[0070] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0071] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0072] The present application provides a lifting device for server cabinets, which aims to solve the problem of high intensity of manual lifting operations and eliminate the problem of collapse caused by imbalance; and solve the problem of low operating efficiency and high operating safety risks of other simple equipment.

[0073] Please refer to FIG. 1 , which is a schematic diagram of the structure of a server cabinet lifting device provided in an embodiment of the present application.

[0074] In FIG1 , the coordinate axes are marked, and the directions indicated by the coordinate axes are consistent with the directions described in the present application. The coordinate axes X, Y, and Z are perpendicular to each other. The coordinate axis X represents the first direction, which is also the length direction and the left-right direction. The coordinate axis Y represents the second direction, which is also the width direction and the front-back direction. The coordinate axis Z represents the third direction, which is also the height direction and the up-down direction.

[0075] In the first specific implementation manner, the server cabinet lifting equipment provided by the embodiment of the present application mainly includes a box body 1 and a lifting device 2, and the box body 1 can be moved to the use area as needed; the lifting device 2 is arranged on the box body 1, and the lifting device 2 is used to lift the server loaded into the box body 1 to a designated position along a third direction; the lifting device 2 includes a driving mechanism 21 and a lifting plate 22, and the driving mechanism 21 is arranged on the box body 1; the lifting plate 22 is arranged on the box body 1, and the lifting plate 22 is connected to the driving mechanism 21, and the lifting plate 22 is used to realize the lifting movement along the third direction under the drive of the driving mechanism 21.

[0076] In traditional server rack operations, manual lifting and simple lifting equipment have the disadvantages of high labor intensity, high operating risks and low efficiency. Especially in the small space of the data center, these methods are not only difficult to meet the growing demand for server installation, but also easily cause safety accidents, causing personal injury or equipment damage. In response to these technical problems and defects, the server cabinet lifting equipment provided in this application provides a more efficient, safe and easy-to-operate solution through innovative design.

[0077] The core of the lifting device lies in the combination of its box 1 and the lifting device 2. The mobility of the box 1 enables the equipment to be flexibly pushed to any required area, greatly improving the flexibility and adaptability of the operation. The design of the lifting device 2 allows the server to be lifted and lowered in the vertical direction, which is achieved by the coordinated work of the driving mechanism 21 and the lifting plate 22. The driving mechanism 21 is built into the box 1, and through precise control, it can drive the lifting plate 22 to move in the third direction, such as moving the lifting plate 22 vertically, so as to smoothly lift the server to the specified position.

[0078] This design effectively reduces the physical labor of operators, because there is no need to manually lift servers weighing tens or even hundreds of kilograms. At the same time, through mechanized lifting control, the safety risks caused by improper manual operation are greatly reduced. In addition, the precise coordination between the lifting plate 22 and the driving mechanism 21 ensures the stability of the server during the rising or falling process, avoids the possibility of tilting or collapse, and further improves the safety of the operation.

[0079] Combined with the above structure and process description, it can be seen that the server cabinet lifting equipment has at least the following beneficial effects: the server cabinet lifting equipment effectively solves the problems of high labor intensity, low safety and low efficiency existing in traditional manual lifting and simple lifting equipment in server rack operations, and realizes fast, safe and precise lifting of the server, improves work efficiency and reduces operational risks.

[0080] When using the lifting device for the server cabinet, first ensure that the cabinet 1 is moved to the use area of ​​the server cabinet operation. Next, place the server in the cabinet 1, and the lifting device 2 is located in the cabinet 1, ready for lifting operation. The lifting device 2 is mainly composed of a driving mechanism 21 and a lifting plate 22, wherein the driving mechanism 21 is responsible for providing power, and the lifting plate 22 is the part that directly contacts and lifts the server.

[0081] Before the operation begins, it is necessary to check whether the lifting plate 22 is properly connected to the driving mechanism 21 to ensure that the connection between them is firm, so as to facilitate stability and safety during the lifting process. Then, according to the weight and size of the server, the parameter settings of the driving mechanism 21 are adjusted to meet the lifting requirements of different servers.

[0082] After starting the driving mechanism 21, the lifting plate 22 will begin to rise along the third direction, i.e., move vertically upward, and lift the server to a desired height stably. In this process, the operator can monitor the lifting state to ensure the stability of the lifting process and the safety of the server.

[0083] When the server is lifted to a designated position close to the cabinet, the operator can take the server out of the lifting plate and place the server firmly in the cabinet to achieve the purpose of mounting the server on the cabinet.

[0084] After use, the lifting plate 22 needs to be lowered to the lowest position, the driving mechanism 21 needs to be turned off, and the box 1 needs to be removed from the use area according to the operating procedures, and necessary equipment inspection and maintenance needs to be performed to ensure the reliability and safety of the equipment when it is used next time. Through this operation mode, the lifting equipment for server cabinets not only improves the operating efficiency, but also significantly reduces the operating risks, and realizes the fast, safe and accurate lifting of the server.

[0085] It should be noted that this embodiment does not limit the driving principle and structural form of the driving mechanism 21 in the lifting device 2. The driving mechanism 21 can adopt electric, pneumatic and hydraulic driving structures, all of which should belong to the description scope of this embodiment.

[0086] For example, the driving mechanism 21 may be an electric telescopic rod, through which the lifting plate 22 can be lifted and lowered. The driving mechanism 21 may also be a combination of a motor and a transmission structure, which can also lift and lower the lifting plate 22. Therefore, driving mechanisms 21 with different driving principles and structural forms should all fall within the scope of the present application.

[0087] Please refer to FIG. 2 , which is a cross-sectional structural diagram 1 of a server cabinet lifting device provided in an embodiment of the present application.

[0088] As shown in FIG. 2 , in a specific implementation manner, the driving mechanism 21 provided in the embodiment of the present application includes:

[0089] A driving assembly 211 is provided in the housing 1;

[0090] The rotating shaft 212 is provided in the housing 1, and the rotating shaft 212 is used to rotate around the central axis of the rotating shaft 212 under the drive of the driving assembly 211;

[0091] The cable 213 has a first end fixedly connected to the rotating shaft 212 and a second end fixedly connected to the lifting plate 22 .

[0092] In this embodiment, the core component of the server cabinet lifting device is the driving mechanism 21, which plays a key role in realizing the lifting movement of the lifting plate 22. The driving mechanism 21 is composed of several key components: a driving assembly 211, a rotating shaft 212 and a cable 213.

[0093] The driving assembly 211 is the power source of the driving mechanism 21, and is arranged in the housing 1, and is responsible for providing the required power and control signals. The operation of the driving assembly 211 can drive the rotating shaft 212 directly or indirectly connected thereto.

[0094] The rotating shaft 212 is a mechanical component in the driving mechanism 21, and is also disposed in the housing 1. The design of the rotating shaft 212 allows it to rotate around its own central axis when driven by the driving assembly 211. This rotational motion is a key mechanical action to achieve the lifting of the lifting plate 22.

[0095] The cable 213 is a mechanical element connecting the rotating shaft 212 and the lifting plate 22, and one end of the cable 213 is fixedly connected to the rotating shaft 212 to ensure that the rotation of the rotating shaft 212 can be directly transmitted to the cable 213. The other end of the cable 213 is fixedly connected to the lifting plate 22, so that when the rotating shaft 212 rotates, the cable 213 will pull the lifting plate 22 to perform corresponding lifting movements, thereby realizing the lifting operation of the server.

[0096] When in use, the drive mechanism 21 is started, and the drive assembly 211 starts to work, providing the required power for the entire lifting system. This power is transmitted through the connection with the rotating shaft 212, so that the rotating shaft 212 rotates around its central axis. The rotation of the rotating shaft 212 is the key to achieving the lifting action, because it is directly connected to the lifting plate 22 through the cable 213.

[0097] As the rotating shaft 212 continues to rotate, the cable 213 begins to wind or loosen, and this process depends on the rotation direction of the rotating shaft 212 and the winding method of the cable 213. This change of the cable 213 causes the lifting plate 22 to move vertically. If the rotation of the rotating shaft 212 causes the cable 213 to wind, the lifting plate 22 will rise; on the contrary, if the rotation of the rotating shaft 212 causes the cable 213 to loosen, the lifting plate 22 will fall.

[0098] The design of the lifting plate 22 ensures that it can stably contact the server and provide stable support during the lifting process. This design avoids the server from tilting or sliding during the lifting process, ensuring the safety of the server and the reliability of operation.

[0099] In order to accurately control the lifting position of the lifting plate 22, the driving mechanism 21 may include some control mechanisms, such as limit switches or position sensors, which can monitor the current position of the lifting plate 22 and ensure that it accurately reaches the preset height. In addition, the control system may also have emergency stop and manual fine-tuning functions to quickly respond or make fine adjustments when necessary.

[0100] Optionally, the cable 213 is a steel cable. In the second direction, the cable 213 is fixedly connected to the midpoint of the rotating shaft 212.

[0101] Please continue to refer to FIG. 2 . In some embodiments, the box 1 includes:

[0102] The box-shaped body 11 has a rotating shaft 212 disposed therein;

[0103] The support frame 12 is provided on the box-shaped body 11, and the support frame 12 is provided with a support member 13, and the support member 13 is located above the lifting plate 22 in the third direction;

[0104] The cable 213 is hung on the support member 13 .

[0105] In this embodiment, the box 1 is the basic structure of the server cabinet lifting device, which provides support and accommodation space for the entire system. The box body 11 is the main part of the box 1, and its internal space is used to set the shaft 212, which is a key component of the driving mechanism 21, responsible for supporting the shaft and allowing it to rotate, thereby driving the cable 213.

[0106] The support frame 12 is a structure fixed on the box-shaped body 11, and its main function is to provide additional support for the rotating shaft 212 and work together with the rotating shaft 212 to realize the lifting movement of the lifting plate 22. The support frame 12 is provided with support members 13, which are located above the lifting plate 22, that is, higher than the lifting plate 22 in the vertical direction.

[0107] One end of the cable 213 is fixedly connected to the rotating shaft 212, and the other end of the cable 213 is fixedly connected to the lifting plate 22 after being hung and passed through the support member 13. The function of the support member 13 is to provide a support point for the cable 213 to form a fixed pulley system. Since the cable 213 passes through the support member 13 to form a fixed pulley, the rotation of the rotating shaft 212 will cause the cable 213 to drive the lifting plate 22 to rise and fall. This form of fixed pulley movement allows the rotation of the rotating shaft 212 to be directly converted into the vertical movement of the lifting plate 22.

[0108] The advantage of this design is that it simplifies the mechanical structure, while taking advantage of the mechanical advantage of the fixed pulley, reducing the wear of the cable 213 and making the lifting plate 22 more stable. Through the arrangement of the support frame 12 and the support member 13, the tension of the cable 213 is effectively controlled, ensuring the stability and reliability of the entire lifting system. Therefore, the structural design of the box 1 not only provides mechanical support, but also realizes effective control of the lifting plate 22 through the fixed pulley system, ensuring the safety and accuracy of the server cabinet operation.

[0109] Optionally, the support member 13 is a bearing.

[0110] Please refer to FIG. 4 , which is a second cross-sectional structural diagram of the server cabinet lifting device provided in an embodiment of the present application.

[0111] As shown in FIG. 4 , in a specific implementation manner, the box 1 provided in the embodiment of the present application further includes:

[0112] The mounting platform 14 is provided on the box-shaped body 11;

[0113] The driving assembly 211 includes:

[0114] The motor 2111 is disposed on the mounting platform 14 and is located outside the box-shaped body 11;

[0115] The rotating shaft 212 is connected to the output end of the motor 2111 .

[0116] In this embodiment, the design of the box body 1 is further extended to include a mounting platform 14, which is a structural component for fixing and supporting the drive assembly 211. The mounting platform 14 is arranged on the box-shaped body 11, providing a stable platform for the drive assembly 211. This layout allows the drive assembly 211 to function under the protection and enclosure of the box-shaped body 11, while ensuring that the installation position of the motor 2111 is both stable and easy to maintain.

[0117] The driving assembly 211 is the core part of the driving mechanism 21, and it includes a motor 2111. The motor 2111 is mounted on the mounting platform 14 and is located outside the box-shaped body 11. Such a layout is helpful for heat dissipation and maintenance of the motor 2111, and it is also possible to facilitate the connection of the motor 2111 with an external power source.

[0118] The key mechanical connection point is that the shaft 212 is connected to the output end of the motor 2111. This means that the rotational power of the motor 2111 can be directly transmitted to the shaft 212, thereby driving the entire lifting system. This direct connection method improves the efficiency of power transmission and ensures that the lifting plate 22 can be lifted and lowered smoothly and accurately.

[0119] Through this design, the motor 2111 not only provides the necessary power source for the lifting device, but also ensures the stability of the motor and facilitates access to the external control system through the setting of the mounting platform 14. The design of the entire drive assembly 211 is compact and efficient, providing a reliable and easy-to-maintain power system for the lifting device for the server cabinet.

[0120] Please refer to FIG. 3 , which is a schematic diagram of the disassembly of the support frame in FIG. 2 .

[0123] A pair of connecting plates 122, provided on the top plate 121;

[0124] The extension plate 123 is disposed on the box-shaped body 11 , and is connected to the top plate 121 .

[0125] The support member 13 is disposed on a pair of connecting plates 122 .

[0126] In this embodiment, the top plate 121 is a component of the support frame 12, which serves as a platform and provides connection points for other components. A pair of connecting plates 122 are provided on the top plate 121, and their main function is to set the support member 13. The support member 13 is a key component of the support frame 12, which is responsible for providing a support point for the cable 213 to ensure the stable movement of the cable 213.

[0127] The extension plate 123 is disposed on the box-shaped body 11 and connected to the top plate 121. The provision of the extension plate 123 allows the support frame 12 to be spatially expanded as required to accommodate servers of different sizes or different lifting requirements.

[0128] In this design, the support frame 12 provides an adjustable and stable support structure through the coordinated action of the top plate 121, the connecting plate 122 and the extension plate 123. The support member 13 provided on the connecting plate 122 ensures that the cable 213 can be effectively connected to the lifting plate 22 to achieve smooth lifting and lowering movement of the lifting plate 22. This structural design not only enhances the stability and adaptability of the entire lifting device, but also improves the safety and convenience of operation.

[0129] Please continue to refer to FIG. 3 . In some embodiments, the extension plate 123 includes at least one extension unit 1231 . The extension unit 1231 is provided with a clamping groove and a clamping block at both ends in the third direction.

Each extension unit 1231 is provided with a clamping groove and a clamping block at both ends in the vertical direction (i.e., the third direction). This design allows that when more than two extension units 1231 are used, they can cooperate with each other through the clamping grooves and clamping blocks at their ends, and be vertically stacked and connected one by one, so that the total height of the extension plate 123 can be increased as required to adapt to servers or cabinets of different heights.

[0133] In addition, a snap-in block is also provided on the top plate 121. The extension plate 123 cooperates with the snap-in block on the top plate 121 through the snap-in groove on the extension unit 1231 to achieve connection between the two. This connection method not only ensures the stability of the extension plate 123 and the support frame 12, but also provides a simple way to adjust or assemble the height of the support frame 12 to meet the lifting requirements in different scenarios.

[0134] The advantage of this design is its flexibility and scalability, which allows the support frame 12 to be easily adjusted to accommodate operations on server cabinets of different heights while maintaining structural stability and ease of operation. Through the cooperation of the card slot and the card block, quick disassembly and assembly can be achieved, thereby improving the practicality and efficiency of the entire lifting device.

[0135] For example, in Figure 3, the snap-in groove on the upper side of the first extension monomer 1231 is a first snap-in groove 12311, which can cooperate with the snap-in block on the lower side of the top plate 121; the snap-in block on the lower side of the second extension monomer 1231 is a second snap-in block 12312, which can cooperate with the snap-in groove on the upper side of the box-shaped body 11.

[0136] Please continue to refer to FIG. 4 . In some embodiments, the rotating shaft 212 is extended in the second direction. The number of the rotating shaft 212 and the cable 213 is two groups. The two groups of rotating shafts 212 and cables 213 are spaced apart along the first direction.

[0137] The first end of the lifting plate 22 in the first direction is connected to the first group of cables 213 , and the second end of the lifting plate 22 in the first direction is connected to the second group of cables 213 .

[0138] In this embodiment, the shaft 212 and the cable 213 are provided to achieve stable lifting and lowering movement of the lifting plate 22. The shaft 212 extends in a second direction perpendicular to the lifting direction, and is provided in two groups, and the two groups of shafts 212 and corresponding cables 213 are spaced apart along a first direction perpendicular to the lifting direction.

[0139] This design allows the lifting plate 22 to be connected to the rotating shaft 212 through two sets of cables 213, thereby achieving a more balanced and stable lifting movement. The first end of the lifting plate 22 in the first direction is connected to the first set of cables 213, and the second end in the first direction is connected to the second set of cables 213. This connection method allows the two sets of cables 213 to be wound or released on the corresponding rotating shaft 212 respectively, and work together to control the vertical movement of the lifting plate 22.

[0140] In this way, the rotational power of the shaft 212 is transmitted through the cable 213, so that the lifting plate 22 can be smoothly raised or lowered. This arrangement not only improves the load capacity and stability of the lifting equipment, but also reduces the safety risks caused by the failure of a single cable or shaft by dispersing the force. In addition, the design of two sets of cables 213 and the shaft 212 can also provide more precise control when necessary to meet the needs of server cabinets of different weights or sizes.

[0141] Optionally, the two groups of rotating shafts 212 are symmetrically arranged.

[0142] Please continue to refer to FIG. 4 , in some embodiments, the driving component 211 includes:

[0143] The motor 2111 is disposed in the box 1, and the output end of the motor 2111 is connected to the first set of rotating shafts 212;

[0144] A driving sprocket 2112 is disposed on the first set of rotating shafts 212;

[0145] The driven sprocket 2113 is disposed on the second set of rotating shafts 212;

[0146] The chain 2114 is wound around the driving sprocket 2112 and the driven sprocket 2113 to achieve synchronous movement of the second group of rotating shafts 212 when the motor 2111 drives the first group of rotating shafts 212 .

[0147] In this embodiment, the driving component 211 is the core component of the lifting device for the server cabinet. It transmits the power generated by the motor 2111 to the rotating shaft 212 through a series of precise mechanical transmission structures, thereby realizing the lifting movement of the lifting plate 22.

[0148] The motor 2111 is installed in the housing 1, and its output end is connected to the first set of rotating shafts 212. The selection and design of the motor 2111 should ensure that it can provide enough torque to drive the entire lifting system while maintaining the stability and accuracy of the operation.

[0149] The driving sprocket 2112 is installed on the first group of rotating shafts 212 connected to the motor 2111. When the motor 2111 starts, it will drive the driving sprocket 2112 to rotate, and then transfer power to the driven sprocket 2113 through the chain 2114.

[0150] The driven sprocket 2113 is mounted on the second set of rotating shafts 212 and is connected to the driving sprocket 2112 via a chain 2114. The configuration of the sprocket and the chain allows the two sets of rotating shafts 212 to rotate synchronously, thereby ensuring the stable lifting of the lifting plate 22.

[0151] The chain 2114 is a transmission element connecting the driving sprocket 2112 and the driven sprocket 2113. It is wound between the two sprockets to evenly distribute the power of the motor 2111 to the two sets of rotating shafts 212. This design not only improves the stability and reliability of the system, but also ensures the balance of the lifting plate 22 during the lifting process by synchronizing the movement of the two sets of rotating shafts 212.

[0152] Through this design, the drive component 211 realizes efficient power transmission between the motor 2111 and the rotating shaft 212, providing a stable and reliable driving method for the lifting equipment for the server cabinet, ensuring that the lifting plate 22 can be lifted and lowered smoothly and accurately.

[0153] Optionally, the box-shaped body 11 is provided with a connecting groove 17 , and the chain 2114 is arranged in the connecting groove 17 .

[0154] Please continue to refer to Figure 2. In some embodiments, the box 1 includes a support frame 12 provided with a support member 13. The number of the support frames 12 is two groups, and the two groups of support frames 12 are spaced apart along the first direction. The first group of cables 213 is hung on the support member 13 of the first group of support frames 12, and the second group of cables 213 is hung on the support member 13 of the second group of support frames 12.

[0155] In this embodiment, the design of the box 1 further enhances the stability and practicality of the lifting device. The box 1 comprises two groups of support frames 12, on which support members 13 are arranged at intervals along the first direction of the lifting device.

[0156] Each set of support frames 12 is equipped with support members 13, which are fixing points for cables 213. The first set of cables 213 is hung on the support members 13 of the first set of support frames 12, while the second set of cables 213 is hung on the support members 13 of the second set of support frames 12. This design allows the cables 213 to be fixed at two support points at different heights, thereby providing a more stable support structure.

[0157] Through this configuration, the two sets of support frames 12 and their support members 13 can evenly distribute the load on the lifting plate 22, reduce the pressure on a single support point, and reduce the risk of structural fatigue or damage caused by uneven load. At the same time, this design also allows the position of the lifting plate 22 to be finely adjusted to accommodate servers or cabinets of different heights, thereby improving the flexibility and adaptability of the lifting equipment.

[0158] In addition, the design of two sets of support frames 12 also helps to improve the safety of the lifting equipment. During the lifting process, even if one set of cables fails, the other set of cables can still provide necessary support to prevent the lifting plate 22 and the server from accidentally falling, thereby ensuring the safety of the operation. This redundant design reflects the emphasis on equipment stability and safety.

[0159] In some embodiments, wheels 15 are provided on the lower side of the box body 1 in the third direction.

[0160] In this embodiment, the design of the box 1 takes into account the convenience of movement, and the box 1 is equipped with wheels 15. These wheels 15 are installed on the lower side of the box 1, so that the entire lifting device can be easily moved on a flat surface.

[0161] The design of wheels 15 not only improves the mobility of the equipment, but also allows operators to quickly adjust the position of the equipment when needed to adapt to different work scenarios or specific requirements of server cabinet operations. In addition, wheels 15 can also reduce friction with the ground during movement, reducing labor intensity and potential ground damage when moving the equipment.

[0162] By providing wheels 15 on the lower side of the box 1, the overall design of the lifting device becomes more user-friendly and efficient. This design allows the device to be flexibly operated in a narrow space in a data center or server storage area, improving operating efficiency, and also allows the device to be conveniently stored or moved to other locations when not in use.

[0163] In some embodiments, the lifting plate 22 is provided with a ball 221 .

[0164] In this embodiment, the lifting plate 22 is specially designed with balls 221, which can rotate freely on the lifting plate 22. The main function of the balls 221 is to reduce the friction between the server and the lifting plate 22 during the placement or movement of the server, thereby improving the efficiency of the server loading process and reducing the labor intensity of the operator during the handling process.

[0165] In some embodiments, the box body 1 is provided with a slide groove 16 , and the slide groove 16 is extended in the third direction; the lifting plate 22 is provided with a sliding wheel 222 , and the sliding wheel 222 cooperates with the slide groove 16 .

[0166] In this embodiment, the design of the box body 1 includes slide grooves 16, which are extended in the vertical direction (the third direction). The slide grooves 16 exist to cooperate with the sliding wheels 222 on the lifting plate 22. The lifting plate 22 is equipped with sliding wheels 222, which can slide smoothly along the slide grooves 16.

[0167] This design allows the lifting plate 22 to be precisely positioned and moved along the vertical direction inside the box 1. The cooperation between the sliding wheel 222 and the slide slot 16 ensures that the lifting plate 22 can be lifted and lowered smoothly.

[0168] By providing the chute 16 in the box 1 and cooperating with the sliding wheel 222 on the lifting plate 22, the operation of the entire lifting device is more flexible and the accuracy of the lifting process is improved. In addition, the rolling of the sliding wheel 222 in the chute 16 reduces friction, helps to reduce energy consumption, improves the working efficiency of the device, and reduces wear caused by friction, thereby extending the service life of the device.

[0169] In addition, the cooperation between the slide groove 16 and the sliding wheel 222 can reduce the speed of the lifting plate 22 when it falls.

[0170] Please refer to FIG. 5 , which is a schematic diagram of the structure of the anti-falling device provided in an embodiment of the present application.

[0171] As shown in FIG5 , in a specific implementation manner, the server cabinet lifting device provided by the embodiment of the present application further includes:

[0172] The anti-falling device 3 is arranged on the box body 1, and is used to prevent the lifting plate 22 from falling along the third direction.

[0173] In this embodiment, the lifting device for the server cabinet has an important safety feature, namely, the anti-falling device 3. The anti-falling device 3 is designed and installed in the box 1. Its main function is to prevent the lifting plate 22 and the server thereon from falling in the vertical direction (third direction) when an accident occurs, such as the cable 213 breaking or the driving mechanism 21 failing, so as to protect the server from damage and ensure the safety of personnel and equipment.

[0174] The anti-fall device 3 usually includes a series of mechanical structures and control mechanisms, which can be automatically triggered when a falling action is detected, and quickly lock and fix the lifting plate 22 to prevent it from falling further. The design of this device is crucial because it provides a backup safety measure that can ensure the safety of the server even if the main lifting and control system fails.

[0175] By integrating the anti-fall device 3, the server cabinet lifting equipment not only improves the efficiency and convenience of the operation, but more importantly, improves the safety of the entire operation process. The addition of this safety feature allows operators to perform server cabinet operations more confidently, reducing concerns about unexpected situations, and reflects a high sense of responsibility for the safety of operators and equipment.

[0176] In some embodiments, the box body 1 includes a box-shaped body 11 provided with movable grooves 111, the number of the movable grooves 111 is two groups, and the two groups of movable grooves 111 are spaced apart in the first direction; the number of the anti-falling devices 3 is two groups, and the two groups of anti-falling devices 3 are spaced apart along the first direction; each group of anti-falling devices 3 includes:

[0177] The extrusion block 31 is disposed in the movable groove 111, and the extrusion block 31 can move along the first direction;

[0178] The elastic member 32 is disposed in the movable groove 111, the free end of the elastic member 32 is connected to the extrusion block 31, and the elastic member 32 can be compressed and stretched along the first direction;

[0179] The limiting block 33 is disposed in the movable groove 111, and the limiting block 33 can move along the first direction. The limiting block 33 is located at the lower side of the extrusion block 31 in the third direction;

[0180] A slider 34 is disposed on the limiting block 33, and the slider 34 can move along a third direction;

[0181] A connecting rod 35, a first end of which is rotatably connected to the extrusion block 31, and a second end of which is rotatably connected to the limiting block 33, and the connecting rod 35 is provided with a sliding groove 351;

[0182] The center rod 36 is disposed in the movable groove 111, and the center rod 36 passes through the sliding groove 351;

[0183] When the lifting plate 22 falls to the extrusion block 31 along the third direction, the lifting plate 22 pushes the extrusion block 31, so that the extrusion block 31 moves toward the inside of the movable groove 111 in the first direction, and the elastic member 32 is compressed. At the same time, the connecting rod 35 rotates around the center rod 36, and the connecting rod 35 drives the slider 34 to move, so that the limiting block 33 moves toward the outside of the movable groove 111 in the first direction. The limiting block 33 is located below the lifting plate 22 in the third direction, and the lifting plate 22 is prevented from falling along the third direction by the limiting block 33.

[0184] Optionally, the elastic member 32 is a spring. The two groups of movable grooves 111 are symmetrically distributed.

[0185] Furthermore, the anti-fall device 3 is further improved and its functions are expanded to enhance its safety and reliability.

[0186] Optionally, an automatic detection and response system is provided in the anti-fall device 3, which provides an additional layer of safety for the lifting equipment for the server cabinet. The automatic detection and response system includes a speed sensor and a displacement sensor. The speed sensor is responsible for monitoring the lifting speed of the lifting plate 22 to ensure that it operates within a preset safe speed range. The displacement sensor is used to detect the vertical position change of the lifting plate 22 to identify any abnormal displacement.

[0187] In terms of the installation position, the speed sensor is installed on the cable 213 between the lifting plate 22 and the driving mechanism 21 to accurately measure the pulling speed of the cable. The displacement sensor is installed on both sides of the box 1 to monitor the vertical position of the lifting plate 22. This layout ensures that the sensor can provide accurate feedback during the lifting process.

[0188] The data from these sensors are transmitted in real time to the control unit, which has built-in advanced algorithms that can quickly analyze the sensor data. Once an abnormal peak in speed or displacement outside the normal range is detected, the system will automatically trigger the preset safety protocol.

[0189] Combined with the original application solution, the control unit works closely with the motor 2111 of the driving mechanism 21 to quickly stop the movement of the lifting plate 22 by adjusting the output of the motor or directly cutting off the power supply. In addition, the system can also activate the anti-fall device 3 to ensure that the lifting plate 22 and the server thereon are fixed in time to prevent any risk of falling.

[0190] In addition, the automatic detection and response system can not only monitor the status of the lifting plate 22 in real time, but also work together with other safety devices on the box body 1 when necessary to form a comprehensive safety network to ensure the safety and reliability of the entire lifting process.

[0191] Optionally, a load identification and adjustment system is provided in the anti-fall device 3 to further improve the adaptability and safety of the lifting device. The design of the system allows the device to automatically adjust its operating parameters according to the weight of the load, ensuring that servers of different weights can be properly supported and protected.

[0192] The core of the system is a high-precision load sensor installed under the lifting plate 22 or on the cable 213 connected to the lifting plate 22. When the server is placed on the lifting plate 22, the load sensor can measure and transmit the weight data of the load to the control unit in real time.

[0193] After receiving the load weight data, the control unit automatically adjusts the power output of the drive mechanism 21, as well as the sensitivity and braking force of the anti-fall device 3 according to the preset algorithm and parameters. For example, if a heavier load is detected, the system will increase the output torque of the drive mechanism 21 to ensure a smooth lifting process, and increase the preload of the anti-fall device 3 to provide a stronger braking force.

[0194] In the original technical solution, the anti-fall device 3 already has the basic anti-fall function. Now, by introducing the load identification and adjustment system, the function of the anti-fall device 3 has been expanded and optimized. The control unit is combined with the original drive mechanism 21 and the motor 2111 to achieve more intelligent operation. This intelligent adjustment not only improves the working efficiency of the lifting equipment, but also enhances the adaptability to different load conditions and ensures the safety of operation.

[0195] In actual operation, when the operator places the server on the lifting plate 22, the load sensor immediately starts working and transmits data to the control unit. The control unit quickly calculates and adjusts relevant parameters to ensure that the anti-fall device 3 has been adjusted to the optimal state according to the weight of the load before the drive mechanism 21 is started. In this way, no matter how the weight of the server changes, the lifting equipment can provide stable and reliable support.

[0196] Through the setting of this load identification and adjustment system, the server cabinet lifting equipment not only improves its intelligence level, but also provides users with a safer and more convenient operation experience.

[0197] In a specific implementation, the use process of the server cabinet lifting device is described as follows.

[0198] First, adjust the height of the equipment according to the required height of the upper cabinet, install the same number of extension plates 123 on the left and right, use the self-contained clamping blocks and clamping grooves to accumulate the height, and install the upper part together with the top plate 121. At the same time, adjust the length of the cable 213 to meet the lifting height requirements. Then push the equipment near the server and place the server on the ball 221 of the lifting plate 22 in the box-shaped body 11. At this time, the lifting plate 22 is at the bottom.

[0199] Push this equipment to the vicinity of the cabinet that needs to be put on the cabinet, turn on the control unit and the power supply of the motor 2111, under the control of the control unit, the motor 2111 rotates slowly in steps, driving the rotating shaft 212 to rotate, and the rotating shaft 212 drives the active sprocket 2112 to rotate. Driven by the chain 2114, the driven sprocket 2113 on the side where the motor is not installed rotates synchronously, and the rotating shafts 212 on both sides drive the cables 213 to be pumped upward, and the cables 213 on both sides drive the lifting plate 22 to rise slowly. At the same time, the sliding wheel 222 of the lifting plate 22 will slide upward in the slide groove 16 opened in the box-type body 11 and the extension plate 123, which can effectively guide and prevent the motor 2111 from falling quickly after stopping. After the server is stably lifted to the required height, the server is pushed to move on the ball 221 and separate from the lifting plate 22, so as to achieve the purpose of putting it on the cabinet.

[0200] If the server needs to be removed from the rack, the server on the cabinet only needs to be pushed onto the ball 221 of the lifting plate 22. Under the control of the control unit, the motor 2111 rotates in the opposite direction, slowly driving the shaft 212 to rotate, and the shaft 212 without the motor is driven through the driving sprocket 2112, the driven sprocket 2113 and the chain 2114 to drive the motor-free end shaft 212 to rotate synchronously. The cable 213 is slowly released, and the sliding wheel 222 of the lifting plate 22 slides downward in the extension plate 123 and the slide groove 16 of the box body 1.

[0201] When the lifting plate 22 descends to the position of the squeezing block 31, the squeezing block 31 is squeezed, the elastic member 32 is compressed, and at the same time, the connecting rod 35 rotates around the central rod 36, driving the slider 34 to move toward the middle of the box-shaped body 11, so that the limiting block 33 is pushed out along the side wall of the movable groove 111 to the bottom of the lifting plate 22. The left and right limiting blocks 33 support the lifting plate 22 to prevent it from continuing to descend, playing a role in preventing it from falling. After the lifting plate 22 stops steadily, the server can be moved out, thereby realizing the action of the server under the cabinet.

[0202] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0203] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea.
