Description

Technical Field

[0001] The utility model relates to a device for laterally translating the trailing trailer of a shield machine, belonging to the technical field of tunnel construction. The utility model also relates to a trailing trailer translation device of a shield machine adopting the above-mentioned lateral translation device. Background Art

[0002] With the continuous development of urban rail transit, shield tunneling construction has been widely applied. Since most subway stations are built in bustling areas such as the city center. To ensure smooth traffic during construction, most subway stations in busy traffic areas adopt a semi-covered excavation (subsurface excavation) structure for construction, which makes it necessary to laterally translate the shield machine in the shield shaft to the construction portal of the covered excavation (subsurface excavation) structure for starting, resulting in a long shield assembly period and increased project duration and personnel input. Currently, for the lateral translation tooling of the trailing trailer of the shield machine, most use customized translation trolleys, but the customized translation trolleys are only applicable to construction under the same translation working conditions and are often inapplicable when the construction site working conditions change, with a low recyclability rate, resulting in high construction costs and resource waste. Content of the Utility Model

By providing power through the winch and the pulley block, the rail car slag bucket support can drive the steel platform to move laterally along the first steel rails, thereby realizing the lateral translation of the trailing trailer of the shield machine. The rail car slag bucket support in the utility model is the base of the rail car slag bucket, with high structural strength and large load-bearing capacity, and can form a reliable moving load-bearing platform to ensure the reliable lateral translation of the trailing trailer of the shield machine.

[0006] Further, to ensure the reliable movement of the slag bucket holders of the three rail vehicles, the ends of the slag bucket holders of the three rail vehicles are connected together by steel wires, and the steel wire of the winch is wound around the pulley block and then connected to the steel wire connecting the slag bucket holders of the three rail vehicles.

Using the winch and the pulley block as the power, it can conveniently realize the transverse movement of the slag bucket holders of the rail vehicle and the profiled steel platform, thereby realizing the transverse translation of the trailing trailer of the shield machine.
