Problems solved by technology

In this type of platform, due to the use of large-section reinforced concrete bridges or steel beams, a large part of the bearing capacity of the beam body is used to bear its own weight, which greatly reduces the efficiency of the structure or materials.

Example Embodiment

[0024] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1a to Figure 1d As shown, the cable-rail elevated of the present invention has no common bridge platform, and the cable-rail elevated is composed of a lower support system 1 and an upper cable-rail platform 2 . The lower support system is composed of a plurality of supports made of steel structures or reinforced concrete arranged at intervals in the longitudinal direction. The cable-rail platform 2 is a traffic platform composed of an upper-layer rail 22 and a lower-layer prestressed chord cable 21. The track and the chord cable are connected by a number of vertical support rods 23 to realize the pre-camber of the cable-rail platform, and are supported by a number of lateral supports. Rods 24 connect the two side cables to the track. The main body of the entire cable-rail elevated is composed of several span units in the l...

Abstract

The invention relates to an overhead cable track and a special track traveling crane thereof, belonging to the transportation technical field. The overhead cable track consists of a lower support system and an upper cable track platform, wherein, the lower support system is fixed on a ground base and the cable track platform is overhung; the cable track platform is a traffic platform composed of an upper track and a lower pre-stressed chord cable; and the track is connected with the chord cable through a plurality of vertical support rods, the whole overhead main body is longitudinally composed of a plurality of span units, and the head and the tail of the pre-stressed chord cable are anchored on the ground by an anchor. The invention further discloses a special track traveling crane which travels on the overhead chord cable, wherein, the track traveling crane is provided with a special wheel disk. In the invention, a cable structure is adopted for supporting transport load, thus the cable structural self-weight can be almost ignored compared with the existing bridge structure, which greatly saves steel and even requires no any concrete; and the track traveling crane can reach thespeed of about 300km/h of a wheel-track train, thus being an efficient, energy-saving and environmental-friendly transportation mode.

Description

technical field [0001] The invention relates to an elevated structure constructed by a cable aerial track platform and a special track vehicle for walking on the track platform, belonging to the technical field of transportation. Background technique [0002] According to the location of the transportation platform, the current vehicle transportation methods can be divided into two types: ground and overhead. The overhead forms include viaducts and rail transit. Existing overhead elevated or rail transit basically uses bridges as the transportation platform. Whether it is the lower platform (such as Shanghai light rail) or the suspended upper stress platform in rail transit (Chongqing light rail), almost all consider using beams as the stress members, which are supported by the lower members such as piers and transmit the load to the foundation. In this type of platform, due to the use of large-section reinforced concrete bridges or steel beams, a large part of the bearing...
