Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a transport trolley for dismantling a concrete bridge. Background Art

[0002] After long-term vehicle loads and external environment, the working performance and completion time of concrete cable-stayed bridges have been greatly degraded; at the same time, faced with the increasing traffic volume, they are facing demolition operations. Among them, the main beam removal operation is the most critical part of the concrete cable-stayed bridge demolition operation. The main transportation methods after the main beam is removed are as follows: truck crane or crawler crane method. In actual production, truck crane or crawler crane usually needs to treat the foundation to meet its requirements for the bearing capacity of the foundation. If it is in the water, it is necessary to build a temporary construction bridge or construction ship, which makes the temporary construction cost higher; gantry crane, it needs to lay tracks at the demolition site, and its scope of use is limited.

[0003] Based on the above, it can be seen that the existing technologies have the following technical problems: truck cranes or crawler cranes usually need to treat the site foundation, and their arms are long, which makes them difficult to use in narrow spaces; gantry cranes need to set up tracks, and they are only used on land or need to set up temporary bridges. Therefore, there is an urgent need for a transport trolley for main beam removal that can utilize the existing bearing capacity of the beam body and can achieve the purpose of removing the main beam without treating the foundation or setting up temporary construction facilities to increase temporary construction costs.
