Gantry system of tunnel lining trolley

Abstract

The invention provides a gantry system of a tunnel lining trolley. The gantry system comprises a support frame, a gantry longitudinal beam, jacking mechanisms and transverse beam connecting beams. The support frame comprises a plurality of single support frame bodies, each single support frame body comprises a gantry transverse beam and two gantry upright columns, the two gantry upright columns of each single support frame body are symmetrically arranged, the gantry transverse beams are perpendicular to the gantry longitudinal beam and are positioned right above the gantry longitudinal beam, and the gantry upright columns are vertically arranged among the gantry transverse beams and the gantry longitudinal beam; the transverse beam connecting beams are parallel to the gantry longitudinal beam and are arranged on the gantry transverse beams; flange plates are arranged on the side surfaces of the gantry upright columns, and two groups of through holes which are used for mounting supporting jack seats and supporting cylinder seats are equidistantly formed in each flange plate; the jacking mechanisms are arranged at two ends of the gantry longitudinal beam. The gantry system has the advantages that the gantry system is simple in integral structure; the supporting jack seats and the supporting cylinder seats can be conveniently vertically adjusted owing to the through holes, so that requirements of different working conditions can be met, and the gantry system is high in practicality; supporting jacks and supporting cylinders can be flexibly mounted and adjusted, accordingly, the construction cost can be greatly lowered, and the labor intensity can be greatly relieved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a door frame system of a tunnel lining trolley. Background technique [0002] The tunnel building trolley is a special equipment that must be used in the secondary lining during the tunnel construction process, and is used for the lining construction of the inner wall of the tunnel. Due to differences in construction environment and construction requirements, the cross-sectional profile of each tunnel is often different, and the requirements for various parameters such as the appearance, shape, size, and stress of the tunnel lining trolley are also different. Therefore, the tunnel lining platform The car needs to be redesigned or processed and integrated according to the actual outline requirements, which greatly increases the construction cost. In addition, the lining of the tunnel-building trolley to a certain length or the deformation of the formwork will greatl...

Problems solved by technology

Due to differences in construction environment and construction requirements, the cross-sectional profile of each tunnel is often different, and the requirements for various parameters such as the appearance, shape, size, and stress of the tunnel lining trolley are also different. Therefore, the tunnel lining platform The car needs to be redesigned or processed and integrated according to the actual outline requirements, which greatly increases the construction cost

In addition, the lining of the tunnel-building trolley to a certain length or the deformation of the formwork will greatly reduce the accuracy of the tunnel-building trolley, which will greatly affect the lining quality of the tunnel, resulting in unqualified tunnels, and the repair of the tunnel-building trolley is difficult , the recycling cost is too high, which not only causes expensive construction costs, but also causes a waste of resources
