Abstract

The invention discloses a bridge expansion device locating tool which comprises a base. A bridge expansion device body is arranged at the upper end of the base. A limiting device is arranged on the side wall of the base and comprises two first fixing boards. Second fixing boards are arranged on the side walls at the opposite ends of the two first fixing boards. Fixing grooves are formed in the side walls of the two first fixing boards. Rack boards are connected with the inner portions of the two fixing grooves in a sliding mode. The side walls of the two second fixing boards are fixedly connected with multiple first motors. The tail ends of output shafts of the multiple first motors are fixedly connected with first driving wheels matched with the rack boards. The side walls of the two rackboards are provided with extension boards. A transverse rod is connected between the side walls of the two extension boards. A connecting block is fixedly connected to the side wall at the bottom ofthe transverse rod. The tool is reasonable in structural design and easy to operate, and both the locating efficiency and the locating accuracy of the tool can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a positioning tool for a bridge expansion device. Background technique [0002] With the rapid development of road transportation, the road traffic volume and vehicle load are also increasing, which puts forward higher requirements for the performance and production capacity of road bridge expansion devices. Bridge telescopic device means that in order to meet the deformation requirements of the bridge deck, telescopic devices are usually installed between the ends of two girders, between the girder end and the abutment, or at the hinge position of the bridge. The traditional modular bridge telescopic device has a relatively long production cycle due to the limitation of the traditional process. Especially in the northern region, the construction season is often concentrated, and the demand for expansion devices is also relatively concentrated. The low-capacity proces...
