Description

Technical Field

[0001] The present invention relates to the technical field of power engineering material management, and in particular to an intelligent management system for power engineering materials that combines traditional shelf units with Internet of Things technology and a key mechanism design thereof. Background Art

[0002] In the construction of power projects, a large number of materials such as distribution boxes and cables need to be centrally stored and efficiently dispatched. There are many problems with the traditional material storage management method: first, the storage density is low and it takes up a lot of space; second, the real-time status and location of materials are difficult to accurately control, and the search and deployment efficiency is low; third, the material storage and retrieval operations mainly rely on manual labor, which is labor-intensive and prone to errors. These problems have aggravated the complexity of material management and affected the efficient advancement of power projects.

[0003] In order to improve the efficiency of bulk material management, modern warehousing systems often use narrow aisle shelves with automatic guided vehicles (AGVs) or forklifts and other handling equipment. However, this traditional system also has some obvious defects:

[0004] 1. It occupies a large area, and sufficient space must be reserved between each row of shelves as a passage. In addition, the number of shelves and the spacing between shelves are usually fixed and cannot be flexibly adjusted, resulting in low storage efficiency;

[0005] 2. High investment cost. AGV and forklift are expensive and require complex path planning and navigation system support.

[0006] 3. The operating efficiency is limited. The operating speed of AGV and forklift is restricted in many aspects. The storage and retrieval efficiency is low and the goods are easily damaged.

[0007] In recent years, the Internet of Things technology has shown broad application prospects in the field of material management. In view of the shortcomings of the existing technology, the present invention designs an intelligent management system for power engineering materials based on the Internet of Things. The system integrates advanced equipment such as improved high-density aisle-free shelves, smart tags, sensors, and monitoring equipment, which can realize real-time monitoring, efficient storage, precise scheduling, and timely recycling of materials throughout their life cycle, reduce waste, improve resource utilization, and reduce manpower input. The system supports automated storage and retrieval operations, improves operating efficiency and response speed, ensures that the project is completed on schedule with high quality, and also improves the safety of the overall operation, providing strong support for the smooth implementation of power engineering. Summary of the invention

[0008] In view of the above problems, the present invention provides an intelligent management system for power engineering materials that combines traditional shelf units with Internet of Things technology and realizes automatic locking, release and efficient circulation of layer trays between shelves and conveying systems through innovative mechanism design.

[0009] The invention object of the present invention is achieved through the following technical solution: A docking locking mechanism for a middle-layer pallet of a shelf, comprising:

[0010] Layer tray;

[0011] A movable connecting piece is hinged at each corner of the main body of the layer support plate; the movable connecting piece can be rotated to a hidden state or a protruding connectable state, and the movable connecting piece is kept in the protruding connectable state by an elastic piece;

[0012] A bottom plate is provided between two movable connecting members on the same side, left and right or front and back;

[0013] A rotatable turntable is mounted on each base plate; the movable connecting member is connected to the turntable by a belt or rope, and the movable connecting member can be driven to rotate when the turntable rotates;

[0014] A switching starter engaged with the turntable thread, which can drive the turntable to rotate when the switching starter moves;

[0015] The hinged trigger is installed on the bottom plate, and the hinged trigger includes a long strip body, a shaft sleeve and a pressure rod arranged perpendicular to the body. The pressure rod contacts the switching starter, and the movement of the body can drive the pressure rod to push or release the switching starter. The benefit is that it is a docking locking mechanism that can reliably lock and release the layer tray. Through the combined design of the movable connecting part, the turntable, the switching starter and the hinged trigger, the automatic and efficient locking and releasing control is realized, and the flexibility and automation level of material management are improved.

[0016] Preferably, a threaded hole is provided at the center of the switching starter, and a ball screw transmission mechanism is adopted in the threaded hole. The benefit is that the transmission efficiency of the switching starter is improved, the driving torque is reduced, and the energy consumption and mechanism wear are reduced by adopting the ball screw transmission mechanism.

[0017] Preferably, the free end of the switching starter is configured to have a ring-shaped surrounding groove structure. The benefit is that the ring-shaped surrounding groove structure design of the free end of the switching starter increases the contact area with other components and improves the reliability of operation.

[0018] In view of the above problems, the present invention also provides an intelligent management system for power engineering materials based on Internet of Things technology, comprising:

[0019] A plurality of shelf units, each shelf unit comprises a shelf body standing on the ground and capable of providing a plurality of storage spaces in a height direction and a movable layer pallet placed in the shelf body;

[0020] Guide rails arranged on both sides of the upper edge of the shelf unit, a carrying assembly for horizontally transporting the layer pallet on the guide rails, and a vertical pick-and-place assembly for vertically moving the layer pallet out of the shelf body;

[0023] Preferably, the vertical pick-and-place assembly in the shelf unit includes a linear conveyor and a rotating arm mechanism, which can rotate to the bottom of the layer tray to lift or insert it into the shelf body. The benefit is that the rotating arm mechanism design of the vertical pick-and-place assembly can accurately and efficiently lift or insert the layer tray from the shelf body, which is the key to realizing automated vertical pick-and-place.

[0024] Preferably, the layer tray is provided with the above-mentioned docking locking mechanism. The benefit lies in that the innovative docking locking mechanism is integrated with the layer tray to provide hardware support for the reliable locking and releasing of the layer tray, which is the basis for realizing the entire intelligent management system.

[0025] Preferably, a passive release mechanism is provided on the layer tray, which cooperates with the rotating part of the rotating arm mechanism, and is used to control its locking or releasing state when the layer tray is lifted to the carrying assembly or inserted into the shelf body. The benefit lies in that the cooperation design of the passive release mechanism and the rotating arm mechanism realizes the efficient and reliable transfer of the layer tray between the shelf and the carrying assembly without adding a power source, which reflects the economical and practical characteristics.

[0026] Preferably, the passive release mechanism includes a guide release hole on the body of the hinged trigger to prevent the body from interfering with other parts when the body is swung; a positioning column located in the guide release hole of the hinged trigger; the height of the positioning column is set so that when the body of the hinged trigger is closest to the layer support plate, its height is the same as or slightly lower than the side of the body facing away from the layer support plate. The benefit is that the setting of the guide release hole prevents the body of the hinged trigger from interfering with other parts when the body is swung, ensuring the flexibility of the mechanism movement. The height design of the positioning column can accurately control the position of the hinged trigger when it is released, provide a reset space for the switching starter, and ensure the reliability of the release action.

[0027] Preferably, the carrier assembly is provided with a fence to limit the position and posture of the layer pallet during horizontal transportation and a grabbing mechanism for grabbing the layer pallet; at both ends of the shelf unit guide rail extension direction, a space area beyond the shelf body is provided for setting up transportation tools or operation and storage facilities connected with the external logistics system. The benefits are: the setting of the fence and the grabbing mechanism limits the displacement and tilt of the layer pallet during horizontal transportation, ensuring the stability and safety of the materials; the design of the beyond area enables the system to seamlessly connect with the external logistics system, and reserves space for manual operation and facility storage, improving the comprehensiveness and integration of the system.

[0028] In summary, the present invention has the following advantages compared with the prior art:

[0029] 1. Innovative structural design

[0030] Through the combined design of innovative structures such as movable connectors, turntables, switching starters, and hinged triggers, the automatic control of the locking and release of the layer tray is realized, which improves the flexibility and intelligence level of material management. At the same time, the coordinated design of the passive release mechanism and the rotating arm mechanism can efficiently and reliably complete the transfer of the layer tray between the shelf and the carrying component without adding an additional power source.

[0031] 2. Improve the level of intelligent management

[0032] Combining traditional shelf units with Internet of Things technology, real-time monitoring of material status and location through wireless modules and sensors realizes intelligent management and scheduling of materials, providing reliable material support for power projects.

[0033] 3. Improve work efficiency

[0034] The rotating arm mechanism can accurately and efficiently lift or insert the layer pallet into the shelf to achieve automatic vertical pick-up and placement; the enclosure and grabbing mechanism on the carrying component ensures stability during horizontal transportation and improves work efficiency.

[0035] 4. Comprehensiveness and integration

DETAILED DESCRIPTION

[0052] The present invention is further described below in conjunction with specific embodiments and all of Figures 1-9. More details are elaborated in the following description to facilitate a full understanding of the present invention, but the present invention is obviously capable of being implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0053] The present application uses specific words to describe the embodiments of the present application. For example, "one embodiment", "other embodiments", and / or "some embodiments" refer to a certain feature, structure or characteristic related to at least one embodiment of the present application. Therefore, it should be emphasized and noted that "one embodiment" or "other embodiments" or "some embodiments" mentioned twice or multiple times in different positions in this specification do not necessarily refer to the same embodiment. In addition, some features, structures or characteristics in one or more embodiments of the present application can be appropriately combined.

[0054] Example 1

[0055] Refer to all attached Figure 1-9 This application discloses an intelligent management system for power engineering materials based on Internet of Things technology. The system combines traditional shelf units with Internet of Things technology to achieve intelligent management of materials.

[0056] Reference Figure 2 , Figure 2 The figure shows a three-dimensional view of a combination of a single-row shelf unit 10 and a material conveying device 20 according to an embodiment of the present invention, which is suitable for an intelligent management system for power engineering materials based on the Internet of Things technology to be described later in the present invention. Figure 2As shown, the shelf unit 10 includes a plurality of shelf bodies 11 generally in the shape of a rectangular parallelepiped and arranged in a straight line standing on the ground, and a plurality of layer pallets 12 spaced and generally horizontally placed in each shelf body 11. The material conveying device 20 includes guide rails 21 fixedly installed on both sides of the upper edge of the shelf body 11 in the length direction, a carrying assembly 22 slidably matched with the guide rails 21 for carrying the layer pallets 12 for horizontal transportation, and a vertical pick-and-place assembly 23 having one end fixedly connected to the carrying assembly 22 and the other end extending vertically downward to near the ground. The plurality of layer pallets 12 can be extracted from the shelf body 11 by the vertical pick-and-place assembly 23 and handed over to the carrying assembly 22, or extracted from the carrying assembly 22 and placed in a suitable position of a shelf body 11.

[0057] The system combines traditional shelf units with the Internet of Things technology to achieve intelligent management of materials. Each shelf unit is equipped with sensors and wireless communication modules to monitor the storage status, location, quantity and other information of the goods in real time. At the same time, the carrying component 22 and the vertical pick-and-place component 23 are also integrated with the Internet of Things technology. The moving path of the goods can be accurately controlled through motors, encoders and other equipment, and the entire transportation process is monitored and dispatched in real time by the Internet of Things system. Through the application of the Internet of Things technology, the automation and intelligence level of material management is improved, providing efficient and reliable material support for power engineering.

[0058] The shelf body 11 is composed of four uprights 111 and a connection frame 112 or a plurality of connection beams arranged above and below. Figure 5 On the column 111, at least on the side facing the layer support plate 12, there are multiple connection structures 113 in an array that can receive or temporarily connect the layer support plate 12 in a range that basically covers the entire length.

[0059] The connection structure 113 can be a sunken table structure naturally formed at the connection between adjacent structures after a continuous combination of multiple inverted truncated cone-shaped structures. This design allows the layer support plate 12 to be firmly clamped on the connection structure 113, achieving reliable support and temporary storage of the layer support plate 12. At the same time, the inverted truncated cone shape also facilitates the vertical pick-and-place component 23 to accurately and efficiently clamp the layer support plate 12 into or take out the connection structure 113.

[0060] The connection structures 113 are distributed along the columns 111 in an array, so that the shelf body 11 can provide storage space for multiple layer pallets 12 in the height direction, thereby improving the storage density and the optional number of layer pallets 12, thereby improving the utilization rate. Overall, the modular design of the shelf body 11, combined with the innovative concept of the connection structure 113, lays a solid hardware foundation for efficient and orderly material storage and transportation.

[0061] Among them, refer to Figure 5-6The main body of the layer tray 12 has a plane shape that is consistent with the inner space of the shelf body 11 but is slightly smaller in size, so that the layer tray 12 can pass through the shelf body. A docking locking mechanism 120 is respectively provided at two edges of one set of opposite sides of the main body of the layer tray 12. The docking locking mechanism 120 includes:

[0062] 1) A movable connecting member 121 is hinged at the two corners below the layer support plate 12, and a torsional elastic member such as a torsion spring is provided at the hinge, so that the movable connecting member 121 is in a state of being connectable to the shelf body 11 when there is no external force (that is, the joint part is extended by rotation). At this time, the up and down degrees of freedom of the layer support plate 12 will be restricted by the four columns 111.

[0063] 2) A bottom plate 122 is provided at the center between the two movable connecting members 121 , and the bottom plate 122 is fixed below the layer support plate 12 .

[0064] 3) A turntable 123 is rotatably disposed on the bottom plate 122 .

[0065] 4) Each movable connecting member 121 is connected to the rotating disk 123 through a belt 124 or a rope, and is configured so that when the rotating disk 123 rotates a certain angle in one direction, the belt 124 will pull the movable connecting member 121 connected thereto to rotate, so that the movable connecting member 121 switches from a connectable state to a hidden state. At this time, the up and down movement of the layer support plate 12 is free.

[0066] 5) A threaded hole is provided at the center of the turntable 123, and a known ball screw transmission mechanism or the like can be used in the hole to increase the transmission efficiency and reduce the driving torque.

[0067] 6) A switching starter 125 is provided which is threadedly matched with the rotating disk 123. The free end of the switching starter 125 is away from the bottom plate. The free end is arranged to increase the contact area. It is preferred to arrange a structure with an annular surrounding groove.

[0068] 7) A hinge trigger 126 is provided, and the hinge trigger 126 includes a long strip body 261, which is parallel to the corresponding side of the layer support plate 12 after installation, and the range of movement is within the vertical projection range of the layer support plate 12. The hinge trigger 126 also includes a sleeve 262, the axis of which is parallel to the surface of the body 261 and maintains a certain horizontal and vertical distance from the length direction of the body 261, and the two are fixedly connected by a U-shaped or other open connection plate 263.

[0069] The hinge trigger 126 is hingedly connected through the hinge shaft 264 on the bottom plate 122, and the hinge shaft 264 is located close to the center of the layer support plate 12. A pressure rod 265 is fixed on the connecting plate 263, and the middle section of the pressure rod 265 contacts the switching starter 125. When a force is applied from bottom to top to the body 261 (the reverse direction is reset by a spring), the hinge trigger 126 rotates around the hinge shaft 264, and the pressure rod 265 presses the switching starter 125 to move downward, and the switching starter 125 drives the turntable 123 to rotate through the action of the thread.

[0070] When the rotating disk 123 rotates, the two belts 124 are driven to overcome the torsion force of the torsion spring in the movable connecting member 121, and the movable connecting member 121 is pulled to rotate to a hidden state. At this time, the up and down movement of the layer support plate 12 is free.

[0071] The hinged trigger 126 is cleverly designed and can efficiently and reliably control the locking and releasing of the layer support plate 12 through simple manual or mechanical drive. It is easy to operate and is the essence of the entire locking mechanism.

[0072] At this point, the layer tray 12 can be taken out of the shelf body 11 by the upwardly lifted vertical pick-and-place assembly 23. However, it is also necessary to consider the release action when the layer tray 12 is taken out of the carrying assembly 22 and placed in the shelf body 11.

[0073] Of course, multiple power sources such as motors, cylinders, etc. can be provided, and corresponding mechanisms can be added to drive the parking locking mechanism 120 to release, so as to place the layer tray 12 in the shelf body 11. However, that requires adding many power components and transmission mechanisms, which has high manufacturing and maintenance costs, and the overall system complexity will also increase, which is not very economical and practical.

[0074] Therefore, in the present invention, an ingenious and simple passive release mechanism is designed. Before introducing the passive release mechanism, it is necessary to first introduce the vertical pick-and-place assembly 23, because the work of the passive release mechanism needs to be completed in coordination with the components in the vertical pick-and-place assembly 23.

[0075] The vertical pick-and-place assembly 23 includes a linear conveying device 231 as a main body, and two rotating arm mechanisms 233 respectively installed at both ends of a moving beam 232 in the linear conveying device 231. The power and transmission part in the linear conveying device 231 adopts a common and mature mechanism in the known technology, such as a motor and a screw driving the moving beam, a synchronous belt and a motor driving the moving beam, etc. The rotating arm mechanism 233 receives and moves the layer support plate 12 by means of the linear motion of the moving beam 232.

[0076] The rotating arm mechanism 233 includes a working arm 234 , a motor 235 for driving the working arm 234 to rotate, and a transmission mechanism 236 for transmitting the motor power to the working arm 234 .

[0077] Reference Fig. 9 and Figure 9-1 The working arm 234 is in a horizontal L-shaped structure. The free end of the vertical part of the working arm 234 is upward, and the height should be greater than the height occupied by the upper connection frame 112 of the shelf body 11, so that when the layer pallet 12 is lifted, it can be completely pushed out of the shelf body 11, so that the carrying component 22 can grab it.

[0078] A rotating shaft 237 is fixedly arranged on the horizontal part of the working arm 234 at approximately the middle position close to one side of the moving beam 232. Both ends of the moving beam 232 are provided with rotating holes matching the rotating shaft 237, so that the horizontal part of the working arm 234 can be rotatably mounted on the moving beam 232. A shaft sleeve 238 is arranged at the free end of the horizontal part of the working arm 234.

[0079] The arm mechanism 233 is reasonably designed. Through the linear movement of the moving beam 232 and the rotation of the working arm 234, the layer tray 12 can be lifted or inserted accurately and efficiently from the shelf body 11. It is a key mechanism for realizing vertical access. In conjunction with the passive release mechanism, an integrated layer tray 12 access process can be completed.

[0080] The transmission mechanism 236 includes transmission gears 239 fixed at both ends of the moving beam 232. A pin 240 is fixedly arranged on the downward side of the transmission gear 239 near the outer ring and is sleeved with the shaft sleeve 238 of the working arm 234.

[0081] The main body of the motor 235 is also fixedly mounted on the moving beam 232, and its output shaft is mounted with a driving gear meshing with the transmission gear 239. Through the power output of the motor 235, the transmission gear 239 can rotate forward or reverse, thereby driving the pin shaft 240 to rotate forward or reverse.

[0082] The rotation of the pin 240 drives the working arm 234 to swing around the axis of the rotating shaft 237 to the inner or outer side of the projection below the layer support plate 12. This swinging motion enables the vertical part of the working arm 234 to enter the lower part of the layer support plate 12, contact with the hinge trigger 126 and apply force; or leave the lower part of the layer support plate 12 to adjust the upper and lower positions.

[0083] The transmission mechanism 236 has a compact design and a simple structure, and can efficiently and reliably transmit the power of the motor 235 to the working arm 234, so as to achieve the precise swing of the working arm 234, and is the core driving device of the entire rotating arm mechanism 233. It cooperates with the working arm 234, the hinge trigger 126 and other components to complete the vertical pick-up and placement action of the layer tray 12.

[0084] Further references Figure 3The transmission gear 239 is designed to be partially located inside the linear conveying device 231, and the transmission gear 239 is divided into a central fixed part and a gear ring rotating around the central part. The gear ring can be a half-circle tooth. In this way, it is necessary to open a movable groove on the main body of the linear conveying device 231 for the transmission gear 239 to move up and down. The purpose of this design is to make the structure more compact.

[0085] Returning to the passive release mechanism 30, refer to Figure 6-9 , which includes a positioning column 31 fixed in the layer support plate 12 and located within the rotation range of the working arm 234. A guide release hole 32 is opened on the body 261 of the hinge trigger 126 at a position corresponding to the positioning column 31. The guide release hole 32 can be a waist hole or a U-shaped hole with one side open. The size of the hole should be larger than the size of the vertical part of the working arm 234 (or a section of the front end of the vertical part) to avoid interference when the body 261 swings.

[0086] The height of the positioning column 31 is set to be equal to or slightly lower than the side of the body 261 facing away from the layer support plate 12 when the body 261 is closest to the layer support plate 12. In this way, by controlling the position of the working arm 234 in the body 261, the working state of the hinge trigger 126 can be switched.

[0087] For example, refer to Figure 6 When the vertical part of the working arm 234 is located on the surface of the body 261, the upward movement of the moving beam 232 can pull the movable connecting member 121 to contract, thereby locking the layer support plate 12. At this time, if the working arm 234 swings, refer to Figure 8 , the vertical part will enter the guide release hole 32 and abut the positioning column 31. In this case, although the position of the layer support plate 12 remains unchanged, the guide release hole 32 provides a reset space for the reset spring in the switching starter 125.

[0088] Therefore, by swinging the working arm 234 around the rotating shaft 237, the pressure rod 265 of the hinge trigger 126 can be accurately and controllably pushed or released, thereby driving the parking lock mechanism 120 to lock or unlock. The passive release mechanism 30 is organically combined with the rotating arm mechanism 233, and the reliable transfer of the layer tray 12 between the shelf body 11 and the carrying assembly 22 is efficiently achieved without adding a power source. This innovative design has the advantages of flexibility, economy and practicality.

[0089] Furthermore, a barrier 221 is provided in the carrying assembly 22 to better limit and protect the position and posture stability of the materials in the layer pallet 12 during horizontal transportation, thereby preventing the materials from being displaced or tilted.

[0090] Furthermore, a claw-type grabbing mechanism 222 is provided in the carrier assembly 22, which may be a pneumatic claw hand or an electric winch-type grabbing mechanism in the prior art. The grabbing mechanism 222 is used to reliably clamp the layer support plate 12 to ensure its synchronous movement with the carrier assembly 22.

[0091] Further, refer to Figure 1 At both ends of the guide rail 21 of the shelf unit 10 in the extension direction, there is a space area beyond the shelf body 11. The lower space of the beyond part can be used to set up transfer transportation tools such as automatic guided vehicles (AGVs) or rail-type shuttles, so as to achieve seamless connection with a larger range of logistics systems.

[0092] In the upper space of the overtaking part, facilities such as auxiliary operation tables and storage cabinets can also be installed to facilitate manual auxiliary operation. At the same time, these overtaking areas can also be used to set up supporting equipment such as control system cabinets and power supplies.

[0093] Through the above-mentioned perfect design, the entire intelligent management system of power engineering materials not only achieves a high degree of automation in the core shelf area, but also efficiently and seamlessly connects with external systems. At the same time, it also reserves operating space for necessary manual intervention, reflecting a high degree of comprehensiveness and integration, and truly achieving intelligent and efficient management.

[0094] Example 2

[0095] This embodiment takes the transport distribution box as an example to illustrate the application of the intelligent management system of power engineering materials based on the Internet of Things technology.

[0096] like Figure 3 As shown, the distribution box 001 is stored in the shelf body 11 as the material in this embodiment. A plurality of distribution boxes 001 are arranged on the layer support plate 12.

[0097] RFID tags are provided on the appropriate surfaces of the distribution box 001, and the RFID tags contain the unique coding information of the distribution box. RFID readers are arranged at a certain interval on the columns 111 of the shelf area, and the specific storage location of each distribution box can be accurately known through continuous scanning and identification.

[0098] In addition, weight sensors are provided at the four bottom corners of the layer support plate 12 to detect the weight of the distribution box placed on the layer plate and associate the weight data with the RFID information. If the weight is abnormal, it can be judged as an abnormal situation such as missing parts or overloading.

[0099] All RFID readers and weight sensors are connected to the edge gateway of the Internet of Things system, and the edge gateway uploads the collected data to the server of the management platform in real time via the wireless network.

[0100] On the server side, the coding, location, weight and other information of all distribution boxes are accurately modeled and displayed on a visual management interface. Managers can review the status of materials based on real-time data, and can also formulate material storage plans and send them to the site for execution.

[0101] When a batch of distribution boxes needs to be taken out from the warehouse, the management system will guide the robot car to automatically drive to the target shelf area based on the location information, and accurately take out the target layer pallet 12 through the rotating arm mechanism and passive release mechanism introduced above, and then the carrying component 22 will transport it to the collection and distribution operation area.

[0102] From the above process, we can see that through the Internet of Things technology and intelligent control, the whole process of power materials has been made "visible, traceable, and commandable". It has greatly improved management efficiency, reduced manpower and logistics costs, ensured the optimal configuration of power engineering materials, and is a strong support for the construction of smart power.
