Abstract

The invention discloses a suspension device for bridge engineering construction, comprising hoisting mechanisms, connecting assemblies, a moving table, a mounting cover and a mounting frame. The mounting cover is vertically arranged in the middle of the top of the mounting frame; lifting channels are formed in the mounting cover in the vertical direction; a driving device used for driving the moving table to move in the vertical direction is arranged on the mounting cover; adjustment channels are formed in the mounting frame in the horizontal direction; a plurality of lifting channels, adjustment channels, hoisting mechanisms and connecting assemblies are evenly arranged around the mounting frame; each connecting assembly comprises a mounting table, a second connecting table, a connectingrod and a first connecting table; the hoisting mechanisms are arranged on the mounting tables; the mounting tables are slidably arranged on the mounting frame in the horizontal direction; the second connecting tables are arranged on the mounting tables; the two ends of the connecting rods are rotatably connected with the second connecting tables and the first connecting tables; and the first connecting tables are arranged on the moving table. The suspension device can conveniently adjust the hoisting distance, can be used for hoisting construction equipment or materials with different sizes, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a suspension device for bridge engineering construction. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. [0003] During the construction of a bridge project, it is generally necessary to use a suspension device to lift construction equipment or materials. The existing suspension device is not convenient for adjusting the lifting distance, and it is not convenient for lifting construction equipment or materials of different sizes, and the scope of use is small. Contents of the invention [0004] In view of the deficiencies in the...
