[0040] When in use, the traditional integrated cable tray is composed of the inclined slot plate 1, the tail slot plate 4, the first slot plate 5, the inclined cover plate 2, the first plate cover 8, and the tail plate cover 9. Using the above structure, the traditional integrated cable tray is divided into three assembly modules: the inclined slot plate 1, the tail slot plate 4 and the first slot plate 5. With the cooperation of the snap assembly, the second slot 10, the second card plate 11 and the first card plate 106, a complete cable tray is assembled. Therefore, the splicing length of the bridge member 3 on each layout line on the ceiling can be determined according to the spatial pre-arrangement of the indoor cables and the layout planning of other pipelines. , according to the size of the indoor space and the layout design of the cables on the ceiling, cable trays of different lengths can be assembled at will, avoiding the need to cut the integrated cable tray, avoiding the weight superposition caused by using a large number of screws to extend the length between the cable trays, and reducing the load of the cable tray hanging on the ceiling; the cable tray assembled using the above assembly method can provide convenience for later power maintenance and inspection, and can be disassembled and inspected locally on the cable tray without climbing into the ceiling or disassembling a large area of ​​cable tray, making it convenient for maintenance personnel to inspect any part of the cable tray;

[0041] At the same time, the inclined groove plate 1 can be used to divide the original integrated cable tray into multiple small parts with the horizontal length of the inclined groove plate 1 as an extension unit.

[0044] The second embodiment, as Figures 7 to 12As shown, the bridge member 3 has side connecting plates 301 symmetrically mounted on the left and right sides of the inclined groove plate 1, at least two right-angle plates 6 are bolted to the upper ends of the side connecting plates 301, and the side of the side connecting plate 301 away from the right-angle plate 6 is hinged with an adapter plate 302, and the side of the adapter plate 302 away from the side connecting plate 301 is hinged with a middle connecting plate 303; a plurality of screw holes are opened through the surface of the side connecting plate 301, and screws 305 are installed in the screw holes opened at the upper end of the side connecting plate 301, and a first disc 306 is fixedly connected to the middle part of one end of the side connecting plate 301 close to the adapter plate 302, and the left and right ends of the adapter plate 302 are fixedly connected to the second disc 309, and a shaft is inserted in the middle of the second disc 309. The second disc 309 and the shaft are used to cooperate with the first disc 306 for rotational installation; the front and rear ends of the side connecting plate 301 and the first disc 306 are symmetrically provided with arc-shaped slots 307, and the lower ends of the adapter plate 302 are symmetrically connected with arc-shaped plates 310 for limiting the installation of the first disc 306 and the side close to the adapter plate 302. The adapter plate 302 is provided with an arc-shaped clamping angle 311 at the position where the two ends of the adapter plate 302 are connected, and the arc-shaped clamping angle 311 is installed by the first disc 306 and the second disc 309 in combination with the arc-shaped slot 307, and the arc-shaped plate 310 can also be correspondingly engaged with the arc-shaped slot 307 when it rotates around the shaft following the second disc 309; the middle connecting plate The middle parts of the left and right sides of 303 are fixedly connected with the third disc 313, and the middle part of the lower end of the middle connecting plate 303 is fixedly connected with the second beam plate 312, the middle part of the lower end of the first disc 306 is fixedly connected with the first beam plate 308, and the middle parts of the lower ends of the second beam plate 312 and the first beam plate 308 are fixedly connected with a ring, and the inner side of the ring is inserted with a steel wire rope 12 to provide a stable support for the lower end of the bridge member 3; the third disc 313 is rotatably installed with the second disc 309 through the shaft, which can make the middle connecting plate 303 rotate around the shaft and the adapter plate 302, and the effective range of rotatable adjustment is at least 180 degrees, wherein the arc plate 310 can move the third disc 313 close to the adapter plate 302 The bottom of the arc-shaped edge is limited and clamped to improve the close connection between the adapter plate 302 and the middle connecting plate 303 structure, providing a certain support strength for the lower end side of the third disc 313. Similarly, the structural connection strength between the side connecting plate 301 and the adapter plate 302 also relies on the arc-shaped plate 310 to support the lower end side of the first disc 306. At the same time, it can also prevent the side connecting plates 301, the adapter plate 302 and the middle connecting plate 303 from being directly dislocated and falling due to external forces; among them, the side connecting plates 301 and the adapter plate 302 are symmetrically installed on the left and right sides of the middle connecting plate 303 with the middle connecting plate 303 as the center; the number of the middle connecting plate 303 is one, and the number of the side connecting plates 301 and the adapter plate 302 are both two.

[0045] When in use, by arranging the centers of the side connecting plates 301, the adapter plates 302, and the middle connecting plates 303 on the same horizontal straight line, the longitudinal support span of the cable tray by the bridge member 3 can be maximized. After fixing the side connecting plates 301 on any side, the bridge member 3 can be rotated to any angle around the shaft between the side connecting plates 301 and the adapter plates 302. This can not only reduce the longitudinal support span of the cable tray by the bridge member 3, but also reversely expand the lateral support area of ​​the bottom of the cable tray by the bridge member 3. At the same time, with the cooperation of the right-angle plates 6, the bridge member 3 can support and fix a cable tray with a slightly smaller width.

[0046] On the basis of the above operation, it is also possible to rotate the shaft between the adapter plate 302 and the middle connecting plate 303 to any angle to further reduce the longitudinal support span of the cable tray by the bridge member 3, further increase the effective support area of ​​the bridge member 3 and the bottom of the cable tray, and not only make the cable tray more stably installed on the ceiling, but also can, with the cooperation of the right-angle plate 6, provide fixed support for the cable tray with further reduced width; it can also provide fixed support for cable trays of different widths or heights;

[0047] At the same time, when the bridge member 3 supports two cable trays side by side, the above-mentioned rotation adjustment method can be used to adjust the lower end of one of the cable trays according to actual conditions, so as to reinforce the cable tray with excessive local load without adding unnecessary structural members. At the same time, the contact area between the bridge member 3 and the cable tray is expanded, providing more stable structural support and improving the safety and practicality of the bridge member 3.

[0048] The steel wire ropes 12 are passed through the first beam plates 308 on both sides and the second beam plate 312 in the middle, and the ends of the steel wire ropes 12 are fixed to the ceiling or wall, so as to assist the bridge member 3 in providing stable support to the bottom of the cable tray. The steel wire ropes 12 are used to connect each bridge member 3, and jointly provide auxiliary support to the individual chute plates 1 that are not directly fixed and supported by the bridge member 3.

[0049] At the same time, the bolt assembly between the bridge frame 3 and the inclined slot plate 1, the tail slot plate 4, and the first slot plate 5 ensures that the cable bridge will not fall apart or fall off easily even if it is disturbed by external forces, providing safety protection for indoor personnel.

[0050] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
