Description

Technical Field

[0001] This application relates to the technical field of large-span supports, and in particular to an inclined support assembly with a universal joint at the middle column. Background Art

[0002] A large-span support is a support system used to support and carry structures with a large span. It is suitable for adapting to large-span spaces, providing strong support force, and ensuring the stability of the structure.

[0003] At present, the fixing of steel strands on the middle column of large-span supports is designed using the eccentric principle. This design makes the rotation center of the steel strand located below the rotation center of the middle column. When rotating simultaneously, the steel strand is compressed and needs to be consistent with the movement trajectory of the middle column, and the steel strand needs to contract. At this time, if the lateral load is too large, the contracted steel strand cannot provide lateral tension to the middle column. At this time, the load force on the rotating hinge of the middle column is too large and is prone to bending, and at the same time, the overall structure will also swing left and right, which is not conducive to the structural stability. This form requires a large strength for the hinge joint, and at the same time, the cost is too high, which is not conducive to large-scale production. Utility Model Content

[0004] The embodiment of this application provides an inclined support assembly with a universal joint at the middle column, which uses a universal joint and an inclined support assembly to replace the fixing of the steel strand, and adopts a concentric structure. The rotation point of the middle column, the universal joint, and the inclined support assembly are on the same horizontal line. In this way, it is neither pulled nor pressed during the rotation process, making their movement trajectories consistent and ensuring the structural stability. When the middle column is subjected to a lateral load, the inclined support assembly provides lateral support force for the middle column, enabling the support structure to also maintain stability, avoiding problems such as bending due to excessive load, and unstable structure swaying left and right. It solves the problem that when the middle column rotates, the steel strand contracts during synchronous movement and cannot provide lateral tension to the middle column. At this time, if the lateral load on the middle column is too large, the load force on the rotating hinge of the middle column is too large and is prone to bending, and at the same time, the overall structure will also swing left and right, which is not conducive to the structural stability.

Detailed implementation manners

[0036] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0037] The large-span solar bracket is a bracket structure specifically used for installing solar panels and has the characteristic of a large span. Its main advantages include:

[0038] 1. Improve land utilization rate: More solar panels can be installed on the same land area, especially suitable for areas with limited land resources.

[0039] 2. Enhance system stability: Through reasonable design and structural optimization, it can ensure the stability of the bracket and solar panels under large-span conditions and resist the influence of natural forces such as wind and snow.

[0040] 3. Reduce costs: Reduce the number of brackets and the number of foundation constructions, thereby reducing material and construction costs to a certain extent.

[0041] 4. Easy to maintain: The relatively open layout facilitates the daily maintenance and cleaning of the solar panels.

[0042] In projects such as large-scale solar power stations and solar agricultural greenhouses, the large-span solar brackets have been increasingly widely used.

[0043] Currently, the fixing of the steel wire ropes on the columns in the large-span brackets is designed based on the eccentric principle. This design makes the rotation center of the steel wire rope located below the rotation center of the middle column. When rotating simultaneously, the steel wire rope is under pressure and needs to be consistent with the movement trajectory of the middle column, and the steel wire rope needs to contract. At this time, if the lateral load is too large, the contracted steel wire rope cannot provide lateral tension for the middle column. At this time, the hinge joint of the middle column is subjected to too much load and is prone to bending, and at the same time, the overall structure will also swing left and right, which is not conducive to the structural stability. This form requires a relatively high strength for the hinge joints, and at the same time, the cost is too high, which is not conducive to large-scale production.

[0044] The middle-column universal joint type inclined support assembly provided by this application uses a universal joint and an inclined support assembly to replace the fixing of the steel wire rope, making the entire structure more stable in force. At the same time, this structure is easy to process and can also save costs. Moreover, with a concentric structure, the rotation point of the middle column, the universal joint, and the inclined support assembly are on the same horizontal line. In this way, it is neither in tension nor in compression during the rotation process, making its movement trajectory consistent and ensuring the structural stability. When the middle column is subjected to a lateral load, the inclined support assembly provides lateral support force for the middle column, enabling the bracket structure to also maintain stability and avoiding problems such as bending due to excessive load and unstable structure swaying left and right.

[0045] The following will describe in detail the specific structure of the middle-column universal joint type inclined support assembly provided by this application with reference to the accompanying drawings.

[0046] Refer to Figures 1-7 As shown, the embodiment of this application provides a middle-column universal joint type inclined support assembly, including a middle column 1, a universal joint 3, and an inclined support assembly 5;

[0047] The middle column 1 is a column with a certain strength. Two middle columns 1 are arranged side by side. Bases 2 are provided at the lower parts of the two middle columns 1. A rotating shaft 28 is provided on the base 2, and the middle column 1 is connected to the rotating shaft 28. As Figure 1 and Figure 2 shown, the rotating shaft 28 is arranged horizontally, enabling the middle column 1 to swing back and forth relative to the base 2;

[0048] The universal joint base 3 is of a cylindrical structure. The universal joint base 3 is rotatably connected to the base 2. The universal joint base 3 includes a cylinder body 31. The central axis of the cylinder body 31 is perpendicular to the central axis of the rotating shaft 28. A through groove 33 and a second pin hole 34 are provided on the cylinder body 31 and are communicated with each other. The through groove 33 can be a direction slot hole, and the second pin hole 34 is a round hole. The extending direction of the through groove 33, the central axis of the second pin hole 34, and the central axis of the cylinder body 31 are perpendicular to each other. The center of the second pin hole 34 is located on the central axis of the rotating shaft 28;

[0049] The inclined support assembly 5 is arranged between the two middle columns 1. The left end of the inclined support assembly 5 is connected to the universal joint base 3 on the left side, and the right end of the inclined support assembly 5 is rigidly connected to the middle column 1 on the right side. The inclined support assembly 5 includes a lower inclined rod 51 and an upper inclined rod 52;

[0050] The lower inclined rod 51 includes an outer tube body 53 and a connecting member 54. The connecting member 54 can be a connecting plate. The connecting member 54 is arranged at the left end of the outer tube body 53. A connecting hole 55 is provided on the connecting member 54. The connecting member 54 is inserted into the through groove 33. The second pin 6 is inserted into the second pin hole 34 and the connecting hole 55, so that the inclined support assembly 5 can swing up and down around the central axis of the cylinder body 31, and the inclined support assembly 5 can swing back and forth around the central axis of the second pin 6. A waist-shaped hole 56 is provided on the outer tube body 53. The waist-shaped hole 56 can be a 1 / 4 arc;

[0051] The upper inclined rod 52 includes an inner tube body 57. A round hole 58 is provided on the inner tube body 57. The first end of the inner tube body 57 is inserted into the second end of the outer tube body 53. The third pin 7 passes through the waist-shaped hole 56 and is inserted into the round hole 58. The inner tube body 57 is rotatably connected to the outer tube body 53. The third pin 7 is slidably connected to the waist-shaped hole 56.

[0052] The universal joint base 3, the second pin 6, and the inclined support assembly 5 form a support assembly. When the middle column 1 swings back and forth, the support assembly moves synchronously. For example, when the middle column 1 swings backward, the upper end of the support assembly moves backward and downward at the same time and rotates itself, that is, the inclined support assembly 5 swings backward around the central axis of the second pin 6, and the inclined support assembly 5 and the second pin 6 swing downward around the central axis of the cylinder body 31. The inner tube body 57 rotates clockwise relative to the outer tube body 53, thereby realizing three-dimensional movement;

[0053] Because the middle column 1 rotates around the central axis of the rotating shaft 28, the central axis of the cylinder body 31 is perpendicular to the central axis of the rotating shaft 28, the extending direction of the through groove 33, the central axis of the second pin hole 34, and the central axis of the cylinder body 31 are perpendicular to each other, and the center of the second pin hole 34 is located on the central axis of the rotating shaft 28. Therefore, during the forward and backward swing of the middle column 1, the support assembly is neither compressed nor stretched, and the length remains unchanged.

[0054] The central axis for the up-and-down rotation of the support assembly, i.e., the central axis of the universal joint 3, intersects with the central axis for the front-and-back rotation of the support assembly, i.e., the central axis of the second pin shaft 6, at a point, and this point is located on the central axis of the rotating shaft 28. When the middle column 1 rotates back and forth around the central axis of the rotating shaft 28, the support assembly rotates synchronously around the central axis of the rotating shaft 28. The areas swept by the middle column 1 and the support assembly form a conical body of 1 / N. The support assembly is the generatrix of the conical body. Therefore, during the forward and backward swinging of the middle column 1, the support assembly is neither compressed nor stretched, and its length remains unchanged;

[0055] During the forward and backward swinging of the middle column 1, the inner tube body 57 rotates relative to the outer tube body 53, and the third pin shaft 7 slides in the waist-shaped hole 56. When the inner tube body 57 rotates by a certain angle, the third pin shaft 7 engages with the end of the waist-shaped hole 56, preventing the inner tube body 57 from continuing to rotate, and thus preventing the support assembly from rotating forward or backward with the middle column 1, thereby restricting the forward and backward rotation of the middle column 1, that is, the forward and backward rotation of the middle column 1 is restricted by the design dimensions of the waist-shaped hole 56 and the third pin shaft 7.

[0056] Refer to Figure 6 As shown, in some embodiments, there are multiple round holes 58, and the multiple round holes 58 are evenly distributed along the extension direction of the inner tube body 57, so as to facilitate the adjustment of the total length of the inclined support assembly 5 and prevent problems such as the inclined support assembly 5 being too long or too short to be assembled or difficult to assemble during the assembly process.

[0057] Refer to Figure 1 As shown, in some embodiments, the middle column universal joint type inclined support assembly further includes a fixing rod 8. The fixing rod 8 can be a metal rod body, and the fixing rod 8 is arranged between the two middle columns 1;

[0058] Connecting plates are provided on the outer walls of the two middle columns 1. The connecting plates can be rectangular plate bodies. The two ends of the fixing rod 8 are rigidly connected to the connecting plates on the two middle columns 1 respectively. When the inclined support assembly 5 rotates, the fixing rod 8 drives the two middle columns 1 on both sides to rotate synchronously, always maintaining the stability of the structure.

[0059] Refer to Figure 6 As shown, in some embodiments, the upper inclined rod 52 further includes a U-shaped buckle 59. The U-shaped buckle 59 is fixedly arranged at the second end of the inner tube body 57. The U-shaped buckle 59 is a conventional U-shaped connecting piece, and the U-shaped buckle 59 is rigidly connected to the connecting plate on the middle column 1 through a bolt.

[0060] Refer to Figures 2-5 As shown, in some embodiments, a through hole 32 is axially provided in the column body 31, and the through hole 32 can be a round hole;

[0061] The base 2 is provided with two opposite side plates 21. The side plates 21 can be vertically arranged metal plates. Opposite first pin holes 22 are provided on the two side plates 21. First pins 4 are provided on both of the two side plates 21. The two first pins 4 respectively penetrate through the two first pin holes 22 and are respectively inserted into both ends of the through hole 32, so that the universal joint 3 rotates around the first pin 4.

[0062] In some embodiments, a ring body 23 coaxial with the first pin hole 22 is provided on the side plate 21. The ring body 23 can be a metal ring. A jack 24 is provided on the ring body 23. The jack 24 penetrates through both ends of the ring body 23;

[0063] A fixing hole 41 is provided on the first pin 4. The fixing hole 41 can be a vertical round hole. A split pin 9 penetrates through the jack 24 and the fixing hole 41 to fix the first pin 4 on the side plate 21.

[0064] Referring to Figure 2 As shown, in some embodiments, the base 2 includes a bottom plate 25. Opposite first plate bodies 26 and second plate bodies 27 are provided on the bottom plate 25. The first plate bodies 26 and the second plate bodies 27 are both vertically arranged metal plates. The extending directions of the first plate bodies 26 and the second plate bodies 27 are the same as the extending direction of the first pin hole 22;

[0065] Shaft holes for connecting a rotating shaft 28 are provided on both the first plate body 26 and the second plate body 27. The rotating shaft 28 is inserted into the two shaft holes, and the rotating shaft 28 is rotatably connected to the first plate body 26 and the second plate body 27. Both of the two side plates 21 are arranged on the outer wall of the second plate body 27.

[0066] In some embodiments, the base 2 further includes a reinforcing plate 29;

[0067] The reinforcing plate 29 can be a metal plate. The reinforcing plate 29 is fixedly arranged on the outer wall of the first plate body 26. The reinforcing plate 29 is vertically arranged. The reinforcing plate 29 is connected to the bottom plate 25 to improve the stability of the base 2.

[0068] As recorded by the above technical features, the working principle of the middle column universal joint type inclined support assembly provided by the present application in the actual application scenario is:

[0069] The universal joint 3, the second pin shaft 6, and the inclined support assembly 5 constitute a support assembly. When the middle column 1 swings back and forth, the support assembly moves synchronously. The inclined support assembly 5 swings back and forth around the central axis of the second pin shaft 6. The inclined support assembly 5 and the second pin shaft 6 swing up and down around the central axis of the column body 31. The inner tube body 57 rotates relative to the outer tube body 53 to achieve three-dimensional movement. And because the middle column 1 rotates around the central axis of the rotating shaft 28, the central axis of the column body 31 is perpendicular to the central axis of the rotating shaft 28. The extending direction of the through groove 33, the central axis of the second pin shaft hole 34, and the central axis of the column body 31 are perpendicular to each other. The center of the second pin shaft hole 34 is located on the central axis of the rotating shaft 28. Therefore, during the forward and backward swing of the middle column 1, the support assembly is neither compressed nor stretched, and the length remains unchanged.

[0070] When the middle column 1 is subjected to a lateral load, the support assembly can provide a supporting force for the middle column 1 to keep the middle column 1 stable and avoid problems such as bending due to excessive load and unstable structure with left and right swaying.

[0071] The universal joint type inclined support rod-shaped structure provided by the present application uses a universal joint and an inclined support assembly to replace the steel strand fixation, making the entire structure more stable in force. At the same time, this structure is easy to process and can save costs. And, adopting a concentric structure, the rotation point of the middle column, the universal joint, and the inclined support assembly are on the same horizontal line. In this way, it is neither stretched nor compressed during the rotation process, making its movement trajectory consistent and ensuring the structural stability. When the middle column is subjected to a lateral load, the inclined support assembly provides a lateral supporting force for the middle column, making the support structure also stable and avoiding problems such as bending due to excessive load and unstable structure with left and right swaying.

[0072] It is easy to understand that those skilled in the art can combine, split, recombine, etc. the embodiments of the present application based on several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.
