Abstract

The invention belongs to the technical field of cable installation, and particularly relates to cable bridge auxiliary installation equipment which comprises lifting assemblies, the lifting assemblies are arranged on the two sides of a tray in the width direction, and the lifting assemblies act on a bottom plate of the tray; clamping assemblies are arranged on the two sides, in the length direction of the tray, of the lifting assembly correspondingly, and the clamping assemblies act on side plates of the tray; the clamping assembly comprises clamping pieces, the clamping pieces are located on the inner side and the outer side of the tray, the clamping pieces are pneumatically controlled, and the clamping pieces move by introducing gas and act on the inner side and the outer side of a side plate of the tray, so that the bridge is installed and fixed. The air bag type clamping piece, the multi-stage telescopic structure clamping piece and the clamping piece combining the reset spring and the air bag are adopted, so that uniform distribution of clamping force is ensured, and the problem of local stress concentration possibly caused by a traditional hard clamp is solved.
