DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. Embodiment 1

[0033] As shown in the figure; Figures 1 to 6

[0034] In order to realize the rotation, the rotatable width and height limiting device for water conservancy projects, including the width limiting column 1 arranged symmetrically, the top of the width limiting column 1 on any side is provided with a rotating structure 2;

[0035] ​The rotating structure 2 includes a circular plate 21, which is fixedly connected to the top of the adjacent width-limiting column 1. A fixed column 22 is fixedly connected to the top surface of the circular plate 21. A sleeve 23 is rotatably connected to the outer wall of the fixed column 22. A first flange 24 is fixedly connected to the top of the sleeve 23. An annular plate 25 is slidably connected to the outer wall of the sleeve 23. Several positioning holes 27 are provided on the circular plate 21 in a ring arrangement. Positioning rods 26 are fixedly connected to the bottom surface of the annular plate 25 near the positioning holes 27.

[0036] In this implementation scheme: Under normal circumstances, the positioning rod 26 is set in the positioning hole 27, so that the positioning rod 26 limits the annular plate 25 and the sleeve 23, preventing the height limiting structure 3 installed on the first flange 24 from rotating. When it is necessary to release the height restriction, the annular plate 25 can be lifted, so that the annular plate 25 drives the positioning rod 26 to disengage from the positioning hole 27, so that the annular plate 25 is no longer limited. Then the annular plate 25 can be rotated. When the annular plate 25 rotates, it will drive the sleeve 23 to rotate, so that the sleeve 23 drives the first flange 24 and the height limiting structure 3 installed on the first flange 24 to rotate together, thereby releasing the height restriction, facilitating the entry and exit of taller engineering vehicles or trucks, and improving the convenience of use.

[0037] Furthermore, such as Figures 3 to 5 As shown, in order to guide the annular plate 25, in an optional embodiment, a plurality of guide grooves 28 arranged in a ring are provided on the inner wall of the annular plate 25, and guide blocks 29 are fixedly connected to the outer wall of the sleeve 23 near the guide grooves 28.

[0038] In this embodiment, the guide groove 28 and guide block 29 can guide the lifting and lowering movement of the annular plate 25, and at the same time enable the annular plate 25 to stably drive the sleeve 23 to rotate.

[0039] Furthermore, such as Figures 3 to 5 As shown, in conjunction with the above, in order to facilitate the rotation of the annular plate 25, in an optional embodiment, a first connecting block 212 is fixedly connected to both sides of the annular plate 25. Each first connecting block 212 has a connecting hole 213, and a connecting rod 210 is provided in each connecting hole 213. A positioning ring 214 is fixedly connected to the bottom and top surfaces of each connecting rod 210. A second connecting block 215 is fixedly connected to the first flange 24 near the first connecting block 212. Each second connecting block 215 has a threaded hole 216, and a threaded post 211 is fixedly connected to the top of each connecting rod 210.

[0040] In this embodiment: when it is necessary to rotate the annular plate 25, the connecting rods 210 on both sides can be lifted, so that the connecting rods 210 drive the annular plate 25 to move upward under the action of the positioning ring 214, so that the threaded post 211 moves to the position of the second connecting block 215. Then, the connecting rods 210 on both sides are rotated, so that the threaded post 211 is connected in the nearby threaded hole 216, and the position of the connecting rod 210 is fixed. This allows the operator to rotate the annular plate 25 without having to lift the connecting rod 210 all the time, which is convenient for the operator to use.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, in conjunction with the above, in order to facilitate the use of the connecting rod 210, in an optional embodiment, a handle 217 is fixedly connected to the bottom end of each connecting rod 210.

[0042] In this embodiment, the connecting rod 210 can be easily lifted by the operator using the handle 217.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, in order to adjust the width restriction distance, in an optional embodiment, a height restriction structure 3 is provided on the top surface of the first flange 24;

[0044] The height restriction structure 3 includes a second flange 31, a first connecting post 32 fixedly connected to the top surface of the second flange 31, a first height restriction post 33 fixedly connected to the outer wall of the first connecting post 32, a connecting groove 34 formed at the end of the first height restriction post 33 away from the first connecting post 32, a third flange 36 fixedly connected to the top of the width restriction post 1 on the side away from the first connecting post 32, a fourth flange 37 provided on the top surface of the third flange 36, a second connecting post 38 fixedly connected to the top surface of the fourth flange 37, and the second connecting post 38 being close to the first height restriction post. A second height-limiting column 39 is fixedly connected to one side of the first height-limiting column 33. A connecting plate 310 is fixedly connected to the end of the second height-limiting column 39 away from the second connecting column 38. A threaded rod 311 is fixedly connected to the side of the connecting plate 310 away from the second height-limiting column 39. A threaded ring 35 is rotatably connected to the end of the first height-limiting column 33 near the second height-limiting column 39. The threaded rod 311 is set in the connecting groove 34 and threadedly connected to the threaded ring 35. The second flange 31 is fixedly connected to the first flange 24 by bolts. The fourth flange 37 is fixedly connected to the third flange 36 by bolts.

[0045] In this embodiment: by rotating the threaded ring 35, the threaded rod 311 can be moved within the connecting groove 34, thereby enabling the threaded rod 311 to move the second height limiting post 39, adjusting the distance between the two width limiting posts 1, and thus adjusting the width of the restriction. This allows workers to adjust the width of the restriction according to the road or entrance conditions before installing the width and height limiting device, making the width and height limiting device adaptable to different installation requirements and improving its applicability.

[0046] Furthermore, such as Figure 7 As shown, in order to protect the threaded rod 311, in an optional embodiment, a protective cover 312 is fixedly connected to the side of the connecting plate 310 near the threaded rod 311.

[0047] In this embodiment, the threaded rod 311 can be protected by the protective cover 312, thereby extending the service life of the threaded rod 311.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, in conjunction with the above, in order to provide stable support for the width and height limiting device, in an optional embodiment, a base 11 is fixedly connected to the bottom end of each width limiting column 1, and a support column 12 is symmetrically fixedly connected to the outer wall of the bottom end of each width limiting column 1. The support columns 12 are respectively fixedly connected to the top surface of the adjacent base 11.

[0049] In this embodiment, the base 11 and the support column 12 can provide stable support for the width-limiting column 1, thereby improving the stability of the width-limiting column 1.

[0050] The working principle and usage process of this utility model are as follows: First, before installing the width and height limiting device, the width of the restriction is adjusted according to the road or entrance conditions. By rotating the threaded ring 35, the threaded rod 311 can be moved within the connecting groove 34, thereby allowing the threaded rod 311 to move the second height limiting column 39, adjusting the distance between the two width limiting columns 1, and thus adjusting the width of the restriction. This allows the width and height limiting device to adapt to different installation requirements. Normally, the positioning rod 26 is set in the positioning hole 27, limiting the annular plate 25 and the sleeve 23 to prevent the height limiting structure 3 installed on the first flange 24 from rotating. When taller engineering vehicles or trucks need to enter or exit, the connecting rod 210 is lifted by using the handle 217, causing the connecting rod 210 to be positioned within the positioning ring 21. Under the action of 4, the annular plate 25 is driven to move upward, causing the threaded column 211 to move to the position of the second connecting block 215. Then, the connecting rods 210 on both sides are rotated, so that the threaded column 211 is connected in the nearby threaded hole 216, and the position of the connecting rod 210 is fixed. This allows the operator to rotate the annular plate 25 without constantly lifting the connecting rod 210, causing the annular plate 25 to drive the positioning rod 26 to disengage from the positioning hole 27, thus freeing the annular plate 25 from being limited. Then, the annular plate 25 can be rotated. When the annular plate 25 rotates, it will drive the sleeve 23 to rotate, causing the sleeve 23 to drive the first flange 24 and the height limiting structure 3 installed on the first flange 24 to rotate together, thereby removing the height restriction, facilitating the entry and exit of taller engineering vehicles or trucks, and improving the convenience of use.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
