Description

Technical Field

[0001] The invention relates to a combined trough-type cable bridge and an assembling method thereof, belonging to the technical field of electromechanical installation. Background Art

[0002] At present, trough-type cable trays are widely used in laying communication cables, computer cables, thermocouple cables, and control cables for highly sensitive systems. They can effectively shield external interference and protect cables in heavily corrosive environments, greatly improving the service life and use effect of cables. However, existing trough-type cable trays have uniform specifications. In order to save space, a group of cable trays often contains multiple types of cables. When there are too many types of cables, the tray will appear very messy, and different cables are easily entangled together. When a group of cable trays 6 is not enough to place more cable bundles 7, such as Figure 9 As shown, this can only be achieved by increasing the number of cable trays 6.

[0003] The existing trough-type cable trays have the following problems: the specifications are large and the width is fixed, and different sizes of space cannot be provided according to actual needs; the space saving leads to troublesome cable replacement and maintenance; the dense placement of cables during use causes overheating, reduces the life of the cables, and even causes fires in severe cases; and because the cable trays are placed in multiples, the corresponding turning joints must also be specially customized and replaced, which invisibly increases the construction cost. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a combined trough-type cable bridge, which can adjust the bridge space according to construction needs.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is as follows:

[0006] A combined trough-type cable tray, which is composed of straight-through cable troughs and corner bends.

[0007] The straight-through cable trough comprises a plurality of mutually overlapping quasi-straight plates and two L-shaped slot plates installed outside the quasi-straight plates, the two sides of the quasi-straight plates are bent inwards to form straight plate curling edges, the horizontal end of the L-shaped slot plate has a slot plate curling edge bent inwards, the vertical end of the L-shaped slot plate has a slot plate curved edge bent inwards, the quasi-straight plates are connected by buckling adjacent straight plate curling edges, and the quasi-straight plates and the L-shaped slot plates are connected by buckling the straight plate curling edges and the slot plate curling edges.

[0008] The corner elbow is formed by splicing a straight trough with an internal corner plate and an external corner plate. The internal corner plate has an internally folded internal corner bottom flange and an internal corner top flange, and the internal corner bottom flange and the internal corner top flange respectively match the shapes of the trough flange and the trough bend of the trough plate. The external corner plate is provided with an externally bent external corner bottom flange and an external corner top flange, and the external corner bottom flange and the external corner top flange respectively match the shapes of the trough flange and the trough bend of the L-shaped trough plate.

[0009] Further, the corner elbow includes three forms. The first form is a right-angle turn form, the second form is a "T" shape, and the third form is a "cross" shape.

[0010] Further, the first form of the corner elbow is composed of two groups of straight-like plates to form a right-angle combination body. L-shaped trough plates are respectively installed on the inner and outer sides of the right-angle combination body. An internal corner plate is installed on the L-shaped trough plate on the inner side of the right-angle combination body, and an external corner plate is installed on the L-shaped trough plate on the outer side of the right-angle combination body.

[0011] Further, the second form of the corner elbow is composed of two groups of straight-like plates to form a "T" shaped combination body. L-shaped trough plates are respectively installed on the outer side and at the two right angles of the "T" shaped combination body. Internal corner plates are installed on the L-shaped trough plates at the two right angles.

[0012] Further, the third form of the corner elbow is composed of two groups of straight-like plates to form a "cross" shaped combination body. L-shaped trough plates are respectively arranged at the four right angles of the "cross" shaped combination body. Internal corner plates are installed on the L-shaped trough plates at the right angles.

[0013] Further, the L-shaped trough plate, the straight-like plate, the internal corner plate and the external corner plate are all made of stamped steel components.

[0014] The present invention also provides an assembly method for the above-mentioned combined trough-type cable tray, including the following steps:

[0015] S1. According to the horizontal direction of cable laying, position on the floor. Determine the width of the straight trough according to the number of cables, and splice with straight-like plates and L-shaped trough plates to reach the required width of the straight trough;

[0016] S2. According to the cable direction, position on the floor and select the form of the corner node;

[0017] S3. Complete the splicing of the corner elbow at the corner node;

[0018] S4. Connect the spliced straight trough with the corner elbow to complete the laying of the cable tray.

[0019] The working principle of the present invention is that the combined trough-type cable tray is formed by connecting straight troughs with corner elbows. The straight trough is composed of a straight plate-like component and L-shaped trough plates on both sides, and its width can be adjusted by changing the number of straight plate-like components; the internal corner plate is installed by buckling the flanging at the bottom of the internal corner and the flanging at the top of the internal corner on the inner sides of two perpendicular L-shaped trough plates. The external corner plate can be installed by buckling the flanging at the bottom of the external corner and the flanging at the top of the external corner on the outer sides of two perpendicular L-shaped trough plates. The corner elbow can flexibly select different assembly structural forms according to the corner nodes.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The present invention can flexibly select the width of the trough-type cable tray according to the number of cables and on-site requirements, without the need to additionally increase the number of cable trays, eliminating the problem of poor space utilization caused by large module and fixed specifications. It improves the flexibility of cable tray construction layout and reduces the time cost and construction cost.

[0022] 2. The present invention can flexibly assemble the corner elbow without the need to customize a special horizontal corner joint according to the specific use specifications of the cable tray.

[0023] 3. The present invention optimizes the internal space of the cable tray, is convenient for construction, and is especially suitable for the laying construction of complex cables. BRIEF DESCRIPTION OF THE DRAWINGS
