Description

Technical Field

[0001] This invention relates to the field of space frame structures, and in particular to a self-balancing device for starting a space frame structure. Background Technology

[0002] Frustum-shaped space frames are widely used in storage sheds in cement plants, power plants, and other fields. To create large-span spaces, the structural form adopts a bolted ball joint steel space frame structure. Retaining walls or warehouse walls are set around the material storage sheds, so the space frame supports are mostly set on the retaining walls or warehouse walls. The height of the space frame supports is mostly above +20m. The installation method for this type of steel space frame is mostly high-altitude assembly. However, before the first ring is completed and closed, the structure cannot form a complete force system. The traditional practice is to erect scaffolding as temporary support to complete the first ring installation, and then dismantle the scaffolding to assemble small units on the ground, and then carry out high-altitude assembly. This traditional method has poor balance of space frame components and makes it difficult to ensure the verticality and flatness of the components, resulting in the frustum-shaped space frame having the potential for tilting.

[0003] Therefore, a self-balancing device for starting a space frame is provided to assist in achieving self-balancing coordination of components, thereby stabilizing the starting of a frustum-shaped space frame and reducing the occurrence of tilting. Summary of the Invention

A self-balancing device is installed at the upper end of the retaining wall, and the upper side of the self-balancing device is connected to the steel space frame. The self-balancing device includes a support beam provided at the upper end of the support embedded part, a connecting seat connected to the upper end of the support beam, a support adjustment seat quickly connected to the upper end of the connecting seat, and a support adjustment seat provided inside the connecting seat and connected to the lower end of the support adjustment seat. The assembly includes a locking component, a balance bar connected to the upper end of the support adjustment seat, a quick-connect component located at the upper end of the balance bar, and a spirit level installed on the outer side of the middle part of the balance bar. The quick-connect component includes a horizontal arm located at the upper end of the balance bar, a connecting shell installed inside the right side of the horizontal arm, pressure blocks located on opposite sides inside the horizontal arm, a connecting bar fastened to the inner end of the pressure blocks, a plug rod inserted into the left side of the connecting bar, a connecting plate installed outside the plug rod, a first spring located outside the plug rod, a first rack installed on the plug rod, a gear meshing in the middle of the first rack, a second rack meshing on the right side of the gear, and a pressing structure located inside the right side of the horizontal arm.

[0006] Preferably, the support adjustment seat includes a support seat connected to the upper end of the connecting seat, an adjustment rod rotatably connected inside the support seat, a transmission block tractively connected to the outside of the adjustment rod, a connecting arm connected to the outside of the transmission block, and a turntable located at the upper end of the connecting arm and connected to the lower end of the balance bar.

[0007] Preferably, the locking assembly includes a positioning strip fastened inside the connecting seat, a movable seat built into the left side of the positioning strip, a stop bar rotatably connected to the upper and lower sides of the movable seat, a spring sheet connected between the upper and lower stop bars, a push-pull shaft mated to the left side of the movable seat, a compression spring disposed on the outside of the push-pull shaft, and a first welded pipe and a second welded pipe respectively welded to the outside of the push-pull shaft.

[0008] Preferably, the extrusion structure includes a receiving block built into the right side of the cross arm, guide rods inserted into both ends of the receiving block, and a second spring installed on the outside of the guide rods.

[0009] Preferably, the steel space frame is composed of three steel space frame members, and each adjacent steel space frame member is connected to a bolt ball.

[0010] Preferably, the adjusting rod has an external thread, and the adjusting rod is threadedly connected to the transmission block through the external thread on the outside.

[0011] Preferably, the first welded pipe and the second welded pipe are symmetrically arranged on the left side of the push-pull shaft, and both the first welded pipe and the second welded pipe have external threads on their outer sides.

[0012] Preferably, the plug rod, connecting plate, and first spring are arranged in two sets symmetrically on the left and right, and both sets of connecting plates are plugged into the plug rod.

[0013] The beneficial effects of this invention are:

[0014] This invention incorporates a self-balancing device. A quick-connect assembly at the upper end of the balance bar allows for rapid docking and assembly with one side of the steel space frame, ensuring the steel space frame is installed vertically and self-balanced. The lower end of the balance bar, connected to a support adjustment seat, allows for fine-tuning of the balance bar's tilt when the level bubble on its exterior indicates inclination. This ensures the stability of the self-balancing docking. Furthermore, a locking component inside the connecting seat allows for convenient assembly and disassembly of the self-balancing device, facilitating rapid assembly and disassembly of the steel space frame. This achieves the advantages of convenient docking and self-balancing support for the steel space frame, ensuring stable docking at the beginning of the frame and preventing tilting.

[0015] The installation of supporting beams and connecting seats can form a self-balancing support state, ensuring that the steel space frame is installed vertically.

[0016] The support adjustment seat is designed so that the internal adjustment rod and the transmission block are threaded together, allowing the turntable installed inside the lower end of the balance bar to be driven by the transmission block and the connecting arm, so as to achieve fine adjustment of the balance bar's tilt and ensure the stability of the balance bar's self-balancing effect.

[0017] The setting of the balance bar and the spirit level: the balance bar, which is in a vertical support state, can help to achieve the self-balancing installation of the steel space frame, making the installation of the steel space frame vertical and stable, reducing the installation tilt phenomenon. At the same time, the spirit level can visually determine whether the balance bar is in a vertical state during the self-balancing connection.

[0018] The locking component is designed so that the positioning strip inside can pre-position and align the support base and the connecting base. The push-pull shaft inside the positioning strip allows the moving base to move laterally, causing the abutment bars on the upper and lower sides to automatically unfold and engage with the spring plates installed between them. The first welded tube on the outside of the push-pull shaft is threaded to tighten the abutment bars on both sides against the left side of the support base, achieving a stable locking engagement and keeping the support base firmly locked.

[0019] The quick-connect assembly, consisting of two pressure blocks installed on the right side of the cross arm, provides a closed and blocking fit for the moving steel space frame. In conjunction with the compression structure inside the right side of the cross arm, the receiving block can compress one side of the steel space frame, allowing the steel space frame to be blocked and compressed by the pressure blocks on both sides, achieving a stable connection. This ensures that the balance bar achieves a convenient self-balancing connection with the steel space frame. Furthermore, through the transmission of the first rack, gear, and second rack, the pressure blocks on both sides can be quickly opened, completing the rapid disassembly and separation of the balance bar from the steel space frame.

Detailed Implementation

[0026] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0027] like Figure 1 As shown, the present invention provides a self-balancing device for starting a space frame, including a retaining wall 1, a support embedded part 2 pre-set at the upper end of the retaining wall 1, a steel space frame support 3 welded to the top of the support embedded part 2, a steel space frame 4 set at the upper end of the steel space frame support 3, bolt balls 5 connected to the outside of the steel space frame 4, and a self-balancing device 6 installed at the upper end of the retaining wall 1, and the upper side of the self-balancing device 6 is connected to the steel space frame 4.

[0028] Among them, the steel space frame 4 is composed of three steel space frame members, and each of the two adjacent steel space frame members is connected to the bolt ball 5.

[0029] like Figure 2 As shown, the self-balancing device 6 in this embodiment includes a support beam 61 horizontally welded to the upper end of the support embedded part 2 for auxiliary support, a connecting seat 62 connected to the upper end of the support beam 61 for quick-connect support, a support adjustment seat 63 quickly connected to the upper end of the connecting seat 62, so that the tilting fine adjustment can be achieved through the support beam 61 at the upper end of the support embedded part 2, a locking component 64 inside the connecting seat 62 and connected to the lower end of the support adjustment seat 63, so that the support adjustment seat 63 can be quickly disassembled and assembled, a balance bar 65 vertically connected to the upper end of the support adjustment seat 63, and the balance bar 65 and the upper end of the support adjustment seat 63 rotate together to achieve stable vertical balance support, a quick-connect component 66 installed on the upper end of the balance bar 65 and connected to the outside of the steel grid frame 4, and a level bubble 67 installed on the outer side of the middle of the balance bar 65 for intuitive understanding of vertical balance.

[0030] When performing self-balancing coordination at the beginning of the space frame, pre-welded support pre-embedded parts 2 can be welded at equal intervals on the retaining wall 1, and steel space frame supports 3 can be set on the upper end of the support pre-embedded parts 2. The structure of the steel space frame 4 requires the enclosure of three steel space frame members, and the combination of adjacent steel space frame members can be achieved through bolt balls 5, thereby achieving a stable and firm structure of the steel space frame 4. Then, any bolt ball 5 on the outside of the steel space frame 4 is connected to the steel space frame support 3. When the connection is completed, the balance bar 65 set inside the self-balancing device 6 is quickly connected to the steel space frame 4 through the quick-connect component 66 set at the upper end. At the same time, the support adjustment seat 63 connected to the bottom of the balance bar 65 is also connected to the steel space frame 4. It can quickly connect with the locking component 64 inside the connecting seat 62. In this way, the support beam 61 welded to the upper end of the support embedded part 2 can enable the connecting seat 62, the balance bar 65 and the quick-connect component 66 to achieve self-balancing support for the steel space frame 4 as a whole, so that it is in a stable vertical state, ensuring the stability of the subsequent docking and combination of adjacent steel space frames 4 and reducing the occurrence of tilting. Secondly, the level bubble 67 set in the middle of the outer side of the balance bar 65 can be used to know whether the balance bar 65 provides self-balancing support for the steel space frame 4. If tilting occurs, the tilt adjustment seat 63 can be used to achieve tilt fine adjustment, thereby achieving self-balancing auxiliary cooperation at the beginning of the space frame.

[0031] like Figure 3 As shown, the support adjustment seat 63 in this embodiment includes a support seat 631 embedded inside the upper end of the connecting seat 62 to achieve stable support, an adjustment rod 632 rotatably connected to the inside of the support seat 631, and a transmission block 633 connected to the outside of the adjustment rod 632. The transmission block 633 has a protruding rod integrally fixed in the middle of its front and rear sides. A connecting arm 634 is connected to the outside of the transmission block 633. The connecting arm 634 has a vertical groove in the middle of its front and rear sides. The connecting arm 634 is connected to the protruding rod in the front and rear sides of the transmission block 633 through the vertical groove in the front and rear sides. A turntable 635 is tightly connected to the upper end of the connecting arm 634 and tightly connected to the lower end of the balance bar 65. In this way, when the connecting arm 634 is tilted and swayed by the transmission, the turntable 635 is driven synchronously, thereby realizing the overall tilting and fine adjustment of the balance bar 65.

[0032] Specifically, the adjusting rod 632 has an external thread, and the adjusting rod 632 is threadedly connected to the transmission block 633 through the external thread on the outside, so as to ensure that the adjusting rod 632 can achieve stable lateral reciprocating movement of the transmission block 633 connected to the outside.

[0033] When fine-tuning is required to ensure the stable self-balancing protection of the balance bar 65 with the steel space frame 4, the adjusting rod 632 connected inside the support base 631 can be rotated to make the adjusting rod 632 engage with the external thread, thereby moving the outer threaded transmission block 633 to the left or right. By moving the transmission block 633 left and right, the connecting arm 634 of the external transmission connection can swing. In this way, the turntable 635, which is fastened to the upper end of the connecting arm 634, can swing with the connecting arm 634, thereby realizing the overall tilting fine-tuning of the balance bar 65. The level bubble 67 can be used to visually understand whether the fine-tuning is level, so that the steel space frame 4 is in a stable and balanced state.

[0034] like Figure 4 As shown, the locking component 64 in this embodiment includes a positioning strip 641 that is horizontally fixed inside the connecting seat 62. The positioning strip 641 is inserted into the lower end of the support seat 631 to achieve pre-positioning and mating. The middle part of the positioning strip 641 is hollow, and the upper and lower openings of the positioning strip 641 are inclined and chamfered. A movable seat 642 is movably built into the left side of the positioning strip 641 and can move left and right to engage. Abutment strips 643 are symmetrically rotatably connected to the upper and lower sides of the movable seat 642, and the right ends of the abutment strips 643 abut against the left side of the support seat 631, connecting the upper and lower abutment strips 643. The spring plate 644, in this way, can be used in conjunction with the elastic force of the spring plate 644 to realize the synchronous opposite push-out locking of the two abutment bars 643. It is laterally rotated and connected to the push-pull shaft 645 on the left side of the movable seat 642, and the left end of the abutment bar 643 extends to the outside of the left side of the positioning bar 641. Correspondingly, the compression spring 646 is installed on the outside of the push-pull shaft 645, and the right side of the compression spring 646 is connected to the movable seat 642. The first welded pipe 647 and the second welded pipe 648 are respectively welded to the outside of the push-pull shaft 645. In this way, the locking and unlocking states can be realized through the first welded pipe 647 and the second welded pipe 648.

[0035] Specifically, the first welded pipe 647 and the second welded pipe 648 are symmetrically arranged on the left side of the push-pull shaft 645, and both the first welded pipe 647 and the second welded pipe 648 have external threads on their outer sides to ensure that the push-pull shaft 645 cooperates with the first welded pipe 647 and the second welded pipe 648 on the outer side to achieve a stable threaded connection with the middle left side of the positioning strip 641.

[0036] When the self-balancing device 6 needs to be disassembled, the push-pull shaft 645 located in the middle of the left side of the positioning bar 641 can be rotated to release the threaded fastening between the first welded pipe 647 on the left side of the push-pull shaft 645 and the positioning bar 641. This causes the compression spring 646, located outside the push-pull shaft 645 and in a compressed state, to rebound, thus automatically moving the right-side movable seat 642 to the left. As the movable seat 642 moves to the left, the upper and lower abutment bars 643 inside the movable seat 642 can move, releasing the locking effect on the support seat 631. Simultaneously, as the movable seat 642 moves to the left, the upper and lower abutment bars 643 can tilt through the hollow space inside the positioning bar 641. The oblique opening end cooperates to automatically retract the two side abutment bars 643, so that the two side abutment bars 643 automatically retract into the positioning bar 641, so as to avoid the two side abutment bars 643 obstructing the subsequent disassembly process of the support base 631. After the two side abutment bars 643 are retracted, the push-pull shaft 645 can be pulled to the left, so that the second welded pipe 648 provided on the outside of the push-pull shaft 645 abuts against the left side of the positioning bar 641. By rotating, the second welded pipe 648 and the positioning bar 641 are locked. In this way, the locking component 64 can be in a stable retracted state, so that the support base 631 can be smoothly moved out of the interior of the connecting seat 62 along the positioning bar 641, thereby realizing convenient disassembly and assembly and improving the ease of disassembly and assembly of the self-balancing device 6.

[0037] like Figure 5 As shown, the quick-connect assembly 66 in this embodiment includes a horizontal arm 661 that is laterally fastened to the upper end of the balance bar 65; a connecting shell 662 installed inside the right side of the horizontal arm 661 to protect the internal parts; pressure blocks 663 symmetrically arranged inside the right side of the horizontal arm 661, with both pressure blocks 663 slidingly embedded, and the outer surface of the right side of the pressure blocks 663 being smoothly inclined; a connecting bar 664 that is laterally fastened to the inner ends of the pressure blocks 663 and can be used for unlocking and transmission; and a plug rod 665 vertically inserted into the left side of the connecting bar 664, fastened to the outside of the plug rod 665 to achieve sliding combination and docking. The connecting plate 666 is used, the first spring 667 is installed on the outside of the plug rod 665 to achieve elastic push-back engagement, the first rack 668 is vertically arranged on the left end of the upper plug rod 665, and the lower front end of the first rack 668 is integrally provided with a connecting rod, so as to realize the convenient push engagement of the first rack 668, the gear 669 is meshed and connected to the middle of the first rack 668 and rotated and connected to the left side of the inside of the connecting shell 662, the second rack 6610 is meshed on the right side of the gear 669 and vertically fastened to the left end of the lower plug rod 665, and the extrusion structure 6a is arranged inside the right side of the cross arm 661 to improve the vertical flatness effect when connected with the steel grid frame 4.

[0038] To further explain, the extrusion structure 6a includes a receiving block 6a1 built into the inside of the right side of the cross arm 661, and the middle of the receiving block 6a1 is opened in a semi-arc groove to ensure stable docking and extrusion fit. The guide rods 6a2 are symmetrically inserted into the upper and lower ends of the receiving block 6a1 to achieve support and movement guidance fit. The second springs 6a3 are correspondingly set on the outside of the guide rods 6a2 on both sides to achieve elastic extrusion assistance.

[0039] To further explain, two sets of plug-in rods 665, connecting plates 666, and first springs 667 are symmetrically arranged on the left and right sides, and both sets of connecting plates 666 are plugged into the plug-in rods 665 to ensure that the two sets of plug-in rods 665, connecting plates 666, and first springs 667 can slide and connect together to form a guide frame, thereby ensuring the stability of the relative or opposite movement of the pressure blocks 663 on both sides.

[0040] When performing the self-balancing assembly of the steel space frame 4 and the balance bar 65, after completing the quick-connect movement of the support base 631 and the connecting base 62, one side of the assembled steel space frame 4 should be inserted into the inside of the right side of the cross arm 661. This causes the steel space frame 4 to press against the pressure blocks 663 at both ends of the inside of the right side of the cross arm 661. This causes the two pressure blocks to move in opposite directions, driving the connecting bars 664, which are fastened to their inner ends, to move in opposite directions synchronously. This process allows the two sets of interlocking rods 665, connecting plates 666, and first springs 667 to move and guide each other, stabilizing the opposite movement of the pressure blocks 663. Simultaneously, when the connecting plates 666 move in opposite directions, they compress the first springs 667 on the outside of the interlocking rods 665. Thus, when the steel space frame 4 passes between the two pressure blocks 663, the compressed first springs 667 on both sides rebound, achieving outward push transmission of the pressure blocks 663, thus stabilizing the opposite movement of the pressure blocks. When block 663 is connected to close the inlet, the steel grid frame 4 is stably positioned inside the right side of the cross arm 661. At the same time, during the insertion, it will connect with the extrusion structure 6a provided inside the right side of the cross arm 661, that is, it will abut against the semi-circular groove provided in the middle of the receiving block 6a1. During the insertion process, the receiving block 6a1 is pushed to the left, so that the receiving block 6a1 and the guide rods 6a2 inserted on both sides are moved to the left in advance, compressing the second springs 6a3 provided on the outside of the guide rods 6a2 on both sides. Thus, with the help of the rebound of the second springs 6a3 on both sides, the receiving block 6a1 can push the steel grid frame 4 to the right, which further enhances the connection stability of the steel grid frame 4. The steel grid frame 4 is positioned between the receiving block 6a1 and the closed pressure blocks 663 on both sides. In this way, the quick connection combination of the cross arm 661 and the steel grid frame 4 can be completed, so that the balance bar 65 can achieve self-balancing support for the entire steel grid frame 4, keeping it in a stable and vertical state and reducing the occurrence of installation tilt.

[0041] Secondly, when it is necessary to disengage the connection, the first rack 668 can be pushed to move it and drive the central meshing gear 669. Simultaneously, the second rack 6610, meshing with the gear 669 on the other side, will move. Thus, the first rack 668 and the second rack 6610 will move synchronously in opposite directions, correspondingly pushing the outer connecting strip 664. This causes the two connecting strips 664 to move in opposite directions, indirectly driving the outer pressure block 663, allowing the closed pressure blocks 663 to open quickly. This conveniently disengages the cross arm 661 from the steel space frame 4, achieving convenient self-balancing support for the steel space frame 4, ensuring stable connection at the beginning of the space frame, and preventing tilting.

[0042] This invention provides a self-balancing device for the starting of a space frame. By incorporating a self-balancing device 6, specifically a quick-connect component 66 at the upper end of the balance bar 65, the balance bar 65 can be quickly connected to one side of the steel space frame 4, enabling the steel space frame 4 to self-balance and ensuring its vertical installation. Furthermore, the support adjustment seat 63 connected to the lower end of the balance bar 65 allows for fine-tuning of the balance bar 65's overall tilt when the level bubble 67 on its exterior indicates tilt. This ensures the stability of the self-balancing connection of the balance bar 65. The locking component 64 inside the connecting seat 62 allows for convenient assembly and disassembly of the self-balancing device 6, facilitating quick assembly and disassembly of the steel space frame 4. This achieves the advantages of convenient self-balancing support for the steel space frame 4, ensuring stable connection at the start of the space frame and preventing tilting.
