Description

Technical Field

[0001] The utility model relates to the technical field of road guardrail structures, in particular to a guardrail with an extended structure. Background Art

[0002] There are many types of road guardrails. According to different materials and uses, they can be divided into corrugated beam guardrails, cable guardrails, concrete guardrails, etc. Corrugated beam guardrails are widely used in scenes such as highways and urban roads due to their high strength, corrosion resistance, and beautiful appearance; cable guardrails are widely used in roads in mountainous areas and scenic spots due to their good flexibility and wide field of vision; concrete guardrails play an important role in bridges, tunnels and other projects due to their durability and low maintenance costs.

[0003] In the prior art, guardrails are installed in the middle of some bridges, mainly to separate vehicles traveling in two directions and reduce the probability of traffic accidents. However, some bridges or terrains have a certain slope. Therefore, when two guardrails are connected at a certain angle on the ground, the inclination angle of the ground makes it difficult to connect the two guardrails at their docking structure, thereby reducing the stability of this part of the guardrail, thereby affecting the separation of the road and the protection of the vehicle. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a guardrail with an extended structure so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A guardrail with an extended structure comprises two support columns, wherein upper and lower ends of opposite sides of the two support columns are respectively fixedly connected with an upper positioning rod and a lower positioning rod, a gap is left between two adjacent upper positioning rods, a gap is left between two adjacent lower positioning rods, an adjusting piece is arranged between two adjacent upper positioning rods, and a stabilizing piece is arranged between two adjacent lower positioning rods.

[0007] In a preferred example, the utility model can be further configured as follows: the adjusting member includes a positioning clamp block, the end of which is fixedly connected to the end of one of the upper positioning rods, and the top side of the positioning clamp block is rotatably connected to a worm.

[0008] In a preferred embodiment, the present utility model can be further configured as follows: A connecting rod is fixedly connected to the end of the upper positioning rod away from the positioning clamp block. A semi-circular worm gear is fixedly connected to the end of the connecting rod. A rotating rod is rotatably connected to the connection between the semi-circular worm gear and the connecting rod. The rotating rod is fixedly connected to the positioning clamp block. The semi-circular worm gear meshes with the worm.

[0009] In a preferred embodiment, the present utility model can be further configured as follows: The stabilizing member includes a perforation, which is opened at the end of one of the lower positioning rods. Bent rods are rotatably connected to both ends of the perforation.

[0010] In a preferred embodiment, the present utility model can be further configured as follows: A telescopic joint is fixedly connected to the end of the lower positioning rod away from the bent rod. The ends of the telescopic joints are rotatably connected to the ends of the two bent rods.

[0011] In a preferred embodiment, the present utility model can be further configured as follows: A number of auxiliary support rods are connected between adjacent upper positioning rods and lower positioning rods.

[0012] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0013] 1. When the protective fence with an extension structure is in use, the entire protective fence can be adjusted through the provided adjusting member, enabling the protective fence to adapt to the slope on the bridge, so that the protective fence can be stably laid on the bridge. At the same time, the provided stabilizing member can be used to position the bottom of the protective fence and improve the stability of the protective fence, preventing the protective fence from shifting to the side.

[0014] 2. When the protective fence with an extension structure is being adjusted, if the ground is in a sunken state, at this time, rotate the worm. When the worm rotates, it will drive the semi-circular worm gear to rotate counterclockwise. Thus, the connecting rod is driven to rotate counterclockwise by the semi-circular worm gear, and then the upper positioning rod and the corresponding support column connected to the connecting rod are driven to rotate counterclockwise, so as to adjust the angle between the two support columns and facilitate adapting to the position of the sunken ground state.

[0015] 3. When the protective fence with an extension structure is in use and no adjustment is required, the two support columns can be directly installed in an appropriate place. When encountering a sloping ground, at this time, the angle of the two upper positioning rods is adjusted through the adjusting member, so as to adjust the angle of the two support columns. The gap between the two upper positioning rods and the two lower positioning rods is used to provide space for the angle adjustment of the upper positioning rod and the lower positioning rod. The stabilizing member provided is used to prevent the lower positioning member from shifting to the side due to external factors during use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] The following further details the present utility model in conjunction with the drawings.

[0022] Embodiment:

[0023] Refer to Figures 1-3 , a guardrail with an extension structure disclosed by the present utility model includes two support columns 1. The upper and lower ends of the opposite sides of the two support columns 1 are respectively fixedly connected with an upper positioning rod 2 and a lower positioning rod 3. There are gaps between adjacent two upper positioning rods 2, and there are gaps between adjacent two lower positioning rods 3. An adjusting member 4 is arranged between adjacent two upper positioning rods 2, and a stabilizer 5 is arranged between adjacent two lower positioning rods 3.

[0024] In this embodiment, when in use and no adjustment is required, the two support columns 1 can be directly installed in an appropriate place. When encountering a sloping ground, at this time, the adjusting member 4 is used to adjust the angles of the two upper positioning rods 2, so as to adjust the angles of the two support columns 1. The gaps left between the two upper positioning rods 2 and the two lower positioning rods 3 are used to provide space for the angle adjustment of the upper positioning rod 2 and the lower positioning rod 3. The arranged stabilizer 5 is used to prevent the lower positioning member from shifting to the side due to external factors during use.

[0025] In a further preferred embodiment of the present utility model, as Figures 1-3As shown, the adjusting member 4 includes a positioning clamping block 6. The end of the positioning clamping block 6 is fixedly connected to the end of one of the upper positioning rods 2. A worm 7 is rotatably connected to the top side of the positioning clamping block 6. The end of the upper positioning rod 2 away from the positioning clamping block 6 is fixedly connected to a connecting rod 8. The end of the connecting rod 8 is fixedly connected to a semi-circular worm gear 9. A rotating rod 10 is rotatably connected to the connection between the semi-circular worm gear 9 and the connecting rod 8. The rotating rod 10 is fixedly connected to the positioning clamping block 6. The semi-circular worm gear 9 meshes with the worm 7.

[0026] In this embodiment, when adjusting, if the ground is in a concave state, at this time, rotate the worm 7. When the worm 7 rotates, it will drive the semi-circular worm gear 9 to rotate counterclockwise, thereby driving the connecting rod 8 to rotate counterclockwise through the semi-circular worm gear 9, and further driving the upper positioning rod 2 and the corresponding support column 1 connected to the connecting rod 8 to rotate counterclockwise, so as to adjust the angle between the two support columns 1, and further facilitate adapting to the position of the ground concave state;

[0027] If the ground is in a convex state, at this time, rotate the worm 7 to drive the semi-circular worm gear 9 to rotate clockwise, thereby driving the connecting rod 8 to rotate clockwise through the semi-circular worm gear 9, and further driving the upper positioning rod 2 connected to the connecting rod 8 to rotate clockwise, so that the support column 1 connected to it rotates clockwise, so as to adjust the angle between the two support columns 1, and further facilitate adapting to the position of the ground convex state, so that the protective fence can adapt to the bridge slope through this extended structure.

[0028] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, the stabilizing member 5 includes a through hole 11. The through hole 11 is opened at the end of one of the lower positioning rods 3. Bent rods 12 are rotatably connected to both ends of the through hole 11. The end of the lower positioning rod 3 away from the bent rod 12 is fixedly connected to a telescopic joint 13. The ends of the telescopic joint 13 are rotatably connected to the ends of the two bent rods 12.

[0029] In this embodiment, after the angle of the protective fence is adjusted, first pull out the telescopic joint 13 to a suitable position, then insert the two bent rods 12 into both ends of the through hole 11 and rotate to a suitable angle, and then insert the ends of the two bent rods 12 into the outer peripheral wall of the extended end of the telescopic joint 13;

[0030] In addition, the bent rod 12 can be inserted into the through hole 11 before adjustment. Subsequently, the end of the bent rod 12 is directly inserted into the outer peripheral wall of the telescopic end of the telescopic joint 13. When adjusting, if the two lower positioning rods 3 approach each other, the bent rod 12 and the through hole 11 are rotatably connected. Therefore, the telescopic joint 13 can be pushed to contract and the angle can be automatically adjusted. If the two lower positioning rods 3 move away from each other, the two bent rods 12 will pull the telescopic joint 13 out. At the same time, the bent rod 12 can rotate automatically by a corresponding angle, so as to avoid the side shift of the guardrail.

[0031] In a further preferred embodiment of the present invention, as Figure 1 shown, a number of auxiliary support rods 14 are connected between two adjacent upper positioning rods 2 and the lower positioning rods 3.

[0032] In this embodiment, the provided auxiliary support rods 14 support the adjacent upper positioning rods 2 and the lower positioning rods 3, mainly for the main support of the entire guardrail, thereby improving the stability of the entire guardrail.

[0033] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
