Technical Field

[0001] The utility model relates to the technical field of server hoisting, in particular to a hoisting device. Background Art

[0002] When installing or repairing a server in a liquid-cooled cabinet, due to the server's heavy weight, it is labor-intensive for operators to directly move the server, and generally lifting equipment is required for auxiliary lifting.

[0003] Most of the existing technologies directly hoist the server through a hoisting device, but this hoisting method is relatively cumbersome to operate, and multiple hooks need to be set during hoisting, and the stability is poor.

[0004] Therefore, it is necessary to provide a lifting device that is easy to use and has high stability. Utility Model Content

[0005] The present invention aims to solve one of the technical problems in the related art to a certain extent. To this end, the present invention provides a lifting device with high lifting stability and can adapt to the lifting requirements of servers of different sizes.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A lifting device for lifting a server includes a supporting portion and a lifting portion. The lifting portion is arranged in the middle of the supporting portion. The lifting portion includes a lifting hole for connecting a lifting device. Both ends of the supporting portion are respectively provided with hook portions distributed at intervals. The hook portions are used to hook and connect the server. The spacing between the hook portions at the same end is adjustable.

[0008] In this technical solution, when the server is lifted, the server is hooked through the hook part of the lifting device. There is a certain distance between the hook parts at both ends, and they can be hooked on the two ends of the server respectively, providing the server with at least two connection points with a certain width, thereby improving the stability of the server during the lifting process. In addition, the spacing between the hook parts at the same end is adjustable, which can adapt to the lifting requirements of servers of different widths.

[0009] Furthermore, the support portion includes two support plates arranged side by side with a spacing therebetween, the hook portions are provided at both ends of each support plate, and the spacing between the two support plates is adjustable, thereby increasing the overall width of the support portion and improving the stability of the hoisting.

[0010] Furthermore, the support portion includes a plurality of connecting screws connecting the two support plates, each support plate is provided with a first connecting hole corresponding to the plurality of connecting screws, the ends of the connecting screws respectively pass through the first connecting holes of the two support plates, and each support plate is provided with a first locking nut on both sides that is threadedly connected to the connecting screws, and the first locking nut can fix the support plate to the connecting screws. The design of the connecting screws and the first locking nut facilitates assembly and facilitates adjustment of the spacing between the two support plates.

[0011] Furthermore, the hanging part includes a hanging plate, which is arranged between two support plates. The hanging plate is provided with second connecting holes corresponding to at least two connecting screws respectively, and the connecting screws pass through the second connecting holes. Second locking nuts threadedly connected to the connecting screws are respectively provided on both sides of the hanging plate, and the second locking nuts can fix the hanging plate on the connecting screws.

[0012] Furthermore, the bottom surface of the support plate is configured as a plane, and the top surface of the support plate includes a plane segment located at each end of the support plate and an inclined segment located between the two plane segments. One end of each inclined segment is connected to the plane end of its corresponding end, and the other end of each inclined segment is connected at the middle of the support plate. The middle of the support plate protrudes from the two ends of the support plate. This improves the structural strength of the support plate and increases the load-bearing capacity of the lifting device.

[0013] Furthermore, the hook portion is arranged on the plane section, thereby improving the stability and convenience of the connection between the hook portion and the server.

[0014] Furthermore, the hooking portion includes a hook groove arranged on the top of the supporting portion.

[0015] Furthermore, the hooking parts at both ends are symmetrically distributed about the center of the supporting part, so that the lifting device is subjected to balanced forces during hoisting, thereby improving stability.

[0016] Furthermore, the distance between the two hooking parts at the same end is not less than 5 cm.

[0017] Furthermore, the distance between the hoisting hole and the bottom surface of the support portion is greater than the distance between the hook portion and the bottom surface of the support portion, so that the entire lifting device is stressed into a triangular structure, thereby improving stability.

[0028] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described in the embodiments are intended to explain the present invention and are not to be construed as limiting the present invention.

[0029] References in this specification to "one embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment disclosed herein. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0030] The lifting device in the prior art generally uses a hook lifting handle, which has poor stability; the angle needs to be adjusted to maintain lifting stability, which is time-consuming and labor-intensive; in addition, four hooks are required during lifting, which is a large number and inconvenient to connect to the server.

[0031] See attached Figure 1 、 4 One embodiment of the present invention discloses a lifting device 20 for lifting a server 10, comprising a supporting portion and a lifting portion, wherein the lifting portion is arranged in the middle of the supporting portion, and the lifting portion includes a lifting hole 221 for connecting a lifting device, and hook portions distributed at intervals are respectively provided at both ends of the supporting portion, and the hook portions are used to hook and connect the server 10, and the spacing between the hook portions at the same end is adjustable.

[0032] See attached Figure 4 、 5 The server 10 in the present invention is placed in a liquid-cooled cabinet and immersed in liquid cooling during operation. When the server 10 enters or takes out the liquid-cooled cabinet, the lifting device 20 in this embodiment is required. During installation, the hook portion of the lifting device 20 is hooked on the handles at both ends of the server 10, and the lifting hole 221 of the lifting portion is connected to the hook or lifting rope of the lifting equipment. During the lifting process, the lifting device 20 can support both ends of the server 10, so that the overall force of the server 10 is relatively balanced. In addition, there is a distance between the hook portions at the same end, which is equivalent to providing at least four points of support for the server 10, thereby improving the stability of the lifting.

[0033] In addition, the spacing between the hook parts at the same end in this embodiment is adjustable, so that in actual use, the spacing between the hook parts can be adjusted according to the size of the server 10, which can adapt to the lifting requirements of servers 10 of different widths, further improve the versatility of the lifting device 20, and improve the stability of lifting large-sized servers 10.

[0034] The structure of the support portion is not specifically limited in this embodiment. The support portion can be designed as a single component or as a structure assembled from multiple components, as long as the support portion has sufficient strength. Furthermore, the specific structure of the hook portion is not specifically limited in this embodiment. In actual configuration, the hook portion can be configured as a hook slot 26, a hook, a hole, a clamping member, etc., as long as the hook portion can maintain a stable and reliable connection with the server 10 when the server 10 is hoisted.

[0035] In addition, the adjustment of the distance between the hooking parts can be set to be only the adjustment of the distance between the hooking parts. Of course, the adjustment of the distance between the hooking parts can also be driven by the adjustment of other components on the support part.

[0036] See attached Figure 1 、 2 3. As one embodiment of the present invention, the support portion includes two support plates 21 arranged side by side with a spacing therebetween. The hook portion is provided at both ends of each support plate 21, and the spacing between the two support plates 21 is adjustable. In this embodiment, the support portion is configured as a structure of two support plates 21. The support plates 21 themselves have high strength and can improve the load capacity of the lifting device 20. During design, the support plates 21 can be made of steel plates, wooden plates, or other materials. Generally, stainless steel plates are used. The thickness of the stainless steel plates can be set to 304 stainless steel of not less than 5 mm. The end faces of the two support plates 21 are arranged relative to each other. In this way, the overall weight of the lifting device 20 can be reduced while ensuring the lifting strength.

[0037] The hooking parts in this embodiment are arranged at both ends of the support plate 21, so when adjusting the spacing of the hooking parts, it is only necessary to adjust the distance between the two support plates 21, which is convenient to adjust. Moreover, when adjusting the spacing of the hooking parts, the spacing between the support plates 21 is also adjusted accordingly, which can better adapt to the lifting requirements of servers 10 of different sizes and improve the stability of the lifting. The hooking part is set to a structure integrated with the support plate 21, which can also improve the overall strength of the hooking part.

[0038] See attached Figure 1 The support portion of one embodiment of the present invention includes a plurality of connecting screws 23 connecting the two support plates 21, and each support plate 21 is provided with a first connecting hole 211 corresponding to the plurality of connecting screws 23. The two ends of the connecting screw 23 respectively pass through the first connecting holes 211 on the two support plates 21, and each of the two sides of the support plate 21 is provided with a first locking nut 24 threadedly connected to the connecting screw 23. The first locking nut 24 can fix the support plate 21 on the connecting screw 23.

[0039] In this embodiment, the two support plates 21 are connected by a plurality of spaced-apart connecting screws 23, and the plurality of connecting screws 23 are distributed along the length direction of the support plate 21, so that a plurality of support points can be provided for the length direction of the support plate 21, thereby improving the overall strength. The assembly structure of the connecting screws 23 and the first locking nuts 24 and the support plates 21 in this embodiment is easy to assemble, and in actual use, when adjusting the spacing, it is only necessary to adjust the position of the support plates 21 on the connecting screws 23. When the support plates 21 are adjusted into place, the first locking nuts 24 on both sides of the support plates 21 are tightened, and the support plates 21 can be clamped and fixed in the corresponding position through the threaded connection between the first locking nuts 24 and the connecting screws 23, and the spacing adjustment is convenient.

[0040] It should be noted that the first connecting hole 211 in this embodiment can be set as a smooth hole or as a threaded hole structure that cooperates with the connecting screw 23. This embodiment does not make specific limitations on this. In addition, the spacing between adjacent first connecting holes 211 on each support plate 21 can be reasonably designed according to the total length of the support plate 21, and the distance between two adjacent first connecting holes 211 on the same support plate 21 (that is, the distance between two adjacent connecting screws 23) can be determined based on force analysis.

[0041] When installing the lifting device 20 in this embodiment, first screw the first locking nut 24 located on the inner side of the support plate 21 into the middle position of the connecting screw 23, then pass one end of the connecting screw 23 through the first connecting hole 211 on the support plate 21, and then screw another first locking nut 24 on the other side of the support plate 21 on the connecting screw 23, and then tighten the first locking nuts 24 on both sides of the support plate 21 in opposite directions to fix the position of the support plate 21.

[0042] See attached Figure 1 The hoisting portion of one embodiment of the present invention includes a hoisting plate 22, which is arranged between two support plates 21. The hoisting plate 22 is provided with second connection holes corresponding to at least two connection screws 23, and the connection screws 23 pass through the second connection holes. Second locking nuts 25 are respectively provided on both sides of the hoisting plate 22, which are threadedly connected to the connection screws 23. The second locking nuts 25 can fix the hoisting plate 22 on the connection screws 23. It should be noted that the hoisting plate 22 in the present invention is arranged in the middle part in both the width direction and the length direction of the support part, so as to ensure the balance of force during hoisting and improve stability. The connection process between the hoisting plate 22 and the connection screws 23 is the same as the connection process between the support plate 21 and the connection screws 23 mentioned above.

[0043] In one embodiment of the present invention, the bottom surface of the support plate 21 is configured as a plane. This configuration facilitates adaptation to the structure of the server 10 itself and avoids interference with accessories on the server 10. The top surface of the support plate 21 includes a plane section 212 located at both ends of the support plate 21 and an inclined section 213 located between the two plane sections 212. One end of the two inclined sections 213 is connected to the plane end of their corresponding ends, and the other ends of the two inclined sections 213 are connected in the middle of the support plate 21. The middle of the support plate 21 protrudes from the two ends of the support plate 21. It can be seen that the overall structure of the support plate 21 is a structure in which the middle is higher than the two ends. This structural design can improve the structural strength of the support plate 21 and increase the load-bearing capacity of the lifting device 20. It is also beneficial for the force received by the support plate 21 during lifting to form a triangular structure, thereby improving stability.

[0044] In order to ensure the stability of the lifting, the hook portion of one embodiment of the present invention is arranged on the plane section 212. The hook portion is arranged on the plane section 212, which facilitates the production and processing of the hook portion, and is convenient for leveling with the server 10, and can also improve the reliability of the connection.

[0045] The hook portion of one embodiment of the present invention includes a hook groove 26 provided on the top of the support portion. Figure 4 、 5 When in use, the handle 11 on the server 10 is stuck in the hook groove 26. When lifting, the server 10 will be restricted in the hook groove 26 under the action of its own gravity. The hook grooves 26 at both ends of the support part can well limit the server 10 to prevent the server 10 from shaking during the lifting process. It should be noted that the depth of the hook groove 26 is generally greater than the height of the handle 11, so that the handle 11 can be completely placed in the hook groove 26, thereby improving stability and reliability. In actual design, the utility model does not make specific restrictions on the shape of the hook groove 26. The cross-section of the hook groove 26 can be set to a variety of shapes such as U-shape, arc shape, V-shape, dovetail shape, etc. In addition, in some cases, a locking device can be provided at the open end of the hook groove 26 to prevent the handle 11 from detaching from the hook groove 26, thereby improving the safety of lifting.

[0046] To further improve the balance of forces on the lifting device 20 and enhance stability during lifting, the hooks at both ends of the present invention are symmetrically distributed about the center of the support portion. This ensures that the torques at both ends of the lifting device 20 are equal during lifting, preventing the server 10 from tilting and improving the stability and balance of the lifting.

[0047] In one embodiment of the present invention, the distance between the two hooking parts at the same end is not less than 5 cm. When the size of the server 10 is larger, the distance between the two hooking parts should generally be not less than 1 / 2 of the width of the corresponding server 10.

[0048] See attached Figure 2 In one embodiment of the present invention, the distance between the hoisting hole 221 and the bottom surface of the support portion is greater than the distance between the hook portion and the bottom surface of the support portion. This allows the hoisting device 20 to form a triangular structure as a whole, which makes the force more stable and improves stability.

[0049] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are included within the scope of the claims.
