Embodiment 1

[0025] like Figure 1-3 As shown, the anti-falling device provided on the bridge provided by this embodiment includes guardrails 30 arranged on both sides of the bridge 10, and several anti-falling devices 40 are arranged inside the guardrails 30, and the anti-falling devices 40 are circular Or a square structure, the anti-dropping devices 40 are arranged in rows and columns, and are fixed on the backboard of the guardrail 30. Each anti-falling device 40 includes a pressure plate 44 that is airtightly and fixedly connected to each other, a detonating shell 48 and an interior full of The explosive storehouse 42 of high explosive 41, in order to guarantee that its sealing can waterproof, also can reduce weight and is convenient to install and transport, pressure plate 44, detonation shell 48 and explosive storehouse 42 are all selected hard plastics to make, and the center of press plate 44 The position is provided with firing pin chamber 47, is provided with the striker 46 that...

Embodiment 2

[0031] This embodiment has been improved on the basis of Embodiment 1, and other structures are the same, and the difference is:

[0032] like figure 1 As shown, in this embodiment, a rope net 20 is provided on the outside of the guardrail 30. The rope net 20 is a fishing net structure made of steel wire ropes of different thicknesses intersected with each other. The structure of the state, the cylindrical core material is made of hard plastic, when the anti-falling device 40 is in use or fails, when the vehicle and personnel to fall are not stopped, the core material in the middle of the rope net 20 will be broken by the falling vehicle , forming a number of fragments, and at the same time, the compressed steel wire rope net will be knocked open, and then the falling vehicle and personnel will be caught in the net, which is used to save the property loss of the vehicle and save the life of the personnel.

Abstract

The invention belongs to the technical field of bridges, and particularly relates to an anti-falling device arranged on a bridge. The anti-falling device arranged on the bridge comprises guardrails arranged on the two sides of the bridge. A plurality of anti-falling devices are arranged on the inner sides of the guardrails; and each anti-falling device comprises a pressing disc, a detonating shelland an explosive bin filled with high explosive, all of which are fixedly connected in a sealed mode. The pressing disc is provided with a firing pin bin, a firing pin is arranged in the firing pin bin, a disc spring supporting the pressing disc is arranged in the detonation shell, a detonator used for detonating the high explosive is arranged on the lower side of the firing pin, a detonator baseis arranged on the lower side of the detonator, a clamping head is arranged on the outer side of the detonator base and inserted into an external hanging base groove, and the external hanging base groove is fixedly formed in a back plate. In the invention, vehicles can be prevented from falling into the bridge or a river, damage to the vehicles and personnel is reduced, safety coefficients of thevehicles and personnel are improved, and daily maintenance after installation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of bridges and roads, and in particular relates to an anti-falling device arranged on a bridge. Background technique [0002] Bridges (10) are now used, such as figure 1 As shown, guardrails (30) are generally provided on both sides of the bridge body road surface (60) of the bridge (10), and isolation piers (50) are arranged in the middle of the bridge body road surface (60), and the isolation piers (50) connect the bridge The body road surface (60) is divided into traffic lanes in two directions, left and right. During the use of the bridge, it is often hit by a moving vehicle, which may cause damage and injury to the vehicle and personnel, and may cause a bridge or river fall in a severe case, and may also cause varying degrees of damage to the bridge body. In serious cases, it may cause blockage of the entire road or leave hidden dangers to driving safety. Contents of the invention [0003] In order...
