Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge guardrails, in particular to a multi-section bridge guardrail which is convenient for maintenance and disassembly. Background Technique
[0002] Bridges are built as traffic facilities to cross rivers. At the same time, to ensure the safety of vehicles when passing through bridges, guardrails are installed on both sides of the bridges. The guardrails of many bridges are made of concrete structures. Although they can well prevent vehicles from rushing out of the bridges in case of a car accident, they cannot provide protection, and the vehicles will be severely damaged when impacted. For this reason, many bridges are made into railing-like structures, and anti-collision barrels are installed at the guardrails. After the vehicle is impacted, the anti-collision barrels will guide the vehicle and buffer the impact force, reduce the damage of the vehicle, and thus increase the survival rate of the passengers.
[0003] The existing anti-collision barrels are directly inserted into the guardrails. However, after long-term use, the guardrails will rust, resulting in the rotation of the anti-collision barrels being blocked, and the guiding and buffering forces during vehicle impact are reduced. For this reason, it is necessary to remove the upper railings every once in a while in order to take out the entire anti-collision barrel, which is convenient for maintaining the anti-collision barrel and the guardrail, but it is rather inconvenient; once impacted, a large section of the guardrail needs to be replaced, and the maintenance cost is relatively high. Content of the Utility Model
[0004] The purpose of the utility model is to provide a multi-section bridge guardrail which is convenient for maintenance and disassembly, so as to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A multi-section bridge guardrail which is convenient for maintenance and disassembly, including a support plate. The support plate is of a U-shaped structure. Connecting columns are fixedly connected to the inner walls of the upper end and the lower end of the support plate. A buffer column is arranged between the two connecting columns. Installation rings are sleeved in the middle of the two connecting columns. A plurality of fixing grooves are arranged on the inner wall of the installation ring. Elastic plates are arranged between adjacent two fixing grooves. A plurality of clamping balls are inlaid on the side ends of the elastic plates. A fixing plug is arranged at the upper installation ring. A plugging hole is arranged at the upper end of the buffer column. A connecting hole is arranged at the lower end of the buffer column. A plurality of support members are fixedly connected to the inner wall of the installation ring. A reinforcing plate is fixedly connected to the side end of the support plate. The reinforcing plate is of a herringbone structure. The reinforcing plate and the support plate form a plurality of triangular structures.
[0006] Preferably, a plurality of auxiliary plates are fixedly connected to the outer side wall of the installation ring. The distances between adjacent two auxiliary plates are the same. The lower installation ring is inserted into the connecting hole, and the upper installation ring is inserted and connected with the fixing plug.
[0007] Preferably, insertion plates are provided on both sides of the elastic plate. The elastic plate has an arc-shaped structure, and the insertion plate has a rectangular structure. The insertion plate and the elastic plate are integrally formed by stamping, and the insertion plate is inserted into the fixing groove.
[0008] Preferably, there is a gap between the top end of the support member and the elastic plate, and the front end of the support member has an annular structure.
[0009] Preferably, a plurality of clamping grooves are provided on the side end of the connecting column. The clamping grooves have an annular structure, and the clamping balls are clamped in the clamping grooves.
[0010] Preferably, the upper end of the fixing plug has a frustum-shaped structure, the lower end of the fixing plug has a cylindrical structure, and a limiting protrusion is fixedly connected to the side wall of the lower end of the fixing plug.
[0011] Preferably, the upper end of the insertion hole has a funnel-shaped structure, the lower end of the insertion hole has a circular hole-shaped structure, and a groove is provided on the inner wall of the lower end of the insertion hole.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Compared with the traditional anti-collision barrel directly inserted on the guardrail, the buffer column of the present utility model is spliced between two connecting columns. During maintenance, only need to lift the buffer column, so that the lower end of the buffer column can be moved away from the lower connecting column, and then the buffer column can be separated from the guardrail as a whole, and the maintenance is very convenient. When a collision occurs, the support plate of the present utility model has a lower probability of being damaged compared with the traditional guardrail structure.

[0017] Please refer to Figure 1-2 , the present utility model provides a technical solution: a multi-section bridge guardrail that is convenient for maintenance and disassembly, including a support plate 1. The support plate 1 is of a U-shaped structure. Connecting columns 3 are fixedly connected to the upper inner wall and the lower inner wall of the support plate 1. A buffer column 4 is provided between the two connecting columns 3. Mounting rings 9 are sleeved in the middle of the two connecting columns 3. A plurality of fixing grooves 11 are provided on the inner wall of the mounting ring 9. Elastic plates 13 are provided between adjacent two fixing grooves 11. A plurality of clamping balls 14 are embedded in the side ends of the elastic plates 13. A fixing plug 5 is provided at the upper mounting ring 9. A plug hole 7 is provided at the upper end of the buffer column 4, and a connecting hole 8 is provided at the lower end of the buffer column 4. A plurality of support members 16 are fixedly connected to the inner wall of the mounting ring 9. A reinforcing plate 2 is fixedly connected to the side end of the support plate 1. The reinforcing plate 2 is of a herringbone structure. The reinforcing plate 2 and the support plate 1 form a plurality of triangular structures. The reinforcing plate 2 can make the structure of the support plate 1 more firm, and the probability of damage is smaller when being impacted. This bridge guardrail adopts a splicing method, and the buffer column 4 can be directly separated from the support plate 1, which is convenient for maintaining the guardrail and the buffer column 4, and the maintenance cost is smaller when an impact occurs.
[0018] A plurality of auxiliary plates 10 are fixedly connected to the outer side wall of the mounting ring 9, and the distance between two adjacent auxiliary plates 10 is the same. The lower mounting ring 9 is inserted into the connection hole 8, and the upper mounting ring 9 is inserted into the fixing plug 5. Plug-in plates 12 are provided on both sides of the elastic plate 13. The elastic plate 13 is of an arc-shaped structure, and the plug-in plate 12 is of a rectangular structure. The plug-in plate 12 and the elastic plate 13 are integrally formed by stamping. The plug-in plate 12 is inserted into the fixing groove 11. There is a gap between the top end of the support member 16 and the elastic plate 13. The front end of the support member 16 is of an annular structure. A plurality of clamping grooves 15 are provided on the side end of the connecting column 3. The clamping grooves 15 are of a ring-shaped structure. The clamping balls 14 are clamped in the clamping grooves 15. The upper end of the fixing plug 5 is of a frustum-shaped structure, and the lower end of the fixing plug 5 is of a cylindrical structure. A limiting protrusion 6 is fixedly connected to the side wall of the lower end of the fixing plug 5. The upper end of the insertion hole 7 is of a funnel-shaped structure, and the lower end of the insertion hole 7 is of a circular hole-shaped structure. A groove is provided on the inner wall of the lower end of the insertion hole 7. When installing the buffer column 4 on the support plate 1, first insert the two mounting rings 9 into the middle of the fixing plug 5 and the lower end of the buffer column 4 respectively, and then sleeve the fixing plug 5 with the upper connecting column 3. At this time, insert the insertion hole 7 of the buffer column 4 into the upper connecting column 3. Since the diameter of the insertion hole 7 is larger than the diameter of the connecting column 3, the angle of the buffer column 4 can be adjusted until the buffer column 4 is in a vertical state. At this time, move the buffer column 4 downward so that the mounting ring 9 below the buffer column 4 is inserted into the lower connecting column 3, and then move the fixing plug 5 so that the fixing plug 5 is inserted into the insertion hole 8, thereby restricting the buffer column 4 so that the buffer column 4 can only rotate around the connecting column 3. The clamping balls 14 can reduce the friction force when the buffer column 4 rotates. The support member 16 increases the structural strength of the mounting ring 9 and can reduce the deformation degree of the mounting ring 9 when the vehicle is impacted.
