Abstract

The invention discloses a pier-encircling clamp device, which comprises a mounting frame, a traversing frame, a bracket, anchor block racks, anchor blocks, connecting rods, a traversing hydraulic cylinder, a rotary hydraulic cylinder and a support hydraulic cylinder, wherein the mounting frame is connected with a mounting base on a support leg hydraulic cylinder of a to-be-clamped device, the traversing frame is installed below the mounting frame, the bracket is suspended below the traversing frame, the anchor block racks which are provided with the anchor blocks at the bottoms are respectively installed on the two sides of the bracket in groups of twos, the connecting rods are respectively connected with two anchor blocks at the same side, one end of the traversing hydraulic cylinder is fixed on the traversing frame and the other end thereof is fixed on the bracket for pushing the bracket to traverse horizontally, one end of the rotary hydraulic cylinder is connected with the bracket and the other end thereof is connected with the connecting rods for enabling the anchor block racks to rotate around the bracket, the support hydraulic cylinder is arranged below the bracket for jacking up the bracket and further clamping wedges. The pier-encircling clamp device can be used for effectively fastening the support leg of the to-be-clamped device with a pier without arranging embedded parts on the pier.

Description

technical field [0001] The invention relates to a fastening device for encircling bridge piers, in particular to a concrete bridge, in particular to a fastening device for encircling bridge piers for temporarily fixing erection equipment on bridge piers during erection construction of concrete box girders for high-speed railways. Background technique [0002] During the erection of modern concrete bridges, it is necessary to fasten the outriggers of the erection equipment to the piers. The usual method is to install embedded parts on the pier first, and then connect the anchor rods on the legs of the equipment to be fastened with the embedded parts on the pier during the erection process, so as to pre-tighten the anchor rods. fastening effect. This kind of fastening method mainly has the following deficiencies: [0003] 1. Embedded parts must be installed on the pier, and the embedded position of the embedded parts is not easy to control. Once the position is not suitable,...
