Description

Technical Field

[0001] This application relates to the field of equipment hoisting technology, and in particular to a support device. Background Technology

[0002] Chemical equipment includes vertical equipment, such as distillation towers, washing towers, and absorption towers. These vertical equipment are supported by skirts at the bottom, with lifting lugs on the skirts and at the top. When the vertical equipment needs to be installed in a designated location, a crane is used to lift the equipment in a horizontal position using the two lifting lugs. Then, by rotating the equipment, it is turned from a horizontal position to a vertical position before being installed in the designated location.

[0003] In related technologies, during the process of a crane hoisting a vertical device, the skirt support is deformed by the lifting force of the crane, making it impossible to quickly install the vertical device to the designated position.

[0004] Therefore, in related technologies, there is a technical problem that the skirt support of vertical equipment is prone to deformation under stress. Utility Model Content

[0005] This application provides a support device aimed at solving the technical problem of easy deformation of the skirt support of vertical equipment under stress, thereby reducing the deformation of vertical equipment using the support device during hoisting and improving the installation reliability of vertical equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application embodiment provides a support device, the support device comprising:

[0008] The skirt base is ring-shaped and has an internal accommodating space. The outer wall of the skirt base has a hanging lug, and the inner wall of the skirt base has three mounting positions. The three mounting positions are arranged at intervals along the circumference of the skirt base, and one of the three mounting positions is on the same straight line as the hanging lug.

[0009] The support unit includes three support frames disposed within the accommodating space and along the circumference of the skirt base. The three support frames and three mounting positions are alternately arranged in sequence, and both ends of each support frame are detachably connected to the corresponding mounting position. Each support frame includes a connecting mechanism and two fixing members. The two fixing members are arranged opposite to each other along the extension direction of the support frame. The connecting mechanism is disposed between the two fixing members and is detachably connected to each of the two fixing members. The connection position of the connecting mechanism to at least one of the two fixing members is adjustable so that the length of the support frame is adjustable.

[0010] In some embodiments, the connecting mechanism includes a threaded connector having a first external thread at both ends, and two fixing members having threaded holes that match the first external threads. The threaded connector is threadedly engaged with the fixing members to make the spacing between the two fixing members adjustable.

[0011] In some embodiments, the threaded connector has a limiting structure on its peripheral wall, and along the axial direction of the threaded connector, the projection of the limiting structure covers the projection of the threaded hole; and / or,

[0012] The connecting mechanism further includes a plurality of first fasteners, which are arranged at intervals along the circumference of the threaded connector, and both ends of each first fastener are detachably connected to the corresponding fixing member.

[0013] In some embodiments, the fastener includes at least two first fixing plates, a connecting pipe, and a second fixing plate. The at least two first fixing plates are spaced apart along the extension direction of the support frame, and the connecting pipe is connected between two adjacent first fixing plates. The second fixing plate is perpendicular to and fixedly connected to the first fixing plate on the side away from the connecting mechanism, and the second fixing plate is detachably connected to the mounting position.

[0014] The threaded hole is located on the first fixing plate near the side of the connecting mechanism.

[0015] In some embodiments, the support frame further includes a plurality of second fasteners, each of the second fixing plates having two first elongated holes, the second fasteners passing through the first elongated holes and being detachably connected to the corresponding mounting position.

[0016] In some embodiments, the mounting position has a mounting plate, the profile of the mounting plate facing the inner wall of the skirt seat matches the profile of the inner wall of the skirt seat, and each of the second fixing plates is detachably connected to the corresponding mounting plate by the second fastener.

[0017] In some embodiments, the mounting position further includes a reinforcing plate whose outline matches the outline of the inner wall surface of the skirt, and the reinforcing plate is connected between the mounting plate and the mounting position.

[0018] In some embodiments, the support device further includes three sets of fastening units, each of the reinforcing plates being detachably connected to the mounting position via one set of the fastening units.

[0019] In some embodiments, the fastening unit includes two sets of third fasteners, with the lug located between the two sets of third fasteners.

[0020] In some embodiments, the three mounting positions form an equilateral triangle.

[0021] The support device provided in this application includes a skirt and a support unit. On the one hand, by setting the support unit in the accommodating space inside the skirt, the support unit and the skirt together bear the force transmitted from the lifting lug during the hoisting process, thereby reducing the force on the skirt, reducing the amount of deformation, and improving the installation reliability of the vertical equipment using the support device.

[0022] Secondly, by setting three support frames in the support unit, and all three support frames can be detachably connected to the skirt, the support unit can be completely removed from the skirt after hoisting, so as to be reused, thereby reducing material waste and lowering hoisting costs.

[0023] Thirdly, by setting two fixing parts and a connecting mechanism in each support frame, each support frame has multiple connection positions. These multiple connection positions can work together to bear the force, thereby distributing the torque on the support frame to multiple connection positions and improving the support reliability of each support frame. Furthermore, the connection position between the connecting mechanism and at least one of the two fixing parts is adjustable, so that the length of the support frame is adjustable. This allows the same support frame to be used for vertical equipment of different sizes, thereby improving the applicability and versatility of the support frame.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Chemical equipment includes vertical structures such as distillation columns, washing columns, and absorption columns. These vertical structures are supported by skirt supports at the bottom, with lifting lugs on both the skirt supports and the top of the structure. When the vertical equipment needs to be installed in a designated location, a crane is used to lift it from a horizontal position using the two lifting lugs. Then, by rotating, the equipment is turned from a horizontal to an vertical position before installation. During the crane's lifting process, the skirt supports are subjected to the lifting force, causing deformation and hindering the rapid installation of the vertical equipment. Therefore, there is a technical problem regarding the susceptibility of the skirt supports of vertical equipment to deformation under stress.

[0050] To address the aforementioned technical problems, this application provides a support device. Exemplarily, the support device is applicable to vertical equipment, including but not limited to distillation columns, washing columns, and absorption columns. In some embodiments, the weight of the vertical equipment is less than or equal to 360t, and the diameter of the vertical equipment ranges from 2m to 6m.

[0051] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0052] See attached image. Figure 1 This is a schematic diagram of a support device provided in an embodiment of this application. Figure 1 As shown, the support device 10 includes a skirt base 100 and a support unit 200.

[0053] The skirt base 100 is annular and has an internal accommodating space 110. The outer wall of the skirt base 100 has a lifting lug 120. When a crane lifts a vertical device with the skirt base 100, the lifting lug 120 is a direct component for lifting and connecting with the crane's lifting components. In addition, the inner wall of the skirt base 100 has three mounting positions 130. The three mounting positions 130 are arranged at intervals along the circumference of the skirt base 100, and one of the three mounting positions 130 is located on the same straight line as the lifting lug 120, that is, one of the three mounting positions 130 and the lifting lug 120 are at the same corresponding position on the inner and outer walls of the skirt base 100.

[0054] For example, the three mounting positions 130 form an equilateral triangle.

[0055] Continue as Figure 1 As shown, the support unit 200 includes three support frames 210, which are disposed within the accommodating space 110 and along the circumference of the skirt 100. The three support frames 210 and three mounting positions 130 are alternately arranged in sequence. Both ends of each support frame 210 are detachably connected to the corresponding mounting position 130, allowing each support frame 210 to be completely removed from the skirt 100 after the vertical equipment is hoisted, facilitating reuse, reducing resource waste, and lowering hoisting costs. Furthermore, the three support frames 210 and the three mounting positions 130 form an equilateral triangle, making the included angle between the three support units 200 also an equilateral triangle, resulting in more even force distribution on the three support frames 210 and greater stability of the support unit 200.

[0056] Furthermore, the support frame 210 includes a connecting mechanism 211 and two fixing members 212. The two fixing members 212 are arranged opposite each other along the extension direction of the support frame 210. The connecting mechanism 211 is disposed between the two fixing members 212 and is detachably connected to each of the two fixing members 212, allowing the support frame 210 to be installed or disassembled separately. A channel hole is provided on the skirt 100, further facilitating the installation or disassembly of the support frame 210 and making it easier for the fixing members 212 and the connecting mechanism 211 to move in or out of the channel hole. The connection position between the connecting mechanism 211 and at least one of the two fixing members 212 is adjustable, allowing the length of the support frame 210 to be adjustable. This enables the same support frame 210 to be applicable to skirts 100 or vertical equipment of different sizes, thereby improving the applicability and versatility of each support frame 210. Of course, when the size of the vertical equipment changes significantly, the maximum length of the support frame 210 can be satisfied by replacing the connecting mechanism 211 or the fixing member 212 with a corresponding length.

[0057] In summary, in this embodiment, on the one hand, by setting the support unit 200 in the accommodating space 110 within the skirt 100, during the hoisting process, the support unit 200 and the skirt 100 together bear the force transmitted from the lifting lug 120, thereby avoiding the force being entirely borne by the skirt 100, reducing the magnitude of the force on the skirt 100, and thus reducing the deformation of the skirt 100, improving the hoisting reliability of the vertical equipment using the support device 10;

[0058] Secondly, by setting three support frames 210 in the support unit 200, and all three support frames 210 can be detachably connected to the skirt 100, the support unit 200 can be completely removed from the skirt 100 after hoisting, so as to be reused, thereby reducing material waste and lowering hoisting costs.

[0059] Thirdly, by providing two fixing members 212 and a connecting mechanism 211 in each support frame 210, each support frame 210 has multiple connection positions. These multiple connection positions can work together to bear force, thereby distributing the torque on the support frame 210 to multiple connection positions, thus improving the support reliability of each support frame 210. Furthermore, the connection position between the connecting mechanism 211 and at least one of the two fixing members 212 is adjustable, so that the length of the support frame 210 is adjustable. This allows the same support frame 210 to be applied to skirt bases 100 and vertical equipment of different sizes, thereby improving the applicability and versatility of the support unit 200.

[0060] In some specific embodiments, the adjustable connection position between the connecting mechanism 211 and the two fixing members 212 is achieved as follows:

[0061] like Figure 1 and Figure 2 As shown, the connecting mechanism 211 includes a threaded connector 2111, with first external threads 2114 at both ends. Two fixing members 212 have threaded holes 2121 that match the first external threads 2114. The threaded connector 2111 and the fixing members 212 are threadedly engaged so that the distance between the two fixing members 212 is adjustable, thereby making the length of each support frame 210 adjustable to suit different sizes of skirt 100 and vertical equipment, thereby improving the applicability and versatility of the support unit 200.

[0062] For example, such as Figure 2 As shown, the threaded connector 2111 is a shaft-shaped component with a first external thread 2114 at both ends.

[0063] Furthermore, such as Figure 1 and Figure 3As shown, the connecting mechanism 211 also includes a plurality of first fasteners 2113. The plurality of first fasteners 2113 are arranged at intervals along the circumference of the threaded connector 2111, and the two ends of each first fastener 2113 are detachably connected to the corresponding fixing member 212. The setting of the first fasteners 2113 enhances the connection strength between the connecting mechanism 211 and the fixing member 212, thereby improving the connection strength of each support frame 210 and thus improving the support reliability of the support device 10.

[0064] An example, such as Figure 3 As shown, the first fastener 2113 is a shaft-shaped member with a second external thread 2115 at both ends. The number of the first fasteners 2113 is greater than or equal to four. Specifically, the number of the first fasteners 2113 can be four, six, eight, ten, etc. In this embodiment, the number of the first fasteners 2113 is four as an example for illustration.

[0065] For example, each of the two fasteners 212 has four through holes at corresponding positions. After the threaded connector 2111 is fixed relative to the two corresponding fasteners 212, the first fastener 2113 passes through the corresponding through holes of the two fasteners 212 and is fixedly connected to the corresponding fastener 212 by using nuts. Specifically, nuts and first fasteners 2113 can be provided on both sides of each through hole to further strengthen the connection strength between the connecting mechanism 211 and the fasteners 212, thereby improving the support reliability of the support device 10.

[0066] In addition, such as Figure 2 As shown, the threaded connector 2111 has a limiting structure 2112 on its peripheral wall, and along the axial direction of the threaded connector 2111, the projection of the limiting structure 2112 covers the projection of the threaded hole 2121. That is, the radial dimension of the limiting structure 2112 on the threaded connector 2111 is greater than the diameter of the threaded hole 2121, thereby limiting the connection position between the threaded connector 2111 and the fixing member 212, and avoiding excessive rotation of the threaded connector 2111 relative to the fixing member 212, so that the threaded connector 2111 is completely inserted into the fixing member 212 on one side.

[0067] For example, the limiting structure 2112 is a limiting protrusion, including but not limited to circular protrusions, square protrusions, polygonal protrusions, etc. Specifically, the limiting structure 2112 is a hexagonal protrusion or a hexagonal protrusion. While enabling the threaded connector 2111 to limit the relative position of the fixing member 212, it also cooperates with the wrench to increase the force-bearing area between the wrench and the limiting structure 2112, so as to drive the limiting structure 2112 to rotate relative to the fixing member 212 with less effort, thereby adjusting the distance between the two fixing members 212, so that the length of each support frame 210 is adjustable.

[0068] Furthermore, such as Figure 4 , Figure 5 and Figure 6 As shown, the fastener 212 includes at least two first fixing plates 2122, a connecting pipe 2123, and a second fixing plate 2124. The at least two first fixing plates 2122 are spaced apart along the extension direction of the support frame 210, and the connecting pipe 2123 connects two adjacent first fixing plates 2122. The second fixing plate 2124 is perpendicular to the first fixing plate 2122 on the side away from the connecting mechanism 211 and is fixedly connected. The second fixing plate 2124 is detachably connected to the mounting position 130.

[0069] For example, the number of first fixing plates 2122 can be two, three, four, etc. This embodiment of the application takes two first fixing plates 2122 as an example, with the two first fixing plates 2122 respectively disposed at both ends of the connecting pipe 2123. Wherein, as Figure 6 As shown, a threaded hole 2121 is provided on the first fixing plate 2122 near the connecting mechanism 211 to facilitate an adjustable threaded connection with the threaded connector 2111; and a through hole is also provided on the first fixing plate 2122 near the connecting mechanism 211 to facilitate a detachable connection with the first fastener 2113.

[0070] In another example, the first fixing plate 2122 and the connecting pipe 2123 are fixedly connected, and the first fixing plate 2122 and the second fixing plate 2124 on the side away from the connecting mechanism 211 are fixedly connected. The fixed connection can be welded, glued, snap-fitted, etc.

[0071] Furthermore, in some embodiments, the four corners of the first fixing plate 2122 are rounded to prevent the fixing member 212 from bumping against the channel hole when it moves in or out of the channel hole.

[0072] In addition, combined Figure 1 and Figure 4 As shown, the support frame 210 also includes a plurality of second fasteners 213. Each second fixing plate 2124 has two first elongated holes 2125. The second fasteners 213 pass through the first elongated holes 2125 and are detachably connected to the corresponding mounting positions 130, so that each support frame 210 can be completely removed from the skirt 100 for reuse, thereby reducing material waste and lowering hoisting costs.

[0073] For example, the second fastener 213 can be a bolt or nut, and the number of the second fasteners 213 can be two, three, four, five, six, etc.

[0074] The first elongated hole 2125 on the second fixing plate 2124 is arranged such that the length direction of the first elongated hole 2125 is consistent with the length extension direction of the support frame 210. This allows the second fixing plate 2124 to make a slight displacement relative to the mounting position 130 during the connection process between the second fixing plate 2124 and the mounting position 130. This provides a pre-installation adjustment space for the support frame 210 before the connecting mechanism 211 and the fixing member 212 are tightened, facilitating the pre-setting of the support frame 210.

[0075] like Figure 7 , Figure 8 and Figure 9 As shown, mounting position 130 has a mounting plate 131. The contour of the mounting plate 131 facing the inner wall of the skirt 100 matches the contour of the inner wall of the skirt 100. Each second fixing plate 2124 is detachably connected to the corresponding mounting plate 131 by a second fastener 213. The mounting plate 131 increases the connection area between the mounting position 130 and the second fixing plate 2124, improves the connection strength between the skirt 100 and the support frame 210, and thus improves the support reliability of the support device 10.

[0076] Of course, such as Figure 7 As shown, the mounting plate 131 has a first through hole 1311 corresponding to the position of the first elongated hole 2125 on the second fixing plate 2124, so that the second fastener 213 can pass through the first elongated hole 2125 and the first through hole 1311 to fix the mounting plate 131 to the second fixing plate 2124.

[0077] In addition, such as Figure 10 As shown, an anti-slip element 400 is provided between the mounting plate 131 and the second fixing plate 2124. For example, the anti-slip element 400 can be an aluminum sheet to increase the friction between the mounting plate 131 and the second fixing plate 2124, improve the connection strength between the two, and thus improve the support reliability of the support frame 210.

[0078] Furthermore, in combination Figure 1 and Figure 9 As shown, a reinforcing plate 132 is also provided at the mounting position 130. The outline of the reinforcing plate 132 matches the outline of the inner wall surface of the skirt 100. The reinforcing plate 132 connects the mounting plate 131 and the mounting position 130. The setting of the reinforcing plate 132 increases the contact area between the mounting plate 131 and the mounting position 130, that is, increases the force-bearing area for force transmission between the support frame 210 and the lifting lug 120. This makes it easier for the force transmitted from the lifting lug 120 to be transmitted to the support frame 210, thereby further reducing the magnitude of the force on the skirt 100 and improving the support reliability of the support device 10.

[0079] For example, the mounting plate 131 and the reinforcing plate 132 are arranged vertically, and the mounting plate 131 and the reinforcing plate 132 are fixedly connected. The fixed connection can be achieved by welding, bonding, snap-fit ​​connection, etc.

[0080] In some embodiments, the support device 10 further includes three sets of fastening units, and each reinforcing plate 132 is detachably connected to the mounting position 130 via a set of fastening units. Specifically, as shown in the figure... Figure 9 As shown, the reinforcing plate 132 has a second elongated hole 1321, and each mounting position 130 has a second through hole at a corresponding position. The fastening unit passes through the second elongated hole 1321 and the second through hole to fix the reinforcing plate 132 to the skirt 100. The reinforcing plate 132 and the mounting position 130 are detachably connected, allowing the reinforcing plate 132 and mounting plate 131 to be completely removed from the skirt 100. This facilitates the reuse of the reinforcing plate 132 and mounting plate 131, reduces material waste, and lowers hoisting costs.

[0081] Furthermore, the fastening unit includes two sets of third fasteners 300, with the lifting lug 120 positioned between the two sets of third fasteners 300. (Combined) Figure 1 and Figure 9 As shown, the third fastener 300 can be a bolt and nut connector. Each group of third fasteners 300 includes two bolt and nut connectors. Therefore, each fastening unit includes four bolt and nut connectors. The four bolt and nut connectors are arranged in pairs on both sides of the lifting lug 120, so that the force transmitted from the lifting lug 120 can be evenly distributed from the left and right sides to the support unit 200, thereby avoiding the phenomenon of excessive local stress on the support unit 200 and improving the support reliability of the support device 10.

[0082] In some embodiments, the nominal diameter of the threaded connector 2111 is greater than or equal to 50 mm;

[0083] The nominal diameter of the first fastener 2113 is greater than or equal to 20mm;

[0084] The threaded connector 2111 and the first fastener 2113 can be made of 16 manganese steel (16Mn) or low alloy high-strength structural steel (Q345D).

[0085] The thickness of the first fixing plate 2122 is greater than or equal to 30mm;

[0086] The thickness of the second fixing plate 2124 is greater than or equal to 20mm;

[0087] The nominal diameter of the connecting pipe 2123 can be 200mm, the thickness of the connecting pipe 2123 is greater than or equal to 8mm, and the material of the connecting pipe 2123 can be low alloy high strength structural steel (Q345D).

[0088] The thickness of the reinforcing plate 132 and the connecting plate is greater than or equal to 20mm, and the material can be low alloy high strength structural steel (Q345D).

[0089] The nominal diameter of the second fastener 213 and the third fastener 300 is greater than or equal to 48 mm.

[0090] In addition, the installation process of the support unit 200 in the skirt 100 is as follows:

[0091] First, the three mounting plates 131 and reinforcing plates 132 are assembled and installed onto the three mounting positions 130 using three sets of fastening units. Second, the two fixing members 212 are pre-fixed using threaded connectors 2111, and the three support frames 210 are placed on the mounting plates 131. The threaded connectors 2111 are adjusted so that the first elongated hole 2125 on the second fixing plate 2124 in the support frame 210 corresponds to the first through hole 1311 on the mounting plate 131. The second fixing plate 2124 is pre-connected to the mounting plate 131 using the second fastener 213. Then, the threaded connectors 2111 are rotated to increase the distance between the two fixing members 212 until the first fixing plate 2122, which is away from the connecting mechanism 211, is completely abutted against the mounting plate 131. The second fastener 213 is then tightened. Finally, the first fastener 2113 is installed between the two fixing members 212 to strengthen the connection between the connecting mechanism 211 and the fixing members 212, and the threaded connectors 2111 are adjusted again.

[0092] The process of removing the support unit 200 from the skirt 100 is the reverse of its installation process: First, remove the first fastener 2113 from the corresponding fixing member 212; second, loosen each of the second fasteners 213, adjust the threaded connector 2111, release the abutment between the corresponding fixing member 212 and the mounting plate 131, then completely remove the second fasteners 213, and then remove the support frame 210 from the mounting plate 131; then, remove the combination of the three mounting plates 131 and the reinforcing plate 132 from each mounting position 130.

[0093] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments" used in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not all embodiments necessarily include that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0094] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0095] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0096] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
