Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, and more particularly to a combined cable bridge with high bearing strength. Background Art

[0002] A cable tray is a metal structure system used to lay and protect power cables. It consists of brackets, supports, and installation accessories. It can be erected independently or laid on various building structures and pipe corridors. At present, cable trays are widely used due to their ability to lay and protect power cables. Existing cable trays generally adopt an integral structure and make the trays larger in size, which makes the cable trays very inconvenient during transportation and installation. This not only increases the workload of the staff, but also poses certain safety hazards. In addition, in order to facilitate the transportation of cable trays, cable trays are generally thin, which makes the bearing strength of cable trays mostly not high, seriously affecting the laying of cable trays and the protection of power cables.

[0003] In response to the above problems, in order to facilitate the transportation of cable trays, cable trays are generally thin, which makes the bearing strength of cable trays mostly not high, seriously affecting the laying of cable trays and the protection of power cables. As for the technical problem, after a lot of searches, a patent application number 202323015399.4 was found, which is a combined cable tray with high bearing strength. It belongs to the field of cable trays and includes a side support assembly. There are two side support assemblies, and a bottom support assembly is provided in the middle of the two side support assemblies, wherein the upper surface of the side support assembly is covered with a cover assembly; this utility model realizes the function of combined use by providing side plates, cover plates, side plates and plug plates, and the disassembly and assembly speed is fast, which facilitates the transportation of cable trays. However, the technical solution provided by this patent has the following problems:

[0004] (1) The cable tray is formed by combining side plates, cover plates, side plates and plug plates. Although the disassembly and assembly speed is fast, the cable tray is still long. For transportation and installation, a longer cable tray requires more manpower and material resources, and is more susceptible to bumps and vibrations during transportation, increasing the risk of deformation and damage of the cable tray. Once damaged during transportation, the repair cost is high and may affect the progress of the project.

[0005] (2) Secondly, once a fault occurs, the entire long bridge needs to be checked, which is difficult and time-consuming, affecting the normal operation of the cable system. When part of the bridge is damaged and needs to be replaced, the disassembly and replacement process of the long bridge is complicated, and the operation of the entire cable system may need to be interrupted.

[0006] The utility model can adopt a segmented bridge frame for installation, which is faster and more convenient during transportation, installation and maintenance, and reduces the inconvenience and risk caused by excessive size during transportation and installation. Utility Model Content

[0007] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provide a combined cable tray with high bearing strength.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined cable tray with high bearing strength, comprising: a bottom plate, a top plate arranged above the bottom plate, the left and right ends of the bottom plate are respectively threadedly connected to a left plate and a right plate, the bottom plate, top plate, left plate and right plate are combined into this section of the cable tray, positioning holes are opened at equal distances above the outer sides of the left and right plates, the rear of the top plate is connected to two positioning holes on the front sides of the left and right plates, and connecting plates are fixedly installed on the front and back sides of the inner sides of the left and right plates.

[0009] A further preferred solution is that a plurality of jacks are provided at both left and right ends of the bottom plate, and a positioning rod is fixedly installed at the front end of the bottom plate.

[0010] A further preferred solution: several through holes are provided at both ends of the top plate, a fixing plate is provided on the right side of the top plate, and several screw rods are provided on the left end of the fixing plate. The screw rods are matched with the through holes and positioning holes. The screw rods pass through the positioning holes, through holes and positioning holes on the right plate in sequence and are threadedly connected to the left plate.

[0011] A further preferred solution is that insert plates are provided at the four corners of the bottom of the top plate.

[0012] A further preferred solution: several screw rods 2 are fixedly installed on the bottom of the inner side of the right side panel, and the screw rods 2 are matched with the socket 1 on the bottom panel. Several limiting holes are opened at the rear ends of the right side panel and the left side panel, and several screw rods 3 are fixedly installed at the front ends of the right side panel and the left side panel, and the screw rods 3 are matched with the limiting holes.

[0013] A further preferred solution is that slots are provided on the front and rear sides of the upper ends of the right and left panels, and the plug-in boards are embedded in the slots.

[0014] A further preferred solution is that a plurality of second insertion holes are provided at the bottom of the inner side surface of the left side plate, and the second screw rod passes through the first insertion hole and the second insertion hole in sequence and is threadedly connected to the left side plate.

[0015] Beneficial effects:

[0016] 1. By providing screw rod 3, limiting holes and connecting plates, when two sections of bridge frames are connected, screw rod 3 on one section of bridge frame can be accurately inserted into the limiting holes on the other section of bridge frame. This design provides a clear positioning point for the connection of the bridge frames. After screw rod 3 is inserted into the limiting holes, it is threadedly connected through connecting parts such as nuts, so that the side panels of the two sections of bridge frame can be tightly fixed together to prevent relative displacement during use. The connecting plate can provide additional support and connection points at the splicing of the two sections of bridge frame, further enhancing the overall structural stability of the bridge frame.

[0017] 2. By providing a top plate, screw rod 1, and positioning holes, screw rod 1 sequentially passes through the positioning hole on the right plate, the through hole on the top plate, and the positioning hole on the left plate, and then is threadedly connected to the left plate, thereby firmly connecting the top plate to the left and right side plates. This connection method provides stable support for the bridge in the vertical direction, preventing the top plate from being deformed or shifted due to the weight of the cable or external pressure. In addition, when connecting multiple sections of bridges, the top plate can fix the side plates on the two sections of the bridge. It not only connects the tops of the two sections of the bridge, but also provides vertical support for the side plates, ensuring that the side plates of the two sections of the bridge are aligned in the horizontal and vertical directions, making the connection tighter and more accurate.

[0018] 3. In summary, this type of combined cable tray with high bearing strength is equipped with structures such as a top plate, a left plate, a right plate, and a connecting plate. The top plate, the left plate, the right plate and the bottom plate together form a closed space, which provides a safe laying environment for cables. The various components are tightly combined together through threaded connections, plug-in slots and screw connections to form a stable overall structure. When connecting the two sections of the cable tray, the two sections of the cable tray are connected through the connecting plate and other components on the side plates, and the side plates on the two sections of the cable tray are fixed and restricted by the top plate, which further enhances the stability of the connection, so that the side plates of the two sections of the cable tray are effectively supported in the vertical direction to prevent the side plates from being deformed or shifted due to the weight of the cables or external pressure.

[0029] Working principle: When installing this section of the bridge, place the bottom plate 1 in the installation position, insert the right side plate 3 into the socket 101 of the bottom plate 1 through the screw 2 301, and then pass it through the socket 2 401 of the left side plate 4, and use nuts and other connectors to thread the screw 2 301 to the left side plate 4, then insert the plug-in plate 204 at the bottom of the top plate 2 into the slots 306 at the upper ends of the right side plate 3 and the left side plate 4 for preliminary fixation, and then pass the screw 1 203 on the fixing plate 202 through the positioning hole 302 on the right side plate 3, the through hole 201 on the top plate 2 and the positioning hole 302 on the left side plate 4 in turn, and then Then pass through the left side plate 4 and be threadedly connected with the left side plate 4 through the external connecting piece. When this section of the bridge is spliced ​​with another section of the bridge, the positioning rod 102 on the bottom plate 1 of the first section of the bridge is inserted into the bottom plate 1 of the second section of the bridge to achieve preliminary fixation. As the bridges approach each other, the screw rods 304 at the front ends of the right side plate 3 and the left side plate 4 of the second section of the bridge are inserted into the limiting holes 303 at the rear ends of the right side plate 3 and the left side plate 4 of the first section of the bridge, and are threadedly connected through connecting pieces such as nuts, and the connecting plates 305 are also threadedly connected through connecting pieces such as nuts and screws, thereby strengthening the connection between the side plates on the same side of the two sections of the bridge. The stability of the connection, when the right side plate 3 and the left side plate 4 are installed, the connection position of the screw rod 203 and the positioning hole 302 needs to be changed. First, the rear side of the fixed plate 202 is connected to the front side of the right side plate 3 and the left side plate 4 on the section of the bridge, and the screw rod 203 passes through the positioning holes 302 on the front side of the right side plate 3 and the left side plate 4. The front side of the fixed plate 202 is connected to the rear side of the right side plate 3 and the left side plate 4 on the other section of the bridge, and the remaining screw rods 203 pass through the positioning holes 302 on the rear side of the right side plate 3 and the left side plate 4 on the other section of the bridge, so that the top plate 2 is aligned with the left and right sides of the two sections of the bridge. The right side plate 3 is fixed and restricted to complete the connection installation between the bridge frames. The subsequent sections of the bridge frames can be spliced ​​in sequence in this way. For the first and last sections of the bridge frames, the top plate 2 only needs to be installed corresponding to the outermost positioning holes 302 to complete the edge sealing installation of the bridge frame. When maintenance is required, due to its modular design, the various components can be disassembled relatively easily. During the maintenance process, the relevant parts can be removed in a targeted manner according to the location of the specific problem, without having to carry out large-scale disassembly of the entire bridge frame, which provides convenience for maintenance work, reduces maintenance costs and difficulty, and improves maintenance efficiency and safety.
