These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0045] In data center maintenance, the loading and unloading of computer equipment (IT equipment) is a crucial routine task. With the continuous increase in business volume, the demand for IT equipment resources in data centers continues to grow. Simultaneously, as IT equipment ages and undergoes technological innovation, the need to replace older equipment is also increasing. Consequently, the workload of loading and unloading IT equipment in data center maintenance has increased dramatically.

[0046] In existing data center rooms, the density of cabinets increases the difficulty of moving equipment and removing and loading them. Traditionally, equipment removal and loading is accomplished by placing the target equipment on a lifting rack. Operators then move the equipment from the rack to a U-position in the cabinet for installation.

[0047] This process typically requires two people to move servers and other IT equipment into the cabinet for installation and securement. Traditional methods are time-consuming, labor-intensive, and inefficient when large quantities of equipment need to be loaded and unloaded.

[0048] In addition, in data center computer rooms, simple carts or hydraulic lift carts are currently used to transport equipment. Ordinary carts can only carry equipment to the target cabinet, while conventional hydraulic lift carts can carry equipment to the front of the cabinet and lift it, but the height is only roughly determined, and manual lifting is usually still required to reach the cabinet height.

[0049] First, let’s explain the terms involved in this application:

[0050] Scissor-type hydraulic lift platforms: The platform is raised and lowered by the expansion and folding of a scissor-type support frame, powered by the expansion and contraction of a hydraulic cylinder. The scissor-type mechanical structure provides the lift with high stability, a wide working platform, and a high load capacity.

[0051] There are three main ways to install and secure equipment within a cabinet. Mounting brackets: The computer equipment is secured to the cabinet using screws using mounting brackets and other connectors on the front and rear ends. Tray / rack mounting: The tray / rack is first secured within the cabinet, and the equipment is then placed on the tray / rack for installation and securement. Slide rail mounting: Slide rails are installed within the cabinet and on both sides of the equipment, and the computer equipment is mounted within the cabinet using the rails.

[0052] Cabinet U-position: U is an internationally recognized unit of measurement for the height occupied by equipment installed within a cabinet. 1U = 44.45mm. The number of U-positions for a cabinet is typically indicated on the standard mounting posts.

[0053] The lifting frame auxiliary device provided by the present application, when it is necessary to move the equipment to be transferred to the cabinet installation position, first activates the lifting mechanism to make the lifting frame smoothly descend to a low position, providing a height for the operator to place the equipment to be transferred on the pallet. Then, by controlling the lifting mechanism, the lifting frame is raised to a preset height. The operator needs to use the drive device to adjust the position of the pallet. Specifically, the pallet position is adjusted along the first direction and the second direction, and positioned by the positioning mechanism. Then, the operator pushes the equipment from the pallet into the cabinet and installs it. The lifting frame auxiliary mechanism designed by the present application reduces the labor intensity of the operator, improves the installation efficiency, and reduces the operational risks or errors that may occur due to manual operation.

[0054] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] In the figure, x may be a first direction, and y may be a second direction.

[0056] Combine Figures 1 to 4 As shown, the lifting frame 120 auxiliary device includes a lifting mechanism 100 , a placement platform 200 and a positioning mechanism 300 .

[0057] The lifting mechanism 100 includes a support platform 110 and a lifting frame 120. The lifting frame 120 is suitable for lifting and lowering. The support platform 110 is arranged on the lifting frame 120, and the support platform 110 provides a stable platform for the placement table 200 and the positioning mechanism 300. Optionally, the lifting frame 120 can be a scissor-type hydraulic lifting frame 120.

[0058] The placement table 200 includes a tray 210, a movable member 220, and a drive device. The movable member 220 is movably disposed on the support table 110 along a first direction, allowing the tray 210 to move in one dimension on a horizontal plane. The tray 210 is used to place the device to be transferred. The tray 210 is movably disposed on the movable member 220 along a second direction, enabling the tray 210 to move freely in a two-dimensional plane. The first direction and the second direction are perpendicular to each other. The drive device is used to drive the tray 210 and the movable member 220 to move, thereby adjusting the position of the tray 210. Optionally, the drive device may include a drive motor and a drive member, which controls the operation of the drive motor and drives the tray 210 or the movable member 220 to move via the drive member.

[0059] The positioning mechanism 300 is provided on the support platform 110 and is suitable for limiting the position when the placement platform 200 moves to the target position to ensure that the tray 210 is limited when it moves to a preset position, such as when it moves to a position close to the cabinet installation position, so as to improve the placement convenience of the equipment to be transferred.

[0060] When the equipment to be transferred needs to be moved to the cabinet installation position, the lifting mechanism 100 is first started to make the lifting frame 120 descend smoothly to a low position, providing a height for the operator to place the equipment to be transferred on the pallet 210. Then, by controlling the lifting mechanism 100, the lifting frame 120 is raised to a preset height. The operator needs to use the driving device to adjust the position of the pallet 210. Specifically, the position of the pallet 210 is adjusted along the first direction and the second direction, and positioned by the positioning mechanism 300. Then, the operator pushes the equipment from the pallet 210 into the cabinet and installs it.

[0061] The auxiliary mechanism of the lifting frame 120 designed in the present application reduces the labor intensity of the operators, improves the installation efficiency, and reduces the operational risks or errors that may be caused by manual operation.

[0062] In some embodiments, combined Figure 1 and Figure 2The auxiliary device of the lifting frame 120 can also include a horizontal laser positioning device 410, which is provided on the support platform 110. The horizontal laser positioning device 410 is used to calibrate the alignment state of the support platform 110 with the preset current position.

[0063] Specifically, the horizontal laser positioning device 410 emits a horizontal laser beam to form a horizontal reference plane for guiding the movement and positioning of the support platform 110. The operator can determine whether the support platform 110 has accurately reached the target position by observing the alignment of the laser beam with a preset target position (such as the edge or marking line of the cabinet installation position).

[0064] When there is a deviation between the laser beam and the preset target position, the operator can adjust the position of the support platform 110 through the lifting frame 120 until the laser beam is aligned with the preset target position.

[0065] It can be seen that the horizontal laser positioning device 410 improves positioning accuracy, reduces errors that may be caused by manual operation, and makes it easier for operators to quickly judge and adjust the position of the support platform 110, thereby improving installation efficiency.

[0066] In some embodiments, combined Figure 1 and Figure 2 The auxiliary device of the lifting frame 120 can also include a vertical laser positioning device 420 for determining the lifting height of the support platform 110.

[0067] Specifically, the vertical laser positioning device 420 emits a vertical laser beam, providing a visual reference to help the operator determine the current height of the support platform 110. During the lifting process, the vertical laser positioning device 420 continuously emits a vertical laser beam, and the operator can determine the lifting height of the support platform 110 by observing the projection position of the laser beam on the wall or other reference object.

[0068] When the laser beam is projected onto a preset height mark, the operator can stop the lifting operation to ensure that the support platform 110 reaches the preset height.

[0069] It can be seen that the vertical laser positioning device 420 provides a visual reference, allowing the operator to accurately control the lifting height of the support platform 110, reducing the risk of equipment damage or installation errors caused by inaccurate height judgment.

[0070] In some embodiments, combined Figure 1 and Figure 2 The positioning mechanism 300 includes a limiting device 310 and a driving assembly 320 .

[0071] Among them, there are two limiting devices 310 arranged at intervals along the first direction, and the two limiting devices 310 together constitute a restricted area. The placement table 200 is arranged between the two limiting devices 310. At least one of the two limiting devices 310 is movable to cooperate with the other to jointly limit the placement table 200. In this way, the movably set limiting device 310 can adjust its position as needed to cooperate with another fixed or semi-fixed limiting device 310 to jointly limit the placement table 200.

[0072] The drive assembly 320 is disposed on the support platform 110 and is configured to drive at least one limiting device 310 to move. Optionally, the drive assembly 320 may include components such as a motor, a reducer, and a transmission mechanism, each of which works in conjunction to convert electrical energy into mechanical energy, thereby driving the limiting device 310 to move.

[0073] In this way, when the position of the placement table 200 needs to be adjusted, the drive component 320 is started to drive at least one limiting device 310 to move, and the moving limiting device 310 will form a limiting space with another limiting device 310. Normally, the limiting space matches the size of the placement table 200. It can be understood that when the placement table 200 is moved into the limiting space, the placement table 200 will be clamped by the two limiting devices 310, thereby ensuring that the position of the placement table 200 is fixed.

[0074] It can be seen that the positioning mechanism 300 improves the positioning accuracy and stability of the placement table 200, reduces the errors caused by manual operation, and enables the placement table 200 to be quickly moved to the target position, thereby improving the installation efficiency. In addition, the design of the drive component 320 realizes the positioning and clamping of the placement table 200, improves the installation accuracy and efficiency of the equipment, and reduces the operation difficulty and labor intensity.

[0075] In some embodiments, combined Figure 1 and Figure 2 The support platform 110 includes a first side surface and a second side surface along the height direction. The support platform 110 is provided with a slide groove 111 extending along the first direction. The slide groove 111 runs through the first side surface and the second side surface. The slide groove 111 provides a track for the sliding of the limit block 311.

[0076] The limiting device 310 includes a limiting block 311 and a transmission member 312. The limiting block 311 is slidably arranged on the first side along the slide groove 111. The limiting block 311 is used to limit the movement of the placement table 200 in the first direction. At least part of the structure of the transmission member 312 is arranged on the second side. The transmission member 312 passes through the slide groove 111 and is connected to the limiting block 311. The transmission member 312 plays a role in converting the rotational motion of the threaded rod 321 into the linear motion of the limiting block 311.

[0077] The driving assembly 320 includes a threaded rod 321 , which extends along a first direction and passes through the transmission member 312 . The threaded rod 321 is threadedly engaged with the transmission member 312 . The threaded rod 321 is rotatable around a first rotation axis, and the first rotation axis is parallel to the first direction.

[0078] When the position of the limit block 311 needs to be adjusted, the threaded rod 321 is rotated. Since the threaded rod 321 is threadedly engaged with the transmission member 312, the rotation of the threaded rod 321 will be converted into linear motion of the transmission member 312. The transmission member 312 then drives the limit block 311 to move in the slide groove 111 through the connection with the limit block 311, thereby realizing the adjustment of the position of the placement table 200.

[0079] Optional, combined Figure 1 and Figure 2 The end of the threaded rod 321 can be provided with an operating handle 322. Optionally, the threaded rod 321 can also be connected to a power member, such as a motor, to drive the threaded rod 321 to rotate.

[0080] In some embodiments, combined Figure 1 and Figure 2 The transmission member 312 includes a connecting rod 3121 and a matching block 3122. The matching block 3122 is sleeved on the outside of the threaded rod 321. The connecting rod 3121 is connected to the matching block 3122 and the limit block 311 respectively. The main function of the matching block 3122 is to convert the rotational motion of the threaded rod 321 into linear motion.

[0081] Specifically, when the threaded rod 321 rotates, the matching block 3122 moves along the spiral track of the threaded rod 321 and drives the connecting rod 3121 and the limiting block 311 to move together.

[0082] That is, when the position of the limit block 311 needs to be adjusted, the threaded rod 321 rotates. Since the threaded rod 321 is threadedly engaged with the matching block 3122, the rotation of the threaded rod 321 will be converted into linear motion of the matching block 3122. The matching block 3122 is then connected to the limit block 311 through the connecting rod 3121, driving the limit block 311 to move in the slide groove 111, thereby realizing the adjustment of the position of the placement table 200.

[0083] In some embodiments, combined Figure 2 The limiting devices 310 are both movable in a first direction. The threaded rod 321 is provided with a first threaded portion 321a and a second threaded portion 321b, which are threaded in opposite directions. The two limiting devices 310 are threadedly engaged with the threaded rod 321 via the first threaded portion 321a and the second threaded portion 321b, respectively. Thus, when the threaded rod 321 rotates, the first threaded portion 321a and the second threaded portion 321b generate linear motion in opposite directions.

[0084] The design enables the two limiting devices 310 to be driven at the same time but in opposite directions, facilitating the simultaneous adjustment of the positions of the two limiting devices 310 and improving the clamping efficiency of the placement table 200.

[0085] When it is necessary to adjust the positions of the two limiting devices 310, the threaded rod 321 is rotated, and since the screw threads of the first threaded portion 321a and the second threaded portion 321b are opposite in direction, the two limiting devices 310 will move at the same time but in opposite directions to clamp the placement table 200. In addition, by precisely controlling the rotation angle of the threaded rod 321 and the movement distance of the transmission member 312, the precise adjustment of the position of the placement table 200 can be achieved, ensuring the adjustment efficiency.

[0086] In some embodiments, in combination with Figure 1 The lifting frame 120 auxiliary device further comprises a moving trolley 500 and a control device 600.

[0087] The moving trolley 500 comprises a moving seat 510 and a roller 520. The moving seat 510 is the main part of the moving trolley 500, which provides stability and load-bearing capacity for supporting the lifting frame 120 and other related components. The roller 520 is rotatably arranged on the moving seat 510 and is adapted to walk on the ground. The design of the roller 520 reduces the frictional resistance between the moving trolley 500 and the ground, making the moving trolley 500 walk on the ground and improving the adaptability of the moving trolley 500 under different ground conditions to ensure the stability and flexibility of the moving trolley 500.

[0088] Optionally, the roller 520 can be made of wear-resistant and durable materials such as rubber or polyurethane to prolong the service life and reduce noise.

[0089] The lifting frame 120 is fixedly arranged on the moving seat 510, so that the lifting frame 120 and the moving trolley 500 form an integral structure. This design enables the lifting frame 120 to move with the movement of the moving trolley 500, facilitating the reaching of different work sites.

[0090] The control device 600 is one of the core components of the lifting frame 120 auxiliary device, which is used to control at least the movement state of the lifting mechanism 100 and the driving device. In this way, the control device 600 can receive instructions from the operator and adjust the working parameters of the lifting mechanism 100 and the driving device accordingly to achieve the required lifting and moving functions.

[0091] Optionally, the control device 600 can be equipped with a display screen 610 and easy-to-operate buttons or a touch screen interface, facilitating the operator to input instructions and monitor the running state of the equipment.

[0092] Optionally, the control device 600 can also be integrated with a monitoring system, an alarm system, etc. to improve the overall functionality.

[0093] In practical applications, the introduction of the mobile trolley 500 and the control device 600 makes the lifting frame 120 auxiliary device more flexible and intelligent. The operator can adjust the height and position of the lifting frame 120 through the control device 600 to adapt to different working environments. In addition, the mobile trolley 500 enables the lifting frame 120 to move to different work sites, improving work efficiency and convenience.

[0094] In some embodiments, in combination with Figure 1 , Figure 3 and Figure 4 , the placement table 200 further comprises a locking mechanism 230 arranged on the moving piece 220 and used for locking or unlocking the tray 210 to realize the positioning effect of the tray 210 and also ensure the safety of the device to be transferred.

[0095] The locking mechanism 230 comprises a locking piece 231 arranged on the moving piece 220 and a clamping groove arranged on the tray 210. Specifically, a mounting groove is arranged on the moving piece 220, and the locking piece 231 is rotationally connected in the mounting groove.

[0096] Optionally, the locking piece 231 can be one or more buckles or protruding parts, and the protruding part can be clamped into the clamping groove on the tray 210 to realize the locking function.

[0097] The locking mechanism 230 and the tray 210 are switched between a locked state and an unlocked state. In the locked state, the locking piece 231 is clamped into the clamping groove, and in the unlocked state, the locking piece 231 is separated from the clamping groove.

[0098] Specifically, in the locked state, the locking piece 231 is clamped into the clamping groove, and this locking cooperation can realize the positioning of the tray 210, fix its position when it moves to the preset position, and also ensure the stability and safety of the device to be transferred on the placement table 200. In the unlocked state, the locking piece 231 is separated from the clamping groove, so that the operator can adjust the position of the tray 210.

[0099] By introducing the locking mechanism 230, the lifting frame 120 auxiliary device can further improve the functionality and safety of the placement table 200, thereby ensuring the stability and safety of the device to be transferred.

[0100] In some embodiments, in combination with Figure 3 , the locking mechanism 230 further comprises a reset piece 232 arranged between the locking piece 231 and the moving piece 220 and adapted to apply force to keep the locking piece 231 in the locked state to prevent the locking piece 231 from being unlocked by itself without external force. Optionally, the reset piece 232 can be made of elastic materials such as springs and elastic sheets.

[0101] Specifically, the reset member 232 is fixed in the installation groove, and the reset member 232 is at least partially connected to the locking member 231 .

[0102] When the locking member 231 is inserted into the slot on the tray 210, the reset member 232 will have a restoring force in the locking direction. In this way, when the tray 210 moves to the preset position, the locking member 231 will automatically be inserted into the slot on the tray 210. The reset member 232 has a restoring force in the locking direction, so that the locking member 231 remains in the locked state. This restoring force can ensure that the locking member 231 will not be accidentally unlocked when subjected to external force or vibration, thereby maintaining the stability and safety of the locked state.

[0103] In some embodiments, combining 1 and Figure 3 The locking member 231 includes a locking portion 231a and an operating portion 231b, and the locking portion 231a and the operating portion 231b are fixedly connected, and are suitable for driving the locking portion 231a to switch from a locked state to an unlocked state through the operating portion 231b.

[0104] Optionally, the locking portion 231a and the operating portion 231b are fixedly connected (such as by welding, bolting, etc.) to form a whole. Optionally, the locking portion 231a and the operating portion 231b can also be integrally formed.

[0105] Thus, when the tray 210 needs to be positioned, the locking portion 231a automatically snaps into the slot on the tray 210. At this time, the return member 232 (e.g., a spring) is compressed or bent, generating a restoring force in the locking direction, keeping the locking portion 231a locked. When unlocking is required, the operator can operate the portion 231b and apply a force in the opposite direction of the restoring force of the return member 232 to overcome the restoring force of the return member 232, causing the locking portion 231a to disengage from the slot, thereby unlocking the tray.

[0106] By introducing the split design of the locking member 231, that is, the fixed connection between the locking portion 231a and the operating portion 231b, the operator can conveniently control the locking and unlocking states of the locking mechanism 230, thereby improving the safety and usability of the locking mechanism 230.

[0107] In some embodiments, combined Figure 1 and Figure 4 The tray 210 includes two placement sections 211, which are separable along the second direction. This allows operators to adjust the placement area of ​​the tray 210 based on actual usage requirements. Furthermore, the two placement sections 211 can be used separately to meet different storage or transportation needs.

[0108] Optionally, a connecting structure, such as a buckle, a slide rail, etc., may be provided between the two placement portions 211 to ensure that the two placement portions 211 are firmly connected and can be easily separated.

[0109] In some embodiments, combined Figure 4 A positioning piece 240 is provided on one of the two placement parts 211, and a locking arm 250 is provided on the other. A positioning groove that is compatible with the positioning piece 240 is opened on the locking arm 250. When the two placement parts 211 need to be combined together, the positioning piece 240 will be limited to the positioning groove of the locking arm 250, thereby realizing a fixed connection between the two placement parts 211.

[0110] There can be multiple positioning members 240, and the multiple positioning members 240 are sequentially arranged along the first direction, wherein the first direction is the direction in which the two placement parts 211 approach or separate. The multiple positioning members 240 are sequentially arranged along the first direction, so that when the two placement parts 211 move to different preset positions, they can be connected through the positioning members 240 and the positioning grooves.

[0111] The positioning member 240 is configured to fix the position between the two placement portions 211 when located in the positioning groove, thereby ensuring the connection stability and safety of the two placement portions 211.

[0112] By designing the coordination between the positioning member 240 and the locking arm 250, the coordination connection between the two placement parts 211 is realized, the flexibility and practicality of the two detachable placement parts 211 are improved, and the connection stability between the two placement parts 211 is ensured, thereby improving the safety of the transportation process.

[0113] In some embodiments, the movable member 220 is provided with a plurality of limiting grooves along the second direction, and the placement portion 211 is provided with a sliding member adapted to the limiting grooves. It can be understood that when the placement portion 211 moves, the sliding member can be shifted to the corresponding limiting groove.

[0114] In some embodiments, combined Figure 4 The tray 210 further includes a support portion 212, which is provided with two groups. The support portion 212 corresponds to the placement portion 211, ensuring that the tray 210 can remain stable when carrying items and prevent tilting or collapse due to uneven weight distribution.

[0115] The support portion 212 is slidably arranged in the movable member 220 so as to adjust the position of the support portion 212. The ends of the two support portions 212 are respectively connected to one end of the placement portion 211 away from the other placement portion 211, ensuring that the placement portion 211 can be fully supported when moving or carrying items, thereby improving the overall stability of the tray 210.

[0116] By designing the support portion 212 and its sliding mechanism, the flexibility and stability of the placement portion 211 are ensured, and the safety and durability thereof when carrying articles are also ensured.

[0117] In some embodiments, a connecting groove may be provided between adjacent limiting grooves, and when the placement portion 211 moves along the first direction, it may move along the connecting groove into the adjacent limiting groove.

[0118] In some embodiments, combined Figure 1 and Figure 2 The connection between the two placement portions 211 is serrated.

[0119] The serrated connection design increases the contact area and engagement strength, making the two placement portions 211 more secure when connected. This design, similar to the meshing of gears, effectively prevents the placement portions 211 from moving or separating when subjected to external forces, thereby improving the structural strength and versatility of the tray 210.

[0120] Finally, it should be noted that other embodiments of the present invention will readily occur to those skilled in the art after considering the specification and practicing the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. It is not limited to the precise structure described above and shown in the drawings, and various modifications and variations may be made without departing from the scope of this application.
