High bridge anti-falling device

Abstract

The invention relates to the technical field of safety equipment, and aims to build a trigger type high bridge anti-falling device which can trigger a mechanism when an individual falls from a bridge, quickly control an acting person and take rescue measures to eliminate safety accidents. The anti-falling device is composed of steel frame structures arranged on the outer side of the bridge side by side, the steel distance of each steel frame structure is 5 meters, the steel frame structures are fixed below handrails, a square with the side length being 5 meters is defined by T-shaped steel and a bridge body, rescue ropes are wound on steel frames through a plurality of sections of soft copper wires, an anti-falling net is stretched, and the steel frame frames are paved with the anti-falling net. When a falling person hits the net, the soft copper wire can be stretched open under the action of gravity, the falling person can fall down when pulling the anti-falling net, the rescue rope can be tightened, and the person can be wrapped in the anti-falling net and hung on a bridge handrail by the rescue rope. And then the rescue rope is pulled up by a vehicle-mounted winch to finish rescue. The method has the advantages that 1, the concealment is good; 2, rescue is convenient; and 3, the maintenance is convenient.

Description

Technical Field

[0001] The invention relates to the technical field of safety equipment and is a device used for preventing a high bridge from falling. Background Art

[0002] There are three common methods for high bridge anti-fall devices in the world. One is to install steel mesh under the bridge, such as the Golden Gate Bridge in the United States; the second is to raise the fence, such as the Nanjing Yangtze River Bridge; the third is to install rollers on the railings, such as the Mapo Bridge in Seoul, South Korea. These measures still have loopholes. The bridge device of the present invention can truly eliminate the hidden danger of falling. Summary of the invention

[0003] The purpose of the present invention is to build a trigger-type bridge anti-falling device, which can trigger a mechanism when an individual falls from the bridge, quickly control the faller, and take rescue measures to prevent safety accidents.

[0004] To achieve the above object, the present invention adopts the following technical solution: The anti-fall device is composed of a steel frame structure arranged side by side on the outside of the bridge (such as Figure 1 ). Scientific design of single steel frame structure (such as Figure 2 ), T-shaped steels are fixed under the railings at intervals of 5 meters. The T-shaped steels and the bridge body form a square with a side length of five meters. Several iron rings are welded inside each frame; the rescue rope passes through the edge of the anti-fall net, and the rope head is fixed on the bridge railing; use several sections of soft copper wire to wrap the rescue rope around the steel frame, stretch the anti-fall net, and the anti-fall net will cover the entire steel frame.

[0005] The soft copper wire is moderately soft. Be careful not to tie a knot (such as Figure 3 The force that the soft copper wire can withstand is required to be slightly greater than the weight of the rescue rope and the anti-fall net. When the faller hits the net, the soft copper wire will stretch under the action of gravity, and the faller will pull the anti-fall net and fall down. The rescue rope will tighten, and the faller will be wrapped in the anti-fall net and hung on the bridge railing by the rescue rope (such as Figure 4 ). Then use the vehicle-mounted winch to pull up the rescue rope to complete the rescue.

[0006] In order to prevent the faller from falling onto the steel frame and getting injured or landing close to the edge, a smooth transparent PC plate and a buffer rubber strip should be installed on the steel frame to ensure a safe rescue effect.

[0007] The steel frame structure is five meters apart and arranged on the outside of the bridge to cover the entire bridge. The bridge is protected without blind spots, eliminating safety accidents. This device is suitable for high bridges above 20 meters, and does not need to be configured for low bridges. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of the overall assembly of the device. Figure 2 It is a single steel frame design drawing. Figure 3 This is a detailed enlargement. Figure 4 This is a diagram showing the effect of the device starting up.

[0009] Features and Benefits 1. Good concealment. There is nothing abnormal on the bridge deck. All equipment is installed under the bridge, which fully reflects the beauty and neatness of the bridge. 2. Convenient rescue: rescuers can just pull the anti-fall net onto the bridge. 3. Convenient maintenance, which can be completed with a small lift truck.

Claims

1. A trigger-type high bridge anti-fall device, characterized in that: It consists of two parts: a protection system and a rescue system installed under the bridge.

2. The protection system is characterized by: The anti-fall net installed on the frame will automatically trigger the hunting function after being hit, and control the falling person in a hanging manner, thereby protecting and controlling the falling person and hanging him under the bridge waiting for rescue.

3. The rescue system is characterized in that a fallen person can be pulled onto the bridge deck using a vehicle-mounted winch.
