Mounting vehicle for construction of peripheral equipment of box beam under bridge

Abstract

The invention discloses an installing vehicle for equipment construction outside of box beam under great bridge. It is suspension structure, comprising upper vehicle and lower vehicle suspended on the lower end of upper vehicle. Upper vehicle comprises a walking system, a main girder and an auxiliary girder connected with the walking system, on which two ends of main girder are fixed. Lower vehicle comprises big cover, platform, outer frame and sliding plate. Sliding plate and platform are located by location device. Top bracing is fixed on said big cover and platform is suspended on the lower location of big cover by connector connected to outer frame and big cover. Elevator device is set between platform and big cover and upper and lower vehicles are hinged. As upper vehicle set on the bridge surface drives the lower vehicle under the bridge surface the invention can realize assembly for various equipment of great bridge box beam and is provided with simple structure, convenient operation and low cost so on. It solves the difficult problem that suspension working is done in sea.

Description

technical field [0001] The present invention relates to a kind of installation equipment, specifically a kind of installation vehicle that is convenient for construction personnel to carry out equipment construction on the outside of the box girder under the bridge deck, such as the installation and detection of various equipment such as corbels and electrical pipes at the box girder of the bridge. and maintenance. Background technique [0002] For the offshore bridge, the installation of the outer corbels of the box girder under the cast-in-place tamping girder deck, the installation of the maintenance platform and the steel corbels of the transformer platform, and the inspection of the reserved holes of the corbels above all require special equipment, which makes the construction Personnel can easily reach the construction site for installation and testing. According to the structural characteristics of the bridge, construction work can be carried out on the outside of th...

Problems solved by technology

According to the structural characteristics of the bridge, construction work can be carried out on the outside of the box girder of the bridge and in the gap under the upper and lower bridge wing plates. The traditional method: one is to build a full house of scaffolding, which can ensure the safety of construction workers, but due to the Below the box beams is the surging sea, so this method cannot be adopted. If suspended scaffolding is used, the gap between the upper and lower bridges is 1.5m, and the opening distance between the box beams is 9-10.5m, which cannot be guaranteed in terms of safety and stability. , so the construction measures of scaffolding cannot meet the requirements of measurement and installation on the bridge; the second is to use an upside-down working platform for measurement and installation construction. After investigation, this method can meet the requirements of safety and measurement and installation of steel corbels, but The biggest problem with this method is that the weight of each shelf is not less than 2t, and the displacement of the bulky shelf must be coordinated by a crane, which cannot meet the economic cost. Moreover, the shelf is divided into upper and lower parts, and the middle connecting part passes through a 1.5m gap. Therefore, the amount of movement in the vertical direction is very small, and it is basically impossible to adopt this method on the sea and on the island. At the same time, the construction progress cannot meet the requirements
