Embodiment approach

[0022] As an embodiment of the present invention, the pier body 11 is hinged to the base 1 through a hinge support; One end of the reel is rotatably connected with a reel 21, the reel 21 is driven by a deceleration motor, and the deceleration motor is connected to the power supply through the controller; the reel 21 is wound with a steel wire rope 22, and the other end of the steel wire rope 22 is connected to the pier body 11 near the bridge deck 13 connection; through the reel 21, the steel wire rope 22 is rewound, and then the pier body 11 is erected to further increase the installation efficiency of the viaduct; when the base 1 is installed in place, the deceleration motor is started by the controller, and the deceleration motor drives the reel 21 to rotate, and the reel 21 Tighten the wire rope 22 so that the pier body 11 is erected. When the pier body 11 is completely erected, the pier body 11 and the base 1 are fixedly connected by welding equipment to enhance the stabil...

Abstract

The invention belongs to the technical field of bridges, and particularly relates to a municipal emergency overpass. The municipal emergency overpass comprises two bases, pier bodies made of steel trusses are arranged at the tops of the bases, platforms are fixedly connected to the tops of the pier bodies, bridge decks are hinged at one sides of the platforms, oil cylinders are obliquely arrangedbelow the bridge decks, one ends of the oil cylinders are hinged to the bottoms of the bridge decks, the other ends of the oil cylinders are hinged to the upper parts of the pier bodies, the oil cylinders are connected with high-pressure oil pumps through valves and pipelines, when the bridge decks work, the bridge decks are folded after being contracted through the oil cylinders, so that the occupied area is reduced, one side, far away from the corresponding pier body, of one bridge deck on one side is provided with a group of clamping openings, the positions, corresponding to the clamping openings, of the side surface of the bridge deck on the other side are provided with a group of T-shaped clamping columns, and the two bridge decks are mutually locked through cooperation between the clamping columns and the clamping openings. According to the municipal emergency overpass, the oil cylinders push the bridge decks to slow rotate, then the clamping columns are clamped into the clampingopenings to enable the two bridge decks to be tightly connected, namely the bridge decks can be rapidly installed in place, the use of large-scale hoisting equipment is avoided, and the installationefficiency of the overpass is improved.

Description

technical field [0001] The invention belongs to the technical field of bridges, in particular to a municipal emergency viaduct. Background technique [0002] In order to alleviate traffic congestion on urban roads, a viaduct expressway around the city was built to divert long-distance cross-district passenger flow and logistics vehicles from the ground to reduce the traffic flow across the ground road in the city center. However, because the multiple ramps at the intersection of the viaduct and the ground road occupy land Large, the upper and lower entrances of the overpass are mostly built on the outskirts of the city, and most vehicles still have to enter the crowded ground lanes in the city for half a circle around the city. It can be used for vehicles and equipment to reach the destination quickly. Contents of the invention [0003] In order to make up for the deficiencies of the existing technology and solve the problem that there is no ground emergency fast track fo...
