An anti-fall protection device for a bridge

Abstract

The invention relates to the technical field of bridges, and discloses an anti-falling river protection device for bridges, which includes a fixing part, a protection part and a control mechanism, the fixing part is fixed on the bottom surface of the outer edge of the bridge, and both the protection part and the control mechanism are fixedly installed on the fixing part Above, the control mechanism includes an insulating cylinder and a cable. The insulating cylinder is fixedly connected to the left side of the fixed frame. An electromagnet is fixedly installed in the insulating cylinder. A cable is fixedly installed at the front and rear ends of the insulating cylinder respectively. The cable and the electromagnetic inside the insulating cylinder The two cables are connected by iron, and the ends of the two cables far away from the insulating cylinder are fixedly installed with aviation connectors. Through the setting of the protective parts, the protective parts are fixed by bridges, and the receiving plate adopts a telescopic structure to share the stress point of the heavy load. On the bridge, it has enough support to ensure the stability of the vehicle, and compared with the existing mesh structure, the steel bearing mechanism has stronger impact resistance and strength, which is enough to withstand the impact of the vehicle falling. impact.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an anti-falling river protection device for bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A large number of protective measures for bridges use guardrails to prevent vehicles from falling into the river. However, when vehicles go straight to the guardrails, the huge impact will be The guardrail was broken directly, causing the vehicle to fall into the river, and it was difficult for the passengers in the vehicle to escape after the vehicle fell into the river. [0003] The existing patent No. CN108221641A proposes a bridge anti-fall device, which has the advantage of opening the protective net through the rotating mechanism when an accident occurs, but when the protective net is stressed, a large number of force points are shared on the rotating mechanism.

[0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A large number of protective measures for bridges use guardrails to prevent vehicles from falling into the river.

[0003] The existing patent No. CN108221641A proposes a bridge anti-fall device, which has the advantage of opening the protective net through the rotating mechanism when an accident occurs, but when the protective net is stressed, a large number of force points are shared on the rotating mechanism. When it is heavy, the possibility of fracture of the rotating mechanism is extremely high, and the device uses a sensor as the trigger mechanism, but there is not only a lot of flying dust on the bridge, but also vibration and other phenomena, and the sensor corresponds to the position, cleanliness and accuracy. The requirements are very high, and the sensor detection error is prone to occur, which makes the device unable to start normally.
