Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a high-strength earthquake-resistant bracket for a bridge. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supports and installation accessories. The cable trays can be erected independently in buildings or laid on various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts need to be galvanized and installed in the open-air cable tray outside the building.

[0003] During the installation process, the cable tray needs to be installed with a bracket and a top plate or a wall. However, when the bracket and the cable tray are installed, the corresponding bracket needs to be installed according to the width of the tray, which increases the requirements for the dimensional accuracy of the bracket.

When the bidirectional screw 302 rotates, the sleeve 303 can be driven to move along the inner wall of the mounting cylinder 301. Both the outer side of the sleeve 303 and the inner side of the mounting cylinder 301 are square prism structures. The sleeve 303 is limitedly inserted into the inner side of the mounting cylinder 301, and the bidirectional screw 302 slides through the outer side of the movable plate 7.
