Description

Technical Field

[0001] The utility model belongs to the technical field of cable bridges, and in particular relates to an anti-loosening combined cable bridge. Background Art

[0002] The technical background of the combined cable tray mainly stems from the unstable splicing of existing cable trays during ultra-long connections, and the problem of insufficient cable bearing capacity and pressure deformation. There are some challenges in the design and application of existing cable trays, especially when it is necessary to connect cables over longer distances. Traditional cable trays usually adopt a splicing method, but this splicing method is often unstable when connected over an ultra-long distance, which may cause deformation of the bridge or insufficient bearing capacity of the cables inside the bridge, and then cause pressure deformation problems. This pressure deformation will not only affect the appearance of the cable tray, but may also cause damage to the cables and affect their normal transmission function. In addition, the traditional cable tray splicing process usually requires a lot of manpower, is inefficient, and is prone to interference with other cables during construction. Therefore, the design of the combined cable tray should focus on solving these problems to improve the stability and bearing capacity of the cable tray, while improving construction efficiency, reducing the error rate during construction, and reducing the impact on the surrounding environment. Utility Model Content

[0003] In order to overcome the problem of unstable splicing when the existing cable tray is connected over a long distance, it is easy to cause the cable to be insufficiently loaded and deformed due to pressure.

[0004] The technical solution of the utility model is: a loose-proof combined cable bridge, including a three-way bridge assembly, and also including a high and low connecting bridge, a long straight bridge, a short straight bridge, a corner splicing block, a plane splicing block, and an external hanging connecting block; the high and low connecting bridges and the short straight bridge are respectively arranged on both sides of the three-way bridge assembly; and the long straight bridge is arranged at one end of the high and low connecting bridge.

[0005] Preferably, the three-way bridge assembly, high and low connecting bridges, long straight bridges and short straight bridges are independently hoisted and installed through the ceiling connecting fixing strips, which effectively shares the hoisting load-bearing force of each segmented bridge, and cooperates with the corner splicing blocks and the plane splicing blocks to achieve the convenience and stability of the segmented splicing of each bridge. Finally, the internal structure support plate is relied upon to realize the functions of internal space division and structural reinforcement of the lower and upper combined plates, effectively preventing the risk of compressive deformation of the internal structure of the lower and upper combined plates caused by load overload, and solving the problem of unstable splicing of existing cable bridges when connected in extra-long lengths, which easily causes insufficient load-bearing and pressure deformation of the cables.

[0006] Preferably, the three-way bridge assembly includes a lower combination plate, an upper combination plate, an internal structure support plate, and a ceiling connection fixing strip; the upper combination plate is provided at the upper end of the three-way bridge assembly, and the lower combination plate is fixedly connected to the upper combination plate by bolts.

[0007] Preferably, an internal structure support plate is provided between the lower composite plate and the upper composite plate, and the upper and lower ends of the internal structure support plate are respectively fixedly connected with the inner wall bolts of the upper composite plate and the lower composite plate, so that the internal space division and structural reinforcement of the lower composite plate and the upper composite plate are realized by relying on the internal structure support plate, and the risk of compressive deformation of the internal structure of the lower composite plate and the upper composite plate caused by load overload is effectively prevented.

[0008] Preferably, a ceiling connection fixing strip is provided on the upper end surface of the upper combined plate, and the ceiling connection fixing strip is fixedly connected to the upper combined plate by bolts.

[0009] Preferably, the upper end surfaces of the three-way bridge assembly, the high and low connecting bridge, the long straight bridge and the short straight bridge are all provided with ceiling connecting fixing strips, and the ceiling connecting fixing strips are fixedly connected to the upper end surfaces of the three-way bridge assembly, the high and low connecting bridge, the long straight bridge and the short straight bridge by bolts.

[0010] Preferably, a plane splicing block is arranged on the outer side of the connection between the high and low connecting bridge and the long straight bridge, and the plane splicing block is fixedly connected to the high and low connecting bridge and the long straight bridge by bolts, so that the plane splicing block strengthens the stability of the connection between the long straight bridge and the high and low connecting bridge.

[0011] Preferably, a corner splicing block is provided on the outside of the connection between the three-way bridge frame assembly and the short straight bridge frame and the high and low connecting bridge frame, and the corner splicing block is fixedly connected to the short straight bridge frame, the three-way bridge frame assembly and the high and low connecting bridge frame by bolts, and cooperates with the corner splicing block and the plane splicing block to achieve the convenience and stability of the segmented splicing of each bridge frame.

[0012] Beneficial effects of the utility model:

[0013] 1. The existing cable trays are unstable when spliced ​​during super-long connections, which may cause the cable to be underloaded and deformed due to pressure. The three-way cable tray components, high and low connection cable trays, long straight cable trays, and short straight cable trays are independently hoisted and installed through the ceiling connection fixing strips, which effectively shares the hoisting load-bearing force of each segmented cable tray, and cooperates with the corner splicing blocks and plane splicing blocks to achieve the convenience and stability of segmented splicing of each cable tray. Finally, the internal structure support plate is used to realize the internal space division and structural reinforcement of the lower and upper combined plates, effectively preventing the risk of compression deformation of the internal structure of the lower and upper combined plates caused by overload. This solves the problem that the existing cable trays are unstable when spliced ​​during super-long connections, which may cause the cable to be underloaded and deformed due to pressure.

[0014] 2. Through the setting of the external suspension connection block, the external suspension connection block effectively improves the load-bearing performance of each bridge segment, prevents shaking, and improves stability. BRIEF DESCRIPTION OF THE DRAWINGS
