Tunnel passing girder transporting vehicle

Abstract

The invention provides a tunnel passing girder transporting vehicle. The tunnel passing girder transporting vehicle comprises a vehicle body, a plurality of hydraulic supporting leg groups, a plurality of travelling wheel groups, a supporting switching structure and a girder carrying trolley; the vehicle body is provided with two outer side supporting girders and two inner side longitudinal girders which are parallel to each other, the two inner side longitudinal girders are located between the lower ends of the two outer side supporting girders, and a plurality of transverse girders are connected to the two outer side supporting girders and the two inner side longitudinal girders at intervals; a groove-shaped structure for storing a box girder is formed between the two outer side supporting girders; the multiple hydraulic supporting leg groups are arranged at the lower ends of the two outer side supporting girders at intervals from front to rear, and the multiple travelling wheel groups are connected to the lower ends of the two outer side supporting girders at intervals from front to rear; the supporting switching structure is provided with a front fixing supporting assembly anda plurality of rear fixing supporting assemblies, the front fixing supporting assembly is arranged on a cross girder at the front end of the vehicle body, and the multiple rear fixing supporting assemblies are arranged on all cross girders at the rear end of the vehicle body; and the girder carrying trolley is provided with a front girder carrying trolley body and a rear girder carrying trolley body, and the front girder carrying trolley body and the rear girder carrying trolley body are movably arranged on the two inner side longitudinal girders. The tunnel passing girder transporting vehiclecan solve the problem of passing a tunnel of a transporting vehicle carrying large-span and large-tonnage box girders.

Description

technical field [0001] The invention relates to the technical field of railway construction machinery and equipment, in particular to a tunnel beam transport vehicle. Background technique [0002] In the process of my country's high-speed railway bridge construction, when passing through towns, transportation hubs, soft soil and southern water network areas, long-distance bridging methods are often used to pass through. At present, the maximum weight of high-speed railway box girder is 900t, and the span is 32m. In the prefabricated erection technology system of simply supported box girders with a span of 32m, the construction of bridge piers and foundations, and the prefabrication of box girders play an important role in the construction of high-speed railways. Considering the construction cost of bridge piers in mountainous areas, the construction cost of pier pile foundations in soft soil and southern water network areas, and the land occupation of bridge construction, t...
