Description

Technical Field

[0001] The present application relates to the technical field of guardrails, and in particular to a sidewalk guardrail. Background Art

[0002] The sidewalk refers to the part of the road in the middle that is separated by curbs, guardrails and other similar facilities and is reserved for pedestrians. In order to fully protect pedestrians, guardrails are often installed between the sidewalk and the motor vehicle lane. This can effectively constrain pedestrians to comply with traffic laws and reduce the occurrence of traffic accidents. It has been widely used in road traffic.

[0003] A reinforced pedestrian roadside isolation guardrail mentioned in the existing Chinese public patent (authorization announcement number: CN220225062U) can be connected to each other through a plurality of first cross plates and a second cross plate through columns. When the utility model is subjected to a certain force in a certain section of the Z-axis direction, the spring, damping rubber sleeve and other series of structures on the buffer mechanism of this section and adjacent sections of the guardrail can play a buffering role under the cooperation of the buffer mechanism, thereby reducing the impact force received by the utility model. Thus, the utility model effectively enhances the impact resistance and avoids the situation where the utility model is tipped over or even damaged due to a certain external impact force. The setting of the spring and the damping rubber sleeve can play a damping role and avoid the spring being in a compressed rebound state for a long time, that is, a single section of the guardrail has a buffering effect, and adjacent sections of the guardrail all have a buffering effect.

[0004] In the existing method of splicing guardrails, multiple bolts are mostly used to connect and fix the connecting surfaces of the guardrails on both sides, which is simple and easy. However, when splicing or disassembling more guardrails, workers are required to manually install and disassemble multiple bolts, which is cumbersome, thereby increasing the work intensity of the workers and being inconvenient.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] An embodiment of the present application discloses a sidewalk guardrail.

[0034] Reference Figure 1 and Figure 2 A pedestrian guardrail 1 includes a guardrail 1, two ends of the guardrail 1 are fixedly connected with columns 2, the bottom of the column 2 is fixedly connected with a bottom plate 3, the inside of the guardrail 1 is fixedly connected with a plurality of reinforcing plates 4, the reinforcing plates 4 are arranged in an inclined shape, a connecting mechanism is arranged inside the column 2 on one side, and supporting mechanisms are arranged on both sides of the column 2.

[0035] When protecting the sidewalk, the base plate 3 is placed on one side of the road, and the sidewalk is protected by the guardrail 1 between the columns 2 on both sides. When the guardrail 1 protects the sidewalk, the protection strength of the guardrail 1 can be increased by the reinforcement plate 4. When protecting, the splicing of the guardrails 1 on both sides can be quickly completed through the connecting mechanism, thereby improving work efficiency. The protection strength of the guardrail 1 can be enhanced by the reinforcement mechanism, making the protection strength of the guardrail 1 higher.

[0036] Reference Figure 1 , Figure 2 and Figure 3The connecting mechanism includes a long hole 9 opened on the side of one side column 2, a connecting block 8 is slidably connected inside the long hole 9, a vertical block 10 is fixedly connected to one end of the connecting block 8 away from the column 2, and a fixed block 11 is fixedly connected to the side of the other side column 2, a vertical groove 12 is opened inside the fixed block 11, the vertical block 10 and the vertical groove 12 are slidably arranged, and a driving member is arranged inside the column 2.

[0037] Among them, the driving part includes an empty groove 5 opened inside the side column 2, the empty groove 5 is connected with the long strip hole 9, a threaded rod 6 is arranged inside the empty groove 5, the bottom end of the threaded rod 6 is rotatably connected to the inner wall of the empty groove 5, the top end of the threaded rod 6 passes through the column 2 and is fixedly connected with a handle, the outer surface of the threaded rod 6 is threadedly connected with a threaded block 7, and the threaded block 7 is fixedly connected to the connecting block 8.

[0038] In addition, an auxiliary rod 25 is slidably connected inside the threaded block 7 , and both ends of the auxiliary rod 25 are fixedly connected to the inner wall of the empty groove 5 .

[0039] When it is necessary to splice the guardrails 1 on both sides, first place the guardrails 1 on both sides together, and after alignment, drive the threaded rod 6 to rotate by turning the handle. After the threaded rod 6 rotates, it drives the threaded rod 6 to move horizontally on the outer surface of the threaded block 7, and when the threaded block 7 moves, it drives the connecting block 8 to move inside the long hole 9. After the connecting block 8 moves, it drives the vertical block 10 to enter the vertical groove 12 of the fixing block 11, so as to fix the guardrails 1 on both sides, so that the splicing between the guardrails 1 on both sides can be completed quickly, saving installation time, thereby improving work efficiency and facilitating the use of the staff. When the threaded block 7 is moving, it is slidably connected to the threaded block 7 through the auxiliary rod 25. The auxiliary rod 25 provides an additional support point for the threaded block 7, so that the threaded block 7 is more stable when moving.

[0040] Reference Figure 2 and Figure 3 A reinforcement groove 13 is provided inside the fixed block 11, and an elastic member 14 is arranged inside the reinforcement groove 13. One end of the elastic member 14 is fixedly connected to the reinforcement groove 13, and the other end of the elastic member 14 is fixedly connected to a moving block 15. A side of the moving block 15 away from the elastic member 14 is fixedly connected to a locking block 16. A locking groove 17 is provided on one side of the vertical block 10, and the locking block 16 is locked and connected to the locking groove 17.

[0041] The engaging block 16 and the engaging groove 17 are both configured in a semicircular shape.

[0042] In addition, sliding grooves 18 are provided on the inner walls of both sides of the reinforcement groove 13 , and sliding blocks are fixedly connected to both sides of the moving block 15 , and the sliding blocks are slidably connected to the sliding grooves 18 .

[0043] When the vertical block 10 enters the vertical slot 12, the vertical block 10 will contact the locking block 16, so that the locking block 16 is forced to move, and the locking block 16 moves to drive the moving block 15 to move. The movement of the moving block 15 causes the telescopic rod and the spring to be compressed to generate elastic potential energy. As the vertical block 10 continues to move, when the locking groove 17 moves to the locking block 16, the elastic potential energy of the spring is released, so that the locking block 16 enters the inside of the locking groove 17, thereby further improving the connection strength between the guardrails 1 on both sides, making the guardrails 1 on both sides tighter and firmer. When it needs to be taken out, the locking block 16 and the locking groove 17 are set as a semicircle, and the threaded rod 6 is used to drive the vertical block 10 to move upward. Under the sliding action of the arc surface, the locking block 16 is disengaged from the locking groove 17, thereby facilitating the staff to disassemble. When the moving block 15 is moving, the slider and the slide groove 18 can provide a guiding effect for the moving block 15, so that the movement of the moving block 15 is more stable.

[0044] refer to Figure 1 and Figure 2 The supporting mechanism includes a rotating seat 19 fixedly connected to both sides of the column 2, the rotating seat 19 is rotatably connected to a telescopic sleeve 20, the telescopic sleeve 20 is slidably connected to a telescopic sleeve rod 21, the bottom end of the telescopic sleeve rod 21 is rotatably connected to a contact plate 22, and the contact plate 22 is fixedly connected to the bottom plate 3 by screws.

[0045] A plurality of thread grooves 23 are provided on one side of the telescopic sleeve 21 , and a bolt 24 is slidably provided on one side of the telescopic sleeve 20 , and the bolt 24 is threadedly connected with the thread groove 23 .

[0046] When supporting the guardrail 1, first rotate the telescopic sleeve 20 inside the rotating seat 19. When it is rotated to a suitable angle, pull the telescopic sleeve rod 21 out of the telescopic sleeve 20 so that the contact plate 22 overlaps the bottom of the base plate 3. Then use screws to fix the contact plate 22 and the base plate 3, so that a triangle is formed between the column 2, the base plate 3 and the telescopic sleeve rod 21, which can effectively disperse and absorb impact force, enhance the impact resistance of the guardrail 1, and thus improve the protective effect of the guardrail 1. When the telescopic sleeve rod 21 slides to a suitable position inside the telescopic sleeve 20, the bolt 24 passes through the telescopic sleeve 20 and is threadedly connected with the thread groove 23, so that the telescopic sleeve rod 21 is fixed inside the telescopic sleeve 20. By rotating the telescopic sleeve 20 and adjusting the length of the telescopic sleeve rod 21, it can be adjusted as needed to adapt to changes in different sites and requirements.

[0047] Working principle: Place the bottom plate 3 on one side of the road, and protect the sidewalk through the guardrail 1 between the two side columns 2. When the guardrail 1 protects the sidewalk, the protection strength of the guardrail 1 can be increased by the reinforcement plate 4. Place the guardrails 1 on both sides together, align them, and then drive the threaded rod 6 to rotate by turning the handle. After the threaded rod 6 rotates, it drives the threaded rod 6 to move horizontally on the outer surface of the threaded block 7. When the threaded block 7 moves, it drives the connecting block 8 to move inside the long hole 9. After the connecting block 8 moves, it drives the vertical block 10 to enter the vertical groove 12 of the fixing block 11, so as to fix the guardrails 1 on both sides, so that the splicing between the guardrails 1 on both sides can be quickly completed;

[0048] When the vertical block 10 enters the vertical groove 12, the vertical block 10 will contact the locking block 16, causing the locking block 16 to move under force. When the locking groove 17 moves to the locking block 16, the elastic potential energy of the spring is released, causing the locking block 16 to enter the inside of the locking groove 17, thereby further improving the connection strength between the guardrails 1 on both sides. The telescopic sleeve 20 is rotated inside the rotating seat 19. When it is rotated to a suitable angle, the telescopic sleeve rod 21 is pulled out of the telescopic sleeve 20, so that the contact plate 22 overlaps the bottom of the bottom plate 3. Then, screws are used to fix the contact plate 22 and the bottom plate 3, so that the column 2, the bottom plate 3 and the telescopic sleeve rod 21 form a triangle, which can effectively disperse and absorb impact force and enhance the impact resistance of the guardrail 1.
