Bridge swivel construction intelligent control system

Abstract

The invention discloses a bridge swivel construction intelligent control system which comprises a lifting swivel mechanism, a PLC control module and a remote control module. The lifting swivel mechanism is provided with a pier column and a beam body pouring platform, and the beam body pouring platform is used for pouring a rotary beam body. The pier column is used for supporting the rotary beam body in the lifting swivel process. The PLC control module is provided with a PLC and a touch screen, the PLC is connected with the touch screen, and the touch screen is provided with a data setting module, a display module, an automatic module and a manual module. The PLC is used for controlling the lifting swivel process of the rotary beam body. The remote control module is provided with an intelligent terminal and a database connected with the intelligent terminal, the intelligent terminal is wirelessly connected with the PLC control module, and all data and lifting swivel simulation data inthe lifting swivel process are stored in the database. The system has the beneficial effects that a new bridge installation mode is adopted, transport is convenient, a lifting rotary device can be recycled, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an intelligent control system for bridge swivel construction. Background technique [0002] With the rapid improvement of the country's economic level, the transportation industry has also developed vigorously. Due to the influence of some terrain or existing traffic facilities, bridge hoisting and swivel construction are more and more widely used in bridge construction. Compared with traditional bridges, the swivel hoisting and bridge construction techniques have the characteristics of not interfering with traffic, uninterrupted navigation, crossing deep ditches, rivers, and roads with frequent traffic, and the construction is fast and cost-effective. [0003] Due to the heavy weight of the swivel body, the long bridge, irregular shape of the bridge, and the complex geographical environment of the bridge, it is difficult to control the angle during the hoisting and ...

AI Technical Summary

Problems solved by technology

[0005] First: the weight of the poured beam is huge, the geographical environment of the bridge is complex, the transportation process of the beam is difficult, the transportation cost is high, and it consumes manpower and material resources;

[0006] Second: In the process of hoisting by crane or spreader, due to the action of wind, the beam body is prone to sway. In the existing hoisting process, it is often necessary to detect the wind speed within a radius of several kilometers. Once the wind speed exceeds the hoisting wind speed, it needs to stop Hoisting;

[0007] Third: The risk factor of hoisting construction is high. In order to facilitate the observation of construction, the construction time is generally during the day, and it is inevitable that there will be road blockades, causing traffic congestion around

[0008] Fourth: Due to the use of a spreader crane for hoisting and swivel construction, due to the long hoisting rope, it is easily affected by the vibration of the crane and the wind, resulting in low hoisting accuracy, difficult swivel construction, and long construction time of the bridge, which cannot meet the requirements

[0009] Fifth: In the process of bridge positioning and installation, the position of the beam body is considered to be observed and controlled, and the observation accuracy is low and it is difficult to control

[0010] Sixth: During the swivel construction, the motor and other swivel components used in the swivel construction cannot be recycled, which wastes resources and high construction costs
