A guide rail 207 is provided, which is connected to a sliding sleeve 208. Two cable trays 104 can be assembled through a connecting plate 1. Then, a connecting block 2 is installed in a suitable position through the assembly hole 204. Since the connection between the two cable trays 104 is not very rigid, the connecting block 2 can be placed on top. Then, the position of the connecting block 2 and the cable tray 104 is fixed with bolts. The bottom of the connecting block 2 is provided with a composite rubber buffer pad, which can absorb high-frequency vibration energy and reduce shock. At the same time, extension rods 202 are symmetrically provided on both sides of the connecting block 2. By rotating the limiting cylinder 203, the limiting cylinder 203 can be made to abut against the cable tray 104 to prevent the cable tray from deforming and affecting the internal cables. At the same time, when vibration occurs, the damping spring 205 at the bottom of the fixing plate 206 provides shock absorption.
[0025] The connecting plate 1 has a first fixing hole that matches the mounting groove 101. The connecting plate 1 is fixed to the cable tray 104 by bolts. This bolt connection facilitates future expansion or partial replacement of the cable tray, allowing for segmented maintenance without damaging the main structure. The cover plate 103 can slide along the length of the cable tray 104. The cover plate 103 has a second fixing hole that matches the mounting hole 102. The cover plate 103 is fixed to the cable tray 104 by bolts. The top is equipped with an inspection door, which is connected by a hinge and fixed to the cover plate 103 by bolts, facilitating the later maintenance of the bridging internal components. The connecting block 2 is fixed to the cable tray 104 by bolts, and the side of the connecting block 2 near the cable tray 104 is equipped with a composite rubber buffer pad for shock absorption. The sliding sleeve 208 can move along the length of the guide rail 207. The sliding sleeve 208 is equipped with a threaded hole, and the sliding sleeve 208 is fixed to the guide rail 207 by a threaded rod, facilitating the adjustment of the end ring position.
[0026] In this embodiment, please refer to Figure 1 and Figure 2The top of the sliding sleeve 208 is symmetrically provided with a lower end ring 3, and the top of the lower end ring 3 is provided with an upper end ring 301.

Several limiting blocks are provided between the upper end ring 301 and the lower end ring 3 to cooperate with the compression spring 303 to adapt to cables of different sizes. The end rings and the cover plate 103 protect the cable and minimize the impact on the cable tray and cable.

One end of the extension rod 202 is provided with a threaded groove, and the limiting cylinder 203 is adapted to the threaded groove to hold the cable tray in place and prevent it from deforming.
[0028] The working process of this utility model is as follows: When using this type of combined anti-vibration and shock-absorbing cable tray, firstly, two cable trays 104 can be assembled through the connecting plate 1. Then, the connecting block 2 is installed in a suitable position through the assembly hole 204. Since the connection between the two cable trays 104 is not very rigid, the connecting block 2 can be placed on top. Then, the position of the connecting block 2 and the cable tray 104 is fixed with bolts. The bottom of the connecting block 2 is provided with a composite rubber buffer pad, which can absorb high-frequency vibration energy and reduce shock. At the same time, extension rods 202 are symmetrically provided on both sides of the connecting block 2. By rotating the limiting cylinder 203, the limiting cylinder 203 can be made to abut against the cable tray 104 to avoid the cable tray deformation affecting the internal cables. At the same time, the cables are limited by two end rings, and the two end rings are fixed in position by bolts. Several limiting blocks are provided between the upper end ring 301 and the lower end ring 3, which work with the compression spring 303 to adapt to cables of different sizes. When vibration occurs, the damping spring 205 at the bottom of the fixing plate 206 reduces shock.
