An erection mechanism and erection method of an intelligently monitored lower string reinforcement system

Abstract

The invention discloses an erection mechanism and an erection method of an intelligently monitored lower chord reinforcement system. The erection mechanism includes a tensioning mechanism, a working platform, an intelligent monitoring system, and a chain rod lifter; the chain rod lifter and the chain rod of the lower chord reinforcement system One-to-one correspondence, one end of which is connected to the bridge, and the other end is connected to the corresponding chain rod, and the chain rod is suspended at the lower end of the bridge through the chain rod lifting ring; The corresponding tensioning mechanism is connected under the bridge, and the top of the strut can move along the longitudinal direction of the bridge through the tensioning mechanism to adjust the position of the connection point between the top of the strut and the bridge to tension the lower chord reinforcement system; the working platform is installed outside the tensioning mechanism , to provide working space for the staff to operate the tensioning mechanism; the intelligent monitoring system is used to monitor the pressure in the lower string reinforcement component, and give an alarm when the monitored pressure exceeds the internal preset pressure threshold. The invention can be manually assembled, and can be erected and installed synchronously with the bridge, and has high efficiency.

Description

technical field [0001] The invention relates to the technical field of road transportation, in particular to an erection mechanism and an erection method of an intelligently monitored lower string reinforcement system. Background technique [0002] The existing large-span emergency bridges in my country have shortcomings such as self-heaviness and long assembly and erection time. In order to further meet the increasingly stringent requirements of emergency support tasks, a chord system is used to externally reinforce the main body of the bridge under the bridge, which can reduce the weight of the main body of the bridge. Increase the bearing capacity of the bridge. [0003] Generally, the erection and installation of the chord system requires special equipment such as trailers, cranes or trucks, which takes up a lot of space, and it is inefficient to erect the chord system independently after the bridge erection is completed. Contents of the invention [0004] In view of t...
