Abstract

The invention discloses a quick positioning device for a bridge cantilever, which comprises two fixing bases. Supporting blocks are uniformly and fixedly mounted on the upper end surfaces of the fixingbases; a screw rod is movably mounted between the two supporting blocks; a transmission gear is fixedly mounted on the outer side of one end of the screw rod; a motor gear is mounted on one side of the transmission gear; a motor is fixedly mounted at one end of the motor gear; and a movable sliding block is movably installed on the outer side of the screw rod, a connecting block is fixedly installed at the upper end of the movable sliding block, distance measuring sensors are installed on the two sides of the connecting block correspondingly, a telescopic supporting rod is fixedly installed on the upper surface of the connecting block, and an installing base is fixedly installed at the upper end of the telescopic supporting rod. By installing the distance measuring sensor, the screw rod,the movable sliding block, the laser receiver and the laser emitter, auxiliary positioning can be conducted when bridge cantilevers are in butt joint, positioning of a bridge is facilitated, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a rapid positioning device for a bridge cantilever. Background technique [0002] With the rapid development of social economy, bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. Buildings that are erected to make traffic more convenient. Bridges are generally composed of superstructure, substructure, supports and auxiliary structures. The superstructure is also called bridge span structure, which is the main structure for crossing obstacles; Bridge piers and foundations; supports are force transmission devices set at the supporting places between bridge span structures and bridge piers or bridge abutments; auxiliary structures refer to bridge head straps, conical slope protection, bank revetments, diversion projects, etc. Bridge cantilever quick positioning devices are Refers to the auxiliary d...
