Description

Technical Field

[0001] The utility model relates to the technical field of cable brackets, in particular to a horseshoe-shaped tunnel ring network cable bracket. Background Art

[0002] The ring network cable support is a device specially designed for installing and supporting power cables. Its main application occasions include urban underground integrated pipe corridors, tunnels and other infrastructure. In these places, the ring network cable support plays a vital role. It not only ensures the safety and stability of the cables, but also helps to maintain and manage the cable lines, ensuring the stability and reliability of power transmission.

[0003] In the construction of urban underground integrated pipe corridors or tunnels, the construction of ring network cable supports is an important link. However, in actual construction, the existing designs of ring network cable supports often have certain limitations. Usually, the design of these supports only considers the tunnel structure of a single radius, that is, it is assumed that the cross-section of the tunnel is a standard circle or a single arc.

[0004] However, in some special tunnel structures, such as horseshoe tunnels, the cross-section of the tunnel is not a simple single-radius arc, but a combination of two arcs of different radii. In this case, when the ring network cable bracket needs to be installed at the junction of two arcs of different radii, the traditional single-radius design of the ring network cable bracket will encounter difficulties. Since this design cannot perfectly fit the tunnel wall with two different radii, a gap may appear between the bracket and the tunnel wall during the installation process, which not only affects the stability of the bracket, but may also have a negative impact on the protection effect of the cable.

[0005] Therefore, in order to adapt to this complex tunnel structure, it is necessary to improve the existing ring network cable support so that it can better adapt to the special structure of the horseshoe-shaped tunnel. For those skilled in the art, designing a ring network cable support that can fit the tunnel wall at the junction of two arcs with different radii to meet the needs of later ring network cable construction has become a technical problem that needs to be solved urgently. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a horseshoe-shaped tunnel ring network cable support, which can be installed on the tunnel wall at the junction of two circular arcs with different radii.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1-2The utility model provides a horseshoe-shaped tunnel ring network cable support, which is mainly suitable for the tunnel wall at the intersection of two different radii of the horseshoe-shaped tunnel, so as to support and fix the ring network cable. The specific structure includes a first arc frame 1, a second arc frame 2, a connecting frame 4 and a plurality of cross arms 5. Among them: the first arc frame 1 is in the shape of an arc and has a certain radius. The first arc frame 1 is located at a radius intersection of the horseshoe-shaped tunnel; the second arc frame 2 is similar to the first arc frame 1 and is also in the shape of an arc, but the radius of the second arc frame 2 is different from that of the first arc frame 1, and the second arc frame 2 is located at another radius intersection of the horseshoe-shaped tunnel. The connecting frame 4 is a connecting component, and the two ends of the connecting frame 4 are respectively connected to the end of the first arc frame 1 and the end of the second arc frame 2, which plays the role of connecting the first arc frame 1 and the second arc frame 2 together. The cross arm 5 is arranged in the horizontal direction and is arranged at intervals along the vertical direction. The main function of the cross arm 5 is to tighten the ring network cable to ensure the stability and safety of the cable. One end of the multiple cross arms 5 is fixedly connected to the concave surface of the first arc-shaped frame 1 and the concave surface of the second arc-shaped frame 2, respectively. This design can ensure that the cross arms 5 are firmly attached to the tunnel wall, thereby providing stable support. The other ends of the multiple cross arms 5 extend in a direction away from the concave surface of the first arc-shaped frame 1 and the concave surface of the second arc-shaped frame 2. This design enables the cross arms 5 to better adapt to the shape of the tunnel and provide sufficient support space for the ring network cable.

[0026] When in use, the convex surfaces of the first arc frame 1 and the second arc frame 2 are respectively directed toward the tunnel wall, and are respectively used to fit and fix on the tunnel wall at the intersection of two radii, ensuring that the cross arm 5 extends in the horizontal direction, and then the first arc frame 1 and the second arc frame 2 are connected by the connecting frame 4, so that the ring network cable can be supported and fixed by the cross arm 5. In the utility model, the first arc frame 1 and the second arc frame 2 adopt different radii, which can realize the installation process of the ring network cable bracket on the tunnel wall at the intersection of two different radii of the horseshoe-shaped tunnel, and can better adapt to the special structure of the horseshoe-shaped tunnel.

[0027] Preferably, one end of the connecting skeleton 4 is fixedly connected to the end of one of the first arc-shaped skeleton 1 and the second arc-shaped skeleton 2, and the other end of the connecting skeleton 4 is detachably connected to the end of the other of the first arc-shaped skeleton 1 and the second arc-shaped skeleton 2. Specifically, the other of the first arc-shaped skeleton 1 and the second arc-shaped skeleton 2 is provided with a first through hole 3, and the other end of the connecting skeleton 4 is provided with a second through hole, and the first through hole 3 and the second through hole are detachably connected with bolts 6. Through the detachable connection of the bolts 6, the fixing and disassembly of the first arc-shaped skeleton 1 and the second arc-shaped skeleton 2 can be achieved.

[0028] Optionally, the first arc-shaped frame 1 and the second arc-shaped frame 2 are both provided with mounting holes 7 arranged in the radial direction, and the first arc-shaped frame 1 and the second arc-shaped frame 2 are fixed to the tunnel wall by installing expansion bolts 6 in the mounting holes 7. In a specific embodiment of the utility model, the first arc-shaped frame 1 and the second arc-shaped frame 2 are respectively provided with a mounting hole 7 due to length limitations, and a connecting frame 4 is provided to connect the first arc-shaped frame 1 and the second arc-shaped frame 2, which can not only effectively prevent the first arc-shaped frame 1 and the second arc-shaped frame 2 from rotating when used alone, but also greatly improve the stability of the ring network cable bracket.

[0029] Specifically, the materials of the first arc-shaped skeleton 1, the second arc-shaped skeleton 2 and the connecting skeleton 4 are the first angle steel, the second angle steel and the third angle steel. Mounting holes 7 are arranged on one end surface of the first angle steel and the second angle steel. The other end surfaces of the first angle steel and the second angle steel are respectively welded and fixed to one end of a plurality of cross arms 5. The upper end of the third angle steel is fixedly connected to the inner side wall of the lower end of the first angle steel, and the lower end of the third angle steel is detachably connected to the inner side wall of the upper end of the second angle steel by bolts 6.

[0030] Optionally, the first angle steel is located above the second angle steel, and the radius of the first angle steel is greater than the radius of the second angle steel. In a specific embodiment of the utility model, the radius of the first angle steel is 4900 mm, the arc length of the first angle steel is 453 mm, the diameter of the second angle steel is 900 mm, the arc length of the second angle steel is 247 mm, and three cross arms 5 are arranged at intervals in the vertical direction, and the spacing between the cross arms 5 is 260 mm.
