Embodiment Construction

[0032] Such as figure 1 The overhead rigid catenary cantilever support device for the tunnel shown includes a support base 1 installed on the tunnel wall, and a support frame 2 is movably connected to the support base 1. In this embodiment, a support frame 2 and a support base 1 are provided. There is an adjustment support 6, that is, the adjustment support 6 is installed on the support base 1, and the support frame 2 is movably connected on the adjustment support 6. Wherein the support base 1 is installed on the tunnel wall off-centre of the tunnel, and the support frame 2 is arranged obliquely along the tunnel vault, making full use of the space so as to be able to implement installation in a low-clearance tunnel, wherein the adjustment support 6 can realize the adjustment of the support frame 2 The angle of inclination is adjusted. If the design is accurate enough and no adjustment is required, the support frame 2 can be directly arranged on the support base 1, and the adju...

Abstract

The invention discloses a low clearance tunnel rigid overhead line system cantilever supporting device. The device comprises a supporting base (1) fixedly mounted on a tunnel wall, wherein the supporting base (1) is movably connected with a support frame (2); the support frame (2) is arranged slantly along a tunnel vault; the end of the support frame (2) is connected with an insulating part (3); the insulating part (3) is connected with an adjusting support (4); a suspension clamp (5) capable of moving on the adjusting support (4) for adjusting is arranged on the adjusting support (4). The support frame is slantly arranged along the tunnel vault, so that the whole set of device is arch-shaped, the mounting space of a low clearance tunnel can be met, the device also can reach or even be higher than the function of the conventional cantilever supporting device, the structure is simple, and the mounting technology is simplified.

Description

technical field [0001] The invention relates to the technical field of an overhead rigid catenary suspension system for urban rail transit, in particular to an overhead rigid catenary cantilever support device for a low clearance tunnel. Background technique [0002] In the overhead rigid catenary suspension system of urban rail transit, the cantilever support device is fixed on the tunnel wall to support the suspension clamp fixture. With the continuous development of urban rail transit, in order to save engineering costs, the clearance of tunnels has been continuously reduced, and the requirements for overhead rigid catenary suspension systems are getting higher and higher. At present, cantilever supports are suitable for larger clearances, which cannot meet overhead rigid catenary suspensions under low clearances. system installation, so it is imperative to design a cantilever support device for the overhead rigid catenary that meets the requirements of low-clearance tunn...
