Embodiment 1

[0045] like Figure 1-7 As shown in the figure, a bridge cable structure lighting lamp device described in this embodiment includes a cylindrical lampshade 3 and a lamp body assembly 10 respectively used to be connected to the cable structure 1, and the cylindrical lampshade 3 is sleeved on the cable Outside the structure 1 , the lamp body assembly 10 is located in the cylindrical lampshade 3 .

[0046] The lamp body assembly 10 includes a lamp body 4 and a clamp assembly 14 connected to the lamp body 4 . The clamp assembly 14 is used to connect to the outside of the cable structure 1 , and the clamp assembly 14 includes a clamp 2 and clamp fasteners 5, the lamp bodies 4 are plural, and at least two of the lamp bodies 4 are arranged at intervals.

[0047] The outer wall of the cylindrical lampshade 3 is provided with ventilation holes 11, which can increase the aerodynamic stability of the cable structure, suppress the occurrence of vibrations such as wind-rain vibration, vor...

Embodiment 2

[0065] like Figure 1-7 As shown, a bridge cable structure lighting lamp device described in this embodiment includes a cylindrical lampshade 3 and a lamp body assembly 10. The lamp body assembly 10 includes a clamp lamp and related connecting devices. The clamp lamp consists of a clamp 2. The lamp body 4 and the clamp fastener 5 are composed. Most of the existing lamps and lanterns install the lamp body support device on the cable structure first, and then install the lamp body on the support device, which easily destroys the stable circular section of the cable structure. The lamp device proposed by the patent of the present invention directly fixes the lamp body 4 on the cable structure 1, and then wraps the unstressed cylindrical lampshade 3 on the outside of the cable structure.

[0066] The clamp 2 is provided with a wire installation slot for fixing the wire 6 .

[0067] The light plate of the lamp body 4 is made of flexible material, such as a PC thin plate, the radi...

Embodiment 3

[0071] like Figure 8 As shown in the figure, the bridge cable structure lighting lamp device described in this embodiment is different from the embodiment 1 or 2 in that the outer wall of the cylindrical lampshade 3 is provided with ventilation holes 11 and holes for light transmission. The light-transmitting holes 22 , at least two of the light-transmitting holes 22 are arranged at intervals along the axial direction of the cylindrical lampshade 3 . Because the bridge cable structure lighting fixture needs better toughness and anti-destructive ability, if the tubular lampshade 3 is not made of light-transmitting material, such as aluminum alloy material, the tubular lampshade 3 can be used at the part where the lamp is installed. partially transparent.

Abstract

The invention relates to the technical field of bridge cable structures, in particular to a bridge cable structure brightening lamp device and a cable structure assembly.The bridge cable structure brightening lamp device comprises a barrel-shaped lampshade and a lamp body assembly which are used for being connected to a cable structure, the barrel-shaped lampshade is arranged on the outer side of the cable structure in a sleeving mode, and the lamp body assembly is located in the barrel-shaped lampshade. According to the lamp device for brightening the bridge cable structure, when the cable structure is detected and maintained in the later period, only part of the lampshade needs to be detached, the lamp body assembly does not need to be detached together, the weight of a detached object is effectively reduced, and due to the fact that the lamp body assembly does not need to be detached, a circuit does not need to be pulled, and detection and maintenance of the cable structure are more convenient. The tubular lampshade is arranged on the outer side of the cable structure in a sleeving mode, the lamp body assembly is arranged in the tubular lampshade, the section of the tubular lampshade is a circular section, and according to the classic galloping theory, galloping cannot happen to the cable structure after a lamp is installed, or the galloping probability and amplitude of the cable structure after the lamp is installed are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of bridge cable structures, in particular to a bridge cable structure lighting lighting device and a cable structure assembly. Background technique [0002] Cable structure is the main load-bearing component of cable-bearing bridges (such as cable-stayed bridges and suspension bridges), and the stability of its performance is related to the normal operation of the entire bridge. The bridge cable structure is a slender member with low damping and is prone to vibration under the action of wind. According to the different mechanisms of wind-induced vibration, it can be divided into vortex-induced vibration, wind-rain-induced vibration, dry cable galloping vibration, galloping vibration and wake-induced vibration. After decades of research, some progress has been made in the mechanism of various vibrations of stay cables and the corresponding suppression measures. [0003] However, in recent years, with the im...
