Description

Technical Field

[0001] The invention relates to a support device for bridge construction and inspection, and relates to the field of bridge construction and inspection, in particular to an automatically adjustable construction inspection support and an implementation method. Background Art

[0002] In recent years, with the development of economy, my country's infrastructure construction has developed rapidly. Among them, bridge projects, as the focus of my country's infrastructure construction, have sprung up like mushrooms after rain. There are countless bridges across rivers, across rivers and across lines, and the bridges are of various forms, including reinforced concrete bridges, prestressed steel structure bridges, steel bridges, steel-concrete composite beam bridges, etc. With the continuous increase in the number of bridges, some problems have gradually surfaced. One of the more important problems is that after the completion or operation of high-height bridges, due to the height problem, the detection, reinforcement and modification of defects and damages in the lower part of the bridge are difficult to carry out. Many bridges are delivered or operated with "injuries", which will seriously affect the safety of the bridges; on the other hand, our people have put forward strict requirements on the safety of my country's infrastructure construction. On-site engineers in my country have also taken countermeasures, such as using aerial platforms for inspection, in which workers inspect, modify and reinforce the lower part of the bridge. However, the area of ​​the platform on the aerial platform is limited, the construction area is limited, and it is difficult for construction workers and aerial platform drivers to communicate. The process is cumbersome, many working hours are required, the aerial platform is expensive, and the work safety is poor. The truss cage equipment is lowered from the upper part of the bridge, and workers inspect, modify and reinforce the lower part of the bridge in the truss equipment. However, the aerial stability of the truss equipment is poor, the operation is difficult, and the safety of personnel is poor. The modification bracket is made. The bracket takes the bridge as the mass point and is U-shaped. A long hanging basket is set below. Workers climb along the external stairs to the hanging basket to inspect, modify and reinforce the lower part of the bridge. Using this type of modification frame as equipment is currently a better solution, but this type of modification frame has a simple structure, and the component design in the equipment is backward, often one design for one bridge. When the bridge is completed, the modification frame equipment is equivalent to scrap iron, and this type of equipment is not suitable for the construction of variable-section bridges. Summary of the invention

[0003] In order to overcome the shortcomings of the existing technology, the present invention provides a support equipment and implementation method for bridge construction and inspection, which can be used for the appearance decoration work, inspection and detection and reinforcement work of various types of bridges (reinforced concrete bridges, prestressed concrete bridges, steel-concrete composite beam bridges, steel bridges and steel truss bridges); it has a semi-automatic function, and the staff can move the whole body in the operation room or by remote control equipment, and has better overall performance; multiple lines of defense are adopted in the hanging basket part to ensure the life safety of the workers working in the bottom hanging basket; it has a modular concept, can be reused many times, and can be applied to the appearance decoration work, inspection and detection and reinforcement work of variable-section bridges.
