Description

Technical Field

[0001] The utility model relates to a cable installation device, in particular to a shock-absorbing cable installation device. Background Art

[0002] An integrated pipe corridor is a method of laying urban pipelines, and cable corridors are one of them. They require low investment and are easy to maintain after construction. Therefore, the application of cable corridors is becoming increasingly widespread, and they have become an important carrier for laying pipelines such as electricity, communications, water supply and drainage, and gas. During an earthquake, the pipelines move horizontally back and forth with the brackets, and the pipelines are easily damaged. The electricity, gas, and water resources carried by the cable corridor are all important resources required for emergency rescue after an earthquake disaster. It is very necessary to improve the seismic performance of the cable corridor and protect the pipelines. The current method of laying pipelines in cable corridors is direct burial, using plastic brackets for support or concrete to encapsulate the pipelines. This rigid connection method does not take into account the seismic requirements of the pipelines.

[0003] Chinese utility model patent publication number CN214900104U, entitled "An Underground Power Line Protection Device," discloses an underground power line protection device comprising a protective tube having a second groove formed at its upper end, a damping spring fixedly mounted at the bottom of the second groove, a protective pad fixedly mounted at the upper end of the damping spring, a wire conduit disposed within the protective pad, a filling layer disposed within the inner wall of the wire conduit, and a cable disposed within the filling layer. Platforms are provided on both sides of the second groove, a protective cover slidably connected to the upper end of the platform, and a first groove formed at the bottom of the protective cover. This underground power line protection device utilizes a damping spring. When the device is subjected to external pressure, the protective cover moves downward, causing the first groove to contact the wire conduit, thereby causing the wire conduit to move downward, compressing the damping spring. The damping spring then dissipates the external pressure through the downward sliding of the protective pad and, under the action of the damping spring, eliminates the external pressure, thereby protecting the wire conduit and extending its service life. While this device can provide some protection against external pressure, it is complex in structure and difficult to maintain and repair if components become damaged. Utility Model Content

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0027] like Figure 1-4 As shown, a U-shaped damper shock-absorbing cable support includes a base plate 1, a U-shaped damper 2 installed on the base plate 1, a top plate 3 installed on the U-shaped damper 2, and a plate-shaped cable bracket 4 vertically installed on the top plate 3, wherein the cable bracket 4 is provided with a plurality of cable through holes 41.

[0028] The U-shaped damper 2 includes an upper connecting section 21, an upper transition section 22, an energy consuming section 23, a lower transition section 24, and a lower connecting section 25. The energy consuming section 23 is arc-shaped. The upper transition section 22 is located between the upper connecting section 21 and the upper end of the energy consuming section 23. The lower transition section 24 is located between the lower connecting section 25 and the lower end of the energy consuming section 23.

[0029] The longitudinal sections of the upper connecting section 21 and the lower connecting section 25 are larger than the cross section of the middle portion of the energy consuming section 23 . The longitudinal section of the upper transition section 22 gradually decreases from the upper connecting section 21 toward the energy consuming section 23 . The longitudinal section of the lower transition section 24 gradually decreases from the lower connecting section 25 toward the energy consuming section 23 .

[0030] The upper connecting section 21 and the lower connecting section 25 are both provided with a U-shaped damper mounting hole 26;

[0031] The top plate 3 is provided with a top plate mounting hole 31 corresponding to the U-shaped damper mounting hole 26;

[0032] The bottom plate 1 is provided with a bottom plate mounting hole 11 corresponding to the U-shaped damper mounting hole 26 .

[0033] The U-shaped dampers 2 are made of metal material and there are no less than two of them.

[0034] There are four U-shaped dampers 2, which are arranged in a matrix and installed on the base plate 1. The lower connecting section 25 is detachably connected to the base plate 1 by bolts, and the top plate 3 is detachably connected to the upper connecting section 21 by bolts.

[0035] The four U-shaped dampers 2 are arranged in two rows along the length direction of the cable, and the notches of the two U-shaped dampers 2 in each row are arranged to face each other.

[0036] The cable support 4 has a plurality of cable through holes 41 arranged in both the longitudinal and transverse directions.

[0037] The cable bracket 4 is made of metal, is integrally formed, prefabricated as a whole, transported to the site for hoisting, or is rigidly assembled, that is, the assembled connection parts must be rigidly connected; the size of the cable bracket 4, the number of cable through holes 41, and its structure are determined according to needs, can meet the stable installation of a large number of cables, and have a simple structure.

[0038] The bottom plate 1 and the top plate 3 are both made of steel.

[0039] The cable bracket 4 is welded to the top plate 3 .

[0040] The installation process of the present invention is as follows: the bottom plate 1 and the top plate 3 are prefabricated in the factory according to the required dimensions. During construction, the bottom plate 1 is first embedded in the cushion concrete or concrete pier; then, bolts are used to connect the U-shaped damper holes of the lower connecting section 25 of the four U-shaped dampers 2 with the bottom plate mounting holes of the bottom plate 1, and then bolts are used to connect the U-shaped damper holes of the upper connecting section 21 of the U-shaped damper 2 with the top plate mounting holes of the top plate 3, and the bottom of the cable bracket 4 is welded to the top plate 3.

[0041] During an earthquake, the cable and the ground experience horizontal relative displacement. The energy-absorbing section 23 of the U-shaped damper 2 undergoes reciprocating bending and torsional deformation, dissipating the seismic energy. Combined with the cable through-holes 41 of the cable support 4, the cable retaining mechanism effectively minimizes relative displacement between the cable and the ground, thereby reducing horizontal cable displacement and protecting the cable from damage. After an earthquake, a damaged U-shaped damper 2 can be easily replaced by removing the bolts.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
