Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to an anti-collision buffer guardrail structure for bridge engineering. Background Art

[0002] A bridge is a construction structure for vehicles and pedestrians to cross obstacles, and is an extension or connection of a line crossing an obstacle. Highway bridges are equipped with anti-collision guardrails to prevent out-of-control vehicles from going over the bridge, to prevent vehicles from breaking through, passing under, or climbing over the bridge, to beautify the bridge structure, and to provide edge limiting functions.

[0003] The existing anti-collision guardrail improves the strength of the anti-collision plate during use by arranging springs, movable rods and anti-collision plates, and effectively cushions out-of-control vehicles. However, the speed of out-of-control vehicles is generally high, and when they hit the guardrail, not only will a strong impact force be generated, but the vehicle is also likely to roll over and over the guardrail. Although the existing device reduces the impact force when the vehicle collides through the buffering of the spring, the height of the guardrail is fixed, and it cannot effectively play a blocking role when the vehicle rolls over. Based on this, an anti-collision buffer guardrail structure for bridge engineering is proposed. Utility Model Content

[0004] The utility model provides an anti-collision buffer guardrail structure for bridge engineering, which is used to solve the problem that the guardrail of the existing anti-collision device mentioned in the above technical background has a fixed height and cannot effectively play a blocking role when a vehicle collides and rolls over.

[0007] Preferably, a buffer spring is fixedly connected to the top of the sliding block, and the other end of the buffer spring surrounds the sliding rod and is fixedly connected to the bottom of the mounting block.

[0008] Preferably, the number of the first through slots and the number of the second through slots are both five, and the first through slots and the second through slots are symmetrically distributed about the mid-perpendicular line of the baffle.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model sets a lifting plate in the baffle. When the anti-collision plate is hit and moves toward one side of the baffle, the guide rod is driven to slide in the hollow tube and exert force on the shock-absorbing spring, causing the shock-absorbing spring to deform and provide a buffering and shock-absorbing effect. When the baffle moves, the movable rod drives the lifting plate to move upward, so that the height of the baffle is increased, the protective effect of the baffle is improved, and the risk of the vehicle falling over the guardrail and going out of the bridge when it hits and overturns is reduced.

[0014] (2) The utility model can increase the stability of the lifting plate when it moves up and down and improve the buffering effect of the device when it is hit by an impact by arranging a sliding rod, a sliding block and a buffer spring on the other side of the baffle.

[0015] (3) The utility model provides buffer columns on the surface of the anti-collision plate. When a fast-moving car collides with the anti-collision plate, the multiple buffer columns on the surface of the anti-collision plate rotate, thereby unloading the impact force and further improving the protective effect of the anti-collision plate.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

When the anti-collision plate 7 is impacted and moves toward the side of the baffle 3, the movable rod 11 drives the lifting plate 9 to move upward, so that the height of the baffle 3 is increased, thereby improving the protective effect of the baffle 3 and reducing the risk of the vehicle overturning and tipping over the guardrail and going out of the bridge when impacting.

[0022] A plurality of second through slots 13 communicating with the cavity 8 are evenly formed on the side of the baffle plate 3 away from the anti-collision plate 7, mounting blocks 14 are fixedly provided at the upper and lower ends of the second through slots 13, a slide bar 15 is fixedly provided between the mounting blocks 14, a slide bar 12 is fixedly connected to the lower side wall of the lifting plate 9, the slide bar 12 passes through the second through slots 13 and is slidably connected to the slide bar 15, and by providing the slide bar 15 and the slide bar 12, the stability of the lifting plate 9 is further increased when it moves up and down.

[0023] A buffer spring 16 is fixedly connected to the top of the slider 12, and the other end of the buffer spring 16 surrounds the slide rod 15 and is fixedly connected to the bottom of the mounting block 14. When the movable rod 11 drives the lifting plate 9 to move upward, the buffer spring 16 is compressed to further improve the buffering effect of the device when it is hit.

[0024] The number of the first through slots 10 and the number of the second through slots 13 are both five, and the first through slots 10 and the second through slots 13 are symmetrically distributed about the mid-perpendicular line of the baffle 3 .
