Interception cable type flexible anti-collision device for preventing ultrahigh vehicle from colliding with bridge and tunnel

Abstract

The invention relates to an intercepting cable type flexible anti-collision device for preventing an ultrahigh vehicle from colliding with a bridge and a tunnel. The device comprises a first support,a first rotating frame rotatably mounted on the first support, a second support, a second rotating frame rotatably mounted on the second support, and an intercepting cable connecting the first rotating frame and the second rotating frame. The first rotating frame comprises a first rotating pipe and a first transverse pipe fixedly connected with the first rotating pipe; the second rotating frame comprises a second rotating pipe and a second transverse pipe fixedly connected with the second rotating pipe; a first spring and a first sliding block are arranged in the first transverse pipe, one endof the first spring is fixedly connected with the first transverse pipe; a second spring and a second sliding block are arranged in the second transverse pipe, and one end of the second spring is fixedly connected with the second transverse pipe; and one end of the intercepting cable passes through the first spring and is fixedly connected with the first sliding block, and the other end of the intercepting cable passes through the second spring and is fixedly connected with the second sliding block. The invention can prevent the ultrahigh vehicle from colliding with the bridge and the tunneland reduce the damages to the vehicle and injuries to the people on the vehicle caused by the collision.

Description

technical field [0001] The invention relates to the technical field of an intercepting device for preventing super-high vehicles from colliding, in particular to an intercepting cable-type flexible anti-collision device for preventing super-high vehicles from colliding with bridges and tunnels. Background technique [0002] At present, the devices or methods to prevent super-high vehicles from colliding with bridges and tunnels mainly include the gantry method and the early warning system method. The frame is generally rigid, and it will encounter the problems of difficulty in replacement and high replacement cost after being hit once, and it will cause great damage to super-high vehicles, and even cause casualties; the main function of the early warning system method is The driver is reminded by physical measures such as sound and light, but the car cannot be stopped in time, and the bridge and tunnel facilities cannot be protected when the driver loses control of the vehic...

[0002] At present, the devices or methods to prevent super-high vehicles from colliding with bridges and tunnels mainly include the gantry method and the early warning system method. The frame is generally rigid, and it will encounter the problems of difficulty in replacement and high replacement cost after being hit once, and it will cause great damage to super-high vehicles, and even cause casualties; the main function of the early warning system method is The driver is reminded by physical measures such as sound and light, but the car cannot be stopped in time, and the bridge and tunnel facilities cannot be protected when the driver loses control of the vehicle, such as drunk driving, drug driving, and brake system failure. defect

[0003] In general, the existing devices for preventing super-high vehicles from colliding with bridges and tunnels have the following defects: First, the existing early warning system gantry is generally rigid, and it will be difficult and costly to replace after being hit once. Bigger problem Moreover, the rigid device will cause greater damage to super-high vehicles, and even more likely to cause casualties; second, the traditional early warning system gantry cannot combine the functions of early warning and protection of people on the vehicle; third, The traditional height-limiting gantry lacks or cannot perform well the function of reminding the driver that the vehicle is already super high; fourth, the elasticity of the traditional height-limiting gantry is not enough to restore its shape and function after being collided; fifth, The traditional height-limited gantry cannot be maintained quickly after being damaged, which is likely to cause traffic congestion: sixth, the traditional height-limited gantry cannot be reused after being damaged by impact, resulting in a waste of resources; seventh, the traditional early warning system gantry When the vehicle is out of control, it loses the function of the protection facility
