Description

Technical Field

[0001] This utility model relates to the field of corrugated culvert technology, specifically to a corrugated culvert anti-deformation structure. Background Technology

[0002] Corrugated culverts, as a type of culvert structure that combines high strength, lightweight and convenient construction, have been widely used in highways, railways, municipal engineering and water conservancy facilities. Especially in complex geological conditions such as soft soil foundations and mountainous terrain, they have gradually replaced traditional reinforced concrete culverts due to their good flexibility and ability to adapt to foundation deformation.

[0003] However, in practical engineering applications, geological conditions such as uneven settlement of soft soil foundations, foundation displacement caused by seismic activity, and volume changes of expansive or collapsible soils can easily lead to radial compression or local torsional deformation of culverts. On the other hand, the long-term effects of external loads (such as heavy vehicle loads, backfill pressure, flood impact, etc.) may cause stress concentration at the crests and troughs of the corrugated structure of the culvert, which in turn causes deformation of the corrugated culvert and affects its performance. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a corrugated culvert anti-deformation structure to solve the technical problem that corrugated culverts are prone to deformation under external force in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a corrugated culvert anti-deformation structure, including a culvert body, a support block, an mounting block, and an installation mechanism. The culvert body has arc-shaped support blocks on both sides. Each support block has a support groove at both ends of its inner wall. A first installation opening is provided at the bottom of the support groove. Mounting blocks are provided on both sides between two support blocks, wherein the mounting blocks extend into the support grooves. The installation mechanism is disposed between the mounting blocks and the support blocks for installing and fixing the support blocks and the mounting blocks.

[0006] Preferably, the installation mechanism includes a second installation port, an installation post, a first housing, and a positioning mechanism. The culvert body has a second installation port on one side of the first installation port, and the first installation port is aligned with the adjacent second installation port. Two installation posts are fixedly installed on the installation block. The installation posts extend out of the culvert body through the first installation port and the second installation port. The first housing is disposed on two opposite side walls of the culvert body. The first housing has a first positioning port, wherein the installation post extends through the first positioning port. The positioning mechanism is disposed between the first housing and the installation post for positioning the first housing and the installation post.

[0007] Furthermore, the positioning mechanism includes a positioning block, a second positioning port, a limiting mechanism, and a moving mechanism. The positioning block is slidably disposed within the first housing. The second positioning port is provided on one side of the positioning block located at the first positioning port. The mounting post passes through the first positioning port and the second positioning port. The limiting mechanism is disposed between the positioning block and the mounting post to limit the distance between the side wall of the second positioning port and the mounting post. The moving mechanism is disposed between the first housing and the positioning block to adjust the position of the positioning block.

[0008] Furthermore, the limiting mechanism includes a limiting port, a limiting groove, a limiting block, a first threaded rod, and a synchronous rotation mechanism. The limiting port is opened on the mounting post, and the limiting groove is opened on the side wall of the second positioning port. The limiting block is slidably disposed in the limiting groove, and one end of the limiting block away from the limiting groove extends into the limiting port. The first threaded rod is rotatably disposed at the bottom of the limiting groove and extends into the limiting block through threaded engagement. The synchronous rotation mechanism is disposed on the positioning block and is used to drive the two first threaded rods to rotate synchronously.

[0009] Furthermore, the synchronous rotation mechanism includes a first cavity, a second bevel gear, and a drive mechanism. The first cavity is formed within the positioning block. A first bevel gear is rotatably mounted on the side wall of the first cavity near the first threaded rod. The first bevel gear is fixedly connected to the adjacent first threaded rod. A second bevel gear is rotatably mounted on the side wall of the first cavity and meshes with the first bevel gear. The drive mechanism is mounted on the positioning block and is used to drive the second bevel gear to rotate.

[0010] Based on the above scheme, the driving mechanism includes a first driving port, a second driving port, a driving prism, and a first handwheel. The first driving port is opened on the side wall of the first cavity, the second driving port is opened on the second bevel gear, the driving prism is rotatably disposed in the first housing, the driving prism passes through the first driving port and the second driving port, the driving prism is slidably connected to the side wall of the second driving port, and the first handwheel is rotatably disposed on the first housing and is fixedly connected to the driving prism.

[0011] Based on the above scheme, the moving mechanism includes a second threaded rod and a second handwheel. The second threaded rod is rotatably disposed in the first housing and passes through the positioning block through a threaded engagement. The second handwheel is rotatably disposed on the first housing and is fixedly connected to the second threaded rod.

[0012] Based on the above scheme, a sealing ring is fixedly provided at one end of the mounting column near the mounting block, and the sealing ring contacts the side wall of the support groove.

[0013] The beneficial effects of the embodiments of this utility model are as follows:

[0014] 1. In this utility model, by setting up an installation mechanism, after the installation block extends into the support through groove and the installation column passes through the first installation port and the second installation port, the installation and fixation between the installation column and the first housing can be achieved by the operation of the positioning mechanism. Thus, the installation block and the support block can be positioned by the cooperation of the installation column with the first installation port and the second installation port respectively. At the same time, the culvert body can be positioned with the installation block and the first housing by the cooperation of the installation column with the installation block and the first housing respectively. This facilitates the support of the culvert body by the support block, thereby preventing the culvert body from deforming under the action of external force.

[0015] 2. In this utility model, by setting a limiting mechanism, the rotation of the first handwheel can drive the drive prism to rotate, and at the same time, the sliding engagement of the second drive port of the drive prism drives the second bevel gear to rotate. Then, the meshing of the second bevel gear and the first bevel gear can drive the first threaded rod to rotate. Thus, the threaded engagement of the first threaded rod with the limiting block can drive the limiting block to move and drive one end of the limiting block to extend into the limiting port. This facilitates the limiting of the positioning block and the mounting column by the engagement of the limiting block with the limiting groove and the limiting port respectively.

[0016] 3. In this utility model, by setting up a moving mechanism, after the positioning block and the mounting column are limited, the second threaded rod can be rotated by rotating the second handwheel. At the same time, the positioning block can be moved by the threaded engagement between the second threaded rod and the positioning block. This allows the distance between the first housing and the mounting base to be adjusted, thereby driving the first housing to press against the culvert body while driving the mounting block to press against the side wall of the support channel, which facilitates the improvement of the installation stability of the mounting block and the support block.

[0030] like Figures 1-5 As shown, a corrugated culvert anti-deformation structure according to an embodiment of the present invention is illustrated, including a culvert body 1, a support block 2, an mounting block 5, and an installation mechanism. Arc-shaped support blocks 2 are provided on both sides of the culvert body 1. Support grooves 3 are provided at both ends of the inner wall of the support block 2. A first installation port 4 is provided at the bottom of the support groove 3. Mounting blocks 5 are provided on both sides between the two support blocks 2. The mounting blocks 5 extend into the support grooves 3. The installation mechanism is provided between the mounting blocks 5 and the support blocks 2 for installing and fixing the support blocks 2 and the mounting blocks 5.

[0031] Reference Figures 1-4The installation mechanism includes a second mounting port, mounting posts 6, a first housing 7, and a positioning mechanism. The culvert body 1 has a second mounting port on one side of the first mounting port 4, aligned with the adjacent second mounting port. Two mounting posts 6 are fixedly mounted on the mounting block 5, extending through the first and second mounting ports and out of the culvert body 1. The first housing 7 is located on two opposite side walls of the culvert body 1, and has a first positioning port 8, through which the mounting posts 6 pass. The positioning mechanism is located between the first housing 7 and the mounting posts 6 for positioning them. A sealing ring 24 is fixedly mounted on the end of the mounting post 6 near the mounting block 5. The sealing ring 24 contacts the side wall of the support groove 3. Specifically, after the mounting block 5 extends into the support groove 3 and the mounting post 6 passes through the first mounting port 4 and the second mounting port, the mounting post 6 and the first housing 7 can be fixed by the operation of the positioning mechanism. Thus, the mounting block 5 and the support block 2 can be positioned by the cooperation of the mounting post 6 with the first mounting port 4 and the second mounting port, respectively. At the same time, the positioning of the culvert body 1 with the mounting block 5 and the first housing 7 can be achieved by the cooperation of the mounting post 6 with the mounting block 5 and the first housing 7, respectively. This facilitates the support of the culvert body 1 by the support block 2, thereby preventing the culvert body 1 from deforming under external force.

[0032] Reference Figures 2-5The positioning mechanism includes a positioning block 9, a second positioning port 10, a limiting mechanism, and a moving mechanism. The positioning block 9 is slidably disposed within the first housing 7. A second positioning port 10 is provided on one side of the first positioning port 8 on the positioning block 9. The mounting post 6 passes through the first positioning port 8 and the second positioning port 10. The limiting mechanism is disposed between the positioning block 9 and the mounting post 6 to limit the distance between the side wall of the second positioning port 10 and the mounting post 6. The moving mechanism is disposed between the first housing 7 and the positioning block 9 to adjust the position of the positioning block 9. The limiting mechanism includes a limiting port 11, a limiting groove 12, a limiting block 13, a first threaded rod 14, and a synchronous rotation mechanism. The limiting port 11 is provided on the mounting post 6. A limiting groove 12 is provided on the side wall of the second positioning port 10. The limiting block 13 is slidably disposed within the limiting groove 12. The limiting block 13 is located away from the limiting post 6. One end of the groove 12 extends into the limiting port 11. The first threaded rod 14 is rotatably disposed at the bottom of the limiting groove 12. The first threaded rod 14 extends into the limiting block 13 through threaded engagement. The synchronous rotation mechanism is disposed on the positioning block 9 and is used to drive the two first threaded rods 14 to rotate synchronously. Specifically, after the mounting post 6 passes through the first mounting port 4 and the second mounting port, the limiting port 11 and the limiting groove 12 can be aligned. Then, the synchronous rotation mechanism can drive the two first threaded rods 14 to rotate synchronously. Thus, the threaded engagement between the first threaded rod 14 and the limiting block 13 can drive the limiting block 13 to move and drive one end of the limiting block 13 to extend into the limiting port 11. This facilitates the limiting of the positioning block 9 and the mounting post 6 through the engagement of the limiting block 13 with the limiting groove 12 and the limiting port 11 respectively.

[0033] Reference Figures 3-5The synchronous rotation mechanism includes a first cavity 15, a second bevel gear 17, and a drive mechanism. The first cavity 15 is located within the positioning block 9. A first bevel gear 16 is rotatably mounted on the side wall of the first cavity 15 near the first threaded rod 14. The first bevel gear 16 is fixedly connected to the adjacent first threaded rod 14. The second bevel gear 17 is rotatably mounted on the side wall of the first cavity 15 and meshes with the first bevel gear 16. The drive mechanism is mounted on the positioning block 9 and is used to drive the second bevel gear 17 to rotate. The drive mechanism includes a first drive port 18, a second drive port 19, a drive prism 20, and a first handwheel 21. The first drive port 18 is located on the side wall of the first cavity 15. On the wall, the second drive port 19 is opened on the second bevel gear 17. The drive prism 20 is rotatably disposed in the first housing 7. The drive prism 20 passes through the first drive port 18 and the second drive port 19. The drive prism 20 is slidably connected to the side wall of the second drive port 19. The first handwheel 21 is rotatably disposed on the first housing 7. The first handwheel 21 is fixedly connected to the drive prism 20. Specifically, the rotation of the first handwheel 21 can drive the drive prism 20 to rotate. At the same time, the sliding engagement of the drive prism 20 with the second drive port 19 drives the second bevel gear 17 to rotate. In turn, the meshing of the second bevel gear 17 with the first bevel gear 16 drives the first threaded rod 14 to rotate.

[0034] Reference Figures 2-5 The moving mechanism includes a second threaded rod 22 and a second handwheel 23. The second threaded rod 22 is rotatably disposed within the first housing 7 and passes through the positioning block 9 via a threaded engagement. The second handwheel 23 is rotatably disposed on the first housing 7 and is fixedly connected to the second threaded rod 22. Specifically, after the positioning block 9 and the mounting post 6 are limited, the second threaded rod 22 can be rotated by rotating the second handwheel 23. At the same time, the positioning block 9 can be moved by the threaded engagement between the second threaded rod 22 and the positioning block 9. This allows for adjustment of the distance between the first housing 7 and the mounting base, thereby driving the first housing 7 to press against the culvert body 1 while simultaneously driving the mounting block 5 to press against the side wall of the support channel 3, which facilitates the improvement of the installation stability of the mounting block 5 and the support block 2.

[0035] In this embodiment, during use, the operator places the support block 2 on the upper and lower sides inside the culvert body 1. Then, the operator inserts the mounting block 5 into the support through groove 3, ensuring the mounting post 6 passes through the first mounting port 4 and the second mounting port. Next, the operator places the first housing 7 on the outer wall of the culvert body 1, ensuring the mounting post 6 passes through the first positioning port 8 and the second positioning port 10, while aligning the limiting port 11 with the limiting groove 12. The operator then rotates the first handwheel 21, which drives the drive prism 20 to rotate. Simultaneously, the sliding engagement of the second drive port 19 of the drive prism 20 drives the second bevel gear 17 to rotate. This, in turn, allows the second bevel gear 17 to mesh with the first bevel gear 16, driving the first threaded rod 14 to rotate. Thus, the first threaded rod 14 interacts with the limiting block 13. The threaded engagement drives the limiting block 13 to move and drives one end of the limiting block 13 to extend into the limiting port 11. This facilitates the limiting of the positioning block 9 and the mounting column 6 by the engagement of the limiting block 13 with the limiting groove 12 and the limiting port 11 respectively. Then, the operator rotates the handwheel, and the rotation of the second handwheel 23 drives the second threaded rod 22 to rotate. At the same time, the threaded engagement of the second threaded rod 22 with the positioning block 9 drives the positioning block 9 to move. This allows the distance between the first housing 7 and the mounting seat to be adjusted, thereby driving the first housing 7 to press against the culvert body 1 and the mounting block 5 to press against the side wall of the support through groove 3. This improves the installation stability of the mounting block 5 and the support block 2. At this time, the support block 2 can support the culvert body 1, thereby preventing the culvert body 1 from deforming.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
