Safe and reliable auxiliary hoisting structure for bridge construction

Abstract

The invention discloses a safe and reliable auxiliary hoisting structure for bridge construction, and relates to the technical field of bridge construction. The hoisting structure comprises a hoistingbox, wherein the outer of the hoisting box is provided with an installation groove; a limiting plate is fixedly arranged on the outer surface of the hoisting box; and an installation column is arranged at the upper portion of the hoisting box. The safe and reliable auxiliary hoisting structure for bridge construction promotes a cover plate group to move upward through a connecting column during rising of a connecting frame, so that the cover plate group moves above the hoisting box in a guide slot through the guide slot until the hoisting box is capped, and accordingly, the closure of the device is improved during using, and the problem of spilling during conveying materials is avoided; and in the process of continuous rise of an auxiliary plate, pressing blocks on both sides are pulled by a connecting rod to rotate with a supporting block as the center of a circle, so that the cover plate group is pressed by the pressing blocks during pulling to a limit position, and thus, the safetyof a conveying process is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a safe and reliable auxiliary hoisting structure for bridge construction. Background technique [0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Bridges generally consist of superstructures, substructures and subsidiary structures. The superstructure mainly Refers to the bridge span structure and support system, the substructure includes abutments, piers and foundations, and the auxiliary structures refer to the bridge head abutment, conical slope protection, revetment and diversion works, etc. Bridges are divided according to the structural system, including girder bridges, arch bridges, There are four basic systems of rigid frame bridge and suspension cable load-bearing. In the process of bridge construction, hoisting devices ar...
