Description
Technical Field
The invention relates to a suspension system of a box-type track beam combined with an opening of a bottom plate of suspended monorail traffic, in particular to a suspension system formed by suspending the track beam below a bridge pier capping beam by using a guy cable, a base and a support in the suspended monorail traffic system.
Background
The german Eugen Langen invents suspended monorail traffic in 1893 and built 13.3km of suspended monorail in the city of the famous suspended car in the german luer Wu Pada city (Wupppertaler) in 1898-1901, which is the earliest in the world and is also the longest in history. Since then, suspended monorail railways of a certain mileage have been successively built by Duttmond, dulcet, qianlike city of Japan, kanesin county, etc. At present, a formally operated suspended type monorail transit line does not exist in China, and the Chongqing straddle type monorail transit line is a few monorail transit lines in China.
The existing civil structures such as the track beam and the bridge pier in the suspension type monorail traffic system are mostly in the form of steel structures, namely, steel box beams are adopted as the track beam, and the track beam is suspended in the air through steel upright posts. The steel track beam is simply supported on the corresponding two metal supports on the steel bridge pier bent cap through two metal support legs arranged outside the steel box beam, so that a steel box beam simple support stress system is formed. The stress system has the advantages that the stress buckling phenomenon is easy to occur due to the small thickness of the steel plate of the steel box beam, so that the load of a vehicle borne by the stress system is small, the shock resistance is unfavorable, the rail beam is easy to generate larger deformation, and the linear control of the rail beam is not facilitated; the metal structure is also prone to corrosion, affecting its durability.

The technical scheme adopted for solving the technical problems is as follows:
The utility model provides a suspension type monorail transit bottom plate opening combination box track roof beam suspension system, includes bottom plate opening combination box track roof beam (1), pier bent cap (2-2), concrete pier stud (3-1), concrete pier stud (3-2), pier foundation (4-1), pier foundation (4-2), fixed bolster (5-1), movable bolster (5-2), cable (6-1), cable (6-2), base (7-1), base (7-2), characterized by: installing a fixed support (5-1) on a first base (7-1), enabling a first inhaul cable (6-1) to sequentially penetrate through a first bridge pier bent cap (2-1) and the first base (7-1), tensioning and anchoring the first inhaul cable to the top surface of the first bridge pier bent cap (2-1), and hanging a combined box-shaped track beam (1) with an opening of a bottom plate below the first bridge pier bent cap (2-1); installing a movable support (5-2) on a second base (7-2), enabling a second inhaul cable (6-2) to sequentially penetrate through a second bridge pier bent cap (2-2) and the second base (7-2), tensioning and anchoring the second inhaul cable to the top surface of the second bridge pier bent cap (2-2), and hanging a bottom plate opening combined box-type track beam (1) below the second bridge pier bent cap (2-2); thereby forming a suspended floor opening combined box track beam suspension system.
The beneficial effects of the invention are as follows:
A box-shaped rail beam suspension system with a suspension type monorail traffic bottom plate opening combination replaces a steel box-shaped rail beam and a steel upright column in the existing steel structure, prevents the steel box-shaped rail beam from generating stress buckling phenomenon, increases the capacity of bearing the load of a vehicle and the shock resistance, reduces the deformation of the rail beam, is beneficial to the linear control of the rail beam, and improves the durability of the rail beam.
