Description

Technical Field

[0001] The present application relates to the technical field of gardening and greening, and in particular to a three-dimensional greening of bridge columns suitable for low maintenance in the north. Background Art

[0002] With the continuous advancement of urbanization, the increment of traditional ground greening is decreasing, and vertical greening is becoming an important part of urban greening construction. As an important form of urban vertical greening, vertical greening of viaduct columns has received more and more attention; bridge column greening is an important form of vertical greening and an effective way to increase the area of ​​urban green space; it can not only improve the urban ecological environment and landscape quality, but also provide urban residents with a better living environment and traffic experience.

[0003] At present, bridge column greening usually uses frame traction, container, bag and other auxiliary plants to climb the bridge column to achieve the effect of three-dimensional greening of the bridge column. However, these traditional three-dimensional greening methods are relatively close to the surface of the bridge column. When the plants grow, they will climb on the surface of the bridge column. The strong suction cups of the plants themselves may cause the coating on the surface of the column to peel off, affecting the appearance and quality and safety of the bridge column; at the same time, when the bridge body is maintained, the plants cover a large area on the surface of the bridge column, which increases the difficulty of bridge maintenance. The staff needs to remove the plants on the surface of the bridge column first, and then replant them after the bridge body maintenance is completed, which not only increases the workload, but also increases the maintenance cost. Summary of the invention

[0004] In order to reduce the maintenance cost of bridge bodies and bridge columns, the present application provides a three-dimensional greening of bridge columns suitable for low-maintenance in the north.

[0005] This application provides a three-dimensional greening solution for low-maintenance bridge columns in the north, which adopts the following technical solutions: A three-dimensional greening system for low-maintenance bridge columns in the north includes a supporting frame, the supporting frame comprises a plurality of columns and a plurality of cross bars, the plurality of columns are evenly arranged around the bridge column to form a rectangular frame, the bottom end of the column is fixedly connected to the ground, and the distance between the column and the surface of the bridge column is 0.75m; the plurality of cross bars are respectively fixedly connected between two adjacent columns, an oblique bar is fixedly connected between two adjacent cross bars, and a rectangular frame is formed between the mutually adjacent columns and cross bars, a net racket structure is detachably installed in the rectangular frame, connecting rods are fixedly connected around the net racket structure, a fixing component for fixing the net racket structure is arranged in the rectangular frame, and plants climb on the outer side of the net racket structure.

[0006] By adopting the above technical solution, the net racket structure on the rectangular frame can not only allow plants to climb, but also to a certain extent prevent plants from growing toward the bridge column. In addition, a spacing of 0.75m is set between the column and the bridge column, which can effectively keep plants away from the main surface of the bridge, prevent plants from climbing on the surface of the bridge column, and thus prevent plants from damaging the bridge column. The bridge columns of the overpass have a certain height. In the case of major repairs, it is necessary to use lifting machinery for overall repairs. Carrying out a large area of ​​the bridge work surface will cause large-scale damage to the greening of the bridge columns that have already grown. Restoring the greening requires repeated cost investment and a long time of recovery. Therefore, the detachable net racket structure can be partially disassembled in combination with the specific location of the bridge overhaul, thereby reducing the maintenance cost of the bridge column.

[0007] Preferably, a side wall of the support frame is provided with a hinged door.

[0008] By adopting the above technical solution, the hinged door makes it convenient for the staff to enter the support frame to observe and inspect the bridge columns on a daily basis. The distance between the support frame and the bridge column surface is 0.75m, which reserves enough space for the staff to move around and do local repair and maintenance work. The net racket structure and plants need to be dismantled, thereby reducing the workload and saving costs.

[0009] Preferably, the fixing assembly includes a plurality of fixing rods and a plurality of nuts, and the plurality of nuts and the plurality of fixing rods are threadedly matched one by one, and the plurality of fixing rods are respectively fixedly connected to the cross bar and the side wall of the column, and a fixing hole is opened on the connecting rod, and the fixing rod is inserted into the fixing hole and threadedly connected to the fixing rod with the nut, and the nut abuts against the connecting rod.

[0010] By adopting the above technical solution, when the corresponding position is blocked by vegetation according to the maintenance needs of the bridge column, the staff uses a tool to tighten the nut, and after removing the nut on the connecting rod, the staff can remove the connecting rod from the fixed rod, thereby removing the net racket structure from the rectangular frame, thereby facilitating the staff to maintain the bridge column, effectively avoiding the investment in repetitive plant costs, and saving costs.

[0011] Preferably, a drainage pipe is fixedly installed on the bridge column, a drainage energy dissipation pool is installed at the bottom of the bridge column, the drainage energy dissipation pool is arranged inside the supporting frame, the drainage energy dissipation pool is connected with the municipal drainage system, a manhole cover is installed on the drainage energy dissipation pool, and the bottom of the drainage pipe abuts against the manhole cover.

[0012] By adopting the above technical solution, the winter in the north is colder than other places, and the snowfall is also more. In order to ensure smooth travel for citizens, a certain amount of snow-melting agent needs to be sprinkled on the bridge surface. The dissolved water in the snow-melting agent will flow directly into the drainage energy dissipation pool through the drainage pipe, avoiding the melted snow water from flowing into the green space under the bridge. The snow-melting agent contains a large amount of salt chemicals, which seriously exceeds the tolerable range of plants and will cause plant death.

[0013] Preferably, a salt-intercepting drainage ditch is arranged on the ground around the bottom of the bridge column, the drainage energy dissipation pool is located at the lowest point of the salt-intercepting drainage ditch, and the salt-intercepting drainage ditch is composed of breathable expanded clay, PVC glass fiber anti-seepage membrane, composite geotextile, natural pebbles and PVC dividing strip.

[0014] By adopting the above technical solution, the salt interception drainage ditch can effectively separate the salt water from the planted green space, avoiding the splashing of sewage into the green space when the drainage pipe discharges water into the energy dissipation drainage pool, thereby ensuring the normal growth of plants.

[0015] Preferably, an intelligent sprinkler irrigation facility is installed on the ground on one side of the support frame away from the bridge column, and the intelligent sprinkler irrigation facility includes a ground irrigation nozzle, a water pipe and a telescopic pipe. The telescopic pipe is installed on the ground, the ground irrigation nozzle is connected to the telescopic pipe, and the water pipe is laid under the ground and connected to the telescopic pipe.

[0016] By adopting the above technical solutions, the intelligent sprinkler irrigation facilities can provide micro-spray irrigation to plants on a regular basis and in a fixed quantity as needed; it not only saves water, but also ensures the survival of plants, increases the humidity of the space under the bridge, effectively cools down in summer, and enhances the dust retention effect; at the same time, the telescopic pipe can be adjusted according to the height of the vegetation to avoid the sprayed water being blocked by the vegetation, thereby reducing the irrigation range.

[0017] Preferably, the fixing assembly includes a plurality of hooks and a plurality of first springs, the plurality of first springs and the plurality of hooks are arranged in one-to-one correspondence, a plurality of connecting holes are opened on the column and the cross bar, the plurality of first springs are respectively arranged in the plurality of connecting holes, the two ends of the first spring are respectively fixedly connected to the inner wall of the connecting hole and the hook, the hook is slidably connected to the inner wall of the connecting hole, and the end of the hook away from the first spring is hooked on the connecting rod.

[0018] By adopting the above technical solution, the staff can fix the racquet structure in the rectangular frame through the hook, simplifying its connection method and enabling quick disassembly and installation; the staff only needs to pull the hook to stretch the first spring to move outward to remove or hang the hook from the racquet structure, and the staff can retain the hook on one side of the racquet structure as needed. When the hooks on the other three sides are removed, the hook on the last side moves the connected hook into the connecting hole under the tension of the first spring, so that the hook mouth is pressed against the side wall of the cross bar or the side wall of the column. At this time, the staff can rotate the racquet structure, and the racquet structure is suspended on the supporting frame to avoid the racquet structure being completely disassembled and stacked together, making the racquet structure more flexible.

[0019] Preferably, the support frame includes a plurality of columns 2, a plurality of cross bars 2 and a plurality of connecting plates, the diameter of the columns 2 is smaller than that of the columns 1, the connecting plates are rotatably connected to the columns 2, the columns 2 are provided with connecting components connecting the connecting plates, and the columns 2 are provided with limiting components for limiting the rotation of the connecting plates; slots are provided at both ends of the cross bars 2, and the connecting plates and the slots are connected with mortise and tenon joints.

[0020] By adopting the above technical solution, the diameter of column two is smaller than that of column one, thereby improving the overall appearance of the support frame. When encountering major repairs on the bridge body and the bridge columns, the staff can release the connection assembly between the connecting plate on a certain side of the support frame and column two. At this time, the crossbar two, the racket structure and the connecting plate can be rotated as a whole to open the support frame, making it easier for the staff to carry out maintenance and other work. In daily work without maintenance, the limiting assembly limits the random rotation of the connecting plate, and fixing its position can improve the stability of the support frame.

[0021] Preferably, the connecting assembly includes a rotating rod and two sleeves, a rotating groove is provided on the second column, the rotating rod is fixedly connected to the connecting plate, and telescopic grooves are respectively provided at both ends of the connecting plate.

[0022] By adopting the above technical solution, when the staff installs the connecting plate, the staff first pulls the pull block to move the sleeves away from the socket. When the staff places the connecting plate in the rotating groove, the staff releases the pull block. When the staff adjusts the connecting plate in the rotating groove, the sleeve slides and connects to the inner wall of the rotating groove. When the sleeve and the socket are aligned, the sleeve is inserted into the socket under the action of the second spring. At this time, the connecting plate and the second column are installed. Similarly, when the staff needs to release the connection between the connecting plate and the second column, the staff pulls the pull block to compress the second spring to move the sleeve away from the socket. At this time, the staff takes the connecting plate out of the rotating groove.

[0024] By adopting the above technical solution, in daily life when no maintenance is required, the limiting block extends out of the placement slot and abuts against the side wall of the connecting plate under the action of the limiting spring to prevent the connecting plate from rotating; when the connecting plate needs to be rotated, the staff first drives the plug block away from the gear through the pull rod, and then the staff rotates the driving rod to retract the driving rope. The movement of the driving rope drives the limiting block to compress the limiting spring and move it into the placement slot. When the limiting block is completely in the placement slot, the staff can rotate the connecting plate to rotate the vegetation on the net racket structure to other positions, thereby facilitating the staff to carry out bridge column maintenance and other work.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The net racket structure on the rectangular frame not only allows plants to climb, but also blocks the plants from growing toward the bridge columns to a certain extent. In addition, a spacing of 0.75m is set between the columns and the bridge columns, which can effectively keep the plants away from the main surface of the bridge, prevent plants from climbing on the surface of the bridge columns, and thus prevent plants from damaging the bridge columns. The bridge columns of the overpass have a certain height. In the case of major repairs, it is necessary to use lifting machinery for overall repairs. Carrying out a large area of ​​the bridge work surface will cause large-scale damage to the greening of the bridge columns that have already grown. Restoring the greening requires repetitive cost investment and a long time of recovery. Therefore, the detachable net racket structure can be partially disassembled in combination with the specific location of the bridge overhaul, thereby reducing the maintenance cost of the bridge column; 2. The hinged door allows the staff to enter the support frame to observe and inspect the bridge columns on a daily basis. The distance between the support frame and the bridge column surface is 0.75m, which leaves enough space for the staff to move around and do local repair and maintenance work. The net racket structure and plants need to be dismantled, thereby reducing the workload and saving costs. 3. The diameter of column two is smaller than that of column one, which improves the overall appearance of the support frame. When the bridge body and bridge columns need to be overhauled, the staff can remove the connecting assembly between the connecting plate at one end of the side of the support frame and column two. At this time, the crossbar two, the racket structure and the connecting plate can be rotated as a whole to open the support frame, making it easier for the staff to carry out maintenance and other work. In daily work without maintenance, the limiting assembly limits the random rotation of the connecting plate, and fixing its position can improve the stability of the support frame.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-11 This application is described in further detail.

[0039] Embodiment 1 like Figure 1As shown, the first embodiment of the present application discloses a three-dimensional greening of bridge columns suitable for low maintenance in the north, including a support frame 1, the support frame 1 includes a plurality of columns 2 and a plurality of cross bars 3. In the first embodiment, the number of columns 2 is eight, and the eight columns are placed vertically and enclosed in a rectangle. Three columns 2 can be seen on each side, and the spacing between adjacent columns 2 is the same, and the bottom end of the column 2 is fixedly connected to the ground. The plurality of cross bars are all arranged horizontally, and the two ends of the cross bars are respectively fixedly welded between two adjacent columns, and an inclined rod 4 is fixedly welded between two adjacent cross bars 3, and the inclined rod 4 can increase the stability of the support frame 1. A rectangular frame 5 is formed between mutually adjacent columns 2 and cross bars 3, and a net rack structure 6 is detachably installed in the rectangular frame 5, and connecting rods 8 are fixedly connected around the net rack structure 6. A fixing component for fixing the net rack structure 6 is arranged in the rectangular frame 5, and plants climb on the outside of the net rack structure 6.

[0040] like Figure 1 and Figure 2 As shown, the distance between each column 1-2 and the bridge column surface is 0.75m, so that the support frame 1 is 0.75 meters away from the bridge column. A hinged door 9 is set at the bottom of one side of the support frame 1. The hinged door 9 can be opened, and the staff can enter the support frame 1 through the hinged door 9 to inspect and maintain the bridge column. The distance of 0.75m is enough space for the staff to perform construction and other operations. The fixing assembly assembly includes a plurality of fixing rods 11 and a plurality of nuts 10. The number of fixing rods 11 and nuts 10 in this embodiment 1 is selected to be eight, and the specific construction can be selected according to the needs. Two fixing rods 11 are placed at the four corners of the rectangular frame 5, respectively. The two fixing rods 11 are fixedly welded to the connected column 1-2 and the cross bar 1-3, respectively. The nuts 10 and the fixing rods 11 are threadedly matched one by one. The connecting rod 8 is provided with a plurality of fixing holes 12 for the fixing rods 11 to be inserted. The nuts 10 are threadedly connected to the fixing rods 11 and abut against the side walls of the connecting rod 8.

[0041] like Figure 1 and Figure 2As shown, the net structure 6 on the rectangular frame 5 can not only allow plants to climb, but also to a certain extent prevent the plants from growing toward the bridge column. In addition, a spacing of 0.75m is set between the columns and the bridge columns, which can effectively keep the plants away from the main surface of the bridge, prevent the plants from climbing on the surface of the bridge columns, and thus prevent the plants from damaging the bridge columns. The hinged door 9 is convenient for the staff to enter the support frame 1 to observe and inspect the bridge columns on a daily basis. At the same time, the distance of 0.75m between the support frame 1 and the surface of the bridge columns reserves enough space for the staff to move around and repair the bridge columns. The bridge columns of the overpass are all of a certain height. In the event of major repairs, it is necessary to use lifting machinery for overall maintenance and to carry out a larger area of ​​the bridge work surface, which will cause large-scale damage to the greening of the bridge columns that have already grown. At this time, the staff uses a tool to tighten the nut 10, and after removing the nut 10 on the connecting rod 8, the staff can remove the connecting rod 8 from the fixed rod 11, thereby removing the net racket structure 6 from the rectangular frame 5, which can avoid damage to the vegetation on the net racket structure 6. When the maintenance is completed, the staff will install the net racket structure 6, thereby saving the repetitive cost investment required to restore the greening and the longer recovery time.

[0042] like Figure 1 and Figure 3 As shown, a drainage pipe 13 is fixedly installed on the bridge column, and a drainage energy dissipation pool 14 is arranged at the bottom of the bridge column. The drainage energy dissipation pool 14 is connected to the municipal drainage system. A manhole cover 15 is installed on the drainage energy dissipation pool 14, and the bottom of the drainage pipe 13 abuts against the manhole cover 15. In winter, a certain amount of snow melting agent is sprinkled on the bridge pavement. The water dissolved by the snow melting agent will flow directly into the drainage energy dissipation pool 14 along the drainage pipe 13 to prevent the melted snow water from flowing into the green space under the bridge and causing the death of plants. A salt interception drainage ditch 16 is arranged on the ground around the bottom of the bridge column. The salt interception drainage ditch 16 is composed of breathable ceramsite 17, PVC glass fiber anti-seepage coil 18, composite geotextile 19, natural pebbles 20 and PVC dividing strip 21 from the bottom to the top layer; and the salt interception drainage ditch 16 is higher around, and the drainage energy dissipation pool 14 is the lowest, so that the sewage can flow into the energy dissipation pool. When the drainage pipe 13 drains water, the salt interception drainage ditch 16 can effectively separate the salt water from the planted green land, avoiding the sewage from splashing into the green land when the drainage pipe 13 drains water to the energy dissipation drainage pool, thereby ensuring the normal growth of plants.

[0043] like Figure 1As shown, an intelligent sprinkler irrigation facility 22 is installed on the ground on one side of the support frame 1 away from the bridge column. The intelligent sprinkler irrigation facility 22 includes a ground irrigation nozzle 23, a water pipe and a telescopic pipe 24. The telescopic pipe 24 is installed on the ground, and the ground irrigation nozzle 23 is installed on the top of the telescopic pipe 24. The water pipe is laid under the ground and connected to the telescopic pipe 24. The intelligent sprinkler irrigation facility 22 can perform micro-spray irrigation on plants on a regular and quantitative basis as needed; at the same time, the telescopic pipe 24 can adjust the height according to the height of the vegetation to avoid the sprayed water being blocked by the vegetation, expand the irrigation range, not only save water, but also ensure the survival of plants, increase the humidity of the space under the bridge, effectively cool down in summer, and have the effect of cleaning and removing dust from the leaves of vegetation.

[0044] The implementation principle of the first embodiment of the present application is as follows: the net rack structure 6 on the rectangular frame 5 can not only provide climbing for plants, but also prevent the plants from growing toward the bridge column to a certain extent; in addition, a spacing of 0.75m is set between the upright column and the bridge column, which can effectively keep the plants away from the main surface of the bridge, prevent the plants from climbing on the surface of the bridge column, and thus prevent the plants from damaging the bridge column. At the same time, a hinged door 9 is provided at the bottom of one side of the support frame 1, which is convenient for the staff to enter the inner wall of the support frame 1, so that the staff can perform maintenance and repair work on the bridge column without removing the plants. The bridge columns of the overpass bridge body have a certain height. In the case of overhaul, it is necessary to use hoisting machinery for overall maintenance, and to carry out a large area of ​​bridge body working surface, which will cause large-scale damage to the greening of the bridge column that has grown well; when restoring the greening, it requires repeated cost investment and a long time of recovery. Therefore, the staff only needs to release the fixed components to disassemble the net rack structure 6, and can carry out partial disassembly in combination with the specific location of the bridge body overhaul, thereby reducing the maintenance cost of the bridge body and bridge column.

[0045] Implementation II like Figure 4 As shown, the difference between the second embodiment and the first embodiment is that the fixing assembly includes a plurality of hooks 25 and a plurality of first springs 26. The number of the hooks 25 and the first springs 26 in the second embodiment are both eight. The plurality of first springs 26 and the plurality of hooks 25 are arranged one by one. Two connecting holes 27 are provided on the upright column and the crossbar in the rectangular frame 5. The plurality of first springs 26 are respectively arranged in the plurality of connecting holes 27. The two ends of the first spring 26 are respectively fixedly welded to the inner wall of the connecting hole 27 and the hook 25. The hook 25 is slidably connected to the inner wall of the connecting hole 27. The end of the hook 25 away from the first spring 26 is hooked on the connecting rod 8. A blocking block 28 is slidably provided in the connecting hole 27. The blocking block 28 abuts against the inner wall of the connecting hole 27. The blocking block 28 is fixedly sleeved on the hook 25, thereby reducing the possibility of the hook 25 being separated from the connecting hole 27.

[0046] The implementation principle of the second embodiment of the present application is as follows: the staff fixes the racket structure 6 in the rectangular frame 5 through the hook 25, simplifies the connection method, and can be quickly disassembled and installed; the staff only needs to pull the hook 25 to stretch the first spring 26 to move outward, and remove or hang the hook 25 from the racket structure 6. In addition, the staff can retain the hook 25 on one side of the racket structure 6 as needed. When the hooks 25 on the other three sides are removed, the hook 25 on the last side moves the hook 25 connected to it into the connection hole 27 under the tension of the first spring 26, so that the hook 25 is tightly pressed against the side wall of the crossbar 3 or the side wall of the column 2. At this time, the staff can rotate the racket structure 6, and the racket structure 6 is suspended on the support frame 1 to avoid the racket structure 6 being completely disassembled and piled up, and the racket structure 6 is more flexible.

[0047] Implementation Three like Figure 5 and Figure 6 As shown, the difference between this embodiment 3 and embodiment 2 is that: the support frame 1 includes multiple columns 29, multiple crossbars 20 and multiple connecting plates 31. The columns 29 are cylindrical and vertically arranged. The number of columns 29 is selected to be four, and eight columns can also be set in accordance with embodiment 1. In this embodiment, four columns 29 are used as an example. The four columns are respectively arranged at the four corners of the bridge column and fixedly connected to the ground. The diameter of the column 29 is smaller than the column 1 2, which makes it easier to hide in the vegetation, thereby improving the aesthetics. The connecting plate 31 is in the shape of a rectangular parallelepiped. Two connecting plates 31 are rotatably connected on each column 29. A connecting component 32 connecting the connecting plates 31 is provided on the column 29, and a limiting component 33 for limiting the rotation of the connecting plates 31 is provided on the column 29.

[0048] like Figure 6 and Figure 7 As shown, combined with Figure 8As shown, the cross sections of both ends of the second crossbar 30 are provided with slots 34 along the diameter direction thereof, and the side walls of the connecting plate 31 are connected with the slots 34 by mortise and tenon joints, which not only facilitates transportation but also improves the fixing effect. The connecting assembly 32 includes a rotating rod 35 and two sleeves 36, and the side walls of the second column 29 are provided with a rotating groove 37 along the vertical direction, and the connecting plate 31 can be rotated 180 degrees in the rotating groove 37, so that one side wall of the supporting frame can be completely opened inward or outward. One end of the connecting plate 31 close to the second column 29 is fixedly sleeved on the rotating rod 35, and the upper and lower ends of the connecting plate 31 are respectively provided with telescopic grooves 38 in the vertical direction. The two sleeves 36 slide in the two telescopic grooves 38 in the vertical direction respectively. The sleeve 36 is sleeved on the rotating rod 35 in the vertical direction. The inner wall of the sleeve 36 is provided with a limiting groove 54 along its length direction. A limiting block 54 is fixedly welded on the side wall of the rotating rod 35, and the limiting block 55 is slidably connected to the inner wall of the limiting groove 54. Under the limitation of the limiting block 55, when the connecting plate 31 and the rotating rod 35 move, the sleeve 36 can be driven to rotate together. The upper and lower inner walls of the rotating groove 37 are provided with a socket 39 for inserting the sleeve 36 in the vertical direction. A slide groove 42 is respectively provided at the upper and lower ends of the side wall of the connecting plate 31, a pull block 40 slides in the slide groove 42, the pull block 40 is fixedly welded to the side wall of the sleeve 36, a second spring 41 is arranged in the slide groove 42, and the two ends of the second spring 41 are respectively fixedly welded to the inner wall of the slide groove 42 and the pull block 40.

[0049] like Figure 5 and Figure 7 As shown, when the bridge body and bridge column are overhauled, the staff can release the connection assembly 32 between the connecting plate 31 at one end of one side of the support frame 1 and the second column 29 as needed. First, the staff pulls the upper pull block 40 downward and the lower pull block 40 upward. The movement of the pull block 40 drives the sleeve 36 to move away from the socket 39. When the sleeve 36 is completely out of the socket 39, the staff can offset the connecting plate 31 to make the sleeve 36 and the socket 39 staggered. At this time, the staff can release the pull block 40 and pull the connecting plate 31 out of the rotating groove 37. After the limiting assembly 33 is released, the other connecting plate 31 on the same side as the connecting plate 31, at this time, the crossbar 2 30, the racket structure 6 and the connecting plate 31 on this side can rotate as a whole. The staff rotates the connecting plate 31 and opens the support frame 1, which is convenient for the staff to carry out maintenance and other work. When the staff installs the connecting plate 31, the staff first pulls the pull block 40 to move the sleeve 36 to the middle of the connecting plate 31. When the staff places the connecting plate 31 in the rotating groove 37, the staff releases the pull block 40. When the staff adjusts the connecting plate 31 in the rotating groove 37, the sleeve 36 slides and connects to the inner wall of the rotating groove 37. When the sleeve 36 and the socket 39 are aligned, the sleeve 36 is inserted into the socket 39 under the action of the second spring 41. At this time, the connecting plate 31 and the second column 29 are installed.

[0050] like Fig. 9 and Fig.10 As shown, the limiting assembly 33 includes two limiting blocks 43, two limiting springs 44 and a driving rope 45. A placement groove 46 is provided on the side wall of the second column 29. The placement groove 46 extends to the upper and lower ends thereof, and the placement groove 46 is C-shaped. The two limiting blocks 43 slide at the top and bottom ends of the placement groove 46 in the vertical direction respectively. The two limiting blocks 43 abut against the top side wall and the bottom side wall of the connecting plate 31 respectively, and are connected to the two limiting blocks 43 respectively. The two ends of the limiting spring 44 are fixedly welded to the limiting blocks 43 and the inner wall of the placement groove 46 respectively. The limiting blocks 43 are provided with inclined surfaces 47, and the inclined surfaces 47 of the two limiting blocks 43 are arranged opposite to each other. A driving rod 48 is provided on the inner wall of the placement groove 46, and the driving rope 45 is wound around the driving rod 48. A plurality of fixed pulleys 49 are installed in the placement groove 46, and the fixed pulleys 49 can change the direction of the driving rope 45.

[0051] like Fig. 9 and Fig.10 As shown, combined with Fig.11 As shown, the driving rod 48 is located on the side wall of the second column 29, and a gear 50 is fixedly sleeved on the driving rod 48. A storage groove 51 is opened on the inner wall of the placement groove 46, and an insert block 52 is slidably connected to the inner wall of the storage groove 51. A third spring 56 is vertically arranged in the storage groove 51, and both ends of the third spring 56 are fixedly welded to the inner wall of the storage groove 51 and the insert block 52 respectively. The insert block 52 is located above the gear 50. The insert block 52 is inserted into the tooth groove of the gear 50 under the action of its own gravity and the elastic force of the third spring 56, thereby limiting the rotation of the gear 50 and the drive. A pull rod 53 is fixedly welded on the plug block 52. The staff can drive the plug block 52 away from the gear 50 by pulling the pull rod 53. At this time, the staff can shrink the drive rope 45 by rotating the drive rod 48, so as to compress the limit block 43 into the placement slot 46 to move the limit spring 44. When the limit block 43 is completely moved into the placement slot 46, the staff fixes the drive rod 48 through the plug block 52. At this time, the staff can rotate the connecting rod 8. In daily life without maintenance, the limit block 43 extends out of the placement slot 46 under the action of the limit spring 44 and abuts against the side wall of the connecting plate 31, preventing the connecting plate 31 from rotating, fixing its position, improving the stability of the support frame 1, and improving the wind resistance of the support frame.

[0052] The implementation principle of the third embodiment of the present application is: the diameter of the second column 29 is smaller than that of the first column 2, which improves the overall appearance of the support frame 1. When the bridge body and bridge columns are overhauled, the staff can remove the connecting plate 31 at one end of one side of the support frame 1 and the connecting component 32 between the second column 29. At this time, the second cross bar 30, the racket structure 6 and the connecting plate 31 can be rotated as a whole, thereby opening one side of the support frame 1, which is convenient for the staff to carry out maintenance and other work; in daily life without maintenance, the limiting component 33 limits the random rotation of the connecting plate 31, and fixing its position can improve the stability of the support frame 1.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
