Abstract

The invention relates to the technical field of power equipment, and discloses a self-compensating cable tray, comprising a bridge box, one end of the bridge box is fixedly connected with an adjustment protrusion, and the other end is provided with an adjustment groove, one end of the adjustment protrusion is A rubber layer is fixedly connected, a clamping groove is formed on the outer side of the top of the bridge box, and symmetrical buckle protrusions are fixedly connected at both ends of the outer side of the bottom of the bridge box. Through the designed adjustment protrusions, adjustment grooves, rubber layers and locks, the present invention enables the adjacent bridges to obtain the prestress provided by the rubber layers and the locks during installation, so that the rubber layers and the locks can be separated when the bridges are stretched and displaced. The provided prestress will be eliminated to ensure the safety of the bridge frame. When the force generated by the expansion and displacement of the bridge frame makes the prestress invalid, the lock will be loosened. At this time, the expansion and displacement of the bridge frame will be freed by adjusting the protrusions and adjusting grooves. Sliding completes automatic adjustment, while avoiding the falling of the bridge.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a self-compensating cable tray. Background technique [0002] The cable tray is a device that protects and supports the laying of cables in the electrical system. However, due to the thermal expansion and contraction caused by temperature changes and the influence of external dynamic loads such as wind, the connection between the two ends of the tray will expand and displace, while the adjacent The bridge frame is generally fixed by a locking device, so that the bridge frame is prone to impact fracture during expansion and displacement, and under the influence of long-term dynamic load, the locking device at the connection is prone to loosening, causing the bridge frame to fall, and at the same time. The cable at the connection is affected by the expansion and displacement of the bridge frame, and the outer insulation layer of the cable will be rubbed and cut at the co...
