[0019] Example

[0020] refer to Figures 1-4 An improved ladder-type cable tray includes two symmetrically arranged ladder plates 1 and a crossarm 2 detachably arranged between the two ladder plates 1. There are multiple crossarms 2. A first support frame 21 is provided on one side of the top of each crossarm 2, and a second support frame 22 is provided on the other side of the top of each crossarm 2, which can be stacked vertically with the first support frame 21 on the adjacent crossarm 2. The arrangement of the first support frame 21 and the second support frame 22 increases the support area at the bottom of the cable tray, reduces the pressure on the crossarm 2, and avoids damage or deformation of the crossarm 2 during long-term use. The vertical stacking of the first support frame 21 and the second support frame 22 on the adjacent crossarm 2 strengthens the tightness of the connection between each crossarm 2, thereby improving the stability and safety of the cable it carries and extending its service life. A support column 23 is fixedly connected to the bottom end face of the crossarm 2.

[0021] refer to Figure 3 The bottom inner side of the ladder plate 1 is provided with an extension plate 11 along the length direction of the ladder plate 1. The top end face of the extension plate 11 is provided with a plurality of evenly distributed guide plates 12. The bottom end face of the extension plate 11 is provided with a fixing seat 13 corresponding to the guide plates 12. The fixing seat 13 is provided with a first fixing hole 15 through which a fixing bolt 14 can be inserted.

[0022] Furthermore, the support rod 24, which can be rotatably engaged with the fixed base 13, is hinged to both the left and right sides of the support column 23. The end of the support rod 24 away from the support column 23 is provided with a second fixing hole 25 that is connected to the first fixing hole 15. The support rod 24 and the support column 23 are provided to further increase the support strength and load-bearing capacity of the crossbeam 2, thereby improving the overall stability of the cable tray.

[0023] Furthermore, mounting plates 26 are symmetrically and fixedly connected to the bottom end faces of the crossarms 2 on both sides of the bearing column 23. The bottom end face of the mounting plate 26 is provided with a guide groove 27 for the guide plate 12 to be inserted. Through the setting of the guide groove 27 and the guide plate 12, the installation of the crossarm 2 and the ladder plate 1 can be guided and connected, so that the crossarm 2 and the ladder plate 1 are initially fixedly connected.

[0024] Furthermore, a first reinforcing block 28 with a triangular structure is fixedly connected to the inner side of the mounting plate 26. The first reinforcing block 28 strengthens the connection between the mounting plate 26 and the crossbeam 2. A second reinforcing block 29 with a triangular structure is symmetrically fixedly connected to both sides of the mounting plate 26. The second reinforcing block 29 increases the contact area between the crossbeam 2 and the ladder plate 1, disperses the stress area, and improves the load-bearing strength of the crossbeam 2.

[0025] The working principle of this utility model:

[0026] During installation, first, align the guide groove 27 on one of the crossarms 2 with the guide plate 12 at one end of the ladder plate 1 and insert it. Then, align the guide grooves 27 on the other crossarms 2 with the guide plates 12 on the ladder plate 1 one by one, following the first crossarm 2 that was inserted. After insertion, the first support frame 21 and the second support frame 22 on the adjacent crossarms 2 are stacked one on top of the other. Finally, rotate the support rod 24 into the fixing seat 13. At this time, the second fixing hole 25 on the support rod 24 is connected to the first fixing hole 15 on the fixing seat 13. Insert the fixing bolts 14 one by one into the first fixing hole 15 and the second fixing hole 25 to complete the installation of the cable tray. When disassembling, reverse the above operation to complete the disassembly of the cable tray.
