Description

Technical Field

[0001] This application belongs to the field of prefabricated large-span building technology, and more specifically, it relates to a hub platform load-bearing frame. Background Technology

[0002] With the development of aerospace and astronomical technologies, low-altitude aircraft are becoming increasingly common. These aircraft require hub platforms, which places a heavy burden on land use. To conserve land, hub platforms need to be built above roads or other infrastructure to achieve comprehensive utilization of ground space. Furthermore, due to limitations imposed by terrain and geological conditions, portal frame structures are required for support when constructing these hub platforms.

[0003] While long-span bridges are not uncommon, they typically only provide long, narrow usable platforms, not platforms with unrestricted width and unobstructed access. If a platform is constructed with both long and wide spans, the only viable option for a portal frame is to increase the cross-sections of beams and columns to enhance support strength. This not only wastes building materials but also increases the space required for the beams and columns, posing safety hazards. Utility Model Content

[0004] The purpose of this application is to provide a load-bearing frame for a hub platform, so as to solve the technical problem that the load-bearing frame in the prior art can only increase the support strength by increasing the cross-sectional area of ​​the beams and columns to adapt to large-span hub platforms.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a hub platform support frame, comprising: Gatepost; The horizontal beam connects to the doorpost to form a door-shaped frame; Guide pulleys are installed on the portal frame, and guide pulleys are respectively provided on the left and right sides of the flat beam; The pull cable has its two ends passing over the guide pulleys on the corresponding sides and connected to the bottom of the gateposts on the corresponding sides, so that a portion of the pull cable is suspended below the flat beam; The support arm is vertically arranged, with its top end fixedly connected to the flat beam and its bottom end slidably connected to the suspension portion of the pull cable.

[0006] Optionally, a plurality of guide pulleys are installed on the same side of the flat beam, and at least two of the guide pulleys are staggered in both the horizontal and vertical directions.

[0007] Optionally, a support arch is installed at the connection between the gatepost and the flat beam, and the guide pulley is installed on the support arch; Alternatively, a support rod may be provided between the flat beam and the gatepost, and guide pulleys may be installed on both the gatepost and the flat beam.

[0008] Optionally, the hub platform support frame further includes a cable sleeve, the lower cable passes through the cable sleeve and can move axially within the cable sleeve, and the bottom end of the support arm is fixedly connected to the cable sleeve; Alternatively, the hub platform support frame may further include a cable pulley, which is rotatably mounted at the bottom end of the support arm and has a groove extending circumferentially, in which the lower cable is accommodated.

[0009] Optionally, multiple gateposts are arranged on opposite sides of the flat beam, and two adjacent gateposts on the same side of the flat beam are connected by a truss beam and a diagonal brace. And / or, the gateposts are arranged in multiple rows, and the two ends of the flat beam are connected to two gateposts located in the same row, or, at least partially, one end of the flat beam is simultaneously connected to multiple gateposts in different rows.

[0010] Optionally, the hub platform support frame also includes an electric hoist, with the electric hoist installed on the left and right sides of the flat beam, the electric hoist being fixed to the bottom of the corresponding gatepost, and the pull cable being connected to the winch of the electric hoist; And / or, a locking seat is fitted and fixed to the end of the pull cable, and the locking seat is connected to the bottom of the door post.

[0011] Optionally, the locking seat has a first cable through hole extending vertically and a first locking hole extending laterally and communicating with the first cable through hole. The pull cable passes through the first cable through hole, and the first locking member passes through the first locking hole and abuts against the pull cable to press and fix the pull cable on the locking seat.

[0012] Optionally, the hub platform support frame further includes an end locking block, which is fixed to the end of the pull cable.

[0013] Optionally, the hub platform support frame also includes an upper cable, and two support arm connecting columns are fixedly connected to the flat beam. An upper cable is installed between each support arm connecting column and the adjacent gate column.

[0014] Optionally, the pull cable is fitted with a flame-retardant tube.

[0015] The beneficial effects of the hub platform load-bearing frame provided in this application are as follows: Compared with the prior art, this application increases the span of the portal frame load-bearing frame by setting the down cable under the flat beam and the support arms distributed between the flat beam and the down cable, creating conditions for constructing a large-span platform. Moreover, the portal frame does not need to be equipped with tie and support components like cable-stayed bridges, forming an unobstructed plane and reducing the space occupied.

[0072] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0073] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0074] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0075] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0076] Example 1 See Figures 1 to 34 As shown in the illustration, an embodiment of this application provides a hub platform support frame, including a portal column 10, a horizontal beam 20, a guide pulley 30, a pulley cable 40, and a support arm 50. (See also...) Figures 1 to 3The gateposts 10 and the horizontal beam 20 are connected to form a gate-shaped frame. Guide pulleys 30 are installed on the gate-shaped frame, with guide pulleys 30 on both the left and right sides of the horizontal beam 20. The two ends of the pull-down cable 40 pass over the guide pulleys 30 on the corresponding sides and are connected to the bottom of the gateposts 10 on the corresponding sides, so that a portion of the pull-down cable 40 is suspended below the horizontal beam 20. (See reference...) Figure 2 The top end of the support arm 50 is fixedly connected to the flat beam 20, and the bottom end of the support arm 50 is slidably connected to the suspended portion of the lower cable 40. The hub platform load-bearing frame provided in this embodiment increases the span of the portal frame through the lower cable 40 set below the flat beam 20 and the support arms 50 distributed between the flat beam 20 and the lower cable 40, creating conditions for constructing a large-span platform. Moreover, the upper part of the portal frame does not need to be equipped with tie rods, supports and other components like those in a cable-stayed bridge, forming an unobstructed plane and reducing the space occupied.

[0077] Among them, see Figure 1 The goalposts 10 are arranged in a double-row, four-poster-per-row configuration. (See reference...) Figure 3 A horizontal beam 20 is installed between the two middle gateposts 10 in the same row. Therefore, a total of two horizontal beams 20 are required for both rows of gateposts 10. (See also...) Figure 5 Two portal columns 10 located on the same side of the horizontal beam 20 in the same row are connected by a truss beam 60 and a diagonal brace 61. Truss connecting ends 600 are provided at both ends of the truss beam 60, and are fitted onto both ends of the truss beam 60 and fixed with bolts. (See reference...) Figure 6 The truss connection end 600 has a snap-fit ​​groove 601 and bolt-connection reinforcing plates 602 located on both sides of the snap-fit ​​groove 601. The snap-fit ​​groove 601 of the truss connection end 600 snaps onto the protruding end of the gatepost 10 and is fixedly connected to the gatepost 10 by the bolt-connection reinforcing plates 602. The two ends of the diagonal brace 61 are fixedly connected to the truss beam 60 through the connection end.

[0078] See Figure 7 Both ends of the first connecting rod 612 and the second connecting rod 613 are hinged to connecting rod hinge seats 614. Specifically, both the first connecting rod 612 and the second connecting rod 613 have hinge holes, and the first connecting rod 612 and the second connecting rod 613 are hinged to the connecting rod hinge seats 614 via hinge pins passing through the hinge holes. The connecting rod hinge seats 614 are fixed to the truss beams 60. Thus, both ends of the diagonal brace 61 are hinged to the two vertically arranged truss beams 60 via the connecting rod hinge seats 614, and are inclined to the truss beams 60. (See reference...) Figure 8The diagonal brace 61 includes a connecting sleeve 611, a first connecting rod 612, and a second connecting rod 613. The inner wall of the connecting sleeve 611 is provided with positive and negative threads. The first connecting rod 612 connects to the positive thread inside the connecting sleeve 611, and the second connecting rod 613 connects to the negative thread inside the connecting sleeve 611. By adjusting the depth to which the first connecting rod 612 and the second connecting rod 613 are screwed into the connecting sleeve 611, the entire diagonal brace 61 can be adapted to truss beams 60 with different spacing.

[0079] The gatepost 10 includes multiple vertical beams 11 and corner bases 12, with the corner bases 12 surrounding the bottom of the vertical beams 11. For example... Figure 1 As shown, the gatepost 10 includes two vertical beams 11, and the gatepost base is fixed to the outer bottom of the two vertical beams 11 and fixedly connected to the vertical beams 11. Of course, the number of vertical beams 11 can also be three; this application does not specifically limit this. In some embodiments, see [reference needed]. Figure 9 The column base 12 has a mounting groove 121, and the bottom of the vertical beam 11 is inserted into the mounting groove 121 and fixedly connected to the groove wall. In some other embodiments, see [reference needed]. Figure 5 Multiple vertical beams 11 are enclosed and fixed by connecting plates. Multiple connecting plates can be set along the extension direction of the vertical beams 11 to improve the stability of the connection. The column corner bases 12 are triangularly supported on both sides of the overall structure after the multiple vertical beams 11 are connected to improve the bottom support capacity.

[0080] like Figure 10 and Figure 11 As shown, the vertical beam 11 is a rectangular tube, which includes a core column 101, a radial connecting plate 102, and an outer surrounding tube 103. The core column 101 is inserted into the outer surrounding tube 103, and the radial connecting plate connects to the corresponding edges of the core column 101 and the outer surrounding tube 103. Optionally, the radial connecting plate includes a flat plate and two inclined plates disposed on opposite sides of the flat plate. The flat plate is fitted against the outer wall of the core column 101 and fixed with bolts, and the inclined plates connect the corresponding edges of the core column 101 and the outer surrounding tube 103. Figure 11 As shown, two radial connecting plates connect the core post 101 and the outer surrounding tube 103 at the four corners. Multiple top blocks 104 are arranged at intervals and assembled within the grooves formed by two adjacent inclined plates. It should be noted that the two inclined plates can be structures within the same radial connecting plate or structures within two separate radial connecting plates, as long as they are adjacent inclined plates. The outer surrounding tube 103 surrounds the radial connecting plate 102 and the top blocks 104, and the outer surrounding plate 103 is bolted to the top blocks 104 to achieve a fixed connection with the core post 101.

[0081] The top block 104 includes a first plate, a second plate, and a third plate. The first and third plates are arranged in parallel, and the second plate connects the first and third plates, forming an I-shape. The first plate is bolted to the core column 101, and the third plate is bolted to the outer casing tube 103. All three plates are steel plates or other building panels. Optionally, the first, second, and third plates are welded together, with the first plate being smaller than the third plate. Specifically, the second plate is first vertically welded to the first plate. Then, multiple snap-fit ​​protrusions are formed on the side of the second plate away from the first plate. The third plate has multiple connecting slots, with each slot corresponding to a snap-fit ​​protrusion. The snap-fit ​​protrusions are then embedded into the connecting slots and welded together, resolving connection issues caused by positional interference.

[0082] See Figure 4 and Figure 12 The horizontal beam 20 is a cross-braced truss, including a first upper horizontal beam 211, a first lower horizontal beam 212, a first vertical support column 213, and a first truss diagonal brace 214. Multiple first vertical supports 213 are arranged between the first upper horizontal beam 211 and the first lower horizontal beam 212. (See reference...) Figure 15 The first truss diagonal brace 214 is supported within the square frame formed by the first upper crossbeam 211, the first lower crossbeam 212, and two adjacent first vertical supports 213. (See also...) Figure 13 and Figure 14 The two ends of the first upper crossbeam 211 and the first lower crossbeam 212 are respectively fixed to the gatepost 10 through the first crossbeam connecting end 219. The specific structure of the first crossbeam connecting end 219 is the same as that of the truss connecting end 600, and will not be described again. Both the first upper crossbeam 211 and the first lower crossbeam 212 are rectangular tubes. The specific structure of the rectangular tubes is described above, and will not be described again.

[0083] Multiple first vertical support columns 213 are evenly distributed between the first upper crossbeam 211 and the first lower crossbeam 212. The two ends of each first vertical support column 213 are fixed to the first upper crossbeam 211 and the first lower crossbeam 212 via right-angle connectors. (See reference...) Figure 16The first truss diagonal brace 214 includes a continuous column 215 and two spliced ​​columns 216. The two spliced ​​columns 216 are located on opposite sides of the continuous column 215, and the continuous column 215 and the two spliced ​​columns 216 are connected to form an X-shape. One end of the continuous column 215 is sleeved with a first connecting end 217 and is fixed to the first vertical support 213 and the first upper crossbeam 211 by means of the first connecting end 217. The other end is sleeved with another first connecting end 217 and is fixed to the adjacent first vertical support 213 and the first lower crossbeam 212 by means of the first connecting end 217. One end of each of the two splicing rods 216 is respectively fitted with a second connecting end 218 and fixed to a protrusion in the middle of the through rod 215 via a corresponding first connecting end 217. The other end of one splicing rod 216 is fitted with the first connecting end 217 and fixed to the first vertical support 213 and the first upper crossbeam 211 via the first connecting end 217. The other end of the other splicing rod 216 is fitted with the first connecting end 217 and fixed to the first vertical support 213 and the first lower crossbeam 212 via the first connecting end 217. (See reference...) Figure 17 The first connecting end 217 has two sets of first connecting plates 2171, one set of which is parallel to the first upper crossbeam 211, and the other set is perpendicular to the first upper crossbeam 211, so as to be fixedly connected to the corresponding beam by bolts. (See reference...) Figure 18 The second connecting end 218 has a slot plate and a reinforcing plate connected to the slot plate, the slot plate having a slot ( Figure 18 (Not shown in the image) The slot is engaged with the protrusion in the middle of the through rod post 215. A second connecting plate 2181 is provided on both sides of the slot, and the second connecting plate 2181 is bolted to the through rod post 215.

[0084] Guide pulleys 30 are used to adjust the direction of the pulley cable 40. Optionally, multiple guide pulleys 30 are installed on the same side of the flat beam 20, with at least two of the guide pulleys 30 staggered in both the horizontal and vertical directions. For example, see... Figure 19 Two guide pulleys 30 are provided on the left and right sides of the flat beam 20, and the two guide pulleys 30 are staggered in both the horizontal and vertical directions.

[0085] See Figure 4 In this embodiment, a support arch 70 is installed on the gatepost 10, and a guide pulley 30 is installed on the support arch 70. The support arch 70 can improve the support strength between the pull cable 40 and the gatepost 10.

[0086] See Figure 20The arch support 70 includes truss arch beams 71 and an outer arch plate 72. Multiple truss arch beams 71 of varying lengths are fixed to the gatepost 10 in a manner that decreases in length from top to bottom. The outer arch plate 72 surrounds the truss arch beams 71. Optionally, the number of truss arch beams 71 is at least three to improve the stability of the entire load-bearing frame.

[0087] See Figure 20 The arch support 70 includes three truss arch beams 71 whose length decreases sequentially from top to bottom, and an outer arch plate 72 surrounding the three truss arch beams 71. Each truss arch beam 71 has an arch connecting end 73 fitted to its tail end, and the truss arch beam 71 is fixedly connected to the gatepost 10 via the arch connecting end 73. The structure of the arch connecting end 73 is the same as that of the crossbeam connecting end, and will not be described again. The outer arch plate 72 is U-shaped, covering the three truss arch beams 71 and fixedly connected to them with bolts, thus connecting the truss arch beams 71 and the outer arch plate 72 into a single unit. Guide pulleys 30 are installed on the outer arch plate 72, with two guide pulleys 30 arranged vertically and staggered horizontally. A pull cable 40 passes over the two guide pulleys 30 and connects to a locking seat 41 located below the arch support 70. Optionally, the truss-supported arch beam 71 is a rectangular tube, and the specific structure of the rectangular tube is described above.

[0088] In some alternative embodiments, the pull cable 40 is a steel wire rope. See also... Figure 1 There are four pull cables 40, with two pull cables 40 on each row of gateposts 10. Of course, only one pull cable 40 can be installed on each row of gateposts 10, in which case a total of two pull cables 40 are installed on both rows of gateposts 10. In addition, three pull cables 40 can be installed on each row of gateposts 10. This application does not specifically limit the number of pull cables 40 installed on a single row of gateposts 10.

[0089] See Figure 2 and Figure 3 The hub platform support frame also includes a cable sleeve 80, a lower cable 40 passing through the cable sleeve 80 and being able to move axially within the cable sleeve 80, and the bottom end of the support arm 50 being fixedly connected to the cable sleeve 80.

[0090] See Figure 12 The outrigger 50 includes an outrigger body 501 and an outrigger connecting seat 502. The top end of the outrigger body 501 is fixedly connected to the flat beam 20 by bolts, and the bottom end of the outrigger body 501 is fixedly connected to the outrigger connecting seat 502. (See reference...) Figure 21 and Figure 22 The outrigger connector 502 has an end sleeve 503, and the two ends of the cable sleeve 80 are inserted and fixed in the end sleeve 503 on the corresponding side.

[0091] Specifically, the outrigger connector 502 is wrapped around the bottom of the outrigger body 501 with tubing on all four sides, and the top of the outrigger body 501 is fixedly connected to the flat beam 20 with angle iron bolts. (See reference...) Figure 24 The inner wall of the end sleeve 503 has a stepped surface, and the end of the cable sleeve 80 abuts against the stepped surface, thereby constraining the lateral position of the cable sleeve 80.

[0092] When only one pull cable 40 is installed on a single row of goalposts 10, refer to Figure 12 A corresponding end sleeve 503 can be installed on the outrigger connector 502. (See reference...) Figure 21 and Figure 22 When two pull cables 40 are provided on a single row of gateposts 10, two end sleeves 503 are provided on the arm connecting seat 502.

[0093] The lower cable 40 can slide along the axial direction of the cable sleeve 80 within the cable sleeve 80. Optionally, see [reference needed]. Figure 23 and Figure 24 A lubricating ring 401 is fitted onto the portion of the lower cable 40 located inside the cable sleeve 80. The lubricating ring 401 is positioned between the inner wall of the cable sleeve 80 and the lower cable 40 to reduce friction between them. Optionally, the lubricating ring 401 is a rubber ring. (See also...) Figure 24 Multiple lubrication rings 401 are spaced apart on the pull cable 40.

[0094] See Figure 26 The lower cable 40 is also fitted with a flame-retardant tube 810 to prevent it from being exposed to air. The flame-retardant tube 810 improves the fire resistance of the lower cable 40 and extends its service life, preventing the lower cable 40 from failing in the event of a fire and reducing the strength of the entire hub platform's load-bearing frame. Understandably, because the lower cable 40 is segmented by the support arm 50, the cable sleeve 80, and the guide pulley 30, therefore, see [reference needed] Figure 27 Each section of the pull cable 40 is provided with a flame-retardant tube 810, and the two sections of flame-retardant tube 810 are connected by a bent sleeve. In some embodiments, the portion of the pull cable 40 located inside the cable sleeve 80 is not provided with a flame-retardant tube 810, and the lubrication ring 401 is directly sleeved on the pull cable 40. In other embodiments, the portion of the pull cable 40 located inside the cable sleeve 80 is also provided with a flame-retardant tube 810, and the lubrication ring 401 can be sleeved inside the flame-retardant tube 810. The flame-retardant tube 810 is made of flame-retardant material and covers the outside of the pull cable 40 to form a tight fit. For the size of the flame-retardant tube 810, please refer to [reference needed]. Figure 24 The interior of the end sleeve 503 is stepped, and its stepped surface abuts against the end face of the cable sleeve. The large end is adapted to the curved sleeve.

[0095] See Figure 25and Figure 26 The load-bearing frame of the hub platform also includes electric hoists 90. Electric hoists 90 are respectively installed on the left and right sides of the flat beam 20. The electric hoists 90 are fixed to the bottom of the corresponding gatepost 10. The pull cable 40 is connected to the winch of the electric hoist 90. And / or, the end of the pull cable 40 is fitted with a locking seat 41, which is connected to the bottom of the gatepost 10.

[0096] The locking seat 41 is used to lock the end of the pull cable 40, facilitating its fixation. The locking seat 41 is connected to the gatepost 10 via an electric hoist 90 or other fixing structure. The electric hoist 90 is installed at the bottom of the gatepost 10 and connected to the pull cable 40, thereby fixing the end position of the pull cable 40. It should be noted that the end of the pull cable 40 can be directly connected to the foundation, achieving connection to the bottom of the gatepost 10 via the foundation; alternatively, it can be connected to the bottom of the gatepost 10 via the electric hoist 90 fixed to the bottom of the gatepost 10. It is understood that the hub platform support frame can be equipped with both the electric hoist 90 and the locking seat 41. (See reference...) Figure 25 The pull cable 40 has locking seats 41 connected to both ends. An electric hoist 90 is fixedly installed at the bottom of the gatepost 10, and a hook 91 is installed on the locking seat 41. The hook 91 is connected to the winch in the corresponding electric hoist 90 via a traction rope. Thus, the pull cable 40 is connected to the gatepost 10 via the electric hoists 90 installed on the two gateposts 10. It should be noted that the electric hoist 90 can be directly fixed to the bottom of the gatepost 10, or it can be indirectly fixed using the construction ground.

[0097] The locking seat 41 has a first cable through hole 411 extending vertically and a first locking hole 412 extending laterally and communicating with the first cable through hole 411. The pull cable 40 passes through the first cable through hole 411, and the first locking member 413 passes through the first locking hole 412 and abuts against the pull cable 40 to press and fix the pull cable 40 onto the locking seat 41.

[0098] See Figure 28 and Figure 29 The locking seat 41 includes a cable locking block 414 and an outer locking plate 415. The cable locking block 414 is fitted onto the pull cable 40, and the outer locking plate 415 surrounds the cable locking block 414. A hook 91 is hinged to the outer locking plate 415. Optionally, the outer locking plate 415 is U-shaped, and the cable locking block 414 is housed within the U-shaped space. To prevent friction between the outer locking plate 415 and the pull cable 40, a rubber ring is installed on the portion of the pull cable 40 located inside the outer locking plate 415. The rubber ring is located between the top of the cable locking block 414 and the U-shaped bottom wall of the outer locking plate 415.

[0099] Both the first cable through hole 411 and the first locking hole 412 are located on the cable locking block 414. The cable locking block 414 has a vertically extending first cable through hole 411 for the pull cable 40 to pass through. The four walls of the cable locking block 414 have horizontally extending first locking holes 412 that connect to the first cable through hole 411. After the pull cable 40 passes through the first cable through hole 411 on the cable locking block 414, the first locking member 413 screws into the first locking hole 412, securing the pull cable 40 to the cable locking block 414. The outer locking plate 415 has connecting holes on opposite sides of the first locking holes 412 corresponding to the end locking blocks 42. Fasteners such as bolts pass through the connecting holes and the corresponding first locking holes 412 to secure multiple end locking blocks 42 within the outer locking plate 415. To improve connection stability, optionally, the cable locking block 414 is provided with multiple first locking holes 412, which are spaced apart along the axial direction of the first cable through hole 411. (See reference) Figure 29 The cable locking block 414 has three first locking holes 412 along its vertical direction. (See reference...) Figure 30 The cable locking block 414 has two first locking holes 412 along the vertical direction. For easy connection, the four outer walls of the cable locking block 414 are provided with first locking holes 412. On the one hand, this makes it easy to install without distinguishing the installation direction. On the other hand, a first locking element 413 can be installed on the first locking hole 412 on each outer wall to enhance the stability of the connection between the cable and the locking seat 41.

[0100] Multiple cable locking blocks 414 are arranged along the extension direction of the lower cable 40. (See reference...) Figure 30 and Figure 34 Two cable locking blocks 414 are provided along the extension direction of the lower cable 40.

[0101] To prevent the end of the pull cable 40 from loosening, an end locking block 42 is installed at the end of the pull cable 40 for locking. (See reference...) Figure 28 and Figure 30 The outer locking plate 415 can also be installed around the cable locking block 414 and the end locking block 42.

[0102] See Figure 29 Each pull cable 40 has a set of cable locking blocks 414 and end locking blocks 42 at its end. When there are multiple pull cables 40, an outer locking plate 415 is used to cover and secure the multiple cable locking blocks 414. To improve the overall aesthetics, the outer locking plate 415 can conceal the end locking blocks 42. (See reference...) Figure 29There are four pull cables 40, and four corresponding cable locking blocks 414. Correspondingly, there are four end locking blocks 42, and an outer locking plate 415 is used to cover the four cable locking blocks 414 and the four end locking blocks 42. In some embodiments, adjacent cable locking blocks 414 are spaced apart, and each cable locking block 414 has a first locking member 413 on its four walls for four-way fixing. For example, the first locking member 413 is a screw with a nut or a set screw. Alternatively, adjacent cable locking blocks 414 are arranged close together. For details, please refer to [link to documentation]. Figure 32 In two adjacent cable locking blocks 414, the first locking holes 412 opposite each other are locked by using a set screw as the first locking element 413. Other first locking holes 412 in the cable locking blocks 414 can use either a set screw or a screw with a nut. Alternatively, see [link to relevant documentation]. Figure 30 The two adjacent cable locking blocks 414 are connected by an intermediate connector 416. Specifically, the intermediate connector 416 is a screw with positive and negative threads, and its two ends are threaded to the corresponding first locking holes 412 on the cable locking blocks 414.

[0103] In some embodiments, the method by which the end locking block 42 locks the end of the pull cable 40 is similar to the method by which the pull cable locking block 414 locks the pull cable 40. Specifically, the end locking block 42 has a second pull cable through hole 421 extending vertically for the pull cable 40 to pass through. The end locking block 42 has a second locking hole 422 extending laterally and communicating with the second pull cable through hole 421. After the pull cable 40 passes through the second pull cable through hole 421 on the end locking block 42, the second locking member 423 screws into the second locking hole 422, fixing the pull cable 40 to the end locking block 42. See reference. Figure 29 and Figure 30 The second locking element 423 is a set screw. (See reference...) Figure 33 The second locking element 423 is a screw with a nut. The end locking block 42 is a U-shaped locking head that is locked onto the pull cable 40. In addition, the end locking block 42 and the U-shaped locking head 43 can be set at the same time to provide double security with the help of the locking head 43 and the end locking block 42, so as to adapt to complex working conditions.

[0104] In some other embodiments, see [reference] Figure 31 , Figure 32 and Figure 34The end locking block 42 includes a locking body 425 and a locking cap 426 fixedly installed at the bottom of the locking body 425. The locking body 425 is sleeved and fixed on the pull cable 40. The second pull cable through hole 421 and the second locking hole 422 are both provided on the locking body 425. The way they are fixed to the pull cable 40 is similar to that of the pull cable locking block 414, and will not be described again. Specifically, the locking cap 426 has a conical head 427 along its axis, and a conical hole is opened at the bottom of the locking body 425. The locking cap 426 is fixed to the bottom of the locking body 425 so that the conical head 427 is inserted into the conical hole. The end of the pull cable 40 is forked, and the conical head 427 cooperates with the wall of the conical hole to clamp and fix the forked end of the pull cable 40. The locking cap 426 is fixed to the bottom of the locking body 425 by bolts. The locking body 425 and the locking cap 426 work together to clamp the end of the pull cable 40, thereby improving the anti-derailment level.

[0105] A height sensor is installed on the pull cable 40, and the electric hoist 90 is communicatively connected to the height sensor. Specifically, the height sensor is installed on the locking seat 41, and the electric hoist 90 can adjust the tension of the pull cable 40 based on the height information collected by the height sensor.

[0106] Optionally, in this embodiment, the pull cable 40 is located inside the gatepost 10, and a tie rod or rope connecting the gatepost 10 and the foundation is provided on the outside of the gatepost 10. The tie rod or rope is used to assist the gatepost 10 in overcoming the tension of the pull cable 40.

[0107] Example 2 See Figures 35 to 36 The difference between the hub platform support frame provided in this embodiment and the hub platform support frame provided in Embodiment 1 lies in the arrangement of the gateposts 10. Specifically, in this embodiment, the gateposts 10 are arranged in a single row of four. Similar to Embodiment 1, a horizontal beam 20 is installed between the two central gateposts 10, and the two gateposts 10 located at the same end of the horizontal beam 20 are connected by a truss beam 60 and a diagonal brace 61. Each gatepost 10 includes two vertical beams 11.

[0108] See Figure 35 The end of the pull cable 40 is not equipped with a locking seat 41 and is directly connected to the winch of the electric hoist 90.

[0109] Example 3 See Figures 37 to 38 The difference between the hub platform support frame provided in this embodiment and that in embodiment 2 is that an upper cable 1000 is provided above the flat beam 20.

[0110] See Figure 37Two support arm connecting columns 1001 are fixedly connected to the flat beam 20. Each support arm connecting column 1001 and its adjacent gatepost 10 are connected by an upper cable 1000. The support arm connecting columns 1001 on the same flat beam 20 are connected by a connecting crossbeam. Optionally, the upper cable 1000 is fitted with a sleeve made of flame-retardant material to improve its fire resistance and extend its service life.

[0111] The base of the outrigger connecting post 1001 is connected to the horizontal beam 20 via the outrigger enclosure plate 1002. The outrigger enclosure plate 1002 includes vertical and horizontal plates, which are bolted to the bottom of the outrigger connecting post 1001 and the horizontal beam 20 respectively, thereby fixing the outrigger connecting post 1001 to the horizontal beam 20. One end of the upper cable 1000 is connected to the top of the outrigger connecting post 1001, and the other end is connected to the gatepost 10 on which the horizontal beam 20 is installed. For details, please refer to... Figure 38 The two ends of the upper cable 1000 are respectively hinged to the doorpost 10 and the support arm connecting post 1001 via a hinge pin connecting seat 1003. Specifically, a hinge pin connecting seat 1003 is fixedly installed on the doorpost 10 and the support arm connecting post 1001, wherein the hinge pin connecting seat 1003 on the support arm connecting post 1001 is higher than the hinge pin connecting seat 1003 on the doorpost 10, and the two ends of the upper cable 1000 are hinged to the two hinge pin connecting seats 1003 in a one-to-one correspondence.

[0112] Example 4 See Figures 39 to 40 The difference between the hub platform support frame provided in this embodiment and Embodiment 3 lies in the arrangement of the gateposts 10. Specifically, in this embodiment, the gateposts 10 are arranged in multiple rows, wherein the installation structure of the horizontal beam 20, the lower cable 40, and the upper cable 1000 in each row of gateposts 10 is the same as in Embodiment 3, and will not be described again.

[0113] See Figure 39 and Figure 40 The gateposts 10 are arranged in a double-row, four-post configuration. A horizontal beam 20 is installed between the two middle gateposts 10 in the same row, thus requiring two horizontal beams 20 for both rows of gateposts 10. The two gateposts 10 on the same side of the horizontal beam 20 in the same row are connected by a truss beam 60 and a diagonal brace 61. Correspondingly, each row of gateposts 10 is equipped with an upper cable 1000, the installation structure of which is the same as in Embodiment 3.

[0114] Example 5 See Figures 41 to 45 The difference between the hub platform support frame provided in this application embodiment and Embodiment 1 is that: the connection relationship between the gatepost 10 and the flat beam 20 is different, the specific structure of the flat beam 20 is different, and the implementation method of the sliding cooperation between the support arm 50 and the pull cable 40 is different.

[0115] For details, please refer to Figure 41 There are two rows of doorposts 10, with two doorposts in each row. The two doorposts 10 located at the same end of the flat beam 20 are arranged side by side and connected to the end of the same flat beam 20. The connection between the front and rear rows of doorposts 10 is achieved by means of the flat beam 20.

[0116] In this embodiment, see Figure 41 and Figure 42 The horizontal beam 20 includes a second upper horizontal beam 221, a second lower horizontal beam 222, a second vertical support column 223, a second truss brace 224, and a first horizontal beam plate 225. The second upper horizontal beam 221 and the second lower horizontal beam 222 are connected by the second vertical support column 223 to form a square column-shaped frame. The ends of the square column-shaped frame are simultaneously connected to two doorposts 10 located at the same end of the horizontal beam 20, thus connecting four doorposts 10 with one square column-shaped frame. The second truss brace 224 is supported within the square frame formed by the vertically arranged second vertical support column 223 and the second upper horizontal beam 221 and second lower horizontal beam 222 arranged vertically. The ends of the second upper horizontal beam 221 and the second lower horizontal beam 222 are respectively connected to the doorposts 10. The first horizontal beam plate 225 is located above the second upper horizontal beam 221, and both ends of the first horizontal beam plate 225 are connected to the doorposts 10.

[0117] See Figure 42 and Figure 43 Two upper crossbeams 221 and two lower crossbeams 222 are provided. Multiple second vertical supports 223 are evenly distributed between the second upper crossbeams 221 and 222, between the two second upper crossbeams 221, and between the two second lower crossbeams 222. The two ends of the second upper crossbeams 221 and 222 are fixed to the gateposts 10 via second crossbeam connecting ends 226. The specific structure of the second crossbeam connecting ends 226 is similar to that of the truss connecting ends 600 and will not be described further. The second vertical supports 223, the first upper crossbeam 211, and the first lower crossbeam 212 are bolted together by T-shaped side panels 227. The two ends of the second truss diagonal brace 224 are bolted together by clothing-shaped side panels 229 and the second upper crossbeam 221, the second lower crossbeam 222, and the second vertical supports 223. Both ends of the first flat beam 225 are fixed to the gatepost 10 via truss connection plugs 228. (See reference) Figure 42 The truss connection plug end 228 is clamped between the two portal posts 10 at the same end of the flat beam 20. (See reference...) Figure 44The first flat beam plate 225 is fitted with a first flat beam plate connecting end 2250 at both ends. The first flat beam plate connecting end 2250 has a socket. The truss connecting plug end 228 has a plug and a door post 10 connecting plate located on the opposite side of the plug. The plug is inserted into the socket. The two door post 10 connecting plates correspond one-to-one with the two door posts 10 on the opposite side of the same end of the flat beam 20 and are bolted together.

[0118] See Figure 44 The first flat beam plate 225 includes a central tube 2251 and a rectangular surrounding sleeve 2252 fitted onto the central tube 2251. The central tube 2251 includes a central square tube 2253, a supporting side plate 2254, and pads 2255. The supporting side plate 2254 connects the central square tube 2253 and the rectangular surrounding sleeve 2252, and divides the cavity between the central square tube 2253 and the rectangular surrounding sleeve 2252 into multiple pad 2255 receiving slots. The pads 2255 are received in the pad 2255 receiving slots and are arranged along the length of the central square tube 2253. One side of the pad 2255 is fixedly connected to the central square tube 2253, and the other side is fixedly connected to the rectangular surrounding sleeve 2252, thereby surrounding the outside of the central tube 2251 with the rectangular surrounding sleeve 2252. The spacer block 2255 is I-shaped. The narrower horizontal plate of the spacer block 2255 is bolted to the outer wall of the central square tube 2253, and the wider horizontal plate of the spacer block 2255 is bolted to the inner wall of the rectangular surrounding sleeve 2252. In some embodiments, the support side plate 2254 is a square plate, and support side plates 2254 are respectively connected to the four edges of the central square tube 2253. The edges of the support side plates 2254 are fixedly connected to the four edges of the inner wall of the rectangular surrounding sleeve 2252. In other embodiments, the support side plate 2254 is a U-shaped plate with an opening that gradually widens from the bottom to the opening. Two support side plates 2254 are fixed to opposite sides of the central square tube 2253. The edges of the support side plates 2254 are fixedly connected to the four sides of the inner wall of the rectangular surrounding sleeve 2252.

[0119] The difference between this embodiment and Embodiment 1 is that, see [link / reference] Figure 43 A rotatable cable pulley 81 is installed at the bottom of the outrigger 50. (See also...) Figure 45 The cable pulley 81 has a groove 811 extending circumferentially, and the lower cable 40 is housed in the groove 811.

[0120] Because of the change in how the bottom of the support arm 50 slides into the pull cable 40, the support arm 50 in this embodiment does not require an end sleeve 503, and its structural form differs from that in Embodiment 1. For details, please refer to... Figure 45The support arm 50 includes two opposing mounting plates 511. The tops of the two mounting plates 511 are fixedly connected to the flat beam 20, creating a gap between the two mounting plates 511. The two ends of the axle are connected to the two mounting plates 511 one-to-one. A cable pulley 81 is positioned within the gap and fitted onto the axle. Optionally, the groove 811 is V-shaped to prevent the pull cable 40 from detaching from the groove 811. Optionally, the cable pulley 81 may have multiple grooves 811. For example, if there are two pull cables 40 on a single row of gateposts 10, two grooves 811 may be arranged in parallel on the cable pulley 81.

[0121] Example 6 See Figures 46 to 52 The difference between the hub platform support frame provided in this application embodiment and embodiment 5 lies in the different specific structure of the flat beam 20, the different installation position of the guide pulley 30, and the different support method between the flat beam 20 and the gatepost 10.

[0122] For details, please refer to Figure 46 The flat beam 20 includes a second flat beam 20 plate and a surrounding flat beam 232 located below the second flat beam 20 plate. The structure of the second flat beam 20 plate is the same as that of the first flat beam plate 225 in Embodiment 2. The ends of the second flat beam 20 plate are connected to two doorposts 10 located on the same side. The surrounding flat beam 232 consists only of two doorposts 10 on both sides in the same row. See reference. Figure 47 There are two rows of gateposts 10, and two side panel beams 232, each corresponding to one of the two rows of gateposts 10. The end of the second side panel beam 20 is connected to both rows of gateposts 10. Specifically, there is no truss connection connector 228 between the two gateposts 10. The inner side of the gatepost 10 has a protrusion, and the two ends of the second side panel beam 20 are respectively fitted with two locking slots on the second side panel beam 20 connection connector, which correspond one-to-one with the protrusions on the two gateposts 10.

[0123] See Figure 47 and Figure 48 The enclosure beam 232 includes a third crossbeam 233 and a reinforcing enclosure plate 234. The two ends of the third crossbeam 233 are fixed to two gateposts 10 in the same row. The reinforcing enclosure plate 234 is fitted onto the third crossbeam 233 and fixedly connected to it. Specifically, the third crossbeam 233 has slots at both ends, and the gateposts 10 have protrusions that insert into the slots. The reinforcing enclosure plate 234 is fixedly connected to the third crossbeam 233 by bolts. A reinforcing connecting plate is integrally formed at the end of the reinforcing enclosure plate 234, with two reinforcing connecting plates located on either side of the slots. The reinforcing connecting plates are bolted to the gateposts 10. A combined steel frame is installed inside the third crossbeam 233 and the second enclosure beam 20.

[0124] See Figure 49The third crossbeam 233 is a rectangular tube. Compared to the rectangular tube in Embodiment 1, this embodiment further includes reinforcing ropes 105. The reinforcing ropes 105 are arranged in a ring at both ends of the core column 101 to enhance the load-bearing capacity of the third crossbeam 233. (See reference...) Figure 50 and Figure 51 The two ends of the reinforcing rope 105 are connected by a rope connecting seat 1051 to form a ring structure. The rope connecting seat 1051 has two third cable through holes 1052 and multiple third locking holes 1053 communicating with the third cable through holes 1052. The axis of the third locking holes 1053 is perpendicular to the axis of the third cable through holes 1052. The two ends of the reinforcing rope 105 pass through the two third cable through holes 1052 respectively. A third locking member 1054 is installed in the third locking holes 1053 to press and fix the two ends of the reinforcing rope 105 onto the rope connecting seat 1051, thereby achieving the connection and fixation of the two ends. (See reference...) Figure 51 To prevent the end of the reinforcing rope 105 from loosening, an end locking block 42 is also provided at the end. The specific structure of the end locking block 42 is described above and will not be repeated here. (See also...) Figure 49 The core column 101 has rope mounting seats 106 at both ends. A reinforcing rope 105 is fitted onto the rope mounting seats 106 at both ends of the core column 101, so that the entire annular reinforcing rope 105 is accommodated within the grooves. To maintain the symmetry of the rectangular tube, a reinforcing rope 105 is accommodated in each of the two opposite grooves. For details, please refer to... Figure 52 The rope mounting base 106 has two mounting wheels 1061, and the mounting wheels 1061 are provided with mounting grooves 1062 for mounting the reinforcing rope 105. The mounting grooves 1062 can be V-shaped or trapezoidal, etc.

[0125] The difference lies in the fact that the arch support 70 is not provided, and a support rod 71 is added between the flat beam 20 and the door post 10. For example... Figure 46 and Figure 47 As shown, two support rods 71 ​​are symmetrically arranged at the edge of the flat beam 20. One end of the support rod 71 is hinged to the bottom edge of the flat beam 20, and the other end is hinged to the doorpost 10. Alternatively, the support rod 71 can also be hinged to the first pulley support 31 and the second pulley support 32, as long as it forms an oblique support between the doorpost 10 and the flat beam 20. The structure of the support rod 71 is the same as that of the oblique brace 61 in Embodiment 1, and will not be described again.

[0126] Accordingly, the installation positions of the two guide pulleys 30 are adjusted. A first pulley support 31 is installed on the gatepost 10, and one of the guide pulleys 30 is installed on the first pulley support 31. A second pulley support 32 is fixedly installed on the side beam 232, and the other guide pulley 30 is installed on the second pulley support 32. This causes the two guide pulleys 30 to be staggered in both the vertical and horizontal directions. The pull cable 40 passes around the two guide pulleys 30 and then connects to the locking seat 41.

[0127] The difference also lies in the specific structural form of the outrigger 50, which differs from that of Embodiment 5. For details, please refer to... Figure 48 The support arm 50 includes a connecting rod 521 and a pulley mounting seat 522 fixed to the bottom of the connecting rod 521. A cable pulley 81 is mounted on the pulley mounting seat 522. The top of the connecting rod 521 is fixedly connected to the flat beam 20. The pulley mounting seat 522 is U-shaped, and the cable pulley 81 is housed within the U-shaped space. It is understood that when the lower cable 40 and the bottom of the support arm 50 achieve sliding engagement via the cable pulley 81, the support arm 50 can also adopt the support arm structure of Embodiment 5; no specific limitation is made in this regard.

[0128] Example 7 See Figure 53 and Figure 54 The difference between the hub platform support frame provided in this application embodiment and embodiment 4 is that: the arrangement of the gateposts 10, the specific structure of the flat beam 20, and the number of cable pulleys 81 and support arms 50 set in groups.

[0129] The gateposts are arranged in a single row of four. A horizontal beam 20 is installed between the two central gateposts 10, and the two gateposts 10 located at the same end of the horizontal beam 20 are connected by a truss crossbeam 60 and a diagonal brace 61. Each gatepost 10 includes a vertical beam 11.

[0130] The specific structure of the flat beam 20 is the same as in Embodiment 1, and will not be described again. The bottom of the support arm 50 and the pulley 40 are slidably connected via pulleys. The specific structure of the support arm 50 is the same as in Embodiment 6. (See also...) Figure 54 There are multiple support arms 50, which are spaced apart along the length of the flat beam 20. Each support arm 50 has a rotatable cable pulley 81 installed at its bottom. The cable pulley 81 has a groove 811 extending in the circumferential direction, and the lower cable 40 is accommodated in the groove 811.

[0131] Optionally, the lengths of the multiple support arms 50 gradually decrease from the center outwards. When there is an odd number of support arms 50, the middle support arm 50 is the longest, gradually decreasing in length from the center outwards. When there is an even number of support arms 50, they are divided into left and right groups, with the lengths of the support arms 50 in the same group gradually decreasing from the center outwards. Two support arms 50 symmetrically positioned from the center outwards have the same length. See also... Figure 53 There are six support arms 50, which are divided into two groups, left and right. The length of the three support arms 50 in the same group gradually decreases from the middle to the sides. The two support arms 50 in the middle are of the same length, the two support arms 50 in the outermost position are of the same length, and the other two support arms 50 are of the same length.

[0132] It should be noted that the structural form of the flat beam 20, the arrangement of the gateposts 10, the sliding engagement between the bottom end of the support arm 50 and the lower cable 40 via the cable pulley 81 or the cable sleeve 80, the specific structure of the support arm 50, and the installation and arrangement of the guide pulley 30 in the above embodiments can be arbitrarily combined, and this application does not make specific limitations in this regard.

[0133] The lateral span of the hub platform's load-bearing frame can reach 24 to 30 meters to provide ample space under the horizontal beam 20 for constructing the hub platform. For example, the span of the hub platform's load-bearing frame can reach 26 meters.

[0134] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
