Description

Technical Field

[0001] The utility model belongs to the field of cable bridge protection devices, in particular to a cable bridge protection device. Background Art

[0002] When existing cable trays are transported, several cable trays are directly stacked and tied with ropes and placed in the carriage of a transport vehicle. During transportation, shaking and vibration often occur due to road conditions, which not only creates noise but also causes wear and tear on the cable trays.

[0003] A Chinese patent with announcement number CN217321554U discloses a shock-absorbing and protective device for transporting cable bridges, comprising several shock-absorbing and protective bodies, wherein the shock-absorbing and protective bodies comprise a base plate, a protective frame, a sliding assembly and a shock-absorbing assembly. When the protective frame is stationary, the sliding assembly is centrally arranged at the upper end of the base plate, and several hooks are arranged at the upper end of the protective frame. Two sliding assemblies with symmetrical structures are arranged on both sides of the protective frame. There are two groups of shock-absorbing assemblies distributed on both sides of the protective frame, and the other ends of the two sliding assemblies on the same side are connected to the same shock-absorbing assembly. By installing several of the utility models in the carriage of a transport vehicle for transporting the cable bridge, when left and right swings or vibrations occur during transportation, the sliding assembly and the shock-absorbing assembly on the side of the protective frame are arranged to achieve a shock-absorbing effect and protect the cable bridge. The shock-absorbing and protective device for transporting the cable bridge in the application has a spring and a sleeve between the slide plate and the rubber pad, which results in a longer overall length of the device and limits the installation length of the spring, affecting the shock-absorbing effect.

[0004] In view of this, the present utility model is proposed. Utility Model Content
