. Other possible installation positions are also possible, namely, installation on the traveling mechanism 61, the crossbeam 6 and / or the translation mechanism 71.

[0070] Since the working environment of the cleanroom crane also has other negative pressure or air purification equipment in operation, the negative pressure dust collection component 5 does not need to be in operation at all times during the operation of the cleanroom crane. Therefore, as a preferred implementation method, it is assumed that the crossbeam 6, traveling mechanism 61, and translation mechanism 71 of the crane in this scheme are all equipped with negative pressure dust collection components 5. The crossbeam 6, traveling mechanism 61, and translation mechanism 71 of the crane in this scheme are all equipped with vibration monitoring units 8 and air quality monitoring modules 9, and the vibration monitoring units 8 and air quality monitoring modules 9 are all connected to the controller 5.

[0071] In this implementation scheme, the vibration monitoring unit 8 and the air quality monitoring module 9 are both existing commercially available products. The main purpose of this scheme is to ingeniously use them to detect the working vibration and air quality of the working environment of the clean crane.

[0072] Combination Figure 10 As shown above, the control method for the cleanroom crane in this implementation scheme includes:

[0073] S01. Respond to the crane's start signal, acquire the crane's working parameters in real time, and generate working status data;

[0074] S02. Vibration signals are collected from the crane's crossbeam, traveling mechanism, and / or translation mechanism. At the same time, the air quality at the location of the crossbeam, traveling mechanism, and / or translation mechanism is monitored, and vibration monitoring data and air quality monitoring data are generated respectively.

[0075] S03. Obtain air quality monitoring data and start the negative pressure generation module according to preset conditions to enable the second suction pipe connected to the suction connector on the crossbeam, walking mechanism and / or translation mechanism to perform suction work.

[0076] S04. Acquire air quality monitoring data and vibration monitoring data, perform correlation judgment on them according to preset conditions, and output the correlation judgment result;

[0077] S05. Obtain the correlation judgment result. When the correlation judgment result meets the preset requirements, adjust the working parameters of the crane to reduce the vibration generated during its operation.

[0078] Regarding the adaptive startup of the negative pressure dust collection component, specifically, solution S03 includes:

[0079] S031. Obtain air quality monitoring data, compare it with preset thresholds, and generate comparison results;

[0080] S032. Obtain the comparison result. When the comparison result indicates that the air quality monitoring data is greater than the preset threshold, activate the negative pressure generation module according to the area corresponding to the air quality monitoring data, so that the second suction pipe connected to the suction connector on the crossbeam, the walking mechanism and / or the translation mechanism can perform suction work.

[0081] In order to determine whether the decline in air quality during crane operation is caused by crane vibration, as a preferred implementation method, solution S04 preferably includes:

[0082] S041. Acquire air quality monitoring data and vibration monitoring data generated at different time points;

[0083] S042. Perform correlation judgment on air quality monitoring data and vibration monitoring data generated at different time points in the same area in chronological order, and generate judgment results indicating positive correlation, negative correlation or no correlation.

[0084] As a preferred implementation method, solution S05 preferably includes:

[0085] S051. Obtain the judgment result. When the judgment result indicates that the air quality monitoring data and vibration monitoring data are positively correlated, adjust the working parameters of the crane to reduce the vibration generated during its operation.

[0086] Reducing the operating vibration of a crane can be achieved by reducing its moving speed, reducing its acceleration, and so on.

[0087] In order to enable flexible cleaning of the first suction pipe according to the working status of the negative pressure suction component, as a preferred implementation method, this solution further includes:

[0088] S06. Air quality is detected at the end of the first suction pipe near the negative pressure generating module. The air quality data is then compared with the air quality data at the locations of the crossbeam, the traveling mechanism, and / or the translation mechanism. When the difference between the two values ​​is greater than a preset threshold, the cleaning module is activated to input cleaning fluid into the cleaning pipe at a preset flow rate. The cleaning fluid enters the first suction pipe through the through-hole to clean it. After a preset cleaning time, the cleaning module stops working.

[0089] The above description is only a part of the embodiments of the present invention and does not limit the scope of protection of the present invention. Any equivalent device or equivalent process transformation made based on the content of the present invention specification and drawings, or direct or indirect application in other related technical fields, are similarly included within the patent protection scope of the present invention.
