Description

Technical Field

[0001] The invention relates to the field of bridge maintenance and reinforcement construction, and in particular to a convenient sliding track hanging rail system and a control system for bridge maintenance. Background Art

[0002] With the rapid development of my country's transportation industry, bridge structures are facing increasing load pressure, and are also adversely affected by factors such as natural conditions and geographical environment. Especially for cross-river and cross-sea bridges, bridges are constantly eroded by river water or sea water, which leads to problems such as steel bar corrosion, concrete cracking and peeling that endanger the safety of bridge structures during long-term use. Therefore, it is of great significance to prevent and treat the diseases that occur during the use of bridges and to carry out repair, reinforcement and maintenance of bridges in a timely manner to ensure traffic safety and extend the service life of bridges.

[0003] In the repair and reinforcement of bridge piers across rivers or across seas, common ways to transport materials to the pier cap include truck cranes and floating cranes. Truck cranes are a common way to lift equipment and materials to the cap by using a crane on the bridge deck. However, the use of cranes will occupy lanes, which will have a certain impact on traffic, and is also subject to restrictions such as limited crane locations and the inability to transport under the bridge. In contrast, floating cranes use cranes to transport and lift materials on the water. Floating cranes have the advantages of large lifting capacity, strong flexibility, and high work efficiency, but they also have disadvantages such as high cost of use, dependence on the water environment, great influence of weather, environmental problems, and occupation of waterways. Especially for bridges with smaller spans, floating cranes may seriously affect water navigation conditions. Therefore, the present application proposes a convenient sliding track hanging rail system for bridge maintenance.

[0004] During the use of the sliding track hanging rail system, the staff generally relies on work experience to judge whether there are safety hazards, and then manually control the start and stop of each motion system. This will not only lead to misjudgment and affect construction, but also have certain safety hazards. Therefore, this application proposes a control system for a convenient sliding track hanging rail system for bridge maintenance. Summary of the invention
