Excavation vertical frame lifting and placing vehicle

Abstract

The invention discloses an excavation vertical frame lifting and placing vehicle. The excavation vertical frame lifting and placing vehicle comprises a vehicle main body, guide rails, vertical frame bearing trolleys and lifting devices; a stretchable platform is installed at the upper end of the vehicle main body in a stretchable mode, and a jacking mechanism is connected to the stretchable platform; and the lifting devices are used for lifting a vertical frame and sending the lifting frame to the vertical frame bearing trolleys; the vertical frame bearing trolleys are installed on the guide rails and can transversely move so as to convey the vertical frame along the guide rails, the vertical frame bearing trolleys are connected with translation driving mechanisms, and the translation driving mechanisms can drive the vertical frame placed on the vertical frame bearing trolleys to transversely move and can convey the vertical frame to the position above the jacking mechanism in the retraction state. The excavation vertical frame lifting and placing vehicle has the advantages that the integration degree is high, the installation automation degree is high, the erection efficiency of the vertical frame is high, the manual operation is reduced, and the potential safety hazard of construction is reduced.

Description

technical field [0001] The invention relates to the field of stand installation equipment, in particular to an excavation stand lifting vehicle. Background technique [0002] At present, in the tunnel excavation process, in order to prevent the rocks on the upper wall of the tunnel from falling or even collapsing, it is necessary to erect an arc-shaped stand on the tunnel while digging to support the tunnel. Since there are multiple steps in the stand installation process, it usually takes Multiple machines can only be completed through cooperation, and the handover of the stand between multiple machines requires precise cooperation between multiple machines, and due to the complex terrain of the tunnel excavation site, there are certain difficulties in precise cooperative work between machines, making The erection of the stand is quite troublesome to install, and usually when erecting, multiple manuals are required to assist in the installation, the installation efficiency ...
