Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge climbing bend butt joint assembly. Background Art

[0002] Cable tray is a supporting structure for laying cables. It is a commonly used equipment in electrical engineering installation. Cable trays are generally divided into trough, ladder and tray structures. In the actual installation process of cable trays, sometimes it is necessary to avoid obstacles such as pipes, beams, walls, etc. During the installation of cable trays, elbows need to be used for transition at the position of obstacles. Cable trays are composed of elbow accessories such as straight-through, horizontal tees, crosses, and up and down climbing bends. The traditional way to avoid is to measure the angle of the bridge and cut it before splicing it. This is more troublesome to operate, the angle is not easy to grasp, and there is a problem of poor adaptability of the docking angle. In order to complete the splicing, it is necessary to prepare multiple bend bridges with different turning angles to fully adapt to the installation. In addition, when the cable tray is assembled with up and down climbing bends, it is impossible to be completely horizontal and vertical. In order to adapt the corners more accurately, the bridge used at this location needs to be processed each time it is assembled, which requires high technical requirements for construction personnel (welding). In addition, the construction location is usually located on the roof or high, which is difficult to construct and has a long period of time. Therefore, when the existing cable tray is assembled by climbing up and down high bends, there are problems such as high difficulty and long period of assembly construction technology requirements.

[0039] As Figures 1 - 3 shown, a cable tray climbing bend docking assembly is used for the docking or transfer of cable trays. The cable tray includes two side plates and a connecting structure disposed between the two side plates. The connecting structure may specifically be a bottom plate or a connecting rod. A docking port is provided on one of the cable trays, that is, a notch is provided on the side plate. The other cable tray may be a transfer tray, and the cable tray climbing bend docking assembly docks the docking port of one cable tray with the transfer tray.

[0040] The cable tray climbing bend docking assembly includes a first connector 1, a second connector 2 and a first locking member 3. The first connector 1 includes a first adapter 11 and a first connector 12 for connecting to the cable tray, the first connector 12 is connected to the first adapter 11 at a first angle, and a first connection hole 13 is provided at the end of the first adapter 11. The second connector 2 includes a second adapter 21 and a second connector 22 for connecting to the cable tray, the second connector 22 is connected to the second adapter 21 at a second angle, and a second connection hole 23 is provided at the end of the second adapter 21. The first locking member 3 is passed through the first connection hole 13 and the second connection hole 23, and the first adapter 11 and the second adapter 21 are fastened through the first locking member 3. When docking, two sets of cable tray climbing bend docking assemblies are arranged on both sides of the docking interface on the cable tray, and each cable tray climbing bend docking assembly corresponds to the side plate of the cable tray on the side. The first connecting member 1 is connected to the side panel of the cable tray near the docking interface, and the second connecting portion 22 is connected to the side panel of another cable tray. At the same time, the first locking member 3 is passed through the first connecting hole 13 and the second connecting hole 23, and the first adapter portion 11 and the second adapter portion 21 are preliminarily locked, and then the angle between the first adapter portion 11 and the second adapter portion 21 is adjusted, and then the first adapter portion 11 and the second adapter portion 21 are locked. In this way, the side panel at the docking interface can be connected to the side panel of another cable tray through the cable tray climbing bend docking assembly, and the angle can be adjusted and locked, so as to realize the free adjustment of the climbing bend angle of the cable tray, improve the flexibility of the use of the tray, increase the convenience rate of the tray, thereby effectively improving the angle adaptability during docking.

[0041] In addition, when assembling the climbing bend, it is usually made manually. First, determine the size of the cable tray, draw the marking lines, cut out the butt joint of the cable tray, cut directly to the bottom of the cable tray, and then grind off the burrs. On-site cutting also requires on-site welding. Welding construction at heights on-site has problems such as inconvenient construction, high technical requirements for construction personnel (welding), large construction difficulty, and long cycle. Due to different technical levels of welding personnel, there are also significant differences in welding quality. After welding, grinding treatment is required, which seriously damages the galvanized layer, affects the corrosion resistance of the cable tray, and reduces the service life of the cable tray. On-site construction has a great impact on the working environment, generating significant noise, dust, and toxic and harmful gases, resulting in poor working conditions. In addition, on-site installation and welding at the construction site will damage the original surface treatment layer of the product and cannot be repaired, which is neither beautiful nor corrosion-resistant. When using the cable tray climbing bend docking assembly in the sample embodiment, on-site locking with the locking member is used instead of on-site construction. Compared with on-site production, it has a faster construction speed and a shorter construction cycle. Whether it is bottom operation or high-altitude operation, the main operation is locking, the construction is simple, and the technical requirements for construction personnel are low. The main operation is locking at normal temperature, which has little damage to the cable tray and can maintain the original strength, rust prevention, and corrosion resistance of the cable tray. With locking operation as the main operation, it is a low-noise operation, generating less dust and toxic and harmful gases, and effectively improving the working environment.

[0042] In further embodiments of some cable tray climbing bend docking assemblies, such as Figure 3 , Figure 4 shown, the end of the first adapter portion 11 is further provided with a first arc-shaped limiting groove 14, and the first arc-shaped limiting groove 14 is arranged on the circumference around the first connection hole 13. The end of the second adapter portion 21 is further provided with a second arc-shaped limiting groove 24, and the second arc-shaped limiting groove 24 is arranged on the circumference around the second connection hole 23. The cable tray climbing bend docking assembly further includes a second locking member 4, and the second locking member 4 passes through the first arc-shaped limiting groove 14 and the second arc-shaped limiting groove 24. The second locking member 4 restricts and locks the relative angle between the first adapter portion 11 and the second adapter portion 21. The end of the first adapter portion 11 is provided with a first arc-shaped limiting groove 14, and the end of the second adapter portion 21 is further provided with a second arc-shaped limiting groove 24. The second locking member 4 passes through the first arc-shaped limiting groove 14 and the second arc-shaped limiting groove 24. On the one hand, the first adapter portion 11 and the second adapter portion 21 are locked by the second locking member 4, that is, the first locking disc and the second locking disc are locked. Compared with the first locking member 3, after the second locking member 4 is provided, there are two locking points, namely the first locking member 3 and the second locking member 4, and the locking between the first connecting member 1 and the second connecting member 2 is more firm.

Taking the first locking member 3 as the axis and passing through the first connection hole 13 and the second connection hole 23 on the two locking disks to initially lock the two locking disks, the angle of the cable tray can be adjusted. Rotate around the first locking member 3 to a suitable angle, and then fully lock the two locking disks. The ends of the first adapter part 11 and the second adapter part 21 form a semi-circular structure, which ensures good bending freedom of the cable tray, can achieve horizontal placement, 90-degree bending, and other angles between horizontal placement and 90-degree bending. It has strong practicability, and the overall structure is relatively simple, the assembly is simpler, time-saving and labor-saving, and it is suitable for large-scale promotion.
