Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant brackets, in particular to a lateral earthquake-resistant bracket for a bridge frame. Background Art

[0002] Cable tray is the abbreviation of cable tray. Cable tray refers to a rigid structural system composed of straight sections, bends, attachments and supports of cable trays or cable ladders, which has the function of protecting and supporting cables. On the side of the cable tray, there are usually earthquake-resistant brackets to fix the cable tray, so that the cable tray has stability. Then, most of the existing brackets are usually fixed on the side of the cable tray when protecting the cable tray. It is difficult to adjust the height of the bracket according to the height of different cable trays, thereby adjusting the fixed position of the cable tray. It may require multiple disassembly and replacement, which is more troublesome.

[0003] A search was conducted on the above-mentioned issues and it was found that in the currently disclosed prior art, such as the announcement number CN215452368U, a lateral seismic-resistant bracket for a bridge frame is proposed. The seismic-resistant bracket is formed by installing telescopic rods at both ends of the bridge frame, and a fixed rod is installed on the telescopic rod. The fixed rod can be moved up and down by adjusting the telescopic rod. After the movement is completed, a pin is inserted into the socket of the fixed rod and the movable rod to fix them. However, after the bracket is moved, if the moved position is relatively high, it may be difficult to manually insert the pin into the socket or it may require the use of tools to climb up, which is somewhat dangerous.
