DETAILED DESCRIPTION

[0019] Example One As Figure 1 And Figure 2As shown, a server cabinet with lifting device is provided, which comprises a cabinet body 1, a vertically movable bracket 7 arranged in the cabinet body 1, and a lifting mechanism 2 for driving the vertical displacement of the bracket 7. The lifting mechanism 2 comprises four first guide rails 23, two on the left and two on the right. The two first guide rails 23 on the same side are vertically fixedly connected to the side wall of the cabinet body 1. The first guide rails 23 are made of high-strength aluminum alloy. At least one first sliding block 24 is slidingly connected to each first guide rail 23. The first sliding block 24 is guided in cooperation with the first guide rail 23. The two first guide rails 23 (a total of four) on the left and right sides of the cabinet body 1 provide rigid guidance to ensure the vertical movement precision. The side surfaces of the adjacent two first sliding blocks 24 are fixedly connected to the first support plates 25, forming a stable frame structure to avoid the inclination of the bracket 7. The bracket 7 is installed between the two first support plates 25 on the left and right. The bracket 7 is used for supporting the server host. Four hoisting ropes 22 arranged in a matrix are arranged inside the cabinet body 1. The hoisting ropes 22 can be made of carbon fiber material. The four hoisting ropes 22 are two on the left and two on the right. The two hoisting ropes 22 on the same side are located at the front and rear ends of the side surface of the first support plate 25 and are used for suspending the bracket 7 to ensure stable lifting. The four hoisting ropes 22 (arranged in a matrix) are connected to the first support plate 25, forming a double protection to share the load and prevent single-point failure risk. A winding mechanism 21 for winding the four hoisting ropes 22 is installed at the top of the cabinet body 1. The winding mechanism 21 is embedded in the cabinet top and does not occupy the internal space of the cabinet, maintaining the standard cabinet appearance compatibility. The bottom end of the hoisting rope 22 is fixedly connected to the first support plate 25. After the winding mechanism 21 winds the hoisting rope 22, the first sliding block 24 is driven to vertically displace along the first guide rail 23 to adjust the distance between the bracket 7 and the ground. On the one hand, when the server is installed in the cabinet from top to bottom, manual lifting is reduced, and the installation of the server is more stable and safe. In addition, when the hoisting rope 22 and the first support plate 25 on the side surface of each bracket 7 are connected, multiple brackets 7 can also be simultaneously driven to vertically displace, which is convenient for adjusting the height of the bracket 7 for equipment maintenance. The winding mechanism 21 can simultaneously wind the four hoisting ropes 22. The winding mechanism 21 comprises a first box body 211 fixedly connected to the top of the cabinet body 1. First through holes 2110 are formed at the four corners of the bottom of the first box body 211. The four first through holes 2110 correspond to the four hoisting ropes 22. A guide wheel 212 is installed at each of the four first through holes 2110. The guide wheel 212 is used for guiding and reducing the friction and wear between the hoisting rope 22 and the through hole, prolonging the service life. Two rotatable winding drums 214 are symmetrically installed inside the first box body 211. The two ends of the winding drum 214 are connected to the inside of the first box body 211 through a bearing seat 33. The hoisting rope 22 is connected to the winding drum 214 after passing through the first through hole 2110 and the guide wheel 212. A connecting shaft 215 is connected between the two winding drums 214. The two ends of the connecting shaft 215 are connected to the inside of the first box body 211 through a bearing member. A bidirectional drive motor 213 is installed in the first box body 211 for simultaneously driving the rotation of the two winding drums 214.A bidirectional drive motor 213 achieves rigid linkage between the left and right winding drums 214 via a connecting shaft 215, ensuring complete synchronization of the winding and unwinding of the slings 22 on both sides. In use, the bidirectional drive motor 213, supported by the first housing 211, synchronously drives the left and right winding drums 214 to rotate via a timing belt 36, thereby winding the two slings 22 on the same side. This causes the first slider 24, connected to the first support plate 25, to slide vertically on the first guide rail 23, thus vertically moving the bracket 7 between the two first support plates 25. The distance between the bracket 7 and the ground is adjustable.

[0020] Example 2 like Figure 3 As shown, ball screws 31 are vertically installed on the left and right sides inside the cabinet 1. The ball screws 31 are fixedly connected to the inner wall of the cabinet 1 along the Z-axis. The two ends of the ball screws 31 can be supported on the inner wall of the cabinet 1 by bearing seats 33, ensuring that the ball screws 31 can only rotate and cannot move axially. Each ball screw 31 is threaded with a ball nut 32, which is fixedly connected to the first support plate 25 by bolts. When the ball screw 31 rotates, the ball nut 32 moves up and down along the Z-axis, driving the bracket 7 to rise and fall. The unit is equipped with a height adjustment auxiliary mechanism 3 for synchronously driving the rotation of two ball screws 31. The height adjustment auxiliary mechanism 3 includes a second housing 310, which is fixed to the bottom of the cabinet 1. A synchronous pulley 35 is installed at one end of each of the left and right ball screws 31 that passes through the second housing 310. A synchronous belt 36 connects the two synchronous pulleys 35. The bottom ends of the two ball screws 31 are linked through the synchronous pulleys 35 and the synchronous belt 36 to ensure that the left and right ball screws 31 rotate completely synchronously, preventing the bracket 7 from tilting. A first worm gear 37 is installed at the end of the screw 31. A first worm 38, which meshes with the first worm gear 37, is horizontally arranged inside the second housing 310. A first motor 34 for driving the first worm 38 to rotate is installed inside the second housing 310. The extended end of the first worm 38 protrudes from the side of the second housing 310 and is equipped with a first handwheel 39. The first worm gear 37 is installed at the end of one of the screws and meshes with the horizontal first worm 38 to form a self-locking reduction mechanism (to prevent the load from slipping). The worm is driven by the first motor 34, and the end of the worm extends... Extend the first handwheel 39 to support electric and manual dual-mode operation (manual adjustment is possible when power is off). During operation, start the first motor 34 to drive the first worm gear 38 to rotate, which in turn drives the first worm wheel 37 and the connected ball screw 31 to rotate. The ball screws 31 on both sides rotate synchronously through the synchronous belt 36, and the ball nut 32 moves along the axial direction of the ball screw 31, pushing the bracket 7 to rise and fall smoothly. When power is off, rotate the first handwheel 39 to manually drive the first worm gear 38 and the first worm wheel 37 to realize the rotation of the ball screw 31 and the adjustment of the position of the bracket 7.

[0021] Example 3 likeFigure 4 and Figure 5 As shown in the figure, the first support plate 25 is provided with a first flat pushing mechanism 4 for driving the bracket 7 to move back and forth along the Y-axis direction, which is used to drive the bracket 7 to move horizontally along the Y-axis (front and back direction) to enable the server to be smoothly pushed out or retracted, facilitating maintenance or installation; the first flat pushing mechanism 4 comprises a first bottom plate 41 fixedly connected to the side of the first support plate 25, a V-shaped guide rail 43 installed on the side of the first bottom plate 41, a roller mounting plate 46 located on the side of the V-shaped guide rail 43, and a V-shaped roller 44 rotatably installed on each of the four corners of the side of the roller mounting plate 46, which is in rolling cooperation with the V-shaped guide rail 43; the V-shaped guide rail 43 is fixed on the side of the first bottom plate 41 to provide a high-rigidity guide rail, and the V-shaped roller 44 is installed on the four corners of the roller mounting plate 46 to ensure smooth movement and strong anti-unbalanced load capacity; a first housing 42 covers the side of the first bottom plate 41, which effectively blocks dust from entering the precision guide rail area, and is fixedly connected with the first bottom plate 41 and horizontally provided with a first guide through slot 421 on the side thereof; symmetrically distributed first I-shaped brackets 47 ensure uniform transmission of pushing force and prevent the bracket 7 from tilting, and one end of each of the first I-shaped brackets 47 is fixedly connected to the side of the roller mounting plate 46 and the other end thereof is connected to the side of the bracket 7 through the first guide through slot 421, which limits the movement path of the I-shaped bracket to ensure linear movement of the Y-axis; a flat pushing cylinder 45 is installed on the side of the first bottom plate 41 and serves as a driving source to directly push the roller mounting plate 46 to move along the Y-axis; in the pushing-out process, the piston rod of the flat pushing cylinder 45 is extended to push the roller mounting plate 46 to slide forward along the V-shaped guide rail 43, and the bracket 7 is driven by the roller mounting plate 46 through the first I-shaped bracket 47 to move forward synchronously, thereby realizing outward pushing of the server; in the retraction process, the piston rod of the cylinder is retracted, the roller mounting plate 46 moves backward, and the bracket 7 is reset to the cabinet through the I-shaped bracket.

[0022] As Figure 6 and Figure 7As shown, the first I-shaped support 47 and the bracket 7 are provided with a second flat pushing mechanism 5, which takes the first I-shaped support 47 as a support basis and can push the bracket 7 to displace along the Y-axis direction, and the second flat pushing mechanism 5 (Y-axis direction fine displacement) is installed between the first I-shaped support 47 and the bracket 7 and serves as an extension of the first flat pushing mechanism 4, which is used to realize the secondary fine translation (Y-axis direction) of the bracket 7 and is suitable for scenes requiring multi-stage adjustment or precise positioning (such as server plugging, maintenance alignment); the second flat pushing mechanism 5 includes a second housing 51, the top of the second housing 51 is detachably connected with a second cover plate 52, the closed structure protects the internal transmission components, is dustproof and safe, the side of the second housing 51 is provided with a second guide through slot 511, the second guide through slot 511 limits the movement path of the L-shaped support, ensures strict movement along the Y-axis direction, the second housing 51 is fixedly connected to the side of the first I-shaped support 47, the inside of the second housing 51 is provided in parallel with a screw rod 59 and a first guide optical axis 53, the second housing 51 is installed with a second motor 58 that drives the rotation of the screw rod 59, one end of the screw rod 59 that penetrates out of the second housing 51 is installed with a second hand wheel 55, the screw rod 59 is sleeved with an internally threaded sleeve 57, the screw rod 59 is in threaded cooperation with the internally threaded sleeve 57, and the rotational movement of the screw rod 59 is converted into linear movement, the first guide optical axis 53 is sleeved with a first sleeve 54 that can slide, the first sleeve 54 moves synchronously with the internally threaded sleeve 57, the inside of the second housing 51 is provided with a second L-shaped support 56, the bottom of the second L-shaped support 56 is fixedly connected with the internally threaded sleeve 57 and the first sleeve 54, forming a rigid linkage, the side penetrates through the second guide through slot 511 and is connected with the bracket 7, pushing the bracket 7 to move back and forth, electric mode: starting the second motor 58 to drive the screw rod 59 to rotate → the internally threaded sleeve 57 drives the second L-shaped support 56 to translate along the optical axis → the bracket 7 is finely adjusted in position, the first sleeve 54 slides on the first guide optical axis 53, eliminating the lateral force of the screw rod 59 transmission, ensuring stability; manual mode (power failure or fine adjustment), rotating the second hand wheel 55, manually rotating the screw rod 59, realizing the position adjustment of the bracket 7.

[0023] Example Four As Figure 8 and Figure 9As shown, the bracket 7 is provided with a centering and clamping mechanism 6 below the bracket 7, which is located below the bracket 7 and is used for bidirectional synchronous clamping of the server equipment, ensuring that it is fixed in the center of the bracket 7 and preventing deviation during transportation or lifting. The design is divided into two schemes of pneumatic drive and worm drive. The centering and clamping mechanism 6 comprises a third shell 61 fixedly connected to the bottom of the bracket 7. Four second guide rails 62 are symmetrically distributed inside the third shell 61, providing a high-rigidity sliding track. Each second guide rail 62 is fixedly connected to the bottom of the third shell 61. A second sliding block 63 is slidably connected to each second guide rail 62. A U-shaped clamping piece 64 is fixedly connected to the two second sliding blocks 63 on the same side. A third guide groove 71 is formed in the bracket 7 for the centering displacement of the U-shaped clamping piece 64. Four guide rails are symmetrically fixed to the bottom of the third shell 61, providing a high-rigidity sliding track. A sliding block is slidably connected to each guide rail. The U-shaped clamping piece 64 is fixed to the two sliding blocks on the same side. The U-shaped clamping piece 64 extends out of the side of the bracket 7 through the third guide groove 71. A connecting plate 65 is connected between the two second sliding blocks 63 on the same side. The design of four guide rails + connecting plate 65 ensures that the displacements of the clamping pieces on both sides are consistent, avoids unbalanced load, realizes synchronous movement, and a driving mechanism for driving the centering displacement of the connecting plate 65 is installed in the third shell 61.

[0024] The first driving mode: the driving mechanism is a bidirectional telescopic cylinder 661. The bidirectional telescopic cylinder 661 is installed at the center of the third shell 61. The telescopic rods at both ends of the bidirectional telescopic cylinder 661 are hingedly connected to the corresponding connecting plates 65. The bidirectional telescopic cylinder 661 is centrally installed, and the telescopic rods at both ends are hingedly connected to the connecting plates 65, directly pushing the U-shaped clamping piece 64 to be centered and synchronized or separated.

[0025] The second driving mode: the driving mechanism comprises a concentric shaft 664 rotatably connected at the center of the third shell 61. A rotating wheel 662 and a second worm wheel 665 are fixedly connected to the concentric shaft 664. A first connecting rod 663 is rotatably connected between the rotating wheel 662 and the two connecting plates 65. A second worm 666 meshing with the second worm wheel 665 is arranged in the third shell 61. A third motor 667 for driving the second worm 666 to rotate is arranged in the third shell 61. A third hand wheel 668 is installed at one end of the second worm 666 protruding out of the third shell 61. The third motor 667 drives the second worm 666 → the second worm wheel 665 drives the concentric shaft 664 to rotate → the rotating wheel 662 pulls the connecting plate 65 to move by the first connecting rod 663, or manually rotates the third hand wheel 668 to manually drive the second worm 666, realizing clamping adjustment. The second worm 666 and the second worm 666 scheme have strong self-locking property, which is suitable for long-term fixed and anti-loose environment.

[0026] Embodiment five As Figure 10 and Figure 11As shown, a limiting mechanism 8 is arranged between two adjacent first sliders 24, which can quickly lock the first slider 24 on the first guide rail 23 to limit the imbalance of the bracket 7 from falling, thereby playing a safety limiting role. The limiting mechanism 8 includes a third sleeve 81, two cavities (first cavity 811 and second cavity 812) are arranged in the third sleeve 81, and a left and right sliding piston rod (first piston rod 82 and second piston rod 83) is arranged in each cavity. The left and right piston rods enter and exit the two cavities to change the overall length (elongate or shorten) of the limiting mechanism 8. A sealing ring 85 is arranged between the end of each piston rod and the inner wall of the cavity to reduce the gap, such as the sealing ring 85 fixedly installed at the end of the first piston rod 82 and the second piston rod 83. The pressure in the cavity between the first piston rod 82 and the second piston rod 83 is changed (increased or decreased) to adjust the relative displacement of the first piston rod 82 and the second piston rod 83 in the cavity. An electromagnetic valve 86 is installed on the third sleeve 81, which opens and closes the pressurization channel or negative pressure channel to drive the first piston rod 82 and the second piston rod 83 to move away from each other or move towards each other. A spring 84 is arranged in the cavity between the first piston rod 82 and the second piston rod 83, and the two ends of the spring 84 abut against the side walls of the two piston rods. Two first sliders 24 are designed correspondingly. The first slider 24 includes a slider body 242, and a first accommodating cavity 243 is arranged on the slider body 242. The first guide rail 23 can be inserted into the first accommodating cavity 243. The side of the slider body 242 is hingedly connected with a turnover plate 241. The limiting mechanism 8 is supported by the first support plate 25. When the body of the limiting mechanism 8 is elongated or shortened, the turnover plate 241 is turned over, thereby changing the frictional resistance between the turnover plate 241 and the side wall of the first guide rail 23. When the external monitoring facility detects abnormal falling speed data, the monitoring facility (control equipment or PLC controller) controls the electromagnetic valve 86 to open the pressurization channel, so as to drive the first piston rod 82 and the second piston rod 83 to extend outward and tightly abut against the side of the guide rail, thereby playing a role of stopping or reducing the falling speed.
