Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electric power engineering and building electromechanical installation, and in particular to an assembly-adjustable cable bridge and a use method thereof. Background Art
[0002] Cable bridges are divided into trough-type, tray-type, ladder-type, grid-type and other structures, and are composed of brackets, supports and installation accessories. The bridge in the building can be erected independently or laid on various buildings (structures) and pipe corridor supports. It should embody the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open air outside the building after galvanizing. For example, the publication number is CN118074033A, and the invention name is an adjustable cable bridge that is easy to lay. By adjusting the angle between the connecting platforms on both sides, the bridge bodies on both sides are adjusted in the vertical plane. Then, the big arm is controlled to rotate on the bridge body, so that the big arm drives the small arm and the connecting platform to rotate with each other, and the small arm is adaptively deflected on the connecting platform to change the position of the small arm on the connecting platform, so that the bridge bodies on both sides are adjusted in the horizontal plane. Therefore, the cable bridge changes the angle between the vertical plane and the horizontal plane to adapt to the shape requirements of the installation position. Existing cable trays have the following problems during installation: inconvenient adjustment. Traditional cable tray support brackets are mostly fixed, which makes it difficult to adapt to the spacing and height adjustment requirements of different installation environments. On-site cutting and welding are required, which has low construction efficiency and is easy to damage the anti-corrosion layer; insufficient seismic performance: under the action of earthquakes, the rigid connection between the cable tray and the bracket is prone to breakage, causing damage to the cables; installation accuracy relies on on-site measurements: bracket positioning requires multiple layouts, and accumulated errors can easily lead to misalignment of the cable tray splicing.
[0003] Therefore, there is an urgent need for a cable tray structure that integrates adjustable support, seismic buffering and modular assembly. Summary of the Invention

[0030] The technical solution of the present invention will be further described in detail below with reference to the embodiments and drawings.
[0031] Example 1
[0032] See also Figure 1-4 The present invention provides an assembly-adjustable cable tray: it includes a tray shell 1, and a wire groove 6 is provided on the upper surface of the tray shell 1; two grooves that pass through the left and right sides and are parallel in the upper and lower positions are provided in the tray shell 1, the first placement groove 7 and the second placement groove 8; the tray also includes an installation part, and the installation part includes a placement tray 2 and a fixed tray 4. The placement tray 2 and the fixed tray 4 are integrally formed and are stepped, wherein the cross-section of the end of the placement tray 2 is adapted to the shape of the first placement groove 7, and the cross-section of the end of the fixed tray 4 is adapted to the shape of the second placement groove 8; during installation, the end of the placement tray 2 is inserted into the first placement groove 7 on either side of the tray shell 1; the end of the fixed tray 4 is inserted into the second placement groove 8 on the other side of the tray shell 1, and the placement tray 2 and the fixed tray 4 are fixed to the tray shell 1 by fixing parts. Specifically, the end of the placement bridge 2 passes through the first placement slot 7 at one end of the bridge shell 1 and is movably set at the other end of the bridge shell 1, and the end of the fixed bridge 4 passes through the second placement slot 6 at the other end of the bridge shell 1 and is movably set at one end of the bridge shell 1. The insertion directions of the placement bridge 2 and the fixed bridge 4 are opposite, and the insertion positions are staggered, thereby completing the installation of the placement bridge 2, the fixed bridge 4 and the bridge shell 1.
[0033] In some preferred embodiments, in order to improve the accuracy of the relative positions of the placed bridge 2 and the fixed bridge 4, first fixing holes 3 are provided on both sides of the placed bridge 2, one end of the placed bridge 2 is connected to the fixed bridge 4, and second fixing holes 5 are provided on both sides of the fixed bridge 4. The number and spacing of the first fixing holes 3 and the second fixing holes 5 are equal. When the placed bridge 2 passes through the bridge shell 7 through the first placement groove 7; the fixed bridge 4 passes through the bridge shell 1 through the second placement groove 8, the position is determined by aligning the first fixing hole 3 and the second fixing hole 5. Furthermore, the fixing parts can fix the positions of the placed bridge 1 and the fixed bridge 4 by passing through the first fixing hole 3 and the second fixing hole 5.
[0034] It should be noted that in order to improve the structural stability of the installation portion, the placement bridge 2 and the fixing bridge 4 are integrally formed, and the placement bridge 2 and the fixing bridge 4 are in a stepped structure.
[0035] The connection method between the bridge frame shell 1 and the placement bridge frame 2 and the fixed bridge frame 4 is: second wire holes 14 are set on both sides of the wire groove 6, and the second wire holes 14 pass through the left and right sides of the bridge frame shell 1 and the first fixing hole 3 and the second fixing hole 5.

[0036] In some embodiments, it is also necessary to provide fixed blocks 9 on both sides of the bridge frame shell 1, and a first thread hole 10 is provided at the top of the fixed block 9. The first thread hole 10 is a hole that passes through from top to bottom, and a screw rod 11 is movably provided inside the first thread hole 10. The screw rod 11 is movably provided at the bottom of the fixed block 9 through the first thread hole 10, wherein a nut 12 is movably sleeved on the outer edge of the lower part of the screw rod 11, and a damper 13 is fixedly provided at the top of the screw rod 11, and the top of the damper 13 is provided on the main keel of the ceiling.
[0037] When in use, insert the end of the placement bridge 2 into the first placement slot 7 at either end of the bridge housing 1, pass through the bridge housing 1 to reach the other end of the bridge housing 1; adjust the first fixing hole 3 according to the required length, and align the position of the first fixing hole 3 with the second wire hole 14; insert the end of the fixed bridge 4 into the second placement slot 8 at the other end of the bridge housing 1, pass through the bridge housing 1 to reach one end of the bridge housing 1;

[0039] The screw rod 11 and the damper 13 at the top are fixedly connected to the installation position by bolts 15, thereby completing the fixing and erection of the bridge frame 2.
[0040] The method further secures the bridge housing in the installation position by rotating the screw rod, engaging the fixing block and nut at the bottom, and passing the fixing bridge through the bridge housing and securing it with bolts. This completes the securing and installation of the placement bridge 2, ensuring stability and ease of adjustment. Furthermore, all components are prefabricated in the factory, requiring only bolt connections on site. This increases installation efficiency by 60%, and allows for repeated assembly and disassembly. The damper 13 reduces vibration transmission by 50%.
