River falling prevention protection device for bridge

Abstract

The invention relates to the technical field of bridges, and discloses a river falling prevention protection device for a bridge. The device comprises a fixing part, a protection part and a control mechanism, the fixing part is fixed to the bottom face of the bridge outer edge. The protection part and the control mechanism are both fixedly installed on the fixing part. The control mechanism comprises an insulating cylinder and a cable; the insulating cylinder is fixedly connected to the left side of the fixed frame; an electromagnet is fixedly arranged in the insulating cylinder; the front endand the rear end of the insulating cylinder are each fixedly provided with a cable. The cable is connected with the electromagnet in the insulating cylinder; the ends, away from the insulating cylinder, of the two cables are fixedly provided with aviation connectors. with arrangement of the protection part, the bridge is used for fixing the protection part; the bearing plate is of a telescopic structure, stress points for bearing heavy objects are shared on the bridge, enough supporting force is achieved, the stability of vehicle placement is guaranteed, and compared with an existing net-shaped bearing structure, the tempered bearing mechanism has higher impact resistance and strength and is sufficient to bear the impact force of vehicle falling.

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.

[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.
