Abstract

The invention relates to the technical field of bridge demolition, and discloses a bridge demolition safety protection device which comprises a supporting mechanism, the supporting mechanism comprises a supporting base and a supporting positioning block, a positioning groove is formed in the upper side of the supporting base, and an inclined supporting column is arranged at the position, located on one side of the positioning groove, of the upper side of the supporting base. The supporting and positioning block comprises a supporting and positioning block body, and a supporting clamping groove is formed in the upper side of the supporting and positioning block body. A movable clamping block can be moved by pulling a shifting plate, a supporting positioning block is embedded in a positioning groove, a plurality of second positioning blocks are embedded in a designated position, the loosening condition can be avoided, then the shifting plate is loosened, a spring recovers deformation, and the movable clamping block is driven to abut against a supporting base; a worker can conveniently and preliminarily fix the supporting positioning blocks and the supporting base, then a corresponding screw rod sequentially penetrates through one set of first positioning blocks and then is fixed to the supporting base, and the worker can conveniently conduct installation.

Description

technical field [0001] The invention relates to the technical field of bridge dismantling, in particular to a bridge dismantling safety protection device. Background technique [0002] With the development of bridge construction in China, more and more large-span continuous beam (rigid frame) bridges need to be demolished because their functions and structures do not meet the requirements of new construction planning and technical standards. The core issue of bridge demolition is safety. The safety accidents of bridge demolition illustrate this point. How to ensure the safety of bridge demolition from the perspective of construction methods and safety control technology is a major issue facing the bridge demolition project. [0003] Existing bridge demolition mostly adopts blasting method, direct demolition method and mechanical hoisting method, but bridges across existing traffic lines are generally demolished by mechanical method. The mechanical demolition method refers t...
