Embodiment Construction

[0016] Combine below Figure 1-4 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.

[0017] combined with Figure 1-4 The described bridge impact buffering safety fence comprises a bridge deck 10, the upper end wall of which is provided with a buffer cavity 11 connected to the outside, and the upper side of the bridge deck 10 is provided with three cross bars 34 and three vertical bars. The bar 27 and the cross bar 34 and the vertical bar 27 are vertically fixed to each other. The bridge deck 10 is provided with a rotating mechanism 62 for supporting the vertical bar 27 on the left and right sides. The cross bar 34 is provided with There is a connecting mechanism 60 for connecting other guardrails. The uppermost cross bar 34 is slidably connected with four rotating b...

Abstract

The invention discloses a bridge impact buffering safety guardrail. The bridge impact buffering safety guardrail includes a deck, and a buffer cavity of which the upper end wall is communicated with the outside is formed in the bridge deck; three transverse rods and three vertical rods are arranged on the upper side of the bridge deck, and the transverse rods and the vertical rods are perpendicularly fixed. A rotating mechanism used for supporting the vertical rods on the left side and the right side is arranged in the bridge deck. Connecting mechanisms used for being connected with other guardrails are arranged in the transverse rods. Four rotating blocks penetrated by the transverse rods are connected to the transverse rod on the uppermost side in a sliding manner; the bridge impact buffering safety guardrail is simple in structure and convenient in operation, and through mechanical transmission, buffering is provided for a vehicle directly impacting the guardrails, so that harm to personnel in the vehicle is reduced, an upper-layer guardrail is provided in the guardrail moving process, the vehicle is prevented from turning over, when the connecting position of the two guardrailsis impacted, guardrail rotation can also provide buffering during guardrail rotation buffering, and the vehicle is prevented from impacting the weak connecting position and being away from the guardrails.

Description

technical field [0001] The invention relates to the field of bridge protection, in particular to a bridge impact buffer safety protection fence. Background technique [0002] With the development of technology, various places are gradually connected, and bridges are no longer a minority. When vehicles are driving on bridges, guardrails must be set up to prevent vehicles from driving off the bridge in accidents; [0003] At this stage, most of the cement guardrails are fixed on the bridge deck. Although the cost is cheap, when the vehicle hits, it cannot provide buffering and can only prevent the vehicle from driving off the bridge deck. Although some existing anti-collision guardrails provide buffering, some It does not prevent rollovers, etc. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a bridge impact buffer safety fence, which overcomes the safety problems of the fence, thereby improving the protection saf...
