Problems solved by technology

[0003] combine Figure 9 and Figure 10 , when laying cables overhead in the tunnel, a cable rack is often used. The cable rack includes two rods 1 connected to the top wall of the tunnel, and two connecting rods 11 are arranged between the rods 1 on both sides. The two ends of the connecting rod 11 are respectively connected to the rod bodies 1 on both sides. A plurality of cable racks are arranged along the length direction of the tunnel in the tunnel. When laying the cables, the cables are pulled so that the cables pass through the two connecting rods 11 of each cable rack. Between, but its disadvantage is that when the cable passes through multiple cable racks, it will cause a lot of friction between the cable and the cable rack, which will not only cause damage to the cable, but also cause the laying personnel to be unable to pull the cable go ahead

Embodiment 1

[0039] refer to figure 1 , is a subway station bridge cable laying device disclosed by the present invention, comprising two rod bodies 1 with one end connected to the top wall of the tunnel, two connecting rods 11 are arranged between the rod bodies 1 on both sides, and the two connecting rods 11 have two The ends are respectively connected to the rod bodies 1 on both sides, and the diameters of the rod body 1 and the connecting rod 11 are equal.

[0040] Such as figure 1 As shown, passing parts are provided between the two rod bodies 1 and between the connecting rods 11 on both sides to allow cables to pass through to reduce friction. The passing parts include two seat bodies 2 arranged parallel to each other. A rotating roller 21 is rotatably connected between the bodies 2 . When the cables are laid, the cables are passed on the rotating rollers 21 on each cable rack, which reduces the friction between the cables and the cable racks, thereby preventing the cables from b...

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 mainly lies in: the combination image 3 with Figure 4 , the fixing member includes an elastic elastic plate 4 that is relatively arranged on the surface of the seat body 2 away from the rotating roller 21. In this embodiment, the elastic plate 4 can be set as a thin plate made of metal material; the elastic plate 4 is in the shape of a rod body 1 or the arc-shaped setting that the outer wall of connecting rod 11 fits.

[0047] combine image 3 with Figure 4 The end of the elastic plate 4 away from the seat body 2 is provided with a second fixed plate 41 extending in a direction away from the seat body 2, the second fixed plates 41 on both sides are arranged parallel to each other, and the edge of the second fixed plate 41 away from the elastic plate 4 faces A waist-shaped hole 42 is defined in the second fixing plate 41 .

[0048] combine Figure 4 with Figure 5 , the fixing member includes abutting plate...

Embodiment 3

[0055] The difference between this embodiment and Embodiment 1 mainly lies in: the combination Image 6 with Figure 7 , the fixing member includes a locking plate 5 arranged on the surface of the seat body 2 away from the rotating roller 21, the surface of the seat body 2 away from the rotating roller 21 is hingedly provided with a hinged plate 51 that rotates toward the locking plate 5, the locking plate 5 and the hinged plate 51 They are all arranged in an arc shape that fits the outer wall of the rod body 1 or the connecting rod 11, the locking plate 5 is provided with a stationary plate 52 on the edge away from the base body 2, and the hinge plate 51 is provided with a stationary plate 52 parallel to the edge of the base body 2. The mobile plate 53.

[0056] combine Image 6 with Figure 7 , the movable plate 53 is provided with a fixed rod 54 perpendicular to the movable plate 53, and the stationary plate 52 is provided with a through hole 56 for the fixed rod 54 to p...

Abstract

The invention relates to a metro station bridge cable laying device, and belongs to the technical field of cable laying auxiliary equipment. The metro station bridge cable laying device comprises tworod bodies, wherein the two ends of the rod bodies are connected to the top wall of a tunnel; two connecting rods are arranged between the rod bodies on the two sides; the two ends of the two connecting rods are connected to the rod bodies on the two sides respectively, wherein the diameter of the rod body and the diameter of the connecting rod are equal; a passing part for allowing a cable to pass through to reduce friction force is arranged between the two rod bodies and between the connecting rods on the two sides separately; the passing part comprises two seat bodies which are arranged inparallel, and a rotating roller is rotationally connected between the two seat bodies; fixing parts used for fixing the passing part to the space between the two rod bodies or between the connecting rods on the two sides are arranged on the seat bodies; when the cable is pulled by a laying person, the cable can drive the rotating roller to rotate, so that the friction force between the cable and acable frame is reduced when the cable is pulled, damage caused by friction of the cable is avoided, and the cable can be conveniently laid.

Description

technical field [0001] The invention relates to the technical field of cable laying auxiliary equipment, in particular to a bridge cable laying device for subway stations. Background technique [0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable route. According to the application occasion, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Intra-city distribution cables can be laid overhead or on walls. With the development of modern urban construction, they will gradually be replaced by pipeline laying. A cable tunnel is a corridor or tunnel structure used to accommodate a large number of cables laid on cable supports. In addition to allowing the tunnel to better protect the cables, the cable tunnel can also make it easy for people to inspect and repair the cables. [0003] combine Figure 9 and Figure 10 , when laying cab...
