Description

Technical Field

[0001] The present application relates to the technical field of cable trays, and in particular to a cable tray for rail transportation. Background Art

[0002] During the rail transit construction process, cables need to be laid for the convenience of control and management. At the same time, in order to improve the use efficiency, the cables are generally laid on the side walls of the track groove, which requires the use of a wiring rack to support and position the cables. However, the existing wiring racks are mostly flat-plate structures, with the sides directly fixed to the wall. This is not only costly, but most of the cables are stacked together, which not only affects the heat dissipation safety, but also is not conducive to subsequent maintenance and is difficult to find. It is also inconvenient to adjust the installation direction according to the installation position, and has poor adaptability, which needs to be improved.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN211183212U discloses a wiring rack for rail transportation. The patent sets an arc pressure plate and mounting holes so that the cables can be distributed at intervals, which is conducive to heat dissipation and convenient for horizontal installation. However, the installation and disassembly operations of the positioning block in the patent are relatively troublesome, affecting the operating efficiency. In addition, the above patent can be installed horizontally, but the direction of the cable is the same when installed horizontally and vertically. In the rail cable routing, it is not convenient to adjust the direction of the cable. Therefore, it is necessary to design a wiring rack for rail transportation. Utility Model Content

[0029] During operation, the cables pass through the wiring holes 4 of the main frame 1 and the auxiliary frame 2 to achieve the purpose of auxiliary wiring. When multiple cables need to be routed, the sleeve 7 can be driven to rotate through the cross column 8, and the sleeve 7 rotates and performs threaded movement with the screw 9. Since the screw 9 is fixedly connected to the connecting block 6 and the auxiliary frame 2 is slidably connected to the main frame 1, the auxiliary frame 2 can slide with the main frame 1 under the threaded movement of the screw 9 and the sleeve 7, so that the auxiliary frame 2 moves downward along the limit groove 3, which can achieve the purpose of increasing the wiring holes 4, facilitate the simultaneous installation of multi-end cables, and the operation is simple and fast, thereby improving the operating efficiency.

[0030] In some embodiments, see Figure 2-3 The upper surface of the fixed block 5 is provided with a mounting groove 10, the inner wall of the mounting groove 10 is rotatably connected with a rotating block 11, the upper surface of the rotating block 11 is fixedly connected with a column 12, the upper surface of the column 12 is fixedly connected with a mounting plate 13, the upper surface of the mounting plate 13 is provided with a through hole 14, the through hole 14 passes through the upper surface of the mounting plate 13 and extends to the lower surface of the mounting plate 13.

[0031] During operation, the mounting plate 13 is connected to the inner wall of the track by means of screws and other parts, so that the device as a whole can be fixed. Rotating the main frame 1 can drive the movement of the fixed block 5, so that the fixed block 5 can rotate with the rotating block 11, thereby achieving the purpose of adjusting the axial angle of the main frame 1 and the sub-frame 2.

[0032] In some embodiments, a movable frame 15 is slidably connected to both sides of the fixed block 5, one end of the movable frame 15 passes through both sides of the fixed block 5 and extends to the inner wall of the mounting groove 10, one end of the movable frame 15 is fixedly connected to a clamping block 16, and clamping grooves for the clamping block 16 are evenly opened on the outer surface of the rotating block 11.

[0038] Working process of this application:

[0039] During use, the cables pass through the wiring holes 4 of the main frame 1 and the auxiliary frame 2 to achieve the purpose of auxiliary wiring. When multiple cables need to be routed, the sleeve 7 can be driven to rotate through the cross column 8, and the sleeve 7 rotates and performs threaded movement with the screw 9. Since the screw 9 is fixedly connected to the connecting block 6 and the auxiliary frame 2 is slidably connected to the main frame 1, the auxiliary frame 2 can slide with the main frame 1 under the threaded movement of the screw 9 and the sleeve 7, so that the auxiliary frame 2 moves downward along the limiting groove 3. After the downward movement is completed, the wiring holes 4 on the auxiliary frame 2 correspond to the wiring holes 4 on the main frame 1, so as to achieve the purpose of increasing the wiring holes 4, which is convenient for the simultaneous installation of multiple-end cables. The operation is simple and quick, and the mounting plate 13 is connected to the track wall through the through hole 14 through screws and other components. The movable frame 15 is fixed to the wall, so that the overall position of the device is fixed. When the direction of the cable routing needs to be changed, the movable frame 15 is pulled outward. At this time, the movable frame 15 and the fixed block 5 are in sliding motion, and the meshing groove 18 of the cross plate 17 on the movable frame 15 is meshed with the meshing shaft 20, so that the two movable frames 15 are separated from each other and drive the clamping block 16 to break away from the restriction on the rotating block 11. At this time, the main frame 1 can be rotated to adjust the axial angle of the main frame 1 and the auxiliary frame 2. After adjustment, the movable frame 15 is released, and the two movable frames 15 and the two clamping blocks 16 are driven to reset under the action of the tension spring 21 to restrict the rotating block 11, thereby completing the axial angle adjustment of the main frame 1 and the auxiliary frame 2. The adjusted main frame 1 and the auxiliary frame 2 can facilitate the change of the direction of cable routing.
