[0001] The utility model relates to the technical field of bridge guardrails, and more specifically, to an assembled bridge anti-collision guardrail. Background Art
[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. With the rapid development of public transportation, bridges have been built in large numbers due to their characteristics of crossing rivers and shortening road mileage. A bridge guardrail refers to a guardrail installed on a bridge. Its purpose is to prevent pedestrians and out-of-control vehicles from going over the bridge. It has the function of preventing pedestrians and vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure.
[0003] Existing assembled bridge guardrails generally use multiple columns, and multiple beams are set between every two adjacent columns by screws, and the columns are connected with the beams to play a guardrail protection role.
[0004] However, in actual use, the existing guardrails are fixed with screws because the columns and crossbars are spliced and fixed by screws. When the guardrails are subjected to heavy external impact force, the surface of the guardrails is easily deformed due to the impact force, and the connection between the guardrails and the columns is easily deformed and falls off. When replacing the damaged guardrails, the connection between the crossbars and the columns will also be deformed, which will cause the screws to be squeezed, making it inconvenient for the staff to remove the screws, thereby affecting the efficiency of replacing the guardrails. Utility Model Content
[0005] The utility model provides an assembled bridge anti-collision guardrail to solve the following problems: the surface of the existing guardrail is easily deformed due to impact force, and the connection between the guardrail and the column is easily separated due to impact force. When the damaged guardrail is replaced, the connection between the crossbeam and the column will also be deformed, causing the screws to be squeezed, making it inconvenient for staff to remove the screws, thereby affecting the efficiency of replacing the guardrail.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled bridge anti-collision guardrail, including a bow-shaped guardrail, a column, and a positioning frame. The bow-shaped guardrail is installed on the outside of the bow-shaped guardrail through the positioning frame. The positioning frame is fixedly sleeved on the outside of the bow-shaped guardrail. Slides are slidably arranged inside both sides of the bow-shaped guardrail. Two mounting grooves are provided on the surface of the positioning frame. Removable mounting plates are arranged inside the two mounting grooves. The mounting plates are detachably connected to one end of the slide plate by screws. Two second buffer members are connected to the surface of the positioning frame. The mounting groove is arranged between the two second buffer members. The second buffer member is arranged between the bow-shaped guardrail and the positioning frame, which is beneficial to prevent the connection between the bow-shaped guardrail and the column from being damaged and difficult to repair when the bow-shaped guardrail is damaged.
[0007] In a preferred embodiment, a slide groove is provided on one side opposite to each of the two positioning frames, a limit block is slidably arranged inside the slide groove, a connecting plate is connected to the side of the limit block away from the positioning frame, and the outer end of the connecting plate is connected to the surface of the bow-shaped guardrail; a first buffer pad is fixedly arranged on the side of the slide groove away from the mounting groove, and a second buffer pad is fixedly connected to the connecting plate and the limit block on the side relative to the first buffer pad, which is beneficial to reduce the damage caused to the two ends of the bow-shaped guardrail by inertia when it is impacted.
[0008] In a preferred embodiment, a plurality of first buffer members are connected to the surface of the bow-shaped guardrail, and a buffer plate is commonly connected to the surfaces of the plurality of first buffer members. A through groove is formed through the surface of the buffer plate, and a plurality of rotating cylinders are arranged inside the through groove.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example
[0020] Refer to the instruction manual Figure 1-Figure 6 A prefabricated bridge anti-collision guardrail comprises a bow-shaped guardrail 1, a column 2, and a positioning frame 8. The bow-shaped guardrail 1 is installed on the outside of the bow-shaped guardrail 1 through the positioning frame 8. Slide plates 17 are slidably arranged inside both sides of the bow-shaped guardrail 1. The positioning frame 8 is fixedly sleeved on the outside of the bow-shaped guardrail 1. Two mounting grooves 9 are provided on the surface of the positioning frame 8. Both mounting grooves 9 are detachably provided with mounting plates 13. The mounting plate 13 is detachably connected to one end of the slide plate 17 by screws. Two second buffer members 12 are connected to the surface of the positioning frame 8. The mounting groove 9 is arranged between the two second buffer members 12, and the second buffer member 12 is arranged between the bow-shaped guardrail 1 and the positioning frame 8.
[0021] It should be noted that the material hardness of the positioning frame 8 is greater than that of the mounting plate 13, so that the torque force of the positioning frame 8 is greater than that of the mounting plate 13. When the arch-shaped guardrail 1 is damaged, only the mounting plate 13 will be damaged. When replacing the arch-shaped guardrail 1, the mounting plate 13 can be replaced together, thereby effectively preventing the arch-shaped guardrail 1 from being damaged and difficult to repair when its connection with the column 2 is damaged.
[0022] Furthermore, a slide groove 10 is provided on one side opposite to each of the two positioning frames 8, a limit block 15 is slidably arranged inside the slide groove 10, a connecting plate 14 is connected to the side of the limit block 15 away from the positioning frame 8, and the outer end of the connecting plate 14 is connected to the surface of the bow-shaped guardrail 1; a first buffer pad 11 is fixedly arranged on the side of the slide groove 10 away from the mounting groove 9, and a second buffer pad 16 is fixedly connected to the connecting plate 14 and the limit block 15 on the side relative to the first buffer pad 11.
[0023] In the above embodiment, when the bow-shaped guardrail 1 is subjected to external impact force, the bow-shaped guardrail 1 slides inside the slide groove 10 using the limit block 15. The limit block 15 can be limited by the slide groove 10 so that the two ends of the bow-shaped guardrail 1 slide in contact with the positioning frame 8 when subjected to impact, thereby effectively reducing the large deformation caused by the damage to both sides of the bow-shaped guardrail 1.
[0024] Furthermore, a plurality of first buffer members 7 are connected to the surface of the bow-shaped guardrail 1, and a buffer plate 3 is commonly connected to the surfaces of the plurality of first buffer members 7. A through groove 6 is penetrated through the surface of the buffer plate 3, and a plurality of rotating drums 4 are arranged inside the through groove 6; both ends of the plurality of rotating drums 4 are connected to connecting springs 5, and one end of the connecting spring 5 is fixedly connected to the surface of the through groove 6.
[0025] In the above embodiment, when an object contacts the rotating drum 4, the rotating drum 4 can roll along the direction of impact, which can produce a certain force relief effect on the impact force, and due to the elasticity of the connecting springs 5 and 7 themselves, the buffer plate 3 can intercept the impact object and mitigate its impact force while the rotating drum 4 rotates, playing a multiple buffering role and effectively improving the anti-collision ability.
[0026] Furthermore, the second buffer 12 is composed of a telescopic rod and a spring. The spring is sleeved outside the telescopic rod, and the spring is fixedly connected to both ends of the telescopic rod. The first buffer 7 and the second buffer 12 have the same structure.
[0027] In the above embodiment, when the telescopic rod is subjected to pressure, the spring is compressed at the same time, and the elasticity of the spring itself is used to push the telescopic rod in the opposite direction, thereby achieving a buffering function.
[0028] In this embodiment, the implementation scenario is specifically as follows: when the arched guardrail 1 is subjected to external impact force, the arched guardrail 1 first slides toward the direction of the first buffer pad 11 due to the force, and at the same time, the arched guardrail 1 drives the limit block 15 to slide inside the slide groove 10, and the limit block 15 of the slide groove 10 is limited so that the two ends of the arched guardrail 1 slide in contact with the positioning frame 8, so that one end of the arched guardrail 1 slides when it is impacted, thereby reducing the damage to the end of the arched guardrail 1, and at the same time, one end of the second buffer 12 is compressed by the pressure from the arched guardrail 1, and the spring arranged outside the telescopic rod pushes the arched guardrail 1 outward to relieve a certain amount of pressure, and when the object contacts the rotating drum 4, the rotating drum 4 can roll along the impact direction, which can produce a certain amount of force relief effect on the impact force, and due to the elasticity of the connecting springs 5 and 7 themselves, the impact object can be intercepted and the impact force of the impact object can be relieved by the buffer plate 3 while the rotating drum 4 rotates, thereby playing a multiple buffering role;
[0029] And because the mounting plate 13 is installed in the mounting groove 9 opened on the surface of the positioning frame 8, the torque force of the positioning frame 8 is greater than the mounting plate 13, and the mounting plate 13 will be damaged when the arched guardrail 1 is damaged. When replacing the arched guardrail 1, the mounting plate 13 can be replaced together, thereby effectively preventing the arched guardrail 1 from being damaged and difficult to repair when its connection with the column 2 is damaged.
[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
